Automatic plastic cover UV screen printing device and screen printing method thereof

Abstract

The invention discloses an automatic plastic cover UV screen printing device and a screen printing method thereof. The automatic plastic cover UV screen printing device comprises a feeding station, a cover arranging station, a screen printing station and a discharging station which are sequentially arranged, the feeding station comprises a vibration discharging assembly, and the cover arranging station comprises a feeding circulating conveying belt. A discharging table is arranged on the screen printing station corresponding to the end portion of the discharging end of the feeding circulating conveying belt, a rotary disc is erected on one side of the discharging table, and a movable rotating assembly used for abutting against the end portion of a bottle cap and driving the bottle cap to rotate independently is installed at the corresponding position of a fixing shaft on the uppermost portion of the rotary disc. A UV screen printing assembly moving in a reciprocating mode is installed above the fixing shaft on the uppermost portion of the rotary disc, the bottommost end of the rotary disc is the discharging station, the discharging station comprises a cover unloading assembly matched with the fixing shaft, and a discharging circulating conveying belt is arranged below the cover unloading assembly. According to the automatic plastic cover UV screen printing device and the screen printing method thereof, continuous production, one-by-one sleeving, one-by-one screen printing and one-by-one discharging are achieved, the screen printing efficiency is high, the screen printing effect is good, the cost is low, and the use requirements of small-batch and small-and-medium-sized production and machining are met.

Description

Technical field: [0001] The invention relates to the field of bottle cap production and processing, and mainly relates to an automatic plastic cap UV silk screen printing device and a silk screen printing method thereof. Background technique: [0002] High-end wine not only has requirements for the quality of the wine, but also has very delicate requirements for its bottle body and cover body, so that it can be matched. The existing cover body materials generally guarantee plastic, aluminum, metal, etc., and the metal material is due to its shape processing. It is generally not often used due to limitations. At present, most of the injection-molded caps are sprayed with metallic paint, so that from the appearance, the color is obvious and the quality is relatively good. In the prior art, in order to increase the appearance and feel of the bottle cap, The UV screen printing method is adopted, and the volatile solvent in the traditional ink is replaced by a UV curing agent. Af...

Problems solved by technology

[0003] The existing UV screen printing has a simple structure. Most of the bottle caps are manually placed on the rotating shaft one by one, and then the UV screen printing component is activated to perform silk screen printing on the surface. Screen printing effect, but its work efficiency is low, can not meet the requirements of batch processing and production, in order to meet the needs of batch processing and production, there is also the use of automated production and processing, but its price is expensive, the cost is high, and the scope of use is narrow, especially The picking mechanism needs to be replaced according to different bottle caps, and its versatility is poor, so it cannot meet the requirements of small batch processing and production. Moreover, after UV silk screen printing, most of the bottle caps are fed through the material receiving box after blanking. Afterwards, it needs to be sorted manually to meet the loading requirements, thus affecting the process of automated production
