Abstract

The utility model relates to a yarn loosening and let-off mechanism, and in particular relates to an electric yarn loosening and let-off mechanism. The electric yarn loosening and let-off mechanism comprises a warp beam driven by a warp beam gear, a tension shaft used for controlling the rotating speed of the warp beam and a switch, wherein the warp beam is provided with a carrier gear which is meshed with the warp beam gear. The electric yarn loosening and let-off mechanism is characterized in that the warp beam is also provided with a clutch and an electric device; and the electric device comprises a motor, a driven belt wheel, a belt connecting the motor with the driven belt wheel, a speed reducer arranged at one side of the driven belt wheel and a main gear meshed with the carrier gear. The yarn loosening and let-off mechanism disclosed by the utility model is reasonable in structural design, influence of noise is reduced, machine speed can be high, and mechanism stability is also greatly enhanced.

Description

A kind of electronic loose yarn warp-feeding mechanism
Technical field
The utility model relates to a kind of loose yarn warp-feeding mechanism, relates in particular to a kind of electronic loose yarn warp-feeding mechanism.
Background technology
Warp-feeding mechanism of the prior art mainly is mechanical warp-feeding mechanism, and it mainly is made up of cam mechanism and ratchet mechanism and carrier gear mechanism driving, and the transmission of power of cam rotation is given through axle, makes through axle and rotates.Though ratchet mechanism is simple in structure, easy to manufacture, reliable motion, and the corner of ratchet scalable in a big way, there are bigger impact and noise, kinematic accuracy not high during work, so machine speed is difficult to raising, stability is also very poor.
The utility model content
The purpose of the utility model is in order to overcome above-mentioned technical problem, a kind of electronic loose yarn warp-feeding mechanism to be provided, reduced The noise greatly, and machine speed also can be very high, and mechanism stable property has also strengthened greatly.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
A kind of electronic loose yarn warp-feeding mechanism; It comprises by the warp axle that drives through shaft gear, is used to control said tension axis and switch through the axle rotating speed; Be provided with and the said carrier gear that is meshed through shaft gear on axle said; It is characterized in that, on axle, also be provided with clutch and electric device said, said electric device comprise motor, driven pulley, connection motor and driven pulley belt, be located at the decelerator of driven pulley one side and the master gear that is meshed with said carrier gear.
Further, said clutch is an electromagnetic clutch, is located at a side of described belt, is used to control the clutch time of motor.
The beneficial effect of the utility model is: the electronic loose yarn warp-feeding mechanism of the utility model, abolished cam of the prior art and ratchet mechanism, and directly drive after slowing down through decelerator by motor and rotate through axle.The motion because loose yarn run duration is had a rest, so between motor and decelerator, installed electromagnetic clutch additional, electromagnetic clutch is not worked during the not warp let-off, motor idle running.The utility model has not only reduced noise greatly, and machine speed also can be very high, and mechanism stable property has also strengthened greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to shown in Figure 1; It comprises by the warp axle 9 that drives through shaft gear 8, is used to control said tension axis 10 and switch 11 through axle 9 rotating speeds; Be provided with and the said carrier gear 7 that is meshed through shaft gear 8 on axle 9 said; Also be provided with clutch and electric device through axle on 9 said, said electric device comprises motor 1, driven pulley 3, connect motor 1 and driven pulley 3 belt 2, be located at the decelerator 4 of driven pulley 3 one sides and the master gear 6 that is meshed with said carrier gear 7, said clutch is an electromagnetic clutch 5; Be located at a side of described belt 2, be used to control the clutch time of motor 1.
Continue with reference to shown in Figure 1; During operate as normal; Motor 1 electric back is passed to driven pulley 3 through belt 2 and is driven decelerators 4 work, drive carrier gears 7 through master gear 6 again and pass to power through shaft gear 8, drives again through shaft gear 8 and makes discontinuity through axle 9 and move; Control the clutch time of motor 1 clutch then through tension axis 10 by-pass cockes 11, to limit through axle 9 motion reach that the warp let-off measures as required what to evenly loosening warp thread through axle 9.
More than show and described basic principle, principal character and the advantage of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain by appending claims and equivalent circle thereof.

Claims (2)

1. electronic loose yarn warp-feeding mechanism; It comprises by the warp axle that drives through shaft gear, is used to control said tension axis and switch through the axle rotating speed; Be provided with and the said carrier gear that is meshed through shaft gear on axle said; It is characterized in that, on axle, also be provided with clutch and electric device said, said electric device comprise motor, driven pulley, connection motor and driven pulley belt, be located at the decelerator of driven pulley one side and the master gear that is meshed with said carrier gear.
