Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and in particular relates to a spray humidification and static electricity removal mechanism for a flexographic printing machine. Background Technology

[0002] Due to defects in the papermaking process, the surface of the roll paper used in flexographic printing presses carries static electricity, resulting in low printing speed, uneven paper collection, and subsequent production processes being unable to proceed normally, as well as significant waste.

[0003] The common solutions in the industry are: 1. Installing anti-static bars on flexographic printing machines. However, because there are gaps in the anti-static needles of the bars, static electricity cannot be completely eliminated, and it still affects subsequent processes. 2. Placing rolls of paper in a humid environment (humidity above 80%) for more than 15 days to allow the paper to fully absorb water and eliminate static electricity. Because the placement time is relatively long, it seriously affects product delivery time. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a spray humidification and anti-static mechanism for flexographic printing machines that utilizes the principle that paper can eliminate static electricity when it is in a moisture-absorbing state.

[0005] The purpose of this utility model is achieved through the following technical solution: This flexographic printing machine spray humidification and antistatic mechanism includes a paper feeder; one end of the paper feeder is provided with a support frame for holding the roll paper, and the other end of the paper feeder is provided with a humidification component for humidifying the paper. The humidification component and the support frame are provided with a rolling roller unit for paper rolling. The humidification component is located at the upper end of the paper feeder, and the paper inlet of the humidification component is flush with the upper end surface of the rolling roller unit. The humidification component is connected to a booster water pump through a water pipe. The booster water pump is installed on a water tank, and both the booster water pump and the water tank are located below the humidification component.

[0006] The beneficial effects of this utility model are as follows: Compared with the prior art, by adding a humidification component to the paper feeding machine, the paper is continuously and dynamically humidified during the printing process, eliminating static electricity, ensuring smooth production in subsequent processes, and eliminating paper waste caused by static electricity.

[0007] Preferably, the humidification component includes a base and a top cover. The base is fixed on the paper feeder, and the top cover is located above the base and fixed on the paper feeder via a bracket. A paper insertion opening is provided between the base and the top cover for paper to pass through. Both the base and the top cover are equipped with spray pipes, and the spray pipes are connected to the water pipe. Through the above structure, the humidification component forms a relatively sealed space, and the relative humidity of the sealed space is maintained at 70%-80%, so that the paper is in a state of absorbing water and becoming damp.

[0008] Preferably, the spray pipe has four pipes, with two spray pipes installed inside the base and the top cover, and the upper and lower spray pipes are distributed in a corresponding manner. The spray nozzles of the spray pipes are distributed in a corresponding manner and face the upper and lower surfaces of the paper. Through the above structure, the surface of the paper absorbs water and becomes damp more uniformly.

[0009] Preferably, all water pipes connected to the spray pipe are connected in parallel by a main water pipe, and the main water pipe is connected to the booster pump; this ensures that the water pressure of the spray pipes is consistent, thereby making the water absorption and moisture absorption on the paper surface more uniform.

[0010] Preferably, both the water pipe and the main water pipe are located on one side of the paper feeder, and the water pipe and the spray pipe are connected and fixed to each other via a movable threaded interface; this makes it easier to assemble and disassemble the water pipe and the spray pipe, while the water pipe and the main water pipe also provide support for the top cover.

[0011] Preferably, the bottom of the base is provided with a drain outlet, which is connected to the water tank through a drain pipe; this allows the water accumulated in the base to be drained in a timely manner, and also achieves the effect of energy saving.

[0012] Preferably, the rolling roller unit includes three rolling rollers, two of which are located at the upper part of the paper feeder and are flush with the paper feed opening, and the other rolling roller is located at the lower part of the paper feeder and is triangularly distributed with the two rolling rollers; this makes the paper tension better during the rolling process.
