Description

Offset sheet-fed printing machine non-stop paper loading device

technical field

The utility model relates to a non-stop paper loading device for an offset sheet-fed printing machine, which belongs to the technical field of printing equipment.

Background technique

The automatic paper unloader is connected with the program-controlled paper cutter in a line. The operator gently pushes the cut white material to the paper unloader, automatically aligns the paper and stacks it neatly on the prepared footboard. At present, the white material is manually carried, stacked on the footboard, and then transported to the offset printing feeder and manually loaded.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a non-stop paper loading device for offset sheet-fed printing presses.

The purpose of this utility model is achieved through the following technical solutions:

Offset sheet-fed printing machine non-stop paper loading device, characterized by: a pair of parallel guide rails are laid between the discharge port of the paper unloader and the feed port of the offset printing feeder, and there are slidable rollers on the guide rails Unit, the roller unit includes a roller bracket and a roller. The roller is installed on the roller bracket freely. The rollers are parallel to the guide rails, the rollers are at the same level, and the stacking boards are placed on the rollers.

Further, in the non-stop paper feeding device for offset sheet-fed printing presses above, the running surfaces of the rollers are in a concave triangle shape, and correspondingly, the working surfaces of the guide rails are in a convex triangle shape.

Furthermore, in the non-stop paper loading device of the above-mentioned offset sheet-fed printing press, a fulcrum plate is provided extending downwards from the roller support.

Still further, in the non-stop paper feeding device of the offset sheet-fed printing press, there are four roller units, and two roller units are respectively distributed on the left and right guide rails.

The substantive features and progress of the technical solution of the utility model are mainly reflected in:

The utility model has a unique design and a novel structure, which can transfer the paper from the paper unloading machine to the offset printing paper feeder without stopping the machine, avoids stopping the machine for loading the paper feeder, saves time, and eliminates the fatigue of manual handling. It is convenient to use, easy to apply, and is a practical new design.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Fig. 1: the schematic diagram of the front view of the utility model;

Fig. 2: a top view schematic diagram of the utility model.

Detailed ways

As shown in Figure 1 and Figure 2, the non-stop paper loading device of the offset sheet-fed printing machine, a pair of guide rails 3 parallel to each other are laid between the discharge port of the paper unloader and the feed port of the offset printing feeder. 3 is provided with a slidable roller unit 4. The roller unit 4 includes a roller bracket and a roller 1. The roller 1 is mounted on the roller bracket to rotate freely. The running surface of the roller 1 matches the working surface of the guide rail 3. The surface is a concave triangle. Correspondingly, the working surface of the guide rail 3 is a convex triangle. The roller bracket extends downwards with a fulcrum plate, and the roller bracket is fixed with a receiving groove. The moving roller 2, the roller 2 is parallel to the guide rail 3, the roller 2 is in the same horizontal plane, and the stacker board 5 is placed on the roller 2.

Generally, there are four roller units 4, and two roller units are respectively distributed on the left and right guide rails.

In specific application, the white material of the paper unloader is stacked on the stacking board 5, and the white material is pushed towards the feeding port of the offset printing paper feeder through the roller unit 4. The middle position of the offset printing paper feeding machine, after the positioning is accurate, it will be fed to the paper feeding machine.

To sum up, the utility model has a unique design and a novel structure, which can transfer the paper from the unloading machine to the offset printing feeder without stopping the machine, avoiding the shutdown for feeding the paper feeder, saving time and the fatigue of manual handling .

It should be emphasized that: the above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any simple modification, equivalent change and Modifications still belong to the scope of the technical solution of the utility model.
