Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of equipment for wood panel processing, and more specifically, to a high-efficiency roll gluing and pressing machine for wood panels. Background Technology

[0002] In the wood-based panel processing industry, roller gluing and pressing is a crucial step in achieving panel lamination and veneer processes, and its efficiency directly impacts production line capacity and enterprise economic benefits. Traditional plate-pressing roller gluing and pressing equipment operates in an intermittent mode, exhibiting significant defects in panel conveying, gluing, and pressing processes, making it difficult to meet the demands of modern industrial production for efficient and continuous operation.

[0003] The long interruptions in continuous processing with traditional equipment stem from the limitations of its mechanical structure. The lifting and positioning of the pressure plates rely on mechanical transmission, resulting in slow response times. Furthermore, manual or mechanical assistance is required to remove the material after each pressing, further extending the production cycle. For example, in the process of multilayer board lamination, the machine must be stopped after each pressing to clean residual adhesive from the pressure plate surface; otherwise, the bonding accuracy of subsequent boards will be affected, impacting the continuity of the production line. For companies with large order volumes and tight delivery schedules, this intermittent production mode can lead to delivery delays, affecting market competitiveness.

[0004] With the rapid development of industries such as customized furniture and construction formwork, the market demand for wood-based panels continues to grow, placing higher demands on processing precision and production efficiency. The inefficiency of traditional sheet-pressing glue-bonding machines has become a bottleneck restricting industry development. Developing a high-efficiency glue-bonding machine capable of continuous operation and reduced downtime is urgently needed. This is crucial for improving production line automation, reducing labor costs, and meeting the delivery needs of large-scale orders, while also aligning with the modern manufacturing industry's trend towards intelligent and efficient transformation. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a high-efficiency roll gluing and pressing machine for wood panels, which solves the technical problems in the prior art where the lifting and positioning of the pressing plate depends on mechanical transmission, the response speed is slow, and manual or mechanical assistance is required to unload the material after each pressing, which further prolongs the production cycle.

[0006] According to one aspect, at least one embodiment of this disclosure provides a high-efficiency roll bonding machine for wood panels, comprising:

[0007] The equipment frame, the glue storage box, and several support rollers are provided. The glue storage box is installed on the side surface of the equipment frame, and the support rollers are all rotatably connected inside the equipment frame.

[0008] The equipment includes a lower roller, a coating roller, and a coating assembly. The lower roller and the coating roller are rotatably connected inside the equipment frame, and the coating assembly is mounted on the equipment frame.

[0009] A conveying and pressing assembly is disposed inside the equipment frame;

[0010] The adhesive coating assembly includes an adhesive coating pipe, which is disposed inside the equipment frame. A liquid pump is disposed on the side surface of the equipment frame. The liquid pump is connected to the adhesive storage tank and the adhesive coating pipe respectively. The bottom surface of the adhesive coating pipe has a plurality of adhesive outlets.

[0011] As a further technical solution, a scraper is provided at the bottom of the adhesive coating pipe, and a first gear is provided at one end of both the lower roller and the adhesive coating roller. The first gears mesh with each other, and the lower roller is rotated by a motor.

[0012] As a further technical solution, the conveying and pressing assembly includes several upper rollers, all of which are rotatably connected inside the equipment frame. A pair of guide rollers are rotatably connected inside the equipment frame, and a pair of guide plates are fixed inside the equipment frame.

[0013] As a further technical solution, the guide plate is located between the guide roller and one of the upper rollers. Two sets of push rollers are rotatably connected inside the equipment frame. Each set of push rollers is a pair. One end of one set of push rollers is provided with a second gear. The push roller at the lower end is controlled to rotate by a motor.

[0014] As a further technical solution, a telescopic cylinder is provided at the top of the equipment frame, and a positioning plate is provided at the output end of the telescopic cylinder. The positioning plate is located between the two sets of push rollers, and a pair of inner plates are provided inside the equipment frame.

[0015] As a further technical solution, the inner plate is movably fitted with several movable rods, and a pressing plate is provided at the lower end of the movable rods. Several springs are connected between the pressing plate and the inner plate.

[0016] As a further technical solution, the surface of the pressing plate is a smooth surface with low friction.

[0017] As a further technical solution, the pair of guide plates are fixedly connected at an inclined angle, and one end of the guide plate at the upper end is bent upwards for transition.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. The beneficial effects of the coating component in this disclosure are that the design of the liquid pump and coating pipeline realizes the automated delivery and uniform coating of glue, the distribution of glue outlets ensures that the glue drips evenly on the surface of the coating roller, and the scraper further smooths the glue layer, avoiding the unevenness problem of traditional manual glue application. The first gear transmission makes the coating roller and the lower roller rotate synchronously, ensuring that the glue application speed matches the board conveying speed, and realizing continuous glue application operation.

[0020] 2. The beneficial effects of the conveying and pressing assembly in this disclosure are that the two sets of pushing rollers achieve synchronous transmission through the second gear, ensuring that the two plates are conveyed at the same speed, avoiding misalignment or wrinkles caused by speed difference. The combination of telescopic cylinder and positioning plate can complete the lateral positioning of the plate instantly, which improves efficiency compared with traditional mechanical positioning. The pressing plate provides elastic pressure through spring, which can adapt to plates of different thicknesses, ensuring tight pressing without damaging the plates. The smooth surface design reduces the resistance of plate conveying. Combined with the guidance of the inclined guide plate, the plates can pass through the pressing area continuously, realizing the seamless connection of the entire process of "glue application-conveying-pressing", which completely solves the drawbacks of intermittent operation of traditional equipment.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-4As shown, it illustrates a high-efficiency roll bonding machine for wood panels according to an embodiment of the present disclosure, comprising:

[0034] The equipment frame 1, the glue storage box 2, and several support rollers 3 are provided. The glue storage box 2 is installed on the side surface of the equipment frame 1, and the support rollers 3 are all rotatably connected inside the equipment frame 1.

[0035] The lower roller 4, the glue-applying roller 5, and the glue-coating assembly 6 are rotatably connected inside the equipment frame 1, and the glue-coating assembly 6 is disposed on the equipment frame 1.

[0036] A conveying and pressing assembly 7 is disposed inside the equipment frame 1;

[0037] The adhesive coating assembly 6 includes an adhesive coating pipe 6-1, which is disposed inside the equipment frame 1. A liquid pump 6-2 is disposed on the side surface of the equipment frame 1. The liquid pump 6-2 is connected to the adhesive storage tank 2 and the adhesive coating pipe 6-1 respectively. The bottom surface of the adhesive coating pipe 6-1 has a plurality of adhesive outlets 6-3. A scraper 6-4 is disposed at the bottom of the adhesive coating pipe 6-1. A first gear 6-5 is disposed at one end of both the lower roller 4 and the adhesive coating roller 5. The first gears 6-5 mesh with each other. The lower roller 4 is rotated by a motor.

[0038] In some examples, during the wood panel gluing and pressing operation, a gluing component 6 is designed to achieve uniform coverage of the glue on the surface of the gluing roller 5 and to apply it to the surface of the board. This component is centered around a gluing pipe 6-1 located inside the equipment frame 1. A liquid pump 6-2 on the side surface of the equipment frame 1 delivers the glue from the glue storage tank 2 to the gluing pipe 6-1. The glue drips evenly onto the surface of the gluing roller 5 through several glue outlets 6-3 on the bottom of the pipe. A scraper 6-4 at the bottom of the gluing pipe 6-1 can scrape the glue accumulated on the surface of the gluing roller 5 to ensure that the glue thickness is uniform. The lower roller 4 meshes with the first gear 6-5 located at one end of the gluing roller 5. When the lower roller 4 is driven to rotate by a motor, it drives the gluing roller 5 to rotate synchronously through gear transmission, so that the glue forms a continuous and uniform glue layer on the surface of the gluing roller 5, providing a reliable foundation for subsequent gluing of the board.

[0039] Through the coordinated operation of components such as the adhesive coating pipe 6-1, liquid pump 6-2, adhesive outlet 6-3, scraper 6-4, first gear 6-5, and motor, the adhesive coating assembly 6 achieves the function of uniformly covering the surface of the adhesive coating roller 5 with adhesive.

[0040] like Figures 1-4As shown in the figure, the conveying and pressing assembly 7 in this embodiment includes several upper rollers 7-1, all of which are rotatably connected inside the equipment frame 1. A pair of guide rollers 7-2 are rotatably connected inside the equipment frame 1. A pair of guide plates 7-3 are fixed inside the equipment frame 1, and the guide plates 7-3 are located between the guide rollers 7-2 and one of the upper rollers 7-1. Two sets of push rollers 7-4 are rotatably connected inside the equipment frame 1, each set of push rollers 7-4 being a pair. One end of one set of push rollers 7-4 is provided with a second gear 7-. 5. The push roller 7-4 located at the lower end is rotated by a motor. A telescopic cylinder 7-6 is provided at the top of the equipment frame 1. A positioning plate 7-7 is provided at the output end of the telescopic cylinder 7-6. The positioning plate 7-7 is located between the two sets of push rollers 7-4. A pair of inner plates 7-8 are provided inside the equipment frame 1. Several movable rods 7-9 are movably connected in the inner plates 7-8. A pressing plate 7-10 is provided at the lower end of the movable rods 7-9. Several springs 7-11 are connected between the pressing plate 7-10 and the inner plates 7-8.

[0041] In some examples, to achieve synchronous conveying, positioning alignment, and pressing of the boards to be bonded, a conveying and pressing assembly 7 is designed. This assembly includes several upper rollers 7-1 rotatably connected inside the equipment frame 1, which, together with support rollers 3 and lower rollers 4, form a board conveying channel. A pair of guide rollers 7-2 and guide plates 7-3 cooperate to guide the boards smoothly into the conveying path. Two sets of push rollers 7-4 (one pair per set) are used to convey two boards to be bonded respectively. The push rollers 7-4 can achieve preliminary pressing. One set of push rollers 7-4 is driven by a motor. The lower roller rotates, and the two sets of push rollers 7-4 rotate synchronously through the second gear 7-5, ensuring that the plates are conveyed synchronously. The telescopic cylinder 7-6 at the top of the equipment frame 1 outputs a positioning plate 7-7, which can descend when the plates are conveyed to the designated position to perform lateral positioning of the two plates and avoid misalignment. Several movable rods 7-9 in the inner plate 7-8 are connected to the lower pressing plate 7-10 through springs 7-11 to the inner plate 7-8, providing elastic pressure when the plates are pressed, ensuring that the two plates are tightly attached and achieving a further pressing effect.

[0042] Through the coordinated operation of components such as upper roller 7-1, guide roller 7-2, guide plate 7-3, push roller 7-4, second gear 7-5, telescopic cylinder 7-6, positioning plate 7-7, inner plate 7-8, movable rod 7-9, pressing plate 7-10, and spring 7-11, the conveying and pressing assembly 7 achieves the function of simultaneously conveying and aligning two plates to be bonded, thereby improving the pressing accuracy and efficiency.

[0043] For example, such as Figure 3 As shown, the surface of the pressing plate 7-10 is a smooth surface with low friction.

[0044] In some examples, a smooth surface can reduce friction as the sheet moves through the laminating plate between 7 and 10, making the sheet move more smoothly and improving the lamination effect.

[0045] For example, such as Figure 3 As shown, the pair of guide plates 7-3 are fixedly connected at an inclined angle, and one end of the guide plate 7-3 at the upper end is bent upwards for transition.

[0046] In some examples, the tilt angle allows the board to enter accurately, and the tilt angle is low enough that it will not bend or break the board.

[0047] In actual use: The motor drives the lower roller 4 to rotate, which in turn drives the glue-applying roller 5 to rotate synchronously via the first gear 6-5. The liquid pump 6-2 delivers the glue from the glue storage tank 2 to the glue-applying pipe 6-1, and the glue drips evenly onto the surface of the glue-applying roller 5 through the glue outlet 6-3. The scraper 6-4 smooths the glue to form a uniform glue layer. The board to be glued is then conveyed by the support roller 3 between the glue-applying roller 5 and the lower roller 4 to complete the glue application. Subsequently, the two sets of push rollers 7-4 rotate synchronously under the drive of the motor, pressing the glued board with another board 7 to be pressed together. -10 material is fed to the pressing area guided by guide roller 7-2 and guide plate 7-3 respectively. Telescopic cylinder 7-6 drives positioning plate 7-7 to descend and perform lateral positioning of the material to ensure alignment. At this time, pressing plate 7-10 applies elastic pressure to the material under the action of spring 7-11. Upper roller 7-1 and lower roller 4 cooperate to make the material pass through the pressing area to complete the bonding. The smooth surface of pressing plate 7-10 reduces frictional resistance. Inclined guide plate 7-3 guides the material to enter smoothly. The whole process is continuous and does not require intermittent shutdown.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
