[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-4 As shown, this utility model provides a technical solution, an inlet mold for zipper processing, including a guide frame 1, and a clamping and leveling mechanism 2 is provided inside the guide frame 1. The clamping and leveling mechanism 2 includes a concave frame 201, a clamping roller 202, a telescopic sleeve 203, a support spring 204, an extension frame 205, an adjusting push rod 206, a lifting slider 207, and a leveling roller 208.

[0029] The top and bottom of the guide frame 1 are symmetrically connected to concave frames 201, and clamping rollers 202 are rotatably connected inside both concave frames 201. Telescopic sleeve rods 203 are equidistantly engaged at opposite ends of the two concave frames 201. Support springs 204 are engaged at the outer positions of the telescopic sleeve rods 203 between the concave frames 201 and the guide frame 1. In order to clamp the zipper and the bottom fabric, both ends of the two concave frames 201 are slidably connected to the inner wall of the guide frame 1, and the other end of the telescopic sleeve rods 203 is connected to the inner wall of the guide frame 1.

[0030] The other end of the guide frame 1 is attached to an extension frame 205. An adjustment push rod 206 is rotatably connected to the top of the extension frame 205. A lifting slider 207 is rotatably connected to the bottom of the adjustment push rod 206. A leveling roller 208 is rotatably connected between the two lifting sliders 207. In order to facilitate pushing the leveling roller 208 down, the bottom of the adjustment push rod 206 passes through the top of the extension frame 205. The outer side of the lifting slider 207 is slidably connected to the inner wall of the extension frame 205.

[0031] A tensioning and anti-deviation mechanism 3 is provided on the other side of the inner wall of the guide frame 1. The tensioning and anti-deviation mechanism 3 includes a positioning rod 301, a tensioning slider 302, a tensioning spring 303, a pad 304, a tensioning roller 305, and an anti-deviation ring 306.

[0032] Positioning rods 301 are symmetrically engaged on the other side of the guide frame 1. Tensioning sliders 302 are movably sleeved on the outer sides of both positioning rods 301. Tensioning springs 303 are engaged on the outer sides of the positioning rods 301 and the guide frame 1 respectively. A pad 304 is engaged on the adjacent end of each of the two tensioning sliders 302. A tensioning roller 305 is rotatably connected between the two pads 304. In order to tighten the zipper and the bottom fabric, one end of the tensioning slider 302 is slidably connected to the inner wall of the guide frame 1. The outer diameter of the pad 304 is larger than the outer diameter of the tensioning roller 305. Anti-deviation rings 306 are symmetrically sleeved on the outer side of the tensioning roller 305 through threads. In order to facilitate the limiting of the zipper and the bottom fabric, a rotating ring is engaged on the opposite end of each of the two anti-deviation rings 306. The inner diameter of the rotating ring is larger than the inner diameter of the anti-deviation ring 306.

[0033] The working principle and usage process of this utility model are as follows: First, the zipper and the base fabric are placed overlapping between two clamping rollers 202. Then, the extension and retraction characteristics of the support spring 204 are used to push the concave frame 201 and the clamping rollers 202 to move relative to each other, thereby clamping and fixing the zipper and the base fabric to ensure the fit between the zipper and the base fabric. At the same time, because of the clamping rollers 202, it is convenient for people to push the zipper and the base fabric to move in the future, so as to continuously clamp and fit the zipper and the base fabric, thus improving convenience.

[0034] Next, the fitted zipper and base fabric are passed over the tensioning roller 305. Then, due to the contraction of the tension spring 303, the tensioning slider 302, the pad 304 and the tensioning roller 305 slide and rise along the positioning rod 301 to tighten and transport the zipper and base fabric, prevent wrinkles, and facilitate subsequent sewing. In addition, rotating the anti-deviation ring 306 changes the distance between the two anti-deviation rings 306, which helps to limit the zipper and base fabric, prevent deviation, and ensure alignment and fit.

[0035] Finally, rotating the adjusting push rod 206 pushes the lifting slider 207 and the leveling roller 208 down, thereby pressing down and flattening the bonded zipper and base fabric, further preventing wrinkles.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
