Description

Technical Field

[0001] This utility model belongs to the field of cotton spinning application equipment, and in particular relates to a cotton blending device for cotton spinning production. Background Technology

[0002] In the preparation process of spinning, a blending machine is used to thoroughly mix raw cotton or chemical fibers of different compositions in a certain proportion, making the composition and properties of the raw materials more uniform and ensuring the stability and consistency of the subsequent yarn quality. For example, mixing cotton from different origins and of different grades effectively avoids yarn quality fluctuations caused by differences in raw materials.

[0003] Currently, cotton blending machines are mainly classified into multi-compartment cotton blending machines and single-compartment cotton blending machines according to the number of compartments. Since multi-compartment cotton blending machines have more stable output than single-compartment cotton blending machines, they have become the preferred choice for most textile companies.

[0004] The existing multi-compartment cotton blending machine includes a machine casing and a cotton storage compartment. The cotton storage compartment adopts a multi-compartment structure. A cotton distribution channel is set above the cotton storage compartment, and a cotton inlet is set at the front of the cotton distribution channel. The raw cotton, which has been preliminarily loosened, enters the cotton distribution channel through the cotton inlet, and then the raw cotton is fed into the compartments one by one. At the same time, the side wall of the cotton storage compartment is provided with evenly distributed mesh holes. A fan blows air into the cotton storage compartment, which disperses the raw cotton under the action of the air force to achieve the purpose of cotton blending. Rollers and beaters are set on the lower inner side of each compartment of the cotton storage compartment. The beaters are located directly below the rollers, and a cotton conveying curtain is set below the beaters to convey the blended raw cotton. A cotton outlet is set at the bottom rear side of the cotton storage compartment.

[0005] While the above methods can achieve the purpose of blending cotton to a certain extent, the raw cotton contains large clumps that are difficult to disperse by wind. Although there is subsequent processing by luoda and beaters, the cotton can only be dispersed locally and is difficult to mix with other raw cotton, thus affecting the subsequent quality. Utility Model Content

[0006] This utility model addresses the technical problems existing in multi-compartment cotton blending machines by proposing a cotton blending device for cotton spinning production that is reasonably designed, simple in structure, easy to process, and capable of processing cotton clumps.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a cotton blending device for cotton spinning production, including a machine housing and a cotton storage bin disposed within the machine housing. The machine housing contains several adjacent cotton storage bins. Mesh holes are evenly distributed on the side walls of each cotton storage bin. A beater is located below each cotton storage bin. A cotton-dispersing roller is also disposed within the cotton storage bin. The cotton-dispersing roller is rotatably disposed within the cotton storage bin. The cotton-dispersing roller includes an upper cotton-dispersing roller and a lower cotton-dispersing roller disposed vertically. Both the upper and lower cotton-dispersing rollers include a roller body and cotton-dispersing needles evenly distributed on the roller body. The cotton-dispersing needles are conical in shape.

[0008] Preferably, the cotton-loosening roller and the beater are arranged in parallel.

[0009] Preferably, the lower cotton-dispersing roller is located near the center of the cotton storage bin, and cotton-dispersing blades are fitted onto one end of the lower cotton-dispersing roller body in a ring-shaped and uniform manner at one end of the lower cotton-dispersing roller body.

[0010] Preferably, the upper cotton-loosening roller body is provided with a deflecting blade in the middle, the deflecting blade is arranged in an arc-shaped plate shape, and the deflecting blade is uniformly and annularly fitted in the middle of the upper cotton-loosening roller body.

[0011] Preferably, the cotton-loosening needles are arranged at uneven heights on the roller body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. This utility model provides a cotton blending device for cotton spinning production. By adding a rotating cotton-dispersing roller to the existing cotton storage silo, the cotton clumps are dispersed by cotton-dispersing needles arranged at varying heights on the cotton-dispersing roller, thereby further ensuring the uniformity of the blend. At the same time, this utility model has a simple structure, is easy to process, and can be improved on the basis of the existing technology, making it suitable for large-scale promotion and use.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figures 1-3 As shown, this embodiment aims to solve the technical problem that existing multi-compartment cotton blending machines cannot effectively handle cotton clumps. To this end, the cotton blending device for cotton spinning production provided in this embodiment includes a machine housing 1 and a cotton storage bin 2 disposed inside the machine housing 1. Several adjacent cotton storage bins 2 are disposed inside the machine housing 1. Mesh holes 21 are provided on the side walls of the cotton storage bins 2. The mesh holes 21 are evenly distributed on the side walls of the cotton storage bins 2. A beater 3 is disposed below the cotton storage bins 2. The above structure is a common structure of existing multi-compartment cotton blending machines. Therefore, it will not be described in detail in this embodiment.

[0022] Considering that the main reason why cotton clumps cannot be effectively processed is that the wind cannot disperse them, thus failing to achieve the purpose of cotton mixing, in this embodiment, a cotton-dispersing roller is also provided in the cotton storage bin 2. The cotton-dispersing roller is rotatably arranged in the cotton storage bin 2. In this embodiment, in order to save power, the cotton-dispersing roller and the beater 3 are arranged in parallel, that is, the axial direction of the cotton-dispersing roller and the beater 3 is the same. In this way, the connection between the two is achieved by using a chain, and they can share the same drive mechanism.

[0023] In order to achieve better cotton dispersion, in this embodiment, the cotton dispersion roller includes an upper cotton dispersion roller 4 and a lower cotton dispersion roller 5 arranged vertically. The upper cotton dispersion roller 4 is arranged close to the top of the cotton storage bin 2. In this way, the cotton entering through the gate is first dispersed by the upper cotton dispersion roller 4 and then dispersed by the wind, resulting in a better mixing effect.

[0024] To break up cotton clumps, both the upper cotton-loosening roller 4 and the lower cotton-loosening roller 5 include a roller body and cotton-loosening needles 6 evenly distributed on the roller body. The cotton-loosening needles 6 are conical in shape. The conical shape of the cotton-loosening needles 6, rather than the more robust square shape, is primarily due to the softness of cotton itself; the ends of the cotton-loosening needles 6 can better hook onto some of the cotton, thus breaking up the cotton clumps. Simultaneously, considering that the cotton moves erratically within the cotton storage bin 2 under the influence of wind, the cotton-loosening needles 6 are unevenly arranged on the roller body to accommodate the movement of different parts of the cotton clumps.

[0025] To further improve the cotton-loosening effect, in this embodiment, the lower cotton-loosening roller 5 is positioned near the center of the cotton storage bin 2, and a cotton-loosening blade 51 is fitted onto one end of the roller body. The cotton-loosening blade 51 is mainly designed to increase the airflow. Therefore, the cotton-loosening blade 51 is a spiral fan blade, and it is only positioned at one end to avoid the airflow generated at both ends colliding with each other, which would reduce the effect. For this reason, the cotton-loosening blade 51 is uniformly fitted into a ring at one end of the roller body of the lower cotton-loosening roller 5. In this way, the airflow generated by the cotton-loosening blade 51 cooperates and collides with the airflow blown by the mesh holes 21, further disrupting the direction of the airflow and thus improving the mixing effect.

[0026] Similarly, to generate airflow, a deflecting blade 41 is installed in the middle of the upper cotton-dispersing roller 4. The deflecting blade 41 is arranged in an arc-shaped plate and is uniformly and circularly fitted in the middle of the upper cotton-dispersing roller 4. Since the upper cotton-dispersing roller 4 is located at the top of the cotton storage bin 2, it needs to disperse air downwards. Therefore, the deflecting blade 41 is arranged in an arc-shaped plate. In this way, by utilizing the airflow from the upper cotton-dispersing roller 4 and the lower cotton-dispersing roller 5, the airflow direction is further disrupted, thereby making the cotton movement more chaotic and further improving the mixing effect.

[0027] With the above-described configuration, the cotton blending device for cotton spinning production provided in this embodiment effectively processes cotton clumps within the cotton storage bin, ensuring the dispersion of the cotton clumps and thus achieving the purpose of effective cotton blending.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
