Description

Technical Field

[0001] This utility model relates to the field of adhesive tape production technology, and in particular to a dust-free device for adhesive tape production. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It connects two or more unconnected objects together by bonding. Its surface is coated with an adhesive, and modern adhesives widely use various polymers. Common sealing and packaging tape (BOPP biaxially oriented polypropylene) is an indispensable daily necessity for any business, company, or individual.

[0003] A search revealed a patent with publication number CN214399169U entitled "A Dust-Free Roll Material Device for Adhesive Tape Production." The technical problem it addresses is the dust pollution that easily occurs during adhesive tape production due to substandard environmental hygiene. The device utilizes a dust-collecting blower, dust outlet, positive pressure dust exhaust pipe, airflow rotating cover, cover shaft, flip-top sealing cover, and dustproof breathable plate. First, the flip-top sealing cover is lifted, then the adhesive tape passes through a transmission roller and connects to a roll material roller motor. The roll material roller motor collects the adhesive tape. Afterward, the flip-top sealing cover is closed for sealing. At this point, the dust-collecting blower... The filter inlet draws in clean, dust-free air, which is then discharged through the dust outlet and positive pressure dust exhaust pipe. The air discharged through the positive pressure dust exhaust pipe increases the air pressure inside the airflow rotating cover, creating a high-pressure space. The airflow in this high-pressure space flows from inside the airflow rotating cover to the outside, preventing external dust from flowing into the cover. The dust outlet blows away dust from outside the device, and the airflow direction can be adjusted by rotating the air outlet blades. However, the following drawbacks still need to be addressed: the cleanliness of both sides of the substrate affects the adhesion of the adhesive and the initial and holding strength of the material. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust-free device for adhesive tape production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
