Description

Technical Field

[0001] The present invention relates to the field of vegetable washing machines, and in particular to a vibration dehydration and conveying device for vegetable washing machines. Background Art

[0002] Among household kitchen appliances, the application of vegetable washing machines and vibrating dehydration and conveying devices is gradually becoming popular. Among them, dehydration treatment is a crucial link. It not only prolongs the shelf life of vegetables, but also greatly facilitates the transportation and storage of vegetables, meeting the market demand for long-term supply of vegetables.

[0003] Different types of vegetables vary greatly in terms of water content, shape, size, texture, etc., and their tolerance to vibration force and dehydration requirements are also different. Even the same vegetables have different degrees of maturity and freshness, and their reactions to vibration force are also different. Therefore, it is difficult to accurately control the vibration force of existing household kitchen appliances during use.

[0004] If the vibration force is too large, it will produce a large impact force, and the more fragile vegetables may have scratches and indentations on the surface, or even cause damage to the internal tissues; if the vibration force is reduced, although the damage rate of the vegetables can be reduced, it will lead to incomplete dehydration and the need to extend the dehydration time, which not only increases energy consumption, but may also cause the loss of nutrients in the vegetables and deteriorate the taste due to long-term vibration. It can be seen that the existing household kitchen appliance dehydration equipment still has a lot of room for improvement. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0030] like Figures 1 to 8 The vibrating dehydration conveying device for a vegetable washing machine shown in the figure comprises a washing machine 1 and a conveyor 2. The discharge position of the washing machine 1 is connected to the feed position of the conveyor 2. The conveyor 2 has a conveyor belt 3 and further comprises: The air drying unit 4 includes a plurality of air drying units 4, which are fixed on the top surface of the conveyor 2 at equal intervals; The support frame includes a connecting bar 5 and a moving bar 6. The connecting bar 5 is arranged on the top surface of the conveyor mesh belt 3 and is located in the front side of the conveying direction. The moving bar 6 is arranged on the top surface of the conveyor mesh belt 3 and is located in the rear side of the conveying direction. Two first support airbags 7 are fixed between the connecting bar 5 and the moving bar 6. The connecting bar 5 is rotatably connected to the conveyor mesh belt 3. A vibration motor 8 is fixed on the surface of the moving bar 6, and an electric push rod 9 is embedded and fixed on the bottom surface of the moving bar 6. The support plate 10 is made of a flexible material and is fixed between the two first support airbags 7 . A plurality of water-permeable holes 11 are provided on the surface of the support plate 10 .

[0031] Specifically, the air drying unit 4 is composed of a plurality of fans 401, which are fixed on a support frame 402, and the support frame 402 is fixed on the housing of the conveyor 2. After the leaves are washed by the washing machine 1, the washing machine 1 discharges the leaves to the conveyor 2. In order to ensure that the leaves are evenly dispersed on the conveyor 2, a dedicated leaf dispersing device can be used for dispersion. This is a prior art and will not be described in detail here. After the vegetable leaves enter the conveyor 2, they are supported by the support plate 10. The support plate 10 is provided with a water-permeable hole 11. The free water on the surface of the vegetable leaves can pass through the water-permeable hole 11 and the conveyor belt 3 and then be discharged. The drained water can be recycled and reused, which is conducive to saving water resources. Different types of vegetables vary greatly in terms of water content, shape, size, texture, etc., and their tolerance to vibration force and dehydration requirements are also different. Even for the same vegetable, its maturity and freshness are different, and its response to vibration force is also different. If the vibration force is too large, it will produce a large impact force. The more fragile vegetables may have scratches and indentations on the surface, and even cause damage to the internal tissue. If the vibration force is reduced, although the damage rate of the vegetables can be reduced, it will lead to incomplete dehydration and the need to extend the dehydration time. This not only increases energy consumption, but may also cause the loss of nutrients in the vegetables and deteriorate the taste due to long-term vibration. The present invention can solve the above problems. The specific working method is as follows: in the process of transporting the vegetable leaves, the air drying unit 4 works synchronously to blow and dry the surface of the vegetable leaves. In the process of the support frame moving to the blowing port position, since the electric push rod 9 is embedded and fixed on the bottom surface of the moving bar 6, the bottom of the electric push rod 9 has a push piece. By starting the electric push rod The movable end of the rod 9 and the electric push rod 9 can push the top moving piece out, and the bottom of the top moving piece contacts the conveyor mesh belt 3. As the electric push rod 9 extends, the distance between the movable plate 6 and the conveyor mesh belt 3 gradually increases, and the connecting strip 5 at the other end of the support frame is rotatably connected to the conveyor mesh belt 3, so that the support frame and the support plate 10 are flipped to an inclined state. After the vegetable leaves are driven to form an inclined state by the support plate 10, the vibration motor 8 is started to drive the support frame, the support plate 10, and the vegetable leaves to perform micro-vibration. On the one hand, through micro-vibration combined with inclined air drying, under the action of vibration, it is beneficial to promote the separation of free water from the vegetable leaves and accelerate the drying efficiency. Under the action of inclination, both sides of the vegetable leaves are in the dry air flow, ensuring the uniformity of heat drying, without extending the air drying or vibration time, which is beneficial to reducing the energy consumption in the dehydration process. At the same time, it also avoids long-term vibration, which leads to the loss of nutrients in the vegetables. On the other hand, the vibration force generated by the micro-vibration is small, will not damage the surface of the vegetables, and is also beneficial to protecting the vegetables during the dehydration process. Furthermore, under the action of the airflow, the leaves can be made to stick to the surface of the support plate 10, which is also conducive to reducing the relative displacement between the leaves, thereby reducing the friction damage between the leaves, and further improving the protection of the vegetables; It should be noted that, since the support plate 10 is rotatably connected to the conveyor mesh belt 3, when the support plate 10 moves to the two end positions of the conveyor mesh belt 3, the support plate 10 needs to bend to adapt to the driving roller of the conveyor 2. Therefore, the traditional rigid support structure may be difficult to adapt to the curved area, and the flexible support structure is difficult to stably support the vegetable leaves. Therefore, the present invention fixes the first support airbag 7 on both sides of the flexible support plate 10. The first support airbag 7 has a built-in regulating pump. The regulating pump is used to inflate the first support airbag 7 to expand it, thereby stably supporting both ends of the support plate 10. , keeping the support plate 10 in a straight state, thereby ensuring the support effect of the support plate 10 on the vegetable leaves. When the support plate 10 is close to the driving roller position, the gas inside the first support airbag 7 is sucked out by adjusting the pump to deflate it. Since the support plate 10 itself is made of flexible material and the deflation process of the first support airbags 7 on both sides is controllable, the support plate 10 can smoothly fit the curved surface contour of the conveyor mesh belt 3 and successfully complete the turning action at both ends of the conveyor mesh belt 3, effectively avoiding the jamming phenomenon caused by the inability of the traditional rigid support structure to bend, and also overcoming the problem of insufficient supporting force of the fully flexible structure during the normal conveying stage.

[0032] As a further implementation scheme of the present invention, a flexible plate 12 is provided under the support plate 10, and a plurality of flexible support columns 13 are fixed on the top surface of the flexible plate 12. The flexible support columns 13 are inserted into the water-permeable holes 11. The flexible support columns 13 are made of porous material. Sliding bars 14 are fixed at both ends of the flexible plate 12. The two sliding bars 14 are vertically slidably connected to the connecting bar 5 and the movable bar 6 respectively. A spacing adjustment component is provided between the sliding bar 14 and the support plate 10. The spacing adjustment component is used to adjust the spacing between the support plate 10 and the flexible plate 12.

[0033] Specifically, the leaves of some vegetables are relatively soft. When blown by air, the leaves stick to the support plate 10. Although the stability of the leaves can be guaranteed, some leaves may sink into the water permeable holes 11, causing damage to the leaves. In order to solve the above problem, the present invention arranges a flexible plate 12 under the support plate 10, and fills the inside of the water permeable holes 11 with flexible support columns 13 on the surface of the flexible plate 12. On the one hand, the surface of the support plate 10 is smooth, which is conducive to protecting the leaves and reducing damage to the leaves. On the other hand, the flexible support columns 13 are made of porous material, for example, sponge material, which can actively absorb moisture on the surface of the leaves, thereby simultaneously ensuring the water permeability of the water permeable holes 11 in the process of protecting the leaves.

[0034] As a further embodiment of the present invention, the flexible plate 12 is a hollow structure, and an air pump 15 is fixed on the flexible plate 12. The flexible plate 12 is fixedly connected to the air pump 15 through a pipe. The flexible support column 13 is composed of a first sponge column 16 and a second sponge column 17. A bracket 31 is fixed to the bottom of the first sponge column 16, and a limiting ring 18 is fixed on the outer side of the bracket 31. The limiting ring 18 is fixed on the top surface of the flexible plate 12, and a drainage hole 19 is provided on the side wall of the limiting ring 18. The second sponge column 17 is arranged inside the limiting ring 18, and the top surface of the second sponge column 17 contacts the bottom surface of the first sponge column 16. A T-slot 20 is provided on the inside of the second sponge column 17, and a first airbag 21 is fixed in the upper chamber of the T-slot 20, and a second airbag 22 is fixed in the lower chamber of the T-slot 20. The first airbag 21 and the second airbag 22 are both connected to the interior of the flexible plate 12 through a conduit, and a regulating valve 23 is fixed in the conduit.

[0035] Specifically, porous materials are easily saturated, and the water absorption rate drops sharply after the internal pores are filled with water, which may affect the dehydration effect on the back of the vegetable leaves. Although the water in the porous material can be squeezed out by extrusion to ensure its water absorption effect, the conventional extrusion method may cause water to overflow from the top of the flexible support column 13, soaking the vegetable leaves for the second time, affecting the dehydration effect of the vegetable leaves. In order to solve the above problems, the present invention improves the flexible support column 13 and the extrusion method. The specific working method is as follows: by starting the air pump 15, the air is inflated into the flexible plate 12. At this time, the regulating valve 23 of the first airbag 21 is in the open state, and the second airbag 22 is in the closed state. The regulating valve 23 is in a closed state, and the gas enters the interior of the first airbag 21 through the regulating valve 23 of the first airbag 21. The first airbag 21 is a longitudinal telescopic airbag. After being inflated, it can expand longitudinally. The top of the first airbag 21 is blocked by the bracket 31, so that the first sponge column 16 is not squeezed, thereby preventing the first sponge column 16 from being squeezed and causing the vegetable leaves to be soaked for the second time. The downward expansion of the first airbag 21 can push the second sponge column 17 to separate from the first sponge column 16. Then, the regulating valve 23 of the first airbag 21 is closed, so that the second sponge column 17 is separated from the first sponge column 16, and the regulating valve 23 of the second airbag 22 is opened synchronously. , so that the gas in the flexible plate 12 enters the second airbag 22. The second airbag 22 is a transverse telescopic airbag. After inflation, it can expand laterally, so that the second airbag 22 and the limiting ring 18 cooperate to squeeze the second sponge column 17, and the moisture in the second sponge column 17 is discharged from the drainage hole 19. Part of the water flows out from the top of the second sponge column 17. At this time, the second sponge column 17 is separated from the first sponge column 16, thereby preventing the water from entering the first sponge column 16, resulting in excessive moisture in the first sponge column 16 and secondary soaking of the leaves. After drainage is completed, the air pump 15 is started to suck the water out of the flexible plate 12. The gas in the flexible support column 13 is discharged quickly, and the gas in the first air bag 21 and the second air bag 22 is quickly reset. The second sponge column 17 can also recover and rise to contact the first sponge column 16 again, and absorb the moisture inside the first sponge column 16, so that the first sponge column 16 is in an unsaturated state, ensuring the water absorption effect of the first sponge column 16. In summary, this embodiment intermittently squeezes the second sponge column 17, while ensuring the water absorption effect of the flexible support column 13, it also avoids secondary soaking of the leaves, thereby ensuring the dehydration efficiency of the leaves.

[0036] As a further embodiment of the present invention, the pores of the second sponge column 17 are larger than the pores of the first sponge column 16 .

[0037] Specifically, in the process of absorbing water through the flexible support column 13, the free water is first quickly adsorbed by the first sponge column 16 due to capillary force, forming initial water storage. Subsequently, due to the large pore size and small flow resistance of the second sponge column 17, the gradient drainage formed by the difference in pores between the upper and lower layers quickly transfers the water to the second sponge column 17 with large pores in the lower layer for storage, forming an efficient combination of water absorption in the upper layer and water storage and drainage in the lower layer, avoiding the premature saturation of the upper sponge due to insufficient water storage space, and further enhancing the water absorption efficiency of the first sponge column 16.

[0038] As a further embodiment of the present invention, a plurality of through grooves 24 are provided on the surface of the flexible plate 12 . The through grooves 24 are provided on one side of the limiting ring 18 . A plurality of guide protrusions 25 are fixed on both sides of the through grooves 24 on the flexible plate 12 .

[0039] Specifically, when the support plate 10 is in an inclined state, after the second sponge column 17 is squeezed, the discharged water will flow along the surface of the flexible plate 12. If it is not discharged in time, it will remain on the surface of the flexible plate 12 or flow into other limiting rings 18, which may interfere with the drainage or water absorption function of other second sponge columns 17. The present invention provides a through groove 24 on one side of the limiting ring 18. When the flexible plate 12 is tilted, the water flow is squeezed out and guided by the guide protrusion 25. It can directly flow into the through groove 24 and be discharged to the back side of the flexible plate 12, thereby avoiding interference with other second sponge columns 17.

[0040] As a further embodiment of the present invention, the spacing adjustment assembly includes a telescopic tube 26, which is fixed between the sliding bar 14 and the support plate 10. The telescopic tube 26 is connected to the interior of the flexible plate 12 through a connecting tube 27, and a control valve 28 is fixedly connected to the connecting tube 27.

[0041] Specifically, in food processing, some products have high requirements for the dehydration effect of vegetable leaves. Although the flexible support column 13 can absorb free water on the surface of the vegetable leaves through contact, its contact area is limited, and its effect on deep moisture and large areas is weak. Therefore, it is necessary to form a ventilation channel on the back of the vegetable leaves to improve the dehydration efficiency. However, in the early stage of dehydration, the vegetable leaves have high water content and soft texture. Under the action of airflow, the back is easy to fit tightly with the support plate 10, resulting in difficulty in air circulation. As the dehydration process progresses, the vegetable leaves gradually dry and harden due to water loss. At this time, by opening the control valve 28 and starting the air pump 15 to absorb the gas in the telescopic tube 26, the telescopic tube 26 is shortened. Pull the flexible plate 12 upward to drive the flexible support column 13 to move toward the outside of the water-permeable hole 11, stably lifting the vegetable leaves and forming a breathable gap on the back of the leaves. The flexible support column 13 can connect the upper and lower spaces of the support plate 10. This design, with the help of the improved deformation resistance of the vegetable leaves after hardening, avoids the damage that may be caused by the initial soft leaf support, enables the dry airflow to act on both sides of the vegetable leaves at the same time, effectively breaks the stagnant air layer at the joint, constructs a two-way mass transfer channel, and significantly accelerates the evaporation rate of water. In particular, the dehydration efficiency of thin-leaf vegetables is significantly improved, which not only solves the limitations of surface adsorption, but also optimizes the removal effect of deep moisture through structural adaptation; Furthermore, since the flexible support column 13 is made of flexible material, its elastic deformation ability allows it to swing synchronously with the leaves during vibration, maintaining a relatively static state with the leaves, avoiding rigid friction or sliding displacement between the two, thereby reducing friction and wear between the leaves, which is beneficial to further protect the leaves.

[0042] As a further embodiment of the present invention, a plurality of ventilation grooves 29 are provided on the side wall of the first sponge column 16 , and the bottom of the ventilation grooves 29 passes through the first sponge column 16 .

[0043] Specifically, although gas can enter the space between the back of the vegetable leaf and the support plate 10 through the first sponge column 16, in the initial stage of lifting the vegetable leaf, some water may be stored in the first sponge column 16, and some of the internal pores are filled with water, resulting in a reduction in the gas channel. Therefore, it is difficult to maintain efficient ventilation by relying solely on the pores of the main body. The present invention improves the structure of the first sponge column 16, and opens a ventilation groove 29 on the side wall of the first sponge column 16. The top of the ventilation groove 29 does not pass through the first sponge column 16, thereby ensuring that the first sponge column 16 can continue to maintain the flatness of the surface of the support plate 10 when filling the water-permeable hole 11. When the first sponge column 16 lifts the vegetable leaf, the top of the ventilation groove 29 is located above the support plate 10, and the bottom end is located below the support plate 10. The upper and lower ends of the support plate 10 can be directly connected through the ventilation groove 29, thereby facilitating the gas to enter the space between the back of the vegetable leaf and the support plate 10 from the position of the ventilation groove 29, accelerating the gas flow on the back of the vegetable leaf, and thereby reducing the adverse effect of residual moisture in the first sponge column 16 on the passage of gas.

[0044] As a further embodiment of the present invention, a groove 30 is provided on the bottom surface of the movable bar 6, a magnet 32 ​​is slidably connected inside the groove 30, a spring 33 is fixed between the magnet 32 ​​and the top surface of the groove 30, and the magnet 32 ​​is magnetically connected to the conveyor belt 3.

[0045] Specifically, when the support plate 10 is not tilted, under the adsorption action of the magnet 32, one end of the support plate 10 can be stably adsorbed on the conveyor mesh belt 3, thereby maintaining the stability of the support plate 10 when passing through the bending position of the conveyor belt. When the support plate 10 is flipped and tilted, the magnet 32 ​​gradually moves away from the conveyor mesh belt 3 and shrinks into the groove 30 under the pulling action of the spring 33.

[0046] As a further embodiment of the present invention, flip plates 34 are symmetrically arranged on both sides of the support plate 10, one end of the flip plate 34 is fixed on the first support airbag 7, and the other end of the flip plate 34 is fixed to the second support airbag 35, one end of the second support airbag 35 is fixed to the connecting strip 5, and a pushing assembly is provided at the bottom of the other end of the second support airbag 35. When the support plate 10 is tilted, the pushing assembly pushes the second support airbag 35 upward, and the pushing assembly includes a pushing block 36, which is fixed on the bottom surface of the second support airbag 35, and the bottom of the pushing block 36 is fixed to the magnet 32 ​​through a connecting rod 37.

[0047] Specifically, the vegetable leaves are spread flat on the top surface of the support plate 10. After the support plate 10 is flipped, when the support plate 10 is in a vibrating state, the vegetable leaves at the edge of the support plate 10 may reciprocate and collide with the shell of the conveyor 2, causing the vegetable leaves at the edge of the support plate 10 to be easily damaged. In order to solve the above problem and reduce the damage to the vegetable leaves at the edge of the support plate 10, the present invention symmetrically arranges flip plates 34 on both sides of the support plate 10, and the flip plates 34 are fixed to the magnets 32 by pushing blocks 36. When the support plate 10 is in a horizontal state, the magnets 32 are adsorbed on the conveyor mesh belt 3. At this time, the flip plates 34 are in a horizontal state, keeping the support plate 10 , the overall flatness of the flip plate 34, so that it can better receive the leaves. When the support plate 10 is tilted, the magnet 32 ​​gradually moves away from the conveyor belt 3 and is pulled by the spring 33 to move toward the inside of the groove 30, thereby driving the push block 36 to move upward through the magnet 32, so that one end of the flip plate 34 moves upward, so that the surface of the flip plate 34 is tilted toward one side of the support plate 10. Under the inclined guidance and vibration of the flip plate 34, the leaves on both sides of the support plate 10 can be gathered to the middle, thereby avoiding direct collision between the edge leaves and the shell, which is beneficial to reduce damage to the leaves at the edge of the support plate 10.
