Description

Technical Field

[0001] This utility model relates to the field of shoe sole processing technology, and more specifically to a shoe sole clamping device. Background Technology

[0002] Shoes are a necessity in people's daily lives, and their manufacturing industry has become a traditional industry closely related to human life. The shoe manufacturing process is complex. When spraying glue on the sole, clamping devices are mostly used to clamp the sole. However, because the sole has a certain degree of softness, the method of clamping hard will cause the side of the sole to bend inward, resulting in uneven glue spraying.

[0003] The existing shoe sole clamping device disclosed in CN214547701U uses a telescopic cylinder to push a clamping plate, which in turn pushes a spring and a limiting plate, bringing the limiting plate into contact with the shoe sole. A clamping rod and a clamping plate are also provided on the worktable. An electric telescopic rod pulls a connecting rod, which in turn pulls the clamping rod via a rotating cylinder. The clamping rod pushes the clamping plate to press the shoe sole, preventing it from bending due to clamping force. However, this invention has the following problems: during glue spraying, the contact point between the clamping plate and the shoe sole cannot be fully sprayed. Furthermore, after clamping and spraying the glue on the shoe sole, the machine needs to be paused, the old shoe sole removed, and a new shoe sole clamped, reducing processing efficiency and making it inconvenient to use. Therefore, this invention proposes a shoe sole clamping device. Utility Model Content

[0004] The purpose of this invention is to provide a shoe sole clamping device. After clamping, the adhesive is sprayed in place without stopping the machine, which improves work efficiency and is very convenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shoe sole clamping device includes two side plates. Several legs are fixedly mounted on the lower ends of the side plates. A first transport structure is provided between the side plates and their lower ends. A second transport structure is provided above the first transport structure between the side plates. The second transport structure includes a second transport belt. Several clamping parts are provided on the second transport belt. Each clamping part includes a base fixedly connected to the second transport belt on four sides and a main plate located on both sides. An inner groove is provided on the upper end of the base. Positioning posts are fixedly mounted on both sides of the lower end of the main plate at positions corresponding to the inner grooves. The positioning posts are inserted into the corresponding inner grooves for fixed connection. A secondary plate is fixedly mounted between the main plate and its two sides. A movable plate is provided on one side of the main plate via an adjustment part. A clamping plate is fixedly mounted on the side of the movable plate away from the adjustment part via several springs.

[0007] By adopting the above technical solution, this utility model has the following advantages:

[0008] The design of the first and second transport structures of this utility model allows the second transport structure to move the shoe sole for adhesive spraying, then move it to the unloading area to remove the shoe sole. The reverse movement of the second transport structure can move the clamping part to the loading area to continue clamping the shoe sole. This eliminates the need to stop the machine for clamping and removing the shoe sole, effectively improving work efficiency and making it very convenient to use. The design of the adjustment part, moving plate, spring, and clamping plate allows the moving plate to be adjusted and moved by the adjustment part, thereby clamping shoe soles of different sizes. The spring provides a certain elasticity between the clamping plate and the main plate, effectively preventing the clamping plate from clamping the shoe sole too tightly and causing deformation. Furthermore, clamping only the sides of the shoe sole ensures more thorough adhesive application.

[0009] Furthermore, the support leg is U-shaped.

[0010] By adopting the above technical solution, this utility model has the following advantages:

[0013] By adopting the above technical solution, this utility model has the following advantages:

[0014] The motor in this invention is designed to drive the main shaft to rotate, thereby moving the conveyor belt and the clamping part.

[0015] Furthermore, the second transport structure includes a second main shaft that is rotatably connected to the side plates on both sides. The second main shaft is fitted with the second transport belt. A second motor is fixedly mounted on one side plate. The output end of the second motor passes through the corresponding side plate and is fixedly connected to the corresponding second main shaft.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] The second motor in this invention drives the second main shaft to rotate, which in turn drives the second conveyor belt to move, thus moving the sole of the shoe.

[0018] Furthermore, the length of the first transport belt is greater than the length of the second transport belt.

[0019] By adopting the above technical solution, this utility model has the following advantages:

[0020] The present invention features a conveyor belt one that is longer than the conveyor belt two, which facilitates the handling of the clamping part by the staff.

[0021] Furthermore, the positioning post is fixedly provided with several protrusions, the base is made of elastic material, and the inner groove of the base is fixedly provided with several grooves corresponding to the positions of the protrusions, and the protrusions are engaged in the corresponding grooves.

[0022] By adopting the above technical solution, this utility model has the following advantages:

[0023] The protrusions and grooves in this invention enhance the connection between the positioning post and the base, making it possible to remove the positioning post only under a certain pulling force.

[0024] Furthermore, the adjustment part includes a threaded post, which passes through the corresponding main board and is threadedly connected to the main board. One end of the threaded post is rotatably connected to the corresponding movable plate, and the other end of the threaded post is fixedly connected to the handle.

[0026] The threaded post in this invention allows the rotation of the threaded post to move the movable plate, thereby clamping and fixing the shoe sole to the main plate.

[0027] Furthermore, the threaded post is provided with dimensional lines.

[0028] By adopting the above technical solution, this utility model has the following advantages:

[0029] The design of the dimension line in this invention allows for comparison and adjustment of only a single clamping part against the shoe sole before processing. Subsequent clamping parts only need to be adjusted according to the position of the adjusted threaded column dimension line, making clamping part adjustment more convenient.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown in this specific embodiment, a shoe sole clamping device includes two side plates 1. Several support legs 101 are fixedly provided at the lower end of the side plates 1. A first transport structure is provided between the side plates 1 and the lower end of the side plates 1. A second transport structure is provided at the upper end of the first transport structure between the side plates 1 and the side plates 1. The second transport structure includes a second transport belt 201. Several clamping parts are provided on the second transport belt 201. The clamping parts include a base 7 fixedly connected to the second transport belt 201 on all four sides and a main plate 13 located on both sides. An embedded groove 701 is provided at the upper end of the base 7. Positioning posts 8 are fixedly provided on both sides of the lower end of the main plate 13 at the positions corresponding to the embedded groove 701. The positioning posts 8 are inserted into the corresponding embedded groove 701 for fixed connection. A secondary plate 4 is fixedly provided between the main plate 13 and the two sides of the main plate 13. A movable plate 5 is provided on one side of the main plate 13 through an adjustment part. A clamping plate 12 is fixedly provided on the side of the movable plate 5 away from the adjustment part through several springs 11.

[0039] Through the above configuration, the first and second transport structures of this utility model enable the second transport structure to move the sole to apply adhesive, then move to the unloading point to remove the sole. The reverse movement of the second transport structure can move the clamping part to the loading point to continue clamping the sole. This eliminates the need to stop the machine for clamping and removing the sole, effectively improving work efficiency and making it very convenient to use. The adjustment part, moving plate 5, spring 11, and clamping plate 12 of this utility model allow the moving plate 5 to be adjusted and moved by the adjustment part, thereby clamping soles of different sizes. The spring 11 provides a certain elasticity between the clamping plate 12 and the main plate 13, effectively preventing the clamping plate 12 from clamping the sole too tightly and causing deformation. Furthermore, clamping only the sides of the sole ensures more thorough adhesive application.

[0040] like Figure 1 and Figure 3 As shown, the support leg 101 is U-shaped; the first transport structure includes a main shaft 3 rotatably connected to the side plates 1 on both sides, a transport belt 301 is sleeved on the main shaft 3, a motor 10 is fixedly installed on one side plate 1, and the output end of the motor 10 passes through the corresponding side plate 1 and is fixedly connected to the corresponding main shaft 3; the second transport structure includes a second main shaft 2 rotatably connected to the side plates 1 on both sides, a transport belt 201 is sleeved on the main shaft 2, a motor 9 is fixedly installed on one side plate 1, and the output end of the motor 9 passes through the corresponding side plate 1 and is fixedly connected to the corresponding main shaft 2; the length of the first transport belt 301 is greater than the length of the second transport belt 201.

[0041] With the above configuration, the U-shaped support leg 101 of this utility model makes the overall structure more stable; the motor 10 of this utility model drives the main shaft 3 to rotate, thereby moving the conveyor belt 301 and the clamping part; the motor 9 of this utility model drives the main shaft 2 to rotate, thereby moving the conveyor belt 201 and the sole of the shoe; the length of the conveyor belt 301 is greater than that of the conveyor belt 201, making it easier for workers to handle the clamping part.

[0042] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the positioning post 8 is fixedly provided with several protrusions 801, the base 7 is made of elastic material, and the inner groove 701 of the base 7 is fixedly provided with several grooves 702 corresponding to the positions of the protrusions 801, and the protrusions 801 are engaged in the corresponding grooves 702; the adjustment part includes a threaded post 6, which passes through the corresponding main plate 13 and is threadedly connected to the main plate 13, one end of the threaded post 6 is rotatably connected to the corresponding moving plate 5, and the other end of the threaded post 6 is fixedly connected to the handle 601. The moving plate 5 is fixedly provided with sliders 501 on both sides corresponding to the positions of the sub-plate 4, and the sub-plate 4 is provided with a sliding groove 401 corresponding to the position of the slider 501, and the slider 501 is engaged in the corresponding sliding groove 401 and can be movably connected; the threaded post 6 is provided with a dimension line 602.

[0043] Through the above settings, the protrusion 801 and groove 702 of this utility model enhance the connection strength between the positioning post 8 and the base 7, so that the positioning post 8 can only be removed under a certain pulling force; the threaded post 6 of this utility model allows the rotation of the threaded post 6 to drive the moving plate 5 to move and clamp and fix the shoe sole with the main board 13; the dimension line 602 of this utility model allows only a single clamping part to be picked up and compared with the shoe sole before processing, and subsequent clamping parts only need to be adjusted according to the position of the dimension line 602 of the threaded post 6 after adjustment, making the adjustment of the clamping parts more convenient.

[0044] Working principle: When in use, place this invention at the lower end of the glue spraying equipment, aligning the center of conveyor belt 201 with the glue outlet. A certain number of clamping parts are placed according to the size of the shoe soles in this batch. The shoe soles are placed between the main plates 13, with one side of the sole abutting against one side of the main plate 13. Turning the handle 601 rotates the threaded column 6, thereby moving the moving plate 5 towards the side of the shoe sole until the clamping plate 12 clamps the shoe sole against the other side of the main plate 13. The spring 11 provides a certain elasticity between the clamping plate 12 and the main plate 13. To prevent deformation of the shoe sole, each clamping part is adjusted to the correct position according to dimension line 602. Two workers stand on either side of the machine and start it. One worker inserts the positioning pin 8 of the clamping part into the corresponding base 7 for fixation, then presses the clamping plate 12 against the spring 11, placing the shoe sole between the main board 13 and the clamping plate 12. The clamping plate 12 is released, and it will move back to clamp and fix the shoe sole due to the elastic force of the spring 11. At this time, the motor 29 starts and drives the conveyor belt 201 to move. When the clamping part with the shoe sole moves to the glue spray nozzle... At the lower end, motor 29 stops starting, conveyor belt 201 stops moving, and the glue nozzle applies glue to the sole. While applying glue, the worker can continue to fix the new clamping part on conveyor belt 201 to clamp the sole in place. At this time, motor 29 starts and moves the new sole to the glue application area. The time interval between starting and stopping motor 29 can be set according to the glue application time. When the glued sole moves to the other side of this utility model, the worker on the other side removes the clamping part, removes the sole, and then places the clamping part on conveyor belt 301. 10 is always activated, driving conveyor belt 301 to move in the opposite direction to conveyor belt 201, thereby moving the clamping part without the sole to the other side for the staff on the other side to take and clamp the sole of the military personnel. This is repeated. After clamping, the glue is sprayed in place without stopping the machine, which improves work efficiency and is very convenient to use. The circuit connection lines and methods of motor 10, motor 29 and motor 10 and motor 29 are all disclosed in the prior art, so this application will not elaborate further.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
