AI Technical Summary
Existing coating equipment suffers from paint loss due to wrinkles in the needle-punched felt when spraying on needle-punched felt.
A coating device is designed, including a support, a feed roller, a spreading plate, a guide roller, a spraying mechanism, and a take-up roller. The top of the spreading plate is raised in the middle and extends downward in an arc on both sides. When the needle-punched felt passes through the spreading plate under tension, the folds are pulled open. The spraying mechanism is set on both sides of the needle-punched felt. The height and angle of the spreading plate are adjusted by the adjusting frame and the lifting assembly to ensure optimal contact.
It effectively avoids the lack of coating in the wrinkled areas of needle-punched felt, improving the uniformity and integrity of the coating.
