Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: In the prior art, a vibration mechanism is usually used to make the dispensing plate vibrate, and the dried fruit is fed in through the vibrating guide plate. However, in this process, it is difficult to accurately control the amount of material fed in, which may result in excessive material being fed in during the packaging process, affecting the accuracy of the packaging.
[0025] Therefore, in order to solve the problem of difficulty in accurately controlling the amount of dried fruit fed into existing packaging equipment during vibration feeding, which easily leads to excessive feeding of dried fruit at one time, and to improve the accuracy of packaging and metering, this utility model discloses a dried fruit metering and packaging mechanism. (See attached document.) Figures 1-3 The device includes a material distribution plate 1 and a housing 2 stacked in sequence. The material distribution plate 1 has a guide plate 5 on its edge. The outer wall of the housing 2 has a metering box 6. The upper and lower ends of the metering box 6 are respectively provided with an inlet 7 and an outlet 10. The inlet 7 is distributed in parallel below the guide plate 5. Specifically, the inner wall of the inlet 7 near the housing 2 has a horizontal protrusion 11. Below the protrusion 11, there is a feeding groove 12 that is vertically distributed along the inner wall of the metering box 6. The metering box 6 has a pre-storage plate 8 that fits against the protruding side of the protrusion 11. The end of the pre-storage plate 8 away from the protrusion 11 is provided with a second rotating shaft 14 for folding the pre-storage plate 8.
[0026] In this embodiment, refer to Figures 2-3In the initial state, the pre-storage plate 8 and the protrusion 11 are in contact with each other, so that the feed port 7 is closed. When the dried fruit needs to be packaged, the user can start the machine box 2, so that the vibration mechanism 18 inside the machine box 2 can start to vibrate the dispensing plate 1, so that the dispensing plate 1 can start to vibrate. The dried fruit on the dispensing plate 1 will roll onto the guide plate 5, and then the dried fruit on the guide plate 5 will roll toward the metering box 6. At this time, the second rotating shaft 14 can drive the pre-storage plate 8 to fold downward under the drive of the second driving member 13, so that a feeding port can be formed between the pre-storage plate 8 and the feeding trough 12. Then, due to the downward folding of the pre-storage plate 8, the dried fruit can smoothly enter the metering box 6 for weighing through the feeding port.
[0027] In the above process, the greater the downward folding angle of the pre-storage plate 8, the wider the diameter of the feeding port. Therefore, the user can control the size of the feeding port by adjusting the folding angle of the pre-storage plate 8, thereby adjusting the amount of dried fruit that can enter the metering box 6 through the feeding port each time. This extends the feeding speed of dried fruit, reduces the amount of dried fruit fed at one time, helps to avoid the situation of feeding too much at one time, and thus improves the efficiency of packaging and metering dried fruit.
[0028] In this embodiment, by passing the second rotating shaft 14 through the end of the pre-storage plate 8, the torque of the second rotating shaft 14 when rotating the pre-storage plate 8 can be extended, the folding speed of the pre-storage plate 8 can be slowed down, thereby further refining the control of the amount of dried fruit fed.
[0029] Example 2: Based on Example 1, in order to weigh the dried fruit entering the metering bin 6, refer to... Figure 3 The present invention also includes a weighing plate 15 for weighing dried fruit. Specifically, the weighing plate 15 is provided inside the weighing box 6 on the side near the discharge port 10, wherein the weighing plate 15 is provided with a weighing sensor.
[0030] In this embodiment, when dried fruit enters the metering hopper 6 through the feeding port, it falls onto the metering plate 15. At this time, the weighing sensor inside the metering plate 15 weighs the dried fruit and records the weight data. When the metering plate 15 accumulates dried fruit that reaches the preset weight threshold, the weighing sensor transmits a signal to the first drive member 9 and the second drive member 13, so that the metering plate 15 can be folded toward the discharge port 10 under the action of the first rotating shaft 16, and the dried fruit accumulated on the metering plate 15 is poured into the discharge port 10. When all the dried fruit on the metering plate 15 is poured out, the weight recorded by the weighing sensor will be reset to zero, and the signal will be transmitted to the first drive member 9 and the second drive member 13 again, so that the metering plate 15 can be reset, and the pre-storage plate 8 can be folded downwards again.
[0031] At the same time, the second rotating shaft 14 will also lift the pre-stored plate 8 to fit with the protrusion 11 under the drive of the second driving component 13, thereby closing the feed port 7, so that no new dried fruit will fall from the feed port when the metering plate 15 is folded to feed, further improving the control effect of the feeding amount.
[0032] In addition, when the pre-storage plate 8 is in contact with the protrusion 11, the guide plate 5 can continuously supply material to the metering box 6. At this time, the dried fruits will accumulate on the pre-storage plate 8. When the metering plate 15 is reset and the pre-storage plate 8 is folded down again, the accumulated dried fruits can pass through the discharge port again. In this way, the working continuity of the metering and dispensing mechanism can be improved.
[0033] In this embodiment, a first rotating shaft 16 for folding the measuring plate 15 is provided at the center line of the measuring plate 15. By providing the first rotating shaft 16 at the center line of the measuring plate 15, the torque of the first rotating shaft 16 when rotating the measuring plate 15 can be shortened, thereby improving the folding response speed of the measuring plate 15 and ensuring that the tilting action can be completed quickly and smoothly when the preset weight threshold is reached. In addition, it also helps to maintain the stability of the measuring plate 15 during the tilting process, avoids the dried fruit from scattering or getting stuck, and further improves the accuracy and efficiency of the dried fruit packaging.
[0034] In this embodiment, both the first driving component 9 and the second driving component 13 can be selected as motors or cylinders.
[0035] In this embodiment, the metering bin 6 is provided with a first driving member 9 and a second driving member 13 corresponding to the first rotating shaft 16 and the second rotating shaft 14 respectively, wherein the weighing sensor is connected to the first driving member 9;
[0036] Optionally, in order to enable the pre-storage plate 8 to be folded in conjunction with the metering plate 15, the weighing sensor is connected to the second drive component 13.
[0037] Example 3: Based on Example 1, in order to facilitate the smooth packaging of dried fruits, please refer to... Figure 4 The present invention also includes a boss 17 for dispensing dried fruit. Specifically, the top of the dispensing plate 1 is provided with a boss 17, wherein the guide plate 5 is arranged parallel to the bottom of the inclined side of the boss 17.
[0038] In this embodiment, by setting the boss 17, the boss 17 guides the dried fruit to slide naturally onto the guide plate 5 through its inclined side, which effectively reduces the jamming phenomenon of dried fruit in the process of dispensing, and further optimizes the flow path and dispensing efficiency of dried fruit.
[0039] Specifically, the housing 2 has a vibration mechanism 18 on the side facing the dispensing plate 1 to vibrate the dispensing plate 1. When the vibration mechanism 18 in the housing 2 is activated and vibrates the dispensing plate 1, the dried fruits are affected by the vibration and begin to roll on the dispensing plate 1. Due to the inclined design of the boss 17, the dried fruits can slide quickly and smoothly along this inclined surface to the guide plate 5 located below it. The guide plate 5 then continues to guide these dried fruits to roll towards the metering bin 6, ensuring the continuity and efficiency of the dried fruit dispensing.
[0040] Furthermore, the cooperation between the boss 17 and the guide plate 5 promotes the uniform distribution of dried fruit. Under vibration, the dried fruit can be evenly covered on the distribution plate 1, while the inclined side of the boss 17 ensures that the dried fruit can enter the guide plate 5 evenly and orderly, and then achieve accurate metering and packaging through the metering box 6. This process not only improves the accuracy of dried fruit packaging, but also significantly reduces the metering error caused by uneven accumulation of dried fruit.
[0041] Furthermore, the distribution plate 1 is provided with a top cover 3, wherein the boss 17 is sandwiched inside the top cover 3, and the top of the top cover 3 is provided with a receiving port 4 that is parallel to the boss 17. The receiving port 4 is parallel to the output end of the external elevator. By setting the top cover 3, the dried fruit on the surface of the distribution plate 1 can be prevented from rolling to the outside. In use, the dried fruit raw materials poured in from the external elevator can be received through the receiving port 4, so that these dried fruit raw materials can enter the distribution plate 1. Then, the vibration of the distribution plate 1 by the vibration mechanism 18 will cause them to enter the guide plate 5 along the boss 17.
[0042] In this embodiment, the vibration mechanism 18 includes a sleeve and a vibration rod. The sleeve is vertically fixed on the housing 2, and the vibration rod is movably inserted inside the sleeve. The housing 2 is equipped with a drive device for extending and retracting the vibration rod. One end of the vibration rod is attached to the material distribution plate 1, and the other end passes through the sleeve and is connected to the drive device inside the housing 2. The drive device can be a telescopic motor or a telescopic cylinder.
[0043] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
