Description

Technical Field

[0001] This invention relates to the field of fresh corn processing, and in particular to a rotary fresh corn peeling machine. Background Technology

[0002] In the fresh corn processing industry, corn husking is a crucial preliminary step for subsequent processing (such as refrigeration and deep processing into corn products), and its processing efficiency and quality directly affect the overall production pace and product quality of the industry. Currently, there are two main methods for fresh corn husking, but both have significant drawbacks and are unable to meet the demands of large-scale, high-quality processing:

[0003] On the one hand, some small and medium-sized processing sites still rely on manual peeling. Manual operation requires peeling the corn husks one by one by hand, which is not only labor-intensive and time-consuming, but also affected by the operator's physical strength and skill level, resulting in large fluctuations in peeling efficiency and limited processing capacity per unit time, making it difficult to meet the needs of large-scale centralized processing of fresh corn. At the same time, the manual peeling process is prone to damage to fresh corn kernels due to uneven force, or the husk residue may affect the hygiene standards of subsequent processing, further reducing product quality.

[0004] On the other hand, while existing mechanized peeling equipment has replaced manual labor to some extent, it still faces technical bottlenecks. Some machines use friction rollers to peel the corn kernels, removing the coating through friction between the rotating rollers and the corn surface. However, this method easily causes compression and abrasion to the fresh corn kernels, resulting in a high breakage rate, making it particularly unsuitable for processing fresh corn where kernel integrity is crucial. Other equipment uses a segmented processing structure, requiring separate processes for corn positioning, cutting, and peeling. These processes require manual intervention or additional conveying mechanisms for connection, resulting in a large overall footprint and reduced processing efficiency due to gaps between processes. Furthermore, segmented operation can lead to irregular cutting and incomplete peeling due to positioning deviations, making it difficult to balance processing efficiency and product precision.

[0005] In addition, existing equipment has poor adaptability to fresh corn of different specifications. When processing corn with differences in thickness and length, it is necessary to frequently adjust the clamps or equipment parameters, which is cumbersome and can easily affect the continuity of processing. Some equipment lacks an effective automated control mechanism, requiring manual monitoring of the progress of each process and manual adjustment, which further increases the complexity of operation and reliance on manpower. Therefore, this invention proposes a rotary fresh corn peeling machine to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a rotary fresh corn peeling machine.

[0007] The rotary fresh corn peeling machine provided by this invention adopts the following technical solution:

[0008] A rotary fresh corn peeling machine, featuring a housing frame with a feeding port on one side, and a drive assembly positioned along the axis of the housing frame, is characterized by the following components arranged from top to bottom:

[0009] The clamping mechanism is an elastic rod-shaped component that uses a pusher connected to the outer frame to move downwards along the Y-axis.

[0010] The clamping mechanism has a gripper at one end to hold the corn, and a mechanism for pushing and flipping the corn is located behind the gripper.

[0011] The puncture mechanism is equipped with a rotating puncture needle structure. It uses the pusher connected to the outer frame to move along the Y-axis to puncture and insert the corn in the clamping mechanism.

[0012] A positioning groove that cooperates with the feeding port is also provided between the clamping mechanism and the piercing mechanism. The positioning groove is arranged in a counterclockwise direction with a first cutting mechanism for cutting off the top of the corn and a second cutting mechanism for cutting off the bottom of the corn. The clamping mechanism rotates 180° between the first cutting mechanism and the second cutting mechanism under the action of the action mechanism.

[0013] Below the positioning groove is a high-pressure air nozzle assembly that works in conjunction with the puncture mechanism. The downward airflow from the high-pressure air nozzle assembly, combined with the rotation of the puncture needle, enables the peeling operation.

[0014] After being cut in two stages, the corn is transferred to the lower piercing mechanism, where it undergoes a journey of more than one revolution within the device.

[0015] The peeling machine is equipped with a feeding trough at the bottom, and an elastic push plate structure is also provided on the outside of the piercing mechanism. The push plate structure and the feeding trough abut against each other, pushing the corn upward to complete the feeding.

[0016] Preferably, the actuation mechanism includes a finger cylinder that directly controls the opening and closing of the gripper, and a linkage group that pushes and flips the finger cylinder and the gripper as a whole.

[0017] The linkage assembly includes a first linkage fixed to the back of the finger cylinder. A first roller and a cam assembly are provided on the outside of the first linkage to push it axially. A guide tube is coaxially provided at the front end of the first linkage. A threaded groove is opened on the guide tube. A pin fixed to the first linkage is slidably embedded in the inner side of the threaded groove. When the first linkage pushes, it pushes out the gripper and the finger cylinder. At the same time, the pin cooperates with the threaded groove to realize the 180° rotation of the gripper and the finger cylinder.

[0018] Preferably, the end of the first connecting rod is fixedly connected to the outer frame, the first roller is rotatably connected to the top of the outer frame, the cam is fixed on the outer frame, and the protruding section of the cam is set to correspond to the position of the positioning groove.

[0019] Preferably, the puncture mechanism includes a guide rail two along the Y-axis, a bracket three slidably connected on the guide rail two, a motor two fixedly connected to the top of the bracket three, a puncture rod fixedly connected to the output end of the motor two, and a limiting platform is also provided between the puncture rod and the motor two;

[0020] The vertical end of the bracket three is provided with a roller three that cooperates with the pusher two.

[0021] Preferably, the elastic push plate structure includes a push plate disposed outside the puncture rod, a slide rod three and a slide rod four vertically disposed at one end of the push plate and slidingly engaged with the support three, and a spring three sleeved on the outside of the slide rod three and in contact with the support three.

[0022] Preferably, the feeding trough is fixedly connected to the bottom end of the outer shell frame, and one end of the feeding trough is provided with an upward inclined plate. The bottom end of the slide rod three is provided with a contact block that cooperates with the inclined plate to push the push plate upward.

[0023] Preferably, the clamping mechanism includes a support frame one, a bracket two is provided on the outside of the support frame one, the support frame one and the bracket two are slidably connected by a guide rail one, and a roller two that cooperates with the push frame one is rotatably provided on the top of the bracket two.

[0024] Preferably, the front end of the second bracket is vertically fitted with the first and second slide rods, the bottom end of the first slide rod is fixed with a contact, a spring is provided between the contact and the second bracket, the bottom end of the second slide rod is fixedly connected with a sheet metal part, and a spring is provided between the sheet metal part and the second bracket.

[0025] In summary, the present invention has at least one of the following beneficial technical effects:

[0026] I. Processing Automation and Efficiency

[0027] The entire process is automated, from corn feeding, positioning, and clamping to cutting at both ends, piercing and peeling, and finally unloading. It requires minimal human intervention, reducing labor costs and avoiding efficiency fluctuations associated with manual operations.

[0028] The corn is transported within the device over a cycle of more than one round, simultaneously completing multiple processes to achieve continuous processing, significantly shortening the processing cycle, increasing the corn throughput per unit time, and adapting to the needs of large-scale processing.

[0029] II. High processing precision and product quality

[0030] The positioning groove, the protruding stage of the clamping mechanism, and the elastic contact part of the pressing mechanism work together to ensure that the corn is in a constant position to be cut; in conjunction with the 180° precise rotation of the clamping mechanism, the cut surfaces at both ends are flat and of consistent length, improving processing accuracy.

[0031] The piercing mechanism drives the corn to rotate, and combined with the downward airflow from the high-pressure nozzle group, it quickly peels off the coating and reduces wear on the corn kernels; the elastic push plate and the inclined plate of the feeding chute work together to achieve non-destructive feeding, ensuring the integrity and quality of the fresh corn.

[0051] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 The present invention will be described in further detail below.

[0052] Example 1:

[0053] Reference Figure 1 - Figure 11 A rotary fresh corn peeling machine has an outer frame 1 with a feeding port 101 on one side. The outer frame 1 is a rectangular frame structure composed of multiple profiles and sheet metal parts. The outer side of the frame is covered with sheet metal and acrylic shell. A drive assembly is set at the axis of the outer frame 1. The drive assembly includes a motor 25 and a rotating shaft connected to the end of the motor 25. The rotating shaft is used to drive the entire device and realize the operation of the entire device. The device has a transmission structure inside, which uses a transmission frame structure 2 to separate the various components. The transmission frame structure 2 includes a top frame 21, a second-layer frame 22, a third-layer frame 23 and a bottom frame 24 from top to bottom. The top frame 21 and the second-layer frame 22 are connected to each other. A clamping mechanism 6 is installed between the second-layer frame 22 and the third-layer frame 23. A clamping mechanism 3 is installed between the second-layer frame 22 and the third-layer frame 23. A trigger ring 1 221 and a trigger ring 222 are also installed between the second-layer frame 22 and the third-layer frame 23 to trigger the mechanical solenoid valve 38 and the limit switch 37 respectively. A cam 223 is installed below the trigger ring 2. The trigger ring 1 221, the trigger ring 222 and the cam 223 are all fixedly connected to the outer shell frame 1 and their positions are kept fixed. A piercing mechanism 7 is installed between the third-layer frame 23 and the base frame 24. A positioning groove 9, a cutting mechanism 1 41 and a cutting mechanism 2 42 are installed counterclockwise on the outside of the third-layer frame 23.

[0054] The peeling machines are arranged from top to bottom as follows:

[0055] The clamping mechanism 6 is an elastic rod-shaped component that uses the pusher 10 connected to the outer shell frame 1 to move downwards along the Y-axis. The structure of the pusher 10 is as follows: Figure 4 As shown, it has a trapezoidal structure that protrudes downwards. The roller 66 on the pressing mechanism 6 contacts the surface of the push frame 10, thereby realizing the downward movement of the entire pressing mechanism 6.

[0056] Clamping mechanism 3, the end of clamping mechanism 3 is provided with a gripper 35 for clamping the corn, the structure of gripper 35 is as follows Figure 4 , Figure 5 As shown, one end of the gripper is flat and open, and the other end is provided with an inward protruding platform. Behind the gripper 35, there is an action mechanism for pushing and flipping its position. The action mechanism includes a finger cylinder 36 that directly controls the opening and closing of the gripper 35, and a linkage group that pushes and flips the finger cylinder 36 and the gripper 35 as a whole.

[0057] The linkage assembly includes a connecting rod 33 fixed to the back of the finger cylinder 36. A roller 32 and a cam 223 assembly are externally mounted on the connecting rod 33 to push it axially. A guide tube 34 is coaxially mounted at the front end of the connecting rod 33. A threaded groove 341 is formed on the guide tube 34. A pin 331, which is fixed to the connecting rod 33, is slidably embedded inside the threaded groove 341. When the connecting rod 33 pushes, it pushes out the gripper 35 and the finger cylinder 36. Simultaneously, the pin 331, in conjunction with the threaded groove 341, allows the gripper 35 and the finger cylinder 36 to rotate 180°. Figure 7 As shown, the diameter of the guide tube 34 is larger than that of the connecting rod 33. The thread pitch of the threaded groove 341 on the guide tube 34 matches the extension distance of the connecting rod 33, and the number of turns is 0.5. With this setting, when the connecting rod 33 is pushed forward and the pin 331 is displaced, the pin 331 and the connecting rod 33 as a whole will rotate axially, thereby realizing the rotation of the gripper 35 and the finger cylinder 36 180°.

[0058] The end of connecting rod 33 is fixedly connected to the outer frame 31, roller 32 is rotatably connected to the top of the outer frame 31, and cam 223 is fixed to the outer frame 1. The protruding section of cam 223 is positioned corresponding to the positioning groove 9. (Refer to...) Figure 7 and Figure 10 A three-layer frame 23 is located below the clamping mechanism 3 and rotates synchronously with it. A bracket 39 is fixedly installed on the three-layer frame 23. The bracket 39 is shaped like a... Figure 7 The design shown has a guide rail on the bottom horizontal section to guide the connecting rod 33 and the outer frame 31. A vertical plate fixed to the guide tube 34 is also provided in the middle section of the bracket 39. The connecting rod 33 passes through the vertical plate and is fixedly connected to the front end of the bracket 39 and the back of the finger cylinder 36. A spring is provided between the vertical plate and the outer frame 31 to reset the connecting rod 33.

[0059] The puncture mechanism 7 is equipped with a rotating puncture needle structure. It utilizes a pusher 11 connected to the outer frame 1 to move along the Y-axis, puncturing and inserting the corn into the clamping mechanism 3. The structure of the pusher 11 is as follows: Figure 5 As shown, it has a trapezoidal structure that protrudes upwards, and the rollers 78 on the puncture mechanism 7 are in contact with its surface, so as to realize the upward movement of the entire puncture mechanism 7;

[0060] The puncture mechanism 7 includes a guide rail 711 along the Y-axis, a bracket 72 slidably connected to the guide rail 711, a motor 76 fixedly connected to the top of the bracket 72, a puncture rod 77 fixedly connected to the output end of the motor 76, and a limiting platform 771 is also provided between the puncture rod 77 and the motor 76.

[0061] The vertical end of the support frame 72 is equipped with a roller 78 that cooperates with the push frame 11. The guide rail 711 is mounted on the support frame 71, and the two ends of the support frame 71 are fixedly mounted on the three-layer frame 23 and the base frame 24, respectively. A guide rod fixed to the base frame 24 is also provided on the outside of the support frame 72. A spring is sleeved on the outside of the guide rod. The spring contacts the support frame 72 and is used to push the support frame 72 downward, thereby achieving its reset. When the roller 78 moves along the upper left side of the push frame 11, the support frame 72 moves along the Y-axis under the limit of the guide rail 711. At the top horizontal position of the push frame 11, since each piercing mechanism 7 is set one-to-one with the clamping mechanism 3 above, the piercing rod 77 will be inserted into the corn cob. When the roller 78 moves along the lower right side of the push frame 11, the support frame 72 resets along the Y-axis.

[0062] The elastic push plate 75 structure includes a push plate 75 disposed outside the puncture rod 77, a slide rod 73 and a slide rod 74 vertically disposed at one end of the push plate 75 and slidingly engaged with the support 72, and a spring 732 sleeved on the outside of the slide rod 73 and in contact with the support 72.

[0063] A positioning groove 9 that cooperates with the feeding port 101 is also provided between the clamping mechanism 3 and the piercing mechanism 7. The positioning groove 9 is provided with a cutting mechanism 41 for cutting off the top of the corn and a cutting mechanism 42 for cutting off the bottom of the corn in a counterclockwise direction. The clamping mechanism 3 rotates 180° between the cutting mechanism 41 and the cutting mechanism 42 under the action of the action mechanism.

[0064] The clamping mechanism 6 includes a support frame 61, a bracket 62 on the outside of the support frame 61, the support frame 61 and the bracket 62 are slidably connected by a guide rail 611, a roller 66 that rotatably engages with the push frame 10 is mounted on the top of the bracket 62, a top frame 21 fixed above the bracket 62 and a second-layer frame 22 fixed below the bracket 62, a guide rod is fixedly connected between the top frame 21 and the second-layer frame 22, a through hole that engages with the guide rod is provided on the bracket 62, and a spring that slides on the guide rod between the second-layer frame 22 and the bracket 62 is provided for the upward reset of the bracket 62.

[0065] The front end of bracket 2 62 is vertically fitted with slide rod 1 64 and slide rod 2 65. The bottom end of slide rod 1 64 is fixed with a contact piece. A spring 1 641 is provided between the contact piece and bracket 2 62. The bottom end of slide rod 2 65 is fixedly connected with a sheet metal part. A spring 2 651 is provided between the sheet metal part and bracket 2 62.

[0066] After the corn is cut in two stages, it is transferred to the lower piercing mechanism 7, and the corn is transported in the device for more than one round trip.

[0067] The bottom of the peeling machine is equipped with a feeding trough 8, and the outer side of the piercing mechanism 7 is also equipped with an elastic push plate 75 structure. The push plate 75 structure and the feeding trough 8 abut against each other, pushing the corn upward to complete the feeding.

[0068] The feeding trough 8 is fixedly connected to the bottom end of the outer frame 1, and one end of the feeding trough 8 is provided with an upward inclined plate 81. The bottom end of the slide bar 73 is provided with a contact block 731 that cooperates with the inclined plate 81 to push the push plate 75 upward.

[0069] When processing corn, the device initially contacts the recessed section of the mechanical solenoid valve 38 and the trigger ring 221. At this time, the gripper 35 opens under the action of the finger cylinder 36, and under the action of the cam 223 and the roller 32, the connecting rod 33 pushes the gripper 35 to the radius position of the positioning groove 9. Subsequently, during the operation of the device, the corn is manually placed upside down in the positioning groove 9, and the mechanical solenoid valve 38 on the outer frame 31 contacts the protruding section of the trigger ring 221, triggering it. At this time, the finger cylinder 36 tightens, and the gripper 35 clamps the corn.

[0070] The device continues to operate, and because the position of the positioning groove 9 is lower than the cutting plane of the cutting mechanism 41, the cutting blade cuts off the top of the corn.

[0071] Then continue running counterclockwise. At this time, roller 32 moves past the protruding section of cam 223, and connecting rod 33 resets under the action of the elastic elements of the vertical plate and the outer frame 31. At the same time, since the pin on connecting rod 33 passes through the threaded groove 341, connecting rod 33 is also retracted and rotated 180°. After rotating, the bottom of the corn faces downward.

[0072] At this time, the pressing mechanism 6 above passes the position of the push frame 10. The roller 66 on the pressing mechanism 6 contacts the push frame 10 and moves along the surface contour of the push frame 10. With the help of the springs 641 and 651 on the slide rod 64 and slide rod 65, the contact member 63 covers the bottom end of the corn. Under the action of the protrusion stage inside the gripper 35, the position of the contact member 63 is constant with each movement, thereby stabilizing the position of each corn to be cut. The corn then contacts the cutting mechanism 42 to complete the cutting of the bottom end.

[0073] As the corn is cut at the bottom, the piercing mechanism 7 located below moves upward under the action of the pusher 11, triggering the limit switch 37 via the trigger ring 222. The motor 76 rotates, driving the piercing rod 77 to rotate, facilitating its insertion into the corn cob. Finally, in the downward section of the pusher 11, it returns to the Y-axis height position under the action of the external spring and guide rod. When passing the position of the second trigger ring 222, the limit switch 37 is triggered for the second time, restarting the motor 76. At the same time, the high-pressure air nozzle group 12 located below the positioning groove 9 operates, and the high-pressure air blown out, combined with the rotation of the corn, allows its husk to be easily ejected.

[0074] When the piercing mechanism 7 carrying corn moves backward, the contact block 731 contacts the inclined plate 81 of the feeding trough 8, thereby pushing the push plate 75 upward. The push plate 75 pushes the corn off the piercing rod 77, and the fallen corn enters the feeding trough 8 under the guidance of the inclined plate 81 and is conveyed to the outside.

[0075] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
