The cutting knife structure comprises a knife holder 1 installed in the cutting device, and an assembly roller 2 is arranged in the knife holder 1. The two ends of the assembly roller 2 are coaxially fixedly connected with shafts 21, and the ends of the two shafts 21 away from each other are rotatably arranged on the side wall of the knife holder 1. A rotating mechanism 3 is arranged on the knife holder 1, and the rotating mechanism 3 is used to drive the shafts 21 and the assembly roller 2 to rotate. The structure of the rotating mechanism 3 is as follows. The rotating mechanism 3 comprises a motor 31 fixedly installed on one side of the knife holder 1, and the output shaft of the motor 31 is coaxially fixedly connected with a worm 32. One end of one of the shafts 21 extends to the outside of the knife holder 1 and is fixedly connected with a worm wheel 22. The worm 32 and the worm wheel 22 are engaged. When the motor 31 is started, the output shaft drives the worm 32 to rotate. Through the engagement transmission of the worm 32 and the worm wheel 22, the worm wheel 22 drives the shafts 21 and the assembly roller 2 to rotate. A plurality of cutters 4 are arranged in an annular array on the circumferential side wall of the assembly roller 2. When the assembly roller 2 rotates, the plurality of cutters 4 rotate synchronously. The assembly roller 2 is arranged above the pet urine pad. The plurality of cutters 4 in rotation can contact the pet urine pad. When the cutters 4 contact the pet urine pad, a single pet urine pad is cut and separated. By arranging a plurality of cutters 4 on the assembly roller 2 to undertake cutting work respectively, the service life of a single cutter 4 can be improved.

[0028] The plurality of cutters 4 are different in wear degree after long-term use. In the prior art, the cutters 4 are usually welded or integrally formed on the assembly roller 2. When workers replace the cutters 4 with serious wear, the assembly roller 2 and the remaining cutters 4 need to be replaced together, which causes waste of resources. To solve this problem, the present embodiment refers to Figure 4 and Figure 5A plurality of trapezoidal grooves 23 are annularly arranged on the circumferential side wall of the assembly roller 2, the width of the trapezoidal groove 23 decreases in the direction away from the axis of the assembly roller 2, and one end of the trapezoidal groove 23 extends to the edge of the assembly roller 2, a trapezoidal block 41 is slidably arranged in the trapezoidal groove 23, the cutter 4 is fixedly connected to the side of the trapezoidal block 41 away from the axis of the assembly roller 2, when the assembly roller 2 drives the cutter 4 to rotate, the trapezoidal block 41 and the trapezoidal groove 23 cooperate to limit the cutter 4 from moving away from the axis of the assembly roller 2 under the action of centrifugal force, ensuring the stability of the cutter 4 during rotation, a turntable 5 is coaxially arranged on one side of the assembly roller 2, a ring groove 24 is coaxially arranged on the side of the assembly roller 2 close to the turntable 5, an inner embedding ring 52 is rotatably arranged in the ring groove 24, one end of the inner embedding ring 52 is fixedly arranged on the turntable 5, and the side section of the inner embedding ring 52 and the ring groove 24 are both L-shaped structures, so that the inner embedding ring 52 cannot be removed from the ring groove 24, the inner embedding ring 52 and the ring groove 24 cooperate to coaxially and rotatably connect the turntable 5 and the assembly roller 2, a notch 51 is arranged on the turntable 5, the width of the notch 51 is greater than the width of the trapezoidal groove 23, the trapezoidal block 41 can pass through the notch 51, and a plug hole 54 is arranged on the turntable 5, a screw 53 is slidably and rotatably arranged in the plug hole 54, a threaded groove 25 is arranged on the side of the assembly roller 2 close to the turntable 5, when one end of the screw 53 is threadedly connected in the threaded groove 25, the screw 53 limits the rotation of the turntable 5, at this time the notch 51 is not in communication with any one of the trapezoidal grooves 23, the turntable 5 blocks one end of the trapezoidal groove 23, and one end of each of the plurality of trapezoidal blocks 41 is in contact with the turntable 5, at this time the turntable 5 blocks the trapezoidal block 41 from being transversely removed from the trapezoidal groove 23, so as to independently and detachably install the plurality of cutters 4 on the circumferential side wall of the assembly roller 2, facilitating workers to individually replace the cutter 4 that is severely worn.

[0029] When the worker replaces the cutter 4 that is severely worn, first, one end of the screw 53 is screwed out of the threaded groove 25, and then the worker rotates the turntable 5, when the turntable 5 rotates, the notch 51 is in communication with the plurality of trapezoidal grooves 23 in turn, referring to Figure 6After the notch 51 is rotated to the position communicated with the corresponding trapezoidal groove 23, the rotation of the rotating disc 5 is stopped, the corresponding trapezoidal groove 23 is the trapezoidal groove 23 where the trapezoidal block 41 on the damaged tool 4 is placed, then the worker pulls the damaged tool 4 transversely, so that the trapezoidal block 41 on the damaged tool 4 is moved out of the trapezoidal groove 23 through the notch 51, in the process, the two ends of the tool holder 1 do not block one side of the rotating disc 5, that is, the two ends of the tool holder 1 cannot block the trapezoidal grooves 23 on the assembling roller 2, so that the extension direction of at least one trapezoidal groove 23 is not blocked by the tool holder 1, before the tool 4 is slid out of the trapezoidal groove 23, the notch 51 on the rotating disc 5 is rotated to the position not blocked by one end of the tool holder 1, then the tool 4 is pulled out of the trapezoidal groove 23 and the notch 51, the tool holder 1 does not block the movement of the tool 4, the worker can disassemble the damaged tool 4 from the assembling roller 2 without disassembling the assembling roller 2 from the tool holder 1, the efficiency of the worker in disassembling the damaged tool 4 is improved, after the worker inserts the trapezoidal block 41 on the new tool 4 into the corresponding trapezoidal groove 23, the rotating disc 5 is rotated to reset, then the screw 53 is screwed into the threaded groove 25 to fix the position of the rotating disc 5, that is, the separate replacement of the damaged tool 4 is completed, compared with replacing the assembling roller 2 and all the tools 4, the material is saved.

[0030] The basic principle, main features and advantages of the utility model are shown and described above.
