Technical Field
[0001] This utility model relates to the field of wood flooring processing technology, specifically to a three-layer solid wood flooring blank forming device. Background Technology
[0002] Multi-layer solid wood flooring is a composite flooring made of multiple layers of wood veneers arranged in a crisscross pattern as the base material, with precious wood veneers glued to the surface, and then hot-pressed with adhesive. The processing of multi-layer solid wood flooring requires applying glue and hot-pressing. Currently, the method used is to apply glue to the multi-layer boards and then hot-press them. Concentrated hot pressing can easily cause air bubbles, resulting in weak adhesion and affecting the quality of the solid wood flooring.
[0003] A multi-layer solid wood flooring blank forming device, with announcement number CN208247081U, includes a support column, a base, a support frame, and an air pump. The base is located at the lower end of the support column, the support frame is located on one side of the support column, and the air pump is mounted on the support frame. A worktable is located at the upper end of the support column, a push plate cylinder is located at one end of the worktable, a push plate is located at one end of the push plate cylinder, a moving plate is located at one end of the push plate, a sliding block is located below the moving plate, a guide rail is located below the sliding block, and limit baffles are located at both ends of the guide rail. An upper support is located on the worktable. The advantages are: This utility model mainly targets the processing of multi-layer solid wood flooring, performing separate gluing and hot pressing between individual layers to avoid the problem of weak adhesion during overall hot pressing, ensuring the processing quality of multi-layer solid wood flooring. The device has a simple overall structure and is easy to operate.
[0004] The aforementioned device avoids the problem of weak adhesion during overall hot pressing by applying glue and hot pressing separately between individual layers, ensuring the processing quality of multi-layer solid wood flooring. The device has a simple overall structure and is easy to operate. However, when hot pressing the boards after splicing them together, the device lacks corresponding limiting measures between the boards. Uneven pressure can easily cause misalignment or slippage between the boards, resulting in structural delamination or weak adhesion, affecting the stress release function of the boards. Furthermore, glue overflow or thickness deviation is prone to occur at the edges of the boards, thus affecting the flatness, bonding strength, and service life of the finished flooring. At the same time, the boards generate volatile organic compounds, formaldehyde, and harmful dust during hot pressing, affecting the safety of the production environment. Therefore, those skilled in the art provide a three-layer solid wood flooring board forming device to solve the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please see Figures 1-7 This utility model provides a technical solution: a three-layer solid wood flooring blank forming device, including a support frame 1 and a mounting frame 2. The mounting frame 2 is fixedly connected to the upper end face of the support frame 1. A placement component 3 for placing the blank is installed on the upper end of the support frame 1. A gluing device 4 for applying glue is installed on one side of the upper end of the mounting frame 2. A forming component 5 for hot pressing is installed on one side of the upper end of the mounting frame 2. A limiting component 6 for limiting the blank is installed inside the placement component 3. A purification component 7 for absorbing gas is installed on one side of the upper end of the mounting frame 2. A wood board blank 10 is installed inside the placement component 3.
[0026] Furthermore, by placing the first layer of wood board blank 10 to be processed inside the placement component 3, the placement component 3 then moves the wood board blank 10 to below the gluing device 4, allowing the gluing device 4 to apply glue to the upper surface of the first layer of wood board blank 10. After gluing, the placement component 3 moves the wood board blank 10 to below the forming component 5. At this point, the user aligns the second layer of wood board blank 10 with and adheres it to the upper surface of the first layer of wood board blank 10. Subsequently, the forming device descends to perform hot pressing on the second layer of wood board blank 10. During the hot pressing process, the limiting component 6 rises to limit the second layer of wood board blank 10, effectively preventing large misalignment or displacement of the wood board blank 10 during hot pressing, ensuring interlayer alignment, and reducing problems such as uneven bonding and density delamination caused by displacement. This process improves the structural strength, dimensional stability, and surface flatness of the product, ensuring product quality. After hot pressing, the forming component 5 resets, and the limiting component 6 automatically resets. The automatically lifting limiting component 6 synchronizes with the lifting action of the forming component 5, reducing manual intervention time. After hot pressing, the limiting component 6 automatically retracts, avoiding the hassle of manually prying the wooden board blank 10, reducing the risk of edge damage to the board, and freeing up operating space for more convenient and efficient material handling. The above operation is repeated to apply glue and hot press the third layer of wooden board blank 10. During the hot pressing process, the purification component 7 absorbs and purifies the gas in the hot pressing area, thereby adsorbing volatile organic compounds, formaldehyde, and harmful dust released during the hot pressing process, ensuring a safe production environment and environmentally friendly products.
[0027] It is worth noting that the glue application device 4 is existing technology. The glue application device 4 mainly consists of a glue tank, a scraper, a coating roller, a transmission device and a glue circulation device. Its working principle is to transfer the adhesive in the glue tank evenly to the surface of the wood board blank 10 through the cooperation of the coating roller and the metering roller, so as to ensure that the glue fully penetrates the wood fiber pores and provides a uniform and reliable bonding interface for subsequent hot pressing molding. This will not be elaborated here.
[0028] As one implementation method in this embodiment, please refer to Figure 3 As shown, the placement component 3 includes two guide rails 301, a placement box 302, a placement groove 303, and a first cylinder 304. The two guide rails 301 are fixedly connected to the upper center of the support frame 1. The placement box 302 is slidably sleeved on the outside of the two guide rails 301. The placement groove 303 is opened at the upper center of the placement box 302. The first cylinder 304 is fixedly installed on the lower side of the mounting frame 2. The output end of the first cylinder 304 passes through the mounting frame 2 and is fixedly connected to the center of the side wall of the placement box 302. The wooden board blank 10 is placed in the placement groove 303. The inner contour of the placement groove 303 matches the outer contour of the wooden board blank 10.
[0029] Furthermore, by placing the first layer of wood board blank 10 to be processed into the placement groove 303, the first cylinder 304 drives the placement box 302 to move. When the placement box 302 contacts the first pressure sensor 8, it indicates that the wood board blank 10 in the placement groove 303 has moved to below the glue application device 4. The glue application device 4 applies glue to the upper surface of the first layer of wood board blank 10. After the glue application is completed, the first cylinder 304 drives the placement box 302 to move. After the placement box 302 contacts the second pressure sensor 9, the wood board blank 10 moves directly below the hot press plate body 503.
[0030] As one implementation method in this embodiment, please refer to Figure 4 As shown, the molding component 5 includes a second cylinder 501, a mounting plate 502 and a hot press plate body 503. The second cylinder 501 is fixedly installed on one side of the upper end of the mounting frame 2. The output end of the second cylinder 501 passes through the mounting frame 2. The mounting plate 502 is fixedly connected to the output end of the second cylinder 501. The hot press plate body 503 is fixedly installed on the lower end of the mounting plate 502.
[0031] Furthermore, the user aligns the second layer of wooden board blank 10 with the upper surface of the first layer of wooden board blank 10. At this time, the second cylinder 501 drives the hot press plate body 503 to descend until the hot press plate body 503 contacts the top of the second layer of wooden board blank 10, thereby realizing the hot pressing forming of the first layer of wooden board blank 10 and the second layer of wooden board blank 10. The hot press plate body 503 is a prior art technology. The hot press plate is heated to the set temperature by electric heating or heat transfer oil circulation system. Under the drive of the second cylinder 501, uniform pressure is applied to the stacked blanks, so that the adhesive in the blanks melts and flows and penetrates the fibers. At the same time, the heat promotes the resin curing, and finally the fibers cross-link and cure to form a dense and flat finished floor product. It will not be elaborated here. The outer contour of the hot press plate body 503 matches the outer contour of the wooden board blank 10.
[0032] As one implementation method in this embodiment, please refer to Figures 5-6As shown, the limiting component 6 includes a lifting groove 601, two lifting ports 602, two upright plates 605, and two second racks 607. The lifting groove 601 is located at the upper end of the placement box 302. The two lifting ports 602 are respectively located on the inner walls of both sides of the lifting groove 601, extending to the outside and communicating with the outside. A limiting plate 603 is slidably connected inside the lifting groove 601. A first rack 604 is slidably connected inside each of the two lifting ports 602. The two first racks 604 are fixedly connected to the lower side wall of the limiting plate 603. The two upright plates 605 are respectively fixedly connected to both sides of the placement box 302. A spur gear 606 is rotatably connected to the side of each upright plate 605 near the first rack 604. The two spur gears 606 mesh with the upper teeth of the two first racks 604. The two second racks 607 are respectively fixedly connected to both sides of the mounting plate 502, and the two second racks 607 mesh with the two spur gears 606.
[0033] Furthermore, during the descent of the hot press plate body 503, the second rack 607 descends along with the mounting plate 502. During this descent, the second rack 607 meshes with the spur gear 606. As the spur gear 606 rotates, the first rack 604 slides upward through the lifting port 602, causing the limiting plate 603 to slide out of the lifting groove 601. The limiting plate 603 then limits the second layer of wood board blank 10, effectively preventing significant misalignment or displacement of the second layer of wood board blank 10 during hot pressing, ensuring layer alignment, and reducing problems such as uneven bonding and density delamination caused by displacement, thereby improving… The structural strength, dimensional stability, and surface flatness of the product ensure product quality. After hot pressing, the second cylinder 501 drives the mounting plate 502 to rise and reset. Similarly, the limit plate 603 automatically descends. The automatically rising and falling limit plate 603 achieves synchronous rising and falling with the hot pressing plate body 503, reducing manual intervention time. After hot pressing, the limit component 6 automatically retracts, which avoids the trouble of manually prying the wooden board blank 10, reduces the risk of edge damage to the board, and frees up operating space, making material handling more convenient and efficient. At this time, the above operation is repeated to apply glue and hot press the third layer of wooden board blank 10.
[0034] It is worth noting that when the third layer of wood panel blank 10 is hot-pressed, the second rack 607 rises to near the center of the lifting port 602. At this time, the limiting plate 603 rises to near the center of the third layer of wood panel blank 10. When the second layer of wood panel blank 10 is hot-pressed, the second rack 607 rises to near the top wall of the lifting port 602, meaning the limiting plate 603 rises to a height higher than the aforementioned height of the third layer of wood panel blank 10. Therefore, when the second and third layers of wood panel blank 10 are hot-pressed, the limiting plate 603 can stably limit the movement of both layers. The spacer plate 603 is positioned at a certain distance from the wooden board blank 10. This serves two purposes: firstly, it prevents the limiting plate 603 from contacting the wooden board blank 10 during lifting and lowering; secondly, the wooden board blank 10 expands or contracts due to heat during hot pressing, and the reserved distance provides a buffer space to prevent stress concentration or edge cracking of the wooden board blank 10 caused by thermal deformation. It also allows the heat generated during hot pressing to escape from the gap. Furthermore, the limiting plate 603 is larger than the hot pressing plate body 503, preventing the limiting plate 603 from contacting the hot pressing plate body 503 during hot pressing. Additionally, the limiting plate 603 has an opening that matches the guide rail 301, ensuring that the limiting plate 603 does not affect the sliding of the placement box 302 on the surface of the guide rail 301.
[0035] As one implementation method in this embodiment, please refer to Figure 7 As shown, the purification assembly 7 includes a purification box 701, an exhaust fan 702, an air supply pipe 703, multiple activated carbon plates 704, and a gas collection hood 705. The purification box 701 is fixedly connected to the upper end of the mounting bracket 2. The exhaust fan 702 is fixedly installed on the side of the purification box 701 away from the second cylinder 501. The output end of the exhaust fan 702 is connected to the inside of the purification box 701. The output end of the air supply pipe 703 is fixedly connected to the input end of the exhaust fan 702. The airflow outlets of the multiple gas collection hoods 705 are fixedly connected to the input end of the side wall of the air supply pipe 703. The airflow inlets of the multiple gas collection hoods 705 are all facing the hot press plate body 503. The activated carbon plates 704 penetrate the side wall of the purification box 701 and are disposed inside the purification box 701. The activated carbon plates 704 slide through the side wall of the purification box 701 in a retractable manner. When the activated carbon plates 704 are moved out of the purification box 701 in the retractable direction, they are completely exposed to the external environment for replacement.
[0036] Furthermore, during the hot pressing process, the exhaust fan 702 in the purification component 7 starts working, and absorbs the gas from the hot pressing area into the purification box 701 through the gas collection hood 705. The gas is then adsorbed and purified by the activated carbon plate 704, thereby adsorbing volatile organic compounds, formaldehyde and dust harmful substances released during the hot pressing process, ensuring the safety of the production environment and the environmental friendliness of the products. The side wall of the purification box 701 is connected to an exhaust pipe for discharging the purified gas.
[0037] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a first pressure sensor 8 is fixedly installed on the lower part of the inner wall of the mounting bracket 2 near the adhesive applicator 4, and a second pressure sensor 9 is fixedly installed on the lower part of the inner wall of the mounting bracket 2 away from the first pressure sensor 8.
[0038] Furthermore, both the first pressure sensor 8 and the second pressure sensor 9 are existing technologies. Their working principle is to convert the pressure signal applied from the outside into a measurable electrical signal through a sensitive element. When pressure is applied to the sensor, it causes a change in the physical characteristics of the sensitive element. After being processed by the signal conditioning circuit, an electrical signal proportional to the pressure is finally output, thereby achieving accurate measurement and monitoring of the pressure. Therefore, when the placement box 302 comes into contact with the first pressure sensor 8, it transmits a signal, that is, it detects that the wooden board blank 10 in the placement groove 303 has moved to below the glue applicator 4. After the placement box 302 comes into contact with the second pressure sensor 9, it detects that the wooden board blank 10 has moved to directly below the hot press plate body 503. This will not be elaborated further here.
[0039] Working principle: The first layer of wood board blank 10 to be processed is placed in the placement groove 303. Then, the first cylinder 304 drives the placement box 302 to move. When the placement box 302 contacts the first pressure sensor 8, it indicates that the wood board blank 10 in the placement groove 303 has moved below the gluing device 4. The gluing device 4 applies glue to the upper surface of the first layer of wood board blank 10. After the glue application is completed, the first cylinder 304 drives the placement box 302 to move. After the placement box 302 contacts the second pressure sensor 9, the wood board blank 10 moves directly below the hot press plate body 503. The user then places the second layer of wood board blank 10. Aligning with the upper surface of the first layer of wooden board blank 10, the second cylinder 501 drives the hot press plate body 503 to descend until it contacts the upper surface of the second layer of wooden board blank 10, thereby achieving hot pressing forming of the first and second layer of wooden board blank 10. During the descent of the hot press plate body 503, the second rack 607 descends with the mounting plate 502. During the descent, the second rack 607 meshes with the spur gear 606. As the spur gear 606 rotates, the first rack 604 slides upward in the lifting port 602, thereby causing the limiting plate 603 to slide out of the lifting groove 601. The positioning plate 603 can limit the second layer of wood board blank 10, effectively preventing large misalignment or displacement of the second layer of wood board blank 10 during hot pressing, ensuring interlayer alignment, reducing problems such as uneven bonding and density delamination caused by displacement, thereby improving the structural strength, dimensional stability and surface flatness of the product, and ensuring product quality. After hot pressing is completed, the second cylinder 501 drives the mounting plate 502 to rise and reset. Similarly, the positioning plate 603 automatically descends. The automatically rising and falling positioning plate 603 achieves synchronous rising and falling with the rising and falling action of the hot pressing plate body 503, reducing manual intervention time. After hot pressing is completed, the positioning plate 603 automatically descends. The automatic retraction of component 6 avoids the hassle of manually prying the wooden board blank 10, reduces the risk of edge damage to the board, and frees up operating space, making material handling more convenient and efficient. At this time, the above operation is repeated to apply glue and hot press the third layer of wooden board blank 10. During the hot pressing process, the exhaust fan 702 in the purification component 7 starts to work, and absorbs the gas in the hot pressing area into the purification box 701 through the gas collection hood 705. The activated carbon plate 704 adsorbs and purifies the gas, thereby adsorbing the volatile organic compounds, formaldehyde and dust harmful substances released during the hot pressing process, ensuring the safety of the production environment and the environmental friendliness of the products.
[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
