Description

Technical Field

[0001] This invention relates to the field of pharmaceutical technology, and in particular to a capsule manufacturing machine. Background Technology

[0002] Capsule formulations have become a widely used form of pharmaceutical preparation due to their ability to reduce drug irritation, improve drug stability, and enhance bioavailability.

[0003] Currently, most small-batch capsule manufacturing machines on the market adopt a volumetric quantitative feeding solution. This solution features simple structure, low manufacturing cost, and convenient operation, meeting the basic needs of small-scale production. Specifically, the working principle of this type of capsule manufacturing machine is as follows: a rotatable stirring rod is set at the bottom of the storage tank, with several evenly arranged paddles on the stirring rod. The discharge port is located below the paddles. When the rotating rod completes one rotation stroke, the paddles push the material in the storage tank to complete one filling operation. However, this type of equipment has obvious limitations—it can only be used for single-dose capsule filling operations. If the filling dosage needs to be adjusted, the core components of the equipment must be disassembled, modified, or replaced, which is cumbersome and has low adjustment accuracy, making it difficult to meet the production needs of multiple specifications and small batches. Therefore, structural optimization and improvement are urgently needed.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems: Existing capsule manufacturing machines can only be used for single-dose capsule filling operations, and adjusting the filling dosage is difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a capsule pharmaceutical machine that solves the technical problem that existing capsule pharmaceutical machines can only be adapted to single-dose capsule filling operations and that the filling dosage is difficult to adjust.

[0006] Invention solution: This invention provides a capsule pharmaceutical machine, comprising a frame, a conveying device, a lower capsule shell placement device, an upper capsule shell placement device, and a feeding device; the conveying device is mounted on the frame; the lower capsule shell placement device is mounted on the frame, and the upper capsule shell placement device is mounted on the frame, located at the output end of the conveying device relative to the lower capsule shell placement device; the feeding device includes a hopper, a first motor, a hollow rotating shaft, a movable rod, and an adjusting component; the hopper is located between the upper and lower capsule shell placement devices; the first motor is mounted on the frame. The hollow rotating shaft is located below the hopper and has several fixed feeding components and several movable slots. The movable rod is located inside the hollow rotating shaft and is connected to a connecting column. The connecting column passes through the movable slots and is connected to a movable feeding component. An adjustable material cavity is formed between the movable feeding component and the fixed feeding component. A discharge hole is provided at the bottom of the hopper, and the discharge hole is smaller than the minimum volume of the adjustable material cavity. A reset device is provided between the movable feeding component and the fixed feeding component. The adjusting component is connected to the hollow rotating shaft and abuts against the movable feeding component.

[0007] Furthermore, the fixed feeder is provided with a plurality of first grooves and a plurality of first protrusions, the first grooves and the first protrusions being arranged at intervals; the movable feeder is provided with a plurality of second grooves and a plurality of second protrusions, the second grooves and the second protrusions being arranged at intervals; the first grooves and the second protrusions are adapted to be connected, and the first protrusions and the second grooves are adapted to be connected.

[0008] Furthermore, the length of the first protrusion is greater than the length of the second groove.

[0009] Furthermore, the reset device includes a limiting post and a spring member. The first protrusion is provided with a spring groove. The limiting post is fixedly installed in the second groove, and the spring member is sleeved on the limiting post, and its position corresponds to the spring groove.

[0010] Furthermore, the first protrusion is provided with a post hole, the post hole being positioned corresponding to the limiting post.

[0011] Furthermore, the adjusting component includes a disc and a polygonal cylinder, the disc being fixedly connected to the polygonal cylinder, and the polygonal cylinder being threadedly connected to the hollow rotating shaft.

[0012] Furthermore, the frame is provided with a bearing seat, which is connected to the hollow rotating shaft.

[0013] Furthermore, the output end of the conveying device is equipped with a collection box.

[0014] Beneficial effects: This invention provides a capsule pharmaceutical machine. In use, a lower capsule shell placement device places a lower capsule shell onto a conveying device. When the lower capsule shell moves directly below the feeding device, a first motor rotates one stroke, allowing material in the adjustable material chamber to enter the lower capsule shell. Then, when the lower capsule shell moves directly below the upper capsule shell placement device, the upper capsule shell is installed on top. When the filling dosage needs adjustment, the position of the adjusting component on the hollow rotating shaft is adjusted. This adjusting component can then adjust the position of the movable feeding component on the hollow rotating shaft, thereby adjusting the size of the adjustable material chamber and thus the filling dosage. This capsule pharmaceutical machine, by setting a fixed feeding component and a movable feeding component to cooperate in forming an adjustable material chamber, combined with the function of the adjusting component, allows for flexible adjustment of the material chamber volume without disassembling the core components of the equipment, thus achieving capsule filling with different dosages. This solves the problems of cumbersome dosage adjustment and low accuracy in existing equipment, adapting to the production needs of multiple specifications and small batches, and is especially suitable for small-batch, multi-variety pharmaceutical scenarios, meeting the technical development goal of "low dosage and high precision" in capsule filling.
