Description

Technical Field

[0001] This utility model relates to the technical field of leather dyeing equipment, specifically to a leather dyeing device. Background Technology

[0002] Leather processing is a complex and meticulous process that aims to transform animal hides into durable and beautiful finished leather. The entire process can be roughly divided into three main stages: preparation, tanning, and finishing.

[0003] One step in the finishing stage is dyeing, one type of which uses low-speed immersion dyeing. Currently, leather dyeing equipment typically has several fixed guide rollers installed in the dyeing tank, but the immersion time varies depending on the type of leather. Currently, the immersion time is generally controlled by adjusting the traction speed, but this speed variation may not be suitable for other processes. Therefore, the current practice is to squeeze out the water and directly roll up the leather after dyeing, then move it to the fatliquoring and drying equipment for further processing. This results in poor flexibility and applicability of leather dyeing equipment with fixed guide rollers. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the Invention

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

[0015] Please see Figure 1-7 This utility model provides a technical solution: a leather dyeing device, including a pool body 1 and an adjustable steering mechanism 2; A top frame 3 is provided on the upper surface of the pool body 1. Several first screw holes 4 are evenly opened on the upper surface of both sides of the top frame 3. A drain outlet 5 is provided on one side of the bottom of the pool body 1 to realize the discharge of dye waste liquid. The adjustable steering mechanism 2 includes a bracket, an upper steering roller 201, and a lower steering roller 202. The bracket includes a horizontal plate 203, an extension plate 204, a support 205, and a vertical rod 206. Extension plates 204 extend outward from both ends of the horizontal plate 203. A support 205 is provided on the upper surface of the extension plate 204 near one end of the horizontal plate 203. The two ends of the upper steering roller 201 are rotatably connected to the support 205 via a central shaft. Two first reinforcing plates 212 are provided on the outer side of the support 205. The bottom of the first reinforcing plates 212 is connected to the upper surface of the extension plate 204. The first reinforcing plates 212 ensure the structural strength of the support 205, thereby ensuring the stability of the upper steering roller 201. The extension plate 204 has two first reinforcing plates 212. The first connecting hole 207 is located in a position corresponding to two first screw holes 4 and is fastened together with bolts. A vertical rod 206 is provided on the lower surface of the extension plate 204 near the end of the horizontal plate 203. A guide groove 208 is provided on the vertical rod 206 along its length. Several through second connecting holes 209 are symmetrically provided on both sides of the vertical rod 206 and at the guide groove 208. The bottom ends of the two vertical rods 206 are connected by a connecting plate 214 to ensure the stability and structural strength of the entire support. A second reinforcing plate 215 is provided on both sides of the top of the vertical rod 206. The upper surface of the second reinforcing plate 215 is connected to the corresponding extension plate 204 to ensure the structural strength of the vertical rod 206, thereby ensuring the stability of the lower steering roller 202. The lower guide roller 202 is connected to the slider 210 at both ends through the central shaft. Two second screw holes 211 are opened on each side of the slider 210. The slider 210 is slidably set in the guide groove 208 of the upright 206. The second screw holes 211 correspond to two of the second connecting holes 209 and are fastened together by bolts. Both the support 205 and the slider 210 are equipped with bearing sleeves 213. The upper steering roller 201 is connected to the bearing sleeve 213 of the support 205 through the central shaft, and the lower steering roller 202 is connected to the bearing sleeve 213 of the slider 210 through the central shaft. The smoothness of the rotation of the upper steering roller 201 and the lower steering roller 202 is ensured by the cooperation of the bearing sleeves 213.

[0016] Installation method and operating principle: Several first screw holes 4 are equidistantly drilled on both sides of the top frame 3 on the upper surface of the pool body 1. Then, the adjustable steering mechanism 2 is assembled. First, a horizontal plate 203 is machined. Extension plates 204 are integrally formed at both ends of the horizontal plate 203. The extension plates 204 have two first connecting holes 207. The distance between two adjacent first connecting holes 207 is an integer multiple of the distance between two adjacent first screw holes 4 drilled on the top frame 3, ensuring that the first connecting holes 207 and the two first screw holes 4 can be smoothly aligned when the extension plates 204 are installed. Next, the support 205 and the first reinforcing plate 212 are welded to the upper surface of the extension plate 204, and the top of the upright and the second reinforcing plate 215 are welded to the lower surface of the extension plate 204. The upright 206 has a guide groove 208 along its length. Several second screw holes 211 are equally spaced through the guide groove 208 on both sides of the upright 206. The distance between two adjacent second screw holes 211 is the same as the distance between two second screw holes 211 on the side of the slider 210, ensuring smooth alignment. The upper steering roller 201 is connected to the bearing sleeves 213 of the two supports 205 via a central shaft. Simultaneously, the central shaft of the lower steering roller 202 is connected to the bearing sleeve 213 of the slider 210. The slider 210 is then placed into the guide groove 208 of the upright 206. Finally, the bottom ends of the two uprights 206 are connected via a connecting plate 214, completing the assembly of the adjustable steering mechanism 2. In use, the upright 206, connecting plate 214, and lower steering roller 202 are placed into the pool body 1. The distance between the two adjustable steering mechanisms 2 is adjusted according to the type of leather. Bolts are passed through the first connecting hole 207 of the extension plate 204 and fastened to the corresponding first screw hole 4 of the top frame 3 to fix the bracket. At the same time, the height of each lower steering roller 202 is adjusted. After the height is determined, bolts are passed through the second connecting hole 209 and fastened to the second screw hole 211 of the slider 210 to position the lower steering roller 202 and complete the installation. First, the leather is guided into the pool body 1 by the upper steering roller 201 of one adjustable steering mechanism 2. Then, it is turned by the lower steering roller 202 of each adjustable steering mechanism 2. Finally, it is turned by the upper steering roller 201 of the other adjustable steering mechanism 2 and leaves the pool body 1. The entire process is traction of the leather by the winding device at the end of the processing line.This utility model has a reasonable structure. Several adjustable steering mechanisms 2 are installed inside the pool body 1. The lower steering roller 202 of the adjustable steering mechanism 2 is connected to the guide groove 208 of the upright rod 206 through the slider 210 and fastened with bolts. Thus, the height of each lower steering roller 202 can be adjusted according to different leathers, greatly improving flexibility. At the same time, the adjustable steering mechanism 2 is also fastened to the top frame 3 on the upper surface of the pool body 1 through the extension plate 204 and bolts. The number of adjustable steering mechanisms 2 can be increased or decreased according to different leathers (dozens of adjustable steering mechanisms 2 can be installed to increase the stroke). The distance between two adjustable steering mechanisms 2 can also be adjusted, thereby increasing the number of turns and the soaking stroke, further improving flexibility and applicability.
