[0002] Since wood processing machinery has functions such as shaping, cutting, splicing, polishing, and sanding of wood, it is widely used in various processing occasions of wooden boards, wooden poles, wooden columns, etc. After the processing of wooden poles, wooden strips or wooden columns is completed, operators usually organize and stack the processed wood.

[0003] During the wood processing process, after the wood is processed into wooden boards, it is sorted and stacked by a conveyor belt in cooperation with a stacking machine. However, during the conveying process, the position of the wood on the conveyor belt is not fixed, which will affect the subsequent stacking. Therefore, a pusher device is needed to push the wood to the central position of the conveyor belt. When performing centering pushing, the method of using a fixed guiding plate is usually adopted, and the wood is positioned through the guiding plate to ensure that it is in the center of the conveyor belt. However, due to the inconsistency of the wood sizes, it is easy to get stuck between the guiding plates during the conveying process, which will interfere with the subsequent stacking process.

[0009] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0010] Refer to Figures 1 to 3The present invention provides an embodiment: a wood stacking device for wood product production, including a conveyor belt 1, which realizes the transmission of wooden boards by rolling on the surface rollers. When the wooden boards are placed on it, they are driven to move along its surface by relying on the running power of the conveyor belt 1. A stacking frame 2 is fixedly connected to one side of the conveyor belt 1, and the stacking frame 2 is fixedly connected to the conveyor belt 1 and the conveyor belt 2 3. At the same time, during the stacking process, the spatial range of the wood stacking is limited to guide the wood to be stacked in a predetermined manner. The right side of the stacking frame 2 is fixedly connected to the conveyor belt 2 3, and the conveyor belt 2 3 realizes the subsequent transportation of the wood after stacking, and cooperates with the conveyor belt 1 and the stacking part to form a complete wood processing and transportation assembly line, so that the wood can be smoothly transferred to the next processing link, thereby improving production efficiency.

[0011] The lifting parts and the fixed plate 8 are fixedly connected to the conveyor belt 1, and the front and rear sides of the fixed plate 8 are rotatably connected with a turntable 9. The fixed plate 8 is fixedly connected to the middle part of the bottom end of the conveyor belt 1 by bolts, providing a rotation support basis for the turntable 9. During the transportation of wood, the turntable 9 rotates with the middle position of the front and rear sides of the fixed plate 8 as the center to realize the centering operation of the wood.

[0012] The lifting member includes a hydraulic cylinder 4, the bottom end of which is fixedly connected to the inner bottom end of the stacking frame 2, and the bottom end is fixed to the inner bottom end of the stacking frame 2. After the hydraulic cylinder 4 is started, the stacking roller pad 5 at the top is pushed to perform telescopic movement by hydraulic action. During the stacking process, the rise and fall of the stacking roller pad 5 is controlled to adjust the height position of the wooden board, so as to realize the layer-by-layer stacking and final stacking and transportation of the wooden board. The top of the hydraulic cylinder 4 is provided with a stacking roller pad 5. On the one hand, the stacking roller pad 5 provides a stacking bearing platform for the wooden board, and realizes the stacking operation of the wooden board by lifting; on the other hand, its roller design facilitates the smooth transfer of the stacked wooden boards to the conveyor belt 2 3, reduces manual handling, and improves the stacking and transportation efficiency.

[0013] The stacking frame 2 is fixedly connected to the front and rear sides thereof with clamping rollers 6, and the stacking frame 2 is rotatably connected to the front and rear sides thereof with support rods 7, the outside of the support rods 7 is engaged with the outside of the clamping rollers 6, and the engagement with the support rods 7 limits the rotation angle and position of the support rods 7, ensuring that during the stacking process, the support rods 7 can stably support the wood and prevent it from shaking at will.

[0014] refer to Figure 3 and Figure 4, the bottom end of the fixed plate 8 is fixedly connected with a mounting bracket 10. During the process of adjusting the inclination angle of the adjusting rotating frame 9, the mounting bracket 10 serves as a carrier for support and connection, ensuring the coordinated operation of each adjusting component. A sliding sleeve 11 is slidably connected to the middle of the mounting bracket 10, and the sliding sleeve 11 is used to position the central shaft 12. The top end of the sliding sleeve 11 is fixedly connected with a central shaft 12, and a torsion spring 13 is sleeved outside the central shaft 12. The central shaft 12 limits the position of the torsion spring 13. The left and right ends of the central shaft 12 are both rotatably connected with a curved rod 14. When the rotating frame 9 is pressed and opened, driving the curved rod 14 to rotate and pulling the square plate 15 to rotate, the torsion spring 13 is pulled and unfolded. The elastic reaction force generated by it drives the slider 16 to reset through the curved rod 14, and then drives the rotating frame 9 to reset, realizing the preparation for centering and straightening the next wooden board.

[0015] The top end of the central shaft 12 is rotatably connected with a square plate 15. The left and right ends of the square plate 15 are rotatably connected to the adjacent sides of the adjacent curved rods 14. When the rotating frame 9 is pressed and opened, it is pulled by the curved rod 14 to rotate, thereby pulling the torsion spring 13 to unfold; during the reset process of the components, it rotates with the reverse rotation of the curved rod 14 to assist in completing the reset operation. The end of the curved rod 14 far from the central shaft 12 is rotatably connected with a slider 16. The slider 16 converts the rotational motion of the curved rod 14 into linear sliding and transmits it to the rotating frame 9 through the first connecting rod 17 and the second connecting rod 18, precisely controlling the movement of the rotating frame 9 to achieve centering and straightening of the wooden board. The left end of the slider 16 is rotatably connected with the first connecting rod 17, and the left end of the first connecting rod 17 is rotatably connected with the second connecting rod 18. Cooperating with the first connecting rod 17, during the centering and straightening of the wooden board and the adjustment of the inclination angle of the rotating frame 9, the movement of the slider 16 is transmitted to the rotating frame 9 to achieve precise control of the movement and angle of the rotating frame 9.

[0016] Reference Figure 5 and Figure 6 , limiting pieces for limiting the position of the slider 16 are arranged on the front and rear sides of the sliding sleeve 11. The limiting pieces include support bars 19. The top ends of the support bars 19 are slidably connected to the top end of the fixed plate 8. The support bars 19 are fixedly connected to the front and rear sides of the sliding sleeve 11. The support bars 19 provide stable sliding support for the slider 16 to ensure that the slider 16 moves within the specified track. The top ends of the support bars 19 are fixedly connected with positioning blocks 20. There are four positioning blocks 20, and there are two positioning blocks 20 at the front and rear positions on one support bar 19 respectively.

[0017] The top ends of the positioning blocks 20 are slidably connected to the top end of the fixed plate 8. The middle parts of the adjacent positioning blocks 20 are fixedly connected with limiting rods 21. The middle part of the slider 16 is slidably connected to the outside of the limiting rods 21. The bottom end of the slider 16 is slidably connected to the top end of the support bar 19. When the device is working, the movement track of the slider 16 is limited, so that the slider 16 can only slide along the direction of the limiting rod 21, ensuring the accuracy and stability of the movement of the slider 16.

[0018] Reference Figure 7, on both the front and rear sides of the adjacent turntable 9, a plurality of push shafts 22 are rotatably connected. On the one hand, as a component for triggering the movement of the turntable 9, the push shaft 22 starts the centering and straightening process of the turntable 9 through the extrusion of the wooden board. On the other hand, during the movement and cleaning of the wooden board, by rolling itself, it reduces the moving resistance of the wooden board and improves the cleaning effect. A mounting rod 23 is fixedly connected to the top end of the side of the turntable 9 close to the stacking rack 2. An installation block 24 is slidably connected to the outside of the mounting rod 23. A cleaning shaft 25 is detachably connected between the installation block 24 and the side of the turntable 9 close to the stacking rack 2, which supports the cleaning shaft 25 to ensure its stable position when cleaning the side of the wood. At the same time, its sliding connection design facilitates the disassembly and replacement of the cleaning shaft 25, which is convenient for maintenance and improves the practicality of the device.

[0019] Reference Figure 2 , and Figure 8 , on the upper and lower sides of the left end of the sliding sleeve 11, a first toothed head rod 26 is rotatably connected, and on the upper and lower sides of the left end of the sliding sleeve 11, a second toothed head rod 27 is rotatably connected. The teeth at the end of the first toothed head rod 26 close to the sliding sleeve 11 are meshed with the teeth at the end of the second toothed head rod 27 close to the sliding sleeve 11. The second toothed head rod 27 and the first toothed head rod 26 play a role in transmitting motion and force in the tilt angle adjustment transmission chain. Cooperating with components such as the first toothed head rod 26, they precisely control the movement of the sliding sleeve 11 to ensure the accuracy of the tilt angle adjustment of the turntable 9.

[0020] A fourth toothed head rod 29 is rotatably connected to the end of the first toothed head rod 26 far from the mounting frame 10. A third toothed head rod 28 is fixedly connected to the middle of the end of the second toothed head rod 27 far from the sliding sleeve 11. The third toothed head rod 28 and the end of the second toothed head rod 27 far from the sliding sleeve 11 are rotatably connected to the middle of the left side of the mounting frame 10. The teeth at the end of the third toothed head rod 28 far from the sliding sleeve 11 are meshed with the teeth at the end of the fourth toothed head rod 29 far from the sliding sleeve 11. In the tilt angle adjustment system of the turntable 9, as a key transmission connection component, it transmits the rotational motion of the fourth toothed head rod 29 to the second toothed head rod 27 to realize the pushing of the sliding sleeve 11 and ensure the realization of the tilt angle adjustment function.

[0021] A handle 30 is fixedly connected to the middle of the end of the fourth toothed head rod 29 far from the sliding sleeve 11. The outside of the handle 30 is rotatably connected to the middle of the left side of the mounting frame 10. When the user shakes the handle 30, it drives the fourth toothed head rod 29 to rotate. Through meshing with the third toothed head rod 28, it drives the third toothed head rod 28, the second toothed head rod 27, and the first toothed head rod 26 to rotate, pushing the sliding sleeve 11 to move and adjusting the tilt angle of the turntable 9.

[0022] Working principle: During use, by connecting to an external start control terminal, conveyor belt 1 is started for rolling transmission. Subsequently, a wooden board is placed on conveyor belt 1 and moves along conveyor belt 1. When the wooden board reaches the position of the turntable 9, both ends of it will squeeze the push shaft 22 of the turntable 9, causing the push shaft 22 to roll, and at the same time, the turntable 9 rotates and opens due to the extrusion of the wooden board. After the turntable 9 is pressed, the front and rear sliders 16 are driven by link 2 18 and link 1 17 to slide in opposite directions to the outside. The synchronous sliding of the sliders 16 further drives the relative crank 14 to rotate and pulls the square plate 15 to rotate, while pulling the torsion spring 13 to unfold. The elastic reaction force of the torsion spring 13 drives the sliders 16 to reset through the relative crank 14. The sliders 16 drive the turntable 9 through link 1 17 and link 2 18 to hold both sides of the moving wooden board on conveyor belt 1, achieving centering and straightening of the transported wooden board, and avoiding problems such as uneven and loose stacking caused by the offset of the wood position. After the wooden board moves centrally, the push shaft 22 and the cleaning shaft 25 on the opposite side of the turntable 9 will also perform rolling cleaning on the side of the wood, reducing the dead corner position of the wooden board cleaning.

[0023] Finally, when the wooden board moves to the end of conveyor belt 1, the wooden board will move to the top of the stacking roller pad 5. The hydraulic cylinder 4 controls the telescopic movement of the stacking roller pad 5 to drive the wooden board to rise and squeeze the support rod 7 to make it rotate. Subsequently, at the stacking position, when the top of the support rod 7 stacks to a fixed number, the hydraulic cylinder 4 drives the stacking roller pad 5 to lift the stacked wooden board, and then starts the rollers on the stacking roller pad 5 to transport the stacked wooden board to conveyor belt 2 3, so that conveyor belt 2 3 moves the stacked wooden board to the next process.

[0024] At the position of the mounting frame 10, an adjusting component is also provided. The user shakes the handle 30 to drive the fourth tooth head rod 29 to mesh with the third tooth head rod 28, making the fourth tooth head rod 29 and the third tooth head rod 28 rotate synchronously, and pushing the first tooth head rod 26 to mesh with the second tooth head rod 27 through the rotating shaft at the other end, realizing the square expansion of the first tooth head rod 26, the second tooth head rod 27, the third tooth head rod 28, and the fourth tooth head rod 29, pushing the sliding sleeve 11 and the support bar 19 to move to the right as a whole, making the included angles of link 1 17 and link 2 18 smaller, and indirectly adjusting the overall inclination angle of the two turntables 9. According to the characteristics of the wood and the transmission requirements, flexibly adjusting the inclination angle can make the movement of the wood on the conveyor belt more stable and smooth.
