[0002] In current leather slitting devices, when replacing the unwinding roller and the slitting roller, it is generally necessary to first remove multiple bolts, and then fix them back in place with bolts after the unwinding roller and the slitting roller have been replaced, which is quite inconvenient.

[0003] Although the prior art, application number CN202220874951.1 discloses an automatic leather cutting and slitting device, in use, the sliding plate drives the motor to move, and the sliding plate is limited by the limiting component, making it more convenient to install and disassemble the drive component; the limiting plate limits the fixed ring, making it more convenient to replace the unwinding roller and the slitting roller.

[0004] However, under the above method, the overall leather cutting and rewinding operation still requires a lot of manual operation. When changing the unwinding roller and the rewinding roller, the parts must be manually disassembled to complete the replacement operation, which is quite cumbersome. In addition, due to the weight of the leather after it is wrapped on the rewinding roller, it may be difficult for a single person to remove the rewinding roller containing the leather from the mounting groove. Therefore, this solution proposes an automatic cutting and rewinding device for color-changing leather. Utility Model Content

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This utility model is reasonably designed. By placing the leather to be rolled on the feeding roller, the free end of the leather passes through the cutting assembly and is fixed on the rolling roller. Then, under the operation of the positioning component, the rolling roller is driven to rotate. When the length of the leather on the rolling roller reaches the specified length, it is cut by the cutting assembly to roll the leather.

[0017] After being slit, the leather is driven by electric push rod one to rotate storage rack two, causing the slitting roller to continuously move in a straight line along the placement platform until it is pushed by storage rack two and falls above storage rack three.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," "provided with," and "located in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0033] Please see Figures 1-3An automatic cutting and rewinding device for color-changing leather includes an internal frame 1. An external frame 2 is fixedly connected to the side of the internal frame 1. A cutting assembly 3 for leather cutting is installed between the inner walls of one side of the external frame 2. A feeding roller 4 is installed between the inner walls of the other side of the external frame 2. A placement platform 5 is fixedly connected to the inner wall of the internal frame 1. A storage rack 6 is rotatably connected between the inner walls of the internal frame 1. A storage groove 7 is opened at the top of the storage rack 6. An electric push rod 8 is installed between the storage rack 6 and the inner wall of the internal frame 1. A rewinding roller 9 is provided at the top of the storage rack 6. One end of the rewinding roller 9 is located on the upper surface of the placement platform 5. A positioning element 10 is installed at the side end of the rewinding roller 9. A storage rack 3 11 is rotatably connected to the side of the internal frame 1. A storage groove 3 12 is opened at the top of the storage rack 3 11. An electric push rod 2 13 is installed between the storage rack 3 11 and the outer wall of the internal frame 1.

[0034] In order to make the existing technology of cutting and rolling leather more intelligent and automated, and easier to disassemble, this embodiment places the leather to be rolled on the feeding roller 4, and the free end of the leather passes through the cutting assembly 3 and is fixed on the rolling roller 9. Then, under the operation of the positioning member 10, the rolling roller 9 is driven to rotate. When the length of the leather on the rolling roller 9 reaches the specified length, it is cut by the cutting assembly 3 to roll the leather.

[0035] After being slit, the leather is driven by electric push rod 8, causing storage rack 6 to rotate. This causes the slitting roller 9 to continuously move linearly along the placement platform 5 until it is pushed by storage rack 6 and falls above storage rack 11. Finally, driven by electric push rod 13, storage rack 11 rotates again, bringing the slitting roller 9 containing the leather closer to the ground, making it easier and more convenient for personnel to transport the leather.

[0036] Please see Figures 1-2 The cutting assembly 3 includes a base plate 31 fixedly connected to the inner wall of one side of the outer frame 2. The upper end of the base plate 31 is provided with a dividing hole 32. Cylinders 33 are fixedly connected to the top two sides of the base plate 31. Two symmetrically distributed guide rods 34 are installed between the inner walls of the cylinders 33. A pneumatic slide 35 is movably installed at the outer end of the guide rods 34. A cutting blade assembly is installed at the lower end of the pneumatic slide 35.

[0037] During use, when the length of the leather on the slitting roller 9 reaches the specified length, the pneumatic slide 35 is driven by the cylinder 33 to move laterally on the surface of the guide rod 34, so that the cutting blade assembly below can cut the leather inside the slitting hole 32.

[0038] Please see Figures 1-2 A storage rack 36 is rotatably connected between the cylinder 33 and the inner wall of the outer frame 2. A storage slot 37 is provided at the top of the storage rack 36. A motor 38 is installed at the outer end of the outer frame 2. The output shaft of the motor 38 is fixedly connected to the transmission shaft of the storage rack 36.

[0039] During use, this solution allows personnel to pre-load the splitting roller 9 inside the storage slot 1 37. After one splitting roller 9 has finished splitting the leather, the personnel can drive the motor 1 38 to cause the storage rack 1 36 to rotate until the splitting roller 9 gradually slides into the storage slot 2 7 on the lower side due to tilting. This eliminates the need for manual replacement by disassembling parts, saving manpower and increasing work efficiency.

[0040] Please see Figure 1 and Figure 3 The positioning component 10 includes a second cylinder 1001 mounted on the side wall of the built-in frame 1. Two symmetrically distributed guide rods 1002 are mounted between the inner walls of the second cylinder 1001. A pneumatic slide 1003 is movably mounted on the outer end of the guide rod 1002. A connecting plate 1004 is fixedly connected to the upper end of the pneumatic slide 1003. A motor 1005 is mounted on the upper end of the connecting plate 1004. The output shaft of the motor 1005 is engaged with the winding roller 9.

[0041] More specifically: the outer end of the output shaft of the second motor 1005 is provided with a plurality of evenly distributed limiting grooves 1006, the side end of the slitting roller 9 is provided with an insertion hole 91, and a plurality of limiting blocks 92 that match the limiting grooves 1006 are fixedly connected to the inner wall of the insertion hole 91.

[0042] During the use of this solution, when the sliding roller 9 is replaced, the operator first drives the pneumatic slide table 1003 to slide on the surface of the guide rod 1002 under the action of the cylinder 1001, so that the connecting plate 1004 drives the output shaft of the motor 1005 to slide to the outside of the insertion hole 91. At this time, the sliding roller 9 is no longer limited and can rotate and move freely.

[0043] When the leather needs to be rewound, the rewinding roller 9 cannot move due to the limitation of the storage groove 7. At this time, the operator controls the pneumatic slide 1003 to drive the connecting plate 1004 back to the initial position. At the same time, the output shaft of the motor 1005 is inserted into the insertion hole 91. Since the position of the rewinding roller 9 is limited, the rewinding and rotation collection operation of the rewinding roller 9 can be realized by driving the motor 1005.

[0044] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
