[0037] A moving structure 500 comprising a first pushing rod 510 for pushing the blocking part 410 to block the opening at the bottom of the metering cylinder 310 and a second pushing rod 520 for pushing the handle part 420 to open the opening at the bottom of the metering cylinder 310.
[0038] The feeding hopper 100 is located at the top of the powder packaging machine and has a funnel-shaped structure with a large opening at the upper end for manually or automatically pouring powder into it. The lower end of the feeding hopper 100 is connected to the buffer bin 200, and the powder flows smoothly into the buffer bin 200 after entering the feeding hopper 100. The buffer bin 200 is a container with a certain volume, which can be cylindrical or cuboid in shape, used to temporarily store the powder fed from the feeding hopper 100. The bottom of the buffer bin 200 is provided with an opening connected to the metering assembly 300, and the powder will flow into the metering assembly 300 through the opening.

The upper and lower ends of the metering cylinders 310 are through, the upper end is connected to the buffer bin 200, and the lower end is matched with the baffle plate 400. The number of baffle plates 400 corresponds to the number of metering cylinders 310. Each baffle plate 400 includes a blocking part 410 and a handle part 420. The shape of the blocking part 410 matches the opening at the lower end of the metering cylinder 310, blocking the powder in the metering cylinder 310. By moving the handle part 420, the position of the baffle plate 400 can be adjusted to achieve the feeding of the powder. When the powder needs to be fed, the powder in the metering cylinder 310 can flow out smoothly by moving the handle part 420; when the feeding needs to be stopped, the lower opening of the metering cylinder 310 can be closed by moving the blocking part 410 to block the outflow of the powder.
[0039] The design of the baffle 400 matches the measuring cylinder 310, and through the accurate control of the moving structure 500, powder can be quickly and accurately put, and the packaging efficiency is improved. Through a plurality of measuring cylinders 310, powder of a preset weight can be weighed and reserved in advance, and in the production process, the powder can be quickly put into at the moment when it is needed, without waiting for temporary weighing and preparation of the powder, so that the production cycle is effectively shortened, and the production efficiency is significantly improved.
[0040] The working principle of the utility model is as follows:
[0041] Firstly, the operator pours the powder into the feeding hopper 100, and the powder enters the buffer bin 200 under the guidance of the feeding hopper 100. The powder in the buffer bin 200 flows into the measuring cylinder 310 of the measuring assembly 300 from the discharge port 340 under the action of gravity. At this time, the blocking part 410 of the baffle 400 closely fits at the outlet of the measuring cylinder 310 to prevent the powder from leaking. Then, according to the packaging requirements, the second push rod 520 of the moving structure 500 pushes the handle part 420 of the baffle 400 to make the baffle 400 open. The powder in the measuring cylinder 310 is put into the packaging bag or other packaging container under the action of gravity through the opened baffle 400. After the powder is put, the first push rod 510 of the moving structure 500 pushes the blocking part 410 of the baffle 400 to make the baffle 400 close, and the blocking part 410 re-fits at the outlet of the measuring cylinder 310, preparing for the next powder measurement and putting. Through the cycle of the above process, the powder packaging machine can realize continuous and accurate packaging of the powder.
[0042] In some embodiments, the buffer bin 200 comprises a buffer cover 330 and a rotatable distribution disc 320, the buffer cover 330 is connected with the feeding hopper 100, the distribution disc 320 is provided with a plurality of discharge ports 340 connected with the measuring cylinder 310, the buffer cover 330 is located in the distribution disc 320, the periphery of the buffer cover 330 abuts against the inner bottom wall of the distribution disc 320, part of the discharge ports 340 are located in the buffer cover 330, and the other part of the discharge ports 340 are located outside the buffer cover 330.
[0043] The buffer cover 330 is located above the entire buffer bin 200 and is connected with the feeding hopper 100, and the powder directly flows into the buffer cover 330 from the feeding hopper 100. The buffer cover 330 is provided with an opening at the bottom for matching with the distribution disc 320. The distribution disc 320 is located below the buffer cover 330 and is coaxially arranged, and the distribution disc 320 is disc-shaped and is provided with a plurality of discharge ports 340, the shapes and sizes of the discharge ports 340 match the upper end openings of the measuring cylinders 310, and the discharge ports 340 are used for distributing the powder in the buffer cover 330 to the measuring cylinders 310. The discharge ports 340 are uniformly distributed along the circumference of the distribution disc 320.
[0044] The working principle of the buffer bin 200 is as follows:
[0045] When the powder is poured from the hopper 100, it first enters the buffer cover 330 and accumulates in the buffer cover 330. At this time, the distribution disc 320 is in the initial position, and the discharge port 340 on the distribution disc 320 is partially located in the buffer cover 330 and partially located outside the buffer cover 330. The powder in the buffer cover 330 enters the measuring cylinder 310 located in the buffer cover 330. When the distribution disc 320 rotates, the measuring cylinder 310 containing the powder moves out of the buffer cover 330 to perform the dispensing, and the measuring cylinder 310 that has completed the dispensing re-enters the area of the buffer cover 330 to be re-charged.
[0046] Further, the measuring cylinder 310 and the discharge port 340 are connected in a clamping manner.
[0047] The upper end edge of the measuring cylinder 310 is provided with a protruding structure, which is arranged along the circumference of the measuring cylinder 310 and has a ring structure. The edge of the discharge port 340 is correspondingly provided with a clamping groove matched with the protruding structure. When the discharge port 340 is connected with the measuring cylinder 310, the protruding structure can be tightly embedded in the clamping groove to realize the clamping connection between the two. This clamping connection structure is simple, reliable, and convenient to install and disassemble.
[0048] Further, the top of the buffer cover 330 is provided with an observation port 350.
[0049] The observation port 350 is located at the top of the buffer cover 330, and can have a circular, square, or irregular shape. A transparent observation window can be installed at the observation port 350, and the operator can observe the storage condition of the powder in the buffer cover 330 in real time through the observation port 350, including the accumulation height, distribution uniformity, and whether there are agglomerates and other phenomena.
[0050] In some embodiments, the metering assembly 300 further comprises a rotating disc 360, and a plurality of measuring cylinders 310 are arranged on the rotating disc 360.
[0051] The rotating disc 360 in the metering assembly 300 is a circular disc structure, and a plurality of measuring cylinders 310 are uniformly distributed on the rotating disc 360. These measuring cylinders 310 are fixedly installed on the rotating disc 360 and synchronously rotate with the rotating disc 360. The lower end of the measuring cylinder 310 cooperates with the baffle 400, and the upper end communicates with the discharge port 340 of the distribution disc 320. The center of the rotating disc 360 is provided with a rotating shaft, and the rotating disc 360 is driven to rotate around the shaft by a motor or other driving device.
[0052] Further, the baffle 400 is rotationally connected with the rotating disc 360.
[0053] The baffle 400 is provided with a rotating shaft which is inserted into a corresponding hole on the rotating disc 360 and is rotatably connected to the rotating disc 360 through a bearing or other rotating connecting member. This connection mode enables the baffle 400 to freely rotate on the rotating disc 360 while maintaining a stable relative position with the rotating disc 360. The handle portion 420 of the baffle 400 is located on the outer side of the rotating disc 360, facilitating the operator to control the rotation of the baffle 400.
[0054] Further, the powder dispensing structure of the powder packaging machine further comprises a connecting assembly 600 for connecting the baffle 400 and the rotating disc 360, the connecting assembly 600 comprising a bolt 610, a spring 620 and a nut 630, the bolt 610 being capable of penetrating the baffle 400 and the rotating disc 360 and being fixed in cooperation with the nut 630, and the two ends of the spring 620 abutting against the baffle 400 and the nut 630, respectively.
[0055] During the operation of the powder packaging machine, due to the flow of the powder, vibration of the equipment and other factors, the connection between the baffle 400 and the rotating disc 360 may become loose or too tight. By rotating the nut 630, the compression degree of the spring 620 can be accurately adjusted, thereby changing the pressure between the baffle 400 and the rotating disc 360. When it is necessary to make the connection between the baffle 400 and the rotating disc 360 tighter, the nut 630 is tightened, the spring 620 is compressed, and the friction between the baffle 400 and the rotating disc 360 is increased; on the contrary, when it is necessary to make the baffle 400 rotate more flexibly, the nut 630 is loosened, the spring 620 is relaxed, and the pressure between the baffle 400 and the rotating disc 360 is reduced. This adjustable connection mode can ensure that the baffle 400 maintains stable rotation performance under different working conditions, improving the stability and accuracy of powder dispensing.
[0056] Further, the connecting assembly 600 further comprises a plug 640 which can penetrate the bolt 610, and the nut 630 is provided with a clearance groove 650 for avoiding the plug 640.
[0057] During the operation of the powder packaging machine, the equipment may be affected by various external forces such as vibration, impact, etc. These external forces may cause the connection between the nut 630 and the bolt 610 to loosen. By inserting the plug 640, the plug 640 penetrates the central hole of the bolt 610 and abuts against the clearance groove 650 in the nut 630, which can effectively limit the rotation of the nut 630 and enhance the connection stability between the nut 630 and the bolt 610. Even in the case of large vibration or impact of the equipment, the nut 630 is not easy to loosen, thereby ensuring that the connection between the baffle 400 and the rotating disc 360 always remains tight, improving the stability and reliability of powder dispensing.
[0058] In some embodiments, both the first push rod 510 and the second push rod 520 are provided with mounting slots 530 for adjusting their installation positions.
[0059] During the installation, adjustment or replacement of components of the powder packaging machine, it may be necessary to fine-tune the positions of the first push rod 510 and the second push rod 520 to ensure that they can accurately push the blocking part 410 and the handle part 420 of the baffle 400. Through the design of the mounting slots 530, the operator can easily move the positions of the push rods within the mounting slots 530 and then fix them in the appropriate positions with fixing bolts 610 or pins. This precise adjustment capability helps to improve the matching precision between the push rods and the baffle 400, reduces problems such as unsmooth or incomplete pushing caused by position deviation, and thus improves the accuracy and stability of powder dispensing.
