Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of garlic processing, and in particular to a gravity sorting machine for peeling garlic. Background Art

[0002] In the agricultural product processing sector, traditional garlic peeling and gravity sorting machines rely primarily on either rotating friction discs or silicone disc extrusion technologies. Rotating friction-based machines utilize friction to forcibly peel the garlic skins. However, this mechanical force can easily damage the garlic cloves' epidermis and tissue, leading to nutrient loss. These damaged cloves are also more susceptible to microbial contamination during subsequent storage and processing. While silicone disc extrusion peeling machines reduce physical damage to the cloves, the uneven contact area and pressure distribution between the discs and the cloves often result in residual skin and incomplete peeling. These residual skins also require additional manual sorting, increasing production costs. Summary of the Invention

[0003] In order to overcome the above defects, the present invention provides a gravity sorting machine for garlic peeling, which solves the technical problems of the existing garlic peeling and sorting technology that easily causes damage to the garlic clove skin, residual garlic skin and incomplete peeling.

[0004] According to one aspect, at least one embodiment of the present invention provides a gravity sorting machine for peeling garlic, comprising: a machine body, wherein a garlic storage box and a garlic skin cavity adjacent to the garlic storage box are disposed within the machine body, the garlic skin cavity having a first opening disposed toward the garlic storage box; and a side opening having a side portion of the garlic storage box capable of communicating with the first opening. A supporting roller assembly includes a first roller body and a second roller body rotatably disposed in the garlic storage box, wherein the first roller body and the second roller body are spaced apart and are used to jointly support the garlic cloves to be peeled; a blowing member, disposed in the garlic storage box and located on a side of the garlic storage box away from the side opening, for blowing the garlic cloves to peel them; The lower edge of the first opening is connected to a guide wall extending obliquely upward into the garlic skin cavity, and the guide wall is used to block the garlic cloves and guide the garlic skins into the garlic skin cavity under the blowing action of the blowing member.

[0005] For example, in a gravity sorting machine for garlic peeling provided by at least one embodiment of the present invention, an inlet is provided above the garlic peel chamber, and the inlet is located on one side of the upper end of the guide wall; The garlic storage box is lifted and arranged in the machine body and can be lifted to the upper end of the first roller body and the second roller body close to the upper end of the guide wall to shorten the height difference from the garlic peels to the inlet.

[0006] For example, in a gravity sorting machine for peeling garlic provided by at least one embodiment of the present invention, the arc of the guide wall bulges toward one side of the garlic storage box.

[0007] For example, in a gravity sorting machine for peeling garlic provided by at least one embodiment of the present invention, a grille is provided on the machine body, and the grille can be lowered between the garlic storage box and the guide wall to block the garlic cloves in the garlic storage box and allow the garlic skins to pass through, or the grille can be raised to no longer block the garlic cloves in the garlic storage box.

[0008] For example, in a gravity sorting machine for peeling garlic provided by at least one embodiment of the present invention, the bottom of the garlic storage box has a bottom opening, so that part of the garlic peels detached from the first roller and the second roller can be removed from the bottom opening; The bottom of the machine body is provided with a collection cavity for storing garlic peels; The machine body is provided with a passage for the garlic storage box to be lifted and lowered, and the passage is used to communicate with the bottom opening and the collecting chamber.

[0009] For example, in a garlic peeling gravity sorting machine provided by at least one embodiment of the present invention, a discharge passage for delivering peeled garlic cloves is further provided at the bottom of the machine body. The discharge passage is located on one side of the channel, and the garlic storage box can be lowered to above the first roller and the second roller to communicate with the discharge passage. A plurality of discharging rollers are rotatably arranged in the discharging passage for supplying garlic cloves.

[0010] For example, in a gravity sorting machine for garlic peeling provided by at least one embodiment of the present invention, the discharge passage is located above the collecting chamber and is connected to the collecting chamber, and the multiple discharge rollers are arranged at intervals so that the garlic peels fall into the collecting chamber through the intervals.

[0011] For example, in a gravity sorting machine for garlic peeling provided by at least one embodiment of the present invention, the second roller is located above one side of the first roller, so that the garlic cloves on the second roller can pass through the first roller to the discharge roller.

[0012] For example, in a gravity sorting machine for peeling garlic provided by at least one embodiment of the present invention, the plurality of discharging rollers are arranged at an angle and gradually decrease in height toward the side away from the garlic storage box.

[0013] For example, in a garlic peeling gravity sorting machine provided by at least one embodiment of the present invention, a screw is rotatably provided on the machine body, the screw is vertically arranged and threadedly connected to the garlic storage box to drive the garlic storage box to rise and fall; A rotary motor is also provided at the bottom of the machine body for driving the screw to rotate.

[0014] The beneficial effects of the embodiments of the present invention are: In this invention, high-speed airflow propels the rollers to rotate (preferably, the blowing element blows tangentially to the first and second rollers, i.e., at least two blowing elements are provided to align the airflow direction with the roller rotation direction). This causes the stacked garlic cloves to tumble on the roller surface, where gravity and friction between the cloves gradually separate the skins from the cloves. The natural tumbling of the cloves by the rollers ensures that each clove has the opportunity to come into contact with the airflow, rollers, and chamber walls, resulting in more uniform peeling. This avoids the direct mechanical forces of traditional friction disks or extrusion methods, reducing skin damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0019] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0020] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0021] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0022] In the description of this embodiment, the terms "up", "down", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figures 1-4As shown, it shows a gravity sorting machine for garlic peeling of the present invention, wherein Figure 1 The whole device after assembling multiple bodies 1 is shown. Figure 2-Figure 4 The internal structure of a single body is shown. In this scheme, Figure 2-Figure 4 As shown, the upper part of the garlic storage box 2 is a feed port, which is used to put the garlic cloves to be peeled and sorted (the garlic cloves here refer to the single garlic cloves after separation) into the garlic storage box 2 through the feed port. One side of the garlic storage box 2 is a side opening 201, and the garlic skin cavity 101 has a first opening 105. The garlic storage box 2 is connected to the garlic skin cavity 101 through the side opening 201 and the first opening 105.

[0025] like Figure 2 As shown, the first roller 301 and the second roller 302 are arranged at intervals in the garlic storage box 2 to form a support surface for supporting the garlic cloves. The blowing member 5 is arranged on the upper part of the garlic storage box 2, as shown in FIG. Figure 1 As shown, an air path connection can be achieved by connecting to the air supply device 11. Preferably, the air path needs to have a certain length to meet the changes in the lifting path of the garlic storage box 2. The blowing member 5 blows from top to bottom at an angle toward the first roller 301 and / or the second roller 302. In this solution, multiple blowing members 5 are shown blowing toward the first roller 301, and they can also blow toward the second roller 302, or toward both the first roller 301 and the second roller 302, without limitation. When the blowing member 5 sprays gas toward the first roller 301 and the second roller 302, the airflow will peel the garlic cloves located on the first roller 301 and the second roller 302. Simultaneously, the high-speed airflow propels the rollers to rotate (preferably, the blowing element 5 is oriented tangentially to the first and second rollers 301, 302; that is, there are at least two blowing elements 5 to ensure that the airflow direction matches the roller rotation direction). This causes the stacked garlic cloves to tumble on the roller surface, gradually separating the skins from the cloves under the influence of gravity and friction between the cloves. The natural tumbling of the cloves by the rollers ensures that each clove has the opportunity to come into contact with the airflow, rollers, and chamber walls, resulting in more uniform peeling. This avoids the direct mechanical forces of traditional friction disks or extrusion methods, reducing the risk of skin damage.

[0026] The gap between the first roller 301 and the second roller 302 needs to be smaller than the size of the garlic cloves to ensure that the first and second rollers 301 and 302 can jointly support the garlic cloves. Furthermore, even if a very small number of small garlic cloves are present, these small cloves can be screened before using the device. For example, a vibrating screen can be used, with the mesh size of the screen set to ensure that the size of the garlic cloves remaining above the screen after screening is larger than the gap between the first roller 301 and the second roller 302. This prevents the garlic cloves from falling into the gap between the first roller 301 and the second roller 302 during use. Furthermore, when installing the first and second rollers 301 and 302, ensure that the gaps between the second roller 302 and the sidewalls of the garlic storage box 2, and between the first roller 301 and the guide wall 103, are smaller than the size of the garlic cloves.

[0027] The garlic peel chamber 101 is used to store shed garlic peels. The lower edge of the first opening 105 is connected to a guide wall 103 that extends upward and slants into the chamber 101. This curved wall 103 gradually rises toward the chamber 101, forming an inclined arched surface. This curved structure prevents garlic peels or cloves from becoming stuck at right angles, improving smoother operation.

[0028] When the blowing element 5 sprays gas, some garlic peels are lifted by the airflow and move upward along the curved surface of the guide wall 103, eventually falling into the garlic peel chamber 101 through the inlet 102. The guide wall 103 prevents the garlic cloves from moving outside the garlic storage box 2, limiting their range of movement and ensuring that they remain above the first roller 301 and the second roller 302 and tumble within the garlic storage box 2.

[0029] Pre-set gaps exist between the first roller 301 and the second roller 302, between the second roller 302 and the sidewall of the garlic storage box 2, and between the first roller 301 and the guide wall 103. During the peeling process, the remaining peeled garlic skins, due to their small size and light weight, can fall through these gaps. In other words, part of the peeled garlic skins are suspended in the airflow, passing through the guide wall 103 and entering the garlic skin chamber 101, while the other part falls through the multiple preset gaps due to gravity, achieving dual-path separation.

[0030] In some examples, such as Figure 2 As shown, the side wall of the garlic peel cavity 101 away from the first opening 105 and the upper edge of the guide wall 103 form an inlet 102. After the garlic peel is blown up by the airflow, it moves upward along the curved surface of the guide wall 103 to the upper end of the guide wall 103, moves toward the inlet 102 due to inertia, and falls downward into the garlic peel cavity 101 above the inlet 102.

[0031] As an embodiment, an exhaust fan (such as a cyclone adsorption device) can be arranged in the garlic peel chamber 101, so that a negative pressure airflow can be formed near the inlet 102, actively sucking in the suspended garlic peels, accelerating their movement into the storage space, and preventing the garlic peels from being retained or falling back into the garlic storage box 2. It can be installed according to actual conditions and is not limited here.

[0032] The garlic storage box 2 is connected to the machine body 1 by a lifting mechanism such as a guide rail and a screw rod and can move up and down. In this solution, a screw rod 9 is used to cooperate with a rotary motor 10 to carry out the lifting and moving of the garlic storage box 2.

[0033] like Figure 2 As shown, in the initial state, the garlic storage box 2 is located at a low position, and the first roller body 301 and the second roller body 302 maintain a certain height difference with the upper end of the guide wall 103, so that the garlic cloves can fully roll on the first roller body 301 and the second roller body 302.

[0034] After peeling for a period of time, the garlic storage box 2 can be raised to a high position. Figure 3 As shown, the upper ends of the first and second rollers 301 and 302 are positioned closer to the upper end of the guide wall 103, shortening the vertical distance between the garlic peels and the inlet 102, or the height difference. This reduced height difference shortens the path for the airflow carrying the garlic peels to the inlet 102, reducing resistance and making it easier for the garlic peels to be blown into the inlet 102. In the high position, some garlic peels accumulated among the cloves are exposed due to the upward position of the rollers, allowing them to be blown away by the secondary airflow. It is important to note that even though the garlic storage box 2 is in the high position, a certain height difference must still be maintained between the upper end surfaces of the first and second rollers 301 and 302 and the upper end surface of the guide wall 103, and the airflow intensity of the blowing element 5 must be reduced. This is primarily to blow the garlic peels into the garlic peel chamber 101. Maintaining this certain height difference prevents the cloves from being simultaneously blown into the chamber 101. If any garlic peels remain after a single lift, the process of lowering, re-peeling, and lifting can be repeated, enhancing the peeling effect through multi-stage processing.

[0035] In traditional fixed-height structures, garlic peels can be buried due to gravity or clove stacking, making them difficult to separate effectively with airflow. The lifting mechanism dynamically adjusts height to proactively reduce the time the garlic peels spend in the peeling area. This allows for separation without the need for continuous high-power airflow. Mechanical position adjustment reduces reliance on air pressure, minimizing energy consumption while maintaining optimal results.

[0036] At the same time, when the garlic storage box 2 is in a low position, it focuses on achieving the initial peeling of the garlic skins through the rolling of the rollers and the impact of the airflow; when it is in a high position, it focuses on achieving the complete collection of the garlic skins by shortening the separation path and enhancing the adsorption efficiency, forming a staged operation of peeling and collection, effectively reducing the defect of incomplete one-time separation in the traditional static structure.

[0037] In some examples, such as Figure 2-Figure 4As shown, the guide wall 103 is generally arc-shaped, with the center of the arc located outside the garlic storage box 2. Therefore, the arc protrudes toward the garlic storage box 2. The lower end of the guide wall 103, near the end of the garlic storage box 2, is tangentially oriented toward a vertical line, resulting in a steep lower end that closely adheres to the edge of the garlic storage box 2. This directly blocks the garlic cloves from moving outside the garlic storage box 2 (toward the garlic peel chamber 101). Even if the rotation of the roller causes the garlic cloves to tumble, the relatively vertical lower arc wall physically blocks them and forces them back into the garlic storage box 2, preventing them from escaping the peeling area due to inertia or airflow.

[0038] The upper end of the guide wall 103, on the side away from the garlic storage box 2, is tangentially horizontal, making the upper end of the curved wall gently flattened and extending toward the entrance 102 of the garlic peel chamber 101. The horizontal tangential curved surface causes the movement trajectory of the garlic peels to gradually become horizontal, eventually causing them to fall toward the entrance 102 (away from the garlic storage box 2) rather than flying vertically upward.

[0039] If the guide wall 103 is concavely curved (with its center facing the inside of the garlic storage box 2), the lower tangent line tends to be horizontal, while the upper tangent line tends to be vertical. This prevents the lower end from effectively shielding the garlic cloves. Furthermore, the garlic peels will be directed vertically upwards as they move along the concave curved surface, where they can easily fall back due to turbulent airflow or fail to properly enter the inlet 102. A convex structure, on the other hand, ensures that the garlic peels move along a predetermined path through horizontal guidance, improving separation reliability. Furthermore, the smooth curved surface of the convex curved wall lacks right angles, allowing both the garlic peels and cloves to slide smoothly along the wall, reducing the risk of material jamming due to sharp corners (traditional right-angled walls are prone to accumulation of damp garlic peels, causing blockage).

[0040] In some examples, such as Figure 2-Figure 3 As shown, a grille 6 is provided on the machine body 1. Its function is to ensure that when the garlic storage bin 2 is in the lowered position for peeling, the gap between the first roller 301 and the guide wall 103 is small, smaller than the size of the garlic cloves, making it difficult for the cloves to fall through the gap. At this time, the grille 6 is lifted by a linear drive 7 (e.g., a cylinder), removing most of the obstruction from the garlic storage bin 2 and allowing the garlic peels to pass through the guide wall 103 and into the garlic peel chamber 101 more easily.

[0041] As the garlic storage box 2 rises, the gap between the first roller 301 and the guide wall 103 gradually increases due to the curved structure of the guide wall 103. To prevent garlic cloves from falling through this gap, the grille 6 is simultaneously driven downward, positioned to one side of the first roller 301. This shields the garlic storage box 2, preventing the cloves from escaping and ensuring stable peeling. The interior of the garlic storage box 2 is now connected to the inlet 102 through the opening of the grille 6, preventing the cloves from falling while maintaining normal peeling.

[0042] In some examples, a bottom opening 202 is provided at the bottom of the garlic storage box 2, which is located below the first roller body 301 and the second roller body 302. When the garlic cloves roll and peel on the surface of the roller body, the peeled garlic skins can fall through the gaps between the first roller body 301 and the second roller body 302, between the second roller body 302 and the side wall of the garlic storage box 2, and between the first roller body 301 and the guide wall 103 due to their small size and light weight, and are discharged from the garlic storage box 2 through the bottom opening 202.

[0043] During the raising and lowering of the garlic storage box 2, the bottom opening 202 remains open downward. This opening directly connects to the collection chamber 104 at the bottom of the housing 1, allowing the garlic peels to freely fall into the collection chamber 104 for centralized collection. Furthermore, the bottom opening 202 reduces residue within the garlic storage box 2, preventing accumulation of damp garlic peels that can cause adhesion or mildew, thereby improving the hygiene of the equipment.

[0044] In summary, some garlic peels can move through multiple gaps (refer to the preset gaps described above) to the bottom opening 202 and fall into the collection chamber 104. Others can pass through the guide wall 103 to the garlic peel chamber 101. One movement path is located above the garlic cloves, and the other is located below the garlic cloves. Both paths simultaneously serve to remove the garlic peels, effectively improving peeling efficiency compared to traditional single-path separation. As an alternative, a drawer-like structure can be provided at the bottom of the collection chamber 104 to facilitate regular cleaning of the garlic peels, although this is not a limitation here.

[0045] In some examples, such as Figure 4 As shown, the bottom of the machine body 1 is also provided with a discharge port 106. After the garlic storage box 2 is lowered, it can be located on one side of the multiple discharge rollers 8, so that the upper part of the first roller body 301 and the second roller body 302 is connected to the upper part of the discharge roller 8 in the discharge port 106. The garlic cloves on the first roller body 301 and the second roller body 302 fall onto the discharge roller 8 under the action of air blowing and roller rotation, and move toward the discharge port 106. As a preferred embodiment, Figure 5 As shown, the second roller body 302 is located above one side of the first roller body 301, forming a height difference, so that the garlic cloves can roll from the surface of the second roller body 302 to the first roller body 301 during the peeling process, and then be transported to the entrance of the discharge port 106 through the first roller body 301, ensuring the continuity of the material flow direction.

[0046] Among them, Figure 4 As shown, the height of the multiple discharge rollers 8 gradually decreases (forming a certain slope) toward the side away from the garlic storage box 2. After the garlic cloves fall on the discharge rollers 8, they will naturally roll to one side under the action of gravity. There is a gap between the discharge rollers 8. Preferably, the gap is smaller than the diameter of the garlic cloves but larger than the size of the garlic peels. As the garlic cloves move on the roller surface, a small amount of garlic peels mixed in with them fall through the gap due to their own weight into the collection chamber 104 below. This design achieves three-step impurity removal during the garlic clove discharge process, ensuring the purity of the discharge.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
