Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film preparation, in particular to a film heating device. Background Art
[0002] In the plastic film manufacturing industry, winding is one of the processes. The film is wound into a coil by a winder, which can effectively reduce the space occupied and facilitate transportation. However, when producing film in winter, the film cannot reach the degree of natural shrinkage in a short time due to the low natural temperature (the natural shrinkage generally ranges from 7 to 10 mm), resulting in residual stress in the film. The film may deform during winding, which affects the quality of the finished coil.
[0003] Film heating requires the use of a heating roller. One end of the film is wound around the heating roller and the film is heated by the heating roller. However, the size of the heating roller is fixed, which results in a limited contact area between the film and the heating roller. At the same time, the contact time between the film and the surface of the heating roller is also limited, and the film cannot be fully heated. In addition, if the film is wrinkled during transportation, it will affect the heating of the film. Utility Model Content
[0004] The purpose of the utility model is to provide a thin film heating device to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0014] 1. In the utility model, the film enters the box from the feed port, and the two feed rollers are used to press the film. After the film is heated, it is discharged from the discharge port. The two discharge rollers are used to press the heated film. Before the film is heated, the height of the first tension roller and the second tension roller can be adjusted respectively by the cooperation of the two first electric push rods and the two second electric push rods, and the height difference between the first tension roller and the second tension roller can be changed. The film first bypasses the first tension roller and then bypasses the second tension roller. The tension of the film is adjusted by the height change between the two tension rollers, so that the film is not wrinkled and is smoother, which is conducive to the heating of the film;
[0015] 2. In the utility model, the pressure roller can move toward the side close to the film until it squeezes the film so that the film is more closely attached to the heating roller. Under normal circumstances, the pressure roller does not contact the film. When the film needs to be heated more fully, the third electric push rod can be controlled to push the pressure roller toward the film and fully squeeze the film. At this time, one end of the film will be bent, and the contact area between the film and the heating roller will be larger and the contact time will be longer, which is conducive to fully heating the film.
[0016] 3. In the utility model, the mounting plate and the mounting block are elastically connected by using multiple springs and multiple telescopic rods. The provided base can buffer the pressure and vibration generated when the electric push rod pushes the roller to extrude the film, and the original hard contact between the roller and the film is changed to the current soft contact, thereby avoiding the problem of damage to the film caused by hard contact between the roller and the film. The film is not easily damaged and the processing effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A bending mechanism 9 is provided on one side of the box body 1 near the discharge port 5, and the tension adjusting mechanism 4 is used to adjust the tension of the film. The bending mechanism 9 can squeeze the film to one side to increase the contact area and contact time between the film and the heating roller. A heating roller 10 is provided between the tension adjusting mechanism 4 and the bending mechanism 9. The heating roller 10 is rotatably connected to the box body 1 through two bearing seats 12. The heating roller 10 is used to heat the film. A traction roller 8 is installed on one side of the top of the box body 1 near the discharge port 5. A motor 7 is installed on one side of the top of the box body 1 corresponding to the traction roller 8. One end of the output shaft of the motor 7 is fixedly connected to one end of the rotating shaft of the traction roller 8. The traction roller 8 is used to traction the film, and the motor 7 provides power for traction of the film.
[0030] See also Figure 4 The tension adjustment mechanism 4 includes two first electric push rods 41 and two second electric push rods 42. The output ends of the two first electric push rods 41 and the output ends of the two second electric push rods 42 are fixed with a base 11, and the two bases 11 on the adjacent side are set as a group. The first tension roller 43 and the second tension roller 44 are rotated between the two groups of bases 11 through the bearing seat 12 respectively. The height of the first tension roller 43 and the second tension roller 44 can be adjusted respectively by the coordinated use of the two first electric push rods 41 and the two second electric push rods 42, and the height difference between the first tension roller 43 and the second tension roller 44 can be changed.
