Description

Technical Field

[0002] Cross-laminated timber (CLT) is a new type of wood building material, which is characterized by gluing wood with staggered horizontal and vertical grains together to achieve better strength. Cross-laminated timber (CLT) can be used to make wooden structure roofs, floors and walls, and is a suitable substitute for materials such as concrete, masonry and steel. The CLT wood structure system is a new type of wood structure system with CLT floor panels, wall panels and roof panels as the main load-bearing components. It has the advantages of high prefabrication rate, fast construction speed, convenient construction, good seismic performance, energy saving and environmental protection. It is suitable for medium and high-rise wooden structure buildings and has potential economic competitiveness.

[0003] When preparing orthogonal glued timber (CLT), first, glue is applied to the sides of multiple wooden planks, and then the multiple wooden planks are glued side by side horizontally to form a wooden board layer. Then glue is applied to the surface of the multiple wooden board layers. The multiple wooden board layers are staggered according to the horizontal and vertical grains and arranged up and down, and then glued to form orthogonal glued timber (CLT).

[0004] When preparing the wood board layer of orthogonal glued timber (CLT), the existing equipment generally adopts manual glue application, manually moves multiple wood pieces horizontally, so that the multiple wood pieces are horizontally pressed together side by side, and then pressurizes the multiple wood pieces through a pressurizing device to achieve the gluing of the wood pieces. During pressurization, since the pressurizing table in the pressurizing device is in contact with the wood pieces, glue residue is easily left on the lower surface of the pressurizing table. The pressurizing table in the pressurizing device is large and heavy, and it is inconvenient to disassemble and move it for cleaning. When directly cleaning the lower surface of the pressurizing table on the pressurizing device, there are also restrictions on the cleaning angle and cleaning direction, and there may be cleaning residues and insufficient cleaning. At the same time, the above-mentioned gluing and pressing process is partially operated manually, with poor continuity, high labor cost and low efficiency. Summary of the invention

[0024] In order to achieve the above technical purpose, another technical solution adopted by the present invention is:

[0025] A gluing and pressing method of a segmented high-frequency pressurizing device for cross-laminated timber, comprising:

[0026] Step 1, first place a plurality of wooden blocks on the first roller on the conveying plate respectively, the container inputs glue into the kit through the output pipe, the glue in the kit seeps out to the brush head through the brush, start the driving component, the driving component drives the second driven gear, the first rotating shaft, the kit, the brush and the first driven gear to rotate, and the brush applies glue to the side of the wooden block during the rotation process; the wooden block moves backward under the friction of the brush and the rolling of the first roller;

[0029] Step 4: The driving component drives the conveyor chain to continue to operate. When the pressed wooden blocks move to the bottom of the protective panel, the driving component controls the conveyor chain to stop operating.

[0030] Step 5, start the hydraulic cylinder, the hydraulic cylinder drives the support plate to move downward, the support plate drives the pressurized table and the protective panel on the high-frequency machine to move downward, so that the protective panel contacts the pressed wood blocks, and start the high-frequency machine, which transmits the high-frequency electromagnetic field to the pressed wood blocks through the pressurized table and the protective panel, so that the glue between the adjacent wood blocks is quickly cured;

[0032] The present invention prevents the glue on the wood from contaminating the lower surface of the pressurized table top by setting up a protective panel and using the protective panel, thereby effectively solving the problem of difficult glue cleaning on the pressurized table top of the high-frequency panelizing machine, and preventing the pressurized table top from short-circuiting or sparking due to excessive glue application or severe knots in the wood. At the same time, through the mutual coordination of the gluing component, the pressing component and the high-frequency pressurizing component, the continuous and automated production of segmented high-frequency pressurized orthogonal glued timber is realized, which greatly improves the work efficiency and product quality of glued timber manufacturing.

[0033] The beneficial effects of the present invention are:

[0034] (1) Before using the present invention, the protective panel must be installed on the bottom of the pressurized table by bolts and nuts, so that the protective panel maintains a flat surface and fits the pressurized table. The use of the protective panel prevents the glue on the wooden board layer from contaminating the lower surface of the pressurized table 601, effectively solving the problem that the pressurized table on the high-frequency pressurized component is large and heavy, and it is inconvenient to disassemble and move it for cleaning. When directly cleaning the lower surface of the pressurized table on the high-frequency pressurized component, there are also restrictions on the cleaning angle and cleaning direction, and there may be cleaning residues and insufficient cleaning. It can also avoid the problem of wood ignition and even plate (pressurized table) ignition caused by wood defects (such as boils, high moisture content, etc.). The material of the protective panel is similar to that of the pressurized table, and it can transmit an alternating magnetic field. The protective panel is thin and light, easy to disassemble and clean, and has a low production cost. Only two protective panels are needed. When one of the protective panels needs to be cleaned, the protective panel can be removed from the pressurized table and replaced with a new protective panel. The protective panel that needs to be cleaned can be kept for use after cleaning. Compared with the prior art, the whole process is highly automated, continuous and efficient. In summary, the use of the protective panel of the present invention prevents the glue on the wood from contaminating the lower surface of the pressurized table. Only the protective panel needs to be replaced, which effectively solves the problem of difficult glue removal on the pressurized table of the pressurized equipment.

[0035] (2) The present invention is configured by the mutual coordination of a gluing component, an adjusting and pressing component, and a high-frequency pressurizing component, wherein the gluing component lays a good bonding foundation for the subsequent pressing process, thereby improving the bonding strength and durability; the adjusting and pressing component is driven by a motor and cooperates with two light rod guide rails to achieve precise control and smooth pressure during the pressing process, thereby avoiding gluing defects caused by uneven pressure, such as misalignment, bubbles, or insufficient bonding force, and ensuring the overall quality of the glued wood; the high-frequency pressurizing component uses a high-frequency current generator to generate a high-frequency current, which passes through an induction coil to generate a strong alternating magnetic field, which is transmitted to the glue between the wood pieces through the pressurizing table and the protective panel. Under the action of the alternating magnetic field, the glue is accelerated to solidify, thereby significantly shortening the gluing cycle; thereby, continuous and automated production of the board layer in orthogonal glued wood is achieved, greatly improving the overall manufacturing efficiency and product quality of orthogonal glued wood.

[0054] Among them, Figure 2 The material receiving assembly 8 includes a connecting frame 801, in which a plurality of second rollers 802 are rotatably connected in a surface groove of the connecting frame 801, an arc frame 803 is fixedly connected at the other end of the connecting frame 801, and slide rails 804 are provided on both sides of the arc frame 803, and a first connecting rod 805 is slidably connected in the slide rail 804, the first connecting rod 805 is rotatably connected to the middle part of the placing plate 806, a hook 810 is provided at the bottom of the placing plate 806, the bottom of the placing plate 806 is rotatably connected to the bottom of the arc frame 803, the middle part is rotatably connected to one end of the second connecting rod 807, the other end of the second connecting rod 807 is rotatably connected to the sliding block 808, the sliding block 808 is slidably connected to the sliding groove 810 on the surface of the bottom plate 809, the sliding groove 810 and the sliding block 808 are elastically connected by a spring 2 811, one end of the bottom plate 809 is fixedly connected to the bottom of the arc frame 803, and the connecting frame 801 can be connected to the conveying support frame 102. The processed wood passes through the second roller 802 and enters the arc frame 803 at the rear end of the connecting frame 801. The bottom ends of the multiple glued wood squares (the multiple glued wood squares after splicing can be called the wooden board layer in orthogonal glued timber) reach the hook claw 810, and the rear wooden board layer collides with the front wooden board layer, and the front wooden board layer turns to the placement board 810, and the cycle repeats.

[0055] This embodiment also includes a plurality of humidifying nozzles 9, which are connected to the support plate 603. The plurality of humidifying nozzles 9 are connected to a water supply source through water pipes, so as to humidify and collect the wooden board.

[0056] The motor 1 201, the motor 2 503, the motor 3 504 and the high frequency machine 605 of this embodiment are all connected to the control device 304, and are controlled by the control device 304. The hydraulic cylinder 604 is connected to the hydraulic station through a pipeline and a control valve, and the hydraulic station provides hydraulic pressure for the hydraulic cylinder 604. The control device 304 is connected to the control valve to adjust the flow and pressure of the liquid, and then adjust the extension and retraction of the retracted end of the hydraulic cylinder 604.

[0057] When this embodiment is used, the output shaft of the motor 201 drives the screw 202 to rotate. When the screw 202 rotates, the first driven gear 303 is driven, thereby realizing the rotation of the conveyor chain 301. The container 401 is filled with glue through the glue loading port 402. During the rotation of the screw 202, the screw 202 drives the second driven gear 408, thereby driving the second rotating shaft 405 to rotate. The second rotating shaft 405 rotates, driving the kit 406 and the brush 407 to rotate. The container 401 inputs glue to the kit 406 and the brush 407 through the output tube 409. The wooden block is placed on the first roller 404. When the brush 407 rotates, During the process, glue is applied to the side of the wood block, and friction is generated at the same time. The wood block rolls along the first roller 404 and enters the conveyor chain belt 301. After the wood block enters the conveyor chain belt 301, the conveyor chain belt 301 conveys the wood block, and the rotating rod 506 intercepts the wood block. At this time, under the influence of the conveyor chain belt 301, the wood block will push the rotating rod 506 to move on the left guide rail 501 and the right guide rail 502 and squeeze the spring 1 507. After the rotating rod 506 intercepts multiple wood blocks, one end of the multiple wood blocks is aligned. In this embodiment, a pressure sensor can also be set between the spring 1 507 and the inner wall of the rear end of the guide groove of the left guide rail 501 and the right guide rail 502. The pressure sensor sends a pressure signal. The control device 304 transmits the value information to the control device 304, and the control device 304 determines whether the rotating rod 506 has intercepted a preset number of wooden blocks through the pressure value. If the preset number of wooden blocks have been intercepted, the control device 304 controls the motor 2 503 to rotate, thereby driving the rotating rod 506 to lift. At this time, the conveying chain belt 301 is controlled to stop conveying by the motor 1 201, and the control device 304 controls the motor 3 504 to rotate, thereby driving the second screw 505 to rotate, so that the right guide rail 502 approaches the direction of the left guide rail 501, and presses the wooden blocks between the left guide rail 501 and the right guide rail 502, so as to glue and splice multiple wooden blocks to obtain a wooden board layer. After completion, the motor 1 201 controls the motor 3 503 to rotate, thereby driving the second screw 505 to rotate. The conveyor chain 301 continues to convey, and the conveyor chain 301 transports the spliced ​​wooden board layer to the bottom of the protective panel 7. After that, the conveyor chain 301 stops conveying, and the output end of the hydraulic cylinder 604 moves, driving the support plate 603 to move downward along the high-frequency pressurized column 104, so that the pressurized table 601 and the protective panel 7 press the wooden board layer downward. At the same time, the high-frequency machine 605 is started, so that the pressurized table 601 generates an alternating magnetic field, and transmits it to the wooden board layer through the protective panel 7 (the conveyor chain 301 has a tight supporting effect on the wooden board layer), so as to realize the rapid curing of the glue. The above method adopts vertical lifting along the high-frequency pressurized column 104, and the flatness is better than that of the ordinary table inclined high-frequency splicing machine.In addition, before use, the protective panel 7 (imported panels can be used) must be installed on the bottom of the pressurized table 601 by bolts and nuts to keep the protective panel 7 flat and in contact with the pressurized table 601. The use of the protective panel 7 prevents the glue on the wooden layer from contaminating the lower surface of the pressurized table 601, and effectively solves the problem that the pressurized table 601 on the high-frequency pressurized component 6 is large and heavy, and it is inconvenient to disassemble and move it for cleaning. When the lower surface of the pressurized table 601 is cleaned directly on the high-frequency pressurized component 6, there are also restrictions on the cleaning angle and cleaning direction, and there may be cleaning residues and insufficient cleaning. It can also avoid wood ignition and even plate (pressurized table 601) ignition problems caused by wood defects (such as boils, high moisture content, etc.). The material of the protective panel 7 is similar to that of the pressurized table 601, and can transmit an alternating magnetic field. The protective panel 7 is thin and light and has a low manufacturing cost. Only two protective panels 7 are needed. When one of the protective panels 7 needs to be cleaned, the protective panel 7 can be removed from the pressurized table 601 and replaced with a new protective panel 7. The protective panel 7 is thin and light, and is also easy to disassemble and clean. The whole process is more efficient than the prior art. The processed wooden board layer passes through the second roller 802 and enters the arc frame 803 of the connecting frame 801. The bottom end of the wooden board layer reaches the hook 810. The rear wooden board layer collides with the lower surface of one end of the front wooden board layer, and the front wooden board layer turns to the placement plate 806, and the cycle is repeated, thereby accumulating the material of the wooden board layer. In addition, for a wooden board layer with a longer length, the hydraulic cylinder 604 of this embodiment can extend and retract at a certain frequency to achieve continuous high-frequency pressurization of the high-frequency machine 605 and improve the preparation efficiency. In addition, if the gluing component 4 and the adjusting and pressing component 5 above the conveyor chain 301 are disassembled, glue is applied to the wooden board layer through the gluing mechanism of the wooden board layer, and then the multiple wooden board layers after gluing are manually arranged up and down according to the horizontal and vertical grains, and placed on the conveyor chain 301, and conveyed to the bottom of the high-frequency pressurizing component 6 through the conveyor chain 301, the high-frequency pressurizing component 6 is used to pressurize the arranged wooden board layers and transmit the alternating magnetic field to achieve rapid curing of the glue, and orthogonal glued wood is obtained after the multiple wooden board layers are glued and cured.

[0058] This embodiment also provides a method for gluing and pressing a sectional high-frequency pressurizing device for cross-laminated timber, comprising:

[0059] Step 1, first place a plurality of wooden blocks on the first roller 404 on the conveying plate 403, and convey a wooden block between two adjacent fences 411. The container 401 inputs glue into the set 406 through the output pipe 409. The glue in the set 406 seeps out to the head of the brush 407 through the brush 407. The driving component 2 is started. The driving component 2 drives the second driven gear 408, the first rotating shaft 405, the set 406, the brush 407 and the first driven gear 303 to rotate. At the same time, the brush 407 applies glue to the side of the wooden block during the rotation process. The wooden block moves backward under the friction of the brush 407 and the rolling of the first roller 404.

[0060] Step 2: The first driven gear 303 drives the front roller 302, the conveyor chain 301 and the rear roller 305 to rotate, and the multiple wooden blocks coated with glue enter the conveyor chain 301, and the conveyor chain 301 drives the multiple wooden blocks coated with glue to move backward;

[0061] Step 3, one end of the plurality of wooden blocks contacts the rotating rod 506; the rotating rod 506 moves forward and compresses the spring 1 507, and determines whether the preset number of wooden blocks have moved to the rotating rod 506 according to the compression amount of the spring 1 507. If the preset number of wooden blocks have moved to the rotating rod 506, the motor 2 503 drives the rotating rod 506 to lift, the driving assembly 2 controls the conveyor chain 301 to stop running, and the motor 3 504 drives the second screw 505 to rotate, thereby driving the support block 5 514 to move and then driving the right guide rail 502 to move horizontally to the left, thereby pushing the plurality of wooden blocks to move horizontally and press them together;

[0062] Step 4: The driving component 2 drives the conveyor chain 301 to continue to operate. When the pressed wooden blocks move to the bottom of the protective panel 7, the driving component 2 controls the conveyor chain 301 to stop operating.

[0063] Step 5, start the hydraulic cylinder 604, the hydraulic cylinder 604 drives the support plate 603 to move downward, the support plate 603 drives the high-frequency machine 605, the pressurizing table 606 and the protective panel 7 to move downward, so that the protective panel 7 is in contact with the pressed wood blocks, start the high-frequency machine 605, and the high-frequency machine 605 transmits the high-frequency electromagnetic field to the pressed wood blocks through the pressurizing table 606 and the protective panel 7, so that the glue between the adjacent wood blocks is quickly cured;

[0064] Step 6. After curing is completed, a wooden board layer is formed, and the driving component 2 drives the conveyor chain belt 301 to continue to operate. When the wooden board layer passes through the humidifying nozzle 9 at the rear end of the support plate 603, the external water supply source transports water to the humidifying nozzle 9, and the humidifying nozzle 9 sprays water mist to humidify the wooden board layer. The conveyor chain belt 301 transports the humidified wooden board layer to the material receiving component 8, and the material is collected through the material receiving component 8.
