Description

Technical Field

[0001] The invention relates to a peeling and recovery device and method for water chestnut processing, belonging to the field of fruit processing. Background Art

[0002] Before deep processing of fruits, it is generally necessary to peel the fruits and sort them according to their size. However, these operations need to be performed separately. The sorting equipment and peeling equipment take up a large space. In addition, when peeling the fruits, the fixed fruits need to be rotated by the motor at the peeling station. In order to ensure efficiency, multiple peeling stations are usually set up. It is energy-wasting for multiple motors to work at the same time, so improvements have been made. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the background technology and to provide a peeling and recovery device and method for water chestnut processing.

[0004] The present invention achieves the above-mentioned purpose by adopting the following technical solutions:

[0005] A peeling and recovery device for processing water chestnuts, comprising two bottom plates; the bottom plates are arc-shaped and concentric; a peeling device is provided at the upper end of the bottom plates, and a rotating device fixedly connected to a base is provided at the center of the bottom plates;

[0006] The peeling device includes an outer arc plate, an inner arc plate, an outer arc baffle and an inner arc baffle; the outer arc plate is located at the outer circular surface of the outer bottom plate, and the inner arc plate is located at the inner circular surface of the inner bottom plate; the outer arc baffle is located at the inner circular surface of the outer bottom plate, and the inner arc baffle is located at the outer circular surface of the inner bottom plate;

[0007] The rotating device includes a motor fixedly connected to the base body; the output shaft of the motor is fixedly connected to a connecting rod; the side of the connecting rod is fixedly connected to multiple rotating rods; the lower end of each rotating rod is provided with two sliding grooves; each sliding groove is provided with a slider that slides together with it; a spring is fixedly connected between the inner walls of the sliding groove of the slider, and the lower end of the slider is fixedly connected to a fruit inserter.

[0008] A method for using a peeling and recovery device for water chestnut processing, the method comprising the following steps:

[0009] Step 1: Workers cut off the roots at the top of the fruit and place the fruit in the groove on the conveyor belt;

[0010] Step 2: Start the stepper motor on the side of the conveyor belt to drive the fruit to move. When the fruit moves to a position close to the bottom plate, the conveyor belt stops moving. After the rotating rod moves above the fruit, the position sensor feeds back a signal to the controller, and the controller drives the electric telescopic rod to stretch, so that the insertion rod is inserted into the fruit.

[0011] Step 3: The motor drives the rotating rod to rotate, and pushes the two fruit inserters to move in opposite directions through the outer arc baffle and the inner arc baffle, and compresses the spring;

[0012] Step 4: The fruit is placed against the outer arc baffle and the inner arc baffle. Driven by the rotating rod, the fruit rotates due to the friction between the outer arc baffle and the inner arc baffle. When the fruit contacts the scraper, the outer skin of the fruit is scraped off.

[0013] Step 5: After the rotating rod moves above the collection trough, feedback from the position sensor drives the electric telescopic rod to retract, causing the fruit to pass through multiple retaining rings in sequence. As the rotating rod rotates, the difference in contact time between the retaining rings at different heights and the fruit causes fruits of different sizes to fall into different collection troughs. Compared with the existing technology, the present invention has the following advantages: it not only reduces the number of station motors and energy consumption, but also allows for post-peel fruit screening by size, reducing equipment space and saving factory construction funds.

[0021] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Specific implementation method 1: Figure 1-7 As shown, this embodiment describes a peeling and recovery device for processing water chestnuts, comprising two bottom plates 3; the bottom plates 3 are configured to be arc-shaped and concentric; a peeling device 4 is provided at the upper end of the bottom plates 3, and a rotating device 8 fixedly connected to a base 7 is provided at the center of the bottom plates 3;

[0023] The peeling device 4 includes an outer arc plate 41, an inner arc plate 42, an outer arc baffle 47 and an inner arc baffle 48; the outer arc plate 41 is located at the outer circular surface of the outer bottom plate 3, and the inner arc plate 42 is located at the inner circular surface of the inner bottom plate 3; the outer arc baffle 47 is located at the inner circular surface of the outer bottom plate 3, and the inner arc baffle 48 is located at the outer circular surface of the inner bottom plate 3; the outer arc baffle 47 and the inner arc baffle 48 are close to the fruit 2 to provide friction so that the fruit 2 can be rotated for peeling.

[0024] The rotating device 8 includes a motor 81 fixedly connected to the base body 7; the output shaft of the motor 81 is fixedly connected to a connecting rod 82; a plurality of rotating rods 83 are fixedly connected to the side of the connecting rod 82; the lower end of each rotating rod 83 is provided with two slide grooves 85; each slide groove 85 is provided with a slider 86 that slides together with it; a spring 87 is fixedly connected between the inner walls of the slide groove 85 of the slider 86, and the lower end of the slider 86 is fixedly connected to a fruit inserter 88.

[0025] When the spring 87 is at its original length, the distance between the two fruit inserters 88 is smaller than the distance between the outer arc baffle 47 and the inner arc baffle 48. When the fruit 2 at the lower end of the fruit inserter 88 contacts the outer arc baffle 47 and the inner arc baffle 48, it can move in the opposite direction and compress the spring 87, providing pressure to increase friction.

[0026] The outer arc plate 41 and the inner arc plate 42 are both provided with through holes 43 ; a vertically arranged shaft 45 is fixedly connected in each through hole 43 ; the shaft 45 is connected to a U-shaped scraper 44 via a return coil spring 46 ; the scraper 44 is located above the bottom plate 3 .

[0027] The scrapers 44 on the outer arc plate 41 and the inner arc plate 42 are arranged sequentially from bottom to top, and the coverage areas of adjacent scrapers 44 on the fruit 2 partially overlap, so that the multiple scrapers 44 can scrape the peel of the fruit 2 at different positions.

[0028] A V-shaped plate 49 is fixedly connected between one of the ends of the outer arc baffle 47 and the inner arc baffle 48. By the V-shaped plate 49, the fruits 2 at the lower ends of the fruit inserter 88 are more easily separated and are not close to the outer arc baffle 47 and the inner arc baffle 48 respectively.

[0029] A conveyor belt 1 is provided at one end of the bottom plate 3 close to the V-shaped plate 49; a groove 11 for positioning fruits is provided on the conveyor belt 1.

[0030] The fruit inserter 88 comprises an electric telescopic rod 881. The fixed end of the electric telescopic rod 881 is fixedly connected to the lower end of the slider 86. The free end of the electric telescopic rod 881 is fixedly connected to a connecting tube 884. The lower end of the connecting tube 884 is connected to a round rod 885 via a bearing. The lower end of the round rod 885 is fixedly connected to an inserting rod 886. A plurality of vertically arranged limiting rings 883 are fixedly connected to the outer circumference of the fixed end of the electric telescopic rod 881 via a bracket 882. The inner diameters of the limiting rings 883 increase from top to bottom. A position sensor 84 is provided at the upper end of the rotating rod 83. The limiting rings 883 with different inner diameters are used to select fruits of different sizes. Because the limiting rings 883 have different vertical heights, the height differences are converted into time differences during the retraction of the electric telescopic rod 881, ensuring that fruits 2 of different sizes contact the limiting rings 883 with corresponding inner diameters at different times, allowing them to fall into different collection troughs 6.

[0031] The end of the bottom plate 3 away from the conveyor belt 1 is provided with a plurality of collecting grooves 6 in an arc shape.

[0032] The outer circumferential surface of the outer arc-shaped baffle 47 and the inner circumferential surface of the inner arc-shaped baffle 48 are both provided with a plurality of vertical protrusions 471. The cross-section of the protrusions 471 is triangular, so that when the tips of the triangular protrusions 471 come into contact with the fruit 2, they leave indentations on the outer skin of the fruit 2, thereby preventing the scraper 44 from sliding on the surface of the fruit 2 and affecting the peeling.

[0033] A method for using a peeling and recovery device for water chestnut processing, the method comprising the following steps:

[0034] Step 1: The worker cuts off the root stem at the top of the fruit 2 and places the fruit 2 in the groove 11 on the conveyor belt 1;

[0035] Step 2: Start the stepper motor on the side of the conveyor belt 1 to drive the fruit 2 to move. When the fruit 2 moves to a position close to the bottom plate 3, the conveyor belt 1 stops moving. After the rotating rod 83 moves above the fruit 2, the position sensor 84 feeds back a signal to the controller, which drives the electric telescopic rod 881 to extend, so that the insertion rod 886 is inserted into the fruit 2.

[0036] Step 3: The motor 81 drives the rotating rod 83 to rotate, and pushes the two fruit inserters 88 to move in opposite directions through the outer arc baffle 47 and the inner arc baffle 48, and compresses the spring 87;

[0037] Step 4: The fruit 2 is placed against the outer arc baffle 47 and the inner arc baffle 48. Driven by the rotating rod 83, the fruit 2 rotates due to the friction between the outer arc baffle 47 and the inner arc baffle 48. When the fruit 2 contacts the scraper 44, the outer skin of the fruit 2 is scraped off.

[0038] Step 5: After the rotating rod 83 moves to the top of the collecting trough 6, the feedback signal from the position sensor 84 drives the electric telescopic rod 881 to contract, so that the fruit 2 passes through multiple limit rings 883 in sequence. As the rotating rod 83 rotates, under the influence of the contact time difference between the limit rings 883 at different heights and the fruit 2, fruits 2 of different sizes fall into different collecting troughs 6.

[0039] The working principle of the present invention is as follows: a worker cuts off the root stem at the upper end of the fruit 2 and places the fruit 2 in the groove 11 on the conveyor belt 1;

[0040] The stepper motor on the side of the conveyor belt 1 is started to drive the fruit 2 to move. When the fruit 2 moves to a position close to the bottom plate 3, the conveyor belt 1 stops moving. After the rotating rod 83 moves above the fruit 2, the motor 81 stops, and the position sensor 84 feeds back a signal to the controller, which drives the electric telescopic rod 881 to stretch, so that the insertion rod 886 is inserted into the fruit 2.

[0041] Then the motor 81 is started again to drive the rotating rod 83 to rotate, so that the two fruit inserters 88 below the rotating rod 83 move together. After the fruits 2 below the two fruit inserters 88 touch the V-shaped plate 49, the V-shaped plate 49 drives the fruits 2 on both sides to move in the opposite direction, thereby driving the corresponding fruit inserters 88 to move in the opposite direction and compressing the spring 87. Under the elastic force of the spring 87, the fruits 2 are respectively pressed against the outer circular surface of the outer arc baffle 47 and the inner circular surface of the inner arc baffle 48;

[0042] The fruit 2 is close to the outer arc baffle 47 and the inner arc baffle 48. Driven by the rotating rod 83, the fruit 2 rotates through the friction between the outer arc baffle 47 and the inner arc baffle 48, thereby driving the insertion rod 886 and the round rod 885 to rotate. At the same time, the fruit 2 will contact the scraper 44 as the rotating rod 83 moves, and push the scraper 44 to rotate around the shaft 45. In the process of the fruit 2 rotating with the round rod 885 as the axis, the scraper 44 will peel off the outer skin of the fruit 2; the scraper 44 has different heights, and can peel off the peel of the fruit 2 at different heights; in the above way, only one motor 81 is needed to peel the fruit 2, which effectively saves energy.

[0043] After the rotating rod 83 moves to above the collecting trough 6, the feedback signal from the position sensor 84 drives the electric telescopic rod 881 to retract, and the electric telescopic rod 881 drives the cylinder 884, the round rod 885 and the insertion rod 886 to move upward, thereby driving the fruit 2 to move upward, so that the fruit 2 passes through multiple limit rings 883 in sequence. Since the inner diameter of the lowest limit ring 883 is the largest and the inner diameter decreases from bottom to top, fruits 2 of different sizes will be blocked by the limit ring 883 at the corresponding limit ring 883 position and break away from the insertion rod 886; and under the influence of the contact time difference between the limit rings 883 and the fruits 2 at different heights, fruits 2 of different sizes fall into different collecting troughs 6 to complete sorting. The present invention integrates peeling and screening, effectively reducing the factory space occupied by existing peeling equipment and screening equipment on the market.
