[0025] By adopting the above technical solution, the staff can adjust the relative height of the distance adjustment component 1 and the cutting knife 4 by cooperating with the screw rod 33 and the lifting cylinder 34 when necessary, so as to better meet the working needs in different situations.

[0026] Specifically, the outer shape of the connecting frame 31 is L-shaped, and one side of the lifting cylinder 34 and the inner side of the connecting frame 31 are in close contact with each other.

[0027] By adopting the above technical solution, the tool can limit and guide the movement of the lifting cylinder 34 through the connecting frame 31, thereby preventing the lifting cylinder 34 from rotating and deviating during the movement, ensuring the normal operation.

[0028] Specifically, the cleaning assembly 35 includes a fan 351, a nozzle 352 and an L-shaped box 353. The L-shaped box 353 is installed above the lifting cylinder 34 and on one side of the connecting frame 31. The fan 351 is installed on the side of the L-shaped box 353 close to the screw 33.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the tilt adjustment device 6 includes a connecting sleeve 61, a screw 62, a threaded hole 63 and a fixing ring 64, the connecting sleeve 61 is installed on the side of the connecting frame 31 close to the adjusting rod 7, the fixing ring 64 is installed on the outer side of one end of the adjusting rod 7 close to the connecting sleeve 61 and located on the inner side of the connecting sleeve 61, a plurality of threaded holes 63 are provided on the inner side of the fixing ring 64, and a screw 62 is installed on one side of the connecting sleeve 61 and located on the inner side of the fixing ring 64.

[0033] By adopting the above technical solution, the staff can adjust the inclination of the cutting knife 4 to a certain extent through the cooperation of the fixing ring 64 and the connecting sleeve 61 when necessary, so as to better meet the inclined cutting needs of different raw materials or special situations.

[0034] Specifically, the inner side of the connecting sleeve 61 and the outer side of the fixing ring 64 are in close contact with each other.

[0035] By adopting the above technical solution, the cutter can limit and guide the rotation of the connecting sleeve 61 through the fixing ring 64, thereby preventing the rotation of the connecting sleeve 61 from being offset, thereby ensuring the normal operation.

[0036] When this embodiment is used, when it is necessary to adjust the inclination of the cutting knife 4, the staff turns the screw 62 in the inclination adjustment device 6 to disengage it from the threaded hole 63 on the fixing ring 64, and then the staff pulls the connecting sleeve 61 to rotate it and the cutting knife 4 and other structures along the fixing ring 64 to the required inclination, and then rotates the screw 62 in the opposite direction to connect it with the corresponding threaded hole 63. The adjustment is completed, thereby better meeting the needs of inclined cutting of different raw materials or special situations.

[0037] In the utility model, the structures and principles of the distance adjustment component 1, the knob 2, the cutting knife 4, the second motor 5, the adjusting rod 7, and the clamping component 8 composed of the first fixed seat, the second fixed seat, the shock-absorbing pad, the clamping block, the adjusting screw and the second guide slider, which are composed of an adjusting seat, a first guide slider, a sliding rod, a bidirectional screw, a worm wheel, a worm and a first motor, have been disclosed in a kind of adjustable cutting tool for a slitting machine disclosed in Chinese patent application No. 202320258426.1. The working principle is that according to the required cutting width, the output shaft of the first motor drives the worm to rotate, and drives the bidirectional screw to rotate under the meshing connection between the worm and the worm wheel, and the adjusting rod and the worm wheel are meshed. The two-way lead screw threaded connection and the guiding action of the sliding rod can realize the adjustment of the moving width of the cutting knives on both sides of the adjustment seat, and the worm gear cannot reversely drive the worm to rotate, thereby realizing the stability of the two-way lead screw rotation and facilitating adjustment and use. The cutting knife is driven by the second motor to rotate and cut. After the position of the cutting knife is adjusted, the adjusting rotating knob drives the adjusting screw to rotate. Under the relationship of the threaded connection between the adjusting screw and the second fixed seat, the clamping block is driven to clamp and limit and fix. The set shock-absorbing pad can greatly reduce the vibration of the cutting knife on the adjusting rod, thereby realizing the stability of the cutting knife width adjustment, significantly improving work efficiency and facilitating use.

[0038] The working principle and use process of the utility model are as follows: when the slitting machine needs to use a cutter to cut the material, the staff operates the distance adjustment component 1 to drive the two adjusting rods 7 to move, thereby adjusting the distance between the two cutting knives 4, and then rotates the two knobs 2, thereby driving the two clamping components 8 to clamp and fix the two adjusting rods 7, and then respectively rotates the rotating plates 32 in the two lifting and cleaning devices 3, thereby respectively driving the two screw rods 33 to rotate, the screw rod 33 is threadedly connected to the connecting frame 31, the screw rod 33 is bearing-connected to the lifting cylinder 34, and one side of the lifting cylinder 34 is tightly attached to the connecting frame 31, so the two screw rods 33 respectively drive the two lifting cylinders 34 and the upper structure thereof to move, thereby adjusting the relative height between the two cutting knives 4 and the distance adjustment component 1, and then start the two lifting and cleaning devices. The second motor 5 drives the two cutting knives 4 to rotate, thereby cutting the passing materials, and the staff can start the fan 351 in the cleaning component 35, and the fan 351 sends air into the L-shaped box 353, and then the air is ejected from the nozzle 352, so as to blow away the debris and other materials on the surface of the cutting knife 4, and then perform the cleaning work; when it is necessary to adjust the inclination of the cutting knife 4, the staff twists the screw 62 in the inclination adjustment device 6 to disengage it from the threaded hole 63 on the fixing ring 64, and then the staff pulls the connecting sleeve 61 to rotate it and the cutting knife 4 and other structures along the fixing ring 64 to the required inclination, and then rotates the screw 62 in the opposite direction to connect it with the corresponding threaded hole 63, and the adjustment is completed, so as to better meet the needs of inclined cutting of different raw materials or special situations.
