Description
Technical Field
[0001] The utility model belongs to the technical field of printing equipment and relates to a backrest type double-roller double-station rotary type non-stop surface winding mechanism. Background Art
[0002] The existing film winding devices are divided into center winding and surface winding. Center winding means that the film is wound on the material shaft, the motor drives the material shaft to rotate, the material shaft drives the material roll to rotate, and the film is wound to complete the winding. In the process of center winding, as the roll diameter increases, in order to maintain the stability of the film tension, the torque output by the motor will become larger. Therefore, the larger the roll diameter, the greater the power required of the motor. In addition, the control system of center winding is more complicated, requiring the roll diameter to be resolved or the tension sensor to feedback the tension to maintain the constant tension. Surface winding means that the surface of the roll is attached to the backing roller, the backing roller is driven by the motor, the backing roller is active, and the friction force drives the roll to rotate to complete the winding. In the surface winding method, because the point of force is on the surface of the roll, the roll diameter increases, and the torque increases accordingly, so the motor power is small and the output is constant.
[0003] There are two existing surface winding schemes. One is to place two backing rollers horizontally and in parallel, and place the material roll between the two rollers, in the upper position. The material roll and the center line of the two backing rollers form an equilateral triangle structure. Friction is required to drive the material roll, and the pressure required to generate friction is generated by the weight of the material roll. The disadvantage of this scheme is that the pressure cannot be controlled. When the weight of the material roll is too large, the surface of the material roll will be distorted and deformed due to the influence of pressure, affecting the printing quality. The second is to use a backing roller with a larger diameter, the center line of the material roll is arranged horizontally with the center line of the backing roller, and the roller structure is installed at both ends of the material shaft, and the rollers are placed on two horizontal guide rails. Use a swing arm to move the material shaft roller to press the material roll against the backing roller to generate the pressure required for the friction force of the material roll drive. This scheme is equipped with a special swing arm for roll change. When changing rolls, the spare material shaft on the swing arm presses downward to the backing roller vertically above the center line of the backing roller. When changing rolls, the raw material roll is unloaded, and the new material roll on the roll change swing arm swings to a horizontal position to complete the roll change. The backing roller of this solution has a large diameter and a complicated roll-changing swing arm structure, so the cost is high. In addition, this solution does not have a tension roller, which is prone to uneven winding due to insufficient tension. Utility Model Content

[0044] The material roll 4 is inserted on the material shaft A, and the starting position of the material shaft A3 is on the rotary frame. As the winding diameter increases, the material shaft A3 moves toward the horizontal guide rails G20 and M21 and is mounted on the horizontal guide rails G20 and M21. The material shaft A3 is pressed against the backing roller A1 by the material shaft pressure arm. When the backing roller A1 rotates, the material roll 4 is driven to rotate under the action of friction to be wound.
[0045] When changing the roll, after the material film is wound from the material shaft A3 to the material shaft B7, the material shaft A3 and the raw material roll are unloaded, the rotary frame rotates, and the material shaft B7 rotates to the original position of the material shaft A3, completing the station exchange and entering the next winding cycle.
