Description

Technical Field

[0001] This utility model relates to the field of BOPP environmentally friendly high-temperature resistant film production technology, specifically to a BOPP environmentally friendly high-temperature resistant film production device. Background Technology

[0002] BOPP stands for biaxially oriented polypropylene. The production of BOPP environmentally friendly and high-temperature resistant film is a process for manufacturing high-performance plastic films.

[0003] With the continuous development of science and technology and people's increasing demands for environmental protection, BOPP film, as a widely used packaging material, is receiving more and more attention for its environmental protection and high temperature resistance. There is a need to develop a BOPP environmentally friendly and high temperature resistant film production device to carry out the production operation of BOPP environmentally friendly and high temperature resistant film.

[0004] Chinese Patent Publication No. CN221641732U discloses "A Thin Film Production Apparatus". The thin film production apparatus includes a frame, a first cooling roller, a second cooling roller, a third cooling roller, and a swing adjustment mechanism. The first and second cooling rollers are rotatably mounted on the frame and are positioned on the same horizontal plane. The third cooling roller is mounted on the frame via the swing adjustment mechanism, which allows adjustment of the included angle formed by the first, second, and third cooling rollers. The beneficial effect of this utility model embodiment is that by changing the position of the third cooling roller through the swing adjustment mechanism, the contact angle between the product and the roller becomes adjustable, thereby changing the contact area between the product and the roller. This allows for rapid control of the product's cooling speed, effectively controlling product size, warpage, and polishing effect.

[0005] The aforementioned existing technology, by changing the position of the third cooling roller through a swing adjustment mechanism, makes the contact angle between the product and the roller adjustable, thereby changing the contact area between the product and the roller and rapidly controlling the cooling speed of the product. This achieves effective control over product size, warpage, and polishing effects. However, the existing equipment does not have the function of fully stirring the raw materials for BOPP environmentally friendly high-temperature resistant film production during use. This will affect the production quality of BOPP environmentally friendly high-temperature resistant film and reduce its reliability and durability in actual use to a certain extent.
