Description

Technical Field

[0001] This utility model relates to the field of leather drying technology, and in particular to a leather vacuum drying and fixing device. Background Technology

[0002] In the leather processing industry, drying is a crucial step in ensuring leather quality and improving the efficiency of subsequent processing. The effectiveness of fixing the leather before drying directly affects the smoothness, shape integrity, and final quality of the dried leather. Currently, traditional fixing methods in the leather drying process generally have many technical drawbacks, making it difficult to meet the diverse and high-quality leather processing needs.

[0003] Traditional leather fastening devices are mostly designed in a single specification. The position and size of their fastening structure are usually fixed and can only be adapted to leather of a specific width and length. Some devices require adjusting the fixing points one by one using bolts, buckles and other components. Operators need to repeatedly disassemble and tighten them with the help of tools. This not only involves many steps and is time-consuming, but also requires a high level of technical proficiency from the operator. Other devices use manual pressing to fix the leather. Operators need to apply pressure continuously until the drying is complete. Prolonged operation can easily lead to hand fatigue and increase the intensity of manual labor. Utility Model Content

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-4 This utility model provides an embodiment of a leather vacuum drying and fixing device, comprising a base plate 1, a first protective cover 2 fixedly connected to the upper side of the base plate 1, a first fixing frame 3 disposed inside the upper end of the first protective cover 2, a heat-conducting plate 4 fixedly connected to the lower side of the first fixing frame 3, adjustment grooves 5 formed on the inner sides of the front and rear ends of the first fixing frame 3, and adjustment plates 6 disposed on the inner sides of the left and right ends of the first fixing frame 3. Adjustment blocks 7 are fixedly connected to the front and rear ends of the adjustment plates 6, the outer walls of the adjustment blocks 7 are slidably connected to the inside of the adjustment grooves 5, and sliding blocks 7 are slidably connected to the inner sides of the front and rear ends of the adjustment plates 6. A movable rod 9 is inserted through the middle of block 8 and slider 8. A pressure plate 10 is fixedly connected to the lower end of the movable rod 9. A limit plate 12 is fixedly connected to the top of the movable rod 9. A spring 11 is provided on the outside of the lower end of the movable rod 9. A movable plate 13 is provided on the upper side of the adjusting plate 6. Side plates 14 are fixedly connected to the left and right sides of the middle of the movable plate 13. Bolts 15 are fixedly connected to the lower sides of the front and rear ends of the movable plate 13. The lower end of the bolt 15 is inserted inside the adjusting plate 6. The upper outer wall of the movable rod 9 is movably connected to the inner side of the movable plate 13. The lower side of the limit plate 12 is close to the upper side of the movable plate 13.

[0019] First, the operator lays the wet leather to be dried flat on the heat-conducting plate 4. Then, by grasping the side plate 14, the operator pulls the movable plate 13 upward. Since the upper outer wall of the movable rod 9 is movably connected to the inner side of the movable plate 13, and the lower side of the limiting plate 12 is tightly attached to the upper side of the movable plate 13, when the movable plate 13 rises, it will drive the movable rod 9 upward through the limiting plate 12. This will cause the pressure plate 10, which is fixedly connected to the lower end of the movable rod 9, to rise as well. The spring 11, which is sleeved on the lower end of the movable rod 9, will be compressed. The elastic characteristics of the spring 11 provide power for the subsequent automatic reset and pressure fixation of the pressure plate 10. Applying a force in the left and right direction, the adjusting plate 6 slides in the adjusting groove 5 on the inner side of the front and rear ends of the first fixing frame 3 through the adjusting blocks 7 fixedly connected at both ends, thereby realizing the left and right position adjustment of the adjusting plate 6. When the adjusting plate 6 moves to a suitable position that matches the width of the leather, the operator releases the side plate 14. At this time, the compressed spring 11 releases its elastic potential energy, pushing the pressure plate 10 to descend quickly and press tightly against the leather surface.

[0020] Reference Figures 1-4 The lower end of the first protective cover 2 is fixedly connected to the second fixed frame 16. The upper and lower sides of the second fixed frame 16 are fixedly connected to the partition 19. The partition 19 on the upper side of the second fixed frame 16 has a through hole 20 in the middle. The left side of the first protective cover 2 is fixedly connected to the control box 18. The second fixed frame 16 is equipped with a heating tube 17. The left end of the heating tube 17 passes through the second fixed frame 16 and the left end of the first protective cover 2 and is fixedly connected to the inside of the control box 18. The upper side of the base plate 1 is fixedly connected to the U-shaped plate 21. The left end of the U-shaped plate 21 is fixedly connected to the upper side of the control box 18. The middle part of the U-shaped plate 21 is fixedly connected to the electric push rod 22. The driving end of the electric push rod 22 is fixedly connected to the second protective cover 23. The left and right sides of the second protective cover 23 are fixedly connected to the fixing ears 24. The inner wall of the fixing ears 24 is slidably connected to the outer side of the U-shaped plate 21. The left end of the second protective cover 23 is fixedly connected to the suction pipe 25 for connecting the vacuum pump.

[0021] After the leather is secured, the electric push rod 22 of the device is activated. The drive end of the electric push rod 22 will drive the second protective cover 23 to descend vertically. The fixing ears 24 fixedly connected to the left and right sides of the second protective cover 23 slide along the outside of the U-shaped plate 21. After the second protective cover 23 is completely sealed with the first protective cover 2, the suction pipe 25 fixedly connected to the left end of the second protective cover 23 is connected to the external vacuum pump. The vacuum pump is started, and the gas inside the sealed space of the device is continuously extracted through the suction pipe 25 to form a stable vacuum environment inside the device. Under vacuum, the boiling point of the water inside the leather is greatly reduced, and the water is more likely to evaporate from the liquid state to the gas state. At the same time, it can effectively avoid the problem of the leather surface water evaporating too quickly and forming a hardened layer due to the presence of air in the traditional heating and drying process, which hinders the evaporation of internal water. This significantly improves the uniformity and efficiency of leather drying, reduces drying time, and reduces energy consumption. The control box 18 will adjust the temperature parameters according to the preset parameters. The heating tube 17 inside the second fixed frame 16 is precisely controlled for heating. The heat generated by the heating tube 17 after being powered on is first transferred to the partitions 19 fixedly connected to the upper and lower sides of the second fixed frame 16. The partitions 19 not only fix and protect the heating tube 17, but also transfer the heat to the heat-conducting plate 4 through the through holes of the upper partition 19, so that the temperature of the heat-conducting plate 4 rises evenly. The leather is laid flat on the heat-conducting plate 4, and the heat-conducting plate 4 will transfer the heat to the leather stably and evenly, heating the leather from all directions. Under the dual effect of vacuum environment and uniform heating, the moisture inside the leather evaporates quickly and evenly. The water vapor generated by evaporation is promptly extracted from the outside of the device by the vacuum pump through the suction pipe 25, thereby achieving efficient and high-quality drying of the leather.

[0022] Working principle: When drying leather, the wet leather is laid flat on the heat-conducting plate 4. Then, the movable plate 13 is pulled upward by the side plate 14. The movable plate 13 drives the movable rod 9 and the pressure plate 10 to move upward through the limiting plate 12, and compresses the spring 11. Then, a force is applied to the left and right, so that the adjusting plate 6 moves left and right through the adjusting block 7 to adjust it to a suitable position. Then, the side plate 14 is released, and the compressed spring 11 pushes the pressure plate 10 down and presses it on the leather to fix the leather after it is laid flat. Then, the electric push rod 22 is activated to drive the second protective cover 23 down, so that it covers the upper side of the first protective cover 2. The exhaust pipe 25 is connected to a vacuum pump to extract the gas inside the device during the heating process. The control box 18 can control the heating tube 17 inside the first fixing frame 3 to heat the surrounding air and transfer it to the heat-conducting plate 4 to dry the leather.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
