Description

Technical Field

[0001] This invention relates to the field of plywood manufacturing technology, and more specifically, to a method and equipment for applying glue to the interlocking joints of wood planks. Background Technology

[0002] In recent years, the vertical splicing and finger jointing process for raw plywood has been widely used in the plywood manufacturing industry and has played a significant role. Since raw plywood (i.e., wood boards) is processed from naturally grown trees, the quality of the splicing (i.e., finger jointing) is related to many factors, such as the thickness of the wood board, the grade of the wood board, the application of glue to the finger joint, and the force distance during splicing. Therefore, high requirements are placed on the finger jointing equipment.

[0003] Existing toothed jointing equipment has the following obvious defects in actual production:

[0004] The existing equipment uses a single glue applicator at a single glue application position, which limits the glue application range at the interface. Insufficient glue application results in poor interface stress, leading to a high rate of interface breakage in subsequent processing steps, causing material waste and labor costs for remedial processes.

[0005] The existing equipment uses one gluing device with two gluing positions. The glue scraper is limited by the device itself, making it difficult to control the amount of glue added to the parts. During gluing, excess hot melt glue sticks to two adjacent surfaces of the interface (these two surfaces are not the target surfaces for hot melt glue application; in subsequent plywood processing, at least one surface needs to be coated with a non-hot melt adhesive). The excess hot melt glue occupies the gluing position for subsequent applications, preventing the glue from being applied directly to the wood surface. In actual subsequent hot pressing production, wood boards often experience delamination or bulging due to excessive glue application, resulting in a higher plywood defect rate. Excessive glue application also causes inconsistent board thickness, increasing the difficulty of subsequent processing.

[0006] The existing equipment uses two gluing devices at two gluing positions, which occupies a large area and increases the distance between the drive rollers on both sides (meaning the force distance for joining the wood boards is increased). When splicing the wood boards, the large force distance results in uneven stress on the boards, easily leading to misalignment at the joints and damage to the boards. In addition, equipment using two gluing devices has a high cost, a higher failure rate, and requires more time-consuming regular cleaning during use. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for applying glue to the finger joint of plywood semi-finished wood boards by changing the glue application position of the finger joint. This method can achieve glue application to the target glue application position of each of the two wood boards by changing the glue application position of the glue application device, and effectively reduce glue application to the target glue application position and reduce hot melt glue loss, improve the quality of wood board splicing, reduce equipment cost, and reduce production cost.

[0008] Another object of the present invention is to provide a device for applying adhesive to the toothed joint of a wooden board for implementing the above method.

[0009] The technical solution of this invention is: a method for applying glue to the toothed joint of a wooden board, wherein the glue applicator is provided with a glue applicator that rotates approximately 180 degrees from the glue tank to the rearward glue applicator position. During this process, a scraper provided on the rotation path of the glue applicator scrapes off excess glue. The toothed structure of the rearward conveyed wooden board is glued to the glue applicator located at the rearward glue applicator position. The toothed structure of the glued wooden board moves forward to avoid the glue applicator and repositions. The glue applicator repositions to the forward glue applicator position, and the toothed structure of the forward conveyed wooden board is glued to the glue applicator located at the forward glue applicator position. The glue applicator rotates approximately 180 degrees back to the glue tank to replenish glue. During this process, the glue applicator returns to its initial position.

[0010] This invention provides a device for gluing and repositioning the toothed joints of wooden boards to implement the above-mentioned method. Along the feeding to discharging direction, it includes a first conveying device that allows wooden boards to enter and forwardly conveys them; a cutting device that cuts the wooden boards and forms a toothed structure on their edges; a second conveying device that cooperates with the first conveying device to forwardly convey the wooden boards for gluing and for joining the boards; a gluing device that applies gluing to the toothed structure of rearward-conveyed wooden boards, and after repositioning, applies gluing to the toothed structure of forward-conveyed wooden boards; a pressing device that keeps the toothed structure of the joined wooden boards flat; and a third conveying device that backward-conveys the wooden boards for gluing and forward-conveys them.

[0014] The glue application device includes a glue tank, a glue applicator, a glue scraper, a torsion drive component, and a repositioning drive component. The torsion drive component can drive the glue applicator to either a rearward glue application position or a replenishment glue position. The glue applicator in the rearward glue application position can apply glue to the toothed structure of the rearward-conveyed wooden board, while the glue applicator in the replenishment glue position can replenish glue in the glue tank. After the toothed structure of the rearward-conveyed wooden board is glued, the repositioning drive component drives the glue applicator in the rearward glue application position to the forward glue application position. The toothed structure of the forward-conveyed wooden board can then be repositioned in the glue tank. After the adhesive is applied to the toothed structure of the forward-conveyed wooden board, the torsion drive component drives the adhesive applicator back into the glue tank for additional glue. To ensure that the amount of glue added to the adhesive applicator is appropriate, the glue scraper can scrape off the excess glue on the adhesive applicator. The adhesive applicator is equipped with a retaining ring and a bushing, and the bushing connects to the glue scraper. The glue tank, the adhesive applicator, and the glue scraper are all equipped with heating devices to keep the hot melt adhesive at a suitable working temperature. For easy cleaning and glue addition, a cylinder located below the glue tank can drive the glue tank to descend, creating a larger operating space.

[0015] The pressing device includes an upper pressing seat, a lower pressing seat, and a pressing drive component.

In order to ensure the stability of the upper shears' lifting and lowering, the frame is equipped with two guide columns to guide the upper blade holder to lift and lower.

[0019] The fourth conveying device, located in front of the shearing device, is capable of outputting the wooden board forward.

[0020] A device for repositioning and gluing the toothed joint of a wooden board includes a method for repositioning and gluing the toothed joint of a wooden board, comprising the following steps: (1) The wooden board is conveyed to the target station: The first wooden board enters from the first conveyor device, and then the first conveyor device conveys the first wooden board forward to the second and third conveyors. The second and third conveyors continue to convey the end of the first wooden board forward and pause when it reaches the toothing position; (2) The wooden board is toothed: The toothing device cuts a toothed structure at the end of the first wooden board, and at the same time, the two upper rollers of the second conveyor device rise to form a channel, and the toothing device returns to form a channel; (3) The first wooden board arrives at the station to wait for gluing: The third conveyor device conveys the toothed structure of the first wooden board forward to the gluing avoidance position to wait for gluing, and the second conveyor device... (4) The next board is conveyed to the cutting position, and the gluing component is in place: The second board enters from the first conveying device and is conveyed forward to the cutting position by the first conveying device and pauses. At the same time, the torsion drive component of the gluing device drives the gluing component to the rear gluing position. During this period, the scraper scrapes off the excess glue on the gluing component; (5) Return after gluing: The third conveying device conveys the toothed structure of the first board backward to the set rear gluing position to complete the gluing. Then, the third conveying device conveys the toothed structure of the first board forward back to the gluing avoidance position. At the same time, the cutting device cuts the toothed structure at the beginning of the second board and the cutting device returns to form a channel; (6) The gluing component of the gluing device is repositioned: The repositioning drive component of the gluing device is repositioned. (7) Glue application of the first conveyor: The second wood board is conveyed forward by the first conveyor into the second conveyor. Then, the first and second conveyors simultaneously convey the toothed structure of the second wood board to the set forward glue application position to complete the glue application. Then, the torsion drive component of the glue application device drives the glue application component located in front of the toothed structure of the second wood board to return to the glue tank to replenish glue. The repositioning drive component of the glue application device then drives the glue application component back to its original position. (8) Gear jointing: The third conveyor conveys the first wood board forward so that the toothed structure of the first wood board enters the pressing device and is in the mating position. During this period, the first and second conveyors simultaneously convey the second wood board forward so that the toothed structure of the second wood board is in the mating position. The shaped structure enters the pressing device to the docking position. Then, the pressing device presses down to keep the toothed structure of the spliced ​​wooden board flat. At the same time, the positioning device presses down to fix the position of the first wooden board. Then, the first conveying device and the second conveying device simultaneously convey the second wooden board forward so that the toothed structure of the second wooden board reaches the docking position in the pressing device. The toothed structure of the spliced ​​wooden board is squeezed and tightly bonded. The pressing device and the positioning device return to their positions to form a channel. (9) Remove the teeth from the end of the spliced ​​long wooden board: The first conveying device, the second conveying device and the third conveying device simultaneously convey the spliced ​​long wooden board forward so that the end of the spliced ​​long wooden board stops when it reaches the toothed position. (10) Repeat the process 2-8 to splice the third wooden board and the long wooden board together again to form a longer wooden board.(11) The first, second, and third conveying devices synchronously transport the re-extended wooden boards forward, pausing when the end of the board reaches the toothed position. Then, the toothed device cuts a toothed structure at the end of the board. Simultaneously, the two upper rollers of the second conveying device rise to form a channel, and the toothed device returns to form a channel. The third conveying device transports the board to a predetermined size and pauses. The shearing device presses down to cut the board, and the shearing device returns to form a channel. The fourth conveying device presses down to output the cut board to the equipment for connection to subsequent equipment or stacking. The fourth conveying device returns to form a channel, and the third conveying device continues to transport the toothed structure of the board forward to the glue application avoidance position. The two upper rollers of the second conveying device descend to return to their positions. (12) Repeating steps 4-11 can achieve continuous splicing of wooden boards.

[0021] A method for applying glue to the toothed joint of a wooden board includes the following steps: (1) The first wooden board arrives at the work station to wait for glue application: The third conveying device transports the toothed structure of the first wooden board forward to the glue application avoidance position to wait for glue application, and the two upper rollers of the second conveying device descend back to their original positions; (2) The next wooden board is transported to the tooth cutting position, and the glue application component is positioned at the same time: The second wooden board enters from the first conveying device and is paused when it is transported forward to the tooth cutting position by the first conveying device. At the same time, the torsion drive component of the glue application device drives the glue application component to the rear glue application position. During this period, the glue scraper scrapes off the excess glue on the glue application component; (3) Returning to the original position after glue application: The third conveying device transports the toothed structure of the first wooden board backward to the set rear glue application position to complete the glue application. Then, the third conveying device returns to its original position. The device forward conveys the toothed structure of the first wooden board back to the glue application avoidance position. At the same time, the tooth cutting device cuts the toothed structure at the first end of the second wooden board, and the tooth cutting device returns to form a channel; (4) The glue application part of the glue application device is repositioned: the repositioning drive component of the glue application device drives the glue application part of the glue application device to the forward glue application position; (5) The wooden board is conveyed forward for glue application: the second wooden board is forward conveyed by the first conveying device into the second conveying device. Then, the first conveying device and the second conveying device simultaneously convey the toothed structure of the second wooden board forward to the set forward glue application position to complete the glue application. Then, the torsion drive component of the glue application device drives the glue application part located in front of the toothed structure of the second wooden board to return to the glue groove to replenish glue. The repositioning drive component of the glue application device then drives the glue application part to return to the position.

[0022] The principle of the above-mentioned method and equipment for applying glue to the toothed joint of a wooden board is as follows: the glue applicator rotates approximately 180 degrees from the glue tank to the rearward glue application position. During this process, a scraper located on the rotation path of the glue applicator scrapes off excess glue. The toothed structure of the rearward-conveyed wooden board applies glue to the glue applicator at the rearward glue application position. The toothed structure of the glued wooden board moves forward to avoid the glue applicator and repositions. The glue applicator then moves to the forward glue application position, and the toothed structure of the forward-conveyed wooden board applies glue to the glue applicator at the forward glue application position. The glue applicator rotates approximately 180 degrees back to the glue tank to replenish glue. During this process, the glue applicator returns to its initial position. This invention relates to a method and equipment for applying adhesive to the toothed joint of wooden boards. It reduces the space occupied by an adhesive applicator, shortens the extrusion force distance, and improves the stress performance of the wooden boards during toothed joint extrusion. It effectively prevents situations where the joint is not properly extruded due to a large extrusion distance or the wooden boards are crushed. The joint of the wooden boards is firm, reducing downtime due to failure, lowering equipment costs, improving the operational stability of the toothed joint, and also increasing production efficiency.

[0023] Compared with the prior art, the present invention has the following advantages or beneficial effects:

[0024] This invention relates to a method and equipment for applying glue to the joint of wood panels by repositioning. It improves upon existing methods and equipment for gluing wood panels by reducing the number of gluing devices from two to one. The gluing device itself is repositioned to create two gluing positions, allowing gluing to be applied to two different target locations. Furthermore, when reapplying glue, excess glue can be scraped off by a scraper on the gluing device, preventing excessive glue from being applied outside the target gluing area. Since the quality of the wood panel joint is greatly affected by the thickness of the wood and the compression distance, reducing the space occupied by one gluing device shortens the compression distance, resulting in better stress resistance during the jointing process. This reduces manufacturing costs and cleaning time, strengthens the joint, improves joint quality, and effectively prevents incomplete jointing or damage to the wood due to excessive compression distance, thus reducing downtime and improving the operational stability of the jointing system.

[0025] In this method and equipment for gluing and repositioning the toothed joint of wooden boards, the process from the first wooden board being conveyed backward for gluing to the completion of the gluing device repositioning, and the process from the second wooden board reaching the pre-cutting tooth position to the second wooden board entering the second conveying device, are carried out simultaneously. After the second wooden board is glued, its continued forward conveying does not conflict with the direction of the gluing rod returning forward and downward. This reduces the time it takes for the second wooden board to avoid the return of the gluing device. Compared with traditional gluing methods and equipment, this shortens the board splicing time, improves production efficiency, simplifies the process, and also makes the equipment easier to operate.

[0026] In this method and equipment for applying glue to the joint of a wooden board, the glue scraper is positioned on the path of the glue applicator, which can scrape off excess glue during the application process, reducing the amount of glue used. This avoids a large amount of hot melt glue blocking subsequent application of other types of glue directly onto the wooden board, reducing the occurrence of the board opening and bulging due to heat during production or use, and reducing the occurrence of the joint becoming thicker due to excessive glue application. This improves product quality and reduces glue consumption.

[0027] In this method and equipment for applying adhesive to the toothed joint of a wooden board, the adhesive application device applies adhesive to the toothed structure of the board facing backward and forward respectively, thereby increasing the target adhesive application area of ​​the board. This makes it less likely for the joint to fall off during production. Even if the joint is cut during production, the large adhesive application area of ​​the toothed joint reduces the occurrence of joint detachment, thus reducing board waste and remedial time.

[0050] Multiple devices of a wood board toothed joint repositioning and gluing device can be set on one or more frames. During splicing, the wood board enters from one side of the frame and exits from the other side. In some embodiments, the device includes the following steps: (1) The first wood board 01 enters the board inlet position through the gap between the first lower roller 12 and the first upper roller 14. The first cylinder 15 drives the first upper roller 14 to press down and clamp the first wood board 01. The first conveying device 1 conveys the first wood board 01 forward (in this step, the first conveying device, the second conveying device, and the third conveying device rotate synchronously).

When the second wooden board 02 enters the gap between the first lower roller 12 and the first upper roller 13, the first cylinder 15 drives the first upper roller 14 to rise and return to its original position to form a channel (form a gap). The first conveying device 1 continues to convey the first end of the second wooden board 02 forward and pauses when it reaches the tooth cutting position. At the same time, the torsion... The rotary drive cylinder 405 drives the glue applicator 42 to rotate the glue applicator teeth 41 forward and upward by about 180 degrees to reach the glue applicator position; (5) The drive cylinder 27 of the tooth cutting device 2 drives the upper tooth cutter 23 to press down and cooperate with the lower tooth 21 to cut the tooth structure at the first end of the second wooden board 02. The drive cylinder 27 of the tooth cutting device 2 drives the upper tooth cutter 23 to rise and return to the position to form a channel. At the same time, the third conveying device 6 conveys the tooth structure of the first wooden board 01 backward to the glue applicator position for glue application. Then, when the third conveying device 6 conveys the tooth structure of the first wooden board 01 forward back to the glue applicator position, it pauses. The shift drive cylinder 404 drives the glue applicator 42 to shift the glue applicator teeth 41 to the forward glue applicator position.(6) The first conveying device 1 conveys the second wooden board 02 forward. After the second wooden board 02 enters the second conveying device 3, the first conveying device 1 and the second conveying device 3 convey the toothed structure of the second wooden board 02 forward to the forward gluing position for gluing. The torsional drive cylinder 405 drives the gluing teeth 41 located at the forward gluing position to rotate forward and downward back into the glue tank 40 to replenish the glue. The third conveying device 6 conveys the toothed structure of the first wooden board 01 forward into the pressing device 5 to the docking position. At the same time, the first conveying device 1 and the second conveying device 3 convey the toothed structure of the second wooden board 02 forward into the pressing device 5 to the docking position. (7) Pressing device The cylinder 53 of the 5th position drives the upper pressure seat 52 to press down, so that the toothed structure of the spliced ​​wooden board remains flat. At the same time, the cylinder 73 of the positioning device 7 drives the upper fixing seat 72 to press down and fix the position of the first wooden board 01. Meanwhile, the displacement driving cylinder 404 drives the glue applicator 42 to make the glue applicator teeth 41 return to their original position. The first conveying device 1 and the second conveying device 3 convey the toothed structure of the second wooden board 02 forward to reach the docking position in the pressing device 5. The toothed structure of the spliced ​​wooden board is squeezed and tightly bonded. The pressing device 5 and the positioning device 7 return to their original positions to form a channel; (8) The first conveying device 1 and the second conveying device 3 cooperate with the third conveying device 6 When the end of the spliced ​​wooden board is conveyed forward to the cutting position set by the third conveying device 6, the third conveying device pauses, and the first conveying device 1 and the second conveying device 3 stop conveying the spliced ​​wooden board; (9) Repeat the process of 2-8 so that the end of the spliced ​​wooden board pauses when it reaches the cutting position; (10) The driving cylinder 27 of the cutting device 2 drives the upper toothed cutter 23 to press down and cooperate with the lower toothed cutter 22 to cut a toothed structure at the end of the spliced ​​wooden board. At the same time, the second cylinder 34 of the second conveying device 3 drives the second upper roller 33 to rise to form a channel (or form a gap), and the driving cylinder 27 of the cutting device 2 drives the upper toothed cutter 23 to rise. The third conveyor 6 pauses when the board is conveyed forward to the predetermined size, the hydraulic cylinder 85 of the shearing device 8 drives the upper shears 82 to press down and cut the board. The hydraulic cylinder 85 drives the upper shears 82 to rise and return to form a channel. The cylinder 94 of the fourth conveyor 9 drives the upper roller 93 to press down and output the cut board, which is then connected to subsequent equipment or stacked. The fourth conveyor 9 returns to form a channel, and the third conveyor 6 continues to convey the toothed structure of the board to the glue-coating avoidance position. The second cylinder 34 of the second conveyor 3 drives the second upper roller 33 to descend and return to its original position. (11) Repeating steps 4-10 can achieve continuous splicing of the boards. The above technical solution for splicing boards with glue coating results in a firm joint with less glue, effectively preventing situations where the joint is not properly squeezed or the board is crushed due to a large extrusion distance. This reduces downtime, lowers equipment costs, improves the operational stability of the toothed joint, and increases production efficiency.

[0051] In some embodiments, see Figure 1The first conveying device 1 includes multiple first upper rollers 13 and 14, multiple first lower rollers 12, multiple first roller seats, and a first motor 10. The multiple first roller seats are respectively equipped with first cylinders 15 and 16 that can drive the first upper rollers 13 and 14 and / or the first lower rollers 12 to move closer or separate from each other. The first motor 10 can drive the multiple first lower rollers 12 and / or the first upper rollers 13 to convey wooden boards. The board feeding method can be that the worker feeds the board forward into the board feeding position between the first lower roller 12 and the first upper roller 14, or the board feeding mechanism can be used to input the board from one side into the board feeding position between the first lower roller 12 and the first upper roller 14. Then, the first cylinder 15 drives the first upper roller 14 to press down and clamp the board, and the first motor 10 drives the board forward into the first lower roller 12 and the first upper roller 13. Afterward, the first cylinder 15 drives the first upper roller 14 to return to its original position to form a gap, waiting for the next board to enter. The first conveying device 1 can set the cutting position of the cutting teeth at the beginning of the wooden board, set the forward glue application position of the toothed structure at the beginning of the wooden board, set the position to be joined by the toothed structure at the beginning of the wooden board, and set the joining position of the toothed structure at the beginning of the wooden board.

[0052] In some embodiments, see Figure 1 The cutting device 2 includes a frame, two drive cylinders 27, an upper toothed cutter 23, a lower toothed cutter 21, a lower toothed cutter 22, an upper cutter holder 29, a material ejector plate 24, and a material ejector plate 25. The output ends of the two drive cylinders 27 are equipped with the upper cutter holder 29, and the upper toothed cutter 23 is mounted on it. The frame is equipped with the lower toothed cutter 21 and the lower toothed cutter 22, which have rear angles to facilitate material ejection. The material ejector plates 24 and 25 are connected to the upper cutter holder 29 via springs 26 and adjusting rods 28. A waste discharge plate 28 is located below the cutting device 2. To ensure the stability of the upper toothed cutter 23's movement, synchronous gears at both ends of the upper cutter holder mesh with racks at both ends of the frame. The gears at both ends of the upper cutter holder are connected by a shaft to achieve synchronous rotation. The precision frame of the cutting machine, which cooperates with the upper toothed cutters 21 and 22 during tooth cutting, is equipped with two guide columns that guide the upper cutter holder 29 to rise and fall. When cutting the teeth at the end of the wooden board, the two drive cylinders 27 drive the toothed cutting edge in front of the upper toothed cutter 23 to cooperate with the toothed cutting edge of the lower toothed cutter 22 to cut a toothed structure at the end of the wooden board. The ejector plate 25 exits the toothed structure at the end of the wooden board, and the cutting waste falls from the lower toothed cutter 22 onto the inclined surface of the waste discharge plate 28 and is discharged from the equipment. When cutting the teeth at the beginning of the wooden board, the two drive cylinders 27 drive the toothed cutting edge behind the upper toothed cutter 23 to cooperate with the toothed cutting edge of the lower toothed cutter 21 to cut a toothed structure at the beginning of the wooden board. The ejector plate 24 exits the toothed structure at the beginning of the wooden board, and the cutting waste falls from the lower toothed cutter 21 onto the inclined surface of the waste discharge plate 28 and is discharged from the equipment.

[0053] In some embodiments, the first conveying device 1 and the second conveying device 3 may be driven by the same motor, but are not limited to this one. Preferably, see [link to previous document]. Figure 1 The second conveying device 3 includes two second upper rollers 33, two second lower rollers 32, two second roller seats, and a second motor 30. The two second roller seats are respectively equipped with second cylinders 34 that can drive the second upper rollers 33 and / or the second lower rollers 32 to approach or separate from each other. The second motor 30 can drive the second lower rollers 32 and / or the second upper rollers 33 to convey the wooden boards. In order to cool down and prevent glue from sticking to the roller surface, the two second upper rollers 33 and / or the two second lower rollers 32 are equipped with cooling circulating water channels. The second conveying device 3 assists the first conveying device 1 in conveying wooden boards and shortens the force distance of the toothed (splicing) joint. It can make the wooden boards have better force performance and stronger thrust when they are pressed together, and can make the wooden boards less likely to slip and lose their position during conveying.

[0054] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 4 The glue application device 4 includes a glue tank 40, a glue application component 42, a glue scraper 43, a torsion cylinder 405, and a shifting cylinder 404. Preferably, the main body of the glue application component 42 is a hollow shaft 42, and the shaft ends on both sides of the glue application component 42 are respectively connected to holes provided in the fixing seats 44 and 49. The fixing seats 44 and 49 are mounted on the frame and can rotate and move to both sides with the glue application component 42. The glue application component 42 is provided with multiple glue application rods 41 that can apply glue to the toothed structure of the wooden board. A gear 4 is provided on one side of the shaft end of the glue application component 42. 01. The torsional cylinder 405 is mounted on the frame. The output end of the torsional cylinder 405 has a rack 402 that meshes with the gear 401. A guide wheel 403 on the fixed base 44 guides the rack 42. When the torsional cylinder 405 drives the rack 402 upwards, it meshes with the gear 401, causing multiple glue-applying rods 41 to rotate approximately 180 degrees forward and upward from the glue tank 40 to the rearward glue-applying position. The output end of the shifting cylinder 404 on the fixed base 44 is connected to the glue-applying component 42 via a rotary joint or a torsional element. See [link to relevant documentation]. Figure 3 The initial position of the shifting cylinder 404 is set at the rearward glue application position corresponding to the glue application component 42. At this time, the multiple glue application rods 41 correspond to the positions of the multiple tooth roots 011 of the toothed structure of the first 01 wooden board, enabling the multiple tooth roots 011 to the tooth waist position of the toothed structure of the rearward conveying wooden board to be glued; see Figure 4The termination position of the extension of the shifting cylinder 404 is set at the forward gluing position of the corresponding gluing component 42. At this time, the multiple gluing rods 41 correspond to the positions of the multiple tooth roots 021 of the toothed structure on the edge of the second 02 wooden board, enabling the multiple tooth roots 021 of the toothed structure of the forward conveying wooden board to be coated with glue. The main body of the scraper 43 is also a hollow shaft 43. The shaft ends on both sides of the scraper 43 are respectively connected to the holes provided in the fixing seat 44 and the fixing seat 49. The multiple scraping nozzles 45 provided on the scraper 43 are located on the path of the multiple gluing rods 41 to reciprocate and replenish glue, which can scrape off excess hot melt glue and drop it into the glue tank 40 below. Considering that when the shifting cylinder 404 drives the gluing component 42 to shift, the scraper 43 can follow the gluing component. The multiple glue applicators 41 move together to ensure that they can pass through the multiple glue scraping nozzles 45 on the glue application path at any time. The glue applicator 42 is equipped with a bushing 46 that can rotate with the glue applicator 42. The bushing 46 is connected to the glue scraper 43. The positioning retaining rings 47 and 48 on the glue applicator 42 enable the bushing 46 and the glue scraper 43 in the middle to move together with the glue applicator 42 when changing positions. In order to facilitate cleaning of the glue tank 40 and to facilitate glue addition, the cylinder 45 connected to the glue tank 40 can drive the glue tank 40 to descend to realize a larger operating space. The frame is equipped with two guide columns that can guide the glue tank 40 to rise and fall. The glue tank 40, the glue applicator 42 and the glue scraper 43 are all equipped with heating devices to keep the hot melt glue at a suitable working temperature.

[0055] It should be noted that the width of the multiple squeegee openings 45 provided on the squeegee part 43 is equal to the width of the tooth waist of the tooth structure of the wooden board (the width of the tooth waist refers to the width of the tooth structure of the wooden board from the tooth tip to the center of the tooth bottom). When applying glue, the glue application range set for the tooth structure of the first wooden board is from the tooth waist to the tooth bottom 011, and the glue application range set for the tooth structure of the second wooden board is from the tooth waist to the tooth bottom 021. The tooth structure of the two first wooden boards, each with half of the tooth structure glued, is joined with the tooth structure of the second wooden board so that the entire joint can be glued.

[0056] In some embodiments, the rack 402 may, but is not limited to, be guided by a linear guide slider or a linear bearing to guide the reciprocating motion of the rack 402. Preferably, see [reference needed]. Figure 3 The guide wheel 403 is provided with a groove. The bottom surface of the groove allows the rack 402 to maintain a suitable transmission distance with the meshing tooth surface of the gear 401 during movement. When the shifting cylinder 404 drives the adhesive applicator 42 to move to both sides, the two sides of the groove allow the rack 402 to be placed in the groove provided by the guide wheel 403. The bearing provided on the inner diameter of the guide wheel 403 is connected to the fixed seat 44 through the shaft.

[0057] In some embodiments, see Figure 3 , Figure 4The thickness of the gear 401 and rack 402 used must be greater than the distance the adhesive coating part moves when it is repositioned. For example, if the tooth pitch of the tooth structure of the wooden board is 20 mm, and the adhesive coating part 42 located in the rear adhesive coating position moves 10 mm to the side to reposition the adhesive coating part 42 to the front adhesive coating position, using gear 401 and rack 402 with a thickness of 25 mm, even if the adhesive coating part 42 is repositioned and gear 401 moves 10 mm to the side, it will not affect the normal meshing performance of gear 401 and rack 402.

[0058] In some embodiments, see Figure 1 The pressing device 5 includes an upper pressing seat 52, a lower pressing seat 51, and two pressing drive cylinders 53. The output ends of the two pressing drive cylinders 53 are connected to the upper pressing seat 52. When the wooden boards are joined, the two pressing drive cylinders 53 drive the upper pressing seat 52 to approach the lower pressing seat 51, so that the toothed structure of the wooden boards remains flat. After the wooden boards are joined, the two pressing drive cylinders 53 drive the upper pressing seat 52 to rise and return to its original position to form a channel for the wooden boards to pass through. In order to improve the quality of the wooden board joint, the two ends of the upper pressing seat 52 are provided with adjusting bolts to adjust the pressing distance of the upper pressing seat 52, so that the upper pressing seat 52 presses down the wooden board with appropriate tightness and avoids the wooden board position being fixed. In order to cool the joint and prevent the contact surface from sticking, the upper pressing seat 52 and the lower pressing seat 51 are provided with cooling circulating water channels.

[0059] In some embodiments, see Figure 1 The third conveying device 6 includes two upper rollers 63, two lower rollers 62, two roller seats, and a third motor 60. The two roller seats are respectively equipped with third cylinders 64 that can drive the upper rollers 63 and / or the lower rollers 62 to approach or separate from each other. The third motor 60 can drive the lower rollers 62 and / or the upper rollers 63 to convey the wooden boards. In order to cool the joint and prevent glue from sticking to the roller surface, the two upper rollers 63 and / or the two lower rollers 62 are equipped with cooling circulating water channels. The third conveying device 6 can set the cutting position of the edge cutting teeth of the end of the wooden board, the back glue application position of the toothed structure of the end of the wooden board, the avoidance position to avoid the movement of the glue application teeth 41, the docking position when the toothed structure of the end of the wooden board is docked, and the size of the spliced ​​wooden boards.

[0060] In some embodiments, see Figure 1 It can assist the third conveying device 6 in positioning. The positioning device includes a lower fixed seat 71, an upper fixed seat 72 and two cylinders 73. When the wooden boards are spliced, the two cylinders 73 drive the upper fixed seat 72 to press down to assist the third conveying device 6 in fixing the position of the wooden boards. After the wooden boards are spliced, the two cylinders 73 drive the upper fixed seat 72 to return to its original position to form a channel.

[0061] In some embodiments, see Figure 1The shearing device 8 includes a frame, two drive cylinders 85, an upper blade holder 83, an upper shear 82, a lower shear 81, and a pressure rod 84. The lower shear 81 is mounted on the frame. The output ends of the two drive cylinders 85 are connected to the upper blade holder 83. The upper shear 82 is mounted on the upper blade holder 83. The pressure rod 84 is connected to the pressure seat 83 via a spring and bolts. The two drive cylinders 85 drive the upper shear 82 to press down, cooperating with the lower shear 81 to cut the wooden board. The pressure rod 84 presses down with the upper shear 82 to fix the wooden board. When the upper shear 82 rises to reset, the pressure rod 84 rises with the upper shear 82 to form a channel. To ensure the stability of the upper shear's lifting and lowering, each end of the upper blade holder 83 is provided with a synchronous gear that can mesh with racks located at both ends of the frame. To ensure the accuracy of the cooperation between the upper shear 82 and the lower shear 81 during shearing, the frame is provided with two guide columns to guide the upper blade holder's lifting and lowering.

[0062] In some embodiments, see Figure 1 The fourth conveying device 9 includes a drive motor 91, a lower roller 92, an upper roller 93, and a cylinder 94. The drive motor 91 drives the lower roller 92 to rotate, the cylinder 94 drives the upper roller 93 to press down and output the wooden board forward, and the cylinder 94 drives the upper roller 93 to rise to form a channel.

[0063] The first, second, and third conveying devices all use servo motors and are connected to the lower and / or upper rollers via sprockets, chains, and / or gears. The fourth conveying device uses a conventional motor and is connected to the lower roller via a belt and pulleys.

[0064] Taking a certain embodiment as an example, the working process of a device for gluing the toothed joint of a wooden board is described as follows: (1) The first wooden board 01 enters the board feeding position from the gap between the first lower roller 12 and the first upper roller 14. The first cylinder 15 drives the first upper roller 14 to press down and clamp the first wooden board 01. The first conveying device 1 conveys the first wooden board 01 forward (in this step, the first conveying device, the second conveying device, and the third conveying device rotate synchronously). When the first wooden board 01 enters the first lower roller 12 and the first upper roller 13, the first cylinder 15 drives the first upper roller 14 to rise and return to its original position to form a channel (form a gap). The first wooden board 01 continues to move forward into the second conveying device 3 and the third conveying device 6. (1) When the end of the first wooden board 01 is transported to the cutting position set by the third conveyor 6 under the cooperation of the first conveyor 1 and the second conveyor 3, the third conveyor pauses and the first conveyor 1 and the second conveyor 3 stop transporting the first wooden board; (2) The driving cylinder 27 of the cutting device 2 drives the upper toothed cutter 23 to press down and cooperate with the lower toothed cutter 22 to cut a toothed structure at the end of the first wooden board 01.

The first conveying device 1 continues to convey the second wooden board 02 forward and pauses when the first end reaches the cutting tooth position. At the same time, the torsion drive cylinder 405 drives the board forward. The moving glue applicator 42 causes the glue applicator teeth 41 to rotate forward and upward by about 180 degrees to reach the backward glue applicator position; (5) The driving cylinder 27 of the cutting device 2 drives the upper toothed cutter 23 to press down and cooperate with the lower toothed cutter 21 to cut out the toothed structure at the beginning of the second wooden board 02.

At the same time, the third conveying device 6 conveys the toothed structure of the first wooden board 01 backward to the backward glue applicator position for glue applicator. Then, when the third conveying device 6 conveys the toothed structure of the first wooden board 01 forward back to the glue applicator clearance position, it pauses. The shifting driving cylinder 404 drives the glue applicator 42 to shift the glue applicator teeth 41 to the forward glue applicator position.(6) The first conveying device 1 conveys the second wooden board 02 forward. After the second wooden board 02 enters the second conveying device 3, the first conveying device 1 and the second conveying device 3 convey the toothed structure of the second wooden board 02 forward to the forward gluing position for gluing. The torsional drive cylinder 405 drives the gluing teeth 41 located at the forward gluing position to rotate forward and downward back into the glue tank 40 to replenish the glue. The third conveying device 6 conveys the toothed structure of the first wooden board 01 forward into the pressing device 5 to the docking position. At the same time, the first conveying device 1 and the second conveying device 3 convey the toothed structure of the second wooden board 02 forward into the pressing device 5 to the docking position. (7) Pressing device The cylinder 53 of the 5th position drives the upper pressure seat 52 to press down, so that the toothed structure of the spliced ​​wooden board remains flat. At the same time, the cylinder 73 of the positioning device 7 drives the upper fixing seat 72 to press down and fix the position of the first wooden board 01. Meanwhile, the displacement driving cylinder 404 drives the glue applicator 42 to make the glue applicator teeth 41 return to their original position. The first conveying device 1 and the second conveying device 3 convey the toothed structure of the second wooden board 02 forward to reach the docking position in the pressing device 5. The toothed structure of the spliced ​​wooden board is squeezed and tightly bonded. The pressing device 5 and the positioning device 7 return to their original positions to form a channel; (8) The first conveying device 1 and the second conveying device 3 cooperate with the third conveying device 6 When the end of the spliced ​​wooden board is conveyed forward to the cutting position set by the third conveying device 6, the third conveying device pauses, and the first conveying device 1 and the second conveying device 3 stop conveying the spliced ​​wooden board; (9) Repeat the process of 2-8 so that the end of the spliced ​​wooden board pauses when it reaches the cutting position; (10) The driving cylinder 27 of the cutting device 2 drives the upper toothed cutter 23 to press down and cooperate with the lower toothed cutter 22 to cut a toothed structure at the end of the spliced ​​wooden board.

The third conveyor 6 moves the wooden board forward to a predetermined size and then pauses. The hydraulic cylinder 85 of the shearing device 8 drives the upper shears 82 to press down and cut the wooden board. The hydraulic cylinder 85 drives the upper shears 82 to rise and return to form a channel. The cylinder 94 of the fourth conveyor 9 drives the upper roller 93 to press down and output the cut wooden board, which is then connected to subsequent equipment or stacked.
