Description

Technical Field

[0001] The present invention relates to the technical field of waste recycling, and particularly to a device for recycling and processing cutting waste of linear guides. Background Art

[0002] A linear guide is a long strip-shaped component unit that supports and guides linear motion. A trajectory groove adapted to slide with a slider unit is usually provided in the length direction of the strip body. During the machining process, the trajectory groove of the linear guide needs to be finely machined through corresponding cutting processes; During the cutting process, cutting wastes of different sizes are generated. After being washed away from the machining position by the coolant in the machine tool, the larger cutting wastes are generally separated from the coolant through natural sedimentation, while some relatively fine cutting wastes are easily carried into the equipment in the coolant circulation system along with the flow of the machine tool coolant, such as passing through a suction pump, a valve passage, etc., thereby accelerating the wear of the equipment in the coolant circulation system. Therefore, it is necessary to recycle and process the cutting wastes of the linear guide in a timely manner; The existing recycling methods mainly intercept and aggregate fine wastes by setting corresponding filtering media, but the filtering media need to be cleaned or replaced in a timely manner. Commonly, an execution component for replacing the filtering media combined with a blocking reminder system for the filtering media is set, such as the Chinese patent publication number "CN210409709U", and the name of this patent is "A paper tape type filter", which mainly prevents filter blockage by setting a transmission chain that can drive the paper tape filter at the filtering position; However, the existing solutions have deficiencies. Since the internal environment of the machine tool is humid under the spraying use of the coolant, the filtering and cleaning component relying on the drive control of a variety of electrical circuit devices has a complex structure and relatively strict installation environment requirements. Therefore, we propose a new solution concept to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a device for recycling and processing cutting wastes of linear guides to solve the deficiencies in the above-mentioned existing technologies.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A device for recycling and processing cutting wastes of linear guides includes a machine tool water tank. A turnover box for receiving coolant containing cutting wastes is provided above the machine tool water tank. A direct discharge channel and a siphon channel communicating with the outside are provided on the turnover box body. Filter meshes are installed at the inlet ends of the direct discharge channel and the siphon channel respectively. A floating scraping shovel that is in sliding contact with each filter mesh is arranged in the turnover box, and the floating scraping shovel can scrape the blocking substances on the filter meshes as the liquid level height changes.

[0005] Preferably, the direct discharge channel includes a columnar pipe whose bottom end is fixedly penetrated through the inner bottom end of the turnover box, and a long strip opening that constitutes the inlet end of the direct discharge channel is formed on the side surface of the bottom end of the columnar pipe.

[0006] Preferably, the siphon channel includes a siphon pipe located inside the columnar pipe. The inlet end of the siphon pipe penetrates through the columnar pipe and is close to the position above the inner bottom of the turnover box, and the bottom end of the siphon pipe is communicated with the machine tool water tank.

[0007] Preferably, the floating scraping shovel includes a cavity ring plate movably sleeved on the columnar pipe, and a scraping shovel capable of scraping the filter screen is installed on the inner ring surface of the cavity ring plate.

[0008] Preferably, a piston pipe extending into the machine tool water tank is provided at the bottom end of the columnar pipe. A piston block is slidably fitted inside the piston pipe. A guide pipe is fixedly penetrated through the piston block. A spray head facing the long strip opening is fixed at the top end of the guide pipe. One-way valves with the same valve direction are respectively fixed at the bottom end of the guide pipe and the bottom end of the piston pipe.

[0009] Preferably, the guide pipe is connected to the cavity ring plate through a U-shaped connecting rod.

[0010] Preferably, the siphon pipe is connected to the turnover box through a plurality of connecting rods, and the siphon pipe and the piston pipe are fixedly arranged in parallel.

[0011] Preferably, the length direction line of the long strip opening is parallel to the axis line of the columnar pipe. A portal frame fixed to the filter screen is slidably installed in the length direction of the long strip opening, and the portal frame can drive the filter screen to move in the long strip opening.

[0012] Preferably, a toothed roller rotatably installed with the turnover box is provided above the columnar pipe. The toothed roller is connected to the top end of the portal frame through an engaged toothed rod, and a rack fixed to the U-shaped connecting rod is engaged with the toothed roller.

[0013] Preferably, a collection box located directly below the columnar pipe is fixed to the top of the machine tool water tank.

[0014] In the above technical solution, a device for recycling and treating cutting waste of linear guide rails provided by the present invention is provided. By setting a direct drainage channel and a siphon channel on the turnover box, the coolant in the turnover box can flow into the machine tool water tank under the action of gravity. And installation filters are arranged at the inlet ends of the direct drainage channel and the siphon channel to intercept fine cutting waste in the coolant. When the filter of the direct drainage channel is blocked by a blocking object, the liquid level in the turnover box rises until the coolant in the turnover box is discharged through the siphon channel. As a result, the floating scraper descends in the turnover box, and the floating scraper can scrape the blocking object on the filter, making the filter of the direct drainage channel unblocked. During this process, no electrical circuit equipment is used for driving, and the structure is simple. The whole action responds in a timely manner, can be used in a reciprocating cycle, realizes automatic treatment, is green and energy-saving, and also reduces the requirements for the installation environment.

[0018] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0019] The circulating flow path of the coolant on the machine tool is roughly as follows. During the machining of the linear guide through the machine tool, the coolant will be flushed towards the machining position. As a result, the cutting waste of the linear guide will flow towards the lower part of the machine tool together with the coolant. The transfer box 2 can hold and receive the coolant that converges and accumulates from the machining position of the machine tool. Then, the coolant in the transfer box 2 will flow into the machine tool water tank 1. Since the coolant in the machine tool is recycled, the coolant in the machine tool water tank is re-flushed towards the machining position through the corresponding pump body.

[0020] Please refer to Figure 1-7 , a device for recycling and treating cutting waste of a linear guide provided by an embodiment of the present invention includes a machine tool water tank 1. A transfer box 2 for receiving coolant containing cutting waste is provided above the machine tool water tank 1. The transfer box 2 is provided with a direct discharge channel 3 and a siphon channel 4 communicating with the outside. Filter screens 5 are installed at the inlet ends of the direct discharge channel 3 and the siphon channel 4. A floating scraping shovel 6 that is in sliding contact with each filter screen 5 is provided in the transfer box 2. The floating scraping shovel 6 can scrape the blocking substances on the filter screen 5 as the liquid level height changes; Specifically, the orientations of the inlet ends of the direct discharge channel 3 and the siphon channel 4 are parallel to the vertical plane, and the mesh body of the filter screen 5 can be flush and adapted to the inlet end of the direct discharge channel 3 and the inlet end of the siphon channel 4; The working principle in actual use is that the transfer box 2 flows the coolant containing cutting waste into the machine tool water tank 1 through the direct discharge channel 3. Since a filter screen 5 is installed at the inlet end of the direct discharge channel 3, the filter screen 5 in the unblocked state isolates and intercepts the cutting waste in the transfer box 2. As the cutting waste accumulates, when the filter screen 5 at the inlet end of the direct discharge channel 3 is completely blocked by the cutting waste, the direct discharge channel 3 is in a blocked state where liquid cannot be discharged. However, the transfer box 2 still continues to receive the coolant containing cutting waste, resulting in an increase in the liquid level in the transfer box 2; When the liquid level height in the turnover box 2 exceeds the highest position of the siphon channel 4, at this time, the siphon channel 4 quickly guides all the coolant in the turnover box 2 into the machine tool water tank 1, and the liquid level height in the turnover box 2 drops rapidly. And during this process, the coolant can also be filtered by the filter screen 5 at the inlet end of the siphon channel 4; During the rapid drop of the liquid level height in the turnover box 2, the floating scraping shovel 6 can scrape the blockage on the filter screen 5 at the inlet end of the direct discharge channel 3 as the liquid level drops, so that the filter screen 5 returns to a smooth state, so that the turnover box 2 can flow the coolant containing cutting waste through the direct discharge channel 3 into the machine tool water tank 1 again, and the normal use of the direct discharge channel 3 is restored; It should be further noted that during the descending process of the floating scraping shovel 6, it can also scrape the blockage on the filter screen 5 at the inlet end of the siphon channel 4. During this process, it is not driven by any electrical circuit equipment, and the structure is simple. The whole action responds in a timely manner, can be used in a reciprocating cycle, realizes automatic processing, is green and energy-saving, and also reduces the requirements for the installation environment. In another embodiment provided by the present invention, the direct discharge channel 3 includes a column tube 31 whose bottom end is fixedly penetrated through the inner bottom end of the turnover box 2. A long strip opening 32 constituting the inlet end of the direct discharge channel 3 is opened on the side surface of the bottom end of the column tube 31. Among them, the axis line of the column tube 31 is perpendicular to the horizontal plane. The filter screen 5 is preferably a rigid mesh body, and the filter screen 5 is installed in the long strip opening 32 to intercept the cutting waste in the coolant passing through the filter screen 5.

[0021] In another embodiment provided by the present invention, the siphon channel 4 includes a siphon tube 41 located in the column tube 31. The inlet end of the siphon tube 41 penetrates through the column tube 31 and is close to the position above the inner bottom of the turnover box 2, so that during the siphon process, it is convenient to maximize the suction of the cooling water in the turnover box 2. Among them, the inlet end of the siphon tube 41 is perpendicular to the vertical plane, the inlet end of the siphon tube 41 is flush with the side surface of the through column tube 31, the filter screen 5 is flush with the inlet end of the siphon tube 41, the filter screen 5 at the inlet end of the siphon tube 41 is located on the moving path of the floating scraping shovel 6, the filter screen 5 at the inlet end of the siphon tube 41 can be scraped by the floating scraping shovel 6, the bottom end of the siphon tube 41 is communicated with the machine tool water tank 1, so as to introduce the suctioned cooling water into the machine tool water tank 1, and the machine tool water tank 1 is communicated with the outside atmosphere.

[0022] In another embodiment provided by the present invention, the floating scraping shovel 6 includes a cavity ring plate 61 movably sleeved on the column tube 31. The outermost contour line of the cavity ring plate 61 is a rectangular structure adapted to the inner contour line of the turnover box 2, so as to limit the horizontal axial rotation of the cavity ring plate 61 when floating. A scraping shovel 62 capable of scraping the filter screen 5 is installed on the inner ring surface of the cavity ring plate 61. Preferably, the cutting edge surface of the scraping shovel 62 is adapted to contact the contact surface of the filter screen 5; In actual use, the cavity ring disk 61 drives the scraper 62 to move along the axial direction of the column tube 31 according to the change of the liquid level height in the turnover box 2. For example, when the liquid level in the turnover box 2 rises, the cavity ring disk 61 drives the scraper 62 to move upward, so that the scraper 62 scrapes the filter screen 5 from bottom to top. Conversely, when the liquid level in the turnover box 2 drops, the cavity ring disk 61 drives the scraper 62 to move downward, so that the scraper 62 scrapes the filter screen 5 from top to bottom, thereby allowing the attachments on the filter screen 5 to be detached, keeping the filter screen 5 in an unobstructed state.

[0023] In another embodiment provided by the present invention, a piston tube 7 extending into the machine tool water tank 1 is provided at the bottom end of the column tube 31, and the number of piston tubes 7 can be selected to be multiple, the axis line of the piston tube 7 is parallel to the axis line of the column tube 31, and a piston block 8 is slidably adapted in the piston tube 7, and a guide tube 9 is fixedly passed through the piston block 8, and the axis line of the guide tube 9 is parallel to the axis line of the piston tube 7, and a nozzle 10 facing the long strip opening 32 is fixed at the top of the guide tube 9, and a one-way valve 11 with the same valve direction is fixed at the bottom end of the guide tube 9 and the bottom end of the piston tube 7, so that a piston space is formed between the bottom end of the guide tube 9 and the bottom end of the piston tube 7, and the two one-way valves 11 allow the flow direction of the liquid to be directed upward, that is, the one-way valve 11 in the piston tube 7 only allows the fluid to enter the piston tube 7, and the one-way valve 11 in the guide tube 9 only allows the fluid to enter the guide tube 9; Furthermore, the guide tube 9 is connected to the cavity ring disk 61 via a U-shaped connecting rod 12, and the opening of the U-shaped opening of the U-shaped connecting rod 12 is downward, so that the guide tube 9 can move synchronously with the cavity ring disk 61 in the vertical direction; Its working principle in actual use is that when the cavity ring disc 61 rises with the inner liquid level of the turnover box 2, the cavity ring disc 61 drives the guide tube 9 to pull up vertically upward through the U-shaped connecting rod 12, so that the piston block 8 moves upward in the piston tube 7 along with the guide tube 9. Since the one-way valve 11 in the piston tube 7 only allows the fluid to enter the piston tube 7, the one-way valve 11 in the guide tube 9 only allows the fluid to enter the guide tube 9. At this time, the piston space becomes larger and the pressure in the space decreases. At this time, the piston space is in a negative pressure state, so that the coolant in the machine tool water tank 1 can be drawn into the piston space through the piston tube 7 immersed in the machine tool water tank 1; When the cavity ring disk 61 descends along with the inner liquid level of the turnover box 2, the cavity ring disk 61 drives the guide tube 9 to perform a vertical downward pressure movement through the U-shaped connecting rod 12, so that the piston block 8 moves downward in the piston tube 7 along with the guide tube 9. At this time, the piston space becomes smaller due to compression and the pressure increases, and the piston space is in a high-pressure state, so that the coolant in the piston space flows along the guide tube 9 and rushes to the filter screen 5 through the nozzle 10, so that the blockage attached to the outside of the filter screen 5 is impacted by the water flow inside the filter screen 5, which helps to improve the cleaning effect of separating the attachments on the filter screen 5 from the filter screen 5.

[0024] In another embodiment provided by the present invention, the siphon tube 41 is connected to the turnover box 2 by a plurality of connecting rods 42, the siphon tube 41 and the piston tube 7 are fixed in parallel, and the siphon tube 41 and the piston tube 7 can be fixed by welding or by tying with a hoop, so that the position of the piston tube 7 on the turnover box 2 can be restricted and determined.

[0025] In another embodiment provided by the present invention, the length direction line of the long strip opening 32 is parallel to the axis line of the column tube 31, and a door-shaped frame 33 fixed to the filter screen 5 is slidably installed in the length direction of the long strip opening 32, and the door-shaped frame 33 can drive the filter screen 5 to move in the long strip opening 32; Furthermore, a toothed roller wheel 17 is provided above the column tube 31 and is rotatably mounted with the turnover box 2. The axis of the toothed roller wheel 17 is parallel to the horizontal plane. The toothed roller wheel 17 is located above the door-shaped frame 33. The toothed roller wheel 17 is connected to the top of the door-shaped frame 33 through the meshing toothed rod 14. The toothed roller wheel 17 is meshed with a rack 13 fixed to the U-shaped connecting rod 12. The length direction line of the rack 13 is parallel to the length direction line of the straight portion of the U-shaped connecting rod 12. A collection box 15 is fixed on the top of the machine tool water tank 1 and is located directly below the column tube 31. A drainage plate 16 is provided in the column tube 31 and is fixed to the side surface of the bottom end of the door-shaped frame 33. It should be particularly noted that the inlet end of the siphon tube 41 passes through the column tube 31 and is close to the upper position of the inner bottom of the turnover box 2. There are two inlet ends of the siphon tube 41, which are arranged from far to near in order of the distance from the bottom of the turnover box 2 as a first inlet end 411 and a second inlet end 412. The first inlet end 411 and the second inlet end 412 are both provided with a filter screen 5, and the first inlet end 411 and the second inlet end 412 are each provided with a blocking cover; Furthermore, a filter ring 63 is fixed at the bottom of the cavity ring disk 61. The filter ring 63 is formed by connecting the end of a belt filter. The ring body of the filter ring 63 is located outside the column tube 31. The center of the filter ring 63 coincides with the axial center line of the column tube 31. The filter ring 63 is a hard ring body. The outside of the filter ring 63 is adapted to be equipped with a scraper ring 64, which is fixed to the side wall of the turnover box 2.

[0026] During actual use, the working principle is as follows. In the normal state, the first inlet end 411 located at the upper position is kept open, and the second inlet end 412 located at the lower position is in a blocked state by the covering of the blocking cover. In this state, the siphon tube 41 is in a constant suction state. The filter screen 5 is movably installed in the long strip opening 32 through the portal frame 33. The filter screen 5 and the portal frame 33 intercept the cutting waste in the coolant passing through the long strip opening 32. The rack 13 and the gear roller 17 are in a separated state. The coolant flowing out of the long strip opening 32 is diverted to the piston tube 7 through the diversion plate 16 and then flows along the piston tube 7 into the machine tool water tank 1, thereby preventing the coolant from splashing. When it is necessary to discharge the cutting waste of the lock scraping shovel in the turnover box 2, at this time, the second inlet end 412 is opened, and the first inlet end 411 is in a blocked state by the covering of the blocking cover, so as to increase the siphon depth of the coolant in the turnover box 2 by the siphon tube 41. In this state, the siphon tube 41 is in a deep suction state. When the siphon tube 41 is in the deep suction state, during the downward movement of the U-shaped connecting rod 12 along with the cavity ring plate 61, at this time, the rack 13 also moves downward towards the position of the gear roller 17. When the rack 13 meshes with the gear roller 17, at this time, the bottom of the cavity ring plate 61 also approaches the inner bottom of the turnover box 2. At this time, the cavity ring plate 61 receives the upward buoyancy of the coolant in the turnover box 2 and the upward meshing resistance between the rack 13 and the gear roller 17, so as to offset the gravity of the cavity ring plate 61. When the coolant in the turnover box 2 is completely siphoned by the siphon tube 41, at this time, the buoyancy received by the cavity ring plate 61 is in the weakest state, and the gravity of the cavity ring plate 61 is greater than the upward meshing resistance between the rack 13 and the gear roller 17. At this time, the rack 13 drives the gear roller 17 to rotate axially, so that the rack bar 14 is meshed by the gear roller 17 to generate an upward pulling force on the portal frame 33, and then the portal frame 33 moves upward along the length direction of the long strip opening 32, so that a gap is formed between the bottom end of the portal frame 33 and the bottom end of the long strip opening 32.

[0027] At the same time, the cavity ring plate 61 descends to the lowest position. At this time, the cavity ring plate 61 contacts the inner bottom of the turnover box 2 through the filter ring 63. The space between the bottom of the cavity ring plate 61 and the turnover box 2 is divided into two parts, namely the inner space of the ring and the outer space of the ring, by the filter ring 63. And the coolant on the machine tool still continuously flows into the turnover box 2. When the coolant enters the inner space of the ring from the outer space of the ring, the coolant needs to flow towards the gap through the filter ring 63. The filter ring 63 plays a filtering role at this time. The coolant after being filtered by the filter ring 63 then flows towards the gap. The coolant can discharge the cutting waste scraped from the filter screen 5 by the scraping shovel 62 through the gap from the turnover box 2, and then fall into the collection box 15 directly below. The falling trajectory of the cutting waste through the gap is not on the same vertical line as the falling trajectory of the coolant into the machine tool water tank 1. When the filter ring 63 becomes blocked, the water level in the turnover box 2 rises at this time. The buoyancy of the coolant in the space outside the turnover box 2 acting on the cavity ring plate 61 increases, so that the cavity ring plate 61 rises and floats again. The filter ring 63 also moves upward and separates from the bottom of the turnover box 2, so that the space inside the ring and the space outside the ring are restored to one body. During this process, the scraping ring 64 also scrapes off the blockage attached to the filter ring 63; Meanwhile, under the meshing drive of the gear roller 17, the rack 14 and the rack 13, the gantry frame 33 moves downward so that the notch is closed again. At this time, the coolant in the turnover box 2 needs to be filtered through the filter screen 5 again.

[0028] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
