Description

Technical Field

[0001] This utility model relates to the technical field of powder transportation equipment, specifically a novel powder supply device for powder capsules. Background Technology

[0002] In the preparation process of powdered soft capsules, a powder injection device is usually required in conjunction with two opposing extrusion rollers to complete the forming of the soft capsules. Patent application CN202321822612.X discloses a powder injection device for soft capsules. This device stores the powder through a powder storage mechanism and forms the soft capsules through a powder injection mechanism. However, in use, powder is typically added to the storage tank via a feeding pipe. This method, with its fixed powder addition position, easily leads to powder accumulation in one location, preventing the powder feeding screws in other locations from completing their feeding operations smoothly. Increasing the amount of powder added inevitably results in powder waste. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a novel powder supply device for powder-filled capsules.

[0004] The technical solution of this utility model is as follows:

[0005] A novel powder supply device for soft capsules includes a support and a material distribution mechanism that slides laterally on it. One end of the sliding path of the material distribution mechanism is also equipped with a powder supply mechanism. Through the docking of the material distribution mechanism and the powder supply mechanism, the powder can be received. By docking the material distribution mechanism with the powder supply device and cooperating with the lateral sliding, the powder can be added evenly along the sliding direction, thereby avoiding the accumulation of powder in a single position and ensuring that the powder injection and forming of soft capsules can be completed smoothly.

[0006] Specifically, the dispensing mechanism includes a horizontally sliding carriage with a vertically arranged cartridge on one side that can connect with the powder supply mechanism and receive the powder. The middle part of the cartridge is hinged to the carriage via a hinge block, and the axis of rotation is horizontal. A top plug is axially sliding inside the cartridge, and a dispensing motor is located at the bottom of the cartridge. The top plug is connected to the dispensing motor via a transmission rod. Based on the above structure, when the cartridge is vertically arranged, it can connect with the powder supply mechanism to receive the powder. By controlling the rotation of the hinge block and the sliding of the carriage, the powder can be added along the direction of carriage movement. By controlling the dispensing motor, the movement of the top plug can be controlled, ensuring that the powder can be added more evenly through the cartridge.

[0007] As described above, a novel powder supply device for powder-filled capsules includes a slide block comprising a slider and a connecting plate on one side; the connecting plate comprises a horizontal plate connected to the slider at one end, and a vertical plate provided on the lower side of the other end of the horizontal plate, wherein the hinge block is hinged to the lower side of the vertical plate. Based on this structure, the rotation range of the cartridge is increased, so that the powder in the cartridge can be smoothly added to the powder supply device under the action of the top stopper.

[0008] To ensure the rotational stability of the cartridge case under the action of the hinge block, two connecting plates are provided with opposite gaps, and the hinge block is located between the two connecting plates.

[0009] As described above, in a novel powder supply device for powder-filled capsules, the cartridge and the hinge block are detachably connected for easy disassembly and replacement.

[0010] In a preferred embodiment, the hinge block is provided with a through hole, through which the cartridge passes. An adjustment component is provided between the cartridge and the hinge block to adjust the height of the cartridge. Based on this structure, the docking height between the cartridge and the powder supply mechanism can be adjusted by the adjustment component to ensure that the receiving work can be completed smoothly. At the same time, the tilting position of the cartridge can be adjusted to ensure that the powder in the cartridge can be smoothly poured into the powder injection device.

[0011] As described above, in order to facilitate observation of the amount and state of the powder in the capsule, the capsule is made of a transparent or semi-transparent material.

[0012] As described above, a novel powder supply device for injecting powder capsules includes a powder storage cylinder with a powder outlet on its lower side and a feeding unit inside. To facilitate control of the feeding amount of the powder supply device and prevent excessive feeding from causing the powder to spill out of the cylinder, the feeding unit uses a spiral feeding method.

[0013] To ensure that the powder falls accurately into the cartridge under the action of the feeding unit and to prevent the powder from spilling, the minimum gap between the upper end of the cartridge and the powder outlet is no more than 3 cm.

[0014] To further ensure the accuracy of the powder receiving in the cartridge, the inner diameter of the powder outlet is smaller than the inner diameter of the cartridge.

[0015] The beneficial effects of this utility model are as follows: This utility model is a novel powder supply device for injection capsules. Through the docking of the dispensing mechanism and the powder supply mechanism, the powder receiving work can be completed. Through the docking of the dispensing mechanism and the powder injection device, combined with the lateral sliding, the powder can be added evenly along the sliding direction, thereby avoiding the accumulation of powder in a single position and ensuring that the powder injection and forming of soft capsules can be completed smoothly. When the cartridge is set vertically, it can dock with the powder supply mechanism to complete the powder receiving work. By controlling the rotation of the hinge block and the sliding of the slide, the powder can be added along the sliding direction. By controlling the dispensing motor, the movement of the top plug can be controlled, ensuring that the powder can be added more evenly through the cartridge. Attached Figure Description

[0024] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0025] Example

[0026] This embodiment provides a novel powder supply device for powder-injecting capsules. See [link / reference] Figure 1 and Figure 2The device includes a support 1 and a dispensing mechanism 2 and a powder supply mechanism 3 mounted thereon. The dispensing mechanism 2 is configured to connect with the powder supply mechanism 3 and the powder injection device (e.g., the powder storage tank of the powder injection device mentioned in the background art) to complete the receiving of the powder and the transfer of the powder to the powder injection device. The structure of the powder supply device (the above-mentioned novel powder supply device for powder injection capsules) will be described in detail below with reference to the accompanying drawings.

[0027] In this embodiment, combined with Figure 3 The support 1 includes a horizontally arranged slide rod 11, and the dispensing mechanism 2 is horizontally slidably arranged on the slide rod 11. One end of the slide rod is provided with a transverse motor that can drive the dispensing mechanism 2 to slide horizontally. The powder supply mechanism 3 is located at one end of the sliding path of the dispensing mechanism 2. Through the docking of the dispensing mechanism 2 and the powder supply mechanism 3, the powder receiving work can be completed. Through the docking of the dispensing mechanism 2 and the powder injection device, in conjunction with the horizontal sliding, the powder can be added evenly along the sliding direction, thereby avoiding the accumulation of powder in a single position and ensuring that the powder injection and forming of soft capsules can be completed smoothly.

[0028] The material distribution mechanism 2 includes a slide frame 21 that is laterally slidably disposed on the lower side of the slide rod. One side of the slide frame 21 is provided with a material distribution unit 22 that can connect with the powder supply mechanism 3 and the powder injection device to complete the powder transfer work.

[0029] Combination Figure 4 Specifically, the dispensing unit 22 includes a medicine cylinder 222 vertically disposed on one side of the slide 21, capable of docking with the powder supply mechanism 3 and receiving the medicine powder. The middle part of the medicine cylinder 222 is hinged to the slide 21 via a hinge block 221. The rotation axis of the hinge block 221 is horizontal and parallel to the sliding direction of the slide 21. A flipping motor 23 capable of driving the hinge block 221 to rotate is also provided on one side of the slide 21. A top plug 224 is axially slidably disposed inside the medicine cylinder 222, and the dispensing motor 223 is disposed at the bottom of the medicine cylinder 222. The transmission rod 225 is connected to the dispensing motor 223. Based on the above structure, when the medicine cartridge 222 is set vertically, it can dock with the powder supply mechanism 3 to complete the receiving of medicine powder. The rotation of the hinge block 221 is controlled by the flip motor 23, and the sliding of the slide 21 is controlled by the transverse motor. The medicine cartridge 222 can be driven to complete the supply and addition of medicine powder along the moving direction of the slide 21. By controlling the dispensing motor 223, the movement of the top plug 224 can be controlled, ensuring that the medicine cartridge 222 can complete the supply and addition of medicine powder more evenly.

[0030] To facilitate observation of the amount and state of the powder inside the cartridge 222, the cartridge 222 is made of a transparent or semi-transparent material.

[0031] In a preferred embodiment, the slide 21 includes a slider 211 slidably disposed on the lower side of the slide rod 11. A connecting plate 212 is provided on one side of the slider 211. The connecting plate 212 includes a horizontal plate connected to the slider 211 at one end and a vertical plate provided on the lower side of the other end of the horizontal plate. The vertical plate and the horizontal plate are coplanar and the plane in which they are located is vertical. The hinge block 221 is hinged to the lower side of the vertical plate. Based on this structure, the connecting plate 212 is designed in the shape of a "7", which increases the rotation range of the cartridge 222, so that the powder in the cartridge 222 can be smoothly added to the powder injection device under the action of the top stopper 224.

[0032] To ensure the rotational stability of the cartridge 222 under the action of the hinge block 221, two connecting plates 212 are provided with a gap between them, and the hinge block 221 is located between the two connecting plates 212.

[0033] As a further preferred embodiment, to facilitate the disassembly and replacement of the cartridge 222, the cartridge 222 is detachably connected to the hinge block 221.

[0034] Specifically, the hinge block 221 has a through hole through which the cartridge 222 passes. An adjustment assembly for adjusting the height of the cartridge 222 is provided between the cartridge 222 and the hinge block 221. The adjustment assembly includes a baffle 226 on the upper outer ring of the cartridge 222, which allows the cartridge 222 to be stably placed inside the hinge block 221. The adjustment assembly also includes an adjustment bolt 227 on the baffle 226, which allows it to press against the hinge block 221 and adjust the gap between the baffle 226 and the hinge block 221, thereby adjusting the height of the cartridge 222. Based on this structure, the adjustment assembly can adjust the docking height between the cartridge 222 and the powder supply mechanism 3 to ensure that it can smoothly complete the receiving work. At the same time, it can adjust the tilting position of the cartridge 222 to ensure that the powder inside the cartridge 222 can be smoothly poured into the powder injection device.

[0035] Regarding the structure of the powder supply mechanism 3, the bracket 1 further includes a fixed frame 12 located on the upper side of one end of the slide rod 11. The powder supply mechanism 3 includes a powder storage cylinder fixed to one side of the fixed frame 12, with a powder outlet on its lower side and a feeding unit inside. To facilitate control of the feeding amount of the powder supply device and prevent excessive feeding from causing the powder to spill out of the medicine cylinder 222, the feeding method of the feeding unit is screw feeding. Specifically, the feeding unit includes a feeding motor located on the upper side of the powder storage cylinder and a feeding screw vertically located inside the powder storage cylinder with its lower end inside the powder outlet. The feeding motor can drive the feeding screw to rotate, thus completing the powder feeding work.

[0036] To ensure that the powder falls accurately into the powder cylinder 222 under the action of the feeding unit and to prevent the powder from spilling, the minimum gap between the upper end of the powder cylinder 222 and the powder outlet is no more than 3cm, that is, the minimum gap between the lower end of the powder outlet and the powder cylinder 222 in the vertical state is no more than 3cm.

[0037] To further ensure the accuracy of the powder receiving by the cartridge 222, the inner diameter of the powder outlet is smaller than the inner diameter of the cartridge 222.
