Description

Technical Field

[0001] The utility model relates to the technical field of spinning frames, in particular to a novel holding type spindle brake for a spinning frame. Background Art

[0002] The structure of the existing spinning machine brake spindle includes the following structure. Patent No. CN211713283U discloses a spinning machine clamping spindle brake, including a brake spindle block and a brake spindle frame. The lower surface of the brake spindle frame is provided with irregular grooves. The brake spindle frame includes a working part, an inclined part and a handle part. The working part extends in a horizontal direction, and the inclined part forms an upward slope from the rear end of the working part to the rear, and the handle part extends from the rear end of the inclined part to the rear along the horizontal direction. The other end side of the working part has an arc-shaped connecting cavity for connecting the brake spindle block. Two claw fixing plates are symmetrically provided at the lower end of the working part. The claw fixing plates are perpendicular to the horizontal part of the working part. Claws are fixed on the inner sides of the two claw fixing plates. The brake spindle frame is installed on the spindle disk through two claws. Rectangular brake spindle grooves matching the two claws are opened on both sides of the lower end of the spindle disk.

[0003] Most of the existing spindle brakes are single-point locking hoops. When the brake spindle groove contacts the yarn shaft during locking, there is no buffer. At this time, the rotational force of the rotating yarn shaft will cause greater wear on the brake spindle groove. Over time, the firmness of the brake hoop will be reduced, and the rotational impulse directly acts on the brake spindle groove because there is no buffer. The brake spindle groove is subjected to excessive wear and tear, which will affect its service life. Utility Model Content

[0014] 2. By setting an arc-shaped buffer plate and a buffer spring, when the spindle is braked, the impact force generated by the rotation of the yarn shaft contacts the buffer plate, and the arc-shaped buffer plate deviates outward on the left and right sides of the buffer spring to relieve part of the impact force. At this time, the rotation speed of the yarn shaft will be reduced under the restriction of the arc-shaped buffer plate, so that the impact force is reduced. At this time, the brake spindle groove will not cause greater wear when it is stuck on the yarn shaft, which is beneficial to reduce the wear of the fine yarn shaft on the brake spindle and increase the service life of the brake spindle.
