Description

Technical Field

[0001] This invention relates to the field of wood processing feeding technology, and more particularly to a feeding mechanism for wood processing. Background Technology

[0002] In the timber processing industry, the processing of timber boards typically involves multiple stages, including initial cutting, stacking and storage, orderly feeding, and subsequent processing. Among these, the feeding stage, as a crucial process connecting initial cutting and subsequent processing, directly impacts overall processing efficiency and precision. After cutting, timber boards must be neatly stacked in a dedicated stacking rack due to processing rhythm and storage requirements. Once the subsequent processing equipment is ready, the stacked timber boards are then fed one by one in an orderly manner to the feeding end of the processing equipment to ensure the continuous execution of subsequent sawing, sanding, carving, and other processing steps. During this process, the feeding mechanism must facilitate the transition of timber boards from a stacked state to individual conveying, and then to stable delivery to the processing equipment. Its smooth operation and coordination are critical to the overall capacity of the production line.

[0003] However, existing timber feeding devices have some shortcomings in practical applications.

[0004] On the one hand, the existing equipment operates with each process operating independently. For example, stacking wood panels requires manual labor or separate equipment, and feeding a single panel relies on a different drive structure. There is a lack of effective linkage between feeding and subsequent transfer, resulting in poor coordination between processes. This separate design is prone to problems where the feeding speed is not synchronized with the processing equipment's requirements. Either feeding too fast causes wood panels to accumulate, or feeding too slow causes the processing equipment to idle, seriously affecting processing efficiency.

[0005] On the other hand, wood panels often need to be grouped into specific quantities during the feeding process to control the processing batches and finished product quantities during subsequent processing. However, existing equipment lacks a linked wood grouping component, and the grouping work relies on manual counting by workers. This not only increases the difficulty and labor intensity of workers' operations, but also makes it easy for counting errors to occur due to human negligence, resulting in inaccurate grouping. This, in turn, affects the consistency of subsequent processing quality and finished product specifications, leading to unnecessary material waste and increased costs for enterprises. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a feeding mechanism for wood processing, which overcomes the shortcomings of the prior art and effectively solves the problems of poor process coordination, asynchronous feeding, and the need for manual counting and grouping.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A feeding mechanism for wood processing includes a feeding frame, a stacking rack at one end of the feeding frame, and a main shaft at the bottom of the stacking rack. A reducer is fixedly connected to the outer wall of one end of the main shaft via a coupling, and adjacent rotating arms are fixedly connected to the outer wall of the main shaft via screws.

A traction rod is installed through the two push plates, and a traction ring is fixedly connected to the bottom of one side of the outer wall of the stacking rack via screws, with the traction rod tightly attached to the inner wall of the traction ring. The top outer wall of the feeding rack is fixedly connected to adjacent frames on one side of the stacking rack by screws, and a feeding roller is rotatably connected between the two frames by bearings. A pulley assembly is installed between the outer wall of one end of the feeding roller and the main shaft. A conveyor is installed on one side of the top outer wall of the feeding rack on the frame, and a mounting frame is fixedly connected to the top outer wall of the feeding rack on the side of the conveyor by screws. A wood grouping assembly is provided on the outer wall of the mounting frame.

[0008] Preferably, the traction ring includes an arc-shaped groove and a horizontal groove, wherein the arc-shaped groove is located on the bottom inner wall of the traction ring, the horizontal groove is located on the top inner wall of the traction ring, and the traction rod is in close contact with the inner wall of the horizontal groove.

[0009] Preferably, the timber grouping assembly includes a connecting rod, an internal threaded sleeve, a lead screw, a traction head, a swing plate, a swing column, and a pressure plate frame. The connecting rod is disposed through the inner wall of the mounting frame. The internal threaded sleeve is welded to the outer wall of one end of the connecting rod. The lead screw is screwed to the inner wall of the internal threaded sleeve. The traction head is welded to the outer wall of the other end of the connecting rod. The swing plate is slidably connected to the outer wall of one end of the traction head. The swing column is rotatably connected to the top inner wall of the swing plate. The pressure plate frame is welded to the outer wall of the swing column and is disposed on the top of the conveyor.

[0010] Preferably, the wood grouping assembly further includes a second spring and a torsion spring, wherein the second spring is fixedly connected between the connecting rod and the mounting bracket, and the torsion spring is fixedly connected between the swing plate and the swing column.

[0011] Preferably, the outer wall of one end of the traction rod is tightly attached to the outer wall of one end of the lead screw.

[0012] Preferably, the pulley assembly includes adjacent pulleys and a conveyor belt meshing between the two pulleys, wherein the two pulleys are distributed and mounted on the outer walls of the main shaft and the feed roller.

[0013] Preferably, the bottom outer wall of the stacking rack has adjacent sliding grooves, and the push plate is slidably connected to the inner wall of the sliding groove. The inside of the stacking rack is stacked with equally spaced wood boards, and the push plate is in close contact with the outer wall of one side of the bottom wood board inside the stacking rack.

[0014] Preferably, a motor mounting base is welded to one outer wall of the feeding rack, and the reducer is fixedly connected to the top outer wall of the motor mounting base by screws. Angle brackets are fixedly connected between the stacking rack and the frame by screws, and a baffle for blocking wood boards is welded to the outer wall of the other end of the feeding rack.

[0015] Preferably, a slider is slidably connected to the inner wall of the frame, and a column is welded to the top outer wall of the slider. The column is disposed through the top inner wall of the frame. A third spring is fixedly connected between the slider and the column, and a top pressure roller is rotatably connected between the two sliders through a bearing.

[0016] Preferably, a side plate is welded to one side of the outer wall of the conveyor, and a connecting rod is installed through the inner wall of the side plate.

[0017] The beneficial effects of this invention are as follows: 1. The feeding mechanism for wood processing of the present invention has a main shaft that drives a rotating arm to rotate under the drive of a reducer. The rotating arm, through the sliding cooperation between the sliding sleeve and the rotating column, combined with the elastic force of the first spring, can push the push plate to move stably. At the same time, the traction rod slides in the arc groove and horizontal groove of the traction ring, which can accurately control the movement trajectory of the push plate. In the arc groove stage, the push plate moves away from the wood board, while in the horizontal groove stage, the push plate is close to the bottom wood board and pushes it to move, realizing the feeding of wood boards one by one without the need for an additional drive structure, thus improving the process coordination and feeding synchronization. 2. The feeding mechanism for wood processing of the present invention has a feeding roller in the frame that is linked to the main shaft through a pulley set. When the main shaft rotates, it can drive the feeding roller to rotate synchronously. There is no need to set a separate drive source for the feeding roller, which ensures that the movement of the feeding roller and the push plate is synchronized. The conveyor receives the wood boards transferred by the feeding roller to realize continuous conveying. The wood grouping component is linked to the main shaft through a traction rod, which can complete the grouping synchronously during the conveying of wood boards without manual intervention. This solves the problem of separation of feeding and grouping in existing devices, and builds a linkage system of continuous conveying and automatic grouping of wood boards, which further strengthens the coordination between processes. 3. In the feeding mechanism for wood processing of the present invention, when the traction rod slides in the horizontal groove, it contacts and pushes the lead screw. The lead screw drives the connecting rod to move through the internal threaded sleeve. The traction head at one end of the connecting rod drives the swing plate to tilt, thereby driving the swing column and the pressure plate frame to squeeze the wood boards on the conveyor downward to form groups. The second spring can pull the connecting rod to reset after the traction rod leaves the lead screw. The torsion spring drives the swing plate, swing column and pressure plate frame to reset, preparing for the next grouping. Through this linkage structure, the pressure plate frame can intermittently squeeze the wood boards as the main shaft rotates, realizing grouping according to a fixed number, eliminating the need for workers to count, reducing labor intensity and ensuring grouping accuracy.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-8 Example 1: A feeding mechanism for wood processing includes a feeding frame 1. A stacking rack 2 is provided at one end of the feeding frame 1, and a main shaft 3 is provided at the bottom of the stacking rack 2. A reducer 4 is fixedly connected to the outer wall of one end of the main shaft 3 via a coupling. Adjacent rotating arms 5 are fixedly connected to the outer wall of the main shaft 3 via screws. A sliding sleeve 6 is welded to the top of one side of the outer wall of each rotating arm 5, and a rotating column 7 is slidably connected to the inner wall of the sliding sleeve 6. A first spring 8 is fixedly connected between the rotating column 7 and the rotating arm 5. Furthermore, a push plate 9 is welded to the top outer wall of the rotating column 7, and a traction rod 10 is installed through the two push plates 9. A traction ring 11 is fixedly connected to the bottom of one side outer wall of the stacking rack 2 by screws, and the traction rod 10 is tightly attached to the inner wall of the traction ring 11. The traction ring 11 includes an arc groove 111 and a horizontal groove 112. The arc groove 111 is located on the bottom inner wall of the traction ring 11, and the horizontal groove 112 is located on the top inner wall of the traction ring 11. The traction rod 10 is tightly attached to the inner wall of the horizontal groove 112.

[0022] Through the above scheme, the feeding rack 1 provides a stable support foundation for the entire mechanism, the stacking rack 2 is used to stack the wood boards to be processed to ensure that the wood boards are stored in an orderly manner, the main shaft 3 achieves stable rotation under the drive of the reducer 4, the rotating arm 5 rotates synchronously with the main shaft 3 to provide a power transmission path for the subsequent movement of the push plate 9, the sliding sleeve 6 provides a sliding guide for the rotating column 7 so that the rotating column 7 can only move along the axial direction of the sliding sleeve 6 to avoid deviation, the first spring 8 uses elastic force to push the rotating column 7 out of the sliding sleeve 6 at a certain stage, thereby driving the push plate 9 to stick to the wood board. The push plate 9 directly contacts the bottom wood board and is responsible for pushing the wood board to move. The traction rod 10 connects two push plates 9 to ensure that their movements are synchronized. At the same time, its sliding within the traction ring 11 can precisely control the movement trajectory of the push plates 9: the arc groove 111 stage keeps the push plates 9 away from the wood board to prevent interference with the falling of the upper wood board, while the horizontal groove 112 stage keeps the push plates 9 pushing the bottom wood board, realizing single-piece feeding. The overall structure replaces manual feeding with mechanical linkage, improving feeding efficiency and synchronization.

[0023] In this embodiment, the main shaft 3 drives the rotating arm 5 to rotate under the drive of the reducer 4. The rotating arm 5, through the sliding cooperation between the sliding sleeve 6 and the rotating column 7, combined with the elastic force of the first spring 8, can push the push plate 9 to move stably. At the same time, the traction rod 10 slides in the arc groove 111 and the horizontal groove 112 of the traction ring 11, which can accurately control the movement trajectory of the push plate 9. The arc groove 111 stage makes the push plate 9 move away from the wood board, while the horizontal groove 112 stage makes the push plate 9 stick to the bottom wood board and push it to move, realizing the single-piece feeding of the wood board without the need for an additional drive structure, thus improving the process coordination and feeding synchronization.

[0024] In embodiment 2, the top outer wall of the feeding rack 1 is fixedly connected to adjacent frames 12 on one side of the stacking rack 2 by screws, and the two frames 12 are rotatably connected by a feeding roller 13 through a bearing. A pulley group 14 is installed between the outer wall of one end of the feeding roller 13 and the main shaft 3. A conveyor 15 is installed on one side of the top outer wall of the feeding rack 1 located on the frame 12, and a mounting frame 16 is fixedly connected to the top outer wall of the feeding rack 1 on one side of the conveyor 15 by screws. A wood grouping assembly 17 is provided on the outer wall of the mounting frame 16, and one end of the outer wall of the traction rod 10 is tightly attached to one end of the outer wall of the lead screw 173.

[0025] Through the above scheme, the frame 12 provides installation and support space for components such as the feeding roller 13 and the top pressure roller 24, ensuring the stability of each component's position. The feeding roller 13 receives and transfers the wood board by rotating, conveying the wood board pushed by the push plate 9 to the conveyor 15. The pulley group 14 consists of two pulleys and a conveyor belt, realizing the power transmission between the main shaft 3 and the feeding roller 13, so that the rotation speed of the feeding roller 13 is synchronized with that of the main shaft 3, avoiding the accumulation or separation of the wood board during the transfer process. The conveyor 15 receives the wood board transferred by the feeding roller 13 and conveys the wood board to the subsequent processing equipment through continuous operation, realizing the continuity of the feeding process. The tight fit between the traction rod 10 and the lead screw 173 realizes the linkage between the feeding action driven by the main shaft 3 and the grouping action of the wood grouping component 17, without the need to set up an additional drive source for the grouping component, simplifying the structure while ensuring the synchronization of feeding and grouping.

[0026] In this embodiment, the feeding roller 13 inside the frame 12 is linked to the main shaft 3 through the pulley group 14. When the main shaft 3 rotates, it can synchronously drive the feeding roller 13 to rotate, eliminating the need to set a separate drive source for the feeding roller 13. This ensures that the feeding roller 13 and the push plate 9 move synchronously. The conveyor 15 receives the wood boards transmitted by the feeding roller 13 and realizes continuous conveying. The wood grouping component 17 is linked to the main shaft 3 through the traction rod 10. It can synchronously complete the grouping during the wood board conveying process without manual intervention. This solves the problem of separation of feeding and grouping in the existing device and builds a linkage system of continuous wood board conveying and automatic grouping, further strengthening the coordination between processes.

[0027] In embodiment three, the timber grouping assembly 17 includes a connecting rod 171, an internal threaded sleeve 172, a lead screw 173, a traction head 174, a swing plate 175, a swing column 176, and a pressure plate frame 177. The connecting rod 171 is disposed through the inner wall of the mounting frame 16. The internal threaded sleeve 172 is welded to the outer wall of one end of the connecting rod 171. The lead screw 173 is screwed to the inner wall of the internal threaded sleeve 172. The traction head 174 is welded to the outer wall of the other end of the connecting rod 171. The swing plate 175 is slidably connected. On one end of the outer wall of the traction head 174, the swing column 176 is rotatably connected to the top inner wall of the swing plate 175, and the pressure plate frame 177 is welded to the outer wall of the swing column 176 and is located on the top of the conveyor 15. The timber grouping assembly 17 also includes a second spring 178 and a torsion spring 179, wherein the second spring 178 is fixedly connected between the connecting rod 171 and the mounting bracket 16, and the torsion spring 179 is fixedly connected between the swing plate 175 and the swing column 176.

[0028] Through the above scheme, the connecting rod 171 can slide along the inner wall of the mounting frame 16 under the push of the lead screw 173 to transmit power. The inner threaded sleeve 172 is threadedly connected to the lead screw 173, and at the same time, it is convenient to adjust the relative position of the lead screw 173 and the connecting rod 171 to adapt to the grouping requirements of different specifications of wood boards. The traction head 174 moves with the connecting rod 171 and drives the swing plate 175 to tilt through the sliding cooperation with the swing plate 175. When the swing plate 175 tilts, it drives the swing column 176 to rotate, providing power for the downward pressing action of the pressure plate frame 177. The swing column 176 serves as the rotation fulcrum to realize the connection and power transmission between the swing plate 175 and the pressure plate frame 177. When the pressure plate frame 177 presses down, it squeezes the wood boards on the conveyor 15 to form groups, realizing the grouping of wood boards according to a fixed number. After the traction rod 10 leaves the lead screw 173, the second spring 178 pulls the connecting rod 171 back to its original position through elastic force, preparing for the next grouping. The torsion spring 179 drives the swing plate 175, swing column 176 and pressure plate frame 177 to reset after the swing plate 175 loses the thrust of the traction head 174, ensuring that the grouping action can be repeated without manual reset, reducing the difficulty of operation.

[0029] In this embodiment, when the traction rod 10 slides in the horizontal groove 112, it contacts and pushes the lead screw 173. The lead screw 173 drives the connecting rod 171 to move through the internal threaded sleeve 172. The traction head 174 at one end of the connecting rod 171 drives the swing plate 175 to tilt, thereby driving the swing column 176 and the pressure plate frame 177 to squeeze the wood boards on the conveyor 15 downward to form groups. The second spring 178 can pull the connecting rod 171 to reset after the traction rod 10 leaves the lead screw 173. The torsion spring 179 drives the swing plate 175, the swing column 176 and the pressure plate frame 177 to reset, preparing for the next grouping. Through this linkage structure, the pressure plate frame 177 can intermittently squeeze the wood boards as the main shaft 3 rotates, realizing grouping according to a fixed number, eliminating the need for workers to count, reducing labor intensity and ensuring grouping accuracy.

[0030] The pulley assembly 14 includes adjacent pulleys and a conveyor belt meshing between the two pulleys, wherein the two pulleys are distributed and installed on the outer wall of the main shaft 3 and the feed roller 13.

[0031] With the above scheme, the two pulleys are fixedly connected to the main shaft 3 and the feeding roller 13 respectively, ensuring that when the main shaft 3 rotates, it can drive the conveyor belt to run through the pulleys, thereby driving the feeding roller 13 to rotate synchronously, so that the speed of the feeding roller 13 is consistent with that of the main shaft 3, and thus matches the feeding rhythm of the push plate 9, preventing the wood boards from accumulating at the feeding roller 13 or the conveying from being interrupted, and improving the continuity and reliability of the feeding process.

[0032] The bottom outer wall of the stacking rack 2 is provided with adjacent sliding grooves 18, and the push plate 9 is slidably connected to the inner wall of the sliding groove 18. The stacking rack 2 is filled with equally spaced wooden boards, and the push plate 9 is in close contact with the outer wall of the bottom wooden board inside the stacking rack 2.

[0033] Through the above scheme, the chute 18 provides sliding guidance for the push plate 9, restricting the push plate 9 to move only along the direction of the chute 18, avoiding lateral displacement of the push plate 9 during the process of pushing the wood board, ensuring that the push plate 9 is always aligned with the side of the bottom wood board. The push plate 9 is close to the side of the bottom wood board, and the bottom wood board can be smoothly pushed out of the stacking rack 2 by the pushing force in the horizontal groove 112 stage. At the same time, due to the gravity of the upper wood board, it will automatically fall to the bottom of the stacking rack 2 after the bottom wood board is pushed out, preparing for the next feeding, realizing continuous and single feeding of wood boards without the need for manual replenishment or adjustment of the wood board position.

[0034] A motor mounting base 19 is welded to one side of the outer wall of the feeding rack 1, and the reducer 4 is fixedly connected to the top outer wall of the motor mounting base 19 by screws. Angle brackets 20 are fixedly connected between the stacking rack 2 and the frame 12 by screws, and a baffle for blocking wood boards is welded to the outer wall of the other end of the feeding rack 1.

[0035] Through the above scheme, the motor mounting base 19 provides a stable mounting platform for the reducer 4, the corner bracket 20 connects the stacking rack 2 and the frame 12, enhances the connection strength and stability between the two, ensures the stability of the entire structure, and the baffle at the other end of the feeding rack 1 can block the wood board when it is conveyed to the end, prevent the wood board from slipping off the feeding rack 1 due to inertia, assist workers or subsequent equipment to accurately receive the wood board, and improve the safety and reliability of the feeding process.

[0036] A slider 21 is slidably connected to the inner wall of the frame 12, and a column 22 is welded to the top outer wall of the slider 21. The column 22 is installed through the top inner wall of the frame 12. A third spring 23 is fixedly connected between the slider 21 and the column 22, and a top pressure roller 24 is rotatably connected between the two sliders 21 through a bearing.

[0037] With the above scheme, the slider 21 can slide up and down along the inner wall of the frame 12, providing a moving base for the lifting and lowering of the top pressure roller 24. The column 22 passes through the top of the frame 12, which on the one hand restricts the sliding direction of the slider 21, and on the other hand can indirectly adjust the height of the slider 21 and the top pressure roller 24 by adjusting the position of the column 22. The third spring 23 uses elastic force to always generate a downward push on the slider 21, so that the top pressure roller 24 is in close contact with the top of the wood board. Regardless of whether there are slight differences in the thickness of the wood board, the top pressure roller 24 can adaptively adjust its height to ensure stable pressing force on the wood board. Through the pressing action, the wood board is prevented from tilting or deviating when conveyed on the feeding roller 13, ensuring accurate conveying trajectory of the wood board and improving the conveying quality.

[0038] A side plate 25 is welded to one side of the outer wall of the conveyor 15, and a connecting rod 171 is installed through the inner wall of the side plate 25.

[0039] With the above solution, the side plate 25 is fixed to the conveyor 15 by welding, providing additional support and guidance for the connecting rod 171; the connecting rod 171 passes through the inner wall of the side plate 25, and the side plate 25 can restrict the movement direction of the connecting rod 171, ensuring that the connecting rod 171 can only move in a straight line in the horizontal direction.

[0040] Working principle: First, the wood boards to be processed are evenly stacked inside the stacking rack 2. The stacking rack 2 provides a stable storage space for the wood boards, and the sliding groove 18 at the bottom of the stacking rack 2 can pre-guide and position the push plate 9, so that the push plate 9 can fit tightly against the side of the bottom layer of wood boards inside the stacking rack 2, preparing for subsequent feeding. Then, the reducer 4 is started to drive the main shaft 3, causing the main shaft 3 to rotate stably.

[0041] When the main shaft 3 rotates, it will synchronously drive the two rotating arms 5 fixed on its outer wall to rotate. The sliding sleeve 6 on the rotating arm 5 moves together with the rotating arm 5, thereby driving the rotating column 7 and the push plate 9 to make a circular motion. At this time, the traction rod 10 connecting the two push plates 9 will slide along the inner wall of the traction ring 11 at the bottom of the stacking rack 2. When the traction rod 10 slides in the arc groove 111 of the traction ring 11, the trajectory of the arc groove 111 will force the traction rod 10 to drive the push plate 9 to move away from the wood board. During this stage, the push plate 9 separates from the bottom wood board to avoid interfering with the upper wood board falling to the bottom of the stacking rack 2 under the action of gravity. When the traction rod 10 slides into the horizontal groove 112 of the traction ring 11, the push plate 9 will be pressed tightly against the side of the bottom wood board again, and with the continuous rotation of the rotating arm 5, the bottom wood board will be pushed along the slide 18 towards the feeding roller 13 to realize the single feeding of the wood board. Meanwhile, the main shaft 3 transmits power to the feeding roller 13 inside the frame 12 through the pulley group 14, so that the feeding roller 13 rotates synchronously with the main shaft 3. When the push plate 9 pushes the wood board to the feeding roller 13, the rotation of the feeding roller 13 will drive the wood board to be conveyed towards the conveyor 15. Under the elastic force of the third spring 23, the top pressure roller 24 inside the frame 12 always sticks tightly to the top of the wood board to prevent the wood board from tilting or shifting during conveying, and ensure that the wood board is smoothly transferred to the conveyor 15. The conveyor 15 continues to operate to convey the wood board towards the subsequent processing equipment. As the traction rod 10 slides along the horizontal groove 112, one end of it contacts the outer wall of the lead screw 173 of the wood grouping assembly 17 and pushes the lead screw 173 to move. The lead screw 173 drives the connecting rod 171 to move and stretches the second spring 178. The traction head 174 at the other end of the connecting rod 171 moves with the connecting rod 171, driving the swing plate 175, which is slidably connected to it, to tilt in the direction of movement of the traction head 174. The tilting of the swing plate 175 will cause the pressure plate frame 177 on the outer wall of the swing column 176 to rotate downward. The pressure plate frame 177 squeezes the wood board at the top of the conveyor 15 to form groups. When the traction rod 10 rotates away from the lead screw 173 with the rotating arm 5, the second spring 178 contracts and pulls the connecting rod 171 to reset. At the same time, the torsional spring 179 releases elastic potential energy, driving the swing plate 175, the swing column 176 and the pressure plate frame 177 to reset, preparing for the next grouping. Through this cyclic process, the pressure plate frame 177 rotates with the main shaft 3 to intermittently squeeze the wood boards, thereby achieving automatic grouping of the wood boards without the need for manual counting.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
