Description

Technical Field

[0001] The utility model relates to the technical field of pressure-sensitive adhesive production, and more specifically, to a filtering device for industrial production of pressure-sensitive adhesive. Background Art

[0002] Pressure-sensitive adhesive is a type of adhesive that can achieve bonding by applying pressure without the use of solvents or heat. It is widely used in bonding various materials, especially in situations where frequent disassembly or high-strength bonding is required.

[0003] In the prior art, glue will inevitably remain inside the filter container, which will not only cause a waste of glue raw materials, but also due to the sticky properties of the glue itself, the efficiency is extremely low during the screening and filtering process, and the user is often required to assist, which is time-consuming and labor-intensive, and increases the user's workload. At the same time, when feeding the glue, it is often necessary to select different containers as needed, but the existing filtering equipment often has only one feeding interface, which is very inconvenient to switch. At the same time, the filtering efficiency of the filtering equipment is different, and the feeding speed needs to be adjusted according to the filtering efficiency of the equipment. Too fast a feeding speed will cause glue accumulation, and too slow a feeding speed will affect the filtering efficiency. Utility Model Content

[0027] In this embodiment, when feeding, the glue is passed into the filter barrel 1 through the first feed pipe 7 and the second feed pipe 8, and the adjusting pipe 9 is rotated. The adjusting pipe 9 is rotated between the first feed pipe 7 and the second feed pipe 8, and then the position of the adjusting pipe 9 is moved. Through the cooperation of the sliding ring 15 and the sliding groove 16, the adjusting ring 11 drives the adjusting plate 12 to move, and the baffle 10 is supported by the adjusting plate 12, thereby adjusting the flow cross-sectional area of ​​the glue on the first feed pipe 7, and then adjusting the flow rate of the glue.

At the same time, the spiral blade 5 can clean and scrape the inner wall of the filter barrel 1. When the driving shaft 4 rotates, the stabilizing ring 14 rotates on the stabilizing block 13, thereby improving the stability of the rotation of the driving shaft 4. The driving shaft 4 drives the scraper 6 to rotate, and the bottom of the filter plate 2 is scraped and swept by the rotation of the scraper 6 to prevent the glue from adhering to the bottom of the filter plate 2 and affecting the filtering efficiency of the glue.

[0031] As needed, different material receiving devices or material receiving containers are connected to the first interface 20 or the second interface 21, and the conversion rod 22 is pulled outward.
