Abstract

The invention discloses a thermoplastic material filter screen baffle which comprises a filter main body; a plurality of filter holes which pass through front and back are formed in the filter main body, and one end, close to an outlet, of each filter hole is of a gradually enlarged structure, so that the tail end of a partition wall between the outlets of each two adjacent filter holes is of a sharp corner structure. According to the thermoplastic material filter screen baffle, the situation that part of filtered materials stay at dead corners of an outlet to cause overheating yellowing and coking of extruded materials and further generate new solid particles or impurities can be avoided, and the quality and the yield of injection-molded and extruded products are improved. In addition, the invention further discloses an extrusion device.

Description

technical field [0001] The invention relates to an extruding device, in particular to a thermoplastic material filter net baffle and the extruding device thereof. Background technique [0002] Existing plastic extruders generally need to filter before extruding molten plastic to remove impurities, sand or particles mixed in the molten plastic, so that the extruded plastic is pure and uniform in color, thereby improving product quality. quality. The existing filtering method usually adopts a filter screen, and a filter baffle 200 is arranged behind the filter screen. The filter baffle 200 is provided with a plurality of honeycomb-shaped through holes 201, and the molten plastic is filtered through the filter screen and then passed through the filter screen. These through holes 201 reach the extrusion nozzle. Although the filter screen can effectively remove various impurities, sand grains or particulate matter, there is a certain partition wall 202 between the through hole ...
