Description

Technical Field

[0001] The invention relates to the field of mango peeling machinery, and in particular to an automatic peeling knife group suitable for multiple mangoes. Background Art

[0002] Mango is a large evergreen tree of the Anacardiaceae family native to India. Its fruit is one of the famous tropical fruits. Mango fruit contains sugar, protein and crude fiber. Mango is large in size and flattened. When ripe, it is yellow, sweet and has a hard core.

[0003] Traditional mango peeling machines use a clamp to position the upper and lower ends of the mango and rotate it. The blade fits the surface of the mango. During the rotation of the mango, the blade slowly moves along the axis of the mango, and the blade peels the mango's surface in a spiral shape, thereby removing the mango peel. However, the peeling effect of such peeling machines has the following defects: Figure 1 As shown, 1. Mangoes vary in shape and size, and there are many crooked ones. During the mechanical peeling process, it is difficult to peel the irregular parts of the mango, and the blade needs to be tightly attached to the surface of the mango; 2. The mango pulp contains more fibers, and the extension direction of the fibers is contrary to the peeling direction. There are spiral lines on the surface of the mango peeled by the traditional mango peeler; 3. The upper and lower ends of the mango are thick at one end and thin at the other end. After the traditional mango peeler peels the mango, there is still a lot of peel on the upper and lower ends, which requires further manual peeling; 4. It is impossible to peel mature mangoes.

[0004] The purpose of the present invention is to design an automatic peeling knife group suitable for multiple mangoes in view of the problems existing in the above-mentioned prior art. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides an automatic peeling knife group suitable for multiple mangoes, which can effectively solve the problems existing in the above-mentioned prior art.

[0037] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0038] refer to Figure 1-7 , an automatic peeling knife set suitable for multiple mangoes, comprising a first peeling device 1 and a second peeling device 2, the first peeling device 1 and the second peeling device 2 have the same structure, and the first peeling device 1 and the second peeling device 2 are arranged symmetrically, and the first peeling device 1 and the second peeling device 2 are driven by the same driving cylinder 8 to swing;

[0039] The first peeling device 1 comprises:

[0040] The connecting seat 3 is further provided with a connecting rod 301 running through the connecting seat 3;

[0041] The first swing rod 4 and the second swing rod 5, the upper end of the first swing rod 4 and the upper end of the second swing rod 5 are both hinged to the connecting seat 3, further, the distance between the upper hinge point and the lower hinge point of the first swing rod 4 is defined as H1, the distance between the upper hinge point and the lower hinge point of the second swing rod 5 is defined as H2, H1=H2, H1=H2=9-11cm. Specifically, in this embodiment, H1=H2=10cm. One end of the connecting rod 301 is connected to the first swing rod 5, and the other end of the connecting rod 301 is connected to a swing arm 9. The lower end of the swing arm 9 is hinged to the driving cylinder 8, and a spring 901 is connected between the swing arm of the first peeling device 1 and the swing arm of the second peeling device 2. The driving cylinder 8 is provided with a slide groove that matches one of the swing arms 9, and the slide groove is used to provide space for the swing of the swing arm 9. Furthermore, in this embodiment, the drive cylinder 8 is connected to the first peeling device 1 and the second peeling device 2 at the same height, which can ensure that the two peeling devices are subjected to tension at the same position and with the same force during the driving of the drive cylinder 8.

[0042] The blade mounting seat 6 is hinged between the bottom end of the first swing rod 4 and the bottom end of the second swing rod 5. In the present embodiment, the structure of the blade mounting seat 6 is formed by connecting two fixed plates, one in front and one in the back, and one of the fixed plates is hinged to the first swing rod 4 and the second swing rod 5. In other embodiments, the structure of the blade mounting seat 6 may also be other shapes, which are not limited here, as long as it can serve as an installation for the blade 7. Since the distances between the upper and lower hinge points of the first swing rod 4 and the second swing rod 5 are equal, during the swinging process of the first swing rod 4 and the second swing rod 5, a total of four hinge points of the first swing rod 4 and the second swing rod 5 constitute the four intersection points of a parallelogram, and the first swing rod 4, the second swing rod 5 and the blade mounting seat 6 constitute the three sides of the parallelogram. During the swinging process of the first swing rod 4 and the second swing rod 5, the blade mounting seat 6 can always swing in parallel, thereby driving the blade 7 to swing in parallel.

[0043] The blade 7 is swingably arranged on the blade mounting seat 6. In this embodiment, when the two swinging rods are vertically downward, the distance between the two blades 7 is 115-120 cm.

[0044] Further, the front and rear ends of the blade 7 include latches 703, and the blade mounting seat 6 is provided with a pin hole that matches the latch 703. Through the cooperation of the latch 703 and the pin hole, the blade 7 can swing freely within a certain angle.

[0045] Further, the blade 7 comprises an upper half 701 and a lower half 702 fixedly connected together, the angle between the upper half 701 and the lower half 702 is 125°-145°, and a blade 704 is provided on the upper end surface of the lower half 702. In this embodiment, the angle between the upper half 701 and the lower half 702 is 135°, and in other embodiments, the angle between the upper half 701 and the lower half 702 can also be 125° or 145°. At the same time, the blade 704 in this embodiment is integrally formed with the lower half 702.

[0046] Further, the blade mounting seat 6 is provided with an upper limit block 601 and a lower limit block 602, wherein the upper limit block 601 is used to limit the swing angle of the upper half 701, and the lower limit block 602 is used to limit the swing angle of the lower half 702. The line between the lower end surface of the lower limit block 602 and the blade 704 is defined as L1, and the angle between L1 and the horizontal plane is 20-25°. The line between the upper end surface of the upper limit block 601 and the blade 704 is defined as L2, and the angle between L2 and the horizontal plane is 25-30°. In this embodiment, the angle between L1 and the horizontal plane is 21°, and the angle between L2 and the horizontal plane is 26°. In other embodiments, the angle between L1 and the horizontal plane may also be 20° or 25°, and the angle between L2 and the horizontal plane is 25° or 30°. Specifically, during the swinging process of the blade 7, since the angle between the upper part 701 and the lower part 702 of the blade 7 in this embodiment is 135°, the swingable angle of the blade 7 is limited to 135°-26°-21°=88°. Swinging within this angle range, with the structure that the angle between the upper part 701 and the lower part 702 of the blade 7 is 135°, can effectively make the blade 7 suitable for the shape of the mango, and the blade 7 can always cut the peel during the movement on its surface.

[0047] During operation, the mango is positioned on the corresponding positioning device, wherein the thicker end of the mango is downward, and the two connecting seats 3 of the present invention are driven to move up and down synchronously by the corresponding driving device. Figure 8 , the drive cylinder 8 contracts, thereby controlling the two swing arms to close. Next, the drive device drives the two connecting seats 3 of the present invention to move upward synchronously. During the movement, the two blades 7 are tightened by the spring 901 and peel the mango from bottom to top along the outer surface of the mango, peeling the skin of the left and right end surfaces of the mango. When reaching the top of the mango, the drive cylinder 8 extends, thereby controlling the two swing arms to open. Finally, the rotating device drives the positioning device to rotate a certain angle, and the above movement is repeated until the mango is fully peeled.

[0048] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
