the processing technology of the rapier loom for the waterproof cloth of the kayak comprises the following specific processing technologies:
1): firstly, setting weft insertion parameters by a worker through a display screen of a control device according to production requirements;
2): then the corresponding waterproof wire passes through the winding roller (2), namely passes through the driving roller (22) and then passes through the wire routing device (6) on the traction roller (23);
3): the waterproof wires passing through the winding roller (2) respectively pass through the corresponding first routing plate frame (31), the second routing plate frame (32) and the baffle wire frame (43), and the waterproof wires passing through the baffle wire frame (43) are finally fixed on the winding mechanism (5);
4): in the working process, the corresponding lead screws are driven to rotate by lead screw driving motors on the first wiring plate frame (31) and the second wiring plate frame (32), the first wiring plate frame (31) and the second wiring plate frame (32) are driven to move up and down in a reverse direction by a lead screw driving sliding block, and two groups of waterproof wires are crossed and separated;
5): then, the weft insertion driving mechanism drives the weft insertion sword (41) and the weft insertion sword (42) to start working, namely, the air cylinder drives the rapier (411) to drive the weft insertion line to move forwards, and in the process, the air cylinder drives the weft insertion sword (42) to move relative to the weft insertion sword (41);
6): when the weft receiving sword (42) contacts the thread end of the weft guiding thread on the weft feeding sword (41), the air cylinder drives the jointing clamp (422) to open and joint the thread end, then the driving cylinder of the weft receiving sword (42) retracts, and when the weft guiding thread passes through the space between two layers of waterproof threads, the air cylinder drives the jointing clamp (422) to release;
7): then a wire blocking frame (43) driving mechanism drives the wire blocking frame (43) to move forward, and the weft guiding line is pushed to the intersection of the two layers of waterproof lines;
8): in the above process, when the binding clip (422) releases the weft thread, the cutting mechanism (416) will cut the thread on the weft thread roll.
