Four-roller plastic calender with wider application range

Abstract

The invention relates to the field of plastic processing, and discloses a four-roller plastic calender with a wider application range. The four-roller plastic calender comprises a calender shell, wherein a first sliding rod is arranged inside the calender shell, and the surface of the first sliding rod is slidably connected with sliding blocks; the surfaces of the sliding blocks are sleeved with moving plates, rotating discs are rotationally connected to the ends, away from the first sliding rod, of the sliding blocks, and rolling rollers are rotationally connected to the other ends of the rotating discs; and a rotating handle is connected to the right side of the calender shell in an inserted mode, a gear is fixedly connected to the surface of the left end of the rotating handle, and a bearing is fixedly connected to the surface of the rotating handle; and second connecting rods are fixedly connected to one sides of the sliding blocks. The moving plates, the gear, the rotating handle,the bearing and the sliding blocks are arranged to form the device capable of being lifted manually, and synchronous lifting of the rolling rollers can be guaranteed, so that deviation, caused by lifting, of calendered plastic is avoided, and the practicability and functionality of the device are improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a four-roller plastic calender with wider application range. Background technique [0002] Plastic processing is a general term for various processes that convert synthetic resin or plastic into plastic products, and the equipment used for plastic processing includes injection molding machines, extrusion machines, calenders, etc. Calenders are key equipment in the process of plastic calendering, basically There are four rolls or five rolls, at least three rolls, but there are some problems when the number of rolls is large, such as the distance between the rolls is not easy to adjust, so that a calender can only roll the same thickness. Plastics have limitations. For example, when you need to calender a thicker plastic, you need a calender with a larger roller pitch. This will not only better adapt to the thickness of the plastic, but also increase the lateral distance...

Plastics have limitations. For example, when you need to calender a thicker plastic, you need a calender with a larger roller pitch. This will not only better adapt to the thickness of the plastic, but also increase the lateral distance. Better fix the calendered plastic to ensure the effect of plastic calendering
