Description

Technical Field

[0001] The utility model relates to the technical field of recycling devices, and more specifically, to a recycling device for trimming waste edges of plastic films for farmland. Background Art

[0002] When producing micro-nano laminated fully biodegradable plastic films for farmland, according to a special mold designed by a unique micro-nano lamination technology, in order to ensure that the layer structure of the product is not disordered, after coming out of a special die head, the confluence suture formed by the tube blank of the conventional blown film die will be more obvious, which will cause the film in the confluence line area to be thicker. Therefore, when winding, it is necessary to trim the confluence line area.

[0003] If the trimmed waste edges are wound onto a paper tube synchronously with the finished product, the relatively thick waste edges will accumulate, resulting in elevation. When winding, the tension at other points will be uneven, leading to a decline and instability in the winding quality. Therefore, the trimmed waste edges need to be recycled separately. If a trimming machine is selected, it is necessary to change the roll after accumulating to a certain extent. During the roll change process, there is a risk of unstable trimming, which may cause failure to timely traction, resulting in roll entanglement and affecting production. Therefore, a recycling device with continuity and stability needs to be selected. Summary of the Utility Model
