Description

Technical Field

[0001] This invention relates to the field of bamboo strip splicing equipment technology, specifically to an automatic bamboo strip arrangement and splicing equipment. Background Technology

[0002] After bamboo is cut, it undergoes processes such as node trimming, strip splitting, double-sided planing, steaming, drying, and sorting. Multiple glued bamboo strips are then joined together to form a board, which is then hot-pressed to create the final product. In existing technology, the process of joining and gluing multiple bamboo strips into a board is usually done manually, followed by shaping through pressure and heating. This method has the following technical drawbacks:

[0003] Inefficient: Manual assembly requires placing, aligning and gluing each piece individually, which is time-consuming and labor-intensive;

[0004] Unstable quality: Manual operation can easily lead to uneven bamboo strip arrangement and uneven gluing pressure, which can cause warping or cracking of the boards after splicing (i.e., bamboo strips break due to excessive compression).

[0005] While existing inventions can automatically assemble bamboo strips, they involve applying glue horizontally, flipping individual bamboo strips vertically, and then clamping them horizontally to glue multiple vertical strips together. This method makes it difficult to guarantee the quality of the assembled board due to the vertically positioned bamboo strips. Therefore, there is an urgent need for a device that can automatically arrange bamboo strips and achieve high-quality assembly. Summary of the Invention

[0030] Due to the adoption of the above technical solutions, the technical progress achieved by this invention is as follows.

[0031] This invention, through its modular mechanical structure design, solves the problems of high reliance on manual labor and large quality fluctuations in traditional bamboo strip splicing, providing reliable technical support for the industrial production of bamboo boards. Specific advantages are as follows:

[0032] This invention enables full-process automation and continuous production:

[0033] By coordinating the alternating feeding of bamboo strips through dual multi-row feeding troughs and the pull-out mechanism, unmanned continuous operation from bamboo strip feeding and gluing to splicing is achieved. The alternating feeding of bamboo strips through dual multi-row feeding troughs at the feeding end, combined with the alternating receiving of bamboo strips through dual multi-row discharging troughs at the discharging end, allows the equipment to switch troughs without stopping, improving production efficiency. The clamps of the pull-out mechanism move synchronously with the gluing machine to pull out the bamboo strips, ensuring that the bamboo strips fall precisely into the discharging trough, avoiding the misalignment problems of traditional manual splicing.

[0034] The feeding U-shaped trough and the discharging U-shaped trough enable continuous operation of feeding, gluing and discharging of a vertical row of bamboo strips.

[0035] This invention enables precise alignment and deformation prevention control:

[0036] The alignment mechanism ensures precise alignment of bamboo strips through the mechanical cooperation of a fixed baffle and a reciprocating baffle, combined with the stable guidance of a telescopic guide rod.

[0037] The pressing mechanism uses a pressing plate with through holes and a guide wheel to work together. During the pressing process, the pressing guide rod ensures vertical movement, eliminates the bending and deformation of the bamboo strip, and effectively ensures the straightness of the bamboo strip.

[0038] The gear drive between the coating roller and the scooping roller enables them to rotate in opposite directions, which not only achieves uniform coating but also prevents glue from dripping, thus effectively ensuring the thickness of the glue layer.

[0039] This invention enables flexible production adaptation capabilities:

[0040] The first lifting drive cylinder adjusts the lifting of the upper traction roller, and the second lifting drive cylinder controls the lifting of the glue coating roller. This not only meets the requirements for traction and glue coating of bamboo strips of different thicknesses, but also automatically avoids the last layer of bamboo strips when applying glue, thus meeting the process requirements of multi-layer splicing.

[0055] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0056] An automatic bamboo strip arranging and splicing device, combined with Figure 1As shown, the system includes a feeding base 1, a gluing machine 6, and a discharging base 7 arranged sequentially from left to right. A feeding trolley 2 is mounted on the feeding base 1, moving back and forth along it. The feeding trolley 2 has two multi-row feeding troughs 22, which work alternately as the trolley moves. Both troughs are used to horizontally stack bamboo strips from bottom to top. The feeding base 1 also includes an aligning mechanism 3, a pressing mechanism 4, and a pushing mechanism 5. The aligning mechanism 3 aligns the bamboo strips in the multi-row feeding troughs 22; the pressing mechanism 4 presses down on the bamboo strips in the troughs 22 to flatten them; and the pushing mechanism 5 pushes the bottom layer of bamboo strips from the bottom of the multi-row feeding troughs 22 into the gluing machine 6. The gluing machine 6 applies glue to the upper surface of the bamboo strips. A discharge trolley 8 is installed on the discharge base 7. The discharge trolley 8 moves back and forth along the discharge base 7. The discharge trolley 8 is equipped with two multi-row discharge troughs 82. The two multi-row discharge troughs 82 work alternately as the feeding trolley 2 moves. Both multi-row discharge troughs 82 are used to horizontally stack glued bamboo strips from bottom to top to achieve the arrangement and splicing of boards. The top height of the two multi-row discharge troughs 82 is higher than the bottom height of the two multi-row feeding troughs 22, so as to ensure that each layer of bamboo strips after glue application in the multi-row feeding trough 22 falls into the multi-row discharge trough 82 one by one, thereby completing the arrangement and splicing of boards. The equipment also includes a pull-out mechanism 9, which is horizontally supported above the multi-row discharge troughs 82 and is set opposite to the discharge end of the glue coating machine 6. The pull-out mechanism 9 is used to clamp the end of the bamboo strips coming out of the glue coating machine 6 and move synchronously with the discharge of the glue coating machine 6 to pull out the bamboo strips, so that the bamboo strips fall downward into the multi-row discharge troughs 82.

[0057] like Figure 2 As shown, the bottom of the feeding trolley 2 is provided with two parallel feeding electric guide rails 21, which are arranged on the feeding base 1 along the front-back direction. The multi-row feeding trough 22 includes a number of feeding slots 222 formed by multiple rows of equally spaced feeding uprights 221. Each feeding slot 222 is arranged along the left-right direction of the feeding base 1, and the width of each feeding slot 222 is adapted to the width of the bamboo strip. The length of each feeding slot 222 is shorter than the length of the bamboo strip, which facilitates the alignment and pushing of the bamboo strips.

[0058] The bottom of the discharge trolley 8 is provided with two parallel discharge electric guide rails 81, which are arranged on the discharge base 7 along the front-back direction. The multi-row discharge trough 82 includes a number of discharge slots 822 formed by multiple rows of equally spaced discharge uprights 821. Each discharge slot 822 is arranged along the left-right direction of the discharge base 7, and the width of each discharge slot 822 is adapted to the width of the bamboo strip. The length of each discharge slot 822 is shorter than the length of the bamboo strip.

[0059] like Figure 3 As shown, the alignment mechanism 3 includes two sets of multi-row feeding troughs 22 arranged on the front and rear sides of the feeding base 1, which work alternately. The alignment mechanism 3 includes a fixed baffle 31 erected on the feeding base 1 and located on the right side of the feeding trolley 2, and an alignment drive cylinder 32 horizontally arranged on the feeding base 1 and located on the left side of the feeding trolley 2. The telescopic rod of the alignment drive cylinder 32 is arranged to the right and connected to a reciprocating baffle 33 opposite to the fixed baffle 31. The reciprocating baffle 33 pushes the bamboo strips to the right under the drive of the alignment drive cylinder 32, thereby cooperating with the fixed baffle 31 to align the bamboo strips. A horizontally arranged telescopic guide rod 34 is provided between the side of the reciprocating baffle 33 away from the bamboo strips and the feeding base 1. The telescopic guide rod 34 can guide the reciprocating motion of the reciprocating baffle 33, thereby achieving smooth pushing of the bamboo strips.

[0060] The pressing mechanism 4 includes a spanning frame 41 straddling the feeding trolley 2 along the bamboo strip feeding direction and located between two sets of alignment mechanisms 3, with the spanning frame 41 facing the feeding side of the glue applicator 6. A pressing drive cylinder 42 is mounted on the spanning frame 41. The telescopic rod of the pressing drive cylinder 42 is positioned downwards and connected to a pressing plate 43. The pressing plate 43 is horizontally positioned above the multi-row feeding troughs 22. Driven by the pressing drive cylinder 42, the pressing plate 43 can travel to the bottom of the multi-row feeding troughs 22. Through holes 431 are provided on the pressing plate 43 at positions corresponding to the feeding uprights 221 on the multi-row feeding troughs 22. The through holes 431 allow the feeding uprights 221 to pass through, thereby enabling the pressing plate 43 to press down on the bamboo strips under the drive of the pressing drive cylinder 42. Several sets of guide wheel pairs 44 are also provided on the span frame 41. Each guide wheel pair 44 includes two guide wheels arranged opposite to each other. A pressure strip guide rod 45 is erected on the upper surface of the pressure plate 43 at a position opposite to each guide wheel pair 44. The pressure strip guide rod 45 passes through the corresponding guide wheel pair 44 and is slidably assembled with the two guide wheels of the corresponding guide wheel pair 44, thereby realizing the guidance of the pressing process and ensuring the smooth pressing of the bamboo strip.

[0061] The pushing mechanism 5 includes a push plate drive cylinder 51 located at the left end of the feeding base 1 and between the two sets of alignment mechanisms 3, with the push plate drive cylinder 51 positioned opposite to the feeding side of the glue coating machine 6. The telescopic rod of the push plate drive cylinder 51 is positioned to the right and connected to a push plate 52. The push plate 52 is slidably assembled with the feeding base 1. The push plate 52 is used to abut against the left end of the bottom layer of bamboo strips in the multi-row feeding trough 22 under the drive of the push plate drive cylinder 51, thereby pushing the bottom layer of bamboo strips in the multi-row feeding trough 22 into the glue coating machine 6.

[0062] like Figures 4 to 6As shown, the glue applicator 6 includes a U-shaped housing 61. The housing 61 is equipped with a traction mechanism 62, a glue applicator 63, and a transmission drive mechanism 64. The traction mechanism 62 is used to continue to pull the bamboo strip to the right after the bamboo strip is pushed in by the pusher mechanism 5. The glue applicator 63 is located on the right side of the traction mechanism 62 and is used to apply glue to the upper surface of the bamboo strip. The transmission drive mechanism 64 is connected to the traction mechanism 62 and the glue applicator 63 and is used to drive the traction mechanism 62 and the glue applicator 63 to move.

[0063] The traction mechanism 62 includes a lower traction roller 621, which is horizontally arranged along the front-rear direction of the housing 61 and rotatably connected to the housing 61 at both ends. Two first lifting plates 623 are arranged on the inner surface of the housing 61, which are opposite each other along the front-rear direction. The two first lifting plates 623 are located directly above the two ends of the lower traction roller 621 and are longitudinally slidably assembled with the housing 61. An upper traction roller 624 is rotatably assembled between the two first lifting plates 623, located directly above the lower traction roller 621 and parallel to it. A first lifting drive cylinder 622 is connected to the top of each first lifting plate 623. The first lifting drive cylinder 622 is longitudinally arranged on the inner surface of the housing 61 and is used to drive the first lifting plate 623 to slide longitudinally, thereby adjusting the distance between the upper traction roller 624 and the lower traction roller 621, thus adapting to the traction of bamboo strips of different thicknesses.

[0064] The gluing mechanism 63 includes a support roller 631, which is horizontally arranged along the front-rear direction of the housing 61 and rotatably connected to the housing 61 at both ends. The top surface of the support roller 631 is flush with the top surface of the lower traction roller 621. The support roller 631 is used to support the bamboo strip from the bottom. Two second lifting plates 633 are arranged inside the housing 61 in a front-rear direction. The two second lifting plates 633 are located directly above the two ends of the support roller 631 and are slidably mounted longitudinally to the housing 61. A gluing roller 634 is rotatably mounted between the two second lifting plates 633. The gluing roller 634 is located directly above the support roller 631 and is parallel to the support roller 631. The gluing roller 634 is used to apply glue to the upper surface of the bamboo strip that needs to be glued. Each of the second lifting plates 633 is connected to a second lifting drive cylinder 632 at its top. The second lifting drive cylinder 632 is longitudinally arranged at the top of the machine housing 61. The second lifting drive cylinder 632 is used to drive the second lifting plate 633 to slide longitudinally, thereby adjusting the distance between the glue coating roller 634 and the support roller 631, so as to adapt to the glue coating on the upper surface of bamboo strips of different thicknesses. At the same time, before the last layer of bamboo strips enters the glue coating mechanism 63, the second lifting drive cylinder 632 is used to raise the glue coating roller 634, thereby avoiding the glue coating operation on the upper surface of the last layer of bamboo strips.

[0065] A glue-collecting roller 635 is also arranged parallel to the left side of the coating roller 634. Both ends of the glue-collecting roller 635 are rotatably connected to two second lifting plates 633, respectively. The glue-collecting roller 635 is used to prevent excess glue from dripping. Specifically, the diameter of the glue-collecting roller 635 is smaller than the diameter of the coating roller 634, and the central axis of the glue-collecting roller 635 is on the same horizontal plane as the central axis of the coating roller 634, and the glue-collecting roller 635 is tangent to the coating roller 634. A waist-shaped hole 611 is longitudinally provided on the housing 61 to allow for the lifting and lowering of the coating roller 634 and the glue-collecting roller 635.

[0066] The transmission drive mechanism 64 includes a transmission drive motor 641 disposed on the bottom of an inner side of the housing 61. The rotating shaft of the transmission drive motor 641 passes through the housing 61 and is provided with a first transmission wheel 642.

When the drive motor 641 drives the first drive wheel 642 to rotate, the glue roller 634 and the idler roller 631 move in opposite directions and both move in the direction of bamboo strip output through the transmission of the first drive belt 646, the guide tension wheel 645, the second drive wheel 643 and the third drive wheel 644.

[0067] One end of the coating roller 634 is also provided with a first gear 647, which is located on the same side as the second transmission wheel 643, and one end of the scoop roller 635 is also provided with a second gear 648, which meshes with the first gear 647.

[0068] A fourth drive wheel 649 is provided at one end of the idler roller 631, and a fifth drive wheel 6410 is provided at the same end of the lower traction roller 621 on the same side as the fourth drive wheel 649. A second drive belt 6411 is fitted onto the fourth drive wheel 649 and the fifth drive wheel 6410. When the drive motor 641 is working, the idler roller 631 and the lower traction roller 621 move in the same direction as the bamboo strip output direction under the drive of the fourth drive wheel 649, the fifth drive wheel 6410 and the second drive belt 6411.

[0069] like Figures 7 to 10As shown, the pull-out mechanism 9 includes a support frame 91, on which two pull-out guide rails 92 are mounted. The two pull-out guide rails 92 are horizontally and parallel, and are arranged in the direction of bamboo strip output. A frame 93 is disposed between the two pull-out guide rails 92. Electric wheels 94 are slidably mounted on the front and rear ends of the frame 93, and are used to drive the frame 93 to reciprocate along the pull-out guide rails 92. A clamp 96 is mounted on the frame 93 to clamp the ends of each bamboo strip, thereby pulling the bamboo strip out as the frame 93 moves.

[0070] The clamp 96 includes a fixed shaft 961, which is perpendicular to the pull-out guide rail 92 and horizontally arranged, with both ends of the fixed shaft 961 fixedly connected to the machine frame 93. A movable shaft 964 is arranged on the side of the fixed shaft 961 away from the glue applicator 6, with both ends of the movable shaft 964 horizontally slidably assembled with the machine frame 93. The movable shaft 964 is parallel to the fixed shaft 961, and the central axis of the movable shaft 964 is on the same horizontal plane as the central axis of the fixed shaft 961. Several sets of grippers are arranged at intervals along the length direction on the fixed shaft 961 and the movable shaft 964, and the sets of grippers are arranged one-to-one with the bamboo strips at the discharge end of the glue applicator 6. Positioning sleeves 9610 are respectively sleeved on the fixed shaft 961 and the movable shaft 964 between adjacent grippers. The positioning sleeves 9610 are used to position the grippers, and a shaft cylinder 9611 that is assembled with the fixed shaft 961 and the movable shaft 964 is arranged on the outer side of the outermost gripper.

[0071] The gripper includes two lower chucks 962 that are rotatably mounted to the fixed shaft 961, an upper chuck 963 located between the tops of the two lower chucks 962 and rotatably mounted to the fixed shaft 961, two upper hinge plates 965 located on both sides of the top of the upper chuck 963 and rotatably mounted to the movable shaft 964, and a lower hinge plate 966 located between the bottoms of the two lower chucks 962 and rotatably mounted to the movable shaft 964.

[0072] A lower hinge shaft 967 passes through the bottom of each lower chuck 962 and the bottom of each lower hinge piece 966 away from the movable shaft 964. The lower hinge shaft 967 is used to hinge the lower chuck 962 and the lower hinge piece 966. An upper hinge shaft 968 passes through the top of each upper chuck 963 and the top of each upper hinge piece 965 away from the movable shaft 964. The upper hinge shaft 968 is used to hinge the upper chuck 963 and the upper hinge piece 965. The movable shaft 964 is also connected to a clamping drive cylinder 969 disposed on the machine frame 93. When the clamping drive cylinder 969 extends or retracts, it drives the movable shaft 964 to slide, thereby moving the movable shaft 964 closer to and away from the fixed shaft 961, thereby driving the jaws to move. When the extension rod of the clamping drive cylinder 969 extends, the jaws perform a clamping action; when the extension rod of the clamping drive cylinder 969 retracts, the jaws perform an opening action.

[0073] The bottom of the discharge base 7 is provided with a first adjusting leg 71, which is used to adjust the height of the discharge base 7, thereby realizing the height adjustment of the multi-discharge material trough 82. The bottom of the support frame 91 is provided with a second adjusting leg 95, which is used to adjust the height of the pull-out guide rail 92, thereby realizing the height adjustment of the clamp 96.

[0074] like Figure 11 As shown, to prevent the bamboo strips from bending upwards or downwards after gluing, thus preventing the pull-out mechanism 9 from effectively clamping them, the pull-out mechanism 9 is equipped with an anti-bending mechanism 10 located near the discharge end of the gluing machine 6. The anti-bending mechanism 10 is used to prevent the bamboo strips from bending vertically. Specifically, the anti-bending mechanism 10 is located on the side of the support frame 91 near the gluing machine 6, such as... Figure 12 As shown, the anti-bending mechanism 10 includes a planetary roller 101 and a mounting frame 102. The planetary roller 101 is adjustable up and down on the support frame 91 to accommodate bamboo strips of different thicknesses. The planetary roller 101 is used to prevent the bamboo strips from bending upwards. The planetary roller 101 is provided with star-shaped blades, which are serrated, needle-shaped, or blade-shaped, etc., in order to minimize the contact area with the bamboo strips so as not to affect the glue applied to the bamboo strips. The mounting frame 102 is set on the support frame 91 and is located on the side of the planetary roller 101 away from the glue applicator 6.

[0075] The mounting frame 102 is slidably fitted with translational side plates 103 on both sides. The translational side plates 103 move along the direction of bamboo strip movement. A support rod 104 and a connecting plate 105 are arranged between the translational side plates 103. The support rod 104 is used to support the bamboo strip from the bottom, thereby preventing the bamboo strip from bending downwards. The connecting plate 105 is located on the side of the support rod 104 near the planetary roller 101. The connecting plate 105 is connected to a guide plate 106 that is inclined downwards. The guide plate 106 is used to guide the bamboo strip before it enters the support rod 104, so as to prevent the bamboo strip from bending downwards and passing under the support rod 104. The translational side plates 103 are connected to a translational drive cylinder 107. The translational drive cylinder 107 is used to drive the translational side plates 103 to move, thereby realizing the translation of the support rod 104 and the guide plate 106, and adjusting them to a suitable position to prevent the bamboo strip from bending downwards.

[0076] The equipment also includes a controller, which is electrically connected to the feeding trolley 2, the aligning mechanism 3, the pressing mechanism 4, the pushing mechanism 5, the discharging trolley 8, the traction mechanism 62, the glue applicator 6, the glue applicator 63, the transmission drive mechanism 64, the pull-out mechanism 9, the clamp 96, and the anti-bending mechanism 10, respectively, to achieve coordinated operation. Specifically, the output end of the controller is connected to the controlled ends of the feeding electric guide rail 21, the discharging electric guide rail 81, the aligning drive cylinder 32, the pressing drive cylinder 42, the pushing plate drive cylinder 51, the first lifting drive cylinder 622, the second lifting drive cylinder 632, the transmission drive motor 641, the electric traveling wheel 94, the clamping drive cylinder 969, and the translation drive cylinder 107, respectively.

[0077] The working principle of this invention is as follows:

[0078] Material is alternately fed into the multi-row feeding trough 22. When a multi-row feeding trough 22 is full, the bamboo strips are aligned by the aligning mechanism 3 on the same side, and then driven to face the gluing machine 6. The bamboo strips are straightened by the pressing mechanism 4, and then the bottom bamboo strips are pushed into the gluing machine 6 from the bottom of the multi-row feeding trough 22 by the pushing mechanism 5. The bamboo strips entering the gluing machine 6 are pulled into the gluing mechanism 63 by the traction mechanism 62. The gluing mechanism 63 applies glue to the upper surface of the bamboo strips. The bamboo strips coming out of the gluing machine 6 are clamped by the clamp 96 under the action of the anti-bending mechanism 10. The clamp 96, driven by the electric walking wheel 94, cooperates with the traction mechanism 62 to pull out the bamboo strips. When the bamboo strips are finished... After the bamboo strips are coated with glue and pulled to the end point, clamp 96 releases the bamboo strips, and the bamboo strips fall into the multi-row feeding trough 82. When the last layer of bamboo strips in the multi-row feeding trough 22 enters the glue applicator 6, the glue applicator 63 has already been raised and will not apply glue to the upper surface of the last layer of bamboo strips. At the same time, the feeding trolley 2 drives another set of multi-row feeding troughs 22 filled with bamboo strips to face the glue applicator 6. After the last layer of bamboo strips falls into the multi-row feeding trough 82, the discharging trolley 8 drives another set of empty multi-row feeding troughs 82 to face the glue applicator 6 and continues the above operation. The bamboo strips that have been arranged and spliced ​​in the multi-row feeding trough 82 are taken out one by one by the robot arm and sent to the feeder in front of the press. The feeder feeds the bamboo strips into the press for compaction.

[0079] It is worth noting that this invention can also be used for applying glue to a row of upright bamboo strips, such as... Figure 1 As shown, a feeding U-shaped trough 11 is also provided between the alternating rows of feeding troughs 22; a discharging U-shaped trough 12 is also provided between the alternating rows of discharging troughs 82, and the discharging U-shaped trough 12 and the feeding U-shaped trough 11 are located on the same horizontal plane. Figure 13As shown, the upright row of bamboo strips is placed in the feeding U-shaped trough 11, with the initial upright row of bamboo strips protruding from the end of the feeding U-shaped trough 11 near the pushing mechanism 5; the pushing mechanism 5 pushes the upright row of bamboo strips into the glue applicator 6; the whole entering the glue applicator 6 is pulled into the glue applicator 63 by the traction mechanism 62, and the glue applicator 63 applies glue to the upper surface of the whole; the whole exiting the glue applicator 6 finally enters the discharge U-shaped trough 12, and the robot arm takes it out and sends it to the feeder in front of the press, and then feeds it into the press for compaction.
