Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of anti-scratching blade with arc edge covering, applied to fruit and vegetable peeling equipment field. BACKGROUND

[0002] Peeling machine blade is an important component used in peeling machine, which is responsible for contacting with fruits and vegetables and peeling off the skin. The current peeling machine blade, such as the one mentioned in patent publication No. CN111869896B, has a blade edge in the middle, with a rotatable clamping part on both sides of the blade. The blade has an upper half and a lower half, which limits the rotation angle of the blade, allowing it to cut mangoes. The blade structure is simple and practical. However, since the peeling knife set of the peeling machine cuts from bottom to top, as shown in the reference Figure 1 , the blade is just at the bottom of the fruit, and the upper half may scratch the fruit when cutting upwards within the angle limit of the blade, causing damage to the fruit. Therefore, to solve the above problems, the utility model designs an anti-scratching blade with arc edge covering. SUMMARY

[0003] The utility model provides an anti-scratching blade with arc edge covering, which can effectively solve the above problems.

[0004] The utility model is implemented as follows:

[0005] An anti-scratching blade with arc edge covering includes an integrally formed blade body, a strip-shaped opening is provided in the middle of the blade body, the opening separates the blade body into an upper half and a lower half, clamping parts are symmetrically arranged on the two side walls of the opening in the blade body, a blade edge is provided on the side wall of the opening close to the lower half,

[0006] The upper half includes a first flat part close to one end of the opening and a first bent part integrally formed with the first flat part, the end of the first bent part is bent to form an edge covering structure with an arc, and the lower half includes a second flat part close to one end of the opening and a second bent part integrally formed with the second flat part.

[0007] As a further improvement, the length of the first flat part perpendicular to the axis of the clamping part is greater than the length of the second flat part perpendicular to the axis of the clamping part.

[0008] As a further improvement, an inclined chamfer structure is symmetrically arranged on both sides of the end of the edge covering structure.

[0009] As a further improvement, the first flat portion is recessed inwardly on the opposite side of the blade to form an inner recess.

[0010] As a further improvement, the clamping portion is a clamping column bent from a plate structure.

[0011] As a further improvement, the thickness of the blade is 1.8-2.7mm.

[0012] As a further improvement, the included angle between the first flat portion and the second flat portion is 110-120°.

[0013] The beneficial effects of the present application are:

[0014] (1) Since the peeling mechanism of the peeling machine cuts from bottom to top, the design not only allows the blade to have a certain degree of freedom in the turning angle, but also adapts to fruits of different shapes, and the blade is provided with a hemming structure above, which prevents the upper half from scratching the fruit and causing damage to the fruit within the angle limit of the blade when cutting upward.

[0015] (2) The length of the first flat portion along the direction perpendicular to the axis of the clamping portion is greater than the length of the second flat portion along the direction perpendicular to the axis of the clamping portion, so that the upper half is longer than the lower half. Therefore, the overall center of gravity of the blade falls on the upper half of the blade, and the blade is fixed by the clamping portion. Therefore, under natural conditions, the upper half of the blade abuts against the first limiting column, which further prevents the blade from colliding with the fruit. Moreover, when the blade cuts from bottom to top, the fruit can first abut against the blade, which can peel the fruit cleanly and improve the peeling efficiency. BRIEF DESCRIPTION OF DRAWINGS

Meanwhile, the straight pin mechanical structure can extend into and fit the upper and lower surfaces of the fruit.

[0033] Referring to Figure 4As shown, the first peeler assembly and the second peeler assembly each include a fixing member 21, a synchronous rotating shaft 22 is arranged in the fixing member 21 and penetrates the fixing member 21, one end of the synchronous rotating shaft 22 is fixedly connected with the first swing arm 13 / the second swing arm 14, the other end of the synchronous rotating shaft 22 is connected with a first connecting rod 23, one end of the first connecting rod 23 away from the synchronous rotating shaft 22 is connected with a fixed knife holder 25, and a second connecting rod 24 is further arranged between the fixed knife holder 25 and the fixing member 21. The fixed knife holder 25 includes a knife holder main body 251, a first clamping hole 2511 is arranged on one end of the side wall of the knife holder main body 251, a mounting hole 2512 corresponding to the first clamping hole 2511 is arranged on the other end of the side wall of the knife holder main body 251, a first bolt 252 is fixed on one side of the knife holder main body 251 at the mounting hole 2512, a hexagonal stud 253 is arranged in the first bolt 252 and is screwed with the mounting hole 2512, a second clamping hole 2531 corresponding to the first clamping hole 2511 is arranged in the hexagonal stud 253, a scratch-proof blade 30 with an arc edge is arranged between the first clamping hole 2511 and the second clamping hole 2531, and a second bolt 254 is screwed on the outer periphery of the hexagonal stud 253. The fixed knife holder 25 is provided with a first limiting column 2513 and a second limiting column 2514, during installation, the blade 30 is arranged in the first clamping hole 2511 and the mounting hole 2512, then the hexagonal stud 253 is screwed into the first bolt 252, so that the blade 30 is installed in the second mounting hole 2512, and then the second bolt 254 is used to fix the hexagonal stud 253. The advantage of this arrangement is that the blade 30 can be easily disassembled and replaced. The blade 30 is fixed by screwing the first bolt 252 and the hexagonal stud 253, and then the hexagonal stud 253 is fixed again by the second bolt 254, so that the first bolt 252 and the hexagonal stud 253 are prevented from loosening during use. The design is simple and convenient to install, and only two bolts and a stud are needed for installation and fixation, which is low in cost.

[0034] Referring to Figures 7-9 As shown, a scratch-proof blade 30 with an arc edge includes a blade main body 31 formed integrally, a strip-shaped opening 311 is arranged in the middle of the blade main body 31, the opening 311 divides the blade main body 31 into an upper half 33 and a lower half 34, clamping portions 32 are symmetrically arranged on the two side walls of the blade main body 31 at the opening 311, the clamping portions 32 are arranged in the first clamping hole 2511 and the second clamping hole 2531 to fix the blade 30, and a blade edge 312 is arranged on the side wall of the lower half 34 close to the opening 311.

[0035] The upper half 33 includes a first flat portion 331 near one end of the opening 311, and a first bent portion 332 integrally formed by bending the first flat portion 331. The end of the first bent portion 332 is bent to form a rabbet structure 333 with an arc. The lower half 34 includes a second flat portion 341 near one end of the opening 311, and a second bent portion 342 integrally formed by bending the second flat portion 341. Since the peeling mechanism of the peeler is designed to cut from bottom to top, the design not only allows the blade 30 to have a certain degree of freedom in the turning angle, but also adapts to fruits of different shapes. In addition, the rabbet structure 333 is provided above the blade 30, which prevents the upper half 33 from scratching the fruit and causing damage to the fruit within the angle limit of the blade 30 when cutting upward.

[0036] Referring to Figure 11 In the present embodiment, the length of the first flat portion 331 perpendicular to the axis of the clamping portion 32 is greater than the length of the second flat portion 341 perpendicular to the axis of the clamping portion 32, so that the upper half 33 is longer than the lower half 34. Therefore, the overall center of gravity of the blade 30 falls on the upper half 33 of the blade 30. Since the blade 30 is fixed by the clamping portion 32, the upper half 33 of the blade 30 naturally abuts against the first limiting column 2513. This design further prevents the blade 30 from colliding with the fruit, and when cutting from bottom to top, the fruit can first abut against the cutting edge 312, which can effectively peel the fruit and improve the peeling efficiency.

[0037] Referring to Figure 6 , Figure 9 , Figure 10 As shown, the included angle α between the first flat portion 331 and the second flat portion 341 is 110-120°. The included angle β between the line connecting the first limiting column 2513 and the mounting hole 2512 and the horizontal plane is 10-20°, and the included angle γ between the line connecting the second limiting column 2514 and the mounting hole 2512 and the horizontal plane is 30-45°. In the present embodiment, the included angle α between the first flat portion 331 and the second flat portion 341 is 110°. The included angle β between the line connecting the first limiting column 2513 and the clamping hole and the horizontal plane is 12°, and the included angle γ between the line connecting the second limiting column 2514 and the clamping hole and the horizontal plane is 39°. Therefore, the turning angle of the blade 30 is 110-12-39=59°. This angle setting can effectively prevent the blade 30 from turning randomly under the limiting action of the first limiting column 2513 and the second limiting column 2514, which can prevent the cutting edge 312 from not abutting against the fruit and thus affecting the cutting efficiency, and can also effectively prevent the cutting edge 312 from cutting too deep into the peel and thus reducing the fruit flesh retention rate.

[0038] In the embodiment, the edge covering structure 333 is symmetrically provided with an inclined chamfer structure 334 on both sides of the end, which can reduce the consumption of the blade 30 on the one hand without affecting the abutment of the upper half 33 of the blade 30, and on the other hand, the manufacturing process of the blade 30 of the utility model is to manufacture the straight upper half 33 and the lower half 34 first, then bend the first bending part 332 and the second bending part 342 through the bending machine, and then slowly bend the edge covering structure 333 into shape through the bending machine, in the process, the inclined chamfer structure 334 can make the size of the edge covering structure 333 smaller, easy to bend and reduce the defective rate.

[0039] As a further improvement, the first straight part 331 is recessed inward to form an inner recess 313 on the opposite side of the blade edge 312, which makes the opening 311 of the blade 30 larger, prevents the peel from remaining at the opening 311 after cutting, and further affects the next peeling, and can also adapt to fruits of various peel thicknesses.

[0040] The clamping part 32 is a clamping column bent from a plate structure, since the blade 30 of the utility model is a consumable, the clamping part 32 is a clamping column bent from a plate structure, which can reduce the material compared with the original solid structure, thereby reducing the manufacturing cost.

[0041] As a further improvement, the thickness of the blade edge 312 is 1.8-2.7mm, which can peel different fruits, select appropriate thickness size for different varieties of fruits, not only can peel the peel, but also can maximize the fruit pulp, and the blade edge 312 is suitable for, for example, winter melon, taro, mango, radish, etc.

[0042] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model, for those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
