[0002] In the manufacturing process of plastic handles, they are manufactured through processes such as stirring, heating and melting, and extrusion molding of synthetic resin and various additives. There are many types of additives for plastic raw materials, including fillers, plasticizers, stabilizers, lubricants, colorants, etc. Therefore, a plastic mixer is required to mix the raw materials evenly before heating and melting to ensure the quality of plastic products. After the plastic handle is formed, a clamping device is needed to clamp the handle to facilitate manual operation links such as trimming and labeling.
[0003] Currently, the Chinese utility model with the publication number: CN215510701U discloses a clamping device for processing, including a base mechanism. Two support mechanisms are fixedly connected to the upper end of the base mechanism. Two adjusting mechanisms are threadedly connected to the upper ends of the two support mechanisms. One end of the two adjusting mechanisms is fixedly connected to two clamping mechanisms. This device fixes the base, and then according to the height of the wood, pulls out the block and slides the connecting rod in the inner groove, and drives the clamping block to rise. Then, one end of the block penetrates through the first card slot and extends to the inner side of the inner groove to be clamped with the second card slot, fixing the raised clamping block. Then, rotate the rotating rod to drive the threaded rod to rotate and drive the rotating disc to rotate in the circular groove. The rotation of the rotating disc in the circular groove drives the clamping block to approach the wood and fixes both sides of the wood, effectively realizing that the existing clamping device for wood processing can adjust the height of the clamping block according to the height of the wood, making it more convenient and firm to clamp woods of different heights.
[0004] During the adjustment of this clamping device, the two clamping mechanisms need to be adjusted separately. When it is necessary to cooperate with external equipment for use, it is not convenient to keep the workpiece centered. At the same time, the adjustment is cumbersome. And during the longitudinal adjustment of the connecting rod, it is often necessary to adjust according to the height of the workpiece first.
