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] Automated vacuum feeders for graphite usually refer to equipment used in the graphite production process to automatically add raw materials or additives to the graphite production system under vacuum. This equipment can improve production efficiency, ensure precise control during the production process, and reduce the risk of human error and contamination. With automated vacuum feeders, the graphite production process can be carried out more efficiently and stably.

[0003] The inside of the vacuum feeder is evacuated into a vacuum state, and then the powdered graphite powder is sucked into the vacuum feeder through the extraction tube. Generally, after the graphite powder reaches a certain capacity in the vacuum feeder, the outlet of the vacuum feeder 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 larger 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.

[0013] A filling method for an automatic vacuum feeder for graphite comprises the following steps: 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; S2: When the vacuum pump is used to evacuate the interior of the main body so that 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 to move 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; S3: driving the elastic lifting plate to rotate on the rotating frame, so that the elastic lifting plate tilts up, thereby pressing the arc-shaped pressing frame downward, so that the arc-shaped pressing frame is distributed inside the abutting groove, and at the same time, the engaging frame is stuck at the bottom of the connecting block; 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 by 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; 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 add the graphite powder inside the discharge barrel into the crucible.

[0014] 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: 1. The present invention drives the connection 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 frame slide on the inner wall of the discharge barrel through the strip slide hole, 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, the slope surface assembly block is driven to enter the inside of the discharge barrel, thereby sealing the bottom of the discharge barrel, and after all the graphite powder falling inside the trapezoidal funnel 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 against the inner wall of the trapezoidal funnel again, 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 can 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 that the graphite powder is prevented from raising large dust inside the crucible due to excessive falling force after filling, and the dust generated during filling is reduced, thereby improving the effect of the vacuum feeder in preventing dust from being raised.

[0015] 2. In the process of the electric push rod driving the connecting block to rise, the present invention will simultaneously drive the strong spring sheet and the knocking block to rise synchronously, and make the limit plug rod slide upward inside the limit sleeve. When the blocking block completely opens the through hole between the trapezoidal funnel and the discharging barrel, the limit plug rod will break away from the limit sleeve, and the elastic force of the strong spring sheet drives the knocking block to knock on the inner wall of the impact groove, thereby causing the inner wall of the trapezoidal funnel to vibrate, which can promote the downward flow rate of graphite powder and avoid the graphite powder still piling up and being unable to flow downward after the outlet is opened, thereby avoiding affecting the filler. When the knocking block is driven to reset, the knocking block is pressed downward to make the strong spring sheet bend to form elastic deformation, so that the limit plug rod is against the inner wall of the corresponding groove, so that when the circular ring bar descends, the limit plug rod enters the inside of the limit sleeve, and the elastic force applied by the strong spring sheet to the limit plug rod will cause the limit plug rod and the inner wall of the limit sleeve to generate a continuous force against each other, thereby improving the practicability of the device.

[0016] 3. Before drawing a vacuum, the present invention drives the blocking block and the conical block to seal the outlet between the trapezoidal funnel and the discharge barrel through the electric push rod. When the vacuum pump is used to evacuate the interior of the main body to make the interior of the main body close to a vacuum, the piston plate inside the piston cylinder will be driven to slide upward, stretching the reset 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, making the elastic lifting plate 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 engaging frame stuck at the bottom of the connecting block, thereby reinforcing the conical block, preventing the electric push rod from losing thrust after vacuuming for some reason, causing the blocking block and the conical block to move upward due to the suction force inside the main body to open the outlet, avoiding the graphite inside the main body from falling during the suction process, thereby avoiding affecting the normal operation of the feeder.

A suction joint 102 is fixedly connected to one end of the outer wall of the main body 1 close to the vacuum pump 101. Two rotating racks 103 are fixedly connected to the outer wall of the main body 1. Two supporting racks 106 are fixedly connected to the bottom of the circular ring plate 104. Two piston cylinders 105 are fixedly connected to the outer wall of the main body 1, and the piston cylinders 105 are connected to the inside of the main body 1. 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, a round rod 302 is fixedly connected to the bottom of the piston plate 301, a return spring 303 is fixedly connected to the bottom of the piston plate 301, the end of the return spring 303 away from the piston plate 301 is fixedly connected to the inner wall of the bottom 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 The pressing frame 306 has an outer wall of the arc-shaped lower pressing frame 306 which is away from the elastic lifting plate 305 and is fixedly connected with a chimeric frame 307. There are two groups of reinforcement mechanisms 3. The two groups of reinforcement mechanisms 3 are arranged in a circular array with the main body 1 as the center, driving the piston plate 301 inside the piston cylinder 105 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 rotate on the rotating frame 103, making the elastic lifting plate 305 tilt, thereby pressing the arc-shaped lower pressing frame 306 downward, making the arc-shaped lower pressing frame 306 distributed inside the abutting groove 409, and at the same time making the chimeric frame 307 stuck at the bottom of the connecting block 402; An oscillation mechanism 5 is arranged on the top of the two connecting blocks 402, and the oscillation mechanism 5 includes a circular ring strip 501, and two corresponding grooves 504 are arranged on the outer wall of the circular ring strip 501. Two strong spring pieces 502 are fixedly connected to the top of the annular sleeve 403, and a knocking block 503 is fixedly connected to the end of the strong spring piece 502 away from the annular sleeve 403, and the knocking block 503 corresponds to the impact groove 206. A limiting plug rod 505 is fixedly connected to the bottom of the knocking block 503, and a friction groove is arranged on the outer wall of the limiting plug rod 505, and the limiting plug rod 505 is embedded in the corresponding groove 504, and the limiting plug rod 505 is plugged into the inside of the limiting 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 limiting plug rod 505 The limiting sleeve 205 slides upward inside, and 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 detach 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. When the knocking block 503 is driven to reset, the knocking block 503 is pressed downward 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 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.

[0021] 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 frame 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 , and at the same time, drives the slope assembly block 407 to enter 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 discharge barrel 202, the slope assembly block 407 is used to prevent the graphite powder from falling directly below. When the bottom of the conical block 408 is against the inner wall of the trapezoidal funnel 201 again, 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.

[0022] Embodiment 2: as 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 be separated 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 downward to bend the strong spring sheet 502 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 501 descends, the limiting rod 505 enters the interior of the limiting sleeve 205, and the elastic force applied to the limiting rod 505 by the strong spring sheet 502 will cause the limiting rod 505 and the inner wall of the limiting sleeve 205 to generate a continuous force against each other.

[0023] 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 evacuates the inside of the main body 1 to make the inside of the main body 1 close to the vacuum, the piston plate 301 inside the piston cylinder 105 slides 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, one end of the extension rod 304 slides and rotates inside the elastic lifting plate 305, driving the elastic lifting plate 305 to rotate. The lifting plate 305 rotates on the rotating frame 103, so that the elastic lifting plate 305 is tilted, 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 to prevent the electric push rod 401 from losing thrust after vacuuming for some reason, so that the blocking block 406 and the conical block 408 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.

[0024] A filling method for an automatic vacuum feeder for graphite comprises the following steps: 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; S2: 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 a vacuum, the piston plate 301 inside the piston cylinder 105 will 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, one end of the extension rod 304 will slide and rotate inside the elastic lifting plate 305; S3: driving the elastic lifting plate 305 to rotate on the rotating frame 103, so that the elastic lifting plate 305 tilts up, 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 chimeric frame 307 is stuck at the bottom of the connecting block 402; 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 frame 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; S5: When the bottom of the conical block 408 abuts against the inner wall of the trapezoidal funnel 201 again, the slope assembly block 407 is driven to reset, and the outlet at the bottom of the discharge barrel 202 is opened, so that the graphite powder inside the discharge barrel 202 is added to the inside of the crucible.
