Description

Technical Field

[0001] The utility model relates to the technical field of zipper equipment, in particular to a zipper joint detection device. Background Art

[0002] In the production process, zippers are connected to maintain the continuity of production and improve production efficiency. Figure 1 As shown, one hole 3' or two holes 3' are punched in the joint area 2' of the zipper 1' to distinguish them. In the subsequent production process of the zipper, the machine needs to accurately identify the joint area 2', skip the joint area 2' and continue production. The traditional detection method is to set a photoelectric switch to detect the punched hole 3' in the joint area 2'. The recognition accuracy is low, which will cause the machine to misjudge, causing the zipper to be directly torn or scrapped when the zipper pull head is subsequently pulled, resulting in interruption of production continuity and loss of materials, which is also a great waste when accumulated.

One lateral side of the sensing seat 5 is hinged to the hinge seat 2 through a first round pin 12, and the sensing seat 5 is distributed on the upper side of the lower guide plate 3 to realize the flipping of the sensing seat 5. A handle 14 is provided on the other horizontal side, and the longitudinal middle parts of the two sensing rods 6 are hinged to the sensing seat 5 respectively through the second round pin 13. The two sensing sheets 7 are respectively provided on the longitudinal side of the two sensing rods 6. The upper guide plate 4 is provided on the sensing seat 5 and distributed on the lower side of the sensing rod 6. The upper guide plate 4 is provided with a through groove 15 for the two sensing sheets 7 to pass through. The two springs 8 are provided between the other longitudinal side of the sensing rod 6 and the upper guide plate 4. The sensing rod 6 is swung by the spring 8, and the sensing sheet 7 passes through the through groove 15 and is embedded in the second guide groove 11. In addition, the sensing rod 6 is provided with a positioning groove 16 for the upper end of the spring 8 to be embedded. The two photoelectric switches 9 are respectively provided on the peripheral side of the sensing rod 6 away from the longitudinal side of the sensing sheet 7.
