Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a dip-coating double-sided synchronous coating device. Background Technology

[0002] In modern industrial production, double-sided coating technology is widely used in electronics, packaging, new energy and other fields, such as lithium battery separator coating and anti-scratch coating on optical film surfaces. Traditional dip-coating equipment mostly adopts single-sided coating or double-sided step-by-step coating methods, which have problems such as low coating efficiency and uneven coating thickness. Although some equipment can achieve double-sided synchronous coating, it lacks an adaptive pressure adjustment mechanism, making it difficult to adapt to materials of different thicknesses, resulting in unstable coating quality. In addition, the maintenance design of existing equipment is inadequate. The immersion tank is inconvenient to clean, which can easily cause coating liquid residue to corrode the equipment. Key components are difficult to replace, the equipment failure rate is high and the maintenance cycle is long, which seriously affects production efficiency and equipment life. Therefore, there is a need for a double-sided synchronous coating device with efficient coating, adaptive adjustment and convenient maintenance functions to meet the high precision and high reliability requirements of industrial production. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an immersion-coating double-sided synchronous coating device. This device uses a pressing mechanism consisting of a second guide rod, a spring, and a slider, which can automatically adjust the pressure according to the material thickness. When the material thickness fluctuates, the spring compresses or rebounds, ensuring that the pressing roller always applies uniform pressure to the material. This avoids coating defects caused by uneven pressure in traditional mechanical pressing methods, and achieves high-precision double-sided coating.

[0004] This utility model also provides a dip-coating double-sided synchronous coating device, including a base plate, a dyeing tank fixedly connected to the upper middle part of the base plate, a support plate fixedly connected to the upper end of the base plate, the support plate being located on both sides of the dyeing tank, a top plate fixedly connected to the upper end of the support plate, an electric telescopic rod fixedly connected to the lower middle part of the top plate, a pressing mechanism being provided at the telescopic end of the electric telescopic rod, a second support block fixedly connected to the front end of the dyeing tank, a driving mechanism being provided at the upper end of the second support block, and the pressing mechanism including:

[0005] The mounting bracket is located at the lower end of the electric telescopic rod and is fixedly connected to the electric telescopic rod. The mounting bracket is gate-shaped.

[0006] The slide is located inside both ends of the mounting bracket extension;

[0007] A slider is located inside a groove, and the outer surface of the slider is slidably connected to the inner wall of the groove.

[0008] The second guide rod is located inside the slide groove and is in close contact with the slider.

[0009] The pressing roller has its side end fixedly connected to the second guide rod.

[0010] The drive mechanism includes:

[0011] Mounting plate, located at the upper end of the second support block;

[0012] The drive motor is located on the outside of the mounting plate.

[0013] According to the dip-coating double-sided synchronous coating device, a first guide rod is fixedly connected to the upper end of the mounting frame. The outer surface of the first guide rod is slidably connected to the inner wall of the top plate. There are two first guide rods, which are symmetrically distributed on both sides of the electric telescopic rod.

[0014] By adopting the above technical solution, the cooperation between the first guide rod and the top plate ensures that the electric telescopic rod can maintain stability when pushing the mounting frame down, so that the pressing roller can contact the material surface more accurately and improve the coating accuracy and stability.

[0015] According to the dip-coating double-sided synchronous coating device, the pressing roller includes a metal hollow roller, a rubber layer and a Teflon coating. The outer surface of the metal hollow roller is fixedly connected to the rubber layer, and the outer surface of the rubber layer is fixedly connected to the Teflon coating.

[0016] By adopting the above technical solutions, the metal hollow roller provides a certain strength and support, the rubber layer is elastic and can better fit the material surface, and the Teflon coating can prevent the coating liquid from adhering, making it easy to clean and ensuring the coating effect.

[0017] According to the dip-coating double-sided synchronous coating device, the lower end of the slider is rotatably connected to a first rotating shaft, and the outer side of the first rotating shaft is in contact with the groove.

[0018] By adopting the above technical solution, the friction between the slider and the groove can be reduced by the first rotating shaft, so that the slider can slide more smoothly in the groove, thereby ensuring that the pressing roller can better adapt to the undulations of the material surface and always adhere to the material with appropriate pressure, thus improving the uniformity of coating.

[0019] According to the dip-coating double-sided synchronous coating device, a spring is sleeved on the outside of the second guide rod, and the upper end of the second guide rod passes through the top of the slide groove and extends to the upper end of the mounting bracket.

[0020] By adopting the above technical solution, the spring setting enables the pressure roller to adhere to the material surface with uniform pressure. When the material surface is uneven or has thickness variations, the spring can be adaptively adjusted by compression or extension to ensure the stability of the coating pressure and thus ensure the coating quality.

[0021] According to the dip-coating double-sided synchronous coating device, the output end of the drive motor is fixedly connected to a drive roller.

[0022] By adopting the above technical solution, the drive roller rotates under the drive of the drive motor, which is used to pull the material to move in the device.

[0023] According to the dip-coating double-sided synchronous coating device, a drain hole is provided on the right side of the bottom of the dip tank, and a sealing plug is tightly fitted to the inner wall of the drain hole.

[0024] By adopting the above technical solution, a drainage function is provided for the dyeing tank, which makes it convenient to replace the coating liquid or clean the tank when needed.

[0025] According to the dip-coating double-sided synchronous coating device, a first support block is fixedly connected to the rear end of the dip tank, and an unwinding mechanism is provided at the upper end of the first support block.

[0026] By adopting the above technical solution, the unwinding mechanism is used to place the material to be coated, and by cooperating with the driving mechanism, the continuous supply of material is realized.
