It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] See also Figures 1 to 4In the practical embodiment, a water transfer printing paper energy-saving drying device is provided. The two sides of the device are respectively provided with an unwinding machine and a winding machine for paper rolls. The prior art of the document is mentioned as background technology, so no excessive explanation is given here. It includes a heating frame shell 1 and two positioning guide devices symmetrically fixed on both sides of the heating frame shell 1. The side walls of the heating frame shell 1 are connected and provided with air inlets 2. The two air inlets 2 are fixedly connected with air inlets 3. A heating mechanism is provided in the heating frame shell 1. The inner walls of the upper and lower ends of the heating frame shell 1 are evenly provided with air outlets 4. When the paper enters the heating frame shell 1, the two air inlets 3 are started to work at the same time to guide the airflow into the heating frame shell 1. At the same time, the heating mechanism heats the airflow, and the hot air is blown out from the air outlet 4 to dry both sides of the water transfer printing paper at the same time. The drying effect is good, and the structure only needs two air inlets 3, which is more energy-saving and has a low manufacturing cost.

[0023] The positioning guide device includes a concave shell 5 fixed on the side wall of the heating frame shell 1, a handwheel rod 6 is inserted and rotatably connected to one side of the concave shell 5, one end of the handwheel rod 6 extends to the lateral end of the concave shell 5 and is fixedly connected to a rotating rod 7, and two active bevel gears 8 are fixedly connected to the rotating rod 7. The inner walls of the two vertical ends of the concave shell 5 are rotatably connected to a bidirectional screw rod 9 through a bearing sleeve, and the upper end of the bidirectional screw rod 9 is fixedly connected to a driven bevel gear 10 meshing with the active bevel gear 8. Two symmetrically arranged nut blocks 11 are threadedly connected to the bidirectional screw rod 9, and the front side walls of the two nut blocks 11 are hingedly connected to two symmetrically arranged rocker arms 12. Slide openings 13 are provided on the front sides of the two vertical ends of the concave shell 5, and both ends of the front sides of the two vertical ends of the concave shell 5 are hingedly connected to two symmetrically arranged adjustment frames 14. The rods 12 all pass through the sliding openings 13 and are respectively hingedly connected to the two adjustment frames 14. The two groups of adjustment frames 14 are rotatably connected to two laterally arranged guide rollers 15 through a rotating shaft. When the paper enters the heating frame shell 1, it first passes between the two groups of guide rollers 15, and then the handwheel rod 6 is rotated to drive the rotating rod 7 to rotate. Since the two active bevel gears 8 are respectively meshed with the two driven bevel gears 10, the two bidirectional lead screws 9 are driven to rotate synchronously. Since the bidirectional lead screws 9 are respectively threadedly connected to the two nut blocks 11, at this time, the two nut blocks 11 are forced to move toward each other, thereby pulling the two swing rods 12 to swing, thereby driving the two adjustment frames 14 to swing, so that the two guide rollers 15 clamp the paper, and the paper can be positioned and guided for transportation, preventing the paper from touching the heating frame shell 1 and avoiding damage to the paper.

[0024] like Figure 2As shown: the heating mechanism includes an electric heater 16 and two electric heating tubes 17. The electric heater 16 is fixed on the upper side of the heating frame shell 1. The two electric heating tubes 17 are respectively fixed on the inner walls of the upper and lower ends of the heating frame shell 1. The electric heater 16 is electrically connected to the two electric heating tubes 17. When the electric heater 16 is started, the two electric heating tubes 17 are heated, thereby heating the air in the heating frame shell 1 to improve the drying efficiency.

[0025] like Figure 4 As shown: a through hole is opened on the side wall of the concave shell 5, and the through hole is rotatably connected to the handwheel rod 6 through a bearing member, so as to facilitate the rotation of the handwheel rod 6.

[0026] like Figure 4 As shown: the inner wall of the transverse end of the concave shell 5 is rotatably connected to the outer wall of the rotating rod 7 through the bearing sleeve 18, so that the rotation of the rotating rod 7 is more stable.

[0027] like Figure 3 As shown, the inner walls on both sides of the sliding opening 13 are frictionally connected with the side walls on both sides of the swing rod 12, so that the swing of the swing rod 12 is more stable.

[0028] like Figure 2 As shown: a dust filter 19 is fixedly connected to the inner wall of one end of the air inlet 2 away from the heating frame shell 1 to prevent dust from being blown onto the water transfer printing paper.

[0029] Working principle: When the paper enters the heating frame shell 1, it first passes between the two sets of guide rollers 15, and then the hand wheel rod 6 is turned to drive the rotating rod 7 to rotate. Since the two active bevel gears 8 are respectively meshed with the two driven bevel gears 10, the two bidirectional screw rods 9 are driven to rotate synchronously. Since the bidirectional screw rods 9 are respectively threadedly connected with the two nut blocks 11, at this time, the two nut blocks 11 are forced to move toward each other, and then the two swing rods 12 are pulled to swing, and then the two adjustment frames 14 are driven to swing, so that the two guide rollers 15 clamp the paper, which can position and guide the paper transportation, prevent the paper from touching the heating frame shell 1, and avoid damage to the paper;

[0030] When the paper enters the heating frame shell 1, the two air inlets 3 are started to work at the same time to guide the airflow into the heating frame shell 1. At the same time, the electric heater 16 is started to heat the two electric heating tubes 17, thereby heating the air in the heating frame shell 1 to improve the drying efficiency. The hot air is blown out from the air outlet 4 to dry both sides of the water transfer printing paper at the same time, with good drying effect. In addition, the structure only needs two air inlets 3, which is more energy-saving and has low manufacturing cost.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
