Detailed Description
An automatic pressure roller structure of a puller in an offset press is disclosed, as shown in fig. 1 to fig. 3, comprising a pair of mounting plates 1, a pressure roller 2 which can rotate and swing is arranged between the two mounting plates 1, and a puller roller 3 which can rotate and can be combined with or separated from the pressure roller 2 is also arranged at the side of the pressure roller 2 and between the two mounting plates 1; an air cylinder 4 is arranged on the outer side wall of the mounting plate 1 on one side, a pressing cam 5 capable of pressing or separating the pressing roller 2 and the puller roller 3 is arranged on the inner side wall of the mounting plate 1, and a transmission structure for driving the pressing cam 5 to rotate is arranged between a telescopic shaft of the air cylinder 4 and the pressing cam 5; a pressure regulating valve 6 for regulating the pressure of the cylinder 4 is also arranged on the mounting plate 1 on one side. In the embodiment, the pressing cam 5 adopts an eccentric wheel, so that the eccentric wheel is convenient to process and low in cost; the two press rollers 2 are respectively positioned at two sides of the puller roller 3, the combination and the separation of each press roller 2 and the puller roller 3 are respectively realized through the combination and the press cam 5 at the same side, and the combination and the press cam 5 at each side is provided with an air cylinder 4 for controlling the rotation of the combination and the press cam 5. The pneumatic connection mode between the pressure regulating valve 6 and the cylinder 4 belongs to the prior art; the connection relationship between the position of the pull head roller 3 and the position of the two press rollers 2 also belongs to the prior art.
The transmission structure comprises a transmission cam 7 hinged with a telescopic shaft of a vertically arranged cylinder 4, a rotatable transmission shaft 8 is arranged between the two mounting plates 1, the transmission cam 7 is sleeved on the transmission shaft 8, and pressing convex wheels 5 are arranged at two ends of the transmission shaft 8. The telescopic motion of the telescopic shaft of the cylinder 4 drives the transmission cam 7 to rotate, so that the transmission cam 7 drives the transmission shaft 8 to rotate, and the transmission shaft 8 drives the two pressing cams 5 on the transmission shaft to rotate, so that the pressing or separating of the pressing roller 2 and the pull head roller 3 is realized. The pressing convex wheels 5 are arranged at the two ends of the transmission shaft 8, so that the force applied by the pressing convex wheels 5 to the pressing roller 2 is more balanced, and the pressing force of the pressing roller 2 and the pull head roller 3 is kept stable.
But be provided with relative mounting panel 1 wobbling swing arm 9 on the inside wall of two mounting panels 1 respectively, the both ends of compression roller 2 are rotationally connected on the swing arm 9 that corresponds the end, and every swing arm 9 all contacts with the flange that closes pressure cam 5 that corresponds the end. The closing and pressing cam 5 rotates to drive the swing arm 9 to swing, so that the swing arm 9 drives the pressing roller 2 to swing, and closing and pressing or separation of the pressing roller 2 and the pull head roller 3 are realized.
The pressure regulating valve 6 is also provided with a pressure gauge 10, which is convenient for visually reading pressure data and is more beneficial to the adjustment of the pressure combination precision.
