However, traditional heel counter machines still have the following problems in use:

[0003] Traditional heel counters are prone to misalignment when clamping and fixing shoes during processing, which makes it difficult to fully compress the heel area. In addition, some machines are prone to uneven pressure distribution during extrusion processing. This not only affects the processing quality of the shoes, but may also cause deformation or discomfort during later wear. Utility Model Content

[0004] The purpose of this invention is to provide an automatic centering pressure uniform distribution device for a heel counter. In this invention, the device achieves precise centering of the shoe's height and horizontal position through the coordinated adjustment of the first and second cylinders. The clamping assembly utilizes springs, traction rings, and anti-slip textures to ensure stable centering of the shoe, improving centering accuracy. The extrusion assembly employs a dual-axis cylinder and an air pump to ensure synchronous movement of the two extrusion plates, achieving uniform pressing of the mid- and heel counter parts of the shoe, improving processing quality, preventing shoe deformation, and solving existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

A rotating plate is rotatably sleeved on the outer wall of each of the two fixed rods. A clamping plate is fixedly installed on one side of each of the two rotating plates. The two clamping plates cooperate to clamp and fix the shoe to be processed. Two fixed plates are fixedly installed on the top of the second slider. Both fixed plates are located between the two fixed rods. A first guide rod and a second guide rod slide through the interior of each of the two fixed plates. The second guide rod is located below the first guide rod. One end of the first guide rod and the second guide rod are fixedly connected by a connecting plate.

Four traction rings are fixedly installed on the outer wall of the collar, the four traction rings being arranged in pairs and located on both sides of the collar. Fixed posts are fixedly inserted through the interior of each of the two rotating plates, and the two fixed posts are located at positions off-center from the rotation center of the corresponding rotating plates. The two traction rings on the same side cooperate with the adjacent fixed posts to achieve the opening and closing clamping of the two clamping plates.

[0013] Optionally, a mounting post is fixedly installed on the top of the first slider, a connecting frame is fixedly installed on one side of the first slider, and an arc-shaped plate is fixedly installed on the other end of the connecting frame. The mounting post and the arc-shaped plate are used to place the shoe to be processed.

[0014] Optionally, an abutment plate is fixedly installed on one side of the first slider, and the abutment plate abuts against one end of the second guide rod to control the two clamping plates to open and close.

[0015] Optionally, the extrusion assembly includes a top plate fixedly mounted on the top of two fixed rods. Two extrusion plates are slidably connected to the bottom of the top plate. The two extrusion plates cooperate with each other and are slidably engaged with adjacent clamping plates. Two dual-axis cylinders are fixedly mounted on the bottom of the top plate. The two dual-axis cylinders are located on opposite sides of the two extrusion plates. One end of the piston rod of each dual-axis cylinder is fixedly connected to one side of the adjacent extrusion plate, driving the two extrusion plates to move, thereby completing the extrusion processing of the shoe to be processed.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0035] Example 1: Please refer to Figure 1-7 As shown, this embodiment provides an automatic centering pressure uniform distribution device for a back-end machine, comprising:

[0036] The outer casing 1 has a support frame 2 fixedly installed inside it, with one side of the support frame 2 extending to one side of the outer casing 1.

[0037] It also includes a first slider 3, which is vertically slidably disposed within the support frame 2. The first slider 3 is used to place the shoe to be processed. A first cylinder 5 is fixedly embedded inside the support frame 2. One end of the piston rod of the first cylinder 5 is fixedly connected to the bottom of the first slider 3, and is used to adjust the height of the shoe to be processed.

[0038] Furthermore, to center and clamp the shoe to be processed, this embodiment also includes a clamping assembly. The clamping assembly includes two fixed rods 11 fixedly mounted on the top of the second slider 4. A rotating plate 19 is rotatably sleeved on the outer wall of each of the two fixed rods 11. A clamping plate 20 is fixedly mounted on one side of each of the two rotating plates 19. The two clamping plates 20 cooperate with each other to clamp and fix the shoe to be processed. The second slider 4 is horizontally slidably disposed within the support frame 2. A second cylinder 6 is fixedly mounted on the inner wall of one side of the outer shell 1. One end of the piston rod of the second cylinder 6 is fixedly connected to one side of the second slider 4. By extending and retracting the piston rod of the second cylinder 6, the second slider 4 can be driven to slide horizontally within the support frame 2, thereby moving the clamping assembly to achieve centering clamping of the shoe.

[0039] To control the opening and closing of the two clamping plates 20, in this embodiment, two fixing plates 13 are fixedly installed on the top of the second slider 4, and both fixing plates 13 are located between the two fixing rods 11. A first guide rod 14 and a second guide rod 15 slide through the interior of each of the two fixing plates 13, with the second guide rod 15 located below the first guide rod 14. One end of the first guide rod 14 and the second guide rod 15 are fixedly connected by a connecting plate. A collar 17 is fixedly sleeved on the outer wall of the first guide rod 14, located between the two fixing plates 13. A spring 16 is sleeved on the outer wall of the first guide rod 14, with one end of the spring 16 fixedly connected to one side of the collar 17 and the other end of the spring 16 fixedly connected to one side of the adjacent fixing plate 13. Under the elastic force of the spring 16, the collar 17 can be pushed to one side, thereby causing the first guide rod 14 and the second guide rod 15 to move synchronously.

[0040] In this embodiment, four traction rings 18 are fixedly installed on the outer wall of the collar 17. The four traction rings 18 are arranged in pairs and located on both sides of the collar 17. A fixing post 21 is fixedly inserted through the interior of each of the two rotating plates 19. The two fixing posts 21 are located at positions off-center from the rotation center of the corresponding rotating plate 19. The two traction rings 18 on the same side cooperate with the adjacent fixing post 21. When the collar 17 moves, the cooperation between the traction rings 18 and the fixing post 21 drives the rotating plate 19 to rotate, thereby achieving the opening and closing clamping of the two clamping plates 20.

[0041] In this embodiment, an abutment plate 7 is fixedly installed on one side of the first slider 3, and the abutment plate 7 abuts against one end of the second guide rod 15. When the second slider 4 drives the clamping assembly to move, the abutment plate 7 will first contact the second guide rod 15 and push the second guide rod 15 to one side, thereby driving the first guide rod 14 and the collar 17 to move through the connecting plate, realizing the opening and closing of the two clamping plates 20.

[0042] In addition, this embodiment also includes an extrusion assembly for pressing the mid-sole and heel counter of the shoe to be processed. The extrusion assembly includes a single top plate 12 fixedly mounted on the top of two fixed rods 11. Two extrusion plates 24 are slidably connected to the bottom of the top plate 12. The two extrusion plates 24 cooperate with each other, and both extrusion plates 24 are slidably engaged with adjacent clamping plates 20. Two dual-axis cylinders 23 are fixedly mounted on the bottom of the top plate 12, and the two dual-axis cylinders 23 are respectively located on the side of the two extrusion plates 24 that are far apart from each other. One end of the piston rod of each of the two dual-axis cylinders 23 is fixedly connected to one side of the adjacent extrusion plate 24. By extending and retracting the piston rod of the dual-axis cylinder 23, the two extrusion plates 24 can be driven to move, thereby completing the extrusion processing of the shoe to be processed. An air supply pump 25 is fixedly mounted on the top of the top plate 12. The air supply pump 25 delivers air to the two dual-axis cylinders 23 simultaneously through pipes to ensure that the extrusion plates 24 on both sides can move synchronously, thereby achieving uniform pressing.

[0043] This application can be used in the field of shoemaking equipment technology, or in other fields applicable to this application.

[0044] Example 2: Reference Figure 4 , 6 An improvement based on Example 1: an automatic centering pressure uniform distribution device for a back-end machine, which is applied to the field of shoemaking equipment technology.

[0045] In order to place the shoes to be processed more stably, in this embodiment, a mounting post 8 is fixedly installed on the top of the first slider 3, a connecting frame 9 is fixedly installed on one side of the first slider 3, and an arc plate 10 is fixedly installed on the other end of the connecting frame 9. The mounting post 8 and the arc plate 10 cooperate with each other to complete the placement of the shoes to be processed.

[0046] In order to ensure sufficient limiting of the two clamping plates 20, in this embodiment, a relief groove 22 is provided on the side of the two clamping plates 20 that are close to each other. The two relief grooves 22 are slidably engaged with the first guide rod 14. When the two clamping plates 20 are close to each other, the first guide rod 14 can pass smoothly through the relief groove 22 to ensure sufficient limiting of the two clamping plates 20.

[0047] Meanwhile, in this embodiment, the two clamping plates 20 are also provided with anti-slip textures on the side that is close to each other to increase the friction between them and the shoes and ensure stable clamping of the shoes to be processed.

[0048] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 5, the second cylinder 6, the dual-shaft cylinder 23 and the air supply pump 25 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0049] The usage process and working principle of this utility model technical solution are as follows:

[0050] In use, the user can place the shoe opening of the shoe to be processed onto the mounting post 8, and place the upper part of the shoe onto the curved plate 10 to complete the shoe placement. Then, the first cylinder 5 can push the first slider 3 to rise, thereby adjusting the position of the sole of the first slider 3. At the same time, the second cylinder 6 can push the second slider 4 closer to the first slider 3. As the second slider 4 gradually approaches, the second guide rod 15 will abut against one side of the abutment plate 7. At this time, the first guide rod 14 and the second guide rod 15 will move backward relative to the second slider 4, and the collar 17 will also move backward synchronously with the first guide rod 14. Then, through the traction ring 18 and the fixing post 21, the two clamping plates 20 are pulled together. The positioning and clamping of the shoe to be processed is completed. After the fixation is completed, the air supply pump 25 can supply air to the two dual-axis cylinders 23 at the same time. At this time, the two dual-axis cylinders 23 can push the extrusion plate 24 at the same time. The two extrusion plates 24 can extrude and process the middle and back positions of the shoe to be processed. After the processing is completed, according to the above operation, multiple corresponding piston rods retract in sequence. When the second cylinder 6 retracts the piston rod, the first guide rod 14 and the second guide rod 15 can be pushed out again under the pushing action of the spring 16, thereby completing the separation of the two clamping plates 20. At this time, the user can take out the processed shoe and wait for the next processing.

[0051] It should be noted that in the description of this specification, descriptions such as "first" and "second" are only used to distinguish the features and do not have any actual order or directional meaning. This application is not limited to this.
