Description

Technical Field

[0001] This invention relates to the field of yam peeling technology, specifically to a yam peeling device. Background Technology

[0002] In the fields of food processing and traditional Chinese medicine processing, yam is a common food and medicinal material. Peeling is one of the key steps in its pre-processing. With the increasing demand for industrial production, the traditional manual peeling method is no longer able to meet the requirements of large-scale production due to problems such as low efficiency, high labor intensity and unstable peeling quality. Various yam peeling devices have emerged as a result.

[0003] Existing yam peeling equipment generally suffers from poor adaptability, making it difficult to meet the precise peeling requirements of yams of different sizes and those with fluctuating surface dimensions. Specifically, on the one hand, the peeling blades or friction components in existing equipment are mostly fixed or can only be manually adjusted within a small range. When processing yams with significant diameter differences, frequent manual shutdowns are required to adjust the equipment parameters, which is not only cumbersome and affects production efficiency, but also prone to over-peeling (resulting in raw material waste) or incomplete peeling (requiring secondary processing) due to adjustment deviations. On the other hand, even for the same batch of yams, there may be slight dimensional fluctuations on their surface (such as localized unevenness in thickness), and existing equipment lacks adaptive adjustment capabilities. The peeling components cannot adapt to the changes in the yam surface in real time, resulting in poor peeling quality stability and making it difficult to ensure the uniformity of yam products in industrial production. Summary of the Invention

Each set of conveying components includes two conveying rods arranged symmetrically at the top and bottom. Two symmetrical limiting plates are fixedly connected to the outer wall of the conveying rods.

A rubber cylinder is sleeved on the outer wall of each support tension spring. Velcro is glued to the outer wall of the multiple rubber cylinders. Each peeling component is respectively arranged after each set of conveying components.

[0008] Preferably, the outer wall of the limiting plate is provided with a placement groove, the inner wall of the placement groove is fixedly connected to a miniature electric telescopic rod, the telescopic end of the miniature electric telescopic rod is fixedly connected to a lower pressure plate, and the bottom end of the lower pressure plate is fixedly connected to a plurality of lower pressure tips, which are used to fix Velcro.

[0009] Preferably, a drive motor is fixedly connected to the outer wall of the peeling box, and the output end of the drive motor is used to drive one of the conveying rods. A gear set is connected between the two conveying rods in the same group, and a belt drive structure is connected between the conveying rollers on the same horizontal plane.

[0010] Preferably, the peeling assembly further includes an electromagnetic plate fixedly connected to the inner wall of the chute, a plastic spring fixedly connected to the outer wall of the electromagnetic plate, a permanent magnet plate fixedly connected to the other end of the plastic spring, the outer wall of the permanent magnet plate being fixedly connected to the outer wall of the elastic plate, the electromagnetic plate and the permanent magnet plate being magnetically attracted to each other, and the PLC controller being electrically connected to the electromagnetic plate to form a control loop.

[0012] Preferably, the top of the closed door is provided with an adjustment groove, the other end of the rotating rod extends rotatably into the adjustment groove and is fixedly connected to a rotating gear, the top of the closed door is provided with a moving groove, the inner wall of the moving groove is fixedly connected to a moving plate, the top of the moving plate is fixedly connected to a toothed plate, the toothed plate meshes with the moving gear, the top of the toothed plate is fixedly connected to a connecting block, the top of the closed door is fixedly connected to an installation block, the outer wall of the installation block is fixedly connected to a drive electric telescopic rod, and the telescopic end of the drive electric telescopic rod is fixedly connected to the outer wall of the connecting block.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0014] 1. Relying on a precise and adaptable structure, the peeling blade is always in close contact with the material surface, effectively avoiding incomplete peeling due to insufficient contact and over-peeling due to improper adjustment, thus ensuring the stable peeling quality of individual yams. On the other hand, the peeling mechanism has a difference in tilt angle between each group of adjacent peeling components. When the material is conveyed, it will pass through components at different angles in sequence, allowing the blade to peel the yam from multiple directions. At the same time, the unified adjustment mechanism further ensures the uniformity of peeling quality of the same batch of yams, which can meet the needs of industrial production, thereby solving the problems of over-peeling (causing raw material waste) or incomplete peeling (requiring subsequent secondary processing) that are prone to occur during the yam peeling process.

[0015] 2. The "detection + two-stage adjustment" structure improves the adaptability of existing devices: In the conveying and detection mechanism, the material squeezes the conveying rollers, causing the conductive sheet to slide on the resistance plate. The resulting sliding rheostat and PLC controller form a detection circuit, and the PLC can accurately determine the material diameter through current changes. The two-stage adjustment of the peeling component further complements this. The first-stage adjustment is achieved by the PLC controlling the current of the electromagnetic plate based on the detected diameter. Through the magnetic attraction with the permanent magnet plate, the elastic plate slides within a wide range in the chute, initially adjusting the cutter head to the suitable range. The second-stage adjustment utilizes the elasticity of the elastic plate itself to cope with slight dimensional fluctuations or conveying deviations on the material surface, achieving small-amplitude fine-tuning of the cutter head. The entire process does not require manual shutdown, greatly improving adaptability. Attached Figure Description

Multiple water outlet pipes 56 are fixedly connected to the outer wall of the water supply pipe 55. The other end of the water outlet pipe 56 is connected to a spray head 53.

[0036] The top of the closed door 4 is fitted with an adjustment groove 57. The other end of the rotating rod 52 extends into the adjustment groove 57 and is fixedly connected to a rotating gear 58. The top of the closed door 4 is provided with a moving groove 59. A moving plate 510 is fixedly connected to the inner wall of the moving groove 59. A toothed plate 511 is fixedly connected to the top of the moving plate 510. The toothed plate 511 meshes with the moving gear. A connecting block 512 is fixedly connected to the top of the toothed plate 511. An installation block 513 is fixedly connected to the top of the closed door 4. A drive electric telescopic rod 514 is fixedly connected to the outer wall of the installation block 513. The telescopic end of the drive electric telescopic rod 514 is fixedly connected to the outer wall of the connecting block 512.

[0037] The working principle of this invention is as follows: When using this peeling equipment to peel materials, the material to be peeled is first placed in the feeding box 64. The material falls from the feeding box 64 into the feeding rack 61. Then, the feeding electric telescopic rod 62 on the inner wall of the feeding rack 61 is activated. The feeding electric telescopic rod 62 extends and drives the pusher plate 63 to move. The pusher plate 63 pushes the material along the feeding rack 61 towards the feed inlet 2 of the peeling box 1, so that the material enters the peeling box 1 through the feed inlet 2 and contacts the conveying roller 654 of the conveying detection mechanism 6. At this time, the miniature electric telescopic rod 727 in the placement groove 726 of the limiting plate 723 is activated. The miniature electric telescopic rod 727 extends and drives the lower pressure plate 728 to move down. The lower pressure plate 728 fixes the hook and loop fastener 725 to prevent the hook and loop fastener 725 from shifting or loosening during the contact and friction with the material. This ensures that the hook and loop fastener 725 is in stable contact with the material so that the material moves with the conveying rod 721, realizing the stable conveying of the material to the subsequent peeling component 71.

[0038] When the material enters between the two conveying rollers 654, it will squeeze the mounting brackets 653 on both sides. The mounting brackets 653 compress the mounting springs 652 in the connecting grooves 651 and move. The movement of the mounting brackets 653 causes the conductive plate 656 at the top to slide at the bottom of the resistance plate 657. Since the conductive plate 656 and the resistance plate 657 form a sliding rheostat, and the sliding rheostat is electrically connected to the PLC controller to form a detection circuit, the resistance of the sliding rheostat will change with the sliding of the conductive plate 656. The PLC controller can accurately determine the diameter of the material to be peeled by detecting the change in current in the detection circuit.

[0039] At the same time, the micro motor 655 at the bottom of the mounting frame 653 is started. The micro motor 655 drives the conveyor roller 654 to rotate. The conveyor roller 654, which is on the same horizontal plane, rotates synchronously through the belt drive structure 75. The rotation of the conveyor roller 654 conveys the material to the peeling mechanism 7 inside the peeling box 1.

[0040] After the material is conveyed to the peeling mechanism 7, the drive motor 73 on the outer wall of the peeling box 1 is started. The output end of the drive motor 73 drives the conveying rod 721 connected to it to rotate. The two conveying rods 721 in the same group are connected by a gear set 74, so that the two conveying rods 721 in the same group rotate synchronously. When the conveying rod 721 rotates, the rubber cylinder 722 on the outside of the support spring 724 between the limiting plates 723 on its outer wall comes into contact with the material. The Velcro 725 on the outer wall of the rubber cylinder 722 can increase the friction with the material.

[0041] Based on the material diameter information detected by the PLC controller, the PLC controller sends a control signal to the electromagnetic plate 716 of the peeling assembly 71. The current of the electromagnetic plate 716 is adjusted to achieve a wide range of adjustment: because the electromagnetic plate 716 and the permanent magnet plate 718 are magnetically attracted, the strength of the electromagnetic plate 716 changes with the current. This, in turn, causes the permanent magnet plate 718 to drive the elastic plate 714 to slide significantly within the groove 713 of the peeling ring 712, initially adjusting the peeling head 715 to a range roughly compatible with the material diameter. The elastic plate 714 itself is elastic, allowing for smaller adjustments based on the wide range of adjustment by the electromagnetic plate 716. When there are slight dimensional fluctuations on the material surface or minor positional deviations during transport, the elastic plate 714 uses its own elastic deformation to drive the peeling head 715 to make small adjustments, ensuring that the peeling head 715 always remains in contact with the material surface, achieving a precise peeling effect.

[0042] Furthermore, each set of peeling components 71 that are close to each other has a 90-degree tilt angle difference. During the material conveying process, the material will pass through peeling components 71 with different tilt angles in sequence. The peeling head 715 performs a comprehensive peeling operation on the material from different directions, effectively improving the thoroughness of peeling.

[0043] While the peeling operation is underway, the drive electric telescopic rod 514 of the cleaning mechanism 5 is activated, driving the electric telescopic rod 514 to reciprocate back and forth, which in turn drives the connecting block 512 to reciprocate back and forth. The connecting block 512 drives the toothed plate 511 to reciprocate back and forth synchronously along the moving groove 59 of the closed door 4. Since the toothed plate 511 meshes with the rotating gear 58 that extends from the rotating rod 52 into the adjusting groove 57, the reciprocating movement of the toothed plate 511 will drive the rotating gear 58 to rotate alternately in both directions, thereby causing the rotating rod 52 to rotate alternately in both directions synchronously in the cleaning port 51, realizing the reciprocating adjustment of the spray angle of the water spray head 53 at the end of the rotating rod 52. At the same time, the external water supply unit supplies water to each water outlet pipe 56 through the water supply pipe 55. The water flows through the water outlet pipe 56 into the water spray head 53. During the reciprocating adjustment of the angle, the water spray head 53 sprays water evenly to different areas inside the peeling box 1, thoroughly rinsing the skin flakes generated during the peeling process. The rinsed wastewater and skin flakes can be discharged through the outlet of the peeling box 1.
