Description
Technical field
The invention belongs to the uncoiling field of sheet metal strip, belong to large group of the B21C47 of IPC classification number, also can be used for the uncoiling field of the industries such as weaving, printing and dyeing, papermaking, plastics, particularly relate to a kind of unwinding and rewinding machine swelling device and both arms initiative rolling-unrolling machine.
Background technology
At present, along with the fast development of Flux-cored Wire Industry, flux-cored wire manufacturer more and more payes attention to the non-cutting time of minimizing equipment operation, to enhance productivity.Wherein reducing required time and the replacement frequency of each replacing steel coil strip is one of them important means.So emerged in recent years, use exoskeletal accurate after-combustion steel coil strip to unreel, this steel coil strip can directly utilize steel band itself to form steel coil strip, and after steel band all discharges, on unreeling machine, what is not remaining, can directly put new steel coil strip again.Also can adopt the inner tube of a tyre of paper web as steel coil strip, steel band is back and forth wrapped on paper web, forms steel coil strip, and after steel band all discharges, from unreeling machine collection last time cylinder, paper web can also be used for being again wound around new steel band.Make to carry out in this way unwinding and rewinding and not only reduced workman and push to, push time and the labour intensity of I-beam wheel, and while having solved I-beam wheel as the carrier of steel coil strip, the turnover problem of I-beam wheel and the consumption problem of I-beam wheel.
But existing both arms are put with machine, have plenty of existing single head is put to the repeated combination with machine, for example CN201105294Y " two reel uncoiler " discloses the two reel uncoilers in a kind of cold-strip steel uncoiling field, it contains two cover running parts, two cover reel parts, a set of telescopic section, divide into rotating part, left, mandrel in the main shaft of right reel is connected respectively with the cylinder bar of telescopic oil cylinder by a pair of thrust bearing, left, the running part of right reel and telescopic oil cylinder are fixed on revolving body simultaneously, telescopic oil cylinder is with left, the dead in line of the mandrel of right reel, be fixed on the top of revolving body, the casing of two cover reels is separately fixed at the both sides of revolving body.Its two cover reels, discontinuous operation, when a reel is normally worked, another reel upper volume simultaneously, has omitted service working time, thereby has improved production efficiency, has not only reduced the floor space of production line, and has saved equipment investment.
The design of this uncoiler is straight and narrow, and the device such as brake gear, transmission device is available in all varieties, but wherein the main shaft of reel is fixed on casing by bearing.This equipment is by (though the not directly explanation in literary composition of two self-aligning roller bearings, but the technical staff in this area can be from Figure of description unquestionable definite bearing type) be arranged on two risers of casing, and main shaft and reel (bearing the part of steel coil strip weight) lean out casing, formed cantilever beam structure, the cantilever beam structure of this and single-arm uncoiling machine is actually duplicate.Designer overlaps common single-arm uncoiling machine back-to-back.Caused so in other words conj.or perhaps apart from the bearing part nearer shaft strength nearer apart from reel very large.For addressing this problem, or use the strongly-typed bearing of bearing capacity instead, or use larger sized bearing instead, the two all can increase the manufacturing cost of equipment; Just to sacrifice bearing life as cost.
And adopting this structure will cause the length of rotatable body of both arms unreeling machine larger, this rotatable body has comprised two cover running parts, two cover reel parts, a set of telescopic section.On the one hand, greatly increased the weight of the weight of rotatable body, from two huge gussets (the limit switch of each side is arranged on gusset), just can find out, if not so large casing, so heavy casing, supports without so large gusset so.Thereby make to utilize manpower to turn round and become impossible, thus just must cause it to need motor to drive above-mentioned these rotatable bodies to turn round, and then another step has caused the complexity of equipment.On the other hand, it is that main bearing part and the distance of the centre of gyration have increased greatly that this structure makes reel, heavier part is shifted out to the scope that base contacts with ground outward, if only have the steel coil strip of a side on unreeling machine, and the steel coil strip of opposite side has been finished, the equipment center of gravity that has comprised so steel coil strip will deflect away from the support scope of base, so will improve greatly like this risk that equipment topples.
In addition, this unreeling machine adopts wedge expanding-contracting type mechanism swelling steel coil strip: wedge expanding-contracting type mechanism comprises a three-jaw inclined wedge-shaped structure, oblique expansion block is connected with dovetail shaped drift slot with interior wedge, in mobile wedge can promote that oblique expansion block is opened or oppositely mobile in wedge oblique expansion block is retracted, and can realize self-locking by wedge angle, the interior swelling mode of this structure is generally applied on the uncoiler of large-scale heavy duty.This uncoiler is all to adopt cantilever structure, in order to guarantee to bear heavier coil of strip, that for the main shaft of load-bearing, will do is thick, in addition, process oblique expansion block and interior wedge bothers very much, and by inclined-plane, slide to realize the harmomegathus of three-jaw, wearing and tearing are large, need to carry out specific surface treatment to rubbing surface, cause the uncoiler of this large-scale heavy duty expensive, bulky, as can be seen here, for the lighter situation of coil of strip, adopt the uncoiler of this swelling mode extremely uneconomical, be unfavorable for promoteing the wider application.This interior swelling mode also needs often to add lubricating oil to be safeguarded, otherwise very easily wears away the inclined working of oblique expansion block and interior wedge, causes shorten service life.
And, in existing rolling/unreeling machine, if there is employing cylinder/hydraulic cylinder to realize the swelling function of swelling watt, all do not there is auto-lock function.That is, when the gas circuit/fluid pressure line being connected when cylinder/hydraulic cylinder or with it occurs to reveal, the air pressure or the hydraulic pressure that in cylinder body, act on piston decline, and swelling watt will lose enough tension forces.When swelling watt loses enough tension forces, for the machine of vertical unreeling/rolling, still can be due to the deadweight of material volume, material volume still can be positioned in swelling watt (or being referred to as reel).But for the machine of unreel/rolling of level, the reasons such as the tension force while being easy to due to rolling/unreel or the whirling vibration of machine cause material volume to fly out or expect that volume scatters, once roll up and occur to fall apart, generally raw material cannot be reverted to original state again, so this just causes serious security incident or causes serious wastage of material.
If but simply cylinder/the hydraulic cylinder with auto-lock function is applied to unreel/winder field, can there is again following problem: 1, the self-locking of cylinder/hydraulic cylinder is only to keep the position of actuating strut motionless, and cannot guarantee to provide a lasting constantly active force to make swelling watt have enough tension forces to come the inner side of distensible material volume, and only meet swelling watt, can not retract, between swelling watt and material volume inner side, it is only the non-active tension force of simple support force initiatively, be actually like this rise not tight, for example the disclosed spool material retractable feeder of patent application 201010138295.0 does not just adopt self-locking cylinder to hold out against I-beam wheel, if the internal diameter of 2 material volumes is not completely unified, internal diameter is less than normal slightly, will cause the piston of self-locking cylinder/hydraulic cylinder full action to put in place, self-locking device cannot start, internal diameter is bigger than normal slightly, and after will causing the piston full action of self-locking cylinder/hydraulic cylinder to put in place, self-locking device starts, swelling watt also cannot be rolled up inner side by distensible material, also still should have more than is needed self-locking cylinder/hydraulic cylinder.
So self-locking cylinder/hydraulic cylinder is applied to unreel/winder field, avoid gas leakage or the impact of leakage on machine safety in operation and reliability, be that those skilled in the art thirsts for solving and the problem of failing to succeed always.

Above-mentioned support and contracting mechanism comprises that the inner is positioned at turnbarrel 27 ports and outer end is positioned at the sliding bearing chamber 13 outside this port of turnbarrel, and this sliding bearing chamber 13 is in axial sliding connection with turnbarrel 27, and internal-and external diameter cooperatively interacts, and relative rotation does not circumferentially occur.In the outer end of sliding bearing chamber 13, have a shaft shoulder on excircle, the inner of limit slippage bearing chamber 13 puts in the degree of depth of turnbarrel 27.The part that sliding bearing chamber 13 is positioned at outside port is that outer end portion is provided with outer gusset, between sliding bearing chamber 13 and every swelling watt inner reinforced plate 8, be equipped with swelling connecting rod 10, one end of swelling connecting rod 10 and swelling watt inner reinforced plate 8 is hinged, and the other end is hinged on the outdoor gusset 12 of sliding bearing.The swelling connecting rod 10 being connected with same swelling watt inner reinforced plate and support link 9 are positioned at same plane and are splayed arranges.
In sliding bearing chamber 13, from the inner, be provided with the two-direction thrust bearing 20, dish spring support ring 19, disk spring group 18 and the disc spring sleeve 15 that are sleeved on successively on pull bar 17, disk spring group 18 is contained in disc spring sleeve 15, disc spring sleeve is bowl-type, the bottom of bowl is sleeved on pull bar, and disc spring sleeve 15 is positioned at the outside of two-direction thrust bearing 20 and opening towards two-direction thrust bearing 20; The outer end of pull bar 17 passes the bottom of disc spring sleeve 15 and is provided with one section of external screw thread, is connected with nut 16 on the screw thread of pull bar outer end, the bottom outside adjacency of nut 16 and disc spring sleeve 15.
The inner ring of two-direction thrust bearing 20 is arranged between the first inner ring sleeve 21 and the second inner ring sleeve 22.The first inner ring sleeve 21 be sleeved on pull bar 17 in the mode that can axially outwards slide along pull bar 17, and between pull bar 17, be larger matched in clearance, causes unnecessary wearing and tearing to avoid the first inner ring sleeve 21 and pull bar 17 to come in contact.The second inner ring sleeve 22 suits are fixed on the first inner ring sleeve 21.The Outboard Sections of the first inner ring sleeve 21 outer walls is provided with a step surface, and this step surface props up the outside of two-direction thrust bearing 20 inner rings, and the lateral surface of the second inner ring sleeve 22 props up the inner side of two-direction thrust bearing 20 inner rings.The outer ring of two-direction thrust bearing 20 is arranged in sliding bearing chamber 13, and the outer end of sliding bearing chamber 13 is connected with bearing (ball) cover 14 by bolt, and this bearing (ball) cover 14 is a tubular construction, and the outer end of tubular is provided with flange, for being connected with the outer face of sliding bearing chamber; The inner of tubular props up the outer ring, outside of two-direction thrust bearing 20, for the location of this outer ring.
On pull bar 17, be also provided with a circlip for shaft 23, circlip 23 is positioned at the inner side of the first inner ring sleeve 21 and the second inner ring sleeve 22, for promoting the first inner ring sleeve 21 and the second inner ring sleeve 22.Before each material loading, pull bar is extrapolated, support reduction device is outwards moved, and then drive swelling watt to close up to facilitate upper volume by swelling connecting rod, because required thrust is little, so be provided with a circlip for shaft 23 on pull bar, the installation site of this circlip for shaft 23 is the inner side of swelling watt first inner ring sleeve 21 while strutting completely.When pull bar 17 moves laterally, circlip 23 promotes two-direction thrust bearing 20 by the first inner ring sleeve 21 and the second inner ring sleeve 22, two-direction thrust bearing 20 promotes sliding bearing chamber 13 by bearing (ball) cover 14, make to move outside sliding bearing chamber 13, drive the lower end of swelling connecting rod 10 outwards to move, swelling connecting rod 10 pulls swelling watt 7 downward translations, completes closing up of swelling watt, so that the smooth installation of steel coil strip.
When pull bar 17 moves to the inside, be threaded connection at the nut 16 of its end and promote disc spring sleeve 15, disc spring sleeve 15 by force transmission on disk spring group 18, the stressed contraction of disk spring group 18, active force is delivered to by dish spring support ring 19 on the first inner ring sleeve 21 being connected with two-direction thrust bearing 20, the first inner ring sleeve 21 passes to sliding bearing chamber 13 by two-direction thrust bearing 20 by power, move to the inside sliding bearing chamber 13, drive the lower end of swelling connecting rod 10 to move inward, swelling connecting rod 10 promote swelling watts 7 upwards translation open, complete the swelling process of material volume.
The length of above-mentioned disc spring sleeve 15 should guarantee when butterfly spring group 18 does not stress completely, distance between the bottom inside of disc spring sleeve 15 and two-direction thrust bearing 20 is greater than the decrement of butterfly spring, in order to avoid butterfly spring group 18 contacts with two-direction thrust bearing 20 because of disc spring sleeve 15 when compression, the problem that butterfly spring group 18 cannot continue compression occurs.
The supporting structure of above-mentioned turnbarrel 27 is selected single thrust bearing, in support and contracting mechanism, select the structure of two-direction thrust bearing, because in actual production process, swelling watt can not swelling be arrived angle as shown in Figure 1, can only swelling arrive the position as shown in the first half as left in Fig. 6, the size that this part represents is the theoretical internal diameter of material volume.If swelling is to the angle shown in Fig. 1, support link is vertical with the axis of pull bar 17, and swelling watt swelling is to full-size so.When the internal diameter size of steel coil strip is greater than theoretical size, that swelling watt just cannot swelling steel coil strip or has been tied with the inner tube of a tyre paper web of steel band.So in fact swelling watt can not swelling arrive full-size, should keep one to be less than the angle of 90 ° with axis, like this in order to bear the weight of steel coil strip and innermost layer steel band or paper web to be maintained to enough frictional force, support link and swelling connecting rod just produce an axial force to corresponding gusset, and be delivered on sliding bearing chamber 13 and turnbarrel 27, make the two have respectively the relative trend expanding outwardly, therefore in the supporting structure of turnbarrel 27 and in support and contracting mechanism, all should adopt thrust bearing for this trend, this thrust bearing can bear the axial force that this trend produces.Again because, when the thrust bearing in support and contracting mechanism also will bear pull bar and outwards moves, the second inner ring sleeve 22 imposes on its outside active force, therefore in support and contracting mechanism, the thrust axis in sliding bearing chamber 13 is promised and is adopted the two-direction thrust bearing that can bear bi-directional axial load, and the block bearing of turnbarrel 27 adopts single thrust bearing.
The installation form of the present embodiment to above-mentioned two-direction thrust bearing 20 and the force transferring structure of pull bar 17 are not limited to said structure form, also can adopt other mounting structure and force transferring structure, refer to Fig. 7, the inner ring of two-direction thrust bearing is arranged on the first inner ring sleeve 21, the first inner ring sleeve 21 is sleeved on pull bar 17 in the mode that can axially outwards slide along pull bar 17, the first inner ring sleeve 21 is in the outer outer ring of two-direction thrust bearing 20 and be provided with the shaft shoulder 172 for inwardly holding out against two-direction thrust bearing inner ring, butterfly spring group 18 acts on elastic force on the outer face of the first inner ring sleeve 21 indirectly by dish spring support ring 19.Said structure, also can cancel dish spring support ring 19, and butterfly spring group 18 directly acts on elastic force on the outer face of the first inner ring sleeve 21.Pull bar 17 is provided with second shaft shoulder 172 for outwards promoting two-direction thrust bearing 20, and this second shaft shoulder should be positioned at the inner side of the inner ring of two-direction thrust bearing 20.
In the present embodiment, start cylinder 33 has two groups, and every group has two.Refer to Fig. 1 and Fig. 5, for the start cylinder cylinder bar that drives left side pull bar, stretch out to the right, for driving the start cylinder cylinder bar of right side pull bar to stretch out left, for the start cylinder afterbody that drives left side pull bar, be arranged on left side vertical plate, for the start cylinder afterbody that drives right side pull bar, be arranged on right side riser.Two groups of four start cylinders 33 are arranged in casing alternately, become two cylinders of a group on a pair of linea angulata, cylinder bar all stretches out towards the pull bar direction away from by its drive, and hinged with the two side arms top of the horizontally disposed V-arrangement connecting plate 35 of center line, the bottom of V-arrangement connecting plate 35 is connected with pull bar 17.
Refer to Fig. 1, Fig. 8 and Fig. 9 (front view that Fig. 8 and Fig. 9 are connector and side view), the cylinder bar of start cylinder 33 is hinged with the side arm end of V-arrangement connecting plate 35 by connector 36, connector 36 is provided with the screwed hole 361 being connected with start cylinder bar along its length, broad ways is provided with two otic placodes that are parallel to each other 362, two otic placodes 362 are positioned at a side of screwed hole 361, on two otic placodes 362, be equipped with coaxial connecting through hole 363, this connecting through hole 363 is vertical with screwed hole 361, and vertical with otic placode 362.The head of start cylinder bar adopts this connector to be connected with V-arrangement connecting plate 35, but not commercially available common for connecting the Y-shaped connector of start cylinder club head and action component, can effectively reduce the length of start cylinder and the required annex of connecting plate, the final requisite space reducing in casing, for the length that the rotatable body of shortening both arms unreeling machine divides has been created advantage.Meanwhile, adopt the connector of this shape, can reduce the vertical range between the pin joint of start cylinder bar and connecting plate and the center line of revolving body, thereby reduced the bending moment of V-arrangement connecting plate 35 inside bottom, improved the bearing capacity of V-arrangement connecting plate 35.

In the present embodiment, the syndeton of casing and base, similar with disclosed syndeton in patent documentation CN201525655U, the present invention does not repeat them here.
The operation principle of the present embodiment is:
One) before steel belt for lifting volume, the start cylinder group of respective side is shunk, start cylinder drives pull bar to stretch out by connecting plate, circlip for shaft on pull bar promotes the first inner ring sleeve and the second inner ring sleeve, the second inner ring sleeve promotes the inner ring of two-direction thrust bearing, and promotes bearing (ball) cover by two-direction thrust bearing.Because bearing (ball) cover and sliding bearing chamber are connected, sliding bearing chamber is also along with bearing (ball) cover outwards moves together, the outdoor gusset of sliding bearing being packed on sliding bearing chamber also outwards moves thereupon together, angle between swelling connecting rod and axis reduces, angle between support link and axis reduces simultaneously, outwards move take the distance between support link and two pin joints of swelling connecting rod as the circular arc of radius on swelling watt edge, and the external diameter of simultaneously swelling watt also dwindles thereupon.When the inner reinforced plate of swelling watt and the outer gusset of turnbarrel contact, the external diameter of swelling watt is retracted to minimum of a value, and now start cylinder still may not shrink and put in place.
Because the axial location of inner side positioner on swelling watt gusset can regulate, so before steel belt for lifting volume, need to adjust the position of determining inner side positioner.If directly steel coil strip is placed in swelling watt, the standard of neither one location, workman determines the position of steel coil strip entirely by rule of thumb, so very possible bigger than normal or less than normal, if steel coil strip is excessively near apart from outer end, will cause swelling watt after swelling, the inner side of steel coil strip still cannot touch in the square tube of Internal baffle, steel coil strip does not have location, side, and the steel band keeping to the side most still likely subsides.If inner side positioner is excessively far away apart from outer end, although can utilize the square tube of Internal baffle accurately locates the side of steel coil strip, but can increase the distance of the friction of steel coil strip and swelling watt support, for there is no the steel coil strip of paper web, this is by the steel strip surface of inner side in heavy wear steel coil strip, and the wire feed when producing follow-up drawing work or using to flux-cored wire brings difficulty; For the steel coil strip that has paper web as the inner tube of a tyre, although there is not the problem of wearing and tearing steel strip surface, also can strengthen the wearing and tearing to recycled paper web.And except wear problem, when steel coil strip and swelling watt relatively move, frictional force needs the active force of start cylinder to overcome, and certainly can increase the load of start cylinder, likely causes the increase of start cylinder size.Increased after the positioner of inner side, can be after once adjusting to the right place, it is carried out fastening, during each upper volume, just had one reproducible, the position reference of accurate positioning, without again adjusting, can avoid above-mentioned problem.
Two) steel coil strip is placed in after the upper and axial location of swelling watt, start cylinder stretches out, and the connector on start cylinder bar drives connecting plate, and then drives pull bar to retract, and the nut of tie rod end compresses disc spring sleeve, disc spring sleeve compression butterfly spring group.Because butterfly spring group is not little when decrement will be more than lifting steel coil strip in other words in compressive state when pull bar stretches out completely, so now start cylinder is only to compress butterfly spring group by pull bar, and do not cause other variations.Certainly, if in order to reduce space in casing and the start cylinder of selection of small stroke, can cause start cylinder to shrink swelling watt inner reinforced plate while putting in place is still suspended from the outer gusset of turnbarrel, both can not dock, if in this case material volume is placed in swelling watt, can by outdoor sliding bearing, move by swelling connecting rod, by two-direction thrust bearing, the first inner ring sleeve, dish spring support ring, force transmission, on butterfly spring group, be compressed butterfly spring group.Certainly be likely also above the two combination, be the swelling watt inner reinforced plate segment distance that declines, by after one section of butterfly spring group compression, swelling watt inner reinforced plate falls to being placed on the outer gusset of turnbarrel, when then pull bar moves inward, then butterfly spring group is continued to one section of compression.
When compression stress suffered in butterfly spring group reaches steel coil strip need to be risen to required active force time, sliding bearing chamber is (this power is delivered on sliding bearing chamber by dish spring support ring and two-direction thrust bearing) under the elastic force effect of butterfly spring, in turnbarrel, move, and then by swelling connecting rod and support link, swelling watt is propped up, now the center of gravity of steel coil strip is constantly rising.
Angle when swelling connecting rod and support link are greater than these two connecting rods and have just started lifting steel coil strip with respect to the angle of axis while putting in place due to swelling watt swelling, so stressed (butterfly spring stressed) during swelling on connecting rod is less than the power while just starting lifting steel coil strip, the length of butterfly spring is greater than its length when just starting lifting steel coil strip, in the process of lifting steel coil strip, butterfly spring is in fact constantly, to discharge its decrement.Now butterfly spring group still has certain compression surplus.So watt by after complete steel coil strip swelling, start cylinder still continues to release a segment distance in swelling, pull bar continues to shrink inwards, disc spring sleeve compression butterfly spring group.Until reach start cylinder stroke, the lock of locking start cylinder interior is locked start cylinder, prevents that start cylinder from losing thrust because of gas leakage, the accident that causes material volume to fly out.In swelling watt, the length that after complete steel coil strip swelling, start cylinder bar continues to stretch out is to butterfly spring by the length of another compression.When the parts such as start cylinder, connecting plate, connector, pull bar are installed more accurately, this length is needed just less, and the second-compressed amount of spring is also just less, and pressure during final unreeling machine operation in butterfly spring group is also just less.For above-mentioned reasons, in unwinding and rewinding machine when operation,, in other words, the axial force after steel coil strip swelling is less, and after machine run gets up, the two-direction thrust bearing in outside and the thrust bearing of inner side stressed also less, is conducive to improve the thrust bearing life-span.
The generation of second-compressed amount is not only in order to make up the error while installing, and to have the effect that tension force is provided concurrently.Because if there is no second-compressed, elastic force on disk spring is only also to rest on due to material is rolled up in swelling process, overcoming swelling watt need to rise the center of gravity of material volume on needed gravity horizontal, if the active force of disk spring is also only in this level during the locking of start cylinder, that tension force to material volume will be the same (while not using butterfly spring group with not using butterfly spring group, the gravity that the tension force that can provide is only rolled up for material, due to swelling connecting rod, swelling watt, geometrical relationship between support link and pull bar, can not produce larger tension force, otherwise will cause structural damage) use so the advantage of disk spring group to give prominence to.And the generation of this second-compressed amount, the positive corresponding generation of additional tension force, and this tension force can not disappear because of the gas leakage/leakage of start cylinder, and this additional tension force exactly, guarantee that swelling watt and material volume can have enough frictional force between inner side (or material roll up paper web), control raising speed/reduction of speed that honest material convolution turns etc., improved the safety and reliability of system.For example, the weight of material volume is 1000 kilograms, when swelling watt will be expected the complete swelling of volume, active force in butterfly spring group is 800 kgfs, due to the second-compressed of butterfly spring group, the active force in butterfly spring group has increased again by 160 kgfs, has increased again so the tension force of 200 kgfs between swelling watt and material volume inner side, the frictional force that this has just increased between swelling watt and material volume inner side, has improved the unwinding and rewinding machines control ability to material volume velocity variations.
Because the uncoiler or the winder that adopt swelling watt distensible material volume inner core are different from I-beam wheel unwinding and rewinding machine.The material volume of I-beam wheel unwinding and rewinding machine is placed in I-beam wheel (or being referred to as drum), and the rotary speed of I-beam wheel is to embed in the hole in I-beam wheel by the finger on unwinding and rewinding machine, stirs I-beam wheel and rotates to regulate its rotating speed.And the frictional force that the rotating speed of the confidential adjusting material volume of the material retractable that adopts swelling watt can only be rolled up between inner core by swelling watt and material regulates its rotating speed, and frictional force is determined by tension force and coefficient of friction, and coefficient of friction be immobilize moving, so can only improve frictional force by increasing tension force, described in a upper paragragh, it is excessive that the tension force of the unwinding and rewinding machine of existing employing swelling watt form can not do.And technical scheme in employing the present embodiment, raising tension force that can be larger, and then the unwinding and rewinding machine that improves employing swelling watt form is rolled up the control ability of velocity variations to material, the acceleration that in the time of can adapting to speed governing, needs are larger and/or material are rolled up the larger occasion of rotary inertia, have expanded the scope of application of such machine.
Three) after swelling has operated; outer baffle is contained in swelling watt; utilize two abutment sleeves and two guide posts to realize the location to outer baffle; wherein two abutment sleeves have completed point location jointly; longer abutment sleeve has also completed the location that prevents swing; then use nut check, can play the protective effect of the outer side edges to steel coil strip.
Complete behind the location, outside of steel coil strip, can start initiatively folding and unfolding band.
Four) when the steel coil strip of a side discharges, step on pedal, make its rotation, limit shaft is displaced sideways in the zigzag groove of upper limit cover, and then step on pedal downwards, pedal overcomes the elastic force of spiral compression spring, drives limit shaft to move down in upper limit cover and lower limit cover, in the spacing hole of the upper end of limit shaft from box bottom, exits.And then stepping on pedal make its continue rotation, spacer pin is displaced sideways in the zigzag groove of upper limit cover, move to the right-hand part of the following horizontal stroke of zigzag, the top of spacer pin is stopped, so just can guarantee that spacer pin can upwards not skid off because of the elastic force of Compress Spring, cause limit shaft to protrude upward, disturb the rotation of casing.Then casing can be rotated.After casing is rotated in place, according to contrary sequential control motion of foot, can make spacer pin come back to Yi Heng left side, zigzag top, simultaneously again, drive limit shaft to move up in upper limit cover and lower limit cover, the upper end of limit shaft is stretched in the spacing hole on box bottom.Owing to having below this position, stop, so can guarantee that spacer pin can not skid off downwards, the phenomenon of effectively having avoided limit shaft to exit from spacing hole, makes casing location more reliable.
Butterfly spring group in the present embodiment also can be replaced by the elasticity of compression parts of other type, such as resilient sleeve etc.Nut 16 can be replaced by the limited block of pin joint.

Refer to Figure 13, be with the difference of embodiment 1, by floor installation, on reciprocating platform 62, the reciprocating motion of platform 62 can be by motor driven ball screws winding machine, also can be by motor-driven gear scrolling realization on tooth bar.In wrapup procedure, turnbarrel is when rotating, and base is also driven by ball screw framework or pinion and rack, moves back and forth, and realizes winding displacement.In general, while unreeling, base need not move back and forth, if but during actual use, the distance between machine and main frame is less, when the band with certain width should not swing, and also can be by floor installation on reciprocating mechanism.
Embodiment 4:
Be the positioner of outer baffle with the difference of embodiment 1.Refer to Figure 14～Figure 15, in the present embodiment, the positioner of outer baffle comprises and is sleeved on the outer locking of swelling watt watts 53, in locking watts 53, be connected with the holding screw and the backstay 54 that are pressed in swelling watt, backstay slides and is installed in spoke 56 through outer baffle inner ring 55, on spoke, be radially provided with slotted hole 561, in slotted hole, be provided with the lock-screw affixed with backstay.Locking watt compresses swelling watt by the holding screw on it and realizes locking, and backstay compresses spoke by the lock-screw on it and realizes location.
Above-mentioned outer baffle positioner, can avoid the large problem of embodiment 1 outer baffle positioner difficulty of processing.Because, in embodiment 1, outer baffle and turnbarrel are except the nested relationship of abutment sleeve and guide post, two incoherent parts completely, and overcoat has the outer baffle guide post of abutment sleeve still by riser, to be welded on turnbarrel, through this hot-working of welding, total just more likely produces new error because expand with heat and contract with cold, reduce the quality of fit of abutment sleeve and outer baffle guide post, increasing fit clearance needs to guarantee to install, thus, improved the unstability of outer baffle location; Raising machining accuracy, increases processing cost.The two scheme has certain drawback.
Outer baffle positioner in embodiment 1, owing to being provided with outer baffle guide post in the end of riser, once guide post is stressed, for riser, it is a cantilever beam structure of only having fixed at afterbody, and outer baffle guide post itself is also a cantilever beam structure of only having fixed at afterbody, this structure is very unfavorable for carrying.In order to reduce the negative effect of riser cantilever beam structure, can reduce the height of riser, if but reduce height, just need to increase the length of backstay in outer baffle positioner, and backstay itself is also a cantilever beam structure, if increase the length of backstay, certainly will reduce again its rigidity and bearing capacity.And outer baffle is after material volume is put on unreeling machine, be manually installed on unreeling machine, in order to reduce workman's work load, what need again as much as possible outer baffle to be done is lighter, so its material is also selected the material that density is less, intensity is poor or wall thickness is thinner, so that its rigidity is not easy to do is again too much.The two has just formed contradiction.
The present embodiment, the positioner of outer baffle is changed into the locking watt being directly sleeved in swelling watt, locking watt shape and size mate with swelling watt, how the circular outer diameter size no matter swelling watt forms changes, the shape of swelling watt itself is fixed, so locking watt can realize stable coordinating with swelling watt.And the variation of swelling watt external diameter is to make up by adjusting the position of backstay in spoke during swelling.The present embodiment by holding screw compress swelling watt realize locking watt location, simple in structure, easy to operate.
In the present embodiment, steel band outer baffle adopts plectane to add the structure that spoke adds inner ring, and the effect of spoke is equivalent to gusset.Steel band outer baffle also can adopt the structure of the outer ring+spoke+inner ring in embodiment 1.
Embodiment 5:
Refer to Figure 16, and the difference of embodiment 1 is: between dish spring support ring 19 and first shaft shoulder of pull bar, clamp and adjust packing ring 60, adjust packing ring 60 and be sleeved on pull bar 17.Dish spring support ring 19 does not directly contact with first shaft shoulder 171 of pull bar, but contact with the adjustment packing ring 60 for adjusted size, the internal diameter of adjusting packing ring 60 is identical with the external diameter of pull bar 17, the external diameter of adjusting packing ring 60 is identical with the internal diameter of the first inner ring sleeve 21, and can slide axially between the first inner ring sleeve 21.
In process of production, the internal diameter of steel band material volume can not be completely unified, and the present invention depends on and pulls the locking start cylinder of pull bar to move completely to put in place, utilizes lock in start cylinder to guarantee not occur the material volume accident that flies out.But the position that material volume internal diameter and pull bar pull is to have certain relation of interdependence, if the internal diameter of material volume is larger than theoretical value, after causing driving the start cylinder cylinder bar of pull bar to put in place, still cannot increase to position, even again discharge decrement by butterfly spring, also cannot guarantee, so just need to adjust the relative position of dish spring support ring and pull bar.For example, the position of dish spring support ring is outwards moved, need to increase and adjust thickness or the quantity of packing ring, make start cylinder when moving to terminal, the external diameter of swelling watt is less than original steel coil strip internal diameter; Vice versa.Adjust packing ring and can have various ways: 1) for certain material volume internal diameter size, calculate the every increase certain size of internal diameter (for example 1mm or 0.5mm), the thickness of needed adjustment packing ring, each adjusts the internal diameter of corresponding a kind of material volume of thickness of packing ring, when the internal diameter of steel coil strip changes to some extent, increase or reduce corresponding adjustment packing ring number; 2) size of required adjusted size packing ring while calculating respectively discharging volume internal diameter and be different size, makes respectively the adjustment packing ring of coil diameter in corresponding each steel band, when the internal diameter of steel coil strip changes to some extent, and integral replacing adjusted size packing ring.
Although by reference to the accompanying drawings the preferred embodiments of the present invention are described above, but the present invention is not limited to the above-mentioned specific embodiment, the above-mentioned specific embodiment is only schematic, be not restrictive, those of ordinary skill in the art is under enlightenment of the present invention, do not departing from the scope situation that aim of the present invention and claim protect, can also make a lot of forms, 1. with hinged-support, replace the swelling watt inner reinforced plate described in the present invention and the outer gusset of turnbarrel, be arranged on respectively the inner side of swelling watt and the outside of turnbarrel, and hinged with support link, play the effect of supporting swelling watt, 2. will for the cylinder number that struts each side swelling watt, change 3 or more number into, the cylinder that supports both direction is still crisscross arranged, 3. parts or the component combination in above embodiment with identical function are replaced mutually, formed the technical scheme that there is no Direct function description in above each embodiment, within these all belong to protection scope of the present invention.
