Description

Technical Field

[0001] The utility model specifically relates to the technical field of dust prevention for screen printing, in particular to an environmentally friendly dust prevention device for screen printing. Background Art

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

[0003] When the conventional screen printing device is working, the printing device is directly exposed to the air. Thus, during printing, dust in the air will adhere to the printed workpiece through the printing device, which will cause incomplete printing of the workpiece and result in the appearance of waste products.

[0004] After searching, Chinese patent publication number CN202222734606.0 discloses a dust-proof device for color screen printing; comprising a workbench, the top of the workbench is fixedly connected to a support frame, one side inner wall of the support frame is fixedly connected to a printing mechanism, both sides of the support frame are provided with a second slide groove, the inside of the second slide groove is movably connected to a baffle, and the baffle is in contact with the workbench, one side of the baffle is fixedly connected to a rack, both sides of the support frame are fixedly connected to two fixed blocks, a threaded rod is movably connected between the two fixed blocks, one end of the threaded rod passes through one of the fixed blocks and is fixedly connected to a gear, and the gear is meshed with the rack;

[0005] The structure in the above patent seals the working environment of the printing device through the baffle and the cover to prevent external dust from entering the working environment of the printing device. However, during operation, the dust in the working environment may also affect the printing.

[0006] In view of the above situation, we provide an environmentally friendly dust-proof device for screen printing. In this device, a dust-proof component is arranged on one side of the workbench. When the printing device is printing on the tooling on the workbench, the splashes generated during printing are effectively extracted by the suction hood through the negative pressure machine. During the extraction process, the dust inside the frame body can also be effectively extracted to prevent the dust from adhering to the tooling and affecting the printing. The extracted dust enters the adsorption tube, and the dust in the adsorption tube is effectively flushed by the clean water in the water tank to clean the adsorption tube. Since the frame body is open, the external dust may enter the interior of the frame body, so it is effectively discharged through the exhaust fan installed on the top of the frame body.
