Description

Technical Field

[0001] The present invention relates to the technical field of toner density detection, and in particular to a method for measuring the density of backfill toner for grounding electrodes. Background Art

[0002] The backfill material of the grounding electrode is crucial for ensuring the effectiveness of the grounding system. When selecting the backfill material, it is necessary to consider the conductivity, stability, moisture absorption and retention ability of the material, as well as its influence on the soil resistivity. The backfill toner is mainly used to improve the soil conditions around the grounding electrode, reduce the soil resistivity, and thus reduce the grounding resistance. As a conductive material, the toner can improve the conductivity of the soil, making it easier for the current to flow into the ground and improving the efficiency and safety of the grounding system.

[0003] The density of the backfill toner is closely related to its conductive performance. Usually, it is necessary to detect the density of the backfill toner. Conventionally, the staff takes out the toner, then measures the volume of the toner with a measuring cup, weighs the toner, and then calculates the density of the toner using the density formula ρ = m / V, resulting in a low efficiency in measuring the density of the backfill toner. Summary of the Invention

[0004] In order to improve the problem of low efficiency in measuring the density of backfill toner, the present application provides a method for measuring the density of backfill toner for grounding electrodes.

[0005] In a first aspect, the method for measuring the density of backfill toner for grounding electrodes provided by the present application adopts the following technical solution: A method for measuring the density of backfill toner for grounding electrodes includes the following steps: S1: Take out a certain volume of backfill toner through a sampling device; S2: Weigh the taken-out toner; S3: Then use the density formula ρ = m / V, divide the mass by a certain volume to obtain the density of the backfill toner.

[0006] Preferably, the sampling device includes a bottom plate, an electronic scale is arranged on the bottom surface of the bottom plate, a tray is arranged on the electronic scale, a toner box is arranged on the bottom plate, a mounting frame is arranged on the top surface of the bottom plate, a rotating shaft is rotatably arranged on the inner top surface of the mounting frame, a moving plate is fixed to the bottom end of the rotating shaft, a moving rod passes through the top surface of the moving plate, a sampling cylinder is arranged at the bottom end of the moving rod, a motor I is arranged on the top surface of the mounting frame, an output shaft of the motor I is fixed to the top end of the rotating shaft, and a driving component for driving the moving rod to move vertically is arranged on the moving plate.

[0007] By adopting the above technical solution, the driving component drives the moving rod to drive the sampling cylinder to move downward, so that the sampling cylinder moves into the toner cartridge, and the sampling cylinder takes out a certain volume of toner from the toner cartridge. Then, the driving component drives the moving rod to move upward, so that the moving rod drives the sampling cylinder to move upward, and the sampling cylinder moves above the toner cartridge. Then, the first motor is started, the first motor drives the rotating shaft to rotate, the rotating shaft drives the moving plate to rotate, so that the moving plate drives the sampling cylinder to move above the electronic scale. The sampling cylinder places a certain volume of toner on the tray to weigh the mass of the toner, and then uses the density formula ρ = m / V to calculate the density of the backfilled toner, thereby improving the measurement efficiency of the density of the backfilled toner.

[0008] Preferably, the driving component includes a driving tube sleeved on the moving rod. The bottom end of the driving tube is rotatably installed on the top surface of the moving plate. The driving tube is threadedly connected to the moving rod. A first gear is arranged on the driving tube, and a second motor is arranged on the moving plate. A second gear is arranged on the output shaft of the second motor. The first gear meshes with the second gear. A limiting member for restricting the moving rod from rotating along with the driving tube is arranged on the moving plate.

[0009] By adopting the above technical solution, when the sampling cylinder is above the toner cartridge, the second motor is started. The output shaft of the second motor drives the second gear to rotate. The second gear drives the first gear to rotate. The first gear drives the driving tube to rotate, so that the driving tube drives the moving rod to drive the sampling cylinder to move downward into the toner cartridge.

[0010] Preferably, a limiting groove is formed on the outer peripheral surface of the moving rod. The limiting member includes a fixed block fixed to the bottom surface of the moving plate. A limiting block is fixed to the side surface of the fixed block close to the moving rod. The limiting block is inserted into the limiting groove. The limiting block is slidably connected to the moving rod vertically through the limiting groove.

[0011] By adopting the above technical solution, when the driving tube drives the moving rod to move vertically, the limiting block slides in the limiting groove, thereby reducing the possibility that the moving rod rotates along with the driving tube when the driving tube rotates.

[0012] Preferably, the sampling cylinder includes a cylinder fixed to the bottom end of the moving rod with an opening downward. A partition is fixed in the cylinder. The partition divides the cylinder into two sampling cavities with the same volume. A sealing cylinder is sleeved on the cylinder. The moving rod passes through the sealing cylinder. The moving rod is rotatably connected to the sealing cylinder. A sealing block for sealing one of the sampling cavities is fixed to the bottom surface of the sealing cylinder. A driving member for driving the sealing cylinder to rotate is arranged on the cylinder.

[0013] By adopting the above technical solution, when the sampling cylinder moves into the toner cartridge, the toner in the toner cartridge fills the sampling cavity. Then, the driving member drives the sealing cylinder to rotate, causing the sealing cylinder to drive the semi-circular block to rotate by a certain degree, so that the semi-circular block seals the sampling cavity filled with toner, thereby facilitating the sampling cylinder to take out the toner for weighing.

[0014] Preferably, the driving member includes a motor three disposed on the top surface of the cylinder. A gear three is provided on the output shaft of the motor three. A toothed ring is provided on the inner peripheral surface of the sealing cylinder. The gear three meshes with the toothed ring.

[0015] By adopting the above technical solution, when the sampling cylinder moves into the toner cartridge, the toner in the toner cartridge fills the sampling cavity. Start the motor three. The output shaft of the motor three drives the gear three to rotate, causing the gear three to drive the toothed ring to rotate, so that the toothed ring drives the sealing cylinder to rotate.

[0016] Preferably, a semi-cone is fixed to the bottom surface of the sealing block.

[0017] By adopting the above technical solution, a semi-cone is provided on the bottom surface of the sealing block. When the moving rod drives the sampling cylinder to move into the toner cartridge, the semi-cone pushes the toner in the toner cartridge away, thereby facilitating the insertion of the sampling cylinder into the toner.

[0018] Preferably, an annular groove is formed on the inner peripheral surface of the sealing cylinder. A plurality of installation grooves are formed on the inner peripheral surface of the annular groove. A ball is rotatably installed in the installation groove, and the ball can roll on the outer peripheral surface of the cylinder.

[0019] By adopting the above technical solution, when the sealing cylinder rotates, the balls on the sealing cylinder roll on the outer peripheral surface of the cylinder, thereby reducing the friction between the sealing cylinder and the cylinder, and thus facilitating the rotation of the sealing cylinder.

[0020] Preferably, a spring is fixed to the inner side surface of the installation groove away from the central axis of the cylinder. One end of the spring close to the central axis of the cylinder is fixed with a sliding block. Two installation blocks are fixed to the end surface of the sliding block close to the central axis of the cylinder. The ball is rotatably installed between the two installation blocks. A plurality of arc-shaped protrusions are fixed to the outer peripheral surface of the cylinder.

[0021] By adopting the above technical solution, when the sampling cylinder takes out the toner and moves above the electronic scale, the motor three is started. The output shaft of the motor three drives the gear three to rotate, and the gear three drives the gear ring to rotate, so that the gear ring drives the sealing cylinder to rotate, and the sealing cylinder drives the sealing block to rotate. When the toner in the sampling cavity falls into the tray, the sealing cylinder also drives the ball to rotate. When the ball moves onto the arc-shaped convex block, the ball drives the sliding block to move towards the installation groove, and the spring is in a compressed state. When the ball disengages from the arc-shaped convex block, the ball moves towards the direction close to the central axis of the cylinder under the elastic force of the spring, so that the ball impacts the outer peripheral surface of the cylinder, thereby causing the cylinder to vibrate and making the toner adhering to the inner wall of the cylinder fall off.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The driving assembly drives the moving rod to drive the sampling cylinder to move downward, so that the sampling cylinder moves into the toner cartridge, and the sampling cylinder takes out a certain volume of toner from the toner cartridge. Then the driving assembly drives the moving rod to move upward again, so that the moving rod drives the sampling cylinder to move upward, and the sampling cylinder moves above the toner cartridge. Then the motor one is started, so that the motor one drives the rotating shaft to rotate, and the rotating shaft drives the moving plate to rotate, so that the moving plate drives the sampling cylinder to move above the electronic scale. The sampling cylinder places a certain volume of toner on the tray to weigh the mass of the toner, and then uses the density formula ρ = m / V to calculate the density of the backfilled toner, thereby improving the measurement efficiency of the density of the backfilled toner. 2. When the sampling cylinder moves into the toner cartridge, the toner in the toner cartridge fills the sampling cavity. Then the driving member drives the sealing cylinder to rotate, so that the sealing cylinder drives the semi-circular block to rotate by a certain degree, thereby sealing the sampling cavity filled with toner by the semi-circular block, and thus facilitating the sampling cylinder to take out the toner for weighing. 3. When the sampling cylinder takes out the toner and moves above the electronic scale, the motor three is started. The output shaft of the motor three drives the gear three to rotate, and the gear three drives the gear ring to rotate, so that the gear ring drives the sealing cylinder to rotate, and the sealing cylinder drives the sealing block to rotate. When the toner in the sampling cavity falls into the tray, the sealing cylinder also drives the ball to rotate. When the ball moves onto the arc-shaped convex block, the ball drives the sliding block to move towards the installation groove, and the spring is in a compressed state. When the ball disengages from the arc-shaped convex block, the ball moves towards the direction close to the central axis of the cylinder under the elastic force of the spring, so that the ball impacts the outer peripheral surface of the cylinder, thereby causing the cylinder to vibrate and making the toner adhering to the inner wall of the cylinder fall off..

[0033] Referring to Figure 2 and Figure 4 , the sampling cylinder 3 includes a cylinder 31 fixed to the bottom end of the moving rod 2 with an opening downward. A partition 32 is fixed inside the cylinder 31. The partition 32 divides the cylinder 31 into two sampling chambers 33 with the same volume. A sealing cylinder 4 is sleeved on the cylinder 31.

A sealing block 41 for sealing one of the sampling chambers 33 is fixed to the bottom end of the inner peripheral surface of the sealing cylinder 4.

[0035] The implementation principle of the method for measuring the density of backfilled carbon powder of a grounding electrode in an embodiment of the present application is as follows: when it is necessary to measure the density of the backfilled carbon powder, start the first motor 17. The output shaft of the first motor 17 drives the rotating shaft 16 to rotate, so that the rotating shaft 16 drives the moving plate 18 to rotate. The moving plate 18 drives the sampling cylinder 3 to move, so that the sampling cylinder 3 moves to directly above the carbon powder box 13.

[0036] Then, start motor two 22, so that the output shaft of motor two 22 drives gear two 24 to rotate. Gear two 24 drives gear one 23 to rotate, causing gear one 23 to drive drive tube 21 to rotate. Drive tube 21 drives moving rod 2 to move downward, causing moving rod 2 to drive sampling cylinder 3 to move downward, so that sampling cylinder 3 moves into toner cartridge 13, and the toner in toner cartridge 13 fills one of the sampling cavities 33.

[0037] Next, start motor three 43, so that the output shaft of motor three 43 drives gear three 44 to rotate. Gear three 44 drives the rack to rotate, causing the rack to drive seal cylinder 4 to rotate. Seal cylinder 4 drives seal block 41 to rotate 180 degrees, so that seal block 41 seals the sampling cavity 33 filled with toner. Then, start motor two 22 again, so that the output shaft of motor two 22 drives gear two 24 to rotate in the reverse direction. Gear two 24 drives gear one 23 to rotate, causing gear one 23 to drive drive tube 21 to rotate. Drive tube 21 drives moving rod 2 to move upward, causing moving rod 2 to drive sampling cylinder 3 to move above toner cartridge 13. Next, start motor one 17, so that the output shaft of motor one 17 drives rotating shaft 16 to rotate in the reverse direction. Rotating shaft 16 drives moving plate 18 to rotate in the reverse direction, and moving plate 18 drives sampling cylinder 3 to move above tray 14.

[0038] Then, start motor three 43 again, so that the output shaft of motor three 43 drives gear three 44 to rotate. Gear three 44 drives the rack to rotate, causing the rack to drive seal cylinder 4 to rotate. Seal cylinder 4 drives seal block 41 to rotate 180 degrees, so that the sampling cavity 33 filled with toner is in an open state, so that the toner in sampling cavity 33 falls into tray 14. Then, use electronic scale 12 to weigh the toner in tray 14. Finally, use the density formula ρ = m / V, where mass is divided by a certain volume to obtain the density of the backfilled toner.

[0039] When seal cylinder 4 rotates to make the sampling cavity 33 filled with toner in an open state, seal cylinder 4 also drives ball 55 to rotate. When ball 55 moves to the arc-shaped convex block, the arc-shaped convex block drives ball 55 to move into mounting groove 51, and spring 52 is in a compressed state. When ball 55 disengages from the arc-shaped convex block, ball 55 moves in the direction close to cylinder 31 under the elastic force of spring 52, causing ball 55 to impact the outer peripheral surface of cylinder 31, so that cylinder 31 vibrates, which is convenient for the toner adhering to the inner wall of sampling cavity 33 to fall into tray 14, and further improves the measurement of toner density.
