Embodiment 1

[0048] One of the implementations of the clutch device of a digitally controlled automatic ink feeding of a printing press of the present invention, such as figure 1 , figure 2 Indicates that it includes an electromagnetic clutch and a controller 15 that automatically controls the clutch of the electromagnetic clutch; the electromagnetic clutch includes an electromagnet 3 and an armature assembly 4; the stator of the electromagnet 3 is fixedly installed on the transmission side frame 6 of the printing machine, and the electromagnet The rotor 3 is fixedly connected to the ink roller shaft 7 of the printing press; the armature assembly 4 is connected to the driving wheel 10 of the printing press, and the driving wheel 10 is sleeved on the ink roller shaft 7 through the first bearing 5; the controller 15 and the electromagnet 3 The yoke coil 9 is electrically connected.

[0049] Thus, through the clutch device of a digitally controlled automatic ink delivery of a printing machi...

Embodiment 2

[0054] One of the embodiments of the clutch device of the digitally controlled automatic ink feeding of the printing machine of the present invention, such as figure 1 , figure 2 As shown, the main technical solution of this embodiment 2 is basically the same as that of embodiment 1, and the features not explained in this embodiment 2 are explained in embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the connecting piece is set as a connecting flange.

[0055] Specifically, the connector is set as a shaft sleeve 8, one end of the shaft sleeve 8 is connected with a coupling flange, the armature assembly 4 is fixedly connected to the coupling flange, and the driving wheel 10 is fixedly connected to the other end of the shaft sleeve 8 away from the coupling flange.

[0056] Specifically, the connector is set as a shaft sleeve 8, one end of the shaft sleeve 8 is provided with an integrally formed coupling flange, the arm...

Embodiment 3

[0058] One of the embodiments of the clutch device of the digitally controlled automatic ink feeding of the printing machine of the present invention, such as figure 1 , figure 2 As shown, the main technical solution of this embodiment 3 is basically the same as that of embodiment 2, and the features not explained in this embodiment 3 are explained in embodiment 2, and will not be repeated here. The difference between this embodiment and Embodiment 2 is that: the second bearing 12 is arranged between the shaft sleeve 8 at its connecting flange and the ink roller shaft 7, and the shaft sleeve 8 is sleeved on the ink roller shaft 7 through the second bearing 12; Alternatively, a second bearing 12 is provided between the coupling flange connected to the shaft sleeve 8 and the ink roller shaft 7 , and the coupling flange is sleeved on the ink roller shaft 7 through the second bearing 12 . By arranging the second bearing 12, the coupling flange can be kept in balance when transpo...

Abstract

A clutch device for numerically-controlled automatic ink conveying of a printing machine comprises an electromagnetic clutch, and a controller for automatically controlling the electromagnetic clutch to clutch, wherein the electromagnetic clutch consists of an electromagnetic device and an armature assembly; a stator of the electromagnetic device is fixedly mounted on a rack section at the transmission side of the printing machine, and a rotor of the electromagnetic device is fixedly connected with an ink roller rotating shaft of the printing machine; the armature assembly is connected to a driving wheel of the printing machine; the driving wheel sleeves the ink roller rotating shaft through a first bearing; and the controller is electrically connected with magnetic yoke coils of the electromagnetic device. According to the device, the driving wheel can be used for driving an outer ring of the first bearing and the armature assembly to rotate, rather than driving the ink roller rotating shaft to rotate, under the condition that the electromagnetic clutch is not electrified; the controller and the electromagnetic clutch are matched to achieve the advantage of short clutching delay time. The device has the characteristics of being safe to operate, simple in structure, high in control accuracy, and low in cost.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a clutch device for digitally controlled automatic ink feeding of a printing machine. Background technique [0002] In the prior art, during the printing process of most ink roller printing machines, the driving wheel drives the ink roller to run continuously, which causes the ink roller to overheat or wear and leak from both ends of the ink roller. In order to prevent the ink from leaking from both ends of the ink roller, some need to set a sealing ring to block the ink from flowing out. However, in the process of non-continuous printing (such as: printing of ice cream cups, disposable thermoformed water cups, etc.), the ink roller is often in the non-ink printing condition, and in this condition, the continuous idling of the ink roller is also It will lead to accelerated aging and embrittlement of the sealing ring due to friction and wear or long-term exposure to hi...
