Description

Technical Field

[0001] This utility model belongs to the field of double-sided planer technology, specifically relating to a woodworking double-sided planer device. Background Technology

[0002] As a key piece of equipment in the wood processing industry, the double-sided planer's main function is to simultaneously plan the upper and lower surfaces of a wooden board in a single feed, thereby achieving efficient thickness control, flatness, and surface finishing. This equipment typically includes core components such as a feed mechanism, upper and lower cutter shaft assemblies, a clamping device, and a thickness adjustment system. During operation, the wooden board is driven by the feed mechanism and passes sequentially through the high-speed rotating upper and lower cutter shafts, where planing blades mounted on the shafts cut both surfaces of the board.

[0003] When existing double-sided planers plan the upper and lower surfaces of a wooden board, the combined effect of the tool rotation direction and the board feed direction generates a resultant force that causes the board to jump diagonally upwards. This resultant force can be decomposed into a vertically upward component and a horizontally backward component. The vertically upward component can easily cause the board to detach from the worktable, resulting in uneven planing thickness. The horizontally backward component can easily cause the board to move backwards and retract, which not only creates defects such as chipping and gouging marks on the already processed surface but may also lead to safety accidents.

[0004] To address the aforementioned issues, the commonly used solution in existing technologies is to employ a combination mechanism of vertical pressure rollers and conventional feed rollers. The vertically arranged pressure rollers apply pressure to hold the wooden board firmly against the worktable, resisting its tendency to bounce vertically; while the conventional feed rollers rely on friction to provide forward traction, driving the board through the cutting zone.

[0005] However, vertical pressure rollers can only provide clamping force perpendicular to the table surface, and the direction of this clamping force is perpendicular to the direction of the material ejection force that needs to be overcome, thus failing to provide direct and effective resistance. Furthermore, the anti-backflow capability of conventional feed rollers relies entirely on the static friction between the roller surface and the wood board. When encountering knots, excessively thick areas, or areas with sudden density changes during cutting, the cutting resistance increases sharply, easily causing slippage between the feed roller and the wood board surface, making reliable anti-backflow impossible and hindering practical application. Therefore, there is an urgent need for a double-sided planer specifically designed to solve these problems of oblique jump and material ejection. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides a woodworking double-sided planer.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A woodworking double-sided planer includes a lower body, the top of which is connected to an upper body via a lifting column assembly. Support frames are mounted inside both the upper and lower bodies via sliding components. A lower cutter shaft body and an upper cutter shaft body are rotatably mounted on the two support frames, facing each other. A first drive assembly acting on the cutter shaft body is provided inside both the lower and upper bodies. A plurality of lower pressure rollers are rotatably mounted inside the lower body, and a plurality of upper pressure rollers are rotatably mounted inside the upper body, with the number of lower and upper pressure rollers being equal and corresponding one-to-one. A conveyor bed is mounted on the lower body, and a plurality of feed rollers are rotatably mounted inside the conveyor bed. The upper body is equipped with a cleaning component that cooperates with the feed rollers, and also has rotatably mounted limiting rollers and limiting components acting on the limiting rollers.

[0008] Furthermore, the sliding assembly includes slide rails, and several linear slide rails are fixedly installed on the upper body. The same slider is slidably arranged within the several slide rails. The outer surface of the slider is fixedly connected to the support frame and also integrally fixedly provided with a rack. A third motor is fixedly installed on the upper body, and a gear is fixedly provided on the output shaft of the third motor. The gear meshes with the rack for transmission.

[0009] Furthermore, the gear and rack are helical gears and helical racks.

[0010] Furthermore, the first drive assembly includes a first motor, which is fixedly mounted on the upper body, and a first pulley is fixedly provided on the output shaft of the first motor; a second pulley is fixedly sleeved on the outer surface of the upper cutter shaft body, and belts are sleeved on the outer surfaces of the first pulley and the second pulley.

[0011] Furthermore, the cleaning assembly includes a cleaning roller, which is rotatably mounted in the upper body and also fixedly mounted with a protective cover, which is located above the cleaning roller.

[0012] Furthermore, the upper body is provided with a second drive assembly that acts on the cleaning roller.

[0013] Furthermore, the second drive assembly includes a second motor, which is fixedly mounted on the upper body, and a third pulley is fixedly mounted on the output shaft of the second motor; a fourth pulley is fixedly sleeved on the outer surface of the cleaning roller, and a conveyor belt is driven by the outer surfaces of the third pulley and the fourth pulley.

[0014] Furthermore, the limiting component includes a ratchet, and the ratchet is coaxially fixed on the outer surface of the inner rotating shaft of the limiting roller through several connecting plates; an inner pawl and an outer pawl are rotatably provided on the upper body, and both the inner pawl and the outer pawl are engaged with the ratchet drive; a torsion spring is provided at the rotatable connection between the inner pawl and the outer pawl and the upper body.

[0015] This application has the following beneficial effects: 1. This application uses a lifting column assembly to drive the upper pressure roller and the limiting roller to rise and fall synchronously, enabling them to be stably pressed against the surface of the wood board, effectively suppressing the tendency of the wood board to warp due to cutting force. When the cutting process encounters sudden working conditions such as knots that cause a sharp increase in the material retraction force, the limiting component on the limiting roller can reliably lock it, fundamentally preventing the wood board from rolling back. This achieves a stable and reliable anti-rollback function, significantly improving the equipment's adaptability to working conditions and its practical application value.

[0016] 2. This application uses a lifting column assembly to drive the pressure roller and the limiting roller to rise and fall synchronously, thereby achieving synchronous action of pressing and preventing backflow. This effectively suppresses the jumping and backflow of the wooden board, ensures the uniformity of the planing thickness and the surface processing quality, eliminates the risk of equipment jamming or workpiece splashing caused by backflow, protects the safety of operators, and has better practical effect.

[0017] 3. This application integrates a high-precision linear guide rail into the machine body, allowing the operator to pull out the entire tool shaft module along the axial direction without large-scale disassembly of the machine tool, thereby enabling rapid tool replacement, sharpening, or maintenance. It can also maintain extremely high repeatability after resetting, greatly improving the maintainability and overall utilization of the equipment, and further enhancing the practical effect of this application.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1-8 As shown, the technical solution adopted by this utility model is as follows: A woodworking double-sided planer includes a lower body 1, the top of the lower body 1 is connected to an upper body 2 through a lifting column assembly 5, and support frames 28 are installed inside both the upper body 2 and the lower body 1 through sliding components; a lower cutter shaft body 11 and an upper cutter shaft body 10 are rotatably arranged on the two support frames 28, the lower cutter shaft body 11 and the upper cutter shaft body 10 are arranged facing each other, and a first drive assembly acting on the cutter shaft body is provided inside both the lower body 1 and the upper body 2.

[0022] The lower body 1 has several lower pressure rollers 14 rotatably arranged inside, and the upper body 2 has several upper pressure rollers 13 rotatably arranged inside. The number of lower pressure rollers 14 and upper pressure rollers 13 are equal and correspond one-to-one.

[0023] The lower body 1 is equipped with a conveyor bed 3, and several feed rollers 4 are rotatably arranged inside the conveyor bed 3; the upper body 2 is equipped with a cleaning component that cooperates with the feed rollers 4, and a limiting roller 15 and a limiting component acting on the limiting roller 15 are rotatably arranged.

[0024] (It should be noted that the lifting column assembly 5, feed roller 4, and conveyor bed 3 in this application are all conventional prior art, and will not be described in detail here. The lifting column assembly 5 is used to drive the entire upper body 2 to move vertically, thus making it suitable for wooden boards of different sizes. The several feed rollers 4 in the conveyor bed 3 are used to convey and pull the wooden boards, and the conveyor bed 3 has a built-in drive source acting on the feed rollers 4. At the same time, the lower body 1 has a drive source acting on the lower pressure roller 14.) Specifically, such as Figures 6-8 As shown, the sliding assembly includes a slide rail 23. Several linear slide rails 23 are fixedly installed on the upper body 2. The same slider 25 is slidably set in the several slide rails 23. The outer surface of the slider 25 is fixedly connected to the support frame 28 and also integrally fixedly set with a rack 27. A third motor 24 is fixedly mounted on the upper body 2. A gear 26 is fixedly mounted on the output shaft of the third motor 24, and the gear 26 meshes with a rack 27 for transmission. (Note: The structures inside the sliding components of the upper and lower bodies are the same. This application only describes the sliding components inside the upper body 2 in detail.) This application integrates a high-precision linear guide rail into the machine body, allowing the operator to pull out the entire tool shaft module along the axial direction without large-scale disassembly of the machine tool, thereby enabling rapid tool replacement, sharpening, or maintenance. It can also maintain extremely high repeatability after reset, greatly improving the maintainability and overall utilization of the equipment, and further enhancing the practical effect of this application.

[0025] More specifically, this application uses helical gears and helical racks, which provide smooth transmission and lower noise.

[0026] Specifically, such as Figures 1-2 As shown, the first drive assembly includes a first motor 6, which is fixedly mounted on the upper body 2. A first pulley 7 is fixedly mounted on the output shaft of the first motor 6. A second pulley 8 is fixedly sleeved on the outer surface of the upper cutter shaft body 10, and a belt 9 is sleeved on the outer surfaces of the first pulley 7 and the second pulley 8. (Note: The structures within the first drive assembly in the upper and lower bodies are the same; this application only describes the first drive assembly within the upper body 2 in detail.) Specifically, the cleaning assembly includes a cleaning roller 16. The cleaning roller 16 is rotatably mounted inside the upper body 2, and a protective cover 12 is fixedly mounted thereon. The protective cover 12 is located above the cleaning roller 16.

[0027] More specifically, the upper body 2 is provided with a second drive assembly that acts on the cleaning roller 16.

[0028] like Figure 4 As shown, the second drive assembly includes a second motor 17, which is fixedly mounted on the upper body 2. The output shaft of the second motor 17 is fixedly provided with a third pulley 18. A fourth pulley 19 is fixedly sleeved on the outer surface of the cleaning roller 16. A conveyor belt (not shown in the figure) is connected to the outer surfaces of the third pulley 18 and the fourth pulley 19.

[0029] Specifically, such as Figure 5As shown, the limiting component includes a ratchet 20. The ratchet 20 is coaxially fixed on the outer surface of the built-in rotating shaft of the limiting roller 15 through several connecting plates. An inner pawl 21 and an outer pawl 22 are rotatably arranged on the upper body 2. Both the inner pawl 21 and the outer pawl 22 are in transmission cooperation with the ratchet 20.

[0030] More specifically, torsion springs (not shown in the figure) are provided at the rotational connection points between the inner pawl 21 and the outer pawl 22 and the upper body 2.

[0031] Working principle: During use, the wooden planks are conveyed from the left side (reference) via an external conveying device (existing technology). Figure 1 The feed rollers (in the direction of the feed) are fed into the equipment and provided with the main traction force by the feed rollers 4. (It should be noted that the left side of the equipment is also equipped with feed rollers 4 and cleaning components, which are not shown in the attached drawings of the instruction manual.) At the same time, the lifting column assembly 5 is activated, and the height of the upper machine body 2 is adjusted by the lifting column assembly 5 so that the upper pressure roller 13 and the limiting roller 15 in the upper machine body 2 descend synchronously, and together with the lower pressure roller 14 in the lower machine body 1, they form a stable clamping of the wooden board. This linkage ensures the synchronicity of the pressing and anti-retreat actions, creating the initial conditions for stable processing.

[0032] During this process, the first motor 6 is started, and the output shaft of the first motor 6 drives the first pulley 7 to rotate. The first pulley 7 drives the second pulley 8 to rotate via the belt 9, causing the upper cutter shaft body 10 and the lower cutter shaft body 11 to rotate in opposite directions at high speed to plan the upper and lower surfaces of the wooden board. At the same time, the upper pressure roller 13 and the lower pressure roller 14 continuously provide clamping force in front of and behind the cutter shaft to suppress processing vibration and ensure uniform thickness and a smooth surface.

[0033] During this process, the second motor 17 is started, and the output shaft of the second motor 17 drives the third pulley 18 to rotate. The third pulley 18 drives the fourth pulley 19 to rotate via the conveyor belt, causing the cleaning roller 16 to rotate at high speed, thereby sweeping away the wood chips on the wooden board in time. The removed wood chips are efficiently collected by the external dust collection system (existing technology) under the guidance of the protective cover 12, keeping the processing surface clean and maintaining the cleanliness of the equipment.

[0034] Furthermore, during the board feeding process, if the cutting resistance is normal, the limiting roller 15 can rotate freely as the board moves forward. When the cutting process encounters sudden changes such as knots or reverse grain, causing a sharp increase in the material retraction force, the reverse movement tendency of the board will trigger the ratchet 20, which is coaxially fixed with the limiting roller 15. This causes the inner pawl 21 and the outer pawl 22 to engage with the tooth groove of the ratchet 20, thereby locking the limiting roller 15 in one direction to prevent the board from retracting, thus achieving a stable and reliable anti-retraction function.

[0035] When it is necessary to replace or resharpen the tool, start the third motor 24. The output shaft of the third motor 24 drives the gear 26 to rotate. The gear 26 drives the slider 25, the support frame 28 and the entire tool shaft module (including the upper tool shaft body 10 or the lower tool shaft body 11) to be smoothly pulled out of the machine body along the high-precision linear slide rail 23 through the rack 27.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
