Preferably, the material stirring rods 16 are all arranged perpendicular to the outer surface of the first cutting device 1, and because the outer surface of the first cutting device 1 is obliquely arranged, the material stirring rods 16 are all obliquely and upwardly arranged from the outer surface of the first cutting device 1, so that the material stirring rods 16 can receive waste silk entering from the feed opening 31.

The fixed wheel 145 is arranged on the rotating shaft sleeve 121; when the rotating shaft 18 rotates, the rotating shaft 18 drives the connecting rod 142 to rotate; because the fixed wheel 145 is fixed, the relative position of the fixed wheel 145 and the transmission wheel 144 changes, so that the transmission piece drives the transmission wheel 144 to rotate, and the connection shaft 143 drives the cutting knife 141 to rotate; the cutting knife 141 rotates around the connecting shaft 143, thereby realizing the telescopic cutting of the cutting knife 141.
The telescopic cutting of the cutting knife 141 avoids the winding of the waste wire and the cutting knife 141 caused by the long-time extension of the cutting knife 141, so as to improve the cutting effect of the cutting knife 141; along with the telescopic swing of the cutting knife 141, the waste wire on the cutting knife 141 can be pulled away by the outer edges of the fixed part 12 and the rotating part 13, and simultaneously the waste wire on the gap between the fixed part 12 and the rotating part 13 is cut off by the cutting action of the cutting knife 141; meanwhile, the retraction of the cutter 141 also facilitates the waste wire cut at the upper end to fall to the bottom of the cylinder 3.
Preferably, the cutting assembly 14 is provided as a joint with a plurality of the connecting rods 142; preferably, four connecting rods 142 can be arranged on the connecting part, and the adjacent connecting rods 142 are vertically arranged, so that a cross-shaped structure is formed; the cutting knife 141 is arranged on each connecting rod 142; the driving wheels 144 corresponding to the cutting knives 141 have different setting heights, and the fixed wheels 145 have different setting heights, so that the simultaneous independent operation of the cutting knives 141 is ensured; preferably, the driving wheels 144 of each connecting rod 142 can share one fixed wheel 145, and a plurality of wheel parts are arranged on the fixed wheel 145 corresponding to the height of each driving wheel 144; the wheel part can be an annular groove or an annular tooth; the annular groove corresponds to the belt transmission part, and the annular teeth correspond to the chain transmission part. The cutting knives 141 are arranged at the same position, so that the waste wire on the same annular cross section can be cut at the same time, and the cutting effect of the first cutting device 1 on the waste wire is improved.
Example four
In order to ensure that the cutting knife 141 can effectively cut the waste silk between the fixed part 12 and the rotating part 13, the cutting knife 141 needs to extend out between the corresponding material stirring rods 16 on the fixed part 12 and the rotating part 13 so as to cut the waste silk wound on the two material stirring rods 16; and the material poking rods 16 are retracted at the position between two adjacent material poking rods on the same fixing part 12, so that the best cutting effect can be achieved. Therefore, the following relation is required:
wherein R is the radius of the fixed wheel 145; r is the radius of the driving wheel 144; theta is an included angle between adjacent material shifting rods 16 on the same fixed part 12 or the rotating part 13.
On the basis of the third embodiment, due to the influence of the length of the connecting rod 142 and the length of the cutting knife 141, the working sections of the cutting knife 141 which actually extend out and realize cutting are different; the number of the cutting knives 141 is actually distributed according to the working section so as to ensure that all the cutting knives can be cut on the same annular cross section; the annular cross section is a cross section between the fixed part 12 and the rotating part 13 where the cutting assembly 14 is arranged; the outer radius of the annular cross section is the radius size of the inner surface corresponding to the barrel 3, and the inner radius of the annular cross section is the radius size of the outer surface of the fixed part 12 or the rotating part 13.
Therefore, on the same annular cross section, the calculation formula of the setting number N of the cutting blades 141 is as follows:
wherein L is the inner circle radius of the annular cross section; l1Is the length of the connecting rod 142; l is2The length of the cutting knife 141; theta is the same as that of the adjacent material poking rod on the fixed part 12 or the rotating part 1316 are included.
Corresponding to the calculation formula of the setting number N, when the included angle between the adjacent material stirring rods 16 on the same fixed part 12 or the rotating part 13 is larger, it indicates that the space between the adjacent material stirring rods 16 is larger, and more cutting knives 141 are needed to ensure that the cutting knives 141 can completely cover all the ranges between the adjacent material stirring rods 16; and meanwhile, rounding is performed upwards, so that the minimum set quantity is set while complete coverage is realized, and the complex structure and the resource waste are avoided.
Since the end of the connecting rod 142 is provided with the connecting shaft 143, conditions to avoid interference between the connecting shaft 143 and the inner surface of the
fixed part 12 or the rotating
part 13 should be satisfied
Through the formula setting of the set number, the number of the cutting knives 141 capable of completely covering the annular cross section can be effectively designed according to the effective size of the first cutting device 1, so that the waste wires on the annular cutting surface can be effectively cut, and the cutting effect of the first cutting device 1 is improved.

The rotating disk 22 is connected to an output shaft of a motor 23 so that the fixed disk 21 and the rotating disk 22 rotate relatively.
As shown in fig. 6, fig. 6 is a structural view of the fixing plate; preferably, the fixed tray 21 is provided with a circular plate shape, and a plurality of through holes 211 are uniformly arranged on the fixed tray 21, when the cut small glass fibers are smaller than the cross sections of the through holes 211, the waste silk can smoothly pass through the through holes; the outer edge of the fixed disc 21 is further provided with a retaining ring 212, and the retaining ring 212 is connected with the outer edge of the rotating disc 22 through a bearing, so that the relative rotation of the fixed disc 21 and the rotating disc 22 is smoothly realized.
As shown in fig. 7 and 8, fig. 7 is a bottom view of the rotating disc of the present embodiment; FIG. 8 is a sectional view of the rotating disk of the present embodiment; the rotating disc 22 comprises a fixed ring 221, a plurality of sector plates 222 and a rotating sleeve 223; the sector plates 222 are uniformly distributed by taking the rotating sleeve 223 as a center, and the rotating sleeve 223 is sleeved on an output shaft of the motor 23; the fixing ring 221 fixes the outer edge of the sector plate 222, thereby improving the overall stability of the rotating disk 22. The fixing ring 221 of the rotating disk 22 is connected to the retainer ring 212 through a bearing.
The fixed disc 21 is also provided with a plurality of annular cutting pieces 213; the annular cutting pieces 213 are all arranged coaxially with the fixed disc 21; the bottom of the annular cutting piece 213 is fixedly connected to the upper surface of the fixed disc 21, and the cross section of the annular cutting piece 213 gradually tapers in a direction of separating from the upper surface of the fixed disc 21 to form a cutting sharp angle; correspondingly, the lower surface of the sector plate 222 of the rotating disc 22 is provided with a cutting block 224; the cutting blocks 224 are arranged in segments corresponding to the cutting pieces 213; the lower end surface of the cutting block 224 is designed in an arc shape, that is, the height of the two ends of the cutting block 224 is smaller than the height of the middle of the cutting block 224; the cutting block 224 is provided with a cutting groove 225 corresponding to the cutting member 213, the end of the cutting member 213 is provided in the cutting groove 225, when the waste silk falls on the fixed disc 21 from the space between the adjacent fan-shaped plates 222, the qualified waste silk directly falls from the passing hole 211, the unqualified waste silk falls on the cutting member 213, and the waste silk on the cutting member 213 and the cutting member 213 generate relative movement under the rotation of the rotating disc 22, so that the cutting member 213 cuts the waste silk; meanwhile, because the heights of the two ends of the cutting block 224 are small, the distance between the two ends of the cutting part and the cutting piece 213 is large, the waste wire on the cutting piece 213 enters the space between the cutting block 224 and the cutting piece 213 from the two ends of the cutting block 224, moves towards the middle of the cutting block 224 in the rotating process, and gradually decreases along with the distance between the cutting part and the cutting piece 213, so that the pressure between the waste wire and the cutting piece 213 is increased, and the cutting operation is realized.
The formula of the height change of the lower surface of the cutting block 224 is as follows;
wherein h is a height dimension corresponding to a point on the lower surface of the cutting block 224; x is the arc length dimension in the horizontal plane from a point on the lower surface of the cutting block 224 to the end of the lower surface of the cutting block 224, and H is the distance dimension between the lower surface of the rotating disk 22 and the upper surface of the fixed disk 21; a is the height dimension of the cutting member 213; b is the gap size; c is the arc length dimension of the two end parts of the lower surface of the cutting block 224 on the horizontal plane.
The size of the gap is generally set to be two to three times the diameter of the waste wire, thereby ensuring that the waste wire can smoothly enter between the cutting block 224 and the cutting member 213 from both end portions of the cutting block 224.
By setting the variation formula, when the length of the cutting block 224 increases, that is, the number of the cutting blocks 224 corresponding to the same cutting member 213 decreases, the length of a single cutting block 224 increases, and the arc length dimension of the two end portions of the lower surface of the cutting block 224 on the horizontal plane becomes longer, then the height dimension of the lower surface of the cutting block 224 decreases.
Through the setting of the variation formula, the shape design of the lower surface of the cutting block 224 can be effectively determined, so that the cutting of the waste wire by the cutting block 224 is facilitated.
The cutting block 224 arranged at the outermost side of the rotating disc 22 is arranged corresponding to the baffle ring 212, that is, the outer edge of the cutting block 224 and the inner edge of the baffle ring 212 are arranged in a close fit manner, so that waste silk is prevented from being accumulated between the baffle ring 212 and the outermost cutting block 224; meanwhile, the close fit between the cutting block 224 and the baffle ring 212 can also effectively improve the relative position stability between the rotating disc 22 and the fixed disc 21.
EXAMPLE six
Preferably, the fixed disk 21 is further provided with a plurality of material blocking portions 214; the material blocking parts 214 are straight plates, and the material blocking parts 214 are uniformly distributed on the fixed disc 21 along the radial direction; as shown in fig. 9, fig. 9 is a bottom view of the rotating disk according to the present embodiment; the cutting blocks 224 may be provided as cutting plates with cutting openings, which are uniformly distributed in the radial direction on the lower surface of the rotating disc 22; preferably, the cutting plates may be disposed at both linear side edges of the sector plate 222, and the cutting openings are disposed corresponding to the cutting members 213. The distance between the top of the material blocking part 214 and the lower surface of the rotating disc 22 is equal to the distance between the lower surface of the rotating disc 22 and the bottom of the cutting plate.
When the rotating disc 22 rotates, the cutting plate can drive the waste wire on the cutting part 213 to move, so that the relative cutting motion of the waste wire and the top of the cutting part 213 is realized, and when the cutting plate moves to the position of the material blocking part 214, due to the size setting of the cutting plate and the material blocking part 214, the cutting plate and the material blocking part 214 perform cutting operation on the waste wire between the cutting plate and the material blocking part 214, so that the size of the glass fiber is reduced.
EXAMPLE seven
As shown in fig. 10, fig. 10 is a bottom view of the rotating disk according to the present embodiment; the rotary disc 22 can also be provided as a circular plate provided with a plurality of screening holes 226, and the lower surface of the rotary disc 22 is provided with the cutting plate; the diameter of the screening hole 226 is larger than that of the passing hole 211, so that waste silk with larger size can firstly pass through the screening hole 226 and enter between the rotating disc 22 and the fixed disc 21, and then the waste silk is cut by the structure arranged between the rotating disc 22 and the fixed disc 21.
Preferably, the inner walls of the screening holes 226 and the passing holes 211 are provided as annular sharp edges, that is, the screening holes 226 and the passing holes 211 extend from the hole edges to the center of the screening holes 226 or the passing holes 211, and gradually decrease in thickness during the extension to finally form a sharp edge, when the same waste silk enters the screening holes 226 and the passing holes 211 simultaneously, due to the relative rotation of the rotating disc 22 and the fixed disc 21, the waste silk is cut by the sharp edges of the screening holes 226 and the passing holes 211 simultaneously, so that the waste silk with longer length is cut into waste silk with shorter size; the mutual cooperation between the cutting plate and the material blocking part 214 between the rotating disc 22 and the fixed disc 21 effectively cuts the waste silk between the screening holes 226 and the passing holes 211.
Specifically, when the same waste wire passes through the screening hole 226 and the passing hole 211 at the same time, the screening hole 226 and the passing hole 211 cut the waste wire due to the rotation of the rotating disk 22; generally, when the sharp edge vertically applies force to the waste wire, the cutting effect of the screening holes 226 and the passing holes 211 is best, namely, the screening holes 226 and the passing holes 211 passing through simultaneously are on the same vertical line when cutting is carried out; however, in most cases, because the screening holes 226 and the passing holes 211 passing through at the same time are not in a uniform vertical line, the sharp edges do not achieve the optimal force application effect, the waste silk generates relative sliding of axial planes in the screening holes 226 and the passing holes 211, so that the length of the waste silk between the rotating disc 22 and the fixed disc 21 is gradually increased, and the rotating disc 22 and the fixed disc 21 rotate relatively; the position between the screening hole 226 and the passing hole 211 which pass through the waste silk simultaneously is non-linear change, the waste silk correspondingly generates the relative sliding of a radial plane while sliding in the screening hole 226 and the passing hole 211, when the same waste silk simultaneously passes through the screening hole 226 and the passing hole 211, and the rotating disc 22 and the fixed disc 21 relatively rotate for a certain time, the sharp edge cuts into the surface of the waste silk under the relative sliding action of the radial plane and generates tearing under the relative sliding action of an axial plane, so that the waste silk is broken at the cutting inlet of the sharp edge. Meanwhile, as the hole cutting operation occurs after the rotating disc 22 and the fixed disc 21 rotate relatively, the cut waste silk has a long length in the rotating disc 22 and the fixed disc 21, and two ends of the cut waste silk are generally respectively positioned on the lower surface of the rotating disc 22 and the upper surface of the fixed disc 21, at this time, when the waste silk falls on the material blocking part 214, the cutting plate cuts the waste silk falling on the material blocking part 214; when the waste silk falls on the annular cutting piece 213, the cutting plate drives the waste silk and the cutting plate to relatively slide, so that cutting is realized; typically, these two cutting modes are performed simultaneously.
Example eight
The glass fiber waste wire crushing and processing equipment is also provided with a suction device 5, and the suction device 5 provides vertical downward suction to the waste wires in the first cutting device 1 and the second cutting device 2, so that the waste wires can pass through the screening hole 226 and the passing hole 211 more easily; meanwhile, a large downward pressure is provided, so that waste wire cut in the first cutting device 1 can fall down quickly; at the same time, the waste wire in the second cutting device 2 can slide relative to the annular cutting member 213 under a larger pressure, so that a better relative cutting effect can be realized.
Generally, said suction means 5 comprise a suction fan; the suction fan is arranged on the side edge of a discharge pipe 32 at the bottom of the barrel 3, a suction port is formed in the side edge of the discharge pipe 32, and an air suction port of the suction fan is connected with the suction port, so that the suction fan is communicated with the interior of the barrel 3; the suction port is also provided with a filter screen, so that waste silk is prevented from being brought into the suction fan under the action of wind power.
Preferably, the wall of the discharge pipe 32 is arranged obliquely, specifically, the diameter of the discharge pipe 32 gradually decreases along the vertical downward direction, and the air suction opening is arranged on the oblique wall of the discharge pipe 32; due to the oblique arrangement of the air suction opening, the suction fan generally provides a larger suction force to the first cutting device 1 and the second cutting device 2, rather than performing an air suction effect to the discharge opening at the bottom of the discharge pipe 32.
When the suction fan is right when the suction operation is implemented inside the barrel 3, the partially cut waste wire is adsorbed on the filter screen due to the action of wind power, and under the condition that the gravity is increased due to continuous accumulation of the waste wire, the waste wire finally slides down on the wall of the inclined discharge pipe 32 due to overlarge self gravity, so that the waste wire is guided out from the discharge hole.
Preferably, the suction fan can control the waveform suction, that is, the suction fan controls the suction to be in a waveform shape when working, and when the suction is gradually reduced, the waste silk slides down under the action of self gravity; thereby avoiding the waste silk from being accumulated on the filter screen for a long time.
Preferably, the suction fan is implemented as a control of pulse suction, that is, when the suction fan works, the flexible filter screen is vibrated by supplying force in stages, so that waste silk is prevented from being accumulated on the filter screen.
Example nine
The invention also specifically discloses a waste silk processing method, which comprises the following steps:
s1, the process starts: the waste silk falls onto the first cutting device 1 from the feed port 31 of the cylinder 3, and the suction device 5 is started;
s2, the first cutting device 1 cuts the waste wire: specifically, the braking member 17 drives the top cover 11 and the rotating portion 13 to rotate, the waste silk falls onto the material stirring rod 16, and is wound and pulled under the driving of the rotation of the top cover 11 and the rotating portion 13, so that the agglomerated waste silk is pulled open or broken; when the waste filaments are broken and become small-sized glass fibers, the small-sized glass fibers fall down to the second cutting means 2; when the waste filaments are drawn to form filaments and wound on the setting bar 16, the cutting knife 141 between the rotating part 13 and the fixed part 12 cuts the wound waste filaments in a stretching manner, thereby cutting the waste filaments into small-sized glass fibers.
S3, cutting the waste wire by the second cutting device 2; specifically, the cut waste silk falls between the rotating disc 22 and the fixed disc 21, the rotating disc 22 and the fixed disc 21 rotate relatively, and the cutting piece 213 and the cutting block 224 which are arranged between the rotating disc 22 and the fixed disc 21 cut the waste silk; or the cutting plate and the material blocking part 214 arranged between the rotating disc 22 and the fixed disc 21 cut the waste wire; the waste silk is cut by the screening holes 226 arranged on the rotating disc 22 and the passing holes 211 arranged on the fixed disc 21; when the cutting is completed, the glass fiber with the size is dropped into the discharging pipe 32 at the bottom of the cylinder 3 through the passing hole 211.
S4, crushing the glass fibers by the crushing apparatus 4: the discharging pipe 32 guides the small-sized glass fibers into the crushing device 4, and the glass fibers are crushed into glass fiber powder in the crushing device 4, and the glass fiber is regenerated through a next production line.
By the arrangement of the waste silk processing method, the waste silk is gradually cut into small-size glass fibers by the first cutting device 1 and the second cutting device 2, so that the subsequent crushing treatment of the crushing device 4 is facilitated, and the reproduction of the glass fibers is facilitated.
In the waste silk processing method of the present invention, the first cutting device 1 and the second cutting device 2 may adopt the specific structure of the glass fiber crushing device of the present invention at the same time, or only one of the first cutting device 1 and the second cutting device 2 may be adopted, and the other cutting device may adopt other reasonable cutting device forms in the prior art.
The foregoing is merely a preferred embodiment of the invention, which is intended to be illustrative and not limiting. It will be understood by those skilled in the art that various changes, modifications and equivalents may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
