Description

Technical Field

[0001] This invention relates to the field of corn silk separation technology, and more particularly to a corn silk separation device for extracting polysaccharides from corn silk. Background Technology

[0002] Corn silk polysaccharide is a natural active ingredient extracted from corn silk. It has a variety of biological activities and potential application value. In addition, its good water solubility and biocompatibility make it a potential product for development in functional foods, pharmaceutical excipients and cosmetics. It is a hot topic of interest in natural product research and the health industry. To extract polysaccharide from corn silk, a corn silk separation device is needed to separate the corn silk from the corn fruit.

[0003] For example, Chinese Patent No. CN215774321U discloses a corn silk separation device, which relates to the field of corn processing technology, including: a body; an inclined plate, the inclined plate being located on the inner wall of the body; and a conveyor belt, the conveyor belt being disposed on the inner wall of the body and located on one side of the inclined plate.

[0004] The aforementioned device achieves the function of scraping corn silk adhering to the outer wall of corn by setting a rotating mechanism. However, in use, the corn skin needs to be removed before scraping, which requires manual peeling, resulting in low separation efficiency of corn silk. In addition, the polysaccharide content of corn silk at the end and base of the corn is different. Extracting the corn silk at the end with higher polysaccharide content separately can reduce the impurity load and lower the purification cost. The existing device is not convenient for classifying and collecting corn silk from different parts, resulting in high subsequent purification costs. Summary of the Invention

[0017] Compared with existing technologies, the advantages of this invention are:

[0018] 1. The present invention, by setting up a conveying component, a limiting component, a head and tail removal component and a peeling component, twists the corn silk into a bundle before removing the head and tail. This can avoid the situation where the corn silk is scattered and difficult to collect after being cut. At the same time, by limiting the fixed arc strip and the moving arc strip, the airflow blown out of the air outlet pipe will not blow the corn silk away, which can effectively reduce the omission during corn silk collection and improve the collection integrity.

[0019] 2. By setting up a conveying component, a limiting component, a peeling component, and a peeling component, this invention can remove most of the corn husks in advance by using a gas peeling followed by a brush peeling method, which reduces the difficulty of subsequent separation and also reduces the brushing time, thus reducing the damage to the corn kernels.

[0020] 3. This invention classifies and collects corn silk from the ends and base of corn with different polysaccharide contents, which facilitates the separate extraction of corn silk from different locations, reduces impurity load, and lowers the purification cost of polysaccharide extraction.

[0039] The rotating component 33 includes a first arc strip 331 fixedly connected to one end of the first electric telescopic rod 32. A second arc strip 332 is slidably connected to the inner side of the first arc strip 331. An external toothed ring 333 is fixedly connected to one side of the second arc strip 332 and meshes with the rack 27. The sum of the number of teeth of the rack 27 and the toothed plate 28 is twice the number of teeth of the external toothed ring 333. When the external toothed ring 333 moves to the side of the clamping moving component 62, the external toothed ring 333 rotates one and a half times. Then, the external toothed ring 333 continues to move, which can make the external toothed ring 333 rotate two times.

[0040] A fixed arc strip 334 is fixedly connected to the inner side of the first arc strip 331. A fitting groove 335 is provided at the contact position between the inner side of the first arc strip 331 and the second arc strip 332.

[0042] The peeling assembly 8 includes an adjustment section 81 located at the lower end of the linear slide 7. A first clamping plate 82 and a second clamping plate 83 are spaced apart at the lower end of the adjustment section 81. The second clamping plate 83 has a cavity inside.

An air pump 84 is fixedly connected to the inner wall of one side of the outer casing 1, and the air outlet of the air pump 84 is connected to the cavity inside the second clamping plate 83 through a hose. The height of the first clamping plate 82 and the second clamping plate 83 and the distance between the first clamping plate 82 and the second clamping plate 83 can be adjusted by the adjustment section 81. This is a known prior art, and those skilled in the art can conceive of the specific structure. When air is blown into the cavity inside the second clamping plate 83 by the air pump 84, the air can be ejected through the multiple sets of air outlets 87.

The output end of the third motor 86 is fixedly connected to the adjacent set of rotating disks 85. When the first clamping plate 82 and the second clamping plate 83 are close together, the multiple sets of fixing pins will be embedded in the corn cob, thereby fixing the corn. The third motor 86 can make both sets of rotating disks 85 and the corn rotate.

[0044] The head and tail removal assembly 6 includes a mounting plate 61 fixedly disposed between the inner walls on both sides of the outer casing 1. The lower end of the mounting plate 61 is provided with a clamping and moving part 62 and a cutting part 63 spaced apart, and the clamping and moving part 62 and the cutting part 63 are disposed on the same vertical plane. The cutting part 63 includes an electric telescopic rod, a position adjustment part and a blade. Cutting off the head and tail of the corn by the cutting part 63 is a known prior art, and those skilled in the art are able to conceive of the specific structure.

[0045] The clamping and moving component 62 includes a fourth motor 621 fixedly connected to the lower end of the mounting plate 61. A connecting plate 622 is fixedly connected to the lower end of the fourth motor 621. Two sets of second electric telescopic rods 623 are spaced apart at the lower end of the connecting plate 622. Each set of second electric telescopic rods 623 has a clamping part 624 at its lower end. One set of clamping parts 624 is located above the toothed plate 28. The height of the clamping parts 624 can be adjusted by the two sets of second electric telescopic rods 623. The two sets of clamping parts 624 can be rotated by the fourth motor 621.

[0046] The peeling assembly 5 includes a fourth conveyor 51 fixedly installed inside the U-shaped plate 21. A first motor 52 and a second motor 54 are fixedly connected at intervals on one side of the U-shaped plate 21. The output end of the first motor 52 passes through the U-shaped plate 21 and is fixedly connected to a brush roller 53. The output end of the second motor 54 passes through the U-shaped plate 21 and is fixedly connected to a first comb plate 55. Both the brush roller 53 and the first comb plate 55 are located above the fourth conveyor 51. One end of the first comb plate 55 is rotatably connected to the L-shaped baffle 26 through a connecting block. The first motor 52 and the second motor 54 are used to drive the brush roller 53 and the first comb plate 55 to rotate, respectively.

[0047] In this invention, the second conveyor 23 rotates clockwise. When the second conveyor 23 pauses, an external robotic arm places corn kernels with husks onto the placement strip 31, ensuring that the exposed corn silks are inside the second arc strip 332 and in contact with the moving arc strip 354. Simultaneously, the corn silks embed into the gaps of the second toothed plate 34. The second conveyor 23 then transports the placement strip 31 and the corn kernels. When the placement strip 31 moves to one side of the end of the toothed rack 27, the outer toothed ring 333 engages with the toothed rack 27. As the second conveyor 23 continues to transport, the outer toothed ring 333 rolls on the toothed rack 27, causing the spring buckle 336 to retract into the second arc strip 332 and separate from the engagement groove 335, until the outer toothed ring 333... When the outer toothed ring 333 moves below the clamping moving part 62, it rotates one and a half times. During this process, the second arc strip 332 and the moving arc strip 354 rotate together with the outer toothed ring 333. Under the elastic force of the two sets of pressure springs 352, the moving arc strip 354 can twist and clamp the corn silk inside the second arc strip 332 between the moving arc strip 354 and the fixed arc strip 334 during rotation. The second toothed plate 34 can prevent the corn with skin from being pulled excessively when the corn silk is twisted and fixed, thereby avoiding the situation of cutting misalignment. The setting of the limiting component 3 can achieve the purpose of twisting clamping and corn limiting while conveying, without the need for multiple drive structures, which is convenient to use. After the outer toothed ring 333 moves below the clamping moving part 62, the head and tail of the corn with husks are cut off by the cutting part 63. Then, the outer toothed ring 333 slides on the toothed plate 28 by the first electric telescopic rod 32, widening the gap between the second toothed plate 34 and the placement strip 31. Then, the clamping part 624 moves downward by the second electric telescopic rod 623, clamping and fixing the twisted bundle of corn silk from the middle. Then, the corn silk and the cut-off corn ends are clamped and lifted. The clamping part 624 vibrates up and down continuously by the second electric telescopic rod 623, which can vibrate and separate the corn silk from the corn end fragments. The fallen fragments and the remaining cut-off parts are carried away by the vibration. The corn silk is conveyed by the second conveyor 23 and falls onto the third conveyor 24. The counterclockwise rotation of the third conveyor 24 can transport the fragments to the outside of the outer box 1. Then, the fourth motor 621 causes the two sets of clamping parts 624 to interchange positions. The corn silk is then placed on the first conveyor 4, which can collect the end corn silk and transport it to the required position. By twisting the corn silk into a bundle before removing the head and tail, this invention can avoid the situation where the corn silk is scattered and difficult to collect after being cut. At the same time, by limiting the fixed arc strip 334 and the movable arc strip 354, the airflow blown out by the air outlet 25 will not blow the corn silk away, which can effectively reduce the leakage during corn silk collection and improve the collection integrity.

[0048] After removing the heads and tails of the corn with husks, the second conveyor 23 continues to transport the corn. After the outer toothed ring 333 separates from the toothed plate 28, the outer toothed ring 333 rotates a full two revolutions. At this time, the four sets of spring buckles 336 are respectively embedded in the four sets of fitting grooves 335, which can fix the opening of the second arc strip 332 upwards inside the first arc strip 331, facilitating subsequent recycling. The corn is then transported by the second conveyor 23 to below the husk removal assembly 8. At this time, the first clamping plate 82 and the second clamping plate 83 are located at both ends of the corn. The adjusting part 81 brings the first clamping plate 82 and the second clamping plate 83 closer together, so that multiple sets of fixing pins are embedded in the corn cob. Then, the corn is transported by a linear slide table. The 7th and 81 adjustment units move the corn to a position 10 cm above the third conveyor 24. High-pressure airflow is blown out from multiple air outlets 87 by the air pump 84. Because the corn tail is cut off, the airflow can enter through the gaps in the corn husk, quickly blowing away most of the husk. The L-shaped baffle 26 and U-shaped plate 21 prevent the husk from scattering. The corn is then moved between the brush roller 53 and the first comb plate 55, bringing the corn into contact with the brush roller 53. The rotation of the brush roller 53 removes any remaining husk and silk at the contact point. The third motor 86 drives the corn to rotate, removing the outer layer of corn silk. The corn and residual corn husks are brushed off onto the fourth conveyor 51. The corn is then placed on the fourth conveyor 51 for transport. The peeling assembly 8 then resets to process the remaining corn. During this process, the second motor 54 causes the first comb plate 55 to embed inside the brush roller 53, transferring the corn silk from the brush roller 53 to the first comb plate 55. The first comb plate 55 then rotates clockwise, separating the corn silk from the brush roller 53 and causing it to fall onto the fourth conveyor 51. The fourth conveyor 51 transports the corn, a small amount of residual corn husks, and corn silk to the external separation structure, where they are peeled off by first gas peeling followed by brushing. This method can remove most of the corn husk in advance, reducing the difficulty of subsequent separation. It can also reduce brushing time, reduce damage to the corn kernels, and improve processing results. This invention can realize the automated separation of corn silk without the need for manual removal of corn husk, thus improving the separation efficiency of corn silk. It can also classify and collect corn silk from the ends and base of the corn with different polysaccharide contents, which is convenient for subsequent extraction of corn silk from different locations. This can reduce the impurity load and lower the purification cost of polysaccharide extraction. At the same time, in the process of collecting the end corn silk, the corn silk is twisted into a bundle before the head and tail are removed, which improves the integrity of the corn silk collection.
