[0027] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Figure 1 It is a schematic structural diagram of the tea box turning and discharging device provided by the embodiment of the present application; Figure 2 It is a schematic structural diagram of the fixing frame in the embodiment of the present application; Figure 3 It is a schematic structural diagram of the bottom frame in the embodiment of the present application;

[0029] Figure 4 It is a multi-view schematic structural diagram of the bottom frame in the embodiment of the present application; Figure 5 In the embodiment of the present application Figure 3 The enlarged view of part A therein.

[0030] The embodiment of the present application provides a tea box turning and discharging device, as Figure 1 shown. The tea box turning and discharging device may include a fixing frame 1, a bottom frame 2, an outer box 3, a receiving belt line 4, a safety lifting door 5, a lifting transition mechanism, a turning mechanism, and a knocking mechanism;

[0031] Among them, the bottom frame 2 is arranged on one side of the fixing frame 1 in the first direction; the outer box 3 is fixedly installed on the top surface of the bottom frame 2; the receiving belt line 4 is arranged at the opening at one end of the outer box 3 away from the fixing frame 1; the safety lifting door 5 is arranged at the opening at one end where the outer box 3 and the fixing frame 1 are close to each other; the lifting transition mechanism is arranged on the fixing frame 1, and the lifting transition mechanism provides a driving force in the height direction of the fixing frame 1; the turning mechanism is arranged on the top surface of the bottom frame 2 and partially passes through and is located outside the outer box 3, and the turning mechanism provides a driving force for the turning of the wooden box 18.

[0032] Specifically, the fixing frame 1, the bottom frame 2, and the receiving conveyor belt 4 are sequentially connected in the first direction X, and the first direction X can specifically be the transmission direction of the receiving conveyor belt 4 in the production line. The bottom frame 2 is used to support and install the flipping mechanism; the outer box 3 is fixedly installed on the top surface of the bottom frame 2, and the outer box 3 can isolate the components on the bottom frame 2 from the outside world for flipping and discharging; the receiving conveyor belt 4 is arranged at the opening at one end of the outer box 3 away from the fixing frame 1, and the receiving conveyor belt 4 can discharge and convey the tea leaves for feeding and processing; the safety lifting door 5 is arranged at the opening at one end of the outer box 3 close to the fixing frame 1 and can cover one end of the outer box 3 to prevent the tea leaves from leaking out.

[0033] Please refer to Figure 2 for reference. The lifting and transition mechanism is arranged on the fixing frame 1. The lifting and transition mechanism can provide a driving force in the height direction of the fixing frame 1. It can be understood that the fixing frame 1 is usually vertically placed. Thus, the height direction of the fixing frame 1 is the vertical direction. Correspondingly, the wooden box 18 can be moved in the vertical direction through this lifting and transition mechanism, that is, the wooden box 18 is lifted to the top of the fixing frame 1 for subsequent flipping and discharging.

[0034] Please refer to Figures 3 - 4 for reference. The flipping mechanism is arranged on the top surface of the bottom frame 2. The flipping mechanism can provide a flipping driving force for the wooden box 18. After the wooden box 18 is lifted to the top of the fixing frame 1, the wooden box 18 can be flipped through this flipping mechanism to pour out the tea leaves in the wooden box 18 so that the tea leaves enter the receiving conveyor belt 4 for transmission.

[0035] Furthermore, in an exemplary embodiment, the box flipping and discharging device may further include a knocking mechanism. The knocking mechanism is arranged on the top surface of the bottom frame 2 and is located inside the outer box 3 and is connected to the flipping mechanism. Please refer to Figures 4 - 5 for reference. The knocking mechanism is arranged on the top surface of the bottom frame 2. The knocking mechanism can knock on the wooden box 18 during the flipping process to prevent the tea leaves from remaining in the wooden box 18.

[0036] More specifically, the wooden box 18 rises through the lifting and transition mechanism. When the in-place condition is triggered, the wooden box 18 enters the outer box 3; when the next in-place condition is triggered, the safety lifting door 5 closes; when the next in-place condition is triggered, the tea leaves are flipped into the receiving conveyor belt 4 through the flipping mechanism and transported to the subsequent production line; when the next in-place condition is triggered, the flipping is completed, and then it is reversed, and the wooden box 18 is flipped back to the horizontal state; when the next in-place condition is triggered, the safety lifting door 5 opens; when the next in-place condition is triggered, it descends to the low point through the lifting and transition mechanism and runs to the outer roller line of the elevator. The lifting, transition, and flipping mechanisms are completed at this point.

[0037] Please continue to refer to Figure 2Referring to, in an exemplary embodiment, the lifting transition mechanism may include a lifting bracket 6, two transition chain lines 7, a counterweight 8, a mounting bracket 9, two sprockets 10, a lifting motor 11, and two chains 12; wherein, the lifting bracket 6 is slidably engaged with the fixed bracket 1 and has a sliding freedom degree in the height direction of the fixed bracket 1; the two transition chain lines 7 are arranged on the top surface of the lifting bracket 6; the counterweight 8 is slidably mounted on the inner wall of one side of the fixed bracket 1 in the second direction Y, and the second direction Y intersects with the first direction X; the mounting bracket 9 is fixedly mounted on the top surface of the fixed bracket 1 near one side of the counterweight 8; the two sprockets 10 are rotatably mounted on the top surface of the mounting bracket 9; the lifting motor 11 is fixedly mounted on the top surface of the mounting bracket 9, and the output end of the lifting motor 11 is fixedly connected to the two sprockets 10; the two chains 12 are respectively arranged on the outer surfaces of the two sprockets 10, and the two ends of the chain 12 are respectively fixedly connected to the lifting bracket 6 and the counterweight 8.

[0038] Specifically, the second direction Y intersects with the first direction X. In the case where the fixed bracket 1 is a regular square structure, the second direction Y may specifically be perpendicular to the first direction X. For example, if the first direction is the width direction of the fixed bracket 1, then the second direction may be the length direction of the fixed bracket 1, and the counterweight is equivalent to being arranged at one end of the fixed bracket 1 in the width direction, so that the lifting transition mechanism lifts the wooden box 18 to the top of the fixed bracket 1 on one side in the width direction of the fixed bracket 1. Of course, this is only an exemplary illustration and does not constitute a limitation to the present application. In other embodiments, the lifting transition mechanism may also have other arrangement manners.

[0039] Combined with Figure 1 and Figure 2 , a detection photoelectric sensor may be installed on the transition chain line 7. When the wooden box 18 enters the transition chain line 7, the lifting motor 11 rotates to pull the wooden box 18 to move inward. After the wooden box 18 is in place, the sensor detects the in-place state, and the lifting motor 11 starts to operate. The chain 12 is used to pull the lifting bracket 6 upward, and the wooden box 18 starts to rise slowly. At the same time, the counterweight 8 descends, always keeping a balanced state with the wooden box 18. Due to the downward gravity of the counterweight 8, this lifting mechanism always maintains a smooth lifting and lowering.

[0040] It should be noted that in this exemplary embodiment, the wooden box 18 and the tea leaves in the wooden box 18 can be weighed before the wooden box 18 enters the transition chain line 7, and the wooden box 18 is weighed again when it exits, so as to calculate the weight of each box of tea leaves. By weighing the wooden box 18 and the tea leaf raw materials in it when entering and exiting, the weight of each box of tea leaf raw materials can be accurately grasped, so that it can be ensured that the subsequent production can achieve precise control of the production process according to the net weight of the tea leaf raw materials.

[0041] Please continue to combine Figure 3 , Figure 4Referring to the drawings, in an exemplary embodiment, the flipping mechanism may include a flipping reduction motor 13, a flipping shaft 14, a driving gear 15, a flipping gear 16, a peripheral bracket 17, a wooden box limiting frame 19, two safety locking mechanisms 20, and two transition chain lines II 22. Among them, the flipping reduction motor 13 is fixedly installed on the side wall of the outer box 3; the flipping shaft 14 is rotatably installed on the top surface of the chassis 2; the driving gear 15 is fixedly installed at the output end of the flipping reduction motor 13; the flipping gear 16 is fixedly installed at one end of the flipping shaft 14, and the flipping gear 16 meshes with the driving gear 15; the peripheral bracket 17 is fixedly installed on the outer wall of the flipping shaft 14, and the wooden box 18 is arranged inside the peripheral bracket 17; the wooden box limiting frame 19 is arranged at the open end of the wooden box 18; the two safety locking mechanisms 20 are symmetrically arranged on the peripheral bracket 17, and the safety locking mechanism 20 is adapted to the wooden box limiting frame 19; the two transition chain lines II 22 are symmetrically arranged on the inner bottom wall of the peripheral bracket 17.

[0042] Specifically, the whole flipping mechanism is installed on the ground by expansion screws, and the upper edge is installed below the receiving belt line 4. When the wooden box 18 runs to a position at the same height as the transition chain line II 22 on the flipping mechanism through the lifting mechanism, the photoelectric sensor detects that it is in place, and the flipping reduction motor 13 rotates to move the wooden box 18 further towards the transition chain line II 22 inside the flipping mechanism. After the wooden box 18 is in place, the travel sensor (installed inside the receiving belt line 4) detects that it is in place, the safety lifting door 5 closes, and the safety locking mechanism 20 moves downward to pull the wooden box limiting frame 19 downward to clamp the wooden box 18, so that the wooden box 18 cannot move forward, backward, left, or right during the flipping process, ensuring a smooth flip. The flipping reduction motor 13 drives the wooden box 18 and the peripheral bracket 17 to flip together through the transmission of the driving gear 15 and the flipping gear 16. Because the torque and reduction ratio of the flipping reduction motor 13 and the reducer are relatively large, there is a three-fold safety factor, which can make the whole flipping gentle and stable. After flipping in place, the travel switch sensor is triggered, and the system defaults that the flipping is completed. The flipping reduction motor 13 starts to reverse and flips to the horizontal state, and the flipping process is completed. The working principles and connection methods of the transition chain line I 7, the transition chain line II 22, and the safety locking mechanism 20 are all existing mature technologies and will not be elaborated here.

[0043] Further, a blanking frame 21 is arranged at the open end of the wooden box 18, and the blanking frame 21 is trapezoidal.

[0044] Specifically, when the tea in the wooden box 18 is poured out, it can be poured out through the blanking frame 21 onto the receiving belt line 4. The trapezoidal shape of the blanking frame 21 can limit the tea during pouring, preventing the tea from falling outside the receiving belt line 4, thereby reducing waste.

[0045] In some embodiments, the diameter of the driving gear 15 is smaller than the diameter of the flipping gear 16. In this way, it can ensure that the rotation speed of the flipping shaft 14 is easier to control.

[0046] As described above, the box-tilting and material-dumping device may further include a knocking mechanism. Please refer to Figures 4 - 5 for details. In an exemplary embodiment, the knocking mechanism may include a rotating shaft 23, a plurality of knocking rods 24, a plurality of knocking heads 25, a torsion spring 26, and a driving mechanism. Among them, the rotating shaft 23 is rotatably installed on the side wall of the outer peripheral bracket 17 near one end of the tilting shaft 14; the plurality of knocking rods 24 are symmetrically and fixedly sleeved on the outer surface wall of the rotating shaft 23 in a linear array; the plurality of knocking heads 25 are respectively fixedly installed at one ends of the plurality of knocking rods 24 away from the rotating shaft 23; the torsion spring 26 is sleeved on one end of the rotating shaft 23, and both ends of the torsion spring 26 are fixedly connected to the rotating shaft 23 and the outer peripheral bracket 17 respectively; the driving mechanism is arranged on one side of the outer peripheral bracket 17.

[0047] Specifically, during the flipping process of the outer peripheral bracket 17 and the wooden box 18, the driving mechanism can drive the rotating shaft 23 to rotate reciprocally. During the reciprocal rotation of the rotating shaft 23, the outer surface wall of the wooden box 18 can be knocked by the knocking rods 24 and the knocking heads 25, so that the tea leaves in the wooden box 18 are vibrated, avoiding the situation of incomplete discharging caused by accumulation.

[0048] Furthermore, limiting plates 27 adapted to the knocking rods 24 are symmetrically and fixedly installed on the inner side wall of the outer peripheral bracket 17.

[0049] Specifically, the limiting plates 27 can limit the rotation of the knocking rods 24, and can avoid the knocking rods 24 from rotating too much.

[0050] Even further, a rubber pad is sleeved on the knocking head 25.

[0051] Specifically, the sleeved rubber can avoid damaging the wooden box 18 when the knocking head 25 knocks it.

[0052] It can be understood that during the process of tilting and dumping the stored tea raw materials, the tea raw materials enter the production line from the warehouse, and mostly rely on manual transportation and adjustment. Moreover, since a certain amount of tea leaves will remain in the container during the tea dumping process, it not only increases the difficulty of subsequent cleaning, but also causes waste of tea raw materials. In this embodiment, the knocking mechanism provided solves the problem of tea leaf residue during the dumping of tea raw materials, and improves the production efficiency of the subsequent process at the same time.

[0053] In some embodiments, the driving mechanism may include a fixed arc plate 28, several groups of teeth 29, a transmission shaft 30, a half gear 31, two driven wheels 32, and a synchronous belt 33. Among them, the fixed arc plate 28 is fixedly installed on the top surface of the chassis 2 on the side away from the turnover reduction motor 13. Several groups of teeth 29 are fixedly installed on the inner side wall of the fixed arc plate 28 in an annular array. The transmission shaft 30 is rotatably installed on the inner bottom wall of the outer bracket 17. The half gear 31 is fixedly installed at one end of the transmission shaft 30, and the half gear 31 meshes with the teeth 29. The two driven wheels 32 are respectively fixedly sleeved on one end of the transmission shaft 30 away from the half gear 31 and one end of the rotating shaft 23 away from the torsion spring 26. The synchronous belt 33 is sleeved on the two driven wheels 32.

[0054] Specifically, during the process of the outer bracket 17 turning over, since the fixed arc plate 28 is connected to the chassis 2, it is in a fixed state. When the outer bracket 17 rotates, it can drive the half gear 31 to rotate along the turning shaft 14. And the half gear 31 meshes with the teeth 29 on the fixed arc plate 28, and there is a certain gap between several groups of teeth 29. The rotating shaft 23 can be reset by the torsion spring 26. Therefore, when the half gear 31 rotates along the turning shaft 14, it can rotate itself through the teeth 29 and drive the rotating shaft 23 to rotate through the driven wheel 32 and the synchronous belt 33. When the rotating shaft 23 rotates, it can move away from the wooden box 18. When the half gear 31 is separated from the teeth 29, at this time, under the action of the torsion spring 26, the rotating shaft 23 can reverse, and thus the wooden box 18 can be knocked by the knocking rod 24 and the knocking head 25.

[0055] Further, the fixed arc plate 28 is coaxially arranged with the turning shaft 14.

[0056] Specifically, the coaxial arrangement of the fixed arc plate 28 and the turning shaft 14 ensures that the half gear 31 can rotate along the inner side wall of the fixed arc plate 28.

[0057] In some embodiments, the tea box turnover and discharging device may further include a control unit, and the control unit is respectively connected to the lifting and transition mechanism, the turnover mechanism, and the knocking mechanism.

[0058] Exemplarily, the control unit can be a programmable control unit or a DCS control unit, which realizes the real-time automatic control of the lifting and transition mechanism, the turnover mechanism, and the knocking mechanism, reduces manual operation, and improves the automation degree of tea box turnover and discharging.

[0059] The tea turning and discharging device proposed in the embodiment of the present application has all its parts connected to the control unit, reducing manual operation, filling the gap in the automated connection of tea from the semi-finished tea warehouse to the production line, reducing time and labor costs. Moreover, the whole device is a closed device with a dust-proof cover, and the dust-proof cover is connected to the dust removal system to collect the dust generated during production, improving the working environment in the workshop, meeting the environmental protection requirements. At the same time, the overall production efficiency is high, capable of turning 300 kg of tea at a time and can be turned once every 180 s, which is sufficient to meet the needs of modern production.

[0060] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly.
