Description

Technical Field

[0001] The utility model relates to printing equipment, in particular to a movable printing roller device. Background Art

[0002] The anilox roller and the printing plate roller play a vital role in the flexographic printing process. The anilox roller stores ink through the cells on its surface and transfers an appropriate amount of ink to the printing plate roller when it comes into contact with the printing plate roller. The graphic part on the printing plate roller is usually raised. These raised parts will come into contact with the substrate during the printing process and realize the transfer of the graphic through ink.

[0003] In actual operation, flexographic printing presses frequently require adjustments to the positions of the printing plate roller and anilox roller, as different substrates require different printing positions. The current method generally involves measuring and determining the desired position of the printing plate roller in the flexographic printing press, then using locking devices to install the printing plate roller and anilox roller together on the press. However, this method not only requires manual operation and is prone to errors, but also requires reassembly whenever errors occur, resulting in low efficiency. Furthermore, since the anilox roller is typically mounted on the same bracket as the printing plate roller and requires frequent disassembly for cleaning and replacement, it must be completely disassembled for each cleaning, further reducing efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a movable printing roller device, which can adjust the positions of the printing plate roller and the anilox roller according to printing needs without frequent disassembly and assembly, and can also move and disassemble the anilox roller alone.

[0005] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0006] A movable printing roller device comprises a frame, a printing plate roller, an anilox roller, a first rotation drive device capable of driving the printing plate roller to rotate, and a second rotation drive device capable of driving the anilox roller to rotate, characterized in that it also comprises an overall adjustment device, an overall frame, an anilox roller adjustment device and an anilox roller frame, the overall adjustment device is mounted on the frame, the overall frame is movably arranged on the frame back and forth, and the overall frame is transmission-connected to the power output end of the overall adjustment device; the anilox roller adjustment device is mounted on the overall frame, the anilox roller frame is movably arranged on the overall frame back and forth, and the anilox roller frame is transmission-connected to the power output end of the anilox roller adjustment device; the first rotation drive device is mounted on the overall frame, the printing plate roller is rotatably mounted on the overall frame; the second rotation drive device is mounted on the anilox roller frame, and the anilox roller is rotatably mounted on the anilox roller frame.

[0007] When in use, the movable printing roller device can be driven to move the entire frame via an integral adjustment device, depending on the printing position requirements. This allows for unified adjustment of the positions of the printing plate roller and the anilox roller, eliminating the need for frequent disassembly and assembly. When the anilox roller needs to be disassembled, cleaned, or replaced, the anilox roller can be independently mounted on the anilox roller frame. The anilox roller adjustment device allows the anilox roller to be positioned away from the printing plate roller to create space for disassembly and assembly, and then independently disassembled. After reinstallation, the anilox roller position can be adjusted again via the anilox roller adjustment device to re-engage the anilox roller in contact with the printing plate roller, eliminating the need for complete disassembly. This movable printing roller device allows for adjustment of the positions of the printing plate roller and the anilox roller to accommodate various printing needs. It also allows for the anilox roller to be independently moved, disassembled, and cleaned, effectively improving efficiency.

[0009] In a further preferred embodiment, the integral translation mechanism includes a first screw, a first nut, and a third rotation drive device capable of driving the first screw to rotate. The third rotation drive device is mounted on the frame, and the first screw is rotatably mounted on the frame, with the first screw extending in a direction parallel to the direction of extension of the first guide member.

[0013] In a further preferred embodiment, the anilox roller translation mechanism includes a second screw, a second nut, and a fourth rotation drive capable of rotating the second screw. The fourth rotation drive is mounted on the integral frame, and the second screw is rotatably mounted on the integral frame, extending parallel to the direction of extension of the third guide member.
