Automatic plate weight-balancing mechanism for computer to plate

Abstract

The invention relates to an automatic plate weight-balancing mechanism for a computer to plate. The automatic plate weight-balancing mechanism comprises a roller and an installation plate, wherein a screw hole is formed in the left end of the roller; a retaining ring is installed at the left end of the screw hole through a fixing bolt; a weight-balancing groove is formed in the middle part of theroller; a weight-balancing body is connected to one side of the weight-balancing groove; a thread hole is formed in the middle part of the weight-balancing body; a distance inductor is connected to the left end of the thread hole; a weight-balancing block is installed in the thread hole; a groove is formed in the left end of the weight-balancing block; a cylinder is installed at the middle part ofthe installation plate; the right end of the cylinder is connected to an adjustment rod; a bulged strip is arranged at the right end of the adjustment rod; and a controller is installed on the upperpart of the installation plate. According to the automatic plate weight-balancing mechanism disclosed by the invention, through the arrangement for the adjustment rod and the weight-balancing block, the controller receives the information of the inductor, a front drive force is provided by the cylinder part, and the bulged strip and the groove cooperatively rotate for adjusting the position of theweight-balancing block, so as to realize automatic weight-balancing; and the automatic plate weight-balancing mechanism is simple in structure and labor-saving.

Description

technical field [0001] The invention relates to a plate automatic counterweight mechanism for a direct plate-making machine, which belongs to the field of automatic counterweight mechanisms. Background technique [0002] Direct plate-making machine (CTP) is a device for direct plate-making by computer. It is a product of the development of computer typesetting to a certain stage. According to the model of the printing machine and the requirements of the folding pages, the pages are assembled into a large version, and the equipment that directly forms images on the printing plate after passing through the RIP, because it eliminates the traditional printing processes such as film and development, has quickly become popular in the printing industry. [0003] The counterweight adjustment mechanism of plate-to-plate (CTP) is an important technical structure in the field of plate-making. It can solve the dynamic balance problem of the drum in high-speed operation when the same pla...

Problems solved by technology

[0004] The present invention proposes an automatic plate counterweight mechanism for a direct plate-making machine, which solves the problems in the prior art, which generally include a coaxial ring groove arranged on a roller controlled by a controller, and a balancer sliding along the ring groove is arranged in the ring groove. The roller is also equipped with a retaining ring that fits tightly with the balance weight, and the position is measured manually. After the balance weight is moved to a suitable position, the balance weight is pressed tightly on the drum through the retaining ring. The adjustment of the weight is troublesome, the operation is time-consuming and labor-intensive, and the accuracy of the counterweight is low. The present invention sets the adjustment rod and the counterweight, the controller receives the sensor information, and the front driving force is provided by the cylinder part, and the protrusion and the groove cooperate to rotate. It is used to adjust the position of the counterweight to realize automatic counterweight. The structure is simple and manpower is saved.
