Description

Technical Field

[0001] This utility model relates to the field of powder density measurement technology, specifically to an automatic leveling powder loose density measuring instrument. Background Technology

[0002] In the field of powder material production and processing, the loose packing density of powder is a crucial indicator. It not only directly reflects the compactness of the packing between powder particles but also has a profound impact on the flowability and filling properties of powder materials. For example, in the graphite manufacturing industry, a higher loose packing density allows electrodes to fill more active material within a limited space, increasing the volumetric energy density of the battery and thus extending its range. Simultaneously, a uniform and appropriate loose packing density distribution helps ensure the stability of the internal electric field and ion transport of the electrode, playing a decisive role in the battery's charge-discharge efficiency and cycle life. In graphite electrode production, loose packing density affects the forming quality of the green body and subsequent processing performance. Precise control of loose packing density can effectively reduce product defects, improve yield and product quality, and lower production costs.

[0003] Traditional methods for measuring the loose density of powders mainly rely on manual operation. In a typical measurement process, the operator must first slowly pour the powder into a funnel, then let it flow into a measuring cylinder, and finally manually smooth the powder surface with a scraper. Manual smoothing is highly susceptible to the influence of the operator's subjective factors, such as different scraper force / angle, which can cause inconsistent surface smoothness of the powder, ultimately leading to measurement errors.

[0004] Therefore, this utility model proposes an automatic leveling powder loose density measuring instrument to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic leveling powder loose density measuring instrument to solve the problem that manual leveling operations in the prior art cause inconsistent surface flatness of the powder, ultimately leading to measurement errors.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An automatic leveling powder loose density measuring instrument includes a funnel body, which is connected to a first lifting mechanism via a fixing ring. The first lifting mechanism is connected to a base. A blocking rod is longitudinally slidably connected to the bottom of the funnel body, and a bracket is connected to the top of the funnel body. The blocking rod is longitudinally slidably connected to the bracket via a connecting rod. The connecting rod is connected to a second lifting mechanism via a connecting plate. The second lifting mechanism is connected to the fixing ring. A measuring cylinder is disposed below the funnel body and is connected to the base. A positioning mechanism is disposed inside the base corresponding to the measuring cylinder. A leveling blade is disposed on the top of the measuring cylinder and is connected to a driving device. The driving device is connected to the base via a connecting frame. A guide rod is fixedly connected to the connecting frame. The guide rod is arranged parallel to the driving device, and the leveling blade is sleeved on the guide rod.

[0008] By adopting the above technical solution, the surface flatness of the graphite powder is ensured to be consistent after each leveling process, reducing measurement errors caused by human factors.

[0009] Furthermore, the top of the blocking rod is inclined; the bottom surface of the measuring cylinder is inclined; and the top surface of the base is inclined.

[0010] By adopting the above technical solutions, the accumulation and residue of powder can be reduced.

[0011] Furthermore, a vibration motor is installed inside the base corresponding to the measuring cylinder, and the vibration motor is located at the bottom of the measuring cylinder.

[0012] By adopting the above technical solution, the powder inside the measuring cylinder can be vibrated, making the powder more uniform and improving the accuracy of the measurement.

[0013] Furthermore, a recycling channel is provided at the bottom of the base, the bottom surface of the recycling channel is inclined, and multiple leakage holes are evenly provided on the periphery of the base corresponding to the measuring cylinder. The leakage holes are connected to the recycling channel, and an opening is provided at the end of the recycling channel.

[0014] By adopting the above technical solution, excess powder falling off during the leveling process falls into the recycling channel through the leakage hole and is discharged from the opening, making cleaning convenient.

[0015] Furthermore, a scraping blade is detachably connected to the scraping plate; the connecting frame is telescopically oriented and detachably connected to the base.

[0016] By adopting the above technical solution, the connecting frame can be adjusted to a suitable height according to the height of the measuring cylinder and fixed on the base, so that the scraper is located above the measuring cylinder; at the same time, the guide rod can ensure the stability of the scraper during the movement process.

[0017] Furthermore, the positioning mechanism includes a first bevel gear rotatably connected to the base via a rotating rod and a second bevel gear meshing with the first bevel gear. A positioning post is connected to the second bevel gear, and a positioning block is connected to the end of the positioning post. An L-shaped positioning groove is opened at the bottom of the measuring cylinder corresponding to the positioning block. A rotating handle is connected to the end of the rotating rod, and a scale line is opened on the rotating handle.

[0018] By adopting the above technical solution, the position of the positioning block can be accurately controlled according to the scale lines on the rotating handle, ensuring the stability of positioning.

[0019] Further, the first lifting mechanism includes a first lead screw, a first motor, a first lifting frame, and a first lifting part. The first lifting part is longitudinally slidably connected within the first lifting frame. The first lead screw is rotatably connected to the first lifting frame and threadedly connected to the first lifting part. The first motor is fixedly connected to the first lifting frame and coaxially connected to the first lead screw. The fixing ring is fixedly connected to the first lifting part. The second lifting mechanism includes a second lead screw, a second motor, a second lifting frame, and a second lifting part. The second lifting part is longitudinally slidably connected within the second lifting frame. The second lead screw is rotatably connected to the second lifting frame and threadedly connected to the second lifting part. The second motor is fixedly connected to the second lifting frame and coaxially connected to the second lead screw. The connecting plate is fixedly connected to the second lifting part.

[0020] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. The scraper blade of this utility model is connected to the drive device and performs the scraping operation under the guidance of the guide rod, ensuring that the surface flatness of the graphite powder is consistent after each scraping, reducing measurement errors caused by human factors. The scraper blade is detachably connected to the scraper blade. When the scraper blade wears out after long-term use, it can be replaced in time to ensure consistent scraping effect and maintain high precision.

[0022] 2. This utility model can adjust the height of the funnel body through the first lifting mechanism and precisely control the lifting of the blocking rod through the second lifting mechanism. It can accurately adjust the starting position and speed of powder filling according to different measurement needs, avoiding the difference in powder accumulation in the measuring cylinder caused by inconsistent pouring speed, height and angle. This ensures that the powder filling state is highly consistent in each measurement, thus guaranteeing the accuracy of the measurement results from the source. Attached Figure Description

[0035] The working process of this utility model is as follows:

[0036] First, place the measuring cylinder 10 on the base 4. By rotating the handle 27, the rotating rod 22 rotates, causing the first bevel gear 21 to rotate.

[0037] Then, the first motor 30 drives the first lead screw 29 to rotate, causing the first lifting part 32 to raise the funnel body 1 to a suitable height. Next, the second motor 34 is activated, driving the second lead screw 33 to rotate, causing the second lifting part 36 to raise the connecting plate 8, connecting rod 7, and blocking rod 5, opening the bottom outlet of the funnel body 1. Powder is then poured into the funnel body 1, falling through the outlet at the bottom of the funnel body 1 into the measuring cylinder 10. Once a certain amount of powder has been added, the second motor 34 is activated in reverse, causing the blocking rod 5 to descend and close the bottom outlet of the funnel body 1.

[0038] As the powder falls, the vibration motor 16 inside the base 4 is activated. Located at the bottom of the measuring cylinder 10, the vibration motor 16 vibrates the powder inside, making it more uniform and improving measurement accuracy. Then, the drive device 13 is activated, driving the leveling blade 12 to move along the guide rod 15 at the top of the measuring cylinder 10, leveling excess powder and making the powder surface smooth. Excess powder falling during leveling falls through the drain hole 18 into the recovery channel 17 and is discharged from the opening for easy cleaning. The measuring cylinder 10 is then removed, and the mass m and volume V of the powder inside are measured. The loose density of the powder is calculated using the density formula.
