Traditional positioning structures mostly use fixed slots or baffles, which cannot be flexibly adjusted according to different specifications of plywood. During the pressing process, due to the lack of effective constraints, the plywood is very easy to shift in position due to the pressure of the pressing plate, the vibration of the conveyor belt, and other factors, which affects the pressing quality. Therefore, the above problems need to be solved. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses a pressing device based on plywood production, comprising a machine body 1 and a base plate 2 welded to the bottom of the machine body 1. Four support frames 4 are fixedly connected to the base plate 2. The support frames 4 ensure that the conveyor belt 3 does not sag or deviate during operation, thus ensuring smooth plywood conveying. The conveyor belt 3 is installed between the four support frames 4, which ensures that the plywood can be smoothly and quickly transported before and after pressing, reducing manual handling and improving production efficiency. A second motor 7 for driving the conveyor belt 3 is installed on one side of each support frame 4. The second motor 7 ensures that the conveyor belt 3 runs at a stable speed, so that the plywood can be evenly and continuously transported to the pressing area. A pressing component is provided inside the machine body 1, and a guide component is installed on the pressing component. Support plates are fixedly connected to both sides of the machine body 1, and a bearing plate is fixed between two support plates by bolts. Multiple limiters are symmetrically provided on both sides of the bearing plate, which facilitates the implementation of plywood pressing.

[0020] In this invention, the pressing component includes a bidirectional lead screw 8 located at both ends of the inner wall of the machine body 1. Two movable blocks are threaded onto the bidirectional lead screw 8, and an electric pusher cylinder 12 is installed at the bottom of each movable block. An arc-shaped protective pad is fitted onto the output end of the electric pusher cylinder 12. Support shafts are fixed to both sides of each movable block. The pressing component facilitates the provision of stable and adjustable pressure to meet the pressing requirements of different types of plywood. A fixed block is welded to the outer wall of one end of the machine body 1, and a first motor 5 is installed on the fixed block. The output end of the first motor 5 is coaxially connected to the bidirectional lead screw 8. The bidirectional lead screw 8 allows for flexible adjustment of the pressing area and pressing force distribution according to the size of the plywood and the pressing requirements. The guiding component includes a telescopic column 9 installed on the inner wall of the top of the machine body 1. A connecting block is welded to the output end of the telescopic column 9, and two pairs of movable rods are rotatably connected to both sides of the connecting block. One end of each pair of movable rods rotates... Connected to the support shaft, the guide component facilitates smoother and more precise movement of the pressing components. Multiple limiting grooves are provided on the bearing plate. Each limiting device includes a limiting block 13 that slides within the limiting groove. A threaded post is threaded into the limiting block 13. A third motor is installed on the side wall of the support frame 4, with its output coaxially connected to the threaded post. The limiting device effectively restricts the movement of the plywood, ensuring its stability during pressing and preventing a decrease in pressing quality due to positional deviations. Four springs 10 are fixedly attached to the four corners of the bearing plate. Each spring 10 has a guide post 6 fixedly attached to it. A pressing plate 11 slides on each of the four guide posts 6. The top of each spring 10 abuts against the bottom of the pressing plate 11, and the output of the electric push cylinder 12 abuts against the top surface of the pressing plate 11. The four springs 10 facilitate rapid reset of the pressing plate 11 after pressing, improving pressing efficiency.

[0021] Working Principle: In the use of this utility model, the conveyor belt 3 is first installed between four support frames 4. Under the action of power, it runs at a stable speed and direction, conveying the plywood raw material from one end of the device to the pressing area. By adjusting the speed of the second motor 7, the running speed of the conveyor belt 3 can be flexibly controlled to match the rhythm of the pressing process, realizing continuous and automatic transmission of plywood. Next, the first motor 5 is installed on a fixed block on the outer wall of one end of the machine body 1. When it is necessary to adjust the position of the pressing components to accommodate plywood of different sizes, the first motor 5 is started. The output end of the first motor 5 is coaxially connected to the bidirectional lead screw 8, driving the bidirectional lead screw 8 to rotate. The thread structure of the bidirectional lead screw 8... The two moving blocks move in opposite directions on the lead screw, thereby adjusting the position of the pressing components such as the electric push cylinder 12 and the pressing plate 11 installed at the bottom of the moving blocks. Simultaneously, the telescopic column 9 on the inner wall of the top of the machine body 1 moves the connecting block up and down through its telescopic movement. The movable rods rotatably connected to both sides of the connecting block are connected to the support shafts on both sides of the moving block, converting the linear motion of the telescopic column 9 into the translational motion of the moving block. This provides guidance and auxiliary power for the movement of the moving block, ensuring that the pressing components can move accurately and smoothly to the appropriate position, achieving personalized pressing preparation for plywood of different specifications. Then, after the plywood is conveyed to the pressing area, the electric push cylinder 12 begins to work. Installed at the bottom of the movable block, its output end is fitted with an arc-shaped protective pad and abuts against the top surface of the pressing plate 11. The electric push cylinder 12 transmits pressure to the pressing plate 11 through its telescopic movement. During the downward movement of the pressing plate 11, the guide column 6 provides guidance to ensure that the pressing plate 11 moves vertically up and down, preventing deviation or tilting. The springs 10 at the four corners of the bearing plate are sleeved on the guide column 6, with their tops abutting against the bottom of the pressing plate 11. They play a buffering and shock-absorbing role during the pressing process, absorbing the impact force generated during pressing and preventing damage to the plywood or equipment parts due to excessive pressure. At the same time, the rebound force of the springs 10 can assist the pressing plate 11 to automatically reset after pressing is completed, waiting for the next pressing. In the pressing process, the pressing plate 11 applies uniform pressure to the plywood, ensuring that each layer of the plywood is tightly bonded together, thus completing the pressing process. Finally, before the plywood enters the pressing area, the third motor drives the threaded column to rotate. The threaded column is threadedly connected to the limiting block 13, causing the limiting block 13 to move within the limiting groove of the bearing plate. According to the size of the plywood and the pressing requirements, the position of the limiting block 13 is adjusted to accurately position and limit the plywood. The limiting block 13 restricts the movement of the plywood during the pressing process, ensuring that it maintains an accurate position within the pressing area and avoiding a decrease in pressing quality due to positional deviation. This provides a guarantee for high-quality pressing operations, and the use of the pressing device based on plywood production is thus completed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
