Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Embodiment: A nonwoven fabric intelligent detection device, such as Figure 1-Figure 8 As shown, it includes a detection body 1, and two groups of limit grooves 101 are symmetrically opened on the surface of the detection body 1, and the limit grooves 101 are L-shaped. By setting the limit grooves 101, it can play a guiding and limiting role; a vertical surface of one group of limit grooves 101 is equidistantly opened with a plurality of groups of matching teeth 102, and by setting the matching teeth 102, it can cooperate with other components to play a driving role; and an irradiation source 2 is arranged in the middle position of the detection body 1, and the interior of the irradiation source 2 has a cavity. The irradiation source 2 is a prior art, which is used to irradiate the non-woven fabric, and cooperates with the existing detection camera prior art, which is not shown in the figure, and is arranged below the non-woven fabric, and corresponds to the position of the irradiation source 2, and will move synchronously with the irradiation source 2 to ensure the detection result of the non-woven fabric; Among them, the bottom of the irradiation source 2 is symmetrically provided with an inclined groove 201, which can play a role in storage and guidance; the inner wall of the inclined groove 201 is provided with a through groove 202 connected to the cavity, which can play a role in guidance and limitation; the outer covers 3 are symmetrically installed on both sides of the detection body 1, and by setting the outer covers 3, the internal components can be protected and dust-proof; it also includes: a motor 4 is fixedly installed on one side of one group of the outer covers 3, and by setting the motor 4, a power source is provided for the irradiation source 2 to detect non-woven fabrics during movement.

[0022] Combined with Figure 1 -Attached Figure 8, and also includes a detection component 5 that can move synchronously with the non-woven fabric, so that when the non-woven fabric is detected, it can drive the irradiation source 2 to move synchronously with the non-woven fabric, detect the detection position in real time, and ensure the accuracy of the detection result; the detection component 5 includes two groups of symmetrically arranged pulley groups 501, the two groups of pulley groups 501 are arranged inside the outer cover 3, and the other ends of the pulley groups 501 are rotatably connected to the surface of the detection body 1, and the other end of one group of pulley groups 501 is coaxially connected to the output shaft of the motor 4, and by setting the pulley group 501, it can rotate under the action of the motor 4; It is worth noting that the other end of the pulley group 501 is also fixedly connected to the conveying roller installed on the detection body 1, so that when the motor 4 is in operation, it can drive the conveying roller to rotate synchronously through the pulley group 501 to convey the non-woven fabric forward; one end of the pulley group 501 is movably connected to the strip plate 502 through the connecting piece 503, and by setting the strip plate 502, it can move synchronously with the pulley group 501 and rotate; and by setting the connecting piece 503, the strip plate 502 can be intermittently connected to the pulley group 501 as needed to achieve the purpose of synchronous rotation; Among them, the connecting member 503 includes a rotating shaft 5031 inserted into the inside of the strip plate 502, and one end of the rotating shaft 5031 is rotatably connected to the surface of the detection body 1. By setting the rotating shaft 5031, the strip plate 502 can be limited, and at the same time, the strip plate 502 can be rotated with the rotating shaft 5031 as the rotation center when rotating; the surface of the rotating shaft 5031 is sleeved with a torsion spring 5032, and the two ends of the torsion spring 5032 are respectively clamped with the surfaces of the strip plate 502 and the detection body 1. By setting the torsion spring 5032, when the strip plate 502 rotates, it can be driven to deform and generate a reaction force, so that after the non-woven fabric detection is completed, the strip plate 502 can be reset by the reaction force generated by it.

[0023] Among them, a connecting rod 5033 is inserted into the rotating shaft 5031, and the connecting rod 5033 is fixedly connected to one end of the pulley group 501. By setting the connecting rod 5033, one end of the pulley group 501 can be limited, and it is ensured that when the non-woven fabric is not tested, it can rotate independently relative to the strip plate 502; the interior of the connecting rod 5033 is elastically connected to the sliding rod 5034 through a connecting spring. By setting the sliding rod 5034, the interior of the connecting rod 5033 can be retracted and the connecting spring can be stretched to generate a reaction force, so as to facilitate the subsequent resetting of the sliding rod 5034; it is worth noting that the sliding rod 5034 is initially contracted and connected to the interior of the connecting rod 5033; A metal block 5035 is fixedly installed at one end of the slide bar 5034, and an electromagnet 5036 is provided on one side of the metal block 5035, and the electromagnet 5036 is fixedly installed on the inner wall of the rotating shaft 5031; the electromagnet 5036 is electrically connected to the external power supply through a controller, and the controller is a prior art, which can intermittently turn on and off the electromagnet 5036 according to the setting of the staff, so that the electromagnet 5036 can absorb the metal block 5035 when powered on, so that the rotating shaft 5031 is slidably connected to the connecting rod 5033 through the slide bar 5034, and then driven by the pulley group 501, the strip plate 502 is driven to rotate; it is worth mentioning that when the electromagnet 5036 is powered off, the slide bar 5034 will drive the metal block 5035 to reset under the action of the connecting spring.

[0024] Among them, one end of the strip plate 502 is telescopically matched with a driven plate 504. By setting the driven plate 504, it can move synchronously with the strip plate 502 and can shrink and stretch inside the strip plate 502; the side of the driven plate 504 close to the detection body 1 is movably connected with a toothed ring 505, which is arranged inside the limit groove 101, and the toothed ring 505 is meshed with the matching tooth 102. By setting the toothed ring 505, it can move synchronously with the driven plate 504; it is worth noting that when the strip plate 502 drives the driven plate 504 to rotate, , which will drive the gear ring 505 to move synchronously inside the limiting groove 101. When the gear ring 505 starts to move downward inside the limiting groove 101, it will cooperate with the matching teeth 102 to enable the gear ring 505 to rotate; the end of the gear ring 505 is movably connected with a connecting shaft 506, and the end of the connecting shaft 506 is fixedly connected to the end of the radiation source 2. By setting the connecting shaft 506, it is possible to avoid the radiation source 2 from rotating when the gear ring 505 rotates, and at the same time, the radiation source 2 can move synchronously with the gear ring 505 when the strip plate 502 rotates.

[0025] Combined with Figure 1 -Attached Figure 8 , and also includes an adjustment component 6 for adjusting the illumination intensity of the illumination source 2, so that when the illumination source 2 moves downward, the illumination intensity of the illumination source 2 can be adjusted, so that the detection result of the detection camera is more accurate; the adjustment component 6 includes a baffle 601 and a screw rod 602. The baffle 601 is initially arranged inside the inclined groove 201 and slidably cooperates with the inner wall thereof. By setting the baffle 601, it can slide out inside the inclined groove 201 to shield the illumination source 2 with increased illumination intensity, so as to prevent the strong light from affecting the staff; Among them, a guide groove 6011 is obliquely opened on the surface of the baffle 601. By opening the guide groove 6011, it can play a role of limiting drive, so that the baffle 601 can be moved out from the inside of the inclined groove 201, so as to achieve the purpose of blocking strong light; one end of the screw rod 602 penetrates the inner wall of the cavity and the inside of the connecting shaft 506 and is fixedly connected to the end of the gear ring 505, and the other end of the screw rod 602 is rotatably connected to the inner wall of the cavity. By setting the screw rod 602, it can rotate synchronously when the gear ring 505 rotates.

[0026] The surface of the screw rod 602 is meshedly connected with a sleeve 603, and by setting the sleeve 603, it can move laterally when the screw rod 602 rotates; two groups of driven rods 604 are symmetrically installed on the surface of the sleeve 603, and the ends of the driven rods 604 penetrate through the interior of the through groove 202 and are set inside the guide groove 6011, and the driven rods 604 are slidably matched with the guide groove 6011. By setting the driven rods 604, on the one hand, it can play a limiting role to prevent the sleeve 603 from rotating synchronously with the screw rod 602, and on the other hand, it can move synchronously with the sleeve 603 and cooperate with the guide groove 6011, so that the baffle 601 can extend from the inside of the inclined groove 201 to block the strong light emitted by the irradiation source 2; the two groups of driven rods 604 A metal cylinder 605 is fixedly installed between the moving rods 604. By setting the metal cylinder 605, it can move synchronously with the sleeve 603; a conductive rod 606 is inserted into the interior of the metal cylinder 605, and the conductive rod 606 is electrically connected to the radiation source 2. By setting the lead screw 602, the function of conduction can be achieved; it is worth mentioning that the metal cylinder 605 and the conductive rod 606 form a sliding rheostat. By the metal cylinder 605 sliding on the surface of the conductive rod 606 following the sleeve 603, the resistance of the radiation source 2 is reduced, the output power is increased, the radiation intensity of the radiation source 2 can be increased, and the accuracy of the detection result can be improved. When the lead screw 602 rotates in the opposite direction, it will drive the metal cylinder 605 to rotate in the opposite direction, so that the light intensity of the radiation source 2 returns to normal.

[0027] Specifically, when the non-woven fabric is inspected, the electromagnet 5036 is powered by the controller. When the electromagnet 5036 is powered, magnetism is generated and the metal block 5035 is attracted, so that the slide bar 5034 extends from the inside of the connecting rod 5033 and stretches the connecting spring. When the metal block 5035 contacts the electromagnet 5036, the rotating pulley set 501 starts to drive the strip plate 502 to rotate, and drives the torsion spring 5032 to deform. The rotating strip plate 502 drives the driven plate 504 and the gear ring 505 to rotate synchronously, so that the gear ring 505 first descends inside the limiting groove 101, and synchronously drives the irradiation source 2 to move downward, so that the irradiation source 2 starts to approach the non-woven fabric. When the tooth ring 505 moves downward inside the limiting groove 101, the tooth ring 505 will mesh with the matching teeth 102 and rotate, so that the tooth ring 505 drives the lead screw 602 to rotate, and drives the sleeve 603 and the metal cylinder 605 to slide on the surface of the conductive rod 606, so that the resistance of the radiation source 2 becomes smaller and the output power is increased. While the metal cylinder 605 moves, the driven rod 604 will also move laterally synchronously, and through the cooperation between the driven rod 604 and the guide groove 6011, the baffle 601 begins to extend from the inside of the inclined groove 201 to block the light emitted by the radiation source 2, so that when the tooth ring 505 moves laterally along the matching teeth 102, the non-woven fabric can be detected in real time to ensure the accuracy of the detection result.
