Guide flattening mechanism for corrugated paper

Abstract

The invention provides a guide flattening mechanism for corrugated paper. The guide flattening mechanism comprises multiple lead screws; each lead screw comprises a right-hand lead screw part with a forward thread and a left-hand lead screw part with a reverse thread, right-hand lead screw nuts are arranged on the right-hand lead screw parts, left-hand lead screw nuts are arranged on the left-handlead screw parts, guide seats are fixedly arranged on the left-hand lead screw nuts and the reverse-tooth lead screw nuts, and sliding blocks are arranged on the guide seats; all the lead screws aredriven by a driving mechanism to rotate synchronously; a guide rail is arranged beside each lead screw, and the guide seats are slidably clamped on the corresponding guide rails through the sliding blocks; and the guide flattening device further comprises two pressing strips which are arranged under the right-hand lead screw nuts and the left-hand lead screw nut and extends along in conveying direction of the corrugated paper, the guide seats on all the right-hand screw nuts are connected to the same pressing strip through guide columns capable of sliding up and down, and the guide seats on all the left-hand lead screw nuts are connected to the other pressing strip through the guide columns capable of sliding up and down. According to the guide flattening mechanism, a carton box digital ink-jet printer can effectively prevent the phenomenon of paper jam and spray head scratch are effectively prevented, the rejection rate is reduced, and the stability of the carton digital ink-jet printer is improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a guiding flattening mechanism for corrugated paper. Background technique [0002] Carton digital inkjet printing machine (hereinafter referred to as: inkjet machine) is a relatively advanced printing technology at present. Different from the traditional ones: offset printing, embossing, and flexo printing, which can print out colorful and three-dimensional patterns, which are used in the digital carton printing industry. Carton digital inkjet printing needs to print patterns on flat cardboard, but due to the long-term storage of paper in the warehouse and the influence of unfavorable factors such as during transportation and environmental temperature expansion and contraction, there are usually different degrees of arching and flatness. The degree varies. Uneven paper entering the inkjet machine can easily cause paper jams and scratches on the nozzle. The nozzle is ...

Problems solved by technology

However, this method is only limited to relatively flat cardboard, and the adsorption effect is not ideal for cardboard with bulging in the middle and uneven flatness, and it is still easy to cause paper jams and scratches on the nozzle.

At the same time, frequent downtime due to paper jams will affect production efficiency
