[0002] A screen printing machine is a machine that uses a screen printing plate to apply printing. It is a type of printing machine that prints text and images. It is a general term for machines or equipment used to produce printed materials. Screen printing machines are a representative type of printing equipment among stencil printing machines. In addition to silk, the materials used to make screens can also be nylon, copper, steel, or stainless steel wire. They can be divided into flat screen printing machines, curved screen printing machines, rotary screen printing machines, etc.

[0003] For example, the utility model patent with authorization announcement number CN206456954U discloses a printing feeding device for a screen printing machine, which includes a base and a back plate. The lower surface of the back plate is fixedly connected to the upper surface of the base. The upper surface of the base is respectively provided with a feeding conveyor belt and a discharging conveyor belt. The feeding conveyor belt is located to the left of the discharging conveyor belt. The outer surfaces of the feeding conveyor belt and the discharging conveyor belt are respectively fixedly connected with a first guide block and a second guide block arranged at equal intervals.

[0029] Working Principle: In the idle area of ​​this device, all the components mentioned above, which refer to structural parts, are connected. The specific connection methods should refer to the working principle described below, and the connection between each component should be completed in the order of operation. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and will not elaborate on them.
