Description

Technical Field

[0001] This utility model relates to the field of fruit processing equipment technology, and in particular to a sterilization treatment device for fruit processing. Background Technology

[0002] After harvesting, fruits need to be sterilized to prevent them from spoiling quickly during transportation. For larger fruits such as durian, jackfruit, and durian honey, the surface is easily punctured or scratched during harvesting and stacking due to their weight, allowing bacteria to easily penetrate the fruit. Therefore, timely disinfection is necessary. In addition, oddly shaped fruits such as durian can easily block the fungicide, affecting its complete and even adhesion to the fruit surface.

[0003] Most existing sterilization devices place the fruit in a rotating frame. By rotating the frame, the fruit to be sterilized rotates while the sterilizer is sprayed onto the fruit surface. However, this method is not convenient to use with other conveying machinery. Workers need to manually place the fruit into the frame and then manually remove it after sterilization, which consumes a lot of manpower. In addition, existing sterilization devices usually use a single fixed spray head to spray the sterilizer, which cannot completely and evenly coat the surface of some oddly shaped fruits. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to propose a sterilization treatment device for fruit processing, so as to solve the problems that the existing sterilization device is not convenient to be used with other conveying machinery, requires workers to pick up and put down the fruit, and cannot completely and evenly spray the sterilizing agent onto the surface of the fruit.

[0005] A sterilization treatment device for fruit processing includes: a conveying component, a spraying component, and a turning component;

[0006] The conveying assembly includes two rotating rollers, a mesh conveyor belt, and a drive motor. The mesh conveyor belt is wound around both rotating rollers, and the output shaft of the drive motor is fixedly connected to the rotating rollers.

[0007] The spraying assembly includes a spray head located above the mesh conveyor belt, with a gap between the spray head and the mesh conveyor belt allowing fruit to pass through;

[0008] The flipping assembly includes a blocking frame, a locking bar, an electric push rod, and a pushing frame. The flipping assembly and the mesh conveyor belt form a passage for fruit to pass through. The blocking frame is swayably set above the mesh conveyor belt to close or open the passage. A locking bar is fixed to the blocking frame. The electric push rod is a horizontally set telescopic rod with a pushing frame fixed to it. The locking bar is located on the side of the pushing frame closer to the blocking frame, so that the pushing frame can push the blocking frame to swing away from the mesh conveyor belt through the locking bar.

[0009] Preferably, the barrier frame further includes support rollers and a barrier belt. Two support rollers are rotatably arranged on the barrier frame, and the two support rollers are together wrapped with a barrier belt for contacting the fruit.

[0010] Preferably, the spraying assembly further includes a swing mechanism, which includes a slotted plate, a stepper motor, and a toggle frame. The spray head, which is fixed to the slotted plate, is rotatably disposed above the mesh conveyor belt. One end of the toggle frame is fixed to the output shaft of the stepper motor, the other end of the toggle frame is offset from the axis of the output shaft of the stepper motor, and the other end of the toggle frame is slidably connected to the slotted plate.

[0011] Preferably, the flipping assembly further includes a limiting block, and the limiting block is fixed to one end of the push frame near the locking rod. The limiting block is provided with a limiting groove for supporting the locking rod. When the locking rod is located in the limiting groove, the limiting block supports the blocking frame through the locking rod.

[0012] Preferably, there are two spray heads, both of which are tilted at 15 to 30 degrees toward the centerline of the support strip.

[0013] Preferably, a number of support belts for contacting the fruit are fixed to the mesh conveyor belt.

[0014] Preferably, a receiving tray with an open top is provided below the mesh conveyor belt, and the projected area of ​​the receiving tray in the vertical direction is larger than that of the mesh conveyor belt.

[0015] Preferably, two baffles are symmetrically arranged above the mesh conveyor belt, with a gap between the baffles and the mesh conveyor belt that prevents fruit from passing through, and a space between the two baffles for fruit to pass through. The spray head is located between the two baffles in the horizontal direction.

[0016] Preferably, a protective frame is provided above the mesh conveyor belt, the inside of the protective frame has a space for sterilization, and soft plates are provided on both sides of the protective frame, the soft plates being made of flexible material.

[0017] Beneficial effects: 1. The rotating roller drives the mesh conveyor belt to rotate, and the rotation of the mesh conveyor belt causes the fruit to move towards the other end of the top surface of the mesh conveyor belt. During the movement of the fruit, it comes into contact with the blocking frame. At this time, the fungicide sprayed by the spray head falls on the surface of the fruit. The mesh conveyor belt continues to rotate, and the fruit is blocked by the blocking frame and cannot continue to move. The mesh conveyor belt pushes the bottom surface of the fruit. At the same time, the fruit is blocked by the side of the mesh conveyor belt. Since the angle between the side of the blocking frame and the mesh conveyor belt is 120 degrees, the part of the fruit in contact with the side of the blocking frame moves obliquely upward along the side of the blocking frame. In this way, when the fruit is blocked by the blocking frame, the mesh conveyor belt can drive the fruit to rotate, thereby rotating the fruit on the mesh conveyor belt, so that the fungicide falls on the surface of the rotating fruit, making the surface of the fruit fully and evenly coated with fungicide, and thus fully and evenly sterilizing the surface of the fruit.

[0018] 2. The contact portion between the fruit and the blocking belt moves obliquely upward along the blocking belt, while the fruit drives the blocking belt to rotate around the two support rollers. When the mesh conveyor belt can drive the fruit to rotate, the friction between the blocking frame and the fruit is reduced, thereby protecting the integrity of the fruit peel during the sterilization process.

[0019] 3. When it is necessary to spray fungicide on the surface of fruit, the stepper motor drives the actuating frame to rotate. The rotation of the actuating frame causes the slotted plate, support frame and spray head to swing slightly. When the spray head swings slightly, the fungicide can fall more evenly on the surface of the fruit, thus ensuring that the surface of the fruit is covered with an appropriate amount of fungicide for sterilization.

[0033] like Figures 1-8 As shown, a sterilization treatment device for fruit processing includes: a main frame 10, a conveying component 20, a spraying component 30 and a flipping component 40, with a guide frame 11 provided on the upper part of the main frame 10;

[0034] The conveying assembly 20 includes two rotating rollers 21, a mesh conveyor belt 22, and a drive motor 23. The two rotating rollers 21 are rotatably connected to the middle of the main frame 10, and the mesh conveyor belt 22 is wound around the two rotating rollers 21. The drive motor 23 is fixedly connected to the middle of the main frame 10, and the output shaft of the drive motor 23 is fixedly connected to one of the rotating rollers 21.

[0035] like Figure 7 As shown, the spraying assembly 30 includes a support frame 31 and a spray head 32. The support frame 31 is located on the upper end of the main frame 10, and the spray head 32 is fixedly connected to the support frame 31. The spray head 32 is located above the mesh conveyor belt 22 and faces the mesh conveyor belt 22. The gap between the spray head 32 and the mesh conveyor belt 22 allows fruit to pass through.

[0036] like Figure 6As shown, the flipping assembly 40 includes a blocking frame 41, a locking rod 42, an electric push rod 43, and a pushing frame 44. A passageway for fruit to pass through is formed between the flipping assembly 40 and the mesh conveyor belt 22. The blocking frame 41 is swayably positioned above the main frame 10 to close or open the passageway. When the blocking frame 41 is vertically downward under its own weight, the angle between the side of the blocking frame 41 and the mesh conveyor belt 22 is 120 degrees. When the mesh conveyor belt 22 moves the fruit, the fruit will contact the side of the blocking frame 41. The blocking frame 41 is located above the mesh conveyor belt 22. The blocking frame 41 swings to approach the mesh... When the mesh conveyor belt 22 is in position, the blocking frame 41 is suitable for blocking the fruit from passing through. When the blocking frame 41 swings to a position away from the mesh conveyor belt 22, the blocking frame 41 will not block the fruit from passing through. A locking rod 42 is fixedly connected to the blocking frame 41. The pushing frame 44 is horizontally slidably set on the guide frame 11. The electric push rod 43 is fixedly connected to the guide frame 11. The electric push rod 43 is a horizontally set telescopic rod with the pushing frame 44 fixedly connected to it. The locking rod 42 is located on the side of the pushing frame 44 close to the blocking frame 41, so that the pushing frame 44 can push the blocking frame 41 to swing away from the mesh conveyor belt 22 through the locking rod 42.

[0037] The worker starts the drive motor 23 and the electric push rod 43. The worker introduces the fungicide into the spray head 32 through the connecting hose 33, and then the fungicide is sprayed out through the spray head 32. The worker intermittently places the fruit to be sterilized at one end of the top surface of the mesh conveyor belt 22. The drive motor 23 drives the rotating roller 21 to rotate, and the rotating roller 21 drives the mesh conveyor belt 22 to rotate. The rotation of the mesh conveyor belt 22 moves the fruit towards the other end of the top surface of the mesh conveyor belt 22. During the movement, the fruit comes into contact with the blocking frame 41. At this time, the fungicide sprayed from the spray head 32 falls on the surface of the fruit. The mesh conveyor belt 22 continues to rotate, and the fruit cannot continue to move due to the obstruction of the blocking frame 41. The mesh conveyor belt 22 pushes the bottom surface of the fruit, while the fruit is blocked by the side of the mesh conveyor belt 22. Since the angle between the side of the blocking frame 41 and the mesh conveyor belt 22 is 120 degrees, the fruit and the... The contact portion on the side of the blocking frame 41 moves obliquely upward along the side of the blocking frame 41. Thus, when the fruit is blocked by the blocking frame 41, the mesh conveyor belt 22 can drive the fruit to rotate. This rotation of the fruit on the mesh conveyor belt 22 allows the fungicide to fall onto the surface of the rotating fruit, ensuring that the fungicide is fully and evenly adhered to the fruit surface, thereby thoroughly and evenly sterilizing the fruit surface. Then, the electrical control system controls the extension of the telescopic rod of the electric push rod 43. The extension of the telescopic rod of the electric push rod 43 drives the push frame 44 to move. During the movement of the push frame 44, the push rod 42 and the blocking frame 41 swing, so that the blocking frame 41 no longer blocks the fruit. The mesh conveyor belt 22 continues to rotate, driving the fruit to the other end of the top surface of the mesh conveyor belt 22. Then, the mesh conveyor belt 22 transports the fruit to the next process, eliminating the need for workers to manually pick up and put down the fruit, saving manpower.

[0038] More preferably, such as Figure 5 , Figure 6 and Figure 8 As shown, the blocking frame 41 also includes a support roller 411 and a blocking belt 412. Two support rollers 411 are rotatably arranged on the blocking frame 41. The two support rollers 411 are wrapped together with a blocking belt 412 for contacting the fruit. When the blocking frame 41 is vertically downward under its own weight, the angle between the blocking belt 412 and the mesh conveyor belt 22 is 120 degrees.

[0039] During the movement of the fruit, it comes into contact with the blocking belt 412 on the blocking frame 41. The mesh conveyor belt 22 continues to rotate, and the fruit cannot continue to move due to the obstruction of the blocking belt 412. The mesh conveyor belt 22 pushes the bottom of the fruit. Because the angle between the blocking belt 412 and the mesh conveyor belt 22 is 120 degrees, the contact part between the fruit and the blocking belt 412 moves obliquely upward along the blocking belt 412. The fruit drives the blocking belt 412 to rotate around the two support rollers 411. When the mesh conveyor belt 22 can drive the fruit to rotate, the friction between the blocking frame 41 and the fruit is reduced, thereby protecting the integrity of the fruit peel during the sterilization process. When the fruit is durian, it can protect the sharp spikes on the surface of the durian to maintain the appearance of the durian surface.

[0040] More preferably, such as Figure 5 , Figure 7 and Figure 8 As shown, the spraying assembly 30 also includes a swing mechanism 34, which includes a slotted plate 341, a stepper motor 342, and a toggle frame 343. The slotted plate 341 is fixedly connected to the support frame 31. The spray head 32 is rotatably mounted on the main frame 10 through the support frame 31. One end of the toggle frame 343 is fixedly connected to the output shaft of the stepper motor 342, and the other end of the toggle frame 343 is offset from the axis of the output shaft of the stepper motor 342. The other end of the toggle frame 343 is slidably connected to the slotted plate 341.

[0041] When it is necessary to spray fungicide on the surface of fruit, the electronic control system starts the stepper motor 342, which drives the actuating frame 343 to rotate. The rotation of the actuating frame 343 causes the slotted plate 341, the support frame 31 and the spray head 32 to swing slightly. When the spray head 32 swings slightly, the fungicide can fall more evenly on the surface of the fruit, thereby ensuring that the surface of the fruit is covered with an appropriate amount of fungicide for sterilization.

[0042] More preferably, such as Figure 5 , Figure 6 and Figure 8As shown, the flipping assembly 40 also includes a limiting block 45. The end of the push frame 44 near the locking rod 42 is fixed to the limiting block 45. The limiting block 45 is provided with a limiting groove for supporting the locking rod 42. When the locking rod 42 is located in the limiting groove, the limiting block 45 supports the blocking frame 41 through the locking rod 42.

[0043] Initially, the lever 42 is located in the limiting groove. When the fruit comes into contact with the blocking frame 41, the limiting block 45 supports the blocking frame 41 through the lever 42. When sterilizing heavier fruits, the blocking frame 41 can also block the fruit, so that the blocking frame 41 can work with the mesh conveyor belt 22 to rotate the heavier fruit.

[0044] More preferably, such as Figure 7 As shown, there are two spray heads 32, and both spray heads 32 are tilted at 15 to 30 degrees toward the centerline of the support strip 24.

[0045] When sterilizing larger fruits, such as durian and jackfruit, the two spray heads 32 spray the fungicide onto the fruit surface from both sides. This reduces the uneven distribution of the fungicide caused by the obstruction of the fungicide due to the odd shape of the fruit, thus making the fungicide fall more evenly on the fruit surface.

[0046] More preferably, such as Figure 5 As shown, several support belts 24 for contacting the fruit are fixed to the mesh conveyor belt 22. The support belts 24 are made of flexible material and have a thickness of 1 to 3 centimeters.

[0047] The mesh conveyor belt 22 supports the fruit through the support belt 24. During the placement and rotation of the fruit, the support belt 24 can cushion the fruit, thereby protecting its integrity.

[0048] More preferably, such as Figure 4 As shown, a receiving plate 12 with an open top is provided below the mesh conveyor belt 22, and the projected area of ​​the receiving plate 12 in the vertical direction is larger than that of the mesh conveyor belt 22.

[0049] The receiving tray 12 is used to receive the disinfectant falling from the mesh conveyor belt 22, making it convenient for workers to collect and dispose of the disinfectant.

[0050] More preferably, such as Figure 2 , Figure 3 and Figure 4 As shown, two baffles 13 are symmetrically arranged above the mesh conveyor belt 22. Both baffles 13 are fixed to the middle of the main frame 10. There is a gap between the baffles 13 and the mesh conveyor belt 22 that the fruit cannot pass through. There is a space between the two baffles 13 that allows the fruit to pass through. The spray head 32 is located between the two baffles 13 in the horizontal direction.

[0051] Two baffles 13 work together to restrain the fruit and prevent it from rolling off the mesh conveyor belt 22.

[0052] More preferably, such as Figure 1 , Figure 2 and Figure 3 As shown, a protective frame 50 is provided above the mesh conveyor belt 22. The protective frame 50 has a space for sterilization inside. The spray head 32 and the baffle frame 41 are located inside the protective frame 50. Soft plates 51 are provided on both sides of the protective frame 50. The soft plates 51 are made of flexible material.

[0053] The protective frame 50 and the flexible plate 51 work together to block the disinfectant, thereby reducing the amount of disinfectant that may be dispersed into the air.

[0054] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
