Description
Technical field
The utility model belongs to Weaving device, and in particular to a kind of yarn releasing tenslator.
Background technology
Yarn releasing frame tension force takes usually using electronic control type tension force by piezoelectric ceramic as tension sensor at present
Signal control unreels motor, but piezoelectric ceramic yarn guide member is CONTACT WITH FRICTION, for a long time using can cause to yarn
Damage；Meanwhile such tension sensor can not observe directly the flexible change of yarn, thus yarn can not be observed directly
The change of tension force, it can not judge whether yarn releasing tension force is consistent and the size of tension fluctuation each one thread from beginning to end,
It can not more judge whether threads yarn releasing tension force is consistent.Broken yarn or yarn will occur when yarn releasing tension force severely subnormal
Twisting phenomenon is crimped, has a strong impact on production efficiency and the quality of production.
The content of the invention
The purpose of this utility model is to provide a kind of yarn releasing tenslator, adjusted using a kind of balance weight stepless
Mode, yarn is that one kind is in rolling contact with deflector roll and floating rolling, avoids conventional tension and controls friction to yarn.
The purpose of this utility model is achieved through the following technical solutions：
A kind of yarn releasing tenslator, including a single-ended cantilever lever fixed by rotating shaft, the free end of cantilever lever
The floating cord roller of a generation tension signal, floating cord roller connection displacement transducer are provided with, displacement transducer signal passes
It is handed to servomotor, Serve Motor Control spinning roller yarn releasing, between the rotating shaft fixing end of the cantilever lever and floating cord roller
A counterweight adjusting mechanism is provided with, wherein, the counterweight adjusting mechanism includes a slide bar, slide bar axial direction and the cantilever lever
It is arranged in an axially parallel mode, slidably balancing weight is provided with the slide bar, a transmission mechanism is connected with balancing weight, transmission mechanism
Drive the balancing weight smoothly to be moved along before and after the slide bar and then realize stepless-adjustment of the floating cord roller to yarn tension size
Section.
Scheme is further：The transmission mechanism includes the belt pulley that slide bar both ends are fixedly installed on by support, both ends
Belt pulley on be wound with belt, the balancing weight is connected on belt by fixture, and adjuster adjusts belt pulley rotating
Dynamic, belt pulley drives strap lug around pulley rotation and then drives balancing weight smoothly to be moved axially back and forth along the slide bar.
Scheme is further：The belt pulley is toothed belt wheel, and the belt is odontoid belt.
Scheme is further：The adjuster is to connect manual knob over pulleys carried.
Scheme is further：The adjuster includes a tooth form idle wheel, and tooth form idle wheel is arranged on the belt at slide bar both ends
Being engaged between wheel with odontoid belt, the left regulation wheel that a diameter is more than tooth form idle wheel is rotatablely connected by belt and tooth form idle wheel,
Adjusting knob is provided with left regulation wheel, the adjusting knob is provided with tension adjustment dial.
The beneficial effects of the utility model are：By belt drive balance weight, smooth movement realizes on a sliding bar
The electrodeless regulation of balance weight, ensure that the regulation to small Zhang Zhangli, can observe directly the change of yarn tension, and sentence
Breaking, whether yarn releasing tension force is consistent and the size of tension fluctuation each one thread from beginning to end, very easily method can sentence
Whether disconnected threads yarn releasing tension force is consistent, and broken yarn or yarn will occur when solving yarn releasing tension force severely subnormal well
Coil of wire song Twisting phenomenon.
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model transmission mechanism and balancing weight attachment structure schematic diagram.
