[0036] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 4 As shown, the present invention proposes an intelligent metal detection device for non-woven product processing, including a frame 1 and a metal detector 2 fixedly mounted on the frame 1. Multiple sets of coils 201 are fixedly mounted in the metal detector 2. The coils 201 are the main components of the metal detector 2 and directly determine the detection sensitivity, accuracy, and anti-interference ability. The coils 201 generate an alternating electromagnetic field through high-frequency alternating current, forming a dynamic magnetic field covering the detection area. This embodiment also includes a first contact 202 fixedly mounted on the coil 201, and multiple sets of second contacts 203 are slidably mounted in the metal detector 2. When the first contacts 202 and the second contacts 203 are in contact, the circuit in which the coil 201 is located is connected. When the first contacts 202 and the second contacts 203 are not in contact, the coil 201 will be disconnected, which can achieve the effect of energy saving. The circuit connection method of the coil 201 is the existing technology and will not be described in detail here.

[0038] like Figures 5 to 10 As shown, this embodiment also includes a support rod 5 installed on the frame 1, and the support rod 5 includes multiple groups of pressure sensing components corresponding to the coils 201. When the pressure sensing components are under pressure, they drive the first contact 202 and the second contact 203 to contact, and the non-woven fabric 8 will contact the support rod 5 and will support the rod 5 to apply a certain pressure. Then, the pressurized area on the support rod 5 is the area where the non-woven fabric 8 exists. It is only necessary to check this area, and the coils 201 in the remaining areas can be disconnected to achieve the purpose of energy saving.

[0039] Furthermore, the support rod 5 includes a support cylinder 501 rotatably mounted on the frame 1, the pressure sensing component includes multiple groups of first slide bars 502 slidably mounted on the support cylinder 501, a group of first slide bars 502 is fixedly mounted with a pressure plate 503, a guide rod 519 coaxially arranged with the support cylinder 501 is fixedly mounted on the frame 1, two pressure blocks 504 are slidably mounted on the guide rod 519, a connecting rod 505 is rotatably mounted between the pressure block 504 and the first slide bar 502, a driving cylinder 506 is fixedly mounted on the guide rod 519 and located between the two pressure blocks 504, when the non-woven fabric 8 is tested, the non-woven fabric 8 will It will be in a tensioned state and will cover the pressure plate 503 and apply a certain pressure to the pressure plate 503. Therefore, the pressure plate 503 in contact with the non-woven fabric 8 will be squeezed and move along the axial direction of the first slide bar 502. The squeezed pressure plate 503 will shrink in the direction close to the guide rod 519, and under the action of the connecting rod 505 and the pressure block 504, multiple pressure plates 503 will move synchronously. The non-woven fabric 8 can move smoothly on the circle formed by the pressure plates 503, and the compressed pressure plate 503 will drive the pressure block 504 to move through the transmission of the connecting rod 505.

[0040] Among them, two sealing plates 507 are slidably installed in the driving cylinder 506, and a first sealing plate 508 that can be extended and retracted along the axial direction of the driving cylinder 506 is fixedly installed between the sealing plate 507 and the driving cylinder 506. The existing seal is generally sealed by installing a sealing ring, but there will be a certain friction between the sealing ring and the driving cylinder 506, which requires the non-woven fabric 8 to apply greater pressure to the pressure plate 503, and thus it is necessary to increase the tension of the non-woven fabric 8. Excessive tension may damage the non-woven fabric. This structure can effectively reduce the occurrence of this problem. A plurality of pressure rods 509 are fixedly installed on the pressure block 504, and the pressure rods 509 are fixedly connected to the adjacent sealing plates 507. The metal detector 2 is equipped with an actuator that drives the second contact 203 to move according to the volume change between the two sealing plates 507. When the pressure block 504 moves, the sealing plates 507 on both sides can be driven closer to each other through the transmission of the pressure rod 509, thereby reducing the volume between the two sealing plates 507.

[0041] Furthermore, the execution assembly includes an execution cylinder 510 fixedly installed in the metal detector 2, a blocking block 511 is slidably installed in the execution cylinder 510, a second sealing sheet 512 is installed in the blocking block 511 and the execution cylinder 510, and the gap between the execution cylinder 510 and the blocking block 511 can be blocked, 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, a driving plate 515 is fixedly installed on the driving rod 514, the second contact 203 is fixedly connected to the driving plate 515, and the execution cylinder 510 and the driving cylinder 506 are connected by The pipe 516 is connected, and the pipe 516, the execution cylinder 510 and the driving cylinder 506 are all filled with hydraulic medium. The hydraulic medium is a liquid that cannot be compressed under the working environment. When the two sealing plates 507 are close to each other, the hydraulic medium inside the driving cylinder 506 will move to the inside of the execution cylinder 510 through the pipe 516, and then drive the block 511 to move downward, and then drive the driving plate 515 to move downward, so that the second contact 203 is in contact with the first contact 202, so that the coil 201 is 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.

[0042] It is worth noting that a plurality of slides 517 are rotatably installed on the sealing plate 507, and a second slide bar 518 is slidably installed in the slide bar 517. The second slide bar 518 is rotatably connected to the inner wall of the driving cylinder 506. Since the first sealing sheet 508 has elasticity and a certain elasticity, the first sealing sheet 508 will expand outward under the action of hydraulic pressure, thereby releasing the volume between the two sealing plates 507. Through the setting of the slide bar 517 and the second slide bar 518, the first sealing sheet 508 can be attached to the second slide bar 518 when under pressure, thereby preventing the first sealing sheet 508 from expanding outward.

[0043] like Figures 11 to 15 As shown, in this embodiment, a transition detection component 6 is installed between two adjacent groups of pressure sensing components. When the transition detection component 6 detects that the pressure sensing component is under insufficient pressure, it drives the first contact 202 to contact the second contact 203. It should be noted that the detection area of ​​one group of coils 201 is the detection area 7, and the detection areas of two adjacent groups of coils 201 partially 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 energy consumption.

[0044] refer to Figure 11 , the position distribution of the non-woven fabric 8 is as follows:

[0045] The non-woven fabric 8 completely covers the pressure plate 503;

[0046] The non-woven fabric 8 does not completely cover the entire pressure plate 503, but covers half or more of the pressure plate 503;

[0047] The non-woven fabric 8 passes over one set of pressure plates 503 and is located inside the overlap area 701 , and does not extend to the next set of pressure plates 503 ;

[0048] The non-woven fabric 8 passes over the pressure plate 503 and the overlapping area 701, and covers a small area of ​​the edge of the next group of pressure plates 503. In this case, the non-woven fabric 8 may not be able to apply sufficient pressure to the group of pressure plates 503, resulting in the group of pressure plates 503 being unable to shrink, resulting in the edge of the non-woven fabric 8 being unable to be detected, that is, the pressure sensing component is unable to withstand insufficient pressure. At this time, the transition detection component 6 actively applies a contraction force to the group of pressure plates 503.

[0049] Furthermore, the jump detection assembly 6 includes an overlap plate 601 fixedly mounted on the guide rod 519 and adjacent to the two pressure plates 503. The overlap plate 601 is located in the overlap area 701. A plurality of connecting columns 602 are slidably mounted on both ends of the pressure plate 503. A rotating rod 603 is rotatably mounted on the connecting column 602. Positioning rods 604 are slidably mounted on two adjacent rotating rods 603 located on the two pressure plates 503. The positioning rod 604 is rotatably connected to the overlap plate 601 through a connecting seat 605. Both ends of the pressure plate 503 are equipped with a lifting assembly that moves as the rotating rod 603 rises and falls. When the pressure plates 503 on both sides are synchronously contracted, the rotating rod 603 and the positioning rod 604 will move synchronously. At this time, the rotating rod 603 will not tilt. When the pressure 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 uncontracted pressure plate 503 will rise.

[0050] Among them, the jacking assembly includes a plurality of slides 606 fixedly installed at both ends of the pressure plate 503, a push rod 607 is slidably installed in the slide 606, a circular plate 608 is fixedly installed on the push rod 607, a plurality of boxes 609 corresponding to the circular plates 608 are slidably installed on the pressure plate 503, an elastic member is installed between the box 609 and the pressure plate 503, a roller 613 is rotatably installed at the bottom of the box 609, and under the action of the elastic member, the roller is always against the rotating rod 603, and then when the rotating rod 603 rises, it will drive the box 609 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, and a fourth contact 612 is fixedly installed in the box 609. There are two sealing plates 507 located in the same driving cylinder 506, one of which is fixedly mounted with an electromagnet 614, and the other is fixedly mounted with an iron block 615. 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 body 609 rises, it will drive the push rod 607 to rise synchronously. When the pressure plate 503 is covered with non-woven fabric 8, it will be limited by the push rod 607, making it impossible for the push rod 607 to rise. At this time, the box body 609 that continues to rise 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 magnetic force to adsorb the iron block 615, thereby energizing the corresponding coil 201.

[0051] like 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, and a first motor 302 is fixedly installed on the frame 1. The output shaft of the first motor 302 is coaxially fixedly connected to one of the guide tubes 3. The non-woven fabric 8 can be driven to move by the first motor 302, and the rotation speed should be kept 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 tube 3.

[0052] A support tube 4 is rotatably installed on the frame 1, and 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, and the output shaft of the second motor 402 is coaxially fixedly connected to one of the support tubes 4. The second motor can make the support tube 4 and multiple pressure plates 503 rotate synchronously to prevent relative movement between the non-woven fabric and the support tube 4 and the pressure plate 503, which may cause wear problems.

[0053] like Figures 1 to 3As shown, in this embodiment, a tensioning tube 9 is slidably and rotatably installed on the frame 1, a linear motor 901 is fixedly installed on the frame 1, the output shaft of the linear motor 901 is rotatably connected to the tensioning tube 9, a pressing tube 902 is rotatably installed on the frame 1, a fastening tube 903 is slidably installed on the frame 1, a support block 904 is fixedly installed on the frame 1, a third spring 905 is fixedly installed between the fastening tube 903 and the support block 904, and a screw 906 is threadedly connected to the pressing tube 902. After the metal material is detected, the metal material needs to be removed. At this time, after determining the metal position, when the metal is removed, it may be The non-woven fabric causes pulling, and the screw 906 is rotated to rise. Under the action of the third spring 905, the fastening tube 903 is raised, so that the fastening tube 903 presses the non-woven fabric 8, and the tensioning tube 9 is driven downward by the linear motor 901. At this time, the non-woven fabric 8 is not tensioned, which is convenient for free movement. After the metal is taken out, the tensioning tube 9 is driven to rise by the linear motor 901, so that the non-woven fabric 8 is tensioned again, and the screw 906 is rotated to maintain a certain gap between the fastening tube 903 and the pressure tube 902, so that the non-woven fabric 8 can move, and then the non-woven fabric 8 can continue to be tested.

[0054] When the non-woven fabric 8 is inspected, the non-woven fabric 8 will be in a tensioned state and will cover the pressure plate 503 and apply a certain pressure to the pressure plate 503. The squeezed pressure plate 503 will shrink in the direction close to the guide rod 519, and the compressed pressure plate 503 will drive the pressure block 504 to move through the transmission of the connecting rod 505. The transmission of the pressure rod 509 can drive the sealing plates 507 on both sides to approach each other, which will cause the hydraulic medium inside the driving cylinder 506 to move to the inside of the execution cylinder 510 through the pipeline 516, and then drive the blocking block 511 to move downward, and then drive the driving plate 515 to move downward, so that the second contact 203 contacts the first contact 202, so that the coil 201 is energized, and then the area of ​​the non-woven fabric 8 can be automatically determined and the coil 201 in the corresponding area can be turned on;

[0055] When the pressure plates 503 on both sides shrink synchronously, the rotating rod 603 and the positioning rod 604 will move synchronously. At this time, the rotating rod 603 will not tilt. When the pressure plates 503 on one side do not shrink, the rotating rod 603 will tilt, and the rotating rod 603 close to the side of the unshrinking pressure plate 503 will rise. When the rotating rod 603 rises, it will drive the box 609 to rise. When the box 609 rises, it will drive the top rod 607 to rise synchronously. When the pressure plate 503 is covered with non-woven fabric 8, it will be limited by the top rod 607, so that the top rod 607 cannot rise. At this time, the box 609 that continues to rise 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 magnetic force to adsorb the iron block 615, thereby energizing the corresponding coil 201.

[0056] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
