Abstract
Description
Technical Field
[0001] This utility model relates to the field of stirring equipment technology, specifically a dye stirring device for a dyeing machine. Background Technology
[0002] Dyeing refers to the process by which dyes are transferred from a dye bath onto fibers, forming a uniform, strong, and vibrant color. Different fibers have different chemical compositions, and therefore require different dyes. Cotton fabrics are mainly dyed with reactive dyes. Polyester fabrics are mainly dyed with disperse dyes, and common dyeing methods include high-temperature dyeing, carrier dyeing, and hot-melt dyeing. Modified polyester fabrics with anionic groups can also be dyed with cationic dyes, resulting in rich and vibrant colors. Nylon fabrics are mainly dyed with acid dyes, but can also be dyed with acidic mordant dyes, disperse dyes, and some direct dyes at near-boiling points. Acrylic fabrics are mainly dyed with cationic or disperse dyes. Vinylon fabrics are mainly dyed with vat, sulfur, and direct dyes. Polypropylene fabrics are difficult to dye, but after modification treatment, some can be dyed with disperse or acid dyes. Acetate fiber fabrics are mainly dyed with disperse dyes, and sometimes with insoluble azo dyes.
[0003] Currently, dyeing is usually done using a dyeing machine. Before dyeing, the dye needs to be added into the dyeing machine. Since most dyes are plant extracts such as plant fruits and tree sap, and also contain natural chemical extracts such as coal tar, the dye needs to be mixed and stirred in the dye mixing tank before being added. Only after it is evenly mixed can it be added to the dyeing machine to dye the textile fabric.
[0004] Existing dye mixing devices typically include a mixing tank with a stirring paddle inside. The stirring paddle is connected to a motor, and the motor drives the stirring paddle to rotate, which can uniformly mix the dye inside the mixing tank. However, because dyes have a certain viscosity, after being added to the mixing tank for a period of time, they tend to adhere to the inner wall of the mixing tank and solidify to form dirt, which is difficult to clean and is time-consuming and labor-intensive to operate. Utility Model Content
[0005] The purpose of this invention is to provide a dye stirring device for a dyeing machine in order to solve the above-mentioned problems.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a dye stirring device for a dyeing machine, comprising a stirring tank, an stirring paddle disposed inside the stirring tank, a drive motor disposed at the bottom of the stirring tank, the stirring paddle being fixedly connected to the output end of the drive motor, the stirring paddle including a rotating rod, the rotating rod being provided with a plurality of stirring mechanisms, the stirring mechanism including a stirring frame fixedly connected to the rotating rod, and a scraper being rotatably connected to the end of the stirring frame away from the rotating rod via a connecting assembly, the connecting assembly being used to make the scraper inclined on the stirring frame and in contact with the inner sidewall of the stirring tank in a natural state.
[0007] As a further feature of this utility model, the connecting assembly includes a connecting piece fixedly connected to the stirring rack, two connecting sleeves are provided on the connecting piece, a rotating shaft is provided on the scraper, the two ends of the rotating shaft pass through the connecting sleeves and are rotatably connected between the connecting sleeves, and elastic elements are provided between the two ends of the rotating shaft passing through the connecting sleeves and the connecting sleeves.

[0010] As a further feature of this invention, the scraper is fixedly connected to the mounting plate by a number of screws.
[0011] As a further feature of this invention, a feeding mechanism is provided on the side wall of the mixing tank. The feeding mechanism includes a water pump, one end of which is connected to a suction pipe and the other end of which is connected to a feeding pipe. The end of the feeding pipe away from the water pump is connected to the inside of the mixing tank.
[0012] As a further feature of this invention, the bottom of the mixing tank is provided with several support feet, and rollers are rotatably connected to the support feet.
[0013] As a further feature of this invention, the scraper is made of stainless steel.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention uses a drive motor to rotate a rotating rod, which in turn rotates a stirring frame, enabling uniform stirring of the dye on the inner wall of the mixing tank. During this process, the scraper rotates simultaneously with the stirring frame, continuously scraping across the inner wall of the mixing tank and removing the dye adhering to it. Because the scraper is angled, it can move counterclockwise, aligning with the stirring direction of the stirring frame, thus preventing jamming and ensuring smooth rotation of the stirring paddle. This allows the scraper to easily remove the dye, preventing it from solidifying and forming dirt on the inner wall of the mixing tank, eliminating the need for tedious subsequent cleaning. The operation is convenient, simple, time-saving, and labor-saving. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3As shown, a dye stirring device for a dyeing machine includes a stirring tank 1. A discharge pipe is provided on the stirring tank 1 for discharging the uniformly stirred dye. An stirring paddle is installed inside the stirring tank 1, and a drive motor 2 is located at the bottom of the stirring tank 1. The stirring paddle is fixedly connected to the output end of the drive motor 2. The stirring paddle includes a rotating rod 3, on which several stirring mechanisms are provided. Each stirring mechanism includes a stirring frame 4 fixedly connected to the rotating rod 3. A scraper 5 is rotatably connected to the end of the stirring frame 4 away from the rotating rod 3 via a connecting assembly. The scraper 5 is made of stainless steel, which has high strength and hardness, is not easily corroded, and has good durability. The connecting assembly is used to allow the scraper 5 to be inclined on the stirring frame 4 and relative to the stirring tank 1 in its natural state. When the inner wall is in contact with the device, the rotating rod 3 can be driven by the drive motor 2 to rotate, thereby driving the stirring frame 4 to rotate as well. This allows for uniform stirring of the dye on the inner wall of the stirring tank 1. During this process, the scraper 5 will rotate simultaneously with the stirring frame 4, continuously scraping across the inner wall of the stirring tank 1 and removing the dye adhering to it. Since the scraper 5 is inclined, it can move counterclockwise, which is consistent with the stirring direction of the stirring frame 4, thus avoiding jamming and ensuring smooth rotation of the stirring paddle. This allows the scraper 5 to easily scrape off the dye, preventing it from solidifying on the inner wall of the stirring tank 1 and forming dirt. This eliminates the need for tedious subsequent cleaning operations, making the operation convenient, simple, time-saving, and labor-saving.
[0022] Please see Figure 2 , Figure 3 As shown, the connecting assembly includes a connecting piece 6 fixedly connected to the stirring frame 4. Two connecting sleeves 7 are provided on the connecting piece 6, and a rotating shaft 8 is provided on the scraper 5. Both ends of the rotating shaft 8 pass through the connecting sleeves 7 and are rotatably connected between them. Elastic elements are provided between both ends of the rotating shaft 8 passing through the connecting sleeves 7 and the connecting sleeves 7. Through the connection between the rotating shaft 8 and the connecting sleeves 7, the scraper 5 can deflect relative to the stirring frame 4. The elastic support of the elastic elements allows the scraper 5 to be tilted on the stirring frame 4. When the scraper 5 scrapes the inner wall of the mixing tank 1, it is subjected to friction, causing the scraper 5 to rotate slightly. The scraper 5 is supported by an elastic element, which allows it to quickly return to its original position. This ensures that the scraper 5 always maintains an elastic contact with the inner wall of the mixing tank 1. While ensuring the scraping effect, this avoids excessive scraping force that could cause wear on the inner wall of the mixing tank 1, and makes scraping easier and smoother. The elastic element includes a torsion spring 9, with one end of the torsion spring 9 connected to the rotating shaft 8 and the other end connected to the connecting sleeve 7. When the scraper 5 is deflected due to friction, the rotating shaft 8 will rotate accordingly, which will cause the torsion spring 9 to deform, thereby mitigating the impact. When the external force disappears, the torsion spring 9 will rebound and return to its original shape, thereby causing the scraper 5 to return to its original position.
[0023] Please see Figure 2 , Figure 3As shown, a mounting plate 10 is provided on the rotating shaft 8, and the scraper 5 is detachably mounted on the mounting plate 10. When the scraper 5 is worn and deformed due to long-term use, the scraper 5 can be removed from the mounting plate 10 and replaced in time, thereby ensuring the performance of the scraper 5. The scraper 5 is fixedly connected to the mounting plate 10 by several screws 11, which has good connection and is easy to disassemble and assemble.
[0024] Please see Figure 1 , Figure 2 As shown, a feeding mechanism is provided on the side wall of the mixing tank 1. The feeding mechanism includes a water pump 12, one end of which is connected to a suction pipe 13, and the other end is connected to a feeding pipe 14. The end of the feeding pipe 14 away from the water pump 12 is connected to the inside of the mixing tank 1. When the device is in use, the water pump 12 can be started to extract the dye through the suction pipe 13 and then input into the mixing tank 1 through the feeding pipe 14. The feeding operation is relatively convenient and simple, and the efficiency is relatively high. Several support feet 15 are provided at the bottom of the mixing tank 1, and rollers 16 are rotatably connected to the support feet 15. The mixing tank 1 can be moved by pushing the mixing tank 1, causing the rollers 16 to roll. The setting of the rollers 16 makes the operation of moving the mixing tank 1 easier and less labor-intensive.
