Description

Technical Field

[0001] This utility model relates to the field of paint coating quick-drying technology, and in particular to an ultrasonic paint coating quick-drying device. Background Technology

[0002] Paint coating is a common process for surface treatment of materials such as wood and metal. Especially in the production of wood products, the quick-drying effect after coating has an important impact on improving production efficiency and product quality. Traditional paint coating drying methods mainly rely on natural air drying or the use of drying equipment, but these methods have certain shortcomings in terms of drying efficiency, energy consumption, and heating uniformity. Utility Model Content

[0003] The purpose of this invention is to solve the problem that in traditional drying devices, uneven hot air flow, low energy efficiency, and slow heating speed often lead to uneven paint drying or excessively long drying processes, which in turn affect production efficiency and product surface quality.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] An ultrasonic paint coating quick-drying device includes a drying unit. A conveying device is located at the lower end of the drying unit, and a wooden board is placed at the upper end of the conveying device. The drying unit includes two fixed frames, and a housing is located at the upper end of each fixed frame. A blower is located at the upper end of the housing, and the output end of the blower is connected to a heating chamber. An air supply pipe is connected to the heating chamber, and the output end of the air supply pipe is fixedly connected to the top of the housing. Several fans are installed at two opposite ends inside the housing, and a circulating exhaust fan is located on one side of the top of the housing. When the fans are turned on, they create air convection circulation, accelerating the movement of hot air. The circulating exhaust fan then reintroduces the circulated hot air into the heating chamber to reduce energy consumption. The bottom of the chamber is equipped with a serpentine heating tube, and multiple fans are installed inside the chamber to create air convection circulation. The fans accelerate the flow of hot air, improving the heat transfer efficiency within the chamber and further enhancing the drying efficiency. The airflow convection helps to evenly heat the surface of the wood board, accelerating the paint drying process. The circulating exhaust fan extracts the heated air and reintroduces it into the heating chamber. This design effectively reduces energy consumption and improves the energy utilization rate of the equipment. The serpentine heating tube at the bottom of the chamber helps to stabilize heating and ensure that the wood board is heated evenly. The serpentine heating tube design prevents heat from concentrating in one place, thus making the temperature of the entire drying area more uniform and ensuring better paint drying results.

[0006] Furthermore, the conveying device includes a support leg, with crossbars on both sides of the upper end of the support leg, a transmission device at the upper end of the support leg, and a fixed base at the bottom of the transmission device.

[0007] Furthermore, the transmission device includes a rotating motor, with several rotating rollers rotatably connected to the crossbar at the upper end of the rotating motor. Two sprockets are provided on one side of each rotating roller. The first rotating roller and the rotating motor are connected to the sprockets via a motor connecting chain. The rotating rollers are connected to each other via sprockets and transmission chains. The rotating motor effectively transmits power to multiple rotating rollers through the sprockets and chains, ensuring smooth operation during the conveying process. Through the synchronous transmission of the chain, multiple rotating rollers can achieve precise synchronous operation. The rotating rollers are made of ceramic material to ensure uniform heating of the wood board during the drying process.

[0008] Furthermore, the bottom of the conveying device is equipped with a bottom serpentine heating device, which is fixedly connected to the bottom of the crossbar through the fixed base. The bottom serpentine heating device distributes heat evenly, so that the wood board can be heated additionally when passing through the conveying device, which further accelerates the drying process of the paint. Especially before entering the drying chamber, the bottom serpentine heating device can ensure the increase of the surface temperature of the wood, improve the paint adhesion and drying effect.

[0009] Furthermore, the bottom serpentine heating device is equipped with a temperature regulator for real-time monitoring and adjustment of the heating temperature, ensuring the stability and accuracy of the heating process.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Through the linkage design of the dual fan group and the circulating exhaust fan inside the box, a forced convection circulation system is formed, which increases the hot air flow rate. Combined with the distributed heat source layout of the serpentine heating tube, the heat transfer efficiency is significantly improved. The circulating exhaust system can recover waste heat to the heating box for reuse.

[0012] 2. The innovative design adopts a double serpentine heating structure, with a laminar flow hot air curtain in the top box and a contact serpentine heat conduction module integrated in the bottom conveyor belt to form a three-dimensional thermal field coverage. The transmission system achieves synchronous drive of the rotating rollers through a precision sprocket set. Combined with the high temperature resistant design of the ceramic bearings, it ensures that the heating of each area of ​​the board is uniform during the conveying process, effectively eliminating the paint film wrinkling defects commonly found in traditional processes.

[0013] 3. The bottom serpentine heating element is equipped with a temperature regulator, which can monitor and adjust the heating temperature in real time, ensuring the stability and accuracy of the entire heating process. This not only ensures a suitable surface temperature for the wood board but also improves the adhesion and drying effect of the paint, further enhancing product quality. Attached Figure Description

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] Combination Figure 1-4As shown, an ultrasonic paint coating quick-drying device includes a drying device 1, a conveying device 2 at the lower end of the drying device 1, and a wood board 3 at the upper end of the conveying device 2. The drying device 1 includes two fixed frames 11, a box 12 at the upper end of the fixed frames 11, a blower 13 at the upper end of the box 12, a heating box 14 connected to the output end of the blower 13, an air supply pipe 15 connected to the heating box 14, and the output end of the air supply pipe 15 fixedly connected to the top of the box 12. Several fans 16 are provided at both opposite ends inside the box 12, and a circulating exhaust fan 17 is provided on one side of the top of the box 12. When the fans 16 are turned on, they form a gas convection circulation, accelerating the movement speed of the hot air. The circulating exhaust fan 17 reintroduces the circulated hot air into the heating box 14 to reduce the heat. To minimize energy consumption, the bottom of the chamber 12 is equipped with a serpentine heating tube 18, and multiple fans are installed inside the chamber to create air convection circulation. The fans accelerate the flow of hot air, improving the heat transfer efficiency within the chamber and further enhancing drying efficiency. The airflow convection helps to evenly heat the surface of the wood board, accelerating the paint drying process. The circulating exhaust fan extracts the heated air and reintroduces it into the heating chamber. This design effectively reduces energy consumption and improves the energy utilization rate of the equipment. The serpentine heating tube at the bottom of the chamber helps to stabilize heating and ensure that the wood board is heated evenly. The serpentine heating tube design prevents heat from concentrating in one place, thus making the temperature of the entire drying area more even and ensuring better paint drying results.

[0021] The conveying device 2 includes support legs 21, with crossbars 22 on both sides of the upper end of each support leg 21. A transmission device 23 is installed on the upper end of the support leg 21, and a fixed base 24 is installed at the bottom of the transmission device 23. The transmission device 23 includes a rotating motor 231, with several rotating rollers 232 rotatably connected to the crossbars 22 at the upper end of the rotating motor 231. Two sprockets 233 are installed on one side of each rotating roller 232. The first rotating roller 232 and the rotating motor 231 are connected by a motor connecting chain 234 and the sprockets 233 for transmission. The several rotating rollers 232 are connected to each other by sprockets 233 and a transmission chain 235. The rotating motor effectively transmits power to multiple rotating rollers through the sprockets and chains, ensuring smooth operation of the conveying process. Through the synchronous transmission of the chain, multiple rotating rollers can achieve precise synchronous operation. The rotating rollers are made of ceramic material to ensure that the wood boards are heated evenly during the drying process. The bottom of the conveyor device 2 is equipped with a bottom serpentine heating device 4, which is fixedly connected to the bottom of the crossbar 22 through a fixed base 24. The bottom serpentine heating device provides additional heating to the wood boards as they pass through the conveyor device through the even distribution of heat, further accelerating the paint drying process. Especially before entering the drying chamber, the bottom serpentine heating device can ensure the increase of the wood surface temperature, improve paint adhesion and drying effect. The bottom serpentine heating device 4 is equipped with a temperature regulator for real-time monitoring and adjustment of the heating temperature to ensure the stability and accuracy of the heating process.

[0022] Working principle: The blower 13 pressurizes the outside air and sends it into the heating box 14. After being heated, the air forms a high-temperature airflow, which is injected from the top of the box 12 through the air supply pipe 15. Multiple sets of fans 16 on both sides of the box start simultaneously, forming a bidirectional forced airflow. The hot air covers the surface of the wood board 3 from top to bottom in a laminar flow, accelerating heat conduction. The circulating exhaust fan 17 draws the residual heat gas after cooling at the bottom of the box back to the heating box 14, mixes it with the newly injected air, and then heats it again to reduce heat loss. The rotating motor 231 drives multiple sets of rotating rollers 232 to rotate synchronously through the sprocket 233 and the transmission chain 235, which transports the board into the drying device 1. The ceramic rotating rollers can withstand a high temperature of 250℃, avoiding transmission deviation caused by thermal expansion.
