Technical Field
[0001] This utility model relates to the field of negative ion decorative paper production technology, specifically a double-sided impregnation equipment for producing tourmaline negative ion decorative paper. Background Technology
[0002] Tourmaline negative ion decorative paper is a decorative material made by adding the natural mineral tourmaline. Its main function is to release negative ions to purify indoor air. Negative ion decorative paper is a type of decoration material that releases negative ions, effectively purifying indoor air, removing odors and harmful gases, and improving indoor air quality. Negative ions can also enhance human immunity, improve sleep quality, and relieve stress and fatigue.
[0003] The existing equipment has the following problems when in use: After impregnating the decorative paper with glue, the glue is usually scraped on both the top and bottom sides of the decorative paper, causing the glue to accumulate on both sides of the decorative paper. As a result, the sides of the decorative paper are not flat, which affects subsequent processing. Secondly, excess glue will fall back into the glue tank, causing air bubbles to be generated in the glue tank. If the air bubbles are not eliminated in time, they will accumulate and greatly affect the subsequent impregnation effect of the decorative paper, reducing the quality of the glue used. Summary of the Invention
[0004] The purpose of this invention is to provide a double-sided impregnation equipment for producing tourmaline negative ion decorative paper, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sided impregnation equipment for producing tourmaline negative ion decorative paper, comprising a machine body, a glue tank, and a receiving chamber. Inside the machine body, from left to right, are arranged a guide roller A, a conveying roller, and a guide roller B. A glue tank is arranged side-by-side on the bottom side of the machine body. A pressure roller is installed inside the glue tank. A rotating motor is installed at the bottom of the glue tank, and the output end of the rotating motor extends into the glue tank and connects to a stirring rod. A receiving chamber is located on one side of the glue tank. A filter plate is placed on the top of the receiving chamber. A guide plate is installed inside the receiving chamber. A control chamber is installed on the top side of the machine body. A bidirectional lead screw is installed inside the control chamber. A slide block is threaded onto the surface of the bidirectional lead screw. A connecting frame is connected to the bottom of the slide block, and a scraper roller is rotatably connected to the bottom of the connecting frame.
[0006] Preferably, the machine body has conveying ports on both sides, the glue box has heating rods on both sides inside, and the guide plate has an ultrasonic probe.
[0007] By adopting the above technical solution, decorative paper enters and exits the machine body through the conveyor port. The decorative paper enters the machine body and passes sequentially through the upper surface of guide roller A, the lower surface of pressure roller, conveyor roller, and the upper surface of guide rod B before exiting through the conveyor port. The decorative paper enters the glue tank and is impregnated with glue by the pressure roller. A rotating motor drives the stirring rod to rotate, and a heating rod heats the glue solution inside the glue tank, causing air bubbles inside the glue solution to rise, thus preventing glue coagulation and eliminating air bubbles, improving the impregnation effect. Two sets of stirring blades are activated to increase the uniformity of glue solution heating. After impregnation... Decorative paper is conveyed by conveyor rollers. A start-up control motor drives a bidirectional lead screw to rotate. The bidirectional lead screw, in conjunction with a slide block, moves the scraper roller at the bottom, allowing adjustment based on the width of the decorative paper. This ensures the scraper roller contacts both sides of the decorative paper, accelerating the flow of excess adhesive and quickly scraping it away. The excess adhesive falls onto a filter plate in the receiving compartment. The filter plate removes impurities and air bubbles from the adhesive, which is then guided by a guide plate to the inside of the glue tank. An ultrasonic probe is activated to emit high-frequency vibrations, further eliminating air bubbles in the adhesive passing through the guide plate, facilitating subsequent use.
[0008] Preferably, a drain outlet is provided on one side of the receiving chamber, and a scraper is connected to the top of the machine body.
[0009] By adopting the above technical solution, the scraper, together with the bottom guide roller B, can remove excess glue from the decorative paper, so that the glue on the decorative paper maintains an average thickness.
[0010] Preferably, the glue box is equipped with stirring blades inside, and the two sets of stirring blades are located on both sides of the two sets of pressure rollers.
[0011] By adopting the above technical solution, the two sets of stirring blades increase the uniformity of the adhesive solution heating.
[0012] Preferably, the control compartment is provided with a guide rod inside, the slide is slidably connected to the guide rod, the bottom of the control compartment is provided with a slide groove, and the slide is slidably connected to the slide groove.
[0013] By adopting the above technical solution, the slide moves in conjunction with the guide rod, thus improving the stability of the slide's movement.
[0014] Preferably, a control motor is installed on one side of the control compartment, and a bidirectional lead screw is fastened to the output end of the control motor.
[0015] By adopting the above technical solution, the motor is controlled to drive the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw causes the two sets of slides to move relative to each other.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] The motor is started to rotate the stirring rod, and the heating rod heats the glue liquid inside the glue tank, causing the air bubbles inside the glue liquid to rise, thereby preventing the glue liquid from coagulating and eliminating the air bubbles in the glue liquid, thus improving the glue impregnation effect.
[0018] The bidirectional screw, in conjunction with the slide block, drives the bottom scraper roller to move relative to each other, allowing for adjustment according to the width of the decorative paper. The adjustable scraper roller increases practicality. The scraper roller, together with the scraper plate, ensures that the adhesive on the decorative paper is evenly distributed, while quickly removing excess adhesive. The adhesive falls onto the filter plate on the receiving chamber, where it filters out impurities and air bubbles, preventing air bubbles from affecting the adhesive impregnation effect on the decorative paper.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a technical solution: Please refer to Figure 1 , Figure 2 , Figure 3A double-sided impregnation equipment for producing tourmaline negative ion decorative paper includes a machine body 1, a glue tank 4, and a receiving bin 9. Inside the machine body 1, from left to right, are arranged guide rollers A3, conveying rollers 12, and guide rollers B13. The glue tank 4 is arranged side-by-side on the bottom side of the machine body 1. A pressure roller 6 is installed inside the glue tank 4. A rotating motor 8 is installed at the bottom of the glue tank 4, and the output end of the rotating motor 8 extends into the glue tank 4 and connects to a stirring rod 7. Conveying ports 2 are provided on both sides of the machine body 1. Heating rods 21 are installed on both sides of the glue tank 4. Stirring blades 5 are installed inside the glue tank 4. Two sets of stirring blades... The mixing blades 5 are located on both sides of the two sets of pressure rollers 6. The decorative paper enters and exits the machine body 1 through the conveying port 2. After entering the machine body 1, the decorative paper passes through the upper surface of the guide roller A3, the lower surface of the pressure roller 6, the conveying roller 12, and the upper surface of the guide rod B13 in sequence, and then exits through the conveying port 2. The decorative paper enters the glue tank 4 and is impregnated with glue by the pressure roller 6. The rotating motor 8 is started to drive the stirring rod 7 to rotate. The heating rod 21 heats the glue liquid inside the glue tank 4, causing the bubbles inside the glue liquid to rise, thereby preventing the glue liquid from coagulating and eliminating the bubbles in the glue liquid, improving the impregnation effect. The two sets of mixing blades 5 are started to increase the uniformity of glue liquid heating.
[0026] Please see Figure 1 , Figure 2 , Figure 4The glue tank 4 has a receiving chamber 9 on one side, a filter plate 11 on top of the receiving chamber 9, a guide plate 10 inside the receiving chamber 9, and an ultrasonic probe on the guide plate 10. A control chamber 14 is installed on the top side inside the machine body 1, and a bidirectional lead screw 17 is installed inside the control chamber 14. A slide 18 is threaded onto the surface of the bidirectional lead screw 17, a connecting frame 15 is connected to the bottom of the slide 18, and a scraper roller 16 is rotatably connected to the bottom of the connecting frame 15. A drain port is opened on one side of the receiving chamber 9, and a scraper 20 is connected to the top of the machine body 1. The glue-impregnated decorative paper is conveyed by the conveying roller 12, and the guide roller B13 scrapes away excess glue on the lower surface of the decorative paper, while the scraper 20 scrapes away excess glue on the upper surface, thereby homogenizing the glue on both sides of the decorative paper. The control chamber 14... An internal guide rod is provided, and the slide block 18 is slidably connected to the guide rod. A sliding groove is opened at the bottom of the control chamber 14, and the slide block 18 is slidably connected inside the sliding groove. A control motor 19 is installed on one side of the control chamber 14, and a bidirectional lead screw 17 is fastened to the output end of the control motor 19. When the control motor 19 is started, it drives the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17, in conjunction with the slide block 18, drives the scraper roller 16 at the bottom to move relative to each other. This can be adjusted according to the width of the decorative paper, so that the scraper roller 16 contacts both sides of the decorative paper, accelerating the flow of excess glue and quickly scraping away the excess glue. Thus, the excess glue falls onto the filter plate 11 on the receiving chamber 9. The filter plate 11 filters out impurities and air bubbles in the glue and guides it through the guide plate 10 to the inside of the glue box 4, preventing the falling glue from carrying air bubbles into the glue box 4 and reducing the overall quality of the glue in the glue box 4.
[0027] Working principle: Decorative paper enters and exits the machine body 1 through conveyor port 2. Inside the machine body 1, the decorative paper passes sequentially through the upper surface of guide roller A3, the lower surface of pressure roller 6, conveyor roller 12, and the upper surface of guide rod B13 before exiting through conveyor port 2. The decorative paper enters the glue tank 4, where it is impregnated with glue by pressure roller 6. The rotating motor 8 drives the stirring rod 7 to rotate, and the heating rod 21 heats the glue solution inside the glue tank 4, causing air bubbles inside the glue solution to rise, thus preventing glue coagulation and eliminating air bubbles, improving the impregnation effect. Two sets of stirring blades 5 are activated to increase the uniformity of glue heating. After impregnation, the decorative paper is conveyed by conveyor roller 12, and excess glue on the lower surface of the decorative paper is scraped off by guide roller B13. The excess adhesive on the upper surface is scraped away by the scraper 20, thus uniformizing the adhesive on both sides of the decorative paper. The control motor 19 is started to drive the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17, in conjunction with the slide block 18, drives the scraper roller 16 at the bottom to move relative to each other. This can be adjusted according to the width of the decorative paper, so that the scraper roller 16 contacts both sides of the decorative paper, accelerating the flow of excess adhesive and quickly scraping it away. The excess adhesive falls onto the filter plate 11 on the receiving chamber 9. The filter plate 11 filters out impurities and air bubbles in the adhesive and then guides it to the inside of the glue tank 4 through the guide plate 10. The ultrasonic probe is activated to emit high-frequency vibrations, which further eliminates air bubbles in the adhesive that has passed through the guide plate 10, making it easier for subsequent use.
