Problems solved by technology

The traditional beat-up mechanism uses a blade to interrupt the weft thread through the cam mechanism. With this structure, each time the weft is beaten, especially for some relatively strong and thick weft threads, the beating-up mechanism will be subject to greater resistance when the blade cuts. In order to ensure the smooth progress of beating-up, the traditional beating-up mechanism needs to have a large driving power all the time, resulting in a large waste of energy, and because the beating-up mechanism only has a large power at the moment of beating-up, the overall force component Periodic changes, the force is not balanced enough, so that the uneven force of the beating mechanism is easy to damage, and when the weft is relatively thick, it affects the speed and quality of beating, which in turn affects the entire weaving efficiency and weaving effect

Abstract

The invention provides an impact type high-speed weft cutting device which comprises a rotating rod, an impact ball, an impacted block, an upper shearing tool bit and a lower shearing tool bit, wherein the rotating rod is driven by a driving device to rotate; the outer end of the rotating rod penetrates into the impact ball; the impact ball is connected with the inner side of the rotating rod through a spring sleeving the rotating rod; the impacted block can be assembled at the lower part of the rotating rod in the manner of sliding up and down; with the rotation of the rotating rod, the impact ball and the impacted block periodically collide; wefts to be cut penetrate through a position between the upper shearing tool bit and the lower shearing tool bit. The impact type high-speed weft cutting device can quickly finish a weft knitting process in an impact mode; in the weft knitting process, energy can be accumulated and then released at a time, so that the whole weft knitting mechanism is higher in energy utilization rate.

Description

Technical field [0001] The invention belongs to the technical field of textile machinery, in particular to an impact type high-speed weft cutting device. Background technique [0002] The fabric is made of silk threads woven through a warp and weft structure. In the specific weaving process, the warp threads are usually placed side by side, and then the weft threads are used to cross between the warp threads. Today's fabrics are usually woven by machines. When the current textile machines are weaving fabrics, the weft threads of the fabric are usually inserted from one side of the warp threads, and the weft threads are interrupted when the end of the weft threads reaches the other side of the warp threads. Then the warp threads cross the weft threads again as they are staggered open again. The traditional beating-up mechanism uses the blade to break the weft through the cam mechanism. With this structure, during each beating, especially for some relatively strong and sturdy...
