The positioned board material is fed into the saw blade at a uniform speed through the feeding mechanism to be cut into the required sheet-shaped finished products, which can greatly improve the production efficiency. The multi-blade saw can improve the work efficiency of cutting strips. Generally, a high-speed sawing mode is adopted, and a wire saw or a circular saw can be used to cut the whole wood board into small boards of corresponding sizes.

After the two semicircular brackets 16 are in contact, the outer circle is in the shape of a full circle, which is convenient for the installation and fixation of the saw blade 26.

[0019] In the same sawing structure, an anti-rotation bracket 19 is installed on the side wall of one of the turntables 18, and an anti-rotation slot 20 is opened in the other turntable 18 for the anti-rotation bracket 19 to be inserted and prevent the two turntables 18 from rotating relative to each other. After the anti-rotation bracket 19 is inserted into the anti-rotation slot 20, the position between the two turntables 18 is locked and unnecessary rotation cannot occur, so that unnecessary deflection will not occur between the two semicircular brackets 16.

[0020] A mounting groove 23 is provided in the middle of one side wall where the two semicircular brackets 16 contact each other, and a mounting stud 24 is detachably connected between the two mounting grooves 23 at the same position. Second nuts 25 that can lock the mounting stud 24 in the mounting groove 23 are threadedly sleeved on both side walls thereof. The mounting stud 24 and the second nut 25 can lock the position between the two semicircular brackets 16.

[0021] The turntable 18 is symmetrically provided with fastening plates 22 that can be connected to the inner peripheral side walls of the semicircular bracket 16 . The fastening plates 22 can strengthen the connection strength between the turntable 18 and the semicircular bracket 16 .

[0022] A first top plate 2 is provided on the top surface of one side of the U-shaped chassis 1, and a second top plate 3 is provided on the top surface of the other side of the U-shaped chassis 1. A first slide rail 4 is installed on the top of the first top plate 2, and a second slide rail 6 is installed on the top of the second top plate 3. A first slide seat 5 is slidably provided on the first slide rail 4, and a first base 10 is detachably installed on the top of the first slide seat 5.

Both ends of the inner side wall of the arc-shaped protective cylinder 30 are connected with positioning studs 35 through connecting plates 34. The positioning studs 35 can slide longitudinally along the vertical groove 33. The part of the positioning studs 35 located outside the vertical groove 33 is threadedly sleeved with a third nut 36. When the positioning studs 35 slide to the bottom of the vertical groove 33, the outer circle of the arc-shaped protective cylinder 30 coincides with the outer circle of the semicircular chuck 29. When it is necessary to change the installation position of the single saw blade 26 on the rotating rod 13 and the sawing angle, the arc-shaped protective cylinder 30 can be removed from between the two semicircular chucks 29 through the lifting frame 31.

[0024] A locking plate 38 is detachably mounted on the bottom end of the semicircular chuck 29 located at the top of the second base 28. A sleeve 27 is sleeved on the end of the rotating rod 13 away from the driving member 12. A rotating column 39 is installed in the middle of the other end of the sleeve 27.

The lifting members 8 change the longitudinal distance between the bottom plate 9 and the saw blade 26, thereby facilitating the placement of plates of different thicknesses on the bottom plate 9 and also facilitating the sawing of grooves of different depths on the plates.

[0026] In the present invention, the rotating rod 13 rotates at a high speed to drive the multiple saw blades 26 to saw synchronously at a high speed, thereby sawing the whole plate into multiple small plates. In the actual sawing process, the installation position of the saw blade 26 on the rotating rod 13 can be adjusted by changing the position of the two semicircular clamping frames 16 in the middle guide groove 14 in the single sawing structure. At the same time, the installation angle of the saw blade 26 at any position of the rotating rod 13 can be adjusted by driving the semicircular clamping frame 16 to rotate in the middle guide groove 14, that is, the subsequent sawing angle can be adjusted. During the sliding and rotating process of the semicircular clamping frame 16 in the middle guide groove 14, the connecting stud 17 is in the side guide groove 14. The semicircular bracket 16 can slide and rotate synchronously in the groove 15, and finally the sliding position and the rotation angle of the connecting stud 17 in the side guide groove 15 can be locked only by rotating the first nut 21. The whole locking action structure is simple and efficient, thereby locking the sliding position and the rotation angle of the semicircular bracket 16 in the middle guide groove 14, and finally locking the installation position and the installation angle of the saw blade 26 on the rotating rod 13, so as to adjust the subsequent sawing position and the sawing angle, which is convenient for sawing small plates of different sizes and small plates of different sizes with a certain deflection angle on the edge in a single sawing process of the whole plate, enriching the sawing scenes of multiple blade saws.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
