Technical Field

[0001] The utility model relates to the technical field of drying devices for screen printing machines, in particular to a drying device for screen printing machines. Background Art

[0002] A screen printer is a tool for printing text and images. Its working principle is: the printed text and images are made into a printing plate, installed on a printing machine, and then the machine applies ink or solder paste to the places with text and images on the printing plate, and then directly or indirectly transfers them to paper, non-woven fabrics, metal plates, plastics, leather, wood boards, glass, ceramics or other printing substrates, thereby printing out printed products that are the same as the printing plate. During the screen printing process, the materials need to be heated and dried. The existing technology mostly uses heating rods to directly dry the materials. The hot air in the drying box flows slowly, the temperature distribution is uneven, and the distance between the electric heating rod and the workpiece material on the conveying mechanism cannot be flexibly adjusted according to the height of the material. There are problems such as uneven heating and low drying efficiency, which urgently need to be improved. Utility Model Content

[0031] Embodiment, a drying device of a screen printing machine, such as Figure 1-Figure 4As shown, it includes a bracket 1, a conveyor belt 21 with meshes 22 on the surface, a conveying mechanism 2 arranged on the bracket 1 for conveying materials and including the conveyor belt 21, a drying hood 3 located above the conveying mechanism 2 and provided with a transparent observation window 14 on one side and baffles 15 on both sides, a moving ring 4 located in the drying hood 3 and provided with a slide groove 41 on the inner wall, a driving motor 5 fixedly provided on the top, a gear 6 slidably connected in the slide groove 41 and a uniform wind table 8 fixedly provided on the bottom, and a gear 2 7 fixedly connected to the output end of the driving motor 5 and meshing with the gear 1 6, wherein the uniform wind table 8 is hollow inside and a plurality of air holes 81 are evenly provided on the bottom, and a through groove 16 is provided at the bottom of the baffle 15, which is used to drive the moving ring 4 to move up and down, including rotating a worm 91 arranged on the inner wall of the top of the drying hood 3, and evenly rotating three worm wheels 92 connected to the outer side of the circumference of the worm 91. , a moving component 9 having an L-shaped rod 93 at one end fixedly connected to a worm gear 92 and a connecting rod 94 at the other end, and a connecting rod 94 hinged to a moving ring 4, wherein a base 13 is provided on the top of the drying hood 3, the worm gear 92 is rotatably connected to the base 13, the worm gear 92 is meshed with the worm 91, and the line connecting the center of the worm gear 92 and the center of the moving ring 4 is perpendicular to the moving ring 4; a wind supply component 10 for supplying air to the uniform wind table 8 includes a blower 100, an electric heater 101 located at the front end of the blower 100, and an air inlet pipe 102 connected to the outlet of the electric heater 101 at one end and rotatably connected to the uniform wind table 8 at the other end; a tail gas collection component 11 for collecting tail gas includes an exhaust fan 110, an air outlet pipe 111, and an tail gas filtering mechanism 112 with an air outlet 113; a moving motor 12 for driving the worm 91 to rotate, and a transparent observation window 14.

[0032] The working principle is as follows: firstly, the material is placed on the conveyor belt 21, and the conveyor belt 21 passes the material through the through slot 16 into the drying hood 3, and the blower 100 is started. The blower 100 generates wind which is heated by the electric heater 101 and then supplied to the uniform wind table 8 through the air inlet pipe 102. The hot wind is evenly blown toward the material below through the air holes 81 at the bottom of the uniform wind table 8.
