Embodiment Construction

[0029] The present invention will be further described below in conjunction with the embodiments and accompanying drawings (1 to 3).

[0030] The flatbed flexographic direct plate-making machine involved in the present invention includes a base platform 1, a first driving system 2, an exposure platform 3, a second driving system 6, an imaging head and a control system (not shown). The straight line where the flexographic printing direction is located is defined as the X-axis, and the line perpendicular to the X-axis is the Y-axis.

[0031] The first driving system 2 is located on the surface of the base 1, the first driving system 2 includes a first moving frame 21, a first driving device 245 is connected to the first moving frame 21, and the first driving The device 245 includes a motor for controlling the linear movement of the first moving frame 21 along the X-axis direction. A slide block 26 is fixedly installed below the first moving frame 21 , and the slide block 26 is ...

Abstract

The invention discloses a platform type flexible plate computer-to-plate (CTP) machine which comprises a base platform, a first drive system, an exposure platform, a second drive system, an imaging head and a control system. The first drive system is located on the base platform and moves along the X axis relative to the base platform. The exposure platform is of a hollow structure and is fixedly connected with the first drive system. An air suction device communicates with the exposure platform. The second drive system is located on the base platform and moves along the Y axis relative to the base platform. The imaging head is fixedly connected with the second drive system and located over the exposure platform. The control system is electrically connected with the first drive system, the second drive system and the imaging head. Compared with a roller type flexible plate CTP machine, the platform type flexible plate CTP machine is simpler, few in element, convenient to repair and maintain, more intuitive in plate feed mode compared with the roller type flexible plate CTP machine, few in plate feed step and low in requirement.

Description

technical field [0001] The invention relates to the field of printing plate making, in particular to a platform type flexographic direct plate making machine. Background technique [0002] Existing flexible plate-making is external drum imaging, which requires the plate to be mounted outside the cylindrical drum, and the laser beam is perpendicular to the axis of the cylindrical drum to expose and image the plate. During imaging, the cylinder rotates, and the imaging head sweeps the cylinder in a linear motion. In order to improve efficiency, the technology of multi-channel laser beam array imaging is generally adopted. There are usually two ways, one is that the scanning head moves forward by the width of a majority of the track after the laser beam scans the image along its respective track; the other is a spiral way, and the scanning head moves along the axis of the drum while the drum is rolling. direction forward. The pages scanned by the latter method are prone to s...
