Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, and in particular to a uniform cotton feeding device for a cotton grabber. Background Technology
[0002] In the textile processing, cotton feeders, as key equipment for initial cotton opening and conveying, are widely used in spinning production lines. The uniformity of cotton feeding directly affects the stability of subsequent processes and the quality of the final product. With the increasing demands for product quality and production efficiency in textile processes, achieving continuous and stable cotton layer conveying has become a key focus of technological research and development in this field.
[0003] Currently, traditional cotton grabbers mostly use an overall adjustment method to control cotton feeding, lacking real-time monitoring and feedback adjustment functions for cotton layer thickness, making it difficult to address the problem of uneven lateral cotton layer thickness. Furthermore, existing equipment typically uses a single drive to operate multiple cotton grabbing components, failing to make precise adjustments based on localized cotton layer changes. This often results in uneven feeding in certain areas, affecting the overall cotton layer uniformity and consequently impacting product quality. Therefore, there is an urgent need for a cotton grabber uniform feeding device with real-time monitoring and intelligent adjustment functions to improve feeding accuracy and production continuity. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform cotton feeding device for a cotton grabber. This device uses an independently driven longitudinal cotton grabber and an array of pressure sensors to achieve precise adjustment of the transverse cotton feeding amount, thereby improving the uniformity of the cotton layer. At the same time, the pressure sensors provide real-time feedback on changes in cotton layer thickness and automatically adjust the height of the cotton suction hood to ensure stable cotton suction, thereby improving product quality and production continuity.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cotton-feeding device for a cotton-grabbing machine, comprising a cotton-piling platform, an outer ring wall plate fixedly connected to the outer side of the upper end of the cotton-piling platform, an inner ring wall plate fixedly connected to the middle of the cotton-piling platform, a column rotatably connected to the middle of the inner ring wall plate, a crossbeam fixedly connected to the upper end of the column, a bracket fixedly connected to the upper end of the crossbeam, a cotton-suction hood connected to the lower end of the bracket via a telescopic component, several motors fixedly connected to the front side of the cotton-suction hood, a cotton-grabbing beater fixedly connected to the motor drive end, a cotton-feeding curtain fixedly connected to one side of the lower end of the cotton-suction hood, and several pressure sensors fixedly connected to the inner side of the cotton-feeding curtain.
[0006] Furthermore, the telescopic assembly includes a corrugated telescopic tube fixedly connected to the middle of the lower end of the bracket, an electric telescopic rod fixedly connected around the lower end of the bracket, an installation block fixedly connected to the drive end of the electric telescopic rod, the installation block fixedly connected to the outer wall of the cotton suction cover, and the lower end of the corrugated telescopic tube fixedly connected to the upper end of the cotton suction cover.
[0007] Furthermore, a trolley is fixedly connected to the left end of the crossbeam, and a drive wheel is provided at the lower end of the trolley.
[0008] Furthermore, an air duct is fixedly connected to the upper end of the corrugated telescopic pipe, and a conveying pipe is rotatably connected to the upper end of the air duct.
[0009] Furthermore, the trolley is located on the outside of the outer ring wall panel, and a control device is installed on the trolley.
[0010] Furthermore, a lifting port is provided in the middle of the crossbeam to facilitate the lifting and lowering of the cotton suction cover.
[0011] Furthermore, the cotton feeding curtain is made of silicone, and the pressure sensor is a miniature array type.
[0012] This utility model has the following beneficial effects: 1. In this invention, the device employs independently driven cotton-grabbing beaters arranged longitudinally, combined with pressure sensors to detect lateral thickness differences in the cotton layer. It intelligently adjusts the rotation speed of each beater, achieving precise control of local cotton feeding without adjusting the overall system. This not only avoids the overall adjustment problems caused by local unevenness in traditional processes but also significantly improves the uniformity of the cotton layer, ensuring product quality and production efficiency.
[0013] 2. In this invention, by installing an array of pressure sensors inside the cotton feeding curtain, changes in the cotton layer thickness can be monitored in real time, and the signals are fed back to the control system to automatically adjust the working state of the electric telescopic rod, thereby driving the cotton suction hood to move up and down to maintain a suitable cotton suction height. This function effectively addresses fluctuations in cotton layer thickness, ensuring the continuity and stability of cotton conveying. Attached Figure Description

Detailed Implementation
[0016] 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.
[0017] Reference Figures 1-3 This utility model provides an embodiment of a cotton-feeding device for a cotton grabber, comprising a cotton-stacking platform 1, an outer ring wall plate 2 fixedly connected to the outer side of the upper end of the cotton-stacking platform 1, an inner ring wall plate 3 fixedly connected to the middle of the cotton-stacking platform 1, a column 4 rotatably connected to the middle of the inner ring wall plate 3, a crossbeam 5 fixedly connected to the upper end of the column 4, a trolley 6 fixedly connected to the left end of the crossbeam 5, a drive wheel 7 provided at the lower end of the trolley 6, the trolley 6 being located outside the outer ring wall plate 2, a control device provided on the trolley 6, a bracket 8 fixedly connected to the upper end of the crossbeam 5, a corrugated telescopic tube 16 fixedly connected to the middle of the lower end of the bracket 8, and an electric telescopic rod 9 fixedly connected around the lower end of the bracket 8, the electric telescopic rod 9 having a drive end A mounting block 10 is fixedly connected to the outer wall of the cotton suction cover 11. The lower end of the corrugated telescopic tube 16 is fixedly connected to the upper end of the cotton suction cover 11. Several motors 12 are fixedly connected to the front side of the cotton suction cover 11. A cotton grabbing handle 13 is fixedly connected to the drive end of the motors 12. A cotton feeding curtain 14 is fixedly connected to one side of the lower end of the cotton suction cover 11. The cotton feeding curtain 14 is made of silicone. Several pressure sensors 15 are fixedly connected to the inner side of the cotton feeding curtain 14. The pressure sensors 15 are miniature array type. A lifting port is opened in the middle of the crossbeam 5 to meet the lifting and lowering of the cotton suction cover 11. An air duct 17 is fixedly connected to the upper end of the corrugated telescopic tube 16. A conveying pipe 18 is rotatably connected to the upper end of the air duct 17.
[0018] Specifically, when using this device, the cotton material is first evenly piled on the cotton piling platform 1. The drive system is activated via the control panel on the trolley 6, causing the trolley 6 to move in a circular motion around the column 4, thus achieving omnidirectional gripping of the cotton pile. Simultaneously, the motor 12 starts, driving the cotton-grabbing beater 13 to rotate at high speed, grabbing the cotton lint from the cotton pile and sending it into the cotton suction hood 11. A fan is installed in the duct system 17, creating a negative pressure environment inside the duct, sucking the cotton lint from the suction hood 11 and conveying it to the subsequent conveying pipe 18, completing the continuous conveying of the cotton lint. An array of pressure sensors 15 is installed on the inner side of the cotton feeding curtain 14 to monitor changes in the cotton layer thickness in real time. When the pressure sensor 15 detects a change in the cotton layer thickness, the system automatically adjusts the working state of the electric telescopic rod 9, driving the cotton suction hood 11 to move up and down to maintain a suitable suction height, thereby ensuring stable cotton suction. During this process, the corrugated telescopic tube 16 extends accordingly as the cotton suction hood 11 moves downwards, ensuring the system's sealing and flexibility. Specifically, the cotton-grabbing beaters 13 of this device are arranged longitudinally, and each beater 13 is driven by an independent motor 12. Pressure sensors 15 are arranged laterally in sections, corresponding spatially to the beaters 13. When the array of pressure sensors 15 detects a difference in cotton layer thickness on the left and right sides, the system intelligently adjusts the rotation speed of the beaters 13, thereby achieving a uniform distribution of cotton feed in the transverse cross-section. This control method effectively avoids the problem of needing overall adjustment due to local unevenness in traditional processes, significantly improving cotton layer uniformity and control accuracy, and further enhancing product quality and production efficiency.
[0019] Working principle: When using this device, cotton is piled on the cotton stacking platform 1. The control device on the trolley 6 starts the drive wheel 7 of the trolley 6, causing the trolley 6 to move in a circle around the column 4. Simultaneously, the motor 12 starts, driving the cotton grabber 13 to rotate, grabbing the cotton fibers and drawing them into the cotton suction hood 11. A fan in the duct 17 creates negative pressure inside the duct, sucking up the cotton fibers in the suction hood 11 and transferring them to the conveying pipe 18. The pressure sensor 15 inside the cotton curtain 14 detects the pressure applied to the cotton curtain 14 to sense changes in the cotton layer thickness, thereby controlling the electric telescopic rod 9 to drive the cotton suction hood 11 downwards to ensure sufficient cotton suction. The corrugated telescopic tube 16 extends accordingly. Since the pressure sensor 15 is an array, when the pressure sensor 15 detects that the cotton layer thickness on the left and right sides of the cotton curtain 14 is different, it will control the rotation speed of the cotton grabber 13, thereby achieving uniformity of cotton feeding in the transverse section, solving the problem of forced overall adjustment due to local unevenness, and greatly improving the uniformity control accuracy.
[0020] It is worth noting that the circuits, protection, and sealing involved in the above embodiments are all based on the corresponding existing technologies according to the actual situation, and therefore will not be described in detail in the embodiments of this application.
