Embodiment Construction

[0012] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0013] Such as figure 1 An extruder screen changing device shown includes a screen changer body, a slide plate 1 installed between the two panels of the screen changer body, and a hydraulic device 2 installed on one side of the slide plate 1 to push the slide plate 1 to move. There are two adjacent identical longitudinal square grooves, and a porous plate 3 with a filter screen embedded in the front end is installed in the longitudinal square grooves.

[0014] Further, the upper end of the perforated plate 3 is provided with a step for positioning.

[0015] In order to reduce the flow fluctuation, it is necessary to minimize the solid plate area between the two porous plates. Because the perforated plate does not need to be taken out from the front of th...

Abstract

The invention relates to an extruder screen changer. The extruder screen changer comprises a screen changer body, a slide plate and a hydraulic device, wherein the slide plate is mounted between two panels of the screen changer body, the hydraulic is mounted on one side of the slide plate and pushes the slide plate to move, two close and identical longitudinal square grooves are formed in the slide plate, and a porous plate with a filter screen embedded into the front end face is mounted in each longitudinal square groove. The extruder screen changer has the advantages that the screens can be changed without shutdown, production stopping and raw material loss caused by screen changing can be avoided, cost is saved, and enterprise economic benefits are increased; material flow interruption is avoided, flow and pressure fluctuation are reduced, and product quality is increased; the whole extruder screen changer is compact in structure, simple to manufacture and use, convenient to maintain, stable in performance, safe and reliable, labor saving and simple through hydraulic control, and capable of lowering the labor intensity of workers.

Description

technical field [0001] The invention relates to a screen changing device for an extruder. Background technique [0002] In the production of plastic products, due to the fact that various raw materials will have a certain degree of impurities when they leave the factory, and as the price of raw materials rises, extrusion manufacturers have also increased the use of recycled materials in order to reduce costs, which makes plastics During extrusion production, molten raw materials will be mixed with some impurities, which will not only affect the quality of the product, but also hinder normal production. Therefore, in plastic extrusion production, in order to filter out impurities and obtain high-quality products, a filter device is essential. At the same time, the filter screen device can also increase the back pressure of the material flow to make the product compact and prevent the unplasticized material from entering the machine head. As the filter impurities increase, t...
