DETAILED DESCRIPTION

[0026] In one embodiment, as shown in Figures 1-7 A kapok petal fiber extraction process, comprising the following steps: Step one: remove the calyx, stamen and other impurities of the picked fresh kapok petals, wash them clean with clean water, then dry them by natural air drying or low-temperature drying, and then grind the dried petals into powder by a high-speed pulverizer; Step two: beat the powder by a grinder or a stone mortar to break the cell wall structure and preliminarily separate the fibers from other tissues, and then use the device body 1 to separate the fibers from other tissue impurities by airflow according to the density difference between the fibers and the impurities; Step three: wash the dust and soluble impurities in the fibers with clean water, and then dry the fibers, so that crude petal fibers can be obtained; The bottom end of the device body 1 is integrally formed with a first discharge hopper 6, the bottom end of the device body 1 is integrally formed with a second discharge hopper 8, the second discharge hopper 8 is located at one end of the first discharge hopper 6, two limiting insertion plates 10 are symmetrically arranged below the device body 1, the two limiting insertion plates 10 are respectively located below the first discharge hopper 6 and the second discharge hopper 8, the bottom end of each of the two limiting insertion plates 10 is fixedly connected with a storage bag 9, a feeding pipe 4 is installed at the top end of the device body 1, a screen cylinder 5 is arranged in the device body 1, two supporting sleeve plates 7 are symmetrically rotatably sleeved on the outer wall of the screen cylinder 5, the first discharge hopper 6 is located between the two supporting sleeve plates 7, the second discharge hopper 8 is located at one end of the supporting sleeve plate 7 away from the other supporting sleeve plate 7, and a plugging mechanism for conveniently plugging the ports of the first discharge hopper 6 and the second discharge hopper 8 is arranged on the device body 1; The plugging mechanism comprises: A support cylinder 209 is installed below the main body 1 of the equipment. The support cylinder 209 is located at the bottom of the first hopper 6 and the second hopper 8. The support cylinder 209 is fixedly connected to the first hopper 6 and the second hopper 8. A limiting groove is opened at the position where the support cylinder 209 connects with the storage bag 9 and the limiting plate 10 to allow the storage bag 9 and the limiting plate 10 to slide. A connecting roller 204 is rotatably connected inside the support cylinder 209. The connecting roller 204 is located above the two limiting plates 10. A second discharge groove 2010 is opened at the bottom of the first hopper 6 and the second hopper 8 of the support cylinder 209. A first discharge groove 208 is opened below the second discharge groove 2010 of the connecting roller 204. The first discharge groove 208 is located above the limiting plate 10. The support cylinder 209 is provided with a fixing mechanism for conveniently engaging and fixing the limiting insert plate 10; In this embodiment, it is important to note that the main body of the equipment 1 is a fine powder classification device that uses high-speed airflow as a carrier, which is different from traditional gravity screening. Its core is to achieve screening by means of the combined effect of centrifugal force, cyclone propulsion force and airflow suspension. During operation, the material is fed evenly by the spiral feed rod and premixed with the airflow to form a gas-solid two-phase flow. The high-speed rotation of the impeller drives the material to spiral forward along the screening cylinder 5 inside the main body of the equipment 1. Fine particles with a particle size smaller than the screen hole are driven by kinetic energy to pass through the screening cylinder 5 and be discharged and collected from the first discharge hopper 6. Coarse particles that do not pass through are discharged and collected from the second discharge hopper 8 along the inner wall of the screening cylinder 5. In use, impurities and fibers can be separated by screening through the screening cylinder 5, and fibers and impurities can be guided by the first discharge hopper 6 and the second discharge hopper 8 respectively. Then, through the cooperation of the second discharge trough 2010 and the first discharge trough 208, fibers and impurities can be discharged into the inner cavity of the two storage bags 9 respectively, thereby realizing the separate collection of fibers and impurities. When the storage bag 9 needs to be replaced, the sealing mechanism can simultaneously seal the ports of the two second discharge troughs 2010, effectively preventing the leakage of fibers and impurities during the process of replacing the storage bag 9. During this process, the locking mechanism can release the locking of the limit plate 10 as the connecting roller 204 rotates. Then, the storage bag 9 can be moved by pulling the limit plate 10, so as to replace the storage bag 9 without stopping the machine, thereby further improving the efficiency of fiber and impurity screening and collection. In one embodiment, such as Figures 1-7 As shown, the sealing mechanism also includes: A rotating assembly mounted on the support cylinder 209; The rotating assembly includes: A transmission turntable 202 is provided at one end of the support cylinder 209. A transmission shaft 203 is fixedly connected to one end of the transmission turntable 202. The transmission shaft 203 passes through the support cylinder 209 and is fixedly connected to the connecting roller 204. The transmission shaft 203 is rotatably connected to the support cylinder 209. A handle is installed at the end of the transmission turntable 202 away from the transmission shaft 203. The connecting roller 204 is provided with a positioning component for rotating and positioning the connecting roller 204; The transmission turntable 202 is provided with a locking component for locking and fixing the transmission turntable 202; The positioning components include: Multiple first limiting slide plates 205 are circumferentially equidistantly slidably connected inside the connecting roller 204. Each of the multiple first limiting slide plates 205 is fixedly connected to a first positioning block 207 at one end. The outer wall of the first positioning block 207 away from the first limiting slide plate 205 is hemispherical. The first positioning block 207 passes through the connecting roller 204 to the inside of the support cylinder 209. The first positioning block 207 is slidably connected to the connecting roller 204. A first spring 206 is provided at the end of the first limiting slide plate 205 away from the first positioning block 207. One end of the first spring 206 contacts the outer wall of the first limiting slide plate 205, and the other end of the first spring 206 contacts the inner wall of the connecting roller 204. Through the cooperation of the rotating component and the positioning component, the connecting roller 204 can be driven to rotate and position, thereby ensuring that the connecting roller 204 synchronously seals the ports of the two second discharge troughs 2010. In one embodiment, such as Figures 1-5 As shown, the locking assembly includes a knurled bolt 201 located at the end of the transmission turntable 202 away from the support cylinder 209. The knurled bolt 201 is located above the handle and passes through the transmission turntable 202 to the interior of the support cylinder 209. The knurled bolt 201 is threadedly connected to the support cylinder 209. The transmission turntable 202 can be locked and fixed by the knurled bolt 201, effectively preventing the transmission turntable 202 from loosening and rotating during use. In one embodiment, such as Figures 3-6 As shown, the fixing mechanism includes: A locking assembly is provided on the limit plate 10; The card-connecting components include: Two second limiting slide plates 304 are symmetrically arranged on the outside of the limiting plate 10. A second positioning block 305 is fixedly connected to one end of each second limiting slide plate 304 near the limiting plate 10. The outer wall of the second positioning block 305 away from the second limiting slide plate 304 is hemispherical and extends into the interior of the limiting plate 10. A movable slide rod 302 is fixedly connected to one end of the second limiting slide plate 304 away from the second positioning block 305. The movable slide rod 302, the second limiting slide plate 304, and the second positioning block 305 are all slidably connected to the support cylinder 209. A second spring 303 is sleeved on the outer wall of the movable slide rod 302. One end of the second spring 303 contacts the outer wall of the second limiting slide plate 304, and the other end of the second spring 303 contacts the inner wall of the support cylinder 209. The movable slide bar 302 is provided with a limiting component for limiting the movement of the movable slide bar 302; The limiting component includes a movable baffle 301 disposed at the end of the movable slide bar 302 away from the second limiting slide plate 304. The movable baffle 301 is fixedly connected to the connecting roller 204. A movable groove for sliding the movable baffle 301 is provided at the contact position between the support cylinder 209 and the movable baffle 301. Through the cooperation of the locking component and the limiting component, the purpose of convenient locking and stopping of the limiting insert plate 10 can be achieved.

[0027] The above embodiments disclose a process for extracting kapok petal fibers. In use, impurities and fibers can be separated by screening through a sieve cylinder 5, and fibers and impurities can be guided by a first discharge hopper 6 and a second discharge hopper 8 respectively. Then, through the cooperation of the second discharge trough 2010 and the first discharge trough 208, fibers and impurities can be discharged into the inner cavities of two storage bags 9 respectively, thereby achieving separate collection of fibers and impurities. When the storage bag 9 needs to be replaced, the knurled bolt 201 is rotated to separate from the support cylinder 209, thereby releasing the limit lock on the transmission turntable 202. Then, the transmission turntable 202 is rotated by the handle. At this time, the connecting roller 204 rotates under the drive of the transmission turntable 202 via the transmission shaft 203, thereby causing the ports of the first discharge chute 208 and the second discharge chute 2010 to be misaligned, so as to achieve the purpose of sealing the port of the second discharge chute 2010. At the same time, the first positioning block 207 is connected to the roller 204. Driven by the movement, the first positioning block 207, blocked by the inner wall of the support cylinder 209, pushes the first limiting slide plate 205 to slide along the inner wall of the connecting roller 204. At the same time, the first limiting slide plate 205 retracts by moving and squeezing the first spring 206. When the ports of the first discharge chute 208 and the second discharge chute 2010 are completely misaligned, the first spring 206 rebounds and pushes the first limiting slide plate 205 to insert the first positioning block 207 into the interior of the support cylinder 209, thereby achieving rotational limitation of the connecting roller 204. During this process, the movable baffle 301 slides along the inner wall of the movable slide groove under the drive of the connecting roller 204 until the movable baffle 301 contacts the inner wall of one end of the movable slide groove. This allows the movable baffle 301 and the movable slide rod 302 to be misaligned, thereby releasing the limiting obstruction on the end of the movable slide rod 302, so as to release the locking and fixing of the limiting insert plate 10. Then, the limiting plate 10 is pulled to move along the inner wall of the support cylinder 209 to the outside of the support cylinder 209. At this time, the second positioning block 305 is pushed by the limiting plate 10 and pushes the moving slide bar 302 to slide along the inner wall of the support cylinder 209 through the second limiting slide plate 304. At the same time, the second limiting slide plate 304 retracts by moving and squeezing the second spring 303. When the second positioning block 305 is completely separated from the limiting plate 10, the second spring 303 pushes the second limiting slide plate 304 by rebound to make the second positioning block 305 slide back. Then, the above operation is reversed to achieve the purpose of replacing the storage bag 9 without stopping the machine, thereby further improving the efficiency of fiber and impurity screening and collection.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
