The rowing mechanism of the pinecone machine

Abstract

The invention discloses a wool top arranging mechanism of a ball top bulking machine. The wool top arranging mechanism comprises a sine mechanism composed of a guide rod, a linear ball guide rail, a ball guide block and a crank. One end of the guide rod is connected to the linear ball guide rail horizontally arranged, a sliding groove is vertically formed in the other end of the guide rod, the ball guide block is connected in the sliding groove, the ball guide block is connected to the crank through a pin shaft, and the crank is driven to rotate through a motor. The crank and the linear ball guide rail are fixedly arranged on a rack. The wool top arranging work of wool tops is carried out through the sine mechanism, due to the facts that the displacement of the guide rod is in a sinusoid and the accelerated speed of the guide is also in a sinusoid, an acceleration curve is continuous, the discontinuity points of the accelerated speed do not exist, the change of force at two end points is mild, the wool tops cannot generate accidental drafting, and finished ball top quality is guaranteed.

Description

technical field [0001] The invention relates to a rowing mechanism used in a pinning machine of chemical fiber and wool spinning equipment. Background technique [0002] Wool tops or fur balls or chemical fiber balls produced by chemical fiber factories have relatively high ball forming tension and ball forming pressure, and poor bulkiness of unmachined hair balls. If such hair balls are directly dyed, the penetration of the dye solution to the hair balls will be seriously affected. After dyeing, dyeing defects such as color difference, color flower and uneven dyeing are easy to appear. For this reason, before dyeing, it is necessary to use a pinecone machine to make the fibers swell to ensure the dyeing quality. [0003] The rowing mechanism of the existing pinecone machine adopts the slider crank mechanism, and the sudden change of the acceleration at the two end points will generate a large impact force, especially after the mechanism parts are worn, the impact force is...

Problems solved by technology

[0003] The rowing mechanism of the existing pinecone machine adopts the crank slider mechanism, and the sudden change of the acceleration at the two end points will produce a large impact force, especially after the mechanism parts are worn, the impact force is even greater, so that the In the end position, the top is prone to accidental drafting, resulting in uneven tension of the hair ball and affecting the dyeing quality
