Abstract
The invention discloses a novel concave-convex plastic uptake product and a plastic uptake process, wherein the product is a lettering film which comprises an inner layer and an outer layer connected with the inner layer, anti-skid grooves which are mutually communicated through connecting grooves are uniformly distributed on the upper surface of the outer layer, a first air hole is formed in the inner layer, and a second air hole which is distributed at intervals with the first air hole is formed in the outer layer, so that the anti-skid property and the air permeability are ensured; the plastic uptake process enables the inner layer and the outer layer to be matched with heat conducting powder in the pressing process, slowly pressurizes and enables the upper die and the lower die to be gradually attached, so that the attached parts of the inner layer and the outer layer are gradually and increasingly hot attached, the adhesive attaching is adopted to replace the independent completion of double-layer or multi-layer lettering films, the attaching is prevented from being insecure, and the subsequent manual adhering process of the multi-layer lettering film is simplified due to the integrated forming process.
Description
Technical Field
The invention relates to a novel concave-convex plastic uptake product and a plastic uptake process, and belongs to the technical field of plastic uptake processing.
Background
The plastic uptake product is mainly made of various plastic materials such as high-quality PVC, PET, PP, PS, GAG, flocking and the like, and is used for producing high-grade and various specifications of electronic plastic uptake packages, stationery plastic uptake packages, toy plastic uptake packages, hardware plastic uptake packages, food plastic uptake packages and daily chemical gift handicraft plastic uptake packages.
The plastic uptake is a plastic processing technology, and the main principle is that after a flat plastic hard sheet is heated and softened, the plastic hard sheet is absorbed on the surface of a mould in vacuum, cooled and formed, and the plastic hard sheet is widely applied to the fields of plastic packaging, lamp decoration, advertisement, decoration and the like. The plastic suction forming is also called vacuum forming and is one of thermoplastic plastic thermal forming methods, and the process flow is as follows: clamping the sheet or plate material on the frame of the plastic sucking device, heating to soften, passing through the air channel at the edge of the mold, sucking the sheet or plate material onto the mold by vacuum, and cooling for a short time to obtain the molded plastic product. The equipment adopted by the method is generally simpler, the forming speed is high, the operation is easy, but the lettering film with a double-layer or multi-layer structure is not easy to form in the operation process of manufacturing the lettering film, and the reason is that the double-layer or multi-layer structure is damaged by excessive stitching in the process. Some processes only use glue to adhere after the single-layer lettering film, and the adhesion effect is not good, so that a plastic uptake process capable of solving the existing problems is urgently needed
Disclosure of Invention
In order to solve the problems, the invention provides a novel concave-convex plastic uptake product and a plastic uptake process, which adopt the following technical scheme:
the invention provides a novel concave-convex plastic uptake product which is an engraved film and can be applied to clothes or leather bags as required, the novel concave-convex plastic uptake product comprises an inner layer and an outer layer connected with the inner layer, anti-skid grooves which are mutually communicated through connecting grooves are uniformly distributed on the upper surface of the outer layer, each anti-skid groove comprises an anti-skid disc and a plurality of anti-skid blocks, the anti-skid discs are arranged at the centers of the anti-skid grooves, the anti-skid blocks are arranged on the periphery of the anti-skid disc, a first liquid discharge groove is formed between each anti-skid block, a second liquid discharge groove is formed between each anti-skid block, and the second liquid discharge grooves are communicated with the connecting grooves.
