Description

Technical Field

[0001] This application relates to the field of bottom pressing machines, and more particularly to a transfer mechanism and a bottom pressing machine. Background Technology

[0002] The transfer mechanism in existing bottom pressing machines is generally a three-axis robot, such as the one described in the instruction manual with publication number CN121570023A. Figures 5-8 As shown, the fixture translates along the XYZ axes to move the shoe from one workstation to another.

[0003] The inventor discovered in daily production that when a transfer mechanism with a clamp translating along the XYZ three axes is used to transfer shoes, the transfer path is long, the time is long, and the production efficiency of the sole pressing machine is affected. Therefore, this application was designed. Summary of the Invention

[0004] In order to shorten the shoe transfer path and improve the transfer efficiency and the production efficiency of the sole pressing machine, this application provides a transfer mechanism and a sole pressing machine.

[0005] In one aspect of this disclosure, a transfer mechanism is provided, including a swing arm mechanism and a clamp. The swing arm mechanism includes a drive component and a rocker arm that is throttledly connected to the drive component. The rocker arm is hinged to the upper end of the clamp. The drive component drives the rocker arm to swing, causing the clamp to move around the swing center of the rocker arm. During the movement, the upper and lower ends of the clamp remain relatively stationary. The drive component is connected to a lateral movement device, which is configured to drive the rocker arm to move laterally on the rocker arm swing plane.

[0006] By adopting the above technical solution, the transfer mechanism can drive the clamp to move in a curved motion with an arc trajectory on the vertical plane, transferring shoes from one workstation to another. During the transfer process, the clamp maintains a vertical and stable posture without swaying, ensuring smooth shoe transfer. The transfer path is significantly shorter than that of traditional XYZ three-axis transfer mechanisms, and the transfer speed is fast and the time is short, effectively improving transfer efficiency and the production efficiency of the sole pressing machine. In addition, while the drive component drives the rocker arm to swing and move the clamp around the swing center of the rocker arm, the lateral movement device drives the rocker arm to move laterally on the swing plane of the rocker arm, thereby increasing the transfer range of the clamp and meeting the needs of more models of sole pressing machines.

[0007] Preferably, the swing arm mechanism further includes: The mounting component has a horizontally sliding frame mounted on it, and a vertically sliding frame is mounted on the horizontally sliding frame. The clamp is connected to the vertically sliding frame.

[0008] By adopting the above technical solution, the clamps can maintain a vertical and stable posture throughout the transfer process without swaying, thus ensuring that the shoes are transferred stably.

[0009] Preferably, the rocker arm and the clamp are hinged together by a wheel axle. The rocker arm mechanism also includes a pair of transmission wheels with equal diameters and a flexible member tightly fitted on the pair of transmission wheels. One of the transmission wheels is coaxial with the rocker arm swing center and is configured to remain fixed during the rocker arm swing. The other transmission wheel is coaxially and fixedly connected to the wheel axle. The clamp is fixedly connected to the wheel axle.

[0010] By adopting the above technical solution, the clamps can maintain a vertical and stable posture throughout the transfer process without swaying, thus ensuring that the shoes are transferred stably.

[0011] Preferably, the driving component is fixedly connected to a connecting component, and multiple spaced and parallel wheel axles are rotatably mounted on the connecting component. There are multiple rocker arms, which are spaced and parallel and are all hinged to the clamp. Each rocker arm is fixedly connected to one wheel axle, and the multiple wheel axles are connected to the driving component for transmission.

[0012] By adopting the above technical solution, the clamps can maintain a vertical and stable posture throughout the transfer process without swaying, thus ensuring that the shoes are transferred stably.

[0013] Preferably, the clamps are a pair and spaced apart. The pair of clamps are hinged to the same connecting rod, and the movement of one clamp around the swing center of the rocker arm drives the other clamp to move synchronously through the connecting rod.

[0014] By adopting the above technical solution, the two clamps can move synchronously, picking up the shoes and transferring them to the bottom pressing module, and removing the shoes from the bottom pressing module after they have been pressed are done simultaneously.

[0015] Preferably, the clamp includes a frame and a push-pull component mounted on the frame. A movable block is installed at the telescopic end of the push-pull component. Each end of the movable block is hinged with a clamping arm 1. A clamping arm 2 is hinged to the clamping arm 1. The middle part of the clamping arm 2 bends towards the frame and is hinged to the frame. A clamping arm 3 is hinged to the end of the clamping arm 2 away from the clamping arm 1. The end of the clamping arm 3 near the clamping arm 2 is also hinged to the frame via a connecting rod. The push-pull component drives the movable block to move, and through the clamping arm 1, clamping arm 2, and connecting rod, the pair of clamping arms 3 move closer to each other or further away from each other.

[0016] By adopting the above technical solution, a pair of clamping arms move closer to each other to clamp the shoe. Compared with the traditional figure-eight clamp, this clamping method has a more stable clamping force, the shoe is less likely to fall off, and it can clamp various shoe types, making it widely applicable.

[0017] In another aspect of this disclosure, a wall-mounted sole pressing machine is provided, including a main frame and an upper pressing rod assembly and a lower pressing module mounted on the main frame, and also including the aforementioned transfer mechanism, which is located next to the upper pressing rod assembly. The swing arm mechanism is configured to drive the clamp to pick up the shoe and transfer the shoe to the lower pressing module or drive the clamp to remove the shoe that has been pressed in the lower pressing module.

[0018] By adopting the above technical solution, the transfer mechanism drives the clamp to make curved motion on the vertical plane to transfer the shoe from one workstation to another. During the transfer process, the clamp always maintains a vertical and stable posture without swaying, the shoe is transferred smoothly, the transfer path is much smaller than that of the traditional XYZ three-axis transfer mechanism, and the transfer speed is fast and the time is short, which effectively improves the production efficiency of the sole pressing machine.

[0019] In another aspect of this disclosure, a wall-mounted sole pressing machine is provided, including a main frame and an upper pressing rod assembly and a lower pressing module mounted on the main frame. It also includes a transfer mechanism located next to the upper pressing rod assembly. The swing arm mechanism is configured to drive one of the clamps to pick up a shoe and transfer the shoe to the lower pressing module, while simultaneously driving another clamp to remove the pressed shoe from the lower pressing module.

[0020] By adopting the above technical solution, the transfer mechanism drives two clamps to make curved motions on the vertical plane to pick up shoes and transfer them to the bottom pressing module. At the same time, it drives the shoes that have been pressed in the bottom pressing module to be removed. The transfer path is much smaller than that of the traditional XYZ three-axis transfer mechanism, and the transfer speed is fast and the time is short, which effectively improves the production efficiency of the bottom pressing machine.

[0021] Preferably, the lower pressing module has a pair of tightening mechanisms, which are driven by cylinders to move closer or further apart. The wall-mounted pressing machine also includes a gas-saving module, which includes: A gas storage device 1, wherein the air inlet end of the gas storage device 1 is connected to a booster device, the air inlet end of the booster device is connected to an air supply pipe 1, the air outlet end of the gas storage device 1 is connected to an air inlet pipe 1, a control valve 1 is provided on the air inlet pipe 1, and the air outlet end of the air inlet pipe 1 is connected to the air inlet end of the cylinder. The second gas storage device has an outlet end connected to an inlet pipe and a supply pipe. The inlet pipe is equipped with a control valve. The outlet end of the inlet pipe is connected to the inlet end of the cylinder. The supply pipe is connected to the inlet end of the booster device. The supply pipe is equipped with a control valve. The inlet end of the gas storage device is connected to an exhaust pipe. The exhaust pipe is equipped with a control valve. The inlet end of the exhaust pipe is connected to the exhaust end of the cylinder. A pressure detection device is installed on gas storage device one and gas storage device two; The gas pressure supplied to the cylinder through the first intake pipe is greater than the gas pressure supplied to the cylinder through the second intake pipe.

[0022] By adopting the above technical solution, the gas supplied by the external air source through the air supply pipe is pressurized by the pressurizing device to form a high-pressure gas source, which is stored in the air storage device. The high-pressure gas is then supplied to the cylinder through the air intake pipe. At the same time, the gas recovered from the exhaust pipe is stored in the air storage device and then supplied to the cylinder again through the air intake pipe. This reduces the amount of external air source used, thereby reducing the cost of shoe sole pressing.

[0023] In another aspect of this disclosure, a bottomless molding press is provided, including the aforementioned transfer mechanism.

[0024] By adopting the above technical solution, the transfer mechanism drives the clamp to make curved motion on the vertical plane to transfer the shoe from one workstation to another. During the transfer process, the clamp always maintains a vertical and stable posture without swaying, the shoe is transferred smoothly, the transfer path is much smaller than that of the traditional XYZ three-axis transfer mechanism, and the transfer speed is fast and the time is short, which effectively improves the production efficiency of the sole pressing machine.

[0025] Beneficial technical effects: The transfer mechanism of this application can drive the clamp to make curved motion in the vertical plane to transfer the shoe from one workstation to another. The transfer path is much smaller than that of the traditional XYZ three-axis transfer mechanism. Moreover, the transfer speed is fast and the time is short, which effectively improves the transfer efficiency and the production efficiency of the sole pressing machine. Attached Figure Description

[0043] The following is in conjunction with the appendix Figures 1-13 This application will be described in further detail.

[0044] In one aspect of this disclosure, a transfer mechanism is provided, such as Figure 1 and Figure 2 As shown, the transfer mechanism includes a swing arm mechanism 26 and a clamp 27. The clamp 27 is used to hold the shoe. The swing arm mechanism 26 includes a drive component 263 and a rocker arm 264 that is pulsatorically connected to the drive component 263. The rocker arm 264 is hinged to the upper end of the clamp 27. The drive component 263 drives the rocker arm 264 to swing, causing the clamp 27 to move around the swing center of the rocker arm 264. During the movement, the upper and lower ends of the clamp 27 remain relatively stationary.

[0045] Optional, such as Figure 1 and Figure 2 As shown, one end of the rocker arm 264 is connected to the drive component 263, and the other end is hinged to the upper end of the clamp 27. The drive component 263 is used to drive the rocker arm 264 to rotate and swing. Commonly, the drive component 263 is a motor, motor, etc.

[0046] The rocker arm 264 is hinged to the upper end of the clamp 27. Therefore, the rocker arm 264 swings and drives the clamp 27 to make a curved motion around the swing center of the rocker arm 264 with a circular trajectory. The clamp 27 always remains vertical and does not swing during the curved motion. That is, the upper and lower ends of the clamp 27 remain relatively stationary during the movement.

[0047] By adopting the above technical solution, the transfer mechanism can drive the clamp 27 to make a curved motion with an arc trajectory on the vertical plane to transfer the shoe from one workstation to another. During the transfer process, the clamp 27 always maintains a vertical and stable posture without swaying, and the shoe is transferred smoothly. The transfer path is much smaller than that of the traditional XYZ three-axis transfer mechanism. Moreover, when moving in a curved motion, the moving speed of the clamp 27 can be designed to be faster than that of the XYZ three-axis transfer mechanism, so the time is shorter, significantly improving the shoe transfer efficiency and effectively improving the production efficiency of the sole pressing machine.

[0048] In this embodiment of the disclosure, the clamp 27 remains vertical and does not oscillate during the curved motion by means of the following: Figure 7 As shown, the swing arm mechanism 26 further includes: Mounting component 262 has a horizontally slidable horizontal slide 266 mounted on it, and a vertical slide 265 is vertically slidable on the horizontal slide 266. The clamp 27 is connected to the vertical slide 265. This design ensures that the clamp maintains a vertical and stable posture during the transfer process, preventing swaying and guaranteeing the stable transfer of the shoe.

[0049] Correspondingly, besides the design where the rocker arm 264 is hinged to the upper end of the clamp 27, the vertical slide 265 can also be hinged to the rocker arm 264, such as... Figure 7 As shown.

[0050] Of course, in other embodiments, the clamp 27 can also remain vertical and not swing during the curved motion in the following three ways.

[0051] Method 1: For example Figure 2 As shown, the rocker arm 264 and the clamp 27 are hinged together by a wheel axle 2615. The rocker arm mechanism 26 also includes a pair of transmission wheels with equal diameters and a flexible member tightly fitted on the pair of transmission wheels. One of the transmission wheels is coaxial with the swing center of the rocker arm 264 and is configured to remain fixed during the swing of the rocker arm 264. The other transmission wheel is coaxially and fixedly connected to the wheel axle 2615. The clamp 27 is fixedly connected to the wheel axle 2615.

[0052] By adopting the above technical solution, the clamp 27 can always maintain a vertical and stable posture during the transfer process, without swinging, thus ensuring that the shoes are transferred stably.

[0053] Specifically, a pair of drive wheels can be Figure 2 The pulley 2612 and pulley 2613 shown in the diagram can also be... Figure 14 The sprocket 2618 shown in the diagram has a flexible element of timing belt 2614 when the drive wheel is a pulley, and a flexible element of timing chain 2619 when the drive wheel is sprocket 2618. Figure 2The first pulley 2612 and the connecting part 267 are fixedly connected. When the rocker arm 264 swings, the first pulley 2612 does not rotate, thus driving the second pulley 2613 to rotate through the synchronous belt 2614. The rotation of the second pulley 2613 drives the clamp 27 to rotate synchronously around the wheel shaft 2615 to counteract the swing of the rocker arm 264. In this way, the clamp 27 can always maintain a stable posture during the swing of the rocker arm 264. The clamp 27 is always vertical, and the upper and lower ends of the clamp 27 remain relatively stationary during the movement.

[0054] Method 2: For example Figure 14 As shown, the driving component 263 is fixedly connected to a connecting component 267. Multiple spaced and parallel axles 2617 are rotatably mounted on the connecting component 267. Multiple rocker arms 264 are also spaced and parallel, and each is hinged to the clamp 27. Each rocker arm 264 is fixedly connected to one axle 2617, and the multiple axles 2617 are connected to the driving component 263 via a transmission connection. The driving component 263 drives the multiple axles 2617 to rotate, which in turn drives the multiple rocker arms 264 to swing. The multiple rocker arms 264 swing synchronously, ensuring that the clamp 27 maintains a vertical and stable posture during the transfer process, preventing swaying and ensuring the shoes are transferred stably.

[0055] To facilitate the hinged connection of multiple rocker arms 264 to the clamp 27, multiple rocker arms 264 can be hinged together to the synchronizing rod 2616. The clamp 27 is installed at the lower end of the synchronizing rod 2616. Figure 14 As shown.

[0056] In practical implementation, either a drive component 263 can be configured for each wheel axle 2617, or... Figure 14 As shown, a sprocket 2618 is coaxially fixed on each axle 2617, and multiple sprockets 2618 are connected by a synchronous chain 2619. Thus, a single drive unit 263 can drive multiple axles 2617 to rotate synchronously.

[0057] Of course, the sprocket 2618 on each axle 2617 can also be replaced with Figure 2 The pulley shown has the synchronous chain 2619 replaced with... Figure 2 The synchronous belt shown is 2614.

[0058] Method 3: For example Figure 15As shown, the rocker arm 264 and the clamp 27 are hinged via axle 2615. The rocker arm mechanism 26 also includes a bevel gear 2620, a bevel gear 2621, axle 2622, and a pair of bevel gears 2623 coaxially fixedly connected to axle 2622. Axle 2622 is rotatably mounted on the rocker arm 264. One bevel gear 2623 meshes with bevel gear 2620, and the other bevel gear 2623 meshes with bevel gear 2621. The bevel gear 2620 is coaxial with the swing center of the rocker arm 264 and is configured to remain fixed during the swing of the rocker arm 264. For example, bevel gear 2620 is fixedly connected to the connecting component 267, so that the driving component 263 drives the rocker arm 264 to rotate around bevel gear 2620. The bevel gear 2621 is coaxially fixedly connected to axle 2615, and the clamp 27 is fixedly connected to axle 2615. The swing arm 264 rotates around the bevel gear 2620, which drives the bevel gear 2623 and the axle 2622 to rotate, which in turn drives the axle 2615 to rotate to counteract the swing of the swing arm 264, so that the clamp 27 always maintains a vertical posture during the rotation of the swing arm 264.

[0059] The transfer mechanism described in the foregoing embodiment has only one clamp 27. In other embodiments, the transfer mechanism may have a pair of clamps 27, such as... Figure 7 As shown, the rocker arm 264 is rotatably connected to the mounting component 262. Each clamp 27 has a pair, spaced apart. The pair of clamps 27 are hinged to the same connecting rod 261. One clamp 27 moves around the swing center of the rocker arm 264, driving the other clamp 27 to move synchronously via the connecting rod 261. This design allows the two clamps 27 to move synchronously. While one clamp 27 picks up a shoe and moves it to the bottom-pressing module 22, the other clamp 27 removes the shoe from the bottom-pressing module 22 after it has been pressed. Both actions occur simultaneously, and at this time, only one drive component 263 is needed to drive the pair of rocker arms to swing.

[0060] When the transfer mechanism described in the foregoing embodiment has only one clamp 27, two transfer mechanisms can be set in the wall-mounted bottom pressing machine. One transfer mechanism is used to pick up the shoes and transfer them to the bottom pressing module 22, and the other transfer mechanism is used to remove the shoes that have been pressed in the bottom pressing module 22.

[0061] Furthermore, such as Figures 1-2 , Figures 7-9As shown, the driving component 263 is connected to a lateral movement device. This lateral movement device is configured to drive the rocker arm 264 to move laterally on the rocker arm 264's swing plane. The rocker arm 264's swing plane is the plane on which the rocker arm 264 always swings when the driving component 263 drives it to swing. While the driving component 263 drives the rocker arm 264 to swing, causing the clamp 27 to move in an arc-shaped curve around the rocker arm 264's swing center, the lateral movement device drives the rocker arm 264 to move laterally on the rocker arm 264's swing plane, thus moving the clamp 27 laterally. This increases the range of shoe transfer by the clamp 27, meeting the needs of more types of sole pressing machines.

[0062] As an example, such as Figures 1-2 As shown, the lateral movement device includes: Mounting plate 260, on which drive element 2611 is mounted; Connecting component 267 is connected to driving component 263 and slidably connected to mounting plate 260, for example... Figure 1 and Figure 2 The lower end of the connecting component 267 shown is fixedly connected to the driving component 263. The upper end of the connecting component 267 is fixedly provided with a top slide 268. The lower surface of the mounting plate 260 is fixedly provided with a slide rail 269. The slide rail 269 and the top slide 268 are slidably connected. Rack 2610 is fixedly connected to connecting component 267 and meshes with drive element 2611. Drive element 2611 drives rack 2610 to move, causing connecting component 267 and drive component 263 to move laterally. Commonly, drive element 2611 is a motor and gears, such as... Figure 2 As shown, the gear meshes with the rack 2610.

[0063] In other embodiments, such as Figures 8-9 As shown, the lateral movement device includes: Mounting plate 260, on which drive element 2611 is mounted; Connecting component 267 is connected to mounting component 262, driving component 263 is mounted on mounting component 262, and connecting component 267 is slidably connected to mounting plate 260, for example... Figure 9 The lower end of the connecting component 267 shown is fixedly connected to the mounting component 262. The upper end of the connecting component 267 is fixedly provided with a top slide 268. The lower surface of the mounting plate 260 is fixedly provided with a slide rail 269. The slide rail 269 and the top slide 268 are slidably connected. Rack 2610 is fixedly connected to connecting component 267 and meshes with drive element 2611. Drive element 2611 drives rack 2610 to move, causing connecting component 267 and drive component 263 to move laterally. Commonly, drive element 2611 is a motor and gears, such as... Figure 8 As shown, the gear meshes with the rack 2610.

[0064] By adopting the above-mentioned transverse movement device, the rocker arm 264 can be moved laterally on the swing plane of the rocker arm 264. Moreover, this transverse movement device is also easy to install in a wall-mounted bottom pressing machine.

[0065] In this embodiment, the clamp 27 is preferably a parallel clamp. Compared with the traditional figure-eight clamp, the parallel clamp has a more stable clamping force, making it less likely for the shoe 7 to fall off. It can clamp various shoe types and has a wide range of applications.

[0066] Specifically, such as Figure 3 As shown, the parallel clamp includes a frame 272 and a push-pull component 271 mounted on the frame 272. A movable block 273 is installed at the telescopic end of the push-pull component 271. A clamping arm 274 is hinged to each of the left and right ends of the movable block 273. A clamping arm 275 is hinged to the end of the clamping arm 274 away from the movable block 273. The middle part of the clamping arm 275 bends towards the frame 272 and is hinged to the frame 272. Of course, in other embodiments, the middle part of the clamping arm 275 can also be hinged to a fixed block 276, and the fixed block 276 is fixedly connected to the frame 272.

[0067] continue Figure 3 As shown, one end of clamping arm 275 is hinged to clamping arm 274, and the other end of clamping arm 275 is hinged to clamping arm 278. The upper end of clamping arm 278 is provided with a crossbeam 2781. The two transverse ends of the crossbeam 2781 are respectively hinged to clamping arm 275 and connecting rod 277. Clamping arm 275 is located at the end of the crossbeam 2781 away from the frame 272. The end of the connecting rod 277 away from the crossbeam 2781 is hinged to the frame 272. The lower end of clamping arm 278 is provided with a clamping block 270 facing the side of another clamping arm 278. The clamping block 270 is fixedly installed on the movable seat 279. The movable seat 279 is hinged to clamping arm 278 through a limiting post 2710.

[0068] When the parallel clamp is working, with Figure 3 For example, the push-pull component 271 drives the movable block 273 to rise and fall, which in turn drives the first clamping arm 274, the second clamping arm 275, and the connecting rod 277 to swing. The swinging of the first clamping arm 274, the second clamping arm 275, and the connecting rod 277 causes a pair of third clamping arms 278 to move diagonally upwards and away from each other or diagonally downwards and closer to each other. During the process of the pair of third clamping arms 278 moving away from each other or closer to each other, the third clamping arms 278 only translate and do not swing. The clamping surface 2711 of the clamping block 270 on the pair of third clamping arms 278 always remains vertical. With this design, the clamping surface 2711 of the parallel clamp is vertical at any height position, which can ensure maximum contact surface when clamping different shoe types, and the clamping is stable and reliable.

[0069] Furthermore, such as Figure 3 As shown, multiple clamping blocks 270 are hinged to the lower side of the clamping arm 278. This design can adapt to the sides of various shoe shapes and make multiple contacts with the sides of the shoe, so that various shoe shapes can be firmly clamped with excellent clamping effect.

[0070] In another aspect of the embodiments of this disclosure, a wall-mounted bottom pressing machine is provided, such as Figures 4-6 As shown, the wall-mounted bottom pressing machine includes a main frame 25 and an upper pressing rod assembly 23, a lower pressing module 22, and a transverse movement mechanism 24 mounted on the main frame 25. The transverse movement mechanism 24 is connected to the upper pressing rod assembly 23 and is used to drive the upper pressing rod assembly 23 to move laterally, so that the upper pressing rod assembly 23 can move to directly above the lower pressing module 22 and move away from directly above the lower pressing module 22.

[0071] It should be noted that the structure and function of the upper pressure rod assembly 23, the lower pressure bottom module 22, and the transverse movement mechanism 24 have been disclosed in the patent with publication number CN121570023A, and will not be repeated here.

[0072] like Figures 4-6 As shown, the wall-mounted bottom pressing machine also includes Figures 1-2 or Figure 14 The transfer mechanism is mounted on the main frame 25 and located next to the upper pressure rod assembly 23. The swing arm mechanism 26 is configured to drive the clamp 27 to pick up the shoe and transfer it to the lower pressure module 22, or to drive the clamp 27 to remove the shoe after it has been pressed in the lower pressure module 22. With two transfer mechanisms, the operations of picking up the shoe and transferring it to the lower pressure module 22 and driving the clamp 27 to remove the shoe after it has been pressed in the lower pressure module 22 can be performed simultaneously.

[0073] The transfer mechanism can be fixedly connected to the main frame 25 via the mounting plate 260, or it can be slidably connected to the main frame 25. When the transfer mechanism is fixedly connected to the main frame 25, the swing arm mechanism 26 can drive the clamp 27 to move directly above the bottom pressing module 22 and away from directly above the bottom pressing module 22. The installation position of the transfer mechanism is as follows: Figure 6 As shown.

[0074] When the transfer mechanism is slidably connected to the main frame 25, the transfer mechanism is connected to the transverse mechanism 24. The transverse mechanism 24 drives the clamp 27 to move directly above the bottom pressing module 22 and away from the bottom pressing module 22, so as to cooperate with the upper pressing rod assembly 23 to complete the shoe pressing operation.

[0075] Of course, in other embodiments, the wall-mounted bottom pressing machine can also be as follows: Figure 10 and Figure 11As shown, it includes a main frame 25 and an upper pressure rod assembly 23, a lower pressure bottom module 22, and a transverse movement mechanism 24 mounted on the main frame 25. The transverse movement mechanism 24 is connected to the upper pressure rod assembly 23 and is used to drive the upper pressure rod assembly 23 to move laterally.

[0076] like Figure 10 and Figure 11 As shown, the wall-mounted bottom pressing machine also includes Figures 7-9 The transfer mechanism is installed on the main frame 25 and located next to the upper pressure rod assembly 23. The swing arm mechanism 26 is configured to drive one of the clamps 27 to pick up the shoe and transfer the shoe to the lower pressure module 22, while driving the other clamp 27 to take away the shoe that has been pressed in the lower pressure module 22.

[0077] Similarly to the aforementioned embodiments, the transfer mechanism can be fixedly connected to the main frame 25 via the mounting plate 260 or slidably connected to the main frame 25. When the transfer mechanism is slidably connected to the main frame 25, the transfer mechanism is connected to the transverse mechanism 24. The transverse mechanism 24 drives the clamp 27 to move directly above the lower pressing module 22 and away from the lower pressing module 22, so as to cooperate with the upper pressing rod assembly 23 to complete the shoe pressing operation.

[0078] When the transfer mechanism is fixedly connected to the main frame 25, the swing arm mechanism 26 can drive the clamp 27 to move directly above the lower pressing module 22 and away from directly above the lower pressing module 22. At this time, it should be... Figures 7-9 The connecting rod 261 is positioned diagonally above the clamp 27 to avoid affecting the lateral movement of the upper pressure rod assembly 23.

[0079] This embodiment of the wall-mounted sole pressing machine is equipped with a transfer mechanism, which enables the clamp 27 to move in a curved motion on a vertical plane to transfer shoes from one workstation to another, such as transferring shoes to the shoe placement area or removing shoes from the shoe placement area, thereby realizing unmanned automated assembly line sole pressing operations. During the transfer process, the clamp 27 always maintains a vertical and stable posture without swaying, the shoes are transferred smoothly, the transfer path is significantly shorter than that of traditional XYZ three-axis transfer mechanisms, and the transfer speed is fast and the time is short, effectively improving the production efficiency of the sole pressing machine.

[0080] In this embodiment, the lower pressing module 22 has a pair of clamping mechanisms, which are driven by a linear driver or a motor to move closer to or further away from each other.

[0081] The linear actuator includes a pneumatic cylinder 221, a hydraulic cylinder, an electric cylinder, etc.

[0082] Specifically, Figures 4-6 , Figures 10-11 The lower pressure module 22 shown employs a linear actuator to drive the clamping mechanism. In another embodiment, Figure 12 The wall-mounted bottom pressing machine shown uses a motor-driven tightening mechanism for its bottom pressing module 22.

[0083] It should be noted that, Figures 1-2 , Figure 14 The transfer mechanism can also be installed on Figures 10-12 Similarly, in the wall-mounted bottom press shown, Figures 7-9 The transfer mechanism can also be installed on Figures 4-6 The wall-mounted bottom press shown.

[0084] The pair of clamping mechanisms of the current pressing module 22 are driven by cylinder 221 to move closer or further apart. The wall-mounted pressing machine also includes a gas-saving module 28, such as... Figure 13 As shown, the throttle module 28 includes: The system includes a first gas storage device 281, a second gas storage device 286, and a pressure detection device 293. The inlet of the first gas storage device 281 is connected to a booster device 282, and the inlet of the booster device 282 is connected to a first gas supply pipe 283. Gas supplied from an external gas source enters the booster device 282 through the first gas supply pipe 283. The booster device 282 pressurizes the gas to form high-pressure gas, which is stored in the first gas storage device 281. This system satisfies the pressure requirements of the wall-mounted press machine while ensuring a stable and reliable gas pressure supply, thus guaranteeing the normal operation of the press machine. Even if the external gas source is suddenly interrupted, the high-pressure gas stored in the first gas storage device 281 can still supply the wall-mounted press machine for a considerable period, sufficient to wait for the external gas source to be repaired and restored, without disrupting production.

[0085] like Figure 13 As shown, the outlet of the gas storage device 281 is connected to the inlet pipe 284. The inlet pipe 284 is equipped with a control valve 289. The outlet of the inlet pipe 284 is connected to the inlet of the cylinder 221 for filling the cylinder 221 with high-pressure gas. The control valve 289 is used to control the opening and closing of the inlet pipe 284.

[0086] like Figure 13 As shown, the outlet of the gas storage device 286 is connected to the inlet pipe 287 and the supply pipe 292. The inlet pipe 287 is equipped with a control valve 288. The outlet of the inlet pipe 287 is connected to the inlet of the cylinder 221 for filling the cylinder 221 with low-pressure recovery gas. The control valve 288 is used to control the opening and closing of the inlet pipe 287.

[0087] like Figure 13As shown, the second gas supply pipe 292 is connected to the air inlet of the booster device 282. The second gas supply pipe 292 is equipped with a fourth control valve 294. When the second gas storage device 286 stores a large amount of recovered gas and the gas pressure is high, in order to ensure the safety of the second gas storage device 286, the fourth control valve 294 can be opened to allow the gas in the second gas storage device 286 to enter the booster device 282. After the gas is further pressurized, it is stored in the first gas storage device 281. After the gas pressure in the second gas storage device 286 drops to the normal range, the fourth control valve 294 is closed, and the recovered gas can continue to be stored in the second gas storage device 286.

[0088] like Figure 13 As shown, the air inlet of the second air storage device 286 is connected to an exhaust pipe 285. A control valve 290 is installed on the exhaust pipe 285. The air inlet of the exhaust pipe 285 is connected to the exhaust end of the cylinder 221, used to recover the high-pressure gas discharged from the cylinder 221. When the sole of one shoe 7 is pressed down and the high-pressure gas in the cylinder 221 needs to be discharged, the control valve 290 is opened, allowing the high-pressure gas discharged from the cylinder 221 to enter the second air storage device 286 through the exhaust pipe 285.

[0089] Furthermore, such as Figure 13 As shown, the control valve 290 has an exhaust port connected to the outside, and the exhaust port is equipped with a silencer 291. This design allows the control valve 290 to cut off the gas supply to the gas storage device 286 when the gas pressure inside the storage device 286 is high, instead directly discharging the remaining gas recovered by the exhaust pipe 285 into the atmosphere to protect the safety of the gas storage device 286. The silencer 291 reduces exhaust noise.

[0090] In this embodiment, as Figure 13 As shown, both the first gas storage device 281 and the second gas storage device 286 are equipped with a gas pressure detection device 293 to detect the gas pressure in the first gas storage device 281 and the second gas storage device 286 in real time, thereby providing a reference for subsequent actions to control the gas pressure stability and avoiding excessively high gas pressure in the first gas storage device 281 and the second gas storage device 286 from affecting gas safety.

[0091] As can be seen, the throttle module 28 in this embodiment is equipped with two gas storage devices. Gas storage device one 281 is used to store a stable high-pressure gas source, and gas storage device two 286 is used to store recovered gas for secondary use. Specifically, the gas supplied by the external gas source through gas supply pipe one 283 is pressurized by the booster device 282 to form a high-pressure gas source, which is stored in gas storage device one 281. The high-pressure gas is then supplied to cylinder 221 through air intake pipe one 284. At the same time, gas storage device two 286 stores the gas recovered from exhaust pipe 285, and then supplies it back to cylinder 221 through air intake pipe two 287. In this way, the amount of external gas used can be reduced, thereby reducing the cost of the shoe sole 7.

[0092] In another aspect of this disclosure, a sole-forming moldless pressing machine is provided. As is known, a sole-forming moldless pressing machine includes a lower mold and an upper mold. The upper mold includes a pressure cap and a lifting device connecting the pressure cap. The lifting device drives the pressure cap to rise and fall, and the pressure cap descends to cooperate with the lower mold in completing the sole-forming operation of the shoe. The lower mold includes a lower mold body and a lower bladder. The upper surface of the lower mold body is recessed inward to form a mold cavity. An elastic lower bladder is disposed in the mold cavity, and the lower bladder seals the mold cavity. The lower bladder extends downward to form a shoe-placement area. Gas or liquid is injected into the mold cavity to compress the lower bladder, thereby causing the lower bladder to compress the shoe in the shoe-placement area. This is the working principle of the sole-forming moldless pressing machine.

[0093] This embodiment of the sole-forming machine adds the aforementioned transfer mechanism to enable the transfer mechanism to drive the clamp to perform curved motion in a vertical plane, transferring shoes from one workstation to another, such as transferring shoes to the shoe placement area or removing shoes from the shoe placement area, thereby achieving unmanned automated assembly line sole-forming operations. During the transfer process, the clamp maintains a vertically stable posture without swaying, the shoes are transferred smoothly, the transfer path is significantly shorter than that of the XYZ three-axis transfer mechanism, and the transfer speed is fast and the time is short, effectively improving the production efficiency of the sole-forming machine.

[0094] It should be noted that, in addition to the aforementioned, the wall-mounted bottom pressing machine and the bottom-form-free bottom pressing machine of this application... Figures 4-6 , Figures 10-12 In addition to what is shown, it can also be Figure 16 The rotary bottom press shown has two sides designed for feeding and discharging. Since the internal structure and working principle of the rotary bottom press are common knowledge, this article will not elaborate further.
