Technical Field
[0001] This invention belongs to the field of bamboo processing technology, specifically relating to a device for straightening and fixing the teeth of bamboo strips. Background Technology
[0002] In the early stages of manufacturing bamboo laminated timber or bamboo strip splicing, the rough-processed bamboo strips need to be cut to a fixed length and have teeth cut on both ends before splicing to form a toothed structure that can be used for tenon and mortise bonding. Therefore, the flatness of the bamboo strip end face, the consistency of the tooth groove shape, and the accuracy of the position of the tooth grooves at both ends have a direct impact on the straightness and bonding strength after splicing.
[0003] Currently, this process is still mainly carried out manually with the assistance of simple machinery. During the operation, workers manually align and support the ends of bundled bamboo strips before pushing them into the cutting area of the toothed cutter to complete the processing.
[0004] However, during the high-speed cutting process, due to the lack of effective vertical and lateral constraints on the ends of the bamboo strips, the bamboo strip bundles are prone to vertical jumping or lateral slippage, which can lead to insufficient tenon precision and uneven cut surfaces, directly affecting the subsequent splicing quality. At the same time, manual operation is inefficient, labor-intensive, and difficult to guarantee the consistency of finished products, making it unsuitable for the requirements of automated continuous production. Summary of the Invention
[0005] The purpose of this invention is to provide a bamboo strip straightening and fixing tooth opening device, which solves the technical problems of insufficient constraint on the bamboo strip ends, poor product consistency, low processing efficiency and high labor intensity in the prior art.
[0006] This invention discloses a bamboo strip straightening and fixing tooth opening device, comprising: The base extends along a first horizontal direction in its length direction; Two toothed assemblies are mounted on the base and spaced apart from each other along a first horizontal direction; each toothed assembly includes: Support base, mounted on the base; A support beam is mounted on the support base and extends along a second horizontal direction, which is perpendicular to the first horizontal direction. The support platform is slidably mounted on the support beam along the second horizontal direction; A support plate is installed on the top surface of the support platform to support the ends of the bamboo strips; A side baffle is installed on one side of the support plate in the second horizontal direction; A side-pushing mechanism is installed on the support platform and located on the other side of the support plate in the second horizontal direction, for pushing against the side of the bamboo strip end in the second horizontal direction; A pressing mechanism is installed on the top surface of the support platform and located above the support plate, for pressing the ends of the bamboo strips vertically. A cutting mechanism is installed on the top surface of the support base and located on the outside of the support plate along the first horizontal direction, for cutting off the portion of the bamboo strip end that extends beyond the support plate along the first horizontal direction and exceeds a preset length; A tooth-opening mechanism is installed on the top surface of the support base and is located downstream of the cutting mechanism along the second horizontal direction, for tooth-opening processing of the end face of the cut bamboo strip; A connecting frame extends along the first horizontal direction and is fixedly connected at both ends to the support platforms of the two toothed assemblies, for the purpose of enabling the two support platforms to move synchronously. A drive mechanism is installed between the support platform and the support beam included in one of the geared assemblies to drive the support platform to slide back and forth in a second horizontal direction; A pushing mechanism is installed on one of the support bases and is positioned downstream of the tooth-opening mechanism along the second horizontal direction, for pushing out the toothed bamboo strip along the first horizontal direction.
[0007] This application utilizes the synergy of a support plate, side baffles, a side pushing mechanism, and a clamping mechanism to create dual vertical and lateral constraints on the bamboo strip ends before processing. This effectively suppresses vertical jump and lateral slippage of the bamboo strip during cutting, improving end-face flatness and tenoning accuracy. Furthermore, the connecting frame enables synchronous translation of both ends, ensuring precise length setting and tenoning position. The sequential arrangement of the cutting mechanism, tenoning mechanism, and pushing mechanism along the sliding direction of the support platform allows the bamboo strip to continuously complete length trimming, end-face tenoning, and automatic unloading after a single clamping and positioning. This effectively reduces manual labor intensity, waiting and turnaround time, avoids repeated clamping, ensures consistent processing dimensions, and improves production automation and processing efficiency.
[0008] Based on the above technical solution, the solution of this application can be further improved as follows: Preferably, the two ends of the connecting frame are detachably connected to the support platforms of the two toothed assemblies, and the support seat of one toothed assembly is fixedly installed on the base, while the support seat of the other toothed assembly is slidably installed on the base along the first horizontal direction. This solution enables rapid adjustment of the distance between the two toothed assemblies, allowing the device to flexibly adapt to the processing needs of bamboo strips of different lengths. Furthermore, only the connecting frame needs to be disassembled during replacement, significantly shortening downtime for specification switching. While ensuring processing accuracy, it achieves multi-purpose functionality and effectively reduces equipment costs for multi-specification production.
[0009] Preferably, the side-pushing mechanism includes: A support platform is fixedly connected to the end of the bearing platform on the side away from the side baffle in the second horizontal direction, and the top surface of the support platform is flush with the top surface of the support plate. The first cylinder is fixedly installed on the support platform on the side away from the support plate; A horizontal push plate is slidably attached to the top surface of the support platform and fixedly connected to the drive end of the first cylinder. It is used to push the end of the bamboo strip toward the side baffle along the second horizontal direction. This solution ensures that no vertical component force is generated during the pushing process, effectively prevents the bamboo strip from being pushed up, and makes the side of the bamboo strip evenly stressed, providing reliable lateral constraint protection.
[0010] Preferably, the clamping mechanism includes: The clamping frame, L-shaped, is installed on the top surface of the support platform and includes an integrally connected vertical section and a horizontal section. The vertical section is located on the side of the support plate away from the side baffle in the second horizontal direction, and the horizontal section extends from the top of the vertical section to the top of the support plate. Multiple second cylinders are installed at intervals on the top surface of the horizontal section, and the drive end of each second cylinder penetrates vertically downward through the horizontal section; A pressing frame is horizontally arranged between the support plate and the horizontal section, and is fixedly connected to the drive end of each of the second cylinders, for pressing the ends of the bamboo strips in the vertical direction; The horizontal push plate has a clearance groove on the side near the side baffle that is adapted to the vertical section, so that the horizontal push plate does not interfere with the vertical section when it moves along the second horizontal direction. With this solution, the clamping force is applied evenly to the end of the bamboo strip, avoiding local deformation caused by single-point pressure, and the side push and clamping actions can operate independently in the same space without interference, realizing the dual constraint of the bamboo strip in the vertical and lateral directions, effectively suppressing the vertical runout during cutting.
[0011] Preferably, the cutting mechanism includes: A fixing frame is installed on the top surface of the support base; A first motor is mounted on the fixed frame, and its output shaft extends along the first horizontal direction; The first cutting wheel is coaxially mounted on the output shaft of the first motor; The second cutting wheel is coaxially mounted on the output shaft of the first motor; In this design, the second cutting wheel is located on the side of the first cutting wheel near the support plate along the first horizontal direction, and the outer diameter of the second cutting wheel is smaller than that of the first cutting wheel. By adopting this design, the bamboo strip end is first efficiently removed along the sliding direction, and then the end face is finely trimmed, thus forming a graded progressive cutting. This design not only ensures the processing efficiency of fixed-length trimming, but also effectively suppresses the cutting defects of the bamboo end face, providing a flat reference end face for subsequent tooth cutting. At the same time, the structure is compact, reliable, and easy to maintain.
[0012] Preferably, the tooth-opening mechanism includes: A fixing plate is installed on the fixing frame; The drive shaft is vertically and rotatably mounted on the fixed plate; A gear with open teeth is coaxially and fixedly connected to the upper end of the transmission shaft; The second motor is mounted on the fixed plate, and its output shaft is connected to the transmission shaft. This design shares the same mounting reference with the cutting mechanism, resulting in a compact layout and reduced errors. Furthermore, the gear-type cutter completes all tooth groove machining in one pass, achieving high production efficiency and ensuring consistency.
[0013] Preferably, the drive mechanism includes: The third motor is mounted on the support platform; The transmission gear is coaxially mounted on the output shaft of the third motor; A transmission rack extends along the second horizontal direction and is mounted on the support beam, and the transmission rack meshes with the transmission gear. This solution realizes the direct conversion of the motor's rotary motion into the linear reciprocating motion of the support platform. The transmission chain is short and has good rigidity, effectively ensuring the accuracy and stability of the feed displacement.
[0014] Preferably, the pushing mechanism includes: A base is installed on the top surface of the support base; A longitudinal push plate is slidably mounted above the base along the first horizontal direction; An extension frame is installed on the side of the base away from the support plate in the first horizontal direction; A long push rod is installed on the extension frame and extends along the first horizontal direction, with its drive end fixedly connected to the longitudinal push plate. This solution provides sufficient pushing stroke to ensure that the bamboo strip does not interfere with the pushing component when it moves, and realizes the connection between the pushing action and the processing path. It has a compact structure, reliable operation, and effectively completes the automatic lateral feeding of bamboo strips, reducing manual labor and improving the continuous operation capability of the device.
[0015] Preferably, the top surface of the base has a material storage channel extending along the first horizontal direction; An inclined groove is provided on the top surface of the support base. The inclined groove extends downward along the first horizontal direction to the side of the support base and corresponds to the material storage channel. The tooth-opening mechanism is located above the upper opening of the inclined groove, and is used to guide the debris generated by the tooth-opening process to the storage channel through the inclined groove. This solution realizes the non-powered collection of processing waste, effectively avoids the accumulation of debris in the processing area, ensures the cleanliness of the device, and facilitates subsequent unified cleaning, thereby improving the operational reliability and maintenance convenience of the equipment.
[0016] Preferably, the support base and the base are vertically aligned on both sides along the second horizontal direction; the top surface of the support base is also provided with a guide groove, which is located below the cutting mechanism and extends downward from the top surface of the support base to the side of the support base in the second horizontal direction; this solution realizes timely guidance and lateral discharge of cutting waste; effectively prevents the accumulation of cutting debris in the processing area, avoids interference of debris with the sliding parts of the bearing platform, and improves the cleanliness and maintenance convenience of continuous operation of the device.
[0017] Through the above technical solution, the present invention achieves the following beneficial effects: 1. This application, through the synergy of the support plate, side baffle, side pushing mechanism, and clamping mechanism, forms a dual constraint on the bamboo strip end in both vertical and lateral directions before processing. This effectively suppresses the vertical jump and lateral slippage of the bamboo strip during cutting, improves the flatness of the end face and the accuracy of the tenoning. Furthermore, the connecting frame enables synchronous translation of both ends, ensuring the precise length and toothing position of both ends. Moreover, through the sequential arrangement of the cutting mechanism, toothing mechanism, and pushing mechanism along the sliding direction of the support table, the bamboo strip can continuously complete the fixed-length trimming, end face toothing, and automatic unloading after one clamping and positioning. This effectively reduces the intensity of manual labor, reduces waiting and turnaround time, avoids repeated clamping, ensures the consistency of processing dimensions, and improves the level of production automation and processing efficiency. 2. This application separates the two ends of the connecting frame from the two support platforms, then slides the movable side toothed assembly along the first horizontal direction of the base to the target position adapted to the length of the bamboo strip to be processed, and finally replaces the matching connecting frame and detachably connects its two ends to the two support platforms respectively. This realizes the rapid adjustment of the spacing between the two toothed assemblies, enabling the device to flexibly adapt to the processing needs of bamboo strips of different lengths. Moreover, only the connecting frame needs to be disassembled when replacing, which significantly shortens the downtime for specification switching. While ensuring processing accuracy, it achieves multi-purpose use and effectively reduces the equipment cost for multi-specification production. Attached Figure Description

[0020] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.
[0021] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0022] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.
[0023] Example: like Figures 1 to 3 As shown in the embodiment of this application, a bamboo strip straightening and fixing tooth-opening device is disclosed, which can automatically straighten, clamp, cut to a fixed length and open teeth at both ends of bamboo strips, thereby improving the processing quality and production efficiency of the mortise and tenon groove at the end of bamboo strips. Its specific structure includes: a base 1, two tooth-opening assemblies 2, a connecting frame 3, a driving mechanism 4 and a pushing mechanism 5.
[0024] The base 1 is used to support other working parts, and its length extends along the first horizontal direction X.
[0025] Two toothed assemblies 2 are mounted on the base 1 and are spaced apart relative to each other along the first horizontal direction X, for respectively regularizing, fixing, cutting and toothing the left and right ends of the bamboo strip.
[0026] like Figure 3 and Figure 4 As shown, each toothed assembly 2 includes: a support base 21, a support beam 22, a bearing platform 23, a support plate 24, a side baffle 25, a side pushing mechanism 26, a pressing mechanism 27, and a cutting mechanism 28.
[0027] The support base 21 is mounted on the base 1 and is used as a mounting base to support all subsequent components.
[0028] The support beam 22 is mounted on the support base 21 and extends along the second horizontal direction Y, which is perpendicular to the first horizontal direction X, to provide a sliding guide along the width direction of the bamboo strip.
[0029] The support platform 23 is slidably mounted on the support beam 22 along the second horizontal direction Y. It is used as a movable worktable for clamping the end of the bamboo strip. It can move along the second horizontal direction Y so that the end of the bamboo strip passes through the cutting station and the tooth-opening station in sequence. Multiple sliding seats are provided at its bottom, and corresponding slide rails are provided on the top surface of the support beam 22, so as to realize a stable sliding connection between the support platform 23 and the support beam 22.
[0030] The support plate 24 is installed on the top surface of the support platform 23 to support the end of the bamboo strip, provide a support plane for the lower surface of the bamboo strip end, and determine the reference height of the bamboo strip in the vertical direction.
[0031] The side baffle 25 is installed on one side of the support plate 24 in the second horizontal direction Y, and is used as a positioning reference in the width direction of the bamboo strip. After the side of the bamboo strip is attached to the plate, its position in the width direction will be determined.
[0032] The side-pushing mechanism 26 is installed on the support platform 23 and is located on the other side of the support plate 24 in the second horizontal direction Y. It is used to push the side of the bamboo strip end along the second horizontal direction Y, and cooperate with the side baffle 25 to clamp the bamboo strip end, eliminate the gap in the width direction of the bamboo strip, and prevent lateral slippage during processing.
[0033] The clamping mechanism 27 is installed on the top surface of the support platform 23 and is located above the support plate 24. It is used to clamp the end of the bamboo strip in the vertical direction, thereby pressing the bamboo strip onto the support plate 24, thus eliminating vertical gaps and preventing vertical jump during cutting.
[0034] The cutting mechanism 28 is installed on the top surface of the support base 21 and is located on the outside of the support plate 24 along the first horizontal direction X. It is used to cut off the part of the bamboo strip end that extends out of the support plate 24 along the first horizontal direction X and exceeds the preset length, so as to achieve fixed length cutting and ensure that the total length of the bamboo strip is accurate and consistent.
[0035] The tooth-opening mechanism 29 is installed on the top surface of the support base 21 and is located downstream of the cutting mechanism 28 along the second horizontal direction Y. It is used to open the teeth on the end face of the cut bamboo strip to form the tenon teeth of the required shape and realize the tooth opening of the end face.
[0036] The connecting frame 3 extends along the first horizontal direction X, and its two ends are fixedly connected to the support platform 23 of the two toothed assemblies 2, respectively, so as to enable the two support platforms 23 to move synchronously and ensure that the processing actions at both ends are synchronized.
[0037] The drive mechanism 4 is installed between the bearing platform 23 and the support beam 22 included in one of the geared assemblies 2, and is used to drive the bearing platform 23 to reciprocate along the second horizontal direction Y.
[0038] The pushing mechanism 5 is installed on one of the support bases 21 and is located downstream of the tooth-opening mechanism 29 along the second horizontal direction Y. It is used to push out the toothed bamboo strip along the first horizontal direction X so that it is fed onto the subsequent conveying device.
[0039] The workflow of the above technical solution is as follows: Step A: Arranging and fixing the bamboo strips: Along the first horizontal direction X, place both ends of the bundle of bamboo strips flat on the support plates 24 of the two toothed assemblies 2. Then, the side pushing mechanism 26 is activated, moving along the second horizontal direction Y toward the side baffle 25, pushing against the long side of the bamboo strip, clamping the end of the bamboo strip horizontally between the side baffle 25 and the pushing component, eliminating the horizontal movement gap of the bamboo strip and preventing horizontal shaking during cutting. Next, the pressing mechanism 27 is activated, pressing the narrow side of the end of the bamboo strip vertically downward, pressing and fixing the end of the bamboo strip vertically onto the support plate 24, eliminating the vertical jump gap of the bamboo strip. At this point, both ends of the bamboo strip are neatly fixed on the support platform 23.
[0040] Step B: Cut the bamboo strips to a fixed length: The drive mechanism 4 is activated, causing the support platform 23 of the toothed assembly 2 to slide along the support beam 22 in the second horizontal direction Y. Since the connecting frame 3 connects the support platforms 23 of the two toothed assemblies 2 into one unit, the support platform 23 on the other side can also slide synchronously in the second horizontal direction Y. As the support platform 23 moves, the bamboo strip that is clamped and fixed moves along the support platform 23 as a whole in the second horizontal direction Y. Thus, the two ends of the bamboo strip first pass through the cutting mechanism 28. When the part of the bamboo strip that extends out of the support plate 24 in the first horizontal direction X and exceeds the preset length enters the cutting area, this part is cut off, realizing the simultaneous fixed-length cutting of both ends of the bamboo strip.
[0041] Step C: Toothing the end face of the bamboo strip: Under the continued drive of the drive mechanism 4, the support platform 23 moves the bamboo strip that has been cut to a fixed length forward along the second horizontal direction Y. The end face of the bamboo strip then enters the working area of the tooth-opening mechanism 29. The tooth-opening cutter in the tooth-opening mechanism 29 is in a rotating working state. When the end face of the bamboo strip passes by, the cutter performs milling processing on the end face, forming a tenon structure of preset shape and depth on the end face of the bamboo strip. At this time, since the bamboo strip is always in the clamping state of the side-pushing mechanism 26 and the clamping mechanism 27 during the processing, the bamboo strip will not slip laterally or jump vertically during the tooth-opening process, thus ensuring the consistency of the tooth groove shape and the flatness of the end face.
[0042] Step D: Cutting bamboo strips: After the toothing process is completed, the support platform 23, driven by the drive mechanism 4, moves the bamboo strip forward along the second horizontal direction Y. When the support platform 23 reaches the preset discharge position, the side push mechanism 26 and the pressing mechanism 27 are released in sequence, releasing the constraint on the end of the bamboo strip. At this time, the push mechanism 5 is started, and its push plate component moves along the first horizontal direction X, pushing against one end of the bundle of bamboo strips, pushing the bamboo strip that has been cut and toothed at both ends out from the support plate 24 along the first horizontal direction X, so that it falls into the subsequent transmission equipment. Then, the push mechanism 5 is reset.
[0043] Step E: Reset the support platform 23: The drive mechanism 4 reverses the drive, causing the support platform 23 to slide in the reverse direction along the second horizontal direction Y, so that the support platform 23 returns to the initial position, the device returns to the initial waiting state, and waits for the next bundle of bamboo strips to be fed and processed, thus completing a complete work cycle.
[0044] This invention, through the synergy of the support plate 24, side baffle 25, side pushing mechanism 26, and pressing mechanism 27, forms a dual constraint on the bamboo strip end in both vertical and lateral directions before processing. This effectively suppresses the vertical jump and lateral slippage of the bamboo strip during cutting, improving the flatness of the end face and the accuracy of the tenoning. Furthermore, the connecting frame 3 enables synchronous translation of both ends, ensuring the precise length and toothing position of both ends. Moreover, through the sequential arrangement of the cutting mechanism 28, toothing mechanism 29, and pushing mechanism 5 along the sliding direction of the support platform 23, the bamboo strip can continuously complete the fixed-length trimming, end face toothing, and automatic unloading after one clamping and positioning. This effectively reduces the intensity of manual labor, reduces waiting and turnaround time, avoids repeated clamping, ensures the consistency of processing dimensions, and improves the level of production automation and processing efficiency.
[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the two ends of the connecting frame 3 are detachably connected to the support platform 23 of the two toothed assemblies 2, respectively. Specifically, the connection structure can be bolted, pin, snap-fit, etc.; the support seat 21 of one toothed assembly 2 is fixedly installed on the base 1, and the support seat 21 of the other toothed assembly 2 is slidably installed on the base 1 along the first horizontal direction X.
[0046] For example, the bottom surface of the support base 21 included in the active side of the toothed assembly 2 is fixedly mounted with slides on both sides along the second horizontal direction Y. The top surface of the base 1 is correspondingly provided with a slide rail extending along the first horizontal direction X. The slide rail and the slides slide in a sliding fit so that the toothed assembly 2 can slide smoothly relative to the base 1 along the first horizontal direction X, thereby adjusting the distance between the two toothed assemblies 2 to adapt to the processing needs of bamboo strips of different lengths.
[0047] When it is necessary to adjust the length of the bamboo strips to be processed, first separate the two ends of the connecting frame 3 from the two support platforms 23, then slide the movable side toothed assembly 2 along the first horizontal direction X of the base 1 to the target position that is compatible with the length of the bamboo strip to be processed, and finally replace the matching connecting frame 3 and detachably connect its two ends to the two support platforms 23 respectively, so as to restore the synchronous linkage relationship between the two support platforms 23.
[0048] Through the above design, the spacing between the two toothed assemblies 2 can be quickly adjusted, enabling the device to flexibly adapt to the processing needs of bamboo strips of different lengths. Moreover, when changing, only the connecting frame 3 needs to be disassembled, which significantly shortens the downtime for specification switching. While ensuring processing accuracy, it achieves multi-purpose use and effectively reduces the equipment cost for multi-specification production.
[0049] In some embodiments, such as Figure 3 and Figure 4 As shown, the side-pushing mechanism 26 includes: a support platform 261, a first cylinder 262, and a horizontal push plate 263, and its specific configuration is as follows: The support platform 261 is fixedly connected to the end of the bearing platform 23 on the side away from the side baffle 25 in the second horizontal direction Y, and the top surface of the support platform 261 is flush with the top surface of the support plate 24. It is used to provide an installation base and form a continuous support plane, thereby providing a horizontal guide reference for the sliding of the horizontal push plate 263, ensuring that the pushing action is smooth and the pushing height corresponds to the side of the bamboo strip. The first cylinder 262 is fixedly installed on the support platform 261 on the side away from the support plate 24, and is used as a lateral thrust source to provide horizontal driving force, and can achieve rapid response and adjustable thrust. The horizontal push plate 263 is slidably attached to the top surface of the support platform 261 and is fixedly connected to the drive end of the first cylinder 262. It is used to push the end of the bamboo strip towards the side baffle 25 along the second horizontal direction Y, ensuring that the pushing direction always moves in a straight line along the second horizontal direction Y, and avoiding uneven force on the bamboo strip due to deflection.
[0050] In the initial state, the first cylinder 262 is in the retracted state, and the horizontal push plate 263 is located on the support platform 261 near the first cylinder 262, with sufficient distance between it and the area on the support plate 24 where bamboo strips are placed, to facilitate the feeding of bamboo strips; after the end of the bamboo strip is placed on the support plate 24, the driving end of the first cylinder 262 extends out, pushing the horizontal push plate 263 to slide along the top surface of the support platform 261 toward the side baffle 25 until the front end of the horizontal push plate 263 contacts the side of the bamboo strip and applies a preset pressure.
[0051] Through the above design, a sliding reference coplanar with the bamboo strip support surface is provided for the horizontal push plate 263, ensuring that no vertical component force is generated during the pushing process, effectively preventing the bamboo strip from being pushed up, and making the side of the bamboo strip evenly stressed, thus providing reliable lateral constraint protection.
[0052] Based on the above embodiments, such as Figure 3 and Figure 4 As shown, the clamping mechanism 27 includes: a clamping frame 271, multiple second cylinders 272, and a clamping frame 273, and its specific configuration is as follows: The clamping frame 271 is L-shaped and installed on the top surface of the support platform 23. It includes an integrally connected vertical section 2711 and a horizontal section 2712. The vertical section 2711 is located on the side of the support plate 24 away from the side baffle 25 in the second horizontal direction Y. The horizontal section 2712 extends from the top of the vertical section 2711 to the top of the support plate 24. It is used to ensure that the clamping area covers the support plate 24 while avoiding interference with bamboo strip processing and cutting. Multiple second cylinders 272 are spaced apart on the top surface of the horizontal section 2712 for easy maintenance. The drive end of each second cylinder 272 extends vertically downward through the horizontal section 2712 to provide a vertical downward pressing power source. The spaced arrangement can distribute the force application points so that the pressing force is evenly applied to the ends of the whole bundle of bamboo strips. The clamping frame 273 is horizontally arranged between the support plate 24 and the horizontal section 2712, and is fixedly connected to the drive end of each second cylinder 272. It is used to clamp the end of the bamboo strip in the vertical direction. It can convert the concentrated driving force of the second cylinder 272 into a uniform downward pressure distributed in a planar manner. The frame structure reduces the weight and facilitates observation of the processing status while ensuring the contact area. Among them, the side of the horizontal push plate 263 near the side baffle 25 is provided with a clearance groove 264 that is adapted to the vertical section 2711, so that the horizontal push plate 263 does not interfere with the vertical section 2711 when it moves along the second horizontal direction Y, and ensures that the two actions of side pushing and pressing can be performed independently in the same spatial area.
[0053] In the initial state, the second cylinder 272 is in the retracted state, and the clamping frame 273 is located at a high position above the support plate 24, with enough space between it and the support plate 24 for bamboo strips to be fed. After the bamboo strip is placed on the support plate 24, the side push mechanism 26 is activated, and the horizontal push plate 263 moves along the second horizontal direction Y to press the bamboo strip laterally against the side baffle 25. During the movement, the clearance groove 264 just accommodates the vertical section 2711, so that the horizontal push plate 263 can pass through without obstruction and reach the clamping position. After the side-push clamping is completed, the synchronous drive ends of each second cylinder 272 extend downward, driving the clamping frame 273 to descend vertically until the lower surface of the clamping frame 273 contacts the upper surface of the bamboo strip end and applies a preset clamping force, fixing the bamboo strip to the support plate 24 in the vertical direction.
[0054] The above design ensures that the clamping force is applied evenly to the end of the bamboo strip, avoiding local deformation caused by single-point pressure. It also allows the lateral pushing and clamping actions to operate independently in the same space without interference, achieving dual constraints on the bamboo strip in both the vertical and lateral directions, effectively suppressing vertical runout during cutting.
[0055] In some embodiments, such as Figure 3As shown, the cutting mechanism 28 includes: a fixed frame 281, a first motor 282, a first cutting wheel 283, and a second cutting wheel 284, which are specifically configured as follows: The fixing frame 281 is installed on the top surface of the support base 21 to support other components at a preset height, ensuring that the relative position of the cutting wheel and the end of the bamboo strip is accurate in the vertical direction; The first motor 282 is mounted on the fixed frame 281, and its output shaft extends along the first horizontal direction X to provide a rotational power source to drive the first cutting wheel 283 and the second cutting wheel 284 to rotate synchronously at high speed to cut the ends of the bamboo strips. The first cutting wheel 283 is coaxially mounted on the output shaft of the first motor 282; The second cutting wheel 284 is coaxially mounted on the output shaft of the first motor 282; The second cutting wheel 284 is located on the side of the first cutting wheel 283 near the support plate 24 along the first horizontal direction X, and the outer diameter of the second cutting wheel 284 is smaller than the outer diameter of the first cutting wheel 283.
[0056] When the support platform 23 drives the clamped bamboo strip to slide along the second horizontal direction Y, and the end of the bamboo strip enters the cutting station, the first cutting wheel 283 with a larger outer diameter first cuts the part that exceeds the preset length. Then the second cutting wheel 284 with a smaller outer diameter assists in trimming the end face to eliminate burrs and tears, thereby obtaining a flat end face of a fixed length.
[0057] Through the above design, the bamboo strip end is first efficiently removed by the first cutting wheel 283 along the sliding direction, and then the end face is finely trimmed by the second cutting wheel 284, thus forming a graded progressive cutting. This not only ensures the processing efficiency of fixed-length and even cutting, but also effectively suppresses the cutting defects of the bamboo end face, providing a flat reference end face for subsequent tooth cutting. At the same time, the structure is compact, reliable, and easy to maintain.
[0058] Based on the above embodiments, such as Figure 4 As shown, the gear-opening mechanism 29 includes: a fixed plate 291, a transmission shaft 292, a gear-opening mechanism 293, and a second motor 294, the specific configuration of which is as follows: The fixing plate 291 is mounted on the fixing frame 281 and is used as the mounting base. The existing fixing frame 281 is used for support, making the structure more compact, while ensuring the relative position of the tooth-opening mechanism 29 and the cutting mechanism 28 in the second horizontal direction Y. The drive shaft 292 is vertically rotatably mounted on the fixed plate 291 to transmit the rotational motion of the second motor 294 to the gear 293, and at the same time bear the cutting load during machining. The gear 293 is coaxially fixedly connected to the upper end of the transmission shaft 292 and is used as a machining tool. It has cutting teeth distributed on its circumference. When the end face of the bamboo strip passes along the second horizontal direction Y in a high-speed rotation state, the end face is milled to process the tenon groove. The second motor 294 is mounted on the fixed plate 291, and its output shaft is connected to the transmission shaft 292 to provide a power source for gear cutting and drive the transmission shaft 292 and the gear 293 to rotate. The transmission connection method can be belt drive, chain drive or gear drive to achieve a suitable spatial arrangement.
[0059] Through the above design, the installation reference is shared with the cutting mechanism 28, which makes the layout compact and reduces errors; and the gear-type cutter completes the machining of all tooth grooves in one pass, resulting in high production efficiency and ensuring consistency.
[0060] In some embodiments, such as Figure 5 As shown, the drive mechanism 4 includes: a third motor 41, a transmission gear 42, and a transmission rack 43, and its specific configuration is as follows: The third motor 41 is mounted on the support platform 23 and is used as a power source to provide rotational torque. The reciprocating movement of the support platform 23 along the second horizontal direction Y can be realized by the forward and reverse rotation of the motor. The transmission gear 42 is coaxially mounted on the output shaft of the third motor 41, and is used to convert the rotational motion of the third motor 41 into linear motion along the extension direction of the transmission rack 43; The transmission rack 43 extends along the second horizontal direction Y and is mounted on the support beam 22. The transmission rack 43 meshes with the transmission gear 42 to convert the rotational motion of the transmission gear 42 into the linear movement of the support platform 23 relative to the support beam 22.
[0061] Through the above design, the direct conversion from the rotary motion of the motor to the linear reciprocating motion of the bearing platform 23 is realized. The transmission chain is short and has good rigidity, which effectively ensures the accuracy and stability of the feed displacement.
[0062] In some embodiments, such as Figure 5 As shown, the pushing mechanism 5 includes: a base 51, a longitudinal push plate 52, an extension frame 53, and a long push rod 54, and its specific configuration is as follows: The base 51 is mounted on the top surface of the support 21 to provide a support plane for the longitudinal push plate 52 to slide along the first horizontal direction X, and to ensure that the push mechanism 5 is installed in the correct position; The longitudinal push plate 52 is slidably mounted above the base 51 along the first horizontal direction X, and is used to push the bamboo strips away from the support plate 24 to provide a stable pushing surface; The extension frame 53 is installed on the side of the base 51 away from the support plate 24 in the first horizontal direction X, to provide sufficient installation space and stroke margin for the long push rod 54, and to ensure that the longitudinal push plate 52 has sufficient pushing distance to completely push the bamboo strip away from the processing area. The long push rod 54 is mounted on the extension frame 53 and extends along the first horizontal direction X. The drive end is fixedly connected to the longitudinal push plate 52 to provide linear reciprocating driving force along the first horizontal direction X. Its long stroke design ensures that the longitudinal push plate 52 can push out the bamboo strip completely. It can be achieved by using a cylinder, hydraulic cylinder or electric push rod.
[0063] During processing, the long push rod 54 is in a retracted state, and the longitudinal push plate 52 is located on the base 51 near the extension frame 53. There is a gap along the first horizontal direction X between its front end face and the bamboo strip placement area, so that the bamboo strip can pass smoothly through the front end area of the longitudinal push plate 52 when the support platform 23 moves along the second horizontal direction Y. After the teeth are opened, the support platform 23 moves forward along the second horizontal direction Y and sends the bamboo strip to the front end face of the longitudinal push plate 52. The side push mechanism 26 and the pressing mechanism 27 then release the end of the bamboo strip. Then the driving end of the long push rod 54 extends along the first horizontal direction X and pushes the longitudinal push plate 52 to push the processed bamboo strip out from the support plate 24 along the first horizontal direction X, pushing the bamboo strip to the subsequent transmission equipment.
[0064] The above design provides sufficient pushing stroke to ensure that the bamboo strip does not interfere with the pushing component when it moves, and realizes the connection between the pushing action and the processing path. The structure is compact and the operation is reliable, which can effectively complete the automatic lateral feeding of bamboo strips, reduce manual labor, and improve the continuous operation capability of the device.
[0065] In some embodiments, such as Figures 1 to 5 As shown, the top surface of the base 1 is provided with a material storage channel 11 extending along the first horizontal direction X, which is used to accommodate the debris generated during a long processing cycle, and facilitates that the debris generated by the two gear assemblies 2 can all be collected into the same channel, resulting in a simple structure. An inclined groove 211 is provided on the top surface of the support base 21. The inclined groove 211 extends downward along the first horizontal direction X to the side of the support base 21 and corresponds to the material storage channel 11. The tooth-opening mechanism 29 is located above the upper opening of the inclined groove 211, and is used to guide the debris generated by the tooth-opening process to the storage channel 11 through the inclined groove 211.
[0066] Through the above design, the debris generated during the tooth cutting process falls directly into the inclined groove 211 under the action of gravity, and automatically slides down along the groove surface into the storage channel 11 for centralized temporary storage. This achieves non-powered collection of processing waste, effectively avoids the accumulation and splashing of debris in the processing area, ensures the cleanliness of the device, and facilitates subsequent unified cleaning, thereby improving the operational reliability and maintenance convenience of the equipment.
[0067] In some embodiments, such as Figures 1 to 5 As shown, the support base 21 and the base 1 are vertically aligned on both sides along the second horizontal direction Y; the top surface of the support base 21 is also provided with a guide groove 212, which is located below the cutting mechanism 28. The guide groove 212 extends downward from the top surface of the support base 21 to the side of the support base 21 in the second horizontal direction Y.
[0068] Through the above design, the bamboo shavings generated during cutting fall directly into the guide trough 212 under the action of gravity, and automatically slide along the trough surface to be discharged laterally from the support base 21, thereby realizing the timely guidance and lateral discharge of cutting waste; effectively preventing the accumulation of cutting debris in the processing area, avoiding the interference of debris on the sliding parts of the bearing platform 23, and improving the cleanliness and maintenance convenience of continuous operation of the device.
