Abstract
The utility model relates to a thread feeding device, which belongs to thread feeding equipment for a knitting machine. The utility model is characterized in that thread feeding wheels are directly connected with stepping motors through a shaft, a speed variator can be arranged between stepping motors and thread feeding wheels, when drive pulses are conveyed in parallel by a set of thread feeding wheels which are of the same structure, the same size and the same safety and are provided with the stepping motors with identical specifications, the set of thread feeding wheels can convey yarn with identical lengths and are fully synchronized. The utility model overcomes the defect that the rotations of the thread feeding wheels are not synchronized because of the elastic deformation of belt drive and is especially suitable for knitting loop wheel machines.
Description
The utility model belongs to a kind of knitting machine yarn-feeding device.
Before the utility model was realized, existing Thread-feeding device adopted belt transmissioning mode, and same group of several to dozens of defeated yarn wheel for requiring the synchronous yarn feeding of equivalent drags with same cog belt.The shortcoming of this mode is: (1) complex structure, and syringe is changed in inconvenience when being used for chassis; (2) when need being divided into many groups by the yarn feeding amount, the defeated yarn wheel of same syringe is difficult to realize.So,, fail on chassis, to promote though above-mentioned belt driven type Thread-feeding device has come out for many years always.
The purpose of this utility model provides a kind of Thread-feeding device, thereby has solved the problem that above-mentioned prior art exists.
Solution of the present utility model is: defeated yarn wheel directly is connected with axle with stepper motor.Between stepper motor and defeated yarn wheel, a speed changer can also be set.When being assembled with the identical defeated yarn wheel of the physical dimension of same size stepper motor with the pulse of parallel way feed drive to one, this group Thread-feeding device will the identical yarn of delivered length, and fully synchronously.Different with prior art is, the utility model directly transmits signal with stepper motor to defeated yarn wheel, thereby it is simpler than belt transmission structure, easy for installation, be not subjected to the restriction of bang path, also overcome the belt transmission strain and caused defeated yarn wheel to rotate nonsynchronous shortcoming, be particularly suitable for using on the knitting bogie.Driving system of stepping motor can electronic computer control, this computer can be exported the relevant stepper motor driving pulse of multichannel simultaneously, thus can realize same syringe easily multiplely advance the yarn amount, for the exploitation designs and varieties are laid a good foundation.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Accompanying drawing 1 is the schematic diagram of a kind of embodiment of the utility model.
Accompanying drawing 2 is the schematic diagram of second kind of embodiment of the utility model.
The structure of embodiment 1 is as shown in Figure 1: stepper motor 1 and defeated yarn wheel 2 are connected with axle 3, and yarn 4 is wrapped in defeated yarn and takes turns.When stepper motor is accepted a driving pulse 5, drive defeated yarn wheel and rotate a fixing angle thereupon, the one section fixing length of then moving of the yarn on the defeated yarn wheel.To the pulse of stepper motor feed drive, defeated yarn wheel will drive the yarn continuous motion, thereby realizes continuous yarn feeding as constantly.
The structure of embodiment 2 is as shown in Figure 2: stepper motor 1 is connected with axle 3 with the driving wheel 7 of speed changer 6, and defeated yarn wheel 2 is connected with axle 8 with the driven pulley 9 of speed changer, and yarn 4 is wrapped in to be failed yarn and take turns.When stepper motor is accepted a driving pulse 5, rotates a fixing angle, drive defeated yarn by speed changer and take turns and rotate another angle in proportion regularly, the yarn one section fixing length of then correspondingly moving.Described speed changer can be gear-shift mechanism, and gear is preferably helical teeth, to guarantee stable drive and to reduce noise.
When using embodiment 1, when the rotating speed of stepper motor is lower than the desired defeated yarn wheel speed of technology, can use the embodiment shown in the embodiment 2.
Claims (2)
1. a Thread-feeding device is characterized in that defeated yarn wheel directly is connected with axle with stepper motor.
2. Thread-feeding device according to claim 1 is characterized in that between described defeated yarn wheel and the stepper motor speed changer being set.
