Description

Technical Field

[0001] This invention relates to the field of shoe upper manufacturing technology, and more specifically, to a high-precision continuous shoe upper manufacturing production line and process. Background Technology

[0002] Most shoes consist of an upper and a sole, with the upper fixed to the sole. A space is formed between the upper and sole for the foot to slip on. Traditional uppers are single-layered with limited functionality. To improve functionality, current uppers are mostly composite structures, i.e., double-layered fabrics. In manufacturing composite uppers, the two layers are first glued together before cutting. This process wastes glue between the cut fabrics, leading to resource waste and increased costs. It is not conducive to large-scale production and cannot meet user needs. Given these shortcomings, further improvements are necessary to enhance practicality and suit real-world applications.

[0008] Furthermore, the two clamping mechanisms are symmetrically arranged about the horizontal plate, and each clamping mechanism includes a first vertical plate. A first threaded rod and a first guide rod pass through the first vertical plate. The first vertical plate and the first threaded rod are threaded together, and the first vertical plate is attached to the first guide rod but not fixed. A first through groove is provided on the first vertical plate, and a hydraulic cylinder is bolted to the groove wall. The piston rod end of the hydraulic cylinder is welded to the top surface of the lifting plate, and the bottom surface of the lifting plate is welded with connecting columns that are evenly distributed. The bottom end of the connecting columns passes through the wall of the first vertical plate and is welded with a pressure plate. The cross-section of the pressure plate and the cutting plate is consistent with the shape and size of the adhesive groove, and the bottom surface of the side wall of the cutting plate is blade-shaped.

[0009] Furthermore, the fixing cylinder is a hollow cylinder, and the number of fixing cylinders and the second connecting pipes are the same and correspond one-to-one. The inner wall of the fixing cylinder is seamlessly attached to the outer circular wall of the fixing ring, and the fixing ring, the first movable column, the fixing column and the slot are all coaxial. The outer wall of the fixing column and the inner wall of the slot are seamlessly attached, and the slot penetrates the first movable column.

[0010] Furthermore, the adhesive grooves are arranged in a rectangular array on the horizontal plate, and the cross-section of the groove wall is arc-shaped.

[0011] Furthermore, the communicating vessel includes a communicating cylinder, which is welded and connected to both the first and second guiding tubes. A sealing piston is provided inside the communicating cylinder, and a limit ring is welded to the inner wall of the communicating cylinder. The center of the top surface of the sealing piston is welded to the bottom end of the second movable column, and the top end of the second movable column extends from the top of the communicating cylinder and is welded to a top plate.

[0016] A high-precision continuous shoe upper manufacturing process.

[0017] Includes the following steps:

[0018] 1. Place the shoe upper fabric rolls onto the rotating rollers in one of the fixed frames, and then wrap one end of the shoe upper fabric rolls around and fix it onto the rotating rollers in the other fixed frame. At the same time, use the tension rollers to keep the shoe upper fabric in a taut state and make it fit against the front and back of the horizontal board.

[0019] 2. Connect the glue inlet tube to the external glue supply equipment, and simultaneously drive the clamping mechanism and the second vertical plate to move horizontally. When the clamping mechanism moves, the glue can be injected into the bonding tank.

[0020] 3. The pressure plates in the two pressing mechanisms move towards each other and extend into the adhesive groove, thereby pressing and bonding the fabric on both sides of the horizontal plate together.

[0021] Fourth, the cutting plate on the second vertical plate goes down and passes through the adhesive groove, which can cut off the fabric that is bonded in the adhesive groove.

[0022] 5. After all the fabric on the horizontal plate has been punched, the rotating roller in the fixed frame will rotate, so that the fabric can continue to be conveyed for bonding and cutting operations.

[0023] The advantages of the high-precision continuous shoe upper manufacturing production line and process of the present invention are as follows:

[0024] The invention consists of a horizontal plate with multiple adhesive grooves. The adhesive grooves are the same shape and size as the shoe upper. During the bonding process, the two fabrics are respectively attached to the front and back of the horizontal plate.

[0025] It is equipped with two sets of symmetrically distributed pressing mechanisms. When the pressing mechanism moves horizontally, it automatically controls the glue to be sprayed from the bonding groove opposite the pressing mechanism. In this way, when the pressing mechanism presses the fabric on both sides of the horizontal plate, it can press the two layers of fabric into the bonding groove and press and bond the two layers of fabric into one piece in the bonding groove. In the entire bonding process, the glue is sprayed only at fixed points and timed times, which avoids glue waste, saves resources and reduces costs, and is conducive to large-scale production and use.

[0026] A second vertical plate is provided, which can move synchronously with the pressing mechanism. When the pressing mechanism is pressing and bonding the two layers of fabric, the cutting plate on the second vertical plate can punch and cut the bonded fabric, thereby realizing simultaneous bonding and cutting, which greatly improves work efficiency.

[0027] The pressure plate, cutting plate and bonding groove are the same shape and size, so that when bonding and punching the fabric, the upper can be cut to the specified size. The overall processing accuracy is high and the pass rate of upper manufacturing is improved.

[0028] Meanwhile, the upper material is fixed on two rotating rollers. The rotation of the rollers can drive the material to move horizontally on the horizontal plate, thus enabling continuous bonding and cutting operations, thereby further improving work efficiency. Attached Figure Description

[0041] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0043] Please see Figure 1-10 This invention provides a technical solution: a high-precision continuous shoe upper manufacturing production line, including two supports 1 and a horizontal plate 2 welded and fixed to the supports 1. A first fixed plate 6 and a second fixed plate 7 are welded and connected to both supports 1, and a fixed frame 3 is provided on one side of each of the two supports 1. A set of rotating rollers 4 and a set of tensioning rollers 5 are connected to the fixed frame 3. Before production, two rolls of fabric are fixed to the rotating roller 4 in one of the fixed frames 3, and one end of the fabric is pulled and wound and fixed to the rotating roller 4 in the other fixed frame 3. At the same time, the tensioning rollers 5 keep the fabric in a tensioned state, so that the fabric can adhere to both sides of the horizontal plate 2. At the same time, the rotation of the tensioning rollers 5 can drive the fabric to move continuously on the surface of the horizontal plate 2, thereby realizing continuous operation and high work efficiency.

[0044] An adhesive groove 26 is provided on the horizontal plate 2, and a first glue inlet groove 201 and a second glue inlet groove 202 are provided in the wall of the horizontal plate 2. A first glue guide tube 27 is inserted into one end of the first glue inlet groove 201, and the first glue guide tube 27 is connected to the second glue guide tube 28 through a communicating vessel 29. One end of the second glue inlet groove 202 is connected to the first glue inlet groove 201, and the other end of the second glue inlet groove 202 is connected to the wall of the adhesive groove 26. The second glue guide tube 28 is welded and connected to the connecting post 36, and one end of the connecting post 36 is welded and connected to the glue inlet tube 37. The connecting post 36 has a hollow rectangular column structure, and the second glue guide tube 28, the first glue inlet groove 201 and the first glue guide tube 27 on it are all distributed at equal intervals.

[0045] The communicating vessel 29 includes a communicating cylinder 291, which is welded and connected to both the first adhesive guide tube 27 and the second adhesive guide tube 28. A sealing piston 292 is installed inside the communicating cylinder 291, and a limit ring 294 is welded to the inner wall of the communicating cylinder 291. The center of the top surface of the sealing piston 292 is welded to the bottom end of the second movable column 293. The top end of the second movable column 293 extends from the top of the communicating cylinder 291 and is welded to a top plate 296. A second elastic spring 295 is fitted onto the second movable column 293 between the top plate 296 and the top of the communicating cylinder 291. The protrusion 31 is cylindrical, and a first magnet is embedded in the bottom surface of the protrusion 31. A second magnet is embedded in the top surface of the top plate 296, and the opposite sides of the second magnet and the first magnet have the same magnetic poles. The adhesive inlet tube 37 is connected to an external adhesive supply device. Thus, when… The protrusion 31 moves horizontally onto the top plate 296, and the second magnet and the first magnet generate a repulsive force, which in turn pushes the top plate 296 to move vertically downward. The top plate 296 drives the sealing piston 292 downward through the second movable column 293, so that the sealing piston 292 is in contact with the bottom of the connecting cylinder 291, thereby exposing the connection between the first adhesive guide tube 27 and the second adhesive guide tube 28 and the connecting cylinder 291. The first adhesive guide tube 27 is in a connected state through the connecting cylinder 291 and the second adhesive guide tube 28, so that the adhesive enters the connecting column 36 through the adhesive inlet tube 37, and enters the first adhesive guide tube 27 through the second adhesive guide tube 28 and the connecting cylinder 291. Finally, the adhesive enters the first adhesive inlet groove 201 and is sprayed into the adhesive groove 26 through the second adhesive inlet groove 202, so that the adhesive can fall onto the fabric surface that is in contact with the bottom surface of the horizontal plate 2.

[0046] Two first fixed plates 6 are welded together by a first guide rod 10, and a first threaded rod 8 is passed through the two first fixed plates 6 and is movably connected to its bearing. The first threaded rod 8 is keyed to the output shaft of the forward and reverse motor 12. Two second fixed plates 7 are welded together by a second guide rod 11, and a second threaded rod 9 is passed through the two second fixed plates 7 and is movably connected to its bearing. Mounting brackets 32 are welded to both the second fixed plates 7 and the first fixed plates 6. A clamping mechanism 13 is provided on both the first threaded rod 8 and the second threaded rod 9. A side plate 30 is welded to one side of the clamping mechanism 13 on the first threaded rod 8, and a protrusion 31 is formed by the bottom surface of the side plate 30 extending vertically downward. The first threaded rod 8 and the first guide rod 10 pass through the second vertical plate 14. The forward and reverse motor 12 is bolted to the first fixed plate 6.

[0047] Two clamping mechanisms 13 are symmetrically arranged about the horizontal plate 2. Each clamping mechanism 13 includes a first vertical plate 131, through which a first threaded rod 8 and a first guide rod 10 pass. The first vertical plate 131 and the first threaded rod 8 are threaded together, while the first guide rod 10 is attached to the first vertical plate 131 but not fixed. A first through groove 132 is provided on the first vertical plate 131, and a hydraulic cylinder 133 is bolted to the groove wall of the first through groove 132. The piston rod end of the hydraulic cylinder 133 is welded to the top surface of the lifting plate 134, and the bottom surface of the lifting plate 134 is welded with connecting columns 135 distributed at equal intervals. The bottom end of the connecting columns 135 passes through the wall of the first vertical plate 131 and is welded to... The pressure plate 136 has two shafts welded to each of the two mounting brackets 32, and each shaft is secured with a first sprocket 33 by a pin. A second sprocket 34 is secured to one end of each of the first threaded rod 8 and the second threaded rod 9. A meshing transmission chain 35 is fitted onto the second sprocket 34 on both shafts and the first sprocket 33 on the two mounting brackets 32. When the forward and reverse motor 12 operates, it drives the first threaded rod 8 to rotate axially between the two first fixed plates 6. This causes the first threaded rod 8 to drive the first vertical plate 131 on it to move horizontally along the first guide rod 10. Simultaneously, when the first threaded rod 8 rotates, it drives the transmission chain 35 via the second sprocket 34. As the drive chain 35 rotates, the second sprocket 34 on the second threaded rod 9 drives the second threaded rod 9 to rotate axially between the two second fixed plates 7. This allows the second threaded rod 9 to move the first vertical plate 131 along the second guide rod 11, enabling the two first vertical plates 131 to move synchronously. When the first vertical plate 131 on the first threaded rod 8 moves, the side plate 30 drives the protrusion 31 to move horizontally. When the protrusion 31 moves to be vertically aligned with the top plate 296, adhesive is automatically sprayed into the adhesive groove 26 opposite to the pressure plate 136. Adhesive is not sprayed into the other adhesive grooves 26, thus preventing premature spraying of adhesive. Solidification occurs, ensuring the bonding effect between the fabrics. At the same time, the fabrics around the adhesive groove 26 are not sprayed with adhesive, thus avoiding adhesive waste. After the adhesive is sprayed, the hydraulic cylinders 133 on the two first vertical plates 131 move synchronously. The hydraulic cylinders 133 can push the lifting plate 134 to move within the first through groove 132. The lifting plate 134 can push the pressure plate 136 to move through the connecting column 135. In this way, the pressure plate 136 on the two first vertical plates 131 can extend into the adhesive groove 26, pressing the fabrics on both sides of the horizontal plate 2 into the adhesive groove 26 and pressing and bonding the two layers of fabrics tightly. After pressing and bonding, the hydraulic cylinder 133 drives the pressure plate 136 to reset.

[0048] The second vertical plate 14 is threadedly connected to the first threaded rod 8, and is attached to but not fixed to the first guide rod 10. A second through groove 15 is provided on the second vertical plate 14, and an air pump 16 is bolted to the top wall of the second vertical plate 14. A fixing cylinder 17 is welded to the groove wall of the second through groove 15, and a fixing ring 18 is provided inside the fixing cylinder 17. The air outlet of the air pump 16 is threadedly sealed to one end of the first connecting pipe 24, and the other end of the first connecting pipe 24 is closed and welded to and connected to the second connecting pipe 25. A fixing post is welded to the inner wall of the top of the fixing cylinder 17. 20, and a first movable column 19 is passed through the bottom wall of the fixed cylinder 17. The first movable column 19 has a slot 22 for inserting the fixed column 20. The bottom end of the first movable column 19 passes through the wall of the second vertical plate 14 and the bottom end of the first movable column 19 passes through the wall of the cutting plate 23 and is welded to the cutting plate 23. The inner wall of the fixed ring 18 is welded to the outer wall of the first movable column 19. A first elastic spring 21 is sleeved on the first movable column 19 between the fixed ring 18 and the bottom end of the fixed cylinder 17. The second connecting pipe 25 is welded to and connected to the wall of the fixed cylinder 17. The first threaded rod When the axial rotation is performed, the second vertical plate 14 can be moved horizontally along the first guide rod 10. When the second vertical plate 14 moves above the bonded fabric, the air pump 16 starts to work. The air pump 16 injects air into each fixed cylinder 17 through the first connecting pipe 24 and the second connecting pipe 25. This increases the air pressure in the fixed cylinder 17, which can push the fixed ring 18 and the first movable column 19 downward within the fixed cylinder 17. The first movable column 19 drives the cutting plate 23 to move downward synchronously. When the cutting plate 23 moves into the bonding groove 26, the bonded fabric in the bonding groove 26 can be processed. During the punching operation, the first movable column 19 can move along the fixed column 20 through the slot 22. Before the punching operation is completed, the fixed column 20 will not move out of the slot 22. After the punching operation is completed, the fixed column 20 will move out of the slot 22. In this way, the air in the fixed cylinder 17 will be ejected from the slot 22. Then, when the cutting plate 23 punches and the fabric is stuck in the cutting plate 23, the air ejected from the slot 22 will blow the fabric out of the cutting plate 23. This can prevent too much fabric from getting stuck in the cutting plate 23 and ensure that the cutting operation is carried out normally and stably.

[0049] Furthermore, the cross-sections of the pressure plate 136 and the cutting plate 23 are consistent with the shape and size of the bonding groove 26, and the bottom side wall of the cutting plate 23 is blade-shaped. The structural design of the pressure plate 136 and the cutting plate 23 allows the two pressure plates 136 to press the fabric into the bonding groove 26, which can press the fabric tightly and bond it into the shape of the shoe upper. At the same time, after the cutting plate 23 moves down, it can cut off the pressed and bonded fabric. The cut fabric is the shoe upper to be manufactured. The overall manufacturing process is highly precise and helps to improve the overall processing quality.

[0050] Furthermore, the fixing cylinder 17 is a hollow cylinder, and the number of fixing cylinders 17 and the second connecting pipes 25 are the same and correspond one-to-one. The inner wall of the fixing cylinder 17 fits seamlessly with the outer circular wall of the fixing ring 18. The fixing ring 18, the first movable column 19, the fixing column 20, and the slot 22 are all coaxial. The outer wall of the fixing column 20 fits seamlessly with the inner wall of the slot 22, and the slot 22 penetrates the first movable column 19. When the fixing column 20 is inserted into the slot 22 in the first movable column 19, the top surface of the first movable column 19 and the fixing ring 18 cooperate with the inner wall of the fixing cylinder 17 to form a sealed cavity. When the air pump 16 injects air into the cavity, the air pressure will push the first movable column 19 and the fixing ring 18 downward. When the air pump 16 starts to depressurize and exhaust air, under the action of the elastic force of the first elastic spring 21, the first movable column 19 can be driven to return to its original position through the fixing ring 18. In this way, the first movable column 19 can drive the cutting plate 23 to move vertically back and forth, so as to continuously cut the fabric.

[0051] Furthermore, the adhesive grooves 26 are arranged in a rectangular array on the horizontal plate 2, and the cross-section of the groove wall of the adhesive groove 26 is arc-shaped. The groove wall structure design of the adhesive groove 26 reduces the friction between the fabric and the groove wall of the adhesive groove 26 when the two pressure plates 136 press the fabric into the adhesive groove 26, avoids the fabric from being worn and broken, and thus ensures that the subsequent cutting operation can proceed normally.

[0052] Furthermore, the sealing piston 292 fits seamlessly with the inner wall of the connecting cylinder 291, and the thickness of the sealing piston 292 is greater than the diameter of the first guide tube 27 and the second guide tube 28. The first guide tube 27 and the second guide tube 28 are coaxial, and the first guide tube 27 is sealed and bonded to the groove wall of the first glue inlet groove 201. When the top plate 296 is aligned with the protrusion 31, the second elastic spring 295 is in its natural state, and the sealing piston 292 abuts against the limiting ring 294 through the second movable column 293. In this way, the sealing piston 292 can block the connection between the first guide tube 27 and the second guide tube 28 and the connecting cylinder 291, thereby making the first guide tube 27 and the second guide tube 28 in an open circuit state, preventing the glue from passing through. The structure is reasonable.

[0053] A high-precision continuous shoe upper manufacturing process.

[0054] Includes the following steps:

[0055] 1. Place the shoe upper fabric rolls onto the rotating rollers 4 in one of the fixed frames 3, and wrap one end of the shoe upper fabric rolls around and fix them onto the rotating rollers 4 in the other fixed frame 3. At the same time, use the tension rollers 5 to keep the shoe upper fabric in a taut state and to make it fit against the front and back of the horizontal plate 2.

[0056] 2. Connect the glue inlet tube 37 to an external glue supply device, and simultaneously drive the clamping mechanism 13 and the second vertical plate 14 to move horizontally. When the clamping mechanism 13 moves, the glue can be injected into the adhesive tank 26.

[0057] Third, the pressure plates 136 in the two pressing mechanisms 13 move towards each other and extend into the adhesive groove 26, thereby pressing and bonding the fabric on the front and back of the horizontal plate 2 into one piece.

[0058] Fourth, the cutting plate 23 on the second vertical plate 14 moves down and passes through the adhesive groove 26, so that the fabric bonded in the adhesive groove 26 can be cut off.

[0059] 5. After all the fabric on the horizontal plate 2 has been punched, the rotating roller 4 in the fixed frame 3 will rotate, so that the fabric can continue to be conveyed for bonding and cutting operations.
