Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, and in particular to a stain-resistant, high-gloss glossy leather rolling device. Background Technology

[0002] The stain-resistant, high-gloss glossy leather rolling device is a specialized piece of equipment for leather post-processing. Its core function is to give leather both stain resistance and a high-gloss finish through a rolling process. First, the leather substrate is cleaned or pre-treated for stain resistance. Then, rollers with high-precision polishing textures are used to roll and calender the leather surface. This creates a dense, smooth, glossy structure to enhance shine, while also allowing stain-resistant components to adhere evenly or integrate into the surface layer. The final product is glossy leather that combines stain resistance, abrasion resistance, and a high visual appeal.

[0003] However, some traditional devices cannot quickly replace the pressure rollers. When production needs are switched to different specifications or textures of stain-resistant high-gloss leather, replacing the pressure rollers often requires disassembling multiple fixed parts and repeatedly adjusting the positioning. The operation process is cumbersome and time-consuming, affecting the flexibility of the production rhythm. On the other hand, some devices lack pressure roller cleaning devices or rely solely on static scrapers for cleaning. Residual stain-resistant coatings, lint, or tiny impurities on the leather surface will adhere to the pressure roller surface. These residues will be transferred to the subsequent leather surface as the pressure roller rotates, resulting in defects such as spots and gloss breaks in the finished product.

[0026] A reset spring 23 is fixed inside the pressure roller mounting base 4. A pressing block 22 is slidably connected inside the pressure roller mounting base 4. The pressing block 22 is sleeved inside the reset spring 23. The top of the reset spring 23 is fixedly connected to the pressing block 22. Two fixing clips 24 are fixedly connected to the upper part of one side of the pressure roller base 5.

[0027] Specifically, the fixing clip 24 can be inserted into the groove in the pressure roller mounting seat 4 and compress the mounting seat. After the fixing clip 24 is in place, under the action of the return spring 23, the pressing block 22 moves upward and is inserted into the notch on the fixing clip 24 to achieve the fixing effect.

[0028] A rotating shaft 12 is rotatably connected to the middle of the frame 1, and a second motor 13 is rotatably connected to the other end of the rotating shaft 12. The upper pressure roller 11 is sleeved on the outside of the rotating shaft 12.

[0029] Specifically, the second motor 13 drives the rotating shaft 12 to rotate, and the upper pressure roller 11 rotates under the action of the rotating shaft 12.

[0030] A first motor 3 is fixedly connected to one side of the frame 1. The first motor 3 is fixedly connected to the drive shaft 15. A water collection tank 19 is fixedly connected inside the frame 1. A brush 20 is fixedly connected inside the frame 1. The brush 20 is made of nylon bristles.

[0031] Specifically, the first motor 3 drives the drive shaft 15 to rotate. Under the action of the drive shaft 15, the cleaning belt 16 rotates around the drive shaft 15 and the driven shaft 14. When the cleaning belt 16 passes over the brush 20, the nylon bristles on the brush 20 can clean the water and dirt on the surface.

[0032] A spray pipe 17 is fixedly connected inside the frame 1, and multiple nozzles 18 are fixedly connected to the outer wall of one side of the spray pipe 17.

[0033] Specifically, external water enters the spray pipe 17 and is sprayed onto the surface of the cleaning belt 16 through the nozzle 18.

[0034] A sponge block 21 is slidably connected to the middle of the cleaning belt 16, and both ends of the sponge block 21 are fixedly connected to the frame 1.

[0035] Specifically, the sponge block 21 can absorb moisture from the surface of the cleaning strip 16.

[0036] A cylinder 6 is fixedly connected to the bottom of the frame 1. A piston rod 7 is slidably connected inside the cylinder 6. A bearing seat 8 is fixedly connected above the piston rod 7. A lower pressure roller 10 is rotatably connected inside the bearing seat 8. The lower pressure roller 10 is a soft pressure roller with a polyurethane elastomer on the outside.

[0038] A take-up roller 2 is rotatably connected to the middle of the other end of the frame 1.

[0039] Specifically, the rolled leather is wound outside the take-up roller 2.

[0040] Working principle: After the leather to be rolled enters the frame 1, the cylinder 6 drives the piston rod 7 to move upward, causing the bearing seat 8 to rise axially along the guide shaft 9, so that the lower pressure roller 10 inside the bearing seat 8 moves upward and cooperates with the upper pressure roller 11 to press the leather; then, the second motor 13 drives the rotating shaft 12 to rotate, so that the upper pressure roller 11 sleeved on the outside of the rotating shaft 12 rotates synchronously, and together with the lower pressure roller 10, rolls the leather to form a stain-resistant, high-gloss glossy surface effect; during the rolling process, the first motor 3 drives the drive shaft 15 to rotate, so that the cleaning belt 16 rotates around the drive shaft 15 and the driven shaft 14. The protrusions on the cleaning belt 16 make close contact with the upper pressure roller 11 to clean its upper surface; at the same time, the spray pipe 17 sprays through the nozzle 18 Water is sprayed onto the surface of the cleaning belt 16 for initial cleaning. Wastewater is collected by the water collection tank 19 and then passes through the brush 20 to remove water and stains from the surface of the cleaning belt 16. The remaining moisture is then absorbed by the sponge block 21 that slides in the middle. Finally, the rolled leather is wound up by the take-up roller 2 in the middle of the other end of the frame 1. When the upper pressure roller 11 needs to be replaced, the pressing block 22 is pressed, the fixing clip 24 is released, the upper pressure roller 11 is pulled out, and the new upper pressure roller 11 is pushed into the pressure roller mounting seat 4. The pressing block 22 moves downward, and the return spring 23 is compressed until a click is heard, and the fixing is completed. At this time, under the action of the return spring 23, the pressing block 22 moves upward and gets into the notch of the fixing clip 24 to achieve fixing.
