Screen changer is widely used in polyester and spinning production line. Its main purpose is to remove solid impurities such as organic melt, carbonized particles and metal oxides in melt, improve product quality, provide qualified raw materials for downstream process and ensure normal production of downstream process. Therefore, the factors affecting the service life of the screen chqnger filter element are analyzed and the device is technically reformed, which prolongs the service life of the

The special non-stop screen changer for casting, sheet and sheet material adopts multi-network reciprocating filtering technology, single channel or multi-channel screen changer filtering at the same time, with self-contained voltage stabilization and mobile automatic exhaust mechanism, which has better sealing and wear resistance than the ordinary fast screen changer. When changing the screen, it does not stop the machine, keep feeding and affect normal production. Common fast switching device

The screen changer (filter) is an automatic switching device consisting of one or more filters, which is used to filter out the particles and impurities contained in the plasticized material flow filter. The filter screen is supported by an alloy porous plate or wire mesh. The porous plate or wire mesh is installed on the carrier of the filter. The carrier is driven by hydraulic cylinder to switch between the working position of a system and the off-line non-working position. The filter screen o

Application area of screen changer It is used for melt filter screen changer in plastics, rubber, chemical fiber and ceramics extrusion production line. These switchers - from low-cost manual switchers to highly complex non-stop voltage regulated automatic switchers, are suitable for extruders with screw diameters of 35 mm to 300 mm. The net changer is often used in the following production lines: 1. from plastic resin synthesis reaction device to bulk granular extrusion granulating production l

Structure of screen changer In order to ensure the filtering effect, the screen changer is generally composed of three parts: support plate (shunt plate), auxiliary plate and filter screen, and the filter screen is generally made of metal woven mesh. But sometimes for special needs, silk screen and sand filtration are used as polyester. Nylon is coated with sand to remove gel and impurities. In order to increase filtering face and improve filtering capacity, plug-in filters have been developed b

Single plate and double plate, single and double column hydraulic screen changer , quick screen changing, easy operation and maintenance. With built-in sealing device, the sealing performance is good, which can meet the production of arbitrary polymer high extrusion capacity, and can be used with different standard extruders. The time for fast changing the network is less than 2 seconds, and the filter area is selected between 30mm- and 250mm. High abrasion resistance, high pressure resistance a

1. In order to maximize production capacity, reduce costs, improve efficiency, increase benefits and maximize profits, it is necessary to adopt non-stop network screen changer in the use of recycled materials and corner materials. 2. The use of mesh screen changer in the production of new materials can increase the plasticity and homogeneity of melt, and it is also a necessary guarantee for the quality of products. Although there are almost no impurities in the new materials, in the actual produ

Any kind of plastic products we have a suitable for its mesh screen changer , each plastic production process and raw materials are different, the requirements for the mesh screen changer are also different. Therefore, we have carried out one-to-one targeted research and design, developed a variety of special netting device, such as: XPS Extrusion board special non-stop netting device; blowing film special non-stop netting device; pipe industry special non-stop netting device; wire drawing machi

Melt belt filter automatic mesh screen changer (mesh belt type mesh screen changer) is a true sense of automatic mesh screen changer, the use of melt pressure or time control mesh screen changer action. The distance and speed of the filter can be set freely. When the pressure or time reaches a set value, the filter automatically moves evenly, and the impurities are brought out of the screen changer with the filter. After setting up, the mesh changer can run completely automatically without manua

At present, the mesh screen changer can be divided into manual mesh screen changer , electric mesh changer, pneumatic mesh changer, hydraulic mesh changer and so on according to the power of mesh changer, among which hydraulic mesh changer is the most widely used. For manual mesh screen changer, electric mesh changer, pneumatic mesh screen changer ; according to the power of the mesh changer, the meaning is to use manual mesh changer, motor-driven mesh changer, pneumatic mesh changer, because th
