Abstract

The invention relates to film machining equipment, in particular to film blowing equipment. According to the technical scheme, the film blowing equipment comprises a machine body, a plastic particle charging hopper arranged on the machine body, a plastic particle heating melting device, a film blowing device, a stretching tidying device and a rolling device. The film blowing device comprises a film blowing barrel and a die. A die rod extending to the outside is arranged in the film blowing barrel and comprises a rod body connected with the film blowing barrel, and a guiding sleeve. The stretching tidying device comprises a support and a plurality of adjustable roll shafts erected on the support. The rod body is a hollow rod body and is internally provided with an air way. The rod body is provided with a plurality of air holes communicating with the inner air way of the rod body. Communicating through holes corresponding to the positions of the air holes are formed in the lower portion of the guiding sleeve, and a sealing assembly is arranged between each of the two axial ends of the guiding sleeve and the rod body. By the adoption of the above technical scheme, the film blowing equipment preventing bonding of a film and the roll shafts, preventing film damage, making film guidance stable and improving the machining quality is provided.

Description

technical field [0001] The invention relates to a film processing equipment, in particular to a film blowing equipment. Background technique [0002] The film blowing machine is a processing equipment that heats and melts plastic particles, and then blows them into films. The traditional film blowing machine is mainly composed of a body, a plastic particle feeding hopper on the body, a plastic particle heating and melting device connected with the plastic particle feeding hopper, a film blowing device connected with the plastic particle heating and melting device, and a film blowing device. A stretching finishing device and a winding device connected with the stretching finishing device. [0003] The traditional blown film device mainly consists of a blown film cylinder and a mold inside the blown film cylinder. The blown film cylinder is equipped with a mold rod extending to the outside. The mold rod is mainly used to accumulate the blown film to achieve lamination. and o...
