Description

Technical Field

[0001] This utility model relates to the technical field of furniture board production and processing, specifically to a hot pressing device for furniture boards. Background Technology

[0002] In the field of wood-based panel manufacturing, hot pressing equipment is the core equipment for producing engineered wood products such as fiberboard, particleboard, and plywood. Its technological development directly affects the density, strength, and environmental performance of these panels. Traditional hot pressing processes often use single-layer or multi-layer flatbed hot presses, which solidify the glued wood raw materials through heating and pressurization. However, this method suffers from high energy consumption, insufficient temperature and pressure control precision, and poor panel thickness uniformity. Early equipment relied on hydraulic or mechanical pressurization systems, with steam or electric heating as the primary heat source, easily leading to low thermal efficiency and defects such as heat spots on the panel surface. With increasingly stringent environmental standards and the growing application of composite materials, modern technologies are exploring improved solutions such as high-frequency preheating, continuous roller pressing, and segmented temperature control. Simultaneously, optimizations are being made to the parallelism of the pressing plates, closing speed, and cooling and shaping processes to adapt to the demands of new processes using formaldehyde-free adhesives and recycled materials. The key to this technology lies in balancing production efficiency and energy consumption while simultaneously meeting increasingly stringent standards for panel mechanical properties and formaldehyde emission. This places higher demands on the design of hot pressing temperature curves, pressure distribution uniformity, and automated control.

[0003] Application number CN202322449727.5 discloses a hot-pressing device suitable for furniture boards, including a base plate, symmetrically arranged crossbeams and mounting plates. The base plate has symmetrically opened positioning holes, and a support plate is fixedly mounted on its surface. First connecting rods are symmetrically mounted on both sides of the support plate, with first connecting rings fixedly mounted at their outer ends. Hydraulic cylinders are symmetrically mounted on the middle of both sides of the support plate, with piston rods mounted in the middle of each cylinder and clamping plates fixedly mounted at their ends. Airbags are fixedly mounted on the surface of the support plate, and air pumps are mounted on the sides of the support plate. A connecting rope connects the crossbeams and the base plate, and second connecting rods are symmetrically welded to the sides of the crossbeams. This invention can disperse the boards by controlling the airbags, and then control the spacing between the boards through a feed pipe, facilitating tight hot pressing. However, a drawback is that during hot pressing, boards whose bottoms are not accurately positioned may shift, posing a risk of misalignment during the hot pressing process. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is a hot pressing device for home furnishing boards, including a fixed support assembly 1, a pneumatic pressing assembly 4 installed on the top of the fixed support assembly 1, a material transfer assembly 2 installed on the top of the fixed support assembly 1, a hot pressing assembly 5 installed at the bottom of the pneumatic pressing assembly 4, and a positioning assembly 3 installed on the top of the material transfer assembly 2.

[0026] The positioning component 3 includes a positioning side plate 301, which is fixedly installed on both sides of the placement plate 204. A mounting side clamp 302 is fixedly installed in the middle of the rear side of the positioning side plate 301. A return spring 303 is installed in the middle of the mounting side clamp 302. Positioning clamps 304 are installed on both sides of the return spring 303.

[0027] By incorporating a positioning component 3 into the device, the wooden board to be hot-pressed can be fixed in place after placement using the device, making subsequent hot-pressing work more convenient and preventing deviation.

[0028] The fixed support assembly 1 includes a worktable 101, with fixed suction cups 102 fixedly installed diagonally on the bottom of the worktable 101, and a brake bracket 103 fixedly installed on the top of the worktable 101.

[0029] The material transfer assembly 2 includes a pneumatic telescopic rod 201. One end of the pneumatic telescopic rod 201 is mounted on the top rear side of the workbench 101 via a mounting hinge 202, and a connecting plate 203 is mounted on the end of the pneumatic telescopic rod 201. A placement plate 204 is connected to the top of the connecting plate 203. Movable sliders 205 are fixedly mounted on both sides of the bottom of the placement plate 204. The movable sliders 205 are slidably mounted on the top of the movable slide rail 206. The movable slide rail 206 is fixedly mounted on both ends of the top of the workbench 101. The pneumatic telescopic rod 201 pushes the connecting plate 203, causing the placement plate 204 to slide along the movable slide rail 206, conveying the plate directly below the hot pressing assembly 5. Due to the cooperation between the movable sliders 205 and the movable slide rail 206, the movement of the plate is smooth and precise.

[0030] The positioning clamp 304 is installed on both sides of the mounting clamp 302. The positioning side plate 301 and the positioning clamp 304 of the positioning component 3 automatically clamp the plate under the action of the return spring 303 to ensure that it will not shift during the pressing process.

[0031] The pneumatic pressing assembly 4 includes a pneumatic telescopic pump 401, which is mounted on the top of the brake bracket 103 via a bracket. A push rod 402 is mounted on the bottom of the pneumatic telescopic pump 401, and a pressing plate 403 is fixedly mounted on the bottom of the push rod 402. Slide rods 404 are fixedly mounted on both sides of the top of the pressing plate 403. The slide rods 404 slide through both sides of the top plate of the brake bracket 103. When the pneumatic telescopic pump 401 is activated, it pushes the push rod 402 downward, causing the pressing plate 403 and the hot pressing assembly 5 to press down. Under the guidance of the brake bracket 103, the slide rods 404 ensure the stability of the pressing process and avoid deviation.

[0032] The hot pressing assembly 5 includes a heat-conducting plate 501, which is installed at the bottom of the extrusion plate 403. A hot pressing plate 502 is fixedly installed at the bottom of the heat-conducting plate 501. The bottom of the hot pressing plate 502 is correspondingly positioned at the top of the placement plate 204. The heat-conducting plate 501 heats the hot pressing plate 502 to reach a set temperature. The hot pressing plate 502 comes into contact with the board material. Under the combined action of pressure and temperature, the board material, such as plywood or MDF, is hot-pressed and bonded or surface-coated.

[0033] This hot pressing device is mainly used for pressing and hot pressing of furniture boards. Its working principle can be divided into the following steps: First, the board to be processed is placed on the placement plate 204 of the material transfer component 2. The positioning side plate 301 and positioning clamp 304 of the positioning component 3 automatically clamp the board under the action of the return spring 303 to ensure that it will not shift during the pressing process. The pneumatic telescopic rod 201 pushes the connecting plate 203, so that the placement plate 204 slides along the moving slide rail 206, transporting the board to the bottom of the hot pressing component 5. Due to the cooperation between the moving slider 205 and the moving slide rail 206, the movement of the board is smooth and precise. The pneumatic telescopic pump 401 starts, pushing the push rod 402 downward, driving the extrusion plate 403 and the hot pressing component 5 to press down. Under the guidance of the brake bracket 103, the slide rod 404 ensures the stability of the pressing process and avoids deviation. The heat-conducting plate 501 heats the hot pressing. The hot press plate 502 is brought to a set temperature, and then contacts the board material. Under the combined action of pressure and temperature, the board material, such as plywood or MDF, is hot-pressed and bonded or surface-coated. After pressing, the pneumatic telescopic pump 401 retracts, driving the hot press assembly 5 to rise. The pneumatic telescopic rod 201 of the material transfer assembly 2 pulls back, causing the placement plate 204 to return to its initial position. The operator can then remove the processed board material. The positioning assembly 3 ensures that the board material does not shift during the pressing process, improving processing accuracy. The material transfer assembly 2 enables automatic feeding and retraction of the board material, reducing manual intervention. Pneumatic pressing combined with hot pressing technology improves pressing efficiency and quality. The design of the fixed support assembly 1 and the slide rod 404 ensures stable operation of the equipment and avoids vibration or misalignment. This device is suitable for furniture manufacturing, decorative board processing, and other fields, and can efficiently complete hot pressing, bonding, and coating processes for boards.
