Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to an automatic plastic skin cutting machine. Background Technology

[0002] Plastic skin (or leather) is used in the manufacture of suitcases. Plastic skin is usually cut from a large roll of raw material by a cutting machine. Because plastic skin is light, the cutting blades of existing cutting machines tend to lift the plastic skin upwards during the cutting process, which can easily lead to inaccurate dimensions of the final cut. Utility Model Content

[0030] Adsorption platform 400, air-permeable layer structure 410, air extraction device 420. Detailed Implementation

[0031] Reference Figure 1 As shown, an automatic plastic skin cutting machine 1000 provided in this embodiment of the present utility model includes a machine base 100, a feeding roller 200 and a moving mechanism 300, wherein the feeding roller 200 is wound with plastic skin 210.

[0032] The feeding roller 200 is rotatably mounted on the machine base 100. (See reference) Figures 2 to 4As shown, the moving mechanism 300 includes a first frame 310, a second frame 320, a tool holder 330, a pressure plate 340, a cutting tool 380, a first drive device 390, a second drive device 3010, a lifting mechanism 3011, and a cable chain 3013. The first frame 310 is slidably connected to the machine platform 100 and can move along the left and right directions of the machine platform 100. The second frame 320 is slidably connected to the first frame 310 and can move along the front and back directions of the machine platform 100. The tool holder 330 is slidably connected to the second frame 320 and can move along the up and down directions. The cutting tool 380 and the pressure plate 340 are connected to the tool holder 330. The lifting mechanism 3011 is used to drive the tool holder 330 to move up and down. The pressure plate 340 is used to press the plastic sheet 210. The first drive device 390 is used to drive the first frame 310 to move along the left and right directions of the machine platform 100. The second drive device 3010 is used to drive the second frame 320 to move along the front and back directions of the machine platform 100.

[0033] The moving mechanism 300 in this embodiment can drive the cutter 380 to move in the left-right, front-back, and up-down directions, which is quite flexible. During the cutting process, when the lifting mechanism 3011 drives the cutter 380 to cut downwards, the pressure plate 340 can press down on the plastic skin 210, so that the cutter 380 will not lift the plastic skin 210 upwards, which can ensure that the plastic skin 210 will not be misaligned, and the final cut size is more accurate.

[0034] Reference Figure 2 As shown, in some embodiments, the pressure plate 340 has a through hole at its center, through which the cutting tool 380 passes. The pressure plate 340 can be a disc structure. This arrangement reduces the space occupied, and the pressure plate 340 can more evenly press the plastic sheet 210. The tool holder 330 has a guide hole, and the pressure plate 340 has a vertically extending guide shaft 350. The guide shaft 350 is slidably connected to the guide hole, and a spring 360 is sleeved on the outer periphery of the guide shaft 350. The upper end of the spring 360 abuts against the tool holder 330, and the lower end of the spring 360 abuts against the pressure plate 340. When the pressure plate 340 presses the plastic sheet 210, the spring 360 is compressed. By setting the spring 360, the spring 360 can provide a pressing force on the plastic sheet 210 without excessively pressing the plastic sheet 210, thus playing a buffering role.

[0035] Reference Figure 2 As shown, in some embodiments, the upper end of the guide shaft 350 is provided with an external thread, and a nut 370 is connected to the external thread. When the lifting mechanism 3011 lifts the tool holder 330, the nut 370 will contact the tool holder 330, thereby supporting the pressure plate 340, so that the pressure plate 340 can be separated from the plastic skin 210. During the horizontal movement of the tool holder 330, the pressure plate 340 will not move along with the plastic skin 210.

[0036] Reference Figure 2As shown, in some embodiments, there are multiple guide shafts 350 and guide holes, which are arranged in a one-to-one correspondence, and the multiple guide shafts 350 are spaced apart along the circumferential direction. The guiding effect is better.

[0037] Reference Figure 1 As shown, in some embodiments, the automatic plastic sheet cutting machine 1000 further includes a pressure roller 220, which is located below the feeding roller 200 and is used to press the plastic sheet 210 downwards. This pressure roller also serves a guiding function.

[0038] In some embodiments, the automatic plastic skin cutting machine 1000 further includes an adsorption platform 400 and an air extraction device 420. The adsorption platform 400 is disposed on the machine base 100 and located below the plastic skin 210. A breathable layer structure 410 is laid on top of the adsorption platform 400, and the plastic skin 210 is placed on top of the breathable layer structure 410. The adsorption platform 400 has a plurality of upward-facing air suction holes for adsorbing the plastic skin 210. The air extraction device 420 is connected to the adsorption platform 400. When the air extraction device 420 extracts air from the air suction holes, it adsorbs the breathable layer structure 410. At the same time, since the breathable layer structure 410 is breathable, it can also adsorb the plastic skin 210, thus providing a certain fixing effect on the plastic skin 210. The breathable layer structure 410 has a certain thickness and is a soft structure for cutting by the blade 380. When the blade 380 cuts the plastic skin 210, it will also cut into part of the breathable layer structure 410, but will not completely sever the breathable layer structure 410.

[0039] In some embodiments, the breathable layer structure 410 may be made of woven fabric or plastic with vents.

[0040] Reference Figure 2 As shown, in some embodiments, the tool holder 330 is further provided with a rotation drive device 3012, which is used to drive the tool 380 to rotate around a vertical axis. The tool 380 can be configured as a disc structure, and the rotation drive device 3012 can be a motor. The rotation drive device 3012 can drive the tool 380 to change direction, thereby changing the cutting direction and making the cutting direction change more flexible.

[0041] The first driving device 390, the second driving device 3010 and the lifting mechanism 3011 mentioned above can be set as any form such as a cylinder, a linear module, or a lead screw motor. The sliding connection mentioned above can be achieved by any means such as a slide rail, a slider, a pulley, a lead screw, or a nut.
