A printing non-stop plate changing installation protection device

Abstract

This utility model discloses a printing plate changing installation and protection device that allows for non-stop printing plate changes. The device includes a printing unit with a printing roller. The key feature is that a safety plate is slidably mounted on the frame. During plate changes, the safety plate is pushed below the printing roller; during operation, it is pushed below the foot pedal and concealed. When changing plates, the safety plate can catch falling printing plates to prevent damage, or catch falling tools and protect the suction box. This utility model has a simple structure.

Description

Technical Field

[0001] This invention relates to the field of printing unit technology, specifically to a protective device for printing plate changing without stopping the printing machine. Background Technology

[0002] In cardboard printing, printing plates often need to be replaced or cleaned due to processing different orders or equipment maintenance. However, existing printing technology consists of multiple printing units arranged along the cardboard's travel direction. The impression roller and printing roller are driven by the same gear transmission chain and cannot rotate independently. When replacing, maintaining, or cleaning the printing plates, the entire machine needs to be stopped. When a cardboard printing machine is equipped with multiple printing units, it is necessary to replace or clean some of the printing units. It is desirable for the printing units that do not need to be replaced or cleaned to continue operating.

[0003] When changing or cleaning some of the configured printing units, the printing plate may accidentally fall and damage it. Or some tools may accidentally fall and damage the suction box. Utility Model Content

[0004] The technical problem this utility model aims to solve is the problem that existing printing units have issues such as printing plates falling off and damaging the printing plates, or tools accidentally falling off and damaging the suction box. This utility model provides a printing plate changing installation and protection device that can protect the printing plates from falling and prevent damage, or catch fallen tools and protect the suction box.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0006] A printing plate changing installation protection device without stopping the printing machine includes a printing unit with a printing roller. The device is characterized in that a safety plate is slidably mounted on the frame. When changing plates during machine stop, the safety plate is pushed under the printing roller. During operation, the safety plate is pushed under the foot pedal and hidden.

[0007] In a preferred embodiment of this utility model, the safety plate is slidably mounted on the frame via a slide rail.

[0008] Thanks to the above technical solution, during machine downtime for plate changing, the safety plate is pushed below the printing plate to catch any falling plates and prevent damage, or to catch falling tools and protect the suction box. This invention has a simple structure. Attached Figure Description

[0012] Figure 4 A three-dimensional schematic diagram of a printing unit equipped with a protective device for plate changing without stopping printing. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] See Figures 1 to 4 The figure shows a printing plate changing and installation protection device that does not stop printing. It includes a printing unit 100, which has a printing roller 110, an inking roller (not shown in the figure) and an impression roller (not shown in the figure).

[0015] The feature of this invention is that a safety plate 200 is slidably mounted on the frame 120. When the machine stops for plate changing, the safety plate 200 is pushed below the printing roller 110 to catch falling printing plates, preventing damage, or to catch falling tools, protecting the suction box 300. During operation, the safety plate 200 is pushed below the foot pedal 400 and hidden. To facilitate easy movement of the safety plate 200, it is slidably mounted on the frame 120 via a slide rail.

Claims

1. A printing plate changing and installation protection device that allows printing to continue without stopping, comprising a printing unit, wherein the printing unit has a printing roller, characterized in that, A safety plate is slidably mounted on the frame. When the machine stops to change plates, the safety plate is pushed under the printing roller. During operation, the safety plate is pushed under the foot pedal and hidden.

2. The printing plate changing and installation protection device according to claim 1, characterized in that, The safety plate is slidably mounted on the frame via a slide rail.
