Description

Technical Field

[0001] This utility model relates to the field of dyeing equipment technology, and in particular to a rotary dyeing device and dyeing equipment. Background Technology

[0002] Traditional dyeing equipment often requires a large amount of water to ensure thorough immersion and uniform coloring, which not only increases production costs but also burdens the environment. To address this challenge, the industry has gradually adopted low-water-level unidirectional dyeing as a water-saving measure. This method reduces the total volume of the dye liquor, allowing only a portion of the textile (usually the lower half) to be directly immersed in the dye liquor, while the upper half is exposed to air. While this design reduces water consumption to some extent, in low-water-level unidirectional dyeing systems, the textile is typically stationary, with the dye liquor flowing in from one end and gradually penetrating into the fabric. The portion not directly immersed relies on the penetration of the dye liquor and capillary action for coloring. This static dyeing method limits the full contact between the dye liquor and the textile, resulting in uneven penetration rates and easily causing a "watermark" phenomenon with varying color depths, affecting the overall aesthetics and quality consistency of the finished product. Utility Model Content

The rotating drive can drive the rotating drum to rotate through the connecting mechanism, so that the fabric wrapped around the rotating drum periodically comes into contact with the dye solution.

[0006] As an improvement to the above solution, the clamping mechanism includes a clamping shaft and a pressure cover. One end of the clamping shaft is connected to the movable end of the clamping drive, and the other end of the clamping shaft is movably connected to the pressure cover. The clamping drive can drive the clamping shaft to move in a direction close to or away from the pressure cover.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] See also Figure 1This utility model discloses a rotary dyeing device, including a cylinder 1, a rotating drum 2 disposed within the cylinder 1, a pressing assembly 3 disposed at one end of the cylinder 1, and a driving assembly 4 disposed at the other end of the cylinder 1. The cylinder 1 contains dye liquor, and the rotating drum 2 is brought into the cylinder 1 by a trolley. Fabric is wound around the outer wall of the rotating drum 2. After the rotating drum 2 enters the cylinder 1, part of the fabric is immersed in the dye liquor. In order to make the fabric dyed evenly, the driving assembly 4 is connected to the rotating drum 2 through a transmission. The driving assembly 4 can drive the rotating drum 2 to rotate. During the rotation, each part of the fabric can periodically come into contact with the dye liquor, so that the fabric can come into even contact with the dye liquor and improve the uniformity of dyeing. The pressing assembly 3 can pass through the cylinder 1 and be movably connected to the rotating drum 2, thereby forming a pressing effect on both ends of the rotating drum 2 with the connecting mechanism 42 to fix and support the rotating drum 2.

[0024] The pressing assembly 3 includes a pressing drive 31 and a pressing mechanism 32. The pressing mechanism 32 is in movable contact with the rotating drum 2. The pressing drive 31 can be a component with linear motion characteristics, such as a cylinder. The pressing drive 31 can drive the pressing mechanism 32 away from or towards the rotating drum 2, thereby controlling the degree of pressing of the pressing mechanism 32 on the rotating drum 2. On the other hand, the driving assembly 4 includes a rotating drive 41 and a connecting mechanism 42. The rotating drive 41 is preferably a component with rotational motion characteristics, such as a rotary motor. The connecting mechanism 42 is in contact with the rotating drum 2. The rotating drum 2 is partially immersed in the dye solution in the cylinder 1. The rotating drive 41 can drive the rotating drum 2 to rotate through the connecting mechanism 42, so that the fabric wrapped around the rotating drum 2 periodically comes into contact with the dye solution, achieving a uniform dyeing effect.

[0025] The beneficial effects of this utility model embodiment are as follows:

[0026] This utility model embodiment of the rotary dyeing device includes a cylinder 1, a rotating drum 2, a pressing assembly 3, and a driving assembly 4. The driving assembly 4 and the pressing assembly 3 are respectively located at both ends of the rotating drum 2. Fabric is wound around the rotating drum 2, which is located inside the cylinder 1. The cylinder 1 contains dye solution to soak the rotating drum 2. The pressing assembly 3 includes a pressing drive 31 and a pressing mechanism 32. The pressing drive 31 can drive the pressing mechanism 32 to press the rotating drum 2, preventing the rotating drum 2 from loosening. The driving assembly 4... 4 includes a rotating drive component 41 and a connecting mechanism 42. The connecting mechanism 42 abuts against the other end of the rotating drum 2, enabling the rotating drum 2 to rotate stably. The rotating drive component 41 can drive the rotating drum 2 to rotate. When the rotating drum 2 rotates, it can periodically drive the fabric wrapped around the rotating drum 2 to come into contact with the dye liquor, forming a dynamic dyeing effect. This makes the dye liquor on the fabric evenly distributed and diffused. Moreover, it does not require too much dye liquor to achieve uniform dyeing. Therefore, it can not only save water and reduce emissions, but also improve the dyeing uniformity and improve the quality of the finished product.

[0027] Specifically, see Figure 2 and Figure 3 The clamping mechanism 32 includes a clamping shaft 321 and a pressure cap 322. One end of the clamping shaft 321 is connected to the movable end of the clamping drive member 31, which can drive the clamping shaft 321 to extend or retract. The other end of the clamping shaft 321 is movably connected to the pressure cap 322, thus allowing the clamping drive member 31 to move the clamping shaft 321 towards or away from the pressure cap 322. The pressure cap 322 includes an outer clamping part 3221, which can press against one end of the rotating drum 2, thereby clamping the rotating drum 2. The clamping drive member 31's ability to drive the clamping shaft 321 to extend or retract controls the clamping force on the rotating drum 2.

[0028] See also Figure 3To enable the rotating drum 2 to rotate relative to the pressing shaft 321, the pressure cover 322 further includes an inner connecting cavity 3222. One end of the pressing shaft 321 can be inserted into the inner connecting cavity 3222, and the pressing shaft 321 and the inner connecting cavity 3222 form a movable connection. To reduce wear on the inner connecting cavity 3222 and ensure the coaxiality of the rotating drum 2, the inner connecting cavity 3222 is provided with a wear-resistant block 323 and a wear-resistant ring 324. The wear-resistant block 323 can abut against the end face of the pressing shaft 321, so that the pressing shaft 321 is less likely to cause axial damage to the inner connecting cavity 3222 when it extends or retracts. The inner wall of the wear-resistant ring 324 can abut against the side wall of the pressing shaft 321, so that when the rotating drum 2 rotates relative to the pressing shaft 321, the wear-resistant ring 324 can cause radial damage to the inner connecting cavity 3222.

[0029] Furthermore, if the wear-resistant block 323 wears down, the connection between the rotating drum 2 and the clamping shaft 321 may loosen, affecting the rotation efficiency and the lifespan of the inner connecting cavity 3222. To prevent this, the clamping mechanism 32 further includes an adjusting bolt 325 and an adjusting plate 326. The adjusting plate 326 is connected to the wear-resistant block 323, and one end of the adjusting bolt 325 passes through the inner connecting cavity 3222 and connects to the adjusting plate 326. The adjusting bolt 325 can adjust the position of the wear-resistant block 323 within the inner connecting cavity 3222. When the wear-resistant block 323 wears down, the connection tightness between the wear-resistant block 323 and the clamping shaft 321 decreases. At this time, the adjusting bolt 325 can be used to rotate the adjusting plate 326 within the inner connecting cavity 3222, thereby causing the wear-resistant block 323 to re-abut against the clamping shaft 321 and restoring its connection tightness.

[0030] See also Figure 4 The connecting mechanism 42 includes a transmission ring 421 and a transmission shaft 422. The rotary drive 41 is connected to the transmission shaft 422. The transmission shaft 422 is coaxially connected to the transmission ring 421. The transmission ring 421 has a limiting protrusion 4211 on its side. The limiting protrusion 4211 can be inserted into the end of the rotating drum 2 to form a fastening connection. The rotary drive 41 can drive the transmission ring 421 to rotate through the transmission shaft 422. The transmission ring 421 can drive the rotating drum 2 to rotate.

[0031] See also Figure 5To improve the system's sealing performance and prevent dye from entering the drive assembly 4, the drive assembly 4 further includes a sealing mechanism 43. The sealing mechanism 43 includes a first sealing ring 431, which is disposed between the end of the transmission ring 421 and the rotating drum 2, thereby preventing liquid from entering the rotating drum 2. The first sealing ring 431 can seal the drive ring axially.

[0032] To improve the coaxiality of the drive shaft 422, the connecting mechanism 42 further includes a first bearing 423 and a second bearing 424. The first bearing 423 is sleeved on one end of the drive shaft 422, and the second bearing 424 is sleeved on the other end of the drive shaft 422. The drive shaft 422 rotates between the first bearing 423 and the second bearing 424.

[0033] The connecting mechanism 42 further includes a first retaining ring 425 and a second retaining ring 426. The first retaining ring 425 is sleeved on one end of the transmission shaft 422 and abuts against the side of the first bearing 423. The second retaining ring 426 is sleeved on one end of the transmission shaft 422 and abuts against the side of the second bearing 424. The first retaining ring 425 and the second retaining ring 426 can respectively prevent the first bearing 423 and the second bearing 424 from unexpected axial movement during operation, ensuring stable operation of the bearings, and also providing a certain degree of waterproof and dustproof protection.

[0034] To fix the rotary drive component 41, the connecting mechanism 42 further includes a fixed cylinder 427. The rotary drive component 41 is fixed to the cylinder 1 via the fixed cylinder 427. The transmission ring 421 is rotatable relative to the fixed cylinder 427. A second sealing ring 432 is provided between the transmission ring 421 and the fixed cylinder 427. The second sealing ring 432 can seal the radial direction of the drive ring, further preventing liquid from entering the fixed cylinder 427.

[0035] See also Figure 1 This utility model also discloses a dyeing device, including the rotary dyeing apparatus described above. The rotary dyeing apparatus uses a pressing component 3 to press the rotating drum 2 containing the wound fabric, and a driving component 4 to rotate the rotating drum 2. During rotation, the fabric on the rotating drum 2 periodically comes into contact with the dye liquor, creating a dynamic dyeing effect, thereby ensuring uniform distribution and diffusion of the dye liquor on the fabric. Furthermore, it achieves uniform dyeing without requiring excessive amounts of dye liquor, thus not only saving water and reducing emissions, but also improving dyeing uniformity and finished product quality.

[0036] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
