Description

Technical Field

[0001] The utility model relates to the technical field of solid wood board processing devices, in particular to a solid wood board hot pressing device. Background Art

[0002] Solid wood panel hot pressing equipment, also known as a hot press or wood hot press, is primarily used for hot pressing wood. It works by heating the wood to vaporize the moisture within it. Then, through high pressure, the wood becomes denser, increasing its hardness and strength. This can improve the hardness and strength of the wood in a short period of time. The treated wood has excellent waterproof, anti-corrosion, and termite-resistant properties, making it suitable for use in furniture, building materials, and other fields.

[0003] For example, the Chinese patent application "Hot Pressing Equipment for Plates," with publication number CN218947953U, includes a base and a top plate mounted on the base, a connecting frame mounted on the top plate, a second hydraulic telescopic rod mounted on the connecting frame, a hot pressing plate mounted on the output end of the second hydraulic telescopic rod, a support plate symmetrically mounted on the top of the top plate, a pneumatic telescopic rod mounted on the support plate, and a first limit plate mounted on the output end of the pneumatic telescopic rod. The pneumatic telescopic rod and the first limit plate can be used to limit the positions of the two ends of the plate, and a second motor can be used to drive the first and second screw rods to rotate, thereby driving the second limit plate to move.

[0004] Although the above-mentioned existing technology can realize hot pressing treatment of solid wood boards, the limiting structure of the boards requires the upper pressing plate to be adapted to the limiting plate, otherwise the two are likely to conflict with each other. In addition, under the obstruction of the limiting plate, it is also inconvenient to take the boards after pressing. Therefore, it does not meet the existing needs. In this regard, we propose a hot pressing device for solid wood boards. Utility Model Content

[0005] The purpose of the present invention is to provide a hot pressing device for solid wood panels to solve the problems of poor limiting effect of the hot pressing device on the panels and inconvenience in taking them after processing proposed in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for hot pressing solid wood panels, comprising a base, a housing welded and fixed to the outer edge of the upper end of the base, a hydraulic lifting device installed at a middle position of the upper end surface of the housing, and a movable end of the hydraulic lifting device extending into the interior of the housing, a lifting plate fixedly installed at one end of the hydraulic lifting device located inside the housing, and a pressing plate fixedly installed at the bottom of the lifting plate; and further comprising:

[0007] The pressing table is arranged at the middle position of the upper end face of the base. Screws are installed around the inside of the pressing table, and the screws are rotatably connected to the pressing table. A sliding block is installed on the outside of the screws, and the sliding block is threadedly connected to the screws;

[0008] The fixed baffle is arranged around the upper end face of the pressing table, and the bottom of the fixed baffle is fixed to the sliding block. A movable baffle is installed inside the fixed baffle, and the fixed baffle is slidably connected to the movable baffle.

[0009] Preferably, a servo motor is fixedly installed inside the base. A driving bevel gear is installed on the output shaft of the servo motor. Driven bevel gears are installed meshing around the driving bevel gear, and the shaft at one end of the driven bevel gear is fixed to the screw at the corresponding position.

[0010] Preferably, limiting grooves are arranged on both sides of the inner cavity of the fixed baffle. Limiting blocks are arranged on both sides of the movable baffle, and the limiting blocks are slidably limited in the limiting grooves. Springs are fixedly installed between the limiting grooves and the limiting blocks.

[0011] Preferably, the inner walls of the fixed baffle and the movable baffle are both on the same vertical plane.

[0012] Preferably, negative pressure suction cups are installed in the grooves at the four corners of the bottom of the pressing plate. The negative pressure suction cups are connected to the grooves at the bottom of the pressing plate through telescopic pipes equipped with support springs. A vacuum pump is fixedly installed on one side of the upper end face of the housing. The negative pressure end of the vacuum pump is installed with an air pipe, and the other end of the air pipe is hermetically connected to the telescopic pipe above the negative pressure suction cup.

[0013] Preferably, heating wires are installed at the lower end inside the pressing plate.

[0014] Preferably, the height of the fixed baffle is lower than the upper end face of the solid wood board.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The utility model adopts a flexible limiting structure. By turning on the servo motor, its output shaft drives the driving bevel gear to rotate. Under the meshing with the driven bevel gear, the screw rod is driven to rotate. Thread friction occurs between the screw rod and the sliding block, converting the rotational motion into linear motion. Thus, the fixed baffle is driven by the sliding block to move in the opposite direction of the solid wood board. With the cooperation of the four fixed baffles, pre-positioning of the board is achieved. The movable baffle can be higher than the upper end face of the board under the support of the spring, thus avoiding the deviation of the multi-layer board during the positioning process. During the hot pressing process, the hydraulic lifting device drives the lifting plate to descend, and then the pressing plate at the bottom contacts the solid wood board. As the pressure continuously increases, the pressing of the solid wood board is realized. If the area of the board is smaller than that of the pressing plate, the baffle assembly is located below the pressing plate. After contacting the movable baffle, it makes the movable baffle contract towards the inside of the fixed baffle, thus avoiding the conflict between the two. At the same time, the movable baffle still supports the solid wood board on the side, thus avoiding the deviation of the board during the pressing process. This structure is convenient to operate and has high flexibility. It can not only be flexibly adjusted according to the specifications of different square boards, but also cooperate with the upper pressing plate to move, effectively improving the practicability.

[0017] 2. The utility model is provided with negative pressure suction cups at the four corners of the bottom of the pressing plate. The negative pressure suction cups are installed in the grooves of the pressing plate through telescopic tubes. As the pressing plate descends, the negative pressure suction cups first contact the board. When the pressing plate contacts the solid wood board, the negative pressure suction cups contract into the grooves under the reaction force. At the same time, they are closely attached to the solid wood board under the action of the support spring outside the telescopic tube. After the hot pressing is completed, the vacuum pump is turned on, and the internal air is quickly evacuated through the air pipe to generate negative pressure inside the negative pressure suction cups, realizing the tight fixation of the bottom end of the negative pressure suction cups to the solid wood board. When the hydraulic lifting device drives the lifting plate to rise, the solid wood board can rise with the pressing plate, thus moving out of the blocking range of the baffle, and the staff can quickly take it out, providing convenience for high-efficiency production.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please refer to Figures 1-4 , an embodiment provided by the present invention: a hot pressing device for solid wood boards, including a base 1, an outer shell 2 is welded and fixed to the outer edge of the upper end of the base 1, a hydraulic lifting device 3 is installed at the middle position of the upper end face of the outer shell 2, and the movable end of the hydraulic lifting device 3 extends into the interior of the outer shell 2. One end of the hydraulic lifting device 3 located inside the outer shell 2 is fixedly installed with a lifting plate 4, and a pressing plate 5 is fixedly installed at the bottom of the lifting plate 4; further includes:

[0025] A pressing table 6, which is arranged at the middle position of the upper end face of the base 1. Screw rods 10 are installed around the inside of the pressing table 6, and the screw rods 10 are rotatably connected to the pressing table 6. A sliding block 11 is installed on the outside of the screw rods 10, and the sliding block 11 is threadedly connected to the screw rods 10;

[0026] A fixed baffle 16, which is arranged around the upper end face of the pressing table 6, and the bottom of the fixed baffle 16 is fixed to the sliding block 11. A movable baffle 17 is installed inside the fixed baffle 16, and the fixed baffle 16 is slidably connected to the movable baffle 17.

[0027] During use, by turning on the servo motor 7, its output shaft drives the driving bevel gear 8 to rotate. Under the engagement with the driven bevel gear 9, the screw 10 is driven to rotate. Thread friction occurs between the screw 10 and the sliding block 11, converting the rotational motion into linear motion. Thus, the fixed baffle 16 is driven by the sliding block 11 to move in the opposite direction of the solid wood board. With the cooperation of the four fixed baffles 16, pre-positioning of the board is achieved. The movable baffle 17 can be higher than the upper end face of the board under the support of the spring 20, thus avoiding the offset of the multi-layer board during the positioning process. During the hot pressing process, the hydraulic lifting device 3 drives the lifting plate 4 to descend, and then the pressing plate 5 at the bottom contacts the solid wood board. With the continuous increase of pressure, the pressing of the solid wood board is realized. If the area of the board is smaller than that of the pressing plate 5, the baffle assembly is located below the pressing plate 5. After contacting the movable baffle 17, it causes the movable baffle 17 to contract towards the inside of the fixed baffle 16, thus avoiding the conflict between the two. At the same time, the movable baffle 17 still supports the solid wood board on the side, thus avoiding the offset of the board during the pressing process.

[0028] Please refer to Figure 1 , a servo motor 7 is fixedly installed inside the base 1. The output shaft of the servo motor 7 is installed with a driving bevel gear 8. The driving bevel gear 8 is meshed and installed with a driven bevel gear 9 around it. And the shaft at one end of the driven bevel gear 9 is fixed to the screw 10 at the corresponding position. This structure is convenient to operate and has high flexibility. It can not only be flexibly adjusted according to the specifications of different square boards, but also cooperate with the upper pressing plate to move, effectively improving the practicability.

[0029] Please refer to Figure 2 and Figure 3 , limit grooves 19 are provided on both sides of the inner cavity of the fixed baffle 16. Limit blocks 18 are provided on both sides of the movable baffle 17. And the limit blocks 18 are slidably limited by the limit grooves 19. A spring 20 is fixedly installed between the limit grooves 19 and the limit blocks 18 to ensure that the movable baffle 17 always contacts the side of the board.

[0030] Please refer to Figure 2 and Figure 3 , the inner walls of the fixed baffle 16 and the movable baffle 17 are both on the same vertical plane to avoid affecting the anti-offset effect on the board due to distance differences.

[0031] Please refer to Figure 1 , negative pressure suction cups 13 are installed in the grooves at the four corners of the bottom of the pressing plate 5. The negative pressure suction cups 13 are connected to the grooves at the bottom of the pressing plate 5 through telescopic tubes equipped with support springs. A vacuum pump 15 is fixedly installed on one side of the upper end face of the housing 2. The negative pressure end of the vacuum pump 15 is installed with an air pipe 14. And the other end of the air pipe 14 is hermetically connected to the telescopic tube above the negative pressure suction cup 13, which can quickly take out the pressed board and provide convenience for high-efficiency production.

[0032] Please refer to Figure 1 , an electric heating wire 12 is installed at the lower end inside the pressing plate 5, and the electric heating wire 12 heats the pressing plate 5, thereby realizing the hot pressing of the board material.

[0033] Furthermore, the height of the fixed baffle 16 is lower than the upper end surface of the solid wood board.

[0034] Working principle: During use, as the pressing plate 5 descends, the negative pressure suction cup 13 first contacts the board material. When the pressing plate 5 contacts the solid wood board, the negative pressure suction cup 13 contracts into the groove under the reaction force, and at the same time, it clings to the solid wood board under the action of the outer support spring of the telescopic tube. After the hot pressing is completed, the vacuum pump 15 is turned on, and the internal air is quickly evacuated through the air pipe 14 to generate negative pressure inside the negative pressure suction cup 13, realizing the tight fixation of its bottom end to the solid wood board. When the hydraulic lifting device 3 drives the lifting plate 4 to rise, the solid wood board can rise with the pressing plate 5, thus moving out of the blocking range of the baffle, and the staff can quickly take it out.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
