Description

Technical Field

[0001] This utility model relates to the field of fiber processing technology, and in particular to an automatic mixing device for dyeable flame-retardant fibers. Background Technology

[0002] Dyeable flame-retardant fiber refers to fiber material that combines good spinnability, dyeability, and flame-retardant properties. It can not only meet the requirements for dyeing effect in textile processing, but also play a flame-retardant role when exposed to fire sources, reducing fire hazards.

[0003] Dyeable flame-retardant fibers are usually composed of multiple components, including matrix fibers (such as polyester and nylon), flame retardants, dye carriers and auxiliaries. Therefore, automatic mixing devices are used to replace manual mixing, which makes the mixing more uniform. Since flame retardants and dyes may be toxic or irritating, this avoids human contact with these dangerous raw materials.

[0004] An existing publicly available technical solution, such as the automatic mixing device for dyeable flame-retardant fibers disclosed in announcement number CN213050264U, includes a mixing drum and a screw feeder. It allows for direct extraction of dyeable flame-retardant fiber raw materials from the feeding point for mixing, is easy to operate, and is suitable for widespread use.

[0005] In actual implementation, the above technical solution involves the stirring shaft rotating under the action of the stirring motor to achieve mixing. However, the stirring shaft has a simple structure and cannot move up and down inside the mixing drum. The stirring height is fixed, making it inconvenient to mix the raw materials that have settled at the bottom. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic mixing device for dyeable flame-retardant fibers. The device features a stirring shaft that can be adjusted in height while rotating normally, allowing for changes in the stirring height of the mixing rod. This facilitates the mixing of raw materials deposited at the bottom, thus solving the problems mentioned in the background section.

[0027] 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.

[0028] This utility model provides a technical solution:

[0029] Please see Figures 1 to 4 An automatic mixing device for dyeable flame-retardant fibers includes a mixing tank 1, a mixing component 4 installed inside the mixing tank 1, and a lifting component 3 installed on the mixing component 4. A cover plate 5 is installed on the top of the mixing tank 1. An inlet pipe can also be installed on the mixing tank 1, and a metering pump is installed on the inlet pipe to facilitate the addition of liquid raw materials.

[0030] The lifting assembly 3 includes lifting screws 305 disposed on the left and right sides of the mixing tank 1, and lifting brackets 304 are connected to the outside of the lifting screws 305 through screw sleeves;

[0031] The mixing component 4 includes a mixing motor 401 fixed to the top of the lifting bracket 304. The power output end of the mixing motor 401 is fixed with a mixing shaft 402, and the end of the mixing shaft 402 is fixed with a mixing rod 408.

[0032] The mixing component 4 also includes a dispersing disc 405 installed inside the mixing tank 1.

[0033] A support frame 406 is provided at the connection between the dispersing disc 405 and the mixing shaft 402, and a slide rod 410 is fixed on the top of the support frame 406. An annular groove 409 is provided at the connection between the slide rod 410 and the cover plate 5. The mixing assembly 4 also includes a guide slider 407 fixed on the surface of the mixing shaft 402, and a guide groove is provided at the connection between the guide slider 407 and the support frame 406. A collar 403 is sleeved on the outside of the mixing shaft 402, and a connecting bearing 404 is installed at the connection between the collar 403 and the cover plate 5. The mixing shaft 402 passes through the inside of the collar 403.

[0034] The lifting assembly 3 also includes fixed brackets 302 fixed on the left and right sides of the mixing tank 1, and a servo motor 301 is fixed at the bottom of the fixed brackets 302. The power output end of the servo motor 301 is fixedly connected to the lifting screw 305, and a limit plate 303 is fixed at the top of the lifting screw 305.

[0035] By adopting the above technical solution, after the raw materials enter the mixing tank 1, the servo motor 301 can drive the lifting screw 305 to rotate, and under the action of the lifting screw 305, it can drive the lifting bracket 304 to move up and down. The lifting bracket 304 can drive the mixing component 4 to move up and down, and the mixing shaft 402 can move up and down inside the collar 403. At the same time, when the mixing motor 401 drives the mixing shaft 402 to rotate, the mixing shaft 402 can drive the collar 403 to rotate inside the connecting bearing 404. The mixing rod 408 set at the bottom of the mixing shaft 402 can mix and stir the raw materials. At the same time, the mixing shaft 402 can move up and down to change the stirring height and stir the raw materials deposited at the bottom. The mixing shaft 402 rotates while the mixing shaft 402 rotates, which in turn drives the support frame 406 to rotate via the guide slider 407, thereby driving the dispersion disk 405 to rotate. The slide bar 410 on the support frame 406 can slide inside the annular groove 409 to guide the support frame 406. The mixing shaft 402, under the action of the guide slider 407, drives the dispersion disk 405 to rotate. At the same time, the mixing shaft 402 moves up and down under the action of the lifting component 3. At this time, the guide slider 407 is always located inside the support frame 406. While adjusting the height, it can also rotate normally, which can change the stirring height of the mixing rod 408, making it convenient to mix the raw materials deposited at the bottom.

[0036] Specifically, such as Figure 3As shown, a feeding assembly 2 is installed at the inlet end of the mixing tank 1. The feeding assembly 2 includes a feeding hopper 201, and a conveying pipe 202 is installed inside the feeding hopper 201. A feeding pipe 204 is fixed between the conveying pipe 202 and the mixing tank 1, and the outlet end of the feeding pipe 204 is located above the dispersing disc 405. A spiral auger 205 is rotatably installed inside the conveying pipe 202, and a conveying motor 203 is fixed at the top of the conveying pipe 202. The power output end of the conveying motor 203 is fixedly connected to the spiral auger 205. The conveying motor 203 is connected to the corresponding digital control potentiometer through an existing circuit structure. The digital control potentiometer is connected to an external power supply through a circuit. The mixing motor 401 and the servo motor 301 are connected to a relay through a circuit and are also connected to an external power supply through a circuit. The control panels of the relay and the digital control potentiometer are both installed at the front end of the mixing tank 1. The digital control potentiometer, relay, and circuit structure connected to the motor are all existing known technologies and will not be described in detail here.

[0037] By adopting the above technical solution, after the conveying motor 203 starts, it can drive the spiral auger 205 to rotate. The feed end of the conveying pipe 202 is located inside the feed hopper 201 at the lower part. The powder can enter the conveying pipe 202 through the feed hopper 201, and then be fed into the mixing tank 1 through the feed pipe 204 on the conveying pipe 202. After entering the mixing tank 1, the powder falls above the dispersing disc 405. The rotating dispersing disc 405 can disperse the powder into the mixing tank 1. The powder can be fed into the mixing tank 1 through the conveying pipe 202, and the powder can be dispersed into the mixing tank 1 in conjunction with the dispersing disc 405.

[0038] Working principle: After the conveying motor 203 starts, it drives the auger 205 to rotate. The feed end of the conveying pipe 202 is located inside the feed hopper 201, slightly below. Powder can enter the conveying pipe 202 through the feed hopper 201, and then be fed into the mixing tank 1 through the feed pipe 204 on the conveying pipe 202. After entering the mixing tank 1, the powder falls above the dispersing disc 405. The rotating dispersing disc 405 disperses the powder into the mixing tank 1. The servo motor 301 drives the lifting screw 305 to rotate, and under the action of the lifting screw 305, it drives the lifting bracket 304 to move up and down. The lifting bracket 304 can drive the mixing component 4 to move up and down. The mixing shaft 402 moves up and down inside the collar 403. At the same time, when the mixing motor 401 drives the mixing shaft 402 to rotate, the mixing shaft 402 can drive the collar 403 to rotate inside the connecting bearing 404. The mixing rod 408 set at the bottom of the mixing shaft 402 can mix and stir the raw materials. At the same time, the mixing shaft 402 can move up and down to change the stirring height and mix the raw materials deposited at the bottom. When the mixing shaft 402 rotates, it can also drive the support frame 406 to rotate through the guide slider 407, which in turn drives the dispersion disk 405 to rotate. The slide rod 410 on the support frame 406 can slide inside the annular groove 409 to guide the support frame 406.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
