Description

Technical Field

[0001] The utility model relates to the field of leather processing, in particular to an execution device for leather stretching and clamping. Background Art

[0002] Drying fur is an essential step in fur processing. During the drying process, the fur needs to be secured to a stretcher. Existing stretchers consist of a gantry hanger, a stretcher frame located between the two arms of the gantry hanger, and a nail plate fixed to the frame to secure the fur. To use the stretcher, the frame is laid flat, and the fur is secured to the nail plate using multiple nails along its edges. The frame is then erected, stretched, and placed into the drying device. However, this stretching machine has many technical defects during use: ① It is necessary to manually fix the nails on the fur one by one, and after the fur is dried, the nails need to be removed manually one by one, which is inconvenient to operate, reduces production efficiency, and causes certain damage to the fur; ② The upper and lower stretching plate frames are separated by a cylinder during the stretching process to achieve the fur stretching effect. The tensile strength is high and it is easy to cause damage to the fur; ③ The fur processing process is a circular transmission method. Each production line can only proceed to the next drying operation after completing the fur fixation and stretching treatment. Even if multiple groups of fur are fixed, they can only wait until the previous stretching treatment is completed before continuing to the next operation, which seriously affects production efficiency and restricts the development of the enterprise.

[0003] Patent CN209162101U proposes a clamp for an automatic leather stretching machine. The clamp is installed on a guide rail and is driven to move on the guide rail by a linear drive mechanism. The clamp includes a clamp body, which has a through hole for the guide rail to pass through and move. One side of the clamp body has an opening for leather to enter, and a leather clamp is also provided at the opening on the clamp body.

[0004] In the above patent, the back and forth movement of the clamp on the guide rail is achieved through the cooperation of the drive cylinder. This cooperation method has certain defects: the translation stroke of the clamp on the guide rail will be limited by the stroke of the drive cylinder, and it cannot achieve translation and stopping at any position. In addition, if the clamp needs to be translated for a long length, the corresponding size of the drive cylinder needs to be made longer. When clamping leather, multiple clamps in different directions are often required to clamp and pull the leather at the same time. The corresponding drive cylinders also need to be distributed in different positions to achieve movement in different directions of different clamps, which will eventually lead to a relatively large occupied area of the entire stretcher. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an execution device for a leather clamp which can reduce the occupied area and realize the translation of the clamp to any position.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a leather clamp execution device, the leather clamp execution device is set on a horizontal guide rail, and drives the clamp to move horizontally along the guide rail. Its innovation lies in: the leather clamp execution device includes

[0007] An actuator seat, on the lower side of which is mounted a pair of movable rollers supported on and rolling along a guide rail, and the two movable rollers are driven by a linkage mechanism to roll synchronously in the same direction, and a limit assembly for limiting the position of the movable rollers is further provided at the bottom end of the actuator seat;

[0008] The front side of the actuator seat is also provided with a docking assembly for cooperating with the clamp. The docking assembly includes a vertically arranged docking cylinder, which is invertedly installed on the actuator seat. At the same time, a docking groove is opened on the upper end surface of the clamp to accommodate the piston rod of the docking cylinder.

[0009] Furthermore, the linkage mechanism is as follows: a driving sprocket is provided above the two moving rollers on the execution seat, and a driven sprocket is connected to one side of each of the two moving rollers, and the driven sprocket rotates synchronously with the moving rollers. The driving sprocket and the driven sprocket are rotated synchronously through a linkage chain. The driving sprocket is driven by a travel motor installed on the execution seat to rotate, and drives the driven sprocket to rotate, thereby driving the two moving rollers to roll on the guide rail.

[0010] Furthermore, the limiting assembly includes a pair of limiting plates arranged at the bottom end of the actuator seat, the two limiting plates are respectively located on both sides of the guide rail and extend along the long axis direction of the guide rail, and the length of the limiting plates is longer than the spacing between the two moving rollers.

[0011] Furthermore, a guide block is respectively provided on the inner side of the two limit plates, and the guide blocks extend along the long axis direction of the limit plates, and have an inclined guide slope on both sides of the long axis direction of the guide blocks, and the inclination direction of the guide slope is from the center position of the guide block to the end position of the guide block, gradually inclining toward the direction away from the guide rail.

[0012] The advantages of the present invention are that: the execution device in the present invention realizes the horizontal movement of the execution seat on the guide rail by cooperating with the execution seat and the moving roller, and limits the relative position between the execution seat and the guide rail by setting a limit component. This method is used to realize the movement of the clamp. Compared with the driving cylinder method, it is no longer restricted by the stroke and can realize the translation of the clamp to any position. Correspondingly, it can also reduce the floor space required by the execution device, and the entire leather tensioning device is more compact.

[0013] By setting a limit plate on both sides of the bottom of the actuator seat, a guide limit is provided for the horizontal movement of the actuator seat, ensuring that the actuator seat can move horizontally stably on the guide rail and preventing the actuator seat from deviating and falling from the guide rail.

[0014] The design of the guide blocks on the two limit plates is to serve as a guide and limit for the relative position between the actuator seat and the guide rail when the actuator seat switches and moves on two different guide rails, ensuring that the actuator seat can smoothly switch and move on the guide rails.

[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0019] like Figure 1-Figure 3 The illustrated embodiment shows an actuator for a leather clamp, which is arranged on a horizontally arranged guide rail 1. A clamp 2 for tightening the leather is arranged on the guide rail 1. The clamp 2 is driven by the actuator to move horizontally along the guide rail 1, thereby approaching or moving away from the leather to achieve clamping or tightening of the leather.

[0020] The actuator includes

[0021] An execution seat 3, a pair of movable rollers 301 supported on the guide rail 1 and rolling along the guide rail are installed on the lower side of the execution seat 3, the two sides of the movable rollers 301 are installed on the execution seat 3 through the cooperation of bearings and bearing seats, and rolling cooperation with the execution seat 3, the two movable rollers 301 are driven by a linkage mechanism to roll synchronously in the same direction, the linkage mechanism is: a driving sprocket 302 is also provided above the two movable rollers 301 on the execution seat 3, and a driving sprocket 302 is also connected to one side of the two movable rollers 301. A driven sprocket 303, and the driven sprocket 303 and the moving roller 301 rotate synchronously, and the driving sprocket 302 and the driven sprocket 303 rotate synchronously through the cooperation between the linkage chain 304. The driving sprocket 302 is driven by a walking motor 305 installed on the execution base 3 to rotate, and drives the driven sprocket 303 to rotate, and the rotation of the driven sprocket 303 will drive the two moving rollers 301 to rotate synchronously in the same direction, thereby realizing the horizontal movement of the execution base 3 on the guide rail 1.

[0022] A limiting assembly for limiting the position of the moving roller 301 is also provided at the bottom end of the actuator seat 3. The limiting assembly includes a pair of limiting plates 306 provided at the bottom end of the actuator seat 3. The two limiting plates 306 are respectively located on either side of the guide rail 1 and extend along the long axis of the guide rail 1. The length of the limiting plates 306 is longer than the spacing between the two moving rollers 301, and the height of the bottom end of the limiting plates 306 is lower than the height of the lower end surface of the guide rail 1. By providing a limiting plate 306 on each side of the bottom end of the actuator seat 3, a guiding and limiting function is provided for the horizontal movement of the actuator seat 3, ensuring that the actuator seat 3 can stably move horizontally on the guide rail 1, preventing the actuator seat 3 from deviating and falling from the guide rail. In addition, the provided limiting plates 306 can also provide a certain degree of protection for the moving roller 301, preventing external factors from interfering with the movement of the moving roller 301.

[0023] A guide block 307 is also provided on the inner side of each of the two limit plates 306. The guide block 307 is fixed to the limit plate 306 by bolts, and the height of the guide block 307 is lower than the height of the upper end surface of the guide rail 1 and higher than the height of the lower end surface of the guide rail 1. The guide block 307 extends along the long axis of the limit plate 306, and has an inclined guide slope on both sides of the long axis of the guide block 307. The inclination direction of the guide slope is from the center position of the guide block 307 to the end position of the guide block 307, gradually tilting away from the guide rail 1. The design of the guide blocks 307 on the two limit plates 306 is to play a guiding and limiting role in the relative position between the actuator seat 3 and the guide rail 1 when the actuator seat 3 switches and moves on two different guide rails 1, ensuring that the actuator seat 3 can smoothly switch and move on the guide rail 1.

[0024] A docking assembly for cooperating with the clamp 2 is also provided on the front side of the actuator seat 3. The docking assembly includes a vertically arranged docking cylinder 308, which is invertedly installed on the actuator seat 3. At the same time, a docking groove 201 is provided on the upper end surface of the clamp 2 to accommodate the piston rod of the docking cylinder 308.

[0025] Working principle: When the clamp 2 is moved, the travel motor 305 works to drive the active sprocket 302 to rotate, and then drives the two moving rollers 301 to work through the driven sprocket 303 and the linkage chain 304. The rotation of the moving roller 301 drives the actuator seat 3 to move toward the clamp 2. When the actuator seat 3 moves to the position of the clamp 2, the travel motor 305 stops working, and then the docking cylinder 308 works to insert the piston rod into the docking groove 201 on the clamp 2. Then the travel motor 305 continues to work, driving the actuator seat 3 to move on the guide rail 1, and driving the clamp 2 to translate on the guide rail 1.

[0026] Compared with the traditional driving cylinder method, the above-mentioned moving method is no longer limited by the driving cylinder stroke. It only needs a long enough line to power the walking motor 305. The lines themselves are flexible lines and do not take up too much hard space, so they do not need to occupy much floor space.

[0027] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
