Problems solved by technology

[0003] The existing filter screen replacement structure is mainly manual replacement, and has the following defects: 1. The filtering performance of the filter screen is limited, and it is impossible to filter impurities with different radii, and the filter screen cannot be replaced automatically, and the automation level is low; 2. .When there is blockage between the filter screens, it cannot be quickly dredged, and the maintenance time is likely to delay production; 3. Due to the blockage, the replaced filter screen needs to be cleaned manually, which requires human resources. Therefore, a plastic blow molding automatic screen change structure is developed It is a technical problem to be solved by those skilled in the art

Abstract

The invention discloses a working method of an automatic net changing structure for plastic blow molding, and relates to the technical field of plastic blow molding machines. A blow molding machine towhich the working method relates comprises a conveying device and a net changing box, wherein an electric control box is fixedly connected to one side wall of the conveying device; a cleaning box isfixedly connected to the top of the net changing box; two butt joint devices are fixedly connected to the two sides of the net changing box; two driving devices are arranged in the interior of the netchanging box; the inner bottom surface and inner top surface of the net changing box are both fixedly connected with lifting devices; and three filtering devices are movably connected between the twodriving devices. According to the working method, the driving devices and the conveying device are matched with one another, so that the automatic replacement of the filtering devices is realized, and the replaced filtering devices are sprayed and cleaned in the interior of the cleaning box to facilitate the recycling; the lifting devices can change the overlapping area of filtering holes and thereby changing the sizes of the filtering holes, so that impurities with different sizes and diameters are filtered away; and the impurities can also be sheared through the relative sliding of the filtering holes, and the rapid dredging can be realized.

Description

technical field [0001] The invention relates to the technical field of plastic blow molding machines, in particular to a working method of an automatic screen changing structure for plastic blow molding. Background technique [0002] A blow molding machine is a plastic processing machine. After the liquid plastic is sprayed out, the plastic body is blown and attached to a mold cavity of a certain shape by using the wind force blown out by the machine to make a product. This kind of machine is called a blow molding machine; during the production process of a blow molding machine, plastic After the melt is plasticized and heated for a long time, there will be decomposition residues in the melt, plus other impurities in the raw materials. Once they enter the machine head, they will cause blockage of the flow channel. In order to avoid the problem of blockage, usually A filter screen will be set between the barrel and the machine head. [0003] The existing filter screen repla...
