Description

Technical Field

[0001] This utility model belongs to the field of textile processing equipment, and in particular relates to a uniform feeding device for cotton yarn processing. Background Technology

[0002] The core of cotton yarn processing is divided into four main stages, including the spinning preparation stage, the spinning stage, the post-processing stage, and the finished product finishing stage. The core of the spinning preparation stage is to process the raw cotton, remove impurities, and comb the fibers, including processes such as opening, carding, drawing, and roving.

[0003] In the cotton cleaning process, cotton is conveyed to the cleaning machine via an air conveyor. The cleaning machine uses mechanical force to break up cotton clumps, remove impurities, and simultaneously perform preliminary fiber combing. However, due to the lack of mechanical pressure in the feeding direction of the cleaning machine, the cotton's downward momentum is insufficient. Combined with the dispersing effect of the airflow, this can lead to uneven cotton feeding. This makes it difficult to control the uniformity of the cotton layer conveyed from the cleaning machine to the carding machine, which in turn affects the carding quality and the efficiency of subsequent roving-to-spinning processes. Utility Model Content

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with 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. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0014] 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.

[0015] Examples, such as Figures 1-5 As shown, this utility model provides a uniform feeding device for cotton yarn processing, including a cotton cleaner 1. An airflow conveying pipe 2 is provided at the top of the cotton cleaner 1. A wastewater discharge hopper 3 and a cotton discharge hopper 4 are respectively provided on both sides of the cotton cleaner 1. A belt conveyor 5 is provided below the cotton discharge hopper 4. A distributor 6 is located in the upper part of the cotton cleaner 1. The distributor 6 includes a vertical guide plate 61 and a guide rod 62 connected to the guide plate 61. The left and right ends of the guide plate 61 are connected to the vertical inner wall of the cotton cleaner 1. The guide plate can be designed with openings to ensure the continuity of airflow inside the cotton cleaner 1, which is beneficial for the full distribution of cotton. The guide rod 62 extends towards the center of the airflow conveying pipe 2. A set of feeding pressure roller assemblies 7 are provided on both sides of the distributor 6. The driving end of the feeding pressure roller assembly 7 is provided with a lifting drive mechanism 8 connected to it. The feeding pressure roller assembly 7 includes an upper pressure roller 71 and a lower pressure roller 72 that are staggered. At least one connecting rod 73 is provided between the upper pressure roller 71 and the lower pressure roller 72. The connecting rod 73 fixes the upper pressure roller 71 and the lower pressure roller 72 by screws or direct welding, so that the lifting and lowering actions of the upper pressure roller 71 and the lower pressure roller 72 are synchronized. The upper pressure roller 71 is set close to the guide plate 61, and the lower pressure roller 72 is set away from the guide plate 61.

[0016] Specifically, the impurities removed by the cotton cleaner 1 are discharged from the waste hopper 3, while the cleaned cotton is discharged from the cotton outlet hopper 4 onto the belt conveyor 5. The belt conveyor 5 then transports the cotton processed by the cotton cleaner 1 to the carding machine for subsequent carding and roving spinning processes. The guide plate 61 serves two purposes: firstly, it diverts the cotton located in the upper part of the cotton cleaner 1, allowing the feed roller assembly 7 to effectively press down on the cotton; secondly, the guide plate 61 supports the guide rod 62, ensuring that the guide rod 62 is positioned within the airflow conveying pipe. 2. The airflow conveying channel 2 includes a box-type hopper connected to the cotton cleaner 1. A cylindrical pipe is provided at the end of the box-type hopper. The guide rod 62 extends from the top of the guide plate 61 in a "F" shape through the box-type hopper, and then extends for 1-2m in the cylindrical pipe before stopping. The diameter of the guide rod 62 is no more than 1 / 3 of the diameter of the cylindrical pipe. The guide rod 62 can occupy a certain volume in the airflow conveying channel 2, which does not affect the continuous conveying of cotton flow and can reduce the dispersion of the cotton flow conveyed by the airflow. Furthermore, by using a liftable feeding roller assembly 7, the cotton in the feeding direction can be pressed down. For example, the upper roller 71 and the lower roller 72 are at different heights, which can press down the cotton at different heights. At the same time, the connecting rod 73 can also play a certain pressing role, which is conducive to improving the uniformity of feeding, thereby improving the cleaning efficiency of the cotton cleaner 1 and ensuring the spinning quality.

[0017] To improve the sealing performance of the cleaning machine 1, in conjunction with the feeding pressure roller assembly 7, the inner wall of the cleaning machine 1 provided by this invention is provided with guide grooves 9 that mate with both ends of the lower pressure roller 72, and the side of the cleaning machine 1 is provided with guide holes 10 that mate with both ends of the upper pressure roller 71. A sliding cover 11 that slidably mates with the side of the cleaning machine 1 is provided on the outer side of the guide holes 10. The guide grooves 9 do not penetrate the side wall of the cleaning machine 1, and while providing lifting guidance for the lower pressure roller 72, there is no sealing requirement. For the upper pressure roller 71, since it has a transmission connection with the lifting drive mechanism 8 located outside the cleaning machine 1, this invention uses the design of opening the guide holes 10 to provide lifting guidance for the upper pressure roller 71, while using the sliding cover 11 to achieve a movable seal at the upper and lower ends of the guide holes 10. This ensures that the feeding pressure roller assembly 7 receives effective power while also ensuring the sealing performance of the cleaning machine 1.

[0018] Furthermore, the upper pressure roller 71 provided by this utility model includes two shaft connection sections 711, with a crankshaft section 712 disposed between the shaft connection sections 711. The crankshaft section 712 has a U-shaped structure with its U-shaped opening facing downwards, and the upper and lower covering surfaces of the sliding cover 11 are used to seal the guide hole 10. The upper pressure roller 71 adopts a crankshaft design, which on the one hand allows for sufficient vertical spacing with the lower pressure roller 72, facilitating sufficient downward pressure on the cotton inside the cotton cleaner 1; on the other hand, the crankshaft design lowers the relative height of the shaft connection sections 711, reducing the horizontal level of the highest point of the guide hole 10. Therefore, by setting the connection node between the sliding cover 11 and the upper pressure roller 71 near the middle position of the sliding cover 11, the sliding cover 11 can maintain a seal on the position of the guide hole 10 during its vertical movement, thereby preventing cotton inside the cotton cleaner 1 from overflowing from the guide hole 10.

[0019] To improve the synchronization of the lifting drive mechanism 8 with the material feeding roller assembly 7, the two sets of material feeding roller assemblies 7 provided by this utility model are simultaneously connected to one set of lifting drive mechanism 8. Specifically, the sliding cover 11 is provided with a connecting block 111, and the connecting block 111 is provided with two connecting holes 112 for connecting the upper roller 71. The center of the connecting block 111 is provided with a screw thread hole. The lifting drive mechanism 8 includes a screw and a motor. The motor is located on the top of the cleaning machine 1. Bearing seats are provided at both the upper and lower ends of the screw. The bearing seats are used to ensure that the screw can rotate continuously and stably. The connecting block 111 is welded to the sliding cover 11 to form an integral unit. The two connecting holes 112 on the connecting block 111 are connected to the upper pressure rollers 71 of the two sets of feeding pressure roller assemblies 7. At the same time, the connecting block 111 acts as a lead screw slider. The threaded pair between the lead screw and the connecting block 111 can convert the rotation of the lead screw into the lifting and lowering of the connecting block 111, thereby driving the two sets of feeding pressure roller assemblies 7 to achieve effective lifting and lowering, thus completing the feeding and pressing action of the cotton inside the cotton cleaning machine 1.

[0020] To improve the moving quality of the sliding cover 11, the sliding cover 11 provided by this utility model is provided with connecting ears 113 on both sides, and the connecting ears 113 are provided with sliding holes. The cleaning machine 1 is provided with a guide rod 12 that cooperates with the sliding holes. The top of the guide rod 12 is fixedly connected to the top side of the cleaning machine 1. The sliding cooperation between the connecting ears 113 and the guide rod 12 can ensure the straightness of the sliding cover 11 during the lifting and lowering movement, which can not only ensure the moving quality of the feeding pressure roller assembly 7, but also help to ensure the sealing of both sides of the cleaning machine 1.

[0021] 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.
