[0016] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0017] The invention provides an automatic cotton mixing machine for knitted fabrics.

[0018] Reference Figures 1 to 7 , including a cotton mixing mechanism 11, a conveying mechanism 12, a feeding fan 13, a cotton drop box 14, a cotton discharge box 15 and a weighing box 16. The cotton mixing mechanism 11 includes: A mixing shell 21 and a plurality of rotating drums 22, each rotating drum 22 is rotatably connected to the mixing shell 21; The gathering baffle 24 is fixedly connected to the cotton mixing housing 21 and is used to limit and gather the mixed cotton materials; The discharge pipe 23 is provided on one side of the cotton mixing housing 21 and is used to discharge the cotton fibers after the mixing is completed; The material pulling assembly is used to improve the stretching effect of each drum 22 on the cotton fibers, and the material pulling assembly is arranged in the drum 22; A linkage assembly for driving each drum 22 to rotate synchronously; The wire drawing sleeve 31 in the pulling assembly can pull the surrounding cotton fibers as the drum 22 rotates, and with the cooperation of the pneumatic assembly, the wire drawing sleeve 31 is driven to slide relative to the drum 22 along the axis of the drum 22, which can effectively enhance the pulling effect of the cotton fibers in the local area, thereby accelerating the positioning and stretching of the cotton fibers, so that the cotton fibers can be more evenly distributed, thereby improving the production efficiency of the cotton fibers. In addition, it can also improve the mixing effect between cotton fibers of different proportions, so that the cotton fibers can be more efficiently mixed and distributed during the processing process.

[0019] Reference Figures 1 to 7 , the tearing components include: The wire drawing sleeve 31 is slidably clamped on the outside of the rotating drum 22, and a plurality of wire drawing posts 32 are fixedly connected to the wire drawing sleeve 31; Pneumatic assembly, used to drive the wire drawing sleeve 31 to move; The wire drawing sleeve 31 in the pulling assembly can pull the surrounding cotton fibers as the drum 22 rotates, and with the cooperation of the pneumatic assembly, the wire drawing sleeve 31 is driven to slide relative to the drum 22 along the axis of the drum 22, which can effectively enhance the pulling effect of the cotton fibers in the local area, thereby accelerating the positioning and stretching of the cotton fibers, so that the cotton fibers can be more evenly distributed. In addition, it can also improve the mixing effect between cotton fibers of different proportions, so that the cotton fibers can be more efficiently mixed and distributed during the processing process.

[0020] Reference Figures 5 to 7 A plurality of first air holes 221 are provided in the rotating drum 22. Each first air hole 221 is arranged in a ring shape with the axis of the rotating drum 22 as the center. A second air hole 222 is provided in the rotating drum 22. The provision of the plurality of first air holes 221 allows the cotton fibers around the rotating drum 22 to be evenly affected by the airflow, thereby improving the stretching effect of the airflow on the cotton fibers. The provision of the second air holes 222 allows space for the movement of the air transfer membrane 41. The first air holes 221 prevent the air transfer membrane 41 from acting as a closed piston in the rotating drum 22, allowing the air transfer membrane 41 to move stably under the action of air pressure, thereby ensuring the stable operation of the pneumatic component.

[0021] Reference Figures 5 to 7 , pneumatic components include: The air transfer membrane 41 is slidably connected to the second air hole 222. A transmission groove 223 is formed on the inner wall of the second air hole 222. The air transfer membrane 41 is fixedly connected to the wire drawing sleeve 31 through the transmission groove 223. Two quick connectors 42, each quick connector 42 is threadedly connected to both ends of the rotating drum 22; The pneumatic assembly is connected to the trachea via a quick connector 42 on one side, and can adjust the position of the air transfer membrane 41 in the second air hole 222, thereby controlling the relative slippage between the wire drawing sleeve 31 and the rotating drum 22. When the wire drawing sleeve 31 rotates with the rotating drum 22, it pulls the cotton fibers up and down, and can also produce a pulling effect left and right. Through the reciprocating motion of the pneumatic assembly, this pulling method can effectively enhance the pulling effect of the cotton fibers in a local area, thereby accelerating the positioning and stretching of the cotton fibers, so that the cotton fibers can be more evenly distributed. In addition, it can also improve the mixing effect between cotton fibers of different ratios, so that the cotton fibers are more efficiently mixed and distributed during the processing process. Both quick connectors 42 are connected to air pipes. When air is injected into the quick connector 42 close to the linkage assembly, the air transfer membrane 41 can be driven to move in the rotating drum 22 under the action of air pressure. Since there are a plurality of first air holes 221, the gas will not be compressed, so the air transfer membrane 41 can move stably. The quick connector 42 far from the linkage assembly will not affect the movement of the air transfer membrane 41 regardless of whether air is injected or not. When the quick connector 42 close to the linkage assembly stops injecting air, a sealed cavity is formed between the air transfer membrane 41 and the quick connector 42 close to the linkage assembly, and the gas injected into the quick connector 42 far from the linkage assembly will not affect the relative position of the air transfer membrane 41.

[0022] Reference Figures 5 to 7 The inner wall of the first air hole 221 is provided with a plurality of air injection holes 224, and the wire drawing sleeve 31 is provided with a plurality of air transfer grooves 311; When the air transfer groove 311 slides relative to the wire drawing sleeve 31 and the rotating drum 22, and when the air transfer groove 311 is connected to the plurality of air injection holes 224, the gas is ejected at a high speed through the air injection holes 224, and then guided by the inner wall of the air transfer groove 311, it is blown toward the cotton fibers between two adjacent wire drawing sleeves 31, which can break the adhesion between the cotton fibers and promote the uniform distribution between the fibers. During the pulling process, the mixing effect of the cotton fibers is better, the interweaving or bundling of the cotton fibers is reduced, the consistency of the final fibers is improved, and the quality of the final product is improved, and the cotton fiber mixing effect is improved.

[0023] Reference Figure 6 The inner wall of the gas transfer groove 311 is in the shape of a trapezoidal square groove, and the notch of the inner wall of the gas transfer groove 311 is gradually enlarged toward the direction of the rotating drum 22; Through the shape design of the notch of the air transfer groove 311, the airflow can be effectively guided to avoid scattering or disordered flow of the airflow. In this way, the airflow can produce a more uniform blowing effect between the cotton fibers, thereby ensuring that the pulling process of the cotton fibers is more precise and uniform. By precisely controlling the blowing direction and intensity of the airflow, the distribution of the cotton fibers is better controlled, so that the stress and stretching state of each fiber are kept consistent, thereby greatly improving the consistency of the fiber processing process, which not only improves production efficiency, but also ensures the quality stability of the final product.

[0024] Reference Figure 4 , the linkage components include: The servo motor 51 is fixedly connected to the outside of the mixing housing 21; A plurality of first synchronous wheels 52, each first synchronous wheel 52 is fixedly connected to each rotating drum 22; A first synchronous belt 53 is sleeved on and meshed with the first synchronous wheels 52; Two second synchronous wheels 54, the two second synchronous wheels 54 are respectively fixedly connected to any one of the rotating drums 22 and the driving shaft of the servo motor 51; A second synchronous belt 55 is sleeved on the two second synchronous wheels 54 and meshes with them; The rotation and speed of the plurality of rotating drums 22 are synchronously adjusted through the linkage mechanism, so that the cotton fibers between two adjacent rotating drums 22 can be pulled in a relatively stable space, thereby improving the pulling effect of the plurality of rotating drums 22 on the cotton fibers, and further improving the effect of the equipment on pulling the cotton fibers.
