Description

Technical Field

[0001] This utility model relates to the technical field of decorative paper processing equipment, and belongs to a double-sided drying device for decorative paper. Background Technology

[0002] In the production process of decorative paper, in order to improve product quality, avoid printing problems, and facilitate subsequent storage and transportation, it is necessary to dry the printed decorative paper.

[0003] Traditional drying methods mostly employ single-sided drying, such as heating and drying one side of the decorative paper using hot rollers or hot air guns. This method has obvious drawbacks.

[0004] On the one hand, single-sided drying is inefficient, requiring a long time to bring the paper to the required dryness, severely restricting production speed. On the other hand, because decorative paper is only heated and dried on one side, uneven moisture content on both sides can easily occur. During subsequent processing and storage, the paper may curl, deform, or exhibit other defects due to moisture imbalance, affecting product quality. Moreover, as the requirements for printing effects and flatness of decorative paper continue to increase, traditional drying equipment struggles to meet the demands of refined production, failing to guarantee uniform curing of ink during the drying process, potentially causing color deviations and blurred patterns. Furthermore, some existing drying equipment lacks energy efficiency, resulting in high energy consumption, increasing production costs, and hindering the sustainable development of enterprises.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of this utility model.

[0027] See Figure 1-2This application provides a decorative paper double-sided drying device, including a drying chamber 1. The drying chamber 1 has a paper inlet 2 and a paper outlet 3 respectively provided on its two side walls. The drying chamber 1 is divided into a preheating zone 11 and a double-sided drying zone 12 along the paper transport direction. The preheating zone 11 is provided with a preheating component 4 for preheating the paper before it enters the double-sided drying zone 12. The double-sided drying zone 12 is provided with a double-sided drying component 5, which includes an upper drying unit 51 and a lower drying unit 52. The upper drying unit 51 is located above the lower drying unit 52. The rear end of the drying chamber 1 is provided with a paper transport roller group 6.

[0028] See Figure 3 Specifically, the preheating component 4 includes an upper infrared radiation plate 41 and a lower infrared radiation plate 42. The upper infrared radiation plate 41 is located above the lower infrared radiation plate 42. Both ends of the upper infrared radiation plate 41 and the lower infrared radiation plate 42 are provided with end plates 43. The end plates 43 are connected to the drying chamber 1. A first terminal 44 is provided on one side of the end plate 43. The preheating component 4 is used to preheat the paper before it enters the double-sided drying zone 12, thereby improving the drying efficiency.

[0029] See Figure 3 Specifically, both the upper infrared radiation plate 41 and the lower infrared radiation plate 42 are provided with an infrared coating 45. The infrared coating 45 has a high absorption rate, which can enhance the infrared radiation effect and accelerate the paper preheating speed.

[0030] See Figure 3 Specifically, the upper drying unit 51 includes a hot air nozzle array 511, which is disposed on an array plate 512. The array plate 512 has connecting shafts 513 at both ends, which are movably connected to the drying chamber 1. Each nozzle in the hot air nozzle array 511 has a ball joint 514 at its top.

[0031] See Figure 3Specifically, the upper drying unit 51 further includes a connecting frame 515, on which connecting pipes 516 are arranged. One end of each connecting pipe 516 is connected to a connecting pipe 517, and the other end of each connecting pipe 516 is threadedly connected to a threaded collar 518. A spherical groove 519 is formed at the lower end of the threaded collar 518, which engages with a spherical connector 514. The nozzle can rotate freely within a certain range using the spherical connector 514 as a fulcrum, achieving flexible adjustment at multiple angles. Simultaneously, the threaded collar 518 acts as a locking mechanism. When the nozzle is adjusted to the desired angle, rotating the threaded collar 518 tightly presses it against the spherical connector 514 of the nozzle, using friction to firmly fix the nozzle and prevent angle deviation during hot air jetting due to airflow impact or other factors.

[0032] See Figure 3 Specifically, the connecting pipe 517 is connected to a hot air pump 5171 via a connecting hose, and the hot air pump 5171 is located at the top of the drying chamber 1.

[0033] See Figure 1 , 4 Specifically, the connecting frame 515 has sliders 5151 at both ends. The sliders 5151 are movably connected to the sliding grooves 5152 formed on the drying chamber 1. The side wall of the drying chamber 1 has a fixed seat 5153, and the fixed seat 5153 has a telescopic rod 5154. The output end of the telescopic rod 5154 is connected to the sliders 5151. The telescopic rod 5154 provides power to drive the sliders 5151 to move along the sliding grooves 5152, thereby moving the connecting frame 515, changing the position of the connecting pipe 516, and simultaneously changing the position of the threaded collar 518. This causes the actuated joint 514 to deflect, thereby driving the air nozzle array 511 to adjust the jet angle.

[0034] See Figure 3 Specifically, the lower drying unit 52 includes an electric heating plate 521 embedded in the bottom of the side wall of the drying chamber 1, and a second terminal 522 is provided on one side of the electric heating plate 521. The air nozzle array 511 can spray high-temperature hot air downwards, and the lower drying unit 52 can provide stable heat upwards, so that the upper and lower parts work simultaneously to achieve synchronous drying of both sides of the decorative paper.

[0035] See Figure 2 , 3 Specifically, the paper transfer roller group 6 includes an upper transfer roller 61 and a lower transfer roller 62, both of which are movably connected to the drying chamber 1, and each of the upper transfer roller 61 and the lower transfer roller 62 is connected to a corresponding drive motor 63.

[0036] See Figure 1Specifically, the top of the drying chamber 1 is also equipped with an air intake fan 13 and an exhaust fan 14, both of which are located within the double-sided drying area 12. The air intake fan 13 is used to replenish fresh hot air into the chamber, and the exhaust fan 14 promptly discharges humid waste gas, maintaining a good heat exchange environment inside the chamber and improving the drying effect.

[0037] The working principle of this invention is as follows: The printed decorative paper is stably transported from the paper inlet 2 to the paper outlet 3 via the paper transport roller assembly 6. The decorative paper enters the drying chamber 1 from the paper inlet 2 and first passes through the preheating zone 11. The upper infrared radiation plate 41 and the lower infrared radiation plate 42 of the preheating assembly 4 preheat the paper. The paper then enters the double-sided drying zone 12. The upper drying unit 51 and the lower drying unit 52 of the double-sided drying assembly 5 work simultaneously. The hot air nozzle array 511 sprays high-temperature hot air downwards, and the electric heating plate 521 provides heat upwards. The paper transport roller assembly 6 ensures stable paper transport. The dried paper is then sent out from the paper outlet 12, completing the double-sided drying process. The intake fan 13 replenishes the chamber with fresh hot air, and the exhaust fan 14 promptly discharges humid waste gas, maintaining a good heat exchange environment inside the chamber and improving the drying effect.

[0038] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
