Description

Technical Field

[0001] The utility model relates to the technical field of PS films, in particular to an adjustable stretching cooling device for producing PS films. Background Art

[0002] Polystyrene has many advantages such as high transparency, non-toxicity, easy welding, convenient molding and processing, and low cost. However, its use as a film packaging material is limited due to its high brittleness. It was not until the application of biaxial stretching technology that biaxially oriented polystyrene film (BOPS) was produced, which effectively reduced the brittleness of polystyrene film and made its application in packaging possible. However, since polystyrene is a non-crystalline polymer, the application of biaxial stretching technology does not improve the performance of polystyrene film as significantly as that of crystalline polymers such as polypropylene. In addition, the application of biaxial stretching processing technology has weakened the economic competitiveness of polystyrene film to a certain extent, thus affecting the development of BOPS film.

[0003] However, the prior art can cool the PS film after production through a cooling device. However, when the cooling device is in use, the cooling space for the PS film is small, resulting in a slow cooling speed of the PS film, which greatly reduces the work efficiency of the user.

[0004] Therefore, the utility model provides an adjustable stretching and cooling device for PS film production. Utility Model Content

The middle section of the support frame is provided with an adjustment rod, and the middle part of the adjustment rod is connected to the connecting frame. Screws are penetrated through the connecting frame and the middle part of the adjustment rod, and a sponge cover is fitted on the outer surface of the connecting frame.

[0016] As a preferred embodiment, the adjustment components are provided in four groups.

[0017] The technical effect of adopting the above further solution is that a sponge cover is fitted on the outside of the connecting frame to protect the PS film passing through the upper end of the connecting frame, thereby preventing the PS film from being damaged by friction during transportation.

[0018] As a preferred embodiment, the shape and size of the inner wall of the cooling component are completely consistent with the shape and size of the outer wall of the PS film.
