Description

Technical Field

[0001] The utility model relates to the field of drying devices, in particular to a drying device for interior decoration film printing. Background Art

[0002] In the process of producing automobile interior film, black masking ink is used to apply and print the interior film, so as to achieve the effect of opacity. The interior film applied with masking ink needs to be dried. The existing drying process is mainly carried out by hot air circulation in a drying box. For example, the Chinese utility model type patent with the public document number: CN213767789U discloses a drying device for printing film production. The utility model has a simple structure and is easy to use. It increases the utilization efficiency of heat energy in the drying device, ensures that the heat energy in the drying device is maximized, effectively reduces energy consumption, makes the drying of the printed film more energy-saving, ensures that the drying of the printed film is more comprehensive, avoids incomplete drying of the printed film, and makes the drying more efficient.

[0003] However, the material of the interior film is thin and light. When the hot air is used to dry the interior film, the interior film is prone to wrinkles, and the ink on the interior film is prone to gather and flow under the push of the airflow, which makes the ink applied on the interior film unevenly distributed, affecting the light transmission effect. At the same time, the principle of air-heat drying is mainly to evaporate the water vapor in the ink through high temperature. After the water vapor in the closed drying box evaporates, it still remains in the box, and the humidity in the box increases. The hot air flow in the box is circulated through the second air pipe and the filter plate, and the water vapor is absorbed. However, a large amount of hot air that has not contacted the printed film will also be absorbed by the second air pipe, resulting in a large amount of waste of the hot air flow heated by the electric heating wire. Finally, the temperature in the box is high, more electricity is consumed, but the drying effect on the product is average, so it needs to be improved. Utility Model Content

[0004] The main purpose of the utility model is to provide a drying device for interior film printing, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

During the drying process of the interior decoration film, wind heat drying is avoided, and a high flow rate of airflow is avoided to blow the interior decoration film, causing the ink on the film to move, resulting in uneven distribution of the ink and affecting the light transmission effect.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The upper electric heating plate 9 and the lower electric heating plate 10 can move up and down by rotating the No. 1 screw 11. Guide rods 13 are arranged on both sides of the upper electric heating plate 9 and the lower electric heating plate 10. The upper electric heating plate 9 and the lower electric heating plate 10 are restricted by the guide rods 13 so that the upper electric heating plate 9 and the lower electric heating plate 10 can only move up and down, thereby adjusting the height so that the interior decoration film is in the narrow space between the upper electric heating plate 9 and the lower electric heating plate 10, which is convenient for quickly heating the interior decoration film.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, a No. 1 support plate 3 is fixedly connected to the bottom plate 1 at one side of the drying box 2, a No. 1 driving roller 4 is rotatably connected between the No. 1 support plate 3, a No. 2 support plate 5 is fixedly connected to the bottom plate 1 at the other side of the drying box 2, a No. 2 driving roller 6 is rotatably connected between the No. 2 support plate 5, the drying box 2 is located between the No. 1 driving roller 4 and the No. 2 driving roller 6, a No. 1 slide bar 16 is movably installed in the sliding sleeve 15, the No. 1 slide bar 16 is fixedly connected to the bottom plate 1, screw holes are provided at positions corresponding to the No. 2 screw 17 and the No. 1 screw 11 on the adjusting plate 21 and the drying box 2, a No. 3 support plate 18 is fixedly connected to the bottom plate 1, the two side rod bodies of the No. 2 screw 17 are movably installed with the No. 3 support plate 18 through movable bearings 19, and a No. 2 step 17 is fixedly connected to the bottom plate 1 Stepper motor 20 is installed in the drying box 2, and the output shaft of stepper motor 20 is fixedly connected to one end of screw rod 17. Side mounting plate 8 is fixedly connected to the side position of support plate 5. Stepper motor 7 is movably installed on the side mounting plate 8. The output shaft of stepper motor 7 is fixedly connected to one end of transmission roller 6. Four sleeves 15 are arranged on the bottom of drying box 2. Slide sleeve 15 is movably connected to slide rod 16. When screw rod 17 No. 2 rotates in the screw hole of adjusting plate 21, drying box 2 is reciprocated in a straight line along the direction of slide rod 16. By buffering mobile drying box 2, heated interior decoration film can be removed from drying box 2 in time, and water vapor thereon can be directly dissipated into air, so that the dissipation effect of water vapor is better, thereby improving drying effect.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a gravity roller 26 is movably installed at the side position of the No. 1 driving roller 4, a No. 2 slide bar 22 is fixedly connected to the bottom plate 1 at the side position of the No. 1 support plate 3, a moving block 24 is movably installed on the No. 2 slide bar 22, a connecting plate 25 is fixedly connected to the outer position of the moving block 24, the gravity roller 26 is rotatably connected between the connecting plates 25, a baffle 23 is fixedly connected to the upper end of the No. 2 slide bar 22, the No. 1 driving roller 4 and the No. 2 driving roller 6 are of the same height, so that the interior decoration film passes through the drying box 2 in parallel, to prevent the ink from moving to the side when the interior decoration film is skewed, thereby causing uneven ink distribution, the gravity roller 26 squeezes the interior decoration film by its own gravity, so that the interior decoration film remains taut, thereby maintaining the parallel transmission state of the interior decoration film to avoid wrinkles.

[0024] The first transmission roller 4 and the second transmission roller 6 are connected to each other, and the second transmission roller 6 is connected to the first transmission roller 4 and the second transmission roller 6 is connected to each other, so that the ink on the film body is not affected by gravity and high-speed airflow, and the ink on the film body is not evenly distributed. The electric heating plate 10 rotates the No. 1 screw 11 to adjust the height of the upper electric heating plate 9 and the lower electric heating plate 10, so that the interior film is in the narrow space between the upper electric heating plate 9 and the lower electric heating plate 10. By reducing the space, the interior film is easy to heat up and heat quickly. The No. 2 stepper motor 20 is started to rotate the No. 2 screw 17, and the drying box 2 is pulled to move back and forth slowly on the No. 1 slide bar 16 through the adjustment plate 21, so that the interior film is between the upper electric heating plate 9 and the lower electric heating plate 10. It is heated in a small space, and then the drying box 2 moves. When the water vapor evaporated by the ink on the interior film dissipates outward, it avoids being hindered by the drying box 2, making it easy for the water vapor to dissipate and not easy to gather in the drying box 2, thereby improving the drying effect. When this section of the interior film is dried, the No. 1 stepper motor 7 is started and the No. 2 transmission roller 6 is rotated. After this section of the interior film is stored, the new interior film is pulled to the position between the No. 1 transmission roller 4 and the No. 2 transmission roller 6, and the No. 1 stepper motor 7 is paused again, and then the drying box 2 continues to dry.
