Description

Automatic rolling and reel changing mechanism

Technical Field

The utility model relates to winding equipment, in particular to an automatic winding and reel changing mechanism.

Background

The rolling machine is relatively common mechanical equipment in industrial production, and generally comprises a friction rolling machine and a central rolling machine, wherein the friction rolling machine drives a rolling shaft to rotate through a friction roller, so that the film material is rolled, and the rolling machine is applied to scenes with thicker film material and heavier material roll after rolling. When the friction type winding machine is used for winding, the film can be smoothly wound on the winding shaft only by ensuring that the winding shaft is in close contact with the friction roller. The utility model provides a be CN218753971U, the publication is the automatic roll change material receiving mechanism of film blowing machine that 28 days of 2023 years 3 months disclose, this kind of automatic roll change material receiving mechanism includes the frame, be equipped with the storage station of placing reserve wind-up roll, change the roll change station and the rolling station of wind-up roll in proper order along the material direction of transfer in the frame, the rolling station is including rotating the wind-up leather roller and the drive wind-up leather roller pivoted rolling motor that set up in the frame, be equipped with the fly cutter subassembly that cuts off film in the roll change station, its characterized in that: the utility model provides a storage station, including rotating the arm of placing that sets up in frame both sides inner wall, place arm one end and be equipped with the first breach of placing reserve wind-up roll, the other end is connected with its pivoted first cylinder of drive, the both ends of rolling leather roller all overlap and are equipped with the reel change rotor plate, and the reel change rotor plate drives its rotation through reel change drive assembly, and when the reel change rotor plate was rotated to being close to the rolling station, one side of placing the arm was equipped with the second breach that supplies reserve wind-up roll to place, place arm and reel change rotor plate dislocation set, reserve wind-up roll falls into in the second breach along with placing arm change rotor plate department, the rolling station is including rotating the translation arm that sets up in frame both sides inner wall, be equipped with the fork of placing the wind-up roll on the translation arm, reserve wind-up roll changes to fall into in the fork along with the reel change rotor plate. The automatic reel-changing and material-collecting mechanism can simplify the structure that the standby winding shaft enters the winding station, and improves the efficiency. However, the first notch on the placing arm of the automatic reel changing and collecting mechanism and the second notch on the reel changing and collecting mechanism are both L-shaped with the opening facing to the left, and when the reel is replaced by adopting the structure, the placing arm simply plays a role in transferring the reel to the reel changing and collecting plate, and in the subsequent transferring of the reel, the placing arm cannot play other roles. Therefore, after the winding shaft is transferred to the second notch on the reel-changing rotating plate, when the winding shaft can be pressed on the friction roller under the action of gravity, the side wall of the reel-changing rotating plate is not contacted with the winding shaft, and the winding shaft cannot be supported, and in this case, the state of the winding shaft is unstable and is easy to fall from the second notch; when the reel-changing rotating plate can support the winding shaft, the state that the winding shaft cannot be tightly contacted with the friction roller is represented. Although both the above-mentioned cases can be solved by slightly inclining the reel-changing rotating plate, in either case, when the reel spool moves to the side of the friction roller with the rotation of the reel-changing rotating plate, the effect of gravity on pressing the reel spool against the friction roller will gradually decrease as the contact position of the reel spool with the friction roller changes, and at this time, it is difficult for the reel spool to maintain a state in close contact with the friction roller, which may cause the reel spool to be unable to reel at the initial stage of winding, thereby affecting the whole winding process, and the stability of the transfer process of the reel spool is insufficient.
