[0014] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.
[0015] like Figure 1 and Figure 2 As shown, an artificial decorative leather cutting device includes a frame 1, a cutting table 2 is connected to the frame 1, and a cutting head frame is arranged above the cutting table 2, wherein the cutting head frame moves left and right on the cutting table 2 through a moving device above the frame 1 according to the width requirement of the leather customization. In this embodiment, the cutting head frame includes a cutting cover 3, a driving shaft 4 is connected to the lower part of the cutting cover 3, one end of the driving shaft 4 is connected to the cutting cover through a bearing seat 1, a cutting wheel 5 is connected to the driving shaft 4 through a key block, a working motor 6 is installed outside the cutting cover 3, the working motor 6 is directly connected to the other end of the driving shaft 4, the driving shaft 4 is driven by the working motor 6, and the cutting wheel 5 is driven to rotate, a cutting groove 7 is processed on the cutting table 2, and the outer circumferential surface of the cutting wheel 5 protrudes from the bottom of the cutting cover 3, so that the cutting wheel 5 can completely cut through the leather during the leather cutting process.
[0016] The cutting cover 3 is provided with chip removal holes 8 on both sides above. The chip removal holes 8 are designed to be long strip holes, which are conducive to reducing blockage. The sides of the chip removal holes 8 are connected to negative pressure boxes 9, which cover the chip removal holes 8. An air pipe 10 is installed on the negative pressure box 9, which is connected to an external fan. After negative pressure is introduced, the fiber debris in the cutting cover 3 is absorbed. The bottom periphery of the cutting cover 3 is connected with a rubber skirt 11.
