Description

Cleaning device for printing plate cylinder of printing machine

Technical Field

The utility model relates to a printing machine is cleaning device for forme cylinder belongs to lithography apparatus technical field.

Background

One of the features of flexographic printing machines is that they can print images and text of different longitudinal lengths, and therefore, flexographic printing machines are generally equipped with a set of plate cylinders corresponding to the specifications of the commonly used printing elements. The forme cylinder comprises a cylinder body and a supporting shaft, wherein the two ends of the cylinder body are respectively provided with a boss-shaped roller pillow, the supporting shaft is connected with the ink tank bracket through a bearing sleeved in the roller pillow during installation, the outer side of the roller pillow is connected with the bearing in a sealing manner through an oil seal, lubricating oil needs to be injected into the roller pillow for protection of a corresponding connecting structure, and after long-time work is carried out, the oil seal is easy to deform or age, so that oil leakage is caused. However, because the plate cylinder has more specifications and higher replacement and maintenance costs, the plate cylinder is mostly continuously used when slight oil leakage occurs.

The impression cylinder rotates at plate cylinder downside, and after the oil seepage took place for plate cylinder, long-time use corrodes the impression cylinder easily and leads to its surface to cave in, makes the colour overprinting inaccurate during printing, directly influences the good or bad of printed matter. In addition, a lot of paper dust is generated in the printing process, and the paper dust is easy to adhere to a roll pillow with oil stains to pollute a roller.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a cleaning device for a plate cylinder of a printing press, which can overcome the disadvantages of the prior art.

The utility model aims at realizing through the following technical scheme:

a cleaning device for a printing plate cylinder of a printing machine comprises cleaning mechanisms which are arranged at two ends of the printing plate cylinder and are abutted against roller pillows, wherein the cleaning mechanisms are fixedly connected to an ink tank support through a fixing frame.

The cleaning mechanism comprises a cleaning body capable of absorbing oil.

The cleaning body is a cleaning sponge or a brush.

The bottom of the cleaning body is provided with an oil receiving box, and the oil filling box is connected with an oil receiving bag body through an oil outlet pipe.

The oil receiving box is a plastic box body sleeved at the bottom of the cleaning body and is connected with the fixed frame through a connecting sheet.

The oil receiving bag body is a soft bag body and is hung on the fixing frame through a pull rope.

The aforesaid mount is L shape fixed block, and the long limit of L shape fixed block links firmly on the china ink groove support through the bolt, and the minor face extends to the roller pillow side to the cleaning body can be dismantled with the minor face and be connected.

Compared with the prior art, the utility model discloses a printing machine is cleaning device for forme cylinder, its including set up at forme cylinder both ends and with roller pillow looks butt's clean mechanism, clean mechanism links firmly on china ink groove support through the mount. The cleaning mechanism is additionally arranged outside the roller pillows at the two ends of the printing plate cylinder and is abutted against the roller pillows, the roller pillows rotate along with the roller pillows in the rotating and running process of the printing plate cylinder, the cleaning mechanism can realize the cleaning of the roller pillows, and the technical problems that the roller pillows are adhered with oil stains, paper scraps, dust and the like due to oil leakage of the oil seal at the side ends of the roller pillows in the prior art are effectively solved; in addition, the cleaning mechanism is a cleaning body capable of absorbing oil, so that oil stains can be absorbed, the printing roller is prevented from falling and corroding, and meanwhile, an oil receiving structure is additionally arranged at the bottom of the cleaning body, so that the oil stains absorbed by the cleaning body can be discharged into the oil receiving structure, and the oil stains can be further prevented from falling.

The utility model has the advantages that:

the utility model discloses simple structure, easy dismounting is swift, can effectively solve the forme cylinder both ends oil impregnate problem, and need not drop into a large amount of manpowers and cost and carry out the forme cylinder maintenance.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.
