DETAILED DESCRIPTION

[0020] The following is a specific implementation of the present invention and combined with the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figure 1-5As shown, a specific embodiment of the automatic bundling and fixed-length cutting device for bamboo composite material of the present invention is shown. It comprises a front conveying mechanism 1, a bundling mechanism 0, a middle conveying mechanism 2, a cutting mechanism 4 and a rear conveying mechanism 5 arranged in sequence. The front conveying mechanism 1 comprises a front frame 11, a front transmission roller 12 and a pressing roller 13. The front transmission roller 12 is arranged on the front frame 11 for placing and conveying materials. The pressing roller 13 is arranged above the front transmission roller 12. The pressing roller 13 is controlled by a driving member to rise and fall, and then the material is positioned after it is lowered and hits the material. When the material is conveyed, the front transmission roller 12 and the pressing roller 13 are moved upward and downward by the driving member. 3 is rotated; the middle conveying mechanism 2 includes a middle frame 21, a middle transmission roller 22 and a conveying mechanism 3, the middle transmission roller 22 is arranged on the middle frame 21 to place and convey the material, the conveying mechanism 3 includes a material table 31, a support roller 32 and a clamping cylinder 33, the support roller 32 is two groups and is arranged in front and behind the material table 31 to place the material, the material table 31 is controlled by a driving member to move along the conveying direction of the middle frame 21, the clamping cylinder 33 is two groups and is arranged between the two groups of support rollers 32, the clamping cylinder 33 is arranged on both sides and clamps the material in the middle when extended; when the material is clamped and the material table 31 moves forward along the middle frame 21, the material is conveyed forward, and when the material is not clamped and the material table 31 is not clamped, the material table 31 is not clamped. The material table 31 is reset when moving backward along the middle frame 21; the cutting mechanism 4 includes a mounting frame 41, a circular saw blade 42 and a control module, the circular saw blade 42 is arranged on the mounting frame 41 and can reciprocate laterally, and the circular saw blade 42 cuts the material at the mounting frame 41 when performing transverse reciprocating motion, and the rear conveying mechanism 5 includes a rear frame 51 and a plurality of rear drive rollers 52, and the plurality of rear drive rollers 52 are arranged at intervals on the rear frame 51 for placing and conveying the material; the control module detects the conveying distance of the material through a sensor, and stops the conveying mechanism 3 when conveying the first rated distance and controls the circular saw blade 42 to start cutting, and stops the conveying mechanism 3 when conveying the second rated distance and controls the bundling mechanism 0 to start bundling.

[0022] When the present invention is in use, the prepared large-format bamboo integrated material blank is placed at the front conveying mechanism 1 for input, and the ends of the bamboo integrated material blank are bundled by the bundling mechanism 0 subsequent to the front conveying mechanism 1. The large-format bamboo integrated material blank has a width of 0.3m-1.5m and a length of 1.5m-20m. The wire used for bundling is generally a synthetic fiber rope, such as nylon rope, polyester rope, and polypropylene rope. The clamping cylinder 33 in the conveying mechanism 3 performs stable clamping when the bamboo integrated material blank needs to be conveyed, and then the material table 31 is transferred forward a certain first rated distance, which can be preferably 60cm, 70cm, or 80cm. After the control module collects the first rated distance (60cm, 70cm, or 80cm) transferred forward through the sensor, it controls the bundling mechanism 0 to bundle the bamboo integrated material blank once, and repeats this process to complete the fixed-length bundling of bamboo integrated material blanks of a specific length, so that the bamboo integrated material blank forms multiple stable bundles at equal distances along the length direction, thereby ensuring the structural stability of large-sized bamboo integrated material blanks and completing the automatic conveying process of the slabs. According to different product requirements, the fixed-length cutoff length of the slab is set, and the fixed-length cutoff length of the slab is the second rated distance. For example, the fixed-length cutoff length of the slab is set to 500cm, and the front bundling position and the rear bundling position are set corresponding to the fixed-length cutoff length of the slab, and the values ​​of the front bundling position and the rear bundling position from the fixed-length cutoff position of the slab are set to 20cm; taking the first rated distance of 60cm as an example, the control module stops the conveying mechanism 3 every 60cm and bundles the bamboo integrated material blanks. When 480cm (front bundling position) is conveyed, bundling is performed before the fixed-length cutoff position of the slab, and bundling is performed again at 520cm (rear bundling position) when it is conveyed; in this way, the front and rear bamboo integrated material blank positions to be cut off are well stabilized, and when the position runs to the cutting mechanism 4, the conveying is stopped, that is, the second rated distance is run, and the large-size bamboo integrated material blanks are cut off by the circular saw blade 42. The slabs cut to a fixed length continue to be fed forward for output. Through the operation and processing of the above equipment, large-size bamboo composite material of a fixed length can be obtained according to different needs.

[0023] In terms of equipment implementation, the strapping mechanism 0 can be implemented using existing mature strapping equipment. Figure 1 , 4, 5 are introduced to the bundling mechanism 0, which includes a coil drum 01, a transmission gear 02, a winding rod 03 and a knotting mechanism 04, wherein the knotting mechanism 04 includes a pressing block 041, a first knotting claw 042, a second knotting claw 043 and a cutter 044; the bundling mechanism 0 has a conveying hole for conveying the bamboo composite material, the transmission gear 02 is rotatably arranged on the outer periphery of the conveying hole, the coil drum 01 and the winding rod 03 are arranged on the transmission gear 02 at intervals, and the knotting mechanism 04 is installed below the front frame 11, corresponding to the position below the conveying hole; the bundling mechanism 0 has a plurality of holes, wherein the plurality of holes are provided with ... The used wire is stored in the coil drum 01, and is pulled out to be wound around the winding rod 03, and is clamped at the pressing block 041 which can move forward and backward. The transmission gear 02 is rotated by an external driving member. When bundling is performed, the transmission gear 02 rotates to drive the coil drum 01 and the winding rod 03 to rotate, and the bundling wire is tied several times on the bamboo composite material blank. Then the first knotting claw 042 and the second knotting claw 043 extend to clamp the front and rear ends of the bundling wire to complete the knotting. The cutter 044 extends to cut the bundling wire, and the pressing block 041 presses the end of the bundling wire at the cut position again.

[0024] The front conveying mechanism 1 provides support for the conveying of the bamboo composite material and stability during bundling. The bamboo composite material is supported and rolled by the front transmission roller 12 during conveyance, and the clamping roller 13 is pressed on the upper part of the bamboo composite material from above, and cooperates with the lower front transmission roller 12 to form a good structural stability and improve the bundling stability; the clamping roller 13 can be controlled by a cylinder or an oil cylinder to rise and fall.

[0025] The middle conveying mechanism 2 provides support and conveying power for the conveying of bamboo composite material blanks. The bamboo composite material blanks are supported and rolled by the middle transmission rollers 22 during conveying. When the bamboo composite material blanks need to be conveyed forward or the structure is stable, the clamping cylinders 33 on the conveying mechanism 3 clamp the blanks from both sides to stabilize the blank structure, thereby ensuring that the bundling at the bundling mechanism 0 and the cutting at the cutting mechanism 4 can be carried out stably and accurately. When the material platform 31 is clamped and positioned, it can move forward to drive the bamboo composite material forward. The support rollers 32 on the material platform 31 provide good support for the bamboo composite material. When the clamping cylinder 33 clamps the bamboo composite material for moving transportation, the bamboo composite material is supported and moved by the support rollers 32. For the bamboo composite material with large specifications and heavy weight, the stability of movement can be improved, and the load of the driving part and the load between the parts can be reduced during movement. The control module cooperates with the sensor to detect the moving distance of the material platform 31 or the bamboo composite material, and the stop after reaching the rated distance can be controlled accordingly, and the bundling and cutting can be performed. The material platform 31 itself is provided with front and rear support rollers 32 to support the bamboo composite material, and the front and rear forces are uniform and stable, and it is reset when the bamboo composite material is not clamped. When the material platform 31 is reset, the support rollers 32 roll on the lower surface of the bamboo composite material, reducing the friction between the structures and making the reset smooth.

[0026] The cutting mechanism 4 is provided with a circular saw blade 42 which reciprocates perpendicularly to the conveying direction of the bamboo composite material blank, and performs a transverse cutting movement when starting to work, so as to transversely cut the bamboo composite material blank of a fixed length.

[0027] The rear transmission roller 52 of the rear conveying mechanism 5 continuously supports and transmits the cut large-size bamboo composite material backwards, and can be connected to the subsequent mechanism to allow the material to enter the next process.

[0028] The driving parts of each component in the present invention can be flexibly driven by using a cylinder, an oil cylinder, a motor, etc. as a power source, thereby improving the degree of mechanization and automation and facilitating automatic control management.

When the clamping cylinders 33 on both sides are extended, the four push pieces 34 clamp the material in the middle.

[0030] like Figure 1 , 3 As shown, the clamping cylinders 33 are specifically provided with no less than four. To control the cost and realize the function of stable clamping, it is preferred to have two clamping cylinders 33 on each side, so that the bamboo composite material blank in the middle can be stably clamped when the clamping cylinders 33 are synchronously extended. In addition, a push piece 34 is provided at the front end of the cylinder shaft of the clamping cylinder 33, and the surface area of ​​the push piece 34 is more stably pressed against the side of the bamboo composite material blank, thereby improving the clamping stability.

[0031] As an improved specific implementation method, the material table 31 is slidably arranged on the middle frame 21 through guide rails 311 on both sides; a rack and pinion assembly 312 is arranged in the middle of the material table 31 and the middle frame 21 along the conveying direction to cooperate with the driving member for transmission.

[0032] like Figure 1 , 2 As shown, the guide rails 311 on both sides improve the stability of the material platform 31 sliding on the middle frame 21, and the rack and pinion assembly 312 in the middle is connected to the external motor for transmission, so as to flexibly control the start and stop of the motor, carry out fixed-length conveying of the bamboo composite material blanks, and complete bundling and cutting.

[0033] As an improved specific implementation manner, the front transmission roller 12, the pressing roller 13, the support roller 32, the middle transmission roller 22, and the rear transmission roller 52 are arranged in sequence along the conveying direction of the material.

[0034] like Figure 1As shown, each part of the roller body forms a structural support in the conveying direction of the entire bamboo integrated timber blank to improve the stability and smoothness of the bamboo integrated timber blank; the clamping roller 13 and the support roller 32 (clamping structure) are closer to the bundling mechanism 0, which can stabilize the structure of the bamboo integrated timber blank when it is bundled; and when the support roller 32 (clamping structure) moves to the cutting mechanism 4, it can stabilize the structure of the bamboo integrated timber blank when it is cut.

[0035] As an improved specific implementation manner, the driving member of the pressing rolling wheel 13 is a pneumatic cylinder or an oil cylinder.

[0036] like Figure 1 As shown, when the air cylinder or the oil cylinder is specifically selected, the user can flexibly adjust the pressure of the air cylinder or the oil cylinder, and then adjust the pressure of the pressing rolling wheel 13 when it is pressed on the surface of the bamboo integrated timber blank, to ensure that the bamboo integrated timber blank is conveyed smoothly and without damaging the bamboo integrated timber blank while maintaining the stability of the bamboo integrated timber blank structure.

[0037] As an improved specific implementation, a sliding track 44 is transversely arranged on the mounting frame 41 , and the circular saw blade 42 is slidably arranged on the sliding track 44 through a sliding frame 45 , and the sliding frame 45 is controlled by a driving member to reciprocate along the sliding track 44 .

[0038] like Figure 1 , 2 As shown, the sliding track 44 is arranged on the upper part of the mounting frame 41, and the sliding frame 45 is set on the sliding track 44 for horizontal sliding. The circular saw blade 42 extends to the bottom of the mounting frame 41. The sliding frame 45 moves horizontally under the control of a specific driving member such as a motor or a cylinder, and the started circular saw blade 42 performs horizontal cutting of the bamboo composite material.

[0039] As an improved specific implementation manner, the driving member for driving the circular saw blade 42 is a motor 46 installed on the sliding frame 45 .

[0040] like Figure 1 , 2 As shown, the driving member for driving the circular saw blade 42 is specifically set as a motor 46, which can flexibly and accurately control the start and stop, and it is set on the sliding frame 45 and can move horizontally synchronously with the circular saw blade 42, thereby ensuring driving stability and reducing the complexity of the transmission structure.

[0041] As an improved specific implementation manner, a collecting groove 43 is provided on the mounting frame 41 below the circular saw blade 42 .

[0042] like Figure 1 , 2 As shown, the wood chips dropped when the bamboo composite material blank is cut can be collected in an orderly manner by the collecting trough 43, and the wood chips can be discharged from one side of the collecting trough 43 for processing, thereby ensuring a clean production environment.
