[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Referring to Figure 1 - Figure 3 An embodiment provided by the utility model: a round cutting knife automatic grinding mechanism of a cloth drawing machine, comprising a cutting knife cover shell 1, the outer wall of the cutting knife cover shell 1 is fixedly connected with a grinding tool support 2, the inside of the grinding tool support 2 is provided with a grinding tool cylinder 3, the input end of the grinding tool cylinder 3 is screw-connected with a cylinder air nozzle 4, the output end of the grinding tool support 2 is fixedly connected with a grinding tool wheel 5, the outer wall of the grinding tool wheel 5 is attached to the outer wall of the grinding tool support 2, the inside of the cutting knife cover shell 1 is provided with a round blade 7, the outer wall of the grinding tool wheel 5 is attached to the outer wall of the round blade 7, the outer wall of the cutting knife cover shell 1 is provided with a driving assembly, and the driving assembly is used to drive the round blade 7 to rotate to cut cloth.

[0019] Specific, cutter cover 1 and grinding tool holder 2 fixedly connected, grinding tool holder 2 inside the grinding tool cylinder 3 play a supporting role, by starting grinding tool cylinder 3 compressed air through the cylinder air nozzle 4 into the grinding tool cylinder 3 inside, and then through the push piston grinding wheel 5 driven to move, grinding wheel 5 adhere to the surface of the round blade 7, polishing round blade 7, without disassembling round blade 7, without preparation tools, improve the grinding efficiency of round blade 7, save the effect of factory use cost.

[0020] With reference to Figure 1 - Figure 3 , drive assembly includes motor 6, the outer wall of motor 6 is fixedly connected to the outer wall of cutter cover 1, and the output end of motor 6 is arranged on the inner wall of round blade 7.

[0021] Specifically, the motor 6 drives the round blade 7 to rotate, so that the round blade 7 can be polished on the outer wall of the grinding wheel 5, and the motor 6 drives the round blade 7 to rotate while cutting the cloth.

[0022] With reference to Figure 1 - Figure 3 , grinding tool holder 2 is used for fixing grinding tool cylinder 3.

[0023] Specifically, the grinding tool holder 2 is fixed on the outer wall of the cutter cover 1, and the grinding tool cylinder 3 is fixed in the grinding tool holder 2, so that the grinding tool holder 2 and the cutter cover 1 support and fix the grinding tool cylinder 3.
