Novel film expanding platform

Abstract

The invention relates to a novel film expanding platform, comprising a film cutting mechanism, a film adsorbing frame, a bracket, springs and a thin film supporting roller, wherein the film adsorbing frame is arranged on the bracket; the edge frame of the film adsorbing frame is rectangular; film adsorbing net lines which are vertically and transversely interweaved are arranged inside the film adsorbing frame; the film adsorbing net lines are stuck together at each interweaving point in the film adsorbing frame; the thin film supporting roller is arranged at one side of the film adsorbing frame; the film cutting mechanism is arranged at the other side of the film adsorbing frame; a driving device and a control system are respectively arranged at the two sides of the thin film supporting roller; the springs are arrayed at the two ends of the film adsorbing frame; the springs are arranged between the film adsorbing frame and the bracket along the two ends of the film adsorbing frame through a fixing device; a film covering device and a moving mechanism thereof are arranged above the film adsorbing frame; the film covering device can move on the moving mechanism and a static induction device is arranged at the bottom of the film adsorbing frame; and the control system is respectively connected with the driving device, the static induction device, the film covering device and the film cutting mechanism through signal lines.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a novel film spreading platform. Background technique [0002] In the foundry industry, V-method molding adopts dry sand molding, known as "green casting", and has been accepted by more and more enterprises in recent years. Lamination is a key process in V-method modeling. At present, many V-method molding line lamination processes use manual stretching and manual film cutting: some pre-cut the rolled film, put it aside, and then manually lamination, which is time-consuming and laborious, and the degree of automation is very low; some will The film is hung on one end of the laminating device, and the film is manually unfolded and cut, which is not efficient, and most of them do not have specific film spreading and cutting stations. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and proposes a new type of film ...
