[0011] Preferably, one end of the sieve plate is fixedly connected to a fixing bar, and one side surface of the fixing bar is fixedly connected to a handle.

[0012] Preferably, a limiting block is fixedly connected to one side surface of the machine tool body, one end of the limiting block is slidably engaged with the limiting strip, the top of the limiting block is fixedly connected with a spring, the top of the spring is fixedly connected to the inner wall of the limiting strip, and the bottom end of the limiting strip is fixedly connected with a connecting rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. Connect the water pipe on the cutting fluid nozzle through the limit block, and use the water pump to spray the cutting fluid at the bottom of the machine tool body onto the cutting metal. During the cutting process, the sprayed cutting fluid will flow from the cutting seat to the sieve plate 1 along with the cut chips. At this time, part of the cutting fluid falls on the sieve plate 2 through the sieve holes on the sieve plate 1, and the remaining cutting fluid mixed with the chips flows from the gap into the storage cabin, where the chips will be retained by the filter trough. The remaining cutting fluid flows through the filter trough to the sieve plate 2, and falls from the sieve holes on the sieve plate 2 to the inner bottom of the machine tool body. The device can filter the used cutting fluid, and then use the water pump to repeatedly recycle the recovered cutting fluid, thereby effectively avoiding the waste of resources.

[0015] 2. By providing a sieve plate 1, after long-term use, when the surface of the sieve plate 1 is blocked and it is necessary to clean the surface of the sieve plate 1, the person manually pulls the connecting rod to drive the limit bar to move downward, thereby releasing the clamping state between the limit bar and the fixing bar. The person can hold the handle to pull the sieve plate 1 out from the inside of the machine tool body, thereby cleaning the sieve plate 1, and then reinsert it into the inside of the machine tool body after cleaning. At this time, the elastic force of the spring is applied to the limit bar, so that one side of the limit bar abuts against the surface of the fixing bar, thereby fixing the sieve plate 1 inside the machine tool body, facilitating the disassembly and assembly of the sieve plate 1. At the same time, during use, the reciprocating screw is driven by the motor to rotate, thereby driving the scraper to reciprocate, effectively avoiding the filter tank from being blocked, and greatly improving the recovery efficiency of the cutting fluid.

[0023] Among them, the sieve plate 1 5 is inclined, the groove 3 is located at the bottom of the sieve plate 1 5, the filter groove 9 is located directly below the groove 3, and the filter groove 9 is located at the top of the sieve plate 2 10. The sprayed cutting fluid will flow from the cutting seat 2 to the sieve plate 1 5 along with the cut chips. At this time, part of the cutting fluid passes through the sieve holes on the sieve plate 1 5 and falls on the sieve plate 2 10. The remaining cutting fluid mixed with the chips flows from the groove 3 into the storage compartment 8, wherein the chips will be retained by the filter groove 9. The remaining cutting fluid flows through the filter groove 9 to the sieve plate 2 10, and falls from the sieve holes on the sieve plate 2 10 to the inner bottom of the machine tool body 1. The device can filter the used cutting fluid, and then use the water pump 14 to repeatedly recycle the recovered cutting fluid.

[0024] Among them, a motor 11 is fixedly connected to one side of the storage compartment 8, and the output shaft of the motor 11 is fixedly connected to a reciprocating screw 12. The reciprocating screw 12 is located inside the storage compartment 8. The reciprocating screw 12 is driven to rotate by the motor 11, thereby driving the scraper 19 to reciprocate, effectively preventing the filter tank 9 from being blocked.

[0025] The surface of the reciprocating screw 12 is threadedly sleeved with a sliding sleeve block 13 , one side of the sliding sleeve block 13 is fixedly connected with a scraper plate 19 , and the scraper plate 19 abuts against the side surface of the filter tank 9 .

[0026] Among them, one end of the sieve plate 5 is fixedly connected to a fixing strip 6, one side surface of the fixing strip 6 is fixedly connected to a handle 7, one side surface of the machine tool body 1 is fixedly connected to a limiting block 15, one end of the limiting block 15 is slidably connected to a limiting strip 16, the top of the limiting block 15 is fixedly connected to a spring 17, the top of the spring 17 is fixedly connected to the inner wall of the limiting strip 16, and the bottom end of the limiting strip 16 is fixedly connected to a connecting rod 18. When the surface of the sieve plate 5 is blocked, it is necessary to clean the surface of the sieve plate 5. The person manually pulls the connecting rod 18 to drive the limit bar 16 to move downward, releasing the clamping state between the limit bar 16 and the fixing bar 6. The person manually holds the handle 7 to pull the sieve plate 5 out from the inside of the machine tool body 1, thereby cleaning the sieve plate 5, which can be reinserted into the inside of the machine tool body 1 after cleaning. At this time, the elastic force of the spring 17 is applied to the limit bar 16, so that one side of the limit bar 16 abuts against the surface of the fixing bar 6, thereby fixing the sieve plate 5 inside the machine tool body 1, which is convenient for the disassembly and assembly of the sieve plate 5.

[0027] Working principle: when the device is in use, the water pump 14 is used to spray the cutting fluid at the bottom of the machine tool body 1 onto the cut metal. During the cutting process, the sprayed cutting fluid will flow from the cutting seat 2 to the sieve plate 1 5 along with the cut chips. At this time, part of the cutting fluid passes through the sieve holes on the sieve plate 1 5 and falls on the sieve plate 2 10. The remaining cutting fluid mixed with the chips flows from the slot 3 into the storage compartment 8, where the chips will be screened by the filter slot 9. The remaining cutting fluid flows through the filter slot 9 to the sieve plate 2 10 and falls from the sieve holes on the sieve plate 2 10 to the inner bottom of the machine tool body 1. The device can filter the cutting fluid after use. When the surface of the sieve plate 1 5 is blocked, the surface of the sieve plate 1 5 needs to be cleaned. When cleaning, the person manually pulls the connecting rod 18 to drive the limit bar 16 to move downward, releasing the clamping state between the limit bar 16 and the fixing bar 6. The person can hold the handle 7 to pull the sieve plate 5 out from the inside of the machine tool body 1, thereby cleaning the sieve plate 5. After cleaning, it can be reinserted into the inside of the machine tool body 1. At this time, the elastic force of the spring 17 is applied to the limit bar 16, so that one side of the limit bar 16 abuts against the surface of the fixing bar 6, thereby fixing the sieve plate 5 inside the machine tool body 1, facilitating the disassembly and assembly of the sieve plate 5. At the same time, during use, the reciprocating screw 12 is driven to rotate by the motor 11, thereby driving the scraper 19 to reciprocate, effectively preventing the filter slot 9 from being blocked.
