Description

Technical Field

[0001] The utility model relates to the technical field of particle packaging equipment, in particular to a quantitative charging device for granules. Background Art

[0002] Granular medications are a commonly used oral solid dosage form. During the packaging process, the dosage of each bag is strictly controlled. If the dosage is unstable, patients will not be able to accurately calculate the dosage when taking the medicine, which may lead to serious medical accidents. Patent publication number "CN218142258U" discloses an automatic packaging device for Chinese medicine granules. The device uses a first lifting unit to drive a metering unit upward. The bottom end of the loading unit is forced upward and forms a cone, pushing the internal Chinese medicine granules outward. This allows the metering unit to hold the desired dosage of Chinese medicine granules. A second valve unit cooperates with the second lifting unit to release the Chinese medicine granules from the metering unit, thus achieving the desired packaging. However, with this method, only one loading can be performed at a time, which is inefficient. Moreover, when the Chinese medicine granules flow from the storage section into the loading section and then into the quantitative section, the loading section is easily filled. When the quantitative section is filled, a large amount of granules remain in the storage section. When the quantitative section is driven to rise by the first lifting section, the upper end of the quantitative section is difficult to move above the highest point of the granules in the storage section. In other words, the upper end of the quantitative section may still be located inside the granules in the storage section, and granules are still accumulated on the upper side of the quantitative section. Even through vibration, only the granules in the loading section can be leveled, and the granules at the upper end of the quantitative section cannot be kept flat with the end of the quantitative section. When the granules in the quantitative section are discharged, the granules on the upper side of the quantitative section will also enter the quantitative section and be discharged, resulting in inaccurate granule dosage. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a granule quantitative charging device to solve the problems in the prior art of low charging efficiency and difficulty in ensuring that the top of the quantitative part can push out of the horizontal surface of the granules after rising, thereby making it difficult to ensure the accuracy of the dosage of the granules.

[0004] In order to solve the above technical problems, the utility model provides a quantitative charging device for granules, comprising a hopper with a first valve at the outlet, a distribution box is provided below the hopper, a first push plate is provided in the distribution box and can be moved along the length direction of the distribution box by a first cylinder, a receiving box is provided on the side of the distribution box away from the first cylinder, an opening is provided between the receiving box and the distribution box that matches the height of the first push plate, a plurality of distribution holes are provided on the bottom wall of the distribution box, a quantitative part is provided below the distribution hole, the quantitative part is connected to the distribution hole by an elastic part, and the plurality of The lower end of the quantitative part is fixedly extended through a movable plate, and the movable plate is connected to the distribution box through a lifting mechanism. The distribution box is also provided with a second push plate that can be moved along the width direction of the distribution box by a second cylinder. The bottom height of the second push plate is adapted to the top height of the quantitative part when it is raised, and the bottom height of the first push plate is lower than the bottom height of the second push plate. A discharge plate is also movably provided under the movable plate, and a discharge hole with a second valve corresponding to the quantitative part is provided on the discharge plate, and an adjustment part for adjusting the dosage is provided on the upper side of the discharge hole.

[0005] Furthermore, the discharge plate is provided with at least two groups of adjustment holes, the movable plate is provided with an adjustment screw matched with the adjustment holes, and the upper end of the adjustment screw passes through the adjustment hole and is connected to the positioning nut.

[0006] Furthermore, the bottom of the regulating portion is rotatably connected to the inner wall of the discharge hole, and the upper portion of the regulating portion is threadedly engaged with the lower portion of the quantitative portion.

[0007] Furthermore, a rubber pad is provided at the bottom of the second push plate.

[0008] Furthermore, sliding grooves are provided on both side walls of the material distribution box in the length direction, and sliding blocks that cooperate with the sliding grooves are provided on both sides of the first push plate.

[0009] Furthermore, a discharge port with a third valve is provided at the lower end of the material receiving box.

[0010] The beneficial effects of the present invention are as follows: the hopper is used to store granules, the first valve is configured to control the opening or closing of the hopper outlet to control whether to discharge the granules, and the distribution box below the hopper cooperates with the metering unit to quantitatively load the granules. The first push plate in the distribution box is configured to flatten the granules in the distribution box after the granules enter the distribution box, and push the excess granules into the receiving box through the opening, ensuring that the lower side of the receiving box is filled with granules and the upper side is empty. The space on the upper side is used to ensure that the top of the metering unit can protrude above the horizontal plane of the granules in the distribution box after it moves upward. The bottom of the distribution box is provided with a number of distribution holes so that multiple quantitative loadings can be carried out simultaneously. The distribution holes are connected to the quantitative part by an elastic part. Since the quantitative part is fixed to the movable plate, when the lifting mechanism drives the movable plate to move upward toward the distribution box, the upper end of the quantitative part moves upward through the distribution holes and squeezes the particles in the distribution box to the surrounding areas. The upper end of the quantitative part drives the elastic part to deform into a cone with a high middle and low sides until the upper end of the quantitative part moves to the upper side of the horizontal plane of the particles in the distribution box. The bottom height of the second push plate in the distribution box is adapted to the height of the top of the quantitative part. When the second push plate moves, the bottom scrapes across the top of the quantitative part to flatten the granules on the top of the quantitative part after the quantitative part rises, avoid particle accumulation, and achieve precise quantification. The bottom height of the first push plate is lower than the bottom height of the second push plate, ensuring that the horizontal height of the granules in the distribution box is lower than the top height after the quantitative part is raised, thereby ensuring that the top of the quantitative part can be pushed out from the granules. A discharge plate is movably provided below the movable plate, so that the discharge plate can move relative to the movable plate, and the distance between the discharge plate and the movable plate can be adjusted, and then the granule dosage can be adjusted by cooperating with the regulating part and the quantitative part. When the discharge plate moves up, the capacity of the regulating part and the quantitative part decreases, and the dosage decreases accordingly. When the discharge plate moves down, the capacity of the regulating part and the quantitative part increases, and the dosage increases accordingly. In summary, by adopting the present invention, the dosage of granules can be adjusted as needed, and multiple quantitative parts can be loaded at one time. Furthermore, by setting the first push plate, the granules in the distribution box can be kept at a certain horizontal height and the upper space of the inner cavity can be empty. The rising height of the quantitative part is controlled by the lifting mechanism, so that the top of the quantitative part can be pushed out from the granules in the distribution box, and then the granules on the top of the quantitative part can be flattened by the second push plate, thereby realizing precise quantitative loading of granules.

DETAILED DESCRIPTION

[0015] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0016] Reference Figures 1 to 2 The utility model provides a quantitative charging device for granules, including a hopper 2 with a first valve at the outlet, the hopper 2 is used to store granules, and the first valve is set to control the opening or closing of the outlet of the hopper 2 to control whether to discharge the granules.

[0017] A distribution box 3 is located below the hopper 2 and is connected to the hopper 2 via an outlet. A first push plate 32 is installed within the distribution box 3, driven by a first cylinder 31 and movable along the length of the distribution box 3. The first cylinder 31 drives the first push plate 32 to move back and forth along the length of the distribution box 3. Furthermore, two side walls of the distribution box 3 are provided with chutes 38, and two sides of the first push plate 32 are provided with sliders that cooperate with the chutes 38. The cooperation between the sliders and the chutes 38 ensures the stability of the first push plate 32, thereby ensuring that the level of the granules in the distribution box 3 remains consistent.

[0018] A receiving box 33 is provided on the side of the material distribution box 3 away from the first cylinder 31. Furthermore, a discharge port 331 with a third valve is provided at the lower end of the material distribution box 33 for discharging the granules in the receiving box 33 and circulating the material. An opening 34 is provided between the receiving box 33 and the material distribution box 3, which matches the bottom height of the first push plate 32. After the granules enter the material distribution box 3, the first push plate 32 flattens the granules in the material distribution box 3 and pushes the excess granules into the material distribution box 33 through the opening 34, ensuring that the lower side of the inner cavity of the material distribution box 33 is piled with granules, while the upper side is empty. The space on the upper side is used to ensure that the top of the quantitative part 4 can protrude above the horizontal plane where the granules in the material distribution box 3 are located after it moves upward.

[0019] The bottom wall of the dispensing box 3 is provided with a plurality of dispensing holes 35 so as to carry out multiple quantitative loadings at the same time. A quantitative portion 4 is provided below the dispensing hole 35. Specifically, the quantitative portion 4 is a cylindrical structure with upper and lower openings 34. Of course, it can also be set as a square structure with upper and lower openings 34. The quantitative portion 4 is connected to the dispensing hole 35 by an elastic portion 5. Preferably, the elastic portion 5 is made of elastic silicone material. The upper end of the elastic portion 5 is fixed to the dispensing hole 35, and the lower end is fixed to the top of the quantitative portion 4. The lower ends of several of the quantitative portions 4 are fixedly passed through a movable plate 6, and the movable plate 6 is connected to the dispensing box 3 through a lifting mechanism 7. Specifically, the lifting mechanism 7 includes two telescopic cylinders, which are symmetrically arranged on the movable plate 6 to improve the stability of the movable plate 6. One end of the telescopic cylinder is fixed to the movable plate 6, and the other end is fixed to the dispensing box 3. At this time, when the lifting mechanism 7 drives the movable plate 6 to move upward toward the distribution box 3, the upper end of the quantitative part 4 moves upward through the distribution hole 35 and squeezes the particles in the distribution box 3 to the surrounding areas. The upper end of the quantitative part 4 drives the elastic part 5 to deform into a cone with a high middle and low surrounding areas until the upper end of the quantitative part 4 moves to the upper side of the horizontal plane of the particles in the distribution box 3.

[0020] The dispensing box 3 is also provided with a second push plate 37 driven by a second cylinder 36 and movable along the width direction of the dispensing box 3. A rubber pad 371 is provided at the bottom of the second push plate 37 to reduce wear between the second push plate 37 and the top of the quantitative section 4, thereby increasing its service life. The bottom height of the second push plate 37 is adapted to the top height of the quantitative section 4 when it is raised. The bottom height of the first push plate 32 is lower than the bottom height of the second push plate 37, ensuring that the horizontal height of the granules in the dispensing box 3 is lower than the top height of the quantitative section 4 after it is raised, thereby ensuring that the top of the quantitative section 4 can be ejected from the granules. When the quantitative section 4 moves upward, the second push plate 37 moves in the width direction of the dispensing box 3 under the action of the second cylinder 36, and the bottom scrapes across the top of the quantitative section 4, thereby flattening the granules on the top of the quantitative section 4 after the quantitative section 4 rises, avoiding granule accumulation and achieving precise quantitative determination.

[0021] A discharge plate 8 is also movably disposed below the movable plate 6. The discharge plate 8 is movable relative to the movable plate 6. A discharge hole 81 with a second valve is provided on the discharge plate 8, corresponding to the dosing unit 4. An adjustment portion 9 is provided above the discharge hole 81, which cooperates with the dosing unit 4 to adjust the dosage. Specifically, the adjustment portion 9 can be configured as a cylindrical or square structure with openings 34 at both ends adapted to the dosing unit 4. The adjustment portion 9 and the dosing unit 4 form a common inner cavity for accommodating the granules.

[0022] Furthermore, the discharge plate 8 is provided with at least two sets of adjustment holes 82, and the movable plate 6 is provided with an adjustment screw 62 that engages with the adjustment holes 82. The lower end of the adjustment screw 62 passes through the adjustment holes 82 and is connected to the positioning nut 63. By adjusting the position of the positioning nut 63 on the adjustment screw 62, the distance between the discharge plate 8 and the movable plate 6 can be adjusted, thereby adjusting the dosage. When the discharge plate 8 moves upward, the capacity of the adjustment portion 9 and the dosing portion 4 decreases, and the dosage is correspondingly reduced. When the discharge plate 8 moves downward, the capacity of the adjustment portion 9 and the dosing portion 4 increases, and the dosage is correspondingly increased. Preferably, the adjustment portion 9 and the dosing portion 4 are both configured as cylindrical structures, with the bottom of the adjustment portion 9 rotatably connected to the inner wall of the discharge hole 81, and the upper portion of the adjustment portion 9 threadedly engaged with the lower portion of the dosing portion 4. During use, the adjustment portion 9 is first rotated to adjust the dosage and then locked with the locking nut. This not only allows the dosage of the granules to be adjusted by rotating the adjustment portion 9, but also ensures a stable connection between the dosing portion 4 and the adjustment portion 9.
