[0019] A circular groove 10 is provided at one end of the I-shaped cylinder 6, and a rack 11 is provided on the inner wall of the circular groove 10. A first bracket 12 is fixedly installed on the surface of the equipment housing 1 and on one side of the circular groove 10. A first gear 13 is installed on the end of the first bracket 12 through a rotating shaft. The other end of the first gear 13 is located in the circular groove 10, and the first gear 13 is meshed with the rack 11. A through groove is provided on the surface of the equipment housing 1 and between the I-shaped cylinder 6 and the first bracket 12. A second gear 14 is rotatably installed inside the through groove, and the second gear 14 is meshed with the first gear 13. A support plate is installed at one end of the interior of the equipment housing 1, and a stepping motor 16 is installed above the support plate. The output end of the stepping motor 16 is fixedly connected to a light Rod 17, a third gear 15 is installed on the surface of the light rod 17, the third gear 15 is meshed with the second gear 14, the stepper motor 16 drives the light rod 17 to rotate, and the third gear 15 on the surface of the light rod 17 will also rotate, through the meshing of the rack 11 and the first gear 13, and the linkage of the first gear 13 with the second gear 14 and the third gear 15, accurate transmission control is achieved, the drive of the stepper motor 16 can accurately transmit the motion to the I-shaped cylinder 6 through the gear set, ensuring the stability and accuracy of the equipment operation, and the forward or reverse rotation of the I-shaped cylinder 6 can realize the winding or releasing of the zipper, so that the device can detect the overall zipper and ensure the comprehensiveness of the detection result.

[0020] A groove 7 is provided at the middle end of the I-shaped tube 6, and a rubber pull strip 8 is fixedly installed on the inner wall of the groove 7. Since there is a certain distance between the I-shaped tube 6 and the detection element, when the zipper is released from the surface of the I-shaped tube 6, the rubber pull strip 8 can increase the stroke of the zipper to ensure that the zipper can completely contact the detection element, and the device can detect the entire zipper. An arc block 9 is installed at the end of the rubber pull strip 8, and the other end of the arc block 9 is connected to a positioning slot. The positioning slot can clamp and fix one end of the zipper, and the end of the zipper can be fixedly connected to the rubber pull strip 8.

[0021] A flat plate is fixedly installed inside the device housing 1 and below the support plate. A reciprocating mechanism 4 is installed inside the device housing 1. The reciprocating mechanism 4 includes a disc, which is fixedly installed on the surface of the light rod 17 and is located on one side of the third gear 15. Four arc-shaped triangular blocks 18 are evenly arranged on the surface of the disc. A sliding cylinder 19 is movably arranged directly below the disc. A connecting column 20 is fixedly installed at the bottom of the sliding cylinder 19. The connecting column 20 movably passes through the flat plate. A first spring 21 is installed on the surface of the connecting column 20 and between the sliding cylinder 19 and the flat plate. A square bar 22 is fixedly connected to the bottom end of the connecting column 20. A path groove is opened on the surface of the device housing 1. The surface of the square bar 22 is movably installed in the path groove. The trajectory of the reciprocating motion is ensured to be precisely controllable, and deviation or jamming during the motion is avoided. A positioning slot is installed at the end of the square bar 22 away from the connecting column 20. When the light rod 17 rotates, the disc will also rotate synchronously. At this time, the four arc-shaped triangular blocks 18 have a certain squeezing effect on the sliding cylinder 19, and under the action of the first spring 21, the sliding cylinder 19 will always be in contact with the four arc-shaped triangular blocks 18. Through the design of the arc-shaped triangular blocks 18, the rotational motion of the light rod 17 is converted into the up and down reciprocating motion of the sliding cylinder 19. The motion process is smooth and regular, ensuring the stability and reliability of the equipment operation. When the connecting column 20 reciprocates up and down, the square bar 22 will be synchronously displaced in the path groove.

[0022] A first guide column 24 is fixedly installed above the plate, and a guide column 23 is installed at the end of the sliding cylinder 19. The guide cylinder 23 is movably installed on the surface of the first guide column 24 to ensure the stability of the sliding cylinder 19 and the connecting column 20 during movement, further enhancing its stability and reliability.

[0023] A positioning slot is provided at the top of the pull strip 27, a slide slot 28 is provided on the surface of the device housing 1 and just below the path slot, a protrusion is provided on the surface of the pull block 25 which is slidably installed in the slide slot 28, when the I-shaped tube 6 reels the zipper, the pull block 25 is pulled upward by its pulling force, and with the cooperation of the protrusion and the slide slot 28, the stability of the pull block 25 during movement can be ensured, thereby improving the operation efficiency of the device, a steel rope 29 is connected to the bottom of the pull block 25, a collecting slot is provided at the bottom end of the inside of the device housing 1, and a second guide column 31 is fixedly installed inside the collecting slot, and the second guide column 31 A sliding block 30 is slidably installed on the surface, a second spring 32 is provided on the surface of the second guide column 31, and the end of the second spring 32 is connected to the sliding block 30. The steel rope 29 movably passes through the device housing 1 and is connected to the sliding block 30. When the I-shaped cylinder 6 reels the zipper, the sliding block 30 moves to the front of the device housing 1, the second spring 32 contracts, and the pulling block 25 is gradually lifted upward under the action of the tension. When the I-shaped cylinder 6 releases the zipper, the elastic force of the second spring 32 pushes the sliding block 30 to the rear of the device housing 1, and the pulling block 25 returns to the bottom of the device housing 1.

[0024] A rectangular block 33 is provided on the surface of the device housing 1 and above the path groove. Side ears 34 are fixedly installed at both ends of the rectangular block 33. The side ears 34 are fixedly installed on the surface of the device housing 1 by bolts. Under the action of the bolts, the rectangular block 33 can be fixed on the surface of the device housing 1. A through hole 35 is penetrated in the middle of the rectangular block 33, and the zipper can pass through the through hole 35. The through hole 35 serves as a limit for the zipper, thereby ensuring the stability of the zipper when being detected.

[0025] The positioning card slot is a rectangular slot with a threaded hole on the top of the rectangular slot. A threaded column is installed with the internal thread of the threaded hole. A pressing piece is provided at one end of the threaded column in the rectangular slot, and a rotating block is provided at the other end of the threaded column. The cooperation between the threaded hole and the threaded column makes the installation process simple and easy. You only need to put the zipper into the rectangular slot and then rotate the threaded column to complete the fixing or adjustment of the zipper by the pressing piece, which can effectively fix the zipper and prevent it from loosening or shifting.

[0026] Working principle: First, the staff passes the zipper surface through the through hole 35, and then fixes the top of the zipper in the positioning slot at the end of the arc block 9, and then matches the zipper pull head with the positioning slot at the end of the square strip 22. At this time, since the pull head is in the middle of the zipper, the bottom of the zipper is in a separated state. Finally, the two ends below the zipper are respectively matched with the positioning slots at the top of the two pull strips 27 to complete the installation of the zipper. Then the stepper motor 16 drives the light rod 17 to rotate, and the third gear 15 on the surface of the light rod 17 will also rotate. Through the meshing of the rack 11 and the first gear 13, and the linkage of the first gear 13 with the second gear 14 and the third gear 15, the drive of the stepper motor 16 can accurately transmit the motion to the I-shaped cylinder 6 through the gear set. Through the forward or reverse rotation of the I-shaped cylinder 6, the zipper can be wound or released. At the same time, the disc will also rotate synchronously. At this time, the four arc-shaped triangular blocks 18 have a certain squeeze on the sliding cylinder 19 The sliding cylinder 19 is under pressure, and under the action of the first spring 21, the sliding cylinder 19 will always be in contact with the four arc-shaped triangular blocks 18. Through the design of the arc-shaped triangular blocks 18, the rotational movement of the light rod 17 is converted into the up and down reciprocating movement of the sliding cylinder 19, and the square bar 22 will be synchronously displaced in the path groove. When the I-shaped cylinder 6 reels the zipper, the sliding block 30 will move toward the front of the device housing 1, and the second spring 32 will contract. The pulling block 25 will gradually lift up under the action of the tension. When the I-shaped cylinder 6 releases the zipper, the elastic force of the second spring 32 will push the sliding block 30 to the rear of the device housing 1. At this time, the pulling block 25 will return to the bottom of the device housing 1. This structure can always ensure that the zipper is in a straight state, which is convenient for the detection of the zipper. When the zipper moves upward or downward as a whole, the pull head will repeatedly move up and down on the zipper surface, which can cover the entire zipper, ensure the comprehensiveness of the detection result, and ensure the accuracy and reliability of the detection result.
