Pre-beating device of carbon fiber multi-layer angle knitting machine

Abstract

The invention relates to a pre-beating-up device of a carbon fiber multi-layer diagonal weaving machine. The pre-beating-up device is characterized by comprising a negative-pressure suction nozzle mechanism, a swing bearded needle mechanism and a crank block weft sending mechanism. The crank block weft sending mechanism comprises a stepping motor, a crank, a connecting rod and a sliding block moving plate. The stepping motor is fixed to a connecting plate. An output shaft of the stepping motor is in key connection with one end of the crank. The other end of the crank is in pin connection with the connecting rod. The other end of the connecting rod is in pin connection with the sliding block moving plate. The sliding block moving plate is fixedly connected with a first linear sliding rail. The swing bearded needle mechanism is connected with the crank block weft sending mechanism. The negative-pressure suction nozzle mechanism is arranged at a carbon fiber cloth weaving port through a support, and a negative-pressure suction nozzle center of the negative-pressure suction nozzle mechanism is aligned with a bearded needle point. The pre-beating-up device has the advantages that two sets of pre-beating-up devices symmetrically installed on the two sides of the carbon fiber multi-layer diagonal weaving machine are utilized, one-time pre-beating-up is carried out on each weft yarn, and it can be guaranteed that the weft yarn can be in a spreading state all the time.

Description

technical field [0001] The invention belongs to a carbon fiber multilayer corner loom, in particular to a pre-beating device of a carbon fiber multilayer corner loom. Background technique [0002] The weft-hanging action part of the carbon fiber multi-layer angle knitting machine includes hooking the weft yarn, moving the hook needle, and dewefting the hook needle. The above actions must be repeated for each weft yarn, and finally the weft is beaten. see attached Figure 6 , the beating process is the weft yarn introduced into the shed by the weft inserter on the loom, and there is a distance from the weaving mouth. It must be pushed to the weaving mouth and warp yarn by means of a reed to form interweaving. After several subsequent beatings, this weft yarn Stabilized to form the fabric together with the warp yarns, this motion of pushing the weft yarns towards the fell is called the beating motion. The carbon fiber multi-layer angle knitting machine is a 30-layer weaving m...
