[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 Figures 4 to 9 As shown, the cutting mechanism 5 further includes a fourth slider 52, a drive shaft 53 and a sector gear 54; strip-shaped chutes 422 are provided on the inner walls of both sides of each rectangular through groove 421 along the length direction, a fourth slider 52 is slidably arranged in each strip-shaped chute 422, a vertical block 521 is arranged on the fourth slider 52, a vertical groove 522 is arranged on the vertical block 521, both sides of the cutting plate 51 are slidably arranged in the corresponding vertical grooves 522, and a return spring 523 is arranged on one side of each fourth slider 52 close to the moving plate 41; two rotating plates 423 are arranged on each extension plate 42, the two rotating plates 423 are located on both sides of the corresponding rectangular through groove 421, the drive shaft 53 is rotatably arranged between the two rotating plates 423, two card slots 531 are arranged on the outer wall of the drive shaft 53 in a mirror image manner, a circular hole 541 is arranged at the center of the sector gear 54, the drive shaft 53 is slidably arranged in the circular hole 541, and card blocks 542 are arranged on the inner wall of the circular hole 541 in a mirror image manner, and the card blocks 542 are slidably arranged in the corresponding card slots 531; an oval through groove 512 for accommodating a snap ring is arranged on the cutting plate 51, a plurality of first round teeth 513 are arranged at equal intervals on the inner walls of both sides of the oval through groove 512 along the length direction, and the sector gear 54 meshes with the corresponding first round teeth 513; two limiting strips 514 for limiting the sector gear 54 are further arranged on both sides of each cutting plate 51, and the drive shaft 53 is located between the corresponding two limiting strips 514.

[0038] A drive motor for rotating the drive shaft 53 is arranged on each rotating plate 423 on one side close to the moving plate 41. The drive shaft 53 is driven to rotate by the drive motor. As the drive shaft 53 rotates, through the cooperation of the card blocks 542 and the card slots 531, the sector gear 54 can rotate. Through the first round teeth 513 on the inner walls of both sides of the oval through groove 512, the cutting plate 51 can move back and forth in the vertical direction. The arrangement of the limiting strips 514 can limit the sector gear 54 to prevent it from falling off from the oval through groove 512. At this time, the triangular cutting parts 511 on both sides of the quartz stone plate can perform secondary cutting on the cut strip-shaped quartz stone plate, and during the cutting process, the triangular cutting parts 511 can move along with the strip-shaped quartz stone plate, so that the fourth sliders 52 on both sides of the cutting plate 51 can overcome the elastic force of the corresponding return springs 523 and move along the length direction of the rectangular through groove 421, so as to ensure that the triangular cutting parts 511 can continue to cut the strip-shaped quartz stone plate at the initial position and ensure the continuity of the cutting of the saw blade 321; as the cutting plate 51 moves, the cutting plate 51 moves away from the strip-shaped quartz stone plate. Under the elastic force of the return spring 523, the cutting plate 51 can move away from the corresponding moving plate 41 to reset, which is convenient for subsequent secondary cutting of the quartz stone plate.

[0039] See Figure 3 and Figure 6 As shown, the stabilizing mechanism 4 further includes a second hydraulic rod 43; there are two second hydraulic rods 43, both of the two second hydraulic rods 43 are arranged on the corresponding vertical plate 33 and are located on the opposite sides of the corresponding two moving plates 41, and the actuator of the second hydraulic rod 43 is connected to the corresponding moving plate 41.

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

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

[0042] To facilitate the movement of the quartz stone plate, by providing the auxiliary rollers 424, the auxiliary rollers 424 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 plate 42 and the quartz stone plate and ensuring the stability of the movement of the quartz stone plate.

[0043] See Figure 5 and Figure 7 As shown, hinge seats 34 are further provided at both ends of each mounting plate 3 along the length direction, hinge shafts 332 are provided on both sides of the end of each vertical plate 33, the hinge shafts 332 are rotatably arranged in the corresponding hinge seats 34, a first double-shaft motor 35 is provided on one side of the mounting plate 3 along the length direction, first bevel gears 351 are provided at both ends of the first double-shaft motor 35, and second bevel gears 333 are provided at the ends of each hinge shaft 332 close to the first double-shaft motor 35, and the first bevel gears 351 are meshed with the corresponding second bevel gears 333.

[0044] By providing the first double-shaft motor 35 on the mounting plate 3, the first double-shaft motor 35 drives the first bevel gears 351 at both ends to rotate, and the first bevel gears 351 are meshed with the second bevel gears 333, so that the two vertical plates 33 can rotate alternately by 90° along the corresponding hinge shafts 332, enabling the saw blade 321 to perform reciprocating cutting and improving the cutting efficiency.

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

[0046] A reciprocating motor for driving the reciprocating lead screw 232 to rotate is further provided on each second slide rail 231. The reciprocating lead screw 232 is driven to rotate by the reciprocating motor. The third slider 24 can move back and forth along the length direction of the corresponding second slide rail 231 as the reciprocating lead screw 232 rotates, so that the saw blade 321 can reciprocate to cut the quartz stone plate.

[0047] See Figure 3 and Figure 4 As shown in the figure, a square column 25 is provided at the center of the bottom of the horizontal plate 2. Two mounting grooves 251 are staggeredly arranged on the square column 25. The two mounting grooves 251 are arranged in sequence along the length direction of the square column 25, and the length directions of the two mounting grooves 251 are perpendicular to each other.

The second lead screws 253 are threadedly connected to the corresponding first sliders 22. A compression spring 233 is arranged on one side of each second slider 23 away from the end of the second slide rail 231.

[0048] By alternately arranging the two second biaxial motors 252, the positions of the four first sliders 22 can be adjusted, so that quartz stone plates of different specifications can be produced. Under the elastic force of the compression spring 233, the end of the second slide rail 231 can always abut against the side of the adjacent second slide rail 231, so as to ensure that the saw blade 321 can completely cut the corners of the quartz stone plate.

[0049] See Figure 4 As shown in the figure, an elastic telescopic rod 254 extending vertically downward is provided at the bottom of the square column 25, and a pressing disc 255 is provided at the end of the elastic telescopic rod 254.

[0050] In order to further ensure the stability during the cutting process of the quartz stone plate, through the arranged elastic telescopic rod 254, with the arrangement of the first hydraulic rod 111, the pressing disc 255 can abut against the quartz stone plate, so as to fix the quartz stone plate and ensure the stability during the cutting process of the quartz stone plate.
