Description

Technical Field

[0001] The invention relates to the technical field of milk tea pearl packaging, in particular to an automatic packaging device for milk tea pearl production. Background Art

[0002] Milk tea pearls, also known as tapioca pearls, are the key ingredient in bubble tea. The main raw material of tea pearls is starch, among which tapioca starch is the most commonly used. Tapioca starch gives the pearls a chewy and smooth taste.

[0003] After the production of milk tea pearls is completed, they are usually packaged and transported. However, the existing automatic packaging and sealing device lacks a dehumidification device for the milk tea pearls when packaging the milk tea pearls. Since the milk tea pearls are made of cassava, the milk tea pearls have strong hygroscopicity after production. If the milk tea pearls are not dried and dehumidified but directly packaged, not only will the milk tea pearls lack chewiness and affect the taste of the milk tea pearls, but the damp milk tea pearls are easily moldy during packaging and transportation, affecting the packaging and transportation safety of the milk tea pearls.

[0021] The interior of the rotating boxes 14 on both sides is provided with a jet pipe 23, which is connected to the interior of the rotating rod 12. The inner wall of the jet pipe 23 is slidably connected with a pushing member 25. A pressing spring 27 is provided on the outer wall of the pushing member 25. The end of the pressing spring 27 away from the pushing member 25 is in contact with the interior of the jet pipe 23. A plurality of air jet branch pipes 36 are connected to the interior of the jet pipe 23. The ends of the plurality of air jet branch pipes 36 are commonly connected to an air jet box 28. A plurality of air jet holes are provided at the bottom of the air jet box 28, and a vibrating magnet is provided at the bottom of the air jet box 28.

[0022] A baffle plate 22 is provided inside the rotating rod 12, and a circulation hole 24 is provided on the baffle plate 22. Two slide rails 31 are provided on both sides of the circulation hole 24. The inner side walls of the two slide rails 31 are slidably connected with a shielding cover 29. An inner spring 50 is provided inside the slide rail 31, and the other end of the inner spring 50 is in contact with the shielding cover 29.

[0026] In this embodiment, when in use, the conveyor belt 1 can be driven to rotate first. When the conveyor belt 1 rotates, the sealed can 4 will be moved to the bottom of the rotating rod 12. When the sealed can 4 comes to the bottom of the rotating rod 12, the conveyor belt 1 will stop rotating under the preset PLC program (this is the prior art and will not be elaborated on). At this time, the milk tea pearls that have been produced and need to be packaged can be poured into the screening plate 10. After the milk tea pearls enter the screening plate 10, the driving motor 7 can be turned on to drive the rotating rod 12 to rotate slowly through the transmission rod 13. When the rotating rod 12 rotates, it will drive the rotating box 14 to rotate synchronously. During the rotation of the rotating box 14, the operator can energize the electromagnet 17 in the screening plate 10 to make the electromagnet 17 have magnetic force. When the rotating box 14 drives the vibrating magnet at the bottom of the air spray box 28 to intermittently come to the top of the electromagnet 17, the screening plate 10 will vibrate under the combined action of the intermittent magnetic force of the two and the elastic force of the vibrating spring 15. When the screening plate 10 vibrates, the milk tea pearls in the screening plate 10 will be screened, and those that meet the particle requirements will remain in the screening plate 10, otherwise those that do not meet the particle requirements will fall into the bottom cavity 16. By vibrating and screening the milk tea pearls, the particle requirements for the milk tea pearl packaging can be guaranteed.

[0027] Example 2: Please refer to Figure 1 - Fig.15 The cleaning mechanism is linked with the packaging and dehumidification mechanism. When packaging another batch of milk tea pearls, the screening plate 10 is cleaned. The cleaning mechanism includes a liquid storage tank 20 arranged on the rotating box 14. The interior of the liquid storage tank 20 is connected with a plurality of flow pipes 43. One end of the plurality of flow pipes 43 away from the liquid storage tank 20 is connected to the interior of the air spray box 28. The interiors of the plurality of flow pipes 43 are slidably connected with a slide plate 44. A centrifugal spring 48 is arranged at the end of the slide plate 44. The other end of the centrifugal spring 48 is connected to the outer wall of one of the plurality of flow pipes 43.

[0028] A plurality of through holes 47 corresponding to the circulation pipes 43 are provided on the slide plate 44, a plurality of connection boxes 45 are fixedly connected to the outer wall of the air spray box 28, a connection column 49 is slidably connected to the inner wall of the plurality of connection boxes 45, a pressure spring is sleeved on the connection column 49, a cleaning brush 42 is provided at the end of the connection column 49, a trigger magnet is provided at the end of the connection column 49 away from the cleaning brush 42, a plurality of compression-extension magnets 46 corresponding to the trigger magnets are provided on the slide plate 44, the compression-extension magnets 46 have the same magnetic poles as the trigger magnet, a bottom cavity 16 is provided on the mounting platform 5, the bottom cavity 16 is located directly below the screening plate 10, an electromagnet 17 is provided on the screening plate 10, and the electromagnet 17 has the same magnetic poles as the vibrating magnet.

[0029] In the present embodiment, since the milk tea pearls are made of cassava flour, they have a strong ability to absorb moisture, and after the milk tea pearls are steamed, they still contain some moisture. In order to dehumidify the milk tea pearls before packaging, the operator can turn on the cold fan 21 inside the rotating rod 12 to allow the cold fan 21 to rotate and blow cold air into the rotating rod 12. When the cold fan 21 rotates and blows air into the rotating rod 12, part of the cold air will be blown to the bottom of the rotating rod 12 through the circulation hole 24, and part of it will enter the inside of the air jet pipe 23. The cold air blown to the bottom of the rotating rod 12 will be blown into the sealed can 4 directly below it through the rotating rod 12, so that the sealed can 4 is also kept moist. When the rotating rod 12 drives the rotating box 14 to rotate, under the action of centrifugal force, the pushing member 25 will overcome the elastic force of the pressing spring 27 and move a short distance to the outside of the rotating box 14. When the pushing member 25 moves to the outside of the rotating box 14, it will lose the obstruction to one of the four air jet branch pipes 36. When the air jet pipe 23 no longer blocks one air jet branch pipe 36, the cold air entering the air jet pipe 23 according to the above principle will enter the air jet box 28 through one air jet branch pipe 36, and then blow to the screening plate 10 through the multiple air jet holes in the air jet box 28. When the air jet box 28 moves with the rotating box 14, the cold air will enter the air jet box 28 through the multiple air jet holes in the air jet box 28. When the pusher 25 rotates to spray air, the milk tea pearls in the conveyor belt 1 can be blown to remove moisture. When the pusher 25 moves toward the outside of the air jet pipe 23, it will first follow the bevel of the pressing magnet 39 to press the pressing magnet 39 toward the outside of the air jet pipe 23, and then come to the top of the pressing magnet 39. When the pressing magnet 39 overcomes the elastic force of the bottom spring 41 and moves toward the outside of the air jet pipe 23, it will be close to the distance between the pressing magnet 40 and the pressing magnet 40. At this time, under the action of the repulsive magnetic force, the pressing plate 38 will overcome the elastic force of the reset spring 35 to drive the multiple water absorption columns 37 to extend out of the rotating box 14. When the multiple water absorption columns 37 extend out of the rotating box 14 and slowly rotate with the rotating box 14, When rotating, it will contact the milk tea pearls in the screening plate 10. When the rotating box 14 contacts the milk tea pearls, it can not only cooperate with the vibrating screening plate 10 to overturn the milk tea pearls, but also the water absorption column 37 has strong water absorption. When it contacts the milk tea pearls, it can absorb some of the shallow moisture of the milk tea pearls, and cooperate with the air jet effect of the above principle to achieve the purpose of dehumidification (it should be noted that the water absorption column 37 contains hydrophilic groups, such as hydroxyl and carboxyl groups. There is a strong interactive attraction between these groups and water molecules. Therefore, when the water absorption column 37 contacts with the milk tea pearls made of tapioca flour, it can absorb the shallow moisture of the milk tea pearls).

[0030] After the air jet box 28 blows air into the screening plate 10 for a period of time, the operator can increase the power of the driving motor 7 to drive the rotating rod 12 to rotate rapidly. When the rotating rod 12 rotates rapidly, under the action of a large centrifugal force, the pushing member 25 will overcome the elastic force of the pressing spring 27 and be thrown toward the outer end of the air jet pipe 23. When the pushing member 25 is thrown toward the outer end of the air jet pipe 23, it will move along the pull rod 26 until it contacts the end protrusion of the pull rod 26, and drive the pull rod 26 to move toward the outside of the air jet pipe 23 through the end protrusion of the pull rod 26. When the pull rod 26 moves toward the outside of the air jet pipe 23, the pulling force on the wire rope 32 will be lost. At this time, under the action of the elastic force of the inner spring 50, the shielding cover 29 will move toward the middle of the flow hole 24 to block the flow hole 24. When the shielding covers 29 on both sides of the flow hole 24 move toward the flow hole When the convection hole 24 in the middle is closed and blocked, the wind blown by the cold fan 21 will not be blown into the sealed can 4 through the circulation hole 24, but will all enter the jet pipe 23. The pushing member 25 thrown to the outer end of the jet pipe 23 will lose the obstruction to all the jet branch pipes 36. At this time, the cold air blown into the jet pipe 23 will enter the jet box 28 through multiple jet branch pipes 36. The amount of cold air entering the jet box 28 through multiple jet branch pipes 36 will increase compared with before. By using a small wind in the early stage, the moisture on the surface of the pearls can be gently removed to avoid the rapid evaporation of moisture on the surface of the milk tea pearls due to excessive wind force, forming a hard shell or affecting the taste of the pearls. After most of the moisture on the surface of the milk tea pearls is removed, the wind force is increased in the later stage to accelerate the evaporation of moisture inside the pearls, so as to achieve a more thorough dehumidification effect and ensure the packaging effect of the milk tea pearls in the later stage.

[0031] After the milk tea pearls are completely dehumidified, the operator can stop the driving motor 7 and the cold fan 21, and then start the telescopic rod 8 to retract the telescopic rod 8, so that the entire rotating rod 12 moves upward, and the feed port 18 originally covered by the covering box 11 enters the screening plate 10. When the feed port 18 enters the screening plate 10, the pearls in the screening plate 10 will roll along its concave and inclined bottom to the middle point of the screening plate 10, and then enter the rotating rod 12 through the feed port 18, and finally enter the sealing can 4 located directly below the rotating rod 12 through the transportation of the rotating rod 12, so as to be transported. When the sealed can 4 is full, the operator can continue to drive the conveyor belt 1 to move, so that the sealed can 4 containing the pearls enters the packaging and sealing machine 3, and the packaging and sealing machine 3 performs packaging and sealing (this is the prior art and will not be elaborated in detail).

[0032] When it is necessary to pack milk tea pearls of different flavors, in order to prevent the milk tea pearls of different flavors from mixing with each other, the operator can start the drive motor 7 at high power to make the drive motor 7 rotate at high speed. When the drive motor 7 rotates at high speed, the operator can cut off the power to the electromagnet 17 to make the electromagnet 17 lose its magnetic force. After the electromagnet 17 loses its magnetic force, when the rotating box 14 rotates, the screening plate 10 will no longer vibrate. Under the action of the large centrifugal force generated by the high-speed rotation of the driving motor 7 driving the rotating rod 12, the slide plate 44 will overcome the elastic force of the centrifugal spring 48 and drive the through hole 47 to move into the circulation tube 43. When the through hole 47 moves into the circulation tube 43, the water that was originally blocked by the unopened part of the slide plate 44 from entering the rotating box 14 will be , will pass through the circulation pipe 43, and then enter the spray box 28 through the through hole 47. When there is water in the spray box 28, as the rotating box 14 rotates, the spray box 28 will spray the screening plate 10. When the slide plate 44 drives the through hole 47 to enter the circulation pipe 43, it will also drive the compression magnet 46 to enter the connection box 45. When the compression magnet 46 enters the connection box 45 and is located directly above the trigger magnet, under the action of the repulsive magnetic force, the connecting column 49 will overcome the pressure spring and drive the cleaning brush 42 to move downward and contact the screening plate 10. When the rotating box 14 rotates, the water dripping from the spray box 28 is used to brush the screening plate 10 to avoid the cross-flavor phenomenon when packaging different milk tea pearls.

[0033] It should be noted that the feed port 18 will enter the screening plate 10 only when the milk tea pearls are transported into the sealed can 4 . Under normal circumstances, the feed port 18 is covered by the covering box 11 . Therefore, when the rotating rod 12 blows air downward, cold air will not leak out through the feed port 18 .

[0034] It should also be noted that when the pusher 25 is thrown toward the end of the jet tube 23, the pusher 25 will lose contact with the pressing magnet 39. Under the elastic force of the return spring 35, the pressure plate 38 will drive the multiple water absorption columns 37 back to the inside of the rotating box 14. At this time, the operator can turn on the heater 19 to heat the inside of the rotating box 14 to evaporate the water absorbed by the water absorption columns 37, so that the dry water absorption columns 37 can be used next time.

[0035] It should also be noted that the elastic force of the bottom spring 41 is relatively small, and the force required to push the pressing magnet 39 to move toward the outside of the jet tube 23 is relatively small. Therefore, when the rotating box 14 stops rotating, under the elastic force of the pressing spring 27, the pushing member 25 can still first contact the pressing magnet 39 and then return to its original position. When the pressing magnet 39 returns to its original position, there is no pulling of the pushing member 25, and the pull rod 26 will also return to its original position under the elastic force of the extrusion spring 34. When the pull rod 26 returns to its original position, it will continue to pull the shielding cover 29 through the wire rope 32, so that it overcomes the elastic force of the inner spring 50 and moves to both sides of the flow hole 24, and no longer blocks the flow hole 24.

[0036] It should also be noted that the elastic force of the centrifugal spring 48 is greater than the elastic force of the compression spring 27. When the rotating rod 12 rotates rapidly to dehumidify the milk tea pearls, the centrifugal force generated is not sufficient to push the centrifugal spring 48 to compress. Therefore, the circulation tube 43 will not flow water into the air spray box 28, and a one-way valve is provided at the connecting interface between the circulation tube 43 and the air spray box 28, which only allows the circulation tube 43 to flow water into the air spray box 28. When the air spray box 28 sprays air outward, the air will not flow back into the circulation tube 43.
