Description

Technical Field

[0001] This utility model relates to a peeling mechanism with a conveniently detachable blade holder, which is applied in the field of peeling knives. Background Technology

[0002] A fruit peeler is a mechanical device used to peel the outer skin of fruits. Different types of fruit peelers can be designed depending on the type of fruit. Existing fruit peelers include mechanical peelers, chemical peelers, high-pressure water jet peelers, and laser peelers. Traditional peelers are spiral peelers, but even after peeling, a significant amount of peel remains on the fruit, requiring further manual peeling. Current peeler blades, such as those used in an automated mango peeler (patent publication number CN111869896B), have blade holders that are difficult to disassemble for blade replacement. Since blades are consumable parts, failure to replace them leads to low peeling efficiency. This equipment typically requires simultaneous blade replacement at eight stations; the difficulty in replacing blades wastes time and further reduces production efficiency. Therefore, this invention designs a peeling mechanism with a conveniently disassembled blade holder. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] The existing blade has a cutting edge in the middle and rotatable locking parts on both sides. The blade has an upper half and a lower half, which limit the rotation angle of the blade, allowing it to cut mangoes. This blade has a simple structure and is highly practical; however, because the peeling blade assembly of this peeling machine cuts from bottom to top, [reference...] Figure 1 As shown, when the blade is positioned at the bottom of the fruit and cutting upwards, within the blade's angle limitation range, the upper part may scrape against the fruit, causing damage. To address this problem, this utility model proposes the following:

[0031] Reference Figures 2-6As shown, a peeling mechanism with a conveniently detachable blade holder includes: a drive unit 10 and a peeling blade unit 20 driven by the drive unit 10. The peeling blade unit 20 includes a first peeling blade assembly and a second peeling blade assembly opposite to the first peeling blade assembly. The drive unit 10 includes a drive cylinder 11. The drive end of the drive cylinder 11 is connected to a first swing arm 13, and the first swing arm 13 is connected to the first peeling blade assembly. The other end of the drive cylinder 11 is provided with a sliding member 12, and the sliding member 12 is provided with a sliding groove. 121, the sliding groove 121 is slidably connected to the second swing arm 14, the first swing arm 13 is connected to the second swing arm 14 through the telescopic spring 15, and the second swing arm 14 is connected to the second peeling knife assembly. This utility model drives the first peeling knife assembly and the second peeling knife assembly to open or retract through the driving cylinder 11 to peel the fruit. This utility model adopts a simulated manual cutting method, similar to a double pendulum combination knife assembly structure. The peeled fruit has a smooth surface, and the direct-pin mechanical structure can better penetrate and fit the upper and lower surfaces of the fruit.

[0032] Reference Figure 4As shown, both the first peeler assembly and the second peeler assembly include a fixing member 21. A rotatable synchronous rotating shaft 22 is provided inside the fixing member 21 and passes through the fixing member 21. One end of the synchronous rotating shaft 22 is fixedly connected to the first swing arm 13 / second swing arm 14, and the other end of the synchronous rotating shaft 22 is connected to the first connecting rod 23. The end of the first connecting rod 23 away from the synchronous rotating shaft 22 is connected to the fixed blade holder 25. A second connecting rod 24 is also provided between the fixed blade holder 25 and the fixing member 21. The fixed tool holder 25 includes a tool holder body 251. A first snap-fit ​​hole 2511 is provided on one side wall of the tool holder body 251, and a mounting hole 2512 corresponding to the first snap-fit ​​hole 2511 is provided on the other side wall of the tool holder body 251. A first bolt 252 is fixedly provided on one side of the tool holder body 251 located at the mounting hole 2512. A hexagonal stud 253 is provided in the first bolt 252 and screwed into the mounting hole 2512. A second snap-fit ​​hole 2531 corresponding to the first snap-fit ​​hole 2511 is provided in the hexagonal stud 253. A scratch-resistant blade 30 with an arc-shaped edge is provided between the first snap-fit ​​hole 2511 and the second snap-fit ​​hole 2531. A second bolt 254 is screwed onto the outer periphery of the hexagonal stud 253. The fixed blade holder 25 is provided with a first limiting post 2513 and a second limiting post 2514. During installation, the blade 30 is first placed in the first snap-fit ​​hole 2511 and the mounting hole 2512. Then, a hexagonal stud 253 is screwed into the first bolt 252, so that the blade 30 is installed in the second mounting hole 2512. Then, a second bolt 254 is used to fix the hexagonal stud 253. The advantage of this design is that it is easy to disassemble the blade 30 for replacement. The blade 30 is fixed by the screw connection of the first bolt 252 and the hexagonal stud 253, and then the hexagonal stud 253 is fixed again by the second bolt 254, which prevents the first bolt 252 and the hexagonal stud 253 from loosening during use. This design is simple, easy to install, and only requires two bolts and one stud for installation and fixation, resulting in low cost.

[0033] Reference Figures 7-9 As shown, an anti-scratch blade 30 with a curved edge includes an integrally formed blade body 31. The blade body 31 has a strip-shaped opening 311 in the middle, which divides the blade body 31 into an upper half 33 and a lower half 34. The blade body 31 has symmetrically arranged locking parts 32 on both sides of the opening 311. The locking parts 32 are disposed in the first locking hole 2511 and the second locking hole 2531 to fix the blade 30. A blade edge 312 is provided on the side wall of the opening 311 near the lower half 34.

[0034] The upper part 33 includes a first straight portion 331 near the opening 311, and a first bent portion 332 integrally bent with the first straight portion 331. The end of the first bent portion 332 is bent to form an arc-shaped edge structure 333. The lower part 34 includes a second straight portion 341 near the opening 311, and a second bent portion 342 integrally bent with the second straight portion 341. Since the peeling mechanism of this peeler cuts from bottom to top, this design not only allows the blade 30 to have a certain degree of freedom in its rotation angle to adapt to fruits of different shapes, but also provides an edge structure 333 above the blade 30. When cutting upwards, within the angle limitation range of the blade 30, the upper part 33 prevents the fruit from being scratched by the fruit, thus preventing damage.

[0035] Reference Figure 11 As shown, in this embodiment, the length of the first straight portion 331 along the direction perpendicular to the axis of the locking portion 32 is greater than the length of the second straight portion 341 along the direction perpendicular to the axis of the locking portion 32, making the upper portion 33 longer than the lower portion 34. Therefore, the overall center of gravity of the blade 30 falls on the upper portion 33 of the blade 30. The blade 30 is fixed by the locking portion 32. Therefore, under normal circumstances, the upper portion 33 of the blade 30 abuts against the first limiting post 2513. This design further prevents the blade 30 from colliding with the fruit. Moreover, when the blade 30 cuts from bottom to top, the fruit can immediately come into contact with the blade 312, which can cleanly peel the fruit and improve the peeling efficiency.

[0036] Reference Figure 6 , Figure 9 , Figure 10 As shown, the included angle α between the first straight portion 331 and the second straight portion 341 is 110° to 120°. The included angle β between the line connecting the first limiting post 2513 and the mounting hole 2512 and the horizontal plane is 10° to 20°, and the included angle γ between the line connecting the second limiting post 2514 and the mounting hole 2512 and the horizontal plane is 30° to 45°. In this embodiment, the included angle α between the first straight portion 331 and the second straight portion 341 is 110°. The angle β between the line connecting the first limiting post 2513 and the locking hole and the horizontal plane is 12°, and the angle γ between the line connecting the second limiting post 2514 and the locking hole and the horizontal plane is 39°. Therefore, the rotation angle of the blade 30 is 110-12-39=59°. This angle setting can effectively prevent the blade 30 from rotating randomly under the limiting action of the first limiting post 2513 and the second limiting post 2514, which would cause the blade 312 to fail to contact the fruit and thus affect the cutting efficiency. At the same time, it can also effectively prevent the blade 312 from penetrating the fruit peel too deeply, thereby reducing the fruit pulp retention rate.

[0037] In this embodiment, an inclined chamfer structure 334 is symmetrically provided on both sides of the end of the edge-binding structure 333. On the one hand, it can reduce the material consumption of the blade 30 without affecting the contact of the upper half 33 of the blade 30. On the other hand, the manufacturing process of the blade 30 of this utility model is to first manufacture a straight upper half 33 and a lower half 34, then bend the first bending part 332 and the second bending part 342 by a bending machine, and then slowly bend the edge-binding structure 333 into shape by a bending machine. In this process, the inclined chamfer structure 334 can make the edge-binding structure 333 smaller in size, easier to bend, and reduce the defect rate.

[0038] As a further improvement, the first straight portion 331 is recessed inward on the side opposite to the blade 312 to form a concave portion 313. The concave portion 313 makes the opening 311 of the blade 30 larger, which can prevent the peel from remaining at the opening 311 after peeling, thus affecting the next peeling, and can also adapt to fruits with different peel thicknesses.

[0039] The locking part 32 is a locking post formed by bending a plate-like structure. Since the blade 30 of this utility model is a consumable, the locking part 32 is a locking post formed by bending a plate-like structure. Compared with the original solid structure, the material can be reduced, thereby reducing the manufacturing cost.

[0040] As a further improvement, the blade 312 has a thickness of 1.8 to 2.7 mm. The thickness of the blade 312 can be used to peel different fruits. By selecting an appropriate thickness for different varieties of fruits, not only can the peel be removed, but the flesh can be preserved to the greatest extent. The blade 312 is suitable for fruits such as winter melon, taro, mango, and radish.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
