Description

Technical Field

[0001] This invention relates to a bamboo and wood hot pressing device, and more particularly to a bamboo and wood composite board hot pressing device that enables continuous production. Background Technology

[0002] For a long time, wood-based panel products for home furnishings have relied heavily on wood materials. Although wood is a renewable resource, its total quantity is very limited, especially in areas with scarce forest resources. my country has abundant bamboo resources; bamboo regenerates quickly, matures early, has high yields and strong reproductive capacity, and possesses extremely high tensile and compressive strength along the grain, effectively replacing some solid wood and significantly contributing to forest resource protection. Bamboo-wood composite panels have wide applications in daily life, such as bamboo cutting boards, bamboo furniture, and bamboo flooring. Given the unique properties of wood-based panels and bamboo, developing lightweight, high-strength bamboo-wood composite panels is highly significant. Currently, mainstream engineered wood products on the market can be broadly categorized into… There are two main categories: fiberboard and particleboard. While most of these are now produced using continuous flatbed presses, resulting in high production efficiency and material utilization, their physical and mechanical properties are generally low, making them prone to warping and deformation when used for large furniture panels. The other category consists of plywood and laminated lumber. Although these have good physical and mechanical properties, their material utilization is low, and most still require manual lifting, gluing, and installation using intermittent single- or multi-layer presses. Continuous production is impossible, resulting in time-consuming, labor-intensive, and inefficient production, with inconsistent quality. Therefore, achieving both high material utilization, lightweight and high-strength boards, and continuous, high-efficiency production remains a difficult contradiction to resolve. To address the aforementioned issues, a search revealed Chinese patent CN215358897U, which discloses a continuous production device for lightweight, high-strength bamboo-wood laminated composite boards. The device includes two continuous bamboo mat impregnation mechanisms, a board handling mechanism, a laying mechanism, a continuous hot-pressing mechanism, and a sawing mechanism. The two continuous bamboo mat impregnation mechanisms are used for the continuous impregnation of the upper and lower bamboo mat boards, respectively. The board handling mechanism is used to place the core board gap onto the lower bamboo mat board. The laying mechanism is located next to the board handling mechanism and is used to lay the lower bamboo mat board, the core board, and the upper bamboo mat board in layers to form a board blank. Although the above-mentioned device can achieve continuous and efficient production, the continuous hot pressing mechanism is used to continuously hot press the blank into shape, resulting in high production efficiency and stable quality. The sawing mechanism saws the hot-pressed blank along the gap of the core board to obtain the finished board, realizing automated continuous production. However, in actual use, after the bamboo-wood laminated composite material is processed, because it is hot-pressed, the board cannot cool down and solidify quickly when the mold is released, resulting in a greater risk of deformation. Summary of the Invention

[0009] As an improvement to the above solution, the split hot pressing mechanism includes a first hot pressing sleeve, a second hot pressing sleeve, limiting columns, an L-shaped frame, a drive cylinder, and a reversing mechanism. The first and second hot pressing sleeves have the same length. The cross-section of the first hot pressing sleeve is U-shaped, and the cross-section of the second hot pressing sleeve is L-shaped. Semi-circular hot pressing grooves are opened inside both the first and second hot pressing sleeves.

A driven platform is fixedly provided at the end of the upper rack seat. The driven platform is fixedly connected to the back of the first hot press sleeve.

[0011] As an improvement to the above solution, the rotating support mechanism includes an inner support base, an output shaft, a stabilizing platform, and a telescopic rotating electric cylinder. The bottom of the stabilizing platform is screwed and fixed to the hot press platform, and a telescopic rotating electric cylinder is screwed and fixed to one side of the stabilizing platform.

The air expansion shaft expands to provide internal support for the wood and rotates it through the telescopic rotating electric cylinder. The rotating support mechanism is arranged opposite to the bamboo feeding mechanism.

[0012] As an improvement to the above solution, the bamboo feeding mechanism includes a stepping table, inner sockets, limiting plates, a cover plate, a transmission seat, a cylinder connecting seat, a guide table, a guide column, and a receiving port. The stepping table is cylindrical, and three sets of inner sockets are fixedly arranged at equal intervals on the outer circumference of the stepping table. Circular limiting plates are installed on the outer side of the inner sockets. Bamboo is installed inside each of the three sets of inner sockets. The bamboo is a ring structure composed of multiple bamboo strips. The bottom of the stepping table is connected to the transmission seat.

A cylinder connecting seat is installed on the front of the transmission seat, and the cylinder connecting seat is connected to the external cylinder piston rod.

[0013] As an improvement to the above solution, a supporting cooling mechanism is also included. The supporting cooling mechanism includes a support frame A, a support frame B, a mounting plate, a docking seat, a cooling fan, and a material drop channel. Three sets of support frames A and B are installed on both sides of the material drop channel. The support frames A and B are arranged in an inward V-shape. A docking seat is installed at the end of the mounting plate. The docking seat is screwed and fixed to the bottom surface of the hot press table. The length of the material drop channel is greater than the length of the wood. A split hot press mechanism, a bamboo feeding mechanism, and a rotating support mechanism are installed above the supporting cooling mechanism.

[0014] The present invention has the following advantages: 1. This solution utilizes a continuous process: a timber feeding frame feeds timber via an automatic feeding mechanism, a bamboo feeding mechanism feeds bamboo, a split-type hot pressing mechanism uses the first and second hot pressing sleeves to close and hot press, and the material is then directly released into the unloading channel after hot pressing. This reduces waiting time between each step, such as the time spent pausing after feeding or transferring the material separately after hot pressing. This significantly shortens the production cycle of a single product, increases output per unit time, and improves processing accuracy and product consistency. 2. This solution allows for continuous feeding of bamboo-wood composite boards during hot pressing using a timber feeding frame, eliminating the need for manual intervention. The operation is highly continuous; the piston rod of the drive cylinder drives the top plate laterally, and under the action of drive seats A and B, release platforms A and B can alternately rise and fall, ensuring continuous timber support and release, laying a solid foundation for subsequent processes. It also boasts a high degree of automation; the two sets of connecting plates on release platform B can automatically insert into the bottom box to support the timber, and can also automatically pull it out from the bottom box, allowing the timber to fall onto the split-type hot pressing mechanism in the open mold state. The entire process requires no manual intervention, reducing labor costs and improving operational efficiency. 3. This solution achieves the synchronous expansion and contraction of the first and second hot-pressing sleeves through a drive cylinder and a reversing mechanism. The piston rod of the drive cylinder drives the second hot-pressing sleeve to move laterally, while the piston rod of the drive cylinder can drive the first hot-pressing sleeve to move laterally through the reversing mechanism, realizing the synchronous opposite movement of the first and second hot-pressing sleeves, and realizing the mold opening and closing operation. The drive method is efficient and centralized; it eliminates the need for multiple additional drive devices, greatly simplifying the structure of the overall drive system, reducing the complexity and manufacturing cost of the equipment, and also reducing the workload and difficulty of later maintenance; secondly, the motion synchronization is precise and reliable. 4. This solution uses a combination of drive cylinder and reversing mechanism to make the connection and layout of each component more compact, saving equipment installation space and facilitating equipment layout in limited production areas, thus improving space utilization; multiple sets of heating strips are installed inside the first and second hot press sleeves. 5. This solution, through the combination of the semi-circular hot pressing grooves inside the first and second hot pressing sleeves, can precisely fit the shape of bamboo and wood, providing matching space for the hot pressing of the two and ensuring the fit of the processing; it is highly convenient to operate, and the heating strips on the first and second hot pressing sleeves can provide concentrated and uniform heat, tightly hot pressing the bamboo and wood together in the mold-closed state, ensuring a firm bond between the two and improving the structural strength and quality of the product; 6. This solution uses bamboo installed on the outside of three sets of inner sockets, allowing for simultaneous alternating feeding of the three sets of bamboo. After feeding, the inner socket can be rotated 120 degrees to insert new bamboo for later use, significantly improving feeding efficiency. The three sets of inner sockets evenly installed on the outside of the stepping table allow for simultaneous alternating feeding of the three sets of bamboo, avoiding the waiting gaps when feeding a single set, and continuously supplying material to the hot pressing space, significantly improving the overall processing rhythm and efficiency; feeding continuity is guaranteed. 7. In this solution, after the wood and bamboo are hot-pressed, they fall through the material drop channel onto the supporting cooling mechanism. Two sets of cooling fans on the supporting cooling mechanism dissipate heat from the product, allowing it to cool down and set quickly, reducing the risk of deformation. The two sets of cooling fans can quickly dissipate heat from the product, allowing it to cool down and set quickly, effectively reducing the risk of deformation caused by slow cooling, and ensuring the dimensional accuracy and appearance quality of the product.

[0034] The embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1

[0035] A hot-pressing device for continuous production of bamboo-wood composite panels, such as Figure 1-4 As shown, including The system includes a hot press table 6, with a supporting cooling mechanism 3 fixedly installed at its bottom. A wood feeding frame 1 is mounted on the surface of the hot press table 6 via a support frame. An automatic feeding mechanism 2 is installed at the bottom of the wood feeding frame 1. A split-type hot press mechanism 5 is installed below the wood feeding frame 1. A bamboo feeding mechanism 4 is installed on one side of the split-type hot press mechanism 5, and a rotating support mechanism 30 is installed on the other side. Wood 71 is placed inside the split-type hot press mechanism 5, and bamboo is fed... Bamboo material 7 is installed on the material feeding mechanism 4. A material dropping box 12 is fixedly installed at the bottom of the wood feeding frame 1. A feeding side plate 11 is fixedly installed on the outside of the wood feeding frame 1. The supporting cooling mechanism 3 includes a material dropping channel 36 opened in the middle of the hot press table 6. A support frame A31 is installed on one side of the bottom of the material dropping channel 36. A support frame B32 is installed on the other side of the bottom of the material dropping channel 36. An installation plate 33 is provided on one side of the support frame B32. Two sets of cooling fans 35 are fixedly installed on the installation plate 33.

[0036] Working Principle: In actual use, the wood feeding frame 1 contains a large number of layered wood pieces 71. The automatic feeding mechanism 2 can sequentially perform hot-pressing feeding via the wood feeding frame 1 and the automatic feeding mechanism 2. Simultaneously, the bamboo feeding mechanism 4 feeds the bamboo pieces 7 that need to be hot-pressed onto the outside of the wood pieces 71 into the split-type hot-pressing mechanism 5. At this time, the first hot-pressing sleeve 51 and the second hot-pressing sleeve 52 on the split-type hot-pressing mechanism 5 close, completing the hot-pressing of the wood pieces 71 and bamboo pieces 7. After hot-pressing, the wood pieces 71 and bamboo pieces 7 fall through the material drop channel 36 onto the supporting cooling mechanism 3, where two sets of cooling fans 35 dissipate heat. After the heat dissipation is complete, the material can be removed and then cut to a fixed length using the subsequent cutting device. During hot pressing of bamboo 7 and wood 71, feeding, hot pressing, and release are completed in one step. The wood feeding frame 1 is fed by the automatic feeding mechanism 2, the bamboo feeding mechanism 4 feeds bamboo 7, and the first and second hot pressing sleeves 51 and 52 of the split hot pressing mechanism 5 close for hot pressing. After hot pressing, the material is directly released into the discharge channel 36. This continuous process reduces waiting time between stages, such as the time spent pausing after feeding and transferring material separately after hot pressing, significantly shortening the production cycle of a single product and increasing output per unit time. It also improves processing accuracy and product consistency. From the wood 71, the material is positioned and fed from the wood feeding frame 1 via the automatic feeding mechanism 2 to the bamboo 71. 7. The bamboo material is precisely fed into the split-type hot pressing mechanism 5 via the bamboo feeding mechanism 4, and then the first hot pressing sleeve 51 and the second hot pressing sleeve 52 are closed for hot pressing. Throughout the process, the material remains in a stable positioning state, reducing deviations caused by multiple transfers and secondary positioning. The bonding position between the bamboo material 7 and the wood 71 is more precise, and the hot pressing pressure and temperature act more evenly within the first hot pressing sleeve 51 and the second hot pressing sleeve 52, resulting in more stable quality indicators such as dimensional accuracy and bonding strength of the final product. Energy consumption and production costs are reduced. The one-time completion of the process reduces the energy consumption of equipment idling or repeated starts: for example, the split-type hot pressing mechanism 5 does not need to maintain a heat preservation state while waiting for feeding, and the automatic feeding mechanism 2 and the bamboo feeding mechanism 4 also reduce the energy consumption of idle standby. At the same time, continuous operation reduces energy consumption. This reduces mechanical wear caused by repeated start-ups, shutdowns, and transfers in various mechanisms, thus reducing long-term equipment maintenance costs. It enhances automation adaptability, reduces manual intervention in feeding, and uses sensors to precisely control the rhythm of each stage, minimizing manual transfers and equipment starts, reducing human error, and saving labor costs, making it suitable for large-scale mass production. The short exposure time of wood 71 and bamboo 7 in the air during feeding, hot pressing, and release reduces problems such as moisture absorption, dehydration, and deformation of wood 71, and surface contamination of bamboo 7 caused by changes in ambient temperature and humidity, avoiding impacts on the curing effect of the adhesive or the stability of the materials themselves during hot pressing. After hot pressing, the material directly passes through the discharge channel 36 to the supporting cooling mechanism 3, where it is rapidly cooled by the cooling fan 35, further ensuring product shaping quality.Optimize production space utilization. The wood feeding frame 1, automatic feeding mechanism 2, bamboo feeding mechanism 4, split hot pressing mechanism 5, material drop channel 36 and support cooling mechanism 3 can achieve a compact layout due to the continuous process, reducing the space occupied by the scattered placement of each piece of equipment, which is especially suitable for production scenarios with limited workshop space. like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: The feeding side plates 11 at both ends of the timber feeding frame 1 have a "U" shaped cross section, and the bottom box 12 at the bottom of the timber feeding frame 1 has a rectangular cross section.

[0043] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown: The bamboo feeding mechanism 4 includes a stepping table 41, inner sockets 42, limiting plates 43, a cover plate 44, a transmission seat 45, a cylinder connecting seat 46, a guide table 47, a guide column 48, and a receiving port 49.

[0044] When the timber feeding frame 1 is in use, a large amount of timber 71 is stacked in layers inside the feeding side plate 11 of the timber feeding frame 1. The external switch of the drive cylinder 22 is activated, and the piston rod of the drive cylinder 22 drives the top plate 23 to move laterally. Under the action of the drive seats A24 and B25, the release support platforms A27 and B28 alternately reciprocate. When the two sets of connecting plates 276 on the release support platform B28 are inserted into the bottom box 12, they can support the timber 71. Simultaneously, when the two sets of connecting plates 276 on the release support platform B28 are withdrawn from the bottom of the bottom box 12... When the wood 71 loses its supporting structure, it falls onto the split hot pressing mechanism 5, which is in the open mold state, preparing for the first hot pressing sleeve 51 and the second hot pressing sleeve 52 to hot press the bamboo 7 and wood 71. During the hot pressing of the bamboo-wood composite board, the wood feeding frame 1 can continuously feed the material without manual intervention. The operation is highly continuous. The piston rod of the drive cylinder 22 drives the top plate 23 to move laterally. Under the action of the drive seat A24 and drive seat B25, the release platform A27 and release platform B28 can alternately reciprocate, ensuring the continuous operation of the support and release of the wood 71, laying a continuous foundation for subsequent processes. With a high degree of automation, the two sets of connecting plates 276 on the support platform B28 can automatically insert into the bottom box 12 to support the wood 71, and can also automatically pull out from the bottom of the bottom box 12 to let the wood 71 fall onto the split hot pressing mechanism 5 in the mold opening state. The whole process does not require manual intervention, reducing labor costs and improving work efficiency.The process flow is smooth. Wood 71 falls precisely into the split-type hot pressing mechanism 5 through the aforementioned automatic process, directly preparing for the hot pressing of bamboo 7 and wood 71 by the first hot pressing sleeve 51 and the second hot pressing sleeve 52. This ensures a tight connection between feeding and hot pressing, reducing intermediate waiting time and enabling uninterrupted feeding. During the hot pressing of bamboo-wood composite panels, the wood feeding frame 1 ensures uninterrupted feeding, guaranteeing continuous hot pressing and further improving overall production efficiency. The alternating movement of the release support platform A27 and release support platform B28 is as follows: when the top plate 23 moves laterally, it drives the drive seats A24 and B25 to move laterally, driving... When seat A24 moves forward, the inclined surface on drive seat A24 presses down on the driven wheel 272 at the top of release platform A27, causing release platform A27 to move downward. The two sets of connecting plates 276 at the bottom of release platform A27 are inserted into the inside of the material dropping box 12, supporting the wood 71 inside the material dropping box 12. At the same time, drive seat B25 moves forward, and the inclined surface on drive seat B25 exerts force on the driven wheel 272 at the top of drive seat B25, causing release platform B28 to move upward. The two sets of connecting plates 276 at the bottom of release platform B28 are pulled out from the inside of the material dropping box 12, releasing the wood 71, which falls freely into the split hot pressing mechanism 5 for hot pressing. When the split-type hot pressing mechanism 5 is in operation, the first hot pressing sleeve 51 and the second hot pressing sleeve 52 are initially in an unfolded state. The synchronous unfolding and retraction of the first hot pressing sleeve 51 and the second hot pressing sleeve 52 are both achieved through the drive cylinder 55 and the reversing mechanism 56. The piston rod of the drive cylinder 55 drives the second hot pressing sleeve 52 to move laterally, and at the same time, the piston rod of the drive cylinder 55 can drive the first hot pressing sleeve 51 to move laterally through the reversing mechanism 56, realizing the synchronous opposite movement of the first hot pressing sleeve 51 and the second hot pressing sleeve 52, realizing the mold opening and closing operation; the driving method is efficient and centralized; the synchronous unfolding and retraction of the first hot pressing sleeve 51 and the second hot pressing sleeve 52 only requires... This is achieved through the drive cylinder 55 and the reversing mechanism 56, eliminating the need for multiple additional drive units, greatly simplifying the overall drive system structure, reducing equipment complexity and manufacturing costs, and also reducing the workload and difficulty of later maintenance. Secondly, the motion synchronization is precise and reliable; while the piston rod of the drive cylinder 55 drives the second hot-pressing sleeve 52 to move laterally, the reversing mechanism 56 simultaneously drives the first hot-pressing sleeve 51 to move laterally, strictly ensuring the synchronous, opposite-direction movement of the first and second hot-pressing sleeves 51. This precise synchronization ensures consistency in mold opening and closing operations, avoiding processing errors caused by asynchronous movements, and effectively improving... This improves the precision of hot pressing and the stability of product quality; furthermore, it enhances work efficiency; due to the centralized drive and synchronous motion design, the mold opening and closing actions of the split hot pressing mechanism 5 are smooth and continuous, reducing unnecessary action delays and waiting time, and enabling more processing cycles to be completed per unit time, thereby significantly improving overall work efficiency and meeting the needs of mass production; in addition, the structural layout is compact and reasonable; the cooperative drive method of the drive cylinder 55 and the reversing mechanism 56 makes the connection and layout between various components more compact, saving equipment installation space, which is conducive to equipment layout in limited production sites and improving space utilization. Both the first hot pressing sleeve 51 and the second hot pressing sleeve 52 are equipped with multiple sets of heating strips 57, using high-frequency heating to ensure uniform heating of the bamboo 7 and wood 71 wrapped together. The first hot pressing sleeve 51 moves as follows: the transmission table 560 moves laterally under the drive of the output shaft of the drive cylinder 55, the transmission table 560 drives the lower rack seat 561 to move laterally, the lower rack seat 561 drives the reversing gear 564 to rotate, the reversing gear 564 simultaneously drives the upper rack seat 565 to move laterally, and the upper rack seat 565 drives the first hot pressing sleeve 51 to move, so that the first hot pressing sleeve 51 and the second hot pressing sleeve 52 move synchronously towards each other.The first hot-pressing sleeve 51 has a U-shaped cross-section, and the second hot-pressing sleeve 52 has an L-shaped cross-section. Both the first and second hot-pressing sleeves 51 and 52 have semi-circular hot-pressing grooves inside. Together, they form a hot-pressing space for the bamboo 7 and wood 71. After the wood 71 is placed inside the hot-pressing space, it is supported by a rotating support mechanism 30. The upper end of the rotating support mechanism 30 has an air shaft inserted into the hollow wood, allowing it to be suspended in mid-air. Simultaneously, the bamboo feeding mechanism 4 moves and transports the bamboo 7 into the hot-pressing space, where it is fitted onto the outside of the bamboo 7. Then, the first and second hot-pressing sleeves 51 and 52 close, the rotating support mechanism 30 is removed, and the heating strips 57 on the first and second hot-pressing sleeves 51 and 52 are used to heat the bamboo... 7. The wood 71 is hot-pressed together. The semi-circular hot-pressing grooves inside the first hot-pressing sleeve 51 and the second hot-pressing sleeve 52 can precisely fit the shape of the bamboo 7 and the wood 71, providing a matching space for the hot-pressing combination of the two and ensuring the fit of the processing. The operation is highly convenient. The air expansion shaft of the rotating support mechanism 30 is inserted into the hollow wood 71, which can stably support the wood 71 and suspend it in the air, making it easy for the bamboo feeding mechanism 4 to accurately transport the bamboo 7 to the hot-pressing space and fit it on the outside. The entire feeding process is orderly and convenient. The rotating support mechanism 30 is removed before the mold is closed to avoid interference with the hot-pressing process. The hot-pressing effect is excellent. The heating strips 57 on the first hot-pressing sleeve 51 and the second hot-pressing sleeve 52 can provide heat in a concentrated and uniform manner, and tightly hot-press the bamboo 7 and the wood 71 together in the mold-closed state, ensuring that the two are firmly bonded and improving the structural strength and quality of the product. When the bamboo feeding mechanism 4 conveys the bamboo 7, three sets of inner sockets 42 are evenly installed on the outer side of the stepping table 41 on the bamboo feeding mechanism 4. Bamboo 7 is installed on the outer side of each of the three sets of inner sockets 42, which can simultaneously realize the alternating feeding of the three sets of bamboo 7. After feeding, the inner socket 42 is rotated 120 degrees, and a new bamboo 7 can be inserted into the inner socket 42 for later use. The transmission base 45 is equipped with a motor device, and the output shaft of the motor device is connected to the stepping table 41, which can drive the stepping table 41 to rotate step by step. The feeding efficiency is greatly improved. The three sets of inner sockets 42 evenly installed on the outer side of the stepping table 41 can realize the alternating feeding of the three sets of bamboo 7 at the same time, avoiding the waiting time when feeding a single set. The gap allows for continuous material supply to the hot pressing space, significantly improving the overall processing rhythm and efficiency. Material feeding continuity is guaranteed; after feeding, the inner socket 42 can be rotated 120 degrees to re-insert new bamboo material 7 for later use. The entire material changing process is convenient and fast, without interrupting the hot pressing mechanism's workflow, ensuring production continuity and reducing downtime caused by untimely material replenishment. Operation is convenient and labor-saving; this alternating switching and rotation design ensures orderly connection between feeding and preparation actions, eliminating the need for frequent complex adjustments by operators, reducing operational intensity, and minimizing the impact of human error on production. The inner socket 42 can be replaced with an air shaft, improving the stability of the connection to the bamboo material 7 and preventing it from falling off. Example 2

[0045] Based on Example 1, such as Figure 6 and Figure 8 As shown: It also includes a support and cooling mechanism 3, which includes a support frame A31, a support frame B32, a mounting plate 33, a docking seat 34, a cooling fan 35, and a material drop channel 36. Three sets of support frames A31 and support frames B32 are installed on both sides of the material drop channel 36. The support frames A31 and support frames B32 are arranged in an inward V-shape. The mounting plate 33 is equipped with a docking seat 34 at its end. The docking seat 34 is screwed and fixed to the bottom surface of the hot press table 6. The length of the material drop channel 36 is greater than the length of the wood 71. A split hot press mechanism 5, a bamboo feeding mechanism 4, and a rotating support mechanism 30 are installed above the support and cooling mechanism 3.

[0046] After the wood 71 and bamboo 7 are hot-pressed, they fall through the material drop channel 36 onto the supporting cooling mechanism 3. Two sets of cooling fans 35 on the supporting cooling mechanism 3 dissipate heat from the product, allowing it to cool down and set quickly, reducing the risk of deformation. The three sets of support frames A31 and B32 on both sides of the material drop channel 36 are arranged in an inward V-shape, providing good guidance and limiting for the falling product, preventing it from shifting or getting stuck during descent. Furthermore, the length of the material drop channel 36 is greater than the length of the wood 71, adapting to the product size and ensuring a stable and orderly material drop process. The installation is secure and reliable; the mating seat 34 at the end of the mounting plate 33 is screwed to the bottom surface of the hot press table 6. The structure is robust, providing stable support for the material drop channel 36 and ensuring its stability during long-term use. It also features a high degree of integration, with a split-type hot pressing mechanism 5, bamboo feeding mechanism 4, and rotating support mechanism 30 centrally installed above the cooling support mechanism 3. The compact layout of these mechanisms forms a continuous production process, reducing the transfer time and distance between processes and improving overall production efficiency. Furthermore, it ensures higher product quality. After the hot-pressed wood 71 and bamboo 7 fall through the material drop channel 36 to the cooling support mechanism 3, two sets of cooling fans 35 quickly dissipate heat, rapidly cooling and shaping the product. This effectively reduces the risk of deformation due to slow cooling, ensuring the product's dimensional accuracy and appearance quality.
