Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tape production, in particular to a roller unit for producing reinforced flame-retardant adhesive tape. Background Art

[0002] In order to improve the flame retardant ability and strength of the tape, a reinforced tape can be designed. The reinforcements are mostly glass fiber mesh or glass fiber cloth layers with flame retardant additives added. The reinforcements are compounded in the tape layer. Due to the existence of the reinforcement layer, a certain support will be generated at the rib position during the tape compounding process, while there is no support in the gaps of the reinforcement layer. Therefore, after production is completed, a convex state in the shape of the reinforcement will be formed on the outer surface of the tape.

[0003] Most of the current pressure roller structures are hard roller bodies, or soft silicone sleeves are arranged on the rollers. However, their own deformation effect is not good, and they cannot effectively provide pressure to the upper and lower films in the gaps between the ribs. The pressure provided by the pressure roller is uneven, which affects the connection strength between the tape layers and the quality of the tape.

[0004] Therefore, designing a pressure roller unit that can evenly apply pressure to the reinforced tape is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The utility model aims to provide a pressing roller unit for producing reinforced flame-retardant tapes. By designing the roller surface of the pressing roller to be an airbag sleeve structure, the airbag sleeve at the composite point will be deformed through the support of the reinforced layer during the composite pressure application process, so that it can be embedded in the gap of the reinforced layer to apply pressure to the gap, ensuring uniform pressure during the composite process, greatly improving the connection strength between the layers of the tape, and improving the production quality of the tape.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
