The invention relates to a drum jet printing machine. It is composed of electric spray gun, motor, digital ring, disc brush and inner bracket. The digital ring is equipped with inner teeth and an outer seat for placing digital chips. The bracket is rolled and installed; the electromagnetic clutch gear of the motor is installed in mesh with the inner teeth of the digital ring. The electromagnetic clutch gear is controlled by the clutch electromagnetic, combined with the electromagnetic coil, and uniformly threaded on the long axis of the motor. Each group of electromagnetic coils is electrically connected to the motor. , The electric spray gun is installed on the reciprocating device, and the reciprocating device is installed on the drum-shaped end cover. It prints accurately and clearly, and can realize online automatic operation.
Description
technical field [0001] The invention relates to the technique of jet printing standard characters and symbols on the surface of metal pipes in the metallurgical industry, in particular to a rotary drum jet printing machine. Background technique [0002] At present, most of the inkjet printing equipment for printing standard characters or symbols on the surface of metal pipes are dot matrix CNC machines imported from Denmark, Japan, Germany and other countries. A difficult point in domestic and foreign spraying labels that has not been resolved for many years. The other is direct spraying with frame-type stencils, which can display fonts well, but due to the manual operation of slack-stencil change and layout, there are many errors, which cannot meet the spraying requirements, and cannot automatically work online, which is different from the current large-scale industrial assembly line. production matching. Contents of the invention [0003] In order to overcome the above...
