[0013] 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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: In this technical solution, a capsule filling structure with adjustable filling volume includes a fixing plate 1, a support plate 2 installed on the side wall of the fixing plate 1, a placement groove 3 opened on the upper wall of the support plate 2, a capsule shell 4 placed in the placement groove 3, and a metering mechanism 5 arranged above the support plate 2. See attached document Figure 1The middle part of the support plate 2 is provided with a plate that can slide outward, and the placement groove 3 is provided on the plate to facilitate the removal of the capsule shell 4 after filling. The quantitative mechanism 5 includes a composite plate 51, threaded holes 52, fixing bolts 53 and through grooves 54. Multiple composite plates 51 are provided and are stacked on top of each other. Threaded holes 52 are provided on both the left and right side walls of the composite plate 51. Fixing bolts 53 are screwed into the threaded holes 52. Through grooves 54 are provided on the upper wall of the composite plate 51. There are two through grooves 54 in total. The through grooves 54 are located above the support plate 2. See attached document Figure 1 The support plate 2 is also provided with a groove for limiting the position, and the metering mechanism 5 can be inserted into the groove to ensure that the positioning mechanism 5 does not move back and forth during the sliding process. A storage trough 6 is installed on the side wall of the fixing plate 1. The storage trough 6 can slide up and down on the side wall of the fixing plate 1. There are two storage troughs 6 in total. The two storage troughs 6 are respectively located on the left and right sides above the composite plate 51. The storage trough 6 is filled with medicine powder. The storage tank 6 can slide up and down to facilitate the addition or reduction of the composite plate 51. At the same time, it can also ensure that after the number of composite plates 51 changes, the position of the storage tank 6 can be adjusted to ensure that the storage tank 6 can fit tightly against the upper wall of the uppermost composite plate 51 to prevent the powder from spilling. The connection structure between storage tank 6 and fixing plate 1 in this article can be found in the appendix. Figure 4 The storage tank 6 has a support plate on its side wall and a bolt on its top. The fixing plate 1 has a sliding groove, and the support plate passes through the fixing plate 1 through the sliding groove. At the same time, the back side of the fixing plate 1 has a screw hole. The position of the storage tank 6 is fixed by the cooperation of the bolt and the screw hole. In this technical solution, the fixing plate 1 serves as the basic load-bearing component of the entire filling structure, providing a stable installation benchmark for other components such as the support plate 2 and the metering mechanism 5, ensuring that the positions of each component are relatively fixed and avoiding the impact of structural shaking on filling accuracy; the support plate 2 is connected to the fixing plate 1 by welding, and its core function is to provide a placement platform for the capsule shell 4. The size of the placement groove 3 is precisely matched with the outer diameter of the capsule shell 4, which can stably limit the position of the capsule shell 4, preventing the capsule shell 4 from shifting or tipping over during the filling process, and ensuring that the powder can fall accurately into the capsule; The stacking design of multiple composite plates 51 is key to adjusting the filling volume: the thickness of a single composite plate 51 is fixed, and the more composite plates 51 are stacked, the greater the total depth of the "quantitative cavity" formed by aligning the slots 54 of all composite plates 51, and the larger the volume, thus increasing the amount of powder to be filled in a single batch. Conversely, reducing the number of composite plates 51 reduces the filling volume. There is no need to replace the entire quantitative mold; adjustments can be made flexibly simply by adding or removing composite plates 51. The threaded hole 52, in conjunction with the fixing bolt 53, can secure the stacked composite plates 51 into a single unit, preventing misalignment of the composite plates 51 during filling and thus ensuring a stable powder capacity. Two through slots 54 are located below the two storage slots 6 respectively. The top rods 11 on both sides can press the powder in the storage slots 6 into the through slots 54 on both sides. Then, the stacked plate 51 is pushed to one side by the electric telescopic rod 12, so that the through slot 54 on one side moves above the placement slot 3. At this time, the top rod 11 is moved down by the electric push rod 9 again, so that the powder compacted in the through slot 54 is sent into the capsule shell 4 to complete the filling.

[0015] In some technical solutions, the lower walls on both sides of the composite plate 51 are equipped with locking blocks 7, and the upper wall of the composite plate 51 is provided with a slot 8 that cooperates with the locking blocks 7, and the locking blocks 7 can be inserted into the slot 8.

[0016] In this technical solution, the locking block 7 and the locking slot 8 constitute the positioning structure of the stacked plate 51. When multiple stacked plates 51 are stacked, the locking block 7 of the upper stacked plate 51 can be accurately inserted into the locking slot 8 of the lower stacked plate 51, restricting the relative displacement of the stacked plates 51 in the horizontal and vertical directions, ensuring that the through slots 54 of all stacked plates 51 are completely aligned, and avoiding the occurrence of "misalignment gaps" in the metering cavity formed by the through slots 54 due to the misalignment of the through slots 54. If the through slots 54 are misaligned, the powder may get stuck in the gap, which will not only cause waste, but also cause the actual filling volume to deviate from the set value. This structure further improves the filling accuracy of the metering mechanism 5.

[0017] In some technical solutions, an electrically controlled push rod 9 is installed on the upper end of the side wall of the fixed plate 1, a horizontal plate 10 is installed on the output end of the electrically controlled push rod 9, and a top rod 11 is installed on the lower wall of the horizontal plate 10. There are three top rods 11 in total, and the positions of the three top rods 11 correspond to those of the through groove 54.

[0018] In this technical solution, the electrically controlled push rod 9 is powered on and its output end pushes the horizontal plate 10 downward, causing the three push rods 11 to move down synchronously. The two edge push rods 11 are located above the storage tank 6 and are responsible for pressing the powder in the storage tank 6 into the through groove 54. The middle push rod 11 is longer than the push rods 11 on both sides and is responsible for pushing the powder in the through groove 54 into the corresponding capsule shell 4 below. At the same time, the pushing force and stroke of the electrically controlled push rod 9 can be adjusted by an external control system to ensure that the powder pushing force is moderate. This control system can be a PLC or a separate control switch can be set up so that the operator can manually control the push and retraction of the electrically controlled push rod 9.

[0019] In some technical solutions, an electrically controlled telescopic rod 12 is installed on the side wall of the fixed plate 1. The electrically controlled telescopic rod 12 is electrically connected to an external power source, and the output end of the electrically controlled telescopic rod 12 is connected to the side wall of the composite plate 51.

[0020] In this technical solution, the electrically controlled telescopic rod 12 is responsible for driving the quantitative mechanism 5 to slide left and right, so as to adjust the position of the through groove 54. When filling the medicine, the two through grooves 54 are respectively set below the two storage grooves 6. When filling is completed and filling is carried out, the electrically controlled telescopic rod 12 is pushed out or retracted, so that the two through grooves 54 move to the top of the placement groove 3 in sequence, and then the medicine powder is pressed into the capsule shell 4 by the top rod 11. The electrically controlled telescopic rod 12 is the same as the electrically controlled push rod 9. It can be controlled by an external PLC or by a separate control switch for manual control by the operator. In this paper, an insertion rod is provided at the output end of the electric telescopic rod 12, and an insertion ring is provided on the side wall of the composite plate 51. The electric telescopic rod 12 is connected to the composite plate 51 through the cooperation between the insertion rod and the insertion ring. Its electrically controlled telescopic rod 12 is selected to have an adjustable extension distance, so that it can be adjusted according to the distance between the through slot 54 and the placement slot 3.

[0021] In some technical solutions, a collection groove 13 is installed on the side wall of the fixing plate 1, and the collection groove 13 is located below the support plate 2.

[0022] In this technical solution, the collection tank 13 is responsible for collecting the spilled powder to avoid waste.

[0023] In some technical solutions, a sealing ring 14 is fitted to the lower wall of the storage tank 6, and the sealing ring 14 is fitted to the upper wall of the composite plate 51.

[0024] In this technical solution, the sealing ring 14 can improve the sealing performance of the contact position between the storage tank 6 and the upper wall of the composite plate 51, and prevent a large amount of powder from spilling out.

[0025] Working principle: First, determine the number of stacked plates 51 according to the filling specifications of the target capsule. Then, after the stacked plates are positioned by the locking block 7 and the locking groove 8, the multiple stacked plates 51 are fastened together by the fixing bolt 53 through the threaded hole 52 to form a metering cavity of corresponding volume. This metering cavity refers to the overall space after the through groove 54 is aligned. Then, the assembled quantitative mechanism 5 is placed between the support plate 2 and the storage tank 6, and connected to the electrically controlled telescopic rod 12. Then, the position of the storage tank 6 is adjusted so that it fits tightly against the upper wall of the uppermost composite plate 51 and is fixed. Then, the medicine powder can be put into the storage tank 6. At this time, the through groove 54 on the composite plate 51 corresponds to the position of the edge push rod 11. The operator can control the electric push rod 9 to push it down, causing the push rod 11 to move down and press the powder into the through groove 54. After pressing, the electric push rod 9 resets. Then, the operator controls the electric telescopic rod 12 to push it out, moving one of the two through grooves 54 above the placement groove 3. Then, the electric push rod 9 is activated again, and the powder is pressed into the capsule shell 4 through the middle push rod 11. After filling is completed, the electric push rod 9 resets. At this time, the operator can pull the plate in the middle of the support plate 2 outward, take out the filled capsule shell 4, put in a new capsule shell, and then put the plate back in place. At this time, the operator controls the electric telescopic rod 12 to retract, moving the other through groove 54 above the placement groove 3 for refilling.
