Description

Technical Field

[0001] The invention relates to the technical field of cutting fluid recovery of precision engraving machines, in particular to a cutting fluid recovery box assembly for precision engraving machines. Background Art

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Formulated from a scientifically formulated combination of multiple highly functional additives, cutting fluid offers excellent cooling, lubrication, rust prevention, oil removal, cleaning, corrosion protection, and easy dilution. It overcomes the drawbacks of traditional soap-based emulsions, such as summer odor, difficulty in dilution in winter, and poor rust prevention. It also has no adverse effects on lathe finishes, making it suitable for the cutting and grinding of ferrous metals and a leading grinding product. Cutting fluid outperforms saponified oil in all aspects, offering excellent lubrication, cooling, cleaning, and rust prevention properties. It is also non-toxic, odorless, non-corrosive to humans, equipment, and the environment. Cutting fluid is essential for precision engraving machine operations and must be recycled after use.

[0003] During use, the existing cutting fluid recovery box assembly of the precision engraving machine recovers the cutting fluid into the recovery box, and drives the separation cylinder to rotate rapidly through the driving assembly to achieve separation between the cutting fluid and the metal fragments. However, during the rapid rotation, the metal fragments will be embedded in the various separation holes in the separation cylinder, which will cause the separation efficiency of the separation cylinder to gradually decrease after a period of use, and may even affect the separation effect, thereby making the cutting fluid recovery box assembly lack of use value. Summary of the Invention

[0004] The present invention discloses a cutting fluid recovery box assembly for a precision engraving machine, which aims to solve the technical problem that, during use, the existing cutting fluid recovery box assembly for a precision engraving machine recovers the cutting fluid into the recovery box, and drives the separation cylinder to rotate rapidly through the driving assembly, thereby realizing the separation between the cutting fluid and the metal fragments. However, during the rapid rotation, the metal fragments will be embedded in the various separation holes in the separation cylinder, which will cause the separation efficiency of the separation cylinder to gradually decrease after a period of use, and may even affect the separation effect.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cutting fluid recovery box assembly for a precision engraving machine includes a recovery box body, a water inlet assembly is provided on the top of the recovery box body; the interior of the recovery box body is provided with a primary filtering and recovering assembly, a secondary filtering and recovering assembly and a power drive assembly from top to bottom, and a separation auxiliary assembly is provided on the outside of the secondary filtering and recovering assembly.

[0007] The separation auxiliary component includes a supporting ring plate arranged on the outside of the power drive component, and an axle frame is distributed in an annular manner on the top of the supporting ring plate. The inner side of the axle frame is connected to a deflection shaft through a bearing, and the outer side of the deflection shaft is fixedly connected to a deflection arc plate. The outer side of the deflection arc plate facing the center point of the supporting ring plate is fixedly connected to an adaptive long rod through a telescopic component, and a semicircular impact ball is fixedly connected to the outer side of the adaptive long rod at equal distances, and a contact piece is fixedly connected to the outer side of the axle frame near the deflection arc plate, and a reset spring rod is provided at equal distances between the contact piece and the deflection arc plate.

[0008] The secondary filtration and recovery assembly includes a separation drum. The power drive assembly is located at the bottom of the separation drum. An electromagnetic roller is fixedly connected to the interior of the separation drum. A circulation groove is defined at the top of the electromagnetic roller. The electromagnetic roller is rotatably and slidably connected to the primary filtration and recovery assembly through the circulation groove. A torque sensor is located within the electromagnetic roller.

[0009] The circulation groove is trapezoidal after being unfolded.

[0010] Since an electromagnetic roller is provided inside the separation cylinder and is rotatably and slidingly connected to the primary filter recovery assembly through a circulation groove, the flow rate of water ejected from the separation cylinder is determined by detecting the torque of the electromagnetic roller per unit time and the compression of the return spring rod per unit time. Based on the flow rate, it is determined whether the secondary filter recovery assembly or the primary filter recovery assembly is clogged.

[0011] When the torque of the electromagnetic roller is large and the compression of the return spring rod is small, it indicates that the secondary filter recovery component is blocked. At this time, the separation auxiliary component controls the semicircular impact ball to impact the separation cylinder to eliminate the blockage;

[0012] When the torque of the electromagnetic roller is large and the compression of the return spring rod is large, it indicates that the primary filter recovery component is clogged;

[0013] At this time, the impact on the primary filtration and recovery components is increased by controlling the water inlet components to eliminate blockage.

[0014] Preferably, a blocking frame covering the primary filter recovery component and the secondary filter recovery component is provided inside the recovery box; and a drainage pipe penetrating the recovery box is provided at the bottom of the blocking frame.

[0015] A discharge pipe penetrating the recovery box is provided at the bottom of the separation cylinder.

[0016] By setting up a blocking frame, the separated cutting fluid will not be thrown out of the recovery box during the rotation of the separation cylinder. When the cutting fluid is separated, it is discharged from the drain pipe and the residue in the separation cylinder is discharged from the discharge pipe.

[0017] Preferably, the power drive assembly includes a movable rail fixedly connected to the bottom of the recovery box, a sliding block is slidably connected inside the movable rail, and limiting contact rods are provided on both sides of the sliding block, and the other ends of the two limiting contact rods are respectively fixedly connected to the ends of the movable rail.

[0018] The top of the sliding block is fixedly connected to the base plate, the top of the base plate is fixedly connected to the driving motor, the output shaft of the driving motor is fixedly connected to the driving shaft through a coupling, the top of the driving shaft is fixedly connected to the bottom of the separation cylinder, the top of the base plate located outside the driving motor is fixedly connected to an annular limiting rail, the inside of the annular limiting rail is equidistantly slidably connected to a rotating sliding rod, and each of the rotating sliding rods is fixedly connected to the bottom of the separation cylinder.

[0019] By setting a driving motor and a driving shaft, the driving motor can synchronously drive the separation drum to rotate during operation, so that the separation drum can centrifugally separate the cutting fluid; by setting an annular limiting rail and a rotating sliding rod, the driving motor can synchronously drive the rotating sliding rod to slide inside the annular limiting rail during the process of driving the separation drum to rotate, thereby improving the stability of the separation drum during rotation.

[0020] Preferably, the secondary filtration recovery assembly also includes a lower contact ring fixedly connected to the top of the separation cylinder, the top of the lower contact ring is rotatably connected to the upper contact ring, the top of the upper contact ring is fixedly connected to a guide cover, and the guide cover is located below the primary filtration recovery assembly and fixedly connected to the top of the recovery box.

[0021] By setting up a flow guide cover, the cutting fluid filtered and separated by the primary filter recovery component enters the interior of the separation cylinder through the flow guide cover. Since the lower contact ring above the separation cylinder is sealed and rotated with the upper contact ring at the bottom of the flow guide cover, the cutting fluid will not leak when passing through the flow guide cover.

[0022] Preferably, the primary filtration recovery component includes a foldable screen plate and a waste collection frame, the waste collection frame is fixedly connected to the outside of the recovery box, the foldable screen plate is located on the inside of the recovery box, and the outer side of the foldable screen plate facing downward is fixedly connected with a connecting plate.

[0023] A fixing cylinder is provided in the middle of the foldable screen plate, and a protrusion which is slidably connected to the circulation groove is fixedly connected to the inner wall of the fixing cylinder.

[0024] By arranging the protrusions and the circulation grooves, during the rotation of the electromagnetic roller, the protrusions and the circulation grooves on the foldable screen plate are squeezed against each other, thereby causing the foldable screen plate to reciprocate up and down. On the one hand, this reduces the accumulation of residue in the cutting fluid on the foldable screen plate. On the other hand, after the sieve holes on the foldable screen plate are blocked, the foldable screen plate reciprocates up and down and the water inlet assembly cooperates to cause the foldable screen plate to offset the cutting fluid entering the recovery box, thereby causing the residue blocked in the sieve holes of the foldable screen plate to be flushed away.

[0025] Preferably, the bottoms of the two connecting plates are fixedly connected with connecting spring rods at equal distances, and the other ends of the multiple connecting spring rods located on the same connecting plate are fixedly connected with the same mounting plate, and the two mounting plates are respectively fixedly connected to the inner wall of the recovery box below the feed end.

[0026] By providing a primary filtering and recovery component, when the cutting fluid is recovered, the cutting fluid falls from a high place onto the foldable screen plate, and the cutting fluid impacts the foldable screen plate, causing the connecting spring rod to be in an oscillating state, thereby accelerating the initial separation of the cutting fluid by the foldable screen plate. After the initial separation, the fragments remaining slide along the high place of the foldable screen plate to the groove, and the adsorption pump is started. The adsorption pump collects these fragments through the adsorption frame to prevent their accumulation and the cutting fluid from being unable to fall smoothly.

[0027] Preferably, the primary filtration recovery assembly further comprises an adsorption frame fixedly connected to the outer wall of the recovery box body and symmetrically arranged, the adsorption frame being provided with mounting holes, the mounting holes being located at two grooves on the recovery box body near the foldable screen plate.

[0028] Two adsorption pumps are fixedly connected to the top of the waste collection frame, and the adsorption ends of the two adsorption pumps are fixedly connected to connecting pipes. The other ends of the connecting pipes are inserted into the interior of the corresponding adsorption frame and connected to the mounting holes.

[0030] During the initial separation of the cutting fluid, the telescopic sleeve is stretched by adjusting the hydraulic cylinder so that the spray hood is at a higher position, making the height difference between the cutting fluid and the folding screen plate larger, thereby enhancing the effect of gravity impact and further improving the efficiency of the initial separation of the cutting fluid.

[0031] Preferably, two mounting rods are fixedly connected to one side of the recovery box, and the other ends of the two mounting rods are fixedly connected to the same extraction cover.

[0032] The outside of the recovery box is fixedly connected to an extraction pump, the extraction end of the extraction pump is fixedly connected to a long extraction tube, the other end of the long extraction tube is inserted into the interior of the extraction cover, and the delivery end of the extraction pump is fixedly connected to a long delivery tube, the other end of the long delivery tube is inserted into the interior of the liquid spray cover.

[0033] By providing a hydraulic cylinder, a telescopic sleeve and a liquid spray hood, when performing the preliminary separation of the cutting fluid, the telescopic sleeve is stretched by adjusting the hydraulic cylinder so that the liquid spray hood is in a higher position, making the height difference between the cutting fluid and the foldable screen plate larger, thereby improving the effect of gravity impact and further improving the efficiency of the preliminary separation of the cutting fluid.

[0034] Preferably, a door hole is opened on one side of the recycling box body, and the inner walls on both sides of the door hole are connected to the box door through hinges. The outer sides of the two doors are provided with door handles, and the same door buckle is inserted into the two door handles, and the outer sides of the contact points between the two doors and the recycling box body are provided with sealing rings.

[0035] Technical effects and advantages of the present invention:

[0036] 1. The present invention provides a separation cylinder and an auxiliary separation component. When the driving motor drives the separation cylinder to quickly rotate and separate the cutting fluid, an extrusion collision occurs between the rotating separation cylinder and the semicircular impact ball on the outside of the adapter long rod. During the collision, the semicircular impact ball produces an impact on the separation cylinder, causing it to vibrate, thereby shaking out the metal fragments embedded in the separation hole in the separation cylinder, preventing the embedding of metal fragments from causing a decrease in the separation effect and separation efficiency of the separation cylinder. At the same time, the semicircular impact ball is driven to the outside by the impact, and the deflection arc plate behind it is deflected, so that the reset spring rod is compressed. The reset effect of the reset spring rod drives the semicircular impact ball to repeatedly collide with the separation cylinder, thereby ensuring the technical effect of the separation effect and separation efficiency of the separation cylinder.

[0037] 2. The present invention sets an electromagnetic roller and a return spring rod, and determines the flow rate of water thrown out of the separation cylinder by detecting the torque of the electromagnetic roller and the compression of the return spring rod per unit time, and determines whether the secondary filter recovery component or the primary filter recovery component is blocked according to the flow rate; when the torque of the electromagnetic roller is large and the compression of the return spring rod is small, it indicates that the secondary filter recovery component is blocked. At this time, the separation auxiliary component controls the semicircular impact ball to impact the separation cylinder to eliminate the blockage; when the torque of the electromagnetic roller is large and the compression of the return spring rod is large, it indicates that the primary filter recovery component is blocked; at this time, the water inlet component is controlled to increase the impact on the primary filter recovery component to eliminate the blockage.

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] The cutting fluid recovery box assembly for a precision engraving machine disclosed in the present invention is mainly applied to the existing cutting fluid recovery box assembly for a precision engraving machine. During use, the cutting fluid is recovered into the recovery box, and the separation cylinder 401 is driven by the driving assembly to rotate rapidly, thereby realizing the separation between the cutting fluid and the metal fragments. However, during the rapid rotation, the metal fragments will be embedded in the various separation holes in the separation cylinder 401, which will cause the separation efficiency of the separation cylinder 401 to gradually decrease after a period of use, and may even affect the separation effect.

The inner side of each axis frame 602 is rotatably connected to a deflection shaft 603 through a bearing, and the outer side of the deflection shaft 603 is fixedly connected to a deflection arc plate 604, and the outer side of the deflection arc plate 604 facing the center point of the support ring plate 601 is fixedly connected to an adaptive long rod 605, and the outer side of the adaptive long rod 605 is fixedly connected to a semicircular impact ball 606 at an equal distance, and the outer side of the axis frame 602 near the deflection arc plate 604 is fixedly connected to a contact piece 607, and a reset spring rod 608 is equidistantly provided between the contact piece 607 and the deflection arc plate 604.

[0055] In a specific application scenario, when the driving motor 505 drives the separation cylinder 401 to quickly rotate and separate the cutting fluid, an extrusion collision occurs between the rotating separation cylinder 401 and the semicircular impact ball 606 on the outside of the adapter long rod 605. During the collision, the semicircular impact ball 606 produces an impact on the separation cylinder 401, causing it to vibrate, thereby shaking out the metal fragments embedded in the separation hole in the separation cylinder 401, preventing the embedding of metal fragments from causing a reduction in the separation effect and separation efficiency of the separation cylinder 401. At the same time, the semicircular impact ball 606 is driven to the outside by the impact, and the deflection arc plate 604 behind it is deflected, so that the reset spring rod 608 is compressed, and the reset effect of the reset spring rod 608 drives the semicircular impact ball 606 to repeatedly collide with the separation cylinder 401, ensuring the separation effect and separation efficiency of the separation cylinder 401.

[0056] Reference Figure 1 、 Figure 3 、 Figure 5 and Figure 6In a preferred embodiment, the top of the sliding block 502 is fixedly connected to the bottom plate 504, and the top of the bottom plate 504 is fixedly connected to the driving motor 505, the output shaft of the driving motor 505 is fixedly connected to the driving shaft 506 through a coupling, the top of the driving shaft 506 is fixedly connected to the separation cylinder 401, the separation cylinder 401 is in contact with each semicircular impact ball 606, the top of the bottom plate 504 located outside the driving motor 505 is fixedly connected to the annular limiting rail 507, the inside of the annular limiting rail 507, etc. The distance sliding connection is provided with a rotating sliding rod 508, each rotating sliding rod 508 is fixedly connected to the bottom of the separation cylinder 401, the top of the separation cylinder 401 is fixedly connected with a lower contact ring 404, and the recovery box 1 is provided with a primary filter recovery component 3 on the inner side of the open end, and the inner wall of the recovery box 1 below the primary filter recovery component 3 is fixedly connected with a guide cover 406, and the inner side of the guide cover 406 is fixedly connected with an upper contact ring 405, and the upper contact ring 405 and the lower contact ring 404 are sealed and rotatably connected.

[0057] Reference Figure 1 、 Figure 3 and Figure 8 The foldable screen plate 301 is located on the inner side of the recycling box 1, and the foldable screen plate 301 is in contact with the inner wall of the feeding end of the recycling box 1. The outer side of the foldable screen plate 301 facing downward is fixedly connected with a connecting plate 303. The bottoms of the two connecting plates 303 are fixedly connected with connecting spring rods 306 at equal distances, and the other ends of the multiple connecting spring rods 306 located on the same connecting plate 303 are fixedly connected with the same mounting plate 307. The two mounting plates 307 are respectively fixedly connected to the inner wall of the recycling box 1 below the feeding end. The primary filtering and recycling assembly 3 also includes an adsorption frame 308 fixedly connected to the outer wall of the recycling box 1 and symmetrically arranged. The adsorption frame 308 is provided with a mounting hole, which is located at two grooves on the recycling box 1 near the foldable screen plate 301.

[0058] Two adsorption pumps 309 are fixedly connected to the top of the waste collection frame 302. The adsorption ends of the two adsorption pumps 309 are fixedly connected to a connecting pipe 310. The other end of the connecting pipe 310 is inserted into the interior of the corresponding adsorption frame 308 and is connected to the mounting hole. The delivery ends of the adsorption pumps 309 are inserted into the interior of the waste collection frame 302 through pipes 311.

[0059] It should be noted that when the cutting fluid is being recovered, the cutting fluid falls from a high place onto the foldable screen plate 301, and the cutting fluid impacts the foldable screen plate 301, causing the connecting spring rod 306 to be in an oscillating state, thereby accelerating the foldable screen plate 301 to perform a preliminary separation of the cutting fluid. After the preliminary separation, the remaining fragments slide down the high place of the foldable screen plate 301 to the groove, and the adsorption pump 309 is started. The adsorption pump 309 collects these fragments through the adsorption frame 308 to prevent their accumulation and the cutting fluid from being unable to fall smoothly.

[0060] Reference Figure 2 and Figure 4 In a preferred embodiment, door handles 8 are provided on the outside of the two doors, and the same door buckle is plugged into the two door handles 8, and sealing rings are provided on the outside of the contact points between the two doors and the recovery box body 1.

[0061] Reference Figure 1 and Figure 9 In a preferred embodiment, the top of the recovery box 1 at the open end is fixedly connected to a telescopic sleeve 201, and the outer side of the telescopic sleeve 201 near the top is fixedly connected to an outer ring frame 202, the top of the telescopic sleeve 201 is fixedly connected to a liquid spray cover 203, and the outer side of the recovery box 1 below the outer ring frame 202 is fixedly connected to two hydraulic cylinders 204, and the output ends of the two hydraulic cylinders 204 are fixedly connected to the bottom of the outer ring frame 202.

[0062] Specifically, when performing the initial separation of the cutting fluid, the telescopic sleeve 201 is stretched by adjusting the hydraulic cylinder 204 so that the spray hood 203 is at a higher position, making the height difference between the cutting fluid and the foldable screen plate 301 larger, thereby improving the effect of gravity impact and further improving the efficiency of the initial separation of the cutting fluid.

[0063] Reference Figure 2 In a preferred embodiment, two mounting rods 205 are fixedly connected to one side of the recovery box 1, and the other ends of the two mounting rods 205 are fixedly connected to the same extraction cover 206, and an extraction pump 207 is fixedly connected to the outside of the recovery box 1, and the extraction end of the extraction pump 207 is fixedly connected to an extraction long tube 208, and the other end of the extraction long tube 208 is inserted into the interior of the extraction cover 206, and the delivery end of the extraction pump 207 is fixedly connected to a delivery long tube 209, and the other end of the delivery long tube 209 is inserted into the interior of the liquid spray cover 203.

[0064] Working principle: When in use, start the extraction pump 207, and the extraction pump 207 guides the cutting fluid on the engraving machine into the spray cover 203 through the extraction cover 206, and then sprays it to the primary filter recovery component 3 through the spray cover 203. The cutting fluid impacts the folding screen plate 301, so that the connecting spring rod 306 is in an oscillating state, which accelerates the folding screen plate 301 to perform preliminary separation of the cutting fluid. After the preliminary separation, the metal residue retained slides down the high point of the folding screen plate 301 to the groove, and the adsorption pump 309 is started. The adsorption pump 309 collects the fragments through the adsorption frame 308. The cutting fluid after preliminary separation enters the separation cylinder 401 through the guide cover 406, and the driving motor 505 drives the separation cylinder 401 to rotate and separate the cutting fluid rapidly. When the separation cylinder 401 is rotating, an extrusion collision occurs with the semicircular impact ball 606 on the outside of the adapter long rod 605. During the collision, the semicircular impact ball 606 produces an impact on the separation cylinder 401, causing it to vibrate, thereby shaking out the metal slag embedded in the separation hole of the separation cylinder 401, preventing the embedding of metal slag from causing a decrease in the separation effect and separation efficiency of the separation cylinder 401. At the same time, the semicircular impact ball 606 is driven to the outside by the collision, and the deflection arc plate 604 behind it is deflected, so that the reset spring rod 608 is compressed, and the reset effect of the reset spring rod 608 drives the semicircular impact ball 606 to repeatedly collide with the separation cylinder 401. The separated cutting fluid is discharged from the drain pipe on the recovery box 1, and the staff collects it.

[0065] Example 2

[0066] Although the above embodiment can improve the separation effect of the cutting fluid to a certain extent, the metal slag stuck in the separation hole will have two situations during the process of the separation auxiliary component 6 impacting the separation cylinder 401. One is to return to the separation cylinder 401; the other is to fall to the outside of the separation cylinder 401, thereby causing the separation effect of the cutting fluid to decrease; because the metal slag will also be stuck in the sieve holes on the folding screen plate 301, and because the spray hood 203 sprays the cutting fluid toward the folding screen plate 301 continuously and uninterruptedly, the connecting spring rod 306 is consistently in a compressed state, and cannot generate vibrations of sufficient amplitude, and thus cannot shake off the metal slag stuck in the sieve holes of the folding screen plate 301, causing the folding screen plate 301 to be blocked. In view of this, improvements are made on the basis of embodiment 1, and the improved technical solution is as follows.

[0071] Since an electromagnetic roller 402 is provided inside the separation cylinder 401, and the electromagnetic roller 402 is rotatably and slidingly connected to the primary filter recovery component 3 through the circulation groove 403; during operation, the torque of the electromagnetic roller 402 per unit time and the compression amount of the return spring rod 608 per unit time are detected to determine the flow rate of the water thrown out of the separation cylinder 401, and based on the flow rate, it is determined whether the secondary filter recovery component 4 or the primary filter recovery component 3 is blocked.

[0072] When the torque of the electromagnetic roller 402 is large and the compression of the return spring rod 608 is small, it indicates that the secondary filtration recovery component 4 is blocked. At this time, the semicircular impact ball 606 is controlled by the separation auxiliary component 6 to impact the separation cylinder 401 to eliminate the blockage.

[0073] When the torque of the electromagnetic roller 402 is large and the compression amount of the return spring rod 608 is large, it indicates that the primary filter recovery component 3 is clogged.

[0074] At this time, the water inlet component 2 is controlled to increase the impact on the primary filtering and recovery component 3 to eliminate blockage.

[0075] Preferably, the primary filtration recovery component 3 includes a foldable screen plate 301 and a waste collection frame 302. The waste collection frame 302 is fixedly connected to the outside of the recovery box 1. The foldable screen plate 301 is located on the inside of the recovery box 1. The outer side of the foldable screen plate 301 facing downward is fixedly connected with a connecting plate 303.

[0076] A fixed cylinder 304 is provided in the middle of the foldable screen plate 301 , and a protrusion 305 which is slidably connected to the circulation groove 403 is fixedly connected to the inner wall of the fixed cylinder 304 .

[0077] By setting the protrusion 305 and the circulation groove 403, during the rotation of the electromagnetic roller 402, the protrusion 305 and the circulation groove 403 on the foldable screen plate 301 are squeezed against each other, thereby causing the foldable screen plate 301 to reciprocate up and down. On the one hand, this reduces the accumulation of residue in the cutting fluid on the foldable screen plate 301. On the other hand, after the sieve holes on the foldable screen plate 301 are blocked, the foldable screen plate 301 reciprocates up and down and cooperates with the water inlet component 2, so that the foldable screen plate 301 and the cutting fluid entering the recovery box 1 are offset, thereby causing the residue blocked in the sieve holes of the foldable screen plate 301 to be washed away.

[0078] A control terminal is provided on the outside of the recycling box 1, and a control system is provided on the inside of the control terminal. The control system is used to control all electrical components on the recycling box 1 and control and adjust the electrical components; the telescopic component includes an electromagnetic plug and an electric push rod.

[0079] In the initial state, the electromagnetic roller 402 inside the separation cylinder 401 is not energized and does not have magnetism; the telescopic assembly is in a retracted state; the protrusion 305 on the fixed cylinder 304 is located at the bottom of the circulation groove 403 (specifically, Figure 12 As shown), the hydraulic cylinder 204 on the outer ring frame 202 is in a retracted state.

[0080] During use, the control system controls the extraction pump 207 to operate, so that the extraction pump 207 extracts the unfiltered and separated cutting fluid through the extraction long tube 208 and the extraction cover 206, and then transports the unfiltered and separated cutting fluid to the inside of the spray cover 203 on the top of the recovery box 1 through the delivery long tube 209. The spray cover 203 sprays the unfiltered and separated cutting fluid downward. The unfiltered and separated cutting fluid is first filtered and recovered by the primary filter recovery component 3, so that the large particles of metal slag in the unfiltered and separated cutting fluid can be eliminated; then it is centrifuged through the secondary filter recovery component 4, so that the small particles of metal slag in the unfiltered and separated cutting fluid can be eliminated. The cutting fluid after centrifugal separation by the secondary filter recovery component 4 is discharged from the drain pipe 7, thereby completing the recovery of the cutting fluid.

[0081] While the control system controls the extraction pump 207 to work, the control system also controls the electromagnetic roller 402 to be energized and the drive motor 505 to operate (the longer the drive motor 505 runs, the greater the current supplied to the electromagnetic roller 402, and the greater the magnetic attraction generated). During the operation of the drive motor 505, the drive shaft 506 on the drive motor 505 synchronously drives the separation cylinder 401 and the electromagnetic roller 402 to rotate. Since the foldable screen plate 301 is slidingly connected to the circulation groove 403 on the electromagnetic roller 402 through the protrusion 305 on the fixed cylinder 304, and since both ends of the foldable screen plate 301 are fixedly connected to the top of the connecting spring rod 306 through the connecting plate 303, when the drive motor 505 drives the separation cylinder 401 and the electromagnetic roller 402 to rotate, the circulation groove 403 on the electromagnetic roller 402 is squeezed with the protrusion 305, thereby causing the foldable screen plate 301 to move up and down. At this time, the connecting spring rod 306 plays a limiting role.

[0082] like Figure 12 As shown, when the bump 305 on the foldable screen plate 301 runs at the bottom of the circulation groove 403, the torque of the electromagnetic roller 402 monitored by the control system is the torque when the driving motor 505 drives the separation cylinder 401 to rotate; at this time, the torque monitored by the control system is set to S1.

[0083] When the bump 305 on the foldable screen plate 301 is operating in the lifting section of the circulation groove 403, the torque of the electromagnetic roller 402 monitored by the control system is the sum of the torque of the drive motor 505 driving the separation drum 401 to rotate and the torque of the circulation groove 403 on the electromagnetic roller 402 driving the foldable screen plate 301 to rise. The torque monitored by the control system is set to S2. When the value of S2 is detected to be greater than the set value, the control system activates the adsorption pump 309, which collects the metal slag on the foldable screen plate 301 through the adsorption frame 308.

[0084] When the bump 305 on the foldable screen plate 301 runs on the top of the circulation groove 403, the torque of the electromagnetic roller 402 monitored by the control system is the torque when the driving motor 505 drives the separation cylinder 401 to rotate plus the torque when the driving motor 505 rotates with the load of the foldable screen plate 301; at this time, the torque monitored by the control system is set to S3.

[0085] When the bump 305 on the foldable screen plate 301 runs in the descending section of the circulation groove 403, the torque of the electromagnetic roller 402 monitored by the control system is the sum of the torque when the driving motor 505 drives the separation cylinder 401 to rotate plus the torque when the circulation groove 403 on the electromagnetic roller 402 drives the foldable screen plate 301 to descend; at this time, the torque monitored by the control system is set to S4.

[0086] The electromagnetic roller 402 rotates one circle per unit time, and the value of the torque sensor inside the electromagnetic roller 402 detected by the control system per unit time is set to S.

[0087] After the unfiltered cutting fluid enters the interior of the separation cylinder 401, as the driving motor 505 drives the separation cylinder 401 to rotate, the separation cylinder 401 performs centrifugal filtration on the cutting fluid, and the cutting fluid thrown out of the separation cylinder 401 collides with the deflection arc plate 604. Since the deflection arc plate 604 is fixedly connected to the deflection shaft 603, the deflection shaft 603 is rotatably connected to the shaft frame 602, and the deflection arc plate 604 is connected to the contact piece 607 on the shaft frame 602 through the return spring rod 608, after the cutting fluid collides with the deflection arc plate 604, the deflection arc plate 604 drives the deflection shaft 603 to deflect on the shaft frame 602, and the deflection arc plate 604 squeezes the return spring rod 608 to cause it to undergo elastic deformation. By detecting the reading of the torque sensor in the electromagnetic roller 402 and the deformation of the return spring rod 608, it is determined whether the folding screen plate and the separation cylinder 401 are blocked.

[0088] When the control system detects that the reading S of the torque sensor in the electromagnetic roller 402 per unit time is greater than the set value, and the deformation of the reset spring rod 608 is in a normal state, it indicates that the separation hole on the surface of the separation cylinder 401 is not blocked, or the blockage in the separation hole does not cause too much impact; the sieve holes on the folding screen plate are blocked, causing the values ​​of S1, S2, and S3 to increase; at this time, the control system controls the hydraulic cylinder 204 to extend, and the telescopic end of the hydraulic cylinder 204 drives the spray cover 203 to move up through the outer ring frame 202, thereby causing the spray cover 203 and the folding screen plate to move upward. The distance between them increases; when the protrusion 305 runs to the lifting section of the circulation groove 403, the control system controls the telescopic end of the hydraulic cylinder 204 to shrink rapidly. Since the protrusion 305 runs to the lifting section of the circulation groove 403, the folding screen plate is in an upward running state, which causes the unfiltered and unseparated cutting fluid to collide strongly with the folding screen plate, causing the folding screen plate 301 to collide with the cutting fluid entering the recovery box 1, thereby causing the residue blocked in the sieve holes of the folding screen plate 301 to be washed off, and the metal residue stuck in the folding screen plate to enter the separation cylinder 401.

[0089] When the control system detects that the reading S of the torque sensor in the electromagnetic roller 402 per unit time is greater than the set value, and the deformation of the reset spring rod 608 is less than the set value, it indicates that the sieve holes on the folding screen plate are not blocked, or the blockage in the sieve holes does not cause too much impact; the separation holes on the surface of the separation cylinder 401 are blocked, so that the cutting fluid thrown out of the separation cylinder 401 cannot cause a sufficiently large impact force with the deflection arc plate 604, so that the value of S increases. At this time, the control system controls the telescopic component to continuously perform telescopic movement. When the telescopic component is extended, it drives the adapter long rod 605 and the semicircular impact ball 606 to separate. The surface of the cylinder 401 moves, causing the semicircular impact ball 606 to squeeze and collide with the surface of the separation cylinder 401. During the collision, the semicircular impact ball 606 produces an impact on the separation cylinder 401, causing it to vibrate, thereby vibrating out the metal fragments embedded in the separation holes in the separation cylinder 401; because the electromagnetic roller 402 inside the separation cylinder 401 is in an energized state at this time, the metal fragments are shaken out and then, under the influence of the magnetic force of the electromagnetic roller 402, return to the inside of the separation cylinder 401, preventing the embedding of metal fragments from reducing the separation effect and separation efficiency of the separation cylinder 401, thereby ensuring the separation effect and separation efficiency of the separation cylinder 401.
