Film-rolling-roller film clamping device

Abstract

The invention discloses a film-rolling-roller film clamping device, relates to an improvement to a film clamping device on a film rolling roller when a film on the film processing tail section of PVC production line equipment is rolled, and provides a film rolling device which can be used for effectively rolling a film at the initial rolling stage of the film. According to the technical scheme, the film-rolling-roller film clamping device is arranged on the surface of a film rolling roller and comprises the film rolling roller and a film rolling cylinder, the film rolling cylinder is connected to the film rolling roller in a sleeved mode and is in close fit with the film rolling roller, the film rolling cylinder is provided with a notch, and the film clamping device further comprises a bar groove, a film clamping bar, a film groove, spring buckles and buckle grooves; the buckle grooves are formed in the walls of the bar groove, at least two buckle grooves are formed in the walls on two sides of the bar groove, and the buckle grooves on the two sides correspond to one another one to one; the spring buckles are arranged inside the buckle grooves and matched with the buckle grooves; the film clamping bar is a strip-shaped bar, the upper portion of the section of the strip-shaped bar is short, the lower portion of the section of the strip-shape bar is long, and the film clamping bar is arranged inside the bar groove; the film groove is formed in the upper surface of the film clamping bar. According to the film-rolling-roller film clamping device, machining processes of the buckle grooves are simplified, and the film clamping bar can be taken out conveniently.

Description

technical field [0001] The invention relates to a film blocking device for a roll film roll, in particular to the improvement of the film block device on a film roll roll when the film is rolled up at the end of film processing on PVC production line equipment. Background technique [0002] When processing PVC boards, it is necessary to stick a protective film or protective paper on both sides of the PVC board. The film or paper enters the pasting equipment together with the PVC board through the film conveying roller. In the production process, it is often necessary to take up the film through the film roll. Since the film is thin, the friction between the film roll and the film roll is small. In the early stage of film roll, the film is not easy to roll up, which greatly reduces the production efficiency. Contents of the invention [0003] In view of the above problems, the present invention proposes a film rolling device that can effectively roll up the film at the ini...
