Abstract
The utility model relates to a kind of yarn clipping lazy-tongs of doffer, comprise installing rack, crossbeam is installed on installing rack, the two ends of crossbeam are all provided with sprocket wheel, and one of them sprocket wheel is connected with drive motors, chain is installed on sprocket wheel, several tail yarn cutting mechanisms and tail yarn fixed mechanism are installed on chain, tail yarn fixed mechanism is positioned at the place ahead of tail yarn cutting mechanism.After the cutter of the utility model after by gathering sill cuts off, tail yarn is clipped on fastening spring, can landing from spindle, tail yarn is wrapped on spindle, when empty spool inserts spindle, do not need manually tail yarn to be wound around up, while starting shooting to increase fine spining machine, the rate of letting the hair grow of yarn, reduces broken end again, save the fine spining machine start Yarn connecting working time, improved operating efficiency.
Description
Technical field
The utility model relates to a kind of yarn clipping lazy-tongs of doffer, belongs to the technical field of doffer auxiliary equipment.
Background technology
After the full yarn of spool on fine spining machine, need to take off, change empty spool and continue spinning, this process is generally manually take off and change, manual operation efficiency is extremely low, in the process of getting, need yarn to cut off, tail yarn is wrapped on spindle, empty spool is enclosed within on fine spining machine spindle and just can proceeds to be wound around.But because yarn has thin and light characteristic, operative employee easily occurs that in when operation tail yarn fails to keep being wrapped on spindle, causes start end breakage rate to increase, and has wasted the extensive work time and has removed manually to start shooting joint, has affected whole operating efficiency.
Based on this, the utility model is proposed.
Utility model content
Above-mentioned technical problem for prior art, the purpose of this utility model is to provide a kind of yarn clipping lazy-tongs of doffer, when spun yarn full spool takes off, tail yarn one end is clamped, allow the tail yarn other end be wrapped on spindle, when the past operation traveling process once of doffer, allow translational speed and the doffer gait of march of yarn clipping lazy-tongs of doffer be controlled in a rational operation interval, keep tail yarn automatic winding on spindle and do not come off, tail yarn when the improving doffer start rate of letting the hair grow, save the working time, improved operating efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of yarn clipping lazy-tongs of doffer, comprise installing rack, on described installing rack, crossbeam is installed, the two ends of described crossbeam are all provided with sprocket wheel, and one of them sprocket wheel is connected with drive motors, on described sprocket wheel, chain is installed, several tail yarn cutting mechanisms and tail yarn fixed mechanism are installed on described chain, described tail yarn fixed mechanism is positioned at the place ahead of tail yarn cutting mechanism.
Described tail yarn fixed mechanism comprises thread nipper assembly and thread nipper assembly mount pad, and described thread nipper assembly is arranged on thread nipper assembly mount pad.
Described thread nipper assembly is fastening spring or yarn gripper, and described thread nipper assembly mount pad is spring mounting seat, and described fastening spring is arranged on spring mounting seat.
Described tail yarn cutting mechanism comprises several guide pads, between described guide pad and guide pad, is provided with gathering sill, on described guide pad, cutter is installed, and the cutting edge of described cutter is positioned on gathering sill.
The beneficial effects of the utility model are as follows:
The yarn clipping lazy-tongs of the utility model doffer, be arranged on doffer, when doffer moves to a certain operating position on fine spining machine, full spool is taken out, the tail yarn exiting drops on (the at this moment clamped spring clamping of tail yarn) on fastening spring, tail yarn end is cut off (at this moment departing from full spool) by the cutter on gathering sill simultaneously, when doffer is again in operation traveling process once, the translational speed of the yarn clipping lazy-tongs of doffer and doffer gait of march are controlled in a rational operation interval, keep tail yarn automatic winding on spindle and do not come off, when empty spool inserts spindle, be clamped in the tail yarn Automatic-falling on fastening spring, empty spool is successfully inserted on the spindle that is wound around tail yarn like this, to increase the fine spining machine start rate of letting the hair grow, reduce start broken end, save the manual splice time, thereby improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;

Fig. 3 is the tail yarn cutting mechanism structural representation in the utility model;
Wherein, 1 is that installing rack, 2 is that crossbeam, 3 is that sprocket wheel, 4 is that drive motors, 5 is that chain, 6 is that fastening spring, 7 is that spring mounting seat, 8 is that guide pad, 9 is that gathering sill, 10 is that cutter, 11 is spindle.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As shown in Figure 1-Figure 3, the yarn clipping lazy-tongs of the utility model doffer, comprise installing rack 1, crossbeam 2 is installed on installing rack 1, and the two ends of crossbeam 2 are all provided with sprocket wheel 3, and one of them sprocket wheel 3 is connected with drive motors 4, during work, by drive motors 4, driven, chain 5 is installed on sprocket wheel 3, several tail yarn cutting mechanisms and tail yarn fixed mechanism are installed on chain 5, tail yarn fixed mechanism is positioned at the place ahead of tail yarn cutting mechanism.
Tail yarn fixed mechanism comprises thread nipper assembly and thread nipper assembly mount pad, and thread nipper assembly is arranged on thread nipper assembly mount pad.
Thread nipper assembly in the utility model is fastening spring 6, and thread nipper assembly can also be yarn gripper, and thread nipper assembly mount pad is spring mounting seat 7, and fastening spring 6 is arranged on spring mounting seat 7.
Tail yarn cutting mechanism in the utility model comprises several guide pads 8, between guide pad 8 and guide pad 8, is provided with gathering sill 9, and cutter 10 is installed on guide pad 8, and the cutting edge of cutter 10 is positioned on gathering sill 9.
The yarn clipping lazy-tongs of the utility model doffer; be arranged on doffer; the rotary speed of doffer movement velocity and yarn clamping mechanism remains in a rational relative velocity, and concrete mounting means is not the content that the utility model needs protection, and does not repeat herein.
The yarn clipping lazy-tongs of the utility model doffer, be arranged on doffer, the rotary speed of doffer movement velocity and yarn clamping mechanism remains in a rational relative velocity, when doffer moves to the full yarn spool on spinning machine, the spool of full yarn is taken out, the tail yarn exiting drops on fastening spring 6, by the cutter 10 on gathering sill 9, cut off, tail yarn can landing from spindle 11, tail yarn is wrapped on spindle 11, do not need manually tail yarn to be wound around up, tail yarn while the increasing start rate of letting the hair grow, reduce broken end, when empty spool inserts after spindle 11, tail yarn Automatic-falling, save the working time, improved operating efficiency.Doffer moves forward, empty spool is enclosed within on spindle 11 one by one, and drive motors 4 drive sprockets 3 rotate, and then the opposite direction motion that drives chain 5 to advance to doffer, make tail yarn thread nipper assembly and spindle keep relative static conditions, realize suitability for industrialized production.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
