DETAILED DESCRIPTION

[0028] 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.

[0029] like Figure 1-4 The figure shows a specific embodiment of the high-precision edge trimming device and method for large-format wood and bamboo boards of the present invention.

[0030] The high-precision trimming method for large-format wood and bamboo panels includes the following steps:

[0031] [1] Board stacking: Stack large-format wood and bamboo boards and place them in the material stacking area;

[0032] [2] Board loading: Control the material suction cup 12 to suck up the large-format wood or bamboo boards in the material stacking area and place them on the conveyor belt 31;

[0033] [3] Plate positioning: The transverse transmission roller 23 on the side of the conveyor belt 31 is raised to support the large-format wood and bamboo plate, and then the positioning piece 22 on one side of the conveyor belt 31 is used to push the large-format wood and bamboo plate to align with the positioning piece 22 on the other side, and then the transverse transmission roller 23 and the positioning piece 22 on the other side are lowered under the large-format wood and bamboo plate, and the large-format wood and bamboo plate falls onto the conveyor belt 31;

[0034] [4] Board fixing and transportation: The pressing roller 21 above the conveyor belt 31 is lowered to contact the large-format wood and bamboo board, and the pressing roller 21 cooperates with the running conveyor belt 31 to transport the large-format wood and bamboo board forward;

[0035] [5] Board trimming: Two pairs of circular saw blades 41 are arranged at intervals on both sides of the conveyor belt 31. The spacing between the front pair of circular saw blades 41 is greater than the spacing between the rear pair of circular saw blades 41. When large-format wood or bamboo boards are transported through the two pairs of circular saw blades 41, the first sawing circular saw blade 41 cuts the outer edge of the board to a certain width and trims the edges, and the rear saw blade 41 further trims the board precisely.

[0036] [6] Post-processing of boards: After trimming, the large-format wood and bamboo boards are further processed by planers and sanders. The processed large-format wood and bamboo boards are then stacked and cured.

[0037] A high-precision trimming device for large-format wood and bamboo boards, comprising a feeding mechanism 1, a positioning mechanism 2, a conveying mechanism 3 and a trimming mechanism 4, wherein the feeding mechanism 1 comprises a placing table 11, a material suction cup 12 and a track 3, the positioning mechanism 2 comprises a pressing rolling wheel 21, a transverse transmission roller 23 and two sets of positioning members 22, the conveying mechanism 3 comprises a conveyor belt 31, the placing table 11 is used as a material stacking area, a conveying roller 14 is arranged on the placing table 11 along the conveying direction for the large-format wood and bamboo boards to slide, and the track 13 is provided with a conveying roller 14 for the large-format wood and bamboo boards to slide. The material suction cup 12 is arranged above the placing table 11 and the conveyor belt 31, and can be slidably arranged on the track 13 to move the position between the placing table 11 and the conveyor belt 31. The material suction cup 12 is controlled by the driving member to rise and fall, and then suck the large-format wood and bamboo board on the placing table 11, and place it after moving to the conveyor belt 31; two sets of positioning members 22 are respectively arranged on both sides of the conveyor belt 31, and the positioning member 22 on one side is controlled by the driving member to approach and move away from the positioning member 22 on the other side, so as to move the positioning member 22 on one side. When the positioning member 22 of one side is close to the positioning member 22 on the other side, the large-format wood and bamboo board on the conveyor belt 31 is pushed to the positioning member 22 on the other side; the transverse transmission roller 23 is controlled by the driving member to rise and fall, and when the material suction cup 12 places the large-format wood and bamboo board and the two groups of positioning members 22 adjust the position of the large-format wood and bamboo board, the transverse transmission roller 23 rises to be higher than the conveyor belt 31, supports the large-format wood and bamboo board and rolls when the large-format wood and bamboo board moves; the pressing rolling wheels 21 are multiple groups and are arranged at intervals on the conveyor belt. Above the conveyor belt 31, the pressing roller 21 is controlled to rise and fall by a driving member, and then after descending to contact the large-format wood and bamboo board, the large-format wood and bamboo board is positioned and the large-format wood and bamboo board is transported in cooperation with the conveyor belt 31; the trimming mechanism 4 includes a dust suction mechanism 42 and two pairs of circular saw blades 41, the two pairs of circular saw blades 41 are arranged at intervals at the front and rear positions on both sides of the conveyor belt 31, and the spacing between the front pair of circular saw blades 41 is greater than the spacing between the rear pair of circular saw blades 41, and the dust suction mechanism 42 is arranged above the two pairs of circular saw blades 41 to suck away the chips.

[0038] When the present invention is implemented, Figure 1-4As shown, the cross section of the large-format wood and bamboo board is rectangular. First, the large-format wood and bamboo board is placed on a placement table 11. There are a large number of conveying rollers 14 on the placement table 11, which are convenient for manually pushing the material to the bottom of the material suction cup 12; the feeding mechanism 1 arranges 4-6 groups of material suction cups 12 according to the length of the large-format wood and bamboo board to be processed, and multiple sections of placement tables 11 are set along the length of the large-format wood and bamboo board for placement and support. The material suction cup 12 is controlled by a cylinder to rise and fall, and the material suction cup 12 is connected to an external air source when it descends and contacts the large-format wood and bamboo board. The material suction cup 12 rises after sucking the large-format wood and bamboo board, and the material suction cup 12 is driven by a motor to move back and forth along the track 13, thereby transporting the large-format wood and bamboo board to the top of the conveyor belt 31; the transverse transmission roller 23 is driven by a cylinder to rise and fall, and when the large-format wood and bamboo board is transported to the top of the conveyor belt 31, the transverse transmission roller 23 is in an ascending state, and then when the large-format wood and bamboo board is lowered and placed, the transverse transmission roller 23 and the conveyor belt 31 cooperate to support the large-format wood and bamboo board. After the material suction cup 12 puts down the large-format wood and bamboo board, the positioning piece 22 on one side is driven by the cylinder to push the large-format wood and bamboo board to the positioning piece 22 on the other side, and the lower transverse transmission roller 23 cooperates to roll to improve the smoothness of the movement of the large-format wood and bamboo board. When the large-format wood and bamboo board is aligned with the positioning piece 22 on the other side, the position adjustment of the large-format wood and bamboo board is completed; then the positioning piece 22 and the transverse transmission roller 23 are reset, so that the large-format wood and bamboo board naturally falls on the conveyor belt 31, and then the upper pressing roller 21 is driven by the cylinder to press down on the large-format wood and bamboo board to complete the positioning of the large-format wood and bamboo board; the conveyor belt 31 is driven by a motor to run, and the upper pressing roller 21 cooperates to roll to fix and transport the large-format wood and bamboo board forward, keep the large-format wood and bamboo board stable, so that the large-format wood and bamboo board will not deviate during subsequent trimming. The large-format wood and bamboo board is trimmed when it reaches the trimming mechanism 4. The circular saw blade 41 that cuts first cuts the outer edge of the board to a fixed width and trims it. The circular saw blade 41 that cuts later further trims the board accurately. Since the processing is staggered at a certain interval, the chips cut off are all broken up and taken away by the dust collection mechanism 42 covering the two pairs of circular saw blades 41, which can ensure the cleanliness of the site. During the entire trimming process, the large-format wood and bamboo board is well limited by the pressing rolling wheel to ensure accurate and stable trimming. The large-format wood and bamboo board after trimming can be further processed by a planer and a sander to ensure the processing size and precision requirements of the board. The processed boards are stacked and cured. According to needs, the driving parts of each component in the present invention can be flexibly driven by cylinders, oil cylinders, motors, etc. as power sources to improve the degree of mechanization and automation, and facilitate automatic control management.The high-precision trimming device and method for large-format wood and bamboo boards provided by the present invention improve the production process and production equipment in many aspects, thereby achieving many beneficial effects: First, the upper limit of the width and length of the wood and bamboo boards that can be trimmed is increased; second, multiple sets of mechanical structures and driving parts are used to improve work efficiency, reduce the number of required staff, reduce labor intensity, improve the mechanization and automation level of high-precision trimming of large-format wood and bamboo boards, and reduce the labor intensity and danger of workers; third, the trimming quality and processing efficiency of the boards are improved, and it can be applicable to the processing of boards of different sizes.

[0039] As an improved specific implementation method, in step [1] of stacking the boards, the width of the large-format wood and bamboo boards is 0.3m-1.5m, and the length is 1.5m-20m.

[0040] like Figure 1 As shown, the feeding mechanism 1 is arranged with 4-6 groups of material suction cups 12 according to the length of the large-format wood and bamboo board being processed, and a plurality of placement tables 11 are arranged along the length of the large-format wood and bamboo board to adapt to the length and width of the large-format wood and bamboo board. The material suction cups 12 can be activated as needed to increase the upper limit of the width and length of the trimmable wood and bamboo board, thereby improving production efficiency and automation, and reducing the safety hazards of manual handling.

[0041] As an improved specific implementation method, in step [5], during the board trimming, the spacing between the two pairs of circular saw blades 41 is adjusted according to the width of the large-format wood or bamboo board, and the circular saw blades 41 on the same side are installed with a 10 mm offset.

[0042] In specific implementation, the two pairs of circular saw blades 41 adjust the spacing to meet the trimming requirements of the plates under different processing widths, and more accurately adapt the trimming amount, so that the circular saw blades 41 can trim more accurately, break up the chips more fully, and effectively collect the chips, ensuring a clean and tidy site. The circular saw blades 41 are installed with a 10mm offset on the same side, so that the chips can be broken up more fully during precise trimming, and the chips can be collected more promptly on the basis of completing the single-sided front and rear trimming.

[0043] As an improved specific implementation method, the positioning member 22 on one side is a movable rod that is controlled by a cylinder, and the movable rod moves closer to and away from the positioning member 22 on the other side; the positioning member 22 on the other side is a telescopic rod that is controlled by a cylinder to be raised and lowered, and the telescopic rod limits the large-format wood and bamboo board when rising, and does not contact the large-format wood and bamboo board after descending.

[0044] like Figure 2 , 3As shown, in a specific implementation, multiple groups of movable rods and telescopic rods are arranged at intervals along the conveying direction of the conveyor belt 31, and then when in use, the movable rod is synchronously displaced on one side of the large-format wood and bamboo board to perform a stable push, and the telescopic rod on the other side performs a stable resistance limit to ensure that the large-format wood and bamboo board is accurately positioned after adjustment; after the position adjustment and positioning of the large-format wood and bamboo board is completed, the movable rod is reset outward, the telescopic rod is lowered, and the horizontal transmission roller 23 below is also lowered, and then the large-format wood and bamboo board can fall onto the conveyor belt 31 in an adjusted position state, and then the clamping roller 21 arranged at intervals along the conveying direction of the conveyor belt 31 performs multi-position pressing and positioning, and the large-format wood and bamboo board can maintain a stable position state for subsequent conveying and trimming.

[0045] As an improved specific implementation manner, the conveyor belt 31 is a crawler-type metal conveyor belt, on which an anti-skid metal block 32 is provided, and the surface of the anti-skid metal block 32 is arranged with protrusions for increasing friction.

[0046] like Figure 2 , 3 As shown, a crawler conveyor belt is used to transport large-format wood and bamboo boards. Compared with the traditional steel transmission roller, since the large-format wood and bamboo boards are fixed to the surface of the conveyor belt 31 by anti-skid metal blocks 32, the roughness of the anti-skid metal blocks 32 prevents the large-format wood and bamboo boards from running off during transportation and trimming, thereby improving the trimming accuracy of the boards and the yield rate. The anti-skid metal blocks 32 are arranged at intervals on the crawler metal conveyor belt, and the protrusions on the anti-skid metal blocks 32 can be specifically arranged in a shape structure of needle spines, grooves, etc. in an array or orderly arrangement. After the lower surface of the large-format wood and bamboo board is placed on it, the placement state of the structure can be effectively guaranteed without slipping or deviation.

[0047] As an improved specific implementation method, a longitudinal drive roller 33 arranged in the same conveying direction as the conveyor belt 31 is further provided between the conveyor belt 31 and the placement table 11. The longitudinal drive roller 33 and the conveyor belt 31 jointly support the large-format wood and bamboo board. The longitudinal drive rollers 33 are multiple groups and are arranged at intervals along the conveying direction of the conveyor belt 31. A movable positioning member 22 on one side is arranged between adjacent longitudinal drive rollers 33.

[0048] like Figure 1 , 2As shown in Figure 3, when the large-format wood and bamboo board is transferred from the placement table 11 to the conveyor belt 31, the large-format wood and bamboo board is supported by the longitudinal transmission roller 33, and the transverse transmission roller 23 is preferably arranged between the longitudinal transmission roller 33 and the conveyor belt 31. When the large-format wood and bamboo board is raised, it is used to place the large-format wood and bamboo board in advance and adjust the position of the large-format wood and bamboo board with rolling. After the transverse transmission roller 23 is lowered, the large-format wood and bamboo board outside the range of the conveyor belt 31 is auxiliary supported and conveyed by the longitudinal transmission roller 33, so that the transverse transmission roller 33 and the conveyor belt 31 cooperate to adapt to the transportation and trimming of large-format wood and bamboo boards with wider specifications. The conveyor belt 31 does not have to be completely covered in the width direction. Relying on its effective width and cooperating with the upper clamping roller 21, the positioning and transportation of the large-format wood and bamboo board can be achieved. The large-format wood and bamboo board on the outside is handed over to the longitudinal transmission roller 33 for rolling support and transportation. Under the premise of ensuring the normal transportation of the large-format wood and bamboo board, the cost of the equipment can be effectively controlled. The movable positioning member 22 is adaptively arranged between adjacent longitudinal transmission rollers 33 so that the structures do not affect each other and are convenient for maintenance.

[0049] As an improved specific implementation manner, the pressing roller 21 is arranged at the front, middle and rear of the two pairs of circular saw blades 41 .

[0050] like Figure 2 , 3 As shown in 4, when the large-format wood and bamboo board is transported to the position of the pressing roller 21, the pressing roller 21 is driven down by the cylinder to press and position the large-format wood and bamboo board. The front, middle and rear of the two pairs of circular saw blades 41 all press and position the large-format wood and bamboo board, thereby ensuring the stability of the large-format wood and bamboo board during the edge cutting process of the circular saw blades 41 and ensuring accurate edge cutting.

[0051] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
