Description

Technical Field

[0001] This utility model relates to the field of cotton processing technology, specifically a screening device for cotton processing. Background Technology

[0002] Cotton is a plant belonging to the genus Gossypium of the Malvaceae family. It includes upland cotton, herbaceous cotton, and tree cotton, and is an annual herbaceous or subshrub plant with sparsely covered long soft hairs on its twigs. The seeds are separable, oval, and have long white cotton hairs and short, grayish-white cotton hairs that are not easily detached. Cotton processing refers to the process of removing impurities and separating usable fibers from harvested raw cotton through a series of physical treatment steps, ultimately producing clean cotton fibers for use in textile and other industrial production. With the continuous development of cotton processing, various cotton processing devices have emerged, such as a cotton processing screening device.

[0003] A search revealed a cotton processing screening device in Chinese Utility Model Patent CN202420521459.5. The device includes a base with four symmetrically fixed support columns on its top. A housing is fixed to the top of each support column. A feed hopper is connected to the top of the housing. A rotating shaft is rotatably connected to one side wall of the housing via a bearing. A fan blade is fixed to one end of the rotating shaft inside the housing. An air inlet is located on the side wall of the housing near the fan blade. A cotton discharge pipe is connected to the side wall of the housing away from the fan blade. An auger is rotatably installed inside the bottom of the housing. This utility model, through the configuration of the housing, feed hopper, and rotating shaft... The shaft, fan blades, air inlet, cotton discharge pipe, auger, and drive assembly can easily separate cotton from sand and gravel, and facilitate the discharge of sand and gravel from the casing. It has good performance and low overall manufacturing cost. Although the equipment can easily separate cotton from sand and gravel, the fan blades are far from the cotton discharge pipe during screening, which cannot guarantee that all the cotton will be blown into the cotton discharge pipe, making screening errors easy. Some cotton will be left inside the casing and discharged with the sand and gravel, which is wasteful. Therefore, a cotton processing screening device that can blow air and vibrate to eject the sand and gravel inside the cotton is proposed, which is more efficient and less prone to screening errors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screening device for cotton processing. It has the advantages of being able to blow air and vibrate to eject sand and gravel from inside the cotton, resulting in high efficiency and less likelihood of screening errors. This solves the problem in Chinese Utility Model Patent No. CN202420521459.5, where the fan blades are too far from the cotton discharge pipe during screening, making it impossible to guarantee that all the cotton will be blown into the cotton discharge pipe, leading to screening errors and some cotton being left inside the shell and discharged with the sand and gravel, which is wasteful.

[0005] To achieve the above-mentioned purpose of blowing and vibrating to eject sand and gravel from inside cotton with high efficiency and less sieving errors, this utility model provides the following technical solution: a cotton processing sieving device, including a processing box, a feed hopper fixedly installed on the top of the processing box, and a sieving mechanism provided inside the processing box;

[0006] The screening mechanism includes a mounting box, a servo motor, a rotating rod, a fan blade, a movable rod, a movable hole, a screen plate, and a screen mesh. The mounting box is fixedly installed on the left side of the processing box. The servo motor is fixedly installed inside the mounting box. A rotating rod is provided at the output end of the servo motor. A fan blade is provided on the outer right side of the rotating rod. A movable rod is provided inside the mounting box. A movable hole is opened inside the processing box. A screen plate is hinged inside the processing box. A screen mesh is provided inside the screen plate.

[0007] Furthermore, a pulley one is fixedly installed on the outside of the rotating rod, a belt body is provided on the outer surface of the pulley one, and a pulley two is provided on the outer surface of the belt body, and the pulley two is fixedly connected to the movable rod.

[0008] Furthermore, a rubber rod is fixedly installed on the right side of the movable rod, and a limit plate is fixedly installed inside the processing box.

[0009] Furthermore, the bottom of the processing box is provided with a discharge port, and a waste frame is provided at the bottom of the processing box.

[0010] Furthermore, a discharge port is provided on the right side of the processing box, and a collection box is provided on the right side of the processing box.

[0011] Furthermore, a small motor is fixedly installed inside the feed hopper, and six feeding plates are provided at the output end of the small motor.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This cotton processing screening device, through a screening mechanism, removes sand and gravel from cotton. Cotton is placed in the feed hopper, and a small motor, started by a PLC controller, slowly rotates to discharge the cotton. A servo motor then blows the cotton to the right using fan blades, causing the sand and gravel to fall downwards. Some cotton falls onto the top of the screen, where a belt pulley assembly drives a rubber rod to continuously beat the screen, causing the upper cotton to shake and the sand and gravel to fall off. The cotton falls into a collection box for collection, while the sand and gravel fall into a waste frame through a discharge port. This screening mechanism effectively removes sand and gravel from inside the cotton through air blowing and vibration, resulting in high efficiency and reducing the likelihood of screening errors.

[0031] 4) Finally, the cotton falls into the collection box 12 for collection, and the sand and gravel fall into the waste box 10 through the discharge port 9.

[0032] In summary, this cotton processing screening device, through the screening mechanism 3, allows for the screening of cotton for sand and gravel. Cotton is placed in the feed hopper 2, and a small motor 13 is started by the PLC controller to slowly rotate and discharge the cotton. Then, a servo motor 302 is activated, and a fan blade 304 blows the cotton to the right, causing the sand and gravel to fall downwards. Some cotton falls onto the top of the screen 308, and through the belt pulley assembly, the rubber rod 7 continuously beats the screen 308, causing the cotton at the top to shake and the sand and gravel to fall. The cotton falls into the collection box 12 for collection, while the sand and gravel fall into the waste frame 10 through the discharge port 9. This screening mechanism 3 can blow air and vibrate to eject sand and gravel from inside the cotton, resulting in high efficiency and reducing the likelihood of screening errors.
