Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging technology, and specifically to a filling metering device and method. Background Technology

[0002] When the existing sliding plate filling metering device is used to dispense material, the measuring cup containing the material needs to move a long distance to complete the dispensing. During the movement, the microparticles in the measuring cup may be subjected to compression and shearing. When encountering microparticles with large static electricity, uneven size, or uncoated microparticles, the breakage rate is very high. This makes it difficult to achieve the required drug filling accuracy and efficacy for treatment. In addition, the structure is relatively complex and occupies a lot of space due to the long movement distance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a filling metering device and method with simple structure, reduced material breakage and small stroke space.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A filling and metering device includes a discharge mechanism, a metering component, a discharge channel, and a feeding channel. The metering component is disposed within the discharge mechanism. The discharge mechanism can move up and down along the metering component to allow material in the discharge mechanism to enter the metering channel of the metering component. The discharge channel is located between the metering channel and the feeding channel, and the discharge channel can move horizontally to connect and disconnect with the metering channel and the feeding channel.

[0006] As a further improvement to the above technical solution:

[0007] The discharge mechanism includes a discharge hopper, a first material adjusting plate and a second material adjusting plate disposed in the discharge hopper. A receiving cavity is formed between the first material adjusting plate and the discharge hopper and between the second material adjusting plate and the discharge hopper. The first material adjusting plate and the second material adjusting plate abut against the two side walls of the metering component, respectively. A feed inlet is provided between the bottom of the discharge hopper and the first material adjusting plate and between the bottom of the discharge hopper and the second material adjusting plate.

[0008] The metering assembly includes an upper metering section, a lower metering section, an adjustment component, and a measuring component. The upper metering section and the lower metering section are sleeved together. The adjustment component is used to adjust the relative position of the upper metering section and the lower metering section to change the filling volume of the metering channel. The measuring component is used to measure the filling volume of the metering channel.

[0009] The adjusting component is an adjusting bolt, and the measuring component is a scale bolt. Both the adjusting bolt and the scale bolt are threadedly connected to the upper measuring part and can move relative to the lower measuring part.

[0010] The top of the discharge mechanism is connected to a distribution box, and the distribution box is provided with a uniform material channel that communicates with each receiving chamber.

[0011] Both the first and second material adjusting plates are connected to adjusting components for adjusting the size of the feed inlet. The adjusting components include adjusting blocks and connecting parts. The adjusting blocks are connected to the corresponding material adjusting plates. The adjusting blocks have oblong holes. The connecting parts pass through the oblong holes and are connected to the dispensing box.

[0012] The filling and metering device also includes a feeding hopper, which is connected to the dispensing box via a discharge pipe, and the discharge pipe is equipped with a discharge control mechanism.

[0013] The discharge mechanism is connected to a lifting cam drive, and the discharge channel is connected to a moving cam drive. Both the lifting cam drive and the moving cam drive are located on the same side of the discharge mechanism.

[0014] The discharge mechanism is equipped with a vibrator and a material sensor.

[0015] A filling measurement method includes the following steps:

[0016] S1. The discharge mechanism rises to allow the material inside the discharge mechanism to enter the metering channel of the metering component;

[0017] S2. The discharge mechanism descends, and the material drop channel moves horizontally to connect with the metering channel and the unloading channel;

[0018] S3. The material is fed from the metering channel through the feeding channel and the unloading channel in sequence.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The filling and metering device disclosed in this invention includes a discharge mechanism that is filled with material and can move vertically. When the discharge mechanism rises, the material enters the metering channel of the metering component. The metering channel measures the filling amount of material. Once the metering channel is full, the discharge mechanism descends, and no more material enters the metering channel. Then, the discharge channel moves horizontally to the left, connecting with the metering channel and the discharge channel at both ends. At this point, the material in the metering channel can freely fall through the discharge channel for filling. The discharge channel then moves to the right, disconnecting from the metering and discharge channels at both ends. This ensures that the feeding of the metering channel is not affected, and since there is no material in the metering channel during the rightward movement, the discharge channel will not contact the material, thus avoiding compression and shearing. The metering component of this filling device does not require horizontal movement, and the horizontal movement stroke of the discharge channel is very small, reducing the compression and shearing of the material in the metering channel, decreasing the possibility of material breakage and static electricity, improving filling accuracy, and minimizing the space occupied due to the small stroke.

[0021] The filling and metering method disclosed in this invention involves the following steps: The discharge mechanism rises, and the metering component is positioned lower relative to the discharge mechanism, allowing material to enter the metering channel. Then, the discharge mechanism descends, and the metering component is positioned higher relative to the discharge mechanism, stopping the material from entering the metering channel. Next, the discharge channel moves horizontally to the left, connecting its two ends to the metering channel and the discharge channel respectively. At this point, material in the metering channel can freely fall through the discharge channel and discharge channel for filling. After filling is complete, the discharge channel moves to the right, disconnecting its two ends from the metering channel and discharge channel. This process does not affect the feeding into the metering channel, and since there is no material in the metering channel during the rightward movement, the discharge channel will not contact the material, preventing compression and shearing, reducing the possibility of material breakage and static electricity, and improving filling accuracy.

[0035] Example 1

[0036] Figures 1 to 8 An embodiment of the present invention is shown. The filling and metering device of this embodiment includes a discharge mechanism 1, a metering component 2, a discharge channel 3, and a discharge channel 4. The metering component 2 is disposed inside the discharge mechanism 1. The discharge mechanism 1 can move up and down along the metering component 2 so that the material in the discharge mechanism 1 enters the metering channel 21 of the metering component 2. The discharge channel 3 is located between the metering channel 21 and the discharge channel 4, and the discharge channel 3 can move horizontally to connect and disconnect with the metering channel 21 and the discharge channel 4.

[0037] The filling and metering device has a discharge mechanism 1 containing material that can be raised and lowered. When the discharge mechanism 1 rises, the material in the discharge mechanism 1 enters the metering channel 21 of the metering component 2. The metering channel 21 can measure the filling amount of material. After the metering channel 21 is full, the discharge mechanism 1 descends, and no more material continues to enter the metering channel 21. Then, the dropping channel 3 moves horizontally to the left, and its two ends connect with the metering channel 21 and the discharge channel 4 respectively. At this time, the material in the metering channel 21 can be discharged and filled by free falling through the dropping channel 3 and the discharge channel 4. The dropping channel 3 moves to the right, and its two ends disconnect from the metering channel 21 and the discharge channel 4. This will not affect the feeding of the metering channel 21. During the process of the dropping channel 3 moving to the right, there is no material in the metering channel 21, so the dropping channel 3 will not come into contact with the material and will not cause compression or shearing to the material. The metering component 2 of the metering filling device does not need to move horizontally, and the horizontal movement stroke of the material discharge channel 3 is very small, which reduces the compression and shearing of the material in the metering channel 21, reduces the possibility of material breakage and static electricity, improves the filling accuracy, and occupies little stroke space due to the small stroke.

[0038] In this embodiment, the discharge mechanism 1 includes a discharge hopper 12, a first material adjusting plate 13 and a second material adjusting plate 14 disposed within the discharge hopper 12. A receiving chamber 15 is formed between the first material adjusting plate 13 and the discharge hopper 12, and between the second material adjusting plate 14 and the discharge hopper 12. The first material adjusting plate 13 and the second material adjusting plate 14 respectively abut against the side walls of the metering component 2. An inlet 11 is provided between the bottom of the discharge hopper 12 and the first material adjusting plate 13 and the second material adjusting plate 14. Material is stored in the receiving chambers 15 on both sides. Since the inlets 11 are located between the bottom of the discharge hopper 12 and the first material adjusting plate 13, and between the bottom of the discharge hopper 12 and the second material adjusting plate 14, when the discharge hopper 12 is not raised, the inlets 11 are blocked by the side walls of the metering component 2, preventing material from entering the metering channel 21. During feeding, the discharge hopper 12 rises until the height of the inlet 11 is higher than that of the metering component 2. Material from the receiving chambers 15 on both sides can then be fed into the metering channel 21 through the inlet 11. After feeding is complete, the discharge hopper 12 descends until the height of the inlet 11 is lower than that of the metering component 2, at which point feeding stops. Preferably, the discharge hopper 12 is a transparent hopper, facilitating observation of the material entering and exiting the hopper.

[0039] In this embodiment, the metering component 2 includes an upper metering section 22, a lower metering section 23, an adjusting element 24, and a measuring element 25. The upper metering section 22 and the lower metering section 23 are sleeved together. The adjusting element 24 is used to adjust the relative position of the upper metering section 22 and the lower metering section 23 to change the filling volume of the metering channel 21. The measuring element 25 is used to measure the filling volume of the metering channel 21. The filling volume of the metering channel 21 can be pre-measured to a set amount by the measuring element 25. Then, the distance between the upper metering section 22 and the lower metering section 23 can be adjusted by the adjusting element 24 until the set amount requirement of the measuring element 25 is met, thereby increasing or decreasing the filling volume of the metering channel 21 to meet different filling volume requirements.

[0040] In this embodiment, the adjusting component 24 is an adjusting bolt, and the measuring component 25 is a scale bolt. Both the adjusting bolt and the scale bolt are threadedly connected to the upper measuring part 22 and can move relative to the lower measuring part 23. First, the upper measuring part 22 is adjusted to the set scale using the scale bolt, and then it is fixed by adjusting the adjusting bolt.

[0041] In this embodiment, a material distribution box 8 is connected to the top of the discharge mechanism 1. The material distribution box 8 is provided with a material leveling channel that communicates with each receiving chamber 15. The material distribution box 8 distributes and levels the material to the receiving chambers 15 on both sides through the material leveling channel (not shown in the figure).

[0042] In this embodiment, both the first material adjusting plate 13 and the second material adjusting plate 14 are connected to adjusting components 7 for adjusting the size of the feed inlet 11. The adjusting component 7 includes an adjusting block 71 and a connecting member 72. The adjusting block 71 is connected to the corresponding material adjusting plate, and the adjusting block 71 has a slotted hole 711. The connecting member 72 passes through the slotted hole 711 and connects to the distributing box 8. By adjusting the connection position between the corresponding slotted hole 711 and the distributing box 8, the distance between the first material adjusting plate 13 and the second material adjusting plate 14 and the bottom of the discharge hopper 12 is finely adjusted, thereby adjusting the size of the feed inlet 11 and achieving the purpose of adjusting the feeding speed into the metering channel 21.

[0043] In this embodiment, the filling and metering device also includes a feeding hopper 9, which is connected to the dispensing box 8 via a discharge pipe 10. The discharge pipe 10 is equipped with a discharge control mechanism 101. Material is fed into the dispensing box 8 through the feeding hopper 9 and the discharge pipe 10. The discharge control mechanism 101 can control the opening and closing of the discharge pipe 10.

[0044] In this embodiment, the discharge mechanism 1 is connected to a lifting cam drive 5, and the discharge channel 3 is connected to a moving cam drive 6. Both the lifting cam drive 5 and the moving cam drive 6 are located on the same side of the discharge mechanism 1, saving space.

[0045] In this embodiment, the discharge mechanism 1 is equipped with a vibrator 16 and a material sensor 17. The vibrator 16 vibrates the material in the discharge hopper 12, breaking up electrostatic bridging, so that the material in the discharge hopper 12 can be fed into the metering channel 21 in a timely and stable manner. The material sensor 17 can sense and detect the amount of material in the receiving chamber 15, so that the amount of material in the receiving chamber 15 is kept within a reasonable range, reducing the filling difference.

[0046] Example 2

[0047] The filling and metering method of this embodiment includes the following steps:

[0048] S1. The discharge mechanism 1 rises so that the material in the discharge mechanism 1 enters the metering channel 21 of the metering component 2.

[0049] S2. The discharge mechanism 1 descends, and the discharge channel 3 moves horizontally to connect with the metering channel 21 and the discharge channel 4.

[0050] S3. The material is fed from metering channel 21 through dropping channel 3 and unloading channel 4.

[0051] In this filling and metering method, the discharge mechanism 1 rises, and the metering component 2 is positioned lower relative to the discharge mechanism 1, allowing the material in the discharge mechanism 1 to enter the metering channel 21. Then, the discharge mechanism 1 descends, and the metering component 2 is positioned higher relative to the discharge mechanism 1, stopping the material in the discharge mechanism 1 from entering the metering channel 21. Next, the dropping channel 3 moves horizontally to the left, connecting its two ends to the metering channel 21 and the discharge channel 4 respectively. At this point, the material in the metering channel 21 can fall freely through the dropping channel 3 and the discharge channel 4 for filling. After the material is discharged, the dropping channel 3 moves to the right, disconnecting its two ends from the metering channel 21 and the discharge channel 4. This method does not affect the feeding of the metering channel 21, and since there is no material in the metering channel 21 during the movement of the dropping channel 3 to the right, the dropping channel 3 will not come into contact with the material, thus avoiding compression and shearing, reducing the possibility of material breakage and static electricity, and improving the filling accuracy.

[0052] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
