Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bamboo material processing, especially to a wood and bamboo board edge cutting mechanism. BACKGROUND

[0002] In the traditional wood and bamboo board edge cutting process, the wood and bamboo board needs to be manually lifted onto a material table and then sent to the edge cutting device through a roller and spring pressing method. During the edge cutting process, the wood and bamboo board may shake and deviate due to uneven stress, which may result in uneven sides of the entire wood and bamboo board, low processing precision, large splicing gap, and greatly affect the subsequent application of the board. In addition, single cutting during edge cutting cannot guarantee the edge cutting precision, and the cutting pressure on the saw blade is large. SUMMARY

[0003] The utility model aims at overcoming the defects of the prior art, providing a wood and bamboo board edge cutting mechanism that stably positions the wood and bamboo board and improves the edge cutting precision through secondary side edges.

[0004] The utility model adopts the following technical scheme: a wood and bamboo board edge cutting mechanism includes a positioning mechanism, a conveying mechanism, and an edge cutting mechanism. The positioning mechanism includes a plurality of sets of compression rolling wheels. The conveying mechanism includes a conveyor belt. The plurality of sets of compression rolling wheels are arranged above the conveyor belt at intervals. The compression rolling wheels are controlled to rise and fall by a driving member, thereby positioning the material and conveying the material in cooperation with the conveyor belt when the material is lowered to contact the material. The edge cutting mechanism includes two pairs of circular saw blades. The two pairs of circular saw blades are arranged at intervals at the front and rear positions on both sides of the conveyor belt. The distance between the circular saw blades of the first pair of circular saw blades is greater than the distance between the circular saw blades of the second pair of circular saw blades. When the material is conveyed by the conveyor belt and passes through the two pairs of circular saw blades, the first pair of circular saw blades trim the edges of the material to a certain width, and the second pair of circular saw blades accurately cut the edges of the material.

[0005] As an improvement, the distance difference between the single circular saw blades of the two pairs of circular saw blades is 5-15 mm.

[0006] As an improvement, the distance between the two pairs of circular saw blades can be adjusted by an adjusting mechanism.

[0007] As an improvement, the edge cutting mechanism further includes a dust collection mechanism arranged above the two pairs of circular saw blades to suck away the cutting chips.

[0008] As an improvement, the compression rolling wheels are arranged in front, middle, and rear of the two pairs of circular saw blades.

[0009] As an improvement, the conveyor belt is a tracked metal conveyor belt, and anti-slip metal blocks are arranged on the tracked metal conveyor belt.

[0010] As an improvement, the surface of the anti-slip metal blocks is arranged with protrusions to increase friction.

[0011] The beneficial effects of this utility model are: the positioning mechanism enables effective positioning of wood and bamboo boards, improving the stability of edge trimming; and the two pairs of circular saw blades are used for secondary edge trimming, improving the accuracy of edge trimming.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 , 2 Figure 3 shows a specific embodiment of the wood and bamboo board trimming mechanism of this utility model. This embodiment includes a positioning mechanism 2, a conveying mechanism 3, and a trimming mechanism 4. The positioning mechanism 2 includes several sets of pressing rollers 21. The conveying mechanism 3 includes a conveyor belt 31. The several sets of pressing rollers 21 are spaced above the conveyor belt 31. The pressing rollers 21 are controlled to rise and fall by a drive component, thereby positioning the material when they descend and contact it, and cooperating with the conveyor belt 31 to convey the material. The trimming mechanism 4 includes two pairs of circular saw blades 41. The two pairs of circular saw blades 41 are arranged at intervals on both sides of the conveyor belt 31, and the distance between the front pair of circular saw blades 41 is greater than the distance between the rear pair of circular saw blades 41. Thus, when the conveyor belt 31 conveys the material past the two pairs of circular saw blades 41, the front pair of circular saw blades 41 trims the outer edge of the material to a fixed width, and the rear pair of circular saw blades 41 precisely trims the edge of the material.

[0018] In use, the wood and bamboo boards are transported from the feeding mechanism 1 to the inlet of the conveying mechanism 3. After the wood and bamboo boards are accurately positioned, the pressing rollers 21 above the conveyor belt 31 are driven by a cylinder to descend and press onto the wood and bamboo boards, completing the positioning of the boards. The pressing rollers 21 are spaced apart above the conveyor belt 31 to continuously press and position the wood and bamboo boards from above along the entire conveying direction of the conveyor belt 31, and to ensure stability during the subsequent edge trimming at the trimming mechanism 4. The conveyor belt 31 is driven by a motor, and the pressing rollers 21 cooperate to roll, fixing and transporting the wood and bamboo boards forward, keeping them stable so that they do not shift during subsequent edge trimming. When the wood and bamboo boards reach the trimming mechanism 4, they are trimmed. The first saw blade 41 cuts the outer edge of the board to a fixed width for trimming, and the second saw blade 41 further trims the edge precisely. Throughout the trimming process, the wood and bamboo boards are well limited by the pressing rollers 21, ensuring accurate and stable trimming. The driving components of each part in this utility model can be flexibly driven by cylinders, oil cylinders, motors, etc., which improves the degree of mechanization and automation and facilitates automatic control and management.

[0019] As an improved specific implementation, the distance difference between the single-sided circular saw blades 41 of the two pairs of circular saw blades 41 is 5-15mm. The spacing between the two pairs of circular saw blades 41 can be adjusted by an adjustment mechanism.

[0020] like Figure 3 As shown, the two pairs of circular saw blades 41 are spaced apart to meet the trimming requirements of different processing widths of the board and to more accurately match the amount of trimming, making the circular saw blades 41 trim more precisely, breaking down the chips more thoroughly, and ensuring that the chips are effectively sucked away and collected, thus ensuring a clean site. The circular saw blades 41, preferably 10mm, are installed with a 5-15mm offset on the same side. This allows for more thorough chip breaking and more timely chip removal during precise trimming, building upon the completion of single-sided front and rear trimming.

[0021] As an improved specific implementation, the trimming mechanism 4 also includes a dust collection mechanism 42, which is disposed above the two pairs of circular saw blades 41 to remove the chips.

[0022] like Figure 2 As shown, the wood and bamboo boards are trimmed at the trimming mechanism 4. The first circular saw blade 41 cuts the outer edge of the board to a fixed width, and the second circular saw blade 41 further trims the edge precisely. Because the processing is staggered at certain intervals, all the chips are broken up and successively removed by the dust collection mechanism 42, ensuring a clean work area. The dust collection mechanism 42 can be implemented using existing technology, and its arrangement covers both pairs of circular saw blades 41, effectively collecting and removing chips.

[0023] As an improved embodiment, the pressing and rolling wheels 21 are arranged in front of, in the middle of and behind the two pairs of circular saw blades 41.

[0024] As shown in Figure 1 , 3 , when the wood and bamboo board is conveyed to the position of the pressing and rolling wheels 21, the pressing and rolling wheels 21 are driven to descend by the air cylinder to press and position the wood and bamboo board, and the wood and bamboo board is pressed and positioned in front of, in the middle of and behind the two pairs of circular saw blades 41, so that the wood and bamboo board is stable during the edge cutting by the circular saw blades 41, and the edge cutting is accurate.

[0025] As an improved embodiment, the conveying belt 31 is a caterpillar metal conveying belt, and the caterpillar metal conveying belt is provided with anti-skid metal blocks 32. The surfaces of the anti-skid metal blocks 32 are arranged with protrusions for increasing friction.

[0026] As shown in Figure 1 , 2 , 3, the caterpillar conveying belt is used to convey the large-format wood and bamboo board. Compared with the traditional steel driving roller, the large-format wood and bamboo board is fixed on the surface of the conveying belt 31 by the anti-skid metal blocks 32, and the roughness of the anti-skid metal blocks 32 prevents the large-format wood and bamboo board from deviating during the conveying and edge cutting, improves the edge cutting accuracy of the board, and improves the yield. The anti-skid metal blocks 32 are arranged at intervals on the caterpillar metal conveying belt, the protrusions on the anti-skid metal blocks 32 can be specifically arranged in the shape of an array or an orderly arrangement such as a needle thorn and a groove, and after the lower surface of the large-format wood and bamboo board is placed thereon, the placement state of the structure can be effectively ensured, and the situation of slipping or deviation does not occur.

[0027] The preferred embodiments of the utility model are described above, the protection scope of the utility model is not limited to the above-mentioned embodiments, and any technical solution belonging to the idea of the utility model belongs to the protection scope of the utility model. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model are also regarded as the protection scope of the utility model.
