Ink cartridge structure for screen or metal printing equipment

Abstract

The invention is an ink cartridge structure for screen or metal printing equipment. The screen printing equipment is provided with a refillable or internally-replaceable cartridge; the cartridge is internally filled with printing silver paste or various printing inks; and a cartridge ink output mechanism is provided. The ink cartridge structure for the screen or metal printing equipment can enablethe screen printing equipment to be able to control the printing silver paste or ink output amount of the printing ink more accurately and make the quality of printing finished products more stable and uniform, and has an effect of improving printing qualified rate.

Description

technical field [0001] The invention relates to an ink box structure used in screen printing equipment or metal printing equipment, belonging to the technical field of metal printing or screen printing, in particular to an ink box structure used in screen printing equipment. Background technique [0002] Screen printing has been widely used in general livelihood industries or high-tech industries. Whether it is used for processing flat printing, such as acrylic board, button film, aluminum plate, glass, and transfer paper, etc., or for processing curved surface printing, such as plastic bottles, barrels, bats, container bottles, etc.; Even the high-precision printing required in the optoelectronic industry, such as glass plate printing for liquid crystal displays, light guide plates, circuit boards, etc., all show that screen printing technology is extremely important in today's printing field. [0003] The general printing method of screen printing is to configure a scrape...

Problems solved by technology

[0004] However, in traditional printing, the silver paste or ink is pre-placed on the screen, and then the squeegee is used to push the silver paste or ink back and forth. Users cannot know the degree of silver paste or ink on the screen or metal The remaining amount, when the silver paste or printing ink is about to be used up, its falling speed will be much lower than the state when it is covered with silver paste or printing ink, which makes it difficult to control the qualified rate of printed products in this state, that is, if Figure 14 An enlarged partial view of the printed product shown, which has severe ups and downs

Furthermore, in the traditional squeegee printing technology, the silver paste or printing ink is exposed to the atmosphere. In the continuous printing process, the viscosity of the silver paste or printing ink will continue to increase due to the long exposure time. Change, if the speed of the squeegee moving mode is not changed, the traditional printing cannot confirm that the amount of ink is enough for each printing, which will reduce the pass rate of printing quality and cause the loss of printing cost

[0005] The traditional printing squeegee is usually made of soft materials such as rubber or plastic that are in contact with the screen or metal plate. The hardness of the material ranges from 50 to 90 on the Shaw scale. Although the hardness ranges from low to high, it is still an elastic colloid. In the process of traditional printing, the printing angle will still change continuously due to the adjustment of printing parameters such as printing pressure, that is, Figure 16 As shown, the contact surface between the scraper and the screen will be curved, resulting in the inability to accurately control the amount of ink printed each time, reducing the stability and uniformity of printing quality, and increasing printing costs
