[0036] A cutting motor for driving the rotating shaft 32 to rotate is provided on one of the vertical bars 31. The staff places the quartz stone plate on the placement column 12 of the workbench 1, so that the edge of the quartz stone plate can be in a suspended state. According to the production specifications, the positions of the multiple first sliders 22 are adjusted so that the four second slide rails 231 can move accordingly. The four second slide rails 231 are rectangular in shape, and each end of the second slide rail 231 extends a distance. By adjusting the second slider 23, the corresponding end of the second slide rail 231 can contact the adjacent second slide rail 231 in turn, thereby ensuring that the saw blade 321 can completely cut the edge of the quartz stone plate; then, the horizontal plate 2 is moved toward the adjacent second slide rail 231 through the first hydraulic rod 111. The quartz stone plate moves in the direction of rotation, so that the saw blade 321 arranged on the mounting plate 3 can be located at the outer edge of the quartz stone plate. Subsequently, by adjusting the four fourth sliders 52, the four fourth sliders 52 move synchronously in the same direction, so that the mounting plate 3 arranged on the fourth slider 52 can move. According to the moving direction of the fourth slider 52, the position of the vertical plate 33 is adjusted, so that the vertical plate 33 facing the moving direction can be arranged in a horizontal state to avoid volume collision with the quartz stone plate. As the mounting plate 3 moves, the rotating shaft 32 arranged on the mounting plate 3 rotates, so that the multiple saw blades 321 arranged on the rotating shaft 32 can synchronously perform multi-segment cutting on the four edges of the quartz stone plate, which can not only improve The cutting speed can also reduce the risk of cracking at the edge of the quartz stone plate; during the cutting process, the positions of the two corresponding moving plates 41 are adjusted so that the two moving plates 41 are close to each other. As the two moving plates 41 are close to each other, the two sides of the quartz stone plate in the thickness direction are clamped to ensure the stability of the quartz stone plate during the cutting process, avoid shaking of the cut quartz stone plate, and ensure the integrity of the quartz stone plate; and through the cutting plate 51 set in the rectangular through groove 421, the triangular cutting part 511 on the cutting plate 51 can be moved in a direction perpendicular to the extension plate 42, and the triangular cutting parts 511 located on both sides of the quartz stone plate can cooperate with each other, so that the cut quartz stone plate is cut twice , and during the cutting process, the cutting plate 51 can move accordingly along the length direction of the rectangular through groove 421, so that the triangular cutting portion 511 can move along with the movement of the saw blade 321, so that the position of the triangular cutting portion 511 can be consistent, ensuring that the cut strip quartz stone slab can be gradually cut off and dropped onto the workbench 1 through the vertical through groove 331 on the vertical plate 33, thereby avoiding its length being too long and causing excessive vibration amplitude; when the cutting is completed, the first hydraulic rod 111 is loosened, the staff removes the quartz stone slab, and through the alternating movement of the two vertical plates 33 located on the same mounting plate 3, the saw blade 321 can continue to cut the quartz stone slab without resetting, thereby improving the cutting efficiency.

[0037] See also Figures 4 to 9 As shown, the cutting mechanism 5 also includes a fourth slider 52, a driving shaft 53 and a sector gear 54; each rectangular through slot 421 is provided with a strip slide 422 on both sides of the inner wall along the length direction, and a fourth slider 52 is slidably arranged in each strip slide 422, and a vertical block 521 is provided on the fourth slider 52, and a vertical slot 522 is provided on the vertical block 521, and both sides of the cutting plate 51 are slidably arranged in the corresponding vertical slot 522, and a return spring 523 is provided on the side of each fourth slider 52 close to the movable plate 41; each extension plate 42 is provided with two rotating plates 423, and the two rotating plates 423 are located on both sides of the corresponding rectangular through slot 421, and the driving shaft 53 is rotatably arranged on the two rotating plates 4 23, the outer wall of the driving shaft 53 is mirror-imaged with two slots 531, a circular hole 541 is arranged at the center of the sector gear 54, the driving shaft 53 is slidably arranged in the circular hole 541, and a block 542 is mirror-imaged on the inner wall of the circular hole 541, and the block 542 can be slidably arranged in the corresponding slot 531; an elliptical through groove 512 for accommodating a snap ring is arranged on the cutting plate 51, and a plurality of first gear teeth 513 are equidistantly arranged on the inner walls on both sides of the elliptical through groove 512 along the length direction, and the sector gear 54 is meshed with the corresponding first gear teeth 513; two limiting bars 514 for limiting the sector gear 54 are also arranged on both sides of each cutting plate 51, and the driving shaft 53 is located between the corresponding two limiting bars 514.

[0038] A driving motor for rotating the driving shaft 53 is provided on each rotating plate 423 close to one side of the moving plate 41. The driving motor drives the driving shaft 53 to rotate. As the driving shaft 53 rotates, the block 542 cooperates with the slot 531 to rotate the sector gear 54. The first gear teeth 513 on the inner walls on both sides of the elliptical through slot 512 enable the cutting plate 51 to move back and forth in the vertical direction. The setting of the limiting strip 514 can limit the sector gear 54 to prevent it from falling off from the elliptical through slot 512. At this time, the triangular cutting parts 511 on both sides of the quartz stone plate can cut the strip quartz stone plate into two The cutting plate 51 is then moved to a position away from the quartz stone strip, and the fourth slider 52 on both sides of the cutting plate 51 is able to overcome the elastic force of the corresponding reset spring 523 and move along the length direction of the rectangular through groove 421, thereby ensuring that the triangular cutting portion 511 can continue to cut the quartz stone strip at the initial position, ensuring the continuity of the cutting by the saw blade 321; as the cutting plate 51 moves, the cutting plate 51 moves away from the quartz stone strip, and under the elastic force of the reset spring 523, the cutting plate 51 can move away from the corresponding movable plate 41, thereby resetting, which is convenient for the subsequent secondary cutting of the quartz stone strip.

[0040] By providing two second hydraulic rods 43, the position of the movable plate 41 is adjusted by the second hydraulic rods 43, so that the cut strip quartz stone plate can be fixed during the cutting process, avoiding the strip quartz stone plate from shaking, and ensuring the stability during the cutting process.

[0041] See also Figure 7 As shown, an auxiliary roller 424 for assisting the movement of the quartz stone plate is further provided at one end of each extension plate 42 away from the corresponding moving plate 41 .

[0042] In order to facilitate the movement of the quartz stone plate, auxiliary rollers 424 are provided. The auxiliary rollers 424 located on the extension plates 42 on both sides of the quartz stone plate can contact the quartz stone plate, thereby reducing the friction between the extension plates 42 and the quartz stone plate and ensuring the stability of the movement of the quartz stone plate.

[0043] See also Figure 5 and Figure 7 As shown, each mounting plate 3 is further provided with an articulated seat 34 at both ends along the length direction, and an articulated shaft 332 is provided on both sides of the end of each vertical plate 33.

[0045] See also Figure 3 and Figure 6 As shown, a reciprocating screw rod 232 is rotatably provided in the second slide rail 231 , a reciprocating hole 241 is provided at the center of each third sliding block 24 , and the reciprocating screw rod 232 is threadedly connected with the corresponding reciprocating hole 241 .

The reciprocating motor drives the reciprocating screw 232 to rotate, and the third slider 24 can move back and forth along the length direction of the corresponding second slide rail 231 as the reciprocating screw 232 rotates, so that the saw blade 321 can cut the quartz stone slab back and forth.

[0047] See also Figure 3 and Figure 4 As shown, a square column 25 is provided at the bottom center of the horizontal plate 2, and two mounting grooves 251 are staggered on the square column 25.
