Description

Composite printing roller surface cleaning mechanism

technical field

The present invention relates to a roller cleaning mechanism, in particular to a composite printing roller surface cleaning mechanism which combines a roller brush and a water mist nozzle to remove the sticky substances attached to the roller surface.

Background technique

Roller assemblies are often used in many industrial fields. The wheel surface of the roller is often adhered to various sticky substances during the operation procedure. For example, in the case of printing rollers used in the printing industry, sticky substances (such as various printing pigments, glue, dust, fine materials, etc.) are often adhered to the surface of the roller during the printing process. , which affects the quality of printing.

In order to remove the sticking matter adhering to the wheel surface of the roller, there is a device which uses a wheel brush to remove the sticking matter from the wheel surface in the known art. However, simply using the wheel brush as the cleaning method of the roller is not ideal. Especially for the removal of the sticky substance adhering to the surface of the roller, the effect is often not good. Moreover, after a period of use, the brushes often fall off and wear out, and the wheel brushes must be replaced frequently, which increases the cost.

In another prior art, there is a device using a high-pressure spray head structure, and the fine holes of the high-pressure spray head are used as air jet flow channels to spray the sticky substances on the wheel surface. However, due to the long-term use of the printing roller, it is easy to stick to the printing oil, so simply using the high-pressure nozzle as the roller cleaning method cannot effectively remove the viscous oil on the printing roller.

SUMMARY OF THE INVENTION

Therefore, the main purpose of the present invention is to provide a composite printing roller surface cleaning mechanism, which can simultaneously clean the roller surface with high efficiency with a roller brush and a water mist nozzle.

The wheel brush and the water mist spray head are supported on a bearing seat. A lift mechanism can drive the holder to be in a lowered position or a raised position. Wherein, when the bearing seat is in the rising position, the brush surface of the wheel brush contacts the wheel surface of the roller and is driven to rotate by the wheel brush motor. At the same time, the water mist nozzle generates a high-pressure micro-mist sprayed on the wheel surface of the roller to remove the adhesion on the wheel surface. the sticky substance of the wheel surface.
