Description

TECHNICAL FIELD

[0001] The utility model belongs to printing processing technical field, and specifically relates to a direct drive electric ink fountain roller for multi-color machine set. BACKGROUND

[0002] In the process of offset printing, the ink transfer process is generally that the ink fountain roller transfers ink from the ink fountain to the ink transfer roller, and then the ink spreader spreads the ink from the ink transfer roller into a uniform film, which is then transferred to the printing plate by the inking roller. People output ink from the ink fountain to the inking roller through the ink transfer roller. The shortest transfer route of this process is called the ink path. The transfer of ink between ink rollers is completed by the contact and separation of ink layers on adjacent two ink rollers.

[0003] In the process of multi-color printing, in order to ensure the printing overlay accuracy, the driving mode of the ink fountain roller has strict requirements. Although the traditional shaft driving mode can meet the printing requirements to a certain extent, it has a series of problems such as large volume, high cost, large occupation, and inflexibility, which limits its application in modern multi-color printing.

[0006] Through the above technical scheme, the ink fountain roller is driven by the ink fountain roller special motor, the traditional shaft driving mode is changed, the distribution of ink can be accurately controlled by adjusting the rotating speed of the ink roller special motor, different colors of ink can be evenly applied on the printing material, high-quality printing is realized, and the service life of the ink fountain roller after heat conduction and antibacterial and mildew treatment is increased.

[0007] The utility model is further provided with a bolt threadedly connected to the side surface of the bearing sleeve one, and the side surface of the bolt is threadedly connected with the shell of the ink roller special motor.

[0008] Through the technical scheme, the bearing sleeve one can be installed on the shell of the special motor for the grinding roller through the bolt, and the bearing sleeve one can be removed for replacement.

[0009] The utility model further sets up, the side surface of joint piece one is contacted with the output end of special motor for ink roller, the side surface of joint piece two is contacted with first bearing.

[0010] The utility model further sets up, the side surface of the one end of rotating shaft away from special motor for ink roller is connected with second bearing with interference, the outside surface of second bearing is fixedly connected with bearing sleeve two.

[0011] Through the technical scheme, the main function of bearing sleeve two and bearing sleeve one is support, ensure the stability and reliability of rotating shaft in the process of operation, and this support effect helps to reduce the vibration and deviation of rotating shaft, and can protect rotating shaft from damage, when installing, bearing sleeve one and bearing sleeve two can reduce the direct contact area of rotating shaft and external metal, thereby reducing the wear degree of rotating shaft, effectively prolonging the service life of shaft.

[0012] The utility model further sets up, the side surface of rotating shaft is provided with sealing ring, and the side surface of sealing ring is contacted with bearing sleeve two.

[0013] The utility model has the advantages that:

[0014] (1) The use of special motor for ink roller allows for stepless speed adjustment, thereby changing the ink output, which is particularly important for multi-color units. By adjusting the speed of the special motor for ink roller, the ink distribution amount can be accurately controlled, ensuring that different colors of ink can be evenly and accurately applied to the printing material, thereby achieving high-quality printing results. Adjusting the speed of the motor can correspondingly change the speed of the ink roller, thereby controlling the ink output.

[0015] (2) Direct drive method is adopted, which directly drives the ink roller using a motor, replacing the traditional transmission gear and shaft, reducing mechanical failures. This driving method not only improves the manufacturing and installation efficiency of the machine, but also reduces maintenance costs.

[0016] (3) High-precision control is achieved through the use of a servo drive system, ensuring uniform ink supply for the ink roller and avoiding uneven ink marks or missing printing on the printed product. In addition, the fast response characteristics of the servo drive system also help to improve the overall response speed of the printing machine, which is very helpful for quickly changing printing colors or adjusting printing parameters.
