Description

Technical Field

[0001] This utility model relates to a welding tooth welding strip machine, and more specifically to a welding tooth welding strip mechanism at both ends. Background Technology

[0002] Nylon zippers are a common type of zipper. A tooth-welding and ribbon-welding machine is an automated production line specifically designed for nylon zippers. One end of the zipper has its teeth welded, and the other end has its ribbon welded. Currently, the tooth-welding and ribbon-welding operations for nylon zippers are performed using a tooth-welding and ribbon-welding machine. For example, the applicant's utility model patent application filed in 2023, publication number CN219856083U, entitled "A Fully Automatic Lower Welding Head Tooth-Welding and Ribbon-Welding Machine," discloses a device for tooth-welding and ribbon-welding. This device provides a tooth-welding and ribbon-welding mechanism, which includes an upper mold assembly, a lower mold assembly, a hook positioning assembly, and a ribbon. The extrusion assembly enables the processing of welded teeth and welded ribs on the zipper tape. During operation, the hook positioning assembly is inserted into the node hole of the toothless section of the zipper tape, and then the zipper tape is pressed and tightened by a downward-moving pressure rod. After the rib extrusion assembly extrudes the zipper tape, the upper and lower die assemblies cooperate to form a welded rib channel and a welded tooth channel through which the zipper tape passes. This allows the ribs and teeth to be processed at the toothless end of the zipper tape. However, the above method can only process the ribs at one end of the zipper tape. When faced with zipper tapes that require rib processing at both ends, this existing welded tooth and welded rib mechanism cannot perform the processing. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a two-end welding tooth welding strip mechanism that can effectively process the welding strips at both ends of the zipper tape.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a two-end welded stripe and rib welding mechanism, comprising an upper die, a lower die, a hook positioning assembly, and a rib extrusion assembly. The rib extrusion assembly includes a power component and an extrusion head. The upper die, lower die, and extrusion head are combined to form processing channels for the welded stripe and welded teeth. When the upper die, lower die, and extrusion head are combined, a first welded stripe channel, a second welded stripe channel, and a welded tooth channel are formed. The first welded stripe channel and the second welded stripe channel are spaced apart, and the second welded stripe channel and the welded tooth channel are adjacent.

[0005] As a further improvement of this utility model, the lower end side of the upper mold is formed with a first rib section, a second rib section and a serration section. The first rib section and the second rib section are separated by an upper groove, and the second rib section and the serration section are adjacent to each other.

[0006] As a further improvement of this utility model, the upper end of the lower mold is formed with a first fusion strip, a second fusion strip, and a fusion tooth platform. The first fusion strip and the second fusion strip are separated by a lower groove, and the second fusion strip and the fusion tooth platform are adjacent. The upper groove and the lower groove are both U-shaped groove structures. When the upper mold and the lower mold are closed, the upper groove and the lower groove are spliced ​​together to form a waist-shaped hole structure for placing the pressure strip rod.

[0007] As a further improvement of this utility model, the side of the extrusion head is formed with a first rib top plate and a second rib top plate, which are respectively arranged opposite to the sides of the first rib and the second rib.

[0008] The beneficial effects of this utility model are:

[0009] Compared to the prior art mentioned in the background section, which can only process the ribs at one end of the zipper tape, the present invention's two-end rib-welding mechanism, through a uniquely designed upper die, lower die, and extrusion head combined to form a first rib channel, a second rib channel, and a rib channel, can process the ribs and ribs at both ends of the zipper tape. This effectively solves the problem that the prior art cannot process zipper tapes with ribs at both ends, and improves the processing capability and applicability of automated nylon zipper production equipment.

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1As shown, the two-end molten tooth and molten rib mechanism of the embodiment comprises an upper die 1, a lower die 2, a hook needle positioning assembly 3 and a rib extrusion assembly 4, the rib extrusion assembly 4 comprises a power component 41 and an extrusion head 42, the upper die 1, the lower die 2 and the extrusion head 42 are combined with each other to form a processing channel of the molten rib and the molten tooth. When the upper die 1, the lower die 2 and the extrusion head 42 are combined with each other, a first molten rib channel, a second molten rib channel and a molten tooth channel are formed, the first molten rib channel is spaced apart from the second molten rib channel, and the second molten rib channel and the molten tooth channel are adjacent. Compared with the molten tooth and molten rib mechanism in the background art which can only realize the rib processing of one end of the zipper tape, the mechanism can realize the rib processing of both ends of the zipper tape by using the first molten rib channel and the second molten rib channel.

[0016] Further, referring to Figure 2 As shown, the lower end side of the upper die 1 is formed with a first molten rib part 11, a second molten rib part 12 and a molten tooth part 13, the first molten rib part 11 and the second molten rib part 12 are spaced apart by an upper groove, and the second molten rib part 12 and the molten tooth part 13 are adjacent. Through the arrangement of the above structure, the upper side channel wall structure forming the first molten rib channel, the second molten rib channel and the molten tooth channel can be effectively formed.

This structure not only perfects the two-end processing function, but also optimizes the placement position of the pressing tape rod, so that the two ends of the toothless section of the zipper tape can be better processed by the molten rib.

[0018] Further, referring to Figure 4 As shown, the side part of the extrusion head 42 is formed with a first molten rib top plate 421 and a second molten rib top plate 422, the first molten rib top plate 421 and the second molten rib top plate 422 are respectively arranged opposite to the side part of the first molten rib strip 21 and the second molten rib strip 22. Through the arrangement of the first molten rib top plate 421 and the second molten rib top plate 422, the first molten rib top plate 421 and the second molten rib top plate 422 can be effectively used as the side wall of the first molten rib channel and the second molten rib channel, so that the processing of the molten rib of both ends of the zipper tape can be effectively realized. The extrusion head 42 in the embodiment is the same as the prior art, and has two front and rear parts, and the corresponding power component 41 also has two front and rear parts, which are respectively arranged on the front and rear sides of the lower die 2.

[0019] In conclusion, the two-end molten-tooth molten rib mechanism can realize the processing of the molten rib and molten tooth at the two ends of the nylon zipper belt by forming the first and second molten rib channels and the molten tooth channel through the structural design of the upper die 1, the lower die 2 and the extrusion head 42, solves the problem that the existing molten tooth molten rib mechanism in the background art can only realize the rib processing at one end of the zipper belt, and greatly improves the processing efficiency and the application range.
