Description

[0002] In fruit juice processing production, material conveying is an indispensable link in continuous operation. At present, the industry generally uses belt conveying devices to transfer raw materials such as fruits, especially after the cleaning process, fruits are often sent to the next processing section by a belt conveyor. However, this method has obvious defects in actual application: the free water stains carried on the surface of the fruit will drip or seep onto the surface of the conveying belt during the conveying process, and mix with the organic residues such as pomace and sugar attached to the surface of the belt at the same time, forming a sticky layer. With the passage of time, such residues are extremely easy to become a breeding ground for microorganisms in a humid environment, and bacteria, mold and other pollutants may multiply in large numbers. This not only leads to the deterioration of the cleaning condition of the conveying belt itself, but also cross-contaminates the subsequent contacted fruit materials during continuous operation, ultimately affecting the health and safety of the fruit juice and the product quality, and constitutes a potential risk in the production process.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] This embodiment specifically discloses a residue-preventing transport device for juice processing and production. It mainly proposes a method to reduce and clean residues on the conveyor belt and clean the transported fruit from all angles, thereby ensuring the quality of the transported fruit.

[0029] Combination Figures 1-3 As shown, the device includes a housing 1. A control panel is mounted on the front side of the housing 1. A support frame 2 is fixed to the upper surface of the housing 1. A first drive shaft 3 and a second drive shaft 4 are rotatably mounted on the left and right sides of the support frame 2, respectively. A first rotating wheel 5 is rotatably mounted on both the front and rear sides of the second drive shaft 4. A first conveyor belt 6 is wound between the first drive shaft 3 and the first rotating wheel 5. Both the first drive shaft 3 and the first rotating wheel 5 are patterned to increase the friction between them and the first conveyor belt 6. This is prior art and is not shown in detail in the attached figure. The first conveyor belt 6 has multiple through holes for the first conveyor belt... Water on the upper surface of the first conveyor belt 6 flows through and into the housing 1. A support 7 is fixed to the front side of the support frame 2. A first motor 8, which is electrically connected to the control panel, is fixed to the support 7. The output shaft of the first motor 8 is driven by a first gearbox 9 through a first transmission shaft 3. The first gearbox 9 is fixed to the housing 1. The housing 1 is used to store the liquid used to clean the first conveyor belt 6. The lower part of the first conveyor belt 6 is lower than the upper surface of the housing 1. The support frame 2 is equipped with a rinsing unit, and the support 7 is equipped with a driving unit. The rinsing unit is used to rinse the conveyed material, and the driving unit is used to retrieve the conveyed material, so that the rinsing unit can rinse the conveyed material.

[0030] Combination Figure 1 and Figure 4 As shown, the rinsing unit includes two first fixed frames 21 symmetrically distributed front and rear. Both first fixed frames 21 are fixed to the support frame 2. A first rotating pipe 22 is arranged between the two first fixed frames 21. Multiple nozzles are arranged in the middle of the lower surface of the first rotating pipe 22, and the nozzles are arranged vertically downward. A first conduit 23 is arranged at the rear of the first rotating pipe 22. A pump body 24 electrically connected to the control panel is fixed to the support frame 2. The pump body 24 is used to draw liquid from the housing 1 into the first conduit 23. The liquid sprayed by the nozzles on the first rotating pipe 22 is used to rinse the upper surface of the first conveyor belt 6 and the fruit on it, reducing the adhesion of the adhering substances on the first conveyor belt 6 and assisting the adhering substances on the fruit surface to fall off, ensuring the cleanliness of the fruit, thereby ensuring the quality of the juice processed subsequently.

[0031] Combination Figures 1-3 As shown, the driving unit includes a second motor 10 electrically connected to the control panel. The second motor 10 is fixed to the support 7 and is located to the right of the first motor 8. The output shaft of the second motor 10 is driven by a second gearbox 11, which is fixed to the support frame 2. Second wheels 12 are rotatably mounted on both the front and rear ends of the first transmission shaft 3. A second conveyor belt 13 is wound around each of the two second wheels 12 and the second transmission shaft 4. Patterns are provided on both the second transmission shaft 4 and the second wheels 12 to increase the friction between them and the second conveyor belt 13. Twelve equally spaced first fixing plates 14 are fixed to the outer surface of the second conveyor belt 13. This number is the specific number shown in the attached figure; the actual number can be adjusted according to actual needs. Adjustments are made accordingly. A sliding frame 15 is provided between two corresponding first fixed plates 14 on the two second conveyor belts 13. The sliding frame 15 is used to push the fruit to move on the surface of the first conveyor belt 6. An elastic belt 16 is fixed between two adjacent first fixed plates 14 on the same second conveyor belt 13, and the elastic belt 16 is fixed to the outer surface of the adjacent second conveyor belt 13. The elastic belt 16 is set in a wave shape. When the elastic belt 16 passes through a bend, the elastic belt 16 deforms accordingly. During this process, the elastic belt 16 is used to prevent the fruit from sliding off the first conveyor belt 6. The support frame 2 is rotatably provided with multiple rotating rollers 17. The rotating rollers 17 contact the inner side of the first conveyor belt 6. The rotating rollers 17 are used to support the first conveyor belt 6 and ensure that the first conveyor belt 6 drives the fruit to move stably.

[0032] The specific operation of the residue-preventing transportation device for fruit juice processing in this embodiment is as follows:

[0033] During the process of transporting cleaned fruit, the user controls the first motor 8, the second motor 10, and the pump body 24 via the control panel. The output shaft of the first motor 8 drives the first transmission shaft 3 to rotate through the first gearbox 9. The first transmission shaft 3 drives the first conveyor belt 6, which is wrapped around its outer side, to rotate. The output shaft of the second motor 10 drives the second transmission shaft 4 to rotate through the second gearbox 11. The rotation of the second transmission shaft 4 drives the two second conveyor belts 13, which are wrapped around its outer side, to rotate. The two second conveyor belts 13 simultaneously drive the first fixed plate 14, the sliding frame 15, and the elastic belt 16 connected to them to move. Under the synchronous movement of the sliding frame 15 and the first conveyor belt 6, the sliding frame 15 picks up the fruit floating on the water surface inside the shell 1, so that the fruit is located on the upper surface of the first conveyor belt 6. Subsequently, with the synchronous movement of the sliding frame 15 and the first conveyor belt 6, the fruit is continuously transported to the next processing stage.

[0034] During the conveying process, the lower part of the first conveyor belt 6 is immersed in the water stored in the housing 1, causing the residues attached to the first conveyor belt 6 to fall off. Subsequently, under the dual action of the circulating flow of the liquid in the housing 1 and the filter screen, the residues in the water gather near the filter screen, preventing bacteria from growing on the first conveyor belt 6.

[0035] During the above-mentioned conveying process, the pump body 24 works to draw water from the housing 1 into the first conduit 23, and then the water enters the first rotating pipe 22 and is sprayed out from the nozzle on it. The sprayed water sprays onto the surface of the fruit conveyed on the first conveyor belt 6, further washing away the adhering substances on the surface of the fruit, thereby ensuring the quality of the juice processed later. At the same time, the sprayed water washes the surface of the first conveyor belt 6, further reducing the amount of residue adhering to the first conveyor belt 6. The subsequently sprayed liquid re-enters the housing 1 through the through hole on the first conveyor belt 6.

[0036] If the fruit being transported is large, the user first selects the appropriate setting on the control panel to make the output shaft speed of the second motor 10 lower than that of the first motor 8. This causes the first conveyor belt 6 to move at a higher speed than the sliding frame 15. During the movement of the fruit between the first conveyor belt 6 and the sliding frame 15, the fruit accumulates in the gap between the sliding frame 15 and the first conveyor belt 6. Subsequently, due to the speed difference between the sliding frame 15 and the first conveyor belt 6, the fruit in the gap between the sliding frame 15 and the first conveyor belt 6 rotates, allowing the water sprayed from the nozzles on the first rotating pipe 22 to thoroughly rinse the surface of the fruit, ensuring that the transported fruit remains clean.

[0037] Example 2

[0038] This embodiment specifically discloses an anti-residue transportation device for fruit juice processing and production. Based on Embodiment 1, it also has an adaptability adjustment function for transporting fruits of different volumes.

[0039] Combination Figure 2 and Figure 5 As shown, it also includes a third motor 18 electrically connected to the control panel. The third motor 18 is fixed to the support 7 and is located between the first motor 8 and the second motor 10. The output shaft of the third motor 18 is fixed to a rotating shaft 19 rotatably connected to the support frame 2. The rotating shaft 19 is provided with two external threads symmetrically distributed front and back. The first transmission shaft 3 and the second transmission shaft 4 are slidably provided with two sliding frames 20 symmetrically distributed front and back, and the two sliding frames 20 are respectively threaded to the two external threads on the rotating shaft 19, for controlling the relative movement of the two sliding frames 20 or The sliding frame 15 moves in opposite directions and is slidably connected to the adjacent first fixed plate 14. A tension spring is fixed between the sliding frame 15 and the adjacent first fixed plate 14. The tension spring is always in a stretched state. Ball bearings are provided at both ends of the sliding frame 15. The sliding frame 20 contacts the ball bearings of the sliding frame 15 to reduce the friction between them. By changing the contact position between the ball bearings on the sliding frame 15 and the sliding frame 20, the movement trajectory of the sliding frame 15 is changed, so that the distance between the middle of the sliding frame 15 and the first conveyor belt 6 is different, which makes it easier for the sliding frame 15 to pick up fruits of different sizes.

[0040] The working principle described above is as follows:

[0041] During the conveying of fruits of different sizes, the user controls the third motor 18 via the control panel. The output shaft of the third motor 18 drives the rotating shaft 19 to rotate a specified number of times. The rotation of the rotating shaft 19 causes the two sliding frames 20 to move relative to each other through its external thread. Under the tension of the tension spring connected to the sliding frame 15, the ball end of the sliding frame 15 remains in contact with the inner side of the sliding frame 20 after the sliding frame 20 moves. After the sliding frame 20 is adjusted, the movement trajectory of the ball end of the sliding frame 15 is changed. During this process, the sliding frame 15 moves along the adjacent first fixed plate 14, changing the distance between the sliding frame 15 and the first conveyor belt 6, making it easier for the sliding frame 15 to pick up fruits of different sizes. This allows the device to convey fruits of different sizes, improving its applicability. After the position of the sliding frame 15 is adjusted, the user starts the device via the control panel and then repeats the above conveying operation.

[0042] Example 3

[0043] This embodiment specifically discloses a residue-proof transportation device for fruit juice processing and production. Based on Embodiment 2, it also has the function of drying the fruit during the process.

[0044] Combination Figure 1 , Figure 4 , Figure 6 and Figure 7As shown, it also includes three second rotating tubes 25, all of which are rotatably mounted between two first fixed frames 21. Multiple nozzles are located in the middle of the lower surface of each second rotating tube 25. The three second rotating tubes 25 are connected to a second conduit 26, and the second conduit 26 and the three second rotating tubes 25 are all rotatably connected in a sealed manner. An air pump 27 connected to the second conduit 26 is fixedly attached to the rear surface of the support frame 2. Two second fixed plates 28, symmetrically distributed front and rear, are fixedly attached to the lower surface of the first rotating tube 22. The two second fixed plates 28 are located on the front and rear sides of the nozzles on the first rotating tube 22. The first rotating tube 22 is rotatably connected to the first fixed frame 21, and a torsion spring is fixed between the first rotating tube 22 and the front first fixed frame 21. In the initial state, the nozzles of the first rotating tube 22 are vertically downwards, and the second fixed plates 28... Also in a vertical position, the sliding frame 15 is used to squeeze the second fixed plate 28 to swing, so that the nozzle on the first rotating tube 22 swings and sprays liquid. The first rotating tube 22 and the two adjacent parts of the three second rotating tubes 25 are all driven by pulleys and belts, so that the four can rotate synchronously. The first fixed frame 21 on the front side is fixedly connected to the second fixed frame 29. The second fixed frame 29 is fixedly connected to five elastic blocks 30 distributed circumferentially. The elastic blocks 30 are in contact with the first rotating tube 22. When the first rotating tube 22 rotates clockwise, the first rotating tube 22 squeezes the elastic blocks 30 away from its rotation center. When the first rotating tube 22 rotates counterclockwise, the first rotating tube 22 squeezes the elastic blocks 30 closer to its rotation center. At this time, the elastic blocks 30 deform and squeeze the first rotating tube 22, that is, it hinders and delays the counterclockwise rotation of the first rotating tube 22.

[0045] The working principle described above is as follows:

[0046] During the fruit transport process, the control panel simultaneously starts the air pump 27, which injects gas into the second conduit 26. The gas is then sprayed out through the nozzle on the second rotating pipe 25. The sprayed gas blows onto the fruit transported on the surface of the first conveyor belt 6, keeping the fruit dry and facilitating subsequent processing of the fruit in the next stage.

[0047] When the sliding frame 15 moves past the second fixed plate 28, it presses against the second fixed plate 28 and causes it to swing, thereby causing the first rotating tube 22 to rotate and twist the torsion spring connected to it. The rotation of the first rotating tube 22 causes the water sprayed from its nozzle to continuously wash the fruit. The rotation of the first rotating tube 22 drives the second rotating tube 25 to rotate synchronously through the pulley and belt. The rotation of the second rotating tube 25 causes its nozzle to continuously blow on the fruit. After the sliding frame 15 passes the second fixed plate 28, under the torsion of the torsion spring connected to the first rotating tube 22, the first rotating tube 22 rotates in the opposite direction. At this time, the rotation of the first rotating tube 22 will compress the elastic block 30 and cause it to deform. The deformation of the elastic block 30 increases the compressive force between it and the first rotating tube 22, thereby increasing the friction between the two and delaying the reverse rotation of the first rotating tube 22.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
