V-method molding line automatic back film scraping device

Abstract

The invention discloses a V process modeling line automatic back film coating and sand scraping device, which comprises a transmission device, a film suction and sand scraping movable trolley, a film stretching and cutting device, a thin film hanger and a rack, wherein a motor of the transmission device, a trolley track of the film suction and sand scraping movable trolley and the thin film hanger are fixedly arranged on the rack; the transmission device is connected with the film suction and sand scraping movable trolley through a chain; the film suction and sand scraping movable trolley comprises an upper vacuum film suction pipe for sucking a film by using a negative pressure principle, a turning cylinder and a sand scraping plate; one end of the trolley track is connected with the film stretching and cutting device; and the film stretching and cutting device comprises a lower vacuum film suction pipe, a lifting cylinder and a film cutting resistance wire which is matched with the film stretching and cutting device. According to the V process modeling line automatic back film coating and sand scraping device, actions such as film suction, film drawing, leveling of casting sand on an upper plane of a sand box, back film coating and film cutting can be continuously and automatically finished, and the automation degree of a V process modeling line is improved; and compared with manual film cutting, manual back film coating and manual sand scraping, the time is saved, the production efficiency is increased, and the situation of high probability of causing inconsistent length size of the thin film and waste film during manual film cutting is avoided.

Description

technical field [0001] The invention relates to a molding device in a V-method molding line, in particular to an automatic backing film scraping device for a V-method molding line. Background technique [0002] The traditional operations in the V-method molding system are mostly manual film cutting, manual sand scraping, and manual backing film. In this manual operation, the operator cuts the film according to the required size in advance, and after the sand box is filled with sand, the excess sand is manually scraped off, and then the cut film is manually placed on the flattened sand box; This kind of manual operation requires a large number of people, takes a long time, and has low production efficiency. Especially in the automatic molding line, it seriously restricts the production cycle and reduces the production volume; The appearance of waste film. Contents of the invention [0003] The task of the present invention is to solve the problems existing in the prior ar...
