Description

Edge twisting mechanism

Technical Field

The utility model relates to the technical field of jacquard opening equipment, in particular to a selvedge twisting mechanism.

Background

In the field of textile shedding devices, jacquard machines are provided with selvedge mechanisms, in order to achieve the action of two sets of up-and-down opposite movements, the timing of which can be adjusted individually (sometimes earlier than the opening of a normal shedding, and earlier than the closing). The upper end of the harness cord is connected with a selvedge twisting mechanism of the jacquard, and the lower end is connected with the upper end of the heald. The selvedge twisting mechanism drives the two harness cords to reciprocate up and down so as to realize the up-and-down movement of the two groups of healds.

The traditional machine type uses a passive cam rocker structure to realize the reciprocating swing of a rocker, is connected with a harness cord after being amplified by a lever, and can cause the impact of a roller and a cam to generate larger noise because of the condition that the tension of a return spring fixed at the lower end of a harness cord is insufficient or the roller and the cam are separated due to inertia force when equipment runs at high speed, even the roller or the cam is damaged, and the harness cord is easy to wear at the binding position of the harness cord and the rocker.

Aiming at the defects existing in the prior art, one of the purposes of the utility model is to provide a selvedge twisting mechanism which has the advantage of avoiding the abrasion of a harness cord at the binding position of the harness cord and a rocker.

The above object of the present utility model is achieved by the following technical solutions:

the utility model provides a hank limit mechanism, includes the base plate, the base plate on rotate and be connected with the driving shaft, the base plate on still rotate and be connected with the driven shaft, the driving shaft drive the driven shaft rotate, the driven shaft on be equipped with the rocking arm, the rocking arm on rotate and be connected with the swivel becket, the swivel becket on be equipped with the cambered surface, the cambered surface be annular.

By adopting the technical scheme, in use, as the cambered surface is arranged on the rotating ring and is annular, the harness cord is bound in the cambered surface of the rotating ring and does not move relative to the rotating ring, and therefore the advantage that the harness cord is easy to wear at the binding position of the harness cord and the rocker can be avoided.

The present utility model may be further configured in a preferred example to: the rocker arm on be equipped with the adjustment tank, the driven shaft on be connected with the regulating part, the regulating part keep away from the one end of driven shaft and the interval between the driven shaft adjustable, the regulating part pass the adjustment tank, be used for with the rocker arm fixed on the driven shaft.

By adopting the technical scheme, namely in use, the size of the opening of the twisted edge can be adjusted by adjusting the connection position of the rocker arm and the driven shaft.

The present utility model may be further configured in a preferred example to: and the base plate is also provided with a yielding groove which is used for enabling the rocker arm in a rotating state to pass through.

Through adopting above-mentioned technical scheme, the existence of the groove of stepping down for the rocking arm is easier to rotate, and the structure is compacter.

The present utility model may be further configured in a preferred example to: the two rocker arms are respectively positioned at two ends of the driven shaft, and the installation directions of the two rocker arms are 180 degrees.

By adopting the technical scheme, the effect is better.

The present utility model may be further configured in a preferred example to: the driving shaft and the driven shaft realize transmission through a synchronous belt pulley.

By adopting the technical scheme, the synchronous belt transmission is flexible transmission, and has no rigid contact, so that the possibility of collision is eliminated.

The present utility model may be further configured in a preferred example to: the base plate is also provided with a guide plate, and the guide plate is provided with a guide hole corresponding to the rotating ring.

Through adopting above-mentioned technical scheme, the existence of guiding hole makes can play good guide effect to leading to the silk rope.
