Description

Technical Field

[0001] This invention relates to the field of wood processing technology, specifically to an integrated sanding and gluing machine and process for processing flame-retardant and waterproof wood veneer. Background Technology

[0002] Wood veneer, a common material for decorative surfaces of wooden furniture, is made through rotary cutting or slicing. It is a type of wood veneer material with straight grain, fine texture, light weight, strong luster, soft hardness, low strength, and moderate shrinkage. Due to these characteristics, it is widely used in the field of furniture decoration. For wood veneer blanks, two key processes, sanding and gluing, are required before they can be used. The core purpose of sanding is to remove the rough structure on the surface of the wood veneer, so that the surface of the wood veneer is smooth and flat, which meets the requirements of furniture decoration for surface texture. The gluing process is to apply a flame-retardant and waterproof glue to the surface of the wood veneer, so as to give the wood veneer flame-retardant and waterproof properties, thereby extending the service life of the wood veneer and expanding its application scenarios. However, in the veneer polishing process, because the veneer itself is relatively thin, if impurities (such as sawdust, grit, etc.) attached to the veneer surface are not removed in advance before participating in the polishing process, these impurities will scratch the veneer surface under the squeezing action of the polishing roller, causing the veneer to be scrapped and resulting in a large amount of material waste. During the repeated friction between the polishing roller and the veneer, the debris generated by the veneer polishing is easy to stick to the surface of the polishing roller. These debris will fill the depression structure on the surface of the polishing roller, resulting in a significant decrease in the roughness of the polishing roller, which in turn makes the subsequent polishing effect of the veneer worse and makes it difficult to guarantee the polishing quality. In the existing processing flow, the sanding process and the gluing process are independent of each other. The veneer after polishing cannot directly enter the gluing process and must go through unnecessary intermediate links such as transfer and temporary storage, which not only prolongs the veneer forming cycle, but also reduces the overall processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of existing methods that fail to remove impurities before polishing, which easily scratch the veneer, gradually reduce the polishing effect, and result in low veneer forming efficiency.

[0004] The present invention achieves the above-mentioned objectives through the following technical solution: a sanding and gluing integrated machine for processing flame-retardant and waterproof wood veneer, comprising a workbench and a conveyor. The conveyor is installed on the upper surface of the workbench and transports the wood veneer from left to right. A frame is installed in the middle of the upper surface of the workbench. A ventilation mechanism, a cleaning mechanism, and a sanding mechanism are installed sequentially from top to bottom inside the frame. A dust extraction fan is installed on the upper surface of the frame. The air inlet of the dust extraction fan is connected to the top of the ventilation mechanism through an air pipe. Under the suction of the dust extraction fan, a negative pressure state is formed inside the ventilation mechanism. The cleaning mechanism can not only remove impurities from the wood veneer but also clean the sanding mechanism. A gluing mechanism and a tray are installed at the right end of the workbench, and the tray is located at the bottom of the gluing mechanism. The ventilation mechanism includes a main pipe installed at the center of the top of the frame, a wind box installed at the bottom of the main pipe, branch pipes installed at both ends of the lower surface of the wind box, a baffle installed in the middle of the inner wall of the branch pipe, and a number of air holes equidistantly opened along the circumference on the lower surface of the baffle. It has two channels, enabling alternating suction of the dust removal and cleaning components; The cleaning mechanism includes a lifting component, a dust removal component, and a cleaning component. The lifting component is installed at the top of the inner cavity of the frame, and the dust removal component and the cleaning component are respectively installed at the left and right ends of the bottom of the lifting component. The lifting component controls the dust removal component and the cleaning component to rise and fall alternately.

[0005] Specifically, the lifting assembly includes a first bracket installed at the top of the inner cavity of the frame. The first bracket has two first guide rods vertically inserted into the left and right sides of its upper surface. The two first guide rods fix the dust removal assembly and the cleaning assembly respectively. A first motor is installed at the bottom of the first bracket. A gear is installed at the output end of the first motor. The gear has racks meshing with the left and right sides of its outer wall. When the first motor drives the gear to rotate clockwise or counterclockwise, the two racks can move in opposite directions, alternating between rising and falling. By using gear and rack transmission, the dust removal component and the cleaning component work alternately, thus achieving the switching of operation modes.

[0006] Specifically, the dust removal assembly includes an air knife installed at the bottom of the first guide rod on the left side. The air knife is installed on the right side with a rack. The air knife is used to suck up impurities from the surface of the wood veneer. A first connecting pipe is vertically installed at the center of the top of the air knife and is inserted into the inner cavity of the branch pipe. A first sealing ring is installed at the top of the first connecting pipe. When the first sealing ring contacts the baffle, it closes the air hole.

[0007] Specifically, the cleaning assembly includes a second bracket installed at the bottom of the first guide rod on the right side, with the second bracket mounted to a rack on its left side. A second connecting pipe is vertically installed at the center of the top of the second bracket and inserted into the inner cavity of the branch pipe. A second sealing ring is installed at the top of the second connecting pipe. The second sealing ring moves upward to contact the baffle, thus closing the air vent. Second guide rods are inserted into the bottom of both the front and rear sides of the second bracket. An air duct is installed inside the second guide rod, and the center of the upper surface of the air duct is connected to the bottom of the second connecting pipe via an air duct. Several brushes and nozzles are alternately installed on the lower surface of the air duct from front to back. When the brushes move, they brush and polish the polishing mechanism, loosening the impurities on the polishing mechanism. The impurities are then sucked away by the nozzles. A drive unit is installed at the top of the front of the second bracket, and a roller is installed at the top of the air duct. The drive unit and the roller work together to drive the air duct to swing back and forth. The air duct swings back and forth by cooperating with the guide groove and rollers. The purpose is to have the brush clean the polishing roller and the suction nozzle suck up the wood chips on the surface of the polishing roller to prevent the polishing roller's polishing ability from decreasing.

[0008] Specifically, the drive unit includes a second motor mounted on the top front of the second bracket, a rotating drum mounted on the output end of the second motor, a guide groove being provided on the outer wall of the rotating drum, and a roller being inserted into the inner cavity of the guide groove.

[0009] Specifically, the guide grooves are distributed in a wave-like pattern on the outer wall of the rotating cylinder.

[0010] Specifically, the polishing mechanism includes a polishing frame installed at the bottom of the inner side of the frame, a third motor installed at the rear of the polishing frame, and a polishing roller installed at the output end of the third motor. The third motor drives the polishing roller to rotate, thereby polishing the wood veneer.

[0011] Specifically, the glue application mechanism includes a frame installed on the right end of the workbench. A drive roller and a glue application roller are mounted from left to right on the left side of the inner side of the frame via bearings. A gearbox is installed on the left side of the front of the frame, driving the drive roller and the glue application roller to rotate in opposite directions, conveying the wood veneer from top to bottom. A fourth motor is installed on the front of the gearbox to drive its rotation. A guide plate is installed on the inner side of the frame, and the guide plate is inclined and distributed at the top between the drive roller and the glue application roller, changing the direction of the wood veneer's movement. A glue tank is installed on the inner side of the frame, through which glue is applied to the glue application roller. A detachable scraper is installed on the top of the glue tank, used to scrape off excess glue from the surface of the glue application roller, allowing the glue application roller to evenly apply glue to the wood veneer. Polishing and adhesive application are integrated, improving processing efficiency.

[0012] A processing technology for an integrated sanding and gluing machine for processing flame-retardant and waterproof wood veneer includes the following steps: Step 1: The wood veneer moves from left to right along the conveyor. The third motor drives the polishing roller to rotate. The polishing roller grinds the wood veneer and polishes it. A vacuum cleaner is installed between the frame and the glue application mechanism to suck up the wood chips on the surface of the polished wood veneer. Step 2: When the wood veneer touches the guide plate, the inclined surface of the guide plate acts as a guide, allowing the wood veneer to move between the drive roller and the glue roller. Under the transmission of the gearbox, the drive roller and the glue roller rotate in opposite directions, so that the wood veneer is conveyed from top to bottom. Under the obstruction of the scraper, the glue is evenly distributed on the glue roller, allowing the glue roller to evenly apply the glue to the surface of the wood veneer. The support plate supports the wood veneer after the glue is applied. Step 3: Before polishing, the first motor drives the gear to rotate clockwise or counterclockwise. Under the gear and rack transmission, the dust removal component and the cleaning component alternately rise and fall to adjust the operation mode. Step 4: When the dust removal component descends, the first connecting pipe moves away from the branch pipe, the air hole opens, and the air knife sucks away impurities on the surface of the wood veneer to prevent hard particle impurities from rolling and pressing the wood veneer when the polishing roller is sanding it, thus avoiding scratches or damage to the wood veneer. Step 5: As the cleaning component descends, the second connecting pipe moves away from the branch pipe, the brush contacts the polishing roller, and the second motor drives the rotating drum to rotate. The inclined surfaces of the guide groove in different directions squeeze the roller, causing the air duct to swing back and forth. This allows the brush to move the wood veneer debris attached to the surface of the polishing roller, loosening the debris. The impurities are then sucked away through the suction nozzle, thus cleaning the polishing roller and maintaining its original roughness to prevent the wood veneer polishing from being obstructed.

[0013] The beneficial effects of this invention are: 1. This invention utilizes a first motor to drive a gear to rotate clockwise or counterclockwise. By leveraging the meshing transmission characteristics of the gear and rack, the dust removal component and the cleaning component are driven to alternately rise and fall in opposite directions. Simultaneously, through the cooperation of the branch pipes with the first connecting pipe and the second connecting pipe, the flow of negative pressure airflow is precisely controlled, thereby enabling rapid switching between the two operating modes, significantly reducing equipment downtime, and significantly improving the overall equipment utilization rate.

[0014] 2. This invention utilizes the air knife in the dust removal component to efficiently remove hard particles adhering to the surface of the wood veneer under the negative pressure generated by the dust extraction fan. This prevents such impurities from causing scratches, cracks, or other damage to the surface of the wood veneer during the subsequent polishing process due to the pressure of the polishing roller. It also prevents impurities from wearing down the surface structure of the polishing roller, thereby reducing material waste caused by discarded wood veneer, extending the service life of the polishing roller, and reducing equipment maintenance costs.

[0015] 3. This invention drives the rotating drum to rotate via a second motor. Utilizing the wavy guide groove on the outer wall of the rotating drum in conjunction with the roller at the top of the air duct, the air duct is driven to move back and forth along the second guide rod. The brush at the bottom of the air duct swings with the air duct, efficiently cleaning and loosening stubborn debris on the surface of the polishing roller. Simultaneously, the loosened debris is sucked away by the suction nozzle, achieving deep cleaning of the polishing roller. This effectively maintains the original roughness of the polishing roller, prevents a decrease in its polishing ability, ensures the consistency and stability of the polishing effect of each subsequent batch of wood veneer, and improves the pass rate of wood veneer polishing quality.

[0016] 4. This invention uses an inclined guide plate to precisely change the movement direction of the polished wood veneer, allowing it to smoothly enter between the transmission roller and the glue-applying roller. Driven by the gearbox, the transmission roller and the glue-applying roller rotate in opposite directions to achieve stable conveying of the wood veneer. At the same time, with the cooperation of the scraper, the glue-applying roller can evenly apply flame-retardant and waterproof glue to the surface of the wood veneer, directly completing the glue-applying process. This integrates the traditionally separate sanding and glue-applying processes into a continuous flow, eliminating unnecessary intermediate steps such as wood veneer transfer and temporary storage. This not only significantly shortens the wood veneer forming cycle but also reduces manual intervention, significantly improving overall processing efficiency. In addition, the uniformity of glue application also ensures the stability of the flame-retardant and waterproof performance of the wood veneer. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of the present invention easier to understand, the preferred embodiments of the present invention are further described below in conjunction with specific embodiments and accompanying drawings.

[0020] Please see Figure 1-10 This invention provides an integrated sanding and gluing machine for processing flame-retardant and waterproof wood veneer, including a workbench 1 and a conveyor 2. The conveyor 2 is installed on the upper surface of the workbench 1 and is used to transport the wood veneer from left to right. A frame 3 is installed in the middle of the upper surface of the workbench 1. The inner cavity of the frame 3 is installed with a ventilation mechanism 4, a cleaning mechanism 6 and a sanding mechanism 7 from top to bottom. A dust extraction fan 5 is installed on the upper surface of the frame 3. The air inlet of the dust extraction fan 5 is connected to the top of the ventilation mechanism 4 through an air pipe. Under the suction of the dust extraction fan 5, a negative pressure is formed in the ventilation mechanism 4. The cleaning mechanism 6 can not only remove impurities from the wood veneer, but also clean the sanding mechanism 7. A gluing mechanism 8 and a support plate 9 are installed on the right end of the workbench 1. The support plate 9 is located at the bottom of the gluing mechanism 8 and is tilted downward to support the wood veneer. The ventilation mechanism 4 includes a main pipe 41 installed at the center of the top of the frame 3. The main pipe 41 is connected to the dust collector 5 through an air pipe. A wind box 42 is installed at the bottom of the main pipe 41. The suction of the dust collector 5 creates a negative pressure in the wind box 42. Branch pipes 43 are installed at both the left and right ends of the lower surface of the wind box 42. A baffle 44 is installed in the middle of the inner wall of the branch pipe 43. Several air holes 45 are equidistantly opened along the circumference on the lower surface of the baffle 44. The main pipe 41 can be connected to the impurity removal mechanism 6 through the air holes 45. The cleaning mechanism 6 includes a lifting component 61, a dust removal component 62, and a cleaning component 63. The lifting component 61 is installed at the top of the inner cavity of the frame 3. The dust removal component 62 and the cleaning component 63 are respectively installed at the left and right ends of the bottom of the lifting component 61. The lifting component 61 controls the dust removal component 62 and the cleaning component 63 to rise and fall alternately.

[0021] As a preferred embodiment, the lifting assembly 61 further includes a first bracket 611 installed at the top of the inner cavity of the frame 3. The first guide rods 612 are vertically inserted into the left and right sides of the upper surface of the first bracket 611. The two first guide rods 612 fix the dust removal assembly 62 and the cleaning assembly 63 respectively. A first motor 613 is installed at the bottom of the first bracket 611. A gear 614 is installed at the output end of the first motor 613. The gear 614 has racks 615 meshing with the left and right sides of its outer wall. When the first motor 613 drives the gear 614 to rotate clockwise or counterclockwise, the two racks 615 can move in opposite directions, rising and falling alternately, so that the dust removal assembly 62 and the cleaning assembly 63 can work alternately. Before polishing, the first motor 613 drives the gear 614 to rotate clockwise or counterclockwise. Under the transmission condition of the gear 614 and the rack 615, the dust removal component 62 and the cleaning component 63 alternately rise and fall to adjust the operation mode. During polishing, the dust removal component 62 pre-treats the wood veneer, and when unloaded, the cleaning component 63 cleans impurities from the surface of the polishing roller 73.

[0022] As a preferred embodiment, the dust removal assembly 62 further includes an air knife 621 installed at the bottom of the first guide rod 612 on the left side. The length of the air knife 621 is greater than the width of the wood veneer to ensure that the wood veneer is fully vacuumed. The air knife 621 is installed on the right side with the rack 615. The air knife 621 is used to remove impurities from the surface of the wood veneer. A first connecting pipe 622 is vertically installed at the top center of the air knife 621 and is inserted into the inner cavity of the branch pipe 43. A first sealing ring 623 is installed at the top of the first connecting pipe 622. When the first sealing ring 623 contacts the baffle 44, the air hole 45 is closed. When the dust removal component 62 descends, the first connecting pipe 622 moves away from the branch pipe 43, the air hole 45 opens, and the air knife 621 sucks away impurities on the surface of the wood veneer, preventing hard particle impurities from rolling and pressing the wood veneer when the polishing roller 73 polishes the wood veneer, thus avoiding scratches or damage to the wood veneer.

[0023] As a preferred embodiment, the cleaning component 63 further includes a second bracket 631 installed at the bottom of the first guide rod 612 on the right side, with the left side of the second bracket 631 mounted to the rack 615. A second connecting pipe 632 is vertically installed at the top center of the second bracket 631 and is inserted into the inner cavity of the branch pipe 43. A second sealing ring 633 is installed at the top of the second connecting pipe 632. The second sealing ring 633 moves upward to contact the baffle 44, thereby closing the air hole 45. Second guide rods 634 are inserted into the bottom ends of both the front and rear sides of the second bracket 631, and the inner side of the second guide rods 634 is equipped with... There is an air duct 635, and the second guide rod 634 constrains the air duct 635 to move in a straight line. The center of the upper surface of the air duct 635 is connected to the bottom end of the second connecting pipe 632 through an air pipe. Several brushes 636 and suction nozzles 637 are alternately installed on the lower surface of the air duct 635 from front to back. When the brushes 636 move, they brush and clean the polishing mechanism 7, loosening the impurities on the polishing mechanism 7. Then, the impurities are sucked away by the suction nozzles 637. The drive unit 638 is installed on the top front of the second bracket 631, and the roller 639 is installed on the top of the air duct 635. The drive unit 638 and the roller 639 work together to drive the air duct 635 to swing back and forth. By adjusting the shape of the guide groove 6383, the roller 639 moves in a certain direction, allowing the brush 636 to repeatedly clean impurities on the surface of the polishing roller 73, thus cleaning the polishing roller 73 and restoring its polishing ability.

[0024] As a preferred embodiment, the drive unit 638 further includes a second motor 6381 mounted on the top front of the second bracket 631. A rotating drum 6382 is mounted on the output end of the second motor 6381. A guide groove 6383 is provided on the outer wall of the rotating drum 6382, and a roller 639 is inserted into the inner cavity of the guide groove 6383. The guide groove 6383 is distributed in a wave-like manner on the outer wall of the rotating drum 6382. The guide groove 6383 has inclined surfaces in two directions. As the rotating drum 6382 rotates, the inclined surfaces of the guide groove 6383 alternately press the roller 639 forward and backward, thereby realizing the back-and-forth swing of the air duct 635. When the cleaning component 63 descends, the second connecting pipe 633 moves away from the branch pipe 43, the brush 636 contacts the polishing roller 73, the second motor 6381 drives the rotating drum 6382 to rotate, the inclined surfaces of the guide groove 6383 in different directions squeeze the roller 639, causing the air duct 635 to swing back and forth, allowing the brush 636 to move the wood veneer debris attached to the surface of the polishing roller 73, loosening the debris, and then sucking away the impurities through the suction nozzle 637, thus cleaning the polishing roller 73, keeping the polishing roller 73 at its original roughness, and preventing the wood veneer polishing from being obstructed.

[0025] As a preferred embodiment, the sanding mechanism 7 further includes a polishing frame 71 installed at the bottom of the inner side of the frame 3, a third motor 72 installed at the rear of the polishing frame 71, and a polishing roller 73 installed at the output end of the third motor 72. The third motor 72 drives the polishing roller 73 to rotate, thereby achieving the sanding of the wood veneer by the polishing roller 73. The wood veneer moves from left to right along the conveyor 2, and the third motor 72 drives the polishing roller 73 to rotate. The polishing roller 72 polishes the wood veneer.

[0026] As a preferred embodiment, the gluing mechanism 8 further includes a frame 81 mounted on the right end of the workbench 1. A drive roller 82 and a gluing roller 83 are mounted from left to right on the left side of the inner side of the frame 81 via bearings. A gearbox 84 is mounted on the left side of the front of the frame 81, driving the drive roller 82 and the gluing roller 83 to rotate in opposite directions, conveying the wood veneer from top to bottom. A fourth motor 85 is mounted on the front of the gearbox 84 to drive its rotation. A guide plate 86 is mounted on the inner side of the frame 81. The guide plate 86 is inclinedly distributed at the top between the drive roller 82 and the glue-applying roller 83. The guide plate 86 changes the direction of the wood veneer movement and guides the wood veneer between the drive roller 82 and the glue-applying roller 83. A glue box 87 is installed inside the frame 81. Glue is applied to the glue-applying roller 83 through the glue box 87. A detachable scraper 88 is installed on the top of the glue box 87. The scraper 88 is used to scrape off excess glue from the surface of the glue-applying roller 83. The glue-applying roller 83 evenly applies glue to the surface of the wood veneer, giving the wood veneer a flame-retardant and waterproof treatment. After the wood veneer is polished, the inclined surface of the guide plate 86 guides the wood veneer to move between the drive roller 82 and the glue-applying roller 83. Under the transmission condition of the gearbox 84, the drive roller 82 and the glue-applying roller 83 rotate in opposite directions, so that the wood veneer is conveyed from top to bottom. Under the obstruction of the scraper 88, the glue is evenly distributed on the glue-applying roller 83, so that the glue-applying roller 83 can evenly apply the glue to the surface of the wood veneer. The support plate 9 supports the wood veneer after the glue is applied.

[0027] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

8. The sanding and gluing integrated machine for processing flame-retardant and waterproof wood veneer according to claim 7, characterized in that, The gluing mechanism (8) includes a frame (81) installed on the right end of the workbench (1). A transmission roller (82) and a gluing roller (83) are mounted from left to right on the left side of the inner side of the frame (81) via bearings. A gearbox (84) is installed on the left side of the front of the frame (81). The gearbox (84) drives the transmission roller (82) and the gluing roller (83) to rotate in opposite directions, conveying the veneer from top to bottom. A fourth motor (85) is installed on the front of the gearbox (84) to drive its rotation. The frame (81)... 1) A guide plate (86) is installed on the inner side, and the guide plate (86) is inclinedly distributed on the top between the transmission roller (82) and the glue roller (83). The guide plate (86) is used to change the direction of the wood veneer movement. A glue box (87) is installed on the inner side of the frame (81). Glue is applied to the glue roller (83) through the glue box (87). A detachable scraper (88) is installed on the top of the glue box (87). The scraper (88) is used to scrape off the excess glue on the surface of the glue roller (83) so that the glue roller (83) can evenly apply glue to the wood veneer.

9. A sanding and gluing process for processing flame-retardant and waterproof wood veneer, applied in a sanding and gluing integrated machine for processing flame-retardant and waterproof wood veneer as described in claim 8, characterized in that, Includes the following steps: Step 1: The wood veneer moves from left to right along the conveyor (2). The third motor (72) drives the polishing roller (73) to rotate. The polishing roller (72) polishes the wood veneer. A vacuum cleaner is set between the frame (3) and the glue application mechanism (8) to suck up the wood chips on the surface of the polished wood veneer. Step 2: When the wood veneer touches the guide plate (86), the inclined surface of the guide plate (86) acts as a guide, allowing the wood veneer to move between the drive roller (82) and the glue roller (83). Under the transmission conditions of the gearbox (84), the drive roller (82) and the glue roller (83) rotate in opposite directions, so that the wood veneer is conveyed from top to bottom. Under the obstruction of the scraper (88), the glue is evenly distributed on the glue roller (83), allowing the glue roller (83) to evenly apply the glue to the surface of the wood veneer. The support plate (9) supports the wood veneer after the glue application is completed. Step 3: Before polishing, the first motor (613) drives the gear (614) to rotate clockwise or counterclockwise. Under the transmission conditions of the gear (614) and rack (615), the dust removal component (62) and the cleaning component (63) alternately rise and fall to adjust the operation mode. Step 4: When the dust removal component (62) descends, the first connecting pipe (622) moves away from the branch pipe (43), the air hole (45) opens, and the air knife (621) sucks away impurities on the surface of the wood veneer, preventing hard particle impurities from rolling and pressing the wood veneer when the polishing roller (73) polishes the wood veneer, thus avoiding scratches or damage to the wood veneer. Step 5: When the cleaning component (63) descends, the second connecting pipe (633) moves away from the branch pipe (43), the brush (636) contacts the polishing roller (73), the second motor (6381) drives the rotating drum (6382) to rotate, and the inclined surfaces of the guide groove (6383) in different directions squeeze the roller (639), causing the air duct (635) to swing back and forth, allowing the brush (636) to move the wood veneer debris attached to the surface of the polishing roller (73), loosening the debris, and then sucking away the impurities through the suction nozzle (637), thus cleaning the polishing roller (73), keeping the polishing roller (73) at its original roughness, and preventing the wood veneer polishing from being obstructed.
