Description

Technical Field

[0001] The utility model relates to the technical field of screen printing equipment, in particular to a four-sided turntable screen printing equipment. Background Art

[0002] Screen printing uses a silk screen as a base and a photosensitive platemaking process to create a screen printing plate with an image or text. Screen printing consists of five key elements: the screen printing plate, squeegee, ink, printing table, and the substrate. Printing is based on the principle that the mesh holes in the image area of ​​the screen printing plate are permeable to the ink, while the mesh holes in the non-image area are impermeable to the ink. During printing, ink is poured into one end of the screen printing plate. A squeegee is used to apply pressure to the inked area of ​​the screen while moving at a constant speed toward the other end of the screen printing plate. As the squeegee moves, the ink is squeezed through the mesh holes in the image area onto the substrate.

[0003] In the production process of alloy resistors, screen printing equipment is needed to screen print the resistors. In the existing resistor semi-automatic screen printing machine, usually one operator and one machine manually arrange the screen printing object and place it into the screen printing machine for printing. After the screen printing is completed, the alloy resistor material strip is taken out. This method requires the previous screen-printed alloy resistor material strip to be taken out before the next alloy resistor material strip can be clamped. The waiting time is long, which not only reduces work efficiency but also makes it inconvenient to clean the alloy resistor material sheet before screen printing. In order to improve the screen printing quality and efficiency of alloy resistor material sheets, we propose a four-sided turntable screen printing equipment. Utility Model Content
