Description

Technical Field

[0001] This utility model relates to the field of zipper head packaging, and more particularly to a zipper pull packaging device. Background Technology

[0002] The zipper pull consists of three main parts: the body, the ring, and the pull tab. Among these, the pull tab plays a crucial role in actual use. Users hold the pull tab to slide the zipper pull along the zipper teeth; therefore, the appearance and feel of the pull tab are essential to the overall user experience. However, during operation, friction between zipper pulls often leads to scratches and wear on the pull tab surface. This not only affects the appearance of the zipper pull but also reduces the user's tactile experience, thus negatively impacting its market sales. Therefore, the appearance and smoothness of the pull tab are of great significance for enhancing the market competitiveness of zipper pulls.

[0003] To protect zipper pulls, Chinese patent CN212354533U discloses a zipper pull film-applying packaging machine, including a frame. One end of the frame is equipped with a vibratory feeder, and below the vibratory feeder is a conveyor track for conveying zipper heads with the zipper pull facing downwards. The other end of the frame is equipped with a feeding rack for placing two rolls of single-sided adhesive film material placed opposite each other. Near the feeding rack, the frame is equipped with a guide baffle structure for guiding the movement trajectory of the single-sided adhesive film roll heads. Between the vibratory feeder and the feeding rack, the frame is equipped with a bonding station, a conveying device for conveying the zipper heads from the conveyor track to the bonding station, a pulling device for pulling the single-sided adhesive film roll heads at the guide baffle structure towards the bonding station, and cutting and pressing devices arranged opposite each other on both sides of the bonding station. After the bonding station absorbs the zipper heads, the zipper pull faces downwards. Below the bonding station is a conveyor belt device for conveying the zipper heads with the zipper pulls finished with film packaging to the outside of the frame. When using single-sided adhesive film to package pull tabs, adhesive residue is left on the pull tabs after the film is torn off. This not only reduces the user experience but also makes subsequent use difficult.

[0004] Therefore, to ensure the aesthetics and smoothness of the pulled film, a heat-shrink film is usually applied over it for protection. In the traditional production process, the pulled film is usually manually coated with the film and then manually fed into a heating mechanism for heating and shaping. This method is inefficient and labor-intensive, making it difficult to meet the needs of large-scale production. Summary of the Invention
