Description

Technical Field

[0001] The invention relates to the technical field of yarn-dyed fabric production, and in particular to a drum drying device and a drying method for yarn-dyed fabric production. Background Art

[0002] Yarn-dyed fabric is a fabric woven with dyed yarn. Dyeing yarn is generally divided into two ways: spun yarn and dyed yarn. Usually, the yarn-dyed fabric refers to the fabric woven by shuttle looms, but knitting machines can also make yarn-dyed knitted fabrics. Compared with printed and dyed fabrics, it has a unique style, but the price is relatively expensive.

[0003] During the production process of yarn-dyed fabrics, a drum dryer is generally used to dry them. The rotation of the drum can make the fabric stick to the inner wall of the drum, expanding the heating area, but it cannot sort the fabric. The fabric attached to the inner wall of the drum will still accumulate, causing wrinkles on the fabric. After drying, ironing is required to eliminate wrinkles, and even uneven heating will occur, affecting the pattern and color. Summary of the invention

[0004] The invention discloses a drum drying device and a drying method for color-dyed fabric production, aiming to solve the technical problem that the rotation of the drum can make the fabric adhere to the inner wall of the drum to expand the heating area, but the fabric cannot be arranged, and the fabric adhered to the inner wall of the drum will still be piled up, causing wrinkles on the fabric, and ironing is required to eliminate the wrinkles after drying, and even uneven heating will be caused, which will affect the pattern and color.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A drum drying device for producing yarn-dyed fabrics comprises a drying drum, a sealing door is arranged on one side of the drying drum, a motor 1 is installed on the opposite side of the drying drum, a drum is arranged inside the drying drum, and a transition mechanism is arranged inside the drum, one side of the drum is connected to a limiting mechanism, one side of the transition mechanism is simultaneously movably connected to the limiting mechanism, a plurality of vents are equidistantly arranged on the drum, an output end of the motor 1 passes through the drying drum and is connected to the limiting mechanism, a connecting ring is fixedly connected to the outer periphery of the limiting mechanism and the drum respectively, and the connecting ring is movably clamped in the drying drum;

[0007] A first clamping groove is provided on the inner wall of one side of the drum, and a clamping strip is movably clamped in the first clamping groove, and a long strip clip is fixedly connected to one side of the clamping strip;

[0008] The transition mechanism includes a transition cylinder, and an opening is provided on one side of the transition cylinder. One side of the transition cylinder is fixedly connected to the drying cylinder through a support frame. Two empty grooves are symmetrically provided in the transition cylinder. An arc-shaped support plate 1 is connected to each of the empty grooves through a plurality of springs, and the outer wall of the arc-shaped support plate 1 is movably fitted to the inner wall of the empty groove. Rollers are movably connected to the opposite sides of the two arc-shaped support plates 1.

[0009] By providing a transition mechanism, the yarn-dyed fabric is stuffed into the transition cylinder, and the ends of the yarn-dyed fabric are clamped in the long strip clamp. As a result, when the motor drives the drum to rotate, the yarn-dyed fabric can be pulled out from the ends of the fabric. Under the action of centrifugal force, the yarn-dyed fabric can be driven to stick together and be stacked in multiple layers in the drum. During the process, the two rollers can arrange the fabric in the movement to prevent it from shifting. Under this structure, it can ensure that the fabric is heated evenly during the entire drying process, improve the drying efficiency, and also ensure that the color and pattern of the yarn-dyed fabric are not affected, and the ironing of the fabric can be completed while drying.

[0010] In a preferred solution, the two arc-shaped support plates are respectively fixedly connected to an articulated frame on one side thereof, and each articulated frame is respectively articulated to a support shaft 1, and the roller is sleeved on the support shaft 1;

[0011] A plurality of annular grooves are equidistantly arranged on each of the rollers, two grooves are symmetrically arranged on the outer wall of the transition cylinder, and a through groove 1 is arranged in each of the grooves, and an arc-shaped support plate 2 is movably connected in each of the grooves;

[0012] A connecting frame is fixedly connected to one side of each of the arc-shaped support plates 2, and the connecting frame passes through the through slot 1 and is connected to the arc-shaped support plate 1, and a second clamping slot is provided on the outer wall of each of the arc-shaped support plates 2;

[0013] Each of the two clamping slots is clamped with an arc-shaped support plate three, and the outer wall of each arc-shaped support plate three is fixedly connected with a waste collecting slot. A plurality of needles and a plurality of scrapers are arranged in the waste collecting slot, and each scraper is correspondingly fitted in a plurality of annular grooves.

[0014] By providing a transition mechanism, in which a scraper can clean the fibers adhered to the roller along the inner wall of the annular groove and is integrated on multiple scrapers, as the fibers continue to accumulate until they fall into the waste collecting trough, the provided needles provide limiting positions so that the fibers can be stably adhered to the waste collecting trough. Under this structure, the frequency of cleaning the scraper can be reduced while ensuring the cleaning effect of the roller.

[0015] In a preferred solution, the limiting mechanism includes a side support shell, and the side support shell is fixedly connected to one side of the drum, the motor 1 is connected to the side support shell, and one side of the side support shell is equidistantly penetrated with a plurality of linear through grooves;

[0021] S3: The colored fabric is pulled out from the opening of the transition drum synchronously, and the colored fabric is driven to adhere to the inner wall of the drum and stacked in multiple layers under the action of centrifugal force;

[0022] S4: Hot air enters the drum to dry the inner and outer layers of the yarn-dyed fabric simultaneously;

[0023] S5: Motor 2 drives the multiple pressure rods to extend outward;

[0024] S6: The drum stops rotating and the sealing door is opened to unload the material.

[0025] By setting a limiting mechanism, in the limiting mechanism, the support plate four is driven to rotate by the motor two, which can drive multiple pressure rods to shrink and expand synchronously. When the color-dyed fabric has not completely entered the drum from the transition tube, the multiple pressure rods are retracted to the outside of the transition tube to ensure that the waste collecting tank is not blocked. When the color-dyed fabric is completely located in the drum, the multiple pressure rods can be driven to expand outwards and get closer to the inner circle of the color-dyed fabric.

The outer wall of the arc-shaped support plate 504 is movably fitted to the inner wall of the empty slot 502. The opposite sides of the two arc-shaped support plates 504 are movably connected to rollers 507. When the yarn-dyed fabric is placed in the drum 7 for drying, the yarn-dyed fabric is stuffed into the transition cylinder 501, and the yarn-dyed fabric head is pulled out from the opening of the transition cylinder 501 and clamped in the long strip clamp 4. Thus, the motor 3 During the process of driving the drum 7 to rotate, as the long strip clamp 4 continues to rotate, the colored fabric can be pulled out from the cloth head, and under the action of centrifugal force, the colored fabric can be driven to stick together and be stacked in multiple layers in the drum 7. During the process, the two rollers 507 can arrange the fabric in the movement to prevent it from shifting, and under the action of the spring 503, the distance between the two rollers 507 can be changed, which is suitable for colored fabrics of different thicknesses. Under this structure, the fabric can be heated evenly during the entire drying process, and the drying efficiency is improved while also ensuring that the color and pattern of the colored fabric are not affected. In addition, based on the fact that the long strip clamp 4 is connected to the card slot 11 through the card strip 10, it can be pulled out when placing the fabric, reducing the difficulty of operation.

In the transition mechanism 5, the waste collecting groove 514 is continuously located on the outer side of the roller 507. As the roller 507 continues to contact with the yarn-dyed fabric, the excess fibers on the yarn-dyed fabric will adhere to the surface of the roller 507. At this time, through the rotation of the roller 507, the scraper 516 can adhere to the inner wall of the annular groove 508 to scrape the fibers adhered to the roller 507. The fibers are cleaned and integrated on a plurality of scrapers 516. As the fibers continue to accumulate, they fall into the waste collecting trough 514 and are limited by the provided needles 515, so that the fibers can be stably adhered to the waste collecting trough 514. Under this structure, the cleaning frequency of the scraper 516 can be reduced, while ensuring the cleaning effect of the roller 507. In addition, the waste collecting trough 514 is connected by the arc-shaped support plate three 513 clamped in the clamping slot two 512, and the provision of the connecting frame 517 can ensure that the waste collecting trough 514 can move along with the movement of the roller 507, thereby realizing the disassembly and cleaning of the waste collecting trough 514, reducing the difficulty of cleaning the waste collecting trough 514 and ensuring its thoroughness.
