Printed material bearing platform for curved surface printing

Abstract

The invention discloses a printed material bearing platform for curved surface printing. The printed material bearing platform comprises a linear guide rail arranged on a substrate, and four sliding seats are sequentially arranged on the linear guide rail from left to right. The second sliding seat and the third sliding seat are movably connected with the substrate through locking assemblies. Thefirst sliding seat and the second sliding seat are connected through an air cylinder, and the third sliding seat and the fourth sliding seat are connected through an air cylinder. A left rotary moduleis arranged on the first sliding seat, and a left bearing wheel set is arranged on the second sliding seat. A right bearing wheel set is arranged on the third sliding seat, and a right rotary moduleis arranged on the fourth sliding seat. A right rotary shaft is connected with a rotary driving mechanism. A printed material actively rotates, the rotating initial position and end position and the taking and placing positions of the printed material can be precisely determined, repeated printing is convenient, and high precision is guaranteed. Feeding is convenient and accurate, the printed material can automatically fall off from a clamp, and taking and placing are convenient; and the printed material bearing platform can adapt to processing of printed materials of multiple specifications.

Description

technical field [0001] The invention relates to a curved screen printing device. Background technique [0002] Curved surface printing refers to the printing of substrates with curved surfaces. In the existing curved surface printing equipment, the substrate is fixed by the movable clamp, so that the substrate moves passively with the movement of the scraper, so as to ensure that the printing speed of the scraper is synchronized with the rotation of the substrate, and the graphics on the screen will be accurate during the printing process. transferred to the substrate surface. [0003] However, in the existing equipment, the substrate is passively rotated, so that the position of the substrate needs to be adjusted each time during multiple printings, which reduces the printing efficiency; the supporting platform of the existing substrate can only be used for a specific size of the substrate , the scope of application is small; it is inconvenient to take and place the exist...
