[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention 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, and therefore should not be construed as a limitation of this invention.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0038] The following is combined Figures 1 to 9 The remote milling machine chip collection system 10 provided in this embodiment will be described in detail.

[0039] Please refer to Figure 1 An embodiment of the present invention provides a long-distance milling machine chip collection system 10, including a positive and negative pressure device 100, a chip conveying pipe 200, a negative pressure tank 300, a chip collection device 400, and a settling box 500. The positive and negative pressure device 100 is used for blowing or exhausting air; one end of the chip conveying pipe 200 is connected to the milling machine 11, and the other end of the chip conveying pipe 200 is connected to the positive and negative pressure device 100; the negative pressure tank 300 is fixed on the chip conveying pipe 200, and a settling hole 310 is provided at the bottom of the negative pressure tank 300; the negative pressure tank 300... The device 0 is used to allow the lighter portion of the iron filings flowing into the negative pressure tank 300 to flow into the iron filings conveying pipe 200, while the heavier portion settles into the settling hole 310; the filings collection device 400 is connected to the settling hole 310 and is used to collect the iron filings falling from the settling hole 310; the settling box 500 is fixed on the iron filings conveying pipe 200 and connected between the negative pressure tank 300 and the positive and negative pressure device 100. The settling box 500 is equipped with multiple buffer wind speed sections, which are used to allow the iron filings flowing into the settling box 500 to settle within the settling box 500.

[0040] It should be noted that the terms "heavier" and "lighter" are relative and only comparable within the same space. For example, the heavier and lighter portions of iron filings inside the negative pressure tank 300 refer to the relatively heavier and lighter portions of the iron filings flowing into the negative pressure tank 300 as a whole.

[0041] The positive and negative pressure device 100 can be a negative pressure generator, a dust collector, an industrial vacuum cleaner, or other equipment capable of generating negative pressure. It can also be used in conjunction with a blower to create both negative and positive pressure within the iron filings conveying pipe 200. In this embodiment, the positive and negative pressure device 100 uses a blower capable of blowing in either the forward or reverse direction.

[0042] When the blower rotates in the forward direction, it can draw air, creating a negative pressure within the chip conveying pipe 200. The chips on the milling machine 11 are drawn to the negative pressure tank 300 through the chip conveying pipe 200. The air velocity in the negative pressure tank 300 decreases. Within the negative pressure tank 300, the chips are affected by the airflow. Lighter chips continue to flow towards the settling box 500, while heavier chips flow through the settling hole 310 to the chip collection device 400. The chips in the chip collection device 400 can be used for carbon, sulfur, oxygen, and nitrogen analysis. The settling box 500 is equipped with multiple buffer wind speed sections. These sections reduce the air velocity within the settling box 500, causing the iron filings flowing towards it to slow down and settle to the bottom, requiring periodic manual cleaning. The settling of iron filings to the bottom of the settling box 500 prevents lighter iron filings from entering the positive / negative pressure device 100 under negative pressure or entering the iron filings conveying pipe 200 under positive pressure, thus contaminating the next batch of slag samples and improving the accuracy of the test. The end of the iron filings conveying pipe 200 connected to the milling machine 11 can simultaneously connect to multiple iron filings collection stations on the milling machine 11, collecting iron filings generated at multiple stations at the same time. It can also be used for suction during milling machine 11 operation.

[0043] After milling is completed on milling machine 11, the blower can continue to suck for a period of time before stopping and reversing its motion to blow air into the chip conveying pipe 200, blowing the chips from the chip conveying pipe 200 toward milling machine 11. This prevents the chip material in the chip conveying pipe 200 from mixing with the chip sample of the subsequent test, which would lead to inaccurate test results.

[0044] The scrap conveying pipe 200 enables long-distance centralized collection of scrap from multiple workstations, saving workers time in collecting materials from multiple collection points to the analysis equipment; while the milling machine 11 is milling samples, it can simultaneously draw scrap samples into the equipment, saving time and improving work efficiency; in addition, the negative pressure tank 300 and the settling box 500 perform two settling processes to prevent sample mixing and contamination.

[0045] The positive and negative pressure device 100 and the iron chip conveying pipe 200 can be selected according to the transmission distance to realize the transmission of chip samples over different distances.

[0046] Reference Figure 1 In this embodiment, there is at least one iron chip conveying pipe 200, at least one negative pressure tank 300, and at least one settling box 500; at least one iron chip conveying pipe 200, at least one negative pressure tank 300 and at least one settling box 500 are connected in a one-to-one correspondence; the settling holes 310 of at least one negative pressure tank 300 are all connected to the chip collection device 400.

[0047] The scrap conveying pipe 200 can be equipped with one, two, or three or more pipes, which can simultaneously collect scrap from more workstations.

[0048] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the negative pressure tank 300 is provided with a first air hole 320 and a second air hole 330; the first air hole 320 is used to communicate with the milling machine 11; the second air hole 330 is used to communicate with the settling box 500; the height of the first air hole 320 to the settling hole 310 is lower than the height of the second air hole 330 to the settling hole 310.

[0049] Iron filings are drawn in through the first air vent 320. Under the influence of the airflow within the negative pressure tank 300, the lighter portion of the iron filings flows to the second air vent 330, while the heavier portion flows to the settling vent 310. This completes the first screening of the iron filings.

[0050] The position of the first air hole 320 is lower than that of the second air hole 330, which can prevent iron filings from being sucked away by the second air hole 330 as soon as they enter the negative pressure tank 300. The height difference between the second air hole 330 and the first air hole 320 allows the iron filings to have room to flow after entering the negative pressure tank 300, so that the iron filings can move fully under the action of airflow, thereby screening out the lighter iron filings that flow out from the second air hole 330, while the heavier ones settle into the settling hole 310.

[0051] Specifically, the first air vent 320 is located at the top of the negative pressure tank 300, corresponding to the position of the settling hole 310, and the height of the first air vent 320 is higher than that of the settling hole 310. The second air vent 330 is located at the top of the side wall of the negative pressure tank 300.

[0052] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the bottom edge of the negative pressure tank 300 is inclined to the bottom center to form a tapered outlet with a cross-section that gradually decreases from top to bottom. The settling hole 310 is opened in the center of the tapered outlet. The tapered outlet is used to guide the iron filings to gather in the settling hole 310 under the action of gravity.

[0053] Specifically, the bottom wall of the negative pressure tank 300 is conical, and the iron filings that are not screened out by the second air hole 330 settle downwards and flow along the conical surface to the settling hole 310. The conical outlet has the function of guiding and collecting.

[0054] Reference Figure 5 and Figure 6In this embodiment, the chip collection device 400 includes a chip collection platform 410, a collection pipe 420, a first pushing mechanism 430, and a second pushing mechanism 440. The collection pipe 420 is fixed on the chip collection platform 410, one end of the collection pipe 420 is connected to the settling hole 310, and the other end of the collection pipe 420 is used to output sludge to the slag cup 480 located at the first station 411. The first pushing mechanism 430 is fixed on the chip collection platform 410 and is used to push the slag cup 480 located at the first station 411 to seal or detach from the collection pipe 420. The second pushing mechanism 440 is used to push the slag cup 480 from the second station 412 to the first station 411, and to push the slag cup 480 from the first station 411 to the third station 413. The first station 411 is located between the second station 412 and the third station 413.

[0055] Initially, the first pushing mechanism 430 pushes an empty slag cup 480 to seal it against the collection pipe 420. Then, iron filings that have settled in the settling hole 310 within the negative pressure tank 300 enter the slag cup 480 along the collection pipe 420. Once the slag cup 480 is full, the second pushing mechanism 440 pushes the full slag cup 480 to the third station 413, awaiting manual collection. Simultaneously, after the second pushing mechanism 440 retracts, it can also push the empty slag cup 480 located at the second station 412 to the first station 411, awaiting the first pushing mechanism 430 to engage with the collection pipe 420 to collect the slag. This process is repeated. The third station 413 is used to place empty slag cups 480, the first station 411 is used to place slag cups 480 awaiting loading, and the second station 412 is used to place full slag cups 480. The power components for the first pushing mechanism 430 and the second pushing mechanism 440 can be pneumatic cylinders or electric cylinders. It enables continuous collection of sediment into different slag cups 480 for centralized processing, which is safe and efficient.

[0056] Reference Figure 5 and Figure 6 In this embodiment, the collection pipe 420 is arranged vertically; the first pushing mechanism 430 is located below the collection pipe 420. The first pushing mechanism 430 is used to push the slag cup 480 located at the first station 411 to move up and down so that the slag cup 480 is attached to or detached from the collection pipe 420.

[0057] The first station 411 is located below the collection pipe 420. The slag cup 480, pushed from the second station 412 to the first station 411, is pulled upwards by the first pushing mechanism 430 until it is flush with the bottom of the collection pipe 420. After the slag is collected, the first pushing mechanism 430 pulls the slag cup 480 downwards, and then the second pushing mechanism 440 pushes the slag cup 480 to the third station 413. The second pushing mechanism 440 can simultaneously push the empty slag cup 480 at the third station 413 to the first station 411, and simultaneously push the empty slag cup 480 at the first station 411 to the third station 413.

[0058] Reference Figure 5 and Figure 6 In this embodiment, the chip collection platform 410 includes a first storage channel 450 fixed to the second station 412, a second storage channel 460 fixed to the third station 413, and an inclined channel 470 connecting the first station 411 and the third station 413. The first storage channel 450 is used to stack multiple empty slag cups 480, and the inclined channel 470 guides the slag cups 480 to slide towards the third station 413. The second pushing mechanism 440 includes a pushing plate 441 and a support plate 442 fixed at an angle. The pushing plate 441 is used to push the slag cups 480 located below on the second station 412, and the support plate 442 supports the slag cups 480 located above. The pushing plate 441 is also used to push the slag cups 480 located at the first station 411 to the inclined channel 470.

[0059] The first receiving channel 450 stacks multiple empty slag cups 480 from top to bottom. The push plate 441 of the second pushing mechanism 440 pushes the slag cup 480 located below to the first station 411. At the same time, the support plate 442 supports the slag cup 480 located above. After the second pushing mechanism 440 retracts, the slag cup 480 located above will fall to the third station 413 without the support of the support plate 442, waiting for the second pushing mechanism 440 to push it to the first station 411 for receiving.

[0060] Reference Figure 5 and Figure 6 In this embodiment, the chip collection device 400 also includes a computer 600 and a card reader 610; the card reader 610 is fixed at the second work station 412 and is used to read the information of the slag cup 480 that has moved to the second work station 412 and transmit it to the computer 600 for archiving.

[0061] Specifically, the card reader 610 is fixed at the second station 412, located below the first storage channel 450. Empty slag cups 480 located above fall from the first storage channel 450 onto the card reader 610, where information can be read. Each slag cup 480 has a chip that can be read by the card reader 610, and the computer 600 automatically records the code for easy archiving.

[0062] Reference Figure 7 , Figure 8 and Figure 9 In this embodiment, the settling box 500 includes a box body 510 and multiple baffles; the top of the box body 510 is provided with a third air hole 511 and a fourth air hole 512; the fourth air hole 512 is connected to the positive and negative pressure device 100, and the third air hole 511 is connected to the negative pressure tank 300; multiple baffles are fixed inside the box body 510, and the multiple buffer wind speed sections include a first buffer wind speed section 550, a second buffer wind speed section 560 and a third buffer wind speed section 570 formed by multiple baffles and interconnected; the first buffer wind speed section 550 is connected to the third air hole 511, the second buffer wind speed section 560 is connected to the fourth air hole 512; the third buffer wind speed section 570 is located at the bottom of the box body 510.

[0063] Under negative pressure, the iron filings exiting from the second air vent 330 of the negative pressure tank 300 enter the first buffer air velocity section 550, the second buffer air velocity section 560, and the third buffer air velocity section 570 through the third air vent 511. After multiple speed reductions, they settle at the bottom of the settling box 500 and can be used for subsequent testing. They will not enter the positive and negative pressure device 100. Under positive pressure, the positive and negative pressure device 100 blows air into the negative pressure tank 300. The iron filings are buffered and settled between the first buffer air velocity section 550, the second buffer air velocity section 560, and the third buffer air velocity section 570, and will not flow out of the third air vent 511, thus preventing contamination of the next slag sample. The settling box 500 completes the second screening of iron filings after the negative pressure tank 300.

[0064] Reference Figure 7 , Figure 8 and Figure 9 In this embodiment, the multiple baffles include a first baffle 520, a second baffle 530, and a third baffle 540. The first baffle 520 and the second baffle 530 are fixed at an angle to two opposite inner sidewalls of the housing 510, and the distance between the first baffle 520 and the second baffle 530 gradually decreases from top to bottom. The third baffle 540 is fixed between the third air hole 511 and the fourth air hole 512 at the top of the housing 510, and is located between the first baffle 520 and the second baffle 530. A first buffer wind speed section 550 is formed between the third baffle 540 and the first baffle 520, a second buffer wind speed section 560 is formed between the third baffle 540 and the second baffle 530, and a third buffer wind speed section 570 is formed below the first baffle 520 and the second baffle 530.

[0065] by Figure 9 The relative positions of the first baffle 520 and the second baffle 530 are described. When the blower is drawing air in the forward direction, the iron filings enter from the third air hole 511 between the third baffle 540 and the first baffle 520, and then flow between the third baffle 540 and the second baffle 530. After being buffered and slowed down, they settle down below the first baffle 520 and the second baffle 530.

[0066] According to the remote milling machine chip collection system 10 provided in this embodiment, the working principle of the remote milling machine chip collection system 10 is as follows:

[0067] When the milling machine 11 starts milling the sample according to the program signal, the blower starts working. The blower generates negative pressure from the settling box 500 to the negative pressure tank 300. The chip-like sample generated by the milling machine 11 passes through the chip conveying pipe 200 to the negative pressure tank 300. The chip-like sample falls from the negative pressure tank 300 onto the chip collection device 400, completing the first settling. The lighter iron chips in the negative pressure tank 300 continue to flow to the settling box 500 to complete the second settling. After the milling machine 11 finishes milling, the blower continues to suck for a period of time before stopping to prevent the material stored in the chip conveying pipe 200 from mixing with the chip-like sample of the subsequent sample, which would lead to inaccurate test results.

[0068] The first pushing mechanism 430 of the chip collection device 400 retracts, causing the slag cup 480 at the first station 411 to descend. The second pushing mechanism 440 drives the pushing plate 441 to push the slag cup 480 at the second station 412 onto the slag cup 480 at the first station 411, which in turn moves to the third station 413. The second pushing mechanism 440 retracts, and the slag cup 480 at the second station 412 falls freely onto the card reader 610. The slag cup 480 has a chip, which the card reader 610 automatically reads and records on the computer 600. The first pushing mechanism 430 lifts the empty slag cup 480 at the first station 411, ensuring a tight seal between the slag cup 480 and the sealing ring 421 at the bottom of the collection pipe 420 to prevent air leakage. Finally, the blower starts back-blowing to prevent chip residue from remaining in the chip conveying pipe 200.

[0069] The long-distance milling machine chip collection system 10 provided in this embodiment has at least the following advantages:

[0070] The positive and negative pressure device 100 generates negative pressure, enabling long-distance centralized collection of iron filings from multiple workstations, saving workers time spent retrieving materials from multiple collection points and transporting them to the analysis equipment. It can quickly and effectively collect iron filings generated during the milling machine 11's machining process, improving production efficiency and reducing manual labor intensity. The positive and negative pressure device 100 also blows air to clean the iron filings within the iron filings conveying pipe 200, ensuring that the iron filings collected in this batch are not mixed with those collected in the next. The process is automated through a program, meeting the needs of industrial automation.

[0071] The milling machine 11 is connected by a chip conveying pipe 200, which simultaneously picks up chip samples from the milling machine 11 while it is milling, saving time and improving work efficiency. It also saves workers the time spent moving back and forth between multiple milling machines 11.

[0072] The negative pressure tank 300 performs the first sedimentation separation of iron filings, and the settling box 500 performs the second sedimentation separation of iron filings. Through two sedimentation processes, iron filings contamination is prevented, and mixed samples are less likely to occur, resulting in iron filings that meet the standards.

[0073] The 480 automatic slag cup changer has multiple waiting positions, enabling continuous operation and improving production efficiency.

[0074] The chip and card reader automatically record slag sample information. Each slag cup 480 has a chip, and the code can be automatically recorded by the card reader 610 and the computer 600 for easy archiving. This allows for centralized archiving and classification of iron filings from multiple workstations in one operation.

[0075] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
