Crease-resistant film-pressing mechanism for PE heat-shrinkable film production

Abstract

The invention belongs to the technical field of heat-shrinkable film production auxiliary equipment, and particularly relates to a crease-resistant film-pressing mechanism for PE heat-shrinkable filmproduction. The crease-resistant film-pressing mechanism comprises a workbench and a lifting plate, wherein first fixing plates symmetric to each other are arranged at the two ends of the left side ofthe workbench; a prepressing roller is arranged between the two first fixing plates and rotatably connected to the inner walls of the first fixing plates; second fixing plates which are symmetric toeach other are arranged at the two ends of the right side of the workbench; and a winding drum is arranged between the two second fixing plates and rotatably connected to the inner walls of the secondfixing plates. According to the crease-resistant film-pressing mechanism, a heat-shrinkable film is stretched to be stressed, so that the heat-shrinkable film is more flat and prevented from wrinkling during winding; and meanwhile, the stretching distance of the heat-shrinkable film is adjusted by adjusting the vertical position of the lifting plate, so that the stress of the heat-shrinkable filmis reduced, the fracture deformation of the heat-shrinkable film caused by overlarge stress during winding is prevented, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of heat-shrinkable film production auxiliary equipment, and in particular relates to an anti-wrinkle lamination mechanism for PE heat-shrinkable film production. Background technique [0002] PE heat-shrinkable film is a surface protective film that can be used to wrap goods, which can reduce moisture damage to goods packaging caused by rain to a certain extent. It is fixedly bundled into a unit, so that the scattered small parts can be integrated into a whole. Even in an unfavorable environment, the product will not be loose or separated, and there will be no sharp edges and stickiness to avoid damage. [0003] The Chinese patent with the publication number CN209097832U proposes an anti-wrinkle lamination device for PE heat shrinkable film production. This patent can prevent the PE heat shrinkable film from wrinkling and improve the quality of the laminated film. On the bottom plate, the heat-shrinkable fi...

[0003] The Chinese patent with the publication number CN209097832U proposes an anti-wrinkle lamination device for PE heat shrinkable film production. This patent can prevent the PE heat shrinkable film from wrinkling and improve the quality of the laminated film. On the bottom plate, the heat-shrinkable film is pressed tightly on the bottom plate by the pressure roller. When the heat-shrinkable film is rewound by the winding drum, the heat-shrinkable film is easily broken or deformed, which is not conducive to the improvement of production efficiency.
