Description

TECHNICAL FIELD

[0001] The present application relates to a bamboo-wood hot pressing device, in particular to a bamboo-wood composite board hot pressing device capable of realizing continuous production. BACKGROUND

[0002] For a long time, the board products for home use have relied on wood materials. Although wood is a renewable resource, the total amount is very limited, especially in areas with poor forest resources. China has abundant bamboo resources. Bamboo has the characteristics of fast regeneration, early maturity, high yield, and strong reproductive ability. The tensile and compressive strength of bamboo along the grain is extremely high, which can effectively replace part of the solid wood and has a significant effect on protecting forest resources. Bamboo-wood composite boards have a wide range of applications in daily life, such as bamboo chopping boards, bamboo furniture, and bamboo flooring. Based on the particularity of wood-based panels and bamboo, it is very meaningful to develop lightweight and high-strength bamboo-wood composite boards. The mainstream of the current market can be divided into two categories. One is fiberboard and particleboard. Although most of them have adopted continuous flat pressing machines for continuous production, high production efficiency, and high raw material utilization rate, the physical and mechanical properties are generally low, and the large-format panels used for furniture are prone to warping and deformation. The other is plywood and laminated material products. Although the physical and mechanical properties are good, the raw material utilization rate is low. Most of them still use manual lifting, gluing, and laying, and use intermittent single or multi-layer presses, which cannot realize continuous production, are time-consuming and labor-intensive, have low production efficiency, and cannot guarantee the quality. Therefore, it is difficult to solve the contradiction between high raw material utilization rate, light and high-strength board quality, and continuous and high-efficiency production. In order to solve the above problems, through retrieval, the Chinese patent with publication number CN215358897U discloses a lightweight and high-strength bamboo-wood laminated composite board continuous production device. The device includes two bamboo mat continuous impregnation mechanisms, a board conveying mechanism, a laying mechanism, a continuous hot pressing mechanism, and a sawing mechanism. The two bamboo mat continuous impregnation mechanisms are used for continuous impregnation of the upper and lower bamboo mat boards, respectively. The board conveying mechanism is used to place the core board gap on the lower bamboo mat board. The laying mechanism is arranged beside the board conveying mechanism and is used to lay the lower bamboo mat board, the core board, and the upper bamboo mat board into a board blank in layers. The above-mentioned device can realize continuous and efficient production. The continuous hot pressing mechanism is used to continuously hot press the board blank into a shape, which has high production efficiency and stable quality. The sawing mechanism saws the hot pressed board blank along the gap of the core board to obtain a finished board, realizing automatic and continuous production. However, in actual use, after the bamboo-wood laminated composite material is processed, it is hot pressed into a shape. When the mold is loosened, the board cannot be quickly cooled and shaped, and the risk of deformation is high. SUMMARY

The waiting time between each link is reduced, such as the time-consuming of stopping after feeding and transferring alone after hot pressing. The production cycle of a single product is greatly shortened, the output per unit time is improved, the processing precision is improved, and the product consistency is improved. 2. The present scheme can continuously feed through the wood feeding frame during the hot pressing of the bamboo-wood composite board. During the feeding process, manual intervention is not required. The operation continuity is strong. The piston rod of the driving cylinder drives the top plate to move horizontally. Under the action of the driving seat A and the driving seat B, the supporting table A and the supporting table B can alternately reciprocate up and down, ensuring the continuous performance of the wood supporting and releasing link, laying a foundation for the subsequent process.

The present scheme realizes the synchronous expansion and contraction of the first hot pressing sleeve and the second hot pressing sleeve through the driving cylinder and the reversing mechanism. The piston rod of the driving cylinder drives the second hot pressing sleeve to move horizontally. The piston rod of the driving cylinder can drive the first hot pressing sleeve to move horizontally through the reversing mechanism, realize the synchronous opposite movement of the first hot pressing sleeve and the second hot pressing sleeve, realize the opening and closing of the mold, and realize the efficient and centralized driving mode. Without additional driving devices, the structure of the overall driving system is greatly simplified, the complexity and manufacturing cost of the equipment are reduced, and the workload and difficulty of the later maintenance are also reduced. Secondly, the motion synchronization is accurate and reliable. 4. The present scheme realizes the connection and layout of the components through the cooperation of the driving cylinder and the reversing mechanism, which is more compact, saves the installation space of the equipment, is conducive to the arrangement of the equipment in the limited production site, improves the space utilization rate, and is provided with a plurality of heating strips in the first hot pressing sleeve and the second hot pressing sleeve. 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.
