In addition, while the sliding table 2 is moved away, the shifting rod 4 is driven, so that a knife wheel at the end of the shifting rod 4 falls into the second channel 31, and the knife wheel further cuts and crushes the cuttings in the second channel 31. The end part of the second channel 31 close to the sliding table 2 is provided with a slope. When the slide table 2 slides, the cutter wheel can roll into the second channel 31 along the slope.

Further, the cutter wheel includes: the device comprises a shell 5, a mandrel, a sliding block 29, a first rod 21, a second rod 22, a brush piece 28 and cutter teeth, wherein the mandrel is fixedly arranged in the middle of the shell 5 and is coaxially and fixedly connected with the second shaft 12; the first rod 21 is arranged inside the shell 5, the first rod 21 is arranged along the radial direction of the mandrel, one end of the first rod 21 is fixedly connected with the shell 5, and the other end of the first rod 21 is fixedly connected with the side wall of the mandrel; the sliding block 29 is slidably connected to the first rod 21, and the housing 5 is provided with a first slot which is arranged along the axial direction of the mandrel; the third rod 23 is slidably connected in the first slot, one end of the third rod 23 extends to the outside of the housing 5, and one end of the third rod 23 located at the outside of the housing is fixedly connected with the brush piece 28; second pole 22 arranges third pole 23 with between the slider 29, the one end of second pole 22 with third pole 23 is articulated, the other end of second pole 22 with slider 29 is articulated, the cover is equipped with the extension spring on the third pole 23, the one end of extension spring with dabber fixed connection, the other end of extension spring with slider 29 fixed connection. In the working process of the cutter wheel, the second shaft 12 drives the mandrel to rotate so as to drive the whole shell 5 to rotate, and the sliding block 29 slides along the first rod 21 to drive the tension spring to extend due to the centrifugal force of the sliding block 29 and the tension spring. At the same time, the movement of the slider 29 moves the second rod 22 and the third rod 23, pushing the third rod 23 towards the outside of the casing 5. Thereby enabling the brush piece 28 to be close to the inner wall of the second channel 31, and enabling the brush piece 28 to brush the inner wall of the second channel 31 during the rotation of the knife wheel. Meanwhile, the cutter wheel rotates after penetrating into the second channel 31, so that the problem that the brush piece 28 is always kept outside the shell 5 to cause difficulty in penetrating into the second channel 31 can be effectively avoided. The cutter wheel further comprises a fourth rod 24 and a fifth rod 25, a second slot is formed in the shell 5, the second slot is arranged between the mandrel and the first slot, and the second slot is arranged along the axial direction of the mandrel. Said fourth bar 24 is arranged between said mandrel and said second bar 22, said fifth bar 25 being in sliding connection with said second slot; the sliding block 29 moves the fifth rod 25 and the third rod 23 to slide in opposite directions. Likewise, during the rotation of the knife wheel, the movement of the slider 29 along the first rod 21 causes the movement of the fourth rod 24 and the fifth rod 25, the fifth rod 25 sliding into said housing 5, so that, when the knife wheel is not rotating, the fifth rod 25 protrudes outside said housing 5, so that the housing 5 must not enter the second channel 31. When the cutter wheel rotates, the fifth rod 25 retracts into the housing 5, and the housing 5 loses support and falls into the second channel 31. This allows the cutter wheel to rotate, thereby spontaneously entering the second channel 31.

Further, a roller 30 is arranged on one side of the base 6, a third channel communicated with the cavity is formed in the base 6, the roller 30 is arranged at the outlet end of the third channel, and the roller 30 is fixedly sleeved on the third shaft 13. Considering that liquid components such as cutting fluid and the like are removed along with the chips in the use of the machine tool 1, the liquid components deposited in the cavity can be guided to the roller 30 through the third channel, and a flocculating agent is added into the roller 30, so that the roller 30 rotates along with the third shaft 13, the deposition of impurities in the roller is promoted, and the recovery of the cutting fluid is facilitated. A tube 26 is fixedly mounted on the outer wall of the housing 5, the tube 26 is used for storing detergent or decontaminant, a valve 27 is arranged at the lower end of the tube 26, a piston 20 is slidably connected in the tube 26 in a water-tight manner, a push rod 19 is arranged at one end of the piston 20 far away from the valve 27, one end of the push rod 19 is fixedly connected with the piston 20, and the other end of the push rod 19 is fixedly connected with the side wall of the fifth rod 25. When the housing 5 rotates to drive the sliding block 29 to move, the fifth rod 25 moves inwards to drive the push rod 19 to push the piston 20. And then will the sanitizer in the body is pushed out from the valve, can get rid of the sanitizer on the second passageway through the effect of centrifugal force to the realization is when rotating, carries out spraying of sanitizer, and, like the cooperation with the brush piece can reach good clean effect.
