Description

Technical Field

[0001] This invention belongs to the field of machining center technology, specifically a chip handling device for CNC. Background Technology

[0002] CNC stands for "Computer Numerical Control," commonly known as "numerical control." It is an automated machine tool controlled by a computer. It effectively solves the problem of machining complex, precise, small-batch, and multi-variety parts. It is a high-efficiency automated machine tool and represents the development direction of modern machine tool control technology. Unlike ordinary machine tools, it does not require the manufacture or replacement of many molds and fixtures, nor does it require frequent readjustment of the machine tool. It processes raw materials into semi-finished and finished parts through cutting tools. During the machining process, the cutting tools generate a large amount of debris that adheres to the worktable or workpiece surface. At the same time, cutting fluid is needed to cool and lubricate the cutting tools.

[0003] Cutting fluid is a scientifically formulated blend of multiple high-performance additives. It possesses excellent cooling, lubrication, rust prevention, degreasing and cleaning, corrosion protection, and easy dilution properties. Without cutting fluid, machine tools and workpieces are prone to deformation and rust at high temperatures. Therefore, cutting fluid must be used during machining to prevent these problems. When using cutting fluid, it carries away debris adhering to the worktable or workpiece surface. The cutting fluid mixed with the debris is collected by a specific device for further recycling.

[0004] Because the cutting fluid carries debris into the recovery unit, a large amount of particulate matter and mixed oil will be introduced, along with the growth and reproduction of microorganisms. This will cause the cutting fluid to become ineffective, discolored, and smelly, losing its lubricating, cooling, rust-preventing, and cleaning functions. This will affect the machining quality, damage the cutting tool, and pose occupational health hazards. It is necessary to replace the cutting fluid or take effective measures to separate the cutting fluid from the debris.

[0005] Currently, membrane separation technology and oxidation-reduction method are generally used for the treatment and recycling of cutting fluid. Membrane separation technology has the advantages of high efficiency, small footprint, and no secondary pollution, but membrane fouling problem limits the large-scale application of membrane filtration technology. Oxidation-reduction method can oxidize the contaminants in cutting fluid into harmless inorganic substances, but it will also destroy the effective components in cutting fluid, which is not conducive to the secondary utilization of cutting fluid.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The chip handling device for CNC machining described in this invention, when cutting fluid passes through the inside of a first sleeve and a second sleeve, the first and second sleeves cooperate to filter chips in the cutting fluid whose diameter is smaller than the diameter of the first and second drain holes. Simultaneously, by rotating the second sleeve within the first sleeve at different angles in a multi-set filtration device, the size of the gap formed by the alternating first and second drain holes can be adjusted. Chips with a diameter larger than this gap cannot pass through, thus achieving layer-by-layer filtration of chips of different diameters, significantly enhancing the filtration capacity for smaller chips in the cutting fluid. When excessive chips accumulate in the second sleeve, it affects the flow of cutting fluid within the second sleeve, causing… When the cutting fluid begins to flow along the outer surface of the first sleeve, the interception hooks on the outer surface of the first sleeve can intercept the curled debris in the cutting fluid, allowing the fine debris to continue flowing along the surface of the cutting fluid into the next set of first and second sleeves. This prevents some curled debris from also entering the next second sleeve and causing blockage, thereby enhancing the overall filtration effect of the filtration device on debris in the cutting fluid, improving the filtration efficiency of debris, separating debris from the cutting fluid, reducing the mixing of particulate matter in the cutting fluid, reducing the attachment of microorganisms, and thus reducing the growth and reproduction of microorganisms. At the same time, the use of physical separation methods avoids the deactivation of effective components in the cutting fluid, which is conducive to the recycling and reuse of the cutting fluid.

[0020] 2. The chip handling device for CNC described in this invention controls the angle between the trapezoidal plate and the horizontal guide plate to create a turbulent flow of the cutting fluid containing chips. This prevents fine chips from accumulating on the left side of the trapezoidal plate, allowing them to enter the next set of first and second sleeves for batch filtration. The evenly distributed, denser trapping hooks on the trapezoidal plate can trap even smaller, curled chips. Furthermore, by controlling the angle between the trapezoidal plate and the horizontal guide plate, the turbulent flow effect of the trapezoidal plate on the cutting fluid can be adjusted according to the flow rate.

[0021] 3. The chip handling device for CNC described in this invention, due to the trapezoidal plate and the horizontal guide plate forming a certain angle, and the filter hole and the horizontal guide plate also forming a certain angle, when the cutting fluid flows into the filter hole, because the top of the filter hole faces the cutting fluid, some of the cutting fluid will directly flow into the filter hole, thereby allowing some of the chips in the cutting fluid to also flow directly into the filter hole. Under the action of the cutting fluid flow, the filter bag's ability to filter chips is enhanced, thereby improving the filtration efficiency of chips in the cutting fluid.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] like Figures 1 to 15 As shown, the present invention demonstrates a chip handling device for CNC, which is specifically as follows;

[0041] The box includes a housing 1, which is composed of six panels. Besides the top and bottom panels, the other four panels are labeled A11, B12, C13, and D14. A liquid inlet 111 is located at the top of A11. Two first mounting brackets 15 are fixedly installed on the opposite side of D14 from B12. Two second mounting brackets 16 are fixedly installed on the opposite side of B12 from D14. The second mounting brackets 16 are cylindrical. The first mounting brackets 15 slide within the second mounting brackets 16. B12 can slide along the cavity formed by A11, C13, the top panel, and the bottom panel, along with the second mounting brackets 16. Rectangular mounting brackets 17 are fixedly installed on each of the second mounting brackets 16. A flow guiding device 2 is installed on both rectangular mounting brackets 17. The flow guiding device 2 includes several horizontal flow guiding plates 21 and inclined flow guiding plates 22; the horizontal flow guiding plates 21 are arranged in a stepped manner from top to bottom; an inclined flow guiding plate 22 is fixedly connected between each pair of adjacent horizontal flow guiding plates 21; two rectangular mounting brackets 17 are fixedly connected to the bottom of the adjacent horizontal flow guiding plates 21; baffles 24 are fixedly connected to both sides of the horizontal flow guiding plates 21 and inclined flow guiding plates 22; the upper surface of the horizontal flow guiding plate 21 near the liquid outlet 131 is flush with the bottom of the liquid inlet 111; the bottom of the C plate 13 has a liquid outlet 131; the upper surface of the horizontal flow guiding plate 21 near the liquid outlet 131 is flush with the bottom of the liquid outlet 131; each inclined flow guiding plate 22 has evenly arranged semi-circular grooves 26; a filter device 3 is installed in each semi-circular groove 26.

[0042] Each filter device 3 includes a first sleeve 31 and a second sleeve 35; the first sleeve 31 has a semi-circular cross-section; the second sleeve 35 has a circular cross-section; the second sleeve 35 passes through the baffle 24 near the B plate 12 and is installed in a semi-circular groove 26; the second sleeve 35 is slidably connected to the baffle 24 near the B plate 12; the second sleeve 35 can rotate and slide within the semi-circular groove 26; the first sleeve 31 is fitted onto the outer surface of the second sleeve 35, and the outer surface of the second sleeve 35 is in contact with the inner surface of the first sleeve 31; the first sleeve 31 is mounted on the inclined guide plate 22; a first liquid inlet groove is provided on the side of the first sleeve 31 near the A plate 11. 32; The first sleeve 31 has uniformly arranged first leakage holes 33 on the side away from plate A 11; the outer surface of the first sleeve 31 between the first liquid inlet groove 32 and the first leakage hole 33 is fixedly installed with uniformly arranged intercepting hooks 5; the second sleeve 35 has a second liquid inlet groove 36 on the side close to plate A 11; the second sleeve 35 has a uniformly arranged second leakage hole 37 on the side away from plate A 11; the first liquid inlet groove 32 and the second liquid inlet groove 36 have the same size; the first leakage hole 33 and the second leakage hole 37 have the same diameter; the first liquid inlet groove 32 coincides with the second liquid inlet groove 36 in the initial state; the first leakage hole 33 coincides with the second leakage hole 37 in the initial state.

[0043] Telescopic rotary cylinders 121 are fixedly installed on plate B 12 and are evenly arranged, extending into the housing 1; the positions of the telescopic rotary cylinders 121 correspond one-to-one with the positions of the second sleeve 35; the output ends of the telescopic rotary cylinders 121 are connected to the end of the second sleeve 35 near plate B 12 via couplings; the output ends of the telescopic rotary cylinders 121 are initially in an extended state.

[0044] When the CNC machining center is working, the used cutting fluid mixed with chips is pumped into the inlet 111 by an external water pump. After entering the housing 1 from the inlet 111, the cutting fluid mixed with chips flows along the surface of the horizontal guide plate 21, which is flush with the bottom of the inlet 111. As the cutting fluid containing chips continues to flow in, it gradually flows onto the inclined guide plate 22 connected to the horizontal guide plate 21. During the flow of the cutting fluid containing chips onto the inclined guide plate 22, the cutting fluid on the inclined guide plate 22... The filter device 3 filters the debris mixed in the cutting fluid. Since multiple filter devices 3 are arranged on each inclined guide plate 22, the cutting fluid will be filtered multiple times. Then the cutting fluid containing debris continues to flow to the next horizontal guide plate 21 and the inclined guide plate 22, and so on. Finally, the cutting fluid flows to the horizontal guide plate 21 that is flush with the outlet 131. At this time, the cutting fluid has been filtered layer by layer. The filtered cutting fluid is discharged from the outlet 131 for easy recycling and subsequent treatment.

[0045] Specifically, when cutting fluid containing debris enters the filter device 3, initially, the first inlet groove 32 on the first sleeve 31 and the second inlet groove 36 on the second sleeve 35 are completely overlapped, as are the first drain hole 33 on the first sleeve 31 and the second drain hole 37 on the second sleeve 35. Some of the cutting fluid containing debris will flow into the first inlet groove 32 on the first sleeve 31. Since the outer surface of the second sleeve 35 is in contact with the inner surface of the first sleeve 31 and the first inlet groove 32 and the second inlet groove 36 are completely overlapped, the cutting fluid containing debris will flow into the second inlet groove 36 on the second sleeve 35 and enter the interior of the second sleeve 35. As the cutting fluid containing debris continuously flows into the interior of the second sleeve 35, the level of the cutting fluid in the second sleeve 35 continuously rises. When the level of the cutting fluid in the second sleeve 35 is high... When the cutting fluid flows through the second drain hole 37 on the second sleeve 35, under the action of gravity, the cutting fluid will flow from the second drain hole 37 on the second sleeve 35 into the first drain hole 33 on the first sleeve 31, and then flow out from the first drain hole 33. During the process of the cutting fluid flowing out from the second drain hole 37 and the first drain hole 33, the debris in the cutting fluid will move with the flow of the cutting fluid. When the debris flows to the second drain hole 37, due to the limitation of the diameter of the second drain hole 37, the debris with a diameter larger than the diameter of the second drain hole 37 cannot pass through the second drain hole 37, so that this part of the debris remains in the second sleeve 35, thereby completing the separation and filtration of this part of the debris. The cutting fluid flowing out from the first drain hole 33 will continue to flow along the inclined guide plate 22 and enter the first inlet groove 32 on the next first sleeve 31, thus circulating.

[0046] Meanwhile, as the cutting fluid containing debris continuously flows into the second sleeve 35, the amount of debris filtered in the second sleeve 35 also increases. As the debris accumulates in the second sleeve 35, the space inside the second sleeve 35 gradually decreases. The accumulated debris gradually blocks the second drain hole 37, causing the flow rate of cutting fluid from the second drain hole 37 to gradually decrease. After the second sleeve 35 is filled with debris, the cutting fluid begins to flow along the upper surface of the first sleeve 31. At this time, the interception hooks 5 evenly arranged on the upper surface of the first sleeve 31 will hook and intercept the curled debris, thereby separating and filtering this part of the debris. The filtered cutting fluid still contains fine debris and flows to the inclined guide plate 22 and then flows into the first inlet groove 32 on the next first sleeve 31, thus circulating.

[0047] Furthermore, since the end of the second sleeve 35 near plate B 12 is connected to the output end of the telescopic rotary cylinder 121 via a coupling, controlling the rotation of the output end of the telescopic rotary cylinder 121 drives the second sleeve 35 to rotate within the semi-circular groove 26. Initially, the first liquid inlet groove 32 on the first sleeve 31 and the second liquid inlet groove 36 on the second sleeve 35 are completely overlapped, as are the first drain hole 33 on the first sleeve 31 and the second drain hole 37 on the second sleeve 35. When the second sleeve 35 rotates a certain angle, the first sleeve 31 and the second sleeve 35 will intersect, thus allowing the first liquid inlet groove on the first sleeve 31 to rotate. The second liquid inlet grooves 36 on the groove 32 and the second sleeve 35 are partially intersected, and the first drain hole 33 on the first sleeve 31 and the second drain hole 37 on the second sleeve 35 are also partially intersected. When cutting fluid containing debris enters the first drain hole 33 through the second drain hole 37, the partial intersecting of the second and first drain holes prevents debris with a diameter larger than the gap between them from passing through. This allows for the separation and filtration of smaller diameter debris. It is understood that the maximum angle of rotation of the second sleeve 35 on the semi-circular groove 26 will not cause the first and second liquid inlets 111 to completely intersect. Meanwhile, the second drain hole 37 and the first drain hole 33 will not be completely intersected. Therefore, when filtering cutting fluid containing debris, the operator will adjust the degree of overlap between the first sleeve 31 and the second sleeve 35 from top to bottom, gradually increasing the degree of overlap. This causes the gap formed by the intersecting first drain hole 33 and the second drain hole 37 to gradually decrease from top to bottom. Thus, when cutting fluid containing debris flows from top to bottom through multiple sets of first sleeves 31 and second sleeves 35, the gap formed by the gradually intersecting first drain hole 33 and the second drain hole 37 can be filtered according to the size of the debris. That is, when the cutting fluid contains debris flows from top to bottom through multiple sets of first sleeves 31 and second sleeves 35, the gap formed by the gradually intersecting first drain hole 33 and the second drain hole 37 can be filtered according to the size of the debris. The liquid flows into the uppermost first sleeve 31 and second sleeve 35. At this time, the first drain hole 33 and the second drain hole 37 can filter out debris larger than the gap between the first drain hole 33 and the second drain hole 37. Debris smaller than the diameter of the first drain hole 33 and the second drain hole 37 will flow out from the first drain hole 33 and the second drain hole 37 and then enter the next set of first sleeve 31 and second sleeve 35. Due to the gradually decreasing gap formed by the alternating first drain hole 33 and the second drain hole 37, the debris can be filtered in batches according to the size of the debris, thereby enhancing the filtration degree of debris in the cutting fluid and further reducing the debris content in the cutting fluid.

[0048] In this process, when the cutting fluid passes through the inside of the first sleeve 31 and the second sleeve 35, the first sleeve 31 and the second sleeve 35 cooperate with each other to filter debris in the cutting fluid whose diameter is smaller than the aperture of the first drain hole 33 and the second drain hole 37. Simultaneously, by rotating the second sleeve 35 within the first sleeve 31 at different angles in the multi-set filtration device 3, the size of the gap formed by the alternating first drain hole 33 and the second drain hole 37 can be adjusted. Debris with a diameter larger than this gap cannot pass through, thus achieving layer-by-layer filtration of debris of different diameters. This greatly enhances the filtration capacity for smaller debris in the cutting fluid. However, when too much debris accumulates in the second sleeve 35, it affects the flow of the cutting fluid within the second sleeve 35, causing the cutting fluid to... When the cutting fluid begins to flow along the outer surface of the first sleeve 31, the interception hooks 5 on the outer surface of the first sleeve 31 can intercept the curled debris in the cutting fluid, allowing the fine debris to continue flowing along the surface of the cutting fluid and enter the next set of first sleeves 31 and second sleeves 35. This prevents some curled debris from also entering the next second sleeve 35 and causing blockage, thereby enhancing the overall filtration effect of the filter device 3 on the debris in the cutting fluid, improving the filtration efficiency of the debris, separating the debris from the cutting fluid, reducing the mixing of particulate matter in the cutting fluid, reducing the attachment of microorganisms, and thus reducing the growth and reproduction of microorganisms. At the same time, the use of physical separation methods avoids the failure of effective components in the cutting fluid, which is conducive to the recycling and reuse of the cutting fluid.

[0049] In a specific embodiment, a U-shaped plate 46 is fixedly installed on the lower surface of the horizontal guide plate 21 on the right side of the inclined guide plate 22; a trapezoidal plate 4 is provided on the horizontal guide plate 21 above the U-shaped plate 46; a uniformly arranged intercepting hook 5 is also fixedly installed on the upper surface of the trapezoidal plate 4, and the density of the intercepting hook 5 is greater than the density of the intercepting hook 5 on the first sleeve 31; a rotating groove 41 is opened on the left side of the trapezoidal plate 4 at the bottom of the trapezoidal plate 4; a rotating shaft 42 is provided in the rotating groove 41; the two ends of the rotating shaft 42 are respectively fixedly connected to the baffles 24 on both sides; the rotating groove 41 and the rotating shaft 42 are rotatably connected; a rubber flow-blocking component 47 is fixedly installed on the horizontal guide plate 21 on the left side of the trapezoidal plate 4; the right side surface of the rubber flow-blocking component 47 is in contact with the left side of the trapezoidal plate 4.

[0050] The bottom surface of the trapezoidal plate 4 is provided with a sliding groove 48; the horizontal guide plate 21 on the right side of the inclined guide plate 22 is provided with a bottom hole 27; a first cylinder 45 is fixedly installed on the U-shaped plate 46; the output end of the first cylinder 45 passes through the bottom hole 27, and the output end is rotatably connected to a slider 49; the slider 49 slides in the sliding groove 48; the lower surface of the trapezoidal plate 4 is initially in contact with the upper surface of the horizontal guide plate 21.

[0051] When the cutting fluid containing debris passes through the horizontal guide plate 21, the cutting fluid will flow through the trapezoidal plate 4 on the horizontal guide plate 21. The trapezoidal plate 4 has a higher density of interception hooks 5 evenly arranged to intercept the slightly curled debris in the cutting fluid, thereby separating this part of the debris from the cutting fluid and enhancing the filtration effect. Then the cutting fluid continues to flow to the inclined guide plate 22 connected to the right side of the horizontal guide plate 21, and so on.

[0052] Specifically, when it is necessary to filter and separate debris from the cutting fluid, the output end of the first cylinder 45 gradually extends, and the slider 49, which is rotatably connected to the output end, slides within the groove 48 at the bottom of the trapezoidal plate 4. Since the left side of the trapezoidal plate 4 is rotatably connected to the rotating shaft 42, the right side of the trapezoidal plate 4 gradually tilts upwards, creating a certain angle between the trapezoidal plate 4 and the horizontal guide plate 21. When the cutting fluid flows along the surface of the trapezoidal plate 4, the tilted trapezoidal plate 4 creates turbulence, preventing fine debris from accumulating in the space above the horizontal guide plate 21 on the left side of the trapezoidal plate 4. This allows the debris to flow with the cutting fluid into the second sleeve 35 below for sequential filtration. Because the right surface of the rubber flow-blocking component 47 is in contact with the left side of the trapezoidal plate 4, it prevents... The cutting fluid is prevented from flowing over the bottom surface of the trapezoidal plate 4, thus reducing the turbulence effect of the trapezoidal plate 4 on the cutting fluid. The operator can adjust the angle between the trapezoidal plate 4 and the horizontal guide plate 21 as needed, so as to adjust the turbulence effect of the trapezoidal plate 4 on the cutting fluid in real time according to the flow rate of the cutting fluid. That is, when the flow rate of the cutting fluid is large, the angle between the trapezoidal plate 4 and the horizontal guide plate 21 is increased, thereby enhancing the turbulence effect on the cutting fluid. When the flow rate of the cutting fluid is small, the angle between the trapezoidal plate 4 and the horizontal guide plate 21 is decreased to prevent the angle between the trapezoidal plate 4 and the horizontal guide plate 21 from being too large and affecting the flow of the cutting fluid. After the cutting fluid is filtered, the output end of the first cylinder 45 gradually contracts, the slider 49 slides in the groove 48 in the initial direction, and at the same time, the trapezoidal plate 4 gradually returns to the horizontal state, and the lower surface of the trapezoidal plate 4 is in contact with the upper surface of the horizontal guide plate 21.

[0053] During this process, by controlling the angle between the trapezoidal plate 4 and the horizontal guide plate 21, the trapezoidal plate 4 can turbulently flow the cutting fluid containing debris, preventing fine debris from accumulating on the left side of the trapezoidal plate 4. This allows the debris to enter the next set of first sleeves 31 and second sleeves 35 with the cutting fluid for sequential filtration in batches. The denser trapezoidal hooks 5 evenly arranged on the trapezoidal plate 4 can trap even smaller curled debris. At the same time, by controlling the angle between the trapezoidal plate 4 and the horizontal guide plate 21, the turbulence effect of the trapezoidal plate 4 on the cutting fluid can be adjusted according to the flow rate of the cutting fluid.

[0054] In a specific embodiment, the trapezoidal plate 4 is provided with uniformly arranged filtrate holes 43, which are funnel-shaped; the filtrate holes 43 all penetrate the trapezoidal plate 4; and filter bags 44 are installed inside the filtrate holes 43.

[0055] When the cutting fluid flows onto the trapezoidal plate 4, due to the angle between the trapezoidal plate 4 and the horizontal guide plate 21 during operation, the fluid level gradually rises along the left side surface of the trapezoidal plate 4 under the action of the trapezoidal plate 4 and the rubber flow-blocking component 47. When the fluid level gradually rises to the bottom height of the filter hole 43, the cutting fluid enters the filter hole 43. Since the filter hole 43 penetrates the trapezoidal plate 4 and is equipped with filter bags 44, the cutting fluid flows out from the bottom of the filter hole 43. During this process, the fine debris contained in the cutting fluid is blocked and retained by the filter bags 44, thereby achieving the separation and filtration of this part of the debris. Since the filter hole 43 is funnel-shaped, the inflow of cutting fluid is greater than the outflow, so the fluid level on the trapezoidal plate 4 gradually rises and enters the filter hole 43 on the trapezoidal plate 4 from bottom to top. Inside, when the liquid level is higher than the right end of the trapezoidal plate 4, some cutting fluid will flow over the upper right end of the trapezoidal plate 4. After the cutting fluid flows out from the bottom of the filter hole 43 and the top of the trapezoidal plate 4, it will continue to flow along the upper surface of the horizontal guide plate 21 and then flow onto the inclined guide plate 22, thus circulating. During this process, since the trapezoidal plate 4 and the horizontal guide plate 21 are at a certain angle, the filter hole 43 and the horizontal guide plate 21 will also be at a certain angle. When the cutting fluid flows into the filter hole 43, since the top of the filter hole 43 faces the cutting fluid, some cutting fluid will directly enter the filter hole 43, thereby allowing some debris in the cutting fluid to directly enter the filter hole 43. Under the action of the cutting fluid flow, the filter bag 44's ability to filter debris is enhanced, thereby improving the filtration efficiency of debris in the cutting fluid.

[0056] In a specific embodiment, a second cylinder 141 is fixedly installed at one end of the D plate 14 opposite to the B plate 12; the output end of the second cylinder 141 is fixedly connected to a baffle 24 on one side near the D plate 14.

[0057] When cleaning is required for the horizontal guide plate 21, the inclined guide plate 22, the first sleeve 31, the second sleeve 35, and the interception hook 5, the operator activates the evenly distributed second cylinder 141. Since the output end of the second cylinder 141 is fixedly connected to the baffle 24 on the guide device 2 near the D plate 14, the baffle 24 is fixedly connected to the guide device 2, the guide device 2 is fixedly connected to the rectangular mounting bracket 17, and the rectangular mounting bracket 17 is fixedly connected to the second mounting bracket 16. Furthermore, since the first mounting bracket 15 is fixedly installed on the D plate 14 at the end opposite to the B plate 12, and the second mounting bracket 16 is fixedly installed on the B plate 12 at the end opposite to the D plate 14... The first mounting bracket 15 slides within the second mounting bracket 16, and the B plate 12 can slide along the cavity formed by the second mounting bracket 16, the A plate 11, the C plate 13, the top plate, and the bottom plate. At this time, the output end of the second cylinder 141 extends, pushing the baffle 24, the guide device 2, the rectangular mounting bracket 17, the second mounting bracket 16, and the B plate 12 to move away from the D plate 14. When the output end of the second cylinder 141 extends to its limit, the baffle 24, the guide device 2, the rectangular mounting bracket 17, the second mounting bracket 16, and the B plate 12 are completely pushed out of the housing 1. At this time, the telescopic rotation air... As the output end of cylinder 121 gradually contracts, the second sleeve 35, penetrating the baffle 24 near the B plate 12 and installed within the semi-circular groove 26, gradually slides away from the D plate 14 within the semi-circular groove 26 under the influence of the output end of the telescopic rotary cylinder 121. When the output end of the telescopic rotary cylinder 121 contracts to its limit, the second sleeve 35 is completely withdrawn from the semi-circular groove 26, and the output end of the telescopic rotary cylinder 121 begins to rotate, causing the second sleeve 35 to rotate. At this point, under the influence of gravity, the debris inside the second sleeve 35 will be poured out from the second liquid inlet 36. To clean the debris inside the second sleeve 35, workers can use a brush or air gun to clean and maintain the guide device 2, the first sleeve 31, the trapezoidal plate 4, and each intercepting hook 5. After cleaning, the output end of the telescopic rotary cylinder 121 gradually returns to its initial state, and the second sleeve 35 gradually re-inserts into the first sleeve 31 along the semi-circular groove 26 past the baffle 24. Then, the output end of the second cylinder 141 gradually retracts, causing the baffle 24, the guide device 2, the rectangular mounting bracket 17, the second mounting bracket 16, and the B plate 12 to move in the direction close to the D plate 14 and gradually return to their initial state.

[0058] In a specific embodiment, a collection box 6 is provided below the two first mounting brackets 15 and the second mounting bracket 16 at the bottom of the box body 1; two handles 61 are symmetrically installed on the side of the collection box 6 near the B plate 12; and a pull-out groove 62 corresponding to the collection box 6 is provided on the B plate 12.

[0059] When the staff cleans the inside of the device, the collection box 6 can move away from or towards the D plate 14 along with the B plate 12. The collection box 6 is located below the second mounting bracket 16 and at the bottom of the box body 1. Therefore, the debris will fall into the collection box 6 for temporary storage. When there is a lot of debris in the collection box 6, the collection box 6 can be pulled out from the B plate 12 by the handle 61, so as to facilitate the further processing of the debris.

[0060] In a specific embodiment, the first sleeve 31 passes through the baffle 24 on the side near the D plate 14; both sides of the first sleeve 31 are provided with mounting grooves 25 on the inclined guide plate 22; both sides of the first sleeve 31 are fixedly connected with sliding plates 34, and the sliding plates 34 slide in the mounting grooves 25.

[0061] When further cleaning, maintenance, or replacement of the first sleeve 31 is required, the operator activates the second cylinder 141 to push out the baffle 24, the guide device 2, the rectangular mounting bracket 17, the second mounting bracket 16, and the B plate 12. The operator then removes the trapping hook 5 from the first sleeve 31 and pulls the first sleeve 31 away from the B plate 12. Since the sliding plate 34 is fixedly connected to the first sleeve 31 and slides within the mounting groove 25, the sliding plate 34 gradually slides out of the mounting groove 25. The first sleeve 31 also gradually moves away from the inclined guide plate 22, moving away from the B plate 12. At this point, the operation... Personnel can then use a brush or air gun to further clean and maintain the first sleeve 31, or replace the first sleeve 31. After cleaning and maintaining the first sleeve 31, the slide plate 34 is reinserted into the mounting slot 25 and pushed along the mounting slot 25 towards the B plate 12. The first sleeve 31 is then reinstalled onto the inclined guide plate 22 along with the slide plate 34. After the personnel install the interception hook 5, they start the second cylinder 141. The output end of the second cylinder 141 retracts, restoring the baffle 24, the guide device 2, the rectangular mounting bracket 17, the second mounting bracket 16, and the B plate 12 to their initial state.

[0062] In a specific embodiment, sealing strips are affixed to the parts of plate B 12 that contact plate A 11, plate C 13, top plate, and bottom plate; sealing rings are fitted on the surface of the first sleeve 31 that penetrates the baffle 24 and contacts the baffle 24; sealing rings are fitted on the surface of the second sleeve 35 that penetrates the baffle 24 and contacts the baffle 24; sealing strips are affixed to the parts of the horizontal guide plate 21 and baffle 24 near the liquid inlet 111 that contact plate A 11; sealing strips are provided on the parts of the horizontal guide plate 21 and baffle 24 near the liquid outlet 131 that contact plate C 13; and sealing rings are installed in the bottom hole 27.

[0063] Sealing strips are affixed to the parts of B plate 12 that contact A plate 11, C plate 13, top plate, and bottom plate to ensure the integrity of the device. When the device needs to be cleaned, the second cylinder 141 pushes the entire flow guiding device 2 and B plate 12 away from D plate 14. The sealing strips can effectively ensure the sealing while not affecting the sliding of B plate 12 along the cavity formed by A plate 11, C plate 13, bottom plate, and top plate.

[0064] A sealing ring is fitted on the part of the first sleeve 31 that contacts the baffle 24, allowing the first sleeve 31 to be inserted into the baffle 24 near the D plate 14 side and installed on the inclined guide plate 22 to achieve a seal and prevent cutting fluid leakage. A sealing ring is also fitted on the part of the second sleeve 35 that contacts the baffle 24, allowing the second sleeve 35 to be inserted into the semi-circular groove 26 near the baffle 24 near the B plate 12 side to achieve a seal and prevent cutting fluid leakage. The parts of the horizontal guide plate 21 and baffle 24 near the inlet 111 that contact the A plate 11 are all... Sealing strips are applied to ensure that the cutting fluid does not leak from the contact points while not affecting the sliding of the horizontal guide plate 21 and baffle 24 along the inner side of plate A 11. Sealing strips are also applied to the contact points between the horizontal guide plate 21 and baffle 24 near the outlet 131 and plate C 13 to ensure that the cutting fluid does not leak from the contact points while not affecting the sliding of the horizontal guide plate 21 and baffle 24 along the inner side of plate C 13. The sealing ring installed in the bottom hole 27 can maintain the seal when the output end of the first cylinder 45 extends or retracts, preventing the cutting fluid from leaking.

[0066] An observation window 122 is provided to facilitate staff to observe the interior, enabling timely detection of malfunctions and facilitating maintenance.
