[0005] To solve the problems existing in the prior art, the utility model provides a printing plate roller upper roller device which comprises a rack and a chassis, an upper roller frame is arranged on the rack through a lifting assembly, one side of the upper roller frame is provided with an adjusting groove, one side of the adjusting groove is provided with an adjusting motor, a shaft rod is movably arranged in the adjusting groove, a swing arm is connected to the outer periphery of the shaft rod through an adjusting rod, and a gear structure is further connected to the outer periphery of the shaft rod.

[0006] Further, the gear structure comprises a driving gear and a driven gear set, the driving gear is sleeved on the shaft rod, the driven gear is engaged with the driving gear set, and a lead screw is drivingly connected to the driven gear set.

[0007] Further, the lead screw is located in the interior of the upper roller frame, and a moving groove is formed in the upper roller frame above the lead screw.

[0008] Further, a limiting plate is movably arranged on the moving groove, and the bottom of the limiting plate is slidingly connected to the lead screw through a sliding block.

[0009] Further, one end of the shaft rod is connected to the output end of the adjusting motor.

[0010] Further, the lifting assembly comprises a lifting motor and a lifting screw rod, the lifting screw rod is movably arranged on the rack and connected to the output end of the lifting motor above the rack, and the upper roller frame is slidingly connected to the lifting screw rod through a lifting sliding block.

[0011] Furthermore, a push rod is provided above the frame, and a universal pulley is provided at the bottom of the base frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. After the adjustment motor of the utility model is started, it drives the shaft to rotate clockwise, and the clockwise rotation of the shaft drives the adjustment rod and the swing arm to adjust upward. After the swing arm is adjusted to a certain angle, it conflicts with the printing paper outside the printing plate roller, and cooperates with the limit plate to clamp and limit the printing plate roller, thereby preventing the printing plate roller from loosening, deflecting, and falling during movement and transportation.

[0014] 2. When the lower roller needs to be operated, the shaft is driven to rotate counterclockwise by adjusting the motor, and the swing arm is driven to adjust downward by the counterclockwise rotation of the shaft until the tail end of the swing arm is adjusted to touch the ground or the material receiving device. At this time, the two sets of inclined swing arms act as oblique guide plates for unloading, and during the counterclockwise rotation of the shaft, the gear structure synchronously drives the limit plate to move toward the swing arm. The moving limit plate can push the printing plate roller on the upper roller frame to roll, and cooperate with the inclined swing arm at this time to assist in unloading, thereby reducing the workload of the staff and increasing the practicality of the device.
