Go up compression roller 2 and lower compression roller 3 and can be driven by a gear motor respectively and rotate, like this, the synchronism can be poor, and two gear motor control respectively with the converter certainly can have the error, and energy consumption and equipment north-city all can increase, go up compression roller assembly gear motor then reuse cylinder control lift also can appear both ends weight different, cause about heavy, can block owner, consequently can also following the setting: an upper intermediate gear 8 and a lower intermediate gear 9 which are meshed with each other are arranged at the downstream positions of the upper pressing roller 2 and the lower pressing roller 3 (the movement of the sheet material is from the upstream to the downstream), the upper pressing gears 10 are respectively arranged at the two ends of the upper pressing roller 2, the lower pressing gears 11 are arranged at the two ends of the lower pressing roller 3, the lower pressing gears 11 are meshed with the lower intermediate gear 9, and the upper intermediate gear 8 and the upper pressing gear 10 are always meshed no matter how the upper pressing roller 2 moves, so that the stroke of the second cylinder 7 cannot be too large to separate the upper intermediate gear 8 from the upper pressing gear 10; the diameters of the upper pressing gear 10, the lower pressing gear 11, the upper intermediate gear 8 and the lower intermediate gear 9 are equal.

A traction device is also installed at the upstream position of the upper pressing roll 2 and the lower pressing roll 3: including diameter with last compression roller 2 and 3 equal rubberizing rollers 12 and lower rubber roll 13 of lower compression roller, rubberizing roller 12 also can reciprocate, as with the moving mode of last compression roller 2, promptly: the first mounting panel 14 of erectting is installed on frame 1, the middle part fretwork of first mounting panel 14, first sliding tray 16 of direction about fretwork position both sides are opened, then install a first sliding plate 15 at the fretwork position, the both ends of first sliding plate 15 are located first sliding tray 16, the center pin at the both ends of rubberizing roller 12 passes through the bearing and installs on first sliding plate 15, then install a first cylinder 17 in first mounting panel 14 upper end, the output of first cylinder 17 stretches into fretwork position after-fixing in the upper end of first sliding plate 15 downwards, thereby drive first sliding plate 15 and drive rubberizing roller 12 by first cylinder 17 and reciprocate.

Rubber roll gears 18 are installed at two ends of a lower rubber roll 13, the rubber roll gears 18 are meshed with an intermediate gear 19, the intermediate gear 19 is meshed with a lower pressing gear 11, the diameters of the rubber roll gears 18, the intermediate gear 19 and the lower pressing gear 11 are equal, in this way, the whole device only needs one speed reducing motor 24, the speed reducing motor 24 drives the lower pressing roll 3 to rotate, as long as the lower pressing roll 3 rotates, the upper pressing roll 2 and the lower pressing roll 13 are driven by the upper intermediate gear 8, the lower intermediate gear 9 and the intermediate gear 19 to rotate, and along with the movement of the plate, under the action of friction force, the upper pressing roll 12 is also rotated.

The upper intermediate gear 8, the lower intermediate gear 9 and the intermediate gear 19 are all mounted to the frame 1.

The upper rubber roller and the lower rubber roller are both of hollow structures, and cooling water is introduced into the hollow structures.

Still include the heat conduction oil system, the heat conduction oil system includes heat conduction oil tank 25, heat conduction oil tank 25 connects out an oil pipe 20 and an oil return pipe 21 respectively, oil pipe 20 and oil return pipe 21 are connected on the center pin of last compression roller 2 and the one end of lower compression roller 3 through swivel joint 22 respectively, of course, from last compression roller 2 advance, lower compression roller 3 goes out also, lower compression roller 3 advances, go out also to go out also, as long as can form the return circuit, can be in this embodiment with lower compression roller 3 as an example, install an intermediate oil pipe 23 at the other end of lower compression roller 3 through swivel joint 22, the tip of the center pin of the other end of intermediate oil pipe 23 is installed at the tip of the center pin of last compression roller 2 through a swivel joint 33.

The using process is as follows: the positions of the lower press roll 3 and the lower rubber roll are fixed, so that the positions of the upper press roll 2 and the upper rubber roll 12 are adjusted; the semi-finished plate sequentially passes through the space between the upper rubber covered roller 12 and the lower rubber covered roller 13 and the space between the upper press roller 2 and the lower press roller 3, the first air cylinder 17 and the second air cylinder 7 are started, the upper rubber covered roller 12 and the upper press roller 2 move downwards to gradually extrude the plate, the first air cylinder 17 and the second air cylinder 7 are stopped and maintained, in the adjusting process, because all the gears are meshed and connected and the upper press gear 10 and the upper intermediate gear 8 are always kept in a meshed state, the upper press roller 2, the lower press roller 3 and the lower rubber covered roller 13 always rotate, but the stroke of the first air cylinder 17 and the stroke of the second air cylinder 7 are limited, so that even if the rotation is slight, the influence on the plate cannot be caused; after the adjustment is completed, the whole PVC plate production line can be started.

Other technical features than those described in the specification are known to those skilled in the art.
