[0046] like Figure 6 and Figure 7 , by turning on the second servo motor 42, the rotating shaft of the second servo motor 42 drives the second screw rod 41 to rotate. Because one end of the second screw rod 41 passes through the second slider 38 and is threadedly connected to the second slider 38, when the second screw rod 41 rotates, the second slider 38 can be pushed to slide along the width direction of the first slide groove 35 in the mounting box 37. At this time, the distance between the movable tool holder 29 and the processing screw can be adjusted. When the adjustment of the movable tool holder 29 is completed, by turning on the first servo motor 40, the rotating shaft of the first servo motor 40 drives the first screw rod 39 to rotate.

At this time, because the fixed plate 21 is tilted, the waste material and coolant dropped onto the fixed plate 21 will pass through the fixed plate 21 toward the direction close to the guide box 49. When the waste material and coolant fall from the fixed plate 21 into the guide box 49, the waste material and coolant can be discharged into the separator through the connecting pipe 53 on the guide box 49, and then the solid-liquid separation is performed through the separator. The liquid separated from the solid and liquid drips into the liquid collecting box 51 for collection, and the solid separated from the solid-liquid separation is transferred to the collecting box 52 through the separator. It is simple and convenient to use.

The first filter plate 59 at the end tube mouth, and the two first filter plates 59 are provided with a limit plate 60 at one end near the hinge point of the first filter plate 59 and the vertical tube 57, the top of the mounting plate 50 is provided with a vertical plate 61, and a fixing ring 62 is provided on one side of the vertical plate 61, the fixing ring 62 is coaxially arranged with the rotating shaft 54, and an arc groove 63 is provided on one side of the outer wall of the fixing ring 62, and the arc groove 63 is connected to the bottom end of the fixing ring 62, and the two limit plates 60 are provided with a spherical protrusion 64 at one end away from the first filter plate 59, and the top of one of the protrusions 64 contacts the bottom end of the fixing ring 62, and the top of the other protrusion 64 contacts the top groove wall of the arc groove 63.

[0051] like Figure 5 and Figure 8When the protrusion 64 contacts the bottom end of the fixing ring 62, the first filter plate 59 closes the bottom end of the vertical cylinder 57. When the protrusion 64 contacts the top wall of the arc groove 63, the first closing plate releases the seal on the vertical cylinder 57. The waste and coolant in the guide box 49 enter one of the vertical cylinders 57 through the connecting pipe 53 and one of the circular grooves 56 corresponding to the connecting pipe 53. At this time, the waste and coolant can be filtered by the first filter plate 59 that closes the bottom end of the vertical cylinder 57. The liquid passes through the first filter plate 59. The filter plate 59 drips into the liquid collecting box 51, and the solid remains in the vertical cylinder 57 on the first filter plate 59. When one of the vertical cylinders 57 corresponds to the connecting pipe 53, the other vertical cylinder 57 is located above the collecting box 52. After the first filter plate 59 on one of the vertical cylinders 57 has been used for a certain period of time, the first motor 58 is turned on, and the rotating shaft of the first motor 58 drives the rotating shaft 54 ​​to rotate. The rotating shaft 54 ​​drives the turntable 55, the two vertical cylinders 57, the two first filter plates 59, the two limit plates 60, the two The protrusion 64 rotates along the rotation axis of the rotating shaft 54 ​​until the positions of the two vertical cylinders 57 are exchanged. After the exchange is completed, under the influence of gravity, and through the cooperation of one of the protrusions 64 and the arc-shaped groove 63, the first filter plate 59 located above the collection box 52 can be rotated along the hinge point between the first filter plate 59 and the vertical cylinder 57 until the protrusion 64 contacts the top groove wall of the arc-shaped groove 63. At this time, the first filter plate 59 can be tilted, and the vertical cylinder 57 is opened. At this time, the first filter plate 59 is in contact with the top groove wall of the arc-shaped groove 63. The solids in the vertical cylinder 57 will fall into the collecting box 52, realizing solid-liquid separation. The vertical plate 61 is located in the fixing ring 62. The vertical plate 61 and the protrusion 64 do not affect each other. When the protrusion 64 moves out of the arc groove 63, the arc groove 63 can push the protrusion 64 to drive the limit plate 60 and the first filter plate 59 to rotate along the hinge point between the first filter plate and the vertical cylinder 57 until the protrusion 64 contacts the bottom end of the fixing ring 62. At this time, the first filter plate 59 closes the bottom end of the vertical cylinder 57, which is simple and convenient to use.

[0053] like Figure 9 and Figure 10 and Figure 11 , the waste material and coolant in the guide box 49 are discharged into one of the mounting cylinders 70 through the connecting pipe 53. At this time, the waste material and coolant can be filtered through the second filter plate 71 in one of the mounting cylinders 70. At this time, the liquid passes through the second filter plate 71 and drips into the liquid collecting box 51. The solid remains on the second filter plate 71 in the mounting cylinder 70. When the second filter plate 71 on one of the mounting cylinders 70 is used for a certain period of time, the second motor 72 is turned on. At this time, the rotating shaft of the second motor 72 drives the disc 65 to rotate, and the disc 65 drives each mounting cylinder 70. The mounting cylinder 70 rotates along the rotation axis of the disc 65 until the next mounting cylinder 70 rotates to the bottom of the connecting pipe 53.
