The plate fast tensioning device is composed of a front plate clamp, a contour pad, a roller, an adjustment screw, a rear plate clamp, a lever sleeve, an eccentric shaft, a compression spring, an eccentric pin, and a roller guide.
1. The working principle of the plate fast tensioning device
First, one end of the plate is positioned by the positioning device, and then loaded into the front plate clamp. Then, the other end of the plate is wound around the plate cylinder one week later, and the rear plate is loaded, and the adjustment screw is manually adjusted to be placed on the contour pad, thereby clamping the plate. Finally, in order to ensure that there is no slack and skew in the printing plate mounted on the plate cylinder, it is necessary to dial the lever sleeve and rotate the eccentric shaft. At this time, the eccentric pin on the top of the lever sleeve and the eccentric shaft is Will drive the contour pad to move axially to the plate cylinder, and at the same time, four contoured surface positions on the contour pad will be displaced along the axial direction of the plate cylinder, and the position of the contour surface will change. Push the roller guide and drive the lever sleeve up and down to achieve tensioning of the rear plate clamp.
2. Advantages of the plate fast tensioning device
(1) In the process of tensioning the printing plate, only the adjustment of the lever sleeve mounted on the rear plate clamp can keep the printing plate and the plate cylinder axially parallel, and fully ensure the printing plate in the plate cylinder shaft. Uniformity of force in the direction of the head and the circumference.
(2) After optimizing the structural design of the plate rapid tensioning device, the operation becomes very simple, which not only saves time and labor, but also improves production efficiency.
(3) The plate rapid tensioning device is designed with a plurality of high-precision contour spacers, and a spring is used to support the roller, and the rear plate clamp is supported by the eccentric shaft and the compression spring to ensure the balance of the printing plate. At the same time, it also makes the axial force in the plate cylinder uniform, which significantly improves the overprinting accuracy of the printed image.
Since the printing plate rapid tensioning device has been promoted and used by printing companies, it has been well received by the industry for its advantages of convenient use, convenient operation, and improved printing overprinting accuracy. You may wish to experience it too!
