AI Technical Summary

Technical Problem

The existing flip-plate drive mechanism results in a large gap between the flip plate and the end of the conveyor, which easily leads to paper jams and affects printing efficiency.

Method used

The flipping drive mechanism, which includes a frame, drive module, drive rod, and elastic reset mechanism, achieves regular intermittent opening and closing of the flip plate through the cooperation of the drive wheel and drive rod. Combined with the elastic reset mechanism, it stabilizes the swing of the drive rod, ensuring that the flip plate fits snugly with the conveyor and reducing the gap.

Benefits of technology

It effectively reduces the gap between the flip plate and the conveyor, lowers the probability of paper jams, improves printing efficiency, and enables status detection through a detection switch, making structural maintenance convenient.

Claims

1. A flip drive mechanism, characterized by, include: A frame, including a pivot for connecting to a flip plate; The drive module includes a drive wheel hinged to the frame, the outer periphery of which has a trigger portion protruding from its outer periphery; A drive rod is located around the drive wheel, with one end of the drive rod fixed to the end of the rotating shaft and the other end suspended in the air; The elastic reset mechanism has one end fixed to the frame and the other end fixed to the suspended end of the drive rod; When the trigger part abuts against the drive rod, the drive rod swings and drives the rotating shaft to rotate, and the rotating shaft drives the flap to open or close. After the trigger part separates from the drive rod, the elastic reset mechanism pulls the drive rod to reset.

2. The flip drive mechanism of claim 1, wherein, The drive module also includes: The motor is mounted on the frame; A pulley is rotatably connected to the frame, and the pulley is connected to the output shaft of the motor via a conveyor belt. The drive wheel and the pulley are coaxially fixed together.

3. The flip drive mechanism of claim 1, wherein, The driving wheel is a cam, and the eccentric part of the cam forms the trigger part; Alternatively, the driving wheel can be an elliptical wheel, with the trigger portion formed at both ends of the elliptical wheel on the major axis.

4. The flip drive mechanism of claim 1, wherein, The drive wheel is a circular wheel, and a protrusion is fixed to the outer periphery of the drive wheel, forming the trigger part.

5. The flip drive mechanism of claim 1, wherein, The drive lever includes: The rod body is connected between the rotating shaft and the elastic reset mechanism; The mounting part is provided on the rod body; A roller is rotatably connected to the mounting part. The roller is located on the side of the rod facing the frame and is used to abut against the trigger part.

6. The flip drive mechanism of claim 5, wherein, The mounting part is a bolt that is threaded into the rod body, and the head of the bolt and the rod body are used to limit the roller at both ends of the roller.

7. The flip drive mechanism of claim 1, wherein, The elastic reset mechanism is a tension spring.

8. The flip drive mechanism of claim 1, wherein, The flipping drive mechanism further includes: A detection switch having a notch, wherein a transmitter and a receiver are respectively provided on opposite side walls of the notch; A detection plate is fixedly connected to the rotating shaft. When the flip plate switches between the open and closed states, the detection plate blocks the space between the transmitter and the receiver.

9. The flip drive mechanism of claim 8, wherein, The frame is provided with a mounting bracket, which has a strip-shaped hole. The detection switch is mounted in the strip-shaped hole and can be adjusted in the direction of approaching or moving away from the frame.

10. A printing press characterized by Includes the flipping drive mechanism as described in any one of claims 1-9.
