Bobbin yarn conveying device

Abstract

The invention discloses a bobbin yarn conveying device. The bobbin yarn conveying device comprises a conveying belt used for conveying bobbin yarn and shearing mechanisms used for shearing yarn bodiesscattered on the bobbin yarn; and the shearing mechanisms comprise baffles, scissors and driving mechanisms, wherein the baffles are arranged on one side of the conveying belt, and negative pressuresuction holes capable of sucking the yarn bodies on the bobbin yarn into the outer sides of the baffles are formed in the plate surfaces of one sides, facing the conveying belt, of the baffles, the scissors are positioned on the outer sides of the baffles, and the driving mechanisms are used for driving the scissors to shear the yarn bodies entering the outer sides of the baffles. After the bobbinyarn enters the conveying belt, in the conveying process of the bobbin yarn, negative pressure is generated at the positions of the negative pressure suction holes when the bobbin yarn passes throughthe shearing mechanisms, so that the floating yarn bodies are absorbed and pass through the negative pressure suction holes, and the driving mechanisms drive the scissors to shear and remove the yarnbodies which are absorbed through the negative pressure. According to the bobbin yarn conveying device, the bobbin yarn can be trimmed while the bobbin yarn is conveyed, so that the working efficiency is greatly improved, and the bobbin yarn can be trimmed in order.

Description

technical field [0001] The invention belongs to the technical field of yarn processing, and in particular relates to a bobbin yarn conveying device. Background technique [0002] In the industrial production process, yarn production generally includes the following processes: (1) Spinning stage: generally ring spinning, producing bobbin yarn, bobbin yarn includes bobbin and yarn wound on the bobbin ; (2) Winding process: the yarn is unwound from the bobbin, its defects are removed and then wound into a package, which contains a greater number of yarns. The winding process is much faster compared to spinning, so that a small number of winding units or winding stations, on the order of a few dozen, enables the production of a large number of yarn units on the order of several thousand. Generally, the bobbin from the spinning machine is wound with its yarn end around the bobbin package or the bottom of its tube for a specified number of revolutions, the bobbin yarn end cut fro...

Problems solved by technology

When inserting the end of the yarn into the bobbin, it is necessary to trim the excess yarn floating on the bobbin yarn. Usually, in the prior art, the bobbin yarn needs to be transported to the trimming place by a conveying device, and then trimmed by a trimming device. This method is time-consuming and labor-intensive, and the efficiency is low
