Description

Technical Field

[0001] The invention relates to the technical field of vacuum feeders, in particular to an automatic vacuum feeder for graphite and a filling method thereof. Background Art

[0002] An automated vacuum feeder for graphite is typically used in the graphite production process to automatically feed raw materials or additives into the system under vacuum. This equipment improves production efficiency, ensures precise control of the production process, and reduces the risk of human error and contamination. With this automated vacuum feeder, the graphite production process can be more efficient and stable.

[0003] By evacuating the interior of the vacuum feeder into a vacuum state, and then sucking the powdered graphite powder into the vacuum feeder through the extraction tube, generally after the graphite powder reaches a certain capacity in the vacuum feeder, the vacuum feeder outlet is opened and the graphite powder is filled into the crucible. However, the discharge port of the vacuum feeder is generally long. After the outlet of the vacuum feeder is opened, the powdered graphite will fall with greater force due to its greater height, which will cause the graphite powder to raise a large amount of dust inside the crucible due to excessive falling force after filling. As a result, more dust will still be generated during filling, which will cause the vacuum feeder to be less effective in preventing dust from being raised, thereby reducing the practicality of the device.

[0015] A method for filling graphite with an automatic vacuum feeder comprises the following steps:

[0016] S1: The electric push rod drives the blocking block and the conical block to block the outlet between the trapezoidal funnel and the discharge barrel;

[0017] S2: When the vacuum pump is used to evacuate the interior of the main body until the interior of the main body is close to vacuum, the piston plate inside the piston cylinder will slide upward, stretching the return spring, thereby driving the extension rod upward through the round rod, and at the same time causing one end of the extension rod to slide and rotate inside the elastic lifting plate;

[0018] S3: driving the elastic lifting plate to rotate on the rotating frame, causing the elastic lifting plate to tilt, thereby pressing the arc-shaped lower pressing frame downward, so that the arc-shaped lower pressing frame is distributed inside the abutting groove, and at the same time, the chiseled frame is stuck at the bottom of the connecting block;

[0019] S4: The connecting block is driven to rise by the electric push rod, and the two fitting control slides are driven to slide upward on the outer wall of the discharge barrel through the annular sleeve, so that the inner closed slide frame passes through the strip slide hole and slides on the inner wall of the discharge barrel, thereby pushing the blocking block and the conical block upward to leave the connection between the trapezoidal funnel and the discharge barrel;

[0020] S5: When the bottom of the conical block contacts the inner wall of the trapezoidal funnel again, it will drive the slope assembly block to reset, open the outlet at the bottom of the discharge barrel, and allow the graphite powder inside the discharge barrel to enter the crucible.

[0021] Compared with the prior art, the present invention provides an automatic vacuum feeder for graphite and a filling method thereof, which has the following beneficial effects:

[0022] 1. The present invention drives the connecting block to rise by an electric push rod, drives the two fitting control slides to slide upward on the outer wall of the discharge barrel through the annular sleeve, and makes the inner closed slide pass through the strip slide hole and slide on the inner wall of the discharge barrel, thereby pushing the blocking block and the conical block upward to leave the connection between the trapezoidal funnel and the discharge barrel, so that the graphite powder inside the trapezoidal funnel and the main body falls down, and when the two fitting control slides move upward, they simultaneously drive the slope assembly block to enter the inside of the discharge barrel, thereby sealing the bottom of the discharge barrel, and after the graphite powder falling inside the trapezoidal funnel all falls into the inside of the discharge barrel The sloped assembly block is used to prevent the graphite powder from falling directly below. When the bottom of the conical block is re-aligned with the inner wall of the trapezoidal funnel, the sloped assembly block will be driven to reset, and the outlet at the bottom of the discharge barrel will be opened, so that the graphite powder inside the discharge barrel will be added to the inside of the crucible, thereby achieving filling. At the same time, by reducing the height of the graphite powder falling, the force of the graphite powder falling is reduced, so as to avoid the graphite powder raising large dust inside the crucible due to excessive falling force after filling, and reduce the dust generated during filling, thereby improving the effect of the vacuum feeder in preventing dust from being raised.

[0023] When the push rod is driven to reset, the knocking block is pressed down to make the strong spring sheet bend and form elastic deformation, so that the limit rod is resisted with the inner wall of the corresponding groove, so that when the ring bar descends, the limit rod enters the interior of the limit sleeve, and the elastic force applied to the limit rod by the strong spring sheet will cause the limit rod and the inner wall of the limit sleeve to generate a continuous resisting force, thereby improving the practicability of the device.

[0024] When the vacuum is applied, the piston plate inside the piston cylinder is driven to slide upward, stretching the return spring, thereby driving the extension rod to move upward through the round rod, and at the same time making one end of the extension rod slide and rotate inside the elastic lifting plate, driving the elastic lifting plate to rotate on the rotating frame, causing the elastic lifting plate to tilt, thereby pressing the arc-shaped lower pressure frame downward, making the arc-shaped lower pressure frame distributed inside the abutment groove, and at the same time making the mosaic frame stuck at the bottom of the connecting block, thereby reinforcing the conical block, and preventing the electric push rod from losing thrust due to some reason after vacuum is applied, so that the blocking block and the conical block move upward due to the suction force inside the main body to open the outlet, and preventing the graphite inside the main body from falling during the suction process, thereby avoiding affecting the normal operation of the feeder.

[0040] The outer wall of the rotating frame 103 is provided with a reinforcement mechanism 3, which includes a piston plate 301, the piston plate 301 is slidably connected to the inside of the piston cylinder 105, the bottom of the piston plate 301 is fixedly connected to a round rod 302, the bottom of the piston plate 301 is fixedly connected to a return spring 303, the end of the return spring 303 away from the piston plate 301 is fixedly connected to the bottom inner wall of the piston cylinder 105, the end of the round rod 302 away from the piston plate 301 is fixedly connected to an extension rod 304, the end of the extension rod 304 away from the round rod 302 is slidably connected to an elastic lifting plate 305, the end of the elastic lifting plate 305 away from the extension rod 304 is rotatably connected to the outer wall of the rotating frame 103, and the end of the elastic lifting plate 305 away from the extension rod 304 is fixedly connected to an arc lower When the cam 305 is in the unlock state, the locking cam 307 is in the unlock state, and the locking cam 307 is locked.

[0041] An oscillation mechanism 5 is provided on the top of the two connecting blocks 402. The oscillation mechanism 5 includes a circular ring bar 501. Two corresponding grooves 504 are provided on the outer wall of the circular ring bar 501. Two strong spring pieces 502 are fixedly connected to the top of the annular sleeve 403. The end of the strong spring piece 502 away from the annular sleeve 403 is fixedly connected to a knocking block 503. The knocking block 503 corresponds to the impact groove 206. The bottom of the knocking block 503 is fixedly connected to a limited plug rod 505. The outer wall of the limit plug rod 505 is provided with a friction groove, and the limit plug rod 505 is engaged with the corresponding groove 504. The limit plug rod 505 is plugged into the inside of the limit sleeve 205. When the electric push rod 401 drives the connecting block 402 to rise, it will also drive the strong spring piece 502 and the knocking block 503 to rise synchronously, and make the limit plug rod 505 When the knocking block 503 is driven to reset, the knocking block 503 is pressed down to make the strong spring piece 502 bend to form elastic deformation, so that the limiting rod 505 is against the inner wall of the corresponding groove 504, so that when the circular ring bar 501 descends, the limiting rod 505 enters the limiting sleeve 205. The elastic force exerted on the limiting rod 505 by the strong spring piece 502 will cause the limiting rod 505 and the inner wall of the limiting sleeve 205 to generate a continuous counteracting force.

[0042] Working principle: The electric push rod 401 drives the connecting block 402 to rise, and the annular sleeve 403 drives the two fitting control slides 404 to slide upward on the outer wall of the discharge barrel 202, so that the inner closed slide 405 passes through the strip slide hole 203 and slides on the inner wall of the discharge barrel 202, thereby pushing the blocking block 406 and the conical block 408 upward to leave the connection between the trapezoidal funnel 201 and the discharge barrel 202, so that the graphite powder inside the trapezoidal funnel 201 and the main body 1 falls, and when the two fitting control slides 404 move upward, At the same time, it drives the slope assembly block 407 into the inside of the discharge barrel 202, thereby closing the bottom of the discharge barrel 202. After all the graphite powder falling inside the trapezoidal funnel 201 falls into the inside of the discharge barrel 202, the slope assembly block 407 prevents the graphite powder from falling directly below. When the bottom of the conical block 408 is again against the inner wall of the trapezoidal funnel 201, it will drive the slope assembly block 407 to reset and open the outlet at the bottom of the discharge barrel 202, so that the graphite powder inside the discharge barrel 202 is added to the inside of the crucible.

[0043] Example 2: Figure 1-Figure 7As shown, the working principle is as follows: when the electric push rod 401 drives the connecting block 402 to rise, it will also drive the strong spring piece 502 and the knocking block 503 to rise synchronously, and make the limiting rod 505 slide upward inside the limiting sleeve 205. When the blocking block 406 completely opens the through hole between the trapezoidal funnel 201 and the discharge barrel 202, the limiting rod 505 will break away from the limiting sleeve 205, and the elastic force of the strong spring piece 502 drives the knocking block 503 to knock on the inner wall of the impact groove 206, thereby causing the inner wall of the trapezoidal funnel 201 to vibrate. The downward flow rate of graphite powder is promoted to prevent the graphite powder from piling up and being unable to flow downward after the outlet is opened. When the knocking block 503 is driven to reset, the knocking block 503 is pressed down to bend the strong spring piece 502 to form an elastic deformation, so that the limiting rod 505 is against the inner wall of the corresponding groove 504, so that when the circular ring bar 501 descends, the limiting rod 505 enters the interior of the limiting sleeve 205. The elastic force applied to the limiting rod 505 by the strong spring piece 502 will cause the limiting rod 505 and the inner wall of the limiting sleeve 205 to generate a continuous force against each other.

[0044] Before the vacuum is drawn, the electric push rod 401 drives the blocking block 406 and the conical block 408 to block the outlet between the trapezoidal funnel 201 and the discharge barrel 202. When the vacuum pump 101 is used to evacuate the interior of the main body 1 so that the interior of the main body 1 is close to vacuum, the piston plate 301 inside the piston cylinder 105 is driven to slide upward, stretching the return spring 303, thereby driving the extension rod 304 to move upward through the round rod 302, and at the same time making one end of the extension rod 304 slide and rotate inside the elastic lifting plate 305, driving the elastic lifting plate 305 to move upward. The lifting plate 305 rotates on the rotating frame 103, causing the elastic lifting plate 305 to tilt up, thereby pressing the arc-shaped lower pressure frame 306 downward, so that the arc-shaped lower pressure frame 306 is distributed inside the abutment groove 409, and at the same time, the mosaic frame 307 is stuck at the bottom of the connecting block 402, thereby reinforcing the conical block 408, preventing the electric push rod 401 from losing thrust after vacuuming for some reason, causing the blocking block 406 and the conical block 408 to move upward due to the suction force inside the main body 1 to open the outlet, thereby preventing the graphite inside the main body 1 from falling during the suction process.

[0045] A method for filling graphite with an automatic vacuum feeder comprises the following steps:

[0046] S1: The electric push rod 401 drives the blocking block 406 and the conical block 408 to block the outlet between the trapezoidal funnel 201 and the discharge barrel 202;

[0047] S2: When the vacuum pump 101 is used to evacuate the interior of the main body 1 until the interior of the main body 1 is close to a vacuum, the piston plate 301 inside the piston cylinder 105 is driven to slide upward, stretching the return spring 303, thereby driving the extension rod 304 upward through the round rod 302, and at the same time causing one end of the extension rod 304 to slide and rotate inside the elastic lifting plate 305;

[0048] S3: driving the elastic lifting plate 305 to rotate on the rotating frame 103, causing the elastic lifting plate 305 to tilt, thereby pressing the arc-shaped lower pressing frame 306 downward, so that the arc-shaped lower pressing frame 306 is distributed inside the abutting groove 409, and at the same time, the chiseled frame 307 is stuck at the bottom of the connecting block 402;

[0049] S4: The connecting block 402 is driven to rise by the electric push rod 401, and the two fitting control slides 404 are driven to slide upward on the outer wall of the discharge barrel 202 by the annular sleeve 403, so that the inner closed slide 405 passes through the strip slide hole 203 and slides on the inner wall of the discharge barrel 202, thereby pushing the blocking block 406 and the conical block 408 upward to leave the connection between the trapezoidal funnel 201 and the discharge barrel 202;

[0050] S5: When the bottom of the conical block 408 contacts the inner wall of the trapezoidal funnel 201 again, the slope assembly block 407 is driven to reset, opening the outlet at the bottom of the discharge barrel 202, so that the graphite powder inside the discharge barrel 202 is added to the inside of the crucible.
