[0032] It is understandable that, referring to Figure 1 , Figure 2 ,as well as Figures 4 to 6The cutting fluid filtering device of the utility model comprises a frame 100, a filtering mechanism 200 and a liquid inlet mechanism 300. The frame 100 is provided with a silo 110, the silo 110 is used to store a filter paper roll 111, and the filter paper roll 111 is used to release the filter paper; the filtering mechanism 200 comprises a conveying mesh belt 210 and two pressing wheels 220, the conveying mesh belt 210 is arranged in the frame 100, the two pressing wheels 220 are both rotatably connected to the frame 100, and the two pressing wheels 220 are respectively located on both sides of the conveying mesh belt 210 The filter paper is located between the pressure wheel 220 and the conveyor belt 210, and the conveyor belt 210 is used to drive the filter paper to be transported; the liquid inlet mechanism 300 includes a liquid inlet pipe 310 and a splash-proof bag 320, the liquid inlet pipe 310 is arranged on the frame 100 to output cutting fluid to the filter paper, the splash-proof bag 320 is sleeved on the liquid inlet pipe 310 and is located between the two pressure wheels 220, the splash-proof bag 320 is provided with a plurality of first through holes 321, the plurality of first through holes 321 are arranged at intervals, and the liquid inlet pipe 310 is connected to the first through holes 321.

[0033] The two pressing wheels 220 are rotatably connected to the frame 100, and the two pressing wheels 220 are both in contact with the conveyor mesh belt 210. The two pressing wheels 220 are respectively located on both sides of the conveyor mesh belt 210. The filter paper roll 111 is arranged in the silo 110. The filter paper roll 111 can move in the silo 110 so that the filter paper can be released. The filter paper is inserted between the pressing wheel 220 and the conveyor mesh belt 210. The liquid inlet pipe 310 outputs cutting fluid to the filter paper so that the filter paper can filter out debris in the cutting fluid. The filter paper is driven to be transported by the conveyor mesh belt 210, and the filter paper can be replaced in time, so that the filter paper can maintain the filtering performance and improve the filtering effect of the cutting fluid. The splash-proof pocket 320 is sleeved in the liquid inlet pipe 310, and the cutting fluid output from the liquid inlet pipe 310 is received by the splash-proof pocket 320, thereby slowing down the flow speed of the cutting fluid, allowing the cutting fluid to disperse and flow out from the plurality of first through holes 321, reducing the impact force of the cutting fluid on the filter paper, and slowing down the fluctuation of the cutting fluid, reducing the possibility of debris being washed to the edge of the filter paper, so that the cutting fluid can stably pass through the filter paper, thereby improving the filtering effect of the cutting fluid.

[0034] It should be noted that the filter paper roll 111 is movably arranged in the silo 110, and the filter paper released by the filter paper roll 111 is located between the conveyor mesh belt 210 and the pressure wheel 220. The filter paper can be continuously released through the cooperation of the conveyor mesh belt 210 and the pressure wheel 220, and the filter paper can be automatically replaced to avoid excessive accumulation of debris on the filter paper, so that the filter paper can maintain its filtering ability.

[0035] In addition, the cutting fluid is input into the splash-proof pocket 320 from the liquid inlet pipe 310 to prevent the cutting fluid from directly impacting the filter paper, and can guide the cutting fluid to be output from the middle of the filter paper, thereby reducing the debris from being washed to the edge of the filter paper, allowing the debris to be evenly deposited on the filter paper, thereby improving the uniformity of the use of the filter paper, extending the service life of the filter paper, and improving the filtering effect.

[0036] It is understandable that, referring to Figure 4 and Figure 6 The interior of the splash-proof pocket 320 is fixedly connected with a partition 322, and the partition 322 is provided with a plurality of second through holes 323, and the plurality of second through holes 323 are arranged at intervals, and the first through hole 321 is connected with the second through holes 323. By arranging the partition 322 inside the splash-proof pocket 320, when the cutting fluid outputted by the liquid inlet pipe 310 enters the splash-proof pocket 320, it can abut against the partition 322, and the impact force of the cutting fluid can be absorbed by the partition 322, and the partition 322 is provided with a plurality of second through holes 323, and the cutting fluid can be dispersed through the plurality of second through holes 323, and then the cutting fluid flows out from the plurality of first through holes 321, so that the flow speed of the cutting fluid can be slowed down, so that the cutting fluid can be stably outputted to the filter paper, the filter paper can be prevented from being damaged, and the reliability of the cutting fluid filtering device is improved.

[0037] It is understandable that, referring to Figure 4 and Figure 6 , two connecting plates 324 are arranged at the upper end of the splash-proof pocket 320, and fasteners 325 are passed through the two connecting plates 324. The fasteners 325 can adjust the spacing between the two connecting plates 324 so that the two connecting plates 324 can be clamped on the liquid inlet pipe 310. The two connecting plates 324 are arranged at the upper end of the splash-proof pocket 320, and the two connecting plates 324 are located on both sides of the splash-proof pocket 320. The fasteners 325 pass through the two connecting plates 324, and the fasteners 325 can drive the two connecting plates 324 to approach each other so that the two connecting plates 324 can be clamped in the liquid inlet pipe 310, so that the splash-proof pocket 320 can be fixed on the liquid inlet pipe 310, and the position of the splash-proof pocket 320 is conveniently positioned.

[0038] It should be noted that the fastener 325 includes a first bolt and a first nut. The first bolt is passed through the two connecting plates 324, and then the first nut is screwed into the first bolt so that the first bolt and the two connecting plates 324 can be fitted on the liquid inlet pipe 310, which can facilitate the adjustment of the position of the splash guard 320. Moreover, through the cooperation of the first bolt and the first nut, the two connecting plates 324 can be clamped on the liquid inlet pipe 310, thereby improving the position stability of the splash guard 320 and improving the reliability of the cutting fluid filtering device.

[0039] It is understandable that, referring to Figure 5The filter mechanism 200 also includes a controller and a float 230. The float 230 and the liquid inlet pipe 310 are both electrically connected to the controller. The float 230 is used to detect the liquid level of the cutting fluid. The controller can control the liquid inlet pipe 310 to open or close. The float 230 is movably connected to the frame 100, and the float 230 floats on the cutting fluid. The liquid level of the cutting fluid in the frame 100 can be detected by the float 230, so that the controller can control the liquid inlet pipe 310 to open or close according to the liquid level of the cutting fluid, and then control the flow of the cutting fluid, so as to prevent the cutting fluid from overflowing from the edge of the filter paper, so that the cutting fluid can be filtered stably and the filtering effect of the cutting fluid is improved.

[0040] It should be noted that the liquid inlet pipe 310 is connected to a water pump, which can extract cutting fluid and output it to the filter paper. The water pump is turned on or off by a controller, so as to control the flow of the cutting fluid.

[0041] The controller may be a single chip microcomputer, a programmable logic controller, or an industrial computer, which will not be described in detail here.

[0042] Specifically, refer to Figure 5 and Figure 6 The first through holes 321 on one side of the splash-proof pocket 320 close to the float 230 are arranged in two groups, and the two groups of first through holes 321 are respectively located on both sides of the float 230. By arranging the two groups of first through holes 321 respectively on both sides of the float 230, when the cutting fluid is output from the two groups of first through holes 321, the cutting fluid can flow out from both sides of the float 230, thereby reducing the impact of the cutting fluid on the float 230, allowing the float 230 to remain stable, preventing the influence on the liquid level detection of the cutting fluid, and improving the reliability of the cutting fluid filtering device.

[0043] Specifically, refer to Figure 1 and Figure 4 The filter mechanism 200 further includes a detection sensor 240. The detection sensor 240 and the conveyor belt 210 are electrically connected to the controller. The detection sensor 240 is arranged on the frame 100. The detection sensor 240 is used to detect the filter paper. The controller can control the conveyor belt 210 to start or stop. The detection sensor 240 is arranged on the frame 100. The filter paper can be detected by the detection sensor 240, so that the conveyor belt 210 can be controlled to start or stop by the controller to prevent the cutting fluid from flowing out without being filtered by the filter paper.

[0044] It should be noted that the detection sensor 240 is arranged upstream of the conveyor mesh belt 210. When the detection sensor 240 detects the filter paper, the controller controls the conveyor mesh belt 210 to open, so that the conveyor mesh belt 210 can drive the filter paper roll 111 to release the filter paper, thereby facilitating the filter paper to filter the cutting fluid; when the detection sensor 240 cannot detect the filter paper, the controller controls the conveyor mesh belt 210 to close, to prevent the filter paper between the conveyor mesh belt 210 and the pressure wheel 220 from being consumed, to avoid the cutting fluid from being output without being filtered by the filter paper, and to improve the reliability of the cutting fluid filtering device.

[0045] The detection sensor 240 may be an infrared sensor or an ultrasonic sensor, as long as it can detect filter paper, which will not be described in detail here.

[0046] In addition, when the detection sensor 240 cannot detect the filter paper, the controller controls the water pump to turn off to stop the input of cutting fluid, making it convenient for the staff to replace the filter paper roll and improving the reliability of the cutting fluid filtering device.

[0047] It is understandable that, referring to Figure 1 and Figure 4 A waste box 120 is provided on the side of the frame 100 away from the silo 110, and the waste box 120 is docked with the conveyor mesh belt 210 to accommodate filter paper. The waste box 120 is provided on the side of the frame 100 away from the silo 110, and the waste box 120 is docked with the conveyor mesh belt 210 so that the waste box 120 can carry the filter paper output by the conveyor mesh belt 210, so that the used filter paper can be automatically collected, the filter paper can be automatically replaced, and the filter paper can be prevented from accumulating outside the frame 100, thereby improving the convenience of using the cutting fluid filtering device.

[0048] Specifically, refer to Figure 4 and Figure 7 , the first through hole 321 on the bottom side of the splash-proof pocket 320 is arranged on a side close to the waste bin 120. The first through hole 321 on the bottom side of the splash-proof pocket 320 is arranged on a side close to the waste bin 120, so that when the cutting fluid is discharged from the bottom side of the splash-proof pocket 320, the cutting fluid can be discharged in a direction close to the waste bin 120, thereby guiding the cutting fluid to be output to a position close to the output end of the filter paper, so that the filter paper can quickly bring the debris into the waste bin 120, thereby reducing the time for the debris to be deposited on the filter paper, so that the filter paper with the debris can be quickly discharged into the waste bin 120, avoiding affecting the filtering effect of the cutting fluid, and improving the reliability of the cutting fluid filtering device.

[0049] Specifically, refer to Figure 2 and Figure 4The frame 100 is rotatably connected with a cover 130, and the cover 130 is arranged above the waste bin 120. The cover 130 is rotatably connected to the frame 100, and the cover 130 is arranged above the waste bin 120 so that the cover 130 can cover the output end of the conveyor mesh belt 210, thereby guiding the filter paper to smoothly enter the waste bin 120, preventing the filter paper from sliding out of the waste bin 120, and conveniently storing the filter paper in the waste bin 120. In addition, by setting the cover 130, the debris falling off the filter paper can be concentrated in the waste bin 120, preventing the debris from floating, preventing environmental pollution, and improving the user experience.

[0050] It is understandable that, referring to Figure 2 and Figure 3 The conveyor mesh belt 210 is connected to two rollers 211, and the two rollers 211 cooperate to tension the conveyor mesh belt 210. The frame 100 is provided with a fixed seat 141 and a movable block 142. The fixed seat 141 is penetrated by a screw 143, and the screw 143 is connected to the movable block 142. The screw 143 is threadedly connected to two nuts 144, and the two nuts 144 are respectively located on both sides of the fixed seat 141, and one of the rollers 211 is connected to the movable block 142. One of the rollers 211 is rotatably connected to the frame 100, and the other roller 211 is connected to the movable block 142. The two rollers 211 cooperate to tension the conveyor mesh belt 210. The fixed seat 141 is fixedly connected to the frame 100, and the screw 143 is threadedly connected to the fixed seat 141, and the screw 143 is connected to the movable block 142. By driving the screw 143 to rotate, the screw 143 can drive the movable block 142 to move toward or away from the fixed seat 141, so that the position of the roller 211 can be easily adjusted, so that the conveyor mesh belt 210 can be wrapped in the pressure wheel 220 to tension the filter paper, avoid wrinkles in the filter paper, prevent debris from seeping out from the gap between the conveyor mesh belt 210 and the pressure wheel 220, and improve the reliability of the cutting fluid filtering device.

[0051] In addition, the screw 143 is threadedly connected to two nuts 144, and the two nuts 144 are respectively located on both sides of the fixed seat 141. Loosen one of the nuts 144, then rotate the screw 143, and then tighten the other nut 144, so that the two nuts 144 can cooperate with the position of the positioning screw 143, so that the screw 143 can be stabilized on the fixed seat 141, and the screw 143 is prevented from loosening, so that the conveyor mesh belt 210 can wrap the pressure wheel 220, so that the conveyor mesh belt 210 can remain tensioned, which is convenient for stabilizing the position of the filter paper and improving the filtering effect of the cutting fluid.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
