Abstract

This utility model relates to a dyeing device for processing denim fabric modified from kapok fiber, applied in the field of textile processing technology. The device involves inserting a mixing drum into a base, then securing it with clamps and bolts. The output of a servo motor is then connected to a docking block via a clamping block. The feed port is opened to allow the color paste to be placed into the mixing drum. The servo motor is then activated to drive the rotating shaft, which in turn drives the mixing paddle to stir and mix the color paste, preventing sedimentation. As the mixing paddle rotates, multiple rollers contact and roll against the inner wall of the mixing drum. Even if color paste sediment or clumps form, the rolling action of the rollers crushes the sediment, ensuring thorough mixing with the liquid. The uniformly mixed color paste exits through the discharge port and enters the dyeing chamber via a conveying pipe for dyeing the denim fabric. After the dyeing process is complete, the sealing cover can be rotated open to clean the inside of the mixing drum and the stirring mechanism.

Description

Technical Field

[0001] This utility model relates to a dyeing device for processing modified denim fabric, and more particularly to a dyeing device for processing kapok fiber modified denim fabric applied in the field of textile processing technology. Background Technology

[0002] Denim fabric is widely used in the clothing industry due to its unique style and durability. As people's requirements for the performance of clothing fabrics continue to increase, denim fabric modified with kapok fiber has gradually attracted attention. Kapok fiber has excellent properties such as lightness, warmth, and moisture absorption. Using it to modify denim fabric can improve the overall performance of the fabric.

[0003] Chinese patent CN208279867U discloses a dyeing guide device for denim fabric processing. In this utility model, a detachable brush is added below the main roller shaft. When the guide device needs to be cleaned after use, the two ends of the cleaning brush plate with brush bristles can be respectively inserted into the locking holes on both sides of the inner wall of the machine frame through locking blocks, so that the brush bristles are attached to the bottom of the main roller shaft. When the main roller shaft rotates, the brush bristles clean all the dye and debris on the outer surface of the main roller shaft, without affecting the next use. Alternatively, the cleaning brush plate can be disassembled for further cleaning of the brush bristles.

[0004] Chinese patent CN217948487U discloses a dyeing device for processing workwear fabric. This utility model uses a descending and moving first pressure roller to squeeze the parallel moving fabric into the dyeing liquid in the first chamber. After dyeing, the fabric is moved into the second chamber for drying. The dripping dyeing liquid is collected and transported to the inside of the barrel through a collection hopper, which achieves the effect of conveniently recycling the dripping dyeing liquid and preventing it from dripping onto the ground and causing pollution.

[0005] In the dyeing process of modified denim fabric with kapok fiber, a large amount of color paste needs to be prepared. Since the color paste needs to be used continuously for a certain period of time, the color paste often settles during the use of the color paste, resulting in uneven dyeing of the fabric. Utility Model Content

[0006] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that because color paste needs to be used continuously for a certain period of time, color paste sedimentation often occurs during the use of color paste, resulting in uneven dyeing of fabric.

[0007] To address the aforementioned problems, this utility model provides a dyeing device for processing denim fabric modified from kapok fiber. The device includes a dyeing box, a mixing tank with a sealed lid mounted on the top of the dyeing box, a rotating shaft rotatably connected to the end of the mixing tank away from the sealed lid, a controller fixedly connected to the top of the dyeing box, a servo motor fixedly connected to the controller, and the output end of the servo motor connected to the rotating shaft. Multiple staggered stirring mechanisms are fitted onto the surface of the rotating shaft. Each stirring mechanism includes a sleeve fitted onto the surface of the rotating shaft, connecting rods symmetrically fixedly connected to the surface of the sleeves, and multiple mixing paddles fixedly connected to the surface of the connecting rods. A clamping plate is fixedly connected to the end of the connecting rod of two stirring mechanisms in the same direction away from the sleeve. A roller shaft is rotatably connected between the two clamping plates via a connecting shaft. A discharge port is opened on the side wall of the mixing tank, and a feed port is opened on the top of the dyeing box. A conveying pipe is threadedly connected between the feed port and the discharge port.

[0008] In the dyeing device described above, multiple mixing paddles can be set up to mix the color paste evenly. At the same time, the roller shaft is driven to roll against the inner wall of the mixing drum, thereby crushing the precipitated color paste and preventing it from clumping and settling to the bottom, which would affect the uneven dyeing of denim fabric.

[0009] As a further supplement to this application, a docking block is connected to the end of the rotating shaft near the servo motor, and a locking block is fixedly connected to the output end of the servo motor, and the locking block engages with the locking slot opened on the docking block.

[0010] As a further supplement to this application, a plurality of protrusions are fixedly connected at equal intervals on the surface of the connecting shaft, and a filter screen is installed on the inner wall of the discharge port, with the protrusions in contact with the filter screen.

[0011] As a further supplement to this application, the dyeing box is symmetrically fixedly connected to a base at the top, and the mixing barrel is inserted into the base. The upper surface of the base is fitted with a clamp corresponding to the base, and the clamp is fixed to the base by bolts.

[0012] As a further supplement to this application, the rotating shaft surface is provided with multiple sets of screw holes corresponding to the stirring mechanism, and a ferrule is fitted onto the rotating shaft surface, with screws threaded onto the ferrule to match the screw holes.

[0013] As a further supplement to this application, a feeding port is provided at the top of the mixing tank, and a viewing window is installed on the top wall of the mixing tank.

[0014] In summary, the mixing tank is inserted into the base and then secured with clamps and bolts to install it. The servo motor output is then connected to the docking block via a clamping block. The feed port is then opened to place the color paste into the mixing tank. The controller then activates the servo motor to drive the rotating shaft, which in turn drives the mixing paddle to stir and mix the color paste, preventing sedimentation. As the mixing paddle rotates, multiple rollers contact the inner wall of the mixing tank, rolling to crush any sediment or clumps. This crushing action ensures the sediment and liquid are fully integrated. The uniformly mixed color paste flows from the outlet through a conveying pipe into the dyeing chamber for dyeing denim fabric. During the dyeing process, the uniformity of the color paste can be observed through a viewing window. After the dyeing process is complete, the sealing cover can be rotated open to clean the inside of the mixing tank and the stirring mechanism. Attached Figure Description

[0017] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] First implementation method: Figures 1-4 and Figure 6A dyeing apparatus for processing denim fabric modified with kapok fiber is shown, including a dyeing box 1, a mixing tank 4 with a sealing cover 12 installed at the top of the dyeing box 1, a rotating shaft 14 rotatably connected to the end of the mixing tank 4 away from the sealing cover 12, a controller 2 fixedly connected to the top of the dyeing box 1, a servo motor 3 fixedly connected to the controller 2, and the output end of the servo motor 3 connected to the rotating shaft 14, a plurality of staggered stirring mechanisms sleeved on the surface of the rotating shaft 14, a sleeve 15 sleeved on the surface of the rotating shaft 14, a connecting rod 16 symmetrically fixedly connected to the surface of the sleeve 15, a plurality of mixing paddles 17 fixedly connected to the surface of the connecting rod 16, a clamping plate 18 fixedly connected to the end of the connecting rod 16 on two stirring mechanisms in the same direction away from the sleeve 15, a roller shaft 13 rotatably connected between the two clamping plates 18 through a connecting shaft 19, a discharge port 9 opened on the side wall of the mixing tank 4, a feed port 8 opened at the top of the dyeing box 1, and a conveying pipe 10 threadedly connected between the feed port 8 and the discharge port 9; A docking block 11 is connected to one end of the rotating shaft 14 near the servo motor 3. A locking block 22 is fixedly connected to the output end of the servo motor 3, and the locking block 22 engages with the slot opened on the docking block 11. A feeding port is opened on the top of the mixing tank 4, and a viewing window is installed on the top wall of the mixing tank 4.

[0019] Working principle: The mixing tank 4 is inserted into the base 6 and then connected to it by clamps 5 and bolts 7 to install the mixing tank 4. Then, the output end of the servo motor 3 is connected to the docking block 11 by the clamp 22. At this time, the feeding port is opened and the color paste is placed into the mixing tank 4. Then, the controller 2 turns on the servo motor 3 to drive the rotating shaft 14 to drive the mixing paddle 17 to stir and mix, so as to avoid the color paste from settling. While the mixing paddle 17 is rotating, it drives multiple rollers 13 to contact the inner wall of the mixing tank 4 and roll. Even if there is color paste settling or clumping, it can be crushed by the rolling of the rollers 13. The crushing action of the rollers 13 makes the sediment fully blended with the liquid. The uniformly mixed color paste enters the dyeing box 1 from the discharge port 9 through the conveying pipe 10 for dyeing denim fabric. During the dyeing process, the uniformity of the color paste can be observed through the viewing window. After the dyeing process is completed, the sealing cover 12 can be rotated open to clean the inside of the mixing tank 4 and the stirring mechanism. This invention uses multiple mixing paddles 17 to uniformly mix the color paste, while simultaneously driving the roller 13 to roll against the inner wall of the mixing drum 4, thereby crushing the precipitated color paste and preventing it from clumping and settling to the bottom, which would affect the uneven dyeing of denim fabric.

[0020] Second implementation method: Figure 5 and Figure 7The connecting shaft 19 has multiple protrusions 21 fixedly connected at equal intervals on its surface. A filter screen 23 is installed on the inner wall of the discharge port 9, and the protrusions 21 are in contact with the filter screen 23. A base 6 is symmetrically fixedly connected to the top of the dyeing box 1, and the mixing tank 4 is clamped in the base 6. A clamp 5 corresponding to the base 6 is clamped on the upper surface of the base 6, and the clamp 5 is fixed to the base 6 by bolts 7. The rotating shaft 14 has multiple sets of screw holes corresponding to the stirring mechanism on its surface, and a sleeve 15 is fitted on the surface of the rotating shaft 14, and a screw 20 matching the screw hole is threaded on the sleeve 15.

[0021] Working principle: During the rolling of the roller 13, the protrusions 21 on the surface can better crush the clumps of pigment paste. And whenever the roller 13 and the mixing tank 4 roll past the filter screen 23 in the discharge port 9, the protrusions 21 can scrape the surface of the filter screen 23 to prevent pigment paste clumps from blocking the filter screen 23 and affecting the delivery of pigment paste. When the dyeing is finished, when the sealing cover 12 is opened to clean the mixing tank 4, the screw 20 can be turned to slide the stirring mechanism on the rotating shaft 14 off the top, so that the stirring mechanism can be cleaned more thoroughly. In this invention, a protrusion 21 is provided on the surface of the roller 13, which can clean the surface of the filter screen 23 during operation and prevent it from clogging and affecting the delivery of color paste. The detachable design of the stirring mechanism makes it easy to clean.

[0022] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
