Description

Technical Field

[0001] This utility model relates to the field of paper liner production technology, specifically to an adjustable coating device for paper liner surface treatment. Background Technology

[0002] Liner paper is a special type of paper that provides protection through physical isolation. It is mainly used in industrial material protection and printing and packaging. In the industrial field, stainless steel liner paper and aluminum plate liner paper prevent metal materials from being scratched during processing and transportation due to their high temperature resistance and high tensile strength. Sulfur-free liner paper for printed circuit boards can prevent silver components from discoloring due to chemical reactions. In the packaging field, food-grade liner paper has non-toxic properties and is widely used for medical device isolation and food protection.

[0003] Before use, liner paper often has different requirements due to different usage needs. To meet these different needs, it is often necessary to spray relevant materials onto the surface of the liner paper to change its usage characteristics and thus meet subsequent usage requirements. For this purpose, spraying equipment is required. However, in actual use, traditional spraying equipment may spray the material onto the outside of the liner paper when dealing with smaller liner paper due to the different sizes of the liner paper. This can affect the spraying process, lead to material waste, and fail to meet the spraying requirements. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable coating device for the surface treatment of backing paper, so as to solve the technical problem that existing spraying equipment cannot accurately control different specifications and sizes during spraying, resulting in waste of spraying materials or failure to meet the requirements of the sprayed surface.

[0026] like Figure 1-4As shown in the figure, an adjustable coating device for surface treatment of backing paper according to an embodiment of the present invention includes a base 1. A first mounting plate 4 is fixedly installed on the rear side of the top of the base 1. Guide rollers 2 are rotatably connected to the right side of the front side of the first mounting plate 4. Two tension adjusting rollers 3 are arranged on the front side of the first mounting plate 4 and to the left of the guide rollers 2. A second mounting plate 5 is fixedly installed on the front side of the first mounting plate 4. A receiving box 6 is fixedly installed on the top of the second mounting plate 5. A coating device 9 is arranged on the left side of the receiving box 6. The first mounting plate 4 is used to install the guide rollers 2 and the tension adjusting rollers 3. The tension adjusting roller 3 is used to stretch the backing paper to be sprayed, so as to avoid wrinkles during spraying and affect the spraying effect. The guide roller 2 is used to guide and transport the backing paper to be sprayed. The second mounting plate 5 is used to install the receiving box 6 and the coating equipment 9. The receiving box 6 is used to hold the raw material to be sprayed. The coating equipment 9 is used to spray the raw material onto the surface of the backing paper. At the same time, the nozzle 905 can be raised and lowered and the spraying width can be switched on and off according to the needs of the backing paper, so as to meet the spraying needs of backing paper of different sizes.

[0027] The coating equipment 9 includes a rectangular mounting tube 902 located below the second mounting plate 5 and three circular tubes 906 fixedly installed at the bottom of the rectangular mounting tube 902. The bottom of the circular tubes 906 is connected to three nozzles 905. Solenoid valves 908 are fixedly installed at the top of the circular tubes 906 and inside the rectangular mounting tube 902. A feed pump 907 is fixedly installed at the top of the second mounting plate 5 and on the left side of the receiving box 6. The rectangular mounting tube 902 is set up to install the circular tubes 906. The circular tubes 906 and the nozzles 905 spray the raw material onto the surface of the backing paper. The solenoid valves 908 are used to control the opening and closing of the circular tubes 906, thereby adjusting the spraying width to meet the requirements of spraying backing paper of different specifications.

[0028] An electric push rod 901 is fixedly installed on the top of the second mounting plate 5. The output end of the electric push rod 901 passes through the second mounting plate 5 and is fixedly connected to the top of the rectangular mounting tube 902. The electric push rod 901 is used to drive the rectangular mounting tube 902 to raise and lower the round tube 906, thereby adjusting the distance between the nozzle 905 and the backing paper. This allows for different atomization spraying effects for raw materials with different concentrations. For raw materials with higher concentrations of spraying agent, the atomization effect is poorer and needs to be increased, so the spraying distance of the raw material needs to be increased to improve the atomization effect. Conversely, the concentration angle reduces the distance between the nozzle 905 and the backing paper.

[0029] The input end of the feed pump 907 is connected to the feed pipe 903, and the end of the feed pipe 903 extends into the interior of the receiving box 6. The feed pipe 903 is provided to pour the raw material inside the receiving box 6 into the feed pump 907 for pressurization to facilitate subsequent injection.

[0030] The output end of the feed pump 907 is connected to the feed pipe 904, and the end of the feed pipe 904 is connected to the top of the round pipe 906. The feed pipe 904 is provided to send the pressurized raw material to the inside of the round pipe 906 and the nozzle 905 to spray the backing paper.

[0031] The top of the container 6 is connected to a filling port 7, and the front of the container 6 is connected to a discharge port 8. The filling port 7 is used to fill the raw materials into the container 6, and the discharge port 8 is used to discharge the unused raw materials from the container 6.

[0032] The first mounting plate 4 has two grooves 12 inside, and a slider 10 is slidably connected inside the groove 12. One side of the slider 10 is fixedly connected to the rear side of the tension adjusting roller 3. The grooves 12 and slider 10 are used to install the tension adjusting roller 3 and can drive the tension adjusting roller 3 to rise and fall to adjust the tension of the paper during conveying.

[0033] A spring 11 is fixedly installed at the bottom of the slider 10. The bottom of the spring 11 is fixedly connected to the bottom of the inner cavity of the slide groove 12. The spring 11 is set to squeeze the slider 10, thereby driving the tension regulating roller 3 to rise, and thus squeezing and regulating the tension of the backing paper.

[0034] In use, the backing paper to be sprayed is turned at the bottom of the guide roller 2 and led out through the top of the tension adjusting roller 3. The raw material to be sprayed is added into the container 6 through the filling port 7. After the filling is completed, the corresponding round pipe 906 is closed by the solenoid valve 908 according to the size of the backing paper to be sprayed. After the adjustment is completed, the backing paper is conveyed by the feeding pump 907 and the feeding pipe 903 to extract the raw material in the container 6 and squeeze it through the conveying pipe 904 to the round pipe 906 and the nozzle 905. The raw material is atomized and sprayed onto the surface of the backing paper through the nozzle 905. After use, the unused raw material in the container 6 is discharged through the discharge port 8 and the cleaning liquid is added into the container 6 through the filling port 7 to clean the feeding pipe 903, the conveying pipe 904, the nozzle 905, the round pipe 906 and the feeding pump 907.

[0035] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
