Description

Adhesive tape length meter number rolling compression roller device

Technical Field

The utility model relates to an adhesive tape compression roller technical field specifically is an adhesive tape length meter number rolling compression roller device.

Background

The rolling compression roller belongs to a unit component of a rolling mechanism of a coating machine, under the pushing action of a cylinder or a spring, the back of the adhesive tape is uniformly stressed, so that the adhesive tape is uniformly and tidily wound on the surface of a hollow reel, a traditional rolling compression roller mechanism is sleeved with an elastic rubber layer on a steel roller core, and the adhesive tape made of different film materials is matched by generally adopting the material and the shore hardness of the elastic rubber layer. The disadvantage is that the rubber having a lower hardness has a greater friction force against the film surface of the adhesive tape. When the adhesive tape is tightly pressed and rolled, the adhesive tape needs to be tightly attached to the surface of the reel, and poor appearance of the adhesive surface due to the fact that air in the reel is close to the reel can be avoided. No matter the rubber is silicon rubber, PU rubber or nitrile rubber, the softer the material is, the stronger the adhesive force between the press roller and the film surface of the adhesive tape is, and the more the film material and the rubber roller can not slide. When a tape film roll is wound up in a length of 1000m or more, wrinkles occur due to flatness deviation of the roll due to accumulated tolerance.
