[0043] Please also read Figures 1 to 12 , the fresh corn layer-retaining processing equipment and the layer-retaining processing method provided by the present invention are now described. The fresh corn layer-retaining processing equipment comprises a feeding reversing unit, a head and tail cutting unit 3, a peeling unit 4, a detection unit 5 and a packing unit 6 arranged in sequence, the feeding reversing unit comprises a lifting component 1 and a reversing component 2 connected to the discharge end of the lifting component 1, the head and tail cutting unit 3 comprises a conveying frame 31, a conveying chain 32 connected to the conveying frame 31 to convey corn cobs, and a head cutting saw disk 33 and a tail cutting saw disk 34 respectively connected to the conveying frame 31 in rotation, the peeling unit 4 comprises a supporting frame 41 and two peeling rollers 42 respectively connected to the supporting frame 41 in rotation and extending downwardly in an inclined manner, the two peeling rollers 42 can rotate in opposite directions to remove the outer husks on the corn cobs, the detection unit 5 comprises an image collector 51 for collecting first image information of the corn cobs and a controller electrically connected to the image collector 51, and the controller is used to receive the first image information sent by the image collector 51.

[0044] Compared with the prior art, the fresh corn layer retention processing equipment provided in this embodiment can perform directional adjustment on the fresh corn, and remove the head and tail of the corn cob by reasonable positioning, so as to achieve the effect of removing the outer bracts of the corn cob and simultaneously retaining 2-4 layers of inner bracts, thereby achieving reasonable layer retention of bracts, ensuring the processing quality of fresh corn, realizing effective detection of fresh corn, reducing labor consumption, and improving the processing efficiency of fresh corn. The above-mentioned equipment can reasonably design multiple working steps such as loading, reversing, cutting heads and tails, peeling and packing, realize the optimized layout of the production line, and ensure the reliable operation of the production line.

[0045] In this embodiment, the feeding reversing unit can feed individual corn ears one by one, and perform reversing processing on corn ears with wrong direction settings, so as to ensure that the corn ears are arranged in a forward direction with consistent head and tail. The head and tail cutting unit 3 can accurately cut the corn ears through the head cutting saw disk 33 and the tail cutting saw disk 34 respectively, and then the peeling unit 4 removes the bracts without ear stalk adhesion on the outside of the corn ear with the help of the peeling roller 42, so that the outer bracts of the corn ear can be effectively removed, while ensuring that the 2-4 layers of inner bracts are retained, so as to ensure the freshness of the corn ear. After that, the detection unit 5 detects the wormholes, damage and other quality conditions of the corn ears, removes unqualified corn ears, and finally the packing unit 6 packs the qualified corn ears. The above equipment can reasonably design the layout of the production line, optimize the site area, and coordinate the production of each station to ensure reliable operation of the production line.

[0046] In a possible implementation, the lifting assembly 1 includes an upper hopper 11 and a plurality of step material plates 12 respectively arranged in the upper hopper 11. From the feed end of the upper hopper 11 to the discharge end of the upper hopper 11, the plurality of step material plates 12 are arranged in a stepped shape from low to high. A lifting plate 13 for lifting corn ears upward is provided between two adjacent step material plates 12. The tops of the step material plates 12 and the lifting plates 13 respectively have supporting surfaces 14 for supporting corn ears. A lifting assembly 18 is connected below the lifting plate 13. The two adjacent lifting plates 13 are connected by a connecting frame 15. The lower part of the step material plate 12 is provided with a sliding rod 16 that penetrates the connecting frame 15 and slides with the connecting frame 15. The lower end of the sliding rod 16 is connected to the inner wall of the upper hopper 11 through a mounting plate 17.

[0047] In this embodiment, the corn cobs need to be oriented and sorted before the head and tail are cut off, so that the corn cobs can maintain the same direction before entering the head and tail cutting process. The step plate 12 is fixedly connected to the inner wall of the upper hopper 11, and can receive the corn cobs lifted up by the lifting plate 13. The width of the step plate 12 and the lifting plate 13 is adapted to the diameter of the corn cobs, and only one corn cob can be lifted at a time. After the lifting plate 13 lifts the corn cob to the step plate 12 adjacent to it and higher than it, the lifting plate 13 located on the other side of the step plate 12 receives the corn cob and sends it to a higher step plate 12, so that a single corn cob is transported to a higher place layer by layer.

[0048] Specifically, the connecting frame 15 includes a horizontal plate 151 and a column 152 connected to the top of the horizontal plate 151. The sliding rod 16 at the bottom of the step plate 12 penetrates the horizontal plate 151 of the connecting frame 15 and forms a sliding fit with the horizontal plate 151. The horizontal plate 151 can be guided and limited to ensure the accuracy of the lifting direction of the lifting plate 13. The upper ends of the step plate 12 and the lifting plate 13 are respectively inclined toward the side close to the reversing assembly 2, and the side of the supporting surface 14 close to the reversing assembly 2 is inclined downward, so that an approximately V-shaped space that can limit the corn ears is formed between the supporting surface 14 and the side wall of the step plate 12 or the lifting plate 13 of the higher layer, so as to avoid the horizontal rolling of the corn ears and ensure the orderly supply of the corn ears to the reversing assembly 2.

[0049] Considering the overall feeding efficiency and lifting height, the structure of combining multiple step material plates 12 and multiple lifting plates 13 is more stable. Specifically, the structure of combining four lifting plates 13 with five step material plates 12 ensures the continuity and stability of the lifting process.

[0050] Furthermore, the lifting assembly 1 can disperse the corn ears stacked in the silo and form a single conveying mode, so as to ensure the subsequent accurate positioning and cutting. The lifting assembly 1 includes a crank 181 arranged below the upper hopper 11 to rotate a connecting rod 182 connected to the crank 181, and a connecting frame 15 is provided with an avoidance groove 186 for the upper end of the connecting rod 182 to pass through. The upper end of the connecting rod 182 is rotatably connected to the connecting frame 15 through a rotating shaft 184. Under the rotation drive of the drive, the connecting rod 182 can swing vertically to drive the connecting frame 15 and the lifting plate 13 to move up and down.

[0051] Specifically, a matching block 183 is connected below the transverse plate 151, and upper and lower corresponding half grooves 185 are provided on the bottom surface of the transverse plate 151 and the top surface of the matching block 183. The two half grooves 185 form a rotating groove for accommodating the rotating shaft 184. The rotating shaft 184 is rotatably connected in the rotating groove to ensure the effective driving of the connecting frame 15, thereby enabling the connecting frame 15 to drive the lifting plate 13 to move up and down.

[0052] The lifting assembly 1 adopts a crank 181 and a connecting rod 182 structure, and utilizes the rotation of the crank 181 to drive the connecting rod 182 to move, thereby realizing the effective driving of the up and down movement of the connecting frame 15, so that the lifting plate 13 installed on the connecting frame 15 produces a reciprocating movement of lifting upward and falling downward, thereby ensuring the orderly lifting of the corn cobs and improving the continuity of the corn cob feeding.

[0053] In one possible implementation, see Figures 1 to 12The reversing component 2 includes a conveyor belt 21, an industrial camera 22 arranged above the conveyor belt 21, and a reversing gripper 23 for rotating or transferring corn ears. The reversing gripper 23 can also perform reversal and rotation synchronously. The industrial camera 22 is electrically connected to the controller. The industrial camera 22 is used to obtain the second image information of the corn ears and send the second image information to the controller. The reversing gripper 23 is electrically connected to the controller. The reversing gripper 23 can receive the rotation command of the controller and reversing or transferring the corn ears, or synchronously reversing and transferring the corn ears.

[0054] In this embodiment, the reversing gripper is mainly used to convert the head and tail direction of the corn cob. The reversing component 2 obtains the second image information of the corn cob through the industrial camera 22 and sends the second image information to the controller for the controller to determine whether the direction of the corn cob is accurate. If the direction is accurate, the reversing gripper 23 is directly used to translate the corn cob to the head and tail cutting unit 3. If the direction is inaccurate, the reversing gripper 23 is used to synchronously reverse the corn cob and translate it to the head and tail cutting unit 3.

[0055] The reversing gripper 23 includes a clamping cylinder and a clamping plate connected to the output end of the clamping cylinder. The reversing gripper 23 is horizontally driven by a linear module to ensure that the corn ears can be smoothly transferred to the head and tail cutting unit 3.

[0056] On this basis, a robot capable of pushing corn ears horizontally can be arranged on the side of the conveyor belt 21. The industrial camera 22 can detect the size of the corn ears in addition to detecting the direction of the head and tail of the corn ears. If the size is unqualified, the controller sends a signal to the robot, and the robot pushes the corn ears to fall and removes the unqualified corn ears. If the size of the corn ears is qualified, the corn is rotated and reversed by the reversing clamp and translated to the head and tail cutting unit 3.

[0057] In one possible implementation, see Figures 1 to 12 The surface of the conveyor chain 32 is provided with a limiting groove 321 which is perpendicular to the conveying direction of the conveyor chain 32 and is used to accommodate corn ears. The head cutting saw disk 33 is rotatably connected to the middle part of the conveyor chain 32 and is arranged close to one side of the conveyor chain 32. The tail cutting saw disk 34 is rotatably connected to the discharge end of the conveyor chain 32 and is arranged close to the other side of the conveyor chain 32. The conveyor frame 31 is also rotatably connected with a head cutting push brush roller 35 and a tail cutting push brush roller 36 extending along the conveying direction of the conveyor chain 32. The head cutting push brush roller 35 and the tail cutting push brush roller 36 have opposite rotation directions. The head cutting push brush roller 35 is used to push corn ears to one side of the conveyor chain 32 for cutting by the head cutting saw disk 33, and the tail cutting push brush roller 36 is used to push corn ears to one side of the conveyor chain 32 for cutting by the tail cutting saw disk 34.

[0058] In this embodiment, the corn cobs are carried and limited by the limiting grooves 321 of the conveyor chain 32. Each limiting groove 321 can carry at most one corn cob, ensuring the coordinated and orderly processing. The head-cutting pushing brush roller 35 and the tail-cutting pushing brush roller 36 are used to push the corn cobs axially. Corresponding components that can limit the axial position of the corn cobs can be respectively provided on both sides of the conveyor chain 32 to ensure the accuracy of the head-cutting and tail-removing positions of the corn cobs. The head-cutting saw disk 33 is rotatably connected to the middle part of the conveyor chain 32, and the tail-cutting saw disk 34 is rotatably connected to the discharge end of the conveyor chain 32. The corn cobs first undergo the head-cutting process and then the tail is removed.

[0059] For some examples, see Figures 1 to 12 The conveying frame 31 is provided with a head limiting component 7 for limiting the head of the corn ear and a tail positioning component 8 for limiting the tail of the corn ear;

[0060] The head limit assembly 7 is arranged on one side of the head cutting saw disc 33 close to the head cutting push brush roller 35. The head limit assembly 7 includes an upper limit bar 71 and a lower limit bar 72 which are arranged at intervals in the up-down direction and extend along the conveying direction of the conveyor chain 32. A limit gap extending horizontally is formed between the upper limit bar 71 and the lower limit bar 72 for the corn ear to move horizontally toward one side of the head cutting saw disc 33.

[0061] The tail positioning assembly 8 is arranged on one side of the tail cutting saw disk 34 close to the tail cutting push brush roller 36, and the head limiting assembly 7 includes an upper positioning bar 81 and a lower positioning bar 82 which are arranged at intervals in the up and down directions and extend along the conveying direction of the conveyor chain 32, and a horizontally extending positioning gap is formed between the upper positioning bar 81 and the lower positioning bar 82 for the corn ear to move horizontally toward the side of the tail cutting saw disk 34.

[0062] In the present embodiment, during the process of removing the head and tail of a corn cob, since the head and tail of the corn cob have different shapes, there are certain differences in the structures for positioning the two, and a head limiting component 7 and a tail positioning component 8 are respectively provided.

[0063] In order to ensure that the corn cob can retain a certain number of bracts after peeling, there are certain requirements for the corn cob during the tail removal process. The bracts to be removed and the bracts to be retained need to be distinguished by different adhesion forces. The 2-4 bracts growing on each stalk of the stalk are the main source of adhesion. After the corn cob enters the limiting groove 321, the limiting groove 321 carries the corn cob to move horizontally, and first the filament part (head) of the corn cob is sent to the positioning component through the head cutting and pushing brush roller 35 to complete the quantitative cutting of the corn cob head.

[0064] The cutting head pushing brush roller 35 sends the stalk part of the corn ear to the positioning component. This positioning component can be determined according to the external morphological data of the processed corn ear. The corn can be positioned to form a reasonable cutting area. The stalk (tail) of the corn ear cut in this area, the stalk growing on the outer bracts is cut by the tail cutting disk saw, and the stalk growing on the inner bracts is retained, forming a difference in adhesion between the inner and outer bracts.

[0065] After positioning tests, the positioning component can accurately position the cutting position of the stalk of the corn ear. The positioning component consists of an upper positioning bar 81 and a lower positioning bar 82. The positioning gap in the middle allows the stalk to extend without being affected by the length of the stalk.

[0066] Specifically, from the central axis of the conveyor chain 32 to the outer side of the conveyor chain 32, the bottom surface of the upper positioning bar 81 gradually tilts outward and upward, and the top surface of the lower positioning bar 82 gradually tilts outward and downward, and a positioning gap is formed between the upper positioning bar 81 and the lower positioning bar 82 to contact the side of the corn ear close to the ear stalk to locate the axial position of the corn ear.

[0067] In one possible implementation, see Figures 1 to 12 The conveyor frame 31 is also rotatably connected to two clamping wheels 37, which are used to elastically press down the middle of the corn cob to cooperate with the head cutting saw disk 33 or the tail cutting saw disk 34 to cut the head or tail of the corn cob. In this embodiment, the two clamping wheels 37 are respectively coaxially arranged with the head cutting saw disk 33 and the tail cutting saw disk 34 and correspond horizontally, and the clamping wheels 37 can ensure stability and reliability when cutting the head and tail of the corn cob.

[0068] In one possible implementation, see Figures 1 to 12 The support frame 41 is also provided with an angle adjustment component 9 for adjusting the inclination angle of the peeling roller 42. The angle adjustment component 9 includes two supporting vertical plates 91 and two locking pieces 92. A mounting seat 93 is provided below the feed end of the peeling roller 42, and the discharge end is rotatably connected to the support frame 41. An arc-shaped extension and an adjustment groove for installing the mounting seat 93 are provided on the supporting vertical plate 91. The locking piece 92 passes through the adjustment groove and is connected to the mounting seat 93. The feed end of the peeling roller 42 is rotatably connected to the mounting seat 93. The mounting seat 93 is provided with a rotating drive member 94 for driving the peeling roller 42 to rotate.

[0069] In this embodiment, the rotary drive member 94 and the peeling roller 42 can be installed between the two supporting uprights 91 through the mounting seat 93, and the mounting seat 93 is fixed at a suitable position of the inclined upright by the locking member 92. According to the actual situation of the corn cobs to be peeled and transported, the locking member 92 is selected to be set at the corresponding position of the arc groove, and the inclination angle of the peeling roller 42 is effectively locked by the threaded connection with the mounting seat.

[0070] In addition, by changing the inclination angle of the peeling roller 42, the stress-bearing time of the corn cob on the peeling roller 42 can be adjusted, thereby reducing the damage to the inner bracts and increasing work efficiency. The above-mentioned equipment is easy to adjust the angle of the peeling roller 42. After the corn cob has been processed by head and tail removal in the previous step, the corn cob bracts now have two forms, one is the outer bract without the stalk attached, and the other is the inner bract with adhesion that needs to be retained. The processing task to be completed by the peeling unit 4 is to peel off the outer bracts, retain the inner bracts and not damage the cob. When the peeling unit 4 is running, the peeling roller 42 has a certain inclination. When the corn cob enters the peeling unit 4, the stalk tilts downward, and the peeling roller 42 rubs against the bracts of the corn cob, and then tears the outer bracts loose and falls off.

[0071] Specifically, the outer circumference of the peeling roller 42 is provided with an outer rubber sleeve, and the outer rubber sleeve is provided with a guide pattern arranged at an angle to its axis. The separate design can ensure the convenience of replacing the outer rubber sleeve, while saving the replacement cost of the outer rubber sleeve due to wear. In addition, by changing the pattern of the outer rubber sleeve, the force between the husk and the peeling roller 42 can be adjusted, reducing the difficulty of shedding the outer husk of the corn ear.

[0072] On the basis of the above structure, an arc-shaped pressure cover 44 is provided above the two peeling rollers 42, and two adjustment vertical plates 45 are provided on both sides of the support frame 41. The adjustment vertical plates 45 are provided with a slide groove extending in the up-down direction. The two sides of the arc-shaped pressure cover 44 are connected with screws extending outward and slidably connected in the slide groove, and the screws are locked with the adjustment vertical plates 45 through nuts. The two adjustment vertical plates 45 located on the same side of the arc-shaped pressure cover 44 are respectively arranged near the two ends of the arc-shaped pressure cover 44. The above structure is set so that the arc-shaped pressure cover 44 can be adjusted in the vertical direction. By adjusting the distance between the arc-shaped pressure cover 44 and the peeling roller 42, and combining with adjusting the angle of the peeling roller 42, the removal force of the peeling roller 42 on the bracts can be adjusted. At the same time, the difference in the adhesion of the inner and outer layers of the bracts after the corn cob is processed by the head and tail removal unit 3 is used to achieve the purpose of removing the outer layer of bracts and reasonably retaining the inner 2-4 layers of bracts.

[0073] For some examples, see Figures 1 to 12 A detection frame 52 is arranged above the peeling roller 42, and an image collector 51 is arranged on the detection frame 52. The image collector 51 is used to obtain the first image parameter of the corn cob after peeling and send the first image parameter to the controller. A feeding guide plate 53 extending obliquely outward and downward is provided at the discharge end of the peeling roller 42. A pushing cylinder 54 electrically connected to the controller is provided on the side of the feeding guide plate 53. The main axis of the pushing cylinder 54 is arranged perpendicular to the inclination direction of the feeding guide plate 53, and is used to receive the pushing instruction of the controller and push unqualified corn cobs to the outside of the feeding guide plate 53.

[0074] In this embodiment, the image collector 51 is a camera or other structure capable of acquiring the first image information of the corn cob. The corn cob rotates automatically under the action of the peeling roller 42, and slides downward along the peeling roller 42 under the action of gravity. During this process, the image collector 51 performs full-angle quality inspection on the corn cob with husk removed. Unqualified corn cobs include corn cobs with completely removed husks, damaged kernels, and wormholes.

[0075] In this embodiment, the feeding guide plate 53 is used to transport qualified corn ears to the packing unit 6. When the controller determines that the quality of the corn ears is qualified, the pushing cylinder 54 does not operate, and the corn ears directly slide into the packaging box 62; if the quality inspection of the corn ears fails, the pushing cylinder 54 moves to push the unqualified corn ears out, thereby preventing the unqualified corn ears from entering the packaging box 62.

[0076] Furthermore, a guide cylinder 43 may be provided at the output end of the push cylinder 54, and the guide cylinder 43 extends and penetrates along the inclined direction of the feeding guide plate 53, so that corn ears can pass through and smoothly enter the packaging box 62 below. When the corn ears are unqualified, the push cylinder 54 pushes the guide cylinder 43 to drive the corn ears to move horizontally to the outside of the packaging box 62, so as to prevent the corn ears from being loaded into the packaging box 62.

[0077] In one possible implementation, see Figures 1 to 12 The packing unit 6 includes a conveyor belt 61 arranged below the discharge end of the peeling roller 42. The conveyor belt 61 is used to support the packaging box 62 to receive the corn ears falling into the packaging box 62. The conveyor belt 61 can drive the packaging box 62 to move forward and backward to coordinate the arrangement of the corn ears into the packaging box 62 one by one.

[0078] In this embodiment, two or more layers of corn can be placed in the packaging box 62 of the packing unit 6. The conveyor belt 61 is controlled by a stepper motor. After a corn cob slides in, the conveyor belt 61 drives the carton to move forward or backward to ensure that the corn cobs fall evenly into the appropriate positions in the packaging box 62. After the packing of the lower layer of corn cobs is completed, the packing of the upper layer of corn cobs is carried out, and finally the entire packaging box 62 is packed.

[0079] Based on the same inventive concept, the embodiment of the present application also provides a method for processing fresh corn with retained layers, which uses fresh corn with retained layers processing equipment to process corn ears, including the following steps:

[0080] S100: placing corn ears into the upper hopper 11, and lifting the corn ears upwards with the lifting plate 13, so that the corn ears are sequentially conveyed upwards along a plurality of step material plates 12 to the conveyor belt 21;

[0081] S200: The industrial camera 22 identifies the placement direction of the corn ear. If the placement direction of the corn ear is the same as the preset direction, the reversing seat drives the corn ear to move onto the conveying chain 32; if the placement direction of the corn ear is opposite to the preset direction, the reversing seat drives the corn ear to rotate in the opposite direction and move it onto the conveying chain 32;

[0082] S300: The conveying chain 32 drives the corn ear to move toward the side of the head cutting saw disk 33, and the head cutting push brush roller 35 rotates circumferentially to drive the corn ear to move along its axial direction and abut against the head limiting component 7. The corn ear moves forward driven by the conveying chain 32, and the pressing wheel 37 presses the corn ear to cooperate with the head cutting saw disk 33 to cut the head of the corn ear;

[0083] S400: The conveying chain 32 drives the corn ear to move toward one side of the tail cutting saw disk 34, and the tail cutting push brush roller 36 rotates axially to drive the corn ear to move along its axial direction to abut against the tail positioning component 8. The corn ear moves forward driven by the conveying chain 32, and another clamping wheel 37 clamps the corn ear to cooperate with the tail cutting saw disk 34 to cut the tail of the corn ear;

[0084] S500: using the angle adjustment component 9 to adjust the inclination angle of the peeling roller 42, the two peeling rollers 42 rotate towards each other to peel off the outer husks on the surface of the corn ear, and the image collector 51 collects the first image information of the corn ear and sends it to the controller;

[0085] S600: When the controller determines that the corn ear is defective according to the first image information, the controller sends a pushing instruction to the pushing cylinder 54, and the pushing cylinder 54 pushes the unqualified corn ear to the outside of the feeding guide plate 53, and the qualified corn ear is sent downward along the feeding guide plate 53 into the packaging box 62;

[0086] S700: The conveyor belt 61 drives the packaging box 62 to move horizontally so that the corn ears are placed one by one or arranged in layers in the packaging box 62.

[0087] The step plate 12 and the lifting plate 13 are both inclined from bottom to top toward the side close to the discharge end of the upper hopper 11, and the side of the supporting surface 14 close to the discharge end of the upper hopper 11 gradually extends downward. Compared with the prior art, the fresh corn layer retention processing method provided in this embodiment can directional adjust the fresh corn, remove the head and tail of the corn cob by reasonable positioning, achieve the effect of removing the outer layer of the corn cob and simultaneously retaining 2-4 layers of the inner layer of the bract, achieve reasonable layer retention of the bract, ensure the processing quality of the fresh corn, achieve effective detection of the fresh corn, reduce labor consumption, improve the processing efficiency of the fresh corn, achieve the optimized layout of the production line, and ensure the reliable operation of the production line.

[0088] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
