Description

Anti-pull-out anti-counterfeiting bottle cap assembling process Technical Field The invention relates to the technical field of bottle caps, in particular to an anti-pull-out anti-counterfeiting bottle cap assembly process. Background The existing common white spirit bottle caps in the market comprise an inner plug, an inner sleeve (also called a bottle mouth, a wine pouring device, a connecting sleeve and the like in the market, hereinafter collectively called an inner sleeve), an inner cap, an upper cap (comprising a top sheet and an upper cap, which are combined by welding or forced pressing, so that the two accessories are collectively called an upper cap hereinafter), and a lower sleeve, wherein the common white spirit bottle caps are combined into bottle caps by the five accessories, and are used as basic products in the current bottle cap industry. The existing anti-counterfeiting technology of the white spirit bottle cap has the defects that: 1. under a certain physical pulling force in the vertical direction, the bottle cap can be pulled out from the bottle or the upper cap can be pulled out from the inner cap. 2. Under the high-temperature state of boiling or steam, the bottle cap can be pulled off from the bottle and is easy to recover. 3. The anti-counterfeiting foundation of the white spirit bottle cap in the current market is based on transverse rotary release opening, so that anti-counterfeiting teeth or anti-counterfeiting parts such as anti-counterfeiting petals, bursting rings, connecting sheets and the like are broken and destroyed. 4. The limitation of raw material adoption is that because the inner sleeve contacted with the wine is mostly made of PET material, the material is easy to deform at about 75 degrees, so that the common bottle cap is not resistant to high temperature, the strength and toughness of the material are insufficient, and the bottle cap is easy to pull out under physical tension after being put on the bottle cap, and the bottle cap can be pulled out from the bottle under a certain tension effect, so that the anti-counterfeiting performance of the bottle cap is greatly reduced. 5. At present, a mode that an inner sleeve is inlaid in a metal steel ring is also adopted in the market, but injection molding cost is high, an injection mold is easy to crush in production, and the metal steel ring is small in deformation, so that a glass bottle mouth is easy to fracture when the metal steel ring is pressed with a bottle, and sealing and potential safety hazards exist in the process of transporting white wine and preserving food and drink. 6. The bottle caps in the existing market have no obvious visual damage effect on the whole appearance after the anti-counterfeiting points are damaged, and damage marks are not obvious, so that the bottle caps are not easy to identify by consumers after being simply repaired and re-put on the bottle caps. 7. At present, the white spirit bottle cap is mainly assembled by an inner sleeve, an inner cover and an inner plug, then the inner sleeve, the inner cover and the inner plug are pressed into a lower sleeve, and then an upper cover is pressed on the inner cover, so that a bottle cap whole is formed. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide an anti-pull-out anti-counterfeiting bottle cap assembly process. In order to achieve the aim, the invention adopts the technical scheme that the anti-pulling anti-counterfeiting bottle cap assembly process comprises an inner plug, an inner sleeve, an inner cover, an upper cover and a lower cover, wherein an anti-pulling piece is arranged between the upper cover and the lower cover, and the upper cover is in clamping fit with the lower cover through the anti-pulling piece; the inner sleeve is of an integral molding structure formed by double-color/double-material injection molding, and comprises a bottle mouth part made of food-grade plastic and a bottle neck part made of high-temperature-resistant high-strength plastic, wherein the bottle mouth part is of a cover-shaped structure, the bottom of the bottle mouth part is of a circular ring shape, a liquid outlet is formed in the top of the bottle mouth part, the bottle neck part is of a circular tube-shaped structure, a plurality of frangible pieces are arranged between the bottle mouth part and the bottle neck part, the bottle mouth part is in clamping fit with the bottle neck part through the frangible pieces, the outer surface of the bottle mouth part of the inner sleeve is provided with threads, the inner cavity wall of the inner sleeve is also provided with threads, the bottle mouth part of the inner sleeve is in threaded connection with the inner cover, the inner cavity of the inner cover is provided with a first step, the inner cavity wall of the upper cover is correspondingly provided with a first clamping block in clamping fit with the first step, the bottle neck part of the inner sleeve is ar
