Description

A PE film winding mechanism with static elimination structure

Technical field

The utility model relates to the technical field of PE film production equipment, specifically to a PE film winding mechanism with a static elimination structure.

Background technique

In the process of PE film production, the processed PE film needs to be rolled up. During the rapid rewinding and unwinding process, a large amount of friction, peeling, and extrusion will occur between the material and the roller, causing different electrical properties to accumulate on the surface of the object. The static charge accumulates with the increase of speed and time, causing serious static electricity problems. Generally, a static eliminator is installed at a certain distance from the product at the angle of the rewinding and unwinding. However, the existing rewinding mechanism itself It does not come with a static eliminator, and when installing a static eliminator, the heights of the winding mechanisms and corresponding pressure rollers and other equipment in different production workshops are different, resulting in different angles for the rewinding and unwinding, which poses problems for the installation of the static eliminator. Come difficult.

The utility model patent with the authorization announcement number CN216072312U discloses a winding mechanism for producing PE film, which includes a bottom plate. Two first brackets are installed on the upper front of the bottom plate. Mounting seats are installed on the lower ends of the first brackets. The mounting base is fixedly connected to the bottom plate. A mounting frame is installed in the middle of the right side of the first bracket on the left side. A sensor is installed inside the mounting frame. A flip cover is installed on the upper end of the first bracket, and a first hinge is installed on the rear end of the flip cover.

Although this technical solution has an installation frame installed inside the first bracket on the left, a sensor is installed in the middle of the right side of the installation frame, and the sensor is electrically connected to the driving motor. When the winding drum is rolled up to a certain amount, it will be detected by the sensor. , when the sensor detects the PE film outside the rewinding drum, it can automatically shut down the electric drive machine and stop the rewinding drum for rewinding, so that the length of the rewinding PE film is equal, reducing errors, and making the PE film suitable for batch production. Production, improve the practicality and accuracy of the rewinding mechanism, but the equipment is not equipped with a static eliminator, and there is no way to solve the static problem caused by friction, peeling, and extrusion of the PE film during the rapid rewinding and unwinding process. In view of this, we propose a PE film winding mechanism with a static elimination structure.
