[0022] The hot press 100 unloading mechanism 200 provided in this application achieves one-time automated unloading of multiple wooden boards by precisely matching the gap between the adjustable push rod 34 and the multi-layer laminate 10, combined with the synchronous drive design of the moving frame 31, significantly improving work efficiency. The adjustable spacing of the push rod 34 and the guiding structure of the guide wheel group 32 ensure stable and reliable insertion action, avoiding the safety risks of manual operation; the overall modular design takes into account the compatibility of different specifications of boards, and the synchronous demolding accuracy is high, solving the problems of low efficiency and easy damage to boards in traditional manual unloading, greatly reducing production costs and safety hazards.

[0023] For details, please continue reading Figure 1 and Figure 2 The hot press 100 includes a laminating plate 10, a hydraulic cylinder 11, and a base 13. Two parallel baffles 14 are provided at both ends of the upper surface of the base 13, forming a compression space between the two baffles 14. The hydraulic cylinder 11 is fixed to the outside of one baffle 14, and its output shaft extends through the baffle 14 into the compression space. A square compression plate 12 is provided at the end of the output shaft of the hydraulic cylinder 11. Multiple vertically oriented laminating plates 10 are arranged between the compression plate 12 and the other baffle 14. A sliding groove is provided on the upper surface of the base 13 along the direction of movement of the laminating plates 10. A track assembly is provided in the sliding groove and connected to the bottom of the laminating plates 10 to facilitate movement of the laminating plates 10. A steam channel is provided inside the laminating plate 10 and communicates with a slide 42. An air inlet for an external steam source is provided on the slide 42. Multiple steam exhaust holes are evenly distributed on the working surface of the laminating plate 10 to facilitate the hot pressing and shaping of wood.

[0024] Further, please refer to Figure 1 and Figure 2 To enhance the stability of the laminate 10, a limiting component 40 is provided at the upper end of the laminate 10 near a diagonal position. The limiting component 40 includes a horizontally extending slide rod and a slide seat 42. The two ends of the slide rod are fixed to the fixing frame 20, and the slide seat 42 is located on the side of the laminate 10 and is provided with a sliding through hole that matches the slide rod. Alternatively, one corner of the upper end of the laminate 10 protrudes outward to form a lug (i.e., the slide seat 42), and the lug is provided with a through hole that matches the slide rod for sliding.

[0025] The fixing frame 20 is composed of multiple fixing rods 201 forming a grid-like structure. The bottom ends of the fixing rods 201 are fixed to the ground, and the grid-like structure is located on the outer side of the baffle 14, and is fixed to each other by screws or welding. Two grid-like structures are fixedly connected by four fixing rods 201. The upper end of the fixing frame 20 is provided with two parallel and spaced fixing rods 201, which extend axially in the direction of material ejection. Both fixing rods 201 are provided with guide rails 202 for the movement of the moving assembly 30.

[0026] Please see Figure 2and Figure 3 The movable component 30 is positioned above two parallel fixed rods 201. The movable component 30 includes a movable frame 31, guide wheel sets 32, connecting rods 33, push rods 34, and drive motor 35. The movable frame 31 has a rectangular frame structure. The two sets of guide wheel sets 32 are respectively located below the short sides at both ends of the movable frame 31, and each set of guide wheel sets 32 is correspondingly mounted on a fixed rod 201.

[0027] The guide wheel assembly 32 includes two main guide wheels 321 and one auxiliary guide wheel 323. The two main guide wheels 321 are fixed to the lower part of the short side of the movable frame 31 by flange seats, and the main guide wheels 321 abut against the guide rail 202. The outer side of the fixed rod 201 is provided with a slot 203. The bottom of the same end of the movable frame 31 extends downward to form an L-shaped extension rod 311. The end of the extension rod 311 is provided with an auxiliary guide wheel 323, and the rim of the auxiliary guide wheel 323 is embedded in the slot 203. The wheel surface of the main guide wheel 321 is concave to form a concave surface corresponding to the guide rail 202, and the concave surface covers the guide rail 202. The two main guide wheels 321 and the auxiliary guide wheel 323 form a stable triangular structure, which firmly clamps the movable frame 31 onto the fixed rod 201.

[0028] Please continue reading. Figure 2 The inner sides of the short sides at both ends of the movable frame 31 extend downwards to form support rods 312. The two ends of the connecting rod 33 are fixed to the free ends of the support rods 312. The support rods 312 and push rod 34 are located in the middle between the two main guide wheels 321, or in other words, in the middle of the short side. The central axes of the connecting rod 33, push rod 34, extension rod 311, and support rod 312 are collinear and symmetrical about the longitudinal (short side) centerline of the movable frame 31. In other words, the central axes of these four components (connecting rod 33, push rod 34, extension rod 311, and support rod 312) are all located in the middle of the short side of the movable frame 31, and the two main guide wheels 321 on the short side are symmetrical about the center. This symmetrical arrangement ensures that the movable frame 31 is subjected to uniform force, facilitating the ejection of the wooden board and improving the service life of the equipment.

[0029] One end of the push rod 34 is provided with a collar 341. Multiple push rods 34 are fitted onto the connecting rod 33 through corresponding collars 341 and can move relative to each other. The collars 341 are fixed to the connecting rod 33 by screws. The push rods 34 extend in a vertical direction, and the bottom end of the push rod 34 is provided with a crossbar 342 that increases the cross-sectional area. The crossbar 342 helps to smoothly push the wood board out of the gap in the laminate 10. When it is necessary to adjust the distance between the push rods 34 to correspond with the gap in the laminate 10, the screws can be loosened, and after adjustment, they can be tightened.

[0030] The drive motor 35 is mounted above one short side of the movable frame 31, and its output shaft is connected to one of the main drive wheels 321 via a belt to drive the entire movable frame 31 to move back and forth along the guide rail 202.

[0031] The working process of the unloading mechanism 200 of the hot press 100 is as follows:

[0032] 1. Hot pressing completed, ready for unloading.

[0033] After the hot press 100 completes the hot pressing of the wood, the hydraulic cylinder 11 retracts, causing the pressing plate 12 to detach from the laminate 10, forming a fixed gap between adjacent laminates 10, and the internal wood boards are in a state of waiting to be unloaded. The laminate 10 is kept in a stable position by the slide rail assembly, the steam passage is closed, and the hot press 100 enters the unloading stage.

[0034] 2. Drive motor 35 starts, and the moving frame 31 moves horizontally.

[0035] The operator starts the drive motor 35, which drives the main guide wheel 321 to rotate via belt drive. Guided by the guide wheel group 32 (a triangular stable structure formed by the main guide wheel 321 and the auxiliary guide wheel 323), the moving frame 31 slides horizontally towards the laminate 10 along the guide rail 202 on the fixed rod 201.

[0036] 3. Push rod 34 is simultaneously inserted into the gap of laminate 10.

[0037] During the movement of the moving frame 31, multiple push rods 34 are precisely aligned with the gaps in the laminate 10 according to a preset spacing. The push rods 34 are fixed to the connecting rods 33 by collars 341, and their vertically extending crossbars 342 are inserted into the corresponding gaps in the laminate 10 simultaneously with the moving frame 31, ensuring that all push rods 34 contact the side of the wooden board to be unloaded at the same time.

[0038] 4. Push the wooden boards to demold and unload.

[0039] As the moving frame 31 continues to move forward, the crossbar 342 at the end of the push rod 34 applies a horizontal pushing force, smoothly pushing each layer of wood planks out of the gaps in the laminate 10. The enlarged cross-section design of the crossbar 342 enhances the uniformity of the pushing force, prevents the wood planks from shifting or getting stuck, and ensures that the unloading of multiple layers of wood is completed in one go.

[0040] 5. The movable frame 31 returns to its original position, and the push rod 34 retracts from the clearance.

[0041] After unloading is completed, the drive motor 35 reverses and the moving frame 31 returns to its initial position along the guide rail 202.

[0042] Push rod 34, along with moving frame 31, exits the gap between laminar flow plates 10, completely disengaging from the working area of ​​hot press 100. During the reset process, guide wheel assembly 32 maintains a stable movement trajectory. (Cycle preparation and adaptive adjustment)

[0043] To accommodate different sheet metal sizes, loosen the collar 341 screws, adjust the spacing of the push rods 34 until they match the new gap of the laminate 10, and then tighten them.
