[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 A low-temperature color printing drying device includes a drying chamber 1 and a conveyor belt 4 disposed on the left side of the drying chamber 1. The right side of the conveyor belt 4 passes through the drying chamber 1 and extends to its exterior. A drying connection component 2 is disposed on the drying chamber 1, and a dustproof connection component 3 is disposed on the drying connection component 2. A controller is fixedly connected to the front of the drying chamber 1.

[0021] The drying connection assembly 2 includes an air pump 21 and a fixed housing 22. The air pump 21 is installed on the top of the drying chamber 1, and the fixed housing 22 is located on top of the air pump 21. The left and right sides of the bottom of the fixed housing 22 are fixedly connected to the top of the drying chamber 1 through support blocks. A connector 23 is fixedly connected to the top of the inner wall of the drying chamber 1. The air pump 21 is connected to the connector 23 through a pipe. Connecting pipes 24 are fixedly connected to the left and right sides of the connector 23 and communicate with it. An air blowing head 25 is fixedly connected to the end of the connecting pipe 24 away from the connector 23 and communicates with it. A solenoid valve 26 is provided on the connecting pipe 24. The left and right sides of the inner wall of the fixed housing 22 are fixedly connected through heating wires 27. A temperature sensor 28 is fixedly connected to the left side of the bottom of the inner wall of the fixed housing 22. A partition 29 is fixedly connected to the bottom of the connector 23. The side of the partition 29 closest to the inner wall of the drying chamber 1 is fixedly connected to the inner wall of the drying chamber 1.

[0022] Low wind speed (0.5-1m / s) allows the ink to initially dry on the surface, forming a slight cured layer. Medium wind speed (1-1.5m / s) accelerates deep drying. At this point, the ink has a certain wind resistance, improving the drying effect and efficiency.

[0023] The dustproof connection assembly 3 includes a dustproof mesh plate 31, which is disposed on the top of the fixed shell 22. The bottom of the dustproof mesh plate 31 is in contact with the top of the fixed shell 22. Fixed grooves 32 are provided on both the left and right sides of the fixed shell 22. Movable iron blocks 33 are disposed inside the fixed grooves 32. The surface of the iron blocks 33 is in sliding contact with the inner wall of the fixed grooves 32. Movable blocks 34 are fixedly connected to the side of the two iron blocks 33 that are far apart from each other. The side of the movable blocks 34 that is far away from the iron blocks 33 passes through the fixed grooves 32 and extends to its outside. A limiting block 35 that works with the dustproof mesh plate 31 is fixedly connected to the top of the movable blocks 34. The side of the limiting block 35 that is close to the dustproof mesh plate 31 is in contact with the dustproof mesh plate 31. A magnet 36 that attracts the iron blocks 33 is fixedly connected to the inner wall of the fixed grooves 32. By setting the magnet 36, the iron blocks 33 are limited, thereby ensuring the stability of the limiting block 35 during use.

[0024] Positioning blocks 37 are fixedly connected to the left and right sides of the bottom of the dustproof mesh plate 31. The top of the fixed shell 22 is provided with a positioning groove 38 that is adapted to the positioning block 37. The bottom of the positioning block 37 passes through the positioning groove 38 and extends into it to contact the inner wall of the positioning groove 38. By setting the positioning block 37 and the positioning groove 38, the stability of the dustproof mesh plate 31 placed on the fixed shell 22 is improved.

[0025] When the dustproof mesh plate 31 needs to be removed, pull the two limiting blocks 35 away from each other. The limiting blocks 35 move the iron block 33 away from the magnet 36 through the moving block 34, so that the iron block 33 and the magnet 36 are separated, and the limiting blocks 35 are separated from the dustproof mesh plate 31. Then, pull the dustproof mesh plate 31 upward. The dustproof mesh plate 31 drives the positioning block 37 to move upward and separate from the positioning groove 38, thus completing the removal.

[0026] The air pump 21, solenoid valve 26, heating wire 27, temperature sensor 28, and conveyor belt 4 are electrically connected to the controller. The control circuit can be easily programmed by those skilled in the art and is common knowledge in the field, so it will not be described in detail here. The temperature sensor 28 transmits the temperature monitored by the heating wire 27 inside the fixed housing 22 to the controller. The controller controls the heating temperature of the heating wire 27 and controls the flow rate of the solenoid valve 26.

[0027] By combining the heating wire 27 with the air pump 21, low-temperature hot air can be generated to avoid high-temperature damage to the material. Combined with the temperature sensor 28 to monitor the temperature in real time, the material is dried in a low-temperature environment of 50-80℃. Moreover, by setting the solenoid valve 26, the two air blowers 25 blow out low and medium air respectively, avoiding the ink from being blown away when drying with strong air. The dustproof mesh 31 can filter the air entering the fixed shell 22, preventing dust particles from entering the drying chamber 1, avoiding contamination of the undried ink, improving the cleanliness and quality of the printed surface. In addition, the dustproof mesh 31 can be disassembled for cleaning periodically, improving the flexibility of use.

[0028] In use, the heating wire 27 is activated, and the temperature inside the fixed shell 22 is sensed by the temperature sensor 28. The controller controls the temperature to ensure it is between 50-80℃. Then, the printing material enters the drying chamber 1 from left to right via the conveyor belt 4. The left solenoid valve 26 is opened one-third, and the right solenoid valve 26 is opened two-thirds. The air pump 21 is activated, so that the gas inside the fixed shell 22 is blown out through the connector 23, the connecting pipe 24, and the two air blowers 25. The air blower 25 on the left blows out a low wind to perform preliminary drying and solidification of the ink (low wind speed range, 0.5-1m / s). The air blower 25 on the right blows out a medium wind to accelerate the drying effect of the ink (medium wind speed range, 1-1.5m / s).

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
