Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, specifically to a pentane foaming device for leather processing. Background Technology

[0002] In the leather processing industry, leather foaming is a crucial step that directly affects the texture, softness, and final product quality of the leather. In recent years, with the increasing awareness of environmental protection and the continuous advancement of processing technology, people have begun to explore more environmentally friendly and efficient leather foaming technologies. Among them, pentane, as an environmentally friendly physical foaming agent, has been gradually applied in the leather processing field due to its good foaming performance and recyclability.

[0003] Existing pentane foaming devices still have some shortcomings in leather processing. For example, during the pretreatment of leather before foaming, it is usually necessary to soak it in water to soften the leather and remove impurities. When the leather is soaked in water, due to the different seals between the leather and water, the leather will float on the surface of the water, making it difficult to ensure that the leather is evenly and fully soaked, thus affecting the subsequent foaming effect. Therefore, it is necessary to design a pentane foaming device for leather processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pentane foaming device for leather processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pentane foaming device for leather processing, comprising a tank, wherein sliding grooves are respectively provided on both sides of the interior of the tank, support rods are respectively installed inside the two sets of sliding grooves, lifting blocks are slidably connected to the outer sides of the two sets of support rods, springs are connected between the two sets of sliding grooves and the lifting blocks and the springs are located outside the sliding grooves, and a placement frame is connected between the two sets of lifting blocks;

[0006] The top of the tank is hinged to a cover plate, the bottom of the cover plate is fitted with a pushing assembly, the bottom of the pushing assembly is hinged to a moving plate, the bottom of the moving plate is fitted with a push plate, and the bottom of the placement frame is fitted with a filter screen, the moving plate, and the push plate respectively.

[0007] Preferably, the pushing assembly includes a support base, a bidirectional screw, a servo motor, and a hinge. Two sets of support bases are respectively installed at the bottom of the cover plate. The bidirectional screw is connected between the two sets of support bases by a bearing. The servo motor is installed on one side of one set of support bases and drives the bidirectional screw to rotate. The hinge is connected between the bidirectional screw and the moving plate.

[0011] Preferably, an expansion plate is installed at the bottom outer side of the tank, and multiple sets of support legs are installed in a ring around the bottom of the expansion plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By placing the leather into the placement frame and flipping the cover, the pushing component is activated, causing the moving plate to move downwards. The moving plate moves the push plate, which in turn presses against two sets of lifting blocks as it moves downwards. As the push plate moves, it pushes the lifting blocks, causing the lifting blocks to move the placement frame downwards. Filter screens are installed at the bottom of the placement frame, along with the moving plate and push plate, to ensure that the leather can fully contact the water and soak evenly during the soaking process. When the lifting blocks move downwards, the support rods installed inside the chute slide on the outside and compress the spring.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a pentane foaming device for leather processing, including a tank body 1. The tank body 1 has sliding grooves 2 on both sides inside. Support rods 3 are installed inside the two sets of sliding grooves 2 respectively. Lifting blocks 5 are slidably connected to the outside of the two sets of support rods 3 respectively. Springs 4 are connected between the two sets of sliding grooves 2 and the lifting blocks 5, and the springs 4 are located outside the sliding grooves 2. A placement frame 6 is connected between the two sets of lifting blocks 5.

[0022] A cover plate 7 is hinged to the top of the tank body 1. A pushing component is installed at the bottom of the cover plate 7. A moving plate 13 is hinged to the bottom of the pushing component. A push plate 14 is installed at the bottom of the moving plate 13. Filter screens 15 are installed at the bottom of the placement frame 6, the moving plate 13, and the push plate 14, respectively.

[0023] Specifically, by placing the leather into the placement frame 6, flipping the cover 7, and simultaneously activating the pushing component, the pushing component pushes the moving plate 13 downwards. The moving plate 13 drives the push plate 14 to move. As the push plate 14 moves downwards, it presses against two sets of lifting blocks 5. As the push plate 14 moves, it pushes the lifting blocks 5 downwards, causing the lifting blocks 5 to drive the placement frame 6 downwards. Filter screens 15 are installed at the bottom of the placement frame 6, along with the moving plate 13 and the push plate 14, to ensure that the leather can fully contact the water and soak evenly during the soaking process. When the lifting blocks 5 move downwards, they slide on the outside of the support rod 3 installed inside the slide groove 2 and compress the spring 4. Conversely, if the push plate 14 does not compress the lifting blocks 5, the reaction force of the spring 4 drives the placement frame 6 to return to its original position.

[0024] The driving component includes a support base 8, a bidirectional screw 9, a servo motor 11, and a hinge. Two sets of support bases 8 are respectively installed at the bottom of the cover plate 7. The bidirectional screw 9 is connected between the two sets of support bases 8 by a bearing. The servo motor 11 is installed on one side of one set of support bases 8 and drives the bidirectional screw 9 to rotate. The hinge is connected between the bidirectional screw 9 and the moving plate 13. By turning on the servo motor 11, the bidirectional screw 9 is driven to rotate between the two sets of support bases 8. The bidirectional screw 9 drives the hinge to move, so that the hinge pushes the moving plate 13 connected to the other end to move downward.

[0025] The hinge includes a hinge seat 10 and a hinge plate 12. Two sets of hinge seats 10 are threaded to the outer ends of the bidirectional screw 9, and two other sets of hinge seats 10 are installed on the top of the movable plate 13. Two sets of hinge plates 12 are hinged between the four sets of hinge seats 10. The hinge seats 10 move outside the bidirectional screw 9, pushing the hinge plates 12 to move. The other end of the hinge plates 12 pushes the movable plate 13 installed at the bottom of another set of hinge seats 10 to move downward.

[0026] Wherein: A stirring motor 16 is embedded in the bottom of the tank body 1, and a stirring blade 17 is installed at the output end of the stirring motor 16. By turning on the stirring motor 16, the stirring motor 16 drives the stirring blade 17 to rotate, thereby mixing the water and foaming agent in the tank body 1.

[0027] Wherein: a drain pipe 18 is installed at the bottom of the tank body 1, and a manual valve 19 is installed on the outside of the drain pipe 18. By rotating the manual valve 19, the liquid in the tank body 1 is discharged from the drain pipe 18.

[0028] Among them: an expansion plate 20 is installed at the bottom of the outer side of the tank body 1, and multiple sets of support legs 21 are installed in a ring at the bottom of the expansion plate 20. The tank body 1 is supported by the support legs 21 installed at the bottom of the expansion plate 20, while the distance between the drain pipe 18 and the ground is reserved.

[0029] Working Principle: This utility model provides a pentane foaming device for leather processing. The leather is placed in the placement frame 6, the cover plate 7 is flipped, and the servo motor 11 is turned on, driving the bidirectional screw 9 to rotate between two sets of support seats 8. The bidirectional screw 9 drives the hinge seat 10, which is threaded at both ends, to move. The hinge seat 10 pushes the hinge plate 12 to move. The other end of the hinge plate 12 pushes the moving plate 13, which is mounted on the bottom of another set of hinge seats 10, to move downwards. The moving plate 13 drives the push plate 14 to move. As the push plate 14 moves downwards, it simultaneously abuts against two sets of lifting blocks 5. With the push plate 14 moving downwards... The movement of 4 pushes the lifting block 5 downward, causing the lifting block 5 to move the placement frame 6 downward. Filter screens 15 are installed at the bottom of the placement frame 6, along with the moving plate 13 and the push plate 14, respectively, to ensure that the leather can fully contact the water and soak evenly during the soaking process. When the lifting block 5 moves downward, it slides on the outside of the support rod 3 installed inside the slide groove 2 and compresses the spring 4. Conversely, if the push plate 14 does not compress the lifting block 5, the reaction force of the spring 4 will drive the placement frame 6 to return to its original position.
