Abstract
The invention discloses a novel concave-convex plastic uptake product and a plastic uptake process, wherein the product is a lettering film and comprises an inner layer and an outer layer connected with the inner layer, wherein anti-slip grooves which are mutually communicated through connecting grooves are uniformly distributed on the upper surface of the outer layer, a first ventilation hole is formed in the inner layer, and a second ventilation hole which is distributed at intervals with the first ventilation hole is formed in the outer layer, so that the anti-slip effect is ensured, and the ventilation of the lettering film is ensured; the plastic sucking process makes the inner layer and the outer layer fit with heat conducting powder in the pressing process, and slowly pressurizes to make the upper mold and the lower mold fit gradually, so that the joint part of the inner layer and the outer layer is thermally bonded in a layered and progressive manner, and the lamination is replaced by singly completing the double-layer or multi-layer lettering film and adopting viscose to bond, so that the lamination is prevented from being unstable, and the process of the invention simplifies the subsequent manual pasting process of the lettering film with a multi-layer structure for integral molding.
Description
Technical Field
The invention relates to a novel concave-convex plastic sucking product and a plastic sucking process, and belongs to the technical field of plastic sucking processing.
Background
The plastic product is mainly made of various plastic materials such as PVC, PET, PP, PS, GAG, flocking and the like with high quality, and is used for producing high-grade and various-specification electronic plastic packages, stationery plastic packages, toy plastic packages, hardware plastic packages, food plastic packages and daily chemical gift art plastic packages.
The plastic sucking process is mainly characterized in that after a flat plastic hard sheet is heated and softened, the plastic hard sheet is adsorbed on the surface of a die in vacuum and is cooled and molded, and the plastic sucking process is widely applied to the fields of plastic packaging, lamp decoration, advertisement, decoration and the like. The plastic suction molding is also called vacuum molding, and is one of thermoplastic plastic thermoforming methods, and the process flow is as follows: clamping the sheet-shaped or plate-shaped material on the frame of the plastic sucking device, heating and softening, adsorbing the sheet-shaped or plate-shaped material on a die through an air channel at the edge of the die by vacuum, and cooling for a short time to obtain a 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 the excessive lamination in the process. Some processes only use glue to adhere after a single-layer lettering film, and the adhesion effect is poor, so that a plastic sucking 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 sucking product and a plastic sucking process, which adopts the following technical scheme:
according to the invention, the novel concave-convex plastic uptake product is provided as a lettering film, can be applied to clothing or leather bags according to requirements, comprises an inner layer and an outer layer connected with the inner layer, wherein anti-slip grooves which are mutually communicated through connecting grooves are uniformly distributed on the upper surface of the outer layer, each anti-slip groove comprises an anti-slip disc arranged at the center of the anti-slip groove and a plurality of anti-slip blocks arranged around the anti-slip disc, a first liquid discharge groove is formed between the anti-slip disc and each anti-slip block, a second liquid discharge groove is formed between the anti-slip blocks, and the second liquid discharge grooves are communicated with the connecting grooves.
