Description

Technical Field

[0001] The utility model belongs to the technical field of cowhide preparation, and particularly relates to a vibration-assisted rotary drum for removing salt from cowhide. Background Art

[0002] In the leather processing industry, salt removal from cowhide is an important step in the leather making process. Its purpose is to remove the salt attached to the cowhide to facilitate subsequent processing. Currently, common salt removal equipment includes a drum. Through the rotation of the drum and the coordination of the internal structure, the cowhide rolls and collides in the drum, thereby removing the salt on the surface.

[0003] However, existing salt-removing drum technology has some significant problems. First, due to the unreasonable structural design of the drum's inner drum, cowhide easily piles up on the side wall of the drum's inner drum during the salt-removing process. This not only affects the salt-removing effect, but may also cause the drum's inner drum to wear faster due to excessive force on one side, reducing the drum's service life. Second, the traditional drum design has shortcomings in vibration-assisted salt removal, which cannot effectively remove the salt from the cowhide, affecting the quality of the leather.

[0004] In view of the above problems, the present application proposes an improved design of a vibration-assisted drum for salt removal from cowhide. Utility Model Content

[0005] The utility model aims to provide a vibration-assisted drum for removing salt from cowhide, which can improve the salt-removing effect, reduce the uneven force on the inner cylinder of the drum, and extend its service life.

[0006] The technical solutions adopted by this utility model are as follows:

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0021] like Figure 1-3 As shown, a vibration-assisted drum for throwing salt off cowhide comprises an outer cylinder 1, the interior of the outer cylinder 1 being rotatably connected to an inner cylinder 2, through holes 3 being evenly provided on the bottom and circumferential side surfaces of the inner cylinder 2. When the inner cylinder 2 rotates, the salt particles on the cowhide inside will fly out due to the shaking of the cowhide and fly out of the interior of the inner cylinder 2 through the through holes 3. A rotating block 15 is rotatably connected to the inner side of the outer cylinder 1 and located on one side of the inner cylinder 2. A motor 6 is installed on the outside of the outer cylinder 1, and the output end of the motor 6 passes through the outer cylinder 1 and is connected to the rotating block 15.

[0022] A synchronous rotation mechanism is installed between the rotating block 15 and the inner cylinder 2. The synchronous rotation mechanism is used to drive the rotating block 15 and the inner cylinder 2 to rotate synchronously. The synchronous rotation mechanism includes a driven transmission shaft 4 slidably connected to the outside of the inner cylinder 2. A driving transmission shaft 16 is fixed to the outside of the rotating block 15, and the driving transmission shaft 16 and the driven transmission shaft 4 are transmitted through a transmission belt 5. The driven transmission shaft 4 is rotationally connected to the outer cylinder 1. Through the setting of the transmission belt 5, the transmission belt 5 can drive the driving transmission shaft 16 and the driven transmission shaft 4 to rotate, and drive the inner cylinder 2 to rotate. The sliding connection between the driven transmission shaft 4 and the inner cylinder 2 prevents the transmission belt 5 from twisting when the inner cylinder 2 vibrates up and down subsequently.

[0023] When it is necessary to shake off the salt grains on the cowhide, the opening and closing door on the top of the outer cylinder 1 is opened, the cowhide is placed in the inner cylinder 2, and the motor 6 is started, thereby driving the rotating block 15 and the active transmission shaft 16 to rotate, and the transmission belt 5 drives the driven transmission shaft 4 to rotate, thereby driving the inner cylinder 2 to rotate. When the inner cylinder 2 rotates, the cowhide inside can be shaken off, thereby shaking off the salt grains on the cowhide, allowing the salt grains to pass through the through holes 3 until they are separated from the cowhide, and completing the shaking off of the salt grains on the cowhide;

[0024] The inner side of the inner tube 2 is provided with a plurality of anti-edge structures, which are used to prevent the cowhide from adhering to the inner wall of the inner tube 2.

[0025] Refer to the attached Figure 3 The anti-sticking structure is composed of multiple rotating rods 8 that are rotatably connected to the inside of the inner cylinder 2 and close to the inner wall. Through the setting of the rotating rods 8, when the cowhide is pressed against the inner wall of the inner cylinder 2 due to centrifugal force, the rotating rods 8 can be rotated to cause the cowhide to continue to slide when in contact with the rotating rods 8, avoiding piles of salt on the side wall of the inner cylinder 2. This ensures that the salt particles on the cowhide are thrown off, and does not cause the service life of the inner cylinder 2 to be reduced due to excessive force on one side.

[0026] Refer to the attached Figure 3, a bottom piece 9 is fixed to the top of the inner cylinder 2, and a limiting groove ring 11 is fixed to the top of the bottom piece 9. A top piece 10 is provided inside the outer cylinder 1 and at the top of the limiting groove ring 11. A plurality of hemispherical bodies 12 are fixed at the bottom of the top piece 10 and at positions corresponding to the limiting groove ring 11. The hemispherical bodies 12 are made of flexible material. Through this arrangement, the hemispherical bodies 12 can continuously adjust their shapes according to the limiting groove ring 11 when rotating, thereby reducing the friction between the hemispherical bodies 12 and the limiting groove ring 11, and the material can be harder rubber, etc. When the hemispherical bodies 12 slide on the limiting groove ring 11, they can push the bottom piece 9 and the inner cylinder 2 up and down, and a plurality of springs 13 are installed between the top piece 10 and the bottom piece 9, and the spring 13 is slidably connected to one of the bottom piece 9 and the top piece 10;

[0027] When the inner cylinder 2 rotates, it can drive the bottom piece 9 and the limiting groove ring 11 to rotate, and make the spacing groove on the limiting groove ring 11 constantly contact with the hemisphere 12, so that the limiting groove ring 11, the bottom piece 9 and the inner cylinder 2 move upward or downward. Through the setting of the spring 13, the spring 13 can drive the inner cylinder 2 to reset, thereby generating a vibration effect in the inner cylinder 2, thereby enhancing the effect of the cowhide shaking off the salt particles.

[0028] Furthermore, a funnel bin 14 is provided at the bottom of the inner cylinder 2. The funnel bin 14 is funnel-shaped, and the collected salt particles slide downward. The diameter of the funnel bin 14 is larger than the diameter of the inner cylinder 2, thereby ensuring that when the funnel bin 14 collects salt particles, the salt particles on the side of the inner cylinder 2 can also be collected at the same time. A leakage pipe 7 is fixed to the bottom of the funnel bin 14, and the leakage pipe 7 passes through the outer cylinder 1 and extends to the bottom of the outside of the outer cylinder 1. Through the setting of the leakage pipe 7, the device can guide the salt particles and discharge them to the outside of the device.

[0029] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
