A special offset printing machine for bottle caps

Abstract

The invention relates to the field of offset presses, in particular to an offset press special for a bottle cap. The offset press special for the bottle cap comprises an overturning mechanism, a collecting mechanism, heating plates, a machine body, two driving mechanisms and a power supply communicating mechanism. The heating plates fixed to one end of an electric push rod are connected to the interior of a collecting hopper in a relatively sliding manner. By means of the electric push rod, uniform heating of the bottle cap inside the collecting hopper is realized, and scratches of handwritingand icons on the bottle cap are avoided. While the electric push rod moves, a pushing column makes contact with a butting ring, so that electrical connection between a copper sheet and a copper column can be realized, a motor is powered on to stir the bottle cap inside the collecting hopper, and the bottle cap is prevented from blocking a discharging pipe. A fan blade with an arc-shaped structureat one end can prevent the bottle cap from being scratched. Therefore, the bottle cap can be heated by the heating plates and be turned over. Through the contraction of the electric push rod, the copper sheet and the copper column can be powered off, and the heating plates can move oppositely to prevent the bottle cap from being over baked.

Description

technical field [0001] The invention relates to the field of offset printing machines, in particular to a special offset printing machine for bottle caps. Background technique [0002] Bottle caps are used to seal bottles. According to different functions, there are bottle caps of different shapes and different operation methods. The caps of soda cans are ring-shaped for pulling, and the caps of canned meat have no fixed shape. The cap of the injection bottle is made of glass. It needs to be polished with a grinding wheel and then popped open. The bottle cap offset printing machine is a machine for printing plastic bottle caps, which can print signs, characters, etc. [0003] However, the traditional offset printing machine for bottle caps directly collects the bottle caps after printing and then packs them. The ink on the surface of the newly printed bottle caps is not easy to dry, and the collision between the bottle caps is easy to scratch the newly printed logos and char...

Problems solved by technology

[0003] However, the traditional offset printing machine for bottle caps directly collects the bottle caps after printing and then packs them. The ink on the surface of the newly printed bottle caps is not easy to dry, and the collision between the bottle caps is easy to scratch the newly printed logos and characters during collection. Injury, it is easy to block the collection bucket during the collection process, affecting the production progress
