Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, specifically to a rapid splitting device for leather processing. Background Technology

[0002] Leather is animal hide that has been denatured and is not easily perishable, obtained through physical and chemical processing such as hair removal and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and a comfortable feel. Splitting is an essential process when leather needs to be processed.

[0003] In traditional splitting operations, leather fibers and debris tend to accumulate in the gap between the blade and the feed roller. If not cleaned in time, the blockage between the blade and the feed roller will increase cutting resistance, forcing the equipment to run at a slower speed. Local stress concentration on the blade will cause microcracks to propagate, leading to fluctuations in splitting thickness and eventually triggering an automatic shutdown for detection, which affects the efficiency of splitting work. Furthermore, existing splitting machines require manual disassembly of the blades for cleaning or replacement. The operation process requires stopping the machine and manually adjusting the blade angle and pressure parameters. Each blade change takes a long time, and frequent blade changes can easily cause the accumulation of positioning errors. Utility Model Content

A blade holder 2 is slidably mounted on the frame 1, and a cutting blade 601 is provided on the blade holder 2. A first cleaning mechanism 6 for cleaning the cutting blade 601 is provided on the blade holder 2, and a second cleaning mechanism 7 for cleaning the first feeding roller 4 and the second feeding roller 5 is provided on the frame 1. The first cleaning mechanism 6 includes a movable seat 606 slidably mounted on the blade holder 2, and the blade holder... A lead screw 607 is rotatably mounted inside the frame 1. The lead screw 607 passes through the movable seat 606 and is rotatably connected to the movable seat 606. A cleaning block 608 is slidably mounted inside the movable seat 606, and the cleaning block 608 is fitted against the two sides of the cutting blade 601. The cutting blade 601 is rotatably connected to the blade holder 2 via a mounting shaft 602. A first gear 603 is sleeved on the mounting shaft 602. A first rack 604 is slidably mounted inside the blade holder 2. The second cleaning mechanism 7 includes two sets of cleaning rollers 701 rotatably mounted on the frame 1. The cleaning rollers 701 are respectively fitted to the first feeding roller 4 and the second feeding roller 5. In the first cleaning mechanism 6, the movable seat 606 and the cleaning block 608 work synchronously with the cutting blade 601 to continuously and automatically remove the fibers and debris attached to both sides of the blade. In the second cleaning mechanism 7, the cleaning rollers 701, the brush 703, and the scraper 711 act synchronously on the surfaces of the first feeding roller 4 and the second feeding roller 5 to clean the residue on their surfaces and in the gap area between the cutting blade 601. This fundamentally avoids the accumulation and blockage of debris in the gap between the blade and the feeding rollers, significantly reduces cutting resistance, and eliminates problems such as stress concentration in the cutting tool, microcrack propagation, and layer thickness fluctuation caused by blockage. It effectively prevents unplanned automatic shutdowns caused by blockage, greatly improves the continuity of equipment operation and layering efficiency. Moreover, the two sides of the cutting blade 601 are interchangeable. At the same time, the cleaning rollers 701, together with the brush 703 and the scraper 711, can complete the cleaning work synchronously during the operation of the first feeding roller 4 and the second feeding roller 5, reducing downtime and improving work efficiency.

[0028] In this embodiment, reference Figure 3 , Figure 4As shown, the cutting blade 601 is positioned with corresponding gaps to the first feeding roller 4 and the second feeding roller 5. Two sets of symmetrically distributed third cylinders 3 are fixedly mounted on the frame 1, and the blade holder 2 is fixedly connected to the output end of the piston rod of the third cylinder 3. A first slide rod 609 is fixedly mounted inside the movable seat 606, and the cleaning block 608 is slidably sleeved with the first slide rod 609. Two sets of symmetrically distributed first springs 610 are sleeved on the first slide rod 609, and the two ends of the two sets of first springs 610 are respectively connected to the cleaning block 608 and the movable seat 606. A base 606 is fixedly connected, and a first cam 611 is rotatably mounted inside the movable base 606, with the first cam 611 fitting against the cleaning block 608. A first rack 604 meshes with a first gear 603. A first cylinder 605 is fixedly mounted inside the blade holder 2, and the first rack 604 is fixedly connected to the output end of the piston rod of the first cylinder 605. The leather to be processed is clamped and pulled by the first feeding roller 4 and the second feeding roller 5, and fed into the cutting area at a uniform speed. The cutting blade 601 is precisely positioned directly above the gap between the two feeding rollers. The blade holder 2 and the cutting blade 601 are driven to slide by the third cylinder 3 fixed on the frame 1, so that the blade cuts into the leather with a preset pressure, completing the splitting. After the leather layers are split, they are output by the subsequent rollers. After a period of use, residue from the leather cutting process adheres to the cutting blade 601. At this time, the third cylinder 3 is activated, which moves the blade holder 2 and the cutting blade 601 on the blade holder 2 away from the first feeding roller 4 and the second feeding pipe. The first cylinder 605 on the blade holder 2 is activated, which moves the first rack 604 to slide. This, in conjunction with the first gear 603 meshing with it, causes the mounting shaft 602 to rotate the cutting blade 601 180 degrees, completing the switching of the working end of the cutting blade 601. The end with the residue aligns with the moving seat 606. The third cylinder 3 in the frame 1 is restarted, causing the blade holder 2 to rotate. The cutting blade 601 returns to its original position. The lead screw 607 in the blade holder 2 is driven by the motor. Under the limiting action of the blade holder 2, the moving seat 606 drives the cleaning block 608 to slide, cleaning the impurities on the surface of the cutting blade 601 that is in contact with it. The motor in the moving seat 606 drives the first cam 611 to rotate, pushing the cleaning block 608 and squeezing the first spring 610 on the first slide rod 609. With the restoring force of the first spring 610, the cleaning block 608 slides back and forth in the moving seat 606 as it slides with the moving seat 606, shaking off the impurities cleaned from the cutting blade 601.

[0029] In this embodiment, reference Figure 5 and Figure 6As shown, the second cleaning mechanism 7 also includes two sets of mounting brackets 712 fixedly mounted on the frame 1. The two sets of mounting brackets 712 are respectively arranged corresponding to two sets of cleaning rollers 701. A slide 707 is slidably mounted on the mounting bracket 712, and a rotating frame 702 is rotatably mounted on the slide 707. Two sets of symmetrically distributed brushes 703 are fixedly mounted on the rotating frame 702. A scraper 711 is fixedly mounted on the mounting bracket 712. The two sets of brushes 703 are respectively connected to the cleaning rollers 701 and... The scraper 711 is fitted together, and a second slide rod 708 is fixedly installed inside the mounting bracket 712. The slide 707 is slidably sleeved with the second slide rod 708. Two sets of symmetrically distributed second springs 709 are sleeved on the second slide rod 708. The two ends of the two sets of second springs 709 are fixedly connected to the slide 707 and the mounting bracket 712, respectively. A second cam 710 is rotatably installed inside the mounting bracket 712, and the second cam 710 is fitted with the slide 707. A rotating bracket 702 is sleeved with... The second gear 704, the slide 707 has a second rack 705 slidably installed inside it, and the second rack 705 is meshed with the second gear 704. The slide 707 has a second cylinder 706 fixedly installed inside it, and the second rack 705 is fixedly connected to the output end of the piston rod of the second cylinder 706. The two sets of cleaning rollers 701 are respectively in close contact with the surfaces of the first feeding roller 4 and the second feeding roller 5. When the first feeding roller 4 or the second feeding roller 5 rotates, the cleaning roller 701 rotates in the opposite direction. It uses friction or adhesion to remove the debris from the roller surface. The second cam 710 in the mounting frame 712 rotates under the drive of the motor, pushing the slide 707 that is in contact with it. With the cooperation of the second slide rod 708 and the second spring 709, the slide 707 drives the rotating frame 702 and the brush 703 to slide back and forth on the mounting frame 712. For cleaning the impurities adhering to the cleaning roller 701 that is in contact with it, the second cylinder 706 in the slide 707 pushes the second rack 705 to move. The second rack 705 meshes with the second gear 704 fixed on the rotating frame 702, driving the rotating frame 702 and the two sets of brushes 703 mounted on it to rotate 180 degrees, completing the position change of the two sets of brushes 703. The scraper 711 fixed on the mounting frame 712 contacts the brushes 703. As the brushes 703 slide back and forth with the slide 707, their bristles are scraped by the scraper 711, removing the debris carried by the brushes 703, achieving self-cleaning of the brushes 703, and ensuring continuous and effective cleaning capability. The cleaning of the cutting blade 601 and the cleaning of the feeding roller run synchronously and automatically during the splitting process, without the need for machine shutdown intervention.

[0030] In this embodiment, the leather to be processed is held and pulled by the first feeding roller 4 and the second feeding roller 5, and fed into the cutting area at a uniform speed. The cutting blade 601 is precisely positioned above the gap between the two feeding rollers. The blade holder 2 and the cutting blade 601 are driven to slide by the third cylinder 3 fixed on the frame 1, so that the blade cuts into the leather with a preset pressure to complete the splitting. After the leather layers are split, they are output by the subsequent rollers. After a period of use, residue from the leather cutting process adheres to the cutting blade 601. At this time, the third cylinder 3 is activated, which moves the blade holder 2 and the cutting blade 601 on the blade holder 2 away from the first feeding roller 4 and the second feeding pipe. The first cylinder 605 on the blade holder 2 is activated, which moves the first rack 604 to slide. This, in conjunction with the first gear 603 meshing with it, causes the mounting shaft 602 to rotate the cutting blade 601 180 degrees, completing the switching of the working end of the cutting blade 601. The end with the impurities aligns with the moving seat 606. The third cylinder 3 in the frame 1 is restarted, which causes the blade holder 2 to move the cutting blade 601 back to its original position. The lead screw 607 in the blade holder 2 is driven by a motor. Under the limiting action of the blade holder 2, the moving seat 606 moves the cleaning block 608 to slide, cleaning the impurities on the surface of the cutting blade 601 that is in contact with it. The motor in the moving seat 606 drives the first cam 611 to rotate, pushing the cleaning block 608. The first slide bar 609 is pressed against the first spring 610. With the restoring force of the first spring 610, the cleaning block 608 slides back and forth in the moving seat 606 as it slides with the moving seat 606, shaking off the impurities cleaned from the cutting blade 601. The two sets of cleaning rollers 701 are respectively in close contact with the surfaces of the first feeding roller 4 and the second feeding roller 5. When the first feeding roller 4 or the second feeding roller 5 rotates, the cleaning roller 701 rotates in the opposite direction, using friction or adhesion to remove the debris from the roller surface. The second cam 710 in the mounting frame 712 rotates under the drive of the motor, pushing the slide 707 that is in contact with it. With the help of the second slide bar 708 and the second spring 709, the slide 707 drives the rotating frame 702 and the brush 703 to slide back and forth on the mounting frame 712, cleaning the impurities adhering to the cleaning roller 701 that is in contact with it. The second cylinder 706 in the slide 707 pushes the second rack 705 to move. The second rack 705 meshes with the second gear 704 fixed on the rotating frame 702, driving the rotating frame 702 and the two sets of brushes 703 mounted on it to rotate 180 degrees, completing the position change of the two sets of brushes 703. The scraper 711 fixed on the mounting frame 712 contacts the brushes 703. As the brushes 703 slide back and forth with the slide 707, their bristles are scraped by the scraper 711, removing the debris carried by the brushes 703, achieving self-cleaning of the brushes 703, and ensuring continuous and effective cleaning capability. The cleaning of the cutting blade 601 and the cleaning of the feeding roller run synchronously and automatically during the splitting process, without the need for machine shutdown intervention.
