Description

Technical Field

[0001] This utility model relates to the field of board processing technology, and in particular to a plywood gluing machine with intermittent feeding. Background Technology

[0002] Plywood gluing is a core process in the production of engineered wood products. It involves uniformly applying adhesive to the surface of veneers, bonding multiple layers of veneers firmly under hot pressing to form plywood products with specific mechanical properties and stable structures. The quality of the gluing directly affects the interlayer bond strength, water resistance, environmental performance, and the final product's lifespan. Especially in the crucial pretreatment process before veneer assembly, existing gluing machines are increasingly revealing a series of significant limitations and technical problems in meeting the production needs of plywood for different applications and grades.

[0003] Specifically, existing glue applicators face significant challenges in practical operation, including a single application method, difficulty in achieving precise control, and a high risk of glue waste. Traditional glue applicators often employ continuous roller coating or spraying methods, with the glue rollers or nozzles continuously rotating to fully cover the entire veneer surface. This lack of flexibility in adjusting the coating area and amount according to actual needs prevents adjustments. However, in some applications, such as manufacturing lightweight structural panels, special spliced ​​panels, or customized products requiring pre-reserved glue-free areas, continuous coating across the entire veneer surface is unnecessary. Instead, intermittent, zoned, and precise coating is required. Existing equipment, lacking an effective intermittent control mechanism, necessitates coating the entire veneer, resulting in a large amount of adhesive being unnecessarily applied to areas that will be cut later or do not require bonding. This significantly increases glue consumption costs and, due to excessively thick or improperly distributed glue layers, affects the venting and curing effects during hot pressing, easily leading to defects such as delamination and bubbling, thus reducing the yield. Therefore, to address these shortcomings of existing technologies, we urgently need an innovative plywood glue applicator with intermittent feeding to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a plywood gluing machine with intermittent feeding, which solves the problem of the lack of an effective intermittent control mechanism in the prior art, which requires gluing the entire board and results in a large amount of adhesive being unnecessarily applied to areas that will be cut or do not need to be glued later. This not only significantly increases the cost of adhesive consumption, but also causes problems such as excessively thick or unreasonable distribution of adhesive layers.

[0005] To achieve the above objectives, this utility model provides a plywood gluing machine with intermittent feeding, including a frame, and conveyor rollers rotatably connected to both sides of the inner side of the frame, with a conveyor belt wound and connected between the two conveyor rollers. A drive motor is bolted to one side of the outer wall of the frame, and one end of one of the two conveyor rollers passes through the side wall of the frame and is connected to the output shaft of the drive motor. A rotating tube is rotatably connected to the top side of the conveyor belt, and a connecting rod is rotatably connected to one side of the outer wall of the frame. A half gear is sleeved on one end of the connecting rod, and a gear disk is sleeved on one end of the rotating tube. The half gear and the gear disk are meshed. One end of the connecting rod is connected to one end of one of the two conveyor rollers by a belt. A pump body is bolted to one side of the outer wall of the frame, and the outlet of the pump body is connected to one end of the rotating tube. Soft brushes are fixedly connected to the top and bottom of the rotating tube, and the extension ends of the two soft brushes pass through the side wall of the rotating tube. Scrapers are fixedly connected to the inner wall of the frame on both sides of the bottom of the conveyor belt.

[0006] One end of each of the two conveying rollers is rotatably connected to the inner wall of the frame via a rotating shaft, and the other end of each of the two conveying rollers passes through the side wall of the frame via a bearing sleeve.

[0007] Each of the connecting rods has a pulley fitted onto one end and one end of one of the two conveying rollers, and the two pulleys are connected by a belt winding around each other.

[0008] The conveyor belt has limit frames on both sides of its top, and both sides of the limit frames are fixedly connected to the inner wall of the frame.

[0009] One end of the connecting rod is rotatably connected to the side wall of the frame via a rotating shaft, and both ends of the rotating tube pass through the side wall of the frame via bearing sleeves.

[0010] The outer wall of the frame is fixedly connected to a bearing box, and the inlet of the pump body is connected to the lower part of the bearing box. The outlet of the pump body is connected to a connecting pipe, and a rotary joint is connected to one end of the rotating pipe. The connecting pipe and one side of the rotary joint are connected to each other.

[0011] This utility model discloses a plywood gluing machine with intermittent feeding. By incorporating a conveyor belt driven by a drive motor within the frame, it solves the problems of existing gluing machines, such as a single gluing method, difficulty in achieving precise control, and easy waste of glue. The conveyor belt is supported by two conveyor rollers that operate synchronously, ensuring stable delivery of plywood material and providing a stable operating foundation for subsequent gluing. The drive motor is bolted to the outer wall of the frame, and its output shaft is connected to one of the conveyor rollers, ensuring reliable power transmission. The conveyor roller is also connected to a connecting rod via a belt, allowing the connecting rod to rotate synchronously with the conveyor, thus achieving power diversion. The half-gear at one end of the connecting rod meshes with the gear disk at one end of the rotating tube. Utilizing the intermittent meshing characteristic of the half-gear, continuous rotational motion is converted into periodic start-stop rotation of the gear disk and rotating tube, forming a mechanical intermittent drive mechanism that achieves stable intermittent motion without the need for an additional electrical control system. The two ends of the rotating tube are rotatably connected to the frame and connecting rod via bearings, ensuring structural stability and the ability to withstand a certain load. The pump body is bolted to the outer wall of the frame, and its outlet is connected to the rotating tube, continuously supplying adhesive into the tube. Soft brushes fixed at the top and bottom of the rotating tube extend into the tube, effectively absorbing the adhesive. During rotation, the adhesive is evenly transferred to the plywood surface. Due to the intermittent rotation of the rotating tube, the soft brush contacts the material periodically, thus forming discrete adhesive application areas on the continuously moving plywood, effectively avoiding the problem of full-surface coverage caused by traditional continuous adhesive application. This structure allows for flexible control of the adhesive application interval and frequency by adjusting the number of teeth on the half-gear, the rotation speed of the connecting rod, or the speed of the conveyor belt according to production needs, adapting to the processing requirements of different product specifications. By achieving intermittent adhesive application, the amount of adhesive applied to unnecessary areas is significantly reduced, lowering adhesive consumption costs and improving efficiency. This equipment improves resource utilization efficiency and avoids quality problems such as difficulty in hot-pressing and venting, uneven curing, and delamination caused by excessive glue layer thickness, thereby increasing the yield and overall performance of plywood. Excess glue is confined within the soft brush and rotating tube for recycling, reducing glue dripping and splashing, improving the workshop environment, and reducing equipment pollution and cleaning difficulty. The equipment has a simple structure, is easy to maintain, and operates stably, making it particularly suitable for plywood production scenarios that require zoned glue application, lightweight design, or environmentally friendly low-formaldehyde emissions. It meets the urgent needs of the modern engineered wood products industry for energy conservation, precise control, and flexible production. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figure 1-5 , A plywood gluing machine with intermittent feeding includes a frame 1, and conveyor rollers 3 are rotatably connected to both sides of the inner side of the frame 1, and a conveyor belt 2 is wound and connected between the two conveyor rollers 3. A drive motor 10 is bolted to one side of the outer wall of the frame 1, and one end of one of the two conveyor rollers 3 passes through the side wall of the frame 1 and is connected to the output shaft of the drive motor 10. A rotating tube 7 is rotatably connected to the top side of the conveyor belt 2. A connecting rod 4 is rotatably connected to one side of the outer wall of the frame 1, and a half gear 9 is sleeved on one end of the connecting rod 4. A gear disk 8 is sleeved on one end of the rotating tube 7, wherein the half gear 9 and the gear disk 8 are meshed. One end of the connecting rod 4 is connected to one end of one of the two conveyor rollers 3 by a belt 6. A pump body 14 is bolted to one side of the outer wall of the frame 1, and the outlet of the pump body 14 is connected to one end of the rotating tube 7. Soft brushes 11 are fixedly connected to the top and bottom of the rotating tube 7, wherein the extension ends of the two soft brushes 11 pass through the side wall of the rotating tube 7. Scrapers 17 are fixedly connected to the inner wall of the frame 1 on both sides of the bottom of the conveyor belt 2.

[0021] When using a plywood gluing machine with intermittent feeding, the plywood veneer or substrate to be glued is first placed at the starting end of the conveyor belt 2. The conveyor belt 2 is supported and wound together by two conveyor rollers 3. One end of one conveyor roller 3 passes through the side wall of the frame 1 and is connected to one end of the connecting rod 4 via a belt 6. At the same time, the other end of the conveyor roller 3 is connected to the output shaft of the drive motor 10. The drive motor 10, which is bolted to one side of the outer wall of the frame 1, is started. The drive motor 10 drives the conveyor roller 3 to rotate, thereby driving the conveyor belt 2 to run smoothly and convey the plywood material placed on it horizontally to the gluing station. During the conveying process, the drive motor 10 simultaneously passes through the side wall of the frame 1 to rotate the conveyor roller 3. The conveyor roller 3 and belt 6 drive the connecting rod 4 to rotate. A half-gear 9 is sleeved on the other end of the connecting rod 4. The half-gear 9 meshes with a gear disk 8 fixed to one end of the rotating tube 7. When the connecting rod 4 drives the half-gear 9 to rotate continuously, since the half-gear 9 only meshes with the gear disk 8 in part of its teeth, power is transmitted only halfway through each rotation, while the other half disengages. This allows the gear disk 8 to drive the rotating tube 7 to achieve periodic start-stop intermittent rotation. The other end of the rotating tube 7 is rotatably connected to the other side wall of the frame 1 via a bearing structure to ensure stable rotation. Simultaneously, the pump body 14, bolted to one side of the outer wall of the frame 1, is activated. The outlet of the pump body 14 is connected to the rotating tube 7 via a pipe. One end of the rotating tube 7 is connected to continuously pump adhesive into the rotating tube 7. Soft brushes 11 are fixedly connected to both the top and bottom of the rotating tube 7. The extended ends of the soft brushes 11 penetrate the side wall of the rotating tube 7 and extend into its inner cavity. When the adhesive enters the rotating tube 7, it quickly soaks and fills the tube space, then penetrates into the soft brushes 11 at the top and bottom, keeping the soft brushes 11 fully wet and carrying an appropriate amount of adhesive. As the rotating tube 7 rotates intermittently with the cooperation of the half-gear 9 and the gear disk 8, the soft brushes 11 at the top and bottom alternately swing downwards and contact the surface of the plywood that passes by. When the soft brushes 11 are in the lower position, adhesive is applied to the material surface. They then remain stationary during the rotation interruption, waiting for the next engagement cycle. The rotating tube 7 rotates again to apply glue to subsequent boards. Due to the intermittent rotation of the rotating tube 7, the soft brush 11 applies glue to the plywood in a regular pattern of applying, stopping, and reapplying, forming equally spaced strip or block-shaped glue application areas on the continuously conveyed boards, thus achieving intermittent and zoned precise coating. Through the coordinated work of the drive motor 10, conveyor roller 3, belt 6, connecting rod 4, half gear 9, gear disk 8, rotating tube 7, soft brush 11, and pump body 14, the complete process from material conveying and power transmission to intermittent glue application is completed. After the operation is completed, the drive motor 10 and pump body 14 are turned off, and the residual glue in the soft brush 11 and rotating tube 7 is cleaned to prevent clogging and prepare for the next use.

[0022] Furthermore, one end of each of the two conveyor rollers 3 is rotatably connected to the inner wall of the frame 1 via a rotating shaft, and the other end of each of the two conveyor rollers 3 passes through the side wall of the frame 1 via a bearing sleeve. When the drive motor 10 drives one of the conveyor rollers 3 to rotate, the inner end of the conveyor roller 3 is supported by the rotating shaft, and the outer end rotates out through the bearing sleeve, ensuring its stable rotation and driving the conveyor belt 2. The other conveyor roller 3 is fully supported by the rotating shafts and bearing sleeves at both ends, forming a stable double-end support structure. The bearing sleeve not only allows the conveyor roller 3 to rotate freely, but also provides radial positioning and sealing protection to prevent dust from entering and affecting the rotation accuracy. This structure improves the rotational smoothness and load-bearing capacity of the conveyor roller 3, and reduces vibration and wear. This structure, in conjunction with the conveyor belt 2 and the drive motor 10, achieves the effects of ensuring the stable operation of the conveying system, extending the life of the transmission components, improving the conveying accuracy, and facilitating the assembly of the power end.

[0023] Furthermore, pulleys 5 are fitted onto one end of the connecting rod 4 and one end of one of the two conveying rollers 3, and the two pulleys 5 are connected by a belt 6. The pulleys 5 are fixed to the rotating ends of the connecting rod 4 and the conveying roller 3, and the belt 6 is fitted onto the two pulleys 5 to form a synchronous transmission pair. When the drive motor 10 drives the conveying roller 3 to rotate, the pulley 5 at the end of the conveying roller 3 rotates accordingly, and the power is transmitted to the pulley 5 at the end of the connecting rod 4 through the belt 6, thereby driving the connecting rod 4 to rotate. This structure realizes reliable power transmission and ensures that the connecting rod 4 and the conveying roller 3 keep running synchronously. The cooperation between the pulley 5 and the belt 6 has a buffering and vibration reduction effect, which can absorb part of the impact load and protect the transmission system. This structure, together with the connecting rod 4 and the conveying roller 3, achieves the effects of synchronous power transmission, ensuring transmission stability, reducing noise, and facilitating installation and maintenance.

[0024] Furthermore, limiting frames 12 are provided on both sides of the top of the conveyor belt 2, and both sides of the two limiting frames 12 are fixedly connected to the inner wall of the frame 1. When the plywood is conveyed on the conveyor belt 2, its sides are blocked by the limiting frames 12 to prevent the board from shifting laterally or running off course due to vibration or eccentric force during the conveying process. This structure ensures that the plywood moves steadily along the predetermined trajectory and maintains the same relative position with the glue application component below. The fixed connection method of the limiting frames 12 is structurally sound and not easy to loosen. This structure, together with the conveyor belt 2 and the frame 1, achieves the effects of preventing material conveying deviation, ensuring the accuracy of the glue application position, improving processing consistency, and enhancing the automation stability of the equipment.

[0025] Furthermore, one end of the connecting rod 4 is rotatably connected to the side wall of the frame 1 via a rotating shaft. Both ends of the rotating tube 7 pass through the side wall of the frame 1 via bearing sleeves. One end of the connecting rod 4 obtains a fixed fulcrum through the rotating shaft, achieving stable rotational support. Both ends of the rotating tube 7 are connected to the side wall of the frame 1 via bearing sleeves, forming a double-end support structure, which significantly improves the rotational rigidity and coaxiality of the rotating tube 7, preventing it from deflecting or vibrating due to cantilever force during intermittent rotation. The bearing sleeves provide good radial support and sealing performance, reducing frictional loss and extending service life. This structure provides a stable foundation for the meshing transmission of the half gear 9 and the gear disk 8, ensuring the accuracy and repeatability of intermittent motion. This structure, used in conjunction with the half gear 9, gear disk 8, and soft brush 11, achieves the effects of improving the support stability of rotating components, ensuring accurate and reliable intermittent glue application, reducing operating vibration, and improving the overall durability of the equipment.

[0026] Furthermore, a carrier box 15 is fixedly connected to one side of the outer wall of the frame 1, and the inlet of the pump body 14 is connected to the lower part of the carrier box 15. A connecting pipe 13 is connected to the outlet of the pump body 14. A rotary joint 16 is connected to one end of the rotating pipe 7, and one end of the connecting pipe 13 is connected to one side of the rotary joint 16. The carrier box 15 is used to store adhesive. The pump body 14 draws adhesive from the carrier box 15 and delivers it to the rotary joint 16 through the connecting pipe 13. The rotary joint 16 is installed at the rotating end of the rotating pipe 7, allowing the adhesive to flow continuously and stably into the rotating pipe 7 during intermittent rotation, avoiding interruption of adhesive supply due to pipe entanglement or breakage. This structure realizes a dynamic sealing connection between the static pipe and the rotating component, ensuring the continuity and reliability of the adhesive supply system. The connecting pipe 13 is a flexible or bendable pipe to adapt to the range of motion of the rotary joint 16. This structure, used in conjunction with the pump body 14 and the rotating pipe 7, achieves the effects of continuous and stable adhesive supply, avoiding pipe entanglement, improving the safety of the adhesive supply system, and facilitating maintenance and replacement.

[0027] In summary.

[0028] When using a plywood gluing machine with intermittent feeding, the plywood veneer or substrate to be glued is first placed at the starting end of conveyor belt 2. Conveyor belt 2 is supported and wound together by two conveyor rollers 3. One end of one conveyor roller 3 is rotatably connected to the inner wall of frame 1 via a rotating shaft, and its outer end is supported by a bearing sleeve passing through the side wall of frame 1. The other end of the conveyor roller 3 is connected to the output shaft of drive motor 10, which is bolted to the outer wall of frame 1 to provide power. After starting drive motor 10, its output shaft drives the conveyor roller 3 to rotate, thereby driving conveyor belt 2 to run smoothly and convey the plywood material horizontally to the gluing station. Meanwhile, a pulley 5 is sleeved on the outer end of the conveyor roller 3. The pulley 5 is connected to another pulley 5 at one end of the connecting rod 4 via a belt 6, forming a synchronous transmission pair, so that the connecting rod 4 rotates synchronously with the conveyor roller 3. The other end of the connecting rod 4 is rotatably connected to the side wall of the frame 1 via a rotating shaft to obtain a stable fulcrum. The half gear 9 sleeved at its end meshes with the gear disk 8 fixed at one end of the rotating tube 7. When the connecting rod 4 rotates continuously, the half gear 9 periodically meshes with and disengages from the gear disk 8, transmitting only half a revolution of power in each revolution, so that the gear disk 8 drives the rotating tube 7 to achieve intermittent rotation with alternating start and stop. Both ends of the rotating tube 7 pass through the side wall of the frame 1 through bearing sleeves, forming a... The structure features a double-end support to ensure high rigidity and coaxiality during intermittent rotation, preventing vibration or displacement due to cantilever stress. Simultaneously, the pump body 14 is activated. The pump body 14 is bolted to the outer wall of the frame 1, and its inlet connects to the lower part of a support box 15 fixed to one side of the outer wall of the frame 1. Adhesive is drawn from the support box 15, and its outlet connects to a rotary joint 16 installed at the rotating end of the rotating tube 7 via a connecting pipe 13. The rotary joint 16 allows the adhesive to flow continuously and stably into the rotating tube 7 during intermittent rotation. After entering the rotating tube 7, the adhesive quickly fills the cavity and penetrates into the soft brushes 11 fixed at the top and bottom. The extended ends of the soft brushes 11 penetrate the rotating tube. The sidewall of tube 7 extends into the inner cavity to fully absorb the adhesive and keep it moist. As the rotating tube 7 rotates intermittently, the soft brushes 11 at its top and bottom swing downward alternately and contact the surface of the plywood that it passes. The adhesive application is completed at the moment of contact. Then, it remains stationary during the rotation stop and moves again in the next meshing cycle, thereby forming regularly distributed strip or block adhesive application areas on the continuously moving board, realizing intermittent and zoned precise coating. In order to prevent the material from shifting laterally during the conveying process, the top two sides of the conveyor belt 2 are provided with limiting frames 12 fixed by the inner wall of the frame 1 to constrain the sides of the plywood and ensure that it moves stably along the predetermined trajectory, thus ensuring the accuracy of the adhesive application position.The entire system, through the coordinated operation of components such as drive motor 10, conveyor roller 3, conveyor belt 2, pulley 5, belt 6, connecting rod 4, half gear 9, gear disk 8, rotating tube 7, soft brush 11, pump body 14, bearing box 15, and rotary joint 16, completes the entire process from material conveying, power transmission, intermittent control to precise glue supply. After the operation is completed, drive motor 10 and pump body 14 are turned off, and residual glue in soft brush 11 and rotating tube 7 is cleaned to prevent blockage and prepare for the next use. By installing a conveyor belt 2 driven by a drive motor 10 inside the frame 1, the problems of existing glue applicators, such as a single glue application method, difficulty in achieving precise control, and easy waste of glue, are solved. Two conveyor rollers 3 are connected to the inner wall of the frame 1 via rotating shafts and pass through the side wall of the frame 1 via bearing sleeves, forming a stable double-end support structure. This improves the rotational accuracy and load-bearing capacity of the conveyor rollers 3, reduces vibration and wear during operation, and ensures the smooth operation of the conveyor belt 2. The drive motor 10 is fixed to the outer wall of the frame 1 with bolts, and its output shaft directly drives one of the conveyor rollers 3, ensuring reliable and efficient power transmission. The pulley 5 sleeved at the end of the conveyor roller 3... The belt 6 connects to the pulley 5 at the end of the connecting rod 4, achieving power splitting and ensuring that the connecting rod 4 operates synchronously with the transmission system. The connecting rod 4 is rotatably connected to the side wall of the frame 1 via a rotating shaft, obtaining a stable rotation fulcrum. The half gear 9 at its end meshes with the gear disk 8 at the end of the rotating tube 7. Utilizing the intermittent meshing characteristic of the half gear 9, continuous rotation is converted into the periodic start-stop motion of the rotating tube 7, forming a mechanical intermittent drive mechanism that can achieve stable and reliable intermittent glue application without complex electrical control. The two ends of the rotating tube 7 pass through the side wall of the frame 1 via bearing sleeves, obtaining double-end support, significantly improving its rotational rigidity and operational stability, and avoiding the problems caused by single-sided cantilever. The flexible deformation ensures the repeatability and accuracy of the adhesive application action of the soft brush 11; the pump body 14 is fixed to the outer wall of the frame 1 by bolts, and its inlet is connected to the carrier box 15 to realize the continuous supply of adhesive; the outlet is connected to the rotary joint 16 through the connecting pipe 13. The rotary joint 16 is installed at the rotating end of the rotating pipe 7 to realize the dynamic sealing connection between the stationary pipe and the rotating component, ensuring that the adhesive flows in continuously and stably during the intermittent rotation of the rotating pipe 7, avoiding pipe entanglement or breakage; the soft brush 11 is fixed to the top and bottom of the rotating pipe 7, and its extension end extends into the pipe to draw adhesive. It intermittently applies adhesive to the surface of the plywood as the rotating pipe 7 swings intermittently, forming discrete adhesive application areas. This design effectively avoids the problem of full-surface coverage caused by traditional continuous gluing; the parameters of the half-gear 9 and the conveyor speed can be adjusted according to production needs to flexibly control the gluing interval and frequency to adapt to different product specifications; this structure significantly reduces the amount of adhesive applied in unnecessary areas, lowers the cost of adhesive consumption, and improves resource utilization; it avoids quality problems such as difficulty in hot pressing and venting, uneven curing, and delamination and bubbling caused by excessive adhesive layer, thus improving the yield and product performance; the carrier box 15 centrally stores the adhesive liquid, which is convenient for management and replenishment; the limiting frame 12 is fixed on both sides of the conveyor belt 2 to laterally limit the plywood, prevent deviation, and ensure the consistency of the gluing position;The entire equipment features a compact structure, stable transmission, and convenient maintenance. It is particularly suitable for plywood manufacturing scenarios requiring energy conservation, low formaldehyde emissions, and flexible production. It meets the modern engineered wood products industry's demands for precise control, green manufacturing, and high-efficiency automation. It effectively solves the problems of material waste, quality fluctuations, and poor production flexibility caused by the uninterrupted glue supply of traditional glue applicators, providing technical support for the development of diversified and customized products. It possesses excellent economic and practical value, contributing to the intelligent and sustainable development of the plywood industry.
