Ink supply system with planetary reduction cam device

Abstract

The invention provides an ink supply system with a planetary deceleration cam device. The ink supply system includes a spindle, a sun gear, a small gear, an internal tooth cam, a cam driven part and aswing arm, one end of the spindle is arranged in a side wall, the other end of the spindle is supported by a gear shaft support, the sun gear and the internal tooth cam are coaxially arranged on thespindle, a shaft seat is arranged on the spindle through a bearing in an empty sleeving mode, a small gear shaft is fixedly arranged in the shaft seat, the small gear sleeves the small gear shaft in an empty mode, the small gear is engaged with the sun gear and the internal tooth cam, the sun gear drives the small gear to rotate, the small gear drives the internal tooth cam to rotate, and the internal tooth cam drives the swing arm to move through the cam driven part. The ink supply system has the beneficial effects that the transmission ratio of a swing cam of an ink transfer roller is lowered; impact force is reduced, work stability of an ink distribution system is improved, and the fault rate of equipment is lowered; ink transferring time is increased, the ink distribution effect is improved, and the bright-clean degree of printing product lines is improved; and the ink transferring time of the ink transfer roller is reduced, misting is effectively lowered, and the printing ink costis saved.

Description

Technical field [0001] The invention relates to the field of banknote printing and coinage, and more specifically to an ink supply system with a planetary deceleration cam device. Background technique [0002] The swing of the ink transfer roller of the inking system of the printing press controls the cam mechanism. In this field, the swing of the ink transfer roller is realized by gear grading deceleration, chain deceleration, and servo motor speed control. [0003] The gear stepped reduction drive cam cannot reach the ideal speed. For example, the J98 machine has the following disadvantages in use: [0004] 1. The inertial impact is large and the mechanism is noisy; [0005] 2. The rubber roller ages quickly and is easy to fall off; [0006] 3. There are many times of ink separation and ink flying phenomenon is serious. [0007] After the chain is decelerated, the transmission control cam has the following drawbacks in use: large space occupation, complex structure, poor stability, no...

AI Technical Summary

Problems solved by technology

[0004] 1. The inertial impact is large and the noise of the mechanism is large;

[0005] 2. The rubber roller ages quickly and is easy to lose glue;

[0006] 3. There are many times of ink separation, and the phenomenon of flying ink is more serious

[0007] After the chain is decelerated, the transmission control cam has the following disadvantages in use: it takes up a lot of space, the structure is complicated, and the stability is poor. It is not suitable for high-speed machines.

[0008] After the servo motor speed is adjusted, the transmission control cam realizes the swing of the ink transfer roller, which has the following disadvantages in use: large space occupation, complex structure and high cost
