[0045] According to some embodiments of the present application, please refer to Figures 1 to 7The embodiment relates to a rotary die cutting equipment cooling and cleaning device, which comprises a die frame 1, a cutter roller 2, an anvil roller 3, an air compressor 4, an input air pipe 5, a refrigerating device 6, an output air pipe 7 and a blowing block 8, the cutter roller 2 and the anvil roller 3 are arranged on the die frame 1 in a side-by-side mode, first protection steps 21 are arranged on the two sides of the cutter roller 2, the air compressor 4 and the refrigerating device 6 are located outside the die frame 1, the blowing block 8 is arranged on the die frame 1, the refrigerating device 6 is provided with an air inlet 61 and an air outlet 62, the blowing block 8 is provided with an air inlet 81 and two air outlets 82, one end of the input air pipe 5 is connected with the air compressor 4, the other end of the input air pipe 5 is connected with the air inlet 61, one end of the output air pipe 7 is connected with the air outlet 62, the other end of the output air pipe 7 is connected with the air inlet 81, one air outlet 82 is arranged towards the first protection steps 21, and the other air outlet 82 is arranged towards the first protection steps 21 and the contact part of the anvil roller 3.

[0046] In use, the material to be cut is generally placed on the anvil roller 3, the equipment is started, the cutter roller 2 continuously cuts the material towards the anvil roller 3, and the material continuously moves, so that the cutter roller 2 uniformly cuts the material. According to actual production needs, the running speed of the equipment can be adjusted. When the production efficiency needs to be improved, the speed is increased, the cooperation of the cutter roller 2 and the anvil roller 3 is accelerated, the moving speed of the material on the anvil roller 3 is accelerated, and the cutting frequency of the cutter roller 2 on the material on the anvil roller 3 is accelerated. The same amount of material is cut, and the time required is shorter than that when the equipment is not speeded up.

[0047] The cutter roller 2 and the anvil roller 3 are arranged in parallel and are adjacent to each other, the cutter roller 2 can be arranged above the anvil roller 3, or the cutter roller 2 can be arranged below the anvil roller 3, and the first protection steps 21 are arranged on the two sides of the cutter roller 2, so as to protect the cutting edges on the cutter roller 2 and provide an additional support and protection layer for the cutting edges, thereby avoiding the cutting edges from being cracked due to overpressure.

[0048] On the one hand, the cutter roller 2 and the first protection steps 21 are in close contact, and a certain contact pressure is formed between the cutter roller 2 and the first protection steps 21. During high-speed rotation of the cutter roller 2 and the anvil roller 3, the contact pressure aggravates friction and causes local temperature rise. Due to thermal expansion and cold contraction, the first protection steps 21 expand with heat, so that the distance between the cutter roller 2 and the anvil roller 3 becomes larger. During equipment operation, the cutter roller 2 cannot contact the material on the anvil roller 3, or the cutting precision of the cutter roller 2 on the material cannot meet the standard, and the product is unqualified. Therefore, it is necessary to cool the first protection steps 21. On the other hand, the first protection steps 21 will adhere to dust particles such as cotton core particles on the production line during equipment operation. The thickness and distribution of the dust particles may gradually accumulate, so that the surface of the anvil roller 3 that should be in contact with the cutting edges is covered, and then the cutting edges cannot directly contact the anvil roller 3, or the cutting precision of the cutter roller 2 on the material cannot meet the standard.
