Problems solved by technology

In the existing technology, after recycling the cut off material, if it is directly put into the raw material kettle, there will be uneven melting of the liquid material, and when the film edge is directly crushed, the material will be soft, the winding will be messy, and the crushing will be uneven. Case
Especially when recycling multiple blowing production lines, it is difficult to unify and aggregate, and the soft multi-head plastic wrap cut strips are not easy to crush evenly

Abstract

The invention relates to the technical field of plastic preservative film production equipment, in particular to plastic preservative film slitting waste recycling equipment. The device is characterized by comprising an edge cutting device, a guiding and conveying device, a smashing device and a negative pressure conveying device, and the edge cutting device is installed at the rear end of a blowing device; the guiding and conveying device, the crushing device and the negative pressure conveying device are connected in sequence; a gathering roller pair set, a hot guiding and conveying part, a cold guiding and conveying part and a clamping guiding and conveying part of the guiding and conveying device are sequentially connected from front to back and installed on a guiding and conveying rack. A traditional structure is optimized, preservative film slitting waste can be efficiently recycled and smashed, time and labor are saved, smashing is uniform, and efficient recycling of the waste is facilitated.

Description

technical field [0001] The invention relates to the production equipment and technical field of plastic cling film, in particular to a plastic cling film slitting waste recycling equipment. Background technique [0002] In the production process of the plastic wrap, the gelatinous material needs to be blown into a cylindrical shape first, and after the cylindrical plastic wrap is flattened, the outer edges on both sides are cut off to obtain a double-layer finished plastic wrap. However, after being cut off, the remaining material needs to be collected and put into the raw material kettle again, and hot-melted to a liquid state to repeatedly participate in the blowing of the plastic wrap. In the existing technology, after recycling the cut off material, if it is directly put into the raw material kettle, there will be uneven melting of the liquid material, and when the film edge is directly crushed, the material will be soft, the winding will be messy, and the crushing will ...
