[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0025] Reference Figures 1-4 A laminating machine with anti-static function includes a worktable 1. A conveyor roller 2 is installed on the top of the worktable 1. Two U-shaped plates 3 are fixed to the top of the worktable 1 by bolts. A pressure roller 8 is installed between the two U-shaped plates 3 through an adjustable height connecting assembly. A support roller 11 is rotatably connected to the top of the worktable 1. A winding assembly is provided on the top of the U-shaped plates 3. The film roll is installed on the winding assembly. One end of the film is pulled so that it passes between the support roller 11 and the pressure roller 8. Then, the height of the pressure roller 8 is changed through the connecting assembly, so that the pressure roller 8 presses the film on the steel plate. At this time, the support roller 11 supports the bottom of the steel plate, the conveyor roller 2 conveys the steel plate, and the unwinding roller 7 unwinds the film, thereby laminating the steel plate. Fixing blocks 4 are fixed to the outer walls on both sides of the worktable 1 by bolts. The interior of the fixing blocks 4... A sliding rod 15 is slidably connected, and a sliding plate 17 is slidably connected between the sliding rods 15. A metal strip 18 is fixed to the bottom of the sliding plate 17 by bolts. Both ends of the metal strip 18 are connected to grounding wires 9. A clearance hole 16 is opened inside the fixing block 4, and the grounding wire 9 passes through the clearance hole 16. A spring 19 is sleeved on the outer side of the top of the sliding rod 15, and both ends of the spring 19 are fixed to the sliding rod 15 and the sliding plate 17 respectively. The steel plate to be coated is placed on the conveyor roller 2 and passes between the support roller 11 and the pressure roller 8. At this time, the upper surface of the steel plate is in contact with the metal strip 18. The spring 19 causes the sliding plate 17 to drive the metal strip 18 to make close contact with the steel plate. The metal strip 18 can conduct the static electricity on the steel plate and lead it to the ground through the grounding wire 9. The steel plate is conveyed by the conveyor roller 2, so that the static electricity of the steel plate is removed during the coating process.

[0026] In this utility model, it should be noted that the winding assembly includes two fixing rods 6, which are respectively fixed to the side positions of the top of the two U-shaped plates 3 by bolts. A support rod 5 is fixed to the top of the fixing rod 6 by bolts. A limiting groove 14 is formed at the top of the support rod 5, and an unwinding roller 7 is placed between the limiting grooves 14. The limiting grooves 14 facilitate the disassembly of the unwinding roller 7 by the operator, thereby facilitating the disassembly and replacement of the film roll. The connecting assembly includes two sliders 13, which are slidably connected inside the two U-shaped plates 3, and a pressure roller 8 is rotatably connected between the two sliders 13. A lead screw 12 is threaded to the top of plate 3, and the bottom end of the lead screw 12 is rotatably connected to the slider 13. Rotating the lead screw 12 causes the slider 13 to move downward along the U-shaped plate 3, thereby causing the pressure roller 8 to press the film on the steel plate on the support roller 11. One side of each of the two U-shaped plates 3 is fixed with a fixing rod 6 by bolts. A guide roller 10 is rotatably connected between the fixing rods 6. The guide roller 10 can guide the film so that the film is unwound in the required direction. The support roller 11 is located at the bottom of the pressure roller 8, and the bottom end of the grounding wire 9 hangs down to the ground. The top end of the lead screw 12 passes through the U-shaped plate 3 and is welded with a knob, which makes it convenient for the operator to rotate the lead screw 12.

[0027] To perform static elimination on the surface of the coated film, L-shaped frames 20 are provided on both sides of the workbench 1 and at the rear end of the pressure roller 8. Air pipes 21 are provided on the two L-shaped frames 20, and the two ends of the air pipes 21 pass through the opposite sides of the L-shaped frames 20 respectively. Multiple air nozzles 22 are provided on the air pipes 21 at equal intervals, and the multiple air nozzles 22 are all inclined. Air can be blown onto the surface of the coated workpiece through the air pipes 21 and the multiple air nozzles 22 to eliminate static electricity on the surface.

[0028] The working principle of this utility model is as follows: In use, the steel plate to be coated is first placed on the conveyor roller 2 and passed between the support roller 11 and the pressure roller 8. Under the action of the spring 19, the upper surface of the steel plate is in close contact with the metal strip 18. The metal strip 18 can conduct the static electricity on the steel plate and lead it to the ground through the grounding wire 9. The steel plate is conveyed by the conveyor roller 2, so that the static electricity of the steel plate is removed during the coating process. Then, the film is rolled into the unwinding roller 7 and the unwinding roller 7 is locked inside the limiting groove 14. One end of the film is pulled so that it passes around the guide roller 10 and passes between the support roller 11 and the pressure roller 8. Then, the screw 12 is rotated so that the slider 13 moves down along the U-shaped plate 3, thereby pressing the film on the steel plate with the pressure roller 8. The conveyor roller 2 conveys the steel plate, and the unwinding roller 7 unwinds the film, thereby making the steel plate stably coated.

[0029] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
