Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 4, a roll changing and cloth releasing apparatus includes: the inclined roll-changing cloth-releasing mechanism 10 and the roll-changing connecting mechanism 20.

Wherein, the inclined cloth-changing and cloth-releasing mechanism 10 comprises:

two brackets 11 arranged symmetrically;

the sliding rails 111 are arranged at the tops of the brackets 10, and the sliding rails 111 are obliquely arranged;

a first steering wheel 112 and a second steering wheel 113 arranged at two ends of each sliding rail 111, and a third steering wheel 114 and a fourth steering wheel 115 arranged at the bottom of each sliding rail 111;

a drive chain 13 provided around the first diverting pulley 112 to the fourth diverting pulley 115;

a motor 12 driving the transmission chain 13;

and the driving part 134 is arranged on the transmission chain 13, and the driving part 134 is used for placing a rotating shaft of the cloth roll 50/51 and driving the rotating shaft to move under the driving of the transmission chain 13.

The support 11 is mainly used for supporting the overall weight of the cloth roll 50/51, and can be of a steel frame structure. As a further improvement, in one embodiment, in order to reduce the overall weight of the bracket 11, the middle portion of the bracket 11 further includes a hollow-out portion 119, so that the bracket 11 is integrally formed into a structure similar to a "clip".

Two ends of the slide rail 111 are respectively used for bearing the working cloth roll 50 and the standby cloth roll 51. In particular, the top end of the slide rail 111 is used for carrying the standby cloth roll 51, and the bottom end is used for carrying the working cloth roll 50. This is advantageous in that, because the slide rail 111 is disposed obliquely, when the working yardage roll 50 is used up, the standby yardage roll 51 can slide to the bottom end of the slide rail 111 under the traction of the transmission chain 13 under the action of gravity to serve as the working yardage roll, so that the lifting effect of the machine can be greatly reduced, and the cost can be further significantly reduced. Preferably, the slide rail 111 forms an included angle of greater than or equal to 5 ° and less than or equal to 30 ° with the horizontal direction. This is because when the angle is too small, on the one hand, the gravity of the standby cloth roll 51 sliding downwards is small, and therefore the motor 12 is required to output large power; on the other hand, the inclined cloth-changing and unreeling mechanism 10 occupies a large area and area. When the included angle is too large, on one hand, the inertia of the downward sliding of the standby cloth roll 51 is large, so that the motor 12 or other locking mechanisms are easy to damage when braking; on the other hand, when the chain is in a stationary state during use, the motor 12 or other locking mechanism is subjected to a large load due to the large gravity, and is also easily damaged. More preferably, the sliding rail 111 forms an included angle of 15 ° or more and 25 ° or less with the horizontal direction. In one embodiment, the sliding rail 111 forms an angle of about 20 ° with the horizontal direction.

The first diverting pulley 112, the second diverting pulley 113, the third diverting pulley 114 and the fourth diverting pulley 115 form a quadrilateral mechanism, so that the transmission chain 13 arranged around the first diverting pulley 112 to the fourth diverting pulley 115 also forms a quadrilateral mechanism.

The type of the motor 12 is not limited as long as the motor can drive the transmission chain 13. As a further improvement, the inclined change-over unreeling mechanism 10 further includes a locking mechanism for locking the standby cloth roll 51 when the standby cloth roll 51 slides down to the lowermost working position, so as to switch the standby cloth roll 51 to the working cloth roll 50. Further, the locking mechanism and the motor 12 can be linked, that is, when the standby cloth roll 51 slides down to the lowest working position and is locked by the locking mechanism, a control signal is sent to control the motor 12 to brake. The locking mechanism can comprise a microswitch, a first motor and a buckle arranged on a rotating shaft of the first motor. When the standby cloth roll 51 slides down to the lowest working position, the microswitch is triggered, the microswitch sends out a control signal to control the first motor to rotate so that the buckle arranged on the rotating shaft of the first motor floats upwards to abut against the rotating shaft of the standby cloth roll 51, and simultaneously sends out a control signal to control the motor 12 to brake.

A abdicating groove 116 for the rotating shaft of the working cloth roll 50 to pass through is further formed between the connecting line of the second steering wheel 113 and the third steering wheel 114 and the bracket 10. The receding groove 116 is disposed at an inclined angle so that the rotating shaft of the work roll 50 can smoothly slide to the receiving portion 117 of the bottom without additional collision. Preferably, the receding groove 116 forms an included angle of 10 to 40 ° with the vertical direction. More preferably, the receding groove 116 forms an included angle of 20 to 30 ° with the vertical direction. In one embodiment, the offset groove 116 is formed at an angle of 25 ° to the vertical.

The receiving portion 117 includes a first connecting portion 1171 and a second connecting portion 1172, the first connecting portion 1171 is matched with the transmission chain 13 and is connected with the abdicating groove 116, so as to play a role of receiving the rotating shaft of the working cloth roll 50, the second connecting portion 1172 is lower than the first connecting portion 1171, so that the rotating shaft of the working cloth roll 50 can completely slide out smoothly under the action of gravity and cannot be clamped at the bottom of the bracket 11.

Referring to fig. 2, it is defined that the top of the slide rail 111 of the transmission chain 13 is point a, the bottom of the slide rail 111 of the transmission chain 13 is point B, and the connection position of the first connection portion 1171 and the second connection portion 1172 of the transmission chain 13 is point C, wherein the position of the rotation shaft of the cloth roll 50/51 from point a to point B to point C is driven by the motor 12 to move, rather than relying on its own gravity completely. This is because if the device relies on the gravity action of itself, the friction force between the two supports 10 and the two ends of the rotating shaft of the cloth roll 50/51 is different, which causes the rotating shaft of the cloth roll 50/51 to be stressed differently to generate "bias" and be blocked in the supports 10, thereby seriously affecting the production. Therefore, further, the transmission chain 13 is divided into three sections equally according to the positions of the points a, B and C, and the driving members 134 are respectively disposed on the transmission chain 13 at the points a, B and C. This is because when the driving chain 13 is driven from point a to point B, point B is just transmitted to point C, and the rotation shaft of the cloth roll 50/51 is just separated from the driving chain 13 and slides out from the second connecting part 1172, so that continuous production is realized. That is, the point C is provided at a connection between the second connection portion 1172 and the first connection portion 1171.

Referring to fig. 4, the transmission chain 13 includes a chain body 131, and a side plate 132 disposed on one side of the chain body 131; the side plate 132 is provided with a through hole 133 for fixing the driving member 134. The driving member 134 may be screw-engaged with the through hole 133 to achieve the fixing of the driving member 134. The driving members 134 may include two spaced apart driving members 134, the rotating shaft of the cloth roll 50/51 is disposed between the two driving members 134, and when the chain body 131 moves forward, the driving members 134 also move forward to drive the rotating shaft of the cloth roll 50/51 to move forward. The position of the chain body 131 at the slide rail 111 is arranged parallel to the slide rail 111, and the position is arranged lower than the slide rail 111, so that the pressure of the yardage roll 50/51 is borne on the slide rail 111, and the chain body 131 is not stressed. It will be appreciated that the drive member 134 projects beyond the surface of the track 111 to drive the shaft of the roll 50/51.

As a further improvement, the inclined roll-changing and cloth-releasing mechanism 10 further includes a first photoelectric sensor 14 for detecting whether the work cloth roll 50 is released completely, and if so, further controlling the roll-changing and connecting mechanism 20 to work.

As a further improvement, the inclined change-unwinding mechanism 10 further includes a second photoelectric sensor 15, which is disposed on the support 11 between the standby cloth roll 51 and the working cloth roll 50. The second photoelectric sensor 15 is configured to obtain a diameter of the standby cloth roll 51, when the unwinding of the working cloth roll 50 is finished and the roll-changing and docking mechanism 20 is docked successfully, the standby cloth roll 51 starts to operate for a predetermined time at a standby position, and when the second photoelectric sensor 15 detects that the diameter of the standby cloth roll 51 is lower than the predetermined diameter R, that is, when the diameter of the standby cloth roll 51 is operated for the predetermined time at the standby position, the standby cloth roll 51 starts to be controlled to switch from a standby position at the top to an operating position at the bottom. This has the advantage that the height of the change docking mechanism 20 can be reduced, which in turn reduces the volume of the entire change unreeling device. The first photosensor 14 and the second photosensor 15 are both related art, and will not be described in detail herein.

The roll-changing docking mechanism 20 includes:

a support plate 21; and

a first guide shaft 22, a cutting knife 23, a pressing part, a second guide shaft 25 and a third guide shaft 26 which are arranged on the supporting plate 21. The pressing piece comprises a first pressing head 24 and a second pressing head 27 which are arranged oppositely; the first guide shaft 22 and the second guide shaft 25 are respectively arranged at the top of the bottom of the first pressing head 24, and the cutting knife 23 is arranged between the first guide shaft 22 and the first pressing head 24; the third guide shaft 26 is disposed at the bottom of the second press-fitting head 27. The working cloth roll 50 sequentially passes through the first guide shaft 22, the cutting blade 23, the pressing part and the second guide shaft 25 to provide a working cloth 501 for the first tension adjusting mechanism 30. The spare cloth head 511 of the spare cloth roll 51 is fixedly arranged on the second pressing head 27 through the third guide shaft 26. Specifically, the spare cloth head 511 of the spare cloth roll 51 may be attached with a double-sided adhesive tape in advance, and the spare cloth head 511 of the spare cloth roll 51 is fixedly disposed on the surface of the working cloth roll 50 on the second pressing head 27 through the double-sided adhesive tape. When the first photoelectric sensor 14 detects that the working cloth roll 50 is completely unreeled, the pressing pieces are controlled to be mutually pressed, so that the working cloth 501 and the standby cloth head 511 are pressed together, and the cutting knife 23 is further controlled to cut the rest of the working cloth 501.

As a further improvement, the roll-changing and cloth-releasing device further comprises a first tension adjusting mechanism 30 for adjusting the overall tension of the working cloth 501. The first tension adjusting mechanism 30 includes a plurality of first reversing rotating shafts 32 horizontally disposed, a second reversing rotating shaft 33 disposed at the bottom of the first reversing rotating shaft 32, a third reversing rotating shaft 34 disposed at the upper portion of the first reversing rotating shaft 32, and a fourth reversing rotating shaft 35. The tension of the work cloth 501 is adjusted by reversing through the first reversing rotating shaft 32, the second reversing rotating shaft 33, the third reversing rotating shaft 34 and the fourth reversing rotating shaft 35, so that the tension is stably output. Specifically, in one embodiment, the working cloth 501 passes through the first reversing rotating shaft 32, the second reversing rotating shaft 33, the first reversing rotating shaft 32, the third reversing rotating shaft 34, the fourth reversing rotating shaft 35, and the third reversing rotating shaft 34 in sequence to reverse and adjust the tension, so that the tension is stably output

As a further improvement, the roll-changing and cloth-releasing device further comprises a cutting mechanism 40 for cutting the working cloth 501. The cutting mechanism 40 is a conventional art, and will not be described in detail herein.

Referring to fig. 5, an embodiment of the present invention further provides a control method for a roll-changing cloth-releasing device, including the following steps:

s1, controlling the working cloth roll 50 to be continuously unreeled;

s2, after the unwinding of the working cloth roll 50 is finished, controlling the roll changing and connecting mechanism 20 to press the working cloth 501 and the standby cloth head 511 together, and further controlling the cutting knife 23 to cut the rest of the working cloth 501;

and S3, controlling the motor 12 to work to enable the standby cloth roll 51 to slide to a working position, and at the moment, enabling the rotating shaft of the working cloth roll 50 to slide to the receiving part 117 through the abdicating groove 116 for recycling. The control method of the invention has the characteristics of energy consumption reduction, energy saving, environmental protection, easy industrial production and the like.

In step S1, whether the unwinding of the work cloth 501 of the work cloth roll 50 is finished may be continuously detected by the first photoelectric sensor 14, so as to determine whether the unwinding of the work cloth roll 50 is finished. Referring to fig. 3, the first photosensor 14 in fig. 3 continuously sends out a signal to detect whether the discharging of the work cloth 501 is finished, and when the first photosensor 14 does not detect the signal, it indicates that the discharging of the work cloth 501 is finished.

In step S2, since the double-sided tape is attached to the spare cloth head 511 in advance, when the first photoelectric sensor 14 detects that the working cloth roll 50 is completely unwound, the pressing members are controlled to be pressed against each other, so that the working cloth 501 and the spare cloth head 511 are pressed and bonded together, and the cutting knife 23 is further controlled to cut the remaining cloth of the working cloth 501.

In step S3, the controlling the motor 12 to operate to slide the standby cloth roll 51 to the operating position specifically includes:

s31, acquiring the diameter of the standby cloth roll 51 through the second photoelectric sensor 15, and controlling the motor 12 to work to enable the standby cloth roll 51 to slide to a working position when the diameter of the standby cloth roll 51 is smaller than a set value R; otherwise, the standby cloth roll 51 is controlled to work at the standby position for a preset time, until the diameter of the standby cloth roll 51 is smaller than the set value R, and then the motor 12 is controlled to work to enable the standby cloth roll 51 working at the standby position to slide to the working position.

It is understood that, in step S31, the diameter of the general roll is defined as R, and therefore, the set value R may be 0.5R to 0.8R. In one embodiment, the set value R may be 0.7R. Since the diameter of the roll is generally about 100cm, the set value R may be about 50 to 80 cm. In one embodiment, the set value R may be 70cm. That is, in step S31, when the diameter of the input cloth roll 51 is 70cm, the motor 12 is directly controlled to operate to slide the cloth roll 51 to the operating position; when the diameter of the input cloth roll 51 is 100cm, the cloth roll 51 is controlled to work in the standby position for a preset time till the diameter of the cloth roll 51 is less than 70cm, and then the motor 12 is controlled to work to slide the cloth roll 51 working in the standby position to the working position.

After step S3, the method may further include:

when the motor 12 is controlled to work to slide the standby cloth roll 51 to the working position, the other standby cloth roll 51 is placed to the standby position, and then the standby cloth head 511 is attached to the double-sided adhesive tape in advance and fixedly arranged on the second pressing head 27.

The cutting mechanism 40 cuts the work cloth 501 to form a plurality of parallel arranged dry paper towels 502. The dry tissues 502 arranged in parallel enter the tissue folding mechanism 60 to be folded, and finally the folded dry tissues 502 are soaked by liquid and cut into wet tissues in sections.

Referring to fig. 6-8, fig. 6 is a schematic structural diagram of a tissue folding mechanism 60, which includes a frame 61, a second tensioning mechanism 62, a first folding assembly 63, a second folding assembly 64, a folding roller 65, and a conveyor belt 66. The second tensioning mechanism 62, the first folding assembly 63, the second folding assembly 64, the folding rollers 65, and the conveyor belt 66 are disposed on the support 61.

The second tension adjusting mechanism 62 is used for receiving a plurality of dry paper towels 502 arranged in parallel after being cut by the cutting mechanism 40. In one embodiment, the second tension adjusting mechanism 62 includes a first roller 621, a second roller 622, and a third roller 623, wherein the first roller 621 is disposed on top of the second roller 622, and the third roller 623 is disposed in front of the second roller 622. The plurality of parallel arranged dry tissues 502 sequentially pass through the first roller 621, the second roller 622 and the third roller 623 and enter the first folding assembly 63.

The first folding member 63 forms a first slit of a broken line type. The first slit is used for accommodating the dry paper towel 502, and the total length of the first slit is matched with the width of the dry paper towel 502. Since the first slit is a fold line, the dry tissue 502 is pre-folded once at the first slit. The dry tissue 502 after one pre-folding enters the second folding assembly 64 for a second pre-folding. The second folding members 64 also form second slits of a zigzag type. The second slit pre-folds the dry tissue 502 a second time. The number of the fold lines of the second slit is the same as that of the first slit, and the angle of the fold line of the second slit is smaller than that of the first slit, so that the dry tissue 502 can be folded in the same number of folding layers. Finally, the dry towel 502 after the second pre-folding is folded into the corresponding number of plies by the folding roller 65 and the conveyor belt 66. Compared with other folding mechanisms, the folding assembly provided by the invention is folded for the second time through the fold line type gap, so that the use of other deviation rectifying mechanisms is avoided, repeated deviation rectifying is not needed, the dry tissue 502 in the vertical direction is transversely output after being folded, and the continuous automatic efficient production of the wet tissue is realized. The number of folding lines formed by the first folding component 63 and the second folding component 64 can be 2-8. Preferably, the number of the folding lines formed by the first folding unit 63 and the second folding unit 64 may be 3-5. Too much bending quantity easily causes uneven friction force, and further causes the phenomenon of deviation to influence production. In one embodiment, the first folding unit 63 and the second folding unit 64 each include 3 folding lines, so that the dry tissues 502 can be folded into 3 folds (layers).

Specifically, the first folding assembly 63 includes:

a first folding plate 631, one side of the first folding plate 631 having a first fold line portion 6312;

and a second folding plate 632 having a second fold portion 6322 corresponding to the first fold portion 6312, wherein a first gap is formed between the first fold portion 6312 and the second fold portion 6322.

Specifically, the first folding plate 631 further has first rectangular locking holes 6311 arranged in parallel, the second folding plate 632 further has second rectangular locking holes 6321 arranged in parallel, and the first folding plate 631 and the second folding plate 632 are fixedly disposed on the supporting frame 633 through the rectangular locking holes and the bolts 634. It can be understood that the width of the first gap can be adjusted by the arrangement of the first rectangular locking hole 6311 and the second rectangular locking hole 6321. The number of the first folding line portions 6312 and the second folding line portions 6322 may be selected according to the number of layers to be folded, and is preferably 2 to 6. In one embodiment, 3 first fold portions 6312 and 3 second fold portions 6322 are included. An included angle between two adjacent first folding line portions 6312 or second folding line portions 6322 is α, preferably, the value of α is 70 to 110 °, and more preferably, the value of α is 80 to 100 °. In one embodiment, α is about 90 °. It can be understood that the first fold portion 6312 and the second fold portion 6322 can be controlled by the angle to pull and limit the dry tissue 502, thereby preventing the dry tissue from deviating. Tests prove that when the value of alpha is too small, the generated friction force is too large, and the phenomenon of deviation caused by uneven friction force is easily caused.

Specifically, the second folding assembly 64 includes:

a third folding plate 641 having a third folding line portion 6412 on one side of the first folding plate 641;

and a fourth folding panel 642, wherein the fourth folding panel 642 has a fourth fold portion 6422 corresponding to the third fold portion 6412, and a second gap is formed between the third fold portion 6412 and the fourth fold portion 6422.

Specifically, the third folding plate 641 further has a third rectangular locking hole 6411 disposed in parallel, the fourth folding plate 642 further has a fourth rectangular locking hole 6421 disposed in parallel, and the third folding plate 641 and the fourth folding plate 642 are fixedly disposed on a supporting frame 643 through a rectangular locking hole and a bolt 644. It can be understood that the width of the second gap can be adjusted by the arrangement of the third rectangular locking hole 6411 and the fourth rectangular locking hole 6421. The number of the third fold portions 6412 and the fourth fold portions 6422 may be selected according to the number of layers to be folded, and is preferably 2 to 6. In one embodiment, 3 third creases 6412 and 3 fourth creases 6422 are included. The included angle between two adjacent third folding portions 6412 or fourth folding portions 6422 is β, preferably, β is 10 to 50 °, and more preferably, β is 15 to 30 °. In one embodiment, β is approximately 20 °. It can be understood that, by controlling the angle, the third fold portion 6412 and the fourth fold portion 6422 can pull and limit the dry towel 502, thereby preventing the dry towel from deviating. Tests prove that when the angle beta is too small, the friction force generated by the second folding assembly 64 in the folding process is too large, so that one side is stressed unevenly, and the side is prone to deviation.

The first folding unit 63, the second folding unit 64, and the folding rollers 65 may be disposed on the bracket 61 in pairs, so as to stack the folded dry tissues 502, and then perform subsequent soaking and cutting. The number of the first folding assembly 63, the second folding assembly 64, and the folding rollers 65 which are provided in pairs is not limited, and may be 1 to 20 pairs, which is not significant here, and in one embodiment, includes 3 pairs of the first folding assembly 63, the second folding assembly 64, and the folding rollers 65.

Both the working cloth roll 50 and the reserve cloth roll 51 are large-size cloth rolls, and the width of the cloth rolls is more than or equal to 500 mm. Typically up to about 1500 mm.
