Description

Technical Field

[0001] This invention relates to the field of fabric folding machine technology, specifically to an ultrasonic oblique-cutting and extracting square fabric folding integrated machine and its method. Background Technology

[0002] An automatic fabric slitting and stacking machine is a device used for automatically cutting and stacking fabrics. It is commonly used in the textile industry to automatically cut fabrics to set dimensions and then neatly stack the cut fabrics. This equipment can greatly improve production efficiency, reduce manual operation, and ensure the consistency of the size and quality of the cut and stacked fabrics.

[0003] For example, patent CN116654692A discloses an automatic fabric folding and cutting machine. It features a pressing device on the side of the feeding device to press the material downwards. A pressure strip is located below the pressing device, with its bottom connected to the top of the frame. The pressing assembly includes a connecting plate and a pressure plate. The bottom of the drive cylinder is vertically connected to the connecting plate, and a pressure plate is located below the connecting plate. During pressing, the material is pressed between the pressure strip and the pressure plate to tighten it, facilitating cutting. An auxiliary pressure column is also located below the connecting plate to further assist in pressing the material during cutting. However, the pressing structure of this automatic fabric folding and cutting machine interferes with the material conveying process, affecting the conveying of square fabric pieces. Existing fabric folding and cutting machines often simply stack square fabric pieces into piles, which easily scatter unevenly during movement, negatively impacting material packaging. Folded fabric pieces, on the other hand, allow users to extract and retrieve them, providing convenience.

[0004] Based on this, the present invention designs an ultrasonic oblique cutting extraction square fabric folding integrated machine and method to solve the above problems. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides an ultrasonic oblique-cutting extraction square fabric folding integrated machine and its method.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An ultrasonic oblique-cutting and extracting square fabric folding machine includes a first support frame and a second support frame; a first conveyor belt is installed on the first support frame, and a second conveyor belt is erected between the first and second support frames, the first and second conveyor belts are connected, the second conveyor belt is inclined, and a drop is provided between the first and second conveyor belts to prevent material wrinkling; a plurality of guide rollers are rotatably mounted on the second support frame through bearings and are evenly distributed, and a separating ring for separating and conveying two groups of materials is installed on the guide rollers;

[0008] The second support frame is equipped with a fabric cutting mechanism, the first support frame is equipped with a dual-worker material displacement mechanism, and two sets of material handling mechanisms are symmetrically arranged on both sides of the first support frame.

[0009] The material handling mechanism includes a linear module, a belt conveyor, a stacking plate, a fixed frame, a pressure plate, and a flipping assembly. The linear module and the fixed frame are fixedly installed on the first support frame. The moving end of the linear module is fixedly installed with the belt conveyor.

A set of flipping assemblies is provided on each side of the belt conveyor, and a stacking plate is movably connected to each set of flipping assemblies. A pad for auxiliary stacking is also provided on the stacking plate.

[0010] Furthermore, the fabric cutting mechanism includes a processing table, a cross-cutting device, a cross groove, an ultrasonic generator, a first fastening component, a second fastening component, and a tilting cylinder. The processing table is fixedly installed on one end of the second support frame near the first support frame and is tilted. The cross-cutting device is fixedly installed on the second support frame and mounted on the upper side of the processing table. The first fastening component is installed on the second conveyor belt, and the second fastening component is installed on the second support frame.

[0011] Furthermore, a transverse groove for the movement of the ultrasonic generator is provided on the processing table, and a tilting cylinder is fixedly installed on the lower side of the second support frame, with the output end of the tilting cylinder fixedly connected to the ultrasonic generator.

[0012] Furthermore, the first fastening assembly includes a first adjusting cylinder, a mounting bracket, a horizontal shaft, and pressure blocks. Two first adjusting cylinders are symmetrically fixedly installed on both sides of the second conveyor belt. The output end of the first adjusting cylinder is fixedly installed with a mounting bracket, and a horizontal shaft is fixedly installed between the mounting brackets. Multiple pressure blocks are evenly fixedly installed on the horizontal shaft at equal intervals.

[0013] Furthermore, the second fastening assembly includes a bracket, a fixed pressure roller, a movable pressure roller, an adjusting block, an adjusting groove, and a second adjusting cylinder. Two brackets are symmetrically fixedly installed on both sides of the second support frame. The brackets are provided with adjusting grooves that are slidably connected to the adjusting blocks. The top of the brackets is fixedly installed with the second adjusting cylinder, and the output end of the second adjusting cylinder is fixedly connected to the adjusting blocks. The fixed pressure roller is rotatably installed between the brackets through bearings, and the movable pressure roller is rotatably installed between the adjusting blocks through bearings.

[0014] Furthermore, the dual-workstation material transfer mechanism includes a crossbar, a slide bar, a belt linear module, a slide table, a material transfer cylinder, and a support. The crossbar is fixedly installed on the first support frame, and a slide bar is fixedly installed on the crossbar. A set of belt linear modules is fixedly installed on each of the front and rear sides of the crossbar. The two slide tables are symmetrically arranged and slidably connected to the slide bars for limiting their movement. The two slide tables are respectively fixedly connected to the moving ends of the two belt linear modules. A material transfer cylinder is fixedly installed on the slide table, and a support is fixedly installed on the output end of the material transfer cylinder. Multiple pneumatic grippers for clamping square fabric pieces are fixedly installed on the support.

[0015] Furthermore, the flipping assembly includes a bracket, a stacking cylinder, a first connecting rod, and a second connecting rod. The bracket is fixedly mounted on a first support frame, and the stacking plate is hinged to the top of the bracket. The first connecting rod is configured as a near-V shape, with one end of the first connecting rod hinged to the bracket and the other end of the first connecting rod fixedly connected to the second connecting rod; the other end of the second connecting rod is hinged to the stacking plate.

[0016] Furthermore, the lower end of the stacking cylinder is hinged to the first support frame, and the output end of the stacking cylinder is hinged to the corner of the first connecting rod.

[0017] Furthermore, at least four sets of guide rollers are provided, and the material is connected to the guide rollers in a wave-like pattern and separated into two strips by the dividing ring.

[0018] To better achieve the objectives of this invention, this invention also provides a method for an ultrasonic oblique-cutting and extracting square fabric folding machine, comprising the following steps:

[0019] Step 1: The material is connected to the guide roller in a wave-like pattern and separated into two strips by the dividing ring. Then it passes between the processing table and the cross-cutting device and falls onto the first conveyor belt.

[0020] Step 2: The first adjusting cylinder moves the horizontal axis closer to the first conveyor belt until the pressure block presses the material onto the first conveyor belt. At the same time, the second adjusting cylinder drives the adjusting block to move vertically downward in the adjusting groove, so that the movable pressure roller approaches the fixed pressure roller to clamp the material, so that the parts of the material on both sides of the cross-cutting device are clamped at the same time.

[0021] Step 3: The tilting cylinder drives the ultrasonic generator to extend from the transverse groove. The cutter of the transverse cutting device and the ultrasonic generator work together to cut the material into square cloth pieces. After the cutting is completed, the pistons of the first and second adjusting cylinders are reset to release the material. The tilting cylinder drives the ultrasonic generator to reset, and then the square cloth pieces are transported through the first and second conveyor belts.

[0022] Step 4: After the square fabric pieces are moved to the set position, the dual-worker shifting mechanism moves the two sets of square fabric pieces to the material handling mechanisms on both sides respectively. In the material handling mechanism on one side, half of the square fabric piece falls on the belt conveyor line, and the other half of the square fabric piece falls on the stacking plate on the left. Then, the dual-worker shifting mechanism grabs a new square fabric piece and releases it. At this time, half of the new square fabric piece falls on the belt conveyor line, and the other half of the square fabric piece falls on the stacking plate on the right. The flipping component is activated to drive the stacking plate on the left to flip, so that the part of the second-top square fabric piece that falls on the stacking plate folds onto the part of the top material that falls on the belt conveyor line. Then, the linear module drives the belt conveyor line to move vertically downward, so that each subsequent square fabric piece falls at the same height. The dual-worker shifting mechanism alternately places the material on the two stacking plates and repeats the above operation to make adjacent square fabric pieces fold and connect with each other.

[0023] Step 5: Once the number of stacked square fabric pieces reaches the set number, the belt conveyor moves the square fabric pieces to the bottom of the pressure plate and moves them vertically upward. With the help of the pressure plate, the stacked material is compacted, and finally the operator unloads the material.

[0024] The present invention has the following technical effects:

[0025] 1. In this invention, a dual-workpiece material transfer mechanism alternately places square fabric pieces on two stacking plates. With the cooperation of the linear module and the flipping component, adjacent square fabric pieces are folded together. Finally, the pressure plate compacts the fabric, realizing an automatic material handling process for finished products. This greatly improves production efficiency. The stacked finished products are tightly connected, making them neat, beautiful, easy to pack, and less prone to loosening. Moreover, users can retrieve the materials by pulling them out, greatly facilitating user use.

[0026] 2. In this invention, the material is clamped on both sides of the cutting part simultaneously by the cooperation of the pressure block, fixed pressure roller and movable pressure roller, so that the material will not be displaced during the cutting process and the accuracy of material cutting is ensured; and the cut square cloth pieces can fall smoothly from the inclined processing table onto the second conveyor belt, which facilitates the feeding process of the square cloth pieces.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The present invention will be further described below with reference to embodiments.

[0041] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0042] Example 1

[0043] Please refer to the instruction manual appendix. Figure 1 , 2 8. Ultrasonic oblique cutting and extraction square fabric folding integrated machine, including a first support frame 101 and a second support frame 102;

[0044] A first conveyor belt 203 is mounted on the first support frame 101, and a second conveyor belt 204 is erected between the first support frame 101 and the second support frame 102. The first conveyor belt 203 and the second conveyor belt 204 are connected. The second conveyor belt 204 is inclined, and a drop is provided between the first conveyor belt 203 and the second conveyor belt 204 to prevent material wrinkling. Multiple guide rollers 201 are rotatably mounted on the second support frame 102 through bearings and are evenly distributed. A separating ring 202 for separating and conveying two groups of materials is mounted on the guide rollers 201.

[0045] The second support frame 102 is equipped with a fabric cutting mechanism 3, the first support frame 101 is equipped with a double-worker material displacement mechanism 4, and two sets of material handling mechanisms 5 are symmetrically arranged on both sides of the first support frame 101.

[0046] The material handling mechanism 5 includes a linear module 51, a belt conveyor 52, a stacking plate 53, a fixed frame 54, a pressure plate 55, and a flipping assembly 56. The linear module 51 and the fixed frame 54 are fixedly installed on the first support frame 101. The belt conveyor 52 is fixedly installed on the moving end of the linear module 51. The pressure plate 55 is fixedly installed on the fixed frame 54 and is located on the upper side of the belt conveyor 52. A set of flipping assemblies 56 is provided on each side of the belt conveyor 52, and a stacking plate 53 is movably connected to each set of flipping assemblies 56. A pad for auxiliary stacking is also provided on the stacking plate 53.

[0047] In this invention, the material is connected to the guide roller 201 in a wave-like manner and separated into two strips by the dividing ring 202. After passing through the fabric cutting mechanism 3, the material is made into square fabric pieces, which are then conveyed by the first conveyor belt 203 and the second conveyor belt 204. The difference in drop between the first conveyor belt 203 and the second conveyor belt 204 is used to prevent the square fabric pieces from wrinkling during the conveying process, ensuring that subsequent operations on the square fabric pieces can be carried out smoothly.

[0048] After the square fabric pieces are moved to their set positions, the double-worker shifting mechanism 4 moves the two sets of square fabric pieces to the two side sorting mechanisms 5 respectively. In one side sorting mechanism 5, half of the square fabric piece falls onto the belt conveyor 52, and the other half falls onto the left stacking plate 53. Then, the double-worker shifting mechanism 4 grabs a new square fabric piece and releases it. At this time, half of the new square fabric piece falls onto the belt conveyor 52, and the other half falls onto the right stacking plate 53. The flipping component 56 is activated to drive the left stacking plate 53 to flip, so that the portion of the second-to-top square fabric piece that falls onto the stacking plate 53 is folded. The material stacked on top falls onto a portion of the belt conveyor 52. Then, the linear module 51 drives the belt conveyor 52 to move vertically downward, so that each subsequent square piece of fabric falls at the same height. The dual-worker displacement mechanism 4 alternately places the material on two stacking plates 53, repeating the above operation, thereby making adjacent square pieces of fabric fold and connect with each other. When the number of stacked square pieces of fabric reaches a set number, the belt conveyor 52 drives the square pieces of fabric to move to the bottom of the pressure plate 55 and drives the square pieces of fabric to move vertically upward. With the cooperation of the pressure plate 55, the stacked material is compacted, and finally the material is unloaded by the operator.

[0049] In this invention, the square fabric pieces are alternately placed on two stacking plates 53 by the dual-worker material transfer mechanism 4, and the adjacent square fabric pieces are folded together by the cooperation of the linear module 51 and the flipping component 56. Finally, the pressure plate 55 is used to press them down, realizing the automatic material handling process of the finished parts, which greatly improves the production efficiency. The stacked finished parts are tightly connected, which is not only neat and beautiful, but also easy to pack.

[0050] Example 2

[0051] like Figure 3 , 5As shown in Figure 6, in a preferred embodiment of the present invention, the fabric cutting mechanism 3 includes a processing table 31, a cross-cutting device 32, a cross groove 33, an ultrasonic generator 34, a first fastening assembly 35, a second fastening assembly 36, and a tilting cylinder 37. The processing table 31 is fixedly installed on one end of the second support frame 102 near the first support frame 101 and is inclined. The cross-cutting device 32 is fixedly installed on the second support frame 102 and is mounted on the upper side of the processing table 31. A cross groove 33 for the movement of the ultrasonic generator 34 is provided on the processing table 31. The tilting cylinder 37 is fixedly installed on the lower side of the second support frame 102, and the output end of the tilting cylinder 37 is fixedly connected to the ultrasonic generator 34. The first fastening assembly 35 is installed on the second conveyor belt 204, and the second fastening assembly 36 is installed on the second support frame 102.

[0052] The first fastening assembly 35 includes a first adjusting cylinder 351, a mounting bracket 352, a horizontal shaft 353, and pressure blocks 354. Two first adjusting cylinders 351 are symmetrically fixedly installed on both sides of the second conveyor belt 204. The output end of the first adjusting cylinder 351 is fixedly installed with the mounting bracket 352, and the horizontal shaft 353 is fixedly installed between the mounting brackets 352. Multiple pressure blocks 354 are evenly fixedly installed on the horizontal shaft 353 at equal intervals.

[0053] The second fastening assembly 36 includes a bracket 361, a fixed pressure roller 362, a movable pressure roller 363, an adjusting block 364, an adjusting groove 365, and a second adjusting cylinder 366. The two brackets 361 are symmetrically fixedly installed on both sides of the second support frame 102. The bracket 361 has an adjusting groove 365 that is slidably connected to the adjusting block 364. The second adjusting cylinder 366 is fixedly installed on the top of the bracket 361, and the output end of the second adjusting cylinder 366 is fixedly connected to the adjusting block 364. The fixed pressure roller 362 is rotatably installed between the brackets 361 through bearings, and the movable pressure roller 363 is rotatably installed between the adjusting blocks 364 through bearings.

[0054] In this invention, after passing through the guide roller 201, the material passes between the processing table 31 and the cross-cutting device 32 and falls onto the first conveyor belt 203. The first adjusting cylinder 351 moves the horizontal shaft 353 closer to the first conveyor belt 203 until the pressure block 354 presses the material onto the first conveyor belt 203. Simultaneously, the second adjusting cylinder 366 drives the adjusting block 364 to move vertically downwards within the adjusting groove 365, causing the movable pressure roller 363 to approach the fixed pressure roller 362 and clamp the material. This ensures that the portions of the material located on both sides of the cross-cutting device 32 are simultaneously clamped. Then, the tilting cylinder 37 drives the ultrasonic generator. The cutter 34 extends from the transverse groove 33. The cutter of the transverse cutting device 32 and the ultrasonic generator 34 work together to cut the material into square cloth pieces. After the cutting is completed, the pistons of the first adjusting cylinder 351 and the second adjusting cylinder 366 are reset to release the material. The tilting cylinder 37 drives the ultrasonic generator 34 to reset, so that the first conveyor belt 203 can smoothly transport the square cloth pieces. Through the cooperation of the pressure block 354, the fixed pressure roller 362 and the movable pressure roller 363, the material is clamped on both sides of the cutting part at the same time, so that the material will not be displaced during the cutting process, ensuring the accuracy of material cutting.

[0055] Example 3

[0056] like Figure 7 As shown, in a preferred embodiment of the present invention, the dual-workstation material transfer mechanism 4 includes a crossbar 41, a slide bar 42, a belt linear module 43, a slide table 44, a material transfer cylinder 45, and a support 46. The crossbar 41 is fixedly installed on the first support frame 101, and the slide bar 42 is fixedly installed on the crossbar 41. A set of belt linear modules 43 is fixedly installed on each of the front and rear sides of the crossbar 41. The two slide tables 44 are symmetrically arranged and slidably connected to the slide bar 42. The two slide tables 44 are respectively fixedly connected to the moving ends of the two belt linear modules 43. The material transfer cylinder 45 is fixedly installed on the slide table 44, and the support 46 is fixedly installed on the output end of the material transfer cylinder 45. Multiple pneumatic grippers 47 for clamping square fabric pieces are fixedly installed on the support 46.

[0057] In this invention, the belt linear module 43 drives two slide tables 44 to move synchronously in opposite directions under the limiting action of the slide rod 42. When the finished part reaches the set position, the material transfer cylinder 45 drives the flipping component 56 to move vertically downward, and the square cloth piece is clamped by the pneumatic gripper 47 and moved to the belt conveyor line 52 on both sides for release. By controlling the synchronous movement of the two sets of pneumatic grippers 47 through the belt linear module 43, the synchronous material transfer function of the two sets of finished parts on the first support frame 101 is realized, which greatly improves the material transfer speed and thus increases the production efficiency.

[0058] Example 4

[0059] like Figure 8As shown, in a preferred embodiment of the present invention, the flipping assembly 56 includes a bracket 561, a stacking cylinder 562, a first connecting rod 563, and a second connecting rod 564. The bracket 561 is fixedly mounted on the first support frame 101. The stacking plate 53 is hinged to the top of the bracket 561. The first connecting rod 563 is configured as a near-V shape. One end of the first connecting rod 563 is hinged to the bracket 561, and the other end of the first connecting rod 563 is fixedly connected to the second connecting rod 564. The other end of the second connecting rod 564 is hinged to the stacking plate 53. The lower end of the stacking cylinder 562 is hinged to the first support frame 101, and the output end of the stacking cylinder 562 is hinged to the corner of the first connecting rod 563. The piston extension of the stacking cylinder 562 pushes the first connecting rod 563 and the second connecting rod 564 to rotate, thereby driving the stacking plate 53 to rotate, realizing the folding operation of the finished product. The piston reset of the stacking cylinder 562 can reset the stacking plate 53.

[0060] Example 5

[0061] like Figure 1-9 As shown, in a preferred embodiment of the present invention, a method for an ultrasonic oblique-cutting and extracting square fabric folding machine is also provided, comprising the following steps:

[0062] Step 1: The material is connected to the guide roller 201 in a wave-like manner and separated into two strips by the dividing ring 202. Then it passes between the processing table 31 and the cross-cutting device 32 and falls onto the first conveyor belt 203.

[0063] Step 2: The first adjusting cylinder 351 moves the horizontal shaft 353 closer to the first conveyor belt 203 until the pressing block 354 presses the material onto the first conveyor belt 203. At the same time, the second adjusting cylinder 366 drives the adjusting block 364 to move vertically downward in the adjusting groove 365, so that the movable pressing roller 363 approaches the fixed pressing roller 362 to clamp the material, so that the parts of the material located on both sides of the cross-cutting device 32 are clamped at the same time.

[0064] Step 3: The tilting cylinder 37 drives the ultrasonic generator 34 to extend from the transverse groove 33. The cutter of the transverse cutting device 32 and the ultrasonic generator 34 work together to cut the material into square cloth pieces. After the cutting is completed, the pistons of the first adjusting cylinder 351 and the second adjusting cylinder 366 are reset to release the material. The tilting cylinder 37 drives the ultrasonic generator 34 to reset. Then, the square cloth pieces are conveyed through the first conveyor belt 203 and the second conveyor belt 204.

[0065] Step 4: After the square fabric pieces are moved to the set position, the double-worker shifting mechanism 4 moves the two sets of square fabric pieces to the two side sorting mechanisms 5 respectively. In the sorting mechanism 5 on one side, half of the square fabric piece falls on the belt conveyor 52, and the other half of the square fabric piece falls on the left stacking plate 53. Then, the double-worker shifting mechanism 4 grabs a new square fabric piece and releases it. At this time, half of the new square fabric piece falls on the belt conveyor 52, and the other half of the square fabric piece falls on the right stacking plate 53. The flipping component 56 is activated to drive the left stacking plate 53 to flip, so that the part of the second-top square fabric piece that falls on the stacking plate 53 is folded on the part of the top material that falls on the belt conveyor 52. Then, the linear module 51 drives the belt conveyor 52 to move vertically downward, so that each subsequent square fabric piece falls at the same height. The double-worker shifting mechanism 4 alternately places the material on the two stacking plates 53 and repeats the above operation to make adjacent square fabric pieces fold and connect with each other.

[0066] Step 5: When the number of stacked square fabric pieces reaches the set number, the belt conveyor 52 moves the square fabric pieces to the bottom of the pressure plate 55 and moves them vertically upward. With the cooperation of the pressure plate 55, the stacked material is compacted, and finally the operator unloads the material.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.

6. A method for an ultrasonic oblique-cutting extraction type square fabric folding integrated machine as described in claim 5, characterized in that, Includes the following steps: Step 1: The material is connected to the guide roller (201) in a wave-like manner and separated into two strips by the dividing ring (202). Then it passes between the processing table (31) and the cross-cutting device (32) and falls onto the first conveyor belt (203); Step 2: The first adjusting cylinder (351) moves the horizontal shaft (353) closer to the first conveyor belt (203) until the pressure block (354) presses the material onto the first conveyor belt (203). At the same time, the second adjusting cylinder (366) drives the adjusting block (364) to move vertically downward in the adjusting groove (365), so that the movable pressure roller (363) moves closer to the fixed pressure roller (362) to clamp the material, so that the parts of the material located on both sides of the cross-cutting device (32) are clamped at the same time. Step 3: The tilting cylinder (37) drives the ultrasonic generator (34) to extend out from the transverse groove (33). The cutter of the transverse cutting device (32) and the ultrasonic generator (34) work together to cut the material into square cloth pieces. After the cutting is completed, the pistons of the first adjusting cylinder (351) and the second adjusting cylinder (366) are reset to release the material. The tilting cylinder (37) drives the ultrasonic generator (34) to reset. Then the square cloth pieces are conveyed through the first conveyor belt (203) and the second conveyor belt (204). Step 4: After the square fabric pieces are moved to the set position, the double-worker shifting mechanism (4) moves the two sets of square fabric pieces to the two side sorting mechanisms (5) respectively; in the sorting mechanism (5) on one side, half of the square fabric piece falls on the belt conveyor (52), and the other half of the square fabric piece falls on the stacking plate (53) on the left side. Then the double-worker shifting mechanism (4) grabs the new square fabric piece and releases it. At this time, half of the new square fabric piece falls on the belt conveyor (52), and the other half of the square fabric piece falls on the stacking plate (53) on the right side. 3) Start the flipping component (56) to flip the stacking plate (53) on the left side, so that the part of the second top square cloth piece that falls on the stacking plate (53) is folded on the part of the top material that falls on the belt conveyor (52). Then the linear module (51) drives the belt conveyor (52) to move vertically downward, so that each square cloth piece falls at the same height. The double-worker displacement mechanism (4) alternately places the material on the two stacking plates (53) and repeats the above operation to make the adjacent square cloth pieces fold and connect with each other. Step 5: When the number of stacked square fabric pieces reaches the set number, the belt conveyor (52) moves the square fabric pieces to the bottom of the pressure plate (55) and moves the square fabric pieces vertically upward. With the cooperation of the pressure plate (55), the stacked materials are compacted, and finally the materials are unloaded by the operator.
