Description

Technical Field

[0001] This application relates to the technical field of slitting machines, and more particularly to a leather slitting machine. Background Technology

[0002] A leather slitting machine is a device that cuts, slits, or divides leather. It can divide thick leather into multiple layers or leather pieces of specific sizes to meet different production needs.

[0003] In related technologies, a leather slitting machine includes a frame, on which a feeding mechanism, a slitting mechanism, and a pressing mechanism are provided. The feeding mechanism is used to move the leather into the slitting mechanism, the pressing mechanism is used to press the leather, the slitting mechanism is used to slitting the leather, and the pressing mechanism includes a pressing cylinder and a pressing block. The pressing block is set on the pressing cylinder, and the pressing cylinder can press the leather.

[0004] Initially, workers need to manually move the leather to the pressing cylinder so that the pressing block can press the leather down. If the leather is wide, it is easy for the leather to shift to one side during the process of moving the leather, which will result in the leather being cut to the wrong width by the subsequent slitting mechanism and affect the normal use of the leather. Summary of the Invention

[0005] To address the issue of leather shifting to one side when workers move it, this application provides a leather slitting machine.

[0006] This application provides a leather slitting machine, which adopts the following technical solution: A leather slitting machine includes a frame with a pressing mechanism. The pressing mechanism includes a movable structure and a pressing plate. The pressing plate is mounted on the movable structure, which is mounted on the frame. The movable structure drives the pressing plate to move on the frame. The pressing plate has a receiving groove for inserting leather. A filler is provided in the receiving groove to prevent the leather from detaching from the receiving groove.

[0007] By adopting the above technical solution, the worker first inserts the leather into the receiving groove, then the filling material restricts the leather in the receiving groove, and finally the driving moving structure moves the pressing plate, so that the pressing plate can move the leather synchronously, reducing the problem of the leather shifting to one side when the worker pulls the leather, thereby improving the stability of cutting the leather.

[0008] Optionally, the filling component includes an inflatable block and a filling rod, the filling rod being disposed within a receiving groove, the inflatable block being disposed on the filling rod, and the inflatable block being used to drive the leather to abut against the groove wall of the receiving groove.

[0009] By adopting the above technical solution, the workers insert the leather into the receiving groove, and then fill the air block with gas. By setting the air block on the filling rod, the air block can abut against the leather, reducing the possibility of the leather falling out of the receiving groove.

[0010] Optionally, the inflatable block has a perforation, and the filling material has a slidable baffle for sealing the perforation; when the baffle does not seal the perforation, the gas in the inflatable block compresses the surface of the leather away from the ground at the perforation.

[0011] By adopting the above technical solution, workers can ensure that the baffle seals the perforation, preventing gas leakage from the air block and allowing it to stably contact the leather. When workers slide the baffle, leaving the perforation unsealed, air can leak out from the perforation, continuously compressing the leather surface away from the ground to secure it. Simultaneously, the air from the air block can clean the leather surface, reducing the risk of debris contaminating the leather and affecting subsequent cutting.

[0012] Optionally, the baffle is slidably connected to the frame, and the baffle has a groove for inserting an inflatable block. The sliding path of the baffle on the frame is less than the moving path of the moving structure driving the pressing plate. When the inflatable block is inserted into the groove, the baffle is relatively fixed on the inflatable block.

[0013] By adopting the above technical solution, the baffle is slidably connected to the frame and the pressure plate. When the pressure plate moves on the frame, it can drive the baffle to move. In addition, the sliding path of the baffle on the frame is smaller than the moving path of the pressure plate driven by the moving structure. This restricts the baffle on the frame, allowing it to slide on the pressure plate. As a result, the baffle does not block the air block, thus achieving the compression and fixation of the leather by the air block.

[0014] Optionally, the frame is provided with a limiting rod for placing leather, and a limiting ring is slidably connected to the limiting rod for separating different types of leather.

[0015] By adopting the above technical solution, the leather can be wrapped around the limiting rod, reducing the possibility of the leather detaching directly from the frame, preventing the cut leather from falling directly to the ground, and reducing the chance of the leather getting dusty.

[0016] Optionally, a limiting groove is provided on the limiting rod, and a limiting airbag is provided in the limiting groove; when the limiting airbag is inflated, the limiting airbag abuts against the inner wall of the limiting ring.

[0017] By adopting the above technical solution, after the limiting airbag is inflated, it abuts against the inner wall of the limiting groove, so that the limiting ring can be fixed on the limiting rod, reducing the movement of the limiting ring, so that the limiting ring can stably segment the leather.

[0018] Optionally, the frame is provided with a rotation drive component, which is used to drive the limiting rod to rotate. The inner wall of the limiting ring is provided with a movable hole, and a stop strip is slidably connected in the movable hole. When the limiting airbag is inflated, the stop strip abuts against the side of the leather away from the limiting rod.

[0019] By adopting the above technical solution, the limiting airbag is inflated, which allows the limiting airbag to move the stop strip. The stop strip then abuts against the side of the leather away from the limiting rod, thus fixing the leather and the limiting rod together. This allows the limiting rod to move the leather. In addition, the rotating drive component can rotate the limiting rod, allowing it to stably move the leather. This enables the leather to be wrapped and rolled up on the limiting rod for easy storage.

[0020] Optionally, a fixing groove is provided on the wall of the movable hole, and a fixing spring is provided in the fixing groove. The fixing spring drives the stop bar to move in the direction of the limiting rod.

[0021] By adopting the above technical solution, the stop strip is driven by a fixed spring to move towards the limiting rod, allowing the stop strip to stably abut against the leather and reducing the possibility of the leather moving on the limiting rod. When leather of different thicknesses is placed on the limiting rod, the limiting airbag inflates, causing the limiting airbag to move the stop strip, allowing the stop strip to protrude from the moving hole and abut against the leather. If the leather is thin, the fixed spring drives the stop strip to move towards the limiting rod, allowing the stop strip to exert force on the limiting airbag, thus allowing the stop strip to abut against the leather, achieving the function of limiting leather of different thicknesses.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The worker first inserts the leather into the receiving slot, then the filling material holds the leather within the slot. Finally, the driving mechanism moves the pressing plate, allowing the pressing plate to move the leather synchronously. This reduces the problem of the leather shifting to one side when the worker pulls it, thus improving the stability of cutting the leather.

[0023] Workers ensure the baffle seals the perforation, preventing air leakage and allowing the air block to stably press against the leather. When the baffle is slid open, allowing air to escape, it continuously compresses the leather surface away from the ground, securing it. Simultaneously, the air from the air block cleans the leather surface, reducing the risk of contamination and impairing subsequent cutting. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This embodiment discloses a leather slitting machine. (Refer to...) Figure 1 A leather slitting machine includes a frame 1, on which a feeding mechanism 11, a slitting mechanism 12, and a pressing mechanism 2 are provided. The feeding mechanism 11 is used to move the leather into the slitting mechanism 12, the slitting mechanism 12 is used to cut the leather, and the pressing mechanism 2 is used to press the leather so that it can be cut better by the slitting mechanism 12.

[0028] Reference Figure 1The pressing mechanism 2 includes a movable structure 21 and a pressing plate 22. The movable structure 21 includes a movable belt, which is fixedly connected to the frame 1. The pressing plate 22 is disposed on the movable belt, and the movable belt can drive the pressing plate 22 to move along the length direction of the frame 1.

[0029] Reference Figure 1 and Figure 2 A receiving groove 221 is formed on the surface of the pressing plate 22 away from the feeding mechanism 11, for inserting leather. A filler 23 is provided inside the receiving groove 221 to prevent the leather from detaching from the receiving groove 221. The filler 23 includes an inflatable block 231 and a filling rod 232. The filling rod 232 is fixedly connected to the receiving groove 221, and the inflatable block 231 is fixedly connected to the filling rod 232. An inflator 13 is provided on the frame 1 to inflate the inflatable block 231, allowing it to compress the leather and secure it within the receiving groove 221.

[0030] Reference Figure 2 The inflatable block 231 has a perforation 233 on its surface near the ground. A stop bar 14 is slidably connected to the frame 1 and can slide along the length of the frame 1. A through hole 24 is formed on the surface of the filler 23, and the stop bar 14 slides within the through hole 24, blocking the perforation 233 of the inflatable block 231. A groove 141 is formed on the surface of the stop bar 14 for the inflatable block 231 to be inserted. When the inflatable block 231 is located in the groove 141, the inflatable block 231 and the stop bar 14 can be relatively fixed, so that the stop bar 14 can be fixed on the filler 23.

[0031] Reference Figure 1 and Figure 2 The sliding path of the baffle 14 on the frame 1 is shorter than the moving path of the pressing plate 22 driven by the moving belt. When the inflation component 13 stops inflating the inflation block 231, the inflation block 231 can disengage from the groove 141. At this time, the baffle 14 only slides with the frame 1. As the moving belt continues to drive the pressing plate 22 to move, the baffle 14 will not block the perforation 233 of the inflation block 231, allowing the gas in the inflation block 231 to blow and squeeze the leather, so that the leather can be fixed on the frame 1.

[0032] Reference Figure 3 The frame 1 is equipped with a rotation drive component 31, which includes a rotation motor fixedly connected to the frame 1. A limit rod 3 is fixedly connected to the drive shaft of the rotation motor, and the limit rod 3 is used for placing the leather. When the rotation motor is started, the limit rod 3 can drive the leather to rotate.

[0033] Reference Figure 3 and Figure 4Multiple limiting rings 32 are slidably connected to the limiting rod 3, and the limiting rings 32 are used to separate multiple pieces of leather. A limiting groove 33 is formed on the outer surface of the limiting rod 3, and the limiting groove 33 extends along the length direction of the limiting rod 3. A limiting airbag 331 is fixedly connected inside the limiting groove 33, and the inflator 13 can inflate the limiting airbag 331. The limiting airbag 331 can protrude outside the limiting groove 33, so that the limiting airbag 331 abuts against the inner wall of the limiting ring 32, so that the limiting airbag 331 can restrict the movement of the limiting ring 32.

[0034] Reference Figure 5 A movable hole 321 is provided on the inner wall of the limiting ring 32. The movable hole 321 is inclined away from the ground, and the distance between the movable hole 321 and the ground gradually increases along the direction from one limiting ring 32 to another. A stop strip 322 is slidably connected inside the movable hole 321, and the stop strip 322 can protrude into the movable hole 321.

[0035] Reference Figure 3 and Figure 5 When the inflator 13 inflates the limiting airbag 331, the limiting airbag 331 can abut against the inner wall of the limiting ring 32, causing the limiting airbag 331 to push the stop strip 322 to move, allowing the stop strip 322 to protrude from the moving hole 321. At this time, the leather can be located between the stop strip 322 and the limiting rod 3.

[0036] Reference Figure 5 The moving hole 321 has a receiving groove 323 on its wall, which allows the stop strip 322 to slide vertically. A fixing groove 324 is formed on the groove wall of the receiving groove 323 away from the ground. A fixing spring 325 is fixedly connected in the fixing groove 324, and the fixing spring 325 abuts against the stop strip 322. When the stop strip 322 moves from the moving hole 321 into the receiving groove 323, the fixing spring 325 can drive the stop strip 322 to move, allowing the stop strip 322 to slide vertically. This causes the stop strip 322 to press the leather away from the surface of the limiting rod 3, thus fixing the leather between the limiting rod 3 and the stop strip 322.

[0037] Reference Figure 3 and Figure 4 After the leather is cut, the staff closes the inflator 13, so that the inflator 13 does not inflate the limiting airbag 331, so that the limiting airbag 331 can be located in the limiting groove 33. At this time, there is a gap between the leather and the limiting rod 3, so that the leather can be taken out from the limiting rod 3.

[0038] The implementation principle of a leather slitting machine according to an embodiment of this application is as follows: First, the worker places the leather in the receiving groove 221. Then, the worker starts the inflator 13 to inflate the inflatable block 231, so that the inflatable block 231 can press against the leather, allowing the pressing plate 22 to move the leather. The worker starts the moving belt, and after the pressing plate 22 moves the leather to a suitable position, the worker stops the inflator 13 from inflating the inflatable block 231, allowing the inflatable block 231 to detach from the groove 141. As the moving belt continues to move, the baffle 14 will no longer block the perforation 233, allowing the gas in the inflatable block 231 to escape from the perforation 233, allowing the leather to detach from the receiving groove 221. At this time, the worker starts the inflator 13 again to inflate the inflatable block 231, allowing the gas to squeeze the leather from the perforation 233.
