Description

Technical Field

[0001] This invention relates to the field of bamboo processing, and in particular to a continuous manufacturing apparatus and method for large-format bamboo laminated timber blanks. Background Technology

[0002] In the traditional bamboo laminated timber manufacturing process, 2.0-meter-long bamboo strips, after being finger-jointed, are manually spliced ​​one by one, with tape or nylon rope wrapped around the joints for fixation. Next, the spliced ​​bamboo strips are laid flat or side-jointed one by one to prepare flat or side-pressed boards by manually applying glue. Then, layers of glue are applied and laid to form the bamboo laminated timber blank. During this process, the positions of the finger-joints need to be manually identified to ensure that the joints are staggered and not on the same cross-section, preventing a decrease in strength due to concentrated joints. This manual assembly method is labor-intensive, inefficient, and has high production costs. It is also prone to operational errors, leading to inconsistent product quality. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a continuous manufacturing device and method for large-size bamboo laminated timber blanks, which realizes the continuous production of directional reconstituted bamboo laminated timber blanks, reduces labor intensity, improves production efficiency, and can meet the automated manufacturing needs of bamboo laminated timber blanks of different lengths.

[0004] The present invention adopts the following technical solution: A continuous manufacturing method for large-format bamboo laminated timber blanks employs a manufacturing apparatus comprising, in sequence, a feeding mechanism, a discharging mechanism, a splicing mechanism, a cutting mechanism, a gluing mechanism, a flipping mechanism, and a gathering and conveying mechanism. The feeding mechanism is used to stack and transport bundles of bamboo strips to subsequent multi-channels; the discharging mechanism is arranged in multiple channels to discharge bamboo strips synchronously to the rear; the lengthening mechanism heat-presses and lengthens the bamboo strips transported in the multiple channels; the cutting mechanism cuts the bamboo strips at an angle; the gluing mechanism applies glue to the bamboo strips synchronously and in a positioning manner; the flipping mechanism flips the bamboo strips 90 degrees to form an upright position; and the gathering and conveying mechanism gathers the bamboo strips into blanks. The manufacturing method includes the following steps: S1: The whole bundle of bamboo strips is fed by the feeding mechanism and then conveyed to the subsequent discharging mechanism; S2: The multiple channels of the discharge mechanism synchronously discharge and convey the bamboo strips to the subsequent extension mechanism; S3: The extension mechanism heat-presses and extends the bamboo strips that are conveyed from the front and back in the multi-channel, and then conveys them to the subsequent cutting mechanism. S4: The cutting mechanism synchronously and obliquely cuts the bamboo strips of the multi-channel bamboo strips, thereby causing the hot-pressed joints of the bamboo strips of each channel to be staggered, and then conveys them to the subsequent glue coating mechanism. S5: The gluing mechanism applies glue to the bamboo strips in the multi-channel synchronous positioning, and then conveys them to the subsequent flipping mechanism. S6: The flipping mechanism synchronously flips the bamboo strips in multiple channels, and then conveys them to the subsequent gathering and conveying mechanism; S7: The gathering and conveying mechanism synchronously gathers and assembles bamboo strips from multiple channels into blanks and outputs them.

[0005] As an improvement, the feeding mechanism includes a transversely arranged horizontal track and a placement mechanism movably arranged on the horizontal track. The placement mechanism is provided with a strip-shaped conveying channel. The upper part of the conveying channel is open for placing bamboo strips, and one end is open as the outlet end for bamboo strip output. The placement mechanism is provided with a pushing mechanism, which includes a pushing block and a first motor. The pushing block is driven by the first motor to move forward or backward along the conveying channel, thereby pushing the bamboo strips in the conveying channel out of the outlet end when moving forward. The placement mechanism is powered by a translation drive mechanism to adjust its position by translating along the horizontal track. The discharge mechanism includes multiple horizontally parallel material bins for conveying stacked bamboo strips. A conveyor chain is set at the bottom of the material bin for conveying the bamboo strips. A limiting mechanism is set at the top of the material bin for resisting the upper part of the bamboo strip for structural stability. A baffle is set at the outlet end of the material bin. The baffle and the conveyor chain form a material bin outlet for outputting a single bamboo strip. A conveying block is set on the conveyor chain. The conveying block is adapted to the thickness of a single bamboo strip to resist and push the bamboo strip. The splicing mechanism includes several splicing units connected end to end. Each splicing unit includes a feeding trough, a transferring mechanism, and a hot pressing mechanism. The feeding troughs are arranged in parallel for conveying and storing bamboo strips. The transferring mechanism is located at one end of the feeding trough and includes a transferring platform, a pressing groove, and a pressing block. The pressing groove and pressing block are set on the transferring platform. The pressing groove corresponds to the feeding trough for conveying and storing bamboo strips. The pressing block and pressing groove are vertically aligned. The pressing block is movable and presses and limits the bamboo strip when it descends into the pressing groove. The transferring platform is movable and adjusts the end position of the bamboo strip when it is pressed and moved horizontally. The hot pressing mechanism of each splicing unit receives the ends of the front and rear bamboo strips and performs hot pressing splicing on the front and rear bamboo strips. The cutting mechanism includes multiple parallel cutting grooves for conveying bamboo strips. Each cutting groove includes a front groove at the input end, a rear groove at the output end, and a cutting groove that is movably disposed between the front and rear grooves. The multiple cutting grooves are obliquely staggered at an angle on an adjustment frame. When the adjustment frame moves back and forth, it synchronously drives the multiple cutting grooves to adjust their positions. A cutting cylinder is installed on the upper part of the cutting groove, and a cutting blade is installed below the cutting cylinder. After the cutting groove moves to the predetermined position, the cutting blade is driven by the multiple cutting cylinders to move downward to cut the bamboo strip. The gluing mechanism has multiple parallel conveying troughs for conveying bamboo strips. The conveying troughs include a front support trough and a rear support trough, which are corresponding to each other. Two sets of gluing rollers are set between the two support troughs. When the bamboo strips are conveyed, they pass through the front support trough, the two sets of gluing rollers and the rear support trough in sequence. The two sets of gluing rollers apply glue to the bamboo strips when they are running. The rear support trough is equipped with support wheels to support the glued bamboo strips. The flipping mechanism includes a conveying mechanism and a flipping device arranged in sequence. The conveying mechanism includes a transport trough and a second conveying chain. Multiple transport troughs are arranged in parallel on the second conveying chain. The multiple transport troughs transport bamboo strips stored in the transport troughs back and forth through the forward and backward movement of the second conveying chain. The flipping device is located at the output end of the second conveying chain. The flipping device includes an inner gear sleeve, an outer sleeve, a rack, and a flipping cylinder. The inner gear sleeves are fitted inside the outer sleeves and are arranged in corresponding numbers at the output end of the second conveying chain, facing the transport troughs to receive bamboo strips. The outer sleeves are fixedly set. The flipping cylinder is connected to the rack. The rack is arranged horizontally and meshes with each inner gear sleeve. When the flipping cylinder drives the rack to reciprocate, it flips the inner gear sleeve by 90 degrees. The gathering and conveying mechanism includes several conveying channels for transporting bamboo strips. These channels are arranged from sparse to dense from the input end to the output end, thereby gathering the bamboo strips and outputting them backward.

[0006] As an improvement, the discharge mechanism also includes a clamping mechanism. The clamping mechanism is located at the rear end of the hopper and corresponds to the hopper outlet. The clamping mechanism includes a guide trough for receiving and conveying bamboo strips, and a movable clamping member located on the upper part of the guide trough. The upper end of the clamping member is rotatably mounted on a support frame, and the lower end abuts against the guide trough, thereby limiting the upper part of the bamboo strips that pass through the guide trough and the clamping member. The clamping member abuts against the guide trough through an elastic member. When the bamboo strips are conveyed and push open the clamping member, the elastic member is compressed, accumulating elastic pressure for the clamping member.

[0007] As an improvement, the limiting mechanism includes a swing arm, rollers, and a telescopic rod. The swing arm is swayably mounted on the upper part of the hopper, and rollers are mounted on the lower part of the swing arm. The rollers abut against the upper part of the bamboo strips for structural stability and roll when the bamboo strips move. One end of the telescopic rod is swayably mounted on the upper part of the hopper, and the other end is swayably connected to the swing arm. The telescopic rod drives the swing arm to rise or fall. When the telescopic rod drives the swing arm to rise, it opens the upper space of the hopper for subsequent bamboo strips to be fed into the hopper. When the telescopic rod drives the swing arm to fall, it provides a resisting force to keep the swing arm abutting against the bamboo strips.

[0008] As an improvement, the placement mechanism includes a main support, a base frame, and several limiting rods. The bottom of the main support is slidably mounted on a transverse track. The main support and several limiting rods form a conveying channel on both sides of the base frame. The base frame is used for bamboo strip support and placement, and the main support and several limiting rods limit the movement on both sides.

[0009] As an improvement, the conveying trough mechanism also includes an upper pressing trough located above the support trough, forming a channel for bamboo strips to pass through between the support trough and the upper pressing trough; a support wheel is provided at the upper pressing trough above the support trough in the rear section to provide upper support for the glued bamboo strips, and the surfaces of the support wheels on the support trough and the upper pressing trough in the rear section have transmission teeth.

[0010] As an improvement, the glue-applying roller assembly includes a main roller body and an auxiliary roller body. The main roller body is a rough roller, and the auxiliary roller body is a smooth roller. The upper and lower main roller bodies clamp and roll the bamboo strips to complete the glue application. The auxiliary roller body rolls in conjunction with the main roller body to evenly apply the glue on the main roller body.

[0011] As an improvement, the material transfer mechanism also includes a material transfer cylinder and a material transfer motor. The two sides of the material transfer platform are slidably mounted on the track. The material transfer cylinder is connected to the material transfer platform and drives the material transfer platform to move and adjust the position of the bamboo strip ends when the material transfer cylinder is working. The material transfer motor is mounted on the upper frame of the material transfer platform and connected to the pressure block. When the material transfer motor is working, it drives the pressure block to rise and fall.

[0012] As an improvement, the output end of the gear inner sleeve extends out of the outer sleeve and an external gear is set on the outer periphery, which meshes with the rack; the gear inner sleeve has a rectangular inner frame that runs through both ends, the rectangular inner frame is located in the outer sleeve, and the bamboo strip is conveyed by the transport groove and extends into the rectangular inner frame for limiting.

[0013] As an improvement, a second limiting mechanism is provided before the flipping device. The second limiting mechanism includes a limiting cylinder, a connecting rod, and limiting wheels. The limiting cylinder is set on the frame, and the number of limiting wheels corresponds to the number of transport grooves. The limiting wheels are rotatably set on the connecting rod. The end of the connecting rod is connected to the limiting cylinder and is driven by the limiting cylinder to lift and lower. The limiting wheels are set above the gear inner sleeve and the transport groove. When the limiting cylinder drives the connecting rod to lift and lower, the height of the limiting wheels is adjusted, thereby adjusting the distance between the limiting wheels and the transport groove.

[0014] The beneficial effects of this invention are: 1. The device of the present invention can place dozens of bamboo strips in a storage bin, realizing automated feeding and discharging of bamboo strips, greatly improving production efficiency and automation level, and reducing labor intensity.

[0015] 2. The bamboo strip joints are hot-pressed using a synchronous hot-pressing curing method, which greatly improves production efficiency compared with traditional processing methods, and does not affect the continuity of subsequent processing.

[0016] 3. The manufacturing efficiency of bamboo engineered wood blanks can be changed from manually splicing one blank at a time to batch splicing 5-10 blanks continuously, which significantly improves the processing efficiency. Furthermore, due to multi-channel synchronous splicing and hot pressing curing, mass production has been achieved.

[0017] 4. By adopting technologies such as synchronous fixed-length bamboo strip cutting, automatic gluing, and assembly, we have achieved efficient manufacturing of infinitely long bamboo strips, automatic gluing of spliced ​​bamboo strips, and staggered assembly. This has improved the continuous production of oriented reconstituted bamboo laminated timber blanks, reduced labor intensity, and increased production efficiency, and can meet the automated manufacturing needs of bamboo laminated timber of different lengths.

[0018] 5. This invention can improve the processing efficiency of bamboo laminated timber blanks, reduce the number of personnel required, liberate labor, thereby improving economic benefits and facilitating large-scale industrial production. Attached Figure Description

Detailed Implementation

[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-13 The image shows a specific embodiment of the continuous manufacturing apparatus and method for large-size bamboo laminated timber blanks of the present invention.

[0035] The manufacturing method of this embodiment employs a manufacturing apparatus. During implementation, the feeding mechanism A first feeds bamboo strips: a bundle of bamboo strips is placed from top to bottom into the strip-shaped conveyor channel A3 on the placement mechanism A2, and the binding rope is cut. The conveyor channel A3 can be adjusted in width to accommodate bundles of bamboo strip blanks of different sizes. Next, the feed inlet is selected: multiple sets of subsequent material hoppers B3 are arranged horizontally in parallel. Before feeding, it is determined which subsequent material hopper B3 will feed. The translation drive mechanism A6 is activated to move the placement mechanism A2 along the transverse track A5 to the corresponding material hopper B3 feed inlet. Then, the bamboo strips are fed: after the placement mechanism A2, containing bundles of bamboo strip blanks, is aligned with the material hopper B3 feed inlet, the first motor A42 controls the movement of the push block A41. The push block A41 moves forward, pushing the bamboo strip blanks into the corresponding material hopper B3. During this forward movement, the uneven bamboo materials are automatically aligned, achieving automatic alignment and feeding of the bamboo materials to the discharge mechanism B.

[0036] The conveyor chain B2 of the discharge mechanism B is composed of several grooved chain links connected end to end; the conveyor chain B2 is wound around a sprocket, which is connected to a power source such as a motor. The hopper B3 is enclosed on both sides by plate structures, forming a strip-shaped space for receiving and conveying. In use, a specific hopper B3 receives bamboo strips conveyed by the feeding mechanism, typically stacked in groups of ten; then the bamboo strips are buffered and compressed. After the bamboo strips reach the hopper B3, the upper limiting mechanism B4 presses down on the bamboo strips to compress them, thus preventing the space occupied by the natural bending of the bamboo strips. Following this, bamboo strips are continuously and evenly discharged. As conveyor chain B2 operates, it moves the bamboo strips towards the output end. The gap between baffle B5 and conveyor chain B2 forms the hopper outlet B31, which is the thickness of one bamboo strip. This prevents excess bamboo strips from being carried out of the hopper trough B3 by conveyor chain B2. During operation, conveyor block B21 abuts against the bottommost bamboo strip from behind, causing the bamboo strip to exit from hopper outlet B31, achieving the goal of discharging one strip at a time. As conveyor chain B2 operates, conveyor block B21 can circulate, pushing each bamboo strip out evenly and sequentially. By setting multiple hopper troughs B3, multiple bamboo strips can be discharged simultaneously and evenly, sequentially conveying them to the extension mechanism C.

[0037] The lengthening mechanism C sets the number of lengthening units C0 according to the length of the bamboo strips to be lengthened. The lengthening units C0 are connected end to end, and the length of each lengthening unit C0 is approximately equal to the length of the bamboo strip to be lengthened. The bamboo strips are conveyed to the lengthening units C0, and the number of bamboo strips conveyed in each batch corresponds to the number of lengthening units C0. Then, the preceding mechanism pushes the corresponding number of bamboo strips into the corresponding number of lengthening units C0. Specifically, the bamboo strips are stored in the feeding trough C2. The size of the feeding trough C2 is adapted to the bamboo strips, thus effectively limiting the bamboo strips and facilitating the alignment of the bamboo strips. Each extension unit C0 has multiple parallel feeding grooves C2, operated by a material transfer mechanism C3. This mechanism clamps and stabilizes the bamboo strips while simultaneously displacing them so that the ends of the strips accurately align with the hot-pressing mechanism C4. Specifically, the material transfer mechanisms C3 of each extension unit C0 operate sequentially: the first material transfer mechanism C3 clamps the first batch of bamboo strips and moves the ends to the hot-pressing mechanism C4. The front ends of the first batch of bamboo strips are restrained by the preceding batch, effectively defining their stopping position. As subsequent material transfer mechanisms C3 operate, the ends of the remaining bamboo strips all contact the hot-pressing mechanism C4, achieving a neat and tight engagement. The pressing groove C32 is sized to fit the bamboo strips, effectively limiting their movement and facilitating alignment. The pressing block C33, after descending into the pressing groove C32, presses the bamboo strips from above, providing stable clamping and restraint. The transfer table C31 can be moved horizontally, and multiple clamping grooves C32 are arranged in parallel on it, allowing for the clamping and horizontal movement of bamboo strips in the same batch simultaneously. Each group of hot pressing mechanisms C4 completes the heating and curing at the ends of the bamboo strips to be hot pressed, realizing the mechanized and automated synchronous splicing of multiple bamboo strips. After the processing of this batch of bamboo strips is completed, when the next batch of bamboo strips is fed into the splicing mechanism C, it can push the bamboo strips to the cutting mechanism D of the next process.

[0038] The cutting mechanism at point D consists of multiple cutting grooves that receive the bamboo strips. The front groove D2 at the input end and the rear groove D4 at the output end are relatively long, used to accommodate and support the bamboo strips, working in conjunction with the middle cutting groove D3 to cut the bamboo strips. Figure 9As shown, multiple cutting grooves D3 are set at an angle and staggered on an adjustment frame D5. In practice, the hot pressing extension positions of the bamboo strips received by each cutting groove group are consistent. By setting the cutting blades D8 of the cutting grooves D3 at an angle and staggering them, the cutting positions are staggered in an orderly manner. When this batch of bamboo strips is conveyed backward for billet assembly, the extension positions of the billet are ensured to be staggered, so that the joints are not on the same cross-section, preventing the strength from decreasing due to the concentration of joint positions. The adjustment frame D5 is mounted on rails on both sides. The adjustment frame D5 can move via the screw-slider mechanism D6. The slider in the screw-slider mechanism D6 is located at the lower part of the adjustment frame D5. The screw is rotatably inserted through the slider. The screw is connected to a power source such as a servo motor. The servo motor drives the rotation of the screw, which in turn drives the movement of the adjustment frame D5. By presetting the length of the bamboo strip to be processed, the cutting length of the bamboo strip is determined, and the adjustment frame D5 is controlled to move to the appropriate position. After the bamboo strip is conveyed to the rated length in the cutting groove, the cutting cylinder D7 drives the cutting blade D8 to cut the bamboo strip. The cut bamboo strip continues to be conveyed backward to the gluing mechanism E.

[0039] The conveying trough mechanism E2 of the gluing mechanism E corresponds one-to-one with the material hopper B3 of the discharging mechanism B. Multiple conveying trough mechanisms E2 share two sets of gluing rollers E3, that is, two sets of gluing rollers E3 are arranged perpendicular to the conveying direction of the bamboo strips, thereby realizing the synchronous gluing operation of multiple bamboo strips during conveying. Bamboo strips are conveyed into the front support groove E21, where they are structurally positioned and conveyed in an orderly manner. As the bamboo strip exits the front support groove E21 and reaches the area between the two sets of glue-coating rollers E3, the two sets of glue-coating rollers E3 are driven to rotate by a power mechanism such as a motor. The two sets of glue-coating rollers E3 are pre-filled with glue manually or by an external glue delivery mechanism. As the bamboo strip passes through, the two sets of glue-coating rollers E3 roll over both sides of the bamboo strip, ensuring that the glue is evenly applied to both sides. Afterward, the bamboo strip enters the rear support groove E21, where it is positioned and continues to be conveyed. Support wheels E22 are installed within the rear support groove E21. These support wheels rotate in conjunction with the conveying of the bamboo strip, providing support while preventing the bamboo strip from contacting the bottom of the support groove E21. This prevents the glue from sticking to the groove, ensuring that the glue on the surface of the bamboo strip is not damaged and reducing contamination of the equipment. The bamboo strips output from the support groove E21 at the rear are conveyed to the flipping mechanism F.

[0040] The multiple transport troughs F21 of the flipping mechanism F correspond to the support trough E21 of the rear section. The second conveyor chain F22 is wound around the sprocket in a ring and connected to the external drive motor to run in the forward or reverse direction. The multiple transport troughs F21 on the second conveyor chain F22 are synchronously advanced to the flipping device F3 or reset to the feeding end. Multiple bamboo strips are received one-to-one by multiple transport troughs F21. A drive motor then drives the conveyor chain F22, which transports the bamboo strips to the turning device F3. The bamboo strips extend into the inner sleeve F31 of the gear, where their inner diameter limits their movement. Then, the turning cylinder F34 is activated, causing the rack F33 to translate, which in turn rotates the inner sleeve F31 within the outer sleeve F32 by 90 degrees. This allows each bamboo strip in the inner sleeve F31 to complete a 90-degree turn. The turned bamboo strips are then powered by a power mechanism at the output of the turning device F3 to be output to the gathering and conveying mechanism G. After resetting, the multiple transport troughs F21 can then transport and turn the next batch of bamboo strips.

[0041] The gathering and transmission mechanism G has several transmission channels that receive the bamboo strips being transported. These several transmission channels are like... Figure 1 As shown, the bamboo strips are arranged from sparse to dense, which then gathers and assembles the bamboo into a blank and outputs it. It can be further connected to a hot press to complete the hot pressing and curing of the blank in a special hot press for bamboo composite materials.

[0042] As an optimization, to ensure smoother bamboo strip transport, a transport mechanism H can be placed at locations where power supply or buffering of the bamboo strips is required. For example... Figure 1 As shown, a set of transport mechanisms H is arranged between the cutting mechanism D and the gluing mechanism E. Transport mechanism H has a corresponding number of transport channels, which define the left and right positions of the bamboo strips. The lower track is used for forward transport of the bamboo strips, and a buffer is provided when the bamboo strips stop. An upper pressure roller is used for limiting and stabilizing the bamboo strips. Transport mechanism H can be flexibly set between the other two sets of mechanisms as needed to transport or buffer the bamboo strips.

[0043] As an improved specific implementation, the discharge mechanism B also includes a pressing mechanism B6. The pressing mechanism B6 is located at the rear end of the hopper trough B3 and corresponds to the hopper outlet B31. The pressing mechanism B6 includes a guide groove B61 for receiving and conveying bamboo strips, and a pressing member B62 that is movable on the upper part of the guide groove B61. The upper end of the pressing member B62 is rotatably mounted on a support frame B63, and the lower end abuts against the guide groove B61 to limit the bamboo strips that pass through the guide groove B61 and the pressing member B62. The pressing member B62 abuts against the guide groove B61 through an elastic member. When the bamboo strips are conveyed and push open the pressing member B62, the elastic member is compressed, accumulating elastic pressure for the pressing member B62.

[0044] like Figure 4 , 5 As shown in Figure 6, the clamping mechanism B6 provides further stability for the overall structure during discharge. After the bamboo strips are pushed out of several hoppers B3, they are clamped by the clamping mechanism B6. The guide trough B61 supports the bamboo strips and guides them to the subsequent mechanism. The clamping member B62 presses down on the bamboo strips to prevent them from bending naturally, thus ensuring that the bamboo strips are accurately aligned with the entrance position of the subsequent mechanism when they are output. The rotating ends of the clamping member B62 and the support frame B63 are close to the hopper trough B3, and the open ends face the output side. After the bamboo strips are conveyed into the guide trough B61 and reach the clamping member B62, they can be pushed upward to open the clamping member B62 for smooth passage, while the clamping member B62 provides upper limit. The elastic element is not shown in the figure. In specific implementation, the elastic element can be a spring with suitable elasticity, which abuts against the upper part of the lower end of the clamping element B62, thereby making the clamping element B62 tightly and stably press against the guide groove B61. When the bamboo strip is conveyed, it lifts the clamping element B62 and compresses the spring, and the bamboo strip is stably pressed by the elastic force and output stably. After the bamboo strip is conveyed away, the spring releases its elastic force, causing the clamping element B62 to return to its original position against the guide groove B61. The guide groove B61 is further configured as a flared opening. Figure 5 As shown, the flared end, i.e., the input end, is larger and the output end is smaller, which allows the bamboo strips to be smoothly guided into the guide groove B61 and stably limited to the left and right positions in the reduced space during conveying, which is conducive to accurate alignment of the output.

[0045] As an improved specific implementation, the limiting mechanism B4 includes a swing arm B41, a roller B42, and a telescopic rod B43. The swing arm B41 is swayably mounted on the upper part of the hopper trough B3, and the roller B42 is mounted on the lower part of the swing arm B41. The roller B42 abuts against the upper part of the bamboo strip for structural stability and rolls when the bamboo strip moves. One end of the telescopic rod B43 is swayably mounted on the upper part of the hopper trough B3, and the other end is swayably connected to the swing arm B41. The telescopic rod B43 drives the swing arm B41 to rise or fall. When the telescopic rod B43 drives the swing arm B41 to rise, it opens the upper space of the hopper trough B3 to allow subsequent bamboo strips to be replenished and transported into the hopper trough B3. When the telescopic rod B43 drives the swing arm B41 to fall, it provides a resisting force to make the swing arm B41 abut against the bamboo strip.

[0046] like Figure 4 , 5As shown in Figure 6, the swing arm B41 has a degree of freedom in circular motion. When the swing arm B41 swings down, the roller B42 at its lower end contacts the bamboo strip, thus stabilizing the bamboo strip. During bamboo strip conveying, the roller B42 rolls in coordination with the movement of the bamboo strip, ensuring smooth conveying of the bamboo strip without damaging it. The upper end of the telescopic rod B43 has a degree of freedom in circular motion. When the telescopic rod B43 retracts, it drives the swing arm B41 to rise, allowing bamboo strips to be added to the hopper 3 at any time by the preceding feeding mechanism. The bamboo strips can be pushed in when the horizontal height of the conveying channel A3 is higher than the height of the bamboo strips in the hopper 3. The added bamboo strips fall and stack on top. The process of adding bamboo strips does not affect the continuous discharge of bamboo strips at the bottom. After the addition is completed, the telescopic rod B43 can be driven to extend and then descend, allowing the swing arm B41 to contact the bamboo strip again for structural stability. After the bamboo strips at the bottom are conveyed out, the telescopic rod B43 can press down on the bamboo strips to make them neat. Multiple sets of limiting mechanisms B4 are set at intervals along the conveying direction of the hopper trough B3 to effectively compress the bamboo strips at multiple positions and prevent them from bending.

[0047] As an improved specific implementation, the placement mechanism A2 includes a main support A21, a base frame A22 and several limiting rods A23. The bottom of the main support A21 is slidably mounted on the transverse track A5. The main support A21 and several limiting rods A23 form a conveying channel A3 on both sides of the base frame A22. The base frame A22 is used for supporting the placement of bamboo strips, and the main support A21 and several limiting rods A23 are limited on both sides.

[0048] like Figure 2 , 3 As shown, the main support A21 forms the main support structure, which facilitates the installation of a slider and a transverse track A5 at the bottom, and facilitates the arrangement of a pushing mechanism A4 at the top; the base frame A22 is set as a long rod for supporting and placing bamboo strips; the other side is enclosed by several limiting rods A23 to form a conveying channel A3; the spacing between the limiting rods A23 and the main support A21 can be adjusted through the existing adjustment structure, thereby accommodating bundles of bamboo strip blanks of different sizes and adapting to different feeding requirements.

[0049] As an improved specific implementation, several limiting rods A23 are vertically spaced on one side of the base frame A22 to block the bamboo strips and reduce friction between the structures by the spacing.

[0050] like Figure 2 , 3 As shown, preferably, several limiting rods A23 can be set according to the length of the conveying channel A3. The limiting rods A23 are set vertically at intervals to reduce friction when pushing bamboo strips and improve feeding smoothness. The spacing of the limiting rods A23 can be set separately to adjust the spacing, thereby reducing the difficulty and cost of setting up the structure.

[0051] As an improved specific implementation, the pushing mechanism A4 also includes a frame A40 for mounting the push block A41 and the first motor A42, a gear A43 disposed on the output shaft of the first motor A42, and a tooth condition A44 disposed on the placement mechanism A2. The gear A43 and the tooth condition A44 mesh with each other. When the first motor A42 is working, the gear A43 moves along the tooth condition A44, thereby driving the frame A40 and the push block A41 thereon to move forward or backward along the conveying channel A3.

[0052] like Figure 3 As shown, the frame A40 is configured to slide on the placement mechanism A2, specifically on the main support A21. The gear condition A44 is set along the main support A21. When the first motor A42 drives, the gear A43 rotates and moves along the gear condition A44, realizing the movement of the frame A40 and the push block A41. The first motor A42 is preferably a servo motor, thereby performing precise start and stop control on the operation of the push block A41.

[0053] As an improved specific implementation, the placement mechanism A2 is also provided with a longitudinal track A45 parallel to the tooth condition A44, and the frame A40 is slidably mounted on the longitudinal track A45.

[0054] like Figure 3 As shown, the frame A40 is equipped with a slider that cooperates with the longitudinal track A45, so that the frame A40 is stably set on the main support A21, and the frame A40 can be smoothly slid along the longitudinal track A45 to adjust its position when the gear A43 and the gear A44 mesh and drive.

[0055] As an improved specific implementation, the translation drive mechanism A6 includes a second motor A61, a lead screw A62, and a nut seat A63. The nut seat A63 is disposed on the placement mechanism A2. The lead screw A62 is rotatably arranged laterally. The second motor A61 is connected to the lead screw A62 for driving. The nut seat A63 is sleeved on the lead screw A62. Thus, when the second motor A61 drives the lead screw A62 to rotate, it drives the nut seat A63 and the placement mechanism A2 to move.

[0056] like Figure 3 As shown, the second motor A61 can preferably be a servo motor, which is started and stopped by a control module to ensure that the placement mechanism A2 is translated to a precise position so that the conveying channel A3 is aligned with the subsequent hopper trough B3. Specifically, the placement mechanism A2 has several sets of nut seats A63 set on the lower part of the main support 21, and the nut seats A63 are sleeved on the lead screw A62. When the second motor A61 drives the lead screw A62 to rotate, it can drive the nut seats A63 to translate along the lead screw A62, thereby driving the main support A21 to translate along the transverse track A5, and the overall drive is stable.

[0057] As an improved specific implementation, multiple sets of transverse tracks A5 are arranged at intervals, allowing the placement mechanism A2 to be supported on them and to cooperate with them.

[0058] like Figure 2 , 3 As shown, the transverse track A5 can be set on both sides of the frame and at the position of the limit rod A23 to ensure uniform force distribution and stable structural support.

[0059] As an improved specific implementation, the material transfer mechanism C3 further includes a material transfer cylinder C35 and a material transfer motor C34. The two sides of the material transfer platform C31 are slidably mounted on the track. The material transfer cylinder C35 is connected to the material transfer platform C31, and when the material transfer cylinder C35 is working, it drives the material transfer platform C31 to move and adjust the end position of the bamboo strip. The material transfer motor C34 is mounted on the upper frame of the material transfer platform C31 and connected to the pressing block C33. When the material transfer motor C34 is working, it drives the pressing block C33 to rise and fall.

[0060] like Figure 7 , 8 As shown, the transfer table C31, with its number of clamping grooves C32, is designed to accommodate the needs of conveying and clamping multiple bamboo strips. Its sides are mounted on tracks via sliders, enabling stable translation along the bamboo strip conveying direction. The translational force of the transfer table C31 is provided by the transfer cylinder C35. The transfer cylinder C35, while ensuring stable translation, also provides clamping force for the mating positions of the bamboo strips, guaranteeing stable engagement, evenness during hot pressing, and improved processing quality. A frame is erected according to the width of the transfer table C31. A suitable number of transfer motors C34 are spaced on the frame, and pressure blocks C33 are spaced below each transfer motor C34. When the transfer motors C34 operate, they drive the pressure blocks C33 to rise and fall, and the downward pressure of the transfer motors C34 keeps the bamboo strips in the clamping grooves C32 firmly clamped.

[0061] As an improved specific implementation, the feeding trough C2 includes a bottom trough C21 and an upper plate C22. The bottom trough C21 is used to store bamboo strips along its length. The upper plate C22 is disposed above the bottom trough C21, and a channel for bamboo strips to pass through is formed between the upper plate C22 and the bottom trough C21.

[0062] like Figure 7 , 8 As shown, the sidewall of the bottom groove C21 adapts to the width of the bamboo strip, thereby effectively limiting and stabilizing the bamboo strip for conveying along its length. When the bamboo strip is long, it will naturally bend. By setting an upper plate C22 above the bottom groove C21, the bottom groove C21 and the upper plate C22 cooperate to form a channel for the bamboo strip to pass through, which can effectively prevent the natural bending of the bamboo strip during conveying and make the conveying more orderly.

[0063] As an improved specific implementation, the hot pressing mechanism C4 includes a hot pressing groove C41, a hot pressing component C42, and a hot pressing motor C43. The hot pressing groove C41 is for bamboo strips to be placed in it and transported and stored along its length. The hot pressing component C42 and the hot pressing groove C41 are vertically aligned. The hot pressing motor C43 is set on the upper frame and connected to the hot pressing component C42. When the hot pressing motor C43 is working, it drives the hot pressing component C42 to rise and fall.

[0064] like Figure 7 As shown, the number of hot-pressing grooves C41 is set according to the number of bamboo strips hot-pressed in a single batch of parallel arrangement of the extension unit C0. Its width is adapted to the width of the bamboo strips, so that the bamboo strips are well limited when they are transported into the hot-pressing grooves C41, which is conducive to the alignment and engagement of the end joints of the front and rear bamboo strips. The hot-pressing component C42 is provided with a groove structure adapted to the shape of the bamboo strips. The groove structure, together with the hot-pressing grooves C41, forms an upper and lower pressing structure to act on the end position of the bamboo strips to be hot-pressed. An appropriate number of hot-pressing motors C43 are set at intervals on the frame. The hot-pressing component C42 is set below the hot-pressing motors C43. When the hot-pressing motors C43 are working, they drive the hot-pressing component C42 to rise and fall. The bamboo strips are pressed and stabilized by the hot-pressing grooves C41 and the hot-pressing component C42 by the downward pressure of the hot-pressing motors C43. The heating and extension process of the bamboo strips is completed when the hot-pressing grooves C41 and the hot-pressing component C42 are heated by the heat source.

[0065] As an improved specific implementation, the conveying groove mechanism E2 also includes an upper pressing groove E23 located above the support groove E21, forming a channel for bamboo strips to pass through between the support groove E21 and the upper pressing groove E23; a support wheel E22 is provided at the upper pressing groove E23 above the support groove E21 in the rear section to provide upper support for the glued bamboo strips, and the surfaces of the support wheel E22 on the support groove E21 and the upper pressing groove E23 in the rear section have transmission teeth.

[0066] like Figure 10 , 11As shown, when bamboo strips are long, they naturally bend. By setting an upper pressure groove E23, the support groove E21 and the upper pressure groove E23 cooperate to form a channel for the bamboo strip to pass through, which can effectively prevent the bamboo strip from bending naturally during transportation, making the transportation more orderly. Depending on the thickness of the bamboo strip, the distance between the support groove E21 and the upper pressure groove E23 can be set slightly larger than the bamboo strip by 0.5mm, so as not to affect the normal transportation of the bamboo strip while restricting the bending of the bamboo strip. The upper and lower support wheels E22 are set accordingly. The upper and lower support wheels E22 rotate in conjunction with the transportation of the bamboo strip. While providing support, they prevent the bamboo strip from contacting the upper and lower surfaces of the support groove E21, thereby preventing glue from sticking to the groove, ensuring that the glue on the surface of the bamboo strip is not damaged, and reducing contamination of the equipment. The distance between the upper and lower support wheels 22 can be set slightly larger than the bamboo strip by 0.5mm, so as not to affect the normal transportation of the bamboo strip while restricting the bending of the bamboo strip. The surface of the support wheel E22 has a transmission tooth structure arranged along the circumference, and preferably has multiple tooth structures spaced apart in the radial direction, thereby reducing the contact between the support surface and the bamboo strip, thus reducing the possibility of the glue on the surface of the bamboo strip being damaged.

[0067] As an improved specific implementation, the front end of the upper pressure groove E23 has an upwardly curved guide rim E24.

[0068] like Figure 10 , 11 As shown, the entrance positions of the upper pressure groove E23 of the two channels are widened by setting an upward-curving guide eaves E24, which makes the entrance openings of the support groove E21 and the upper pressure groove E23 open outward, thus facilitating the smooth transport of bamboo strips. The bamboo strips can enter the channel along the narrowing of the guide eaves E24.

[0069] As an improved specific implementation, the glue-coating roller group E3 includes a main roller body E31 and a secondary roller body E32. The main roller body E31 is a rough roller, and the secondary roller body E32 is a smooth roller. The upper and lower main roller bodies E31 clamp and roll the bamboo strip to complete the glue coating. The secondary roller body E32 rolls in conjunction with the main roller body E31 to evenly spread the glue on the main roller body E31.

[0070] like Figure 10 , 11 As shown, by setting up a structure where the main roller E31 and the auxiliary roller E32 roll in coordination, when glue is replenished manually or by an externally connected glue delivery mechanism, it can be added to both the main roller E31 and the auxiliary roller E32 simultaneously. The rolling of the main roller E31 and the auxiliary roller E32 ensures that the glue is evenly distributed on the main roller E31, thereby improving the uniformity of glue application and ensuring the quality of the application. In practical implementation, the smooth roller of the auxiliary roller E32 is less prone to glue residue, allowing the glue to be more fully squeezed onto the rough roller surface of the main roller E31, ensuring that the glue is evenly distributed on the rough roller, thus guaranteeing the uniformity of the application of glue to the bamboo strips by the rough roller, i.e., the main roller E31.

[0071] As an improved specific implementation, the two ends of the main roller body E31 and the auxiliary roller body E32 are mounted on the roller adjustment mechanism E5. The roller adjustment mechanism E5 includes a fixed frame E51, a movable frame E52 and a rotating block E53. The fixed frame E51 is set on the machine frame E1, and the movable frame E52 is slidably set on the fixed frame E51. The main roller body E31 and the auxiliary roller body E32 are respectively set on the fixed frame E51 and the movable frame E52 through their respective rotating blocks E53. The distance between the main roller body E31 and the auxiliary roller body E32 is adjusted by the movable frame E52 sliding on the fixed frame E51.

[0072] like Figure 10 , 11 As shown, in practical implementation, the distance between the main roller E31 and the auxiliary roller E32 can be finely adjusted through the roller adjustment mechanism E5. This serves two purposes: firstly, it adjusts the glue thickness; secondly, it allows the main roller E31 and the auxiliary roller E32 to be separated during maintenance shutdowns for easy cleaning and replacement. Specifically, the rotating block E53 is rotatably mounted on the fixed frame E51 and the movable frame E52 via a bearing structure, ensuring the normal rotation of the main roller E31 and the auxiliary roller E32. The movable frame E52 is slidably mounted on the fixed frame E51 via a track and slider structure. Adjustment of the movable frame E52 is achieved through a screw-slider structure. The screw is connected to an external power component or a handwheel. By rotating the screw electrically or manually, the slider on the movable frame E52 moves along the screw, causing the movable frame E52 to slide along the track, thus adjusting the relative position of the fixed frame E51 and the movable frame E52.

[0073] As an improved specific implementation, a glue collection trough E4 for receiving glue is provided below the glue coating roller group E3; the glue collection trough E4 has a V-shaped cross section and is arranged at an angle.

[0074] like Figure 10 , 11 As shown, the glue collection trough E4 covers the entire length of the glue application roller assembly E3, and can catch the glue flowing down during the glue application process, thereby reducing glue waste and improving utilization. The inclined V-shaped glue collection trough E4 concentrates the glue towards the center and flows to the lower end, where it can be collected into a collection mechanism via a further designed outlet for transfer and reuse.

[0075] As an improved specific implementation, the output end of the gear inner sleeve F31 extends out of the outer sleeve F32 and an external gear F311 is provided on the outer periphery. The external gear F311 meshes with the rack F33. The gear inner sleeve F31 has a rectangular inner frame F312 that is open at both ends. The rectangular inner frame F312 is located in the outer sleeve F32. The bamboo strip is conveyed by the transport groove F21 and extends into the rectangular inner frame F312 for limiting.

[0076] like Figure 13 As shown, the inner sleeve F31 and the outer sleeve F32 are rotatably configured. Under the premise of rotation, the structure of the inner sleeve F31 remains stable. The output end extends out of the outer sleeve F32 and forms an external gear F311, which is used to mesh with the rack F33 for transmission. All inner sleeves F31 engage with the rack F33 on one side through the external gear F311, thus achieving good structural transmission. The outer periphery of the gear inner sleeve F31 can be configured as a cylindrical structure to match and rotate with the outer sleeve F32. Specifically, the inner part is limited by a rectangular inner frame F312 that cooperates with the bamboo strip. The length and width of the rectangular inner frame F312 are roughly the same as the length and width of the bamboo strip, but slightly larger, so that it can be used for bamboo strips with slightly different sizes. The rectangular structure design with a width significantly greater than its thickness allows the rectangular inner frame F312 to restrict the rolling of the bamboo strip during flipping, thus allowing the bamboo strip to complete a 90-degree flip. When the bamboo strip is conveyed, it passes through the outer end of the rectangular inner frame F312. After the flipping is completed, it can be powered by subsequent equipment for continued conveying and processing.

[0077] As an improved specific implementation, the input end of the inner sleeve F31 of the gear extends out of the outer sleeve F32 and forms a flared mouth F313 that facilitates the input of bamboo strips.

[0078] like Figure 13 As shown, the flared mouth F313 is a structure with a larger input end and a smaller output end, which allows the bamboo strips to be smoothly guided into the rectangular inner frame F312 and well limited in the reduced space during conveying and flipping.

[0079] As an improved specific implementation, a second limiting mechanism F4 is also provided in front of the flipping device F3. The second limiting mechanism F4 includes a limiting cylinder F41, a connecting rod F42, and a limiting wheel F43. The limiting cylinder F41 is set on the frame F1. The number of limiting wheels F43 corresponds to the number of transport grooves F21. The limiting wheels F43 are rotatably set on the connecting rod F42. The end of the connecting rod F42 is connected to the limiting cylinder F41 and is driven by the limiting cylinder F41 to move up and down. The limiting wheel F43 is set above the gear inner sleeve F31 and the transport groove F21. When the limiting cylinder F41 drives the connecting rod F42 to move up and down, the height of the limiting wheel F43 is adjusted, thereby adjusting the distance between the limiting wheel F43 and the transport groove F21.

[0080] like Figure 12 , 13As shown, limiting cylinders F41 are respectively installed on both sides of the width. A connecting rod F42 is installed at the lower part of the cylinder shaft of the limiting cylinder F41. The connecting rod F42 is horizontally arranged and has multiple limiting wheels F43 spaced apart. Each limiting wheel F43 corresponds to a transport trough F21. When the transport trough F21 moves to the front of the flipping device F3, the limiting wheels F43 are located above the transport trough F21, thus serving to limit the bamboo strips. The user pre-adjusts the limiting cylinder F41 according to the thickness of the bamboo strip, so that the limiting wheel F43 stops at a suitable height, thereby effectively limiting the bamboo strip from above. When the bamboo strip is flipped, the limiting wheel F43 is pushed upward so as not to affect the flipping process. When the bamboo strip is conveyed forward, the limiting wheel F43 rolls in coordination, thereby improving the stability of the bamboo strip during operation and avoiding instability of the bamboo strip during transportation.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
