Description

Technical Field

[0001] This utility model relates to the field of impregnated paper production technology, specifically to a production equipment for highly scratch-resistant impregnated decorative paper. Background Technology

[0002] Impregnated paper is a composite material made from non-woven wood pulp, PE, and plant fibers, impregnated with melamine resin or phenolic resin. It is characterized by high absorbency, good resistance to dissolution, and low particle shedding rate, and is mainly used as a decorative layer in cabinets, wardrobes, laminate flooring, and building formwork. Since impregnated paper is frequently subjected to external friction and scratches in daily use, its scratch resistance is particularly important.

[0003] A Chinese patent, CN222412436U, describes a production equipment for high scratch-resistant impregnated abrasion-resistant paper. It includes: "A spraying box is positioned above one side of the impregnation tank. The spraying box contains a spraying cavity with guide rollers inside; a through-groove is positioned on the spraying box, with a U-shaped mounting frame inside the spraying cavity. A liquid loading box is positioned below the U-shaped mounting frame, and applicator rollers are positioned inside the liquid loading box and at the lower end of the U-shaped mounting frame. A first motor is positioned on one side of the spraying box, and a second motor is positioned on one side of the U-shaped mounting frame. A liquid storage tank and a liquid pump are positioned above the spraying box, and a liquid delivery pipe is positioned between the liquid pump and the applicator rollers. This production equipment first impregnates the base paper in the impregnation tank, applying a thick and evenly distributed layer of glue. Then, the applicator rollers apply the glue to the base paper, forming a wear-resistant decorative layer and improving the production efficiency of impregnated abrasion-resistant paper."

[0004] The aforementioned technology involves applying a material that enhances the paper's abrasion and scratch resistance to the paper using an applicator roller, and then supplying the material into the applicator roller via an infusion tube. While this method achieves the purpose of coating the paper surface, our simulation revealed certain drawbacks: because the applicator roller receives the material through the infusion tube, the liquid discharged from the tube always exits from the same position. This makes it difficult for the liquid to adhere evenly to the surface of the applicator roller, resulting in uneven coating of the liquid on the paper surface and affecting the paper quality. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high scratch-resistant impregnated decorative paper production equipment, comprising a processing box and a loading tank. A liquid pump connected to the loading tank is installed at the top of the processing box. The output end of the liquid pump is connected to a first liquid outlet and a second liquid outlet via a pipe assembly. The outlet ends of both the first and second liquid outlets are bent and penetrate into the inner cavity of the processing box, respectively connected to a first liquid outlet frame and a second liquid outlet frame. A first liquid outlet is located at the bottom of the first liquid outlet frame, and a second liquid outlet is located at the bottom of the second liquid outlet frame. A scraper is fixed to the inner top wall of the processing box near the first liquid outlet frame, and a fixing plate is fixed to the left side of the inner wall of the processing box. A second scraper is fixed to the bottom of the fixing plate near the second liquid outlet frame.

[0007] As a further embodiment of this utility model: the top left side of the processing box has an inlet for easy paper entry, and the bottom right side of the processing box has an outlet for easy paper exit. Two conveying rollers are rotatably connected to the right side and near the top of the processing box, and two conveying rollers are rotatably connected to the left side and near the bottom of the processing box. The paper enters the processing box from the inlet and passes through the two conveying rollers and the two conveying rollers in sequence before exiting from the outlet.

[0008] As a further embodiment of this utility model: the pipeline assembly includes a first delivery pipe and a second delivery pipe. One end of the first delivery pipe is connected to the infusion pump and the other end is connected to the second delivery pipe. The first outlet pipe and the second outlet pipe are respectively connected to one side of the second delivery pipe. A second valve is installed on both the first outlet pipe and the second outlet pipe.

[0009] As a further embodiment of this utility model: the material tank is mounted on the top of the processing box by a bracket, and the bottom of the material tank is connected to the infusion pump through a pipe.

[0010] As a further embodiment of this utility model: the inner cavity of the processing box is rotatably connected to support rollers at the positions below scraper one and scraper two, the bottoms of scraper one and scraper two are both designed as arc structures, and scraper one and scraper two are both designed as inclined.

[0011] As a further embodiment of this utility model: the front and rear sides of the liquid outlet frame one and the liquid outlet frame two are fixed to the inner wall of the processing box by brackets. The height of the liquid outlet frame two inside the processing box is lower than that of the liquid outlet frame one, and the liquid outlet frame one and the liquid outlet frame two are staggered.

[0012] As a further embodiment of this utility model: an electric heating plate is installed on the inner top wall of the processing box and on one side of the scraper, and an electric heating plate is installed on the bottom of the fixing plate and on one side of the scraper.

[0013] As a further embodiment of this utility model: a hot air blower is also installed on the back of the processing box. The output port of the hot air blower is connected to two air ducts through a U-shaped tube. The ends of the two air ducts away from the U-shaped tube penetrate into the interior of the processing box and are supported and fixed by a support plate. An inclined air outlet is connected to one side of each of the two hot air ducts at equal distances.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] I. In this application, through the designed pipe assembly, liquid outlet pipe one, liquid outlet frame one, liquid outlet pipe two, and liquid outlet frame two, the liquid agent can be evenly coated onto the paper through liquid outlet frame one and liquid outlet frame two. After coating, the liquid agent can be spread evenly on the paper again by the oblique scraping of scraper one and scraper two, making the liquid agent on the paper more uniform and facilitating the formation of a protective layer on the surface of the paper, thereby giving the paper a scratch-resistant effect.

[0016] Second, in this application, since the first liquid outlet frame and the second liquid outlet frame are at different heights and are staggered, when coating both sides of the paper with liquid, the paper can be guided by the first and second conveyor rollers to come to the bottom of the first and second liquid outlet frames in sequence, so that the liquid can be coated on both sides of the paper. Moreover, the coating is always carried out from the top of the paper, which ensures the stable adhesion between the liquid and the paper, thereby avoiding the situation where the liquid is coated from the bottom of the paper and drips.

[0017] Third, in this application, by designing electric heating plate one, electric heating plate two and hot air blower and other structures, it is possible to first heat dry the paper after coating it with liquid, and then dry it a second time with hot air. This avoids the situation where the airflow sprays onto the paper directly through hot air drying, causing the liquid on the paper that has not yet dried to fluctuate, or even forming wavy patterns on the paper.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-5 A high scratch-resistant impregnated decorative paper production device includes a processing box 1 and a loading tank 2. A liquid pump 3 connected to the loading tank 2 is installed on the top of the processing box 1. The loading tank 2 is mounted on the top of the processing box 1 via a bracket. The bottom of the loading tank 2 is connected to the liquid pump 3 via a pipe. The output end of the liquid pump 3 is connected to an outlet pipe 5 and an outlet pipe 7 via a pipe assembly 4. The outlet ends of both outlet pipe 5 and outlet pipe 7 are bent and penetrate into the inner cavity of the processing box 1, respectively connected to... The liquid outlet frame 6 and the liquid outlet frame 8 are provided. The bottom of the liquid outlet frame 6 is provided with a liquid outlet 601 and the bottom of the liquid outlet frame 8 is provided with a liquid outlet 2. The liquid outlet 601 and the liquid outlet 2 can evenly discharge the liquid so that the liquid falls evenly on the paper 21 that passes through. The inner top wall of the processing box 1 and near the position of the liquid outlet frame 6 are fixedly provided with a scraper 9. The left side of the inner wall of the processing box 1 is fixedly provided with a fixing plate 14. The bottom of the fixing plate 14 and near the position of the liquid outlet frame 8 are fixed with a scraper 2 10.

[0027] Please see Figure 1 In this embodiment, the top left side of the processing box 1 has an inlet for easy entry of paper 21, and the bottom right side of the processing box 1 has an outlet for easy exit of paper 21. Two conveying rollers 12 are rotatably connected to the right side of the processing box 1 near the top, and two conveying rollers 2 are rotatably connected to the left side of the processing box 1 near the bottom. The paper 21 enters the processing box 1 from the inlet and passes through the two conveying rollers 12 and the two conveying rollers 2 in sequence before exiting from the outlet.

[0028] Specifically, the two conveyor rollers 12 and 2 conveyor rollers 2 can make the paper 21 move in an S-shape inside the processing box 1, and the two conveyor rollers 12 can flip the paper 21 so that the original bottom of the paper 21 becomes the top, which facilitates the liquid coating of the liquid outlet frame 2 8.

[0029] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the pipeline assembly 4 includes a first delivery pipe 401 and a second delivery pipe 402. One end of the first delivery pipe 401 is connected to the infusion pump 3 and the other end is connected to the second delivery pipe 402. The first outlet pipe 5 and the second outlet pipe 7 are respectively connected to one side of the second delivery pipe 402. A second valve 20 is installed on both the first outlet pipe 5 and the second outlet pipe 7.

[0030] Specifically, the infusion pump 3 can transport the liquid inside the filling tank 2 to the pipeline assembly 4, and then sequentially to the first outlet pipe 5 and the second outlet pipe 7. Valves 20 are installed on both the first outlet pipe 5 and the second outlet pipe 7, so that the flow rate of the first outlet pipe 5 and the second outlet pipe 7 can be controlled by the two valves 20 respectively, making the flow rate controllable.

[0031] Please see Figure 1 In this embodiment, the inner cavity of the processing box 1 is rotatably connected with support rollers 11 at the position below scraper 9 and the position below scraper 10. The bottom of scraper 9 and scraper 10 are both designed with arc structure, and scraper 9 and scraper 10 are both designed with inclined shape.

[0032] Specifically, by setting support rollers 11 at the bottom of both scraper 19 and scraper 20, a receiving effect can be formed at the bottom of the paper 21. The cooperation between scraper 19 and scraper 20 and support rollers 11 can better smooth and evenly spread the liquid. The bottom of scraper 19 and scraper 20 are both arc-shaped and designed to be inclined, which can better spread the liquid on the paper 21 and avoid scraping off the liquid on the paper 21.

[0033] Please see Figure 1 and Figure 5 In this embodiment, the front and rear sides of the first liquid outlet frame 6 and the second liquid outlet frame 8 are fixed to the inner wall of the processing box 1 by brackets. The height of the second liquid outlet frame 8 inside the processing box 1 is lower than that of the first liquid outlet frame 6, and the first liquid outlet frame 6 and the second liquid outlet frame 8 are staggered.

[0034] Specifically, the first liquid outlet frame 6 and the second liquid outlet frame 8 can respectively coat the top and bottom surfaces of the paper 21 with liquid, ensuring that the coating is always applied from the top of the paper 21 for better results and avoiding liquid dripping when applied from the bottom.

[0035] Please see Figure 1In this embodiment, an electric heating plate 13 is installed on the inner top wall of the processing box 1 and on the side of scraper 9, and an electric heating plate 15 is installed on the bottom of the fixing plate 14 and on the side of scraper 10.

[0036] Specifically, electric heating plate 13 can dry the liquid that has been smoothed by scraper 9, and electric heating plate 15 can dry the liquid that has been smoothed by scraper 10. Drying them separately will result in better results.

[0037] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, a hot air blower 19 is also installed on the back of the processing box 1. The output port of the hot air blower 19 is connected to two air ducts 17 through a U-shaped tube. The ends of the two air ducts 17 away from the U-shaped tube penetrate into the interior of the processing box 1 and are supported and fixed by a support plate 16. An inclined air outlet 18 is connected to one side of each of the two hot air ducts 17 at equal distances.

[0038] Specifically, after the liquid on the upper and lower surfaces of the paper 21 is initially dried by the electric heating plate 13 and the electric heating plate 15, hot air blown from the air outlet 18 can be directed to the upper and lower surfaces of the paper 21 to achieve secondary drying of the liquid on the paper 21. The air outlet 18 is designed to be inclined, which can improve the diffusion effect of the hot air and achieve better results.

[0039] When using:

[0040] Paper 21 enters through the inlet on one side of the processing box 1 and exits from the outlet on the other side of the processing box 1. Inside the processing box 1, the paper is transported in an S-shape by two conveyor rollers 12 and two conveyor rollers 2.

[0041] The electric heating plate 13 and electric heating plate 15 are started for preheating. The infusion pump 3 is started to transport the anti-scratch agent or wear-resistant agent inside the loading tank 2 through the conveying pipe 401 and conveying pipe 402 to the liquid outlet pipe 5 and liquid outlet pipe 7. The liquid outlet pipe 5 transports the liquid to the liquid outlet frame 6, and the liquid outlet pipe 7 transports the liquid to the liquid outlet frame 8. When the paper 21 passes the bottom of the liquid outlet frame 6 (at this time, the top surface of the paper 21 is originally facing up), the liquid is discharged through the liquid outlet 601 at the bottom of the liquid outlet frame 6 and coated on the paper 21. Then it passes the bottom of the scraper 9. The arc at the bottom of the scraper 9 scrapes and spreads the liquid on the paper 21 a second time. After passing the bottom of the electric heating plate 13, the first drying effect is achieved. When the paper 21 is at the bottom of the liquid outlet frame 8, it is guided by the two conveying rollers 12. The top side of paper 21 comes to the bottom, and the bottom side of paper 21 comes to the top. When passing the bottom of the liquid outlet frame 28, the liquid is discharged through the liquid outlet 2 at the bottom of the liquid outlet frame 28 and coated on paper 21. Then it passes the bottom of scraper 210. The arc at the bottom of scraper 210 scrapes and spreads the liquid on paper 21 a second time. After passing the bottom of electric heating plate 25, the first drying effect is achieved. After the liquid is coated on both sides of paper 21, it is discharged from the outlet by the guiding action of two conveying rollers 2. Before discharge, the hot air blower 19 can deliver hot air to two air pipes 17. The two air pipes 17 blow air to both sides of paper 21 in an inclined manner through multiple air outlets 18, thereby achieving secondary drying of the liquid on paper 21, which can improve the drying effect of the liquid and improve the quality of paper.

[0042] It should be noted that the loading tank 2 can be filled with anti-scratch agent or abrasion-resistant liquid. When the paper 21 is coated with anti-scratch agent or abrasion-resistant liquid inside the processing box 1, it can ensure that the paper 21 has improved anti-scratch or abrasion resistance compared to the uncoated paper, so that the impregnated decorative paper produced by this equipment has higher anti-scratch or abrasion resistance.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
