Description

Technical Field

[0001] This utility model belongs to the field of textile machinery manufacturing technology and relates to a cotton feeding device for a cotton opener. Background Technology

[0002] In the raw material pretreatment stage of the textile industry, the cotton opener, as one of the key pieces of equipment, undertakes the important task of unpacking and initially loosening compressed cotton or other fibrous materials. This process is crucial to ensuring the quality of subsequent processing steps such as carding and spinning. The cotton opener loosens the fibers through mechanical or airflow action, removing impurities and short fibers, ensuring that the fibrous material is in a suitable state for further processing. Traditional cotton openers are usually equipped with a cotton feeding device, the main function of which is to continuously and evenly feed the fibrous material to be processed into the cotton opener for processing.

[0003] However, in practical applications, existing cotton openers often encounter problems when handling fluffy cotton. Due to the high loft and volume of the cotton, the feeding device can easily clog the feeding inlet, leading to poor feeding or even machine shutdown. This not only reduces production efficiency but also frequently requires manual assistance to press and push the cotton to maintain normal operation, increasing labor costs and the workload of workers. Utility Model Content

[0004] The purpose of this invention is to provide a cotton feeding device for a cotton opener, which can ensure that cotton can be automatically and continuously fed into the cotton opener without manual intervention, thereby reducing labor costs and improving work efficiency.

[0005] To solve the above technical problems, this utility model provides a cotton feeding device for a cotton opener, including a horizontally arranged cotton feeding trough with an open top. A cotton inlet channel is connected to the upper end of one end of the cotton feeding trough. A cotton feeding port is opened at the horizontal end of the cotton inlet channel near the middle of the cotton feeding trough. A cotton inlet is opened at the end of the cotton feeding trough and the cotton inlet channel away from the cotton feeding port.

[0006] The feeding trough is movably provided with a feeding conveyor belt arranged along its length. Both ends of the feeding trough are rotatably connected with drive rollers located at both ends of the feeding conveyor belt. A drive motor is installed at one end of the feeding trough, and the power output shaft of the drive motor is connected to one end of one of the drive rollers.

[0007] The cotton inlet channel is rotatably connected to a large drive roller near the cotton feeding port and a small drive roller near the cotton inlet. The large drive roller and the small drive roller are fitted with a pressing conveyor belt. The lower side of the pressing conveyor belt gradually approaches the feeding conveyor belt from the cotton feeding port toward the cotton inlet.

[0008] By adopting the above technical solution, after the cotton material is gradually added to the cotton feeding trough, the drive motor drives the drive roller to rotate, so that the feeding conveyor belt carries the cotton material from the cotton feeding port into the cotton inlet channel. The cotton material entering the cotton inlet channel first contacts the pressing conveyor belt at the large drive roller and is gradually conveyed inward. During the process, the indirect distance between the pressing conveyor belt and the feeding conveyor belt gradually decreases, flattening the cotton material step by step, and finally outputting it from the cotton inlet into the cotton opener for opening.

[0009] The present invention is further configured such that a horizontal height limiting roller is rotatably connected to the side of the large transmission roller near the cotton feeding port in the cotton feeding channel, the horizontal height limiting roller rotates in opposite directions to the large transmission roller, and multiple circumferentially distributed outer scraper strips are provided on the outer side of the horizontal height limiting roller.

[0010] The present invention is further configured such that one end of the large transmission roller extends out of the cotton inlet channel and is provided with a transmission gear, and one end of the horizontal height limiting roller extends out of the cotton inlet channel and is provided with a driven gear that meshes with the transmission gear.

[0011] The present invention is further configured such that a drive roller extending from the cotton inlet end of the drive roller is provided with a drive gear, and a synchronization gear meshing with the drive gear is provided at one end of the small transmission roller extending from the cotton inlet channel.

[0012] The present invention is further configured such that a lower pressure roller of the same height as the small transmission roller is rotatably connected to the middle of the cotton feeding channel and the pressing conveyor belt, and the large transmission roller is higher than the lower pressure roller and the small transmission roller.

[0013] The present invention is further provided that the outer side of the feeding conveyor belt is provided with a plurality of material carrying strips distributed along its length direction.

[0014] The present invention is further configured such that a plurality of pressing strips are provided on the outer side of the pressing conveyor belt, which are distributed along its length direction.

[0015] Compared with existing technologies, this utility model uses a feeding conveyor belt and a pressing conveyor belt to gradually compact the cotton material before feeding it into the cotton opener. Compared with the traditional ordinary cotton feeding port, it can gradually push the cotton material inward through the pressing conveyor belt at the large transmission roller, effectively preventing the cotton material from blocking the cotton feeding port. It does not require manual intervention, reduces labor costs, and improves work efficiency. At the same time, the outward rotating horizontal height limiting roller can push the cotton material that is higher than the cotton feeding port backward, so that the thickness of the cotton material entering the cotton feeding channel is equal, which helps to make the subsequent cotton opening effect more uniform.

[0021] Example, refer to Figure 1-3 A cotton feeding device for a cotton opener includes a horizontally positioned feeding trough 1 with an open top. A cotton inlet channel 2 is connected to the upper end of one end of the feeding trough 1. A feeding port 3 is opened at the horizontal end of the feeding channel 2 near the middle of the feeding trough 1. A cotton inlet 4 is opened at the end of the feeding trough 1 and the feeding channel 2 away from the feeding port 3, with the cotton inlet 4 facing the interior of the cotton opener. A feeding conveyor belt 5 is movably arranged within the feeding trough 1 along its length. Several material-carrying strips 6 are arranged on the outer side of the feeding conveyor belt 5 along its length to increase the thrust on the cotton. A drive roller 7, located at both ends of the feeding conveyor belt 5, is rotatably connected to both ends of the feeding trough 1. A drive motor 8 is installed at one end of the feeding trough 1, and the power output shaft of the drive motor 8 is connected to one end of one of the drive rollers 7.

[0022] A large drive roller 9 near the cotton feed inlet 3 and a small drive roller 10 near the cotton inlet 4 are rotatably connected inside the cotton inlet channel 2. A pressing conveyor belt 11 is fitted over the large drive roller 9 and the small drive roller 10. Several pressing strips 12 are arranged along the length of the pressing conveyor belt 11 to increase the thrust of the pressing conveyor belt 11 on the cotton material. A lower pressing roller 13 of the same height as the small drive roller 10 is rotatably connected to the middle of the pressing conveyor belt 11 in the cotton inlet channel 2. The large drive roller 9 is higher than the lower pressing roller 13 and the small drive roller 10. The lower side of the pressing conveyor belt 11 gradually approaches the feeding conveyor belt 5 from the cotton feed inlet 3 towards the cotton inlet 4, until it is parallel to the feeding conveyor belt 5 after the position of the lower pressing roller 13. A drive roller 7 extending out of the cotton inlet 4 is provided with a drive gear 14, and a small transmission roller 10 extending out of the cotton inlet 2 is provided with a synchronous gear 15 that meshes with the drive gear 14, so that the pressing conveyor belt 11 can move in the same direction and synchronously with the feeding conveyor belt 5.

[0023] A horizontal height limiting roller 16 is rotatably connected to the side of the large transmission roller 9 near the cotton feeding port 3 inside the cotton feeding channel 2. One end of the large transmission roller 9 extends out of the cotton feeding channel 2 and is equipped with a transmission gear 17. One end of the horizontal height limiting roller 16 extends out of the cotton feeding channel 2 and is equipped with a driven gear 18 that meshes with the transmission gear 17, so that the horizontal height limiting roller 16 and the large transmission roller 9 rotate towards each other. Multiple circumferentially distributed outer scraper bars 19 are provided on the outer side of the horizontal height limiting roller 16, so that when the horizontal height limiting roller 16 rotates, the cotton material can be scraped outward by the outer scraper bars 19.

[0024] Working principle: After cotton material is gradually added to the cotton feeding trough 1, the drive motor 8 drives the drive roller 7 to rotate, so that the feeding conveyor belt 5 carries the cotton material from the cotton feeding port 3 into the cotton inlet channel 2. During the process, the horizontal height limiting roller 16 rotates outward, and the outer scraper 19 scrapes away the cotton material that is higher than the cotton feeding port 3, so that the thickness of the cotton material entering is uniform. The cotton material entering the cotton inlet channel 2 first contacts the pressing conveyor belt 11 at the large drive roller 9 and is gradually conveyed inward. During the process, the distance between the pressing conveyor belt 11 and the feeding conveyor belt 5 gradually decreases, flattening the cotton material step by step, and finally outputting from the cotton inlet 4 into the cotton opener for opening.
