The main structure includes a glue tank and an injection molding part. The top of the glue tank is welded to the fixed end of the injection molding part. The filtration disassembly structure includes a filter and a disassembly part. The two ends of the filter are respectively welded to the inner wall of the disassembly part, and the top of the disassembly part is coupled to the bottom of the glue tank. Although this technical solution adopts a multi-stage filtration structure to improve the problem of impurities easily clogging the filter holes to a certain extent, the flange structure needs to be connected with multiple sets of screws, and the problem that the filter components are not easy to disassemble has not been solved; and the filtration mechanism needs to be directly replaced, and the collected undissolved particles, agglomerated materials, etc. cannot be recycled, resulting in waste of resources and high cost of use.

When the glue passes through the filter device 3, the insoluble impurities and agglomerated materials are intercepted and collected by the cut-off barrel 10, and then the fine particles are further filtered by the fine filter cartridge 8, and then enter the glue discharge section 2 and pass through the glue outlet 5 for discharge; after a period of use, the discharge section is unscrewed by the threaded connection structure, and then the filter device 3 on the partition 6 can be cleaned or replaced. The utility model effectively removes impurities in the glue through multiple filtering and interception mechanisms, improves the purity and use effect of the glue; its structural design is reasonable and compact, easy to install and maintain, and the cut-off barrel 10 intercepts and collects impurities to avoid clogging the fine filter cartridge 8, thereby extending the service life of the device, and is also conducive to the recovery of undissolved particles and agglomerated materials in the glue.

The vertex of the diverter cone 14 is located on the central axis of the glue feeding section 1. When the glue enters the glue feeding section 1 from the glue inlet 4, the diverter cone 14 can guide the glue to flow along its surface, so that it flows to the filter device 3 more concentratedly and evenly. This helps to avoid the glue from generating eddy currents or dead corners inside the glue feeding section 1, thereby improving the filtering efficiency.

[0023] Furthermore, the cutting barrel 10 is made of an integrally formed soft silicone material, which makes it convenient to remove the cutting barrel 10 and turn it inside out for cleaning.

Preferably, the mesh density of the glue outlet filter 18 is greater than the fine filter 13, which can further filter impurities in the glue to ensure the purity of the output glue.

[0026] Furthermore, the connection between the outer liner 9, the fine filter cartridge 8 and the partition 6, and the connection between the partition 6 and the glue inlet section 1 are all sealed. Specifically, each threaded connection can be provided with a sealing ring / gasket to form a sealing structure to prevent glue leakage or contact with air to cause glue solidification.
