Device and method for spraying glue at crease position of folding film

Abstract

The invention discloses a device for spraying glue at the crease position of a folding film. The device for spraying glue at the crease position of the folding film comprises a folding film conveyingline, a nozzle and a right-angle moving shaft, and the folding film conveying line is located below the right-angle moving shaft; the right-angle moving shaft comprises an X moving shaft and a Y moving shaft, the X moving shaft is fixed, the X moving shaft comprises a rail I, and the Y moving shaft slides along the rail I; and the nozzle is located on the Y moving shaft, the Y moving shaft comprises a rail II, and the nozzle slides along the rail II. According to the device and the method for spraying glue at the crease position of the folding film, spraying the quick-drying glue at the folding position by adopting the nozzle, the glue spraying process is carried out in the conveying process of the folding film, so that the glue spraying transportation time is greatly shortened, so as to ensure that the width and the thickness of the fast-drying glue sprayed at the folding position are uniform and consistent.

Description

Technical field [0001] The invention relates to the field of filter element manufacturing. Specifically, it relates to a device and method for spraying glue at the crease position of a folded film. Background technique [0002] Industrial filter elements are widely used in the production process of chemical food and other production processes to purify industrial sewage, so as to achieve the purpose of classification and reuse of sewage. Since the production process of the filter element includes many links, especially when the quality of the industrial filter element needs to be higher, further requirements are put forward for each link in the production process. [0003] During the manufacturing process of the filter element, the reverse osmosis membrane needs to be folded in half, and then the coarse mesh is placed in the folding position to form a sandwich shape of the reverse osmosis membrane folded in half and the coarse mesh. Since the folding position is easily damaged du...

Problems solved by technology

[0004] In the prior art, a layer of adhesive tape is usually pasted on the folding position of the folding film by manual operation. This manual operation limits the realization of full automation, and the manual operation takes a long time and is inefficient. Due to the operator's proficiency There are slight differences in the position and direction of the tape, resulting in differences in the performance of the final filter element, which does not meet the existing industrial standards

On the other hand, the tape at the folded position is easy to fall off under water immersion, so that the folded position cannot be effectively protected, which affects the performance of the filter element
