DETAILED DESCRIPTION

[0022] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , 2, 3, and 4 show a specific embodiment of the high-precision trimming device for wood and bamboo boards of the present invention. This embodiment includes a feeding mechanism 1, a positioning mechanism 2, a conveying mechanism 3, and a trimming mechanism 4. The feeding mechanism 1 includes a placement table 11, a material suction cup 12, and a track 13. The positioning mechanism 2 includes a clamping roller 21 and two groups of positioning members 22. The conveying mechanism 3 includes a conveyor belt 31. The placement table 11 is provided with a conveying roller 14 along the conveying direction for the material to slide. The track 13 is erected above the placement table 11 and the conveyor belt 31. The material suction cup 12 is slidably arranged on the track 13 to move the position between the placement table 11 and the conveyor belt 31. The material suction cup 12 is controlled by a driving member to rise and fall, and then absorbs the material at the placement table 11, and places it after moving to the conveyor belt 31; the two groups 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 a driving member to approach and move away from the positioning member 22 on the other side, and then on one side. When the positioning piece 22 on one side approaches the positioning piece 22 on the other side, the material on the conveyor belt 31 is pushed to the positioning piece 22 on the other side; the clamping rolling wheels 21 are multiple groups and are arranged at intervals above the conveyor belt 31. The clamping rolling wheels 21 are controlled to rise and fall by the driving member, and then after they are lowered to contact the materials, they are positioned and cooperate with the conveyor belt 31 to transport the materials; the trimming mechanism 4 includes two pairs of circular saw blades 41, and 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 first pair of circular saw blades 41 is greater than the spacing between the second pair of circular saw blades 41, and then when the conveyor belt 31 transports the materials through the two pairs of circular saw blades 41, the first pair of circular saw blades 41 trim the outer edges of the materials, and the second pair of circular saw blades 41 accurately trim the materials.

[0024] When the present invention is used, Figure 1-4As shown, the material is a large-format wood and bamboo board with a rectangular cross-section. 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 a plurality of placement tables 11 are arranged 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. The material suction cup 12 is connected to an external air source and sucks the large-format wood and bamboo board when it descends and contacts the large-format wood and bamboo board. After sucking the large-format wood and bamboo board, the material suction cup 12 rises, 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; 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. 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 is 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, completing 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 edge cutting. 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 fix the width and trims the edges. The circular saw blade 41 that cuts later further trims the board accurately. 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 for large-format wood and bamboo boards provided by the present invention improves the equipment structure in many aspects, thereby achieving many beneficial effects: first, increasing the upper limit of the width and length of the wood and bamboo boards that can be trimmed; second, using multiple sets of mechanical structures and driving parts 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, improving the trimming quality and processing efficiency of the boards, and can be applicable to the processing of boards of different sizes.

[0025] As an improved specific implementation method, the positioning mechanism 2 also includes a transverse transmission roller 23 arranged on the side of the conveyor belt 31. The transverse transmission roller 23 is raised and lowered by a driving member. When the material suction cup 12 places the material and the two groups of positioning members 22 move to adjust the material position, the transverse transmission roller 23 rises to be higher than the conveyor belt 31, supports the material and rolls when the material moves.

[0026] like Figure 1 , 2 As shown in Figure 3, the transverse transmission roller 23 is driven by a cylinder to rise and fall. 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. 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 move and push the large-format wood and bamboo board to the positioning piece 22 on the other side. The lower transverse transmission roller 23 cooperates with rolling to improve the smoothness 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. The setting and use of the transverse transmission roller 23 make the adjustment and positioning of the large-format wood and bamboo board smoother and reduce the wear on the lower surface of the large-format wood and bamboo board.

[0027] As an improved specific implementation method, the positioning member 22 on one side is a movable rod 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 controlled by a cylinder to be raised and lowered, and the telescopic rod limits the material when rising and does not contact the material after descending.

[0028] like Figure 3 As 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.

[0029] As an improved specific implementation, the conveyor belt 31 is a crawler-type metal conveyor belt, on which an anti-skid metal block 32 is provided; the surface of the anti-skid metal block 32 is arranged with protrusions that increase friction.

[0030] like Figure 1 , 2 As shown in , 3, and 4, 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. 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.

[0031] As an improved specific implementation, a longitudinal transmission 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, and the longitudinal transmission roller 33 and the conveyor belt 31 jointly support the material. The longitudinal transmission rollers 33 are multiple groups and are arranged at intervals along the conveying direction of the conveyor belt 31, and the movable positioning member 22 on one side is provided between adjacent longitudinal transmission rollers 33.

[0032] like Figure 1 , 2 As 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.

[0033] As an improved specific implementation manner, the distance difference between the single-sided circular saw blades 41 of the two pairs of circular saw blades 41 is 10 mm, and the distance between the two pairs of circular saw blades 41 can be adjusted by an adjustment mechanism.

[0034] like Figure 4As shown, 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 10 mm offset on the same side. On the basis of completing the front and rear trimming of a single side, the chips can be broken up more fully during precise trimming, and the chips can be collected more promptly.

[0035] As an improved specific implementation, the trimming mechanism 4 further includes a dust suction mechanism 42 , which is disposed above the two pairs of circular saw blades 41 to suck away the chips.

[0036] like Figure 1 As shown, 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 certain width and trims the edge. 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 and successively taken away by the dust suction mechanism 42, which can ensure the cleanliness of the site. The dust suction mechanism 42 can be realized by existing technology, and its arrangement range covers two pairs of circular saw blades 41 to effectively suck and collect the chips.

[0037] 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 .

[0038] like Figure 2 , 4 As shown, 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, and 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 blade 41 and ensuring accurate edge cutting.

[0039] 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.
