Film pasting machine for rock wool boards

Abstract

A film laminating machine for rock wool boards according to the present invention comprises a frame, the front end of the frame is provided with an active conveying roller, the rear of the active conveying roller is driven and connected with a parallel driven laminating roller, and the upper part of the driven laminating roller is provided with a feeding roller. Film roller, there is a rubber coating cylinder between the driven film roller and the film supply roller; behind the driven film roller, there are two transmission rollers located above the rock wool board transmission channel, and there are metal rollers between the two transmission rollers. The crawler track, the inner side of the metal crawler track is provided with a heating device and a cooling device, and the heating device is located in front of the cooling device. The beneficial effects of the present invention are: the present invention can not only evenly apply glue to the aluminum foil, but also carry out the hot pressing and cooling process, and can also scrape off the overflowing glue in time, thereby greatly improving the efficiency and quality of the film sticking.

Description

technical field [0001] The invention relates to a film pasting machine for rock wool boards. Background technique [0002] At present, rock wool is made of natural basalt as the main raw material, which is made through high-temperature melting, fiber spinning, and pressure curing. It has good thermal insulation, fire prevention, sound absorption and noise reduction and other functions, and is widely used in construction, thermal Pipelines, industrial equipment and vehicles and many other fields. The rock wool board is easy to volatilize dust during the process of handling and construction, causing itchy skin of the staff. In addition, the surface of the rock wool exposed to the air is easy to pulverize, absorb water and get damp, which greatly shortens the service life of the rock wool. The cotton surface is treated to solve the above unfavorable factors. The current method is to stick aluminum foil on the rock wool surface. The film sticking equipment generally includes a ...

AI Technical Summary

Problems solved by technology

Traditional hot pressing devices usually use hot pressing rollers, that is, hot pressing rollers are installed on the upper and lower sides of the rock wool board and aluminum foil to roll it. Since the hot pressing roller and the board are in linear contact, the contact area is relatively small. Small, poor pressurization effect, if the pressure between the hot pressing rollers is not enough or the pressure is not uniform, the board with the film will easily produce air bubbles, which will affect the quality of the film. In addition, the rock wool board after the film needs to go through the cutting section. The cutting part forms a bulge, which affects the quality of the film. If multiple sets of hot-pressing rollers are installed for rolling, the cost of the hot-pressing roller is high, which increases the production cost.

[0004] In addition, the traditional glue sizing device is not easy to maintain, because the glue sizing device is controlled by the scraper to control the amount and uniformity of the aluminum foil. This structure has high requirements for the material of the scraper and its assembly position. With the operation of the production line, The tightness between the scraper and the aluminum foil needs to be adjusted frequently; if the scraper is too hard, it will wear the aluminum foil; if the scraper is too soft and not durable, it will be easily worn after a period of use. If it is not replaced in time, it will affect the uniformity of the glue coating. Therefore, The uneven glue application caused by the scraper will affect the subsequent hot pressing process, which will also lead to poor film sticking effect
