[0002] In the fields of pharmaceuticals, food, chemicals, and agriculture, the production of powder products often faces problems such as uneven mixing of multi-component materials, low efficiency of manual filling, insufficient metering accuracy, and dust pollution. Traditional production methods are difficult to meet the needs of large-scale, refined, and clean production.

[0003] In the prior art, such as Chinese Patent Publication No. CN222611421U, a powder mixing and filling device is disclosed. The bottom end of the stirring assembly is equipped with a scraping component for scraping off methylcyclopropene powder that has caked on the bottom of the mixing tank cavity. The filling box cavity is equipped with a filling assembly for removing the methylcyclopropene powder from the filling box. The mounting box cavity is equipped with a first connecting assembly for engaging with the filling assembly, and second connecting assemblies are provided above and below the first connecting assembly for engaging with it. By driving the rotating shaft with a motor, not only can three sets of stirring blades stir the methylcyclopropene powder in the mixing tank, but the scraper can also scrape off the methylcyclopropene powder from the bottom of the mixing tank cavity. Simultaneously, the rotating shaft rotates, causing the spiral blades to move the methylcyclopropene powder falling from discharge port one to the right, and then filling the methylcyclopropene powder from discharge port two along the discharge pipe into the filling bottle.

[0004] Although the powder mixing and filling device in the aforementioned patent can not only drive three sets of stirring blades to stir the methylcyclopropene powder in the mixing tank, but also drive the scraper to scrape the bottom of the mixing tank cavity, and simultaneously rotate the rotating shaft, causing the spiral blades to drive the methylcyclopropene powder falling from the discharge port one to move to the right, and causing the methylcyclopropene powder to be filled into the filling bottle from the discharge port two along the discharge pipe, the size of the opening used for filling and discharging is fixed. It can usually only fill bags with larger openings, which has great limitations and poor practicality. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the opening size for filling and discharging in the existing technology is fixed, which usually can only fill bags with larger openings, resulting in great limitations and poor practicality. Therefore, a powder mixing and filling device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a powder mixing and filling device, comprising a discharge cylinder, a mixing tank installed at the top of the discharge cylinder, a connecting pipe fixed at the bottom of the mixing tank, the bottom of the connecting pipe being fixed to the discharge cylinder, a control valve installed on the outer wall of the connecting pipe, a second motor installed at one end of the discharge cylinder, the output end of the second motor passing through one side of the discharge cylinder and fixed with an auger, a discharge module snapped into the open end of the discharge cylinder, connecting plates fixed on both sides of one end of the discharge module, a body fixed at the top of the discharge cylinder, clamping plates provided on both sides of the bottom end of the body, locking blocks fixed at opposite ends of the two clamping plates, the two locking blocks respectively snapping into the two connecting plates, and a drive structure provided inside the body for driving the two clamping plates to move in opposite directions.

Both ends of the outer wall of the bidirectional screw are threaded with movable plates. Both ends of the two movable plates are slidably connected with limit posts. The bottom ends of the two movable plates are fixed with connecting blocks. The bottom ends of the two connecting blocks penetrate the machine body and are respectively fixed to two clamping plates.

[0008] Preferably, a top cover is bolted to the top of the discharge cylinder, a first motor is mounted on the top of the top cover, the output end of the first motor passes through the bottom end of the top cover and is fixed with a stirring shaft, and multiple stirring rods are fixed on the outer wall of the stirring shaft.

[0009] Preferably, the end of the bidirectional screw away from the third motor is rotatably connected to the machine body, and both ends of the limiting post are fixed to the machine body.

[0010] Preferably, the bottom of the machine body is provided with movable grooves on both sides that match the connecting block.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1-4 As shown, this utility model provides a powder mixing and filling device, including a discharge cylinder 1, a mixing tank 3 installed at the top of the discharge cylinder 1, a connecting pipe 2 fixed at the bottom of the mixing tank 3, the bottom of the connecting pipe 2 being fixed to the discharge cylinder 1, a control valve 4 installed on the outer wall of the connecting pipe 2, a second motor 9 installed at one end of the discharge cylinder 1, the output end of the second motor 9 passing through one side of the discharge cylinder 1 and fixed with an auger 10, a discharge module 11 snapped into the open end of the discharge cylinder 1, connecting plates 12 fixed on both sides of one end of the discharge module 11, a body 13 fixed at the top of the discharge cylinder 1, clamping plates 15 provided on both sides of the bottom end of the body 13, a locking block 16 fixed at the opposite end of the two clamping plates 15, the two locking blocks 16 respectively snapped into the two connecting plates 12, and a driving structure 14 for driving the two clamping plates 15 to move in opposite directions or opposite directions inside the body 13.

[0022] The overall effect of Embodiment 1 is as follows: powder is poured into the discharge cylinder 1 through the opening at the top; the mixed powder is then introduced into the discharge cylinder 1 through the opening of the control valve 4 via the connecting pipe 2. The second motor 9 drives the auger 10 to rotate, thus transmitting the mixed powder. The transmitted powder is then discharged through the discharge module 11 for filling. The discharge module 11 is designed and can be rotated and replaced with different models according to actual needs. The discharge module 11 can assemble the opening of the discharge cylinder 1 to adjust the size of the discharge opening. The model of the discharge module 11 has been modified to be suitable for small bag filling. Through the operation of the drive structure 14, the two clamping plates 15 can be driven to move in opposite directions. When the two clamping plates 15 move in opposite directions, they can drive the two locking blocks 16 to engage with the two connecting plates 12, thereby quickly installing the discharge module 11. When the two clamping plates 15 move in opposite directions, they can drive the two locking blocks 16 to disengage from the two connecting plates 12, thereby quickly disassembling the discharge module 11. This makes it more practical and reduces the downtime of the entire mechanism when replacing the discharge module 11.

[0023] Example 2, as Figure 1-4As shown, the drive structure 14 includes a third motor 1401 mounted on the inner wall of the machine body 13. A bidirectional screw 1402 is fixed to the output end of the third motor 1401. Moving plates 1403 are threaded to both ends of the outer wall of the bidirectional screw 1402. Limiting posts 1404 are slidably connected to both ends of the two moving plates 1403. Connecting blocks 1405 are fixed to the bottom ends of the two moving plates 1403. The bottom ends of the two connecting blocks 1405 penetrate the machine body 13 and are respectively fixed to two clamping plates 15. A top cover 5 is bolted to the top of the discharge cylinder 1. A first motor 6 is mounted on the top of the top cover 5. The output end of the first motor 6 passes through the bottom end of the top cover 5 and is fixed with a stirring shaft 7. Multiple stirring rods 8 are fixed on the outer wall of the stirring shaft 7. The end of the bidirectional screw 1402 away from the third motor 1401 is rotatably connected to the machine body 13. Both ends of the limiting column 1404 are fixed to the machine body 13. The bottom ends of the machine body 13 are provided with moving grooves 17 that match the connecting block 1405. Both ends of the discharge cylinder 1 are fixed with mounting plates 18. Multiple mounting holes 19 are provided in both mounting plates 18. Multiple support columns 20 are fixed to the bottom end of the stirring tank 3. The bottom ends of the support columns 20 are fixed to the discharge cylinder 1.

[0024] The overall effect of Embodiment 2 is that the operation of the third motor 1401 drives the bidirectional screw 1402 to rotate, causing the two moving plates 1403 to move towards or away from each other under the limitation of the limiting post 1404. This, in turn, causes the two clamping plates 15 connected by the two connecting blocks 1405 to move towards or away from each other. When the two clamping plates 15 move towards each other, they can engage the two connecting plates 12, thus enabling quick installation of the discharge module 11. Conversely, when the two clamping plates 15 move in opposite directions, causing the two locking blocks 16 to disengage from the two connecting plates 12, the discharge module 11 can be quickly disassembled, thus improving practicality. This device is powerful and reduces downtime when replacing the discharge module 11, making it more practical. The operation of the first motor 6 drives the stirring shaft 7 to rotate, which in turn drives the stirring rod 8 to rotate, thus mixing the powder in the mixing tank 3. The installation plate 18 and the installation hole 19 allow for the installation of the discharge cylinder 1. This device can be fed through the top opening of the mixing tank 3, or a corresponding feeding port can be opened in the top cover 5 according to actual needs. The first motor 6, the second motor 9, the third motor 1401 and the control valve 4 of this device are all electrically connected to an external controller.

[0025] Working Principle: In use, powder or other substances are poured into the discharge cylinder 1 through the opening at the top. The first motor 6 drives the stirring shaft 7 to rotate, which in turn drives the stirring rod 8, mixing the powder or other substances in the mixing tank 3. The mixed powder then enters the discharge cylinder 1 through the connecting pipe 2 via the opening of the control valve 4. The second motor 9 drives the auger 10 to rotate, thus transmitting the mixed powder. The transmitted powder is discharged through the discharge module 11 for filling. The discharge module 11 is designed and can be rotated and replaced with different models according to actual needs. The discharge module 11 can assemble the opening of the discharge cylinder 1 to maximize its discharge width. The small size can be changed according to the model of the discharge module 11, which is suitable for small bag filling. The operation of the third motor 1401 can drive the bidirectional screw 1402 to rotate, so that the two moving plates 1403 can move towards or away from each other under the limit of the limit post 1404. This causes the two clamping plates 15 connected by the two connecting blocks 1405 to move towards or away from each other. When the two clamping plates 15 move towards each other, they can engage the two connecting plates 12, thus enabling the quick installation of the discharge module 11. When the two clamping plates 15 move in opposite directions, they can disengage the two clamping blocks 16 from the two connecting plates 12, enabling the quick disassembly of the discharge module 11. This makes it more practical and reduces the downtime of the whole mechanism when replacing the discharge module 11.

[0026] The wiring diagrams of the first motor 6, the second motor 9, the third motor 1401, and the control valve 4 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the first motor 6, the second motor 9, the third motor 1401, and the control valve 4 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
