Description

Composite printing roller surface cleaning mechanism

[0001] The present invention relates to a roller cleaning mechanism, particularly a composite printing roller surface cleaning mechanism that combines a wheel brush and a water mist nozzle to remove stickies attached to the surface of the roller wheel.

[0002] In many industrial fields, roller assemblies are often used. The surface of the roller is often attached to various stickies during the operation procedure. For example, for the printing roller used in the printing industry, it is often in the printing process that stickies (such as various printing pigments, rubber materials, dust, fine materials, etc.) adhere to the surface of the roller. , And affect the quality of printing. [0003] In order to remove the sticky matter adhering to the wheel surface of the roller, there is a device in the prior art that uses a wheel brush to brush off the sticky matter on the wheel surface. However, the cleaning effect is not ideal if the wheel brush is used as the cleaning method of the roller. Especially for the removal of the sticky matter adhering to the wheel surface, the effect is often not good. Moreover, after a period of use, the brush often comes off and wears off, and the wheel brush must be replaced frequently, which increases the cost. [0004] In another conventional technology, there is a device that uses a high-pressure nozzle structure, and uses the fine holes of the high-pressure nozzle as the air jet flow channel to spray the sticky matter on the wheel surface. However, because the printing roller is easy to stick to the printing oil due to long-term use, simply using the high-pressure nozzle as the roller cleaning method cannot effectively remove the viscous oil on the printing roller.

[0005] For this reason, the main purpose of the present invention is to provide a composite printing roller surface cleaning mechanism, which uses a wheel brush and a water mist nozzle to simultaneously clean the surface of the roller wheel with high efficiency. [0006] The technical means used in the present invention includes a wheel brush arranged at a position corresponding to a roller, and driven by a wheel brush motor to rotate; A distance from the wheel surface. The wheel brush and the water mist nozzle are supported on a supporting seat. A lifting mechanism can drive the seat to a lowered position or a raised position. Wherein, when the bearing seat is in the raised 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 mist sprayed to the wheel surface of the roller to remove the adhesion on the wheel surface. The sticky substance on the wheel surface. [0007] Preferably, the present invention further includes a horizontal displacement mechanism connected to the socket to drive the socket to move along the axial direction of a roller parallel to the roller, thereby driving the wheel brush and the water The mist nozzle is displaced in the axial direction of the roller. [0008] Preferably, the horizontal displacement mechanism includes a guide rail configured to correspond to the roller in the axial direction of the roller; a displacement drive unit provided on one side end of the guide rail; and a guide wheel provided on the guide rail The other side end corresponds to the displacement drive unit; a belt is combined with the guide rail and is located between the displacement drive unit and the guide wheel; and a displacement seat is combined with the bearing seat and the belt. The displacement driving unit drives the displacement seat to move along the roller axial direction through the belt, thereby driving the bearing seat to move along the roller axial direction. [0009] Preferably, the present invention further includes an air suction and dust collection device having a suction hood, a high-pressure dust collection device, and a suction pipe connecting the suction hood and the high-pressure dust collection device. The cover system at least partially covers the wheel brush, so that the sticky matter removed by the wheel brush is sucked and sent to the high-pressure dust collection device through the suction pipe. [0010] Preferably, the present invention further includes a wheel brush fine-tuning mechanism, which includes a connecting plate, one end of the connecting plate is connected to a shaft column of the bearing, and the wheel brush is connected to the other end of the connecting plate , The connecting plate is deflected with the shaft column as the center of rotation by an applied force, so as to fine-tune the wheel brush corresponding to the wheel surface of the roller in an upward fine-tuning position or a downward fine-tuning position. [0011] Preferably, the water mist nozzle is connected to an air pipeline and a water supply pipeline. [0012] In another embodiment of the present invention, the composite printing roller surface cleaning mechanism includes a wheel brush, which is arranged at a position corresponding to the wheel surface of the roller, and is rotated by a wheel brush motor; a water mist nozzle, It is arranged at a position facing the wheel surface of the roller and a distance from the wheel surface; a bearing seat for holding the wheel brush and the water mist nozzle; a horizontal displacement mechanism connected to the bearing seat with To drive the bearing seat to move along a roller axial direction parallel to the roller, so as to drive the wheel brush and the water mist nozzle to move in the roller axial direction. Wherein, when the brush surface of the wheel brush contacts the wheel surface of the wheel 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 to the wheel surface of the wheel to remove the adhesion on the wheel surface. The sticky matter on the wheel surface. [0013] In terms of effects, the present invention uses the rotating brush of the wheel brush and the high-pressure micro-mist of the water mist nozzle to simultaneously remove the adherents attached to the wheel surface to achieve a high-efficiency composite cleaning effect. [0014] When the wheel brush rotates to remove the sticky matter attached to the wheel surface of the roller, the water mist nozzle performs high-pressure micro-mist spraying, which helps the dissociation and spraying of the sticky matter, and achieves a composite cleaning The high-pressure micro-mist also helps provide necessary wetting and friction relief between the brush bristles and the contact roller surface. [0015] According to this, the present invention can effectively overcome the problems that the conventional single wheel brush mechanism cannot effectively clean the roller, the brush is easy to fall off and wear, and the wheel brush must be replaced frequently. The roller achieves problems such as poor cleaning efficiency and easy blockage of the jet flow channel. [0016] When the present invention is used in the cleaning of the printing roller, it is particularly effective for the removal of various stickies (such as printing pigments, glue, dust, fine materials, etc.) attached to the surface of the printing roller. [0017] The specific technology adopted in the present invention will be further explained by the following embodiments and accompanying drawings.

[0026] Referring to FIGS. 5 and 6, when the lifting drive unit 51 is not actuated, the socket 4 is in a lowered position P1 (as shown in FIG. 5), and the wheel brush 2 does not touch the wheel surface 1 of the roller 1 at this time. . When the lifting driving unit 51 is activated, the ejector bearing 4 is driven to a raised position P2 (as shown in FIG. 6) through the driving rod 52, so that the brush surface of the wheel brush 2 contacts the wheel surface 1 of the roller 1. At this time, when the wheel brush 2 is driven to rotate by the wheel brush motor 22, and in conjunction with the rotation of the roller 1, the sticky matter on the wheel surface 11 of the roller 1 can be brushed off. [0027] At the same time, the water mist nozzle 3 generates a high-pressure micro mist sprayed to the wheel surface 11 of the roller 1 to clean the wheel surface 11 of the roller 1, so that the surface 11 of the roller 1 can be combined.
