Description

Technical Field

[0001] This utility model relates to the technical field of vegetable processing equipment, specifically an onion peeling device. Background Technology

[0002] Onions, scientifically known as Allium spp., are a widely cultivated and consumed vegetable worldwide. They can be used as a seasoning or a main ingredient in dishes, and are beloved for their unique pungent flavor and aroma. Currently, onions need to have their outer skin removed before further processing, requiring specialized peeling equipment.

[0003] For example, CN207201999U discloses a swing-type air-jet onion peeler, including a frame; an arc-shaped grinding roller assembly is provided inside the frame; a motor I is fixedly installed above the frame, which drives and connects to the grinding roller assembly; a stainless steel needle brush is provided at the bottom of the grinding roller assembly; a bracket is welded and fixed at each end of the frame; a high-pressure air pipe is movably connected to the middle of the two brackets; two air jets are provided below the high-pressure air pipe, both of which are connected to the high-pressure air pipe at both ends; a motor II is also fixed above the frame, which is movably connected to an eccentric rocker arm; a rocker arm is movably connected to the other end of the eccentric rocker arm, and the other end of the rocker arm is movably connected to the air jets.

[0004] The aforementioned oscillating air-jet onion peeling machine uses a high-pressure air pipe to spray compressed air through a jet pipe with nozzles. The resulting airflow, along with the pendulum motion of the jet pipe, penetrates the gaps in the onion's outer skin, peeling it off. Because the peeling rollers are driven sequentially by gears, the relative motion between adjacent rollers throws the peeled onion skins out of the machine frame, completing the onion peeling process. However, this results in a large amount of onion skins remaining inside the machine frame, requiring manual cleaning later, which increases the labor intensity. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an onion peeling device to solve the problem mentioned in the background art that after the existing onion peeling machine completes the peeling of onions, a large amount of onion skins will be left on the inner side of the machine frame, which requires manual cleaning later, increasing the labor intensity of manual labor.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An onion peeling device includes two sets of parallel support legs, with a support plate fixedly connected to the upper end of each support leg. From left to right, a peeling assembly, a peeling assembly, and an air blowing assembly are arranged on the support plate.

[0008] Specifically, the skin collection assembly includes a collection port, one end of which is fixedly connected to a collection box. The bottom of the collection box is provided with an openable bottom cover, and several guide holes are provided on the side wall of the collection box.

[0009] Specifically, the air blowing assembly includes a flow divider. Two upper side plates are symmetrically connected to the upper end of the flow divider. The upper ends of the upper side plates are fixedly connected to a top plate. Two lower side plates are symmetrically connected to the lower end of the flow divider. The lower ends of the lower side plates are fixedly connected to a bottom plate. Air duct plate a is fixedly connected to the same end of the top plate and the bottom plate. The same end of the upper side plate and the lower side plate on the same side is fixedly connected to air duct plate b. Air duct plate a and air duct plate b together form a ventilation duct. A fan installed on a support plate is connected to the end of the ventilation duct away from the peeling assembly.

[0010] Specifically, the peeling assembly includes two side plates fixedly connected to the support plate, and several peeling rollers are horizontally arranged between the side plates. The two ends of the peeling rollers are rotatably connected to the side plates through rotating shafts. A gear is fixedly installed on one of the rotating shafts, and adjacent gears mesh with each other. One end of one of the rotating shafts is fixedly connected to the output shaft of a drive motor. The drive motor is fixedly connected to the side plate through a mounting block.

[0011] Furthermore, the peeling assembly also includes a cover plate disposed above the peeling roller, the front and rear ends of the cover plate being connected to the upper end of the collection port and the top plate respectively, and the upper end of the side plate near the drive motor being fixedly connected to the feed port.

[0012] Furthermore, the diversion baffle is provided with two chamfers at the end away from the peeling assembly.

[0013] Furthermore, the diversion baffle is located on the plane where the axis of the peeling roller is located, the top plate is higher than the peeling roller in the vertical direction, the bottom plate is lower than the peeling roller in the vertical direction, and the bottom plate is arranged at an angle relative to the horizontal plane.

[0014] Furthermore, the collection port includes an upper baffle, with side baffles fixedly connected to both sides of the upper baffle, and the lower end of the side baffles fixedly connected to a lower baffle, which is inclined relative to the horizontal plane.

[0015] Furthermore, a filter screen is installed on the upper side plate and the top plate near the peeling assembly.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This invention innovatively introduces an air-blowing component. During operation, a fan generates airflow, which, after passing through the ventilation duct, encounters a diversion baffle and is cleverly divided into two paths: one path blows across the upper side of the diversion baffle, effectively blowing the onion skins on the peeling rollers to the collection port and guiding them into the collection box; the other path passes under the diversion baffle and, with the assistance of the base plate, forms an upward-sloping airflow that precisely blows out from the gaps between the peeling rollers, further cleaning the onion skins in the gaps and ensuring they are also smoothly blown into the collection port and finally into the collection box. This design ensures that the peeled onion skins do not remain inside the device, avoiding the tedious manual cleaning process and overcoming the shortcomings of existing technologies.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 An onion peeling device includes two sets of parallel support legs 1, with a support plate 2 fixedly connected to the upper end of the support legs 1. The support plate 2 is provided with a peel collection component 3, a peeling component 4, and an air blowing component 5 arranged sequentially from left to right.

[0028] The skin collection assembly 3 includes a collection port 301, one end of which is fixedly connected to a collection box 302. The bottom end of the collection box 302 is provided with an openable bottom cover 303. Several guide holes 304 are provided on the side wall of the collection box 302. By providing guide holes 304, the air entering the collection box 302 can be better discharged through the guide holes 304.

[0029] The air blowing assembly 5 includes a flow divider 501. Two upper side plates 502 are symmetrically connected to the upper end of the flow divider 501. The upper ends of the upper side plates 502 are fixedly connected to the top plate 503. Two lower side plates 504 are symmetrically connected to the lower end of the flow divider 501. The lower ends of the lower side plates 504 are fixedly connected to the bottom plate 505. Air duct plate a506 is fixedly connected to the same end of the top plate 503 and the bottom plate 505. The same end of the upper side plate 502 and the lower side plate 504 on the same side is fixedly connected to the air duct plate b507. The air duct plate a506 and the air duct plate b507 together form a ventilation duct 508. A fan 509 installed on the support plate 2 is connected to the end of the ventilation duct 508 away from the peeling assembly 4.

[0030] The peeling assembly 4 includes two side plates 401 fixedly connected to the support plate 2. Several peeling rollers 402 are horizontally arranged between the side plates 401. The two ends of the peeling rollers 402 are rotatably connected to the side plates 401 through the rotating shafts 403. A gear 404 is fixedly installed on one of the rotating shafts 403. Adjacent gears 404 mesh with each other. The end of one of the rotating shafts 403 is fixedly connected to the output shaft of the drive motor 405. The drive motor 405 is fixedly connected to the side plate 401 through the mounting block 408.

[0031] The peeling assembly 4 also includes a cover plate 406 disposed above the peeling roller 402. The front and rear ends of the cover plate 406 are connected to the upper end of the collection port 301 and the top plate 503, respectively. The upper end of the side plate 401 near the drive motor 405 is fixedly connected to the feed port 407.

[0032] Among them, the end of the diversion baffle 501 away from the peeling component 4 is provided with two chamfers 5011. By setting two chamfers 5011, the two chamfers 5100 form a triangular shape, which can better divert the air blown out by the fan 509.

[0033] The diversion baffle 501 is located on the plane where the axis of the peeling roller 402 is located. The top plate 503 is higher than the peeling roller 402 in the vertical direction, and the bottom plate 505 is lower than the peeling roller 402 in the vertical direction. The bottom plate 505 is arranged at an angle relative to the horizontal plane.

[0034] It should be noted that the bottom plate 505 is arranged at an angle relative to the horizontal plane to ensure that the air flowing under the diversion baffle 504 can be blown upward at an angle, blowing away the onion skin in the gap between the peeling rollers 402.

[0035] The collection port 301 includes an upper baffle 3011, with side baffles 3012 fixedly connected to both sides of the upper baffle 3011. The lower end of the side baffles 3012 is fixedly connected to a lower baffle 3013, which is inclined relative to the horizontal plane.

[0036] Among them, the upper side plate 502 and the top plate 503 are equipped with a filter screen 6 near the peeling assembly 4 to prevent the onions on the peeling roller 402 from falling onto the diversion baffle 504.

[0037] Working principle: First, start the drive motor 405 and the fan 509. Then, pour the onions to be peeled into the feed inlet 407. The onions will be peeled by the rotating peeling roller 402. At the same time, the air blown by the fan 509 is diverted by the diversion baffle 504 after passing through the ventilation duct 508. Part of the air blows over the upper side of the diversion baffle 501, blowing the onion skins on the peeling rollers into the collection port 301 and then into the collection box 302. The other part of the air flows over the lower side of the diversion baffle 501. Under the action of the bottom plate 505, this part of the air is tilted upward and blown out from the gap between the peeling rollers 402, further blowing the onion skins in the gap between the peeling rollers 402 into the collection port 301, and then into the collection box 30. The peeled onions will roll out from the opposite side of the feed inlet 407 and fall into the pre-placed collection container.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
