Technical Field

[0001] The utility model relates to the technical field of hot-melt extruders, in particular to a BOPP film raw material hot-melt machine. Background Art

[0002] Biaxially oriented polypropylene film is generally a multi-layer co-extruded film, which is made by co-extruding polypropylene particles into a sheet and then stretching it in the longitudinal and transverse directions. Due to the oriented stretching molecules, this film has good physical stability, mechanical strength, and air tightness, high transparency and gloss, and is tough and wear-resistant. It is a widely used printing film.

The main body of the feeding steel pipe is fixed by multiple groups of fixing clips to reduce the damage to the connection of the feeding steel pipe caused by the vibration of the feeding steel pipe itself during the feeding process, thereby improving the practicability of the device.

[0010] Preferably, the weighing device includes a first solenoid valve, a support seat, a tension sensor, a weighing bucket and a wire rope. The first solenoid valve is installed on the output end of the storage barrel, and multiple groups of tension sensors are installed on the lower end surface of the storage barrel through multiple groups of support seats.
