TECHNICAL FIELD
[0001] The embodiment of the present application relates to fruit and vegetable sorting technical field, and particularly relates to a receiving structure, a fruit and vegetable loading device, a fruit and vegetable conveying device and a fruit and vegetable framing device. BACKGROUND
[0002] In the processing or sorting process of fruits and vegetables (such as grapes, blueberries, etc.), the fruits and vegetables need to be transferred by a conveying device. However, in the prior art, when the fruits and vegetables fall from a high place to the receiving surface of the receiving structure, the fruits and vegetables are prone to roll on the receiving surface, resulting in frequent contact and friction between each part of the surface of the fruits and vegetables and the surface of the receiving surface.
[0003] At present, the receiving structure commonly used in fruit and vegetable processing or sorting equipment is generally a rigid member or a leather material, which is either relatively rough on the surface or easily adheres to fruit powder, so that the fruit powder retention rate is not good after the fruits and vegetables roll on the receiving surface. CONTENT OF THE UTILITY MODEL
[0004] An object of the embodiment of the present application is to provide a receiving structure, a fruit and vegetable loading device, a fruit and vegetable conveying device and a fruit and vegetable framing device to solve the technical problem of poor fruit powder retention rate of fruits and vegetables after passing through the receiving structure of the fruit and vegetable processing or sorting equipment in the related technical content.
[0005] In a first aspect, the embodiment of the present application provides a receiving structure, comprising a receiving surface, wherein the receiving surface is provided with a fruit powder retention film for contacting fruits and vegetables and repelling fruit powder, and the receiving structure is used for receiving falling fruits and vegetables and can allow the fruits and vegetables to roll on the receiving surface.
[0006] Through the above structure, the receiving surface forms a low-adhesion contact interface through the fruit powder retention film arranged on the surface, the film repels fruit powder, and the adhesion between the film and the surface of the fruits and vegetables can be reduced. When the fruits and vegetables fall from a high place to the receiving surface, the repelling property of the film can effectively retain the fruit powder on the surface of the fruit skin during the rolling process due to the small frictional resistance, and the fruit powder will not be adsorbed or scraped off by the film. Compared with the traditional rigid or leather receiving surface, the fruit powder retention rate can be effectively improved.
[0007] Optionally, the fruit powder retention film is a PET polyester film.
[0008] Through the above structure, the PET polyester film has high surface smoothness and low surface energy characteristics, and its molecular structure is stable and not prone to chemical adsorption with sugar, lipids and other components in the fruit powder. When the fruits and vegetables roll, the surface of the PET film reduces the contact area with the fruit powder through physical repelling, and its moderately rigid property can buffer the impact of the falling fruits and vegetables, avoiding the additional loss of fruit powder caused by the damage of the fruit skin.
[0009] Optionally, the thickness of the fruit powder retention film is 0.1mm-1mm.
[0010] Through the above structure, the film thickness is designed to be 0.1mm~1mm, and by optimizing the mechanical properties of the material, it is ensured that the thickness interval has sufficient rigidity to resist deformation of the fruit and vegetable impact and also retains moderate flexibility to avoid brittle fracture.
[0011] Optionally, a PVC substrate is arranged between the receiving surface and the fruit powder retaining film.
[0012] Through the above structure, the PVC substrate is arranged as an intermediate layer between the receiving surface substrate and the fruit powder retaining film, which has stable chemical properties and high elastic modulus, can provide physical support at the same time, and the fruit powder retaining film can be closely attached to the PVC substrate relative to the receiving structure of the rigid member. The PVC substrate absorbs and disperses the impact force when the fruit and vegetable falls, reduces the local stress concentration of the fruit powder retaining film, and prevents the film from tearing.
[0013] In a second aspect, the embodiments of the present application provide a fruit and vegetable loading device, which comprises a hopper, the hopper comprises a hopper frame and a baffle, the hopper is provided with a hopper bin and a feeding port and a discharging port respectively communicating with the hopper bin, and the baffle is detachably mounted on the hopper frame and encloses the hopper bin, the feeding port and the discharging port with the hopper frame to form the hopper.
[0014] The hopper frame is in the shape of a shovel, and the hopper frame comprises the receiving structure and side plates located on both sides of the receiving structure, and the receiving structure is an obliquely arranged plate-shaped structural member.
[0015] Through the above structure, the fruit and vegetable sliding track or flow guide surface of the hopper is integrated with the receiving structure, and the fruit powder retaining film covers the inner wall or the outlet transition area of the hopper to form a continuous low-adhesion conveying interface. When the fruit and vegetable enters the conveying device from the hopper, it rolls or slides along the surface of the fruit powder retaining film, and the repelling property of the fruit powder retaining film reduces the shedding of fruit powder caused by friction or collision.
[0016] In a third aspect, the embodiments of the present application provide a fruit and vegetable conveying device, which comprises:
[0017] A first conveying assembly for conveying fruit and vegetable in a first direction;
[0018] A second conveying assembly, the height of the second conveying assembly is lower than the height of the first conveying assembly, and the second conveying assembly is used for conveying fruit and vegetable in a second direction;
[0019] The receiving structure as claimed in any one of the above, the receiving structure is arranged between the first conveying assembly and the second conveying assembly, and the receiving structure is used for receiving the fruit and vegetable output by the first conveying assembly to the second conveying assembly.
[0020] Through the above structure, the fruit and vegetable conveying device provided by the embodiment of the application is characterized in that the receiving structure is arranged at the height difference transition area between the first conveying assembly and the second conveying assembly, the inclination angle of the receiving structure is matched with the spatial layout of the two conveying assemblies, and a continuous fruit and vegetable conveying path is formed. The fruit powder retention film of the receiving structure covers the surface layer of the receiving surface, and the low adhesion characteristic of the fruit powder retention film causes the fruit powder on the surface of the fruit and vegetable to be only affected by the weight and inertial force during rolling, and additional friction loss caused by adhesion of the contact surface is avoided.
[0021] Optionally, the first direction and the second direction are parallel and in the same direction, the first conveying assembly comprises a planar conveying belt, and the second conveying assembly comprises a V-shaped structure belt.
[0022] The receiving structure comprises oppositely arranged first and second connecting portions, the first connecting portion is arranged at the output end of the planar conveying belt, the first connecting portion is arranged along the width direction of the planar conveying belt, the second connecting portion is arranged at the input end of the V-shaped structure belt, the edge of the second connecting portion is matched with the cross-sectional shape of the V-shaped structure belt and extends into the V-shaped structure belt, and the fruit powder retention film comprises oppositely arranged first and second edges, the first edge is arranged in alignment with the edge of the first connecting portion, and the second edge is arranged in alignment with the edge of the second connecting portion.
[0023] Through the above structure, when the fruit and vegetable is transferred from the planar conveying belt to the V-shaped structure belt, the fruit and vegetable will be arranged in a row on the V-shaped structure belt. The planar conveying belt and the V-shaped structure belt are smoothly connected through the first and second connecting portions, the first connecting portion extends along the width direction of the planar conveying belt to form a flow guide platform, and the second connecting portion is matched with the shape of the input end of the V-shaped structure belt, and the edge of the second connecting portion extends into the V-shaped structure belt to form a V-shaped entrance guide surface.
[0024] Optionally, the fruit and vegetable conveying device further comprises a blowing mechanism, the blowing mechanism is arranged on one side of the first direction of the first conveying assembly, the blowing mechanism is used for laterally blowing off the fruit and vegetable on the first conveying assembly, and the receiving structure is arranged on the other side of the first direction of the first conveying assembly, and the receiving structure can receive the fruit and vegetable blown off laterally by the blowing mechanism.
[0025] Through the above structure, the blowing mechanism intervenes in the motion track of the fruit and vegetable on the fruit cup conveying belt through a lateral air flow, the fruit and vegetable is separated from the fruit cup after being impacted by the air flow and falls along a parabolic path under the action of inertia. The receiving structure is located on the opposite side of the blowing mechanism, the fruit powder retention film of the receiving structure forms a low-resistance rolling interface, and the fruit and vegetable rolls along the inclined or arc-shaped receiving surface to the second conveying assembly after contacting the fruit powder retention film. The repelling characteristic of the fruit powder retention film causes the fruit powder on the surface of the fruit and vegetable to be only affected by a weak shearing force during rolling, and fruit powder peeling caused by adhesion or friction of the interface is avoided.
[0026] Optionally, the receiving structure is a flexible structure, and the receiving structure is arranged to overhang above the second conveying assembly.
[0027] Through the above structure, the overhanging design of the flexible structure deforms when the fruits and vegetables fall, and the impact kinetic energy is absorbed by the elastic deformation of the material itself, reducing the instantaneous impact force between the fruits and vegetables and the receiving surface. The fruit powder retention film covers the surface of the flexible structure, forming a continuous low-adhesion rolling path. After the fruits and vegetables contact the fruit powder retention film, they naturally roll along the curvature of the overhanging structure. The low-adhesion property of the surface of the fruit powder retention film reduces the probability of the fruit powder being scraped or adhered.
[0028] In a fourth aspect, the embodiments of the present application also provide a fruit and vegetable boxing device, comprising:
[0029] a third conveying assembly for conveying fruits and vegetables;
[0030] a fruit box for receiving fruits and vegetables;
[0031] The receiving structure as claimed in any one of the above, the receiving structure is arranged at the output end of the third conveying assembly, the fruit box is arranged below the receiving structure, and the receiving structure is used to receive the fruits and vegetables output by the third conveying assembly to the fruit box.
[0032] Through the above structure, the receiving structure is arranged between the output end of the third conveying assembly and the fruit box, and the fruit powder retention film covers the surface thereof to form a continuous rolling path. After the fruits and vegetables slide from the end of the third conveying assembly, they roll downward along the surface of the film to the fruit box due to gravity. The low-adhesion property of the film causes only slight friction when the fruits and vegetables roll, and the fruit powder is not easily separated from the surface of the fruits and vegetables due to the low-adhesion interface. Exemplarily, the third conveying assembly can adopt a planar conveying belt, and the fruits and vegetables output by the third conveying assembly roll on the fruit powder protection film of the receiving structure to the low-positioned fruit box, thereby completing the boxing of the fruits and vegetables.
[0033] The embodiments of the present application can achieve the following technical effects: The receiving surface forms a low-adhesion contact interface through the fruit powder retention film arranged on the surface, the film is low-adhesion to fruit powder, and the adhesion between the film and the surface of the fruits and vegetables can be reduced. When the fruits and vegetables fall from a high position to the receiving surface, the low-adhesion property of the film effectively retains the fruit powder on the surface of the fruits and vegetables due to the small frictional resistance during rolling, and the fruit powder is not easily adsorbed or scraped off by the film. Compared with the traditional rigid or leather receiving surface, the fruit powder retention rate can be effectively improved. BRIEF DESCRIPTION OF DRAWINGS

[0044] In order to facilitate the understanding of the present application, the present application will be described in more detail below in combination with the drawings and specific embodiments. It should be noted that when an element is described as being "connected" to another element, it can be directly on the other element or one or more intervening elements can be present therebetween.

In addition, the terms "first", "second", etc. are only for the purpose of description and cannot be understood as indicating or implying relative importance.
[0045] Unless otherwise defined, all technical and scientific terms used in the present disclosure are intended to have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.
[0046] In the processing or sorting process of fruits and vegetables (such as grapes, blueberries, etc.), the fruits and vegetables need to be transported by a conveying device. The conveying device of the processing or sorting equipment is configured with a receiving structure for receiving fruits and vegetables at a conveying position with a height difference. When the fruits and vegetables fall from a high place, they will roll on the receiving surface of the receiving structure.
[0047] In the related art, the receiving structure commonly used in fruit and vegetable processing or sorting equipment is generally a rigid member or a leather material. Either the surface is relatively rough, or it is easy to stick fruit powder, so that the fruit powder retention rate is not good after the fruit and vegetable rolls on the receiving surface.
[0048] To solve the above technical problems, in a first aspect, the present application provides a receiving structure, which can be applied to fruit and vegetable processing equipment, fruit and vegetable sorting equipment, and specifically applied to the fruit and vegetable feeding device, fruit and vegetable conveying device, or fruit and vegetable frame loading device of any of the fruit and vegetable processing equipment and fruit and vegetable sorting equipment. Wherein, the fruits and vegetables can be fruits such as blueberries and grapes with fruit powder, or melons such as winter melon with fruit frost.
[0049] Please refer to Figure 1 In some embodiments, the receiving structure 10 includes a receiving surface provided with a fruit powder retention film 11 for contacting fruits and vegetables and repelling fruit powder. The receiving structure 10 is used to receive falling fruits and vegetables and can allow the fruits and vegetables to roll on the receiving surface.
[0050] The structural principle of the receiving structure 10 of the present application is that the receiving surface forms a low-adhesion contact interface through the fruit powder retention film 11 provided on the surface. The film repels fruit powder and can reduce the adhesion between the fruit skin and the film. When the fruits and vegetables fall from a high place to the receiving surface, the repelling property of the film effectively retains the fruit powder on the fruit skin surface due to the small frictional resistance during rolling, and the fruit powder will not be adsorbed or scraped off by the film.
[0051] It can be understood that the receiving structure 10 of the present application can effectively improve the fruit powder retention rate compared to the traditional rigid or leather receiving surface.
[0052] In some embodiments, the fruit powder retention film 11 is a PET (polyethylene terephthalate) polyester film, specifically a food-grade PET polyester film.
[0053] It can be understood that the PET polyester film has high surface smoothness and low surface energy characteristics, and its molecular structure is stable and not easy to chemically adsorb with sugar, lipid and other components in the fruit powder. When the fruits and vegetables roll, the surface of the PET film reduces the contact area with the fruit powder through physical repulsion, and its moderate rigidity can buffer the impact of the falling fruits and vegetables, avoiding the additional loss of fruit powder caused by the damage of the fruit skin.
[0054] In some embodiments, a food-grade Teflon film can also be used, which has extremely low surface energy and small friction coefficient, and also has super-hydrophobic and oleophobic properties, which can reduce the adhesion of fruit powder. In other embodiments, other films with small friction and not easy to adhere to fruit powder can also be used, which are not limited here.
[0055] In some embodiments, the thickness of the fruit powder retention film 11 is 0.1mm-1mm.
[0056] It can be understood that the film thickness is designed to be 0.1mm-1mm, which optimizes the mechanical properties of the material to ensure that the thickness range has sufficient rigidity to resist the impact deformation of fruits and vegetables, and also retains moderate flexibility to avoid brittle fracture.
[0057] In some embodiments, the thickness range is adapted to the needs of different transportation scenarios, for example, thinner fruit powder retention film 11 is suitable for low-drop scenarios of light fruits and vegetables, and thicker fruit powder retention film 11 can cope with the impact of high-drop or large-mass fruits and vegetables, which overall improves the fruit powder retention effect, while taking into account the durability and economy of the film.
[0058] For example, when the fruit powder retention film 11 is set on a rigid piece, a 1mm fruit powder retention film 11 can be selected, which can provide a certain buffer for the rolling of fruits and vegetables compared to the rigid piece fruit powder retention film 11, thereby protecting the fruits and vegetables. For another example, when the fruit powder retention film 11 is set on a leather flexible piece, a 0.1mm fruit powder retention film 11 can be selected, which can better adhere the fruit powder retention film 11 to the leather flexible piece.
[0059] In other embodiments, the designer can set the thickness of the fruit powder retention film 11 according to actual experience, and the thickness range is not limited to 0.1mm-1mm, which is not limited here.
[0060] Please refer to Figure 2 In some embodiments, a PVC (polyvinyl chloride) substrate is provided between the receiving surface and the fruit powder retention film 11, which is a food-grade PVC substrate 12.
[0061] It can be understood that the PVC substrate 12 is arranged as an intermediate layer between the receiving surface base material and the fruit powder retention film 11, which is chemically stable and has a high elastic modulus, can provide physical support at the same time, and the fruit powder retention film 11 can be more closely attached to the PVC substrate 12 relative to the receiving structure 10 of the rigid member. The PVC substrate 12 reduces the local stress concentration of the fruit powder retention film 11 by absorbing and dispersing the impact force when the fruits and vegetables fall, preventing the film from tearing.
[0062] Please refer to Figure 3 In a second aspect, the embodiments of the present application provide a fruit and vegetable loading device 100, which comprises a hopper 20, and the hopper 20 comprises the receiving structure 10 of the above-mentioned embodiments.
[0063] It can be understood that the fruit and vegetable chute or flow guide surface of the hopper 20 is integrated with the receiving structure 10, and the fruit powder retention film 11 covers the inner wall or the outlet transition area of the hopper 20, forming a continuous low-adhesion conveying interface. When the fruits and vegetables enter the conveying device from the hopper 20, they roll or slide along the surface of the fruit powder retention film 11, and the repelling characteristics of the fruit powder retention film 11 reduce the shedding of fruit powder caused by friction or collision.
[0064] In some embodiments, the loading device comprises a hopper 20, and the hopper 20 comprises a hopper frame 21 and a baffle 22. The hopper 20 is further provided with a hopper compartment 23, and a feeding port and a discharging port respectively communicating with the hopper compartment 23. The baffle 22 is detachably mounted on the hopper frame 21 and encloses the hopper compartment 23, the feeding port and the discharging port of the hopper 20 with the hopper frame 21. The hopper frame 21 is shovel-shaped, and comprises a receiving structure 10 and side plates 211 located on both sides of the receiving structure 10. The receiving structure 10 is an inclined plate structure. In addition to the receiving structure 10, the inner walls of the side plates 211 and the baffle 22 can be provided with a fruit powder retention film 11 to improve the fruit powder retention rate after the fruits and vegetables are rolled in contact.
[0065] Please refer to Figure 4 In a third aspect, the embodiments of the present application provide a fruit and vegetable conveying device 200, which comprises a first conveying assembly 30, a second conveying assembly 40, and the receiving structure 10 of the above-mentioned embodiments. The first conveying assembly 30 is used for conveying fruits and vegetables in a first direction. The height of the second conveying assembly 40 is lower than the height of the first conveying assembly 30, and the second conveying assembly 40 is used for conveying fruits and vegetables in a second direction. The receiving structure 10 is arranged between the first conveying assembly 30 and the second conveying assembly 40, and the receiving structure 10 is used for receiving the fruits and vegetables output by the first conveying assembly 30 to the second conveying assembly 40.
[0066] It can be understood that the fruit and vegetable conveying device 200 provided by the embodiment of the application is arranged at the height difference transition area between the first conveying assembly 30 and the second conveying assembly 40, the inclination angle of the receiving structure 10 is matched with the spatial layout of the two conveying assemblies, and a continuous fruit and vegetable conveying path is formed. The fruit powder retention film 11 of the receiving structure 10 covers the surface layer of the receiving surface, and the low adhesion characteristic of the fruit powder retention film 11 causes the fruit powder on the fruit and vegetable to be only subjected to the action of the weight and the inertial force in the rolling process, and the fruit and vegetable will not be subjected to additional friction loss caused by adhesion of the contact surface.
[0067] Please refer to Figure 5 In some embodiments, the first direction and the second direction are parallel and in the same direction, the first conveying assembly 30 includes a flat conveying belt, and the second conveying assembly 40 includes a V-shaped structure belt. The receiving structure 10 includes oppositely arranged first and second connecting portions 13 and 14, the first connecting portion 13 is arranged at the output end of the flat conveying belt, the first connecting portion 13 is arranged along the width direction of the flat conveying belt, the second connecting portion 14 is arranged at the input end of the V-shaped structure belt, the edge of the second connecting portion 14 is adapted to the cross-sectional shape of the V-shaped structure belt and extends into the V-shaped structure belt, and the fruit powder retention film 11 includes oppositely arranged first and second edges, the first edge is arranged in alignment with the edge of the first connecting portion 13, and the second edge is arranged in alignment with the edge of the second connecting portion 14.
[0068] It can be understood that when the fruit and vegetable is transferred from the flat conveying belt to the V-shaped structure belt, the fruit and vegetable will be arranged in a column on the V-shaped structure belt. The V-shaped structure belt can be arranged in the width direction of the flat conveying belt to form multiple channels, so that the fruit and vegetable on the flat conveying belt can be arranged in multiple columns on different V-shaped structure belts to transport the multiple columns of fruit and vegetable. The flat conveying belt and the V-shaped structure belt are smoothly connected through the first and second connecting portions 13 and 14, the first connecting portion 13 extends along the width direction of the flat conveying belt to form a flow guide platform, and the second connecting portion 14 is matched with the shape of the input end of the V-shaped structure belt, and the edge of the second connecting portion 14 extends into the V-shaped structure belt to form a V-shaped inlet guide surface.
[0069] Please refer to Figure 6 In some embodiments, the fruit and vegetable conveying device 200 further includes a blowing mechanism 50 arranged at one side of the first direction of the first conveying assembly 30, the blowing mechanism 50 is used for laterally blowing off the fruit and vegetable on the first conveying assembly 30, and the receiving structure 10 is arranged at the other side of the first direction of the first conveying assembly 30, and the receiving structure 10 can receive the fruit and vegetable blown off by the blowing mechanism 50.
[0070] It can be understood that the air blowing mechanism 50 intervenes in the motion trajectory of the fruits and vegetables on the fruit cup conveying belt through a lateral air flow, and the fruits and vegetables are separated from the fruit cup after being impacted by the air flow and fall along a parabolic path under the action of inertia. The receiving structure 10 is located on the opposite side of the air blowing mechanism 50, and the fruit powder retention film 11 on the surface of the receiving structure 10 forms a low-resistance rolling interface. After the fruits and vegetables contact the film, they roll down along the inclined or arc-shaped receiving surface to the second conveying assembly 40 due to the action of gravity. The fruit powder retention film 11 has a repelling property, so that the fruit powder on the surface of the fruits and vegetables is only subjected to a weak shearing force during rolling, avoiding the fruit powder from being peeled off due to interfacial adhesion or friction.
[0071] Exemplarily, the first conveying assembly 30 includes a driving mechanism, a chain transmission mechanism, and a fruit cup. The driving mechanism is connected to and drives the chain transmission mechanism, and the fruit cup is arranged on the chain of the chain transmission mechanism. The driving mechanism can drive the fruit cup to run by driving the chain of the chain transmission mechanism. The fruit cup conveying belt includes a plurality of fruit cups connected in sequence, and each fruit cup carries at least one corresponding fruit and vegetable. The driving mechanism can select a corresponding motor according to actual needs. The air blowing mechanism 50 includes a jet nozzle, an air path, and an air source. The jet nozzle is connected to the air path, and the air path is connected to the air source. The air source supplies air to the jet nozzle through the air path, so that the jet nozzle blows the fruits and vegetables on the fruit cup laterally. The fruits and vegetables are caught by the receiving structure 10 and roll down along the receiving surface to the second conveying assembly 40. The designer can set the specific forms of the jet nozzle, the air path, and the air source according to actual experience, which is not limited here.
[0072] In some embodiments, the receiving structure 10 is a flexible structure, and the receiving structure 10 is suspended above the second conveying assembly 40.
[0073] It can be understood that the suspension design of the flexible structure causes it to deform when the fruits and vegetables fall, and the impact kinetic energy is absorbed by the elastic deformation of the material itself, reducing the instantaneous impact force between the fruits and vegetables and the receiving surface. The fruit powder retention film 11 covers the surface of the flexible structure, forming a continuous low-adhesion rolling path. After the fruits and vegetables contact the fruit powder retention film 11, they naturally roll down along the arc of the suspended structure. The repelling property of the surface of the fruit powder retention film 11 reduces the probability of fruit powder being scraped or adhered.
[0074] Exemplarily, the receiving structure 10 is a flexible sheet-shaped PVC structural member provided with a fruit powder protection film. When the fruits and vegetables are blown off by the air blowing mechanism 50, the receiving structure 10 can receive the fruits and vegetables and absorb the impact force of the fruits and vegetables due to its own suspension and softness, thereby protecting the fruits and vegetables. The fruits and vegetables roll down on the fruit powder protection film to the second conveying assembly 40, and are transferred by the second conveying assembly 40, wherein the second conveying assembly 40 can adopt a planar conveying belt.
[0075] Please refer to Figure 7In the fourth aspect, the embodiments of the present application also provide a fruit and vegetable boxing device 300, comprising a third conveying assembly 60, a fruit box 70 and the receiving structure 10 described above. The third conveying assembly 60 is used for conveying fruits and vegetables, and the fruit box 70 is used for receiving fruits and vegetables. The receiving structure 10 is arranged at the output end of the conveying assembly, and the fruit box 70 is arranged below the receiving structure 10. The receiving structure 10 is used for receiving the fruits and vegetables output by the third conveying assembly 60 into the fruit box 70.
[0076] It can be understood that the receiving structure 10 is arranged obliquely between the output end of the third conveying assembly 60 and the fruit box 70, and the fruit powder retaining film 11 covers the surface thereof to form a continuous rolling path. After the fruits and vegetables slide off the end of the third conveying assembly 60, they roll downward along the surface of the film under the action of gravity and into the fruit box 70. The fruit powder is not easy to separate from the surface of the fruits and vegetables due to the low adhesion interface effect caused by the slight friction of the fruits and vegetables when rolling due to the repelling property of the film. Exemplarily, the third conveying assembly 60 can adopt a planar conveying belt. The fruits and vegetables output by the third conveying assembly 60 roll on the fruit powder protection film of the receiving structure 10 to the low-positioned fruit box 70, thereby completing the boxing of the fruits and vegetables.
[0077] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above. In order to be brief, they are not provided in details; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
