Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wood processing equipment technology, specifically to a wood side contouring machine. Background Technology

[0002] When placing wine bottles or other cylindrical objects at an angle, a wooden board with angled semi-elliptical notches at both ends is typically needed for support. In some cases, an additional identical board may be placed on top of the object for further fixation. During the actual transport and placement of wine bottles, a wooden board with two or more angled semi-elliptical notches is required. To meet usage requirements, the spacing between the two semi-elliptical notches must be identical during manufacturing. Ordinary wood processing equipment includes wire cutting and saw blade cutting devices, neither of which can process elliptical notches with beveled edges. In actual processing, high-precision equipment such as CNC milling machines or engraving machines is required. For manufacturers processing only a single product, such equipment is not only expensive to purchase but also inefficient. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a wood board side profile forming machine, which solves the technical problems of high equipment procurement cost and low processing efficiency in the prior art for processing irregular grooves on the side of wood boards.

[0004] According to one aspect, at least one embodiment of the present invention provides a wood panel side profile forming machine, comprising:

[0005] Frame;

[0006] A plurality of cutting blades are arranged linearly at intervals on the frame.

[0007] A sliding frame is slidably mounted on the frame body. The top of the sliding frame is used to place the wood to be cut. The sliding frame can slide close to the cutting blade so that the cutting blade can cut the side of the wood to be cut on the sliding frame. The top of the sliding frame has a first positioning block and a second positioning block, which are respectively used to abut against the two sides adjacent to the wood.

[0008] A pressure plate, which is lifted and lowered on the sliding frame, can be lowered to press against the top of the wood.

[0009] For example, in at least one embodiment of the present invention, a wood panel side contouring machine further includes:

[0010] A linear drive device is mounted on the frame, and the linear drive device is used to drive the sliding frame to slide closer to or away from the cutting blade;

[0011] A positioning plate is installed on the frame.

[0012] A connecting block is disposed on the sliding frame, and the connecting block has a threaded hole;

[0013] The positioning bolt is threadedly connected to the threaded hole on the connecting block. The positioning bolt can slide along with the sliding frame and abut against the positioning plate to prevent the sliding frame from continuing to approach the cutting blade.

[0014] For example, in at least one embodiment of the present invention, a wood board side contouring machine further includes a dust collection assembly, which includes:

[0015] A dust collection hood is installed on the frame, covering the side of the cutting blade away from the sliding frame, and the dust collection hood is used to prevent sawdust from splashing.

[0016] A corrugated pipe is connected at one end to the dust collection hood and at the other end to a negative pressure device. The negative pressure device can suck up the wood chips inside the dust collection hood through the corrugated pipe.

[0017] For example, in at least one embodiment of the present invention, a wood board side contouring machine further includes a transmission mechanism. The transmission mechanism connects the linear drive device and the sliding frame, enabling the linear drive device to drive the sliding frame to slide. The transmission mechanism includes:

[0018] A connector is fixedly mounted on the drive end of the linear drive device, and the connector has a longitudinal through hole;

[0019] The transmission rod is slidably disposed at one end within the through hole;

[0020] A transmission ring is disposed on the sliding frame. The transmission ring is configured such that after the other end of the transmission rod enters the transmission ring, the linear drive device can push against the interior of the transmission ring through the transmission rod, so that the linear drive device drives the sliding frame to slide.

[0021] For example, in a wood board side contouring machine provided in at least one embodiment of the present invention, the transmission ring has a groove, the connecting block is slidably disposed on the sliding frame, a top block is fixedly connected to the top of the connecting block, the top block is located in the groove, the transmission rod is located on the sliding path of the top block, the end of the top block near the transmission rod has a guide slope, the connecting block is configured such that after the positioning bolt abuts against the positioning plate, the connecting block slides relative to the sliding frame, and the top block can slide relative to the sliding frame in the groove, so that the top block can push the transmission rod away from the transmission ring under the action of the guide slope.

[0022] For example, in at least one embodiment of the present invention, a wood panel side contouring machine further includes:

[0023] The first elastic element has two ends acting on the connecting block and the sliding frame respectively. The first elastic element can elastically push the connecting block to slide away from the linear drive device, so that the top block leaves the transmission rod and enters the path of the transmission ring under the drive of the connecting block.

[0024] For example, in a wood board side profile shaping machine provided in at least one embodiment of the present invention, the inner diameter of the transmission ring is larger than the outer diameter of the transmission rod, so that after the transmission rod reaches above the inner wall of the transmission ring under the drive of the linear drive device, it can enter the transmission ring under the action of gravity.

[0025] For example, in at least one embodiment of the present invention, a wood board side contouring machine further includes a positioning and pushing mechanism, the positioning and pushing mechanism comprising:

[0026] A rotating component, rotatably mounted on the sliding frame, the rotating component having a radially extending rod;

[0027] A pusher is slidably mounted on the extension rod. The pusher can slide close to the main shaft of the rotating member. Driven by the rotating member, the pusher can approach the first positioning block and the second positioning block and push the wooden board so that the two adjacent sides of the wooden board abut against the first positioning block and the second positioning block respectively.

[0028] For example, in at least one embodiment of the present invention, a wood panel side contouring machine further includes:

[0029] The second elastic element has two ends acting on the rotating member and the pushing member respectively. The second elastic element can elastically push the pushing member to slide away from the main shaft of the rotating member.

[0030] For example, in a wood board side contouring machine provided in at least one embodiment of the present invention, the pushing member is a 1 / 4 arc, the main axis of the pushing member is parallel to but does not coincide with the main axis of the rotating member, the pushing member can push one side of the wood closer to the first positioning block, and further includes:

[0031] A push block is slidably disposed on the push member, and the push block is capable of sliding along the circumference of the push member;

[0032] The third elastic element has two ends that act on the push block and the pusher respectively. The third elastic element is used to elastically push the push block to slide closer to the second positioning block.

[0033] The beneficial effects of the embodiments of the present invention are as follows:

[0034] In this invention, multiple cutting blades are linearly spaced, and the sliding frame drives the wood edge to be cut to contact multiple cutting blades simultaneously through sliding. Multiple irregularly shaped holes with identical spacing can be processed in a single cut, improving processing efficiency compared to traditional methods and reducing equipment costs compared to CNC machine tools. Simultaneously, the precise positioning and fixing effect of the first positioning block, the second positioning block, and the pressure plate significantly improves cutting accuracy, ensuring consistent spacing and shape of irregularly shaped edges on different types of wood, facilitating the combined use of irregularly shaped edges from different types of wood.

[0035] By adjusting the spacing and shape of the cutting blades, as well as the position of the positioning blocks on the sliding frame, this equipment can adapt to the processing needs of irregularly shaped edges of different specifications and shapes, broadening its application range and improving its versatility and market competitiveness. This wood panel side-shaping machine has a relatively simple structure, eliminating the need to purchase expensive CNC milling machines or engraving machines, significantly reducing equipment procurement costs and simultaneously lowering production costs for enterprises, thus improving economic efficiency.

[0036] The pressure plate effectively secures the wood, preventing it from moving or flying out during cutting, thus ensuring operator safety and reducing operational risks. Attached Figure Description

Detailed Implementation

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0053] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0054] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0057] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0058] like Figures 1-13As shown, this invention illustrates a wood panel side-shaping machine according to one embodiment, comprising a frame 100, a cutting blade 200, a sliding frame 300, and a pressure plate 500. The frame 100 provides a stable mounting base for components such as the cutting blade 200 and the sliding frame 300. During the cutting process, the frame 100 effectively disperses and bears the reaction force generated when the cutting blade 200 cuts the wood 400, ensuring the stability of the entire device during operation, preventing component displacement or damage due to uneven force, and ensuring cutting accuracy. The cutting blade 200 is an irregularly shaped rotating cutter that cuts the side of the wood 400 using its outer blade shape. The shape of the cutting blade 200 is determined according to the shape to be cut from the wood 400. Several cutting blades 200 can be set as needed, each driven by a motor. Adjusting the distance between the cutting blades 200 according to actual needs can accommodate multiple irregularly shaped cuts with consistent spacing on multiple pieces of wood 400. Taking the processing of the semi-elliptical projection misaligned irregular grooves at the upper and lower ends of the wood 400 as an example, the cutting blade 200 used has several circumferentially distributed cutting edges. The cutting edges face the tangential direction of the cutting blade 200. The wood 400 is cut by the rotating cutting edges of the cutting blade 200. Along the main axis of the cutting blade 200, the cutting edges gradually move away from the main axis of the cutting blade 200, so that the upper and lower two elliptical grooves with misaligned projections can be achieved by one cutting blade 200.

[0059] The sliding frame 300 is slidably mounted on the frame 100 via a linear guide rail pair. The guide rail is fixed to the frame 100, and a slider is installed at the bottom of the sliding frame 300 to ensure that the sliding frame 300 can slide smoothly in the direction of approaching or moving away from the cutting blade 200. A first positioning block 310 and a second positioning block 320 are provided on the top of the sliding frame 300. The first positioning block 310 and the second positioning block 320 are respectively vertically positioned on adjacent sides of the top of the sliding frame 300, abutting against the adjacent sides of the wood 400, for positioning the wood 400 and ensuring the positional accuracy of the wood 400 during the cutting process. The sliding frame 300 is also equipped with a lifting mechanism to control the lifting of the pressure plate 500. The lifting mechanism can be a screw and nut mechanism or a hydraulic lifting mechanism.

[0060] The pressure plate 500 is connected to the sliding frame 300 via a lifting mechanism. When the lifting mechanism drives the pressure plate 500 to descend, the pressure plate 500 can firmly press against the top of the wood 400. As the pressure plate 500 descends under the action of the lifting mechanism and firmly presses against the top of the wood 400, it effectively fixes the wood 400 when the cutting blade 200 cuts the side of the wood 400, preventing the wood 400 from moving or shaking due to the cutting force, ensuring cutting accuracy, improving processing quality, and simultaneously ensuring the safety of the operator.

[0061] Working Principle: The wood 400 to be cut is placed on top of the sliding frame 300, with adjacent sides of the wood 400 abutting against the first positioning block 310 and the second positioning block 320 respectively, thus positioning the wood 400. The lifting mechanism is activated, driving the pressure plate 500 to descend and press firmly against the top of the wood 400, securing the wood 400 firmly to the sliding frame 300. The motor is started, driving the cutting blade 200 to rotate at high speed. By controlling the sliding frame 300 to slide along the linear guide towards the cutting blade 200, the sides of the wood 400 gradually approach the cutting blade 200. The cutting blade 200 cuts the sides of the wood 400. Due to the linear spacing and precise spacing of multiple cutting blades 200, multiple irregularly shaped edges with the same spacing can be processed on the sides of the wood 400 in a single cutting stroke. During the cutting process, the operator can adjust the cutting efficiency and quality by controlling the sliding speed of the sliding frame 300, and can also adjust the cutting depth by controlling the sliding distance of the sliding frame 300. After cutting is completed, the motor is stopped, causing the cutting blade 200 to stop rotating. Then, control the sliding frame 300 to slide in the opposite direction and return to the initial position. Start the lifting mechanism to raise the pressure plate 500 and release the pressure on the wood 400. Remove the cut wood 400 from the sliding frame 300 to complete the entire processing.

[0062] Multiple cutting blades are linearly spaced 200, allowing for the production of multiple irregularly shaped holes with identical spacing in a single cut. This improves processing efficiency compared to traditional methods and reduces equipment costs compared to CNC machine tools. Simultaneously, the precise positioning and fixing effect of the first positioning block 310, the second positioning block 320, and the pressure plate 500 significantly enhances cutting accuracy, ensuring consistent spacing and shape of irregularly shaped edges on different types of wood 400, facilitating the coordinated use of irregularly shaped edges from different types of wood 400.

[0063] By adjusting the spacing and shape of the cutting blades 200 and the position of the positioning blocks on the sliding frame 300, this equipment can adapt to the processing needs of irregularly shaped edges of different specifications and shapes, broadening the application range of the equipment and improving its versatility and market competitiveness. This wood panel side-shaping machine has a relatively simple structure, eliminating the need to purchase expensive CNC milling machines or engraving machines, significantly reducing equipment procurement costs and simultaneously lowering production costs for enterprises, thus improving economic efficiency.

[0064] The pressure plate 500 effectively secures the wood 400, preventing it from moving or flying out during cutting, thus ensuring operator safety and reducing operational risks.

[0065] In some examples, a linear drive 610, a positioning block, a connecting block 630, and a positioning bolt 640 are also included. The linear drive 610 is a ball screw drive mechanism, an electric cylinder, or a pneumatic cylinder to ensure the precise and smooth movement of the sliding frame 300. The linear drive 610 provides power to the sliding frame 300, enabling it to slide closer to or further away from the cutting blade 200 at a set speed and distance. During the cutting of the wood 400, by controlling the movement of the sliding frame 300, the cutting position and depth of the wood 400 are controlled, thereby ensuring that the dimensions of the cut irregular holes are accurate and the spacing is consistent, improving processing accuracy and efficiency.

[0066] The positioning plate 620 is rectangular in shape and is fixed to the frame 100 by welding or bolts. The connecting block 630 is a block structure and is fixed to the sliding frame 300 by welding or bolts. The connecting block 630 has a threaded hole 631, which connects the positioning bolt 640 to the sliding frame 300, allowing the positioning bolt 640 to move synchronously with the sliding frame 300. The positioning bolt 640 cooperates with the positioning plate 620 to limit the movement of the sliding frame 300 as it approaches the cutting blade 200. By adjusting the screw depth of the positioning bolt 640 in the threaded hole 631 of the connecting block 630, the final position of the sliding frame 300 can be finely adjusted, thereby achieving precise control over the cutting depth and the position of irregular holes to meet different processing requirements.

[0067] The working principle is as follows: based on the actual dimensions of the wood 400 to be processed, the positioning bolt 640 is rotated, causing one end of the positioning bolt 640 near the positioning plate 620 to extend beyond the threaded hole 631 by different lengths. The specific length can be confirmed by the scale markings on the sliding frame 300. As the linear drive device 610 drives the sliding frame 300 closer to the cutting blade 200, one end of the positioning bolt 640 also gradually approaches the positioning plate 620. After reaching the set distance, one end of the positioning bolt 640 abuts against the positioning plate 620, preventing the linear drive device 610 from overcutting due to mechanical failure or other reasons.

[0068] In some examples, a dust collection assembly is also included, comprising a dust hood 710 and a bellows 720. The dust hood 710 is shaped according to the contours and positions of all the cutting blades 200, and is semi-enclosed to effectively cover the side of all the cutting blades 200 away from the sliding frame 300. The opening size of the dust hood 710 is slightly larger than the length of the linearly arranged cutting blades 200, ensuring that the cutting blades 200 do not interfere with the dust hood 710 during rotation, while maximizing the prevention of sawdust splashing.

[0069] The main function of the dust collection hood 710 is to prevent wood chips generated during the cutting process from splashing outwards when the cutting blade 200 is working, confining the wood chips within the dust collection hood 710's internal space, thus creating conditions for subsequent collection and cleaning. It effectively improves the working environment, reduces the health hazards of wood chips to operators, and also reduces the contamination of other equipment components by wood chips, helping to extend the equipment's service life.

[0070] The corrugated pipe 720 is made of flexible, wear-resistant and corrosion-resistant material, which makes it easy to adjust to different installation positions. The two ends of the corrugated pipe 720 are respectively provided with connection interfaces. One end is tightly connected to the dust discharge port of the dust collection hood 710, and the other end is connected to the suction port of the negative pressure device. The connection method can be clamp or threaded connection to ensure a firm connection and good sealing to prevent sawdust leakage.

[0071] The corrugated pipe 720 serves as a channel connecting the dust collection hood 710 and the negative pressure device, responsible for conveying the wood chips collected inside the dust collection hood 710 to the negative pressure device. Its flexible design allows it to extend and retract flexibly during equipment operation, following the movement of the cutting blade 200 or other components, without affecting the normal operation of the equipment. At the same time, it effectively guides the wood chips from the dust collection hood 710 to the negative pressure device, achieving efficient collection of wood chips.

[0072] Negative pressure systems typically employ industrial vacuum cleaners or specialized dust collection fans, which are usually equipped with auxiliary devices such as cyclone separators or bag filters to separate and collect sawdust. The negative pressure system is equipped with a power supply or power interface for connection to an external power source or system to ensure its normal operation.

[0073] In some examples, a transmission mechanism is used to connect the linear drive unit 610 and the sliding frame 300 so that the linear drive unit 610 can drive the sliding frame 300 to slide. The transmission mechanism includes a connector 810, a transmission rod 820 and a fixing ring. The connector 810 is generally block-shaped and is fixed to the drive end of the linear drive unit 610 by welding or bolting. The connector 810 has a longitudinal through hole 811 at its center. The diameter of the through hole 811 is adapted to the outer diameter of the transmission rod 820 so that the transmission rod 820 can move up and down within the through hole 811.

[0074] The connector 810, serving as the component connecting the linear drive unit 610 and the transmission rod 820, transmits the driving force generated by the linear drive unit 610 to the transmission rod 820. Its robust connection to the drive end of the linear drive unit 610 ensures the stability of power transmission, while the through hole 811, in conjunction with the transmission rod 820, provides a sliding guide for the transmission rod 820, enabling it to move linearly along the driving direction perpendicular to the linear drive unit 610.

[0075] The transmission rod 820 acts as a bridge between the connector 810 and the transmission ring 830, transmitting the driving force from the linear drive device 610 to the sliding frame 300 via the connector 810. Guided by the connector 810, the transmission rod 820 moves linearly along the driving direction perpendicular to the linear drive device 610. When the transmission rod 820 descends, its lower end interacts with the transmission ring 830, pushing the transmission ring 830 and thus causing the sliding frame 300 to slide on the frame 100, achieving precise driving of the sliding frame 300 by the linear drive device 610. When the transmission rod 820 rises and its other end moves away from the transmission ring 830, the transmission connection between the transmission rod 820 and the transmission ring 830 is broken, and the sliding frame 300 can no longer be driven to slide by the linear drive device 610.

[0076] The transmission ring 830 has a ring-shaped structure, with its inner diameter slightly larger than the outer diameter of the other end of the transmission rod 820, ensuring that the transmission rod 820 can smoothly enter. The transmission ring 830 is firmly fixed to the sliding frame 300 by welding or bolting, and its installation position corresponds to the position of the connecting piece 810 and the transmission rod 820. The bottom of the transmission ring 830 has a sealing plate to support the bottom of the transmission rod 820, preventing the transmission rod 820 from passing through the transmission ring 830. As the connection point between the transmission mechanism and the sliding frame 300, the transmission ring 830 receives the driving force transmitted by the transmission rod 820 and transmits it to the sliding frame 300, thereby realizing the driving of the sliding frame 300 by the linear drive device 610.

[0077] The working principle is as follows: the sliding bracket 300 positions the inner ring of the transmission ring 830 directly below the through hole 811 of the connector 810. The transmission rod 820 is inserted from above the through hole 811 and enters the inner ring of the transmission ring 830, allowing the outer ring of the transmission rod 820 to push against the inner ring of the transmission ring 830. This enables the linear drive device 610 to drive the sliding bracket 300 to slide.

[0078] The modular design of the transmission mechanism makes it easy to disassemble and replace the components. When a component is worn or damaged, the connector 810, transmission rod 820, or transmission ring 830 can be replaced individually, reducing maintenance costs and repair difficulty.

[0079] In some examples, the connecting block 630 is slidably mounted on the sliding frame 300. The transmission ring 830 has a groove 831 that extends through the transmission ring 830 and to the side of the sliding frame 300 along the driving direction of the linear drive device 610. The connecting block 630 is slidably mounted on the sliding frame 300. A top block 632 is fixedly connected to the top of the connecting block 630. The top block 632 is located within the groove 831 and can slide smoothly within the groove 831 without excessive wobbling. The transmission rod 820 is located on the sliding path of the top block 632, and the end of the top block 632 near the transmission rod 820 has a guide slope 6321.

[0080] The sliding connection of the connecting block 630 on the sliding frame 300 allows the connecting block 630 to slide relative to the sliding frame 300 towards the linear drive device 610 when the positioning bolt 640 abuts against the positioning plate 620. The top block 632, driven by the connecting block 630, slides within the groove 831 of the transmission ring 830. During sliding, the top block 632 acts on the transmission rod 820 through the guide inclined surface 6321, causing the transmission rod 820 to rise and move away from the transmission ring 830, thus preventing the transmission rod 820 from further moving the transmission ring 830. This avoids excessive cutting of the wood 400 due to excessive movement of the linear drive device 610, and also prevents damage to components caused by the interaction between the linear drive device 610, the positioning plate 620, and the positioning bolt 640.

[0081] It should be noted that after the transmission rod 820 rises away from the inner ring of the transmission ring 830, the bottom of the transmission rod 820 always abuts against the bottom of the transmission ring 830, ensuring that the transmission rod 820 can fall back onto the inner ring of the transmission ring 830 when sliding in the opposite direction.

[0082] In some examples, a first elastic element 840 is also included. The first elastic element 840 is a helical spring. The two ends of the first elastic element 840 are reliably fixed to the connecting block 630 and the sliding frame 300 by welding, respectively, to ensure that it will not fall off during operation.

[0083] The first elastic element 840 plays a crucial role in elastic reset between the connecting block 630 and the sliding frame 300. When the positioning bolt 640 abuts against the positioning plate 620, and the connecting block 630 slides relative to the sliding frame 300, causing the top block 632 to push the transmission rod 820 away from the transmission ring 830, the first elastic element 840 stores elastic potential energy. After the transmission rod 820 leaves the transmission ring 830, the cutting is completed. Under the action of the elastic potential energy of the first elastic element 840, the sliding frame 300 slides towards the linear drive device 610, causing the top block 632 to leave the entry position of the transmission rod 820. The driving end of the linear drive device 610 moves in the opposite direction, driving the transmission rod 820 to reach above the transmission ring 830, allowing the transmission rod 820 to enter the interior of the transmission ring 830 under the action of gravity, thereby enabling the sliding frame 300 to slide away from the cutting blade 200 through the transmission ring 830.

[0084] The first elastic element 840 enables the automatic reset of the connecting block 630 and the top block 632, eliminating the need for manual operation, thus improving the automation level of the equipment and reducing the workload of operators. In continuous cutting operations, the connecting block 630 and the top block 632 can quickly reset after each cut, saving operation time.

[0085] The working principle is as follows: by rotating the positioning bolt 640, the end of the positioning bolt 640 close to the positioning plate 620 is kept at a certain distance from the positioning plate 620. The top block 632 moves to fix the position of the transmission rod 820 away from the inner ring of the transmission ring 830. The actual distance processed by the sliding frame 300 is the distance between the positioning bolt 640 and the positioning plate 620 plus the distance that the top block 632 slides to push the transmission rod 820 away from the inner ring of the transmission ring 830.

[0086] In some examples, the inner diameter of the transmission ring 830 is larger than the outer diameter of the transmission rod 820, which ensures that the transmission rod 820 can smoothly enter the transmission ring 830 under the action of gravity. This method allows the transmission rod 820 to fall naturally into the transmission ring 830 under the action of gravity after reaching the inner wall of the transmission ring 830 driven by the linear drive device 610, simplifying the connection process between the transmission rod 820 and the transmission ring 830.

[0087] In some examples, a positioning and pushing mechanism is also included, which includes a rotating component 910 and a pushing component 920. The rotating component 910 is rotatably mounted on the sliding frame 300 via a bearing and is driven to rotate by an independent motor. The rotating component 910 is generally disc-shaped, and its central axis is perpendicular to the surface of the sliding frame 300 to ensure that its radial extension rod 911 can function effectively in the horizontal direction.

[0088] The pusher 920 is provided with a groove 831 or a through hole 811 that matches the extension rod 911, allowing it to slide freely on the extension rod 911. Driven by the rotating member 910, the pusher 920 slides along the extension rod 911 and approaches the first positioning block 310 and the second positioning block 320. When the pusher 920 contacts the wooden board, as the rotating member 910 continues to rotate, the pusher 920 pushes the wooden board, causing the two adjacent sides of the wooden board to abut tightly against the first positioning block 310 and the second positioning block 320, thereby completing the positioning operation of the wooden board.

[0089] In some examples, a second elastic element 930 is also included. The second elastic element 930 is a helical spring, and its two ends are reliably connected to the rotating element 910 and the pushing element 920 respectively by welding or hooking, ensuring it will not detach during operation. The second elastic element 930 plays a crucial role in elastic reset and buffering between the rotating element 910 and the pushing element 920. When the pushing element 920 approaches the wood 400 under the influence of the rotating element 910, its length can be adjusted by pressing the second elastic element 930 according to the size of the wood 400. This allows it to accommodate different sizes of wood 400 for positioning, and the force of the second elastic element 930 can also provide the force for the pushing element 920 to push the wood 400 closer to the first positioning block 310.

[0090] In some examples, the pusher 920 is a quarter-circle arc, and there is an eccentricity between the pusher 920 and the rotating member 910. This allows the pusher 920 to rotate, and on the one hand, after one side of the wood 400 abuts against the first positioning block 310, a reaction force is applied to the pusher 920, causing the pusher 920 to compress the spring, thus allowing the rotating member 910 to continue rotating. On the other hand, the eccentric arrangement of the pusher 920 creates a transition zone when the rotating member 910 drives the pusher 920 to rotate closer to the wood 400. In this zone, the point where the pusher 920 first contacts the wood 400 is furthest from the first positioning block 310. As the rotating member 910 rotates, the distance between the point where the pusher 920 contacts the wood 400 and the first positioning block 310 gradually decreases, allowing the pusher 920 to push wood 400 of different sizes.

[0091] It also includes a push block 940 and a third elastic element 950. A slide rail is provided on the arc surface of the push member 920, extending circumferentially along the push member 920 for sliding the push block 940. Under the action of the third elastic element 950, the push block 940 can slide circumferentially along the push member 920. When the push member 920 pushes one side of the wood 400 closer to the first positioning block 310, the push block 940 simultaneously pushes the other side of the wood 400 closer to the second positioning block 320, thereby achieving simultaneous contact between the two adjacent sides of the wood 400 and the first positioning block 310 and the second positioning block 320, completing the precise positioning of the wood 400.

[0092] The third elastic element 950 acts on the push block 940 and the jacking element 920 at its two ends respectively. The third elastic element 950 is used to elastically push the push block 940 to slide closer to the second positioning block 320. When the rotating element 910 rotates and drives the push block 940 to contact the other side of the wooden board through the jacking element 920, the third elastic element 950 is compressed. When the resistance of the push block 940 pushing the wood 400 is less than the elastic force of the third elastic element 950, the push block 940 pushes the wood 400 closer to the second positioning block 320 until the wood 400 is tightly against the second positioning block 320. The rotating element 910 continues to rotate, causing the push block 940 to continue to compress the third elastic element 950. When the rotating element 910 reverses and drives the jacking element 920 away from the wood 400, the third elastic element 950 drives the push block 940 to reset, making it convenient for the next use.
