Film releasing system of press machine

Abstract

The invention discloses a film releasing system of a press machine. The film releasing system comprises a bottom plate; supporting columns are erected at two ends of the bottom plate; a lower film roll and an upper film roll are erected on the supporting columns; the middles of the two supporting columns extend in the same direction to form transverse supports; a rotatable lower film shaft is mounted between the two transverse supports through lower bearings; threads are arranged on the lower film shaft; two lower nuts are mounted on the lower film shaft and are clamped at two ends of the lower film roll to fix the lower film roll; the tops of the two supporting columns extend towards the transverse supports to form top supports; a rotatable upper film shaft is mounted between the two topsupports through upper bearings; threads are arranged on the upper film shaft; and two upper nuts are mounted on the upper film shaft and are clamped at two ends of the upper film roll to fix the upper film roll.

Description

technical field [0001] The present invention relates to a press, in particular to a film release device for a press. Background technique [0002] In the kitchen stove processing industry, the press is the necessary processing equipment for important parts such as the kitchen stove food bowl, which uses the designed mold to forge the required products. When forging and pressing the food bowl of the dining stove, because the upper and lower molds are all metal, in order to prevent scratches on the surface of the product, it is necessary to pad the upper and lower sides of the material with plastic film for cushioning. The process is continuous, which requires separate installation on both sides of the press. Film releasing device and film collecting device. [0003] The existing plastic film release device generally adopts the method of inserting the film release shaft into the center of the film roll, and then placing the film frame on the shaft frame. The disadvantage is t...

Problems solved by technology

[0003] The existing plastic film release device generally adopts the method of inserting the film release shaft into the center of the film roll, and then placing the film frame on the shaft frame. The disadvantage is that the film roll will easily drift and swing laterally on the film release shaft, and the film will Without effective deviation correction before entering the press, the film covering material is incomplete and leaky cover occurs, so that the upper and lower molds directly meet the material under great pressure, resulting in defective products, affecting product quality and reducing yield
