[0031] The present invention is further described below with reference to the accompanying drawings and examples.

[0032] Example

[0033] A green onion peeling machine comprises a conveyor belt mechanism 1 and a frame 2, wherein the conveyor belt mechanism 1 is installed in the frame 2; a root cutting mechanism 3 is installed on the right side of the conveyor belt mechanism 1 along the conveying direction of the conveyor belt mechanism 1, and the root cutting mechanism 3 is used to cut the root part of the green onion; a skin breaking mechanism is installed in sequence after the root cutting mechanism 3, and the skin breaking mechanism includes a ring cutting mechanism 5 and a skin bursting mechanism 6, wherein the ring cutting mechanism 5 is used to ring cut the outer skin at the root of the green onion, and the high-pressure airflow generated by the skin bursting mechanism 6 is blown toward the ring cut at the root of the green onion to burst the onion skin; a skin blowing mechanism 7 is installed after the skin breaking mechanism, and the skin blowing mechanism 7 is installed above the conveyor belt mechanism 1, and the high-pressure airflow generated by the skin blowing mechanism 7 is used to blow the onion skin off the green onion.

[0034] The circular cutting mechanism 5 includes a pair of vertically arranged cutter discs 51, and the cutter discs 51 are divided into an upper cutter disc and a lower cutter disc. The lower cutter disc is fixedly mounted on the frame 2, and the upper cutter disc is mounted on one end of a rocker arm 52, and the other end of the rocker arm 52 is hinged to the frame 2; the middle part of the rocker arm 52 is placed on a lifting rod 53, and the lifting rod 53 is mounted on the frame 2. The swing arm 52 is set to be inclined and the end of the knife disc 51 is lower than the hinged end. Under the limiting action of the lifting rod 53, there is a gap between the upper knife disc and the lower knife disc, and the width of the gap is slightly smaller than the diameter of the green onion. The root of the green onion passes through the gap, and the two knife discs 51 cut the onion skin at the root of the green onion in a ring shape. Since the onion skin is thin, the blade of the knife disc 51 is sharp, and the thickness of the green onion may vary, the swing arm 52 of the upper knife disc is set to be hinged. The ring cutting force of the two knife discs 51 on the root of the green onion is provided by the gravity of the swing arm 52 and the upper knife disc, which can realize swing-type ring cutting, avoid cutting too deep, and ensure that green onions of different thicknesses can pass smoothly through the gap between the two knife discs 51. Moreover, in order to smoothly ring cut the onion skin, a counterweight block can be installed on the swing arm 52 to increase the cutting force.

[0035] The peeling mechanism 6 includes a pair of air nozzles 61, symmetrically mounted on the sides of a turntable 62. A motor 63 is mounted on the rotating shaft at the upper end of the turntable 62. The air nozzles 61 eject a high-speed airflow directed toward the ring-shaped cutout at the root of the scallion. The rotation of the motor 63 drives the turntable at high speed, and the high-speed rotation of the two air nozzles 61 forms an airflow column that blows toward the ring-shaped cutout at the root. The airflow enters the onion skin from the upper and lower ring-shaped cutouts, exploding and breaking the skin. Furthermore, because the onion skin is wrapped around the stalk, the high-pressure airflow easily blows the skin away from the root at the ring-shaped cutout, preventing the skin from remaining attached to the root and facilitating subsequent peeling of the skin from the scallion.

[0036] The skin-blowing mechanism 7 includes two groups of skin-blowing components 71, which are installed in sequence along the moving direction of the conveyor belt mechanism 1, with the first group of skin-blowing components 71 biased toward the leaf end of the scallion, and the second group of skin-blowing components 71 biased toward the root end of the scallion; the skin-blowing components 71 are capable of blowing out a high-pressure airflow, the direction of the high-pressure airflow being toward the conveyor belt, and the high-pressure airflow being tilted toward the root end of the scallion. After the scallion has been processed by the skin-blasting mechanism 6, the onion skin has been broken by the airflow. When it then passes through the skin-blowing mechanism 7, the airflow from the first skin-blowing component 71 first blows the onion skin from the leaf end to the root end, and then the second skin-blowing component 71 blows the onion skin at the root end directly to the right side of the conveyor belt mechanism, completely blowing the onion skin clean.

[0037] The leather blowing assembly 71 includes a mounting frame 711, a windshield 712 is installed at the lower end of the mounting frame 711, and two axially symmetrical and adjacent air ducts 713 are provided on the windshield 712. The air ducts 713 are arc-shaped, and a coaxial turntable 2 714 is provided above each of the air ducts 713. Two air nozzles 2 715 are symmetrically installed on the side of the turntable 2 714. The air nozzles 2 715 are located directly above the air duct 713. A motor 2 716 is installed above the turntable 2 714 through a pulley. The rotation of the motor 2 716 can drive the turntable The second motor 714 rotates, thereby driving the second air nozzle 715 to rotate along the air duct 713. In the same skin blowing component 71, the second air nozzles 715 in the two air ducts 713 are symmetrically arranged and rotate synchronously in opposite directions, that is, the two motors 716 rotate in opposite directions; the second air nozzles 715 are all tilted toward the front of the rotation direction; and the airflow blown by the two groups of the skin blowing components 71 to the conveyor belt mechanism 1 is biased toward the side of the root of the onion; two concentric annular protective walls are provided on the inner and outer sides of the rotation track of the second air nozzle 715, and the annular protective walls are fixedly mounted on the wind shield 712.

[0038] The root cutting mechanism 3 includes a motor 31 and a blade disc 1 32. The motor is mounted on the frame 2, and the blade disc 1 32 is mounted on the rotating shaft of the motor 31. The blade disc 1 32 includes radially mounted strip blades 33. The circular path formed by the rotation of the strip blades 33 is used to remove the roots of the green onions. The strip blades 33 are evenly distributed around the circumference of the blade disc 1 32. After the motor 3 31 is activated, the blade disc 1 32 rotates, and the strip blades 33 rotate to form a disc-shaped cutting area. The roots of the green onions moving on the conveyor mechanism are removed as they pass through the root cutting mechanism 3. In addition, a first leaf cutting mechanism 8 is mounted on the left side of the conveyor mechanism 1, opposite the root cutting mechanism 3. This first leaf cutting mechanism 8 is symmetrically arranged with the root cutting mechanism 3 and is used to remove the yellow leaves of the green onions. Moreover, a second leaf cutting mechanism 9 is installed on the left side of the skin blowing component 71 and the left side of the conveyor belt mechanism. The second leaf cutting mechanism 9 is the same as the first leaf cutting mechanism 8. After the roots of the green onions are cut off, the green onions for high-quality packaging have requirements on the length of the green onions, so the second leaf cutting mechanism 9 is used to set the length of the green onions and cut off the grown green onion leaves. At this time, the cut green onion leaves can be recycled after being cut off, and a collection box can be placed below the second leaf cutting mechanism 9 to recycle the cut leaves.

[0039] A cleaning mechanism 10 is installed before the root cutting mechanism 3. This cleaning mechanism 10 comprises a pair of air nozzles 3 101, symmetrically mounted on the sides of a turntable 3 102. The turntable 3 102 is mounted on the shaft of a motor 4 103, which is mounted on the frame 2. The airflow columns formed by the rotation of the two air nozzles 3 101 are directed toward the roots of the green onions. The cleaning mechanism 10 is designed to remove dirt and other impurities from the roots and stalks of the green onions before root cutting begins, ensuring a clean environment for subsequent green onion processing.

[0040] In addition, when the cleaning mechanism 10 blows away the impurities at the roots of the green onions, the roots of the green onions will be blown into disorder, and the roots of the green onions are dense, and the soil particles hidden therein are not easy to be blown clean, so a root combing mechanism 12 is added between the cleaning mechanism and the root cutting mechanism 3, and the root combing mechanism 12 includes a motor 5 121 and a combing assembly, the motor 5 121 is installed on the frame 2, the combing assembly includes a combing wheel 122, the combing wheel 122 is installed on the rotating shaft of the motor 5 121, and the combing wheel 122 includes several The toothed disc is mounted on an axis, and teeth are evenly distributed on the circumference of the outer circle of the toothed disc. All the toothed discs are installed at equal intervals, and coaxially arranged pads are installed between adjacent toothed discs. The diameter of the pads is smaller than the root diameter of the teeth of the toothed discs, and the pads are used to fix the spacing between adjacent toothed discs. A vertical scraper 123 is installed on one side of the combing wheel 122, and a row of comb teeth is processed on one side of the scraper 123. The comb teeth are inserted into the side surface of the combing wheel 122, and the ends of the comb teeth are pressed against the outer circumferential surface of the pad. The motor 5 121 drives the combing wheel 122 to rotate. The teeth on the combing wheel 122 scrape the roots to comb them out. At the same time, the soil particles mixed in the roots can also be combed out, so that the roots of the green onions are combed neatly and cleanly, making sufficient preparations for subsequent root cutting. In addition, the comb teeth are stuck on one side of the combing wheel 122. When the combing wheel 122 combs the roots, soil will be stuck in the gap of the combing wheel 122. The function of the comb teeth is to scrape off the stuck soil to ensure the normal function of the combing wheel 122.

[0041] The conveyor belt mechanism 1 includes a main conveyor belt 11, an auxiliary conveyor chain 12 and an auxiliary conveyor belt 13, all of which are driven synchronously and at a uniform speed. The auxiliary conveyor chain 12 is arranged parallel to the main conveyor belt 11 and is installed on the right front section of the main conveyor belt 11. The auxiliary conveyor belt 13 is installed on the right rear end of the main conveyor belt 11. The tail end of the auxiliary conveyor chain 12 is adjacent to the head end of the auxiliary conveyor belt 13; the length of the auxiliary conveyor chain 12 extends between the skin exploding mechanism 6 and the skin blowing mechanism 7. After the green onions are placed on the main conveyor belt 11, the roots are suspended in the air on the auxiliary conveyor chain 12. When passing through the cleaning mechanism 10, the root cutting mechanism 3, the ring cutting mechanism 5 and the peeling mechanism 6, it can ensure that the roots of the green onions are suspended in the air, which is convenient for blowing off the soil, cutting off the roots, ring cutting the roots and peeling the ring cuts, etc. After these processes, the roots and soil that fall off can fall smoothly and will not remain on the main conveyor belt; and when the green onions pass through the skin blowing mechanism 7, the roots of the green onions are suspended in the air and cannot achieve a good skin blowing effect, so a secondary conveyor belt 13 is set at the skin blowing mechanism 7 to connect.

[0042] The auxiliary conveyor chain 12 is provided with partitions 121 at equal intervals (the partitions are not shown in all the drawings and are only shown in the drawings). Figure 2), the spacing between the partitions 121 is 38.1 mm, and placement grooves 122 are formed between adjacent partitions 121. A lifting wheel 123 is installed on the rotating shaft at the tail end of the auxiliary conveying chain 12, and a lifting groove 124 is formed on the circumference of the lifting wheel 123. The central angle of the placement groove 122 on the rotating shaft at the tail end of the auxiliary conveying chain 12 is equal to the central angle of the lifting groove 124. When the green onions are placed, one green onion is placed in each placement slot 122, and the partition 121 plays the role of positioning and sorting the green onions to avoid the green onions from piling up on the conveyor belt during subsequent cleaning, combing, root cutting, ring cutting, peeling and other processes, which affects the effect of green onion processing; due to the partitions 121 set on the auxiliary conveyor chain 12, the green onions will pile up when they are directly transferred from between the partitions 121 to the auxiliary conveyor belt 13, and may even fall or be scratched, so a lifting wheel 123 is installed at the tail of the auxiliary conveyor chain 12. When the green onions move to this place, they can be lifted from the auxiliary conveyor chain 12 and transferred to the auxiliary conveyor belt.

[0043] A parallel aligning plate 125 is installed on the outside of the head end of the auxiliary conveyor chain 12, and the aligning plate 125 extends to the cleaning mechanism 10. The aligning plate 125 is a long strip of board. When the green onions are placed, the roots of the green onions directly touch the aligning plate 125, which is used to position the length of the green onion roots in the air and ensure the accuracy of the position during subsequent processing.

[0044] A sponge belt 111 is provided on the main conveyor belt 11, and a compression belt mechanism 14 is installed on the sponge belt 111. The belt surface of the compression belt mechanism 14 is provided with a sponge belt 2 141. The compression belt mechanism 14 moves synchronously with the main conveyor belt 11 in the same direction. A row of tensioning wheels 142 are installed inside the compression belt mechanism 14. A cross bar is provided inside the compression belt mechanism 14. The tensioning wheel 142 is installed below the cross bar and the tensioning wheel 142 is pressed on the sponge belt 2 141. A compression spring (not drawn in the accompanying drawings) is installed between the tensioning wheel 142 and the cross bar. The position where sponge belt 111 and sponge belt 2 141 are pressed together is the position of the onion leaves, which is used to press the onion leaf part of the onion and convey it synchronously on the main conveyor belt 11 to prevent the onions from piling up or falling in various processing steps. Combined with the placement groove 122 on the auxiliary conveyor chain 12, the leaf part and the onion part of the onion can be positioned synchronously. In the skin blowing process, since the root position of the onion is the auxiliary conveyor belt 13, the clamping belt mechanism 14 plays a major positioning role at this time, preventing the onion from being blown crooked or blown off the conveyor belt when the skin blowing mechanism 7 is tilted to blow the skin.

[0045] When the green onion peeling machine of the embodiment of the present invention is used, green onions are manually placed on the conveyor mechanism 1, and the green onions are placed in the placement groove 122 of the auxiliary conveyor chain 12 at one time, and the roots are aligned on the straightening plate 125. As the conveyor mechanism 1 moves, the following processing steps are performed in sequence: (1) the first step is that the cleaning mechanism 10 cleans the dirt at the roots and the root rods, and the blown-off dirt and impurities fall from the auxiliary conveyor chain 12; (2) the second step is that the combing mechanism 12 combs the roots of the green onions and scrapes off the mud and sand hidden in the roots; 3) The third process is that the root cutting mechanism 3 cuts off the roots of the green onions, and the cut roots fall from the auxiliary conveyor chain 12. At the same time, the first leaf cutting mechanism 8 cuts off the yellow leaves at the ends of the green onions. (4) The fourth process is that the ring cutting mechanism 5 cuts the roots of the green onions in a ring-shaped incision, and after the ring cutting, the skin-breaking mechanism 6 breaks the onion skin from the ring-shaped incision. (5) The fifth process is that the skin-blowing mechanism 7 blows off the broken onion skin, completely removing the onion skin from the green onions. At the same time, the second leaf cutting mechanism 9 can cut the peeled green onions into a fixed length, processing them into high-quality green onions of the required length. After the above five processes, the roots and skins of the green onions are completely removed.
