Description

Technical Field

[0001] The utility model relates to the technical field of glue filter, in particular to an anti-extrusion inner support filter. Background Art

[0002] Glue is a viscous liquid substance, which is usually formed by dissolving or dispersing a high molecular polymer or other viscous components in a certain solvent. Glue has good bonding properties and can firmly bond different materials together.

[0003] In order to improve the quality of the glue liquid, during the production and processing of the glue liquid, it is necessary to filter out impurities, particulate matter, etc. in the glue liquid through a filter, which can make the final product purer and more uniform, and avoid product performance degradation or defects due to the presence of impurities.

[0004] However, in order to facilitate the filtering and collection of impurities, existing glue filters are usually set to filter from the inside to the outside. This filtering method can filter impurities through the filter mesh on the surface of the filter when facing conventional glue, and can collect impurities inside the filter, and can regularly clean the impurities. However, when filtering glue with high viscosity, the method of discharging glue from the inside to the outside will produce a large squeezing effect on the filter mesh on the surface of the filter. Due to the excessive pressure of discharging glue, the filter mesh will expand and deform, lose the filtering effect, and thus shorten the service life of the filter when dealing with such glue with high viscosity. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-extrusion internal support filter, including an installation shell, an installation groove is opened inside the installation shell, a glue outlet bin is connected to the installation groove, an installation sleeve is detachably connected in the installation groove, a filter screen is arranged on the installation sleeve, an internal support column for supporting the filter screen is arranged inside the installation sleeve, and a plurality of glue passing grooves for glue to pass through are opened around the outer wall of the inner support column.

[0006] Through the above technical solution, the glue liquid can be filtered from the outside to the inside. When the glue liquid with higher viscosity needs to be filtered, the glue liquid will produce an extrusion effect on the filter from the outside to the inside. At this time, since the inner support column for supporting the filter is arranged inside the installation sleeve, the filter net can be effectively supported to prevent the filter net from being deformed by strong squeezing, so as to extend the service life of the filter.

[0007] Furthermore, a glue inlet and a glue outlet are connected and arranged on the mounting shell, and the glue outlet is connected to the glue outlet bin.

[0008] Through the above technical solution, the glue liquid enters the installation groove from the glue inlet, is filtered by the filter screen, and then flows into the glue outlet bin. The filtered glue liquid is finally discharged through the glue outlet.

[0009] Furthermore, a fixing seat is arranged at one end of the installation sleeve, and a docking limit hole is arranged at one end of the installation sleeve away from the fixing seat.

[0010] Through the above technical solution, the docking limit hole is used to help limit and support the installation sleeve.

[0011] Furthermore, the mounting sleeve, the inner support column and the fixing seat are connected in sequence by docking bolts, and the ends of the docking bolts are threadedly connected to the fixing seat.

[0012] Through the above technical solution, after the initial assembly of the filter or the subsequent cleaning and maintenance of the filter, the inner support column can be first placed in the installation sleeve, and then the installation sleeve and the fixing seat can be combined, and finally the three can be connected and locked by the docking bolts to complete the assembly.

[0013] Furthermore, a limited docking column is provided on one side of the installation groove away from the fixing seat, and the installation sleeve cooperates with the limited docking column structure through the docking limited hole.

[0014] Through the above technical solution, when installing the installation sleeve, the docking limit hole and the limit docking column can be aligned and installed first, so as to complete the limitation and support of the installation sleeve.

[0015] Furthermore, a sealing ring is arranged on the outer wall of the mounting sleeve.

[0016] Furthermore, a threaded section is provided on the fixing seat, and the fixing seat is threadedly connected to the inner wall of the installation groove through the threaded section.

[0017] Through the above technical solution, by threading the fixing seat and the mounting groove, after the fixing seat is installed and fixed, the sealing ring can fit tightly against the inner wall of the mounting groove, which can effectively prevent the glue from seeping out from the outer surface of the mounting sleeve, ensuring that the glue can pass through the filter net smoothly and fully filter the glue.

[0018] Furthermore, a sealing gasket is provided on the side of the fixing seat that contacts the inner wall of the mounting groove.

[0019] Through the above technical solution, by threading the fixing seat and the mounting groove, after the fixing seat is installed and fixed, the gap between the fixing seat and the mounting groove can be sealed by a sealing gasket to prevent glue from leaking out of the fixing seat.

[0020] Furthermore, a plurality of glue through holes are formed around one side of the fixing seat close to the filter screen.

[0021] Through the above technical solution, after the glue liquid is filtered by the filter screen, it will be discharged into the glue outlet bin through the multiple glue liquid through holes.

[0022] Furthermore, the inner diameter of the installation groove is larger than the outer diameter of the filter screen, and the sealing ring matches the inner wall structure of the installation groove.

[0023] Through such an arrangement, the glue liquid can fully contact the surface of the filter mesh, and the filtering effect of the filter mesh can be fully utilized.

[0024] Compared with the prior art, the utility model provides an anti-extrusion internal support filter, which has the following beneficial effects:

[0025] In the utility model, the glue liquid can be filtered from the outside to the inside. When the glue liquid with a higher viscosity needs to be filtered, the glue liquid will produce an extrusion effect on the filter screen from the outside to the inside. At this time, since the inner support column for supporting the filter screen is arranged inside the installation sleeve, the filter screen can be effectively supported to prevent the filter screen from being deformed by strong extrusion, so as to extend the service life of the filter.
