Description

Technical Field

[0001] The utility model relates to the field of use and maintenance of printing machines, in particular to a printing roller cleaning device. Background Art

[0002] The printing press cylinder is the core component of the printing machinery. The material varies according to different needs. The dirt residue on the surface of the cylinder will not only lead to the decline of the quality of printed products, but also cause machine failure and damage, and increase the maintenance cost of other components. Therefore, it is very important to clean the printing cylinder regularly. The more common method is manual cleaning. Without disassembling the cylinder, use the gap between the components and dip a specific cloth in cleaning liquid to clean it. There are also some methods to disassemble the cylinder and use a cleaning machine to clean it.

[0003] The disassembly and cleaning method requires very professional staff to complete, and the changes to the printing machine itself are relatively large. If the position difference after disassembly and installation is caused, it may also cause greater problems for the printing machine. The manual cleaning method usually requires one hand to wipe and the other hand to turn, but often because the gap is too small or the turning requires a lot of strength to complete, it is impossible to coordinate properly and quickly complete the work. In addition, cleaning a roller requires multiple steps such as wetting, wiping, and drying. Each process requires multiple rotation angles. If there are many printing machines that need maintenance, this method is also very physically demanding.

[0004] Some foreign matter floating on the surface of the drum is usually blown away first. Artificial blowing can only be done for a short time, so a more suitable alternative should be found. Utility Model Content

[0005] The technical problem to be solved by the utility model is that cleaning the cylinder of a printing press without disassembling the cylinder is inefficient, difficult, and labor-intensive, and the labor cost is high, and manual air blowing cannot be performed for a long time.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a printing roller cleaning device, including a small compressed gas tank and a rag, the rag is located under the small compressed gas tank, and also includes a support platform, a height adjustment rod, a mover, an auxiliary structure and a support structure, the height adjustment rod is fixed on the support platform, the height adjustment rod is provided with two groups, the height adjustment rod is used to adjust the height, the mover is fixed on the two groups of height adjustment rods, the auxiliary structure is fixed on the mover, the support structure is fixed on the auxiliary structure, the small compressed gas tank and the rag are installed on the support structure, the mover includes an installation box, an electric component and a limit component, the installation box is fixed on the height adjustment rod, the electric component is arranged on the installation box, and the limit component is fixed on the installation box.

[0007] Furthermore, the electric component includes a motor, a screw and a nut, the motor is fixed on the inner wall of the installation box, the screw is rotatably arranged on the installation box and fixedly arranged on the output shaft of the motor, and the nut is threadedly connected to the screw.

[0008] Furthermore, the motor is a forward and reverse rotating motor.

[0009] Furthermore, the installation box is provided with a moving opening, the limiting assembly includes a limiting rod and a limiting seat, the limiting rod is fixedly arranged on the installation box, and the limiting seat is slidably sleeved on the limiting rod and connected to the nut.

[0010] Furthermore, the auxiliary structure includes a positioning seat, a sliding rod, a sliding seat and a sliding frame. The positioning seat is fixed on the installation box. The positioning seat is provided with two groups. The sliding rod is fixed on the two groups of positioning seats. The sliding seat is slidably sleeved on the sliding rod. The sliding frame is fixed on the nut and slides through the moving port. The sliding frame is fixedly connected to the sliding seat.

[0011] Furthermore, the supporting structure includes a first pushing rod, an inclined fixed seat, a supporting frame, a second pushing rod and a supporting frame, the first pushing rod is installed on the sliding frame, the inclined fixed seat is fixed on the output rod of the first pushing rod, the supporting frame is fixed on the inclined fixed seat, the small compressed gas tank is installed on the inclined fixed seat, the second pushing rod is penetrated on the supporting frame, the supporting frame is fixed on the output rod of the second pushing rod, and the rag is bonded to the supporting frame.

[0012] Furthermore, a placement frame is provided on the support platform.

[0013] Preferably, an extension pipe of appropriate length is installed for the compressed air tank according to the actual location and situation.

[0014] The beneficial effects achieved by the utility model using the above structure are as follows:

[0015] 1. Use a small compressed gas tank to replace manual labor to clean the surface of the printing cylinder when necessary. This is the simplest way.

[0016] 2. Use movers to replace manual movement. Manual movement only requires rotating the printing press cylinder according to the rhythm, which can improve work efficiency and reduce work difficulty. BRIEF DESCRIPTION OF THE DRAWINGS
