Abstract
The utility model provides a yarn taking-up mechanism for a machine modified for knitting, comprising a machine base, a yarn taking-up spring and a limiting hook. One end of the yarn taking-up spring and one end of the limiting hook are all connected with a machine base, and the connecting points thereof keep a certain distance. The other end of the yarn taking-up spring threads the inside part of a bended hook on the other end of the limiting hook. The yarn taking-up spring is connected with a machine base through a regulating mechanism with a rotatable angle. Under the action of the elasticity of the spring of the adjusting knob of the utility model, the positioning tooth of the adjusting knob and the positioning tooth of a fixing screw are mutually adjacent to have a positioning function. Every time, the relative positioning tooth misses one or a plurality of tooth positions as a result of rotating the adjusting knob, and the adjusting knob can stop on the position after the regulation because of the positioning function. The adjusting knob drive one end of the yarn taking-up spring rotate together to achieve the purpose of regulating the tightness of the yarn taking-up spring. The yarn taking-up mechanism for a machine modified for knitting is very convenient and easy to regulate to the suitable elasticity, so the machine modified for knitting can work in the best status.

Background technology
Sewing machine is in when work, and suture passes the pin hole of suture needle, and the reciprocating motion by suture needle drives suture and passes the stitching that clothing is realized clothing repeatedly.In order to make suture needle in the process that comes and goes, make suture keep certain rate of tension, avoid random line or broken string, generally on sewing machine, be provided with the take-up structure.Existing take-up structure comprises support, thread take-up spring, spacing colluding, thread take-up spring all is connected with support with a spacing end that colludes, its tie point is at a distance of certain distance, the other end of thread take-up spring passes in the spacing hook that colludes the other end, and being provided with thimble at this end, suture is guided suture needle into after passing this thimble again.Its shortcoming is that thread take-up spring is fixedlyed connected with the support position, and its elastic force is the location decision when connecting fully, if elastic force is improper, then will unclamp the fixed angle of regulating spring again again, unusual trouble, and be difficult for being adjusted to suitable degree.
Summary of the invention
The purpose of this utility model just provides a kind of sewing machine thread take-up mechanism that can regulate the thread take-up spring tightness, to solve the difficult problem of regulating of thread take-up spring elasticity that existing thread take-up mechanism exists.
The technical solution of the utility model is: comprise support, thread take-up spring, spacing colluding, thread take-up spring all is connected with support with a spacing end that colludes, its tie point is at a distance of certain distance, the other end of thread take-up spring passes in the spacing hook that colludes the other end, described thread take-up spring by one can rotational angle governor motion be connected with support.
Described governor motion comprises adjusting knob, hold-down screw, adjusting knob spring, take-up torsion spring, adjusting knob one end is provided with footpath outward flange and axle certre hole, the aperture of the axle certre hole in outward flange is greater than other position, be provided with positioning tooth at the end face of this big footpath step along circumference, described hold-down screw passes from the bigger diameter end of adjusting knob and is connected on the described support, its nut is embedded in the hole, big footpath of described adjusting knob, is provided with the positioning tooth that cooperates with the location flank of tooth of described adjusting knob in the nut inboard; Other end inside at described adjusting knob is provided with the adjusting knob spring, and the two ends of this adjusting knob spring withstand on a side and the support surface of the inward flange of adjusting knob axle certre hole respectively; The take-up torsion spring be helical form and be enclosed within adjusting knob outside, the one end is connected with an end of described thread take-up spring, the other end is connected with the inner face of the outward flange of adjusting knob.
The outside at the outward flange of described adjusting knob is provided with anti-skidding line.
Adjusting knob of the present utility model is under the elastic force effect of its spring, make between the positioning tooth of adjusting knob positioning tooth and hold-down screw mutually near and play a part to locate, after the moving adjusting knob of revolution makes the relative positioning tooth miss one or more teeth position, because above-mentioned positioning action, adjusting knob will be parked in the position after the adjusting, and an end of adjusting knob drive take-up torsion spring together rotates, and reaches the purpose of regulating the thread take-up spring degree of tightness.Not only regulate very conveniently, and be easy to be adjusted to suitable elastic force, make sewing machine be operated in optimum state.

The specific embodiment
Referring to Fig. 1～Fig. 6, the utility model comprises support 1, thread take-up spring 4, spacingly colludes 5 and governor motion, thread take-up spring 4 by one can rotational angle governor motion be connected with support.Spacing 5 the end of colluding directly is connected with support 1.Thread take-up spring 4 and spacing collude 5 with the tie point of support 1 at a distance of certain distance, the other end of thread take-up spring 4 is provided with thimble 41 and passes in the spacing hook that colludes 5 other ends.
Described governor motion comprises adjusting knob 2, hold-down screw 3, adjusting knob spring 6, take-up torsion spring 42.Adjusting knob 2 one ends are provided with footpath outward flange and axle certre hole, and the aperture of the axle certre hole in outward flange is greater than other position, are provided with positioning tooth 22 along circumference at the end face of this big footpath step, are provided with inward flange 23 at the axle certre hole place adjacent with positioning tooth 22.Described hold-down screw 3 passes from the bigger diameter end of adjusting knob 2 and is connected on the described support 1, and its nut is embedded in the hole, big footpath of described adjusting knob 2, is provided with the positioning tooth 31 that cooperates with the positioning tooth 22 of described adjusting knob 2 in the nut inboard.Other end inside at described adjusting knob 2 is provided with adjusting knob spring 6, and the two ends of this adjusting knob spring 6 withstand on a side and support 1 surface of the inward flange 23 of adjusting knob axle certre hole respectively, produces to make the elastic force of adjusting knob 2 near the hold-down screw cap.Take-up torsion spring 42 is a helical form, is enclosed within outside the adjusting knob 2, and the one end is connected with an end of described thread take-up spring 4, and the other end has an axially straight end 43 to insert in the aperture 21 of outward flange of adjusting knobs 2, realizes and being connected of adjusting knob 2.Support 1 is connected on the frame of sewing machine by fixing hole 11, and fastening by trip bolt 12.
