Description

Technical Field

[0001] The utility model relates to the technical field of cotton lint and cottonseed separation, in particular to a device for separating cotton lint and cottonseed hulls. Background Art

[0002] Cottonseed is the seed of cotton. Cottonseed can be used to make salad oil and cooking oil, and can be used as shortening and margarine after hydrogenation. The cake residue or seed kernel after oil extraction can be used as poultry feed. After the cotton fiber is removed by the cotton gin, a layer of cotton lint will be left on the surface of the seed. This cotton lint can be used to make coarse yarn and a variety of fiber products, including the production of explosives, acetate fiber, rayon, ethyl cellulose, spray paint and a variety of plastics and other products that require high-quality fiber as raw materials. Therefore, how to separate cotton lint from cottonseed hulls becomes an important step in making full use of cotton seeds.

[0003] For example, the patent authorization number is CN211057052U, which is a separation device for cottonseed oil processing. When separating cotton lint, the device only separates the cotton lint on the cotton seeds by scraping it, and the scraped cotton lint will be collected on the opposite side of the two plug nets. If the amount to be processed is too large, the cotton lint will accumulate on the opposite side of the two plug nets, affecting the movement of the lint removal plate, thereby affecting the separation efficiency between the cotton lint and the cotton seeds.

[0051] The beneficial effect of adopting the above preferred solution is that the displacement of the sliding rod in the sliding groove is conducive to driving the sliding ring to move up and down, thereby pressing the cotton lint wrapped around the winding block downward into the cotton lint collecting area.

[0052] Preferably, Figure 2 As shown, the pressing mechanism 6 includes a pneumatic push rod 61 and a downward moving rod 62. The pneumatic push rod 61 is installed on the left inner wall and the right inner wall of the separation box 2, and the output shaft is connected to the downward moving rod 62.

[0058] The beneficial effect of adopting the above preferred solution is that the feed inlet is conducive to pouring the cottonseed hulls with cotton linters into the device.

[0059] The working process of the utility model is described below by an embodiment:

[0060] like Figures 1 to 6 As shown, the mixed cotton lint and cotton seeds to be separated are put into the separation box 2 through the feed port, and the two exhaust fans 8 therein work alternately. Specifically, when the exhaust fan 8 on one side is turned on, the exhaust fan 8 on the other side is in a closed state, and when the exhaust fan 8 is working, the mixed cotton lint and cotton seeds will be adsorbed and stuck on the separation roller 51 under the action of wind force, and the separation roller 51 will rotate under the action of the output motor 53. Since the two separation rollers 51 in the same cotton seed separation mechanism 5 are driven to rotate synchronously by two transmission gears 52, the rotation directions of the two separation rollers 51 are opposite at this time, so that the cottonseed shell with cotton lint can continuously change its position between the two separation rollers 51. In addition, the distance between the two separation rollers 51 is smaller than the size of the cottonseed shell, so the cotton attached to the cottonseed shell can pass through the gap between the two separation rollers 51 to reach the cotton lint separation mechanism 4, while the cottonseed shell cannot, thereby realizing the preliminary separation of cotton lint and cottonseed shell.

[0061] At the same time, the servo motor 71 will drive the translation rod 74 to do translational movement. It should be noted that during the entire movement process, the cotton lint winding and separation component 43 is constantly rotating under the action of the driving motor 41. When the translation rod 74 approaches the separation roller 51, a part of the initially separated cotton lint will be wound around the winding block 432 on the surface of the winding shaft 431. The force generated by the winding of the winding shaft 431 will further separate a part of the tightly connected cotton lint and cotton seeds. Then the translation rod 74 will do a back movement, and the sliding ring 422 set on the winding shaft 431 will move to the lower moving rod Below the separation roller 51, after the sensor detects the position of the translation rod 74, the controller will control the pneumatic push rod 61 to push the lower moving rod 62 downward. At this time, the lower moving rod 62 drives the sliding ring 422 to move downward by direct contact, thereby pushing down the cotton wool wrapped on the wrapping block 432. This can prevent the cotton wool from accumulating on one side of the separation roller 51, and after the sliding ring 422 moves downward, it will be reset by the action of the reset spring 44, and the cotton wool therein will fall into the cotton wool collecting area 12, and the cotton seeds will fall into the cotton seeds collecting area 11. By repeating this process, a large amount of mixed cotton wool and cotton seeds can be processed.
