Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a filter for a production line extruder. Background Art

[0002] Extruder is a type of plastic machinery. According to the direction of the material flow in the die and the angle between the center line of the screw, the die head can be divided into right-angle die head and bevel die head. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material. Through steel mold molding, plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and the rare multi-screw extruders and screwless extruders.

[0003] The patent document with the prior art publication number CN216760771 U provides a filter for a production line extruder, comprising a feed die, a discharge die, and a filter disc rotatably mounted between the feed die and the discharge die, the feed die and the discharge die are provided with corresponding melt channels, a plurality of filter screen installation positions are evenly spaced on the circumference of the same radius of the filter disc, a filter screen is arranged on the filter screen installation position, the filter disc is driven by a driving device to rotate intermittently so that the filter screen installation position of the filter disc is aligned with the melt channel in turn, a plurality of seals are arranged on both sides of the filter disc, and the plurality of seals include sealing strips radially distributed between two adjacent filter screen installation positions, the sealing strip arranged on one side of the filter disc is tightly matched with the inner wall of the feed die, and the sealing strip on the other side is tightly matched with the inner wall of the discharge die to seal and isolate the filter screen installation positions of the filter disc. The utility model provides a filter for a production line extruder with better sealing to prevent melt flow.

[0004] However, during the use of existing extruder filters, when the filters have been used for a period of time, the filters need to be cleaned and replaced. However, when replacing and installing, most filters are installed and fixed by bolts and threads, which leads to cumbersome operation steps during installation and disassembly of the filters, making it inconvenient for workers to replace them. For this reason, we propose a filter for production line extruders. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies of the prior art, the utility model provides a filter for a production line extruder to solve the problems raised in the above background technology.

[0012] Preferably, the inner width of the mounting groove is matched with the outer width of the filter plate, and the mounting groove and the filter plate are both rectangular structures.

[0013] Preferably, two card blocks are provided, the two card blocks gradually become smaller from top to bottom, and the two card blocks are the same in size.

[0014] (III) Beneficial effects

[0015] The utility model provides a filter for a production line extruder, which has the following beneficial effects:

[0016] (1) The filter for the extruder of the production line has a telescopic groove, a clamping block and a telescopic spring. When the filter for the extruder is used, when the filter disc is clogged after a long period of filtration and needs to be cleaned and replaced, the staff starts the lifting rod, and the lifting rod drives the filter plate to move upward, and the filter plate moves out of the installation groove. Then the user presses the clamping block downward, and the clamping block squeezes the telescopic spring to shrink in the telescopic groove. At this time, the filter disc can be taken out from the through port, and at the same time, the telescopic spring pushes the clamping block to move out of the telescopic groove to reset it. After cleaning or replacing a new filter disc, the staff only needs to install the filter disc into the through port and push the filter disc backward. At this time, the sealing disc will squeeze the clamping block. Because the clamping block gradually becomes smaller from top to bottom, when the sealing disc squeezes the clamping block, the clamping block will move into the telescopic groove and squeeze the telescopic spring. When it is installed in place, the telescopic spring pushes the clamping block to reset and the filter disc can be installed and fixed. Therefore, the operation steps of installing and removing the filter are simplified, making it convenient for the staff to replace the filter. BRIEF DESCRIPTION OF THE DRAWINGS
