Casting production mechanism and casting manufacturing method for degradable express waybill labeling paper

Abstract

The invention relates to the technical field of casting film production, in particular to a casting production mechanism and casting manufacturing method for degradable express waybill labeling paper.The casting production mechanism comprises a machine frame, a feeding bin, a melting mechanism, a casting roller, a shearing mechanism and a rim charge recycling mechanism, wherein the rim charge recycling mechanism comprises a transferring assembly, a cutting assembly and a mixing assembly; the cutting assembly comprises positioning rods and a cutter which is in transmission connection with a conveying part, and the conveying part is used for transferring and conveying rim charge sections; and the mixing assembly comprises a mixing bin, a supporting part and a transmission part, wherein thetransmission part is correspondingly connected with the supporting part and the conveying part. According to the casting production mechanism, the rim charge sections are laid on the supporting part in unfolding structures through the conveying part, initial coating and mixing of the rim charge sections and new materials are realized under driving of weights of the new materials, then the conveying part drives the supporting part to move, and the circumferential coating, adhesion and mixing of the rim charge sections and the new materials are realized; and therefore, the technical problem thatin the prior art, layering occurs in the melting process of the new materials and the rim charge sections after separation is solved.

Description

technical field [0001] The invention relates to the technical field of casting film production, in particular to a casting production mechanism and a manufacturing method of degradable courier slip labeling paper. Background technique [0002] Various films, stickers and other products produced by casting have been widely used in daily life. In the production process of cast film, the edge material will be cut online and mixed with new material at a ratio of no more than 10%. Afterwards, it can be reused again. However, due to the lighter side material, the side material and the new material are separated during the mixing process, resulting in poor quality of cast film due to uneven mixing. [0003] As we all know, after the film produced by casting is processed by subsequent stretching and other production processes, because the edges are mostly used for fixing, clamping, etc., they need to be damaged, so the edges need to be cut to reduce production costs. , The side mat...

[0002] Various films, stickers and other products produced by casting have been widely used in daily life. In the production process of cast film, the edge material will be cut online and mixed with new material at a ratio of no more than 10%. However, due to the lighter side material, the side material and the new material are separated during the mixing process, resulting in poor quality of cast film due to uneven mixing

[0003] As we all know, after the film produced by casting is processed by subsequent stretching and other production processes, because the edges are mostly used for fixing, clamping, etc., they need to be damaged, so the edges need to be cut to reduce production costs. , The side material is reused when the mass ratio of the side material to the new material is not greater than 1 / 9, so as to ensure the quality of the cast film is lowered, and the production cost is reduced while reducing the amount of production waste; at the present stage, the field of trademark sticker production Among them, the scrap material is mostly reused by mixing the scrap material with the virgin material and then liquefied. However, because the scrap material is a membrane structure, its weight is light and its surface area is large. Compared with the granular structure of the virgin material, it is easy to float during the melting process. , resulting in the formation of delamination of new material and edge material, resulting in a decrease in the uniformity of the casting solution, resulting in technical problems of poor quality of the casting film
