Description

Technical Field

[0001] This utility model relates to the field of roll material processing technology, and in particular to a disc-type unwinding and winding device. Background Technology

[0002] A laminating machine is a mechanical device mainly used to bond two or more layers of the same or different materials together with a special adhesive. Existing laminating machines generally include a coating unit, at least two unwinding units and a winding unit. The strip wound on the unwinding unit is guided by guide rollers and then conveyed to the coating unit for lamination, and then guided to the winding unit for winding.

[0003] The winding and unwinding devices have similar structures, generally including supports at both ends, a roller frame between the two supports, and at least two winding rollers between the two roller frames. The two roller frames are rotatably mounted on the two supports. Driving the winding rollers to rotate achieves winding or unwinding of the strip, and driving the roller frame to rotate achieves switching between winding rollers. While such a winding mechanism can meet usage requirements to a certain extent, because the roller frames are directly mounted on the supports, when the weight of the strip wound on the winding rollers is large, the rotational fulcrum between the roller frame and the supports experiences significant forces, creating stress concentration and making it prone to damage. This reduces the service life and reliability of the winding mechanism.

[0004] Furthermore, existing take-up and unwinding mechanisms are generally fixed to the ground relative to the coil processing production line. When the take-up and unwinding positions of the strip deviate laterally, the take-up and unwinding rollers of the mechanism cannot be aligned with the strip, failing to achieve proper take-up and unwinding. During strip winding, if the axis of the take-up and unwinding rollers is not parallel to the surface of the strip, it will result in a problem where one end of the strip is tightly wound while the other is loosely wound. That is, the surface diameter of the wound strip will be unequal, and the larger diameter end will exert tension on the strip, which is detrimental to the winding operation. The wound strip may also collapse due to insufficient compaction. Utility Model Content

The roller support is fixed to a wall. The first disc and the second disc are provided with first and second roller mounting holes of the same size, which are symmetrically arranged with respect to the center of the first disc or the second disc.

[0007] Furthermore, the fixing device includes two sets of eccentric roller assemblies and two sets of roller assemblies. The eccentric roller assembly includes an eccentric roller support and an eccentric roller. The eccentric roller is disposed in the eccentric roller support through an eccentric rotating shaft. The eccentric roller is symmetrically disposed above the second disk, and the roller assembly is symmetrically disposed below the second disk.
