Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and more specifically to a chip removal and cleaning device for CNC machine tools. Background Technology

[0002] Large CNC machine tools generate a large amount of chips during machining. These chips are transported to the tail of the machine tool by the conveyor devices on both sides of the machine tool. These chips usually carry a large amount of cutting fluid. The accumulated chips can cause the cutting fluid to leak onto the ground or other places, resulting in waste of cutting fluid and pollution of the workshop floor and the surrounding environment. This increases the difficulty of environmental cleaning and cutting fluid recycling. Therefore, it is necessary to regularly clean the chips from CNC machine tools to prevent chip accumulation from affecting the machining efficiency and accuracy of the machine tool.

[0003] Some existing chip removal devices, during the chip removal process from machine tools, often cause the strip-shaped chips to entangle and form "chip balls" at bends or interfaces, leading to blockages. Simultaneously, the cutting fluid carried by the chips splashes everywhere, easily polluting the surrounding floor, creating a slippery and dangerous workspace, and increasing subsequent waste fluid treatment costs. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a chip removal and cleaning device for CNC machine tools, which at least partially solves the problems mentioned in the background art.

[0005] The technical solution adopted in this invention is as follows: A chip removal and cleaning device for CNC machine tools, comprising: The crushing box has a support at the bottom and a cover and feed inlet at the top; A solid-liquid separation unit is located below the crushing box, and its upper end extends through the bottom wall of the crushing box. The feeding chute has one end mounted on a support and positioned near the feed inlet, and the other end connected to the chip removal port of the CNC machine tool. The solid-liquid separation unit includes a base, a fixed cylinder, a rotary motor, a conical block, and a movable cylinder. The fixed cylinder is located on the base, and its upper end extends through the crushing chamber. The rotary motor is located inside the base, the conical block is located at the output shaft end of the rotary motor, and the movable cylinder is fixedly located on the side wall of the conical block.

[0006] Furthermore, the crushing box is equipped with a baffle, which is located at the rear end of the crushing box, and the fixing cylinder is located inside the baffle.

[0007] The fixed cylinder has a guide ring on its upper wall, which is located near the baffle and extends to the top of the movable cylinder wall.

[0008] Furthermore, the outer wall of the movable cylinder is provided with a partition, the partition is inclined, and the edge of the partition is movably fitted to the inner wall of the fixed cylinder.

[0009] Furthermore, the movable cylinder wall is provided with several sets of filter holes, all of which are located above the partition plate.

[0010] Furthermore, the lower wall of the movable cylinder is provided with a liquid outlet, which is located above the partition and is positioned near the lower end of the inclined surface of the partition.

[0011] Furthermore, the lower wall of the movable cylinder is provided with a first discharge port, and a solenoid valve is provided at the discharge port; The lower wall of the fixed cylinder is provided with a second discharge port, and a discharge pipe is fixedly provided at the second discharge port.

[0012] In a further embodiment, the inner wall of the movable cylinder is provided with a spiral guide plate, which is set at a 30° rise angle.

[0013] Furthermore, the crushing box is equipped with a crushing component, which is located near the feed inlet; The crushing assembly includes a drive motor, a drive shaft, a driven shaft, a breaker hammer, and an inner liner. The drive motor is fixedly mounted on the outer wall of the crushing chamber, and the output shaft of the drive motor is movably disposed through the crushing chamber. One end of the drive shaft is fixedly mounted on the output shaft of the drive motor, and the other end of the drive shaft is movably disposed on the inner wall of the crushing chamber via a bearing. The driven shaft is disposed close to the drive shaft, and the driven shaft and the drive shaft are movably connected via a transmission belt. The breaker hammer is detachably mounted on the drive shaft and the driven shaft, and the breaker hammer on the drive shaft and the breaker hammer on the driven shaft are tightly engaged. The inner lining plate is provided in two sets. One set of inner lining plates is provided on the lower wall of the feed inlet, and the other set of inner lining plates is provided on the upper wall of the feed inlet. The surface of the inner lining plate is parallel to the rotating plane of the breaker hammer.

[0014] In a further embodiment, a recycling trough is embedded in the lower wall of the feeding trough, the upper end of the recycling trough is flush with the lower wall of the feeding trough, and the recycling trough is located near the bottom of the chain plate.

[0015] In a further embodiment, the CNC machine tool chip removal and cleaning device further includes a filter unit, which is located near the solid-liquid separation unit and below the feeding trough. The inlet end of the filter unit is connected to the liquid outlet.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: One end of the feeding chute is connected to the chip discharge port of the CNC machine tool, and the other end is located near the feed inlet of the crushing box. This allows for efficient and timely delivery of chips into the crushing box, preventing chip accumulation and disorder. The cover plate and feed inlet design on the top of the crushing box facilitate the input of chips, while the support at the bottom provides stable support. The crushing components crush the "chip balls" that are entangled in the chips, making them finer and creating favorable conditions for subsequent solid-liquid separation, thus improving separation efficiency. The combination of the rotary motor, conical block, and movable cylinder utilizes the centrifugal force generated by rotation to effectively separate solid chips from cutting fluid. The separated chips and cutting fluid enter the recycling stage and further filtration and recycling, respectively, achieving rational utilization of resources, reducing waste, and lowering environmental pollution.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0021] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0022] Existing chip removal devices often encounter problems during chip discharge from machine tools. The strip-shaped chips tend to entangle and form "chip balls," causing blockages. Simultaneously, the cutting fluid carried by the chips splashes everywhere, easily contaminating the surrounding floor and creating a slippery and unsafe environment. This not only increases the cost of subsequent waste fluid treatment but also raises safety concerns.

[0023] After recognizing the above problems, this application proposes and discloses a chip removal and cleaning device for CNC machine tools, which can solve the problem of chips entangled into "chip balls" causing blockage, and can separate and recycle cutting fluid.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this disclosure provides a chip removal and cleaning device for CNC machine tools, comprising: The crushing box 1 has a support 2 at the bottom and a cover plate 3 and a feed inlet 4 at the top; The solid-liquid separation unit 5 is located below the crushing box 1, and its upper end extends through the bottom wall of the crushing box 1. The feeding trough 6 has one end set on the bracket 2 and near the feed port 4, and the other end is connected to the chip discharge port of the CNC machine tool. The solid-liquid separation unit 5 includes a base 7, a fixed cylinder 8, a rotary motor 9, a conical block 10, and a movable cylinder 11. The fixed cylinder 8 is mounted on the base 7 and its upper end extends through the crushing chamber 1. The rotary motor 9 is mounted inside the base 7. The conical block 10 is mounted on the output shaft end of the rotary motor 9. The movable cylinder 11 is fixedly mounted on the side wall of the conical block 10.

[0025] In this embodiment, the cutting fluid mixed with debris is conveyed to the crushing box 1 by the feeding trough 6. The "scraping balls" entangled with debris are further crushed and then enter the solid-liquid separation unit 5 through the bottom wall of the crushing box 1 to separate the solid debris from the cutting fluid. The separated debris enters the recycling stage, and the separated cutting fluid is further filtered to achieve recycling.

[0026] like Figure 4 and Figure 5 As shown, the crushing box 1 is provided with a baffle 29, which is located at the rear end of the crushing box 1, and the fixing cylinder 8 is located inside the baffle 29.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, the upper wall of the fixed cylinder 8 is provided with a flow guide ring 12, which is located near the baffle 29 and extends to the top of the wall of the movable cylinder 11.

[0028] In this embodiment, the chips mixed with cutting fluid in the crushing box 1 are crushed and then slide down close to the baffle 29. Subsequently, they slide down into the movable cylinder 11 by the guide ring 12. The output shaft of the rotary motor 9 drives the conical block 10 and the movable cylinder 11 to rotate, thereby performing solid-liquid separation of solid chips and cutting fluid.

[0029] like Figure 5 and Figure 7 As shown, the outer wall of the movable cylinder 11 is provided with a partition 13, the partition 13 is inclined, and the edge of the partition 13 is movably attached to the inner wall of the fixed cylinder 8.

[0030] like Figure 5 , Figure 6 and Figure 7 As shown, the wall of the movable cylinder 11 is provided with several sets of filter holes 14, and the filter holes 14 are all located above the partition plate 13.

[0031] In this embodiment, the cutting fluid passes through the filter hole 14 under the action of centrifugal force, then falls onto the inclined baffle 13, and flows along the inclined surface of the baffle 13 to the bottom of the baffle 13.

[0032] like Figure 5 As shown, the lower wall of the movable cylinder 11 is provided with a liquid outlet 15, which is located above the partition 13 and is located near the lower end of the inclined surface of the partition 13.

[0033] In this embodiment, the output shaft of the rotary motor 9 drives the conical block 10 and the movable cylinder 11 to rotate. The cutting fluid in the movable cylinder 11 is discharged through the filter hole 14 to the partition 13 on the outer wall of the movable cylinder 11 under the action of centrifugal force, and then discharged from the outlet 15.

[0034] like Figure 5 , Figure 6 and Figure 7 As shown, the lower wall of the movable cylinder 11 is provided with a first discharge port 16, and a solenoid valve 17 is provided at the discharge port.

[0035] like Figure 5 , Figure 6 and Figure 7 As shown, the lower wall of the fixed cylinder 8 is provided with a second discharge port 18, and a discharge pipe 19 is fixedly provided at the second discharge port 18.

[0036] In this embodiment, after the output shaft of the rotary motor 9 drives the conical block 10 and the movable cylinder 11 to rotate, the cutting fluid is discharged through the filter hole 14 under the action of centrifugal force. The chips that have been dehydrated in the movable cylinder 11 are collected at the conical block on the lower wall of the movable sleeve. When the rotary motor 9 stops rotating, the discharge pipe 19 is connected to the first discharge port 16. The first discharge port 16 is opened by the solenoid valve 17, and the chips are discharged from the discharge pipe 19, thereby realizing the recycling of solid chips.

[0037] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the inner wall of the movable cylinder 11 is provided with a spiral guide plate 20, which is set at a 30° rise angle.

[0038] In this embodiment, the debris in the crushing box 1 falls onto the spiral guide plate 20 inside the movable cylinder 11. The spiral guide plate 20 can guide the debris to move along the spiral path when the cylinder rotates, increasing the stroke and tumbling number of the debris during the dehydration process, which can make the cutting fluid in the debris more fully thrown off, improve the dehydration effect, and make the debris drier after the cutting fluid is removed. At the same time, the presence of the spiral guide plate 20 changes the movement mode of the debris in the cylinder. The spiral guide plate 20 pushes the debris to move continuously, maintains uniform distribution, and avoids local accumulation of debris.

[0039] When the moving cylinder 11 rotates, the spiral guide plate 20 can also stir the debris, which helps to break up the agglomerated debris, making it easier for the cutting fluid to be released from the inside of the debris, further improving the solid-liquid separation efficiency, and at the same time making the process of screening out the cutting fluid more uniform.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the crushing box 1 is equipped with a crushing component 21, which is located near the feed inlet 4; The crushing assembly 21 includes a drive motor 22, a drive shaft 23, a driven shaft 24, a breaker hammer 25, and an inner liner plate 26. The drive motor 22 is fixedly mounted on the outer wall of the crushing chamber 1, and the output shaft of the drive motor 22 is movably disposed through the crushing chamber 1. One end of the drive shaft 23 is fixedly mounted on the output shaft of the drive motor 22, and the other end of the drive shaft 23 is movably disposed on the inner wall of the crushing chamber 1 via a bearing. The driven shaft 24 is disposed close to the drive shaft 23, and the driven shaft 24 and the drive shaft 23 are movably connected via a transmission belt. The breaker hammer 25 is detachably mounted on the drive shaft 23 and the driven shaft 24, and the breaker hammer 25 on the drive shaft 23 and the breaker hammer 25 on the driven shaft 24 are tightly engaged. The inner lining plate 26 is provided in two sets. One set of inner lining plate 26 is provided on the lower wall of the feed inlet 4, and the other set of inner lining plate 26 is provided on the upper wall of the feed inlet 4. The surface of the inner lining plate 26 is parallel to the rotating plane of the breaker hammer 25.

[0041] In this embodiment, the output shaft of the drive motor 22 drives the drive shaft 23 to rotate, and the drive shaft 23 drives the driven shaft 24 to rotate through the transmission belt, thereby driving the two sets of breaker hammers 25 to mesh and crush each other, crushing long strips of debris, shaving balls, and large particles of debris.

[0042] In this embodiment, the inner liner 26 can protect the inner wall of the crushing box 1 from the impact of the breaker hammer 25 and the wear of the material, and block the debris generated when the breaker hammer 25 crushes the material, so that the cutting debris is effectively crushed and the debris is difficult to pass through the gap of the inner liner 26.

[0043] like Figure 1 and Figure 2 As shown, a recycling trough 27 is embedded in the lower wall of the feeding trough 6. The upper end of the recycling trough 27 is flush with the lower wall of the feeding trough 6, and the recycling trough 27 is located near the bottom of the chain plate.

[0044] In this embodiment, as some debris passes through the feed chute 6, some cutting fluid seeps along the gaps in the chain plates into the lower wall of the feed chute 6, and then flows along the lower wall of the feed chute 6 into the recovery tank 27. The cutting fluid removed from the recovery tank 27 can be filtered and reused, reducing the waste of cutting fluid.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the CNC machine tool chip removal and cleaning device also includes a filter unit 28. The filter unit 28 is located near the solid-liquid separation unit 5 and is located below the feeding trough 6. The inlet end of the filter unit 28 is connected to the liquid outlet 15.

[0046] In this embodiment, the filter unit 28 is a stainless steel filter element. The filter element has high filtration efficiency and large flow handling capacity. The filter element can be reused, and some filtration performance can be restored through cleaning and backwashing, thus reducing the cost of use.

[0047] It should be noted that, in this document, relational terms such as “first” and “second” are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
