[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] This utility model provides two technical solutions:

[0029] The lifting assembly 2 is arranged inside the base 1;

[0030] The multi-wire cutting assembly 3 is arranged inside the lifting assembly 2. The multi-wire cutting assembly 3 includes two protruding shafts 31 distributed left and right. A plurality of winding wheels 35 are equidistantly and slidably mounted on the surface of the protruding shafts 31. Annular grooves 37 are formed at both ends of the winding wheels 35. Annular blocks 38 are rotatably mounted inside the two annular grooves 37. The opposite ends of the two annular blocks 38 extend outward. A bracket 39 is fixedly connected between the downwardly facing outer surfaces of the two annular blocks 38. A first lever 310 is mounted on the outer surface of the bracket 39.

[0031] There are two spacing adjustment components 4, both of which can be raised and lowered and symmetrically distributed on the left and right sides of the multi-line cutting component 3. The spacing adjustment component 4 includes an adjustment plate 41. The surface of the adjustment plate 41 is provided with a plurality of adjustment slots 42 that cooperate with the first levers 310. The angle between the long axes of each two adjacent adjustment slots 42 is the same. By adjusting the height of the adjustment plate 41, the first levers 310 can be slid inside the adjustment slots 42 to adjust the relative spacing between the first levers 310. When the adjustment plate 41 is raised or lowered, the first levers 310 slide in their adjustment slots 42, allowing the winding wheel 35 to move smoothly and accurately on the convex shaft 31 to adjust the relative spacing;

[0032] The height adjustment component 5 is provided on the lifting component 2 and is used to drive the spacing adjustment component 4 to perform lifting motion.

[0033] The lifting assembly 2 includes a hydraulic cylinder 21 installed on the top of the frame 11. The telescopic end of the hydraulic cylinder 21 slides through the top of the frame 11 and extends downward. The telescopic end of the hydraulic cylinder 21 is fixedly installed with a lifting plate 22, and a U-shaped frame 23 is symmetrically fixedly installed at the bottom of the lifting plate 22. Through the operation of the hydraulic cylinder 21, the telescopic end of the hydraulic cylinder 21 can drive the lifting plate 22 and the multi-wire cutting assembly 3 and the spacing adjustment assembly 4 installed thereon to descend as a whole.

[0034] Both ends of the two convex shafts 31 are fixedly connected to a rotating shaft 32, and the rotating shaft 32 is movable through the inner wall of the U-shaped frame 23 and extends outward, wherein a synchronous pulley group 33 consisting of a synchronous wheel and a synchronous belt is provided between the two ends, and the synchronous pulley group 33 can make the two convex shafts 31 rotate synchronously. The multi-wire cutting assembly 3 also includes a motor 34 fixedly mounted on the outer wall of one of the U-shaped frames 23, and the output end of the motor 34 is fixedly connected to one of the rotating shafts 32. A cutting wire 36 is wound between the surfaces of the two winding wheels 35 on each left and right side, and the bracket 39 is slidably arranged at the bottom of the U-shaped frame 23 through a slider and a slide rail. The motor 34 drives the convex shaft 31 to rotate, driving the cutting wire 36 on the winding wheel 35 to move at high speed for cutting. The winding wheel 35 can slide on the convex shaft 31, and the spacing is adjusted by the spacing adjustment assembly 4 to adapt to different product thickness requirements.

[0035] A lifting plate 43 is installed on the top of the adjustment plate 41 . An oblique groove 44 is provided on the outer surface of the lifting plate 43 . The lifting plate 43 is slidably arranged on the outer surface of the lifting plate 22 through a slider and a slide rail.

[0036] Figure 1-Figure 5 The second embodiment is shown, and its main difference from the first embodiment is that the height adjustment assembly 5 includes a cylinder 51 installed on the top of the lifting plate 22, and a translation frame 52 that can move back and forth is installed at the telescopic end of the cylinder 51. The middle part of the translation frame 52 is hollowed out to avoid interference between the translation frame 52 and the hydraulic cylinder 21 when moving. The translation frame 52 is installed on the top of the lifting plate 22 through slide rails and sliders. Second levers 53 that cooperate with the inclined slots 44 are installed on both sides of the translation frame 52. The cylinder 51 is telescopic to move the translation frame 52, and the second lever 53 slides in the inclined slots 44 to drive the adjustment plate 41 to move up and down, thereby linking the spacing adjustment assembly 4. It is easy to operate and can adjust the spacing of the cutting lines 36. The height adjustment assembly 5 can control the spacing adjustment assemblies 4 on both sides to perform lifting and lowering movements by only one cylinder 51. On the one hand, the spacing adjustment assemblies 4 on both sides can be lifted and lowered synchronously, which improves the adjustment accuracy. On the other hand, it saves power sources, reduces equipment costs, and reduces energy consumption.

[0037] A cutting platform 6 is installed near the middle of the top of the base 1. The cutting platform 6 is mainly composed of components such as a slide rail, a slider, a cutting table, a servo motor and a screw rod, all of which are existing mature technologies. They are installed on the cutting table with a special clamp, and the workpiece to be cut is clamped on the clamp. The screw rod is driven to rotate by the servo motor, and the workpiece to be cut can be moved back and forth along the length direction of the cutting line 36, and the cutting operation of the workpiece to be cut is realized in cooperation with the cutting mechanism.

[0038] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0039] Before performing multi-line cutting operations, first start the cylinder 51 in the height adjustment assembly 5 according to the thickness requirements of the product to be cut. The telescopic end of the cylinder 51 drives the translation frame 52 to move back and forth, and the second levers 53 on both sides of the translation frame 52 slide in the inclined groove 44 of the lifting plate 43, so that the lifting plate 43 drives the adjustment plate 41 to move up and down. As the height of the adjustment plate 41 changes, the first lever 310 slides in the adjustment groove 42, thereby driving the bracket 39 and the winding wheel 35 to slide on the convex shaft 31, so as to adjust the relative spacing of each winding wheel 35, thereby accurately setting the spacing between the cutting lines 36 to adapt to the cutting thickness requirements of the product. This process can quickly and flexibly adjust the cutting thickness on the same equipment, greatly improving the versatility and production efficiency of the equipment.

[0040] Next, start the motor 34, which drives the rotating shaft 32 connected to it to rotate, and the two cam shafts 31 rotate synchronously through the synchronous pulley set 33, and the cutting line 36 wound on the winding wheel 35 moves accordingly. At the same time, the hydraulic cylinder 21 of the lifting assembly 2 works, and the telescopic end of the hydraulic cylinder 21 drives the lifting plate 22 and the multi-wire cutting assembly 3 and the spacing adjustment assembly 4 installed thereon to descend as a whole, so that the cutting line 36 contacts the material to be cut placed on the cutting platform 6 and starts the cutting operation.
