Uninterrupted feeding auxiliary device of printing machine, and bearing plate and working principle thereof

Abstract

The invention discloses an uninterrupted feeding auxiliary device of a printing machine, and a bearing plate and a working method thereof. The device comprises a stand (1), a bracket mechanism (2), a bracket lifting driving device (3), a main bracket expansion and retraction driving device (4) and a secondary bracket expansion and retraction driving device (5), wherein the bracket mechanism comprises a bracket base (21), a main bracket (22) and a secondary bracket (23); the bearing plate (6) of the device is matched with the device for use and is fixed on the conventional feeder; and the bearing plate (6) is provided with a bearing plate groove (61) and a bearing beam (62) at interval. Due to the adoption of the structure of the main / secondary bracket (22 / 23), a main bearing sheet (223) can bear heavy plates for lamination; the thickness of a secondary bearing sheet (233) is less than an effective material taking height range of the printing machine, so that the effective material taking of the printing machine is not influenced even if plates are lowered due to extraction; and the main / secondary bracket (22 / 23) is driven by the driving device to finish cyclic actions of bearing, feeding, replenishing, returning and bearing, so that uninterrupted feeding is realized, and the working efficiency of the printing machine is improved.

Description

technical field [0001] The invention relates to a feeding device and a working method thereof, in particular to a feeding device and a working method of a printing plate for a printing machine. Background technique [0002] At present, the commonly used printing machine feeding device is a device that can be lifted vertically. Its function is to raise the plate to be printed to the height that the printing machine’s suction cup can absorb. After sheeting, the printing machine must be shut down, and the printing machine cannot be started until the feeding device is filled with a stack of plates again. The printing machine is always in an intermittent working state, and the work efficiency is low, which brings the printing machine's capacity loss; the reason for this inefficiency is that when the printing machine is picking up material, the upper surface of the printing plate must be within the effective height range of material picking, which is generally about 10mm; and the ...

[0002] At present, the commonly used printing machine feeding device is a device that can be lifted vertically. Its function is to raise the plate to be printed to the height that the printing machine’s suction cup can absorb. After sheeting, the printing machine must be shut down, and the printing machine cannot be started until the feeding device is filled with a stack of plates again. The printing machine is always in an intermittent working state, and the work efficiency is low, which brings the printing machine's capacity loss; the reason for this inefficiency is that when the printing machine is picking up material, the upper surface of the printing plate must be within the effective height range of material picking, which is generally about 10mm; and the existing equipment cannot be uninterrupted When feeding, ensure that the upper surface of the printing plate is always within the effective height range of the printing machine when the new material is added.
