[0002] The intelligent metal detection equipment is an automated detection system designed specifically for processing non-woven products. Combining technologies such as electromagnetic sensing, artificial intelligence, and the Internet of Things, it can detect and remove metal impurities (such as broken needles, metal chips, etc.) in raw materials or finished products in real time.

[0003] In order to increase the detection range of the metal detector, the width of general metal detectors is relatively large, which increases the number of coils inside the metal detector.

Detailed implementation manners

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] As Figures 1 to 4 shown, an intelligent metal detection device for processing non-woven products proposed by the present invention includes a frame 1 and a metal detector 2 fixedly installed on the frame 1. A plurality of groups of coils 201 are fixedly installed in the metal detector 2. The coils 201 are the main components of the metal detector 2, which directly determine the detection sensitivity, accuracy and anti-interference ability. The coils 201 generate an alternating electromagnetic field through high-frequency alternating current to form a dynamic magnetic field covering the detection area. This embodiment also includes a first contact 202 fixedly installed on the coils 201, and a plurality of groups of second contacts 203 are slidably installed in the metal detector 2. When the first contact 202 contacts the second contact 203, the circuit where the coils 201 are located is connected. When the first contact 202 and the second contact 203 are not in contact, the coils 201 will be open-circuited, which can achieve the effect of energy saving. The circuit connection method of the coils 201 is prior art and will not be elaborated here.

[0020] As shown Figures 5 to 10 in the figure, this embodiment further includes a support rod member 5 installed on the rack 1. The support rod member 5 includes multiple groups of pressure sensing components corresponding to the coils 201 one by one. When the pressure sensing component bears pressure, it drives the first contact 202 and the second contact 203 to contact. The non-woven fabric 8 will contact the support rod member 5 and apply a certain pressure to the support rod member 5. Then, the pressed area on the support rod member 5 is the area where the non-woven fabric 8 exists. Only this area needs to be inspected, and the coils 201 in the remaining areas can be opened to achieve the purpose of energy saving.

[0021] Furthermore, the support rod member 5 includes a support cylinder 501 rotatably installed on the rack 1. The pressure sensing component includes multiple groups of sliding rods 502 slidably installed in the support cylinder 501. A bearing plate 503 is fixedly installed on a group of sliding rods 502. A guide rod 519 coaxially arranged with the support cylinder 501 is fixedly installed on the rack 1. Two pressing blocks 504 are slidably installed on the guide rod 519. A connecting rod 505 is rotatably installed between the pressing block 504 and the sliding rod 502. A driving cylinder 506 is fixedly installed on the guide rod 519 and located between the two pressing blocks 504. When detecting the non-woven fabric 8, the non-woven fabric 8 will be in a tensioned state and cover the bearing plate 503 and apply a certain pressure to the bearing plate 503. Therefore, the bearing plate 503 in contact with the non-woven fabric 8 will be squeezed and move along the axial direction of the sliding rod 502. The squeezed bearing plate 503 will contract towards the direction close to the guide rod 519, and under the action of the connecting rod 505 and the pressing block 504, multiple bearing plates 503 will move synchronously. The non-woven fabric 8 can move smoothly on the circle formed by the bearing plates 503. The compressed bearing plate 503 will drive the pressing block 504 to move through the transmission of the connecting rod 505.

[0022] Among them, two sealing plates 507 are slidably installed in the driving cylinder 506. A first sealing sheet 508 that can expand and contract along the axial direction of the driving cylinder 506 is fixedly installed between the sealing plate 507 and the driving cylinder 506. Generally, existing seals are sealed by installing sealing rings, but there will be a certain frictional force between the sealing ring and the driving cylinder 506, which makes the non-woven fabric 8 need to apply a greater pressure to the bearing plate 503, and then the tension of the non-woven fabric 8 needs to be increased. Excessive tension may damage the non-woven fabric. This structure can effectively reduce the occurrence of this problem. Multiple pressing rods 509 are fixedly installed on the pressing block 504, and the pressing rods 509 are fixedly connected to the adjacent sealing plate 507. An execution component that drives the second contact 203 to move according to the volume change between the two sealing plates 507 is installed in the metal detector 2. When the pressing block 504 moves, the two sealing plates 507 on both sides can be driven to approach each other through the transmission of the pressing rods 509, thereby reducing the volume between the two sealing plates 507.

[0023] Further, the execution component includes an execution cylinder 510 fixedly installed inside the metal detector 2. A blocking block 511 is slidably installed inside the execution cylinder 510. A second sealing piece 512 is installed between the blocking block 511 and the execution cylinder 510, which can block the gap between the execution cylinder 510 and the blocking block 511. A first spring 513 is fixedly installed between the blocking block 511 and the execution cylinder 510. A driving rod 514 is fixedly installed on the blocking block 511, and a driving plate 515 is fixedly installed on the driving rod 514. The second contact 203 is fixedly connected to the driving plate 515. The execution cylinder 510 and the driving cylinder 506 are connected through a pipeline 516. The pipeline 516, the execution cylinder 510, and the driving cylinder 506 are all filled with a hydraulic medium, and the hydraulic medium is a liquid that cannot be compressed under the working environment. When the two sealing plates 507 approach each other, the hydraulic medium inside the driving cylinder 506 will move to the inside of the execution cylinder 510 through the pipeline 516, thereby driving the blocking block 511 to move downward, and then driving the driving plate 515 to move downward, so that the second contact 203 contacts the first contact 202, making the coil 201 energized, and then the area of the non-woven fabric 8 can be automatically judged and the coil 201 in the corresponding area can be turned on.

[0024] It should be noted that a plurality of sliding cylinders 517 are rotatably installed on the sealing plate 507. A sliding rod 518 is slidably installed inside the sliding cylinder 517, and the sliding rod 518 is rotatably connected to the inner wall of the driving cylinder 506. Since the first sealing piece 508 has elasticity and a certain elasticity, under the action of hydraulic pressure, the first sealing piece 508 will expand outward, thereby releasing the volume between the two sealing plates 507. Through the arrangement of the sliding cylinder 517 and the sliding rod 518, the first sealing piece 508 can be attached to the sliding rod 518 when being pressed, thereby preventing the first sealing piece 508 from expanding outward.

[0025] As Figures 11 to 15 shown, in this embodiment, a transition detection component 6 is installed between adjacent two groups of pressure sensing components. When the transition detection component 6 detects that the pressure borne by the pressure sensing component is insufficient, it drives the first contact 202 to contact the second contact 203. It should be noted that the detection area of a group of coils 201 is the detection area 7, and a part of the detection areas of adjacent two groups of coils 201 will overlap, and the overlapping area is the overlapping area 701. The overlapping area should not be too large, otherwise it will reduce the detection area of the coils 201 and increase the energy consumption; Refer to Figure 11 , the position distribution of the non-woven fabric 8 has the following situations: The non-woven fabric 8 completely covers the bearing plate 503; The non-woven fabric 8 does not completely cover the entire bearing plate 503, but covers half or more of the bearing plate 503; The non-woven fabric 8 crosses a group of bearing plates 503 and is located inside the overlapping area 701 without extending to the next group of bearing plates 503; The non-woven fabric 8 passes over the bearing plate 503 and the overlapping area 701, and makes a small-range coverage of the edges of the next set of bearing plates 503. In this case, the non-woven fabric 8 may not exert sufficient pressure on this set of bearing plates 503, resulting in the inability of this set of bearing plates 503 to contract, and the edges of the non-woven fabric 8 cannot be detected, that is, the pressure sensing component bears insufficient pressure. At this time, the transition detection component 6 actively applies a contraction force to this set of bearing plates 503.

[0026] Further, the transition detection component 6 includes a coincidence plate 601 fixedly installed on the guide rod 519 and adjacent to the two bearing plates 503. The coincidence plate 601 is located within the overlapping area 701. A plurality of connecting columns 602 are slidably installed at both ends of the bearing plate 503. A rotating rod 603 is rotatably installed on the connecting column 602. A positioning rod 604 is slidably installed on two adjacent rotating rods 603 located on the two bearing plates 503. The positioning rod 604 is rotatably connected to the coincidence plate 601 through a connecting seat 605. Lifting components that move as the rotating rod 603 moves up and down are installed at both ends of the bearing plate 503. When the bearing plates 503 on both sides contract synchronously, the rotating rod 603 and the positioning rod 604 will move synchronously. At this time, the rotating rod 603 will not tilt. However, when one of the bearing plates 503 does not contract, the rotating rod 603 will tilt, and the rotating rod 603 closer to the non-contracting bearing plate 503 will rise.

[0027] Among them, the jacking assembly includes a plurality of slideways 606 fixedly installed at both ends of the bearing plate 503. A push rod 607 is slidably installed in the slideway 606. A circular plate 608 is fixedly installed on the push rod 607. A plurality of boxes 609 corresponding to the circular plates 608 one by one are slidably installed on the bearing plate 503. An elastic member is installed between the box 609 and the bearing plate 503. A roller 613 is rotatably installed at the bottom of the box 609. Under the action of the elastic member, the roller always abuts against the rotating rod 603. Thus, when the rotating rod 603 rises, the box 609 will be driven to rise. A second spring 610 is fixedly installed between the circular plate 608 and the box 609. A third contact 611 is fixedly installed on the circular plate 608. A fourth contact 612 is fixedly installed in the box 609. Two sealing plates 507 in the same driving cylinder 506. An electromagnet 614 is fixedly installed on one of the sealing plates 507, and an iron block 615 is fixedly installed on the other sealing plate 507. When the third contact 611 and the fourth contact 612 are connected, the circuit where the electromagnet 614 is located is connected. When the box 609 rises, the push rod 607 will be driven to rise synchronously. When the non-woven fabric 8 covers the bearing plate 503, the push rod 607 will be limited, so that the push rod 607 cannot rise. At this time, the continuously rising box 609 will compress the second spring 610 and make the third contact 611 and the fourth contact 612 contact. At this time, the electromagnet 614 generates a magnetic force to adsorb the iron block 615, thereby energizing the corresponding coil 201.

[0028] As Figures 1 to 4 As shown, in this embodiment, guide tubes 3 are rotatably installed on both sides of the frame 1. A first transmission belt 301 is fixedly installed between the two guide tubes 3. A first motor 302 is fixedly installed on the frame 1. The output shaft of the first motor 302 is coaxially and fixedly connected to one of the guide tubes 3. By the first motor 302, the non-woven fabric 8 can be driven to move, and the rotation speed should be equal to the moving speed of the non-woven fabric 8, which can effectively prevent wear between the non-woven fabric 8 and the guide tubes 3.

[0029] A support tube 4 is rotatably installed on the frame 1. A second transmission belt 401 is fixedly installed between the support tube 4 and the support cylinder 501. A second motor 402 is fixedly installed on the frame 1. The output shaft of the second motor 402 is coaxially and fixedly connected to one of the support tubes 4. By the second motor, the support tube 4 and a plurality of bearing plates 503 can be rotated synchronously, preventing relative movement between the non-woven fabric and the support tube 4 and the bearing plates 503, resulting in wear problems.

[0030] As Figures 1 to 3As shown, in this embodiment, a tensioning tube 9 is slidably and rotatably mounted on the frame 1. A linear motor 901 is fixedly mounted on the frame 1. The output shaft of the linear motor 901 is rotatably connected to the tensioning tube 9. A tube pressing member 902 is rotatably mounted on the frame 1. A fastening tube 903 is slidably mounted on the frame 1. A support block 904 is fixedly mounted on the frame 1. A third spring 905 is fixedly mounted between the fastening tube 903 and the support block 904. A screw rod 906 is threadedly connected to the tube pressing member 902. After detecting a metal substance, it is necessary to remove the metal substance. At this time, after determining the position of the metal, when removing the metal, it may cause pulling on the non-woven fabric. At this time, rotate the screw rod 906 to rise. Under the action of the third spring 905, the fastening tube 903 rises, so that the fastening tube 903 presses the non-woven fabric 8 tightly, and the linear motor 901 drives the tensioning tube 9 to move downward. At this time, the non-woven fabric 8 is not tensioned and is convenient for free movement. After taking out the metal, the linear motor 901 drives the tensioning tube 9 to rise, so that the non-woven fabric 8 is tensioned again, and rotate the screw rod 906 to keep a certain gap between the fastening tube 903 and the tube pressing member 902, so that the non-woven fabric 8 can move, and then the non-woven fabric 8 can be continuously detected.

[0031] In this embodiment, when detecting the non-woven fabric 8, the non-woven fabric 8 will be in a tensioned state and will cover the bearing plate 503 and apply a certain pressure to the bearing plate 503. The squeezed bearing plate 503 will contract in the direction close to the guide rod 519. The compressed bearing plate 503 will drive the pressing block 504 to move through the transmission of the connecting rod 505. Through the transmission of the pressing rod 509, the two side sealing plates 507 can be driven to approach each other, which will cause the hydraulic medium in the driving cylinder 506 to move to the inside of the actuating cylinder 510 through the pipeline 516, and then the plug 511 can be driven to move downward, and then the driving plate 515 can be driven to move downward, so that the second contact 203 contacts the first contact 202, making the coil 201 energized, and then the area of the non-woven fabric 8 can be automatically judged and the coil 201 in the corresponding area can be turned on; When the pressure-bearing plates 503 on both sides contract synchronously, the rotating rod 603 and the positioning rod 604 will move synchronously. At this time, the rotating rod 603 will not tilt. However, when the pressure-bearing plate 503 on one side does not contract, the rotating rod 603 will tilt, and the rotating rod 603 close to the side of the non-contracted pressure-bearing plate 503 will rise. When the rotating rod 603 rises, it will drive the box body 609 to rise. When the box body 609 rises, it will drive the ejector rod 607 to rise synchronously. When the non-woven fabric 8 covers the pressure-bearing plate 503, it will be limited by the ejector rod 607, making the ejector rod 607 unable to rise. At this time, the continuously rising box body 609 will compress the second spring 610 and make the third contact 611 and the fourth contact 612 contact. At this time, the electromagnet 614 generates a magnetic force to adsorb the iron block 615, thereby energizing the corresponding coil 201.

[0032] The above specific embodiments are only several alternative embodiments of the present invention.
