Description

Technical Field

[0001] The utility model relates to the technical field of production molds, in particular to a roller-type sheet plastic product production mold. Background Art

[0002] Roller-type sheet plastic product production molds are usually used to produce plastic films, plastic sheets and other products. Common applications include plastic bags, packaging films, ground films, etc. This type of mold is usually composed of multiple rollers, and the plastic raw materials are squeezed, stretched, cooled and formed through the pressure and tension between the rollers.

[0003] In the prior art, most roller-type sheet plastic product production molds are not convenient for adjusting the spacing between the active roller and the driven roller during use, resulting in the production line lacking flexibility to adapt to products of different thicknesses. The mold must be replaced to produce plastic products of different thicknesses, increasing production line adjustment and downtime.

When the mold is in use, the threaded rod is driven to rotate by the first servo motor 4, so that the height of the driven roller 10 can be raised and lowered, thereby adjusting the gap between the driven roller 10 and the driving roller 22 to adapt to the thickness of the sheet plastic product to be produced, which not only improves the practicability and adaptability of the production line, but also does not need to replace the entire mold, thereby improving the efficiency of production adjustment, and at the same time helps to ensure the uniformity and stability of plastic extrusion, and is conducive to controlling the consistency of product thickness, thereby improving product quality.

[0035] Both sides of the inner upper end of the bracket 2 are fixedly connected with sliding rods 20, and the upper ends of one side end surfaces of multiple limit plates 18 are fixedly connected with sliding rings 19. Multiple sliding rings 19 are slidably connected to the sliding rods 20.
