Description

(54) MECHANISM OF TRANSFER OF MOVEMENT TO THE MOBILE BELT AT A MOBILE MOBILE.

The invention relates to the textile industry.

The mechanism for transferring the movement of the weaver to the loom is known, which contains a drive electrically connected to the machine’s stopping mechanism with a V-belt variator, one of the shafts of which is equipped with an end gear coupling and a worm gear, a device for adjusting the thread tension in the idle position of the machine 1.

A disadvantage of the known mechanism is that in order to realize the turn to the left, in the idle position of the machine, it is necessary to loosen the nut manually, thereby disconnecting the front toothed coupling halves and rotate the flywheel. And all this can be done only from the background of the machine. The listed remarks create inconveniences in the maintenance of the mechanism and a large amount of time associated with the transition of the worker to the safety plan of the machine for performing the above operations;

The purpose of the invention is to improve serviceability.

The goal is achieved by the fact that the mechanism for transferring the movement of the weaver to the loom contains an actuator electrically connected to the machine’s stopping mechanism with a belt variator, on one of the shafts of which there is an end gear coupling and a worm gear, a device for adjusting the thread tension in non-working the position of the machine, while adjusting the tension of the thread

10 in the off position of the machine includes a drive, kinematically connected to the output shaft of the variator electromagnet, electrically connected to the machine stop mechanism, and a double plate 15 arm, one end of which is installed with the possibility of interaction with one of the coupling halves and is spring-loaded to it, and the other is connected to the electromagnet core .

The mechanism for transmitting the movement of the weaver on the loom contains an individual electric motor 1 mounted on a plate 2, which is attached to the frame of the machine 3. On the shaft of the electric motor 1 a pulley 4 is rigidly set, which is connected with the pulley 6 fixedly mounted on the shaft 1 the output shaft of the variator 7. On the output shaft of the variator 7 with the possibility of axial shifting of eden, the end gear of the coupling half 8 is fitted, which is connected with the other iolumuftoy 9, which is free to sit on the output shaft of the variator 7 and represents one whole a movable cone of the variator. A spring 10 is installed between the pulley 6 and the face gear half coupling 8, which tends to engage the coupling half 8 and 9. The half end of the gear half of the coupling 8 is connected to one of the shoulders of the two shoulders 12. Another shoulder of the two shoulders 12 is connected by means of the pull 13 with the electromagnet 14. The same shoulder of the two shoulders lever 12 has the ability to contact the limit switch 15. The double shoulder lever 12 is freely seated on the axis 16. On the output shaft of the variator 7, the worm is rigidly set to 17, which is in engagement with the worm wheel 18, the Fully mounted on the drive shaft. On the same shaft, a subwoofer gear 19 is attached, coupled with the warp gear 20 and 21. 21. The mechanism for transferring weaving movement to the rope works as follows. When pressing one of the Base release or Base tensioning buttons, an electromagnet 14 is triggered, which, through pull 13, actuates the double-arm lever 12, turning the latter clockwise. The two shoulders lever 12, through the crackers 11, interact with the end gear coupling half 8, moving it along the output shaft of the variator 7 to the left and bringing it out of engagement with the other coupling half 9 and thereby breaking the kinematic link between the two and the V-belt variator. After uncoupling the end of the clutch to the left of the two shoulders of the lever 12, it contacts the end switch 15, closes the electric starting circuit of the electric motor. 6 rotational movement receives the output shaft of the variator 7, and consequently, the worm to 17, the worm gear from 18, the sub-war gear 19 and the war gear 20. Navoi 21 is set in motion clockwise or counterclockwise depending The stiffness depends on which button is pressed. Base release or Tension is based. After the button is released, the electrical connection circuit of the electromagnet is broken. The end camshaft half-coupling 8 under the action of the spring 10 moves to the right, engaging with the other half-coupling 9, the double-arm lever 12 rotates counterclockwise through the crunches 11, the shoulder B departs from the limit switch 15, the electric starting circuit is broken. The motor stops, and the investigator stops the beam 21. The use of the proposed mechanism on weaving machines completely eliminates the manual work associated with the release and tension of the main threads when the machine is not working, increasing productivity by eliminating the worker’s transitions to the back plane of the machine, in order to unscrew the mechanical gear coupling and perform tempering or tensioning operations of the base. Using the proposed mechanism, the weaver performs the tempering and tensioning operation of the base.
