Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape production equipment, in particular to anti-static equipment used in adhesive tape production. Background Art

[0002] In the production process of adhesive tape, rollers are basically used to convey and guide the tape. There are many rollers in the production equipment, and basically all rollers are in direct contact with the tape and have relative motion. After long-term friction with the rollers, the tape is easily charged with static electricity, which causes the finished tape to be adsorbed and stuck together after it is rolled up, making it difficult to separate. Therefore, the tape needs to be destaticized.

[0003] For example, Chinese patent CN217486683U proposes an anti-static device for rubber conveyor belts, including a fixed ground-connected frame, and adjustable support seats are symmetrically fixedly installed on the ground-connected frames at both ends of the laminating roller, and the two adjustable support seats are used to realize the rotational support of the central axis at both ends of the laminating roller, and the end of one of the adjustable support seats is used to connect to an external power device, and a lateral static removal component is installed on the ground-connected frame upstream of each adjustable support seat, and the two lateral static removal components are arranged oppositely and cooperate to realize the removal of excess static charge on the surfaces of both sides of the cover rubber and the tape. In this way, the static electricity on the surface of the cover rubber and the tape can be removed during the laminating process of the laminating roller on the cover rubber and the tape.

[0004] However, the above patent requires the use of an electrostatic generator to remove static electricity, which is costly and requires the discharge needle to be replaced regularly, and the replacement steps are relatively complicated.

[0005] Based on this, the utility model designs a destaticizing device for adhesive tape production to solve the above problem. Utility Model Content
