Description
Technical Field
The utility model relates to a rotary offset press, in particular to a rubber mounting structure of a rubber cylinder of the rotary offset press.
Background
A blanket cylinder of a rotary offset printing press includes a cylinder body and a blanket wrapped around an outer circumferential surface of the cylinder body. At present, there are two kinds of mounting means for the blanket on the cylinder body: one is a sleeve blanket cylinder, which is a method that a blanket is made into a hollow cylinder, is expanded by an air expansion shaft and then is installed on a machine, but the blanket is very expensive and cannot be replaced at present in China, and the blanket is the largest loss product in an offset press and cannot be accepted by expensive customers. Another mode is directly pasted the rubber cloth at the excircle surface of cylinder barrel through glue, and the shortcoming has the seam to exist after the rubber cloth twines a week on the cylinder, and the long-pending black phenomenon of ponding can appear in offset press during operation this seam, and ponding long-pending black can make the rubber cloth stick up the limit, and this can reflect the printed matter surface, influences printing quality.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide a rubber mounting structure of a rubber cylinder of a rotary offset press, which can reduce the production cost and ensure the printing quality.
The utility model is implemented by the following technical scheme:
rubber mounting structure of rotary offset press blanket cylinder, including cylinder barrel and blanket, the blanket wraps up in the outer peripheral surface of cylinder barrel, its characterized in that: the cylinder barrel is provided with a notch in the circumferential direction, a first insertion groove and a special-shaped hole which are adjacently arranged are arranged in the notch, a tightening shaft is rotatably arranged in the special-shaped hole, the shaft end of the tightening shaft is connected with a locking device, a second insertion groove is arranged on the outer circle surface of the tightening shaft, the two end portions of the rubber cloth are connected with a first clamp body and a second clamp body, the first clamp body is inserted into the first insertion groove, and the second clamp body is inserted into the second insertion groove.
The locking device comprises a worm wheel and a worm which are meshed with each other, the worm wheel is fixedly arranged at the shaft end of the winding shaft, the worm is rotatably arranged on a worm seat, and the worm seat is fixedly arranged on the end face of the roller barrel.
Locking device includes the fixing base, and the fixing base is at the terminal surface fixed mounting of cylinder barrel, and the fixing base is equipped with the locking hole and lets the axle head of rolling shaft wear to establish wherein, and the locking hole is locked with locking screw.
Above-mentioned technical scheme's rubber mounting structure of rotary offset press blanket cylinder, when carrying out the installation of blanket, at first cut into required size with the blanket, the first clamp and the second clamp of platelike are wrapped up to the available aluminum alloy lath in both ends, roll up the blanket at the outer peripheral surface of cylinder barrel after that, first clamp inserts first inserting groove, the second clamp inserts in the second inserting groove, rotate the axle of crimpleing afterwards, it is tighter more to make the blanket pull, thereby reach the blanket and tighten the effect, satisfy the offset press printing requirement. The mounting structure not only reduces the production cost, but also can ensure the printing quality because no seam raised edge exists.
