High-speed shaftless driven metal tank printer

Abstract

The invention discloses a high-speed shaftless driven metal tank printer which comprises a machine base, a rear-section rack, a tank inlet mechanism, a mandrel rotary disc, a transmission disc, a gloss oil machine, a front-section rack, a rubber plate wheel, a printing plate roller and an ink conveying mechanism. The high-speed shaftless driven metal tank printer is characterized in that the mandrel rotary disc is mounted on the middle part of the rear-section rack; a plurality of sets of movable mandrel assemblies are uniformly mounted on the outer circle of the mandrel rotary disc; the gloss oil machine is mounted on the machine base at the right lower side of the mandrel rotary disc; one rubber plate wheel, a plurality of sets of printing plate roller assemblies and the ink conveying mechanism are mounted on the front-section rack; the printing plate roller assemblies, the rubber plate wheel, the mandrel rotary disc and the transmission disc are each equipped with a servo motor; a motion controller is arranged on each servo motor; and each servo motor is networked to a background through bus communication for being synchronously controlled. The high-speed shaftless driven metal tank printer adopts a shaftless transmission mode, saves a great number of mechanical components, saves cost, is low in energy consumption, is simple and convenient to mount, debug and maintain, is stable in operation, is high in synchronous regulating precision; and moreover, printing quality is reliable, printing specifications and patterns are easily replaced.

Description

technical field [0001] The invention relates to the technical field of metal can printing machines, in particular to a high-speed shaftless transmission metal can printing machine. Background technique [0002] The current metal can printing machines all adopt shaft transmission, and through a series of gears, shafts, belt drives, chain drives, transmissions, etc., the power and rotation of the motor are transmitted to each actuator as required to realize the printing function. Due to the long transmission path and numerous intermediate mechanisms, the following problems are caused: 1. High equipment cost; 2. The printing accuracy and speed are limited by the mechanical structure; 3. It is difficult to install and maintain, especially when changing printing specifications or patterns, the adjustment period is long. ; 4. The disturbance of any link in the transmission chain will affect the performance of the whole machine, which is easy to form error accumulation; 5. It is hi...
