Description

Technical Field

[0001] This utility model relates to the technical field of dyeing devices, specifically to a carpet yarn dyeing device with temperature control. Background Technology

[0002] In the carpet manufacturing industry, the dyeing quality of carpet yarn is one of the key factors that determine the overall aesthetics, color stability, and product grade of a carpet. Traditional carpet yarn dyeing processes have long relied on relatively simple and crude equipment and methods. As the market's requirements for carpet quality have increased, these existing methods have exposed many insurmountable drawbacks.

[0003] Existing carpet yarn dyeing methods are mainly divided into two basic types: immersion dyeing and pad dyeing. Immersion dyeing is the most common method, which involves immersing bundles of carpet yarn in a dye bath to achieve dyeing. However, conventional immersion dyeing equipment lacks an effective temperature control mechanism. On the one hand, in many dyeing formulas, a specific temperature range has a decisive influence on the dye uptake rate, evenness, and color fastness of the dye. However, traditional immersion dyeing equipment relies heavily on manual experience and rough temperature control, resulting in large fluctuations in dyeing effects and significant color differences between batches. Utility Model Content

[0004] This invention provides a carpet yarn dyeing device with temperature control, which can effectively solve the above problems.

[0005] This utility model is implemented as follows:

[0006] A carpet yarn dyeing device with temperature control, comprising:

[0007] The mounting frame has several dyeing barrels on it. Each dyeing barrel has a rotating drum for hanging yarn on top. A temperature sensor is provided on the side of the dyeing barrel. A steam heating pipe is provided at the bottom inside the dyeing barrel. The rotating drum is mounted on the mounting frame and driven by a drive mechanism. A first electrically controlled valve is provided at the input end of the steam heating pipe.

[0008] A control device is electrically connected to the drive mechanism, the temperature sensor, and the first electrically controlled valve, respectively.

[0009] As a further improvement, a groove is provided on the side wall of the dyeing barrel, and a cover is provided on the outside of the dyeing barrel. The cover is attached to the dyeing barrel and covers the groove to form a detection cavity that communicates with the inside of the dyeing barrel. The temperature sensor is inserted into the cover from the side of the cover.

[0010] As a further improvement, the drive mechanism includes a servo motor and a transmission belt, the drive motor being connected to the mounting bracket, and the transmission belt connecting the drum and the drive motor.

[0011] As a further improvement, the driving mechanism includes a drive motor and a transmission assembly, with the plurality of rotating drums connected to the transmission assembly and driven by the drive motor.

[0012] As a further improvement, the bottom of the dyeing barrel is provided with a drain outlet, and a manual valve is provided at the drain outlet.

[0013] As a further improvement, the rotating drum is provided with baffles at both ends and a placement part in the middle. The cross-section of the placement part is a polygon with the number of sides being S, where 7≤S≤10.

[0014] As a further improvement, the steam heat transfer pipe is spirally coiled around the bottom of the dyeing tank.

[0015] As a further improvement, the top of the mounting bracket is also provided with a row of hooks.

[0016] The beneficial effects of this utility model are:

[0017] The mounting frame is equipped with multiple dyeing vats, a design that allows for the simultaneous dyeing of multiple batches. Compared to traditional dyeing equipment, which may only process one or a few yarn bundles at a time, this device can process more carpet yarn bundles in the same amount of time, significantly increasing dyeing output per unit time and meeting the needs of large-scale carpet production. The rotating drum allows the yarn bundles to be partially and alternately immersed in the dyeing vats. Compared to traditional full immersion dyeing, this method allows for more thorough contact between the dye and the yarn bundles, and the rotation of the yarn bundles also agitates the dye solution, resulting in more even and thorough mixing.

[0018] A temperature sensor is installed on the side of the dyeing tank, which can collect the temperature of the dye liquor in real time. This solves the problem of the difficulty in accurately judging the temperature manually in traditional dyeing devices, allowing for precise measurement of temperature data during the dyeing process. This avoids large temperature fluctuations and unstable dyeing results, and the temperature sensor provides data support for precise temperature control. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Example 1:

[0030] Reference Figure 1-4 As shown, a carpet yarn dyeing device with temperature control includes:

[0031] Mounting frame 1 has multiple dyeing barrels 2 on it, which facilitates dyeing multiple batches at once. Each dyeing barrel 2 has a rotating drum 4 on top. The yarn for weaving carpets is hung on the rotating drum 4, and part of the yarn is immersed in the dyeing barrel 2. The rotating drum 4 is rotated so that the yarn is partially immersed in the dyeing barrel 2 in turn. A temperature sensor 3 is provided on the side of the dyeing barrel 2 to collect the temperature of the dye liquor. A steam heating pipe 9 is provided on the bottom inner side of the dyeing barrel 2. The steam heating pipe 9 is connected to an external steam device, which provides steam. The steam heating pipe 9 contacts the outer wall of the dye liquor and transfers heat to the dye liquor, thereby raising the temperature of the dye liquor. The rotating drum 4 is mounted on the mounting frame 1 through a vertical bearing seat and is driven by a drive mechanism 8 to rotate. A first electric control valve 10 is provided at the input end of the steam heating pipe 9. By controlling the opening and closing of the first electric control valve 10, the flow rate of steam in the steam heating pipe 9 in the dyeing barrel 2 is controlled, thereby controlling the temperature of the dye liquor.

[0032] The control device 5 is electrically connected to the drive mechanism 8, the temperature sensor 3 and the first solenoid valve 10 respectively. According to the program set in the control device 5, the heating rate of the dye liquor, the heating time and the rotation frequency of the drum 4 are adjusted to achieve precise control of the dyeing process of carpet yarn.

[0033] Specifically, a groove is provided on the side wall of the dyeing barrel 2, and a cover 6 is provided on the outside of the dyeing barrel 2. The cover 6 is attached to the dyeing barrel 2 and covers the groove, forming a detection cavity that communicates with the inside of the dyeing barrel 2. The temperature sensor 3 is inserted into the cover 6 from the side of the cover 6. A groove is provided to form a temperature detection cavity that communicates with the inside of the dyeing barrel 2. The temperature sensor 3 is located in the detection cavity to prevent the yarn from getting caught on the temperature sensor 3 during the dyeing and rotation process.

[0034] Specifically, the drive mechanism 8 includes a servo motor 81 and a transmission belt 82. The servo motor 81 is connected to the mounting bracket 1, and the transmission belt 82 connects the rotating drum 4 and the drive motor 81. The drive motor 81 can accurately control the rotation speed of the rotating drum 4. Moreover, in the dyeing operation environment where the temperature and humidity are relatively high, compared with metal parts transmission, belt transmission is superior in terms of cost and durability. Each drive motor 81 is individually controlled, which is convenient for different dyeing operations.

[0035] Specifically, the bottom of the dyeing tank 2 is equipped with a drain outlet, and a hand valve 11 is provided at the drain outlet to facilitate the discharge of dye liquor.

[0036] Specifically, the rotating drum 4 has baffles 41 at both ends and a placement part 42 in the middle. The cross-section of the placement part 42 is polygonal with the number of sides S, where 7≤S≤10. If S is too small, the wire bundle will be bent more by the edges when it is hung on the rotating drum 4. If S is too large, the rotating drum 4 will slip when it drives the yarn bundle to rotate. In this embodiment, S=8 is preferred.

[0037] Specifically, the steam heat transfer pipe 9 is spirally coiled around the bottom of the dyeing tank 2, giving it a longer heat exchange pipe and increasing the rate at which the dye liquor heats up.

[0038] Specifically, the top of the mounting frame 1 is also provided with a row of hooks 7, which can be used to hang the dyed or undyed bundles of thread.

[0039] Example 2:

[0040] Reference Figure 5 As shown, unlike Embodiment 1, the drive mechanism 8 is different. In this embodiment, the drive mechanism 8 includes a servo motor 81 and a transmission component 83. Several rotating drums 4 are connected to the transmission component 83. The transmission component 83 uses a transmission shaft and gears for transmission. The servo motor 81 and the rotating drums 4 rotate at the same speed without speed change. Several rotating drums are driven by a drive motor 81. Driving multiple rotating drums with a single drive motor 81 can save on device costs.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
