Description

Technical Field

[0001] This invention relates to the field of footwear manufacturing technology, specifically to a precision sole pressing production device for footwear molding and its usage method. Background Technology

[0002] In the footwear production process, the sole pressing process is a core step that determines the quality, comfort, and lifespan of the footwear. Its core requirements are to achieve alignment, uniform pressure, and stable shaping of the sole and upper. The sole pressing production device used in footwear molding, namely the sole pressing machine commonly used in the footwear industry, is a core piece of equipment used for bonding and shaping the upper and sole. Through hydraulic or pneumatic mechanisms, vertical and lateral pressure is applied to the shoe body, so that the glued upper and sole are tightly bonded, air is expelled, and the material is cured and shaped, ensuring bonding strength and shoe shape regularity, and improving footwear production efficiency and finished product quality.

[0003] Existing footwear molding and sole pressing production equipment places the glued footwear inside the pressing base of the pressing device, controls hydraulic components to press the footwear up and down, and then uses external stamping equipment to press the inside of the pressing airbag to press the sidewalls of the footwear. However, existing devices mostly use a single pressure output mode, which cannot accurately distribute pressure according to the pressing requirements of different parts of the footwear, resulting in uneven pressing. This can lead to either localized incomplete pressing and subsequent glue separation, or excessive pressure causing damage to the sidewall decorations and deformation of the sole. It is difficult to adapt to the pressing requirements of different sizes of footwear, so further improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a precision sole pressing production device for shoe molding and its usage method, in order to solve the problems mentioned in the background art, that existing devices mostly adopt a single pressure output mode, which cannot accurately distribute pressure according to the pressing requirements of different parts of the shoe, resulting in uneven pressing, either causing local incomplete pressing and later glue separation, or excessive pressure causing damage to the side wall decorations of the shoe and deformation of the sole, making it difficult to adapt to the pressing requirements of different specifications of shoes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision sole pressing production device for shoe molding, comprising a main body, a pressing base on the surface of the main body, and hydraulic components at the bottom and top of the pressing base; a pressing airbag for wrapping the shoe on the inner wall of the pressing base; a side pressing mechanism for uniformly pressing the sidewall of the shoe between the inner wall of the pressing base and the pressing airbag; the side pressing mechanism including a movable guide rail disposed on the inner sidewall of the pressing base, a movable seat driven by a servo motor on the outer wall of the movable guide rail, and an adjusting seat at the end of the movable seat away from the guide rail; a fixed frame on the outer wall of the adjusting seat, and a pressing roller on the sidewall of the fixed frame; an adjusting component for adaptively adjusting the side pressing pressure between the fixed frame and the adjusting seat; and a swing pressing component for enhancing the pressing effect of shoes of different specifications on the sidewall of the adjusting seat.

[0006] Preferably, the moving guide rail is designed in a ring shape, and the moving seat moves along the track of the moving guide rail. The servo motor used to drive the moving seat is electrically connected to the control panel of the main body of the device via wires.

[0007] Preferably, adjustment frames are slidably installed on both outer walls of the movable seat, and the ends of the adjustment frames are rotatably connected to the side walls of the adjustment seat. An electric push rod is provided between the adjustment frame and the movable seat, and the output end of the electric push rod is connected to the adjustment frame through a ball joint. The electric push rod is electrically connected to the control panel of the main body of the device through a wire.

[0008] Preferably, a buffer slide rod is fixedly installed on the side of the fixed frame away from the pressing roller, and a buffer spring is sleeved on the outer wall of the buffer slide rod. Two sets of buffer slide rods are symmetrically arranged, and the buffer slide rods are slidably connected to the adjusting seat. One end of the buffer spring abuts against the outer wall of the adjusting seat, and the other end of the buffer spring abuts against the outer wall of the fixed frame.

[0009] Preferably, the adjustment assembly includes an adjustment slider that is slidably mounted on the outer wall of the adjustment seat, and two sets of adjustment sliders are symmetrically arranged. An adjustment plate is slidably mounted on the outer wall of the adjustment seat near the fixed frame, and an adjustment spring is fixedly mounted on the outer wall of the adjustment plate. A pressing block is provided at the end of the buffer slide rod away from the fixed frame.

[0010] Preferably, the adjusting slider has an L-shaped cross-section, with one end of the adjusting slider contacting the end of the extrusion block, and the outer wall of the side of the adjusting slider that contacts the extrusion block is beveled. The adjusting plate is located between the two sets of adjusting sliders, and the outer wall of the side of the adjusting slider that contacts the adjusting plate is beveled. One end of the adjusting spring abuts against the fixed frame, and the other end of the adjusting spring abuts against the adjusting plate, for adaptively adjusting the extrusion force of the pressing roller on the shoe according to the contour of the shoe sidewall.

[0011] Preferably, the swing pressing assembly includes protrusions at both ends of the adjusting plate, and an mounting plate is fixedly installed on the inner wall of the pressing base, and the outer wall of the mounting plate is provided with swing protrusions.

[0012] Preferably, the protrusion ends are hemispherical, and the protrusions are symmetrically distributed at the top and bottom of the adjustment plate. The mounting plate has two sets of protrusions symmetrically arranged at the top and bottom of the adjustment plate. The cross-section of the swing protrusion is trapezoidal, and the width of the end of the swing protrusion closest to the moving guide rail is smaller than that of the other end. The swing protrusions are evenly distributed along the edge of the mounting plate. The outer wall of the swing protrusion contacts the protrusion ends, and the swing protrusions on the outer walls of the two sets of mounting plates are staggered, which is used to adjust the swing frequency according to different sizes of shoes.

[0013] Preferably, the method includes the following steps: S1: Place the shoes to be pressed inside the pressing base, start the main body of the device, and the hydraulic components press the top and bottom of the shoes. Then, the external pressurizing equipment presses the pressing airbag to press the glued area between the upper and the sole of the shoes, thus achieving the initial bonding and positioning of the sole and upper of the shoes. S2: Start the side pressure mechanism, adjust the initial position of the pressing roller with the electric push rod to make it fit the shoe side wall, then start the servo motor, the servo motor drives the moving seat to move at a constant speed along the circular moving guide rail, and then drives the adjusting seat, the fixed frame and the pressing roller to move synchronously, so that the pressing roller performs circular pressing along the shoe contour, initially enhancing the pressing and bonding effect; S3: The adjustment components start synchronously. When the pressing roller contacts the side wall of the shoe and applies lateral pressure, the fixed frame is driven by the reaction force of the shoe to slide along the adjustment seat. The buffer spring undergoes elastic deformation to achieve initial pressure buffering. At the same time, the extrusion block pushes the L-shaped adjustment slider to slide. The adjustment slider drives the adjustment plate to move through the inclined plane and causes the adjustment spring to deform. The elastic restoring force of the adjustment spring is used to adaptively adjust the extrusion force of the pressing roller on the side wall of the shoe to adapt to the contour requirements of different parts of the shoe. S4: The swing pressing component moves in conjunction with the side pressing mechanism. The protrusions at both ends of the adjusting plate move with the adjusting plate and contact the staggered swing protrusions on the mounting plate on the inner wall of the pressing base. Under the guidance of the swing protrusions, the pressing roller is driven to swing regularly. The swing frequency is adaptively adjusted according to the size and specifications of the shoes to fully press the complex parts such as the side corners and curvatures of the shoes, further improving the pressing accuracy and fit, and ensuring that the sole and upper are tightly bonded in all directions.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention solves the problem of uneven side pressure in existing devices by setting a side pressure mechanism between the inner wall of the pressure base and the pressure airbag, and cooperating with the annular moving guide rail and the moving seat driven by the servo motor to achieve uniform annular movement of the pressure roller along the side wall of the shoe. This ensures that all parts of the side wall of the shoe are subjected to uniform pressure, effectively avoids the later glue separation and internal air bubbles caused by local incomplete pressing, and at the same time ensures the regularity of the shoe shape and improves the quality of shoe molding.

[0015] 2. By adjusting the components and buffering components, the buffer slide and buffer spring can achieve initial pressure buffering. The adjusting slider, adjusting plate and adjusting spring can adaptively adjust the extrusion pressure of the pressing roller according to the contour of the shoe side wall, avoiding damage to the shoe side wall decorations and deformation of the sole caused by a single pressure output. It can adapt to the pressing needs of shoes of different specifications and contours and improve the versatility of the device.

[0016] 3. By cooperating with the protrusions of the swing pressing component and the staggered swing protrusions, the contact between the protrusions and the swing protrusions during the movement of the adjusting plate driven by the moving seat can drive the pressing roller to produce regular swinging, which enhances the pressing effect on complex parts such as the side corners and curvatures of the shoe, further improving the pressing accuracy and fit, ensuring that the sole and upper are tightly bonded in all directions, and the swing pressing component can adaptively adjust the swing frequency according to the size of the shoe to ensure pressure adaptability.

[0019] 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.

[0020] Example 1: Please refer to Figures 1-7The present invention provides the following technical solution: a precision sole pressing production device for shoe molding, comprising a device body 1, a pressing base 2 provided on the surface of the device body 1, and hydraulic components provided at the bottom and top of the pressing base 2; a pressing airbag 201 for wrapping the shoe is provided on the inner wall of the pressing base 2; a side pressing mechanism for uniformly pressing the side wall of the shoe is provided between the inner wall of the pressing base 2 and the pressing airbag 201; the side pressing mechanism includes a moving guide rail 202 provided on the inner side wall of the pressing base 2, and a moving seat 3 driven by a servo motor provided on the outer wall of the moving guide rail 202; an adjusting seat 4 is provided at the end of the moving seat 3 away from the guide rail; a fixing frame 5 is provided on the outer wall of the adjusting seat 4, and a pressing roller 501 is provided on the side wall of the fixing frame 5; the moving guide rail 202 is generally circular in design, and the moving seat 3 moves along the trajectory of the moving guide rail 202 and is used to drive the moving seat. The servo motor of the device 3 is electrically connected to the control panel of the main body 1 via a wire. Adjustment frames 301 are slidably installed on both outer walls of the movable seat 3, and the ends of the adjustment frames 301 are rotatably connected to the side wall of the adjustment seat 4. An electric push rod 302 is provided between the adjustment frame 301 and the movable seat 3, and the output end of the electric push rod 302 is connected to the adjustment frame 301 via a ball joint. The electric push rod 302 is electrically connected to the control panel of the main body 1 via a wire. A buffer slide rod 502 is fixedly installed on the side of the fixed frame 5 away from the pressing roller 501, and a buffer spring 503 is sleeved on the outer wall of the buffer slide rod 502. Two sets of buffer slide rods 502 are symmetrically arranged, and the buffer slide rods 502 are slidably connected to the adjustment seat 4. One end of the buffer spring 503 abuts against the outer wall of the adjustment seat 4, and the other end of the buffer spring 503 abuts against the outer wall of the fixed frame 5.

[0021] During operation, the glued shoes are first placed inside the pressing base 2. The pressing airbag 201 initially wraps and positions the shoes. Then, the main body 1 controls the hydraulic components at the bottom and top of the pressing base 2 to activate, pressing the shoes vertically. The pressing airbag 201 is inflated via the control panel to press the shoes together, achieving initial adhesion between the sole and the upper. Simultaneously, the side pressing mechanism is activated, activating the electric push rod 302. The electric push rod 302 initially adjusts the distance between the pressing roller 501 and the shoes according to different shoe sizes. The control panel of the main body 1 controls the servo motor through wires, driving the moving seat 3 to move at a constant speed along the circular moving guide rail 202. The moving seat 3 drives the adjusting seat 4, the fixed frame 5 and the pressing roller 501 to move synchronously, so that the pressing roller 501 moves along the circular trajectory of the shoe side wall. With the wrapping effect of the pressing airbag 201, uniform lateral pressure is applied to the side wall of the shoe, which initially solves the problem of uneven lateral pressure in the existing device and lays the foundation for subsequent precise pressing. The whole process is automatically controlled by the control panel, reducing manual intervention.

[0022] Example 2: Please refer to Figures 3-7Based on Embodiment 1, an adjustment component is also disclosed, the specific structure of which is as follows: An adjustment component for adaptively adjusting the lateral pressure is provided between the fixed frame 5 and the adjustment seat 4. The adjustment component includes an adjustment slider 401 slidably mounted on the outer wall of the adjustment seat 4, and two sets of adjustment sliders 401 are symmetrically arranged. An adjustment plate 402 is slidably mounted on the outer wall of the adjustment seat 4 near the fixed frame 5, and an adjustment spring 403 is fixedly mounted on the outer wall of the adjustment plate 402. A pressing block 504 is provided at the end of the buffer slide rod 502 away from the fixed frame 5; the adjustment slider 401... The cross-section is L-shaped, and one end of the adjusting slider 401 is in contact with the end of the extrusion block 504. The outer wall of the side of the adjusting slider 401 in contact with the extrusion block 504 is designed with an inclined surface. The adjusting plate 402 is located between the two sets of adjusting sliders 401, and the outer wall of the side of the adjusting slider 401 in contact with the adjusting plate 402 is designed with an inclined surface. One end of the adjusting spring 403 abuts against the fixing frame 5, and the other end of the adjusting spring 403 abuts against the adjusting plate 402. It is used to adaptively adjust the extrusion force of the pressing roller 501 on the shoe according to the contour of the shoe side wall.

[0023] The adjustment component is used to adaptively adjust the side pressure to adapt to the pressing needs of shoes of different sizes and contours. Its operation relies on the linkage between the cushioning component and the adjustment structure. When the pressing roller 501 contacts the side wall of the shoe and applies pressure, the fixed frame 5 receives the reaction force from the shoe, causing the cushioning slide 502 to slide along the adjustment seat 4. The cushioning spring 503 on the outer wall of the cushioning slide 502 undergoes elastic deformation, achieving initial pressure cushioning and preventing damage to the shoe from excessive instantaneous pressure. Simultaneously, the squeezing block 504 at the end of the cushioning slide 502 away from the fixed frame 5 moves with the cushioning slide 502, and the squeezing block 504 interacts with the adjustment... The inclined surface of slider 401 contacts and pushes two sets of symmetrically arranged L-shaped adjusting sliders 401 to slide along the adjusting seat 4. The adjusting slider 401 pushes the adjusting plate 402 to slide along the adjusting seat 4 through the inclined surface of its contact with the adjusting plate 402, causing the adjusting spring 403 on the outer wall of the adjusting plate 402 to undergo elastic deformation. The elastic restoring force of the adjusting spring 403 acts in the opposite direction on the adjusting plate 402, the adjusting slider 401 and the extrusion block 504, thereby adjusting the extrusion pressure of the pressing roller 501 on the side wall of the shoe, realizing adaptive pressure adjustment according to the contour of the side wall of the shoe, and ensuring that the pressing pressure is accurately adapted to the needs of each part of the shoe.

[0024] Example 3: Please refer to Figures 2-7Based on Embodiment 1, a swing pressing assembly is also disclosed, the specific structure of which is as follows: The side wall of the adjusting seat 4 is provided with a swing pressing assembly for enhancing the pressing effect of shoes of different sizes. The swing pressing assembly includes protrusions 6 at both ends of the adjusting plate 402, and an mounting plate 7 is fixedly installed on the inner wall of the pressing base 2. The outer wall of the mounting plate 7 is provided with swing protrusions 701. The ends of the protrusions 6 are hemispherical, and the protrusions 6 are symmetrically distributed at the top and bottom of the adjusting plate 402. The mounting plate 7 is symmetrically arranged with two sets at the top and bottom of the adjusting plate 402. The cross section of the swing protrusions 701 is trapezoidal, and the width of the end of the swing protrusions 701 near the moving guide rail 202 is smaller than that of the other end. The swing protrusions 701 are evenly distributed along the edge of the mounting plate 7. The outer wall of the swing protrusions 701 is in contact with the ends of the protrusions 6, and the swing protrusions 701 on the outer walls of the two sets of mounting plates 7 are staggered, which is used to adjust the swing frequency according to different sizes of shoes.

[0025] The swing pressing assembly is used to adaptively enhance the pressing effect of complex parts of the sidewall of shoes according to different specifications. Its operation is linked with the side pressing mechanism. When the moving seat 3 drives the adjusting seat 4 and the adjusting plate 402 to move along the moving guide rail 202, the hemispherical protrusions 6 symmetrically distributed at both ends of the adjusting plate 402 move synchronously with the adjusting plate 402. On the two sets of symmetrical mounting plates 7 fixedly installed on the inner wall of the pressing base 2, the trapezoidal swing protrusions 701 distributed at equal intervals contact the ends of the protrusions 6. Since the swing protrusions 701 on the two sets of mounting plates 7 are staggered, and the width of the swing protrusion 701 near the moving guide rail 202 is smaller than that of the other end, the swing protrusions 701 are not as wide as the other end. At one end, as the adjusting plate 402 moves, the protrusion 6 will contact the swing protrusion 701 at different positions in sequence. Guided by the swing protrusion 701, the adjusting plate 402 drives the fixed frame 5 and the pressing roller 501 to swing regularly. At the same time, the distribution design of the swing protrusion 701 can change the contact frequency between the protrusion 6 and the swing protrusion 701 according to the size and specifications of the shoes, thereby adaptively adjusting the swing frequency of the pressing roller 501, ensuring more thorough pressing of complex parts such as the side corners and curvatures of the shoes, further improving the pressing accuracy and fit, and ensuring that the sole and upper are tightly bonded in all directions.

[0026] Based on the above embodiments, please refer to Figures 1-7 The usage method includes the following steps: S1: Place the shoes to be pressed inside the pressing base 2, start the main body 1 of the device, and the hydraulic component presses the top and bottom of the shoes. Then, the external pressurizing equipment presses the pressing airbag 201 to press the adhesive joint between the upper and the sole of the shoes, so as to achieve the initial bonding and positioning of the sole and upper of the shoes. S2: Start the side pressure mechanism, adjust the initial position of the pressing roller 501 by the electric push rod 302 to make it maintain a suitable distance with the side wall of the shoe, and then start the servo motor. The servo motor drives the moving seat 3 to move at a constant speed along the annular moving guide rail 202, which in turn drives the adjusting seat 4, the fixed frame 5 and the pressing roller 501 to move synchronously, so that the pressing roller 501 performs annular pressing along the contour of the shoe, initially enhancing the pressing and bonding effect; S3: The adjustment components start synchronously. When the pressing roller 501 contacts the side wall of the shoe and applies lateral pressure, the fixed frame 5 is driven by the reaction force of the shoe to slide the buffer slide rod 502 along the adjustment seat 4. The buffer spring 503 undergoes elastic deformation to achieve initial pressure buffering. At the same time, the extrusion block 504 pushes the L-shaped adjustment slider 401 to slide. The adjustment slider 401 drives the adjustment plate 402 to move through the inclined surface and causes the adjustment spring 403 to deform. The elastic restoring force of the adjustment spring 403 is used to adaptively adjust the extrusion force of the pressing roller 501 on the side wall of the shoe to adapt to the contour requirements of different parts of the shoe. S4: The swing pressing component moves in conjunction with the side pressing mechanism. The protrusions 6 at both ends of the adjusting plate 402 move with the adjusting plate 402 and contact the staggered swing protrusions 701 on the mounting plate 7 on the inner wall of the pressing base 2. Under the guidance of the swing protrusions 701, the pressing roller 501 is driven to swing regularly. The swing frequency is adaptively adjusted according to the size and specifications of the shoes to fully press the complex parts such as the side corners and curvatures of the shoes, further improving the pressing accuracy and fit, and ensuring that the sole and upper are tightly bonded in all directions.

[0027] Working principle: When this precision sole pressing production device for shoe molding is working, the glued shoe is first placed inside the pressing base 2. The pressing airbag 201 initially wraps and positions the shoe. Then, the main body 1 controls the hydraulic components at the bottom and top of the pressing base 2 to start, pressing the shoe vertically. At the same time, the pressing airbag 201 is inflated through the control panel to press the shoe around, achieving initial adhesion between the sole and the upper. Simultaneously, the side pressing mechanism is activated, first starting the electric push rod 302, according to different specifications. The initial adjustment of the distance between the pressing roller 501 and the shoe is performed. Then, the control panel of the main body 1 controls the servo motor via wires to drive the moving seat 3 to move at a constant speed along the annular guide rail 202. The moving seat 3 drives the adjusting seat 4, the fixed frame 5, and the pressing roller 501 to move synchronously, so that the pressing roller 501 moves along the annular trajectory of the shoe's side wall. With the wrapping effect of the pressing airbag 201, uniform lateral pressure is applied to the side wall of the shoe, initially solving the problem of uneven lateral pressure in existing devices and laying the foundation for subsequent precise pressing. This lays the foundation; during this process, the adjusting components work synchronously, relying on the linkage between the buffer components and the adjusting structure. When the pressure roller 501 contacts the side wall of the shoe and applies pressure, the fixed frame 5 receives the reaction force from the shoe, causing the buffer slide rod 502 to slide along the adjusting seat 4. The buffer spring 503 on the outer wall of the buffer slide rod 502 undergoes elastic deformation to achieve initial pressure buffering, preventing damage to the shoe from excessive instantaneous pressure. At the same time, the squeezing block 504 at the end of the buffer slide rod 502 away from the fixed frame 5 moves with the buffer slide rod 502. The inclined surface of the adjusting slider 401 contacts and pushes two sets of symmetrically arranged L-shaped adjusting sliders 401 to slide along the adjusting seat 4. The adjusting slider 401 then pushes the adjusting plate 402 to slide through its inclined surface that contacts the adjusting plate 402, causing the adjusting spring 403 on the outer wall of the adjusting plate 402 to undergo elastic deformation. The elastic restoring force of the adjusting spring 403 is used to reverse the squeezing force of the pressing roller 501 on the side wall of the shoe, so as to realize the adaptive pressure adjustment according to the contour of the side wall of the shoe, and ensure that the pressing pressure is accurately adapted to the needs of each part of the shoe.The swing pressing assembly is linked with the side pressing mechanism. When the moving seat 3 drives the adjusting seat 4 and the adjusting plate 402 to move along the moving guide rail 202, the hemispherical protrusions 6 symmetrically distributed at both ends of the adjusting plate 402 move synchronously with the adjusting plate 402 and contact the ends of the trapezoidal swing protrusions 701 evenly distributed on the two sets of symmetrical mounting plates 7 on the inner wall of the pressing base 2. Since the swing protrusions 701 on the two sets of mounting plates 7 are staggered and the width is smaller at the end closer to the moving guide rail 202, as the adjusting plate 402 moves, the protrusions 6 will sequentially contact the ends of the protrusions at different positions. The oscillating protrusions 701 contact the shoe, and under the guidance of the oscillating protrusions 701, the adjusting plate 402 drives the fixing frame 5 and the pressing roller 501 to oscillate regularly. The distribution design of the oscillating protrusions 701 can adaptively adjust the oscillation frequency of the pressing roller 501 according to the size and specifications of the shoes, ensuring more thorough pressing of complex parts such as the side corners and curves of the shoes, further improving pressing accuracy and fit, and ensuring a tight bond between the sole and the upper in all directions. The entire process is automated through the control panel, reducing manual intervention.

8. The precision sole pressing production device for shoe molding according to claim 7, characterized in that: The protrusion (6) has a hemispherical end and is symmetrically distributed at the top and bottom of the adjustment plate (402). The mounting plate (7) has two sets of symmetrically arranged at the top and bottom of the adjustment plate (402). The swing protrusion (701) has a trapezoidal cross section and the width of the end of the swing protrusion (701) closest to the moving guide rail (202) is smaller than that of the other end. The swing protrusion (701) is evenly distributed along the edge of the mounting plate (7). The outer wall of the swing protrusion (701) is in contact with the end of the protrusion (6). The swing protrusions (701) on the outer wall of the two sets of mounting plates (7) are staggered and are used to adjust the swing frequency according to different sizes of shoes.

9. A method of using a precision sole pressing production device for shoe molding, applicable to the precision sole pressing production device for shoe molding as described in any one of claims 1-8, characterized in that: The method includes the following steps: S1: Place the shoes to be pressed inside the pressing base (2), start the main body of the device (1), the hydraulic components press the top and bottom of the shoes, and then the external pressurizing equipment presses the pressing airbag (201) to press the upper and sole of the shoes to achieve the initial bonding and positioning of the sole and upper of the shoes. S2: Start the side pressing mechanism and adjust the initial position of the pressing roller (501) by the electric push rod (302) to make it maintain a suitable distance with the side wall of the shoe. Then start the servo motor. The servo motor drives the moving seat (3) to move at a constant speed along the circular moving guide rail (202), which in turn drives the adjusting seat (4), the fixed frame (5) and the pressing roller (501) to move synchronously, so that the pressing roller (501) performs circular pressing along the contour of the shoe, initially enhancing the pressing and bonding effect. S3: The adjustment components start synchronously. When the pressing roller (501) contacts the side wall of the shoe and applies lateral pressure, the fixed frame (5) is driven by the reaction force of the shoe to slide the buffer slide (502) along the adjustment seat (4). The buffer spring (503) undergoes elastic deformation to achieve initial pressure buffering. At the same time, the extrusion block (504) pushes the L-shaped adjustment slider (401) to slide. The adjustment slider (401) drives the adjustment plate (402) to move through the inclined plane and causes the adjustment spring (403) to deform. The elastic restoring force of the adjustment spring (403) is used to adaptively adjust the extrusion force of the pressing roller (501) on the side wall of the shoe to adapt to the contour requirements of different parts of the shoe. S4: The swing pressing component moves in conjunction with the side pressing mechanism. The protrusions (6) at both ends of the adjusting plate (402) move with the adjusting plate (402) and contact the staggered swing protrusions (701) on the inner wall mounting plate (7) of the pressing base (2). Under the guidance of the swing protrusions (701), the pressing roller (501) is driven to swing regularly. The swing frequency is adaptively adjusted according to the size and specifications of the shoes. The complex parts such as the side corners and arcs of the shoes are fully pressed, further improving the pressing accuracy and fit, so that the sole and the upper are tightly bonded in all directions.
