Description

Technical Field

[0001] This utility model relates to the field of powder density detection technology, specifically to an auxiliary loading device for powder density detection. Background Technology

[0002] In the field of powder density testing, the Leigh flask is a commonly used and important tool. Accurately adding powder into the Leigh flask plays a crucial role in obtaining accurate powder density test results. The traditional method involves the operator holding a container of powder and directly pouring it into the Leigh flask. During this operation, it is necessary to control the pouring speed and angle as much as possible to avoid spilling powder out of the flask. However, because the mouth and neck of the Leigh flask are very small, powder easily adheres to the neck and can easily spill out of the flask during pouring.

[0003] For example, Chinese utility model patent with publication number CN220063740U provides a feeding device for a Leigh flask. This device can facilitate the holding of powdery substances by setting a feeding funnel. By setting an adjustment component, a second telescopic tube can be inserted into the body of the Leigh flask, so that the powder will not stick to the neck of the Leigh flask. Furthermore, by using the telescopic function of the second telescopic tube, the powder can be added to a suitable position in the Leigh flask. By setting a fan-shaped airbag, the second telescopic tube can be blocked, thereby adjusting the amount of powder added to the Leigh flask.

[0004] However, because the neck of the Leigh flask is narrow, the hopper tube needs to be inserted into the Leigh flask for filling. The existing auxiliary tools used for filling the Leigh flask are not convenient for vibrating the inner tube during use, which causes the powder to accumulate in the tube and cause blockage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes an auxiliary feeding device for powder density detection, which solves the technical problem mentioned in the background art: because the neck of the Leigh flask is relatively narrow, it is necessary to insert the thin tube of the hopper into the Leigh flask for feeding. Existing auxiliary tools for feeding into the Leigh flask are inconvenient to vibrate the thin tube inside, which leads to the powder accumulating in the tube and causing blockage or reducing the feeding speed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary feeding device for powder density detection, comprising:

[0007] A tank body, on which a loading pipe is connected;

[0008] An installation ring is provided on one side of the tank body, and a flexible sleeve is provided on the installation ring, with a connecting ring provided at the end of the flexible sleeve;

[0009] A vibrating rod is slidably inserted inside the connecting ring, with one end extending out of the tank body and the other end extending into the loading pipe; and

[0010] A drive mechanism is provided on the tank body and connected to the vibrating rod to drive the vibrating rod to reciprocate on the flexible sleeve.

[0011] In a preferred embodiment, the drive mechanism includes:

[0012] A drive motor is mounted on the tank body, and its output shaft is equipped with a drive disc;

[0013] A connecting frame, slidably mounted on the tank body, has a drive ring at one end. The drive ring is sleeved on the vibrating rod, and its inner diameter is larger than the diameter of the vibrating rod.

[0014] The connecting rod has one end eccentrically hinged to the drive disk and the other end hinged to the connecting frame.

[0015] In a preferred embodiment, the top of the tank is provided with an openable and closable lid, and a handle is also provided on one side of the tank.

[0016] In a preferred embodiment, a control frame is slidably disposed inside the handle, and the connecting bracket is fixedly connected to the control frame.

[0017] In a preferred embodiment, the drive ring is provided with an extension rod, and two sets of baffles are arranged at intervals at the bottom of the extension rod. The end of the connecting frame is slidably disposed between the two sets of baffles, and elastic elements are provided on both sides of the end of the connecting frame and between the two sets of baffles.

[0018] In a preferred embodiment, a telescopic tube is slidably disposed inside the loading tube.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When using this auxiliary filling device, the powder is placed into the tank, and then the filling tube is inserted into the Leigh flask for filling. This ensures that the powder reaches the bottom of the flask directly and does not adhere to the body or neck of the flask. During the filling process, the vibrating rod can be controlled by the drive mechanism to swing back and forth on the flexible sleeve to vibrate the inside of the filling tube, preventing powder from accumulating inside the filling tube and causing blockage. This also increases the powder flow rate and effectively improves the filling efficiency. Furthermore, the vibrating rod can slide within the connecting ring to adjust the vibration position, allowing for vibration at different locations within the filling tube, thus enhancing the practical value of this auxiliary filling device.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0028] Example:

[0029] like Figure 1 As shown, this utility model provides an auxiliary feeding device for powder density testing, including a tank 1, a feeding pipe 16 connected to the tank 1, an openable and closable cover 2 on the top of the tank 1, and a handle 3 on one side of the tank 1. A telescopic tube 17 is slidably arranged inside the feeding pipe 16.

[0030] When in use, open the cap 2 and pour the powder into the tank 1. Then tilt the device so that the filling tube 16 extends downward into the Leigh bottle. When the neck of the selected Leigh bottle is long, the telescopic tube 17 can also be pulled out to ensure that the powder can be directly delivered to the bottom of the Leigh bottle and will not stick to the neck, thereby improving the accuracy of the detection structure.

[0031] like Figures 1 to 3As shown, in this embodiment, a mounting ring 6 is provided on one side of the tank body 1, a flexible sleeve 7 is provided on the mounting ring 6, and a connecting ring 8 is provided at the end of the flexible sleeve 7. A vibrating rod 18 is slidably inserted inside the connecting ring 8. One end of the vibrating rod 18 extends outside the tank body 1, and the other end extends into the loading pipe 16. A drive mechanism connected to the vibrating rod 18 is provided on the tank body 1. The drive mechanism drives the vibrating rod 18 to reciprocate on the flexible sleeve 7. The drive mechanism includes a drive motor 13 provided on the tank body 1. A drive disk 14 is provided on the output shaft of the drive motor 13. A connecting frame 5 is slidably provided on the tank body 1. A drive ring 10 is provided at one end of the connecting frame 5. The drive ring 10 is sleeved on the vibrating rod 18, and its inner diameter is larger than the diameter of the vibrating rod 18. One end of the connecting rod 15 is eccentrically hinged to the drive disk 14, and the other end is hinged to the connecting frame 5.

[0032] During the loading process, the drive motor 13 controls the drive disc 14 to rotate. As the drive disc 14 rotates, it drives the connecting frame 5 to slide back and forth on the tank 1 via the connecting rod 15, thereby driving the drive ring 10 to move. The vibrating rod 18 is installed via the flexible sleeve 7, allowing it to swing on the tank 1. During its movement, the drive ring 10 controls one end of the vibrating rod 18 to move within the loading pipe 16, striking the inner wall of the pipe and achieving a vibration effect to increase the flow rate of the powder. A control frame 4 is slidably installed inside the handle 3, and the connecting frame 5 is fixedly connected to the control frame 4. When only small-amplitude vibration is needed, the control frame 4 can be manually driven to slide, driving the vibrating rod 18 to move, allowing for convenient selection of electric or manual vibration according to actual conditions.

[0033] like Figure 1 , 2 As shown, in this embodiment, an extension rod 9 is provided on the drive ring 10, and two sets of baffles 11 are arranged at intervals at the bottom of the extension rod 9. The end of the connecting frame 5 is slidably disposed between the two sets of baffles 11, and elastic elements 12 are provided on both sides of the end of the connecting frame 5 between the two sets of baffles 11. During the sliding process of the vibrating rod 18, the swing range of its end will change. By movably setting the connecting frame 5 and the extension rod 9, and arranging the elastic elements 12 to transmit power, the vibration rod 18 is prevented from breaking due to excessive swing amplitude.

[0034] The specific usage and beneficial effects of this utility model are as follows:

[0035] When using this auxiliary filling device, the powder is placed into the tank 1, and then the filling tube 16 is inserted into the Leigh bottle for filling. This ensures that the powder reaches the bottom of the bottle directly and does not adhere to the bottle body or neck. During the filling process, the vibrating rod 18 can be controlled by the drive mechanism to swing back and forth on the flexible sleeve 7 to vibrate the inside of the filling tube 16, preventing powder from accumulating inside the filling tube 16 and causing blockage. This increases the powder flow rate and effectively improves the filling efficiency. Furthermore, the vibrating rod 18 can slide within the connecting ring 8 to adjust the vibration position, allowing vibration to be performed at different locations within the filling tube 16, thus enhancing the practical value of this auxiliary filling device.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
