Abstract
Description
Technical Field
[0001] This utility model relates to the fields of textile and label printing technology, and in particular to a wear-resistant protection device for the printing bottom roller of a rotary printing machine and the rotary printing machine itself. Background Technology
[0002] Currently, rotary printing presses consist of one or more printing presses, each capable of using a single dye to print labels in multiple colors simultaneously. When some printing presses are in operation, the printing rollers on the non-operating presses must be removed. During production, the printing rollers on the non-operating presses do not rotate. As the printing roll travels through the press, it wears down the surface of the printing rollers on the non-operating presses. Severe wear can render those presses unable to operate normally. Utility Model Content
[0003] Therefore, it is necessary to provide a wear protection device for the printing bottom rollers of a rotary printing press. This utility model's wear protection device for the printing bottom rollers of a rotary printing press can automatically isolate the printing roll from the printing bottom rollers on the non-operating printing press stand, preventing wear on the surface of these printing bottom rollers and effectively protecting the printing bottom rollers on the non-operating printing press stand.
[0004] One embodiment of this application provides a wear protection device for the printing bottom roller of a rotary printing press.
[0005] A wear-resistant protection device for the printing bottom roller of a rotary printing press includes a fixed frame, a moving mechanism, a protective plate, and a detection mechanism. The fixed frame is mounted on the frame of the rotary printing press. The moving mechanism is mounted on the fixed frame, and the protective plate is connected to the moving mechanism. The moving mechanism drives the protective plate to move. The detection mechanism is mounted on the frame of the rotary printing press and is used to detect whether there is a printing roller on the printing press base of the rotary printing press. When the detection mechanism detects that there is no printing roller on the printing press base of the rotary printing press, the moving mechanism can drive the protective plate to move to a position between the printing roll and the printing bottom roller of the rotary printing press. When the detection mechanism detects that there is a printing roller on the printing press base of the rotary printing press, the moving mechanism can drive the protective plate to move away from the position between the printing roll and the printing bottom roller of the rotary printing press.
[0006] In some embodiments, the moving mechanism includes a first driving component and a second driving component. The first driving component is mounted on the fixed frame, the second driving component is connected to the first driving component, and the protective plate is connected to the second driving component. The first driving component is used to drive the second driving component and the protective plate to move along a first direction, and the second driving component is used to drive the protective plate to move along a second direction.
[0007] In some embodiments, one of the first direction and the second direction is a horizontal direction and the other is a vertical direction.
[0008] In some embodiments, the first drive component is a telescopic cylinder.
[0009] In some embodiments, the second drive component is a telescopic cylinder.
[0010] In some embodiments, the protective plate is mounted horizontally.
[0011] In some embodiments, the thickness of the protective plate is 1mm to 5mm.
[0012] In some embodiments, the length of the protective plate is not less than the length of the printing roller, and the width of the protective plate is not less than the diameter of the printing roller.
[0013] In some embodiments, the detection mechanism is mounted on the frame of a rotary printing press at a height corresponding to the printing roller.
[0014] In some embodiments, the detection mechanism includes a photoelectric sensor.
[0015] An embodiment of this application also provides a rotary printing press.
[0016] A rotary printing press includes the anti-wear protection device for the printing bottom roller of the rotary printing press as described in any of the above embodiments.
[0017] The aforementioned anti-wear protection device for the printing bottom rollers of a rotary printing press can automatically isolate the printing roll from the printing press base when it is not in operation, preventing wear on the surface of these printing bottom rollers and effectively protecting the printing bottom rollers on the printing press base when they are not in operation. Specifically, during use, the anti-wear protection device for the printing bottom rollers of the rotary printing press of this application controls the detection mechanism to detect whether there is a printing roller on the printing press base of the rotary printing press. When the detection mechanism detects that there is no printing roller on the printing press base of the rotary printing press, the moving mechanism can drive the protective plate to move to the position between the printing roll and the printing bottom roller of the rotary printing press. The protective plate isolates the printing bottom roller, preventing sliding friction between the printing roll and the printing bottom roller. When the operator installs the printing roller into the printing press base of the rotary printing press, the detection mechanism detects that there is a printing roller on the printing press base of the rotary printing press, and the detection mechanism will generate a signal. The moving mechanism can then drive the protective plate to move away from the position between the printing roll and the printing bottom roller of the rotary printing press, allowing the printing bottom roller to work normally in conjunction with the printing roller.
