Description

Technical Field

[0001] The invention relates to the technical field of slit coating, in particular to alkaline resin slit coating equipment. Background Art

[0002] Slit coating technology is a very high-precision coating technology. It uses an extremely fine nozzle and a high-precision coating system to apply viscous liquids or paste materials to specific locations on the product, thereby achieving high-precision, high-efficiency and high-quality coating operations. This technology is suitable for different types of materials, such as glue, paint, ink, acidic liquids, etc., and is widely used in various fields such as medical, electronics, automobiles and aviation.

[0003] Currently, when coating alkaline resin onto an anion exchange membrane, a transmission device is usually used to transport the anion exchange membrane and drive a slot coating die head close to the anion exchange membrane for coating. However, when the alkaline resin inside the slot coating die head is discharged, the instantaneous pressure used to overcome the static friction of the alkaline resin inside the slot coating die head is relatively high, resulting in a "thick head" phenomenon at the beginning of coating. The thickness of the area of ​​the anion exchange membrane surface where the coating is just started is higher than that of the area where the coating is continued subsequently, thereby affecting the quality of the alkaline resin coating. In the subsequent process, secondary inspection is required and the areas where the coating thickness is too high are cut, resulting in a waste of resources. To this end, we provide an alkaline resin slot coating device to solve the above problems. Summary of the Invention

[0030] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0032] As described in the background technology, when the alkaline resin inside the slit coating die is discharged, the instantaneous pressure used to overcome the static friction of the alkaline resin in the slit coating die is relatively high, which leads to a "thick head" phenomenon at the beginning of coating, so that the thickness of the area where the anion exchange membrane surface is first coated is higher than the area where the coating is continued subsequently, thereby affecting the coating quality of the alkaline resin, and requiring subsequent secondary inspection and cutting of the areas where the coating thickness is too high, resulting in waste of resources. For this purpose, this embodiment provides an alkaline resin slit coating device, which adopts a slit coating method to coat the alkaline resin on the surface of the anion exchange membrane, and can reel up the anion exchange membrane coated with the alkaline resin, and can detect the coating thickness, and at the same time scrape off the excess alkaline resin, and can squeeze the anion exchange membrane coated with the alkaline resin as needed, so that the anion exchange membrane coating is more uniform.

The two groups of universal wheels 19 are symmetrically arranged with the mid-vertical line of the slit coating device body 1 as the symmetry axis. By arranging the universal wheels 19, the alkaline resin slit coating device can be easily moved.

[0034] The bottom surface of the slit coating device body 1 is threadedly connected with four leveling legs 20 for leveling the alkaline resin slit coating device. By rotating the leveling legs 20, the alkaline resin slit coating device can be leveled, thereby improving stability during use.

At the same time, fix the anion exchange membrane on the winding roller 14, then connect the power supply of the water pump 6 and start it to generate suction, thereby extracting the alkaline resin in the storage box 5, so that the alkaline resin enters the slit coating die body 7, and the delivered anion exchange membrane is sucked out. The anion exchange membrane is coated, and the first servo electric cylinder 8 is powered on and started, and its telescopic end is extended and retracted, which can drive the support plate 9 to move back and forth, thereby driving the slit coating die body 7 and the arc-shaped scraper 10 to move back and forth, so that the alkaline resin flowing out of the slit coating die body 7 is in contact with the anion exchange membrane, and the arc-shaped scraper 10 is used to scrape off the excess alkaline resin.
