Description

Technical Field

[0001] The utility model relates to the technical field of tape processing, in particular to a film blowing device for tape processing. Background Technique

[0002] A tape is composed of two parts: a base material and an adhesive. By bonding, two or more non-connected objects can be joined together. There is an adhesive layer on its surface. In tape processing, the film blowing device is used for the production of the tape base material. The film blowing device is a processing technology that heats and melts plastic particles and blows them into a film. Its core lies in heating and melting the plastic raw materials, using a screw extruder to extrude the melt into a tubular film blank. When the melt is in a good flow state, the tubular film is blown up to the required thickness by high-pressure air, and after cooling and shaping, it becomes a film product.

[0003] A Chinese patent discloses a film blowing device (authorization publication number CN211518481U). Through the provided flow guide plate, it can play a role in equalizing the air flow and forming air pressure, thereby improving the uniformity of the air flow. Through the evenly distributed air outlet holes, the cooling of the formed film can be more uniform, and the thickness of the formed film can be more uniform. Through the provided drive motor, the drive motor drives the grinding roller to rotate, and can grind and crush the materials in the feed hopper, making the materials easier to be melted. However, when the materials of the above film blowing device are transported to the film blowing position, they will solidify and block due to too fast cooling, affecting the smoothness of film blowing, being not conducive to the film blowing effect. The blowing size of film blowing is fixed, the intensity of film blowing is relatively single, being not conducive to the flexibility of film blowing operation, and the accuracy of film blowing thickness control is relatively low. Therefore, the technical personnel in this field provide a film blowing device for tape processing to solve the problems raised in the above background technique. Summary of the Utility Model
