Cosmetic bottle silk-screen printing curing device and method

Abstract

The invention relates to the field of cosmetic bottle surface pattern printing, in particular to a cosmetic bottle silk-screen printing curing device. The device comprises a curing rack, a rotary conveying mechanism and a UV curing mechanism, wherein the rotary conveying mechanism and the UV curing mechanism are fixed to the curing rack; a feeding port of the rotary conveying mechanism is connected with a discharging port of a printing device, a discharging port of the rotary conveying mechanism is connected with a feeding port of a discharging device, and the rotary conveying mechanism is connected with the output end of the UV curing mechanism; the rotary conveying mechanism is used for driving cosmetic bottles to rotate and conveying the cosmetic bottles to a discharging station; and the UV curing mechanism is used for curing ink on the surfaces of the cosmetic bottles. According to the device, through arranging the rotary conveying mechanism, full silk-screen printing curing of thecosmetic bottles is guaranteed, and the cosmetic bottle curing quality is improved.

Description

technical field [0001] The invention relates to the field of cosmetic bottle surface pattern printing, in particular to a cosmetic bottle screen printing curing device and method. Background technique [0002] Screen printing refers to using a screen as a plate base and making a screen printing plate with graphics through a photosensitive plate-making method. Screen printing consists of five major elements, screen printing plate, squeegee, ink, printing table and substrate. Use the basic principle that the graphic part of the screen printing plate can pass through the ink, and the non-graphic part of the mesh cannot pass through the ink. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part on the screen printing plate with a scraper, and move towards the other end of the screen printing plate at a constant speed, and the ink is moved by the scraper from the image and text during the movement. Part of the mesh is extrud...

Problems solved by technology

[0004] The existing cosmetic bottle surface printing technology has the following deficiencies: 1. When the cosmetic bottle is positioned and transported, the cosmetic bottle in the fixture block is first grasped and moved up through the vertical conveying device; and then passed through the horizontal conveying device Drive the cosmetic bottle to move in a straight line to the next station for processing; when using a linear conveying device, driving devices in both horizontal and vertical directions are required to realize the advancement and up and down movement of the cosmetic bottle, resulting in an increase in the number of driving devices; at the same time , the driving device in two directions requires the control system to control the two driving motors, which increases the complexity of the control system

2. When scratching the surface of the cosmetic bottle, first use the positioning fixture to position the cosmetic bottle; then the driving device drives the cosmetic bottle to rotate, and the fixed screen printing frame is in contact with different positions on the outer surface of the cosmetic bottle. The horizontal scraper head above the screen printing screen frame moves back and forth to scrape the ink in the screen printing screen frame to different positions on the outer surface of the cosmetic bottle; when scraping the surface of the cosmetic bottle, it is necessary to rotate the cosmetic bottle and move the horizontal scraper head two times. There are many steps to scrape the surface of the cosmetic bottle, which is not conducive to the rapid scraping of the surface of the cosmetic bottle; at the same time, the scraper head is placed horizontally, and its scraping parts are at the same height, so it can only scrape the same height on the surface of the cosmetic bottle. Scraping; when the inclined surface of the cosmetic bottle needs to be scraped, the horizontally placed scraper head with the same height of the scraping part cannot be scraped, thereby reducing the adaptability of the scraping mechanism

3. When curing the cosmetic bottle after screen printing, the cosmetic bottle is first transported to the positioning fixture for positioning, and then the UV curing mechanism located above the fixture cures the cosmetic bottle; while the cosmetic bottle is in the positioning fixture Part of the screen printing is placed face down and is in contact with the surface of the positioning jig, and the light generated by the UV curing mechanism above the jig cannot irradiate its surface; resulting in insufficient curing of the part of the screen printing placed on the surface of the cosmetic bottle, and then Affect the curing quality of cosmetic bottles
