Description

Technical Field

[0001] This utility model relates to the field of coating device technology, specifically a coating device for tin-plated thin plates. Background Technology

[0002] A tinplate coating apparatus is a specialized device used to coat the surface of tinplate with a protective film, designed to improve its corrosion resistance and extend its service life. This apparatus is commonly used in the metalworking industry, particularly in the production of food cans, beverage cans, and other packaging materials requiring high corrosion resistance.

[0003] Chinese utility model patent CN217258403U discloses a high-efficiency coating device for thin metal sheets. Although it can calculate the rotation speed of the material roller based on the rotation speed of the first gear through an encoder, and control the motor operation by analyzing the signal received by the encoder through a single-chip microcomputer to keep the film on the material roller in a tense state, this high-efficiency coating device for thin metal sheets has the disadvantages of relatively complex structure and the inability to guarantee the film's tense state while not guaranteeing the film coating quality well.

[0013] This utility model provides a coating device for tin-plated thin plates, which has the following beneficial effects:

[0014] 1. This tinplate coating device, through the setting of the rotating shaft fixing hole, enables the angle and direction of the stretching rod to be adjusted by inserting the rod into the fixing hole at different positions.

[0022] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example

[0024] Please see Figures 1 to 5 The present invention provides a technical solution: a tin-plated sheet coating device, comprising a base plate 1, a support block 2 fixedly connected above the base plate 1, a winding reel 3 rotatably connected to one end of the support block 2, a film reel support arm 4 fixedly connected to the middle of the base plate 1, a fixing sleeve 5 fixedly connected to the front of the film reel support arm 4, a rotating shaft 6 rotatably connected inside the fixing sleeve 5, a connecting arm 8 fixedly connected to one end of the rotating shaft 6, a tension rod 9 rotatably connected to the back of the connecting arm 8, a cooling box 17 fixedly connected to the right side of the film reel support arm 4, a guide rod 20 rotatably connected to the right side of the cooling box 17, a second motor 21 fixedly connected to the right end of the base plate 1, and a winding reel 22 rotatably connected to the front of the second motor 21.

[0025] Specifically, the stretching rod 9 can straighten the film to prevent wrinkles during lamination. The pivot 6 can adjust the position of the stretching rod 9 to regulate the tension of the film, thus ensuring the quality of film lamination. The cooling box 17 allows the film to be cooled after lamination, resulting in a tighter bond. The guide rod 20 keeps the thin plate suspended during cooling, preventing it from sticking and breaking upon contact with the box.

[0026] Please see Figures 1 to 3 A fixing hole 501 is provided above the fixing sleeve 5. A rod 7 is provided inside the fixing hole 501. A shaft fixing hole 601 is provided on the outer surface of the rotating shaft 6. There are several shaft fixing holes 601, which are evenly distributed in a circular array on the outer surface of the rotating shaft 6. A diaphragm disk 10 is rotatably connected above the diaphragm disk support arm 4. A fixing block 11 is fixedly connected to the middle of the diaphragm disk support arm 4. A fixing rod 16 is rotatably connected to the front of the fixing block 11. An electric heating wire is provided inside the fixing rod 16. A lead screw 13 is threadedly connected inside the fixing block 11. A movable block 12 is rotatably connected to the outer surface of the lead screw 13. A motor 14 is fixedly connected to the front of the movable block 12. A movable rod 15 is rotatably connected to the front of the motor 14. The movable rod 15 is made of rubber.

[0027] Specifically, the lead screw 13 enables the tinplate coating device to clamp the thin plate and film, making the coating process easier. The rotating shaft fixing hole 601 allows the angle of the stretching rod 9 to be adjusted by inserting the rod 7 into the fixing hole at different positions. Through the cooperation of the stretching rod 9 and the movable rod 15, the film can be stretched by the stretching rod 9 during use, so that the film can be tightly adhered at the movable rod 15 by cooperating with the fixed rod 16. This results in a smoother adhesion between the film and the thin plate, thus improving the quality of the thin plate coating.

[0028] Please see Figures 4 to 5 The cooling box 17 has a cooling port inside. The cooling port has a trapezoidal cross-section with the longer side facing upwards. A through groove is provided below the cooling port, and the lower end of the cooling port is connected to the through groove. A ventilation port is provided above the cooling box 17. A connecting rod 18 is fixedly connected inside the ventilation port. An exhaust fan motor is fixedly installed in the middle of the connecting rod 18. An exhaust fan 19 is rotatably connected to the bottom of the exhaust fan motor and is installed inside the cooling port.

[0029] Specifically, through the coordinated arrangement of the cooling box 17 and the guide rod 20, during the winding process controlled by the motor 21, the coated sheet can be supported by the guide rod 20, allowing the coated sheet to be suspended in the cooling box 17 for cooling. This prevents the film from being damaged due to contact with the box body while shrinking, thus achieving the purpose of cooling the coated sheet and ensuring that the film shrinks and adheres tightly, thereby improving the quality of the sheet coating.

[0030] In use, the thin sheet is first pulled out from the unwinding reel 3 and pulled to the fixed rod 16. Then, the film is passed through the film reel 10, around the stretching rod 9, and stretched to the same point on the fixed rod 16. After stretching, the movable rod 15 is pressed down by rotating the lead screw 13, so that the film and the thin sheet are tightly bonded. Due to the heating wire structure inside the fixed rod 16, the thin sheet can be heated, so that the film can better cover the thin sheet after bonding. The motor 14 is started, and the thin sheet will move towards the take-up reel 22 by friction of the movable rod 15. The exhaust fan 19 is started, so that the air inside the cooling box 17 is circulated, thereby cooling the thin sheet and film, making the film shrink and bond more tightly, and improving the bonding quality. After cooling, the thin sheet is led out through the bottom of the guide rod 20 and wound onto the take-up reel 22. Once wound, the preparation is complete. Then, simply start the motor 21 to move the thin sheet towards the take-up reel 22. At this time, the thin sheet and film are heated and bonded at the movable rod 15 and fixed rod 16. Then, it is suspended in the cooling box 17 for cooling and shrinkage. After cooling, it is finally wound onto the take-up reel 22 through the bottom of the guide rod 20. If wrinkles occur during film bonding, simply adjust the angle of the tension rod 9 through the pivot fixing hole 601 so that the left end of the tension rod 9 moves downward. If a breakage occurs, simply adjust the angle of the tension rod 9 so that the left end of the tension rod 9 moves upward.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
