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
The invention belongs to multilayer carbon fiber angle connection loom, particularly relate to the pre-beating device of a kind of multilayer carbon fiber angle connection loom.
Background technology
Multilayer carbon fiber angle connection loom is hung latitude action part and is comprised that crochet hook tangles weft yarn, crochet hook moves and crochet hook sluff-offs, and every root weft yarn all will repeat above-mentioned action, finally beats up.Refer to accompanying drawing 6, technique of beating up is introduced the weft yarn of shed open on loom by weft insertion device, with fell has a segment distance, fell and warp thread must be pushed it against by reed to be formed and interweave, through beating up subsequently several times, this weft yarn settles out and jointly forms fabric with warp thread, and this motion weft yarn being pushed to fell is called as beating motion.Multilayer carbon fiber angle connection loom 30 layers of being are weaved, 20000, warp thread, weft yarn 30, initial warp thread is in flattened state, through the pulling force effect of heald, forms opening shape below, weft yarn passes from centre, and crochet hook hooks weft yarn, and weft insertion device moves back latitude, crochet hook sluff-offs, define weft yarn free end, harness eye drives movement of the warp, carries out the braiding of later layer through weft yarn, make front one deck weft yarn two ends form free end, mid portion weft yarn easily occurs curling.Due to movement of the warp, make weft yarn amount of deflection there occurs change, and so forth, discharge front one deck weft yarn, hook the action of later layer weft yarn, occurred bending, finally defined the flaw of cloth cover.Because the fill yarn ends of carbon fiber is many, in movement of the warp process, when carbon fiber loom beating-up, the weft yarn between different weft layers also can be caused mutually to interfere.Above-mentioned factor all can cause carbon fiber heavy wear, causes cloth cover to produce irregular flaw, badly influences fabric quality.Carbon fiber knit industry weft yarn urgently to be resolved hurrily disturbs mutually and mid portion weft yarn volume causes carbon fibre fabric fabric quality to occur the problem of flaw.
Summary of the invention
The present invention is to overcome deficiency of the prior art, a kind of multilayer carbon fiber angle is provided to join the pre-beating device of loom, two cover symmetries are utilized to be arranged on the pre-beating device of multilayer carbon fiber angle connection loom both sides, respectively every latitude weft yarn is once beaten up in advance, make weft yarn before formally beating up, move to fell place.Can ensure that carbon fiber loom arranged pre-beating device before beating up, can ensure that weft yarn is in exceptionally straight state always.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of pre-beating device of multilayer carbon fiber angle connection loom, it is characterized in that: comprise negative pressure suction nozzle body, swing latch needle mechanism, crank block Song Wei mechanism, described crank block Song Wei mechanism comprises stepper motor, crank, connecting rod and slide block movable plate, described stepper motor is fixed on connecting plate, described stepper motor output shaft and crank one end keyed jointing, the described crank other end and connecting rod pin joint, the described connecting rod other end and slide block movable plate pin joint, described slide block movable plate and the first linear slide rail affixed, described swing latch needle mechanism comprises stepping ball screw framework, lifting moving plate, limiting cylinder, connecting rod and semi-circular crochet hook, described limiting cylinder is horizontally fixed on lifting moving plate, limiting cylinder is by cylinder connector and connecting rod pin joint, described connecting rod centrepin is connected on lifting moving plate center, the affixed semi-circular crochet hook of the described connecting rod other end, described lifting moving plate is connected with the guide pin bushing bolt of stepping ball screw framework, and described swing latch needle mechanism is connected with crank block Song Wei mechanism, described negative pressure suction nozzle body by being placed on carbon cloth cloth fell, during the negative pressure suction nozzle center of negative pressure suction nozzle body is relative with crochet hook needle point.
Described swing latch needle mechanism promotes avoiding mechanism by Z-shaped connecting plate with cylinder and is connected, described cylinder promotes avoiding mechanism and comprises promotion cylinder, L-type Connection Block and the second linear slide rail, described promotion cylinder is connected with slide block movable plate by L-type bearing, described promotion cylinder is connected with Z-shaped connecting plate, described Z-shaped connecting plate top is connected with swing latch needle mechanism, its underpart and the second linear slide rail affixed, the second linear slide rail and slide block movable plate affixed.
