Therefore, it is very necessary to design a leak-proof quantitative feeding device with high quantitative performance. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a leak-proof quantitative feeding device, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical scheme: a leak-proof quantitative feeding device, comprising a frame, a quantitative device is arranged above the frame, a scraper device is arranged above the quantitative device, a feed pipe is arranged below the scraper device, and a leak-proof device is arranged below the feed pipe.

[0006] The frame comprises a base and an external tank body, and the external tank body is fixedly connected to the upper surface of the base.

[0007] The quantitative device includes an internal tank body, a first connecting rod, a hinged rod, a blanking plate, an annular tube, a square baffle, and a sliding rod. The internal tank body is fixedly connected to the inner wall of the external tank body, the sliding rod is arranged at the axis of the internal tank body, one end of the first connecting rod is fixedly connected to the outer surface of the sliding rod, the hinged rod is fixedly connected to the other end of the first connecting rod, the blanking plate is fixedly connected to one side of the hinged rod, the annular tube is arranged below the blanking plate, and the square baffle is fixedly connected to the inner wall of the internal tank body.

[0008] The bottom of the inner tank body is provided with a feeding capillary, the top of the feeding plate is in an arc shape and the feeding plate fits with the feeding capillary at the bottom of the inner tank body, the size of the annular tube is larger than the feeding plate, one side of the square baffle is fitted with the feeding plate, and a connecting rod is provided at a position of the square baffle away from the axis of the feeding plate, and the first connecting rod is provided with multiple grooves, when the external cylinder at the top of the sliding rod works, the sliding rod is pushed to move downward, and at the same time, the first connecting rod on the outer surface of the sliding rod moves downward, and when the hinged rod is subjected to a downward force, the hinged rod changes the inclination angle of the feeding plate, and the top of the feeding plate is affected The force is opened, and the material slides from the inner tank body to the bottom of the discharge plate. The square baffle prevents the sliding material from splashing. At this time, the bottom of the discharge plate is in a closed state, and the material slides to the bottom of the discharge plate. When the top cylinder resets the sliding rod to its original position, the first connecting rod moves upward at the same time, and the hinged rod resets the inclination angle of the discharge plate. At this time, the bottom of the discharge plate is opened, and the material that has slid to the bottom of the discharge plate begins to slide. At the same time, the closed material on the top of the discharge plate no longer slides, and the annular tube makes the sliding material slide in a fixed direction. The quantitative device saves human resources and reduces the errors and risks caused by manual operation.

[0009] According to the above technical solution, the scraper device includes a threaded rod, a base plate, a first protrusion, a second connecting rod, a ring, and a scraper plate. The threaded rod is fixedly connected to the lower surface of the sliding rod, the base plate is fixedly connected to the inner wall of the internal tank body, the first protrusion is fixedly connected to the upper surface of the base plate, one end of the second connecting rod is fixedly connected to the outer surface of the threaded rod, the ring is fixedly connected to the other end of the second connecting rod, the scraper plate is fixedly connected to the bottom of the ring, the ring is rotatably connected to the inner wall of the internal tank body discharge tube, and the first protrusion is engaged with the groove of the first connecting rod.

[0010] When the sliding rod moves downward, the threaded rod connected to the sliding rod also moves downward, and the second connecting rod is affected by the threaded rod and starts to rotate around the threaded rod, thereby driving the ring connected to the threaded rod to rotate. The scraper plate at the bottom of the ring rotates with the ring, and the scraper plate scrapes the material from the discharge tube at the bottom of the internal tank body to clean the attached material to avoid waste. When the sliding rod moves downward, the first connecting rod on the outer surface of the sliding rod moves downward. When the first connecting rod slides through and contacts the first protrusion on the upper surface of the bottom plate, the groove of the first connecting rod engages and slides with the first protrusion, and the first connecting rod vibrates, causing the internal tank body to vibrate, which can cause the material attached to the inner wall of the internal tank body to fall off, prevent material accumulation and adhesion, maintain the efficient operation of the equipment, and help clean the dust accumulated in the external tank body and the internal tank body.

[0011] According to the above technical scheme, the leakage prevention device includes a third connecting rod, a fourth connecting rod, a special-shaped plate, a barrel cover ring, a material receiving barrel, a fixed block, a second protrusion, a third protrusion, and an arc-shaped baffle. The third connecting rod is fixedly connected to the end of the hinged rod away from the first connecting rod, one end of the fourth connecting rod is fixedly connected to the outer surface of the third connecting rod, the special-shaped plate is rotatably connected to the bottom of the third connecting rod, the barrel cover ring is fixedly connected to the bottom of the special-shaped plate, the material receiving barrel is arranged below the barrel cover ring, the fixed block is arranged in multiple places, and all of them are fixedly connected to the outer surface of the material receiving barrel, the second protrusion is fixedly connected to the fixed block on both sides, the third protrusion is fixedly connected to the inner wall of the barrel cover ring, the arc-shaped baffle is fixedly connected to the other end of the fourth connecting rod, the barrel cover ring is provided with a groove, the arc-shaped baffle is in contact with the material receiving barrel, the special-shaped plate has a connecting rod at the rotating shaft, and the connecting rod is slidably connected to the discharge pipe.

[0012] Before the material falls, the receiving barrel is pushed to the bottom of the base, and the arc-shaped baffle plate prepares the receiving barrel to be placed under the barrel cover ring to ensure that the barrel cover ring is completely matched with the receiving barrel when it falls. When the inclination angle of the hinged rod is deflected, the third connecting rod is forced to move downward, and the special-shaped plate is affected by the hinge axis at the bottom of the third connecting rod. The special-shaped plate begins to deflect, and the connecting rod on one side of the special-shaped plate slides with the discharge pipe, and the barrel cover ring moves downward. The second protrusions on both sides of the fixed block slide with the third protrusion on the inner wall of the barrel cover ring. When the second protrusion slides to above the third protrusion, the barrel cover ring is completely matched with the receiving barrel, completing the sealing work, so that the material will not splash when it is discharged, and the To ensure that the material will not be blown away by the wind, when the tilt angle of the hinged rod is reset to its original position, the third connecting rod moves upward, and the barrel cover ring moves with it. At this time, the receiving barrel is slightly pulled up, and under the effect of gravity, the second protrusion slides downward, and the receiving barrel falls to a distance. The fourth connecting rod on the outer surface of the third connecting rod moves along, and the arc-shaped baffle connected to the fourth connecting rod slides on the outer surface of the receiving barrel. When the receiving barrel falls, it is ensured that the receiving barrel falls to its original position.

The annular tube 205 is larger than the feeding plate 204. One side of the square baffle 206 fits with the feeding plate 204. A connecting rod is provided on the square baffle 206 away from the axis of the feeding plate 204. The first connecting rod 202 has multiple grooves.

[0031] When the external cylinder on the top of the sliding rod 207 works, the sliding rod 207 is pushed to move downward, and at the same time, the first connecting rod 202 on the outer surface of the sliding rod 207 moves downward. When the hinged rod 203 is subjected to a downward force, the hinged rod 203 changes the inclination angle of the unloading plate 204, and the top of the unloading plate 204 is forced to open, and the material slides from the inside of the internal tank body 201 to the bottom of the unloading plate 204. The square baffle 206 prevents the sliding material from splashing.

When the top cylinder resets the sliding rod 207 to its original position When the material is in the state of being moved downward, the first connecting rod 202 moves upward at the same time, and the hinge rod 203 resets the inclination angle of the discharge plate 204. At this time, the bottom of the discharge plate 204 opens, and the material that has slid to the bottom of the discharge plate 204 begins to slide down. At the same time, the closed material on the top of the discharge plate 204 stops sliding down, and the annular tube 205 makes the sliding material slide in a fixed direction. The quantitative device 2 saves human resources and reduces the errors and risks caused by manual operation, thereby ensuring the consistency of product quality and the stability of the production process, saving raw materials, reducing resource consumption in the production process, and effectively avoiding material waste and reducing costs.

[0033] When the sliding rod 207 moves downward, the threaded rod 301 connected to the sliding rod 207 also moves downward, and the second connecting rod 304 is affected by the threaded rod 301 and starts to rotate around the threaded rod 301, while driving the collar 305 connected to the threaded rod 301 to rotate, and the scraper plate 306 at the bottom of the collar 305 rotates with the collar 305, and the scraper plate 306 scrapes the material from the feeding capillary at the bottom of the internal tank body 201 to clean up the attached material to avoid waste. As the first connecting rod 202 moves downward, when the first connecting rod 202 slides through and contacts the first protrusion 303 on the upper surface of the bottom plate 302, the groove of the first connecting rod 202 engages and slides with the first protrusion 303, and the first connecting rod 202 vibrates, causing the internal tank body 201 to vibrate, which can make the material attached to the inner wall of the internal tank body 201 fall off, prevent material accumulation and adhesion, maintain the efficient operation of the equipment, and help clean the dust accumulated in the external tank body 102 and the internal tank body 201.

[0034] The anti-leakage device 4 includes a third connecting rod 401, a fourth connecting rod 402, a special-shaped plate 405, a barrel cover ring 406, a material receiving barrel 407, a fixing block 408, a second protrusion 409, a third protrusion 410, and an arc-shaped baffle 411. The third connecting rod 401 is fixedly connected to the end of the hinge rod 203 away from the first connecting rod 202, one end of the fourth connecting rod 402 is fixedly connected to the outer surface of the third connecting rod 401, the special-shaped plate 405 is rotatably connected to the bottom of the third connecting rod 401, and the barrel cover ring 406 is fixedly connected to the bottom of the special-shaped plate 405. The receiving barrel 407 is arranged below the barrel cover ring 406, and the fixing blocks 408 are arranged in multiple places and are all fixedly connected to the outer surface of the receiving barrel 407. The second protrusions 409 are fixedly connected to the two sides of the fixing blocks 408. The third protrusions 410 are fixedly connected to the inner wall of the barrel cover ring 406. The arc-shaped baffle plate 411 is fixedly connected to the other end of the fourth connecting rod 402. The barrel cover ring 406 is provided with a groove. The arc-shaped baffle plate 411 is in contact with the receiving barrel 407. A connecting rod is provided at the rotating shaft of the special-shaped plate 405, and the connecting rod is slidably connected to the discharge pipe 5.

[0035] Before the material falls, the receiving barrel 407 is pushed to the bottom of the base 101, and the arc-shaped baffle plate 411 prepares the receiving barrel 407 to be placed under the barrel cover ring 406, ensuring that the barrel cover ring 406 is completely matched with the receiving barrel 407 when it falls. When the tilt angle of the hinged rod 203 is deflected, the third connecting rod 401 is forced to move downward, and the special-shaped plate 405 is affected by the hinge axis at the bottom of the third connecting rod 401. The special-shaped plate 405 begins to deflect, and the connecting rod on one side of the special-shaped plate 405 slides with the discharge pipe 5, and the barrel cover ring 406 moves downward. The second protrusions 409 on both sides of the fixed block 408 slide with the third protrusions 410 on the inner wall of the barrel cover ring 406. When the second protrusion 409 slides to above the third protrusion 410, the barrel cover ring 406 is completely matched with the receiving barrel 407, completing the sealing work, so that the material will not splash when it is discharged, and the material will not be blown away by the wind. When the tilt angle is reset to its original position, the third connecting rod 401 moves upward, and the barrel cover ring 406 moves with it. At this time, the material receiving barrel 407 is slightly pulled up. Under the effect of gravity, the second protrusion 409 slides downward, and the material receiving barrel 407 is dropped to a distant place. The fourth connecting rod 402 on the outer surface of the third connecting rod 401 moves accordingly, and the arc-shaped baffle 411 connected to the fourth connecting rod 402 slides on the outer surface of the material receiving barrel 407. When the material receiving barrel 407 is dropped, it is ensured that the material receiving barrel 407 is dropped to its original position. The leak-proof device 4 can effectively reduce the possibility of dust leakage to the surrounding environment, protect the surrounding air, reduce the material concentration in the workplace, improve the operator's working environment and air quality, help reduce occupational health problems, improve the safety of the staff, and at the same time reduce the waste caused by material leakage, effectively save costs and improve production efficiency.

[0036] Working principle: When the external cylinder on the top of the sliding rod 207 works, the sliding rod 207 is pushed to move downward, and at the same time, the first connecting rod 202 on the outer surface of the sliding rod 207 moves downward. When the hinged rod 203 is subjected to a downward force, the hinged rod 203 changes the inclination angle of the unloading plate 204, and the top of the unloading plate 204 is forced to open, and the material slides from the inside of the internal tank body 201 to the bottom of the unloading plate 204. The square baffle 206 prevents the sliding material from splashing. At this time, the bottom of the unloading plate 204 is in a closed state, and the material slides to the bottom of the unloading plate 204. When the top cylinder resets the sliding rod 207 When the material is at the original position, the first connecting rod 202 moves upward at the same time, and the hinge rod 203 resets the inclination angle of the material discharge plate 204. At this time, the bottom of the material discharge plate 204 opens, and the material that slides to the bottom of the material discharge plate 204 begins to slide. At the same time, the closed material on the top of the material discharge plate 204 stops sliding, and the annular tube 205 makes the sliding material slide in a fixed direction. The quantitative device 2 saves human resources and reduces the errors and risks caused by manual operation, ensuring the consistency of product quality and the stability of the production process, saving raw materials, reducing resource consumption in the production process, and effectively avoiding material waste and reducing costs.

[0037] When the sliding rod 207 moves downward, the threaded rod 301 connected to the sliding rod 207 also moves downward, and the second connecting rod 304 is affected by the threaded rod 301 and starts to rotate around the threaded rod 301, while driving the collar 305 connected to the threaded rod 301 to rotate, and the scraper plate 306 at the bottom of the collar 305 rotates with the collar 305, and the scraper plate 306 scrapes the material from the feeding capillary at the bottom of the internal tank body 201 to clean up the attached material to avoid waste. As the first connecting rod 202 on the bottom surface moves downward, when the first connecting rod 202 penetrates and slides to contact the first protrusion 303 on the upper surface of the bottom plate 302, the groove of the first connecting rod 202 engages and slides with the first protrusion 303, and the first connecting rod 202 vibrates, causing the internal tank body 201 to vibrate, so that the material attached to the inner wall of the internal tank body 201 can fall off, preventing the material from piling up and adhering, maintaining the efficient operation state of the equipment, and at the same time helping to clean the dust accumulated on the external tank body 102 and the internal tank body 201;

[0038] Before the material falls, the receiving barrel 407 is pushed to the bottom of the base 101, and the arc-shaped baffle plate 411 prepares the receiving barrel 407 to be placed under the barrel cover ring 406, ensuring that the barrel cover ring 406 is completely matched with the receiving barrel 407 when it falls. When the tilt angle of the hinged rod 203 is deflected, the third connecting rod 401 is forced to move downward, and the special-shaped plate 405 is affected by the hinge axis at the bottom of the third connecting rod 401. The special-shaped plate 405 begins to deflect, and the connecting rod on one side of the special-shaped plate 405 slides with the discharge pipe 5, and the barrel cover ring 406 moves downward. The second protrusions 409 on both sides of the fixed block 408 slide with the third protrusions 410 on the inner wall of the barrel cover ring 406. When the second protrusion 409 slides to above the third protrusion 410, the barrel cover ring 406 is completely matched with the receiving barrel 407, completing the sealing work, so that the material will not splash when it is discharged, and the material will not be blown away by the wind. When the tilt angle is reset to its original position, the third connecting rod 401 moves upward, and the barrel cover ring 406 moves with it. At this time, the material receiving barrel 407 is slightly pulled up. Under the effect of gravity, the second protrusion 409 slides downward, and the material receiving barrel 407 is dropped to a distant place. The fourth connecting rod 402 on the outer surface of the third connecting rod 401 moves accordingly, and the arc-shaped baffle 411 connected to the fourth connecting rod 402 slides on the outer surface of the material receiving barrel 407. When the material receiving barrel 407 is dropped, it is ensured that the material receiving barrel 407 is dropped to its original position. The leak-proof device 4 can effectively reduce the possibility of dust leakage to the surrounding environment, protect the surrounding air, reduce the material concentration in the workplace, improve the operator's working environment and air quality, help reduce occupational health problems, improve the safety of the staff, and at the same time reduce the waste caused by material leakage, effectively save costs and improve production efficiency.
