Description
Technical Field
[0001] The invention relates to the technical field of PVC foam board feeding, in particular to a powder material silo capable of buffering the feeding of the PVC foam board and an operating method thereof. Background Art
[0002] A PVC buffered powder silo is a special structural component installed at the bottom of the powder silo during the feeding process of PVC foam board production. It connects to the feeding equipment. Its core function is to balance pressure fluctuations during material discharge by providing a buffer space or buffering device. This prevents feeding anomalies caused by material accumulation, bridging, or uneven flow rates, thereby ensuring stability in the subsequent extrusion process.
[0003] A buffer device for powdered materials in a silo is disclosed in the Chinese invention patent application publication number CN202880505U. Although the above device can effectively weaken the impact of materials on the subsequent equipment when the powder silo is unloaded, and enhance the stability of the feeding of the subsequent equipment, even when the material level in the silo is low, the feeding process has almost no negative effect. The device solves the problem of the influence of the powdered material feeding process on the metering and feeding of the subsequent equipment from a technical point of view, but the above device is not provided with a disintegrating device. The powder still falls in a pile shape during the falling process, and the speed is fast, which cannot make time for the production machine to process the powder. After the powder being processed and the unprocessed powder are mixed, the final production may be affected. The product fails to meet the production qualification requirements, which in turn affects the production quality of the product to a certain extent; the above-mentioned device is not provided with a dedicated connection method with the production machine, which requires the above-mentioned device to be connected to the production machine by manual spot welding. However, the existing spot welding has a small welding area, which makes the device easy to desolder after long-term use. The desoldered device is very likely to be separated from the production machine, which may affect normal production and is more likely to cause casualties. At the same time, manual spot welding also increases the production cost of the factory to a certain extent. Therefore, the present application provides a powder feeding port with buffering for PVC foam board and an operation method to meet the needs. Summary of the Invention
[0004] (1) Technical problems solved In response to the deficiencies in the prior art, the present invention provides a powder hopper with a buffered feeding port for PVC foam boards and an operating method, which solves the problems that the powder in the above-mentioned device falls in piles at a fast speed, cannot free up sufficient production time for the manufacturing machine, and the powder being processed and the unprocessed powder may be mixed, resulting in the produced products failing to meet the production qualification requirements, affecting product quality; and the above-mentioned device is not provided with a dedicated connection method for connecting with the machine, so that the device relies on manual spot welding to connect with the machine, which to a certain extent increases the factory's production costs. Long-term use of the spot-welded device may cause the device to separate from the machine, thereby affecting normal production. At the same time, the separation of the device from the machine may also cause certain casualties.

[0014] The method for operating the buffered powder silo for feeding PVC foam board comprises the following steps: Step 1. The powder of the PVC foam board is transported to the feed plate cover through the feed pipe, and finally enters the receiving port of the top breaking up module, and then the powder falls onto the powder receiving plate on the surface of the top first rotating rod and the top second rotating rod through the feeding end. However, before the feeding procedure is carried out, it is necessary to start the top servo motor, and the rotor in the top servo motor rotates, which in turn drives the top third rotating rod to start rotating. When the top third rotating rod rotates, it drives the top first gear to rotate, and the rotation of the top first gear will drive the top second gear engaged with it to rotate in the opposite direction, and the rotation of the top first gear and the top second gear will drive the corresponding top first rotating rod and The second rotating rod on the top rotates in the opposite direction, and the feeding program is started at this time. After the powder is dropped, the powder falls in piles. Because the first rotating rod and the second rotating rod on the top rotate, the powder receiving plates on their surfaces will break up the piled powder and also receive part of the powder. The received powder will be slowly sprinkled into the bottom breaking module. The main function of this module is to preliminarily break up the piled powder, break up the large block powder into smaller block powder, and slowly sprinkle it into the bottom breaking module. Breaking up the piled block powder into small block powder can delay the falling time of the powder to a certain extent. This module serves as a preliminary buffer to complete the operation. Step 2: Before the piles of large lumps of powder are broken up into small pieces by the top breaking up module and slowly fall into the bottom breaking box of the bottom breaking up module, it is necessary to start the bottom servo motor. At this time, the rotor in the bottom servo motor rotates, which in turn drives the second short rod at the bottom to rotate, thereby driving the left groove wheel and the first short rod at the bottom to rotate. When the left groove wheel rotates, the left groove wheel at this time drives the right groove wheel to rotate through the belt, and then drives the fourth short rod at the bottom to rotate. The rotation of the first short rod at the bottom will drive the first gear at the bottom to rotate, and the rotation of the first gear at the bottom will drive the second gear at the bottom meshing with it to rotate, and the rotation of the fourth short rod at the bottom will drive the third gear at the bottom to rotate, and the rotation of the third gear at the bottom will drive the fourth gear at the bottom meshing with it to rotate. At this time, the first gear at the bottom and the second gear at the bottom move in opposite directions, and the third gear at the bottom and the fourth gear at the bottom move in opposite directions. The rotation of the first gear at the bottom, the second gear at the bottom, the third gear at the bottom and the fourth gear at the bottom will respectively drive the corresponding first rotating rod at the bottom, the second rotating rod at the bottom, the third rotating rod at the bottom and the fourth rotating rod at the bottom to rotate. At this time, the scattering plate on the surface will also rotate. At this time, after the small pieces of powder fall into the bottom scattering box, the small pieces of powder will be further scattered by the scattering plate. After the small pieces of powder are scattered again in this module, the powder will basically be broken into granules, and the granular powder will fall into the powder chasing module. This module breaks up the small pieces of powder into granules. Because the granular powder is lighter, its falling time is slower, so as to better control the falling time, and make enough time for the PVC foam board making machine to make PVC foam board, and reduce the powder body falling into the machine too early, resulting in poor quality of the PVC foam board. This module is the second layer of buffering to complete the operation; Step 3: The granular powder body falls from the bottom breaking module and enters the powder chasing box. When the granular powder particles are small, the particles will fall directly from the dense mesh screen, and when the granular powder particles are large, the powder will be isolated on the dense mesh screen. At this time, the user needs to start the cylinder. After the cylinder is started, the gas rod on the cylinder will be driven to move horizontally. When the gas rod on the cylinder will drive the push-pull plate to move horizontally, when the push-pull plate moves horizontally, it will pull the slide to move horizontally back and forth. The pulley on the slide is provided to make the slide move more smoothly in the chute. When the slide moves in the chute, the powder chasing roller will also roll. The rolling of the powder chasing roller will press the larger granular powder on the dense mesh screen into smaller granular powder, and pass through the dense mesh screen into the PVC foam board production machine to complete the operation. Step 4. When the device needs to be connected to the PVC foam board production machine, the user needs to place the heating welding rod into the inner wall of the sleeve, and then place the PVC foam board production machine into the sleeve. At this time, the PVC foam board production machine is also placed in the heating welding rod. When the heating welding rod is firmly fixed between the PVC foam board production machine and the sleeve, the user clamps the existing welding splint to the connecting ring. At this time, the welding machine will convert electricity into heat, and a large amount of heat will enter the heating welding rod through the heating connecting line. After the heating welding rod is heated, the heating welding rod will be directly welded between the sleeve and the PVC foam board production machine, thereby connecting the device and the PVC foam board production machine together to complete the operation.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up the top breaking up module and the bottom breaking up module, the device can break up the piled powder into granules, so that the powder falls more slowly, thereby providing more time for the production machine to process the powder. At the same time, because the powder falls slowly after the breaking up process, the powder in the production machine can be better processed, which reduces the possibility of the products produced not meeting the production qualification requirements to a certain extent, and also guarantees the quality of the products produced to a certain extent, and also guarantees the buffering effect of the piled powder of the device to a certain extent.
[0016] By setting up a welding installation module, when the device is connected to the manufacturing machine, the area where the gunpowder is connected to the two is larger, the connection effect is better than that of spot welding, the connection is safer, and it is not easy to become unsoldered after long-term use. This can ensure the normal progress of production to a certain extent, and also ensure the personal safety of surrounding personnel to a certain extent. At the same time, the module does not require manual welding, which also reduces the production cost of the factory to a certain extent.
[0017] In summary, the present invention has the ability to break up heaped powder into fine particles, thereby slowing down the powder's descent rate and providing sufficient processing time for the manufacturing machine, thereby ensuring the quality of finished product production and the connection between the device and the manufacturing machine without manual spot welding, reducing the factory's production expenses for manual spot welding. At the same time, the welding area of the welding powder is larger, and the connection between the device and the machine is more secure, thereby ensuring the normal production of the machine and the personal safety of the workers.

Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0024] During use, the powder passes through the feeding pipe 1 and the feeding plate cover 2 into the top breaking up module 3. After entering the top breaking up module 3, the piled powder will be preliminarily broken up by the top breaking up module 3, so that the piled large pieces of powder are broken up into small pieces of powder. This is the initial buffering, and the small pieces of powder will enter the bottom breaking up module 4. At this moment, the small pieces of powder will continue to be broken up into granules in the bottom breaking up module 4. The granular powder is light in weight and falls slowly, which can free up more time for the production machine. This is the second layer of buffering. After the granular powder falls, the smaller granular powder will fall from the powder grinding module 5, but the larger granular powder will remain on the powder grinding module 5. After being ground and crushed by the powder grinding module 5, it becomes smaller granular powder and then falls from the powder grinding module 5.

The received powder will be slowly sprinkled into the bottom breaking module 4. The main function of this module is to preliminarily break up the piles of powder, break up the large block powder into smaller block powder, and slowly sprinkle it into the bottom breaking module 4.

[0034] The first short rod 412 at the bottom is welded to the first rotating rod 406 at the bottom, and the left groove wheel 413 is welded between the first short rod 412 at the bottom and the second short rod 414 at the bottom, the third short rod 418 at the bottom is welded to the second gear 417 at the bottom, the fourth short rod 421 at the bottom is welded between the third gear 422 at the bottom and the right groove wheel 420, and the fifth short rod 424 at the bottom is welded to the fourth gear 423 at the bottom, the belt 419 is put between the left groove wheel 413 and the right groove wheel 420, the bottom servo motor base 416 is welded to the bottom broken box body 401, and the bottom servo motor base 416 is welded to the bottom broken box body 401. The servo motor 415 is installed on the second short rod 414 at the bottom. At this moment, the bottom servo motor 415 is located on the bottom servo motor base 416. The bottom first gear 411, the bottom second gear 417, the bottom third gear 422 and the bottom fourth gear 423 are installed in the bottom broken-up box body 401, and the bottom first short rod 412, the bottom third short rod 418, the bottom fourth short rod 421 and the bottom fifth short rod 424 are respectively adapted to the bottom first rotating shaft 402, the bottom second rotating shaft 403, the bottom third rotating shaft 404 and the bottom fourth rotating shaft 405 to complete the assembly.
[0035] Before the piled-up large lumps of powder are broken up into small pieces by the top breaking module 3 and slowly fall into the bottom breaking box 401 of the bottom breaking module 4, it is necessary to start the bottom servo motor 415. At this time, the rotor in the bottom servo motor 415 rotates, which in turn drives the second short rod 414 at the bottom to rotate, thereby driving the left groove wheel 413 and the first short rod 412 at the bottom to rotate. When the left groove wheel 413 rotates, the left groove wheel 413 at this time drives the right groove wheel 420 to rotate through the belt 419, thereby driving the fourth short rod 414 at the bottom to rotate. The rod 421 rotates, and the first short rod 412 at the bottom rotates, which drives the first gear 411 at the bottom to rotate. The rotation of the first gear 411 at the bottom drives the second gear 417 at the bottom that is meshed with it to rotate. The rotation of the fourth short rod 421 at the bottom drives the third gear 422 at the bottom to rotate. The rotation of the third gear 422 at the bottom drives the fourth gear 423 at the bottom that is meshed with it to rotate. At this time, the first gear 411 at the bottom and the second gear 417 at the bottom move in opposite directions, and the third gear 422 at the bottom and the fourth gear 423 at the bottom move in opposite directions. The rotation of the first gear 411, the second gear 417, the third gear 422 and the fourth gear 423 will respectively drive the corresponding first rotating rod 406, the second rotating rod 407, the third rotating rod 408 and the fourth rotating rod 409 to rotate. At this time, the scattering plate 410 on the surface will also rotate. At this time, after the small pieces of powder fall into the bottom scattering box 401, the small pieces of powder will be further scatter by the scattering plate 410, and the small pieces of powder will be scattering in the mold. After the blocks are broken up again, the powder will basically be broken into granules, and the granular powder will fall into the powder chasing module 5. This module breaks up the small blocks of powder into granules. Because the granular powder is lighter, its falling time is slower, so the falling time can be better controlled, which makes enough time for the PVC foam board making machine to make PVC foam boards, and reduces the powder falling into the machine too early, resulting in poor quality of the PVC foam board. This module is the second layer of buffering to complete the operation.
[0036] By setting up the top breaking up module 3 and the bottom breaking up module 4, the device can break up the piled powder into granules, so that the speed at which the powder falls becomes slower, thereby providing more time for the manufacturing machine to process the powder. At the same time, because the powder after the breaking up process falls more slowly, the powder in the manufacturing machine can be better processed, which to a certain extent reduces the possibility that the products produced will not meet the production qualification requirements, and also to a certain extent guarantees the quality of the products produced, and also to a certain extent guarantees the buffering effect of the piled powder of the device.

The inner wall of the threaded ring 507 is threadedly connected to the cylinder 508, and the side of the cylinder 508 is fixedly connected to the C-shaped plate 509. The cylinder 508 is fixedly connected to the powder chasing box body 501 through the C-shaped plate 509. A push-pull plate groove is provided on the front of the powder chasing box body 501. The push-pull plate groove and the push-pull plate 506 are adapted to each other, and a dense mesh filter 510 is fixedly connected to the bottom of the powder chasing box body 501.
[0039] The powder chasing box body 501 is welded to the bottom of the bottom breaking box body 401 of the bottom breaking module 4, slide the slide 503 into the slide groove 502, pass the push-pull plate 506 through the push-pull plate groove of the powder chasing box body 501, and then install it on the slide 503 through the push-pull plate bolts, and the pulley 504 and the slide 503 are connected as one body, install the powder chasing roller 505 into the roller hole of the slide 503, and weld the threaded ring 507 to the push-pull plate 506. When the cylinder 508 and the C-shaped plate 509 are not welded together, first screw the cylinder 508 onto the threaded ring 507, wait for the cylinder 508 to be fixed on the threaded ring 507, and then use the welding technology to weld the C-shaped plate 509 between the cylinder 508 and the powder chasing box body 501, and the fine mesh filter 510 is welded to the bottom of the powder chasing box body 501 to complete the assembly.
[0040] The granular powder body falls from the bottom breaking module 4 and enters the powder chasing box body 501. When the granular powder particles are small, the particles will fall directly from the dense mesh filter 510, and when the granular powder particles are large, the powder will be isolated on the dense mesh filter 510. At this time, the user needs to start the cylinder 508. After the cylinder 508 is started, the air rod on the cylinder 508 will be driven to move horizontally. When the air rod on the cylinder 508 drives the push-pull plate 506 to move horizontally, the push-pull plate When 506 makes horizontal movement, it will pull the slider 503 to make horizontal movement back and forth. The pulley 504 is set on the slider 503 to make the slider 503 move more smoothly in the chute 502. When the slider 503 moves in the chute 502, the powder roller 505 will also roll. The rolling of the powder roller 505 will press the larger granular powder on the dense mesh filter 510 into smaller granular powder, and enter the PVC foam board production machine through the dense mesh filter 510 to complete the operation.
[0041] Implementation 4, such as Figure 6 As shown, in this embodiment, the welding installation module 6 includes a machine connection box body 601, the bottom of the machine connection box body 601 is fixedly connected to an expansion plate 602, the bottom of the expansion plate 602 is fixedly connected to a sleeve plate 603, the inner wall of the sleeve plate 603 is installed with a heating welding rod 604, the bottom of the heating welding rod 604 is provided with a heating connecting wire 605, and the bottom of the heating connecting wire 605 is provided with a connecting ring 606.
[0042] The machine connection box body 601 is welded to the bottom of the powder chasing box body 501 of the powder chasing module 5, the expansion plate 602 is welded to the bottom of the machine connection box body 601, the sleeve plate 603 is welded to the bottom of the expansion plate 602, the heating welding rod 604 is placed between the sleeve plate 603 and the manufacturing machine, and the heating connecting wire 605 and the heating welding rod 604 are connected as a whole, and the connecting ring 606 and the heating connecting wire 605 are connected as a whole to complete the assembly.
[0043] When the device needs to be connected to the PVC foam board production machine, the user needs to place the heating welding rod 604 into the inner wall of the sleeve plate 603, and then place the PVC foam board production machine into the sleeve plate 603. At this time, the PVC foam board production machine is also placed in the heating welding rod 604. When the heating welding rod 604 is firmly fixed between the PVC foam board production machine and the sleeve plate 603, the user clamps the existing welding clamp to the connecting ring 606. At this time, the welding machine will convert electricity into heat, and a large amount of heat will enter the heating welding rod 604 through the heating connecting line 605. After the heating welding rod 604 is heated, the heating welding rod 604 will be directly welded between the sleeve plate 603 and the PVC foam board production machine, thereby connecting the device and the PVC foam board production machine together to complete the operation.
[0044] By setting up the welding installation module 6, when the device is connected to the production machine, the area where the gunpowder is connected to the two is larger, the connection effect is better than that of spot welding, the connection is safer, and it is not easy to become unsoldered after long-term use. This can ensure the normal progress of production to a certain extent, and also ensure the personal safety of surrounding personnel to a certain extent. At the same time, the module does not require manual welding, which also reduces the production cost of the factory to a certain extent.
[0045] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.
[0046] A method for operating a powder material silo with buffered feeding for PVC foam board comprises the following steps when in use; Step 1: The powder of the PVC foam board is transported to the feed plate cover 2 through the feed pipe 1, and finally enters the receiving port 301 of the top scattering module 3, and then the powder falls onto the powder receiving plate 309 on the surface of the top first rotating rod 307 and the top second rotating rod 308 through the feed end 303. However, before the feeding procedure is carried out, it is necessary to start the top servo motor 313, and the rotor in the top servo motor 313 rotates, which in turn drives the top third rotating rod 312 to start rotating. When the top third rotating rod 312 rotates, it will drive the top first gear 310 to rotate, and the rotation of the top first gear 310 will drive the top second gear 311 meshing with it to rotate in the opposite direction, and the rotation of the top first gear 310 and the top second gear 311 The powder receiving plates 309 on the top of the powder receiving plate 308 are used to break up the powder in the piles, and the powder receiving plates 309 on the top of the powder receiving plate 308 are used to catch some of the powder. The caught powder will be slowly scattered into the bottom breaking module 4. The main function of this module is to break up the piles of powder and break up the large block powder into smaller block powder, which will be slowly scattered into the bottom breaking module 4. Breaking up the piles of block powder into small pieces can delay the falling time of the powder to a certain extent. This module serves as a preliminary buffer to complete the operation. Step 2: Before the piled-up large lumps of powder are broken up into small lumps of powder by the top breaking module 3 and slowly fall into the bottom breaking box 401 of the bottom breaking module 4, it is necessary to start the bottom servo motor 415. At this time, the rotor in the bottom servo motor 415 rotates, which in turn drives the second short rod 414 at the bottom to rotate, thereby driving the left groove wheel 413 and the first short rod 412 at the bottom to rotate. When the left groove wheel 413 rotates, the left groove wheel 413 at this time drives the right groove wheel 420 to rotate through the belt 419, thereby driving the bottom second short rod 414 to rotate. The fourth short rod 421 rotates, and the first short rod 412 at the bottom rotates, which drives the first gear 411 at the bottom to rotate. The rotation of the first gear 411 at the bottom drives the second gear 417 at the bottom that is meshed with it to rotate. The rotation of the fourth short rod 421 at the bottom drives the third gear 422 at the bottom to rotate. The rotation of the third gear 422 at the bottom drives the fourth gear 423 at the bottom that is meshed with it to rotate. At this time, the first gear 411 at the bottom and the second gear 417 at the bottom move in opposite directions, and the third gear 422 at the bottom and the fourth gear 423 at the bottom move in opposite directions. The rotation of the first gear 411, the second gear 417, the third gear 422 and the fourth gear 423 will respectively drive the corresponding first rotating rod 406, the second rotating rod 407, the third rotating rod 408 and the fourth rotating rod 409 to rotate. At this time, the scattering plate 410 on the surface will also rotate. At this time, after the small pieces of powder fall into the bottom scattering box 401, the small pieces of powder will be further scatter by the scattering plate 410, and the small pieces of powder will be scattering in the mold. After the blocks are broken up again, the powder will basically be broken into granules, and the granular powder will fall into the powder chasing module 5, which breaks up the small blocks of powder into granules. Because the granular powder is lighter, its falling time is slower, so the falling time is better controlled, which makes enough time for the PVC foam board making machine to make PVC foam boards, and reduces the powder falling into the machine too early, resulting in low quality of the PVC foam board. This module is the second layer of buffering to complete the operation; Step 3: The granular powder body falls from the bottom scattering module 4 and enters the powder chasing box body 501. When the granular powder particles are small, the particles will fall directly from the dense mesh filter 510, and when the granular powder particles are large, the powder will be isolated on the dense mesh filter 510. At this time, the user needs to start the cylinder 508. After the cylinder 508 is started, the air rod on the cylinder 508 will be driven to move horizontally. When the air rod on the cylinder 508 drives the push-pull plate 506 to move horizontally, the push When the pull plate 506 makes a horizontal movement, it pulls the slider 503 to make a horizontal movement back and forth. The pulley 504 is provided on the slider 503 to make the slider 503 move more smoothly in the chute 502. When the slider 503 moves in the chute 502, the powder roller 505 also rolls. The rolling of the powder roller 505 presses the larger granular powder on the dense mesh filter 510 into smaller granular powder, which then passes through the dense mesh filter 510 and enters the PVC foam board production machine to complete the operation. Step 4. When the device needs to be connected to the PVC foam board production machine, the user needs to place the heating welding rod 604 into the inner wall of the sleeve plate 603, and then place the PVC foam board production machine into the sleeve plate 603. At this time, the PVC foam board production machine is also placed in the heating welding rod 604. When the heating welding rod 604 is firmly fixed between the PVC foam board production machine and the sleeve plate 603, the user clamps the existing welding clamp to the connecting ring 606. At this time, the welding machine will convert electricity into heat, and a large amount of heat will enter the heating welding rod 604 through the heating connecting line 605. After the heating welding rod 604 is heated, the heating welding rod 604 will be directly welded between the sleeve plate 603 and the PVC foam board production machine, thereby connecting the device and the PVC foam board production machine to complete the operation.
[0047] The technical solution provided by the present invention is as follows: the powder of the PVC foam board is transported to the feed plate cover 2 through the feed pipe 1, and finally enters the receiving port 301 of the top scattering module 3, and then the powder falls onto the powder receiving plate 309 on the surface of the top first rotating rod 307 and the top second rotating rod 308 through the feed end 303. However, before the feeding procedure is carried out, it is necessary to start the top servo motor 313, and the rotor in the top servo motor 313 rotates, which in turn drives the top third rotating rod 312 to start rotating. When the top third rotating rod 312 rotates, it drives the top first gear 310 to rotate, and the rotation of the top first gear 310 drives the top second gear 311 meshed with it to rotate in the opposite direction, and the top first gear 310 and the top second The rotation of the gear 311 will drive the corresponding top first rotating rod 307 and the top second rotating rod 308 to rotate in opposite directions. At this time, the feeding program is started. After the powder is dropped, the powder falls in piles. Because the top first rotating rod 307 and the top second rotating rod 308 rotate, the powder receiving plates 309 on their surfaces will break up the piles of powder and also take over part of the powder. The taken-over powder will be slowly sprinkled into the bottom breaking module 4. The main function of this module is to preliminarily break up the piles of powder, break up the huge block powder into smaller block powder, and slowly sprinkle it into the bottom breaking module 4. Breaking up the piles of block powder into small pieces of block powder can delay the falling time of the powder to a certain extent. Before the powder is broken up into small pieces by the top breaking module 3 and slowly falls into the bottom breaking box body 401 of the bottom breaking module 4, it is necessary to start the bottom servo motor 415. At this time, the rotor in the bottom servo motor 415 rotates, which in turn drives the second short rod 414 at the bottom to rotate, thereby driving the left groove wheel 413 and the first short rod 412 at the bottom to rotate. When the left groove wheel 413 rotates, the left groove wheel 413 at this time drives the right groove wheel 420 to rotate through the belt 419, and then drives the fourth short rod 421 at the bottom to rotate. The rotation of the first short rod 412 at the bottom will drive the first gear 411 at the bottom to rotate. The rotation of the first gear 411 at the bottom will drive the second gear 417 at the bottom meshing with it to rotate, and the second gear 417 at the bottom will rotate. The rotation of the four short rods 421 will drive the third gear 422 at the bottom to rotate, and the rotation of the third gear 422 at the bottom will drive the fourth gear 423 at the bottom to rotate. At this time, the first gear 411 at the bottom and the second gear 417 at the bottom move in opposite directions, and the third gear 422 at the bottom and the fourth gear 423 at the bottom move in opposite directions. The rotation of the first gear 411 at the bottom, the second gear 417 at the bottom, the third gear 422 at the bottom and the fourth gear 423 at the bottom will respectively drive the corresponding first rotating rod 406 at the bottom, the second rotating rod 407 at the bottom, the third rotating rod 408 at the bottom and the fourth rotating rod 409 at the bottom to rotate. At this time, the scattering plate 410 on its surface will also rotate. At this time, after the small pieces of powder fall into the bottom scattering box 401,The small pieces of powder will be further broken up by the breaking plate 410. After the small pieces of powder are broken up again in this module, the powder will basically be broken into granules, and the granular powder will fall into the powder-beating module 5. This module breaks up the small pieces of powder into granules. Because the granular powder is lighter, its falling time is slower, so the falling time can be better controlled, which makes enough time for the PVC foam board making machine to make PVC foam boards, reduces the powder falling into the machine too early, and causes the quality of the PVC foam board to be low. The granular powder falls from the bottom breaking module 4. And enter the powder chasing box body 501. When the granular powder particles are small, the particles will fall directly from the dense mesh filter 510. When the granular powder particles are large, the powder will be isolated on the dense mesh filter 510. At this time, the user needs to start the cylinder 508. After the cylinder 508 is started, the gas rod on the cylinder 508 will be driven to move horizontally. When the gas rod on the cylinder 508 drives the push-pull plate 506 to move horizontally, when the push-pull plate 506 moves horizontally, it will pull the slider 503 to move back and forth horizontally. The pulley 504 is provided on the slider 503 to enable the slider 503 to move horizontally when The movement in the chute 502 is smoother. When the slider 503 moves in the chute 502, the powder roller 505 will also roll. The rolling of the powder roller 505 will press the larger granular powder on the dense mesh filter 510 into smaller granular powder, and enter the PVC foam board production machine through the dense mesh filter 510. When the device needs to be connected to the PVC foam board production machine, the user needs to put the heating electrode 604 into the inner wall of the sleeve 603, and then put the PVC foam board production machine into the sleeve 603. At this time, the PVC foam The board production machine is also placed inside the heating electrode 604. When the heating electrode 604 is firmly fixed between the PVC foam board production machine and the sleeve 603, the user then clamps the existing welding clamp onto the connecting ring 606. The welding machine then converts electricity into heat, and a large amount of this heat enters the heating electrode 604 through the heating connecting wire 605. After being heated, the heating electrode 604 is directly welded between the sleeve 603 and the PVC foam board production machine, thereby connecting the device and the PVC foam board production machine together.
[0048] Supplementary explanation of the evaluation criteria and specific methods of the disintegration effect: Evaluation criteria: Particle size distribution: This is the most intuitive criterion for evaluating the disintegration effect. Sieve analysis or laser particle size analyzer can be used to measure the particle size distribution curve of the powder to understand the particle size range, average particle size, particle size distribution uniformity and other information of the powder; Bulk density: The bulk density of the powder after breaking up can reflect the fluidity of the powder. The smaller the bulk density, the better the fluidity of the powder, and the easier it is to be evenly processed by subsequent equipment; Flowability: The flow angle, repose angle and other indicators can be used to evaluate the flowability of powders. The smaller the flow angle and the repose angle, the better the flowability of the powder; Bridging phenomenon: Observe whether the powder after being dispersed is prone to bridging phenomenon, that is, whether the powder is prone to form an arched structure when piled up, affecting the fluidity of the powder; Evaluation Methodology: Sieving analysis: The powder is sieved through a series of standard sieves, and the mass of the powder on each sieve is counted to obtain the particle size distribution curve of the powder; Laser particle size analyzer: uses a laser beam to illuminate the powder and analyzes the optical signal of laser scattering or diffraction to obtain the particle size distribution information of the powder; Bulk density measurement: Place a certain amount of powder into a graduated cylinder, measure the volume and mass of the powder, and then calculate the bulk density; Flowability test: The flow angle or repose angle of the powder can be measured using equipment such as a flow angle tester or an angle of repose tester; Observation of bridging phenomenon: Pile the powdered material into a tilted container and observe whether it can easily form an arched structure. Data analysis and conclusions: Based on the collected data, statistical analysis is performed and compared with the un-dispersed powder to draw conclusions on the effectiveness of the dispersing module. For example, the effect of the powder dispersing can be analyzed to see whether the particle size distribution of the powder is more uniform, whether the bulk density is reduced, whether the fluidity is improved, and whether the bridging phenomenon is reduced. Experimental plan suggestions: Set up a control group: When conducting an experiment, it is recommended to set up a control group with unbroken powder for comparative analysis; Choose appropriate experimental equipment: Choose appropriate experimental equipment according to needs, such as screening analysis equipment, laser particle size analyzer, flow angle tester, etc.; Control experimental conditions: When conducting experiments, it is necessary to control experimental conditions, such as the type of powder, moisture content, experimental environment, etc., to ensure the reliability of the experimental results; Conduct multiple experiments: To obtain more reliable data, it is recommended to conduct multiple experiments and calculate the average value.
[0049] Buffering effect evaluation method: Powder flow fluctuation: The buffering effect can be evaluated by measuring the change of powder flow over time. For example, the fluctuation amplitude of powder flow at different time points can be measured. The smaller the fluctuation amplitude, the better the buffering effect. Equipment load changes: Buffering effectiveness can be assessed by measuring changes in production equipment load. For example, you can measure how parameters like equipment power and current change over time. Smaller changes indicate better buffering effectiveness.
[0050] Product quality stability: The cushioning effect can be evaluated by measuring the stability of product quality. For example, the fluctuation range of parameters such as product thickness, density, and bubble content can be measured. The smaller the fluctuation range, the better the cushioning effect. Impact on production equipment: Extend equipment service life: By cushioning the impact of powder, it can reduce wear and damage to production equipment, thereby extending the service life of the equipment; Improve equipment operation stability: By stabilizing the flow of powder, the operation stability of production equipment can be improved, and equipment failures and downtime can be reduced; Reduce energy consumption: By optimizing the powder conveying process, the energy consumption of the equipment can be reduced, thereby reducing production costs; Improvement of product quality: Improve product quality stability: By buffering the impact of powder and flow fluctuations, the stability of product quality can be improved, product defects can be reduced, and the product qualification rate can be increased; Improve product consistency: By optimizing the powder delivery process, product consistency can be improved and the fluctuation range of product performance can be reduced; Improve product appearance quality: By optimizing the powder conveying process, product surface defects can be reduced and product appearance quality can be improved.
[0051] Regarding the quantitative explanation of the slowdown in the falling speed of powder, the following experimental data and theoretical analysis are supplemented: Supplementary experimental data Drop speed comparison test (tabular format) Test conditions Falling speed (m / s) Speed reduction rate (%) Test Method Unbroken original powder 1.25±0.15 - High-speed camera tracking method After the first level is broken up 0.85±0.08 32% Laser speed meter After the second level is broken up 0.62±0.05 50% Photoelectric sensor array Typical working condition test data: When the moisture content of the powder is 5%, the three-stage disintegration can reduce the falling speed from 1.2m / s to 0.55m / s (a decrease of 54%).

10. The method for operating a powder silo with buffered feeding of PVC foam board according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: The powder of the PVC foam board is transported to the feed plate cover (2) through the feed pipe (1), and finally enters the receiving port (301) of the top scattering module (3), and then the powder falls onto the powder receiving plate (309) on the surface of the top first rotating rod (307) and the top second rotating rod (308) through the feed end (303). However, before the feeding process is carried out, it is necessary to start the top servo motor (313). The rotor in the top servo motor (313) rotates, and then drives the top third rotating rod (312) to start rotating. When the top third rotating rod (312) rotates, it drives the top first gear (310) to rotate, and the top first gear (310) rotates, which drives the top second gear (311) meshed with it to rotate in the opposite direction, and the top first gear (310) and the top second gear (311) rotate in the opposite direction. The rotation of the gear (311) drives the corresponding top first rotating rod (307) and the top second rotating rod (308) to rotate in opposite directions. At this time, the feeding program is started. After the powder is dropped, the powder falls in piles. Because the top first rotating rod (307) and the top second rotating rod (308) rotate, the powder receiving plate (309) on their surface will break up the piled powder and also receive part of the powder. The received powder will be slowly sprinkled into the bottom breaking module (4). The main function of this module is to preliminarily break up the piled powder, break up the large block powder into smaller block powder, and slowly sprinkle it into the bottom breaking module (4). Breaking up the piled block powder into small pieces of block powder can delay the falling time of the powder to a certain extent. This module serves as a preliminary buffer to complete the operation. Step 2: Before the piled large lumps of powder are broken up into small lumps of powder by the top breaking module (3) and slowly fall into the bottom breaking box (401) of the bottom breaking module (4), it is necessary to start the bottom servo motor (415). At this time, the rotor in the bottom servo motor (415) rotates, which in turn drives the second short rod (414) at the bottom to rotate, thereby driving the left groove wheel (413) and the first short rod (412) at the bottom to rotate. When the left groove wheel (413) rotates, the left groove wheel (413) drives the right groove wheel (420) to rotate through the belt (419), thereby driving the fourth short rod (414) at the bottom to rotate. The short rod (421) rotates, and the first short rod (412) at the bottom rotates, which drives the first gear (411) at the bottom to rotate. The rotation of the first gear (411) at the bottom drives the second gear (417) at the bottom that is meshed with it to rotate. The rotation of the fourth short rod (421) at the bottom drives the third gear (422) at the bottom to rotate. The rotation of the third gear (422) at the bottom drives the fourth gear (423) at the bottom that is meshed with it to rotate. At this time, the first gear (411) at the bottom and the second gear (417) at the bottom move in opposite directions, and the third gear (422) at the bottom and the fourth gear (423) at the bottom move in opposite directions. The rotation of the first gear (411), the second gear (417), the third gear (422) and the fourth gear (423) will respectively drive the corresponding first rotating rod (406), the second rotating rod (407), the third rotating rod (408) and the fourth rotating rod (409) to rotate. At this time, the scattering plate (410) on the surface will also rotate. At this time, after the small pieces of powder fall into the bottom scattering box (401), the small pieces of powder will be further scatter by the scattering plate (410). After the block-shaped powder material is broken up again in this module, the powder material material will basically be broken into granules, and the granular powder material will float into the powder-beating module (5). This module breaks up the small block-shaped powder material into granules. Because the granular powder material is lighter, its falling time is slower, thereby better controlling the falling time, freeing up enough time for the PVC foam board making machine to make PVC foam boards, and reducing the powder material material from falling into the machine too early, resulting in low quality of the PVC foam board. This module is the second layer of buffering to complete the operation; Step 3: The granular powder body falls from the bottom scattering module (4) and enters the powder chasing box body (501). When the granular powder particles are small, the particles will directly fall from the dense mesh filter (510), and when the granular powder particles are large, the powder will be isolated on the dense mesh filter (510). At this time, the user needs to start the cylinder (508). After the cylinder (508) is started, the air rod on the cylinder (508) will be driven to move horizontally. When the air rod on the cylinder (508) drives the push-pull plate (506) to move horizontally, the push-pull plate (506) will also move horizontally. When the slider (506) makes a horizontal movement, it pulls the slider (503) to make a horizontal movement forward and backward. The pulley (504) is provided on the slider (503) to make the slider (503) move more smoothly in the chute (502). When the slider (503) moves in the chute (502), the powder roller (505) will also roll. The powder roller (505) rolls and presses the larger granular powder on the dense mesh filter (510) into smaller granular powder, and enters the PVC foam board production machine through the dense mesh filter (510) to complete the operation. Step 4: When the device needs to be connected to the PVC foam board production machine, the user needs to place the heating welding rod (604) into the inner wall of the sleeve (603), and then place the PVC foam board production machine into the sleeve (603). At this time, the PVC foam board production machine is also placed in the heating welding rod (604). When the heating welding rod (604) is firmly fixed between the PVC foam board production machine and the sleeve (603), the user clamps the existing welding clamp to the connecting ring (606). At this time, the welding machine converts electricity into heat, and a large amount of heat will enter the heating welding rod (604) through the heating connecting wire (605). At this time, after the heating welding rod (604) is heated, the heating welding rod (604) will be directly welded between the sleeve (603) and the PVC foam board production machine, thereby connecting the device and the PVC foam board production machine to complete the operation.
