Abstract
The utility model discloses a tightness regulating device of a zipper, which is characterized in that a swing rod and swing rod mounting frames are arranged, wherein the middle part of the swing rod is hinged on the swing rod mounting frames, two ends of the swing rod are respectively fixed with a rotating shaft, an idler wheel is arranged on the rotating shaft, and the rotating shaft is vertical to the travelling direction of the zipper; a tension spring is respectively arranged at two ends of the swing rod and between the swing rod mounting frames, and an inclined angle is formed between the swing rod and the plane. The zipper passes through between two idler wheels and is respectively contacted with an upper edge part of one idler wheel and a lower edge part of the other idler wheel so as to form a Z-shaped travelling route. When the travelling zipper is too loose, the inclined angle between the swing rod and the plane is enlarged so as to cause the zipper to become tensional; and when the travelling zipper is too tight, the angle between the swing rod and the plane is reduced so as to cause the zipper to become loose. The utility model can automatically regulate the tension degree of the zipper and ensure the quality of the zipper to be more stable during the injection molding.
Description
Technical field
The utility model relates to a kind of adjusting device, particularly a kind of slide fastener rate of tension adjusting device.
Background technology
The characteristic of slide fastener is with simple pulling action, just the opening both sides of clothes or knapsack etc. can be done simple and rapid combination and is separated, and therefore is used widely.Existing slide fastener generally has metal zip fastener, delrin zippers with pulllers and nylon zipper etc., and it mainly cooperates a pull head to be made up of a left side moulding strand with the right moulding strand.The end that slide fastener closes up is provided with down and ends, and the terminal left and right sides strand of bifurcated respectively is provided with on one and ends.The injection moulding of injection moulding machine of passing through that ends is up and down finished.The closed-end zipper semi-finished product are bar-shape, and the front-end and back-end of injection moulding machine lower bolster are respectively equipped with slide fastener feed well and slide fastener blow tank.Slide fastener blow tank position is provided with driving wheel, and slide fastener enters injection mold from the slide fastener feed well under the effect that drags of driving wheel, shifts out from the slide fastener blow tank after injection moulding finishes.Existing injection moulding machine lacks slide fastener degree of tightness governor motion, when causing slide fastener on chain groove, to be advanced, the time pine when tight, the injection mo(u)lding of the slide fastener that is unfavorable for.
The utility model content
The purpose of this utility model is to overcome the prior art defective, and a kind of slide fastener slack adjuster that can regulate slide fastener elasticity when chain groove is advanced is provided.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of slide fastener slack adjuster, it is characterized in that: include fork, fork installing rack, the middle part of fork is hinged on the fork installing rack, the two ends of fork respectively are provided with and are fixed with a rotating shaft, and rotating shaft is provided with roller, and the direct of travel of rotating shaft and slide fastener is perpendicular, respectively be provided with an extension spring between the two ends of fork and the fork installing rack, fork becomes an inclination angle with horizontal plane.
The beneficial effects of the utility model are: slide fastener passes between two rollers, and slide fastener contacts with the upper edge portion of a roller respectively and contacts with the lower edge portion of another roller, forms the course of one " Z " font.When the slide fastener of advancing was too lax, the angle of inclination increasing that fork is become with horizontal plane made the slide fastener tensioning that becomes; When the slide fastener of advancing was too tightened, slide fastener reduced fork and horizontal angulation, makes slide fastener become lax.The utility model can be regulated the rate of tension of slide fastener automatically, and quality is more stable when making the slide fastener injection moulding.
Below in conjunction with accompanying drawing the utility model is described in further detail
Description of drawings
Fig. 1 is the utility model schematic perspective view;
Fig. 2 is the utility model front view;
The specific embodiment
To shown in Figure 2, a kind of slide fastener slack adjuster includes fork 4, fork installing rack 7 as Fig. 1.The middle part of fork 4 is hinged on the fork installing rack 7, and the two ends of fork 4 respectively are provided with and are fixed with a rotating shaft, and rotating shaft is provided with roller 3,5, and the direct of travel of rotating shaft and slide fastener 2 is perpendicular.Respectively be provided with an extension spring 6,8 between the two ends of fork 4 and the fork installing rack 7, since about the length of two extension springs 6,8 inconsistent, the length of right side extension spring 8 is greater than the length of left side extension spring 6, during fork 4 normalities, become an inclination angle with horizontal plane, the inclination angle that is become is generally between 15 °～30 °.
Slide fastener 2 passes between two rollers, and slide fastener 2 contacts with the upper edge portion of a roller 3 respectively and contacts with the lower edge portion of another roller 5, forms the course of one " Z " font.When the slide fastener 2 of advancing was too lax, the angle of inclination increasing that fork 4 is become with horizontal plane made slide fastener 2 tensioning that becomes; When the slide fastener 2 of advancing was too tightened, slide fastener 2 reduced fork 4 and horizontal angulation, makes slide fastener 2 become lax.The utility model can automatic zipper 2 rate of tension, quality is more stable when making slide fastener 2 injection mouldings.
Claims (2)
