[0003] Current hot pressing equipment requires manual placement of the boards during use. After hot pressing, the boards are removed and new boards are placed for the next hot pressing cycle. This results in low continuous operating efficiency, slow board processing speed, and a significant amount of manual labor, reducing the overall ease of use of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a hot pressing device for processing reconstituted bamboo boards, so as to solve the problems mentioned in the background art. The current hot pressing device requires manual placement of the boards during use, and after hot pressing, the boards are removed and then new boards are placed for hot pressing. The continuous working efficiency of the device is low, the processing speed of the boards is slow, and it requires a lot of manual labor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot pressing device for processing reconstituted bamboo boards, comprising a base, a mounting frame, a hydraulic rod, and a lower pressing seat. The mounting frame is fixed above the base, and a hydraulic rod is installed below the mounting frame. The lower pressing seat is connected below the hydraulic rod. A movable plate is provided below the lower pressing seat, and a placement groove is evenly opened inside the movable plate for placing boards. The lower pressing seat moves down to press the boards in the placement groove. A rotary drive mechanism is connected to the middle of the movable plate to control the rotation of the movable plate. A storage cover is provided above and behind the movable plate, and the storage cover is connected to the mounting frame. The lower opening of the storage cover corresponds to the placement groove. A feeding mechanism is provided inside the base to transport the hot-pressed boards. A blocking mechanism is provided on the outside of the lower pressing seat to block the upper side of the placement groove.

[0006] To further optimize this technical solution, a first heating module is provided inside the lower pressure seat, and a second heating module is provided below the lower pressure seat. The second heating module is located inside the base, and a pressure sensor is provided below the second heating module.

[0007] To further optimize this technical solution, the rotary drive mechanism includes a drive shaft and a motor. The drive shaft is fixed in the middle of the movable disk, and a motor that provides rotational power to the drive shaft is connected below the drive shaft.

[0008] To further optimize this technical solution, an adjustment head is provided below the storage cover, and the adjustment head and the storage cover form an up-and-down sliding structure. A connecting plate is fixed to the outside of the adjustment head, and a telescopic device is connected above the connecting plate.

[0009] To further optimize this technical solution, the feeding mechanism includes a feeding trough and a conveying mechanism. The feeding trough is located above the base to collect the hot-pressed plates, and the conveying mechanism is installed inside the feeding trough.

[0010] To further optimize this technical solution, the shielding mechanism includes a protective cover, a connecting frame, and a return spring. The protective cover is sleeved on the outside of the lower pressure seat, and the connecting frame is connected above the protective cover. A guide post runs through the inside of the connecting frame, and the lower part of the guide post is connected to the lower pressure seat. A return spring is provided on the outside of the guide post to provide a downward pushing force for the connecting frame.

[0011] To further optimize this technical solution, an auxiliary rod is connected above the lower pressure seat, and the lower end of the auxiliary rod is designed with an inclined structure. A positioning groove is provided below the auxiliary rod. The positioning groove is opened on the upper surface of the base, and the positioning groove and the auxiliary rod form a concave-convex fit structure. A connecting groove is opened on the surface of the movable plate, and the connecting groove and the auxiliary rod form a concave-convex fit structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By rotating the movable plate and cooperating with the placement slot, the plates to be processed can be transferred to the bottom of the pressure seat in sequence. Then, the pressure seat moves down to perform hot pressing. After hot pressing, the movable plate continues to rotate to automatically discharge the plates, so that the subsequent placement slot can continue to receive the plates to be processed, thus realizing continuous hot pressing, reducing manual labor, and improving processing efficiency.

[0014] (2) The boards to be processed are stored in the storage cover. As the movable plate rotates, the boards stacked in the storage cover can automatically fall into the placement slot, realizing automatic feeding of the boards. The height of the adjustment head under the storage cover can be adjusted to adapt to the feeding of boards of different thicknesses, so that the movable plate can smoothly bring them out from under the storage cover.

[0015] (3) The movable plate can be positioned by connecting the auxiliary rod and the connecting groove, so that the upper part of the subsequent protective cover and the placement groove can be accurately aligned, and the subsequent hot pressing operation can be carried out stably. The auxiliary rod can move automatically with the vertical movement of the lower pressure seat, automatically positioning the movable plate before hot pressing and automatically releasing the positioning after hot pressing is completed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Example 1: This utility model provides the following technical solution: Figure 1-3 As shown, a hot pressing device for processing reconstituted bamboo boards includes a base 1, a mounting frame 2, a hydraulic rod 3, and a lower pressing seat 4. The mounting frame 2 is fixed above the base 1, and the hydraulic rod 3 is installed below the mounting frame 2. The lower pressing seat 4 is connected below the hydraulic rod 3, and a movable plate 8 is provided below the lower pressing seat 4. The movable plate 8 has evenly spaced placement grooves 9 inside, which are used to place boards. The lower pressing seat 4 moves down to press the boards in the placement grooves 9. A rotary drive mechanism is connected to the middle of the movable plate 8 to control the rotation of the movable plate 8. The rear upper part of the movable plate 8... The base 1 is equipped with a storage cover 12, which is connected to the mounting frame 2. The lower opening of the storage cover 12 corresponds to the placement slot 9. The base 1 is equipped with a feeding mechanism to transport the hot-pressed plates. The lower pressure seat 4 is equipped with a shielding mechanism on its outer side, which shields the upper side of the placement slot 9. The lower pressure seat 4 is equipped with a first heating module 5, and a second heating module 6 is located below the lower pressure seat 4. The second heating module 6 is located inside the base 1, and a pressure sensor 7 is located below the second heating module 6.

[0026] In use, the boards to be processed can be stacked inside the storage cover 12. The boards fall through the storage cover 12 into the placement slot 9 on the movable plate 8. When the movable plate 8 rotates, it will drive the placement slot 9 to move, moving the boards. After the boards are moved to the bottom of the pressure seat 4, the rotation of the movable plate 8 stops, and the pressure seat 4 is moved downward by the hydraulic rod 3 to perform hot pressing on the boards. The boards are heated by the first heating module 5 and the second heating module 6, and the pressure is detected by the pressure sensor 7. After hot pressing is completed, the movable plate 8 continues to rotate, and the hot-pressed boards are discharged through the feeding mechanism. At the same time, the next set of boards moves to the bottom of the pressure seat 4 to continue hot pressing.

[0027] Example 2: Based on Example 1, as follows Figure 4-6 As shown, the rotary drive mechanism further discloses a drive shaft 10 and a motor 11. The drive shaft 10 is fixed in the middle of the movable disk 8, and the motor 11, which provides rotational power to the drive shaft 10, is connected below the drive shaft 10. An adjustment head 13 is provided below the storage cover 12, and the adjustment head 13 and the storage cover 12 form an up-and-down sliding structure. A connecting plate 14 is fixed to the outside of the adjustment head 13, and a telescopic device 15 is connected above the connecting plate 14. The feeding mechanism includes a feeding trough 16 and a conveying mechanism 17. The feeding trough 16 is opened above the base 1 to collect the hot-pressed plates, and the conveying mechanism 17 is installed inside the feeding trough 16.

[0028] The drive shaft 10 is driven by the motor 11 to rotate, and the drive shaft 10 drives the movable disc 8 to rotate. When the hot-pressed plate moves to the unloading trough 16, it will fall onto the surface of the conveying mechanism 17 and be sent out by the conveying mechanism 17. The adjustment head 13 can be moved to adapt to different plate thicknesses. When the plate thickness increases, the adjustment head 13 can be moved upward by the telescopic device 15 to increase the height of the storage cover 12 so that the plate can pass smoothly under the adjustment head 13. When the plate thickness decreases, the adjustment head 13 can be moved downward to prevent the plate from falling from under the storage cover 12.

[0029] Example 3: Based on Example 2, such as Figure 7As shown, the shielding mechanism further discloses a protective cover 18, a connecting frame 19, and a return spring 20. The protective cover 18 is sleeved on the outside of the lower pressure seat 4, and the connecting frame 19 is connected above the protective cover 18. A guide post 1901 passes through the inside of the connecting frame 19. The lower part of the guide post 1901 is connected to the lower pressure seat 4, and a return spring 20 is provided on the outside of the guide post 1901 to provide a downward pushing force for the connecting frame 19. An auxiliary rod 21 is connected above the lower pressure seat 4, and the lower end of the auxiliary rod 21 is designed with an inclined structure. A positioning groove 23 is provided below the auxiliary rod 21. The positioning groove 23 is opened on the upper surface of the base 1, and the positioning groove 23 and the auxiliary rod 21 form a concave-convex fit structure. A connecting groove 22 is opened on the surface of the movable disk 8, and the connecting groove 22 and the auxiliary rod 21 form a concave-convex fit structure.

[0030] When the pressure seat 4 moves downward, the auxiliary rod 21 moves downward synchronously. The auxiliary rod 21 first inserts its tip into the connecting groove 22 to position the movable plate 8. Then, the protective cover 18 and the movable plate 8 fit together to block the top of the placement groove 9. Then the pressure seat 4 continues to move, the return spring 20 is compressed, and the protective cover 18 maintains its own stable position. After the heat pressing is completed, the pressure seat 4 rises and resets, and the connection between the auxiliary rod 21 and the connecting groove 22 is released.
