Abstract
Description
Technical Field
[0001] This utility model relates to the field of leather drum technology, specifically to an environmentally friendly structure for quantitatively adding enzymatic hydrolysants to leather drums. Background Technology
[0002] In existing technology, raw hides are turned over in a drum during the leather making process (such as for washing, pickling, tanning, and dyeing) or the hides are cleaned in the drum (by turning them over together with fine sawdust). The drum is an important piece of equipment widely used in tanneries. It is a wooden cylinder with protrusions or lifting plates inside. Leather can be processed in batches simultaneously inside the drum. When the drum is driven to rotate by a motor, the hides inside the drum are subjected to mechanical action, which accelerates the reaction process and changes the physical properties of the leather. The application range of the drum covers most wet processing steps in leather making as well as dry softening and napping.
[0003] Existing leather drums require the addition of enzymatic hydrolysants when cleaning leather. However, it is difficult to accurately control the dosage when manually adding the hydrolysants, and manual addition usually involves adding a large amount of hydrolysants at once. This large amount of hydrolysants may lead to uneven mixing and clumping, which affects the cleaning of the leather. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides an environmentally friendly structure for quantitatively adding enzymatic hydrolysants to leather drums.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] An environmentally friendly leather drum enzymatic hydrolysant quantitative addition structure includes a drum body, with a connecting shaft and a positioning shaft fixedly connected to both sides of the drum body, and support columns provided on both sides of the drum body. The two support columns are respectively sleeved on the outside of the positioning shaft and the connecting shaft and are movably connected to the positioning shaft and the connecting shaft through rolling bearings. A cover plate is provided on the front side of the drum body, and a feeding box is provided on the rear side of the drum body. A feeding mechanism is provided inside the feeding box.
[0007] The feeding mechanism includes a discharge pipe located at the rear of the drum body. The discharge pipe is fixedly connected to the feeding box. A stop block is embedded inside the feeding box. A through groove is opened on both sides of the stop block. A stop rod is provided at the rear of the stop block. The rear end of the stop rod extends to the outside of the feeding box and slides with the feeding box. A rubber one-way valve is provided inside the discharge pipe.
[0008] Preferably, one of the support columns has a horizontal plate on its front side, and a bracket is provided at the bottom of the horizontal plate.
[0009] Preferably, a servo motor is provided on one side of the drum body, the servo motor is located on the top of the bracket, and the output end of the servo motor is movably connected to the vertical plate through a rolling bearing.
[0010] Preferably, a first sprocket and a second sprocket are provided on one side of the drum body. The first sprocket and the second sprocket are respectively sleeved on the output end of the servo motor and the outside of the positioning shaft. A chain is provided on the outside of the first sprocket and the second sprocket. The first sprocket and the second sprocket are connected by a chain drive.
[0011] Preferably, the feeding mechanism further includes a lifting plate, which is located on the rear side of the feeding box and is fixedly connected to the rear end of the stop bar.
[0012] Preferably, a first abutment plate is provided on the rear side of the feeding box, and the first abutment plate is located on the rear side of the lifting plate.
[0013] Preferably, the feeding box is provided with two feeding pipes on the rear side.
[0014] Preferably, the feeding box is provided with two springs on the rear side.

[0026] Example 1
[0027] like Figures 1-4 As shown, an environmentally friendly leather drum enzymatic hydrolysant quantitative addition structure includes a drum body 1, with a connecting shaft 2 and a positioning shaft 3 fixedly connected to both sides of the drum body 1, and support columns 4 provided on both sides of the drum body 1. The two support columns 4 are respectively sleeved on the outside of the positioning shaft 3 and the connecting shaft 2 and are movably connected to the positioning shaft 3 and the connecting shaft 2 through rolling bearings. A cover plate 5 is provided on the front side of the drum body 1, and a feeding box 6 is provided on the rear side of the drum body 1. A feeding mechanism is provided inside the feeding box 6.
[0028] The feeding mechanism includes a discharge pipe 7, which is located on the rear side of the drum body 1. The discharge pipe 7 is fixedly connected to the feeding box 6. A stop block 8 is embedded inside the feeding box 6. A through groove 9 is opened on both sides of the stop block 8. A stop rod 14 is provided on the rear side of the stop block 8. The rear end of the stop rod 14 extends to the outside of the feeding box 6 and slides with the feeding box 6. A rubber one-way valve 10 is provided inside the discharge pipe 7.
[0029] The feeding mechanism also includes a lifting plate 17, which is located on the rear side of the feeding box 6. The lifting plate 17 is fixedly connected to the rear end of the stop bar 14. A first abutting plate 18 is provided on the rear side of the feeding box 6. The first abutting plate 18 is located on the rear side of the lifting plate 17. Two feeding pipes are provided on the rear side of the feeding box 6. Two springs 19 are provided on the rear side of the feeding box 6. Hydraulic rods 20 are provided on the top of the two support columns 4. A lifting frame 21 is provided on the top of the two hydraulic rods 20. A second abutting plate 22 is fixedly connected to the bottom of the lifting frame 21.
[0030] The workflow of this embodiment is as follows: When the drum body 1 rotates, the feeding box 6 and the first contact plate 18 also rotate. When the first contact plate 18 contacts the second contact plate 22, the second contact plate 22 and the first contact plate 18 are pressed together, causing the first contact plate 18 to be squeezed. The first contact plate 18 presses down and drives the baffle 14 to penetrate into the feeding box 6. At this time, the baffle moves down and squeezes the rubber one-way valve 10, causing the enzymatic hydrolysate inside the baffle to be discharged. Similarly, when the first contact plate 18 is not in contact with the second contact plate 22, the spring 19 rebounds and causes the baffle 14 and the stop block 8 to return to their original positions. At this time, the enzymatic hydrolysate re-enters the stop block 8 to facilitate the next feeding operation. The user can adjust the hydraulic rod 20 to drive the second contact plate 22 to move up and down, thereby changing the degree of squeezing and the amount of medicine fed.

The output end of the servo motor 12 is movably connected to the vertical plate through a rolling bearing. A first sprocket 15 and a second sprocket 16 are provided on one side of the drum body 1. The first sprocket 15 and the second sprocket 16 are respectively sleeved on the outside of the output end of the servo motor 12 and the positioning shaft 3. A chain is provided on the outside of the first sprocket 15 and the second sprocket 16. The first sprocket 15 and the second sprocket 16 are connected by a chain drive.
[0033] The workflow of this embodiment is as follows: the servo motor 12 drives the first sprocket 15 and the second sprocket 16 to rotate, the second sprocket 16 rotates and drives the positioning shaft 3 to rotate, thereby causing the drum body 1 to rotate, and the rotating drum body 1 thoroughly cleans the leather.
