Description
Technical Field
[0001] The utility model relates to the technical field of drawing frames, in particular to a drawing frame with adjustable tension. Background Art
[0002] A drawing frame is a spinning machine that processes multiple carded or combed fiber strips into fiber strips with certain quality requirements.
[0003] When the yarn is processed by the drawing frame body during the yarn production process, several yarns will be interlaced and passed through the outer surfaces of several tension rods, and then put into the drawing frame body for drawing processing. The processed yarn will be rolled in a drum. Since the general drawing frame body pushes the drum out of the barrel through the pushing mechanism installed on the drawing frame body when it is unbobbed, and the pushing mechanism can only push but cannot limit it, the drum is in an unstable state during the pushing and pushing process, and it is easy to tip over under the action of inertia, causing the internal drawn and rolled yarn to scatter, thereby affecting the later use of the drawing frame body.

The drum moves to a certain position and is placed on the turntable. At this time, the second electric telescopic rod is started to drive the first clamping block and the second clamping block to loosen the drum.

[0035] Working principle: when the yarn is processed by the drawing frame main body 1 during the yarn production process, the drum 4 is first placed on one side of the drawing frame main body 1 between the first clamping block 26 and the second clamping block 28, and then the second electric telescopic rod 23 is started to drive the I-shaped block 24 to move to a certain position at one end, and the two ends of the rotating rod 25 are respectively rotated to a certain position in the inner wall of the I-shaped block 24, the first clamping block 26 and the second clamping block 28, and then one end of the first clamping block 26 and the second clamping block 28 is rotated to a certain position on the pushing rack 22 with the rectangular hole 27 as the center, so that both ends of the first clamping block 26 and the second clamping block 28 are contracted inwardly to clamp and fix the drum 4, and then the first electric telescopic rod 21 is started to drive the pushing rack 22 and the clamped drum 4 to move to the inner wall of the drawing frame main body 1.
