DETAILED DESCRIPTION

[0039] The present application will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0040] like Figure 1-12 As shown, an automatic machining chip collection device includes: a chain conveyor belt 2; one end is located at the chip discharge port of the machine tool, and the other end extends outside the machine tool.

[0041] One end of the chain conveyor belt 2 is located at the chip discharge port at the bottom of the machine tool (such as a lathe), and the other end extends outside the machine tool. When the machine tool is working, the chips fall onto the chain conveyor belt 2 and are transported out as the chain conveyor belt 2 moves, and are finally processed centrally.

[0042] The centrifugal filter drum 3 is arranged below one end of the chain conveyor belt 2 for outputting chips. The function of the centrifugal filter drum 3 is to separate the mixture of chips and coolant. When the mixed chips and coolant enter the centrifugal filter drum 3 together, due to the centrifugal effect, the mixed liquid will be gradually centrifuged and separated from the chips. The separated chips will participate in subsequent collection, and the coolant will be reused after reprocessing.

[0043] A conveying trough 1 and a chain conveyor belt 2 are arranged in the conveying trough 1. An inclined platform is provided at the bottom of the conveying trough 1. A magnetic separation conveyor belt for separating chips from the coolant is provided inside the inclined platform.

[0044] The conveying trough 1 can also be understood as the main body of the entire device, wherein the chain conveyor belt 2 is arranged in the conveying trough 1. The conveying trough 1 has a containing function, which can contain part of the chips and a large amount of coolant to serve as a place for separating the chips and the coolant.

[0045] Some fine chips will be mixed in the coolant. Traditional technology uses filtration to separate the two, but there are two disadvantages. First, fine chips will be stuck in the filter structure and difficult to clean. Second, when too many chips accumulate on the filter, they need to be cleaned, which is very troublesome. In view of the actual situation, this application uses a magnetic conveyor belt to separate the chips in the coolant, thereby avoiding the above two disadvantages. During actual processing, the magnetism of the magnetic conveyor belt absorbs the fine chips in the coolant, causing the fine chips to move along the inclined table and finally separated from the coolant.

[0046] Through the automatic machining chip collection device provided by the present application, the chips generated by machining are gradually transported out of the machine tool under the action of the chain conveyor belt 2, reducing the inconvenience of cleaning the chips at the bottom of the machine tool; at the same time, the coolant attached to the chips is separated by the centrifugal filter cartridge 3, which not only ensures the subsequent normal handling and reprocessing of the chips, but also recycles the coolant to avoid waste; in addition, the coolant is further magnetically separated for fine chips through the magnetic separation conveyor belt, ensuring the cleanliness of the coolant, so that the chips and coolant are separated more fully and thoroughly.

[0047] In some further embodiments, the chain conveyor belt 2 includes a plurality of chain plates 20 hinged to each other, and a surface of the chain plates 20 configured to carry chips is provided with slots 23 .

[0048] The chain plate 20 is a rectangular plate-like structure with a first hinge hole 21 on one side and a second hinge hole 22 on the other opposite side. The second hinge hole 22 is staggered with the first hinge hole 21. When connected, a pin is passed through the first hinge hole 21 and the second hinge hole 22 to achieve the hinge between the two adjacent chain plates 20.

[0049] After the chips are mixed with the coolant, they will become adherent and easily adhere to the chain plate 20. For this reason, in this embodiment, a slot 23 is specially provided on the chain plate 20. The slot 23 can be formed by laser engraving. The aperture of the slot 23 is in the micron level. In other embodiments, the aperture of the slot 23 is preferably 200 microns and the depth is 100 microns. The arrangement of the slots 23 can be arranged in a honeycomb shape. By providing the slots 23, the coolant can form a lubricating film on the surface of the chain plate 20, thereby preventing the chips from always adhering to the chain plate 20 and not falling off.

[0050] A plurality of limiting protrusions 24 are also provided on one side of the chain plate 20 where the slots 23 are provided.

[0051] At the same time, in order to ensure that the chips can move with the chain plate 20, a plurality of limiting protrusions 24 are provided on the chain plate 20. The limiting protrusions 24 are used to limit the chips parallel to the plane of the chain plate 20 to ensure that the chips can move with the chain plate 20.

[0052] The limiting protrusion 24 may be a limiting column.

[0053] It should be noted that the setting of the slot 23 and the setting of the limiting protrusion 24 are not contradictory to each other. The setting of the slot 23 is used to form a lubricating film to weaken the force between the chips and the surface of the chain plate 20 (weaken the adsorption force perpendicular to the surface of the chain plate 20), and the setting of the limiting protrusion 24 is used to enhance the obstruction of the chips from interacting along the plane parallel to the chain plate 20.

[0054] In some further embodiments, a surface of the link plate 20 where the slot 23 is provided is provided with a PTFE coating.

[0055] In order to further reduce the surface energy of the chain plate 20 and reduce the wetting ability of the coolant on the chain plate 20, a PTFE coating is provided on one side of the chain plate 20 where the slot 23 is provided, thereby improving the independence of the lubricating film and preventing the lubricating film from increasing the adhesion of the chips to the chain plate 20.

[0056] In some further embodiments, the conveying trough 1 includes a horizontal conveying section 10, an inclined conveying section 11 and a horizontal discharge section 12; the horizontal conveying section 10 is provided with a feed port, and the horizontal discharge section 12 is provided with a discharge port at one end away from the inclined conveying section 11.

[0057] The conveying trough includes three parts, namely a horizontal conveying section 10, an inclined conveying section 11 and a horizontal discharging section 12, wherein the downstream end of the horizontal conveying section 10 is connected with the upstream end of the inclined conveying section 11, and the downstream end of the inclined conveying section 11 is connected with the upstream end of the horizontal discharging section 12. The inclined conveying section 11 is gradually inclined upward along the conveying direction of the chain conveyor belt 2 to provide a certain height for the chips, which is convenient for the later processing and collection of the chips.

[0058] The receiving port is specifically arranged at the downstream end of the horizontal discharging section 12 .

[0059] The chain conveyor belt 2 using the chain plate 20 is relatively common in the industrial field and is a prior art. In this embodiment, its structure and working principle are not described in detail. For example, the chain plate 20 is conveyed by a sprocket.

[0060] In some further embodiments, the centrifugal filter cartridge 3 includes an annular groove 31 and a rotary filter cartridge 30 , the bottom of the rotary filter cartridge 30 is rotatably connected to the inner edge 312 of the annular groove 31 , and the outer edge 311 of the annular groove 31 is covered on the outside of the rotary filter cartridge 30 .

[0061] The rotary filter drum 30 can rotate relative to the annular groove 31. A filter hole 300 is provided on the side wall of the rotary filter drum 30. When the chips attached with coolant pass through the rotary filter drum 30, under the action of centrifugation, the coolant will pass through the filter hole 300 into the annular groove 31, and the chips will be blocked and finally discharged from the bottom of the rotary filter drum 30.

[0062] The top of the annular groove 31 is open and includes an inner edge 312 and an outer edge 311. There is a groove structure between the inner edge 312 and the outer edge 311, wherein the bottom of the rotary filter drum 30 is rotatably connected to the inner edge 312, that is, the two are arranged to rotate concentrically. The outer edge 311 of the annular groove 31 extends upward and forms a covering for the rotary filter drum 30. The cutting fluid thrown out of the rotary filter drum 30 by centrifugal action will enter the annular groove 31, thereby being separated from the chips.

[0063] In actual practice, a drain pipe is provided at the bottom of the annular groove 31 to recycle the separated coolant.

[0064] Specifically, a connecting ring 313 is provided on the inner side wall of the inner edge 312 of the annular groove 31, and the inner wall of the connecting ring 313 is connected to the inner side wall of the inner edge 312 by bolts, and a stepped groove 314 is provided on the top of the connecting ring 313; correspondingly, a sliding groove 316 is provided on the lower outer side wall of the rotary filter drum 30, and a sliding block 315 is provided on the stepped groove 314. There are multiple sliding blocks 315, and multiple sliding blocks 315 are circumferentially spaced on the stepped groove 314. During installation, the sliding blocks 315 are slid radially inward so that part of the sliding blocks 315 can be located in the sliding groove 316, and at the same time, the sliding blocks 315 and the stepped groove 314 are fitted with each other. At this time, the sliding blocks 315 are fixed to the stepped groove 314 by bolts, so that the sliding fit between the rotary filter drum 30 and the annular groove 31 can be achieved.

[0065] The sliding groove 316 is annular.

[0066] A first motor 32 is provided at the top of the outer edge 311 of the annular groove 31 . A transmission disc 33 is provided at the transmission end of the first motor 32 . A transmission groove 301 is provided at the top of the rotary filter cartridge 30 . The transmission disc 33 engages with the transmission groove 301 .

[0067] The first motor 32 is arranged at the top of the outer edge 311 of the annular groove 31, and the transmission end of the first motor 32 points inward, that is, pointing to the area where the rotary filter drum 30 is located. The transmission disk 33 is arranged on the transmission end of the first motor 32. When the transmission end of the first motor 32 rotates, the transmission disk 33 rotates synchronously. The outer periphery of the transmission disk 33 is provided with a snap-fitting tooth 34, and a transmission groove 301 is correspondingly provided on the top upper edge of the rotary filter drum 30. The snap-fitting tooth 34 on the transmission disk 33 is engaged with the transmission groove 301. When the transmission disk 33 rotates, it can drive the rotary filter drum 30 to rotate synchronously, thereby realizing the centrifugal effect.

[0068] In some further embodiments, the centrifugal filter cartridge 3 is arranged at an angle.

[0069] The inclined centrifugal filter drum 3 allows the chips to flow downward while being subjected to centrifugal action. If the centrifugal filter drum 3 is set horizontally, the chips cannot be discharged. If the centrifugal filter drum 3 is set vertically, most of the chips cannot be subjected to centrifugal action and the coolant cannot be separated. The inclined centrifugal filter drum 3 can ensure that the chips can be subjected to a certain centrifugal force, and can also ensure that the chips can fall under the action of gravity, thereby effectively realizing the separation of chips and coolant.

[0070] From the feed port of the rotary filter drum 30 to the discharge port, the diameter of the rotary filter drum 30 gradually decreases.

[0071] The diameter of the rotary filter drum 30 gradually decreases along the direction from chip feeding to chip discharging. Firstly, the open-mouthed rotary filter drum 30 makes it easier for chips to enter. Secondly, as the diameter gradually decreases, the centrifugal force on the chips gradually decreases (F=mω²r), so the chips are more likely to fall out of the rotary filter drum 30 at this point.

[0072] An outer edge 311 of the annular groove 31 is connected to a side wall of the horizontal discharge section 12 .

[0073] The entire centrifugal filter cartridge 3 is connected to the outer side wall of the conveying trough 1 through a connecting arm 310. Specifically, one end of the connecting arm 310 is connected to the outer wall of the outer edge 311 of the annular groove 31 by bolts, and the other end is connected to the side wall of the horizontal discharge section 12 in the conveying trough 1 by bolts.

[0074] By loosening the bolts, the height and tilt angle of the centrifugal filter cartridge 3 can be adjusted.

[0075] In some further embodiments, the horizontal discharge section 12 is rotatably provided with a cleaning roller 13 , and a cleaning brush 130 is provided on the outer peripheral wall of the cleaning roller 13 , and the tangential direction of the rotation direction of the cleaning brush 130 is opposite to the conveying direction of the chain plate 20 .

[0076] A cleaning brush 130 is provided on the cleaning roller 13 . When the cleaning brush 130 rotates, it can sweep off some of the chips attached to the chain plate 20 and drop them into the centrifugal filter drum 3 from the discharge port of the horizontal discharge section 12 .

[0077] The cleaning roller 13 is specifically located below the rotation of the chain conveyor belt 2, that is, below one of the rotary sprockets. The rotary sprocket and the cleaning roller 13 can be connected by a chain sprocket (or belt, pulley), so as to achieve the reverse movement of the two.

[0078] In some further embodiments, a trolley 4 is further included, and the trolley 4 is located below the centrifugal filter cartridge 3 .

[0079] The trolley 4 is located below the centrifugal filter drum 3 and is used to receive the chips dropped from the rotary filter drum 30 . The bottom of the trolley 4 is provided with rollers to enable the trolley 4 to move, thereby facilitating the transfer of the chips.

[0080] In some further embodiments, the table top of the inclined platform is a plastic board; a cavity 6 is provided inside the inclined platform, the cavity 6 is open at the bottom of the conveying trough 1, and a rotating roller 61 and a power roller 62 are provided in the cavity 6; the magnetic separation conveyor belt includes a transmission belt 60 and a permanent magnet; the transmission belt 60 is wound around the rotating roller 61 and the power roller 62, and the number of permanent magnets is multiple, and multiple permanent magnets are connected to the end of the transmission belt 60 facing away from the power roller 62.

[0081] The bottom of the conveying trough 1 protrudes upward to form an inclined platform, and the top surface of the inclined platform is inclined. During daily operation, the relatively lower part is submerged in the coolant to be recovered, and the relatively higher part is located outside the coolant.

[0082] The interior of the ramp is in a cavity 6 state, and the bottom of the cavity 6 is open to the bottom of the conveying trough 1 , and the opening is used to set components into the cavity 6 .

[0083] The cross section of the cavity 6 inside the ramp can be regarded as an obtuse triangle, in which the hypotenuse is the top surface of the ramp. In particular, the top surface of the ramp is a plastic plate. In other embodiments, the top surface of the ramp can also be some antimagnetic material (or paramagnetic material stainless steel plate).

[0084] A rotating roller 61 and a power roller 62 are provided in the cavity 6, wherein the power roller 62 is driven to rotate by a second motor arranged on the outer wall of the conveying trough 1, and the transmission belt 60 is wound around the rotating roller 61 and the power roller 62. When the second motor drives the power roller 62 to rotate, the transmission belt 60 will move synchronously.

[0085] In actual situations, there are two rotating rollers 61 and one power roller 62 .

[0086] The permanent magnets are arranged on the transmission belt 60, which can be connected by bonding. There are multiple permanent magnets, and multiple permanent magnets are arranged at intervals on the transmission belt 60. The transmission belt 60 between one rotating roller 61 and the power roller 62 is parallel to the top surface of the inclined table. The permanent magnets on this section are located between the top surface and the transmission belt 60. Under the action of magnetism, some chips will be adsorbed from the coolant on the top surface of the inclined table. Then, as the transmission belt 60 equipped with permanent magnets continues to move, the adsorbed chips will rise along the coordinated top surface until they reach the top of the inclined table, which is above the rotation position of the transmission belt 60.

[0087] By setting up the inclined table and the magnetic separation conveyor belt, some of the chips remaining in the coolant will be adsorbed and separated, so that the coolant in the conveying trough 1 is purer, thereby reducing the difficulty of subsequent processing.

[0088] In some further embodiments, a material drop opening is provided on the side wall of the conveying trough 1 , and the material drop opening is correspondingly arranged at the top of the inclined platform; a material receiving trough 5 is clamped on the material drop opening.

[0089] A drop opening is provided on the side wall of the conveying trough 1, which is located at the top of the inclined platform. The chips attracted by the permanent magnet will fall out of the conveying trough 1 through the drop opening. In order to facilitate the collection of the chips, a receiving trough 5 is also provided on the drop opening.

[0090] A snap-fit ​​groove is provided on the side wall of the conveying trough 1, and the snap-fit ​​groove is located above the material drop port. A snap-fit ​​plate 50 is provided above the material receiving trough 5. When placing the material receiving trough 5, first make the height of the snap-fit ​​plate 50 higher than the height of the snap-fit ​​groove, and then slide the material receiving trough 5 downward to achieve the snap-fit ​​connection between the snap-fit ​​plate 50 and the snap-fit ​​groove.

[0091] In order to ensure the stability of the material receiving trough 5, a limit handle 51 is provided on both sides of the material receiving trough 5. The limit handle 51 is provided with a notch 510 facing downward. Correspondingly, two adjusting bolts 101 are screwed on the side wall of the conveying trough 1. When the material receiving trough 5 slides downward to achieve the matching of the clamping groove and the clamping plate 50, the notch 510 on the limit handle 51 just matches the adjusting bolt 101. After that, the adjusting bolt 101 is tightened to lock the limit handle 51 on the side wall of the conveying trough 1.

[0092] Working principle:

[0093] Chips generated during machining enter trough 1 from above the horizontal conveying section 10, i.e., the feed port. They fall onto chain conveyor 2, along with the coolant used to cool the workpiece and tool tip. Chips and coolant fall together onto chain conveyor 2, with some chips potentially splashing onto the outside of chain conveyor 2 and onto the bottom of trough 1. The coolant then drips down through chain conveyor 2 into the interior of trough 1, mixing with the chips that splashed onto the outside of chain conveyor 2 and onto the bottom of trough 1.

[0094] As the chain conveyor 2 moves, the chips and part of the coolant will be continuously transported, and the direction of transportation is: the horizontal conveying section 10 to the inclined conveying section 11 and then to the horizontal discharge section 12, while rising in sequence. The chain conveyor 2 rotates at the end of the horizontal discharge section 12 away from the inclined conveying section 11. During the rotation, due to the presence of the micron-level slots 23, the coolant forms a lubricating film on the surface of the chain plate 20, thereby greatly reducing the adhesion between the chips and the chain plate 20, ensuring that the chips fall smoothly from the chain plate 20. At the same time, the limiting protrusion 24 can ensure that the chips can move with the chain plate 20 in the inclined conveying section 11, thereby ensuring the function of the chain conveyor 2.

[0095] The chips with coolant attached will then fall into the rotating filter drum 30. As the rotating filter drum 30 rotates, the coolant on the chips will pass through the filter holes 300 and enter the annular groove 31. The coolant entering the annular groove 31 can be discharged from the bottom of the annular groove 31 through the drain pipe for reuse.

[0096] The cleaning roller 13 provided on the horizontal discharge section 12 of the chain conveyor 2 can clean the chain plate 20 during the rotation process and simultaneously sweep the unfallen chips from the chain plate 20 to drop into the centrifugal filter drum 3 .

[0097] When the magnetic separation conveyor belt rotates, the permanent magnet will adsorb some of the chips in the coolant. As the transmission belt 60 continues to move, the adsorbed chips will move upward along the top surface of the inclined table until they reach the top drop-out port. As the transmission belt 60 rotates, the chips that reach the drop-out port will no longer be affected by the adsorption effect of the permanent magnet, and will enter the receiving trough 5 through the drop-out port to achieve separation from the coolant.

[0098] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
