Problems solved by technology
[0003] However, the blow molding machine of the prior art cannot guarantee that the overall thickness of the blown film is completely consistent. At this time, wrinkles and the like will easily occur during subsequent stretching and winding, and the problem of wrinkles is often solved by stretching in the prior art. Tight stretching is completed, but the pleated stretching of the existing technology cannot guarantee the precise stretching of the film in real time, so it is easy to lead to poor quality of subsequent products

Embodiment
[0036] refer to Figure 1-5 , a thermoplastic film production and processing device and method, comprising a frame 1, two groups of roll bodies are rotatably connected in the frame 1: the first set of roll bodies is composed of a first intermediate roll 4 and a second intermediate roll 5, and the second set of rolls The body is a receiving roller 6 composed of two roller bodies; the two groups of roller bodies work together to fix the thermoplastic film on the device of the present application;
[0037] The first intermediate roll 4 includes a first outer roll ring 41 and a first inner roll body 42 that are relatively slidingly connected, and the second intermediate roll 5 includes a second outer roll ring 51 and a second inner roll body 52 that are relatively slidingly connected; When the film is wrinkled due to abnormalities in the blow molding stage, the compression spring 46 will stretch so that the first outer roller ring 41 moves relative to the first inner roller body 4...

The invention discloses a thermoplastic film producing and processing device and method. The thermoplastic film producing and processing device comprises a rack, two groups of roller bodies are rotationally connected in the rack; the first group of roller bodies is composed of a first middle roller and a second middle roller, and the second group of roller bodies is a material receiving roller composed of two roller bodies; each of the two roller bodies of the material collecting roller is fixedly connected with a material collecting gear; the two material collecting gears mesh with each other; one material collecting gear is coaxially and fixedly connected with a synchronous wheel; a power box is fixedly connected to the side wall of the rack; a driving motor is fixedly connected to the outer side wall of the power box; and a set of synchronous gears meshing with each other are arranged in the power box. The device and the method have the advantages that the access current of a metal spring can be controlled in real time, so that the tension degree of a thin film is controlled, then the reciprocating motion of a sliding column is controlled, thus the transmission speed of two power circular truncated cones is changed, the tension degree of the thin film is finally adjusted, it is guaranteed that a worker has enough control authority, and the device is conveniently controlled in real time.
Description
technical field [0001] The invention relates to the technical field of film production, in particular to a thermoplastic film production and processing device and method. Background technique [0002] When thermoplastic film is produced, liquid plastic is sprayed out, and the plastic body is blown and attached to a mold cavity of a certain shape by using the wind blown out by the machine to make a product. This equipment is called a blow molding machine; film blow molding The machine does not need a mold cavity. After the cylindrical film prototype is blown out by wind force, the corresponding rolling parts will roll the cylindrical film into a double-layer flat film to realize the production of the film. [0003] However, the blow molding machine of the prior art cannot guarantee that the overall thickness of the blown film is completely consistent. At this time, wrinkles and the like will easily occur during subsequent stretching and winding, and the problem of wrinkles is...
