Description

Technical Field

[0002] Yarn dyeing is a process whereby yarn or thread is soaked in dye so that it absorbs the dye color. This process is usually done in a factory or a specialized dyeing studio. Yarn dyeing is commonly used to add color to yarn, thread or fabric.

[0003] Yarn dyeing usually passes through a dyeing tank, and when the yarn is finished dyeing and discharged from the dyeing tank, a scraper is installed on the side of the dyeing tank. When the dyed yarn passes through the scraper, the scraper and the yarn have an extrusion friction force, so that the scraper removes excess water and pigment solution on the yarn. However, yarns of different materials and different thicknesses have different internal water absorption amounts, and using only one scraper is not convenient for changing the scraper to apply a corresponding extrusion scraping force to the yarn according to the material and model of the yarn.

The mounting frame 1 is provided with a locking component 6, and the locking component 6 is arranged on the fixed shell 4 to lock the adjustment component 5. The interior of the mounting frame 1 is symmetrically rotated with guide rollers 7. The two guide rollers 7 can guide the yarn entering between the first scraper 2 and the second scraper 3, so that the yarn enters and exits from between the first scraper 2 and the second scraper 3 at a specified angle.

[0027] The first and second scrapers 2 and 3 are slidably engaged with each other through the slider 51, that is, both sides of the first scraper 2 and both sides of the second scraper 3 are fixedly connected to the slider 51, and the connecting gear 53 is rotatably arranged inside the fixed shell 4. The connecting gear 53 rotates to drive the slider 51 to move vertically. The slider 51 is fixedly connected with a connecting tooth plate 54 on one side of the connecting gear 53, and the connecting tooth plate 54 is meshed with the connecting gear 53. A fixed shaft 52 is fixedly connected between the fixed shell 4 and the mounting frame 1. The connecting gear 53 is rotatably sleeved on the outer wall of the fixed shaft 52. Sliding holes are symmetrically provided on the sides of the mounting frame 1. The outer wall of the slider 51 is slidably sleeved with the inner cavity of the sliding hole.

The top of the positioning latch plate 61 is symmetrically fixedly connected with a fixing rod 63. The outer wall of the fixing rod 63 is slidably sleeved with the limit spring 62. The top of the fixing rod 63 passes through the fixed shell 4 and is fixedly connected with a connecting plate 64. The top of the connecting plate 64 is fixedly connected with a handle. The fixing rod 63 can ensure the stability of the vertical movement of the positioning latch plate 61 and the limit spring 62. The handle can be used to drive the positioning latch plate 61 to separate from the connecting gear 53, thereby adjusting the height difference between the first scraper 2 and the second scraper 3.
