Detailed Embodiments

[0025] Next, in combination with Figures 1 - 6A specific embodiment of the present invention will be elaborated in detail.

[0026] Refer to Figures 1 - 6 , a waste recycling and processing device for wood production and processing, including a frame 1, on which there are a transportation area for wood, a cutting chamber, a crushing chamber and a discharging chamber.

[0027] Refer to Figure 1 , in the transportation area of the frame 1, a first roller 6 is connected through a first straight rod 61, and a second roller 9 is connected through a second straight rod 91 on the frame 1. The purpose is to utilize the rolling cooperation of the first roller 6 and the second roller 9 to realize the clamping and transportation of the wood to be processed, that is, the wood is inserted between the first roller 6 and the second roller 9, and the wood is transported to the cutting chamber through the rotation of the first roller 6 and the second roller 9. To facilitate the strong clamping action of the first roller 6 and the second roller 9 on the wood and at the same time generate a pushing force on the wood, the first roller 6 and the second roller 9 are both provided with evenly distributed convex dies.

[0028] The transportation of the wood is based on the rotation of the first roller 6 and the second roller 9. Conventionally, two separate power sources can be set to drive the first roller 6 and the second roller 9 to rotate respectively. In this device, one power source is set to realize the rotation of the above two. Specifically: a first motor 4 is installed on the frame 1, the first motor 4 is a double-shaft motor, and the first motor 4 drives the first straight rod 61 and the second straight rod 91 to rotate through a first belt 7 and a second belt 13 respectively, aiming to realize the rotation of the first roller 6 and the second roller 9 through the transmission of the first belt 7 and the second belt 13.

[0029] Refer to Figure 1 , to realize the directional transportation of the wood, the first roller 6 and the second roller 9 should maintain relative rotation. Therefore, this device realizes it through a commutation component. The commutation component includes a rotatable first rotating column 11, a second gear 12 is key-connected to the first rotating column 11, a first gear 10 is key-connected to the second straight rod 91, and the first gear 10 and the second gear 12 are meshed. That is, through the meshing of the first gear 10 and the second gear 12, the relative rotation of the first roller 6 and the second roller 9 is realized. The first rotating column 11 is connected to the output shaft of the first motor 4 through the second belt 13, and the first straight rod 61 is connected to the output shaft of the first motor 4 through the first belt 7.

[0030] When the first motor 4 operates, due to the existence of the first belt 7 and the second belt 13, the first straight rod 61 and the first rotating column 11 rotate, the first roller 6 is controlled to rotate forward, and under the cooperation of the first gear 10 and the second gear 12, the second roller 9 is controlled to rotate reversely, and then the convex dies of the first roller 6 and the second roller 9 form a mechanical bite on the wood and transport it to the cutting chamber directionally.

[0031] As described in the background art, conventional wood production and processing waste treatment devices only process wood waste of specific sizes. In order for this device to adapt to wood of different thicknesses, the following settings are made. Two symmetrically distributed rotating frames 2 are connected to the frame 1. A second straight rod 91 is connected between the two rotating frames 2. A first rotating column 11 is connected to the outer wall of the rotating frame 2. That is, the first roller 6 is stably on the frame 1, and the second straight rod 91 can rotate with the rotating frame 2. The purpose is to flexibly adjust the distance from the first roller 6 by the rotation of the second roller 9 to adapt to wood of different thicknesses.

[0032] Reference Figure 1 , a first spring 3 is compressed between the rotating frame 2 and the frame 1. The purposes are, first, to realize the rotation reset action of the rotating frame 2 through the first spring 3, and second, to realize the effect of the rotating frame 2 tightly pressing the wood through the first spring 3.

[0033] Wood of different thicknesses is inserted between the first roller 6 and the second roller 9. The wood is squeezed by the first roller 6 and the second roller 9. The second roller 9 is pressed upward and lifted. The rotating frame 2 and the first rotating column 11 are controlled to rotate upward by a certain angle. The first spring 3 is stretched. The wood is clamped by the first roller 6 and the second roller 9. The first motor 4 is started. Due to the existence of the first belt 7 and the second belt 13, the first straight rod 61 and the first rotating column 11 rotate. The first roller 6 is controlled to rotate forward. Under the cooperation of the first gear 10 and the second gear 12, the second roller 9 is controlled to rotate in reverse. The wood is directionally conveyed to the cutting cavity.

[0034] Reference Figure 6 , to facilitate the insertion of wood between the first roller 6 and the second roller 9, the convex dies of the first roller 6 and the second roller 9 should be in a non-contact state, that is, there is a gap between the convex dies of the first roller 6 and the second roller 9. This device is realized through the following settings. A stop plate 33 is fixedly connected to the frame 1. There are two cavities on the stop plate 33. A first lead screw 31 is connected in the upper cavity. An upper baffle 32 is threadedly connected to the first lead screw 31. A second lead screw 35 is connected in the lower cavity of the stop plate 33. A lower baffle 34 is threadedly connected to the second lead screw 35. Adjusting nuts are provided at the ends of the first lead screw 31 and the second lead screw 35. That is, by manually adjusting the adjusting nuts, the first lead screw 31 and the second lead screw 35 can be driven to rotate. The upper baffle 32 and the lower baffle 34 are respectively in contact with the upper and lower sides of the rotating frame 2. The purpose is to clamp the rotating frame 2 through the upper baffle 32 and the lower baffle 34.

[0035] Initially, according to the thickness of the wood, adjust the adjusting nut at the end of the second lead screw 35. Rotate the second lead screw 35, and the lower baffle 34 moves upward. Adjust the adjusting nut at the end of the first lead screw 31. Rotate the first lead screw 31, and the upper baffle 32 moves upward until the distance between the upper baffle 32 and the lower baffle 34 is slightly greater than the thickness of the wood, that is, the moving distance of the rotating frame 2 is limited by the upper baffle 32 and the lower baffle 34. Thus, the moving distance of the second roller 9 is limited, aiming to facilitate the wood to smoothly penetrate between the first roller 6 and the second roller 9. Particularly, by moving the upper baffle 32 and the lower baffle 34, the rotating frame 2 can be stably fixed at a certain height, thereby ensuring that there is always a gap between the second roller 9 and the first roller 6, that is, the second roller 9 does not contact the first roller 6.

[0036] Reference Figure 2 , during the above process, since the rotating frame 2 and the first rotating column 11 are controlled to rotate upward, to keep the second belt 13 always in a taut state and ensure that the power source of the first motor 4 is transmitted to the first rotating column 11 through the second belt 13, a fixed frame 8 is fixedly connected to the frame 1. A chute is opened on the fixed frame 8, and a slider 81 is slidably connected in the chute. A second spring 83 is compressed between the slider 81 and the fixed frame 8. A pulley 82 is rotatably connected to the slider 81. The second belt 13 respectively bypasses the output shaft of the first motor 4 with power input, the first rotating column 11 with power output, and the pulley 82 for adjusting the tension. That is, due to the existence of the second spring 83, it is ensured that the second belt 13 is not affected by the rotation actions of the rotating frame 2 and the first rotating column 11 and is always in a taut state. Based on the taut state of the second belt 13, a downward pulling force is exerted on the first rotating column 11. Furthermore, a downward pulling force is exerted on the second roller 9. At the same time, under the action of the first spring 3 and the self-gravity of the second roller 9, the second roller 9 always presses on the wood. Thus, the first roller 6 and the second roller 9 always maintain a clamping action on the wood.

[0037] Reference Figure 2 , for the convenience of installing the slider 81 and the second spring 83, an end plate 80 is detachably installed at the end of the fixed frame 8 through a fastener to block the chute.

[0038] Reference Figure 1 and Figure 3, the cutting chamber of the frame 1 includes a movable frame 16 that can move up and down. A chain saw 18 for cutting wood is connected to the movable frame 16 through a connecting bracket 17. The purpose is to realize the movement of the chain saw 18 through the movement of the movable frame 16 and then complete the wood cutting action. To realize the movement of the movable frame 16 and avoid repeated setting of power sources, the power source for the movement of the movable frame 16 is combined with the first motor 4. A connecting disk 14 is fixedly connected to both output shafts of the first motor 4. A support rod 15 is pivoted on the connecting disk 14, and the support rod 15 is pivoted to the movable frame 16. The connecting disk 14, the support rod 15, and the movable frame 16 together form a connecting rod swing structure, that is: the rotational movement of the connecting disk 14 is converted into the up and down movement of the movable frame 16 through the support rod 15. A guiding member 5 is fixedly connected to the frame 1, and the movable frame 16 is slidably connected to the guiding member 5. The purpose is to guide the movement of the movable frame 16 up and down through the guiding member 5.

[0039] As the first motor 4 operates, the connecting disk 14 rotates, the support rod 15 is controlled to swing. Based on the presence of the guiding member 5, the movable frame 16 is controlled to move up and down, and the chain saw 18 contacts the wood to perform the cutting action.

[0040] Specifically, the cutting chamber of the frame 1 is a triangular space, that is, the bottom is an inclined plane. The purpose is to facilitate the chain saw 18 to penetrate and cut the wood, that is: the first roller 6 and the second roller 9 clamp one end of the wood, and when the wood moves into the cutting chamber, a section is in a suspended state. The chain saw 18 vertically drops and contacts the inclined plane to ensure that the wood can be completely cut.

[0041] Reference Figure 5 , the crushing chamber of the frame 1 includes a wire mesh frame 23 installed inside the frame 1. A rotatable rotating shaft 21 is provided inside the wire mesh frame 23. A number of crushing cutters 22 are fixedly connected to the rotating shaft 21. The cut wood realizes the crushing effect through the cooperation of the rotating shaft 21 and the crushing cutters 22. To realize the rotation of the rotating shaft 21, a second motor 20 is installed on the frame 1, and the output shaft of the second motor 20 is connected to the rotating shaft 21, that is, the rotating shaft 21 penetrates the frame 1 and extends to the outside and is connected to the output shaft of the second motor 20. The cut wood slides down onto the wire mesh frame 23 through the guiding of the inclined plate. The second motor 20 operates, the rotating shaft 21 rotates, and the crushing cutters 22 are controlled to rotate to crush the wood.

[0042] To facilitate the installation of the wire mesh frame 23 and the rotating shaft 21 and subsequent maintenance, a maintenance plate 19 is detachably installed on the crushing chamber of the frame 1.

[0043] After the wood is crushed, it falls into the discharge chamber by its own gravity. The discharge chamber of the frame 1 is arranged at the bottom of the wire mesh frame 23. A number of micropores with fixed sizes are opened on the wire mesh frame 23. The purpose is that the wood can only fall into the discharge chamber from the micropores of the wire mesh frame 23 after being crushed to the standard.

[0044] Reference Figure 4 Figure 4 , a discharge port is formed on the discharge cavity of the frame 1, and a rotating plate 24 is connected to the discharge port. The rotating plate 24 is provided with uniformly distributed baffles. The purposes are as follows: one is to achieve the effect of uniform discharging through the rotation of the rotating plate 24, and the other is that the baffles of the rotating plate 24 block the discharge port to achieve the effect of a baffle, avoiding waste of raw materials.

[0045] To realize the rotation of the rotating plate 24, the device combines the power source for rotating the rotating plate 24 with the second motor 20. A third gear 25 is fixedly connected to the rotating plate 24, a second rotating column 26 is rotatably connected to the frame 1, a missing gear 27 is fixedly connected to the second rotating column 26, the missing gear 27 cooperates with the third gear 25, and the second rotating column 26 is connected to the rotating shaft 21 through a third belt 28. The aim is to transmit the power source of the second motor 20 to the rotating plate 24 through the transmission of the third belt 28.

[0046] Initially, the baffle of the rotating plate 24 blocks the discharge port. When the second motor 20 operates, the rotating shaft 21 rotates, and the crushing tool 22 is controlled to rotate to crush the wood. The crushed wood falls on the discharge port of the discharge cavity through the micropores on the wire mesh frame 23. Due to the existence of the third belt 28, the second rotating column 26 is controlled to rotate, and the missing gear 27 rotates. Particularly, after the missing gear 27 rotates one circle, it meshes with the third gear 25, thereby driving the third gear 25 to rotate a fixed angle, and then the rotating plate 24 and the baffle rotate a fixed angle, and the crushed wood thus falls.

[0047] During this process, the discharging action of the rotation of the rotating plate 24 and the baffle lags behind the rotation of the rotating shaft 21 and the crushing action of the crushing tool 22, aiming to realize the process of first crushing and then discharging the wood. At the same time, the baffle of the rotating plate 24 is consistent with the caliber of the discharge port, ensuring that the discharge cavity is in a sealed state before the rotating plate 24 and the baffle rotate, avoiding the direct dropping of the crushed wood out of the discharge port and causing waste. At the same time, through the intermittent transmission cooperation of the missing gear 27 and the third gear 25, the rotating plate 24 and the baffle rotate intermittently by a fixed angle, and the effect of quantitative discharging can be achieved, avoiding the problem of uneven accumulation caused by one-time discharging.

[0048] Considering that during the crushing process of wood, due to the presence of cellulose, hemicellulose, lignin, organic substances (VOCs) and other potentially harmful components in the wood, harmful gases will be generated after crushing. Therefore, the device collects and treats the harmful gases by arranging a connecting pipe 29 on the frame 1. The connecting pipe 29 is detachably installed on the frame 1, that is, the connecting pipe 29 is installed on the crushing cavity of the frame 1. The harmful gases are extracted from the frame 1 through the connecting pipe 29 and then treated to avoid damage to the environment.

[0049] A soft curtain 30 is also installed between the cutting cavity and the crushing cavity of the frame 1 to prevent the dust generated in the crushing cavity from floating into the cutting cavity during the operation of the crushing cavity. In addition, the soft curtain 30 can play a certain blocking effect on the wood sliding on the inclined plate, avoiding the wood from sliding too fast and hitting the crushing components in the crushing cavity.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
