Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing technology, specifically to a dyeing vat for dyeing recycled polyester. Background Technology

[0002] Recycled polyester is a polyethylene terephthalate fiber made by recycling waste polyester materials (such as PET bottle flakes, waste textiles, etc.). A dyeing vat for recycled polyester is a device specifically used to dye recycled polyester fibers. The vat body is the main component of the dyeing vat and is used to hold dyes and recycled polyester fibers to be dyed.

[0003] Existing technology CN215947609U discloses a dyeing device for recycled polyester fabric, including a machine body, a dyeing mechanism, and a control panel. A set of active winding rollers is located on the side of the top feed box of the machine body. A discharge port is located on the upper surface of the machine body away from the drive motor. A heating box is located on the lower surface of one front end of the machine body. The inner cavity of the machine body is divided into a dyeing chamber and a drying chamber. The dyeing mechanism includes a re-dyeing roller, a dewatering roller, and a hot air duct. A reversing roller is located on the inner wall of the dyeing chamber outside the feed inlet between the dyeing chamber and the drying chamber. The hot air duct is obliquely located on the inner wall of the drying chamber outside the feed inlet. The control panel is located on the front surface of the machine body above the heating box. This utility model, with its drive rollers and re-dyeing rollers, ensures reliable fabric feeding while employing a repeated immersion dyeing structure to achieve dyeing, guaranteeing the quality of the dyed fabric. The two sets of hot air ducts ensure drying efficiency while ensuring uniform heating on both sides of the fabric, improving overall dyeing efficiency and resulting in good performance.

[0004] While the existing technology CN215947609U has many advantages in use, it still has the following problems: the mixing of dyes is not perfect, which leads to the phenomenon of dye layering and precipitation inside the dyeing vat, affecting the dyeing quality of the fabric inside the dyeing vat. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a dyeing vat for dyeing recycled polyester.

[0006] The technical solution adopted by this utility model to solve its technical problem is a dyeing vat for dyeing recycled polyester, including a dyeing vat body, an air pipe and a connecting frame. A support frame is installed on the upper outer wall of the dyeing vat body. An air pipe is rotatably installed on one side of the lower inner wall of the dyeing vat body. A driven wheel is installed on one side of the outer wall of the air pipe. A connecting frame is welded to the upper outer wall of the air pipe. A connecting groove is opened inside the connecting frame.

[0007] By adopting the above technical solution, the support frame restricts the position of the guide roller, and the gas can be transported to the inside of the connecting tank through the air pipe. The air pipe can be driven to rotate through the driven wheel, which can adjust the position of the connecting frame inside the dyeing vat body.

[0008] Specifically, the upper end of the inner wall of the support frame is welded with an extension plate distributed in a rectangular array, and guide rollers are rotatably installed on both outer walls of the extension plates, with one side of the guide roller located inside the dyeing vat body.

[0009] By adopting the above technical solutions, the design of the extension plate and guide roller helps to guide the polyester material to be dyed smoothly into and out of the dyeing vat, reducing friction and damage to the material during the dyeing process.

[0010] Specifically, the connecting frame adopts an L-shaped design and is located inside the dyeing vat body.

[0011] By adopting the above technical solution, the L-shaped connecting frame design allows it to better adapt to the internal structure of the dyeing vat body, preventing the rotation of the connecting frame inside the dyeing vat body from being blocked by the extension plate, thus ensuring the smooth rotation of the connecting frame.

[0012] Specifically, a scraper is fixedly attached to the outer wall of the connecting frame, and the scraper is in contact with the outer wall of the dyeing vat.

[0013] By adopting the above technical solution, the scraper design helps to remove the precipitated dye on the inner wall of the dyeing vat and can turn over the layered or precipitated dye.

[0014] Specifically, a driving mechanism is provided on one side of the lower outer wall of the dyeing vat body. The driving mechanism consists of a fixed frame, a servo motor and a drive wheel. The fixed frame is bolted to the lower outer wall of the dyeing vat body. The drive wheel is rotatably installed inside the fixed frame. The servo motor is installed on the lower outer wall of the fixed frame. The servo motor is connected to the drive wheel. The drive wheel meshes with the driven wheel.

[0015] By adopting the above technical solution, the design of the drive mechanism enables the ventilation pipe to rotate automatically. The use of the servo motor provides precise control, allowing the rotation speed and direction of the ventilation pipe to be adjusted as needed. The meshing of the drive wheel and the driven wheel ensures the stable rotation of the ventilation pipe. It can adjust the position of the connecting frame, cooperate with the scraper to scrape and clean the inner wall of the dyeing vat, and adjust the exhaust position of the exhaust port.

[0016] Specifically, a rotary joint is inserted and installed on the outer wall of the lower end of the vent pipe, and the rotary joint is connected to the inside of the connecting groove through the vent pipe.

[0017] By adopting the above technical solution, the installation of the rotary joint allows the vent pipe to maintain communication with the external air pump's delivery pipe while rotating, ensuring continuous gas transmission. The external air pump can deliver gas to the inside of the vent pipe through the delivery pipe and the rotary joint.

[0018] Specifically, the inner wall of the connecting groove is provided with equally spaced parallel exhaust holes, and a one-way valve is provided on one side of the inner wall of the exhaust hole.

[0019] By adopting the above technical solution, the equidistant parallel exhaust holes ensure the uniform distribution of gas inside the dyeing vat body, allowing the gas inside the connecting tank to enter the dyeing vat body through the exhaust holes. Due to the upward movement of dye inside the dyeing vat body caused by the gas bubbles, the dyes at different levels can be mixed, which helps to achieve uniform mixing of dyes and avoids dye stratification. The one-way valve can prevent gas backflow, ensure the directionality of gas flow, and prevent dyes inside the dyeing vat body from flowing into the connecting tank.

[0020] The beneficial effects of this utility model are:

[0021] (1) The dyeing vat for dyeing recycled polyester described in this utility model can push up the dye that has settled or accumulated at the lower end of the dyeing vat body, avoid dye sedimentation, and ensure the integrity of pushing up the dye inside the dyeing vat body, and ensure uniform mixing of dye.

[0022] (2) The dyeing vat for dyeing recycled polyester described in this utility model can make the gas bubbles rise in the dye, thereby promoting the mixing of the dye, ensuring the uniformity of dye mixing inside the dyeing vat body, avoiding the phenomenon of dye layering, and ensuring the dyeing quality of the fabric.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the dyeing vat for dyeing recycled polyester according to this utility model includes a dyeing vat body 1, an air pipe 2, and a connecting frame 23. A support frame 11 is installed on the upper outer wall of the dyeing vat body 1. An air pipe 2 is rotatably installed on one side of the lower inner wall of the dyeing vat body 1. A driven wheel 21 is installed on one side of the outer wall of the air pipe 2. A connecting frame 23 is welded to the upper outer wall of the air pipe 2. A connecting groove 24 is opened inside the connecting frame 23.

[0032] In use, the support frame 11 restricts the position of the guide roller 13, and the gas can be delivered to the inside of the connecting groove 24 through the air pipe 2. The air pipe 2 can be driven to rotate through the driven wheel 21, which can adjust the position of the connecting frame 23 inside the dyeing vat body 1.

[0033] For guidance, exemplified, such as Figure 3 As shown, an extension plate 12 with a rectangular array is welded to the upper end of the inner wall of the support frame 11. Guide rollers 13 are rotatably installed on both outer walls of the extension plate 12, and one side of the guide roller 13 is located inside the dyeing vat body 1.

[0034] When in use, the design of the extension plate 12 and the guide roller 13 helps to guide the polyester material to be dyed smoothly into and out of the dyeing vat body 1, reducing friction and damage to the material during the dyeing process.

[0035] For smooth rotation, for example, such as Figure 1 As shown, the connecting frame 23 adopts an L-shaped design and is located inside the dyeing vat body 1.

[0036] When in use, the L-shaped connecting frame 23 is designed to better adapt to the internal structure of the dyeing vat body 1, and avoids the rotation of the connecting frame 23 inside the dyeing vat body 1 being blocked by the extension plate 12, thus ensuring the smooth rotation of the connecting frame 23.

[0037] For scraping, for example, such as Figure 4 As shown, a scraper 27 is fixedly attached to the outer wall of the connecting frame 23, and the scraper 27 is in contact with the outer wall of the dyeing vat body 1.

[0038] When in use, the scraper 27 is designed to help remove the precipitated dye on the inner wall of the dyeing vat body 1 and can turn over the layered or precipitated dye.

[0039] To drive rotation, for example, such as Figure 5 As shown, a drive mechanism 14 is provided on one side of the lower outer wall of the dyeing vat body 1. The drive mechanism 14 consists of a fixed frame, a servo motor and a drive wheel. The fixed frame is bolted to the lower outer wall of the dyeing vat body 1. The drive wheel is rotatably installed inside the fixed frame. The servo motor is installed on the lower outer wall of the fixed frame. The servo motor is connected to the drive wheel. The drive wheel meshes with the driven wheel 21.

[0040] During use, the design of the drive mechanism 14 allows the ventilation pipe 2 to rotate automatically. The use of the servo motor provides precise control, allowing the rotation speed and direction of the ventilation pipe 2 to be adjusted as needed. The meshing of the drive wheel and the driven wheel 21 ensures the stable rotation of the ventilation pipe 2. It can adjust the position of the connecting frame 23, and can work with the scraper 27 to scrape and clean the inner wall of the dyeing vat body 1, and adjust the exhaust position of the exhaust port 25.

[0041] For the purpose of gas delivery, for example, such as Figure 5 As shown, a rotary joint 22 is inserted and installed on the outer wall of the lower end of the vent pipe 2. The rotary joint 22 is connected to the inside of the connecting groove 24 through the vent pipe 2.

[0042] During use, the installation of the rotary joint 22 allows the vent pipe 2 to maintain communication with the external air pump's air delivery pipe while rotating, ensuring continuous gas transmission. The external air pump can deliver gas to the inside of the vent pipe 2 through the air delivery pipe and the rotary joint 22.

[0043] For the purpose of venting, for example, such as Figure 4 As shown, the inner wall of the connecting groove 24 is provided with equidistant parallel exhaust holes 25, and a one-way valve 26 is provided on one side of the inner wall of the exhaust hole 25.

[0044] During use, the equally spaced parallel exhaust holes 25 ensure the uniform distribution of gas inside the dyeing vat body 1, allowing the gas inside the connecting tank 24 to enter the dyeing vat body 1 through the exhaust holes 25. Due to the upward movement of the dye inside the dyeing vat body 1 caused by the gas bubbles, the dyes at different levels can be mixed, which helps to achieve uniform mixing of the dyes and prevents dye stratification. The one-way valve 26 prevents backflow of gas, ensures the directionality of gas flow, and prevents the dye inside the dyeing vat body 1 from flowing into the connecting tank 24.

[0045] When using this invention, the polyester fabric to be dyed is smoothly placed into the dyeing vat body 1 through the guide roller 13, and an appropriate amount of dye and solvent is added into the dyeing vat body 1 according to the dyeing requirements. The external material receiving mechanism can roll up the polyester fabric, so that the polyester fabric can be repeatedly dyed inside the dyeing vat body 1 through the guide roller 13.

[0046] Start the servo motor, which drives the driven wheel 21 through the active wheel, so that the air pipe 2 starts to rotate on the lower side of the inner wall of the dyeing vat body 1. The rotation of the air pipe 2 drives the connecting frame 23 and the scraper 27 to rotate together. During the rotation, the scraper 27 continuously scrapes off the precipitated dye on the inner wall of the dyeing vat body 1, further promoting the uniform mixing of dye.

[0047] An external air pump delivers gas into the vent pipe 2 through the air supply pipe and rotary joint 22. The gas enters the connecting groove 24 of the connecting frame 23 through the vent pipe 2, and then is evenly discharged through the equally spaced parallel exhaust holes 25. The one-way valve 26 on the inner wall of the exhaust hole 25 ensures unidirectional gas flow and prevents dye backflow. The gas generates bubbles inside the dyeing vat body 1. These bubbles drive the dye to move upward inside the dyeing vat, which helps the dyes at different levels to mix.

[0048] It should be noted that this utility model is a dyeing vat for dyeing recycled polyester. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
