Description

[Detailed Description of the Invention] This invention relates to a washing and dehydrating tool for water rods, cylindrical, and water rods used in offset printing machines.

Offset printing presses use water rod rollers to supply moisture to the stamp surface.

This roller has a roller body covered with a cylindrical Molton made of fibers that have properties similar to a blanket.

If ink, dirt, or other impurities adhere to the surface of the water rod roller as described above, the water supply effect will be reduced.

For this reason, those who use the offset printing press must constantly perform cleaning operations to remove deposits from the surface of the cylindrical Molton.

Conventionally, cylindrical Molton cleaning involves bringing a cylindrical Molton coated onto the roller body to a washing place, impregnating it with a cleaning liquid and rubbing the surface with a cleaning brush, and then rinsing with water to wash off any deposits.

When the above-mentioned washing operation is performed, the cylindrical Molton absorbs sufficient water, so it takes a long time to dry if it is washed with water.

For this reason, it is necessary to perform the dewatering operation while handling the surface of the cylindrical Molton using a rod-shaped draining tool prepared separately.

As mentioned above, using completely separate tools for cleaning and dewatering the cylindrical Molton is not only inconvenient, but also reduces work efficiency, and requires constant management of the brush and dewatering tool. There is the trouble of having to do so.

This invention was devised in view of the above points, and the purpose is to provide a tool that integrates a cleaning brush and a dewatering tool and can efficiently perform the cleaning and dewatering work of cylindrical mortons.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the cleaning and dehydrating tool is composed of a cleaning brush 1 and a draining doctor blade 2 attached to the brush 1.

The cleaning brush 1 has bristles 4 implanted on the bottom surface of a brush stand 3 formed into an oval shape.The bristles 4 are made of relatively large diameter synthetic resin wire, and each bristle is It is a waved version.

A plurality of the bristles 4 are bundled and fixed to the brush stand 3 by known means to prevent hair pulling.

When the bristles 4 are waved, they become strong and will not bend easily during use, and the ends of the bundled bristles are oriented in various directions, further improving the cleaning effect.

The doctor blade 2 for draining uses a band-shaped metal plate with restoring elasticity, such as a steel plate or a stainless steel plate, and one end thereof is pivotally connected to the end band on the upper surface of the brush stand 3 by a pin 5. It is freely rotatable around 5.

It is preferable that the doctor blade 2 is formed in such a length that it does not protrude from the outer periphery of the brush stand 3, as shown by the solid line in FIG.

The cleaning and dewatering tool of this invention has the above-mentioned structure, and when cleaning the water rod roller A, the doctor blade 2 is stacked and stored on the brush stand 3, as shown by the solid line in FIG. By simply holding the brush stand 3 and rubbing the surface of the cylindrical Molton B with the bristles 4, cleaning with detergent and washing with water can be performed.

The dewatering work after washing is carried out by protruding the doctor blade 2 from the periphery of the brush stand 3, and handling the surface of the cylindrical Molton B with the side edge of this blade 1-2. The side edge and the side edge of the doctor blade 2 may be pressed against the surface of the cylindrical Molton B and handled in the axial direction, and the surface of the cylindrical Molton B can be washed with water and then dehydrated.

As described above, according to this invention, the doctor blade for draining water is rotatably mounted on the brush stand of the cleaning brush, so that it can be attached to the cylindrical moleton of the water rod roller, and cleaning and dewatering can be performed continuously. This makes cleaning the water rod rollers more efficient.

In addition, since the cleaning brush and draining doctor blade are integrated, there is no need to lose the dehydrating tool unlike in the case of separate units, making management easier.

Furthermore, since the doctor blade can be stored on the top surface of the brush stand, it not only does not interfere with the cleaning process, but also allows the brush stand and doctor blade to work simultaneously for dewatering, allowing for effective dehydration work.
