[0020] 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.

[0021] Please refer to Figures 1 to 4 A cross-cutting machine with convenient blade replacement includes a beam 1, a lifting block 2, an isolation plate 3, a cutting knife 4, a card plate 5, a stud 6, a bearing plate 7 and a blowing plate 8. The lifting block 2 is arranged at both ends of the beam 1, the isolation plate 3 is arranged inside the beam 1, and there are two isolation plates 3. The cutting knife 4 is arranged inside the beam 1, the card plate 5 is arranged above the cutting knife 4, the stud 6 is arranged through the inside of the beam 1, the bearing plate 7 is arranged at the bottom of the beam 1, and the blowing plates 8 are arranged on both sides of the bearing plate 7.

[0022] The lifting block 2 is installed by the crossbeam 1, which is convenient for connecting the cross-cutting machine body. The installation of the cutting knife 4 can be achieved through the isolation plate 3 inside the crossbeam 1. The three cutting knives 4 form a whole. When one of the cutting knives 4 is damaged, the damaged one can be disassembled and assembled, avoiding the overall replacement of the cutting knife 4 and saving resources. The upper end of the cutting knife 4 can be limited by the card plate 5 to ensure that the card plate 5 is in full contact with the cutting knife 4 during installation. The stud 6 passes through the cutting knife 4, and the cutting knife 4 can be re-positioned, so that the stability of the cutting knife 4 is enhanced during installation and will not be displaced during operation, thereby improving the cutting quality of the device. The lower end of the cutting knife 4 can be limited by the load-bearing plate 7, further enhancing the installation stability of the cutting knife 4. Finally, the blowing plate 8 is installed on both sides of the load-bearing plate 7. When the cutting knife 4 is working, waste chips on the surface of the cutting object or objects that hinder cutting can be blown away, so that the cutting place remains clean.

[0023] like Figure 1 As shown, a groove matching the cutting knife 4 is added to the top of the load-bearing plate 7, and positioning bolts 9 in contact with the cutting knife 4 are threaded through both sides of the outer wall of the load-bearing plate 7, and a cutting knife 14 is provided at the bottom of the load-bearing plate 7.

[0024] The bottom of the cutting knife 4 can be positioned by the groove on the top of the bearing plate 7, ensuring the working stability of the cutting knife 4. At the same time, the cutting knife 14 at the bottom of the bearing plate 7 can complete the cutting of the object without any gaps.

[0025] like Figure 1 As shown, an L-shaped vent is provided inside the blowing plate 8, and an air duct 13 matching the vent is threadedly mounted on one side of the blowing plate 8.

[0026] The air duct 13 is installed through the blowing plate 8, and the air duct 13 can be used to remove the waste on the surface of the cut object or the processing that hinders the cut object, so that the cut area can be kept clean.

[0027] like Figure 3 and Figure 4 As shown, there are multiple cutting knives 4, which are fitted with the isolation plate 3. The inside of the cutting knife 4 is symmetrically provided with through holes 10 that match the studs 6, and both ends of the studs 6 are threadedly installed with screw caps that contact the beam 1.

[0028] The cutting knife 4 is installed inside the beam 1 through the isolation plate 3, and then the stud 6 is passed through the through hole 10 inside the cutting knife 4, and the stud 6 is passed through the beam 1 at the same time. When the stud 6 is threadedly locked with the screw nut, the stable installation of each cutting knife 4 can be achieved, ensuring its stability during operation.

[0029] like Figure 3 As shown, three groups of working grooves 11 are opened at equal intervals on the top of the crossbeam 1 , and each group of the working grooves 11 is provided with two working grooves. A rotating rod 15 that passes through the clamping plate 5 is rotatably installed on the inner wall of the working groove 11 .

[0030] The rotating rod 15 is installed through the working groove 11 on the top of the beam 1. The rotating rod 15 drives the clamping plate 5 to rotate during operation, so that the clamping plate 5 contacts the cutting blade 4, ensuring the stability of the top end of the cutting blade 4.

[0031] like Figure 2 and Figure 4 As shown, a dust shielding plate 12 is mounted on the top of the crossbeam 1 , and the dust shielding plate 12 is in contact with the isolation plate 3 .

[0032] The dust shielding plate 12 is installed through the crossbeam 1. The dust shielding plate 12 can cover the installation area of ​​the cutting knife 4 inside the crossbeam 1 to prevent dust from entering during daily work.

[0033] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
