Plastic sheets need to be filmed to improve the appearance and quality of the product and prevent scratches and contamination during transportation and assembly. When filming plastic sheets, a film laminating machine is required.

[0003] The patent with announcement number CN217373474U discloses a sheet film laminating machine, comprising a main frame, a side frame body is fixedly installed on the outer side of the center of the main frame body, the main frame body is equipped with rotating rollers located on both sides of the side frame body, and a sheet is placed on the top of the main frame body, the main frame body is equipped with a lower film laminating roller located below the sheet, the side frame body is equipped with an upper film laminating roller located above the sheet, and the top of the side frame body is equipped with a film roller, the film roller is wound on the film roller, and the film roller has the same specifications as the upper film laminating roller; the sheet film laminating machine, through the arrangement of a driving motor inside the side frame body, can drive the lower film laminating roller to drive the sheet to move on the top of the rotating roller through a chain, and the upper film laminating roller above the sheet also rotates accordingly, and at this time, the film wound on the upper film laminating roller will automatically wrap around the outer wall of the sheet, thereby achieving the effect of fully automatic film laminating on the sheet, solving the problems of low efficiency and large waste of labor in manual film laminating of existing devices.

[0004] The above-mentioned existing technology can apply film to the surface of the plate, but it is not easy to align the plate with the upper film-laminating roller during the film-laminating process, and there is an offset problem, which affects the processing efficiency and processing quality. In view of this, we propose a plastic plate film-laminating machine with precise positioning. Utility Model Content

[0005] The purpose of the utility model is to provide a plastic plate film laminating machine with accurate positioning to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The plastic sheet laminating machine with accurate alignment comprises a frame frame, wherein a conveying roller is rotatably connected between the front and rear sides of the inner wall of the frame frame and located in the middle, and a motor for driving the conveying roller to rotate is arranged at the front side of the frame frame, and the motor is connected to an external power supply to work, and the conveying roller is driven to rotate by the motor, and the conveying roller can drive the plastic sheet to move to the right;

[0008] The top end of the two movable connecting rods is provided with an anti-slip block, and the anti-slip block can prevent the movable connecting rod from slipping off the movable cross plate. The outer wall of the movable connecting rod is provided with a spring, and the bottom end of the two movable connecting rods is commonly connected with a U-shaped movable plate, and the film pasting roller is rotatably connected in the U-shaped movable plate, and the top of the left side of the two fixed vertical plates is provided with a first fixed cross bar, and a film roller is movably connected between the two first fixed cross bars, and the film roller is used for film roll sleeve arrangement;

[0009] The movable horizontal plate is driven to move up and down by the threaded rod, so that the movable horizontal plate can adjust the height of the two movable connecting rods, and then adjust the height of the U-shaped movable plate and the film-laminating roller. The film-laminating roller is located directly above the conveying roller. The height adjustment of the film-laminating roller can adapt to plastic sheets of different thicknesses. When laminating the plastic sheet, the distance between the film-laminating roller and the conveying roller is slightly smaller than the thickness of the plastic sheet, so that the film-laminating roller can exert a certain pressure on the plastic sheet under the action of the spring, so that the film is attached to the surface of the plastic sheet;

The positioning slider is slidably connected to the outer side of the positioning cross bar, which is conducive to the forward and backward movement of the positioning slider, so that the rectangular plate can only move forward and backward, and the stability of the rectangular plate is improved.

[0018] Preferably, a hand wheel is rotatably connected to the outer side of one of the second fixed cross bars, and the rotating shaft of the hand wheel is coaxially connected to one end of the bidirectional screw rod, so that the staff can rotate the bidirectional screw rod conveniently.

[0045] When the plastic sheet film laminating machine with precise alignment of the present embodiment is in use, the staff first adjusts the distance between the film laminating roller 67 and the conveying roller 4 according to the thickness of the plastic sheet to be filmed. Specifically, the staff places the plastic sheet on the conveying roller 4, and then rotates the threaded rod 63, so that the threaded rod 63 drives the movable horizontal plate 64 to move downward, and the movable horizontal plate 64 drives the two movable connecting rods 65, the U-shaped movable plate 66 and the film laminating roller 67 to move downward synchronously, until the top ends of the two movable connecting rods 65 move up 1-3 mm relative to the movable horizontal plate 64, so that the spring 68 is compressed, and the spring 68 generates a downward thrust on the U-shaped movable plate 66, so that the film laminating roller 67 generates pressure on the upper surface of the plastic sheet; then the staff adjusts the two rectangular plates according to the width of the plastic sheet. 73, specifically, the staff rotates the hand wheel 78 to make the hand wheel 78 drive the bidirectional screw rod 71 to rotate, the bidirectional screw rod 71 drives the two moving blocks 72 to move synchronously relative to each other, and the two moving blocks 72 respectively drive the two rectangular plates 73 to move until the outer walls of the guide wheels 75 on the two moving blocks 72 respectively abut against the front and rear sides of the plastic sheet; when the plastic sheet is to be filmed, the staff starts the motor 5, then places the plastic sheet on the first rotating roller 2, and passes the plastic sheet through the two rectangular plates 73. When the plastic sheet contacts the conveying roller 4, the conveying roller 4 can drive the plastic sheet to move to the right because the motor 5 drives the conveying roller 4 to rotate. At the same time, the film pasting roller 67 adheres the film to the upper surface of the plastic sheet to realize the film pasting operation of the plastic sheet.
