Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, specifically to a linear guide rail cutting waste recycling and processing device. Background Technology

[0002] A linear guide is a long strip-shaped component unit that supports and guides linear motion. It usually has a track groove along its length that is adapted to slide with a slider unit. During the manufacturing process, the track groove of the linear guide needs to be precision machined through corresponding cutting processes. During the cutting process, cutting waste of different sizes is generated. After being flushed away from the machining position by the coolant in the machine tool, larger cutting waste is generally separated from the coolant by natural sedimentation. However, some smaller cutting waste is more likely to enter the equipment in the coolant circulation system with the flow of machine tool coolant, such as through suction pumps and valve channels, thereby accelerating the wear of the equipment in the coolant circulation system. Therefore, it is necessary to recycle and process the cutting waste of linear guides in a timely manner. Existing recycling methods mainly involve setting up corresponding filter media to intercept and collect fine waste. However, it is necessary to clean or replace the filter media in a timely manner. A common approach is to set up a filter media replacement execution component that is combined with a filter media blockage reminder system. For example, Chinese patent publication number "CN210409709U" is titled "A Paper Tape Filter". It mainly prevents filter blockage by setting a transmission mesh chain at the filter position that can drive the paper tape filter. However, the existing solution has shortcomings. Due to the use of coolant spray, the internal environment of the machine tool is humid, which makes the filter cleaning component, which relies on the drive control of multiple electrical circuit devices, complex in structure and has relatively harsh installation requirements. Therefore, we propose a new solution to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a linear guide rail cutting waste recycling and processing device to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A linear guide cutting waste recycling and processing device includes a machine tool water tank. Above the machine tool water tank is a turnover box for holding coolant containing cutting waste. The turnover box has a straight discharge channel and a siphon channel communicating with the outside. Each inlet end of the straight discharge channel and the siphon channel is equipped with a filter screen. The turnover box is equipped with a floating scraper that slides in contact with each filter screen. The floating scraper can scrape the blockage on the filter screen as the liquid level changes.

[0005] Preferably, the straight discharge channel includes a column tube whose bottom end is fixedly inserted through the bottom end of the turnover box, and the bottom end of the column tube has an elongated opening on its side that forms the entrance end of the straight discharge channel.

[0006] Preferably, the siphon channel includes a siphon pipe located inside the column tube, the inlet end of the siphon pipe penetrating the column tube and located near the inner bottom of the turnover box, and the bottom end of the siphon pipe being connected to the machine tool water tank.

[0007] Preferably, the floating scraper includes a hollow ring disc movably sleeved on the column tube, and a scraper capable of cleaning the filter screen is installed on the inner ring surface of the hollow ring disc.

[0008] Preferably, the bottom end of the column tube is provided with a piston tube that extends into the machine tool water tank. A piston block is slidably fitted inside the piston tube. A guide tube is fixedly inserted through the piston block. A nozzle facing the elongated opening is fixed at the top end of the guide tube. A one-way valve with the same valve direction is fixed at the bottom end of the guide tube and the bottom end of the piston tube.

[0009] Preferably, the guide tube is connected to the cavity annular disk by a U-shaped connecting rod.

[0010] Preferably, the siphon tube is connected to the turnover box by multiple connecting rods, and the siphon tube and the piston tube are fixed in parallel.

[0011] Preferably, the length direction line of the elongated opening is parallel to the axis of the column tube, and a gate-shaped frame fixed to the filter screen is slidably installed along the length direction of the elongated opening. The gate-shaped frame can drive the filter screen to move within the elongated opening.

[0012] Preferably, a toothed roller is provided above the column tube and is rotatably mounted with the turnover box. The toothed roller is connected to the top of the gate frame through a meshing toothed rod, and a rack that is fixed to the U-shaped connecting rod is meshed on the toothed roller.

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

[0014] In the above technical solution, the present invention provides a linear guide cutting waste recycling and processing device. By setting a straight discharge channel and a siphon channel on the turnover box, the coolant in the turnover box can flow to the machine tool water tank under the action of gravity. Filter screens are installed at the inlet ends of the straight discharge channel and the siphon channel to intercept small cutting waste in the coolant. When the filter screen in the straight discharge channel is blocked by blockage, the liquid level in the turnover box rises until the coolant in the turnover box is discharged through the siphon channel. At this time, the floating scraper moves downward in the turnover box and can scrape the blockage on the filter screen, so that the filter screen in the straight discharge channel is unobstructed. In this process, no electrical circuit equipment is used for driving. Moreover, the structure is simple, the whole action is timely, it can be used repeatedly, realizes automated processing, is green and energy-saving, and also reduces the requirements for the installation environment.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] The coolant circulation path on the machine tool is roughly as follows: during the machining of the straight guideway, the coolant is flushed towards the machining position, and the cutting waste of the straight guideway flows down the machine tool along with the coolant. The turnover box 2 can hold and receive the coolant that flows from the machining position of the machine tool, and then the coolant in the turnover box 2 flows 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 flushed back to the machining position by the corresponding pump.

[0020] Please see Figure 1-7 The present invention provides a linear guide cutting waste recycling and processing device, including a machine tool water tank 1, a turnover box 2 for holding coolant containing cutting waste is provided above the machine tool water tank 1, the turnover box 2 is provided with a straight discharge channel 3 and a siphon channel 4 communicating with the outside, and a filter screen 5 is installed at each inlet end of the straight discharge channel 3 and the siphon channel 4. A floating scraper 6 is provided inside the turnover box 2 and slides in contact with each filter screen 5. The floating scraper 6 can scrape the blockage on the filter screen 5 as the liquid level changes. Specifically, the orientation of each inlet end of the straight channel 3 and the siphon channel 4 is parallel to the vertical plane, and the mesh of the filter screen 5 can be flush with and adapted to the inlet end of the straight channel 3 and the inlet end of the siphon channel 4. In actual use, the working principle is as follows: the turnover box 2 carries the coolant containing cutting waste through the straight discharge channel 3 into the machine tool water tank 1. The inlet end of the straight discharge channel 3 is equipped with a filter screen 5. Therefore, when the filter screen 5 is unobstructed, it isolates and traps the cutting waste in the turnover box 2. As the cutting waste accumulates, when the filter screen 5 at the inlet end of the straight discharge channel 3 is completely blocked by the cutting waste, the straight discharge channel 3 is in a blocked state where it cannot drain the liquid. However, the turnover box 2 continues to collect the coolant containing cutting waste, which causes the liquid level in the turnover box 2 to rise. When the liquid level in the turnover box 2 exceeds the highest position of the siphon channel 4, the siphon channel 4 will quickly guide all the coolant in the turnover box 2 into the machine tool water tank 1, and the liquid level in the turnover box 2 will drop rapidly. During this process, the coolant can also be filtered through the filter screen 5 at the inlet end of the siphon channel 4. As the liquid level in the turnover box 2 rapidly decreases, the floating scraper 6 can scrape away the blockages on the filter screen 5 at the inlet end of the straight discharge channel 3 as the liquid level decreases, thereby restoring the filter screen 5 to its unobstructed state. This allows the turnover box 2 to allow the coolant containing cutting waste to flow back into the machine tool water tank 1 through the straight discharge channel 3, restoring the normal use of the straight discharge channel 3. It should be further explained that during the descent of the floating scraper 6, it can also scrape away the blockages on the filter screen 5 at the inlet end of the siphon channel 4. In this process, no electrical circuit equipment is required for driving, and the structure is simple. The whole action is timely and can be used repeatedly to achieve automated processing, green energy saving, and also reduce the requirements of the installation environment. In another embodiment of the present invention, the straight discharge channel 3 includes a column tube 31 whose bottom end is fixedly inserted through the bottom end of the turnover box 2. The bottom end of the column tube 31 has an elongated opening 32 forming the inlet end of the straight discharge channel 3. The axis of the column tube 31 is perpendicular to the horizontal plane. The filter screen 5 is preferably a rigid mesh. The filter screen 5 is installed in the elongated opening 32 to intercept cutting waste in the coolant passing through the filter screen 5.

[0021] In another embodiment of the present invention, the siphon channel 4 includes a siphon pipe 41 located inside the column tube 31. The inlet end of the siphon pipe 41 penetrates the column tube 31 and is located near the inner bottom of the turnover box 2, thereby maximizing the suction of cooling water in the turnover box 2 during the siphon process. The inlet end of the siphon pipe 41 is perpendicular to the vertical plane and flush with the side of the column tube 31. The filter screen 5 is flush with the inlet end of the siphon pipe 41 and is located on the moving path of the floating scraper 6. The filter screen 5 at the inlet end of the siphon pipe 41 can be scraped by the floating scraper 6. The bottom end of the siphon pipe 41 is connected to the machine tool water tank 1, thereby guiding the suctioned cooling water into the machine tool water tank 1, and the machine tool water tank 1 is connected to the outside atmosphere.

[0022] In another embodiment of the present invention, the floating scraper 6 includes a hollow ring disk 61 movably sleeved on the column tube 31. The outermost contour of the hollow ring disk 61 is a rectangular structure that matches the inner contour of the turnover box 2, thereby restricting the horizontal axial rotation of the hollow ring disk 61 when it floats. A scraper 62 capable of cleaning the filter screen 5 is installed on the inner ring surface of the hollow ring disk 61. Preferably, the scraper blade surface of the scraper 62 is adapted to contact the contact surface of the filter screen 5. In practical use, the cavity ring disc 61 drives the scraper 62 to move along the axis of the column tube 31 according to the change in the liquid level in the turnover box 2. For example, when the liquid level in the turnover box 2 rises, the cavity ring disc 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 falls, the cavity ring disc 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 deposits on the filter screen 5 to be removed and keeping the filter screen 5 in a clear state.

[0023] In another embodiment of the present invention, the bottom end of the column tube 31 is provided with a piston tube 7 extending into the machine tool water tank 1. The number of piston tubes 7 can be selected as multiple. The axis of the piston tube 7 is parallel to the axis of the column tube 31. A piston block 8 is slidably adapted inside the piston tube 7. A guide tube 9 is fixedly passed through the piston block 8. The axis of the guide tube 9 is parallel to the axis of the piston tube 7. A nozzle 10 facing the elongated opening 32 is fixed at the top end of the guide tube 9. 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. The two one-way valves 11 allow the liquid to flow upwards. 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 by a U-shaped connecting rod 12. The opening of the U-shaped opening of the U-shaped connecting rod 12 faces downward, and the U-shaped connecting rod 12 enables the guide tube 9 to move synchronously with the cavity ring disk 61 in the vertical direction. Its working principle in actual use is as follows: when the cavity ring disk 61 rises with the liquid level inside the turnover box 2, the cavity ring disk 61 drives the guide pipe 9 to move vertically upward through the U-shaped connecting rod 12, so that the piston block 8 moves upward with the guide pipe 9 inside the piston tube 7. Since the one-way valve 11 in the piston tube 7 only allows fluid to enter the piston tube 7, and the one-way valve 11 in the guide pipe 9 only allows fluid to enter the guide pipe 9, the piston space becomes larger and the pressure inside 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. As the liquid level inside the turnover box 2 decreases, the cavity ring disk 61 drives the guide pipe 9 to move vertically downward through the U-shaped connecting rod 12. This causes the piston block 8 to move downward inside the piston tube 7 along with the guide pipe 9. At this time, the piston space is compressed and the pressure increases. The piston space is under high pressure, which causes the coolant in the piston space to flow along the guide pipe 9 and through the nozzle 10 onto the filter screen 5. This causes the blockages attached to the outside of the filter screen 5 to be impacted by the water flow inside the filter screen 5, which helps to improve the cleaning effect of separating the blockages from the filter screen 5.

[0024] In another embodiment of the present invention, the siphon tube 41 is connected to the turnover box 2 by a plurality of connecting rods 42, and the siphon tube 41 and the piston tube 7 are fixed in parallel. The siphon tube 41 and the piston tube 7 can be fixed by welding or by binding with a hoop, thereby limiting and determining the position of the piston tube 7 on the turnover box 2.

[0025] In another embodiment of the present invention, the length direction line of the elongated opening 32 is parallel to the axis of the column tube 31, and a gate-shaped frame 33 fixed to the filter screen 5 is slidably installed in the length direction of the elongated opening 32. The gate-shaped frame 33 can drive the filter screen 5 to move within the elongated opening 32. Furthermore, a toothed roller 17 is provided above the column tube 31 and is rotatably mounted to the turnover box 2. The axis of the toothed roller 17 is parallel to the horizontal plane. The toothed roller 17 is located above the portal frame 33. The toothed roller 17 is connected to the top of the portal frame 33 through a meshing toothed rod 14. A rack 13 that is fixed to the U-shaped connecting rod 12 is meshed on the toothed roller 17. The length direction line of the rack 13 is parallel to the length direction line of the straight part of the U-shaped connecting rod 12. The top of the machine tool water tank 1 is fixed with a collection box 15 located directly below the column tube 31, and the column tube 31 is provided with a diversion plate 16 fixed to the bottom side of the door frame 33. It should be noted that the inlet end of the siphon tube 41 passes through the column tube 31 and is located near the bottom of the turnover box 2. The siphon tube 41 has two inlet ends, which are arranged from farthest to near the bottom of the turnover box 2 as the first inlet end 411 and the second inlet end 412. Both the first inlet end 411 and the second inlet end 412 are equipped with filter screens 5, and each of the first inlet end 411 and the second inlet end 412 is equipped with a sealing cap. 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 ends of a strip filter screen. 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 axis of the column tube 31. The filter ring 63 is a rigid ring body. A scraping ring 64 is adapted to be provided on the outside of the filter ring 63. The scraping ring 64 is fixed to the side wall of the turnover box 2.

[0026] In actual use, the working principle is as follows: Under normal conditions, the first inlet end 411, which is located at the top, is kept in the open state, and the second inlet end 412, which is located at the bottom, is kept in the closed state by the sealing cover. Under this state, the siphon tube 41 is in the constant suction state. The filter screen 5 is installed in the long slot 32 through the gate frame 33. The filter screen 5 and the gate frame 33 intercept the cutting waste in the coolant passing through the long slot 32. The rack 13 and the toothed roller 17 are in the separated state. The coolant flowing out of the long slot 32 is guided to the piston tube 7 through the guide plate 16 and then guided to the machine tool water tank 1 along the piston tube 7, thereby preventing coolant splashing. When it is necessary to discharge the cutting waste from the lock scraper in the turnover box 2, the second inlet end 412 is in the open state, and the first inlet end 411 is in the closed state by the cover, thereby increasing the siphon depth of the siphon pipe 41 to the coolant in the turnover box 2. In this state, the siphon pipe 41 is in the deep suction state. When the siphon tube 41 is in the deep suction state, as the U-shaped connecting rod 12 descends with the cavity ring disk 61, the rack 13 also moves downward toward the position of the toothed roller 17. When the rack 13 meshes with the toothed roller 17, the bottom of the cavity ring disk 61 is also close to the inner bottom of the turnover box 2. At this time, the cavity ring disk 61 is subjected to the upward buoyancy of the coolant in the turnover box 2 and the upward meshing resistance between the rack 13 and the toothed roller 17, which cancels out the gravity of the cavity ring disk 61. After the coolant in the turnover box 2 is completely siphoned by the siphon pipe 41, the buoyancy of the cavity ring disk 61 is at its weakest. The weight of the cavity ring disk 61 is greater than the upward meshing resistance between the rack 13 and the toothed roller 17. At this time, the rack 13 drives the toothed roller 17 to rotate axially, so that the rack 14 is subjected to the meshing action of the toothed roller 17 and generates an upward pulling force on the portal frame 33. Then the portal frame 33 moves upward along the length direction of the long opening 32, thus forming a gap between the bottom end of the portal frame 33 and the bottom end of the long opening 32.

[0027] At the same time, the cavity ring disk 61 descends to its lowest position. At this time, the cavity ring disk 61 contacts the bottom of the turnover box 2 through the filter ring 63. The space between the bottom of the cavity ring disk 61 and the turnover box 2 is divided into two parts: the inner space and the outer space by the filter ring 63. Meanwhile, the coolant on the machine tool continues to flow into the turnover box 2. During the process of the coolant moving from the outer space to the inner space, the coolant needs to flow towards the notch 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 flows towards the notch. The coolant can discharge the cutting waste scraped by the scraper 62 from the filter screen 5 through the notch into the turnover box 2 and then fall into the collection box 15 directly below. The trajectory of the cutting waste falling through the notch is not on the same vertical line as the trajectory of the coolant falling into the machine tool water tank 1. When the filter ring 63 becomes clogged, the water level in the turnover box 2 rises, and the coolant in the outer space of the turnover box 2 increases the buoyancy of the cavity ring plate 61, causing the cavity ring plate 61 to rise and float again. The filter ring 63 also moves upward and separates from the bottom of the turnover box 2, so that the inner space and the outer space of the ring are restored to one. During this process, the scraping ring 64 also scrapes off the blockage attached to the filter ring 63. At the same time, under the meshing transmission of the toothed roller 17, the toothed bar 14 and the rack 13, the gate frame 33 moves downward, causing the notch to close again. At this time, the coolant in the turnover box 2 needs to be filtered again through the filter screen 5.

[0028] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
