Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cigarette production, and particularly relates to a copper chain automatic cleaning device and cleaning method for a cutting machine. BACKGROUND

[0002] The copper chain of the cutting machine in the tobacco industry is a key component for material conveying. During production, the material is sent to the lower copper chain by the feeding trolley, the upper copper chain is inclined to form an angle with the lower copper chain, and the material is compressed and conveyed to the knife door by the lower copper chain during the reverse movement of the two, and is cut into tobacco by the rotating knife roller.

[0003] However, there are problems in the conveying process: the channel between the upper and lower copper chains is gradually narrowing, the tobacco is squeezed and rubbed, and the broken tobacco is easily adhered to the grooves of the copper chain. If not cleaned thoroughly during maintenance, the tobacco foam will repeatedly accumulate and harden, and the amount will gradually increase. This will fill the grooves, reduce the friction between the tobacco and the copper chain, cause the material to slip and deviate, affect the stability of the conveying, and even cause uneven cutting, equipment jamming, affect the production efficiency and quality.

[0004] In addition, the current maintenance method of the copper chain has limitations. Most workshops still rely on manual cleaning with a brush, which requires the equipment to be stopped for operation. Because the copper chain is several meters long and the grooves are fine and dense, it needs to be repeatedly wiped to clean the hardened tobacco foam, which not only consumes manpower, but also has low cleaning efficiency for a single device. The effect of manual cleaning is affected by the operation standard, and if not cleaned thoroughly, the residual tobacco foam will accelerate the subsequent accumulation, forming a vicious cycle.

[0050] The opening 43 is long strip-shaped, the long side of the opening 43 is parallel to the connecting rod 3, and the brush plate fixing rod 7 reciprocatingly moves along the long side of the opening 43 in the opening 43.

[0051] The main plate front face 411 of the support plate 4 is provided with compressed air blowing nozzles 5, the compressed air blowing nozzles 5 are directed to the brush plate 8 on the main plate front face 411, and thus the tobacco tar cleaned by the brush is blown away.

[0052] The compressed air blowing nozzles 5 are two, and are located on both sides of the brush plate 8 respectively.

[0053] The positioning magnets 6 are installed on the side plates 42 of the support plate 4, and thus the copper chain cleaning device is fixed on the tobacco cutter wall plates on both sides of the tail end of the copper chain.

[0061] S3, by the elastic force of the brush spring installed at one end of the brush plate fixed rod, the brush plate at the end of the brush spring is tightly attached to the surface of the copper chain of the cutting machine. With the reciprocating linear motion of the brush plate fixed rod, the brush plate reciprocatingly cleans the surface of the copper chain.
