However, as the transmission distance gradually increases, the material gradually moves away from the vibration source. The material that is away is affected by the reduced vibration force and cannot be completely discharged, resulting in leftover material and waste. When the piled-up materials gradually increase to form bulges, the subsequent materials will continue to pile up together due to the limited vibration amplitude away from the vibration source, which will cause blockage.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. First embodiment

[0022] The present invention provides Figures 1 to 8 A bidirectional vibrating feeder shown in the figure comprises a feeding channel 1, a feeding hopper 12 is arranged in the middle of the upper surface of the feeding channel 1, and two symmetrical discharge pipes 13 are arranged on the bottom surface of the feeding channel 1. Under the action of the two discharge pipes 13, the material can be transmitted in two directions to achieve the purpose of multi-directional transmission. Cover plates 18 are arranged at both ends of the feeding channel 1. The cover plates 18 can seal the two ends of the feeding channel 1. At the same time, the cover plates 18 can be freely disassembled and new pipes can be spliced ​​to increase the size of the feeding channel 1. A support frame 14 is arranged below the feeding channel 1, and the support frame 14 can effectively play To achieve the supporting effect, the outer surface of the feeding channel 1 is provided with two symmetrical spring clamps 15, and the bottom surface of each spring clamp 15 is fixedly connected to the support frame 14. When the spring clamp 15 is installed on the pipe or other round object to be fixed, the user applies external force to expand the opening part of the clamp, so that its inner diameter is larger than the outer diameter of the fixed object. Once the clamp is put on the fixed object and the external force is released, the elastic force will restore the clamp to its original state and tightly wrap it around the surface of the fixed object. In this process, the spring clamp 15 firmly clamps the fixed object through the friction force generated by its elastic deformation.

[0023] Two symmetrical air supply components 2 and wind blocking components 3 are respectively arranged inside the feeding channel 1. The air supply component 2 can generate wind when started, and the wind force can be freely adjusted. The wind blocking component 3 can block part of the wind force. Only when the wind force reaches a certain level can the wind blocking component 3 be opened to allow the gas to circulate. The right end of the wind blocking component 3 is rotatably connected to a rotating component 4, and the rotating component 4 can rotate freely. Two symmetrical grooves 5 are arranged on the inner bottom wall of the feeding channel 1. A gravity sensor is arranged inside each groove 5. The gravity sensor can detect the material accumulated in the groove 5 in real time. The feeding method is adjusted accordingly according to the amount of accumulated material to avoid unclean discharge. The air supply component 2 includes a second mounting seat 201. The bottom surface of the second mounting seat 201 is provided with a mounting cylinder 202. The left side wall of the mounting cylinder 202 is provided with a motor 203. The output shaft of the motor 203 is provided with a group of second fan blades 204 arranged in a circle. When the motor 203 is started, the second fan blades 204 can be driven to rotate under the action of the output shaft of the motor 203, thereby generating wind force to blow the material inside the feeding channel 1 to move, thereby avoiding blockage caused by accumulation.

[0024] The wind blocking component 3 includes an air supply cylinder 301, an air collecting cylinder 302 is arranged inside the air supply cylinder 301, and both ends of the inner wall of the air collecting cylinder 302 are inclined. Under the action of the inclined surface, the wind force can be gathered to the center to increase its power. Two symmetrical first sliding grooves 303 are arranged inside the air collecting cylinder 302, and each first sliding groove 303 is slidably connected to the inside of a slider 304. A wind blocking plate 305 is arranged between the two sliders 304, and the diameter of the wind blocking plate 305 is consistent with the inner diameter of the air collecting cylinder 302. The wind blocking plate 305 can seal the air collecting cylinder 302 to prevent the wind from passing through. When the wind force gradually increases, the wind blocking plate 305 can gradually move to the right and move to the inclined surface of the air collecting cylinder 302, so that the wind blocking plate 305 and the air collecting cylinder 302 are connected. A gap appears between the cylinders 302, allowing part of the air to pass through the gap, thereby driving the first fan blade 406 on the right side to rotate, thereby achieving the purpose of rotating the rotating component 4. A positioning column 306 is provided at the axis center of the right side of the wind blocking plate 305, and a spring 8 is provided on the left side wall of each first slide groove 303. The other end of the spring 8 is fixedly connected to the slider 304 close to it, and each spring 8 is in a stretched state. When the wind blocking plate 305 gradually moves to the right with the wind force, the spring 8 is stretched to generate a reset elastic force, so that with the increase of the movement distance, the reset elastic force gradually increases, and a larger wind force is required to continue to make the wind blocking plate 305 move. When the force disappears, the wind blocking plate 305 can be reset under the action of elasticity to re-focus the wind cylinder 302 and close it.

[0025] The rotating component 4 includes a rotating shaft 401, a rotating disk 402 is provided at the right end of the rotating shaft 401, and a first fan blade 406 is provided at the left end of the rotating shaft 401. When the wind blocking component 3 is opened, the first fan blade 406 can be driven to rotate under the action of wind force, so that the rotating component 4 drives the scraping component 6 to rotate, so that the scraping component 6 directly hits the surface of the vibration bar 10, thereby generating vibration, and the material is moved by the vibration to avoid excessive accumulation of materials that cannot be transmitted. When the scraping component 6 is squeezed, it can shrink inward to avoid jamming during rotation. A cavity 403 is provided between the rotating disk 402 and the rotating shaft 401, and a first magnet 404 is slidably connected to the inside of the cavity 403, and the left side of the first magnet 404 is rotatably connected to the right end of the positioning column 306. The first magnet 404 is on the positioning column 306. Under the action of, the first magnet 404 can gradually move to the right and move to the rightmost end, thereby generating a magnetic repulsion force on the second magnet 7, so that each scraper assembly 6 extends outward to avoid contraction during scraping. A group of circularly arranged through grooves 405 are provided on the right side of the inner wall of the cavity 403, and a scraper assembly 6 is slidably connected to the inside of each through groove 405. The scraper assembly 6 can move along the trajectory of the through groove 405. The end of each scraper assembly 6 close to the axis of the rotating disk 402 is provided with a second magnet 7, and the first magnet 404 and the second magnet 7 have the same magnetic properties. The scraper assembly 6 includes a support rod 601, and each support rod 601 is inclined at one end away from the axis of the rotating disk 402. A scraper plate 602 is inclined when rotating, and the scraper plate 602 can push the material at the bottom to gradually move to the right, thereby achieving the purpose of discharging.

[0026] Under the action of the air supply component 2, wind force can be generated to exert a certain thrust on the material inside the feeding channel 1, so that the material away from the vibration source can move again to avoid accumulation and blockage. Through the cooperation of the rotating component 4 and the vibration bar 10, the scraper plate 602 can continuously collide with the vibration bar 10, thereby generating vibration, and the accumulated materials can be dispersed by vibration, and the materials can be discharged with the help of wind force. The electric push rod 11 moves the rotating component 4 to the lowest end, and under the action of the scraper plate 602, the remaining materials can be effectively and thoroughly discharged to avoid accumulation.

[0027] Two symmetrical first mounting seats 9 and a vibration bar 10 are respectively provided on the upper part of the inner wall of the feeding channel 1. The inner bottom wall of the vibration bar 10 is provided with a plurality of triangular spikes. When the scraper plate 602 hits the spikes, the scraper plate 602 can be retracted inwardly under the action of the inclined surface to avoid getting stuck. Two symmetrical electric push rods 11 are provided on the bottom surface of each first mounting seat 9, and the output ends of each group of electric push rods 11 are fixedly connected to the wind blocking components 3 close to them. Each vibration bar 10 is located above the scraper component 6. The electric push rods 11 can freely adjust the position of the rotating component 4 so that it can work in different areas.

[0028] A vibration component is installed in the middle of the feeding channel 1, and the vibration component includes a vibration bin 16. The vibration bin 16 is arranged in the middle of the bottom surface of the feeding channel 1. Two groups of symmetrical vibration motors 17 are arranged inside the vibration bin 16. When it is necessary to transport materials to the right end, the two vibration motors 17 on the right side are started to generate a certain vibration, so that the material gradually moves to the right. When it is necessary to transport materials to the left end, the two vibration motors 17 on the left side are started to generate a certain vibration, so that the material gradually moves to the left.

[0029] In actual use, the feeding channel needs to be extended according to the length of the required transmission. When extension is required, firstly, the two cover plates 18 are used to splice the appropriate pipes, and the discharge pipe 13 below is sealed. When the preparation work is completed, materials are continuously added to the feed hopper 12, and the vibration motor 17 is started to vibrate it, so that most of the materials are produced through vibration.

[0030] When the gravity sensor detects that the gravity reaches the first threshold, the motor 203 is started to rotate to generate a certain wind force, so that the air inside the feeding channel 1 can circulate, and the internal material is caused to vibrate and fly each time under the interaction of wind force and vibration. The movement distance increases, which can not only speed up the material transmission efficiency, but also avoid the situation where too much material accumulates and causes blockage. Part of the wind force will be gathered into the air collecting tube 302 to fill the air inside the air collecting tube 302 to prepare for the next adjustment.

[0031] When the gravity sensor detects that the gravity reaches the second threshold, the speed of the motor 203 is adjusted to the second gear, so that the gas inside the air collecting tube 302 gradually increases, and the air blocking plate 305 gradually moves to the right, so that the air blocking plate 305 moves to the inclined surface of the air collecting tube 302, so that a gap appears between the air blocking plate 305 and the air collecting tube 302, so that part of the air passes through the gap, thereby driving the first fan blade 406 on the right side to rotate, and under the action of the rotating shaft 401, the rotating disk 402 is driven to rotate continuously, and under the action of the centrifugal force, the support rod 601 pushes the scraper plate 602 to extend outward, so that the rotation coverage area is increased, so that the scraper plate 602 can directly hit the vibrating plate 406. The spikes of the moving bar 10 are moved to generate vibrations, and the cooperation of wind force and vibration can break up the piled-up materials and make them move again, so as to avoid the materials piling up and being unable to be transported. At the same time, due to the gap between the wind blocking plate 305 and the air collecting tube 302, exhaust is always being carried out, so that the position of the wind blocking plate 305 is always consistent. Part of the gas passing through the first fan blade 406 can transmit the wind force here to the scraper plate 602 under the action of the rotating disk 402, so as to clean the surface of the scraper plate 602, avoid the material from being adsorbed on the surface of the scraper plate 602, and at the same time make part of the gas closer to the material, so that it is more convenient to blow the material.

[0032] When the gravity sensor detects that the gravity reaches the third threshold, the electric push rod 11 is first started to move the rotating component 4 downward to keep it away from the vibration bar 10 to avoid collision, and then the motor 203 power is adjusted to the maximum to increase the generated wind force again, and the gas entering the wind tube 302 increases again. At this time, the gap between the wind blocker 305 and the wind tube 302 is not enough to exhaust air. Under the action of wind force, the wind blocker 305 moves to the right again, pushing the positioning column 306 to move the first magnet 404 to the rightmost end, so that a magnetic repulsion force is generated between the first magnet 404 and the multiple second magnets 7, so that each scraper component 6 extends outward to avoid contraction during scraping. When the scraper component 6 rotates to the lower side, it can better contact with the material below, and when the scraper plate 602 is tilted, the material can be gradually pushed to the right. Second embodiment

[0033] The present invention also provides a feeding method of a bidirectional vibrating feeder, and the specific operation method steps are as follows: S1. First, the material is put into the feeding channel 1 through the feeding hopper 12, and the vibration motor 17 is started to make the vibration bin 16 vibrate, and the vibration is transmitted to the feeding channel 1, and the material is pushed by the vibration.

[0034] S2. Secondly, the residual material is detected by the gravity sensor. When the gravity of the residual material reaches the first threshold, the motor 203 is started to drive the second fan blade 204 to rotate to generate wind force, and the material away from the vibration source is discharged by the wind force to avoid accumulation.

[0035] S3. When the gravity sensor detects that the remaining material reaches the second threshold, the rotation speed of the second fan blade 204 is gradually increased, so that the wind force component generated by it increases, and the wind blocking plate 305 is pushed to open the wind blocking component 3, so that the wind can drive the rotating component 4 on the right side to rotate through the wind blocking component 3, so that each scraping component 6 continuously hits the vibration bar 10 to vibrate itself, and the material is discharged again by generating new vibration and cooperating with the wind force.

[0036] S4. When the gravity sensor detects that the remaining material reaches the third threshold, the electric push rod 11 is started to move the rotating component 4 downward, and then the speed of the motor 203 is adjusted to the maximum to increase the generated wind force again, pushing the wind blocking plate 305 to move to the right again, so that the first magnet 404 moves to the rightmost end, and under the action of the magnetic force, each scraper component 6 extends outward. When the scraper component 6 rotates to the lower side, it can better contact with the material below, and when the scraper plate 602 is tilted, the material can be gradually pushed to the right.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

A feeding method of a bidirectional vibrating feeder as claimed in claim 7, characterized in that: The steps include: S1, firstly, the material is fed into the feeding channel (1) through the feeding hopper (12), and the vibration motor (17) is started to vibrate the vibration bin (16), and the vibration is transmitted to the feeding channel (1), and the material is pushed by the vibration; S2, secondly, detecting the residual material at this location by means of a gravity sensor, and when the gravity of the residual material reaches a first threshold value, starting the motor (203) to drive the second fan blade (204) to rotate and generate wind force, and using the wind force to discharge the material away from the vibration source, thereby avoiding accumulation; S3, when the gravity sensor detects that the amount of residual material reaches a second threshold, the second fan blade (204) is gradually rotated at an increased speed, thereby increasing the wind force component generated by the second fan blade (204), pushing the wind blocking plate (305) to open the wind blocking component (3), so that the wind force can drive the right rotating component (4) to rotate through the wind blocking component (3), so that each scraping component (6) continuously strikes the vibration bar (10) to generate vibrations, thereby discharging the material again by generating new vibrations in conjunction with the wind force; S4. When the gravity sensor detects that the residual material reaches the third threshold value, the electric push rod (11) is started to move the rotating component (4) downward, and then the rotation speed of the motor (203) is adjusted to the maximum, so that the generated wind force is increased again, and the wind blocking plate (305) is pushed to the right again, so that the first magnet (404) moves to the rightmost end. Under the action of the magnetic force, each scraper component (6) extends outward. When the scraper component (6) rotates to the lower side, it can better contact with the material below, and when the scraper plate (602) is set to be inclined, the material can be gradually pushed to the right.
