DETAILED DESCRIPTION

[0019] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0020] Example

[0021] See also Figure 1-4 ,The utility model provides a technical solution: a PVC sheet laminating device;

[0022] This case aims to provide a laminating device that is conducive to cleaning PVC sheets and cutting films. Existing PVC sheets will have dust and debris left, affecting the laminating effect. At the same time, the film between the PVC sheets needs to be cut manually, which is inefficient.

[0023] Based on the above problems, the components in this case include a base 1, a conveyor belt 2 is installed on the top of the base 1, a reeling roller 3 is installed on the middle part of the top of the base 1, a conveying roller 4 is installed on the middle part of the top of the base 1, a compacting roller 5 is provided on the middle part of the top of the base 1, a fixing frame 6 is installed on the rear side of the top of the base 1, a screw 7 is rotatably connected to the upper side of the fixing frame 6, an adjusting motor 8 is connected to one end of the screw 7, a sliding seat 9 is threadedly connected to the screw 7, a cutting knife 10 is installed on the bottom of the sliding seat 9, an unwinding motor 11 is connected to one end of the conveying roller 4, and a dust removal component is installed on the front side of the top of the base 1;

[0024] The dust removal assembly includes: a dust collecting cover 12, a lifting plate 13, a cleaning brush 14, two springs 15, a dust removal box 16 and an exhaust fan 17;

[0025] The dust hood 12 is installed on the front side of the top of the base 1. Bar blocks are provided on both sides of the bottom of the dust hood 12. A cavity is provided inside the bar blocks. One end of two springs 15 is connected to the wall surface of the bottom of the cavity. Both ends of the lifting plate 13 are inserted into the cavity and connected to the other end of the spring 15. A dust removal box 16 is installed on the top of the dust hood 12. An exhaust fan 17 is connected to the inside of the dust removal box 16.

[0026] It should be noted that the PVC sheet is first placed on the top of the conveyor belt 2 and transported by the conveyor belt 2. During the transportation process, the spring 15 will pull down the lifting plate 13, and make the cleaning brush 14 located at the bottom of the lifting plate 13 contact with the surface of the PVC sheet. As the conveyor belt 2 moves with the PVC sheet, the cleaning brush 14 can clean the surface of the PVC sheet. At the same time, the exhaust fan 17 is running, and the bottom opening of the dust collecting cover 12 can be used to attract the remaining dust and the dust generated by the cleaning brush 14, and the dust is collected by the dust removal box 16, so as to finally achieve the purpose of dust removal on the surface of the PVC sheet.

[0027] Then the PVC sheet moves to the bottom of the conveying roller 4, and the unwinding motor 11 runs at the same time, so that the film can be extracted from the unwinding roller 3 and covered on the surface of the PVC sheet, and then the film is compacted by the compacting roller 5. Since the present case is a continuous coating operation, the film on the surface of each PVC sheet is a whole, so it is necessary to cut the film between the PVC sheets. Therefore, the motor 8 is adjusted to run, and the sliding seat 9 and the cutting knife 10 are driven by the screw 7 to move at the bottom of the fixed frame 6, and the initial position of the cutting knife 10 is the right side of the fixed frame 6, and the right side of the fixed frame 6 is close to the compacting roller. When the PVC sheet moves, the cutting knife 10 can keep relatively moving, and the moving film can be horizontally cut;

[0028] At this time, the conveyor belt 2 does not need to stop, and can continuously and uninterruptedly perform laminating and cutting operations on the PVC sheet, which has the advantages of good laminating effect and high operating efficiency;

[0029] The limiting roller 18 can limit the position of the PVC sheet located at the top of the conveyor belt 2 to prevent the PVC sheet from being displaced when moving on the top of the conveyor belt.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
