When the paper needs to be dried after printing, the fan will transport the extracted gas through the corrugated connecting tube to the inside of the spiral cavity tube for heating treatment by the heating rod. After the transported air is heated, it is transported to the inside of the cavity tube again through another corrugated connecting tube. The hot air entering the cavity tube heats the cavity tube, thereby quickly drying the paper printed on the cavity plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a flat drying structure 2 is provided inside the screen printing machine structure 1, and the flat drying structure 2 includes a base frame 201 with a through hole, and the overall shape of the base frame 201 is an "L" structure. When the overall shape of the above-mentioned parts is an "L" structure, it not only reflects the practicality of the installation and arrangement of the above-mentioned parts, but also reflects the space reserved after the above-mentioned parts and the cavity plate 2019 are fixedly installed. When the overall shape of the above-mentioned parts is an "L" structure, the force support and the through-connectivity of the installation and arrangement of the above-mentioned parts are reflected, and the base frame 201 is fixedly installed on the placement table 102, and a connecting seat 202 is fixedly installed on the base frame 201. The connecting seat 202 is The body shape is arranged in an "open" structure. When the overall shape of the above-mentioned parts is arranged in an "open" structure, the openness above the surface of the above-mentioned parts is reflected, and the fixed connectivity of the above-mentioned parts is also reflected. When the overall shape of the above-mentioned parts is arranged in an "open" structure, the axial symmetry of the installation of the above-mentioned parts is reflected. A groove 203 is opened above the surface of the connecting seat 202, and a guide through groove 204 is opened through the inside of the groove 203. At the same time, guide sliding grooves 205 are opened on both sides of the inner wall of the groove 203, wherein a group of guide sliding grooves 205 are opened. When a group is opened using the above-mentioned structure, the stable driving sliding of the bearing seat 209 is guaranteed.

[0047] Furthermore, the above scheme has a rotating motor 206 fixedly mounted on the placing table 102 below the base frame 201, and the output end of the rotating motor 206 extends through the through hole above the base frame 201, and at the same time, a rotating connecting rod group 207 is fixedly mounted on the output end of the rotating motor 206, and a bayonet 208 is rotatably mounted on one end of the rotating connecting rod group 207, and one end of the bayonet 208 passes through the guide groove 204 and is fixedly connected to the bottom of the bearing seat 209 with the sliding bar 2010, wherein the above-mentioned components constitute a driven sliding motion, and the driving sliding motion constituted by the above-mentioned components can effectively change the sliding interval distance of the bearing seat 209 during the driving sliding operation, and the synchronous adjustment of the rotating rod 2011 can be effectively driven by changing the sliding driving distance of the bearing seat 209.

[0048] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the above scheme is further, the bearing seat 209 is slidably arranged on the connecting seat 202 through the sliding bar 2010, and the bearing seat 209 is penetrated by a rotating rod 2011 with rotation adjustment, and at the same time, one end of the rotating rod 2011 is fixedly connected to the contact rod 2013 through the connecting plate 2012, and the contact rod 2013 is slidably connected to the sliding reversing groove 2014, and the sliding reversing groove 2014 is opened on the inner side of the arch plate 2015, and the arch plate 2015 is fixedly installed on the connecting On one side above the seat 202, the sliding reversing groove 2014 is composed of a horizontal straight groove and a curved groove. The sliding reversing groove 2014 composed of a horizontal straight groove and a curved groove can effectively change the rotation direction of the contact rod 2013 and the rotating rod 2011. By changing the rotation direction of the rotating rod 2011, the scraper plate 2018 is prevented from always being above the cavity plate 2019 to affect the normal screen printing of the placed paper or material.

[0049] Furthermore, in the above scheme, a connecting plate 2016 is fixedly installed on the other end of the rotating rod 2011, and a mounting frame 2017 is fixedly installed on the surface of one side of the connecting plate 2016, and a scraper plate 2018 is fixedly installed on the bottom of the mounting frame 2017, a cavity plate 2019 is fixedly installed on the top of the base frame 201, and a vent hole 2020 is opened through the surface of the cavity plate 2019, and a cavity tube 2021 is fixedly installed on the bottom of the cavity plate 2019 through a grid, and one end of the cavity tube 2021 is installed and connected to the other end of the corrugated connecting tube 108 through a connecting tube, and the other end of the other corrugated connecting tube 108 is also embedded and connected with the lower side of the cavity tube 2021 through a connecting tube, wherein the above-mentioned components constitute a driving rotating structure, and when the driving rotating structure constituted by the above-mentioned components is utilized, the driving sliding rotation angle of the scraper plate 2018 is changed, and when the driving sliding rotation angle of the scraper plate 2018 is changed, the normal screen printing processing of placing paper and placing objects is ensured.

[0050] In the above scheme, when the paper needs to be screen printed, the operator manually places the paper on the cavity plate 2019, and controls the fan 106 to form a negative pressure when it is running to transport the extracted gas to the inside of the corrugated connecting tube 108. If the gas entering the inside of the corrugated connecting tube 108 needs to be heated, it passes through the branch pipe 107 and is transported to the cavity tube 2021 through another corrugated connecting tube 108. When the gas does not need to be heated, it is directly discharged through the cavity tube 2021. After the paper is adsorbed and limited, the driving device in the screen printing machine body 101 is used to control the placement table 102 to run upward. At this time, the rotating motor 206 synchronously runs and drives the bearing seat 209 to slide by rotating the connecting rod group 207, the pin 208 and the sliding bar 2010. When the bearing seat 209 slides under force, it drives the rotating rod 2011, the connecting plate 2012, the contact rod 2013, the connecting plate 2016, and the mounting frame 2 017 and the scraper plate 2018 move synchronously. When the scraper plate 2018 moves under force, the placed paper is scraped flat. When the contact rod 2013 contacts the curved groove in the sliding reversing groove 2014, the rotating rod 2011 drives the mounting frame 2017 and the scraper plate 2018 to rotate under force, thereby driving the mounting frame 2017 and the scraper plate 2018 to rotate 90 degrees. At this time, the screen printing equipment in the screen printing body 101 prints the rising paper. When the printed paper needs to be dried, the automatic control valve in the branch pipe 107 is closed at this time, and the heater 109 and the heating rod 105 are controlled to heat the airflow entering the spiral cavity tube 104 and then transport it to the cavity tube 2021. The hot airflow entering the cavity tube 2021 heats the cavity tube 2021, and the heat diffused through the cavity tube 2021 can be used to dry the printed paper.
