Description

Technical Field

[0001] This invention relates to the field of shoe upper flattening technology, and in particular to a shoe upper flattening device and flattening process for combat boots, training shoes, and everyday leather shoes. Background Technology

[0002] In the shoe manufacturing process, the flatness of the upper is a key factor in determining the final quality of the shoe. It not only directly affects the aesthetic appearance of the shoe, but is also closely related to the comfort when wearing it. For special and important footwear such as combat boots, training shoes, and dress shoes, the importance of the upper flattening process is further highlighted due to the diversity of their usage scenarios and the special requirements of wearing them. Combat boots need to have good protective performance and durability, training shoes emphasize lightness, flexibility and support, and dress shoes focus on the exquisite and elegant appearance. The realization of these characteristics is inseparable from high-quality upper flattening treatment.

[0003] However, current shoe upper flattening technology faces a significant challenge in processing shoe upper materials: it struggles to effectively unfold the wrinkles. During the flattening process, existing equipment often lacks a comprehensive and meticulous mechanism for unfolding the material, making it difficult to completely eliminate wrinkles. Even after flattening, shoe upper materials often retain some wrinkles, which not only disrupt the overall smoothness of the upper, making the shoes look less aesthetically pleasing and less refined, thus affecting market competitiveness, but may also cause discomfort to the feet during wear, reducing comfort and even impacting the shoe's lifespan and performance. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing equipment often lacks an effective mechanism for fully and meticulously unfolding materials during the flattening process, making it difficult to completely eliminate wrinkles. Even after flattening, shoe upper materials still retain some wrinkles, which not only disrupt the overall flatness of the shoe upper, making the shoes look less aesthetically pleasing and refined, thus affecting the product's market competitiveness, but may also cause discomfort to the feet during wear, reduce wearing comfort, and even affect the lifespan and performance of the shoes. Therefore, this invention proposes a solution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flattening device for the upper of combat boots, training shoes, and regular leather shoes: including a frame, the frame including a base and a support frame, and further including: a flattening component and an adjusting component assembled on the top of the base;

[0006] The flattening assembly includes a fixed plate fixedly connected to one side of the support frame, and two connecting frames fixedly connected to the top of the base. A driving component is installed on one side of the fixed plate, and a connecting plate is fixedly connected to the bottom of the driving component. Two positioning rods are fixedly connected to both sides of the connecting plate. A limit plate is fixedly connected to one side of the positioning rod. Two symmetrical vertical grooves and a first moving groove communicating with the vertical grooves are opened inside the two connecting frames. A moving block is slidably connected to the inner wall of the vertical groove. A moving rod is installed inside the moving block. A limit block is fixedly connected to the side of the moving rod, and the moving rod and the positioning rod are connected by a connecting sleeve rod. The moving rod is connected to a sleeve plate through an outer adjustment component. An elastic element is connected to the bottom of the sleeve plate.

[0007] The driving component abuts against the connecting sleeve rod, causing the moving block to move within the vertical groove and the elastic component to press down on the material. As the driving component continues to descend, it abuts against the moving block to move within the first moving groove, causing the elastic component to push the material laterally and reduce wrinkles.

[0008] As a further description of the above technical solution:

[0009] The elastic element includes several inner cavities opened at the bottom of the sleeve plate. Each inner cavity has a telescopic column slidably connected to its inner wall. A telescopic spring is connected between the telescopic column and the inner cavity. The bottom of the telescopic column is connected to the pressure plate. The outer periphery of the sleeve plate is chamfered.

[0010] As a further description of the above technical solution:

[0011] Each of the moving blocks has an inner groove on one side, and a pressure spring is installed on the inner wall of each inner groove.

[0012] As a further description of the above technical solution:

[0013] Both of the connecting frames have transverse grooves and clearance grooves inside. The inner wall of the clearance groove is threaded with a threaded rod, and one end of the threaded rod passes through the clearance groove and connects to the pressure block.

[0014] As a further description of the above technical solution:

[0015] The driving component includes a hydraulic cylinder mounted on one side of the fixed plate, and a hydraulic rod is connected between the bottom of the hydraulic cylinder and the connecting plate.

[0016] As a further description of the above technical solution:

[0017] The adjustment assembly includes a second movable groove inside the connecting frame, and a groove and a slot on the outer periphery of the movable rod. The outer periphery of the groove is rotatably connected to the sleeve plate through a rotating sleeve plate, and the slot and the rotating sleeve plate are connected through a one-way component.

[0018] As a further description of the above technical solution:

[0019] The one-way component includes several snap-fit ​​blocks fixedly connected to the outer periphery of the slot, a fixing frame fixedly connected to the inner wall of the rotating sleeve, and a central column connected to the inner wall of the fixing frame. An abutment block that contacts the snap-fit ​​blocks is rotatably connected to the outer periphery of the central column, and a limiting block and a spring sheet that contact the abutment block are fixedly connected to the inner wall of the rotating sleeve.

[0020] As a further description of the above technical solution:

[0021] A fixing assembly is installed on the outer periphery of the movable rod. The fixing assembly includes a fixing collar fixedly connected to the outer periphery of the movable rod. Several extension rods are fixedly connected to one side of the fixing collar. One side of each extension rod is connected to the top ring. A movable collar is slidably connected to the outer periphery of the extension rod. A compression spring is sleeved on the outer periphery of each extension rod. A limiting groove is opened on the outer periphery of both the movable rod and the rotating sleeve plate. Several limiting plates that contact the limiting groove are fixedly connected to the inner wall of the movable collar.

[0022] As a further description of the above technical solution:

[0023] A process for flattening the uppers of combat boots, training shoes, and service leather shoes includes the following steps:

[0024] S01: Lay the flat material to be pressed flat on the base, with the edge of the fabric as close to the horizontal groove as possible. Manually turn the threaded rod to lower it, which will cause the pressure block to descend. The pressure block will contact the fabric and apply pressure to complete the fixing and prevent the fabric from shifting during subsequent pressing.

[0025] S02: Start the hydraulic cylinder, which drives the hydraulic rod, connecting plate and positioning rods on both sides to descend. The positioning rod abuts against the connecting sleeve rod, pushing the moving rod to make the moving block slide down the vertical groove. The sleeve plate approaches the fabric. After the pressure plate contacts the fabric, it generates a reaction force according to the fabric thickness, pushing the telescopic column to squeeze the telescopic spring. It adapts to different fabric thicknesses and flattens the fabric. When the moving block slides to the bottom of the vertical groove, the pressure spring pushes it into the first moving groove. The connecting plate continues to descend, driving the moving block to move laterally in the first moving groove. The sleeve plate and pressure plate move laterally to unfold the fabric folds.

[0026] S03: After initial flattening, the hydraulic cylinder is restarted to raise the hydraulic rod. The connecting plate rises and pulls the positioning rod and connecting sleeve rod. The moving block moves along the first moving groove to approach the vertical groove and enters it. When it moves to the top of the vertical groove, the pressure spring pushes it into the second moving groove. Then, the hydraulic cylinder is restarted to lower the hydraulic rod. The connecting plate falls and pushes the positioning rod and connecting sleeve rod, causing the moving block to move in the second moving groove. This drives the two sleeve plates away from each other to prevent subsequent rotation operations from interfering with each other.

[0027] S04: Manually rotate the rotating sleeve plate to drive the sleeve plate and internal fixing frame to rotate. The abutment block on the outer periphery of the center column rotates. When the abutment block contacts the locking block, the locking block abuts its rotation and squeezes the spring sheet. After the contact is broken, the spring sheet pushes it to reset and contacts the limiting block. After adjusting the tilt angle of the chamfer on the side of the sleeve plate close to the fabric, proceed to the next operation.

[0028] S05: Start the hydraulic cylinder to raise the hydraulic rod, the connecting plate rises and pushes the positioning rod and connecting sleeve rod, which drives the moving rod to move the moving block in the second moving groove. The two sleeve plates approach each other in a V shape. Start the hydraulic cylinder again to lower the hydraulic rod, the connecting plate falls and pushes the positioning rod and connecting sleeve rod, which drives the moving rod to move the moving block in the second moving groove. The two sleeve plates move away from each other. The chamfering pulls the fabric surface to reduce wrinkles and adjusts the tilt angle to adapt to fabrics of different thicknesses.

[0029] S06: When the sleeve is pushed to both sides, the abutment block and the locking block on the inner wall of the rotating sleeve abut against each other to prevent deflection. When adjusting the angle, manually push the moving collar to slide on the outer circumference of the extension rod, which will drive the limiting plate to move and squeeze the compression spring, so that the limiting plate moves out of the limiting groove on the outer circumference of the rotating sleeve and into the limiting groove on the outer circumference of the moving rod. The rotating sleeve can rotate freely. After the adjustment is completed, release the moving collar, squeeze the spring to push it to move in the opposite direction, and drive the limiting plate to reset and enter the limiting groove on the outer circumference of the rotating sleeve, which will enhance the fixing effect and ensure smooth operation.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] By using the set flattening and adjusting components, the hydraulic cylinder is activated, driving the hydraulic rod to descend. The connecting plate moves accordingly, the positioning rods on both sides descend, and the bottom abuts against the connecting sleeve rod, pushing the moving rod so that the moving block slides down the vertical groove. The sleeve plate approaches the fabric, and the descending sleeve plate drives the pressure plate to move. After the pressure plate contacts the fabric, it generates a reaction force according to the fabric thickness, pushing the telescopic column to move in the inner cavity and squeezing the telescopic spring. This achieves adaptive adaptation to fabrics of different thicknesses, always maintaining appropriate pressure to flatten the fabric. When the moving block slides to the bottom of the vertical groove, the pressure spring rebounds, pushing the moving block into the first moving groove. The connecting plate continues to descend, driving the connecting sleeve rod to push the moving rod, so that the moving block moves laterally in the first moving groove. The sleeve plate and pressure plate move laterally accordingly, effectively unfolding the fabric folds and significantly improving the flattening effect.

[0032] After initial flattening, the hydraulic cylinder is restarted, driving the hydraulic rod to rise. The connecting plate rises and pulls the positioning rod, which in turn pulls the connecting sleeve rod, causing the moving block to slide along the first moving groove and approach the vertical groove until it is fully inside the vertical groove. The inner wall of the vertical groove compresses the pressure spring, causing it to retract into the inner groove. When the moving block moves to the top of the vertical groove, the pressure spring rebounds, pushing the moving block into the second moving groove. Subsequently, the hydraulic cylinder is restarted, driving the hydraulic rod to descend. The connecting plate descends and pushes the positioning rod, which in turn pushes the connecting sleeve rod against the moving rod, causing the moving block to move in the second moving groove. This causes the two sleeve plates to move away from each other, preventing them from interfering with each other during subsequent rotation operations.

[0033] Manually rotate the rotating sleeve plate, causing it to rotate. The internal fixing frame rotates accordingly, causing the abutment block on the outer periphery of the central column to rotate. When the abutment block contacts the locking block, the locking block pushes the abutment block to rotate and squeezes the spring sheet. After disengaging, the spring sheet rebounds, pushing the abutment block to reset and contact the limiting block. As the sleeve plate rotates, its side chamfer gradually approaches the fabric. After adjusting the tilt angle, proceed to the next step. Start the hydraulic cylinder to drive the hydraulic rod to rise. The connecting plate rises and pushes the positioning rod, pulling the connecting sleeve rod to drive the moving rod, causing the moving block to move in the second moving groove. This causes the two sleeve plates to move closer to each other in a V-shape. Start the hydraulic cylinder again to drive the hydraulic rod to fall. The connecting plate falls and pushes the positioning rod, pushing the connecting sleeve rod to push the moving rod, causing the moving block to move in the second moving groove. This causes the two sleeve plates to move away from each other. By chamfering and pulling the fabric surface, wrinkles are further reduced. Adjusting the tilt angle of the sleeve plate can adapt to the processing needs of fabrics of different thicknesses. Attached Figure Description

[0052] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] like Figures 1-13As shown, the present invention provides a flattening device for the uppers of combat boots, training shoes, and service leather shoes: It includes a frame 10, which includes a base 11 and a support frame 12. It also includes a flattening assembly 20 and an adjusting assembly 30 mounted on the top of the base 11. The flattening assembly 20 includes a fixing plate 21 fixedly connected to one side of the support frame 12, and two connecting frames 25 fixedly connected to the top of the base 11. A driving component is installed on one side of the fixing plate 21, and a connecting plate 24 is fixedly connected to the bottom of the driving component. The driving component includes a hydraulic cylinder 22 installed on one side of the fixed plate 21. A hydraulic rod 23 is connected between the bottom of the hydraulic cylinder 22 and the connecting plate 24. Two positioning rods 241 are fixedly connected to both sides of the connecting plate 24. A limit plate 242 is fixedly connected to one side of the positioning rod 241. A transverse groove 28 and a clearance groove 281 are opened inside the two connecting frames 25. A threaded rod 282 is threadedly connected to the inner wall of the clearance groove 281, and one end of the threaded rod 282 passes through the clearance groove 281 and is connected to the pressure block 283.

[0054] When flattening the upper material, first, lay the material to be flattened flat on the top surface of the base 11, ensuring that the edge of the material is as close as possible to the horizontal groove 28, in preparation for subsequent fixing operations.

[0055] Next, the fabric is fixed by manually turning the threaded rod 282. As the threaded rod 282 rotates, it will gradually descend along the thread direction. At the same time, the pressure block 283 connected to the threaded rod 282 will descend synchronously with the movement of the threaded rod 282. When the pressure block 283 descends to contact the fabric and applies a certain pressure, the fabric laid flat on the base 11 can be effectively fixed to prevent the fabric from shifting during the subsequent flattening process.

[0056] After the fabric is fixed, the hydraulic cylinder 22 is started. After the hydraulic cylinder 22 starts working, it will drive the hydraulic rod 23 connected to it to descend synchronously. During the descent, the hydraulic rod 23 will drive the connecting plate 24 to move together. Since the connecting plate 24 is equipped with positioning rods 241 on both sides, the positioning rods 241 on both sides will also move down together as the connecting plate 24 descends.

[0057] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, each of the two connecting frames 25 has two symmetrical vertical slots 251 and a first movable slot 252 communicating with the vertical slots 251. A movable block 26 is slidably connected to the inner wall of the vertical slot 251. Each movable block 26 has an inner slot 263 on one side, and a pressure spring 264 is installed on the inner wall of each inner slot 263. A movable rod 261 is installed inside the movable block 26. A limit block 262 is fixedly connected to the side of the movable rod 261. The limit block 262 and the limit plate 242 can restrict the connecting sleeve rod 243 from moving out of the positioning rod 241 and... The outer periphery of the moving rod 261 is connected to the positioning rod 241 via a connecting sleeve rod 243. The moving rod 261 is connected to a sleeve plate 27 via an adjustment assembly 30 on its outer periphery. An elastic element is connected to the bottom of the sleeve plate 27. The elastic element includes several inner cavities 271 opened at the bottom of the sleeve plate 27. A telescopic column 273 is slidably connected to the inner wall of each inner cavity 271. A telescopic spring 272 is connected between the telescopic column 273 and the inner cavity 271. The bottom of the telescopic column 273 is connected to a pressure plate 274. A chamfer 275 is provided on the outer periphery of the sleeve plate 27.

[0058] In the initial state, the moving block 26 is inside the vertical groove 251. As the positioning rod 241 descends, its bottom will abut against the connecting sleeve rod 243. After the connecting sleeve rod 243 is subjected to the abutting force, it begins to push the moving rod 261. Under the push of the connecting sleeve rod 243, the moving rod 261 drives the moving block 26 connected to it to slide down along the vertical groove 251.

[0059] As the moving rod 261 descends, its outer sleeve 27 gradually approaches the fabric. As the sleeve 27 continues to descend, it drives the pressure plate 274 connected to the telescopic column 273 at the bottom of the telescopic spring 272 to move together. During the movement, the pressure plate 274 comes into contact with the fabric. At this time, due to the difference in thickness of different fabrics, the pressure plate 274 will generate a corresponding reaction force according to the actual thickness of the fabric, pushing the telescopic column 273 to move in the inner cavity 271 and squeezing the telescopic spring 272. This elastic deformation characteristic of the telescopic spring 272 enables the pressure plate 274 to adapt to fabrics of different thicknesses and always maintain appropriate pressure to flatten the fabric.

[0060] When the moving block 26 slides down the vertical groove 251 to the bottom, the pressure spring 264, which was originally in a compressed state, begins to play its role. The pressure spring 264 rebounds with its own elastic potential energy, pushing the moving block 26 away from the bottom of the vertical groove 251 and into the first moving groove 252.

[0061] At this time, the connecting plate 24 continues to descend, driving the connecting sleeve rod 243 to move. The connecting sleeve rod 243 abuts against the moving rod 261, causing the moving rod 261 to drive the moving block 26 to move laterally within the first moving groove 252. As the moving rod 261 moves laterally, the sleeve plate 27 on its outer periphery and the pressure plate 274 at the bottom of the sleeve plate 27 also move laterally. During the process of the pressure plate 274 continuously flattening the fabric, this lateral movement can unfold the wrinkles on the fabric, effectively reducing the number of wrinkles on the fabric surface, significantly improving the flattening effect of the fabric, and ensuring that the shoe upper fabric reaches an ideal flat state.

[0062] like Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the adjustment assembly 30 includes a second moving groove 31 inside the connecting frame 25, and a groove 32 and a slot 33 on the outer periphery of the moving rod 261. The outer periphery of the groove 32 is rotatably connected to the sleeve plate 27 via a rotating sleeve plate 321. The slot 33 is connected to the rotating sleeve plate 321 via a one-way component. The one-way component includes several snap-fit ​​blocks 34 fixedly connected to the outer periphery of the slot 33. A fixing frame 341 is fixedly connected to the inner wall of the rotating sleeve plate 321, and a central column 342 is connected to the inner wall of the fixing frame 341. An abutment block 343 that contacts the snap-fit ​​block 34 is rotatably connected to the outer periphery of the central column 342. A limiting block 344 that contacts the abutment block 343 and a spring plate 345 are fixedly connected to the inner wall of the rotating sleeve plate 321. A scale line can be opened on the outer periphery of the moving rod 261. A pointer is connected to the outer periphery of the rotating sleeve plate 321. After rotation, observe the position of the pointer and the scale line, and adjust the rotation angle of the two sleeve plates 27.

[0063] To further reduce fabric wrinkles and improve the flattening effect, after the initial flattening operation is completed, the hydraulic cylinder 22 is activated again. The hydraulic cylinder 22 drives the hydraulic rod 23 to rise synchronously. As the hydraulic rod 23 rises, the connecting plate 24 moves accordingly, which in turn pulls the positioning rods 241 on both sides to rise together. During the rising process, the positioning rods 241 pull the connecting sleeve rod 243, causing the connecting sleeve rod 243 to drive the moving rod 261 and the moving block 26. The moving block 26 slides along the first moving groove 252 and gradually... As the connecting plate 24 continues to rise, the connecting sleeve rod 243 pulls the moving rod 261, causing the moving block 26 to fully enter the vertical groove 251. When the moving block 26 enters the vertical groove 251, the inner wall of the vertical groove 251 will squeeze the pressure spring 264. The pressure spring 264 is forced to retract into the inner groove 263. When the moving block 26 moves to the top of the vertical groove 251, the pressure spring 264, which is under compression, begins to rebound, pushing the moving block 26 into the second moving groove 31.

[0064] To prevent the two sleeve plates 27 from interfering with each other during subsequent rotation operations, after the moving block 26 enters the second moving groove 31, the hydraulic cylinder 22 is activated again, causing it to drive the hydraulic rod 23 to descend synchronously. The descent of the hydraulic rod 23 causes the connecting plate 24 to move together. As the connecting plate 24 continues to descend, the positioning rods 241 on both sides push the connecting sleeve rod 243 to abut the moving rod 261, causing the moving rod 261 to drive the moving block 26 to move within the second moving groove 31. During the movement, the moving rod 261 synchronously drives the sleeve plates 27 to move, causing the two sleeve plates 27 to move away from each other.

[0065] Subsequently, the rotating sleeve 321 is manually rotated, which drives the sleeve 27 to rotate as well. During the rotation, the fixing frame 341 inside the rotating sleeve 321 also rotates, which in turn drives the abutment block 343 on the outer periphery of the central column 342 to rotate as well. When the abutment block 343 rotates to contact the locking block 34, the locking block 34 will push the abutment block 343 to rotate on the outer periphery of the central column 342 and squeeze the spring sheet 345. When the abutment block 343 disengages from the locking block 34, the spring sheet 345 in the squeezed state rebounds, pushing the abutment block 343 to reset and contact the limiting block 344. As the sleeve 27 rotates, the chamfer 275 on the side of the sleeve 27 gradually approaches the fabric. After adjusting the tilt angle of the sleeve 27, the next operation can be carried out.

[0066] Start hydraulic cylinder 22, causing it to drive hydraulic rod 23 to rise synchronously. The rise of hydraulic rod 23 causes connecting plate 24 to move together. As connecting plate 24 continues to rise, positioning rods 241 on both sides push connecting sleeve rod 243 to pull moving rod 261, causing moving rod 261 to move moving block 26 within the second moving groove 31. During the movement, moving rod 261 synchronously moves sleeve plate 27, bringing the two sleeve plates 27 closer together. When the two sleeve plates 27 are close enough to form a V-shape, start hydraulic cylinder 22 again, causing hydraulic rod 23 to descend synchronously. The descent of hydraulic rod 23 causes connecting plate 24 to move together. As the connecting plate 24 continues to descend, the positioning rods 241 on both sides push the connecting sleeve rod 243 to abut the moving rod 261, causing the moving rod 261 to drive the moving block 26 to move within the second moving groove 31. During the movement, the moving rod 261 simultaneously drives the sleeve plate 27 to move, causing the two sleeve plates 27 to move away from each other. The chamfers 275 on the sides of the two sleeve plates 27 further stretch the fabric surface as the sleeve plates 27 move, effectively reducing the generation of wrinkles. At the same time, by adjusting the tilt angle of the sleeve plates 27, the chamfers 275 on the sides of the sleeve plates 27 can adapt to the processing requirements of fabrics of different thicknesses.

[0067] To prevent the sleeve 27 from rotating and deflecting during the pushing process, when the sleeve 27 is subjected to a pushing force, the abutting block 343 on the inner wall of the rotating sleeve 321 on one side of the sleeve 27 will abut against the locking block 34, thereby effectively preventing the sleeve 27 from deflecting due to the pushing force.

[0068] After completing all the above operations, turn the threaded rod 282 to raise it. As the threaded rod 282 rises, the pressure block 283 moves synchronously to release the fixation of the flat material. Then, the pressed fabric can be removed, completing the entire process of flattening and wrinkle optimization of the shoe upper fabric.

[0069] like Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 13 As shown, a fixing component 40 is installed on the outer periphery of the moving rod 261. The fixing component 40 includes a fixing collar 41 fixedly connected to the outer periphery of the moving rod 261. A plurality of extension rods 42 are fixedly connected to one side of the fixing collar 41. One side of each of the extension rods 42 is connected to the top ring 43. A moving collar 44 is slidably connected to the outer periphery of the extension rods 42. A compression spring 47 is sleeved on the outer periphery of each extension rod 42. A limiting groove 45 is opened on the outer periphery of both the moving rod 261 and the rotating sleeve 321. A plurality of limiting plates 46 that contact the limiting groove 45 are fixedly connected to the inner wall of the moving collar 44.

[0070] To further enhance the stability of the sleeve 27 and prevent it from deflecting during operation, when it is necessary to adjust the angle of the sleeve 27, firstly, manually push the moving collar 44 so that it slides on the outer periphery of the extension rod 42. During the sliding of the moving collar 44, it will simultaneously drive the limiting plate 46 to move together and exert a squeezing effect on the compression spring 47, causing the compression spring 47 to deform.

[0071] Continue pushing the moving collar 44 until it drives the limiting plate 46 to completely move out of the limiting groove 45 on the outer periphery of the rotating sleeve 321 and into the corresponding limiting groove 45 on the outer periphery of the moving rod 261. At this time, the rotating sleeve 321 loses the constraint of the limiting plate 46 and can rotate freely so as to adjust the angle of the sleeve 27.

[0072] After the angle of the sleeve plate 27 is adjusted, the moving collar 44 is released. At this time, the compression spring 47, which is under compression, begins to rebound due to its own elastic potential energy, pushing the moving collar 44 to move in the opposite direction, thereby driving the limiting plate 46 to reset. The limiting plate 46 will move back into the limiting groove 45 on the outer periphery of the rotating sleeve plate 321 and fit tightly with the limiting groove 45.

[0073] By using the combination of the limiting plate 46 and the limiting groove 45, the fixing effect of the sleeve 27 can be further enhanced, effectively preventing the sleeve 27 from deflecting during the working process, ensuring that the sleeve 27 always maintains a stable working state, thereby ensuring the smooth progress of the entire shoe upper material processing process.

[0074] A process for flattening the uppers of combat boots, training shoes, and service leather shoes includes the following steps:

[0075] S01: Lay the flat material to be pressed flat on the base 11, so that the edge of the fabric is as close as possible to the horizontal groove 28. Manually turn the threaded rod 282 to lower it, which will drive the pressure block 283 to lower. The pressure block 283 contacts the fabric and applies pressure to complete the fixing and prevent the fabric from shifting during subsequent pressing.

[0076] S02: Start the hydraulic cylinder 22, which drives the hydraulic rod 23, connecting plate 24 and positioning rods 241 on both sides to descend. The positioning rod 241 abuts against the connecting sleeve rod 243, pushing the moving rod 261 to make the moving block 26 slide down the vertical groove 251. The sleeve plate 27 approaches the fabric. After the pressure plate 274 contacts the fabric, it generates a reaction force according to the fabric thickness, pushing the telescopic column 273 to squeeze the telescopic spring 272, adapting to different fabric thicknesses and flattening it. When the moving block 26 slides to the bottom of the vertical groove 251, the pressure spring 264 pushes it into the first moving groove 252. The connecting plate 24 continues to descend, driving the moving block 26 to move laterally in the first moving groove 252. The sleeve plate 27 and the pressure plate 274 move laterally to unfold the fabric pleats.

[0077] S03: After initial flattening, the hydraulic cylinder 22 is restarted to raise the hydraulic rod 23. The connecting plate 24 rises and pulls the positioning rod 241 and the connecting sleeve rod 243. The moving block 26 moves along the first moving groove 252 to approach the vertical groove 251 and enters it. When it moves to the top of the vertical groove 251, the pressure spring 264 pushes it into the second moving groove 31. Then, the hydraulic cylinder 22 is restarted to lower the hydraulic rod 23. The connecting plate 24 lowers and pushes the positioning rod 241 and the connecting sleeve rod 243, causing the moving block 26 to move in the second moving groove 31. This drives the two sleeve plates 27 to move away from each other, preventing subsequent rotation operations from interfering with each other.

[0078] S04: Manually rotate the rotating sleeve 321 to drive the sleeve 27 and the internal fixing frame 341 to rotate. The abutment block 343 on the outer periphery of the central column 342 rotates. When the abutment block 343 contacts the locking block 34, the locking block 34 abuts against it to rotate and squeezes the spring sheet 345. After the contact is broken, the spring sheet 345 pushes it to reset and contacts the limiting block 344. After adjusting the tilt angle of the chamfer 275 on the side of the sleeve 27 close to the fabric, proceed to the next operation.

[0079] S05: Start hydraulic cylinder 22 to raise hydraulic rod 23, connecting plate 24 rises to push positioning rod 241 and connecting sleeve rod 243, driving moving rod 261 to move moving block 26 in second moving groove 31, two sleeve plates 27 approach each other in a V shape, start hydraulic cylinder 22 again to lower hydraulic rod 23, connecting plate 24 lowers to push positioning rod 241 and connecting sleeve rod 243, driving moving rod 261 to move moving block 26 in second moving groove 31, two sleeve plates 27 move away from each other, chamfer 275 pulls the fabric surface to reduce wrinkles, adjust tilt angle to adapt to fabrics of different thicknesses;

[0080] S06: When the sleeve plate 27 is pushed to both sides, the abutment block 343 on the inner wall of the rotating sleeve plate 321 abuts against the locking block 34 to prevent deflection. When adjusting the angle, manually push the moving collar 44 to slide on the outer periphery of the extension rod 42, which drives the limiting plate 46 to move and squeeze the compression spring 47, so that the limiting plate 46 moves out of the limiting groove 45 on the outer periphery of the rotating sleeve plate 321 and into the limiting groove 45 on the outer periphery of the moving rod 261. The rotating sleeve plate 321 can rotate freely. After the adjustment is completed, release the moving collar 44, and the compression spring 47 pushes it to move in the opposite direction, which drives the limiting plate 46 to reset and enter the limiting groove 45 on the outer periphery of the rotating sleeve plate 321, which enhances the fixing effect and ensures smooth operation.

[0081] Working principle: Lay the fabric to be flattened flat on the base 11, and try to get the edge of the fabric close to the horizontal groove 28. Manually turn the threaded rod 282 to make it descend along the thread, which drives the connected pressure block 283 to descend synchronously. When the pressure block 283 contacts the fabric and applies a certain pressure, the fabric is fixed and prevented from shifting during subsequent flattening.

[0082] After fixing is completed, the hydraulic cylinder 22 is activated, which drives the hydraulic rod 23 to descend, thereby moving the connecting plate 24. The positioning rods 241 on both sides descend accordingly. The bottom of the positioning rods 241 abuts against the connecting sleeve rod 243, pushing the moving rod 261 and causing the moving block 26 to slide down along the vertical groove 251. The sleeve plate 27 then approaches the fabric. The sleeve plate 27 descends, causing the pressure plate 274 to move. After the pressure plate 274 contacts the fabric, it generates a reaction force according to the fabric thickness, pushing the telescopic column 273 to move in the inner cavity 271 and squeezing the telescopic spring 272, so that the pressure plate 274 can adapt to fabrics of different thicknesses and maintain appropriate pressure to flatten the fabric. When the moving block 26 slides to the bottom of the vertical groove 251, the pressure spring 264 rebounds, pushing the moving block 26 into the first moving groove 252. The connecting plate 24 continues to descend, driving the connecting sleeve rod 243 to push the moving rod 261, causing the moving block 26 to move laterally in the first moving groove 252. The sleeve plate 27 and the pressure plate 274 move laterally, unfolding the fabric folds and improving the flattening effect.

[0083] After initial flattening, the hydraulic cylinder 22 is activated again, driving the hydraulic rod 23 to rise. The connecting plate 24 rises and pulls the positioning rod 241, which in turn pulls the connecting sleeve rod 243, causing the moving block 26 to slide along the first moving groove 252 and approach the vertical groove 251. Finally, it completely enters the vertical groove 251. The inner wall of the vertical groove 251 squeezes the pressure spring 264, causing it to retract into the inner groove 263. When the moving block 26 moves to the top of the vertical groove 251, the pressure spring 264 rebounds, pushing the moving block 26 into the second moving groove 31.

[0084] To prevent the two sleeves 27 from interfering with each other during subsequent rotation operations, after the moving block 26 enters the second moving groove 31, the hydraulic cylinder 22 is activated again to drive the hydraulic rod 23 to descend. The connecting plate 24 descends and pushes the positioning rod 241, which in turn pushes the connecting sleeve rod 243 to abut the moving rod 261, causing the moving block 26 to move within the second moving groove 31, thereby driving the two sleeves 27 to move away from each other.

[0085] Manually rotate the rotating sleeve 321, causing the sleeve 27 to rotate. The internal fixing frame 341 rotates accordingly, causing the abutment block 343 on the outer periphery of the central column 342 to rotate. When the abutment block 343 contacts the locking block 34, the locking block 34 abuts the abutment block 343 to rotate and squeezes the spring sheet 345. After the contact is broken, the spring sheet 345 rebounds, pushing the abutment block 343 to reset and contact the limiting block 344. As the sleeve 27 rotates, its side chamfer 275 gradually approaches the fabric. After adjusting the tilt angle, proceed to the next step.

[0086] Start the hydraulic cylinder 22 to drive the hydraulic rod 23 to rise, the connecting plate 24 rises to push the positioning rod 241, pull the connecting sleeve rod 243 to drive the moving rod 261, so that the moving block 26 moves in the second moving groove 31, and drives the two sleeve plates 27 to move closer to each other in a V shape. Start the hydraulic cylinder 22 again to drive the hydraulic rod 23 to fall, the connecting plate 24 falls to push the positioning rod 241, push the connecting sleeve rod 243 to abut the moving rod 261, so that the moving block 26 moves in the second moving groove 31, and drives the two sleeve plates 27 to move away from each other. The chamfer 275 pulls the fabric surface to reduce wrinkles, and the tilt angle of the sleeve plates 27 can be adjusted to meet the processing needs of fabrics of different thicknesses.

[0087] When the sleeve 27 is pushed to both sides, the abutment block 343 on the inner wall of the rotating sleeve 321 abuts against the locking block 34 to prevent the sleeve 27 from deflecting due to the pushing force. When adjusting the angle of the sleeve 27, manually push the moving collar 44 to slide on the outer periphery of the extension rod 42, which drives the limiting plate 46 to move and squeeze the compression spring 47. Continue pushing to move the limiting plate 46 out of the limiting groove 45 on the outer periphery of the rotating sleeve 321 and into the limiting groove 45 on the outer periphery of the moving rod 261. At this time, the rotating sleeve 321 can rotate freely. After the adjustment is completed, release the moving collar 44, the compression spring 47 rebounds, and push the moving collar 44 to move in the opposite direction, which drives the limiting plate 46 to reset and re-enter the limiting groove 45 on the outer periphery of the rotating sleeve 321, which enhances the fixing effect of the sleeve 27, prevents deflection, and ensures smooth operation.
