Mechanical flattening device for plastic

Abstract

The invention discloses a mechanical flattening device for plastic, and specifically relates to the technical field of plastic bag production devices. The mechanical flattening device for the plasticcomprises a device body, flattening side plates are fixedly installed on two sides of the interior of the device body, and a flattening mechanism is arranged between the two flattening side plates. The flattening mechanism comprises two side groove plates, one sides of the two side groove plates are fixedly installed on the side walls of the two flattening side plates respectively, a middle grooveplate is arranged in the middle between the two side groove plates, main shafts are arranged on the upper portion and the lower portion between the two side groove plates, two ends of the two main shafts are rotatably connected with the side walls of the two flattening side plates respectively, and the two ends and the middle portions of the two main shafts are rotatably connected with the upperportions and the lower portions of the two side groove plates and the middle groove plate respectively. According to the mechanical flattening device for the plastic, by making chains operate stably in side chain grooves and middle chain grooves, the chains will not swing, so the working positions of flattening rods are stable, and the flattening effect is uniform and reliable.

Description

technical field [0001] The invention relates to the technical field of plastic bag production equipment, more specifically, the invention relates to a plastic mechanical beating equipment. Background technique [0002] Plastic bag is a bag made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. It is an indispensable item in people's daily life and is often used to hold other items. The advantages of extremely light, large capacity, and easy storage are widely used. In the production process of plastic bags, the plastic bags need to be cut and separated, and the plastic bags need to be flattened before cutting, so that the cut plastic bags are relatively flat , without folding. [0003] In the chain tensioning process of existing equipment, there will be two situations: too tight and too loose. If the tension is too tight, it is easy to elongate the chain and reduce the service life of the chain. The wheel is tilted,...

[0003] In the chain tensioning process of existing equipment, there will be two situations: too tight and too loose. If the tension is too tight, it is easy to elongate the chain and reduce the service life of the chain. The wheel is tilted, the chain cannot run smoothly, and the sprocket and chain are easy to wear. If the tension is too loose, firstly, if the tension is too loose, the running process of the chain will be noisy, and secondly, the beating rod installed on the chain will be thrown back and forth. Phenomenon, unable to install the established trajectory operation, thus affecting the effect of beating

[0004] The distance between the existing punching rod and the hot needle is fixed, and the fixed distance leads to a fixed amount of punching that can be allowed. If the quantity is large, the space is too large when the quantity is small, which will affect the punching effect. If the quantity is small In the case of a large number, it cannot be done
