Problems solved by technology

In the existing filter cartridge produced by this process, the adhesive between the strap and the filter material is not firm, and it is easy to fall off, which will easily cause the filter cartridge to deform and fail. Moreover, the glue is not environmentally friendly, and the filter material also needs to manually determine the folding distance. Not only increases the process cost, but also prone to uneven folding distance

Embodiment Construction

[0025] Embodiments of the present invention are described in detail below:

[0026] Such as figure 1 and figure 2 As shown, a filter cartridge fixed distance tooth mold 10 includes a body 110 and a tooth structure 120 arranged on the body 110. match the marks. The teeth of the tooth structure 120 cooperate with the creases of the filter material to fix the creases of the filter material and set the distance of the folds of the filter material.

[0027] The body 110 is further provided with a plurality of strip-shaped fixing grooves 130 , which are evenly distributed on the sides of the tooth-shaped structure 120 , and preferably, the plurality of strip-shaped fixing grooves 130 are arranged in parallel. During probation, change the fixed position of bar-shaped fixing groove 130, thereby change the fixed position of filter cartridge spacer tooth mold 10 on the fixed seat of filter cartridge distance device, make it can be compatible with the hot-melt generator of hot-melt d...

Abstract

The invention discloses a filter cartridge fixed-distance tooth mold, a filter cartridge distance-fixed device and a filter cartridge distance-fixed method. The filter cartridge fixed-distance tooth mold includes a body and a tooth-shaped structure arranged on the body. The tooth pitch of the tooth structure matches the creases on the filter material. The folding distance is fixed by the fixed-distance tooth mold of the filter cartridge, and the hot-melt technology is used to heat-melt the band on the filter material, and finally the two sides of the filter material are sealed by hot-melt technology to form a cylindrical filter cartridge. The method for fixing the distance of the filter cartridge can make the binding between the bandage and the filter material stick firmly, save the working procedure, and improve the work efficiency.

Description

technical field [0001] The invention relates to the field of filter cartridge production, in particular to a filter cartridge distance-fixing tooth mold, a filter cartridge distance-fixing device and a filter cartridge distance-fixing method. Background technique [0002] The currently produced slender filter cartridges need to be fixed in advance by bandages to keep the folding distance at a fixed width to prevent the filter cartridges from being deformed due to pulse blowback. The existing method is to sew one end of the strap on a fold with a needle car, and apply glue on the inner side of the strap, and then wrap the strap around a circular filter material with a fixed folding distance. After the glue solidifies, the filter paper The fixed folding distance is completed. In the existing filter cartridge produced by this process, the adhesive between the strap and the filter material is not firm, and it is easy to fall off, which will easily cause the filter cartridge to ...
