[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-3This utility model provides a technical solution: it includes a frame 1, inside which a belt conveyor 2 is installed, and columns 3 are fixedly installed on the front and rear sides of the top of the frame 1. Vertical holes 16 are opened on the columns 3, and sliders 17 are vertically slidably connected inside the vertical holes 16. A lead screw 18 is rotatably connected inside one of the vertical holes 16, passing through the slider 17 and threadedly connected to it. An installation rod 4 is fixedly installed between the two sliders 17, and an installation plate 5 is fixedly connected to the bottom of the installation rod 4. The lower side of the installation plate 5... A sponge block 6 is provided. The bottom of the mounting plate 5 has several T-shaped holes 20. The top of the mounting plate 5 is slidably connected to a vertical shaft 21. The lower end of the vertical shaft 21 is inside the T-shaped holes 20. The upper end of the vertical shaft 21 is fixedly connected to a disc 22. A spring 23 is sleeved on the vertical shaft 21. The upper and lower ends of the spring 23 are fixedly connected to the top of the mounting plate 5 and the bottom of the disc 22, respectively. The top of the sponge block 6 is fixedly connected to several T-shaped blocks 24 that match the T-shaped holes 20. The top of the T-shaped blocks 24 has round holes 25 that match the vertical shaft 21.

[0028] In this technical solution, by applying an upward force to the disc 22, the vertical shaft 21 stretches the spring 23 and moves upward. Then, the T-block 24 slides into the T-hole 20. The spring force of the spring 23 drives the vertical shaft 21, so that the lower end of the vertical shaft 21 is inserted into the round hole 25, thus completing the installation of the sponge block 6 and facilitating the replacement of the sponge block 6. Furthermore, by rotating the lead screw 18, the slider 17 moves downward, which in turn drives the sponge block 6 downward through the mounting rod 4. This allows the sponge block 6 to come into contact with the product to be coated conveyed on the belt conveyor 2, thereby removing dust from the product to be coated and preventing dust from adhering to the product and affecting the coating effect.

[0029] In some technical solutions, such as Figure 1 and Figure 4 As shown, a bracket 7 is fixedly installed on the top of the frame 1. Support rods 8 are fixedly installed on the front and rear sides of one side of the bracket 7. A raw material roller 9 is rotatably installed between the two support rods 8. The raw material roller 9 is wrapped with a polyester film 10. Through holes 12 are opened on the front and rear sides of the bracket 7. A servo motor 13 is fixedly installed on the front top of the bracket 7. A second slider 26 is vertically slidably connected inside the through hole 12. A film-coating heating roller 11 is rotatably installed between the two second sliders 26. A second lead screw 27 is rotatably installed inside one through hole 12. The upper end of the second lead screw 27 is installed with the output end of the servo motor 13. The second lead screw 27 passes through the second slider 26. The second slider 26 and the second lead screw 27 are threadedly connected.

[0030] In use, the polyester film 10 on the raw material roller 9 is laid on the coated product, and then the servo motor 13 drives the lead screw 27 to rotate. The lead screw 27 drives the coating heating roller 11 to move downward through the slider 26, so that the coating heating roller 11 comes into contact with the coated product and the polyester film 10 is coated on the product. It is convenient to use and can be continuously coated, with high work efficiency.

[0031] In some technical solutions, such as Figure 2 As shown, the upper end of the lead screw 18 passes through the top of the column 3 and is fixedly installed with a handwheel 19.

[0032] When in use, the lead screw 18 can be easily rotated via the handwheel 19.

[0033] In some technical solutions, such as Figure 4 As shown, a guide roller 28 is rotatably mounted on the upper side inside the bracket 7.

[0034] In use, the guide roller 28 can catch the released polyester film 10, preventing the polyester film 10 not laid on the coated product from coming into contact with the coating heating roller 11.

[0035] In some technical solutions, such as Figure 1 As shown, a collection box 14 is fixedly installed on one side of the bottom of the frame 1.

[0036] When in use, the coated products can be easily collected through the collection box 14.

[0037] In some technical solutions, such as Figure 1 As shown, several support legs 15 are fixedly connected to the outer edge of the bottom of the frame 1, and anti-slip pads are fixedly connected to the bottom of the support legs 15.

[0038] When in use, the anti-slip pads on the bottom of the support legs 15 increase the stability of the film covering device.

[0039] Working principle: During use, an upward force is applied to the disc 22, causing the vertical shaft 21 to stretch the spring 23 and move upward. Then, the T-block 24 slides into the T-hole 20. The spring force of the spring 23 drives the vertical shaft 21, causing the lower end of the vertical shaft 21 to be inserted into the round hole 25, thus completing the installation of the sponge block 6 and facilitating the replacement of the sponge block 6. By rotating the lead screw 18, the slider 17 moves downward, which in turn moves the sponge block 6 downward through the mounting rod 4, so that the sponge block 6 comes into contact with the product to be coated on the belt conveyor 2, thus removing dust from the product to be coated. During the coating process, the polyester film 10 on the raw material roller 9 is laid on the coated product after dust removal. Then, the servo motor 13 drives the lead screw 27 to rotate, and the lead screw 27 drives the coating heating roller 11 downward through the slider 26, so that the coating heating roller 11 comes into contact with the conveyed coated product, thus coating the product with the polyester film 10. It is convenient to use and can be coated continuously.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
