Description

Technical Field

[0001] This invention relates to the field of footwear manufacturing technology, specifically a footwear compactor and compaction method based on flexible extrusion. Background Technology

[0002] In the shoe manufacturing process, a special compaction machine is used to compact the four sides of the shoe body. The core purpose is to firmly press and bond the upper and the sole together, ensuring the stability and durability of the finished product structure. Specifically, this process usually involves setting opposing molds at both ends of the shoe body in the longitudinal direction. The molds move in opposite directions to apply directional compression to the toe and heel areas. On the left and right sides of the shoe body, airbags are inflated to apply lateral pressure, thus completing the all-round compression.

[0003] However, this traditional method has obvious defects in actual production: since the shoe body is placed directly between the two molds, it lacks effective support during the compression process, and the toe area is very prone to upward warping and deformation. This can easily lead to uneven pressure distribution, local underpressure, or weak adhesion in the key bonding areas between the upper and the sole, which seriously affects the strength and consistency of the compression bonding. Since the air bladder usually expands into an approximately cylindrical shape after inflation, its pressure distribution is prone to unevenness. In addition, the curved contour of the shoe side can easily lead to uneven pressure transmission on the shoe side and insufficient pressure at the edges, reducing the stability and reliability of the overall compression quality. Summary of the Invention

[0004] The purpose of this invention is to provide a shoe-making compaction machine and compaction method based on flexible extrusion, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A shoe-making compactor based on flexible extrusion includes a worktable and side plates fixed to the worktable, with the upper part of the worktable arranged in a U-shape. Two pressure blocks are movable on the workbench. The two pressure blocks are arranged opposite each other, and an arc-shaped notch is provided on one of their opposite sides. The shoe is placed between the two pressure blocks. The two pressure blocks can be driven by the opposing drive mechanism on the workbench to move toward the heel and the toe of the shoe respectively. The workbench is equipped with two pressure strips made of elastic latex material. The two pressure strips are located on both sides of the pressure block, and a pressure roller is movably installed on the side of each pressure strip away from the pressure block. The pressure roller can be driven by the transverse movement mechanism on the workbench to move along the length of the pressure strip. A cylinder is fixedly installed on the top of the side plate. The movable end of the cylinder is equipped with a telescopic positioning mechanism. The movable end of the cylinder is also connected to the transverse movement mechanism through a transmission mechanism. After the cylinder drives the telescopic positioning mechanism into the shoe, the telescopic positioning mechanism can move towards the toe of the shoe. The movable end of the cylinder drives the transmission mechanism to trigger, so that the pressure roller applies pressure to the side of the shoe through the pressure strip.

[0006] As described above, the shoe compactor based on flexible extrusion has a first mounting groove on the worktable. The opposing drive mechanism includes a first linear drive module installed in the first mounting groove and two transverse seats symmetrically arranged on the first linear drive module. The first linear drive module can drive the two transverse seats to move towards each other. The worktable is also symmetrically provided with two guide grooves, and a fitting block is slidably fitted into each of the two guide grooves. The two fitting blocks are respectively fixed to the two transverse seats, and the pressure block is connected to the fitting block through an elastic component.

[0007] As described above, the shoe-making compactor based on flexible extrusion includes: a guide plate fixedly mounted on the interlocking block, a telescopic rod slidably fitted with the guide plate, and a cylindrical spring located inside the guide plate. One end of the cylindrical spring is connected to the inner wall of the guide plate, and the other end is connected to a frustum fixedly disposed at the head end of the telescopic rod. The tail end of the telescopic rod is fixedly connected to the pressure block.

[0008] As described above, the shoe compactor based on flexible extrusion includes a telescopic positioning mechanism comprising a multi-section telescopic structure installed at the movable end of the cylinder. When the multi-section telescopic structure is in a retracted state, it can be driven by the cylinder to move down into the shoe. The multi-section telescopic structure includes a guide plate fixed to the movable end of the cylinder and multiple telescopic joints connected to the guide plate. The guide plate and the multiple telescopic joints are sequentially and slidably connected in a sealed manner. The end of the guide plate that is in communication with the telescopic joint is provided with a first stop and a second stop, respectively. The end of the telescopic joint is also provided with a limiting protrusion that cooperates with the first stop and the second stop. The inner wall of the telescopic joint is provided with an air hole, and the guide plate is provided with an air inlet. When air is pumped into the guide plate through the air inlet, the multiple telescopic joints can be caused to perform an extension action. The bottom of the telescopic joint, which is away from the guide plate, is also provided with a protrusion, which is flush with the bottom of both the telescopic joint and the guide plate.

[0009] As described above, the shoe compactor based on flexible extrusion has a second mounting groove on the inner side of the workbench. The transverse movement mechanism includes a second linear drive module installed in the second mounting groove and a movable seat on the second linear drive module. The movable seat is connected to the pressure roller through a telescopic arm assembly, and the telescopic arm assembly is connected to the transmission mechanism.

[0010] As described above, the shoe compactor based on flexible extrusion includes a first connecting arm fixed to the movable seat and a second connecting arm slidably fitted with the first connecting arm. The pressure roller is rotatably mounted on the end of the second connecting arm away from the movable seat, and the second connecting arm is connected to the transmission mechanism.

[0011] As described above, the shoe compactor based on flexible extrusion has the following transmission mechanism: a follower structure is provided on the side plate, the follower structure is connected to the second connecting arm, and a sliding engagement component is provided between the follower structure and the movable end of the cylinder.

[0012] As described above, the shoe compactor based on flexible extrusion includes a follower structure comprising a guide rail fixed to the side plate, a slider slidably fitted on the guide rail, and a cross arm fixed to the slider. A sleeve plate is fixed on the second connecting arm, the sleeve plate being adapted to the cross arm, and the cross arm passing through the sleeve plate and slidably connected to the sleeve plate.

[0013] As described above, the shoe-making compactor based on flexible extrusion includes a sliding assembly comprising a driven plate fixed to the slider and a follower arm fixed to the movable end of the cylinder. A drive column is fixed to one end of the follower arm facing the driven plate, and the driven plate is provided with a groove adapted to the drive column. The drive column passes through the groove and is slidably connected to the driven plate. The groove includes a first groove segment and a second groove segment connected together. The first groove segment is vertically arranged, and the second groove segment is inclined. When the cylinder drives the drive column to move downward, and the drive column moves in the second groove segment, it can cause the driven plate to drive the slider to slide toward the midpoint of the guide rail.

[0014] A shoe-making compaction method, employing the aforementioned shoe-making compaction machine based on flexible extrusion, includes the following steps: Step 1: Place the shoe between the two pressure blocks. The moving end of the cylinder extends downward until the multi-section telescopic structure, which is in a contracted state, enters the shoe and performs the unfolding action inside the shoe. Step two: The moving end of the cylinder continues to move, causing the multi-section telescopic structure in the unfolded state to apply pressure and position the two ends of the shoe sole. The transmission mechanism is triggered, causing the pressure roller to apply pressure to the side of the shoe through the pressure strip. Step 3: The opposing drive mechanism works, driving the two pressure blocks to move closer to each other. The two pressure blocks apply pressure to the toe and heel of the shoe respectively. The lateral movement mechanism works, driving the pressure roller to roll along the side of the pressure strip away from the shoe, and performing flexible compression on the side of the shoe. Step four, processing complete, remove the shoes from the workbench.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, initially, the multi-section telescopic structure remains in a contracted state. The cylinder drives it downwards, entering the shoe from the shoe opening. It then begins to unfold inside the shoe, switching to the unfolded state. The protrusions move towards the toe. Finally, under the pressure of the cylinder, the unfolded multi-section telescopic structure can apply pressure to both ends of the sole, achieving effective positioning of the shoe. This prevents the toe from warping when the pressure blocks apply pressure to both ends of the shoe, avoiding uneven pressure distribution, local underpressure, or weak adhesion in the key bonding area between the upper and the sole, which would seriously affect the strength and consistency of the bonding. Secondly, this invention provides a pressure roller on each side of the shoe. The pressure roller applies pressure to the side of the shoe through a pressure strip. Driven by the lateral movement mechanism, the pressure roller can roll along the side of the pressure strip away from the shoe, thereby achieving full and flexible compression of the side of the shoe, promoting bonding. Compared with the compression method using an airbag that inflates, this invention effectively improves the fullness of compression, avoids the problem of uneven pressure distribution caused by the expansion characteristics of the airbag, improves the uniformity of pressure transmission on the side of the shoe, and avoids insufficient pressure at the edges, thereby reducing the stability and reliability of the overall pressing quality.

[0030] 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.

[0031] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0032] Please see Figures 1-11 In this embodiment, a shoe-making compactor based on flexible extrusion includes a workbench 1 and a side plate 2 fixed to the workbench 1. The upper part of the workbench 1 is arranged in a U-shape. Two pressure blocks 9 are movably mounted on the workbench 1. The two pressure blocks 9 are arranged opposite each other, and an arc-shaped notch 901 is provided on one side of the opposite side. The shoe is placed between the two pressure blocks 9. The two pressure blocks 9 can be driven by the opposing drive mechanism on the workbench 1 to move towards the heel and the toe of the shoe respectively. The workbench 1 is provided with two pressure strips 13 made of elastic latex material. The two pressure strips 13 are located on both sides of the pressure block 9, and a pressure roller 12 is movably provided on the side of the two pressure strips 13 away from the pressure block 9. The pressure roller 12 can be driven by the transverse movement mechanism provided on the workbench 1 to move along the length direction of the pressure strip 13. A cylinder 21 is fixedly installed on the top of the side plate 2. The movable end of the cylinder 21 is provided with a telescopic positioning mechanism. The movable end of the cylinder 21 is also connected to the transverse movement mechanism through the transmission mechanism. After the cylinder 21 drives the telescopic positioning mechanism into the shoe, the telescopic positioning mechanism can move towards the toe of the shoe. The movable end of the cylinder 21 drives the transmission mechanism to trigger, so that the pressure roller 12 applies pressure to the side of the shoe through the pressure strip 13.

[0033] In this embodiment, during operation, the shoe is placed between the two pressure blocks 9, with the shoe opening aligned with the cylinder 21. Then, the movable end of the cylinder 21 extends downward until the telescopic positioning mechanism enters the shoe. Subsequently, the telescopic positioning mechanism begins to move towards the toe of the shoe and performs an unfolding action inside the shoe. Subsequently, the movable end of the cylinder 21 continues to extend downward, so that the telescopic positioning mechanism in the unfolded state applies pressure to the upper two ends of the sole, thereby effectively preventing the toe from warping when the two pressure blocks 9 apply pressure to the shoe. As the movable end of the cylinder 21 continues to extend downward, the transmission mechanism is triggered, which enables the pressure roller 12 to start applying pressure to the side of the shoe through the pressure strip 13. The lateral movement mechanism drives the pressure roller 12 to move along the length direction of the pressure strip 13, performing full roller pressing on the side of the shoe.

[0034] It should be added that, in actual implementation, the two pressure strips 13 can be set with different shapes. That is, the two have a certain curvature on the side facing the shoe to adapt to the curved contour of the shoe side, while the two are set flat on the side away from the shoe. The pressure roller 12 abuts against this side and rolls on this side. Secondly, specifically, four fixing blocks (not labeled in the figure) are fixed on the workbench 1, with two on each side of the shoe. The two ends of the pressure strip 13 are fixedly connected to these two fixing blocks to facilitate the installation of the pressure strip 13. In actual production, the pressure strip 13 is a vulnerable part and needs to be replaced regularly.

[0035] As a further embodiment of the present invention, please refer again. Figure 5 , Figure 6 as well as Figure 10 The worktable 1 is provided with a first mounting groove 101. The opposing drive mechanism includes a first linear drive module 3 installed in the first mounting groove 101 and two transverse seats 4 symmetrically arranged on the first linear drive module 3. The first linear drive module 3 can drive the two transverse seats 4 to move towards each other. The worktable 1 is also symmetrically provided with two guide grooves 103. A fitting block 5 is slidably fitted in each of the two guide grooves 103. The two fitting blocks 5 are fixed to the two transverse seats 4 respectively. The pressure block 9 is connected to the fitting block 5 through an elastic component.

[0036] In this embodiment, it should be noted that the first linear drive module 3 is an application of existing technology, which is based on bidirectional lead screw and servo motor drive to realize the position adjustment of the transverse seat 4 and the fitting block 5 and the pressure application of the shoe after the pressure block 9 contacts the shoe; Secondly, a soft rubber pad is provided in the arc-shaped recess 901 of the pressure block 9 to prevent the pressure block 9 from scratching the shoe surface during the pressure application process.

[0037] As a further embodiment of the present invention, the elastic component includes a guide plate 6 fixedly mounted on the fitting block 5, a telescopic rod 7 slidably fitted with the guide plate 6, and a cylindrical spring 8 located inside the guide plate 6. One end of the cylindrical spring 8 is connected to the inner wall of the guide plate 6, and the other end is connected to a frustum 701 fixedly disposed at the head end of the telescopic rod 7. The tail end of the telescopic rod 7 is fixedly connected to the pressure block 9.

[0038] In this embodiment, the cylinder 21 drives the telescopic positioning mechanism into the shoe, and the telescopic positioning mechanism switches to the unfolded state and applies pressure to both ends of the sole. Then, the first linear drive module 3 works, driving the two transverse seats 4 to move closer to each other. Correspondingly, the pressure block 9 moves toward the shoe. After the pressure block 9 contacts the shoe, as the first linear drive module 3 continues to load, the telescopic rod 7 slides relative to the guide plate 6, and the column spring 8 is gradually compressed. Therefore, under the elastic support of the column spring 8, the two pressure blocks 9 can apply pressure to the heel and toe respectively, promoting adhesion.

[0039] As a further embodiment of the present invention, please refer again. Figure 11 The telescopic positioning mechanism includes a multi-section telescopic structure installed on the movable end of the cylinder 21. When the multi-section telescopic structure is in a retracted state, it can be driven by the cylinder 21 to move down into the shoe. The multi-section telescopic structure includes a guide plate 24 fixed to the movable end of the cylinder 21 and multiple telescopic joints 25 connected to the guide plate 24. The guide plate 24 and the multiple telescopic joints 25 are sequentially and slidably connected in a sealed manner. The end of the guide plate 24 that is in communication with the telescopic joints 25 is provided with a first stop 2402 and a second stop 2504, respectively. The end of the telescopic joint 25 is also provided with a limiting protrusion 2503 that cooperates with the first stop 2402 and the second stop 2504. The inner wall of the telescopic joint 25 is provided with an air hole 2502. The guide plate 24 is provided with an air inlet 2401. When air is pumped into the guide plate 24 through the air inlet 2401, the multiple telescopic joints 25 can be caused to perform an extension action. The bottom of the telescopic joint 25, which is away from the guide plate 24, is also provided with a protrusion 2501, which is flush with the bottom of the guide plate 24.

[0040] Specifically, regarding the process of the multi-section telescopic structure transitioning from a contracted state to an extended state, the air inlet 2401 is connected to an external air pump. After the cylinder 21 drives the contracted multi-section telescopic structure into the shoe, the external air pump operates, pumping air into the guide plate 24. The gas enters the multiple telescopic sections 25 through the air holes 2502. The pumped gas then applies a thrust to the telescopic sections 25, causing them to move outward from the guide plate 24 and perform an extension action. During this process, the limiting protrusion 2503 abuts against the first stop 2402 and the second stop 2504, limiting the extension of the telescopic sections 25. Thus, the guide plate 24 corresponds to the heel area, the protrusion 2501 corresponds to the toe area, and the bottoms of the protrusion 2501 and the guide plate 24 are flush. Under the pressure of the cylinder 21, the multi-section telescopic structure can apply pressure to both ends of the sole, improving the overall flatness of the sole. After the work is completed, the external air pump draws air, which in turn creates negative pressure inside the guide plate 24 and the telescopic joint 25, causing the multiple telescopic joints 25 to retract into the guide plate 24. The multi-section telescopic structure switches from the extended state to the retracted state, so that the moving end of the cylinder 21 can move upward and drive the multi-section telescopic structure to be pulled out of the shoe.

[0041] In this invention, initially, the multi-section telescopic structure remains in a contracted state. The cylinder 21 drives it downward, entering the shoe from the shoe opening. It then begins to unfold inside the shoe, switching to the unfolded state. The protrusion 2401 moves towards the toe. Finally, under the pressure of the cylinder 21, the unfolded multi-section telescopic structure can apply pressure to both ends of the sole, achieving effective positioning of the shoe. This prevents the toe from warping when the pressure block 9 applies pressure to both ends of the shoe, avoiding uneven pressure distribution, local underpressure, or weak adhesion in the key bonding area between the upper and sole, which would seriously affect the strength and consistency of the bonding.

[0042] As a further embodiment of the present invention, please refer again. Figures 6-9 The inner side of the workbench 1 is also provided with a second mounting groove 102. The transverse movement mechanism includes a second linear drive module 10 installed in the second mounting groove 102 and a movable seat 11 provided on the second linear drive module 10. The movable seat 11 is connected to the pressure roller 12 through a telescopic arm assembly, and the telescopic arm assembly is connected to the transmission mechanism.

[0043] It should be noted that the second linear drive module 10 is also an application of existing technology. It is based on a unidirectional lead screw and servo motor drive, which is used to drive the movable seat 11 to move along the length direction of the second mounting groove 102 in the second mounting groove 102, so as to drive the pressure roller 12 to roll along the side of the pressure strip 13 away from the shoe.

[0044] As a further embodiment of the present invention, the telescopic arm assembly includes a first connecting arm 14 fixed to the movable seat 11 and a second connecting arm 15 slidably fitted with the first connecting arm 14. The pressure roller 12 is rotatably mounted on the end of the second connecting arm 15 away from the movable seat 11, and the second connecting arm 15 is connected to the transmission mechanism.

[0045] In this embodiment, specifically, when the transmission mechanism is triggered, it causes the second connecting arm 15 to slide relative to the first connecting arm 14. That is, the second connecting arm 15 can drive the pressure roller 12 to move toward the pressure strip 13, so that the pressure roller 12 can apply pressure to the side of the shoe through the pressure strip 13. Subsequently, the second linear drive module 10 works, which can drive the movable seat 11 to move along the length direction of the second mounting groove 102 in the second mounting groove 102. The movable seat 11 then drives the pressure roller 12 to roll on the side of the pressure strip 13 away from the shoe through the first connecting arm 14 and the second connecting arm 15.

[0046] As a further embodiment of the present invention, please refer again. Figure 8 , Figure 9 as well as Figure 11 The transmission mechanism includes a follower structure mounted on the side plate 2. The follower structure is connected to the second connecting arm 15, and a sliding engagement assembly is provided between the follower structure and the movable end of the cylinder 21. The follower structure includes a guide rail 18 fixed on the side plate 2, a slider 19 slidably fitted on the guide rail 18, and a cross arm 17 fixed to the slider 19. A sleeve 16 is fixed on the second connecting arm 15. The sleeve 16 is adapted to the cross arm 17, and the cross arm 17 passes through the sleeve 16 and is slidably connected to the sleeve 16. The sliding engagement assembly includes a driven plate 20 fixed to the slider 19 and a follower arm 22 fixed to the movable end of the cylinder 21. A drive column 23 is fixed to one end of the follower arm 22 facing the driven plate 20, and the driven plate 20 is provided with a groove adapted to the drive column 23. The drive column 23 passes through the groove and is slidably connected to the driven plate 20. The groove includes a first groove segment 2001 and a second groove segment 2002 connected to each other. The first groove segment 2001 is vertically arranged, and the second groove segment 2002 is inclined. It should be emphasized that when the cylinder 21 drives the drive column 23 to move downward, and the drive column 23 moves in the second groove 2002, it can cause the driven plate 20 to drive the slider 19 to slide toward the midpoint of the guide rail 18.

[0047] In this embodiment, as the movable end of the cylinder 21 extends downward, the multi-section telescopic structure enters the shoe. Before switching to the unfolded state, the drive column 23 moves downward along the first groove 2001. After the multi-section telescopic structure switches to the unfolded state, the movable end of the cylinder 21 continues to extend downward so that the multi-section telescopic structure in the unfolded state applies pressure to both ends of the sole for positioning. During this process, the drive column 23 moves in the second groove 2002 and slides with the driven plate 20, causing the driven plate 20 to drive the slider 19 to slide toward the midpoint of the guide rail 18. Correspondingly, the slider 19 drives the second connecting arm 15 away from the movable seat 11 through the cross arm 17 and the sleeve plate 16, so that the pressure roller 12 can apply pressure to the side of the shoe through the pressure strip 13. Subsequently, during the operation of the second linear drive module 10, the sleeve plate 16 slides on the cross arm 17.

[0048] To address this, the present invention provides a pressure roller 12 on each side of the shoe. The pressure roller 12 applies pressure to the side of the shoe through a pressure strip 13. Driven by a lateral movement mechanism, the pressure roller 12 can roll along the side of the pressure strip 13 away from the shoe, thereby achieving comprehensive flexible compression of the side of the shoe and promoting bonding. Compared with the compression method using an air-filled inflatable bladder, this effectively improves the fullness of compression, avoids the problem of uneven pressure distribution caused by the expansion characteristics of the air bladder, improves the uniformity of pressure transmission on the side of the shoe, and avoids insufficient pressure at the edges, thereby reducing the stability and reliability of the overall pressing quality.

[0049] A shoe-making compaction method, employing the aforementioned shoe-making compaction machine based on flexible extrusion, includes the following steps: Step 1: Place the shoe between the two pressure blocks 9. The moving end of the cylinder 21 extends downward until the multi-section telescopic structure in the contracted state enters the shoe and performs the unfolding action inside the shoe. Step two, the moving end of cylinder 21 continues to move, so that the multi-section telescopic structure in the unfolded state applies pressure to the two ends of the shoe sole for positioning. The transmission mechanism is triggered, so that the pressure roller 12 applies pressure to the side of the shoe through the pressure strip 13. Step 3: The opposing drive mechanism works to drive the two pressure blocks 9 to move closer to each other. The two pressure blocks 9 apply pressure to the toe and heel of the shoe respectively. The lateral movement mechanism works to drive the pressure roller 12 to roll along the side of the pressure strip 13 away from the shoe and to perform flexible compression on the side of the shoe. Step 4: Once the process is complete, remove the shoes from workbench 1.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
