Abstract
Description
Technical Field
[0001] This utility model relates to the field of tape production technology, specifically a feeding device for the production of waterproof butyl tape. Background Technology
[0002] Waterproof butyl tape is a high-performance waterproof sealing material made with butyl rubber as the core raw material. With its excellent sealing performance, weather resistance and ease of construction, it has become the mainstream waterproofing choice in the fields of construction, industry, and automobiles.
[0003] The adhesive layer of waterproof butyl tape is mainly composed of butyl rubber, and various auxiliary materials such as polyisobutylene and calcium carbonate need to be added during the internal mixing process. Chinese Patent Publication No. CN 217625802U discloses a feeding device for the production of waterproof butyl tape, including a mounting base. Two fixed columns are connected to the upper surface of the mounting base. The fixed columns have mounting grooves. Telescopic columns are sleeved in the mounting grooves. One end of the telescopic column is fixedly connected to a mounting frame. One end of the mounting frame is rotatably connected to a connecting block. The other end of the connecting block is fixedly connected to a fixed frame. A feeding cylinder is sleeved on the fixed frame. One end of the feeding cylinder is fixedly connected to an extruder. The other end of the extruder is fixedly connected to a first motor. The end of the feeding cylinder near the first motor is fixedly connected to a feed hopper. The diameter of the drive rod decreases from left to right.
[0004] The aforementioned feeding device uses a drive rod to drive the feeding blades to achieve the feeding effect; however, most of the additives added during the internal mixing of butyl rubber tape are in solid form, and the volume of solid additives varies greatly. This means that the larger additives take a relatively long time to fully mix with the butyl rubber, reducing the efficiency of the internal mixing process. The aforementioned feeding device cannot change the volume of the additives, thus failing to improve the efficiency of the internal mixing process. Utility Model Content
