When the metal cutting machine is used, the motor 10 rotates, the third belt pulley 73 is driven to rotate, the third belt pulley 73 drives the fourth belt pulley 75 through the second belt 74, the eccentric wheels 72 are driven to rotate when the fourth belt pulley 75 rotates (the two eccentric wheels 72 are connected through the synchronous belt 76, the phenomenon of dislocation of the two eccentric wheels 72 is avoided, the two symmetrical eccentric wheels 72 drive the sieve plate 21 to move horizontally, the sieve plate 21 is made to shake more stably and uniformly, the eccentric wear degree is reduced), the round rods 78 on the eccentric wheels 72 move in the long round holes in the bottom of the sieve plate, the sieve plate 21 is driven to move horizontally back and forth on the fixing plate 12, and large metal cutting particles fall below through the sieve holes 77 formed in the sieve plate 21.

The motor 10 drives the eccentric wheel 72 to rotate, so that the sieve plate 21 is screened back and forth on the fixed plate 12 in a reciprocating manner, and massive metal cutting materials are discharged from a sieve opening 77 formed in the edge of the sieve plate 21, so that the sieve plate has higher continuous operation performance, manual cleaning is not needed, and the labor cost is saved.

As a further scheme of the invention, the anti-scattering plate 81 is fixedly arranged on the outer ring of the shielding plate 62, so that the problem that the service life of equipment is reduced due to the fact that particle metal in the impurity-containing cutting fluid increases abrasion among parts when the sieve plate 21 throws the impurity-containing cutting fluid everywhere in working hours is effectively solved.

As a further scheme of the invention, the two ends of the drainage groove 38 are provided with heightened vertical surfaces, so that liquid can flow out along with the outer wall of the centrifugal shell 31 in the centrifugal process and cannot splash to the nearby roller brush 50, and the problems that the roller brush 50 is polluted by oil and the cleaning capacity is reduced are solved.

As a further scheme of the invention, the roller brush 50 is made of an oleophobic material, so that the roller brush 50 is not stained with cleaning matters, and the circular cleaning capability is stronger.

As a further scheme of the invention, the sliding column 22 adopts antifriction materials, so that the friction force of the equipment is reduced, and the energy is saved.

Compared with the prior art, the invention has the beneficial effects that:

One specific application of this embodiment is: when the invention is used, the equipment is assembled, used cutting fluid is directly sprayed into the sliding plate 11, the motor 10 is started to

gear 61, the dial gear 63 drives the rotating roller 47 to move through the shifting fork 64 at the outer side, the rotating roller 47 drives the dipping plate 49 fixed at the lower side to surround the ring groove 43 and to slide along the inner wall of the centrifugal shell 31 (the lower end of the dipping plate 49 is not jointed with the bottom surface of the inner wall of the centrifugal shell 31, the sedimentation of cutting particles is avoided, the equipment is easy to cause a blocked state during starting), the rotating speed of the decelerated dial gear 63 is lower than that of the central gear 34, meanwhile, a first belt pulley 66 coaxially fixed on the driving roller 32 drives a second belt pulley 67 to rotate through a first belt 68, the second belt pulley 67 drives the roller brush 50 to rotate clockwise, the cutting fluid with impurities flows along the sliding plate 11 to the direction of the slotted hole 13, when the cutting fluid flows into the slotted hole 13, the cutting fluid flows to the upper side of the sieve plate 21 at the lower side along the extension ring plate 14 (the extension ring plate 14 avoids the inconsistent flow direction of the cutting fluid containing the impurities and is coated on the lower side of the sliding plate 11 everywhere), when the cutting fluid containing the impurities flows onto the sieve plate 21, the triangular ribs 23 on the sieve plate can block the cutting waste with larger particles, the cutting fluid mixed with small particle waste flows to the blanking holes 24 at the lowest point in the middle of the sieve plate 21 through the diversion holes 24 on the triangular ribs 23 (the diversion holes 24 are thinner as the diversion holes 24 are closer to the blanking holes 25, the layered screening is carried out, the screening effect is better), and when the cutting fluid carrying the small impurities enters the mechanism 3 through the blanking holes 25 and the gaps of the shielding plates 62 (the baffle plate 62 prevents the impurity cutting fluid from directly spraying on the planetary gear set, and avoids the phenomenon of noise accelerated abrasion during the working process of the planetary gear set) when the cutting fluid enters the centrifugal shell 31, the cutting fluid is stirred by the disturbance plate 33 at the moment, the impurity cutting fluid starts to rotate in the centrifugal shell 31 at the moment, after the impurity cutting fluid passes through the rotary dip plate 49 (due to the action of the planetary gear 61, the rotating speed of the dip plate 49 is lower than that of the disturbance plate 33 at the moment, the existing speed difference enables the impurity particles to rub against the dip plate 49, so that the impurity particles are better adsorbed by the dip plate 49), the impurity cutting fluid flows to the drainage groove 38 at the lower part along the outer wall of the centrifugal shell 31 through the filter holes 35 on the centrifugal shell 31, then the filtered cutting fluid is collected by the discharge port 39 at the lowest point of the drainage groove 38, and simultaneously moves in the annular groove 43 along with the dip plate 49, when the dip plate 49 moves to the turnover area 44, the steering gear 48 is firstly meshed with the forward rotating arc rack 45, the dipping plate 49 is overturned clockwise (as shown in figure 11), when the dipping plate 49 is overturned, the roller brush 50 brushes out the cutting particles adsorbed on the dipping plate 49 (the reverse rotating direction of the dipping plate 49 is the same as the moving direction of the roller brush 50, the hair clamping phenomenon cannot occur at the moment, the overflow-proof plate 41 completely overturns the arc line of the dipping plate 49, collision cannot occur at the moment, unfiltered cutting fluid is prevented from flowing out of the avoidance hole 36, when the steering gear 48 moves to the tail end of the forward rotating arc rack 45 along with the continuous movement, the inner side of the arc surface of the dipping plate 49 is completely overturned to the outer side at the moment, the roller brush 50 contacts the inner side arc surface of the whole dipping plate 49, the cutting particles on the dipping plate 49 are completely brushed out, when the movement continues, the steering gear 48 is meshed with the reverse rotating arc rack 46, at the moment, the dipping plate 49 rotates and closes anticlockwise again to return to the original state, the plurality of dipping plates 49 are turned over in sequence, and the states are the same, which is not described herein.
