Description

Technical Field

[0001] This utility model relates to the field of decorative paper coating technology, specifically a decorative paper coating device. Background Technology

[0002] Decorative paper, with its certain thickness and rigidity, is an essential raw material in many building materials, such as low-pressure and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. In product structures, decorative paper primarily serves to provide decorative patterns and to cover and prevent the underlying adhesive from seeping through. Pre-applying adhesive is required before applying decorative paper.

[0003] As mentioned in Chinese patent application CN202323061536.8, a single-sided gluing device for door panel decorative paper states: "A gluing table is provided above the gluing table, which is a movable gluing part for applying glue to the surface of the decorative paper on the gluing table. The movable gluing part is horizontally arranged, and at both ends of the movable gluing part are adjustment parts for moving the movable gluing part on the surface of the gluing table. The movable gluing part includes a glue dispensing part horizontally arranged above the gluing table. A horizontal sleeve is provided at the top of the glue dispensing part, and a rotating rod is inserted into the sleeve. The side wall of the rotating rod extends to the outside of the sleeve and is connected to a rotating scraper that flips outside the glue dispensing part. The rotating scraper moves back and forth above the gluing table with the movable gluing part and flips to evenly spread the glue squeezed out by the glue dispensing part onto the decorative paper. This solves the problem that the amount of glue applied by the gluing roller cannot be controlled, which easily leads to excessive glue on the surface of the decorative paper or uneven glue thickness on the surface of the decorative paper."

[0004] Through a search of the aforementioned patents and by simulating their use, we found that the technology still has certain shortcomings:

[0005] On the one hand, after the decorative paper is placed on the table, it may move or even deviate in position during the gluing process due to equipment vibration or external factors, as the paper cannot be properly positioned or fixed. When the decorative paper is not in the correct position, it needs to be manually corrected, which affects the normal progress of the gluing work. On the other hand, when applying glue to the decorative paper on the gluing table, only one piece of decorative paper can be glued at a time. When it is time to apply glue to the next piece of decorative paper, it is necessary to wait for the current piece of decorative paper to be glued and removed. This process involves a long waiting period, making it difficult to improve the gluing efficiency of the decorative paper.

[0006] Therefore, in response to the technical problems mentioned above in the existing technology, we have designed a decorative paper coating device with better performance. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a decorative paper coating device, comprising a fixed base, on the top of which are two coating platforms, one close to each other, with positioning strips on the top of both coating platforms. Both coating platforms have cavities within their inner chambers, and suction holes communicating with these cavities are located on the top of each platform. Vacuum pumps are installed on both the front and rear sides of the fixed base, and the air inlets of both vacuum pumps are connected to the cavities of coating platforms through air pipes. Guide grooves are provided on both sides of the top of the fixed base, with guide sliders slidably connected in each groove. Lifting components are located on the top of each guide slider, and a fixed plate is positioned between the tops of the two lifting components. A storage box is fixed to the top of the fixed plate, and a suction pump is installed on the top of the storage box. A coating component communicating with the suction pump is located at the bottom of the fixed plate.

[0009] As a further embodiment of this utility model: the glue application assembly includes a delivery pipe, a discharge pipe and a glue outlet, the discharge pipe is fixed in the inner cavity of the fixing plate, and there are multiple glue outlets that are equidistantly connected to the bottom of the discharge pipe and extend through the fixing plate.

[0010] As a further embodiment of this utility model: two storage boxes are fixed on the top of the fixed plate, and each storage box is equipped with a suction pump. The inlet of the suction pump is connected to the inside of the storage box through a pipe. A guide pipe is connected between the outlets of the two suction pumps. The middle part of the guide pipe is fixedly connected to the conveying pipe. Solenoid valves are installed on both ends of the guide pipe and on the pipe body near each suction pump.

[0011] As a further embodiment of this utility model: a scraping assembly is provided at the bottom of the fixing plate and on both sides of the dispensing head. The scraping assembly includes a connecting plate fixed to the bottom of the fixing plate by screws and a scraping plate fixed to the bottom of the connecting plate. The scraping plate is far away from the dispensing head and both sides of its bottom are designed to be inclined.

[0012] As a further embodiment of this utility model: the lifting assembly includes a fixed block fixed to the top of the guide slider, an electric telescopic rod installed in the inner cavity of the fixed block, and a movable block fixedly connected to the power output shaft of the electric telescopic rod, wherein the top of the movable block is fixedly connected to the bottom of the fixed plate.

[0013] As a further embodiment of this utility model: a servo motor is installed on the front of the fixed base at a position corresponding to one of the guide grooves. The power output shaft of the servo motor passes through the guide groove and is connected to a lead screw. The lead screw is located in one of the guide grooves and is threadedly sleeved with the guide slider in the guide groove. The end of the lead screw away from the servo motor is rotatably connected to the other side of the inner wall of the guide groove. A guide rod is fixed in the other guide groove and is slidably sleeved with the guide slider located in the guide groove.

[0014] As a further embodiment of this utility model: a slot is provided on the side of the first and second glue application tables that are close to each other, and a collection frame is placed between the two slots. Two positioning strips are fixed on the top of the first and second glue application tables and on the side close to the slots. The positioning strips are composed of two long strip blocks forming an L-shaped structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] I. In this application, through the designed fixed base, glue application table one, glue application table two, positioning strip, air suction hole and vacuum pump, the positioning strip can be used to position the decorative paper to ensure the accuracy of the glue application position. In conjunction with multiple air suction holes, the decorative paper is adsorbed and stabilized on glue application table one and glue application table two, ensuring the positional stability of the decorative paper during glue application. This avoids the situation where the decorative paper moves due to external factors or equipment vibration, and also avoids the need for manual correction of the position of the decorative paper. Ultimately, the decorative paper can be stably glued on glue application table one and glue application table two.

[0017] Second, in this application, by designing gluing table one and gluing table two, the decorative paper can be applied to gluing table one and gluing table two respectively. When applying gluing table one to apply decorative paper, the decorative paper can be removed and placed on gluing table two, and vice versa. The gluing table one and gluing table two are used interchangeably, which can avoid the waiting period caused by working on only one gluing table, thereby greatly improving the gluing efficiency of decorative paper.

[0018] Third, in this application, by designing two storage bins on the fixed plate, glue can be supplied to the dispensing head separately. When the glue in one storage bin is used up, the glue in the other storage bin can be used. The two storage bins can be exchanged without affecting each other, avoiding the situation where there is only a single storage bin and glue needs to be added after it is used up, which would cause the equipment to stop. This ensures the normal operation of the equipment and guarantees production efficiency. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-6A decorative paper gluing device includes a fixed base 1. Two gluing platforms 2 and 3, close to each other, are fixed to the top of the fixed base 1. Positioning strips 21 are provided on the top of both gluing platforms 2 and 3. Two mutually distancing positioning strips 21 are fixed to the top of both gluing platforms 2 and 3, near the slot 20. Each positioning strip 21 is composed of two long strips forming an L-shape. The L-shaped positioning strips 21 can quickly position the decorative paper, allowing the edges and corners of the paper to engage between the two positioning strips 21. Cavities 18 are provided inside both gluing platforms 2 and 3. Suction holes 19 communicating with the cavities 18 are provided on the top of both gluing platforms 2 and 3. Vacuum pumps 16 are installed on both the front and rear sides of the base 1. The air inlets of the two vacuum pumps 16 are connected to the cavities 18 of the first coating table 2 and the second coating table 3 through the air pipes 17. After the vacuum pumps 16 are started, they can adsorb and stabilize the decorative paper on the table surface through the suction of the suction hole 19. Guide grooves 5 are opened on both sides of the top of the fixed base 1. Guide sliders 7 are slidably connected in the two guide grooves 5. Lifting components 8 are set on the top of the two guide sliders 7. A fixed plate 9 is set between the tops of the two lifting components 8. A storage box 10 is fixed on the top of the fixed plate 9. A suction pump 11 is installed on the top of the storage box 10. A coating component connected to the suction pump 11 is set at the bottom of the fixed plate 9.

[0029] Please see Figure 1 , Figure 4 and Figure 6 In this embodiment, the glue application assembly includes a delivery pipe 14, an outlet pipe 1401, and an outlet head 1402. The outlet pipe 1401 is fixed in the inner cavity of the fixing plate 9, and there are multiple outlet heads 1402 that are equidistantly connected to the bottom of the outlet pipe 1401 and pass through the fixing plate 9.

[0030] Specifically, the glue delivered from the delivery pipe 14 first enters the outlet pipe 1401. Since there are multiple outlets 1402 and the outlet is flat, it can be squeezed out and slowly falls from the bottom of the outlet 1402.

[0031] Please see Figure 1 In this embodiment, two storage tanks 10 are fixed on the top of the fixing plate 9, and each storage tank 10 is equipped with a suction pump 11. The inlet of the suction pump 11 is connected to the inside of the storage tank 10 through a pipe. A guide pipe 12 is connected between the outlets of the two suction pumps 11. The middle part of the guide pipe 12 is fixedly connected to the delivery pipe 14. Solenoid valves 13 are installed at both ends of the guide pipe 12 and on the pipe body close to each suction pump 11.

[0032] Specifically, the two storage tanks 10 can work independently with the two solenoid valves 13. When one storage tank 10 is working, the other storage tank 10 is in a paused state. The glue application efficiency can be improved by feeding the two storage tanks 10 separately. The function of the solenoid valve 13 is to connect the guide pipe 12 and the delivery pipe 14 after opening, so as to facilitate the flow of glue. The two solenoid valves 13 can control the connection or disconnection of the two suction pumps 11 and the delivery pipe 14 respectively. In order to facilitate the feeding of the storage tanks 10, the storage tanks 10 are also provided with feeding ports, which can be sealed with valves or plugs.

[0033] Please see Figure 1 , Figure 5 and Figure 6 In this embodiment, a scraping assembly 15 is provided at the bottom of the fixing plate 9 and at both sides of the glue dispensing head 1402. The scraping assembly 15 includes a connecting plate 1501 fixed to the bottom of the fixing plate 9 by screws and a scraping plate 1502 fixed to the bottom of the connecting plate 1501. The scraping plate 1502 is far away from the glue dispensing head 1402 and both sides of its bottom are designed to be inclined.

[0034] Specifically, since there are scraper blades 1502 on both sides of the dispensing head 1402, when the dispensing head 1402 moves back and forth above the first and second application tables 2 and 3, the two scraper blades 1502 can spread the glue on the decorative paper on the top of the first and second application tables 2 and 3 respectively. The bottom of the scraper blade 1502 is designed to be inclined, which can apply a certain pushing force to the glue when spreading it, so that the glue is spread more evenly. The connecting plate 1501 is fixed to the fixing plate 9 with screws, which can facilitate the subsequent disassembly of the connecting plate 1501 and the cleaning of the scraper blade 1502. After removal, it can avoid obstructing the dispensing head 1402 and facilitate the cleaning of the dispensing head 1402.

[0035] Please see Figure 1 and Figure 3 In this embodiment, the lifting assembly 8 includes a fixed block 801 fixed to the top of the guide slider 7, an electric telescopic rod 802 installed in the inner cavity of the fixed block 801, and a movable block 803 fixedly connected to the power output shaft of the electric telescopic rod 802. The top of the movable block 803 is fixedly connected to the bottom of the fixed plate 9.

[0036] Specifically, by activating the electric telescopic rod 802, its power output shaft can drive the movable block 803 to rise or fall, thereby driving the fixed plate 9 to rise or fall, thus adjusting the distance between the glue head 1402, the scraper 1502 and the first and second glue application tables 2 and 3, thereby enabling glue application operations on decorative panels of different thicknesses.

[0037] Please see Figure 1 and Figure 3In this embodiment, a servo motor 6 is installed on the front of the fixed base 1 at a position corresponding to one of the guide grooves 5. The power output shaft of the servo motor 6 extends through the guide groove 5 and is connected to a lead screw 601. The lead screw 601 is located in one of the guide grooves 5 and is threadedly sleeved with the guide slider 7 in the guide groove 5. The end of the lead screw 601 away from the servo motor 6 is rotatably connected to the other side of the inner wall of the guide groove 5. A guide rod is fixed in the other guide groove 5 and is slidably sleeved with the guide slider 7 located in the guide groove 5.

[0038] Specifically, after the servo motor 6 starts, it can drive the lead screw 601 to rotate through its power output shaft, thereby driving the guide slider 7 fitted with it to slide in the corresponding guide groove 5. This causes the lifting assembly 8, the fixing plate 9, the storage box 10 and other structures to reciprocate on the fixed base 1, which can cyclically apply glue to the decorative paper on the first glue application table 2 and the second glue application table 3. The other guide groove 5 at the top of the fixed base 1 contains a guide slide rod, which can stabilize the guide slider 7 in the guide groove 5 and ensure the stability of the entire structure during movement.

[0039] Please see Figure 1 and Figure 2 In this embodiment, a slot 20 is provided on the side of the glue application table 2 and the glue application table 3 that are close to each other, and a collection frame 4 is placed between the two slots 20.

[0040] Specifically, a slot 20 is provided between the first glue application table 2 and the second glue application table 3. The slot 20 contains a collection frame 4. When the glue dispensing head 1402 passes between the first glue application table 2 and the second glue application table 3, if there is residual glue on the glue dispensing head 1402, it will fall into the collection frame 4. The collection frame 4 collects the residual glue in a concentrated manner, which is convenient for subsequent recycling.

[0041] When using:

[0042] First, prepare the decorative paper to be coated with glue. Place two pieces of decorative paper on the first glue coating table 2 and the second glue coating table 3 respectively. Use the positioning strips 21 on the first glue coating table 2 and the second glue coating table 3 to position the decorative paper (so that two corners of the decorative paper are engaged between the two positioning strips 21). Then, start the two vacuum pumps 16 and use the suction effect of the suction holes 19 to adsorb and stabilize the decorative paper on the first glue coating table 2 and the second glue coating table 3.

[0043] Then, the servo motor 6 can be started. The power output shaft of the servo motor 6 drives the lead screw 601 to rotate. The rotation of the lead screw 601 causes the guide slider 7 connected to it to slide in the corresponding guide groove 5, thereby driving the lifting assembly 8, the fixed plate 9, and the storage box 10 to move and move to the top of the second coating table 3. Before this, the solenoid valve 13 near the top right of the storage box 10 of the fixed plate 9 can be opened to start the suction pump 11 located on the top right of the fixed plate 9. The suction pump 11 draws out the glue from the storage box 10 on the top right of the fixed plate 9 and delivers it through the guide pipe 12, the conveying pipe 14, and the outlet pipe 1401 into multiple glue outlets 1402. After that, it slowly flows out through the glue outlets 1402 and is coated on the top of the second coating table 3. On the decorative paper, since the glue dispensing head 1402 is driven by the servo motor 6 to move, the glue dispensing head 1402 can evenly apply glue to various positions of the decorative paper when it moves. Since there is a scraper 1502 at the bottom of the fixing plate 9, when the fixing plate 9 moves, the bottom of the scraper 1502 can flatten and spread the glue on the top of the decorative paper more evenly when the glue dispensing head 1402 dispenses glue. As the guide slider 7 continues to move, when the decorative paper on the second glue application table 3 is finished with glue, the suction pump 11 can be turned off to stop sucking glue. The guide slider 7 can bring the glue dispensing head 1402 to the top of the first glue application table 2 and restart the suction pump 11 to complete the glue application operation on the first glue application table 2.

[0044] When the dispensing head 1402 is applying glue on the first glue application table 2, since the decorative paper on the second glue application table 3 has already been glued, the vacuum pump 16 connected to the second glue application table 3 can be turned off, and the glued decorative paper can be removed from the second glue application table 3. Then, a new decorative paper that needs to be glued can be placed on it, and the vacuum pump 16 connected to the second glue application table 3 can be restarted. Conversely, when the dispensing head 1402 is applying glue on the second glue application table 3, the removal and installation of the decorative paper can be completed on the first glue application table 2. This method can avoid the waiting period and improve the glue application efficiency.

[0045] After the glue in the top right storage box 10 of the fixed plate 9 has been used for a period of time, the solenoid valve 13 connected to the top right storage box 10 of the fixed plate 9 can be closed, the solenoid valve 13 connected to the top left storage box 10 of the fixed plate 9 can be opened, the suction pump 11 on the top right storage box 10 of the fixed plate 9 can be closed, and the suction pump 11 on the top left storage box 10 of the fixed plate 9 can be started, so that the glue in the top left storage box 10 of the fixed plate 9 can be transported to the glue outlet 1402. Since the top right storage box 10 of the fixed plate 9 and the suction pump 11 are in a stopped working state, glue can be added to the top right storage box 10 of the fixed plate 9. After the glue in the top left storage box 10 of the fixed plate 9 has been used for a period of time, the top right storage box 10 of the fixed plate 9 can be replaced for operation.

[0046] 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.
