The signal is converted by the A / D converter and sent to the microcontroller. The display screen receives the processing signals from the microcontroller. A feeding platform 13 is mounted on one side of the housing 1. Below the feeding platform 13... A lower film cylinder 12 is provided, and an upper film cylinder 14 is installed on the other side of the cover 1. A discharge rubber roller 15 is rotatably connected to one end of the cover 1, and a guide film roller 18 is rotatably connected to the inside of the cover 1. An anti-curling plate 16 is installed inside the cover 1, located between the discharge rubber roller 15 and the guide film roller 18. A heating film coating roller 17 is installed inside the cover 1. The input end of the heating film coating roller 17 is electrically connected to the output end of the operation panel 11.

[0022] In use, the upper film tube 14 and the lower film tube 12 are respectively installed on the surface of the corresponding film frame, and the film is passed through the guide roller 18 and wound around the surface of the heating coating roller 17. When the conveying unit 21 conveys the coated part to the space between the heating coating rollers 17, the film on the surface of the upper film tube 14 contacts the surface of the coated part, and the film on the surface of the lower film tube 12 contacts the bottom of the coated part. Under the action of the heating coating roller 17, the coated part is coated on both sides. The coated part is then discharged through the guide roller 18 and the discharge rubber roller 15. At the same time, the anti-curling plate 16 prevents the coated part from curling.

[0023] Furthermore, such as Figure 1 and Figure 4 As shown, the surface of the feeding platform 13 is provided with an automatic feeding mechanism 2. The automatic feeding mechanism 2 consists of a conveying part 21, fastening bolts 22, a chute 23 and a feeding plate 24. The conveying part 21 is installed on the surface of the feeding platform 13 and is controlled by the operation panel 11. A feeding plate 24 is provided on one side of the surface of the feeding platform 13. Both ends of one side of the feeding platform 13 are provided with chute 23. The chute 23 and the feeding plate 24 slide against each other. The surface of the feeding plate 24 is threaded with fastening bolts 22. One end of the fastening bolts 22 passes through the feeding plate 24 and is pressed and fastened to the inner wall of the chute 23.

[0024] In use, loosen the fastening bolt 22, then slide the feeding plate 24 to the corresponding position with the cooperation of the slide groove 23, and then tighten the fastening bolt 22 to fix the feeding plate 24. Then place the part to be coated on the surface of the conveying part 21 inside the feeding table 13, so that one side of the conveying part 21 contacts the surface of the feeding plate 24 to prevent the coated part from being skewed. Then control the operation of the conveying part 21 through the operation panel 11. Under the action of the conveying part 21, the coated part is automatically conveyed to realize the automatic feeding and conveying function of the coating device.

[0025] Furthermore, such as Figure 3 As shown, a dotting and slitting mechanism 3 is provided above the upper film cylinder 14. The dotting and slitting mechanism 3 includes a dotting and slitting assembly 31 and a support rod 32 inside. The support rod 32 is fixed above the cover 1 by a spring rod.

The dotting and slitting assembly 31 consists of a pressure roller 311, a connecting rod 312, a slip ring 313, a locking stud 314, a pre-coated film dotting knife 315, a pre-coated film slitting knife 316, and a guide groove 317. The surface of the support rod 32 is provided with a guide groove 317. Slip rings 313 are slidably provided on both sides of the surface. Locking studs 314 are threadedly connected to the surface of slip rings 313. One end of locking studs 314 passes through slip rings 313 and is pressed and fastened to the inner wall of guide grooves 317. A connecting rod 312 is fixed to one side of slip rings 313. A pressure roller 311 is rotatably connected to one end of connecting rod 312. A pre-coated film slitting knife 316 is rotatably connected to one end of connecting rod 312. A pre-coated film dotting knife 315 is rotatably connected to one end of connecting rod 312. The pre-coated film dotting knife 315 is located on one side of the pre-coated film slitting knife 316.

[0026] In use, after the upper film cylinder 14 is installed, the locking stud 314 can be loosened, and then the sliding ring 313 can be slid as needed to move the connecting rod 312, so that the pre-coated film dotting knife 315 moves to the corresponding position. When the film passes under the pre-coated film dotting knife 315, a row of small holes can be rolled out on the edge of the pre-coated film under the action of the pre-coated film dotting knife 315 to facilitate the cutting of the film-coated parts after film coating. Similarly, under the action of the pre-coated film slitting knife 316 on the other side, it can be used to cut wide and long film rolls. Since the dotting and cutting mechanism 3 is fixed by the elastic rod, it is convenient for the pre-coated film dotting knife 315 and the pre-coated film slitting knife 316 to always be in contact with the film roll, so as to realize the dotting and cutting function of the film roll by the film coating device.

[0027] Working principle: In use, first loosen the fastening bolt 22, then slide the feeding plate 24 to the corresponding position with the cooperation of the slide groove 23, and then tighten the fastening bolt 22 to fix the feeding plate 24. Then place the part to be coated on the surface of the conveying part 21 inside the feeding table 13, so that one side of the conveying part 21 contacts the surface of the feeding plate 24 to prevent the coated part from being skewed. Then control the operation of the conveying part 21 through the operation panel 11. Under the action of the conveying part 21, the coated part is automatically conveyed to realize the automatic feeding and conveying function of the coating device, thereby improving the working efficiency of the coating device during feeding and conveying.

[0028] At this time, the upper film tube 14 and the lower film tube 12 are respectively installed on the surface of the corresponding film frame, and the film passes through the guide roller 18 and winds around to the surface of the heating coating roller 17. When the conveying unit 21 conveys the coated part to the space between the heating coating rollers 17, the film on the surface of the upper film tube 14 contacts the surface of the coated part, and the film on the surface of the lower film tube 12 contacts the bottom of the coated part. Under the action of the heating coating roller 17, the coated part is coated on both sides. The coated part is then discharged through the guide roller 18 and the discharge rubber roller 15. At the same time, the anti-curling plate 16 can prevent the coated part from curling.

[0029] Meanwhile, after the upper film cylinder 14 is installed, the locking stud 314 can be loosened, and the sliding ring 313 can be slid according to the requirements, so that the sliding ring 313 drives the connecting rod 312 to move, so that the pre-coated film dotting knife 315 moves to the corresponding position. When the film passes under the pre-coated film dotting knife 315, a row of small holes can be rolled out on the edge of the pre-coated film under the action of the pre-coated film dotting knife 315 to facilitate the cutting of the film-coated parts after film coating. Similarly, under the action of the pre-coated film slitting knife 316 on the other side, it can be used to cut wide and long film rolls. Since the dotting and cutting mechanism 3 is fixed by the elastic rod, it is convenient for the pre-coated film dotting knife 315 and the pre-coated film slitting knife 316 to always be in contact with the film roll, so as to realize the dotting and cutting function of the film roll of the film coating device, which is more functional and finally completes the use of the film coating device.
