Description

Technical Field

[0001] The utility model relates to the technical field of protective film production equipment, in particular to an automatic roll-changing and winding device for protective film edge materials. Background Art

[0002] Protective film is a thin and soft transparent sheet made of plastic, adhesive, rubber or other materials. Protective film is widely used in electronic appliances, machinery, printing and other industries. Whether the protective film is made by blown film or cast film process, the edge material needs to be cut continuously during the processing because of the uneven distribution of the edge material.

[0003] The existing waste material system is to vacuum extract and crush it before adding it to the core layer. However, the intermediate recycling and reuse of the waste material often leads to crystal point problems in the film, affecting product quality, so the waste material needs to be collected.

[0004] The traditional winding device needs to pass the tube core and change the roll manually. At the same time, it is easy for the high-viscosity edge material to stick to the traction roller or the tool to wear and fail to cut the edge material, causing the edge material to curl into the product and cause the film to break and stop. In the crushing process, the debris will fall on the film and affect the quality, thereby reducing the product qualification rate.

[0005] Therefore, how to provide an automatic roll-changing and winding device for protective film edge material to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0006] In view of this, the purpose of the present application is to provide an automatic reel-changing and winding device for protective film edge material, so as to solve the problem that traditional winding devices need to thread a tube core and perform manual reel changing, and at the same time, the edge material is easily adhered to the traction roller due to high viscosity edge material or the edge material is worn by the tool and is not cut off, thereby causing the edge material to curl into the product and cause film breakage and shutdown. In the crushing process, the debris will fall onto the film and affect the quality, thereby reducing the product qualification rate.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0038] When in use, the edge material passes through the limiting double rollers 3. At this time, the swing motor 9 drives the movable block 10 to swing along the swing mechanism 4 through the screw rod 15, thereby driving the edge material to swing horizontally, so that the edge material can be wound up on the air expansion shaft with a left and right swing, and the winding amount is increased, thereby reducing the frequency of changing rolls.

[0039] A cross bar 22 is fixedly connected to one side of the automatic winding mechanism housing 2, a first traction mechanism 23 and a second traction mechanism 24 are installed at the bottom end of the cross bar 22, a second cylinder 21 is installed at the top end of the cross bar 22, and a tensioning roller 25 is installed at the telescopic end of the second cylinder 21;

When one of the air expansion shafts has completed winding, the cutting mechanism 11 is started and the edge material is cut off. Then the air expansion shaft contracts, and the edge material falls onto the conveyor belt for transportation under the action of gravity. At this time, the two air expansion shafts exchange positions and continue to wind up, with a high degree of automation and uninterrupted winding.
