Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a lifting and lowering drying device for the production of water transfer printing paper. Background Technology

[0002] Drying equipment refers to a combination of mechanical devices that use certain technical means to dry the surface of objects of moisture or other liquids. It is a device that utilizes heat energy to dry materials with high moisture content; the utilization of heat energy plays a crucial role in the drying process. Water transfer printing paper needs to be dried after production to better facilitate subsequent printing and packaging.

[0003] For example, a drying device for processing water transfer printing paper with application number 201920710693.1 mostly uses a fixed-position drying device to dry water transfer printing paper, which means that water transfer printing paper with different humidity levels is dried at the same distance. The distance cannot be adjusted according to the humidity, which may lead to over-drying or prevent release paper with too much moisture from being fully dried. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting and lowering drying device for water transfer printing paper production in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The two sides of the fixed frame along the length direction are fixedly connected to the drying chamber. Through slots communicating with the through slot in the middle of the fixed frame are opened on both sides of the fixed frame. Paper inlet and paper outlet are opened on both sides of the drying chamber and communicate with the corresponding through slots. Two sets of heating plates are arranged in the drying chamber at the upper and lower parts of the fixed frame. The heating plates can pass through the through slot in the middle of the fixed frame. The two sets of heating plates move vertically towards or away from the fixed frame at the same time. A paper feeding structure is provided in the drying chamber to drive the water transfer printing paper to move from the paper inlet along the fixed frame towards the paper outlet.

[0007] As a further description of the above technical solution:

[0008] The heating plate is fixedly connected to a first connecting frame and a second connecting frame on both sides. A connecting rod is rotatably connected to the middle of the first connecting frame. The free end of the connecting rod is rotatably connected to a slider that moves linearly along the width of the fixed frame. Two sets of guide posts passing through the second connecting frame are fixedly connected inside the drying oven.

[0009] As a further description of the above technical solution:

[0010] The drying box is fixedly connected to the other side of the fixed frame with a limiting plate that contacts both sides of the slider. A second drive motor is fixedly installed on the drying box, and the output shaft of the second drive motor is fixedly connected to a threaded rod that is threadedly connected to the slider.

[0011] As a further description of the above technical solution:

[0012] The fixed frame has mounting grooves with a regular hexagonal cross section on both sides. The paper feeding structure includes a cooperating active roller and a driven roller. The active roller and the driven roller are rotatably installed in the mounting grooves, and the active rollers on both sides rotate synchronously when driven.

[0013] As a further description of the above technical solution:

[0018] The fixed frame has a support plate fixedly connected to both sides of the through groove in the middle along the width direction, and the upper surface of the support plate is flush with the lower surface of the through groove.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, the threaded rod is driven to rotate by the second drive motor, the slider moves toward the fixed frame, and pushes the two sets of connecting rods to rotate outward. The first connecting frame pushes the two sets of heating plates away from the fixed frame to dry the water transfer paper that passes through the through groove in the middle of the fixed frame. Similarly, when the second drive motor reverses, the two sets of heating plates move closer to the fixed frame.

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5This utility model provides a technical solution: a lifting drying device for water transfer printing paper production, including a drying box 1, a fixed frame 12 fixedly connected to the middle of the drying box 1, the two sides of the fixed frame 12 along the length direction being fixedly connected to the drying box 1, and a space left between the two sides of the fixed frame 12 along the width direction and the drying box 1, the two sides of the fixed frame 12 having a hexagonal cross-section of the mounting groove 1201, the two sides of the fixed frame 12 having a through groove 1202 communicating with the through groove and mounting groove 1201 in the middle of the fixed frame 12, the two sides of the drying box 1 having a paper inlet 101 and a paper outlet 102 communicating with the corresponding through groove 1202, the paper inlet 101 having a V-shaped cross-section with the opening facing outward, and the two sides of the through groove in the middle of the fixed frame 12 having a support plate 13 fixedly connected along the width direction, the upper surface of the support plate 13 being flush with the lower surface of the through groove 1202. The water transfer paper is fed into the through slot 1202 through the paper inlet 101. Under the action of the paper feeding structure, it passes through the left mounting slot 1201 and moves towards the through slot in the middle of the fixed frame 12. The water transfer paper continues to move along the surface of the tray 13. The heating plate 6 dries the water transfer paper from the upper and lower surfaces of the through slot. The V-shaped paper inlet 101 and the V-shaped mounting slot 1201 facilitate the smooth feeding and discharging of the water transfer paper.

[0031] Furthermore, such as Figure 1 As shown, a first connecting frame 7 and a second connecting frame 8 are fixedly connected to both sides of the heating plate 6. A connecting rod 10 is rotatably connected to the middle of the first connecting frame 7. A slider 16 is rotatably connected to the free end of the connecting rod 10. A limiting plate 11 that contacts both sides of the slider 16 is fixedly connected to the other side of the drying box 1 and the fixed frame 12. A second drive motor 14 is fixedly installed on the drying box 1. A threaded rod 15 that is threadedly connected to the slider 16 is fixedly connected to the output shaft of the second drive motor 14. Two sets of guide posts 9 that pass through the second connecting frame 8 are fixedly connected inside the drying box 1. The heating plate 6 can pass through the through groove in the middle of the fixed frame 12. The second drive motor 14 drives the threaded rod 15 to rotate. According to the threaded transmission principle, the slider 16 moves toward the fixed frame 12, pushing the two sets of connecting rods 10 to rotate outward. The first connecting frame 7 pushes the two sets of heating plates 6 away from the fixed frame 12 to dry the water transfer paper that passes through the central groove of the fixed frame 12. Similarly, when the second drive motor 14 reverses, it causes the two sets of heating plates 6 to move closer to the fixed frame 12. The drying distance is adjusted according to the humidity of the water transfer paper to avoid over-drying and incomplete drying.

[0032] Specifically, such as Figure 2 and Figure 3As shown, the driving roller 4 and driven roller 17 are rotatably installed in the mounting groove 1201. The driving and driven rollers are rubber rollers, which, under the action of friction, cause the water transfer paper between them to move forward. The first drive motor 2 is fixedly installed on the drying chamber 1. A pulley 5 is fixedly sleeved on the roller shaft of the driving roller 4. The two sets of pulleys 5 are connected by a belt 3. The output shaft of the first drive motor 2 is fixedly connected to the roller shaft of one set of driving rollers 4. The left driving roller 4 is driven to rotate by the second drive motor 2. Under the transmission action of the belt 3 and the pulley 5, the two driving rollers 4 move synchronously, thereby causing the water transfer paper between the driving and driven rollers to move forward from the paper inlet 101 through the left through groove 1202 and mounting groove 1201, the through groove in the middle of the support plate 13 and the fixed frame 12, the right mounting groove 1201 and through groove 1202, and finally out through the paper outlet 102. The drying operation is completed during the process of feeding the water transfer paper into and out of the drying chamber 1.

[0033] Working principle: In use, the second drive motor 14 first drives the threaded rod 15 to rotate. According to the threaded transmission principle, the slider 16 moves towards the fixed frame 12, pushing the two sets of connecting rods 10 to rotate outward. Through the first connecting frame 7, the two sets of heating plates 6 are pushed away from the fixed frame 12 to dry the water transfer paper that has passed through the central groove of the fixed frame 12. Similarly, when the second drive motor 14 reverses, the two sets of heating plates 6 move closer to the fixed frame 12. The drying distance is adjusted according to the humidity of the water transfer paper to avoid over-drying and under-drying. After completing the problem, the second drive motor 2 is started to drive the left active roller 4 to rotate. Under the transmission action of belt 3 and pulley 5, the two active rollers 4 move synchronously, thereby causing the water transfer paper between the main and driven rollers to advance from the paper inlet 101 through the left through groove 1202 and mounting groove 1201, the through groove in the middle of the tray 13 and the fixed frame 12, the right mounting groove 1201 and through groove 1202, and finally be sent out through the paper outlet 102. The drying operation is completed during the process of the water transfer paper being fed into and out of the drying box 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
