The pinch roller 4 continues to descend, the front end part of the guide surface 101 descends along with the pinch roller, and the rotating shaft 7 is driven to rotate in the mounting hole 501 on the left disc 5 of the automatic layer winding machine.
In the process of continuing to descend the pinch roller 4, the guide block 10 rotates around the central line of the rotating shaft 7 until the piston rod of the air cylinder 2 extends out to reach a preset stroke.

As shown in fig. 3, a guide stopper 602 and a stopper 601 are provided on the fixed block 6. The guide stop 602 is provided with a smooth curved surface or ramp. A smooth curved surface or inclined surface on the guide block 602 and the block 601 form a gap 603 for the wire 004 to pass through, and the gap plays a guiding role when the wire 004 is penetrated.
The cambered surface on the stop block 601 can increase the gap between the guide stop block 602 and the guide stop block, so that the wire 004 can pass through the guide stop block, and the surface damage of the bent wire 004 can be prevented. The front end of the block 601 is provided with a protrusion 6011, and in an initial state, a gap 604 between the protrusion 6011 and the movable block 8 is the smallest.
Optionally, the guide stop 602 and the stop 601 are two or more parts, and are used in cooperation with the movable block 8.
As shown in fig. 5, when the pressing wheel 4 descends to contact with the guide surface 101 of the guide block 10 and the torsion spring 9 is compressed, and the wire 004 is ready to penetrate into the bending mechanism, along the penetrating direction of the wire 004, the smooth curved surface or inclined surface of the guide stop 602 is slightly higher than the movable block 8 and lower than the stop 601, so that a gap for the wire 004 to pass through is formed among the guide stop 602, the stop 601 and the movable block 8.
As shown in fig. 6, the pressing wheel 4 is raised, the guide block 10 is raised to drive the rotating shaft 7 and the movable block 8 to rotate in opposite directions, in the process, the movable block 8 is gradually higher than the curved surface or the inclined surface of the guide stop 602, and when the movable block 8 rotates to the stop 601, the protrusion 6011 of the stop 601 gradually reduces the gap 604 between the movable block 8 and the stop 601;
when the pressing wheel 4 is separated from the guide block 10, the torsion spring 9 is in an initial state, and the gap 604 between the movable block 8 and the stop block 601 is minimized. At this time, the wire 004 is clamped by the stopper 601 of the fixed block 6 and the movable block 8.
The working process of the invention is as follows:
the stroke of the piston rod in the lifting mechanism and the working time of the piston rod are preset.
The grip bending mechanism is mounted on the left tray 5 of the automatic layer winding machine, and the plastic tray 002 is fixed to the layer winding machine, and as shown in fig. 5, the threading hole 003 of the plastic tray 002 is mounted on one side of the bending mechanism.
After the mechanical arm is provided with the plastic plate 002, the cylinder 2 in the lifting mechanism is started, the piston rod of the cylinder extends downwards, the connecting seat 3 is arranged on the joint of the cylinder rod, and the connecting seat 3 drives the pressing wheel 4 to move downwards. The puck 4 first contacts the front end of the guide surface 101 of the guide block 10. as shown in fig. 5 and 6, the guide surface 101 is a smooth transition surface. The cylinder rod of the cylinder 2 continues to extend, and the pressing wheel 4 continues to press the front end of the guide block 10 downward and gradually rotates to contact the middle portion of the guide surface 101. In the whole process, the front end of the guide block 10 gradually descends, the guide block 10 drives the rotating shaft 7 to rotate, and the piston rod stops extending until the piston rod of the air cylinder 2 reaches a preset stroke.
In the process that the pinch roller 4 presses the guide block 10 downwards, the extending arm B902 at one end of the torsion spring 9 always rotates around the central axis of the rotating shaft 7 together with the guide block 10, namely, the extending arm B902 is closer to the outer edge of the central circular shaft 005 of the left plate 5 of the layer winding machine, the extending arm a901 at the other end is always tangent to the outer edge of the central circular shaft 005 of the left plate 5 of the layer winding machine, namely, the position of the extending arm a901 is not changed. At this time, the included angle between the two end extending arms a901 and B902 is gradually reduced, the torsion spring 9 is compressed, and the gap between the movable block 8 and the fixed block 6 through which the wire 004 passes is the largest.
At this moment, the mechanical handle wire 004 of the layer winding machine passes through the threading hole 003 on the plastic plate, enters the gap between the guide stop 602 and the stop 601, penetrates inwards along the guide stop 602 under the action of the guide stop 602, and the wire 004 can smoothly pass through the guide stop 8 and extend out for a certain distance because the movable block 8 is lower than the surface of the guide stop 602.
As shown in fig. 6, after the threading of the manipulator of the layer winding machine is completed, the piston rod of the cylinder 2 contracts to drive the connecting seat 3 arranged on the cylinder rod joint to move upwards and drive the pressing wheel 4 to move upwards, the guide inclined plane of the pressing wheel 4 and the movable block 8 is separated, the torsion spring 9 resets under the action of the spring force to drive the rotating shaft 7 and the movable block 8 to rotate reversely, and the lifting mechanism is restored to the initial state.
Under the spring force of the torsion spring 9, the gap between the stopper 601 and the movable block 8 gradually decreases. When the torsion spring 9 is restored to the initial state, the fixed block 6 and the movable block 8 act together to clamp and hold the wire rod at a certain angle, so that the holding and bending action is completed, and the automatic cylinder layer winding machine starts to wind.
After the wire rod winding on the plastics dish is finished, the motor stop work layer is around quick-witted left side dish at assigned position stall, 2 cylinder rods of pinch roller cylinder stretch out the connecting seat 3 that drives the cylinder rod joint setting this moment and move down to drive pinch roller 4 and descend, pinch roller 4 and the spigot surface 101 contact of guide block 10, the both ends of torsional spring 9 stretch arm A901 and stretch arm B902 and are compressed, and pivot 7 and movable block 8 rotate and the gap between the fixed block 6 increases to the biggest. When the plastic disc is taken out, the held hook is separated from the gap between the movable block 8 and the fixed block 6, and the wire take-up process is completed.
