Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a yarn surface treatment mechanism for a textile yarn desizing machine. Background Technology

[0002] Yarn is a type of textile product made from various textile fibers processed into a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery. Yarn is divided into short fiber yarn and continuous filament yarn. Yarn spinning is a process of processing natural or chemical fibers to form products of different fineness. The main products include three categories: short fiber yarn, continuous filament yarn, and blended yarn. According to the raw materials, it can be divided into pure spun yarn (single fiber) and blended yarn (multiple fiber mixture). According to the spinning method, it can be divided into ring-spun yarn, air-jet yarn, etc. Its uses cover weaving yarn, knitting yarn, and special yarn.

[0003] Before weaving, warp yarns need to be sized to improve their strength, abrasion resistance, and smoothness. However, residual sizing can contaminate the dyeing and finishing solution, hindering the effective contact between dyes / chemicals and fibers, leading to problems such as uneven dyeing and color variations. At the same time, the sizing film covering the fiber surface reduces the hydrophilicity and permeability of the fabric, which is not conducive to the penetration of chemical reagents in processes such as scouring and bleaching. Therefore, fabrics are generally desized first. There are various desizing methods, mainly including hot water desizing, alkaline desizing, enzyme desizing, and oxidizing agent desizing. All desizing methods require the use of a desizing machine.

[0004] However, when desizing elastic fabrics, a large amount of sizing film is easily left between the fibers, resulting in low desizing efficiency. In order to facilitate the desizing of the yarn surface of elastic fabrics, a yarn surface treatment mechanism for textile yarn desizing machines is provided. Summary of the Invention

[0020] Please see Figures 1 to 10 In this embodiment of the invention, a yarn surface treatment mechanism for a textile yarn desizing machine includes a desizing tank 1, a desizing groove 2 at the top of the desizing tank 1, a power roller 3 and a connecting roller 4 symmetrically rotatably connected to the inner wall of the desizing groove 2, rotatable guide rollers 5 symmetrically installed at the top of the desizing tank 1, a mounting frame 8 fixedly connected to one side of the outer wall of the desizing tank 1, a motor 9 installed on the outer wall of the mounting frame 8, a first spur gear 10 connected to the output end of the motor 9, a second spur gear 11 rotatably connected to the outer wall of the desizing tank 1 located on the outer wall of the first spur gear 10, one end of the power roller 3 fixedly connected to the second spur gear 11, and the fabric being stretched by a stretching unit 6.

[0021] In this embodiment: the desizing tank 2 contains desizing liquid. The fabric enters the desizing tank 2 from one guide roller 5, passes through two power rollers 3, and then moves out of the desizing tank 2 and moves out from another guide roller 5. The power roller 3 and the connecting roller 4 clamp the fabric. The motor 9 is started, and the motor 9 drives the first spur gear 10 to rotate. The rotation of the first spur gear 10 drives the two second spur gears 11 to rotate synchronously. The rotation of the second spur gears 11 drives the power roller 3 to rotate, and the rotation of the power roller 3 drives the fabric to move.

[0022] Please refer to this carefully. Figures 2 to 7The stretching unit 6 includes a mounting frame 601, which is fixedly connected to the bottom of the inner wall of the deslurry tank 2. A movable groove 602 is provided on the inner wall of the mounting frame 601. A movable plate 603 is symmetrically slidably connected to the inner wall of the movable groove 602. A first spring 604 connects the movable plate 603 and the mounting frame 601. A movable rod 605 is fixedly connected to the outer wall of the movable plate 603. A rotating disk 606 is rotatably connected to one side of the inner wall of the deslurry tank 2. The rotating disk 606 rotates via a rotating unit 7. The stretching unit 6 also includes a displacement groove 607, which is symmetrically provided on the outer wall of the rotating disk 606. A displacement block 608 is slidably connected to the inner wall of the displacement groove 607. A push rod 609 is fixedly connected to the outer wall of the displacement block 608. The internal rotation of the rotating disk 606... A threaded rod 610 is connected through the displacement block 608. A first bevel gear 611 is fixedly connected to the outer wall of the threaded rod 610. A second bevel gear 612 is symmetrically rotatably connected to the outer wall of the first bevel gear 611 inside the rotating disk 606. A rotating column 613 is fixedly connected to one end of the second bevel gear 612. A first square groove 614 is opened at one end of the rotating column 613. A horizontal plate 615 is fixedly connected to the top of the deslurry tank 1 above the rotating disk 606. A rotating block 616 is rotatably connected inside the horizontal plate 615. A first square rod 617 is slidably connected to the inner wall of the rotating block 616. A circular plate 618 is fixedly connected to the top of the first square rod 617. A second spring 619 is connected between the circular plate 618 and the rotating block 616.

[0023] In this embodiment: the fabric passes through the space between the movable rods 605 during movement (e.g., Figure 2 As shown, through the cooperation of the parts inside the rotating unit 7, the rotating disk 606 rotates, and the rotation of the rotating disk 606 drives the push rod 609 to perform circumferential displacement. The displacement of the push rod 609 contacts the movable plate 603, pushing the movable plate 603 to slide in the movable groove 602, causing compression on the first spring 604. When the push rod 609 moves away from the movable plate 603, the movable plate 603 is in contact with the outer wall of the push rod 609 by the elastic force of the first spring 604. Thus, during the rotation of the rotating disk 606, the two movable plates 603 are driven to move back and forth in opposite directions. The displacement of the movable plate 603 drives the movable rod 605 to move. The displacement of the movable rod 605 contacts the fabric, stretching the fabric and increasing the fiber gap of the fabric, so that the desizing liquid can better contact the fibers and improve the desizing effect. When adjusting the position of the push rod 609, the two movable plates 603 move closer together under the elastic force of the first spring 604, causing the two push rods 609 to be in a horizontal state. This makes the first square groove 614 on one of the rotating columns 613 face upward. At this time, the circular plate 618 is pushed downward, compressing the second spring 619. The displacement of the circular plate 618 causes the first square rod 617 to move, inserting into the first square groove 614. The circular plate 618 can then be rotated, causing the first square rod 617 to rotate. The rotation of the first square rod 617 causes the rotating column 613 to rotate, which in turn causes the second bevel gear 612 to rotate. The rotation of the second bevel gear 612 causes the first bevel gear 611 to rotate, and the rotation of the first bevel gear 611 causes the threaded rod 61... The threaded rod 610 rotates, causing the displacement block 608 to slide within the displacement groove 607. The two displacement blocks 608 move in opposite directions, causing the push rod 609 to move, thereby adjusting the position of the push rod 609 on the rotating disk 606. This adjusts the pushing distance of the push rod 609 on the movable plate 603 and the movable rod 605 during the rotation of the rotating disk 606, thus adjusting the stretching depth on the opposite side. After completion, the circular plate 618 is released, and the circular plate 618 is reset by the elastic force of the second spring 619. The displacement of the circular plate 618 causes the first square rod 617 to move out of the first square groove 614, which facilitates automatic stretching of the fabric when the fabric moves, increases the fiber gap of the fabric, and allows the desizing liquid to better contact the fibers, improving the desizing effect. At the same time, the degree of stretching of the fabric can be adjusted according to the elasticity of different fabrics.

[0024] Please refer to this carefully. Figures 8 to 10 The rotating unit 7 includes a first synchronous wheel 701 and a second synchronous wheel 703.

The outer wall of the deslurry tank 1 is rotatably connected to a third spur gear 704 on one side of the second synchronous wheel 703.

The rotation of the second synchronous pulley 703 drives the first synchronous pulley 701 to rotate via the synchronous belt 702. The rotation of the first synchronous pulley 701 drives the rotating disk 606 to rotate. The rotation of the rotating disk 606 automatically stretches the fabric through the cooperation of the parts inside the stretching unit 6. When adjusting the position of the push rod 609 on the rotating disk 606, the second square rod 706 is pushed to move out of the second square groove 707, so that the third spur gear 704 is separated from the second synchronous pulley 703, thereby facilitating the adjustment operation of the push rod 609.
