Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a self-cleaning micro-tapered slit coating head. Background Technology

[0002] In modern industrial production, especially in fields such as electronic component manufacturing and precision printing, the requirements for the precision and efficiency of coating processes are becoming increasingly stringent. Traditional coating heads have many problems during use, such as poor coating uniformity, making it difficult to meet the production needs of high-precision products and easily leading to unstable product quality. At the same time, the angle adjustment of traditional coating heads is inconvenient, and they cannot be flexibly adjusted when facing diverse coating tasks, limiting the applicability of the equipment. In addition, after the coating operation is completed, cleaning traditional coating heads is difficult, and material residues in the slits can easily cause blockages, affecting subsequent use. Moreover, manual cleaning is costly and time-consuming. With the expansion of production scale and the pursuit of production efficiency, there is a need for a coating head that can achieve precise and uniform coating, flexible angle adjustment, and self-cleaning function. Utility Model Content

[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art by providing a self-cleaning micro-tapered slit coating head. The slit structure enables precise and uniform coating. Compared with traditional spraying methods, it can form a fine and uniform coating on the material surface, reducing material waste and greatly improving product consistency and reliability. It is suitable for high-precision fields such as electronic component manufacturing. Through the cooperation of components such as the positive and negative threaded rod, L-shaped part and rotating shaft, the die head angle can be flexibly and accurately adjusted to enhance the applicability of the equipment. The electronic three-way valve and the electronic one-way valve work together to achieve the self-cleaning function, effectively preventing slit blockage and extending the service life of the coating head.

[0004] This utility model also provides a self-cleaning micro-tapered slit coating head and a feeding box.

[0030] Reference Figure 1-4This utility model embodiment of a self-cleaning micro-tapered slit coating head includes a feeding box 23. A first die head 1 is arranged on the left side of the feeding box 23, and a second die head 2 is arranged on the right side of the feeding box 23. A main pipe 3 is fixedly connected to the center of the upper surface of the feeding box 23, and an electronic three-way valve 4 is fixedly connected to the upper end of the main pipe 3. A flow channel 13 is arranged inside the feeding box 23, and an angle adjustment device is arranged on the left side of the feeding box 23. The angle adjustment device includes:

[0031] The fourth L-shaped part 22 has a first groove 20 on the front surface of the first mold head 1, and the inner wall of the first groove 20 is slidably connected to the fourth L-shaped part 22.

[0032] The first L-shaped part 10 and the front surface of the second mold head 2 are provided with a second sliding groove 21, and the inner wall of the second sliding groove 21 is slidably connected to the first L-shaped part 10.

[0033] A water pipe 5 is installed at the front end of the electronic three-way valve 4, and a cleaning solvent pipe 6 is installed at the rear end of the electronic three-way valve 4. When the electronic three-way valve 4 switches to the water pipe 5 and the cleaning solvent pipe 6, the water flow and the cleaning solvent enter the flow channel 13 through the same path to rinse and clean the interior and the slit of the die head. A connecting pipe 7 is installed at the upper end of the electronic three-way valve 4, and an electronic check valve 8 is installed at the upper end of the connecting pipe 7. A dye pipe 9 is installed at the upper end of the electronic check valve 8. At this time, the electronic check valve 8 is closed to prevent the cleaning medium from flowing back and contaminating the dye pipe 9.

[0034] The lower end of the main pipe 3 extends into the interior of the feed box 23 and connects with the flow channel 13. The two sides of the bottom of the flow channel 13 are provided with outflow grooves 24 that penetrate the feed box 23. The right end of the fourth L-shaped part 22 is provided with a first nut 11, and the left end of the first L-shaped part 10 is provided with a second nut 12. The inner walls of the first nut 11 and the second nut 12 are threaded with positive and negative thread rods 14 for precise adjustment of the angle of the first die head 1 and the second die head 2.

Then, it flows into the internal flow channel 13 of the feed box 23 through the main pipe 3. It flows out from the bottom of the flow channel 13 through the outlet grooves 24 on both sides to the first die head 1 and the second die head 2 for uniform coating.

[0036] If the coating angle needs to be adjusted, rotate the positive and negative threaded rod 14. The first nut 11 and the second nut 12 drive the fourth L-shaped part 22 and the first L-shaped part 10 to slide in the first slide groove 20 and the second slide groove 21. At the same time, the second L-shaped part 15 and the third L-shaped part 16 are assisted to rotate by the cooperation of the first fixing ring 17, the second fixing ring 18 and the rotating shaft 19, so as to achieve precise adjustment of the angle of the first die head 1 and the second die head 2.

[0037] After the coating task is completed, the cleaning stage begins. The electronic three-way valve 4 switches to the water pipe 5 and the cleaning solvent pipe 6. The water and cleaning solvent enter the flow channel 13 through the same path to rinse and clean the interior and the slit of the die head. At the same time, the electronic one-way valve 8 closes to prevent the cleaning medium from flowing back and contaminating the dye pipe 9. This cycle completes the entire process of coating, adjustment and cleaning.
