[0001] This utility model relates to the field of hot pressing molding machine technology, and in particular to a flame-retardant plywood hot pressing molding machine. Background Technology

[0002] The plywood hot press is one of the main pieces of equipment in the plywood production process. It is used to hot press and bond glued plywood blanks after they have been coated and assembled. In the plywood production process, hot press forming machines are usually used to assist in the processing of plywood.

[0003] For example, the Chinese utility model patent with publication number CN221561688U can position the plywood, making placement and fixing more convenient and preventing misalignment during the pressing process, thus improving the yield of the device. By sliding the fixing plate inside the mounting vertical plate and inserting the pin inside the fixing plate for fixation, the device is designed to be openable, making it easier to remove the plywood. However, since multiple plywoods are hot-pressed simultaneously, and the positioning of each plywood requires manual operation, the positioning process is cumbersome and time-consuming. Therefore, we propose a flame-retardant plywood hot-pressing machine. Utility Model Content

[0018] Please see Figure 1-5 This utility model provides a technical solution: a flame-retardant plywood hot pressing molding machine, including a base plate 1, two vertical plates 2 fixedly connected to the upper surface of the base plate 1, a top plate 3 fixedly connected between the two vertical plates 2, a hydraulic push rod 4 and a heating element 5 fixedly connected to the base plate 1, a push plate 6 fixedly connected to the upper end of the hydraulic push rod 4, a bearing plate 7 fixedly connected to the upper surface of the push plate 6, two sliding grooves 8 opened on the front surface of the bearing plate 7, the rear side of the sliding grooves 8 extending out of the rear surface of the bearing plate 7, a first limiting rod 9 fixedly connected to the inner walls of the left and right sides of the sliding grooves 8, a U-shaped positioning plate 10 provided on the base plate 1, a groove 11 opened on the bearing plate 7, an automatic positioning component provided on the groove 11, the automatic positioning component is automatically triggered when the hydraulic push rod 4 drives the bearing plate 7 to rise, and the U-shaped positioning plate 10 is used to complete the positioning of the board. The entire positioning process does not require manual operation, greatly improving the convenience.

[0019] Furthermore, the automatic positioning component includes a first spring 12, which is fixedly connected to the bottom wall of the groove 11. A pressure plate 13 is fixedly connected to the upper end of the first spring 12. Limiting grooves 14 are formed on the inner walls of both the front and rear sides of the groove 11. An L-shaped limiting plate 15 is fixedly connected to the lower surface of the pressure plate 13. The horizontal plate of the L-shaped limiting plate 15 extends into the interior of the limiting groove 14. The horizontal plate of the L-shaped limiting plate 15 is slidably connected to the limiting groove 14. A through groove 16 extending into the sliding groove 8 is formed on the inner wall of the groove 11. A horizontal plate 17 is fixedly connected between the two vertical plates of the U-shaped positioning plate 10. The horizontal plate 17 is slidably sleeved on the outer surface of the first limiting rod 9. A rotating groove 18 is formed on the inner wall of the groove 11. A rotating shaft 19 is rotatably connected to the inner wall of the rotating groove 18. The lower surface of the pressure plate 13... A cable 20 is fixedly connected to the surface of the bearing plate 7. The cable 20 is fixedly connected to the horizontal plate 17 via a pivot 19. A second spring 21 is fixedly connected between the horizontal plate 17 and the inner wall of the sliding groove 8. A fixed positioning plate 22 is fixedly connected to the upper surface of the bearing plate 7. A clearance groove 25 adapted to the fixed positioning plate 22 is opened on the lower surface of the U-shaped positioning plate 10. Limit sleeves 23 are fixedly connected to both the front and rear surfaces of the bearing plate 7. A second limiting rod 24 is fixedly connected between the bottom plate 1 and the top plate 3. The limiting sleeve 23 is slidably sleeved on the outer surface of the second limiting rod 24. The fixed positioning plate 22 can provide a certain initial positioning point for the plate. During hot pressing, since there is no gap in the area where the plate is placed on the bearing plate 7, no indentation will appear on the plate after hot pressing, thus improving the quality of the plate.

[0020] The hydraulic push rod 4 and the heating element 5 are existing structures, which can be referred to in patent publication number CN221561688U. The second spring 21 is in a stretched state when the plate is not clamped. The elastic force of the second spring 21 is less than that of the first spring 12. Since it is not a major structure, it will not be described in detail.

[0021] Working principle: When hot pressing plywood, the board is placed on the upper surface of the bearing plate 7, so that the rear surface of the board is in close contact with the fixed positioning plate 22. At this time, the bearing plate 7 can be driven to rise by the hydraulic push rod 4 and the push plate 6. When the bearing plate 7 rises, the pressure plate 13 moves into the groove 11 by the restriction of the top plate 3. When the pressure plate 13 moves, the movement trajectory is restricted by the L-shaped limiting plate 15. When the pressure plate 13 moves, the first spring 12 is compressed simultaneously. Since the second spring 21 is in a stretched state, the cable 20 is gradually relaxed when the pressure plate 13 falls. Under the action of the second spring 21, the U-shaped positioning plate 10 is pulled towards the board, thereby completing the positioning of the board. When the U-shaped positioning plate 10 moves, the movement trajectory is restricted by the first limiting rod 9. When the cable 20 moves, the friction of its movement is reduced by the rotating shaft 19.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
