Plate extrusion addition type width adjustment apparatus

Abstract

The invention relates to a plate extrusion addition type width adjustment apparatus. According to the apparatus, a fixation part is arranged on an extrusion mold; one end of a moveable rocker arm is fixed on the fixation part respectively through a support part and puller bolts, and the other end of the moveable rocker arm is connected with a pressing tongue seat; a pressing tongue is inserted in the pressing tongue seat; and the pressing tongue is embedded in a mold outlet. The apparatus of the present invention has characteristics of reasonable structure, easy maintenance, adjustable width, accurate size, no pollution, low cost, high efficiency, controllable online tracking, safety, reliability, and the like. According to the present invention, an arc pressing tongue technology is adopted, such that a function of width adjustment can be achieved without replacement of the mold in production lines of sheet products and plate products, yields of plates and sheets are increased, a function of adjustments of widths of plates and sheets produced by the same mold in a plurality of specifications is achieved, mold utilization rate and production efficiency are improved, one-time forming rate is high, energy sources and raw materials are saved, production cost is reduced, and the apparatus is an ideal special apparatus for online adjustment of widths of various sheets and plates, and the like.

Description

technical field [0001] The invention relates to auxiliary equipment for plastic processing, and more specifically relates to an external width adjusting device for extruded boards with adjustable widths for production equipment such as various sheets and boards. Background technique [0002] At present, in the production of plastic sheets and sheets, the traditional sheet width is determined by the width of the extrusion opening of the mold, and the exit width of the mold is the width of the sheet or sheet, which cannot be adjusted arbitrarily. If plates or sheets of different specifications are produced, it is necessary to replace the mold or cut it into the required size, and the replacement of the mold will increase the amount of molds, resulting in an increase in production costs; usually the production of sheets and plates cannot control the width and only the excess width can be cut by cutting. The material is cut, crushed, and reused. Therefore, there are many leftove...

AI Technical Summary

Problems solved by technology

[0002] At present, when producing plastic sheets and sheets, the traditional sheet width is determined by the width of the extrusion opening of the mold, and the exit width of the mold is the width of the sheet or sheet, which cannot be adjusted at will.

If plates or sheets of different specifications are produced, it is necessary to replace the mold or cut it into the required size, and the replacement of the mold will increase the amount of molds, resulting in an increase in production costs; usually the production of sheets and plates cannot control the width and only the excess width can be cut by cutting. The material is cut, crushed, and reused. Therefore, there are many leftovers after cutting, which is crushed and reused, which takes a lot of labor and materials, pollutes the environment, increases energy consumption, and increases production costs.

Therefore, it cannot meet the needs of the current processing and production of dynamic products such as plates and sheets.
