Description

Technical Field

[0001] The utility model relates to the field of textile machinery, and more specifically, to a cotton blending device. Background Art

[0002] A blending machine is designed to uniformly mix fibers of different types and physical and chemical properties according to a specific recipe ratio to produce a fiber blend that meets specific requirements. Existing advanced blending machine designs typically feature multiple independent chambers for storing and metering different fiber types. Each chamber is equipped with a precise metering device that controls the amount of fiber released according to a preset recipe ratio. When the blending machine begins operation, the fibers in each chamber are released one by one or simultaneously according to the calculated ratio, and the fibers fall under gravity onto the conveyor belt below. Because the amounts of different fibers in the recipe often vary, and their physical properties (such as density, length, and electrostatic attraction) also affect their falling speed and distribution, the timing and location of the fibers upon falling onto the belt vary. In particular, when a larger amount of fiber is released simultaneously or nearly simultaneously with a smaller amount of fiber, the larger amount may form a continuous layer on the belt more quickly due to its superior number, while the smaller amount may be more dispersed or aggregated in some areas while being relatively sparse in others. This uneven distribution is carried into the mixing chamber as the belt moves, leading to local differences in the fiber ratios at the front and rear of the mixing chamber. If this difference is not controlled, it may affect the uniformity and quality consistency of the final product. Utility Model Content

[0023] Embodiment: A cotton mixing device, which includes a cotton storage chamber 1; a hopper 2 is arranged below the cotton storage chamber 1; a premixing chamber 3 is arranged below the hopper 2; a conveyor belt 4 is arranged at the bottom of the premixing chamber 3; the conveyor belt 4 is connected to the mixing chamber 5; a stirring device is arranged in the premixing chamber 3; the stirring device includes a driving mechanism and a stirring mechanism 7; the driving mechanism includes a driving motor 9 and a rotating mechanism; the rotating mechanism includes an active mechanism 6; the active mechanism 6 includes an active ring gear 60, an active gear 63, a first stirring gear 61 and a second stirring gear 62; the active ring gear 60 is connected to the wall of the premixing chamber 3; the active gear 63 is arranged in the middle of the active ring gear 60; the first stirring gear 61 and the second stirring gear 62 are symmetrically arranged along the active gear 63; the first stirring gear 61 and the second stirring gear 62 are respectively engaged with the active ring gear 60 and the active gear 63; the stirring mechanism 7 includes a first stirring roller 71 and a second stirring roller; the first stirring rod is connected to the first stirring gear 61; the second stirring rod 72 is connected to the second stirring gear 62.

[0024] Different types of fiber raw materials are stored separately in the cotton storage chamber 1. When the cotton mixing process begins, the raw materials fall from the cotton storage chamber 1 into the hopper 2 below under the action of gravity. The fiber raw materials in the hopper 2 continue to fall and enter the premixing chamber 3. At this time, the stirring device in the premixing chamber 3 starts to work to preliminarily mix the raw materials. The stirring device consists of a driving mechanism and a stirring mechanism 7. The driving mechanism includes a driving motor 9 and a rotating mechanism, and the rotating mechanism includes an active mechanism 6, which realizes the distribution and transmission of power through gear transmission. Specifically, the active ring gear 60 is fixed to the wall of the premixing chamber 3, and the active gear 63 is located in the middle of the active ring gear 60 and maintains a certain gap with the active ring gear 60. The first stirring gear 61 and the second stirring gear 62 are symmetrically arranged along the active gear 63 and mesh with the active ring gear 60 and the active gear 63. When the driving motor 9 is started, it drives the active gear 63 to rotate, and then through the meshing transmission between the gears, the first stirring gear 61 and the second stirring gear 62 also rotate. At the same time, the first stirring gear 61 and the second stirring gear 62 also rotate around the driving gear 63. The stirring mechanism 7 includes a first stirring roller 71 and a second stirring roller, which are connected to the first stirring gear 61 and the second stirring gear 62, respectively. As the driving gear 63 rotates, the first stirring roller 71 and the second stirring roller also rotate about their own axes and revolve around the axis of the driving gear 63. The stirring rods 73 on the stirring rollers further promote the crossing and mixing of the fibers, improving the mixing effect.

[0025] In a possible embodiment, the rotating mechanism also includes a driven mechanism 8; the driven mechanism 8 includes a driven plate 85, a first bearing 81 and a second bearing 82; the first bearing 81 and the second bearing 82 are arranged on the driven plate 85; the driven plate 85 is slidably connected to the wall of the premixing chamber 3; the first bearing 81 is connected to the first stirring roller 71; the second bearing 82 is connected to the second stirring roller; the active mechanism 6 and the driven mechanism 8 are arranged relative to each other. Through this solution, the driven plate 85 can move within a certain range to adapt to the rotation of the stirring roller and the mixing of the fibers. The first bearing 81 and the second bearing 82 are arranged on the driven plate 85 and are connected to the first stirring roller 71 and the second stirring roller. When the active mechanism 6 drives the stirring roller to rotate, the driven mechanism 8 provides stable support for the stirring roller through the bearings and ensures its smooth rotation.

[0026] In a possible embodiment, the driven mechanism 8 further includes a driven bearing 83; the driven plate 85 is connected to the bulkhead of the premixing chamber 3 via the driven bearing 83. Preferably, the active mechanism 6 further includes an active plate 64, on which a third bearing 65 and a fourth bearing are provided; the third bearing 65 and the fourth bearing are respectively sleeved on the first stirring roller 71 and the second stirring roller; the active plate 64 is slidably connected to the bulkhead of the premixing chamber 3. Preferably, the active mechanism 6 further includes an active bearing 66; the active plate 64 is connected to the bulkhead of the premixing chamber 3 via the active bearing 66. Using bearings as connectors can reduce friction increase and make rotation smoother.

[0027] In a possible embodiment, a dust cover 67 is further included; the dust cover is mounted on both ends of the first stirring roller 71 and the second stirring roller; and is used to shield the first bearing 81, the second bearing 82, the third bearing 65, and the fourth bearing. The dust cover 67 is designed to be mounted on both ends of the first stirring roller 71 and the second stirring roller, so that the first bearing 81, the second bearing 82, and the fourth bearing connected to the stirring rollers can be directly shielded. During the cotton mixing process, the fiber raw materials will be continuously stirred and mixed by the stirring rollers, and a large amount of dust and fiber debris will be generated in this process. The function of the dust cover 67 is to isolate these impurities from the outside and prevent them from entering the interior of key components such as bearings, thereby avoiding wear, jamming, and other faults. The dust cover 67 effectively prevents wear and jamming of components such as bearings, reduces the frequency of replacement due to component damage, and thus extends the service life of the equipment.

[0028] In one possible embodiment, the system further includes an active plate cover 68 and a passive plate cover 84. The active plate cover 68 is mounted on the bulkhead of the premixing chamber 3 to shield the active bearing 66, while the passive plate cover 84 is mounted on the bulkhead of the premixing chamber 3 to shield the passive bearing 83. The active plate cover is designed to be mounted on the bulkhead of the premixing chamber 3 specifically to shield the active bearing 66. Similarly, the passive plate cover 84 is also mounted on the bulkhead of the premixing chamber 3 specifically to shield the passive bearing 83. This design ensures that the bearings are adequately protected during the mixing process. During operation, the mixing and stirring of the fiber raw materials generates a large amount of dust and fiber debris. The primary function of the active plate cover 68 and the passive plate cover 84 is to isolate these impurities from the outside, preventing them from entering the active bearing 66 and the passive bearing 83, thereby preventing wear, seizure, and other problems. The plate cover design effectively prevents bearing wear and seizure, reduces the frequency of component replacement due to damage, and thus extends the service life of the equipment.

[0029] In one possible embodiment, multiple rows of stirring rods 73 are provided on the first and second stirring rollers 72. The stirring rods 73 on the first stirring roller 71 and the stirring rods 73 on the second stirring roller are spaced and aligned. Multiple rows of stirring rods 73 are provided on each of the first and second stirring rollers. These stirring rods 73 can be evenly distributed or arranged according to a specific pattern. The stirring rods 73 increase the contact area between the stirring rollers and the fiber raw material, thereby improving the mixing effect. The stirring rods 73 on the first stirring roller 71 and the stirring rods on the second stirring roller 73 remain spaced and aligned during rotation. When the two stirring rollers rotate relative to each other, the stirring rods 73 can intersect with each other, creating a "shearing" effect, further promoting the interlacing and mixing of the fibers. The rotation of the stirring rollers and the interlaced motion of the stirring rods 73 work together to ensure that the fiber raw material is thoroughly stirred and mixed within the premixing chamber 3. The design of the stirring rods 73 also helps break up fiber clumps and entanglements, improving mixing uniformity.

[0030] The beneficial effects of this embodiment are as follows: the fibers of different types and proportions falling into the premixing chamber are preliminarily mixed by the stirring device in the premixing chamber, which effectively solves the problem of uneven mixing caused by differences in fiber dosage and falling time in traditional cotton mixing machines. The stirring device can ensure that the various fibers have reached a better mixing state before entering the mixing chamber, thereby improving the uniformity of the final fiber mixture. The stirring device is powered by a drive motor, and through the cooperation of the active mechanism and the driven mechanism, the first stirring roller and the second stirring roller are rotated and stirred in the premixing chamber, which improves the quality of the cotton mixing. The transmission method of the active ring gear, the active gear, the first active gear and the second active gear, as well as the sliding connection design of the active plate and the driven plate, not only ensures the stable rotation of the stirring roller, but also facilitates maintenance and replacement of parts. At the same time, the provision of the dust cover, the active plate cover and the driven plate cover effectively prevents dust and impurities from entering key parts such as the bearings, thereby extending the service life of the equipment. By improving the uniformity of cotton blending, this technical solution helps to improve the product quality of subsequent spinning, weaving and other processes, reduce the defective rate caused by uneven mixing of raw materials, and thus improve overall production efficiency and economic benefits.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
