The reel-up is a linkage arranged at the very end of the paper machine. Its main function is to roll the paper web produced by paper machine into paper roll, which is convenient for one-step processing while post-processing. In paper production, the performance of the winder directly affects the quality of the rolled paper, the structure of the rolled paper, the loss of the paper, the overall production efficiency of the paper machine and post-processing procedures and the economic benefit of enterprises; at the same time, the printing quality of the printing user, the printing efficiency and the runnability of the printing process are also affected. The operating performance of the paper winding machine directly affects the production efficiency of the paper machine.

The paper winding machine can be divided into two types according to the curling principle: reel-to-reel and cylinder reel. The winding roll of a reel-to-reel machine is directly driven to rotate, and when the linear speed of paper is constant (corresponding to the linear speed of the paper machine), the angular speed of the paper roll should be continuously reduced.

The free end 114 is provided with a pair of pressing arms 115, and a gap for fixing the winding roller 200 is formed between the pair of pressing arms 115.

As shown in fig. 1 and 2, an acceleration mechanism 120 for accelerating the winding roller 200 is disposed between the pair of pressing levers 111, the acceleration mechanism 120 includes a support plate 121, an acceleration roller 122, a driving device (not shown) for driving the acceleration roller 122, and a pair of first hydraulic levers 123, the pair of first hydraulic levers 123 are respectively disposed inside the pair of pressing levers 111, each first hydraulic lever 123 is disposed along a length direction of the pressing lever 111, a base of the first hydraulic lever 123 is fixed inside the pressing lever 111, and a movable lever of the first hydraulic lever 123 is directed to the free end 114. The support plate 121 includes a bottom plate 1211 and a pair of end plates 1212 at both ends of the bottom plate 1211, and both ends of the speed increasing roller 122 are connected to the pair of end plates 1212, respectively. The bottom plate 1211 is disposed on a side of the pair of end plates 1212 close to the first hydraulic rod 123, and the bottom plate 1211 is connected to the movable rod of the first hydraulic rod 123. The speed-increasing roller 122 is movable in the lengthwise direction of the pressing lever 111 under the control of the first hydraulic lever 123 to contact the winding roller 200 disposed at the free end 114 and to rotate the winding roller 200 by virtue of the frictional force between the speed-increasing roller 122 and the winding roller 200.

The pair of end plates 1212 are slidably engaged with the pair of pressing bars 111, respectively. Each pressurizing rod 111 is provided with a slide rail 116 on one side facing the support plate 121, the slide rail 116 is arranged along the length direction of the pressurizing rod 111, and the pair of end plates 1212 are provided with sliders 1213, and the sliders 1213 are slidably embedded in the slide rail 116. Since the pressurizing rod 111 is not stationary, the sliding of the speed-increasing roller 122 is not stable in the process of the left-right rocking at all times, and the movable rod of the first hydraulic rod 123 is subject to a large shearing force, which is likely to be damaged.

A gap for fixing the winding roller 200 is formed between the pair of clamp arms 1332.

Taking the view angle of fig. 1 as an example, the operation principle of the winding mechanism 100 for a paper machine is as follows:

s1, during the winding process, the movable lever of the second hydraulic lever 117 is retracted, and the pressing arm 115 on the right side of the winding roller 200 presses the winding roller 200 against the winding driving roller 132, maintaining the pressure between the two rollers.

S2, when the winding roller 200 reaches a certain diameter, the paper is cut, the movable rod of the second hydraulic rod 117 extends to push the pressing arm 115 away, and during the process of moving away, the pressing arm 115 on the left side of the winding roller 200 pushes the winding roller 200 away.

S3, the roll changing lever 1331 is rotated clockwise to place a new sheet winding roll 200 on the guide rail 131. The paper roll 200 will have an initial velocity toward the right due to the pushing of the roll changing lever 1331, and will continue to roll along the guide rail 131 toward the right, contacting the pressing arm 115 on the right side of the pressing lever 111 (the pressing lever 111 has just completed the operation of pushing away the original paper roll 200, and has not completed the reset during the reset process).

S4, the movable rod of the first hydraulic rod 123 extends to push the speed-increasing roller 122 (driven by the motor 124) toward the winding roller 200, and the winding roller 200 is held in close contact with the speed-increasing roller 122 by its own weight. The speed-increasing roller 122 drives the winding roller 200 to rotate in the process of returning the pressing lever 111 by virtue of the frictional force between the speed-increasing roller and the winding roller 200.

S5, when the pressure lever 111 is completely returned, the winding roller 200 has already reached a certain initial speed, and the movable lever of the first hydraulic lever 123 is retracted to retract the speed increasing roller 122 before the winding roller 200 comes into contact with the winding-driving roller 132. Subsequently, the roll paper roller 200 is brought into contact with the roll paper driving roller 132 by the pressing arm 115, and the pressure is maintained.

To sum up, the embodiment of the utility model provides a winding mechanism 100 for paper making machine, it is on traditional winding mechanism 100's basis, speed increasing roller 122 has been add in pressure lever 111's inboard, after roll change at every turn, this speed increasing roller 122 is under first hydraulic means's drive, with the winding roller 200 contact that newly trades, rely on and the frictional force between the winding roller 200, drive the rotation of winding roller 200, make this winding roller 200 possess certain speed when contacting with stock form drive roller 132, with the speed difference between reduction winding roller 200 and the stock form drive roller 132, thereby reduce the pulling force that roll change in-process paper received, prevent the condition of disconnected paper.
