Description

Technical Field

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

[0002] Vacuum drying of cowhide is a highly efficient drying method widely used in cowhide production. The working principle of vacuum drying is to use steam as a heat source under vacuum conditions, supplying sufficient heat to the moisture in the leather through conduction, allowing evaporation and boiling to occur simultaneously, accelerating the vaporization rate. At the same time, the vacuum process rapidly removes the vaporized steam, creating a negative pressure around the leather. This forms a significant humidity gradient between the inner and outer layers of the leather and between the surface and the surrounding medium, further accelerating vaporization and achieving rapid drying. Currently, leather processing requires placing the leather on racks, which are then placed inside the dryer. Before and after processing, the racks need to be lifted in and out by personnel, which is inconvenient and increases the burden on workers. Therefore, we have introduced a vacuum drying equipment for cowhide. Utility Model Content

[0003] The main objective of this invention is to provide a vacuum drying equipment for cow leather, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A vacuum drying equipment for cow leather includes a vacuum dryer and a support device. Support legs are fixedly connected to the four corners of the lower end of the vacuum dryer. A door panel is movably connected to the left front end of the vacuum dryer via a hinge. A handle is fixedly connected to the door panel. A lifting device is placed inside the vacuum dryer.

[0006] Preferably, the support device includes a base, a shim block is fixedly connected to the front end of the base, and connectors are fixedly connected to the front left and front right ends of the base. The upper ends of the two connectors are both arc-shaped structures. The ends of the two connectors that are close to each other are movably connected to a movable support plate through a rotating shaft. A motor is fixedly connected to the rear upper end of the base.

[0007] By adopting the above technical solution, the shim can fill the gap at the end of the movable pallet, preventing it from bumping or shaking.

[0008] Preferably, a rotating rod is fixedly connected to the output end of the motor, a support seat is movably connected to the left end of the rotating rod via a bearing, a connecting rod is fixedly connected to the outer surface of the rotating rod, and a top rod is fixedly connected to one end of the connecting rod.

The connecting rod and the top rod on the outer surface of the rotating rod follow the rotation of the rotating rod to adjust their angles. When the top rod is adjusted, it will lift the movable pallet. The movable pallet is lifted and forms a ramp, so that the lifting device can be loaded and unloaded at the front of the vacuum dryer through the movable pallet, which improves the convenience of loading and unloading and avoids increasing the burden on the staff during handling.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A vacuum drying equipment for cow leather includes a vacuum dryer 1 and a support device 3. Support legs 2 are fixedly connected to the four corners of the lower end of the vacuum dryer 1. A door panel 6 is movably connected to the left front end of the vacuum dryer 1 via a hinge. A handle 4 is fixedly connected to the door panel 6. A lifting device 5 is placed inside the vacuum dryer 1.

[0025] In this embodiment, the support device 3 includes a base 31, with a raised block 33 fixedly connected to the front end of the base 31. Connectors 32 are fixedly connected to the front left and front right ends of the base 31. The upper ends of the two connectors 32 are both arc-shaped structures. The ends of the two connectors 32 that are close to each other are movably connected to a movable support plate 34 through a rotating shaft. A motor 35 is fixedly connected to the rear upper end of the base 31. A rotating rod 352 is fixedly connected to the output end of the motor 35. A support seat 351 is movably connected to the left end of the rotating rod 352 through a bearing. A connecting rod 353 is fixedly connected to the outer surface of the rotating rod 352. A top rod 354 is fixedly connected to one end of the connecting rod 353. The length of the top rod 354 is greater than the length of the rotating rod 352, and the diameter of the top rod 354 is greater than the diameter of the rotating rod 352. The motor 35 and the support seat 351 are both fixedly connected to the base 31, and the top rod 354 contacts the lower end of the movable support plate 34.

[0026] Through the above scheme: the motor 35 is started, and the power output of the motor 35 is directly applied to the rotating rod 352. As the motor 35 runs smoothly, the rotating rod 352 begins to rotate at a constant speed. The connecting rod 353 and the top rod 354 on its outer surface are adjusted at their angles accordingly. During the adjustment process, the top rod 354 will precisely lift the movable support plate 34. The movable support plate 34 is made of lightweight and high-strength material, which not only ensures the load-bearing capacity but also facilitates a quick response to the action of the top rod 354. When the movable support plate 34 is lifted and forms a ramp, the lifting device 5 can easily move up and down along this ramp at the front end of the vacuum dryer 1.

[0027] In this embodiment, the lifting device 5 includes a first placement plate 51, with rollers 52 fixedly connected to the four corners of the lower end of the first placement plate 51, and support rods 53 fixedly connected to the four corners of the upper end of the first placement plate 51. The upper ends of the four support rods 53 are jointly fixedly connected to a second placement plate 54, and the four support rods 53 are jointly inserted and fixedly connected to a third placement plate 55. The second placement plate 54 is located above the third placement plate 55, and the first placement plate 51 is located below the third placement plate 55. All four rollers 52 are in contact with the lower inner wall of the vacuum dryer 1.

[0028] It should be noted that this utility model describes a vacuum drying equipment for cow leather. By setting up a support device 3, the leather to be processed is first placed stably on a specially designed lifting device 5. Then, the operator slowly moves the lifting device 5 to the front end of the vacuum dryer 1, preparing for the next operation. At this time, the motor 35 is started, and the power output of the motor 35 is directly applied to the rotating rod 352. As the motor 35 runs smoothly, the rotating rod 352 begins to rotate at a uniform speed. The connecting rod 353 and the top rod 354 on its outer surface are adjusted at the same angle. During the adjustment process, the top rod 354 will accurately lift the movable pallet 34. The movable pallet 34 is made of lightweight and high-strength material, which not only ensures the load-bearing capacity, but also facilitates a quick response to the action of the top rod 354. When the movable pallet 34 is lifted and forms a ramp, the lifting device 5 can easily move up and down along this ramp at the front of the vacuum dryer 1. This innovative design greatly simplifies the process of leather entering the vacuum dryer 1, not only improving the convenience of operation, but also significantly reducing the need for manual handling, thereby effectively avoiding the extra burden on the staff caused by handling work.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
