[0002] Zippers can be divided into three main categories based on their materials: metal zippers, resin zippers, and nylon zippers. Metal zipper teeth are made by using copper or aluminum wire through a tooth-laying machine, resin zipper teeth are made by using polyester plastic pellets colored with dyes and then through an injection molding machine, while nylon zipper teeth are made by using nylon monofilaments heated and wound around a central wire through a screw-driven mold. Compared to metal and resin zippers, nylon zippers are more cost-effective, have higher production volume, and are more widely used.

[0003] The existing nylon zipper forming machines are difficult to assemble, have low assembly precision, and are difficult to calibrate, resulting in inconsistent quality of the nylon zippers produced and making it difficult to guarantee the quality of the zippers. Summary of the Invention

[0037] refer to Figure 1-7 This utility model proposes a zipper forming machine, which includes a frame 1 and a main box 2 disposed on the frame 1. The main box 2 is provided with a front bullhead assembly 3, a rear bullhead assembly 4, a mold 5, a front monofilament rotating frame 6, a rear monofilament rotating frame 7 and a monofilament protection component 8. The main box 2 is provided with a shell 9 on the outside.

[0038] The main housing 2 is integrally cast from a rigid material. The main housing 2 includes a body 21, which includes a mold mounting surface 22 and a front bullhead mounting base 23. The front bullhead mounting base 23 is located on one side of the mold mounting surface 22. The mold mounting surface 22 extends on a first plane. The front bullhead mounting base 23 includes a mounting base body 231 with mounting holes 232. The front bullhead assembly 3 is mounted on the mounting base body 231 through the mounting holes 232. The axis of the mounting holes 232 extends on a second plane, and the first and second planes are parallel. The integral casting of the main housing 2 effectively controls and ensures the parallelism of the first and second planes. During installation, no recalibration is required to ensure the perpendicularity of the mold mounting surface 22 and the front bullhead assembly 3. This effectively ensures that the deviation between the monofilament from the mold 5 and the front bullhead assembly 3 is within a preset range, preventing damage to the monofilament due to this deviation.

[0039] In this embodiment, the mounting base body 231 is arranged perpendicular to the first plane, and the axis of the mounting hole 232 is arranged parallel to the first plane.

[0040] In this embodiment, a raised protrusion 24 is provided on one side of the body 21, and the mold mounting surface 22 is provided at the end of the raised protrusion 24 away from the body 21. The height of the raised protrusion 24 corresponds to the front toggle head mounting seat 23, so that the position of the front bullhead assembly 3 matches that of the mold 5.

[0041] In this embodiment, the front bullhead mounting base 23 further includes a connecting part 233 connected to the mounting base body 231. The connecting part 233 connects the mounting base body 231 to the body 21. The connecting part 233 includes an arc-shaped transition surface 2331. The arc-shaped transition surface 2331 can ensure the rigidity of the connection structure and reduce the vibration of the main housing 2 during operation.

[0042] In another embodiment, the main body 21 is provided with multiple hollow structures, which can effectively reduce the weight of the main box 2.

[0043] In the above embodiment, the mold 5 is connected to the body 21. The mold 5 is provided with a first mating surface corresponding to the mold mounting surface 22, which facilitates the control of the extension direction of the mold 5. The front bullhead assembly 3 is installed on the front bullhead mounting base 23. The front bullhead assembly 3 includes a first mating part corresponding to the mounting hole 231, so that it can be directly inserted into the mounting hole 231, which is convenient for installation and can ensure the position and angle after installation, thereby ensuring the perpendicularity of the mold 5 and the front bullhead assembly 3, and thus ensuring the quality of the monofilament.

[0044] In the above embodiment, the main housing 2 is further provided with a monofilament protection component 8 to restrict the movement of the monofilament within the main housing 2 and prevent damage to the monofilament due to excessive swinging. The monofilament protection component 8 comprises a monofilament guard ring 81, a guard ring mounting plate 82, a guide rail 83, an auxiliary component 84, a rolling component 85, and a limiting baffle 86. The track 83 is disposed on the main body 21 and extends from one end near the front head group 3 to the other end near the rear head group 4. The monofilament guard ring 81 is slidably connected to the guide rail 83 through the guard ring mounting plate 82. The monofilament guard ring 81 slides between the front head group 3 and the rear head group 4, facilitating operation by placing it in different positions when changing materials and working states. In this embodiment, the guide rail 83 is rod-shaped, and the guard ring mounting plate 82 has a hole corresponding to the guide rail 83. The guide rail 83 passes through the hole, so that the guard ring mounting plate 82 can slide along the guide rail 83. The auxiliary component 84 is located on one side of the guide rail 83 and connected to the main body 21. It extends from one end near the front bullhead assembly 3 to the end near the rear bullhead assembly 4 and is parallel to the guide rail 83. A connecting portion is provided on one side of the retaining ring mounting plate 82. This connecting portion is connected to the rolling element 85, which is in a rolling connection with the auxiliary component 84, thereby ensuring the stability of the sliding of the monofilament retaining ring 8. In this embodiment, the rolling element 85 consists of two opposing rollers, each located on one side of the auxiliary component 84, thus sandwiching the auxiliary component 84 in the middle and ensuring connection stability. The limiting baffle 86 is located on the side of the monofilament retaining ring 81 near the front bullhead assembly 3 or the rear bullhead assembly 4, and is used to limit the displacement of the monofilament retaining ring 81. The monofilament guard ring 81 can slide back and forth in the direction from the front bullhead group 3 to the rear bullhead group 4, so that it can automatically move and adapt according to the rotation and movement of the monofilament, thereby effectively limiting the movement of the monofilament and avoiding damage to the monofilament caused by radial expansion during movement and rotation.

[0045] In another embodiment of this utility model, the auxiliary component 84 is further provided with a magnetic attracting component 87, and the retaining ring mounting plate 82 is provided with a magnetic attracting part corresponding to the magnetic attracting component 87. When the retaining ring mounting plate 82 passes through the position corresponding to the magnetic attracting component 87, the magnetic attracting component 87 and the magnetic attracting part attract each other, thereby controlling the displacement of the monofilament retaining ring 82. In this embodiment, the retaining ring mounting plate 82 can be made entirely of magnetic material, or only the part corresponding to the magnetic attracting component 87 can be made of magnetic material, and the part corresponding to the magnetic attracting component 87 is the magnetic attracting part.

[0046] In another embodiment of this utility model, the auxiliary component 84 is a sliding rod, and the protective ring mounting plate 82 is provided with a sliding component corresponding to the sliding rod.

[0047] In another embodiment of the present invention, the auxiliary component 84 is a sliding groove, and the protective ring mounting plate 82 is provided with a sliding component corresponding to the sliding groove.

[0048] In the above embodiments, the monofilament retaining ring 81 is formed by spirally winding multiple strands of rope in a preset direction. The preset direction is opposite to the direction of rotation of the monofilament, so that the monofilament and the monofilament retaining ring 81 only make point contact. That is, during the movement of the monofilament, assuming that the current point of contact with the monofilament retaining ring 81 is the first point, the first point will not contact the monofilament retaining ring 81 when the monofilament continues to move. The point of contact with the monofilament retaining ring 81 at the next instant is the second point. That is, each point only contacts the monofilament retaining ring 81 once and will not contact it a second time. This setting can effectively avoid the situation where a certain part of the monofilament contacts the monofilament retaining ring multiple times during the molding process, which would cause damage to the monofilament and effectively ensure the surface quality of the monofilament.

[0049] In this embodiment, the monofilament guard ring 81 is formed by winding multiple strands of steel wire rope. The multiple strands of steel wire rope are connected by staggered welding and the surface is polished to effectively ensure that the monofilament is not scratched by the monofilament guard ring.

[0050] In the above embodiment, the center distance between two adjacent "threads" of each wire rope is more than 3 times the diameter of the single wire. This setting can effectively ensure the positional difference between the high and low points of each wire rope, effectively ensure the point contact between the single wire and the single wire guard ring 81, and avoid damage to the single wire. The above "thread pitch" is selected as 3-6 times, which can not only ensure the positional difference between the high and low points, but also facilitate the processing and structural stability of the single wire guard ring.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
