Description

Technical Field

[0001] This invention relates to the field of knitwear spraying technology, specifically to an antibacterial coating spraying device for yak wool knitwear. Background Technology

[0002] Yak wool knitwear is a high-end natural fiber product made from the downy hair of yaks from the Qinghai-Tibet Plateau through a fine textile process. The yak wool fiber structure has a bamboo-like medullary layer and dense scales, which have the advantages of strong warmth retention, good breathability, durability and resistance to damage, and natural hypoallergenic properties.

[0003] Currently, in the production process of yak wool knitwear, an antibacterial coating is required on the yak wool fabric. However, the presence of dust and loose fibers on the fabric surface can easily affect the antibacterial coating process, leading to uneven spraying. Furthermore, most spraying devices typically spray the antibacterial material onto the fabric through a nozzle, leaving the material on the surface. This prevents the fabric from fully contacting the antibacterial material, affecting the quality of the coating process. To address these issues, the inventor proposes an antibacterial coating spraying device for yak wool knitwear. Summary of the Invention

[0047] Two spraying boxes 301 are each slidably installed with drive bars 304 on both sides. The two ends of the drive bars 304 are slidably inserted into the extrusion box 201 and the cleaning box 401, respectively. The two ends of the drive bars 304 are connected to the recycling box 202 and the moving frame 402, respectively. Two moving frames 207 are fixedly connected to the drive bars 304. Two electric cylinders 305 are fixedly installed on the sides of the two spraying boxes 301 that are far apart from each other. The ends of the output shafts of the two electric cylinders 305 that are close to each other are fixedly connected to the drive bars 304.

[0048] By adopting the above technical solution, the electric cylinder 305 can drive the recycling box 202 and the moving frame 402 to move.

[0049] Working principle: First, the electric cylinder 305 is turned on to drive the drive bar 304 to move. The movement of the drive bar 304 drives the recycling box 202 and the moving frame 402 to move. The movement of the recycling box 202 drives the squeezing roller 203 to move, so that the outer surfaces of the two squeezing rollers 203 come into contact with the two sides of the fabric. The movement of the moving frame 402 drives the brush roller 403 and the rotating roller 410 to move, so that the bristles of the rotating roller 410 and the brush roller 403 come into contact with the two sides of the fabric. At this time, the rotating roller 410 limits the movement of the fabric, reducing the shaking of the fabric caused by cleaning. Next, turn on motor 307 to drive drive rod 306 to rotate. The rotation of drive rod 306 drives fourth bevel gear 309 to rotate. The rotation of fourth bevel gear 309 drives third bevel gear 308 to rotate. The rotation of third bevel gear 308 drives bidirectional screw 303 to rotate. The rotation of bidirectional screw 303 drives guide plate 302 to move. The movement of guide plate 302 drives guide rod 311 to move. The movement of guide rod 311 drives nozzle 310 to move, so that nozzle 310 can be adjusted according to the size of the fabric. Then, turn on motor 409 to drive the rotating rod 408 to rotate. The rotation of the rotating rod 408 drives the sleeve 411 to rotate. The rotation of the sleeve 411 drives the first bevel gear 412 to rotate. The rotation of the first bevel gear 412 drives the second bevel gear 413 to rotate. The rotation of the second bevel gear 413 drives the brush roller 403 to rotate. The brush roller 403 cleans both sides of the fabric. At the same time, turn on the vacuum cleaner 405 to collect the cleaned dust and loose hair. At the same time, the collision between the bristles of the brush roller 403 and the stop bar 404 cleans the dust and loose hair adhering to the bristles of the brush roller 403, preventing the dust and loose hair from re-adhering to the fabric. Finally, the antibacterial material is sprayed through nozzle 310, allowing it to adhere to the fabric. Then, motor 206 is turned on to drive transmission rod 205 to rotate. The rotation of transmission rod 205 drives sleeve 211 to rotate, which in turn drives second bevel gear 210 to rotate. The rotation of second bevel gear 210 drives first bevel gear 204 to rotate, which in turn drives extrusion roller 203 to rotate. Extrusion roller 203 presses the antibacterial coating into the fabric, improving its penetration. Simultaneously, scraper 208 contacts the fabric to scrape off excess antibacterial material after extrusion. Scraper 209 scrapes off antibacterial material adhering to the outer surface of extrusion roller 203, thus recovering the antibacterial material.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
