The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0041] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0042] This invention provides an automatic nonwoven fabric raw material dispensing device, such as... Figures 1-4 As shown, it includes a mixing tank 2 and a stirring assembly disposed within the mixing tank 2, the stirring assembly comprising:

[0043] The external spiral rod 23, which is vertically fixed at the center of the mixing box 2, can be fixed by welding.

[0044] An inner spiral sleeve 24 is fitted onto the outer spiral rod 23 and spirally engaged with it. Both ends of the inner spiral sleeve 24 are fixed with mesh plates 19. The cross-section of the mesh plates 19 is V-shaped. A stirring rod is fixed on the inner spiral sleeve 24.

[0045] Rotate the connecting sleeve 22 connected to the inner spiral sleeve 24;

[0046] The drive mechanism installed on the mixing box 2 is used to drive the connecting sleeve 22 to reciprocate in the vertical direction;

[0047] During operation, the drive mechanism drives the connecting sleeve 22 to reciprocate in the vertical direction. The connecting sleeve 22 drives the inner spiral sleeve 24 to reciprocate up and down along the outer spiral rod 23. Due to the spiral cooperation between the two, the inner spiral sleeve 24 rotates alternately in the forward and reverse directions. The inner spiral sleeve 24 drives the screen plate 19 and the stirring rod on it to reciprocate up and down and rotate alternately in the forward and reverse directions. When the screen plate 19 rotates, the raw materials on the screen plate 19 move and scatter in all directions under centrifugal force, which can fully stir and mix the raw materials in the batching box 2, making the raw materials more fully and evenly mixed and the batching effect better.

[0048] The drive mechanism includes:

[0049] The first stepper motor 5, which is fixed to the two side walls of the mixing box 2, can be fixed by bolts, and the output shaft of the first stepper motor 5 extends into the mixing box 2.

[0050] A turntable 4 is located inside the mixing box 2 and fixed on the output shaft of the first stepper motor 5. A drive pin 32 is eccentrically fixed on the turntable 4.

[0051] A drive rod 20 is longitudinally arranged on the turntable 4 near the connecting sleeve 22. Both ends of the drive rod 20 are fixed with sliders. The sliders are slidably connected to the inner side wall of the mixing box 2. A movable groove is provided on the drive rod 20 along its length for the drive pin 32 to be inserted and moved.

[0052] The connecting rod 21, which is fixedly connected between the drive rod 20 and the connecting sleeve 22, can be fixed by welding.

[0053] Start the first stepper motor 5. The first stepper motor 5 drives the turntable 4 to rotate. The turntable 4 drives the drive pin 32 to perform circular motion. The drive pin 32 drives the drive rod 20 to move up and down reciprocally. The drive rod 20 drives the connecting sleeve 22 to move up and down reciprocally through the connecting rod 21.

[0054] Specifically, the ingredient container 2 is fixed to the base 1. Furthermore, a moving mechanism is installed inside the base 1 for easy movement. The moving mechanism includes:

[0055] A bidirectional lead screw that is horizontally rotatably mounted within base 1;

[0056] The third stepper motor 26, fixed on the base 1, is used to drive the bidirectional lead screw to rotate. The output shaft of the third stepper motor 26 can be fixedly connected to one end of the bidirectional lead screw through a coupling.

[0057] An internal threaded sleeve is threaded onto the two threaded sections of a bidirectional lead screw. The internal threaded sleeve is horizontally slidably connected to the base 1. A second connecting rod 27 is hinged to each internal threaded sleeve. Multiple coaxially arranged rollers 28 are rotatably mounted on the end of the second connecting rod 27 away from the internal threaded sleeve. A first connecting rod 25 is hinged to the shaft of the roller 28. The end of the first connecting rod 25 away from the roller 28 is hinged to the base 1. The first connecting rod 25 and the second connecting rod 27 extend to both sides of the roller 28, respectively.

[0058] The third stepper motor 26 drives the bidirectional lead screw to rotate, which in turn drives the inner threaded sleeve to move. The inner threaded sleeve drives the roller 28 to move out of the base 1 through the second connecting rod 27 and supports the ground for easy movement. When movement is not required, the third stepper motor 26 is started to reverse, so that the roller 28 moves back into the base 1 and the base 1 supports the ground.

[0059] In this embodiment, the automatic nonwoven fabric raw material dispensing device further includes a feeding component, which includes:

[0060] The mounting plate 8 is located above the mixing box 2. The mounting plate 8 is fixedly connected to the mixing box 2 by multiple support rods 7, which can be fixed by welding.

[0061] Multiple raw material boxes 9 are fixed to the mounting plate 8 at circumferential intervals and can be fixed by screws. The top of the raw material box 9 is provided with a feeding hopper and the bottom of the raw material box 9 is provided with a first discharge port 13. A valve structure is installed on the mounting plate 8 at each first discharge port 13 for opening or closing the first discharge port 13. The top of the batching box 2 is provided with a second feeding port 18, which is located at the circumferential center of the multiple raw material boxes 9.

[0062] A material transfer structure located between the mounting plate 8 and the batching box 2 is used to connect the first discharge port 13 and the second inlet port 18 of a raw material box 9 each time.

[0063] The raw materials in each raw material box 9 flow into the transfer structure through the first discharge port 13, and then flow into the batching box 2 through the second inlet port 18 for stirring and mixing.

[0064] In specific implementation, the material transfer structure includes:

[0065] A rotating material cylinder 14 is located below the mounting plate 8. The top of the rotating material cylinder 14 is provided with a first inlet that can communicate with the first outlet 13. The bottom of the rotating material cylinder 14 is provided with a second outlet. The second outlet is connected to the second inlet 18 through a guide pipe 12. The guide pipe 12 and the second inlet 18 are rotatably connected.

[0066] A mounting shaft 17 is coaxially rotatably installed inside the rotating material cylinder 14. Multiple partitions 15 are fixed circumferentially on the mounting shaft 17. Two adjacent partitions 15 and the cylinder wall of the rotating material cylinder 14 enclose a raw material receiving cavity. A fifth stepper motor is fixed at one end of the rotating material cylinder 14 to drive the mounting shaft 17 to rotate intermittently. The output shaft of the fifth stepper motor can be fixedly connected to the mounting shaft 17 through a coupling.

[0067] A second stepper motor 10 is fixed on the mounting plate 8. The output shaft axis of the second stepper motor 10 passes through multiple raw material boxes 9 and circles towards the center position. A crankshaft 11 is fixed on the output shaft of the second stepper motor 10. The crankshaft 11 is fixedly connected to the rotating drum 14.

[0068] In operation, the second stepper motor 10 drives the crankshaft 11 to rotate, which in turn drives the rotating drum 14 to rotate. The first feed inlet at the top of the rotating drum 14 transfers materials between the first discharge outlets 13 at the bottom of multiple material bins 9. When the rotating drum 14 moves to the bottom of a certain material bin 9, with the first feed inlet located directly below the first discharge outlet 13 at the bottom of that material bin 9, the fourth stepper motor 29 is activated to drive the valve plate 30 to rotate, opening the first discharge outlet 13 at the bottom of that material bin 9 and connecting it with the first feed inlet. The materials in this material bin 9 then enter a receiving cavity. After a period of time, the fourth stepper motor 29 drives the valve plate 30 to reset, opening the first discharge outlet 13 at the bottom of this material bin 9. The first discharge port 13 is closed. At the same time, the second stepper motor 10 drives the rotating drum 14 to rotate below the other raw material box 9. The fifth stepper motor drives the mounting shaft 17 to rotate. The mounting shaft 17 drives the partition 15 to rotate, so that the other receiving cavity is connected to the first feed port. The first discharge port 13 of the other raw material box 9 is opened, and the raw materials in the other raw material box 9 enter the other receiving cavity. After the raw materials in each raw material box 9 have entered their respective receiving cavities, the fifth stepper motor is started to drive the mounting shaft 17 to rotate continuously. The mounting shaft 17 drives the partition 15 to rotate, so that the raw materials in each receiving cavity flow out from the second discharge port, flow into the second feed port 18 through the guide pipe 12, and fall into the batching box 2.

[0069] Furthermore, each of the aforementioned accommodating cavities is provided with an airbag 16, and an inflation / deflation pipe 31 is connected to the airbag 16. The inflation / deflation pipe 31 extends into and out of the mounting shaft 17. A valve is installed on the inflation / deflation pipe 31. It can be connected to different inflation / deflation pipes 31 by means of an air pump or air inflator to inflate different airbags 16, or the valve on the inflation / deflation pipe 31 can be opened to deflate different airbags 16, thereby adjusting the volume of different accommodating cavities and thus adjusting the amount of different raw materials added.

[0070] Furthermore, the valve structure includes:

[0071] A valve plate 30 is located on the lower side of the first discharge port 13;

[0072] The fourth stepper motor 29, fixed on the mounting plate 8, is used to drive the valve plate 30 to rotate. The output shaft of the fourth stepper motor 29 can be welded and fixed to the valve plate 30. The valve plate 30 is driven to rotate by the fourth stepper motor 29.

[0073] Preferably, a plurality of first protrusions 6 are fixed at intervals on the side wall of the turntable 4, and a plurality of arc-shaped plates 3 are fixed on the inner side wall of the mixing box 2 located outside the turntable 4, which can be fixed by welding. A second protrusion that can abut and cooperate with the first protrusions 6 is fixed on the arc-shaped plate 3.

[0074] It should be explained that when the first stepper motor 5 drives the turntable 4 to rotate, the turntable 4 drives the first protrusion 6 to rotate. When the first protrusion 6 rotates, it intermittently contacts the second protrusion, causing the mixing box 2 to vibrate. On the one hand, this is beneficial for mixing the raw materials in the mixing box 2. On the other hand, the raw material box 9 vibrates, which is beneficial for the smooth discharge of the raw material box 9 and avoids blockage of the first discharge port 13.

[0075] In summary, this invention provides an automatic nonwoven fabric raw material dispensing device, the working principle of which is as follows:

[0076] Different raw materials are added to different raw material bins 9. The second stepper motor 10 drives the crankshaft 11 to rotate, which in turn drives the rotating drum 14 to rotate. The first inlet at the top of the rotating drum 14 transfers materials between the first outlets 13 at the bottom of the multiple raw material bins 9. When the rotating drum 14 moves to the bottom of a certain raw material bin 9, with the first inlet located directly below the first outlet 13 at the bottom of that raw material bin 9, the fourth stepper motor 29 is activated, driving the valve plate 30 to rotate. This opens the first outlet 13 at the bottom of that raw material bin 9 and connects it to the first inlet, allowing the raw materials in that raw material bin 9 to enter a receiving cavity. After a period of time, the fourth stepper motor 29 drives the valve plate 30 to reset, closing the first outlet 13 at the bottom of that raw material bin 9. Simultaneously, the second stepper motor 10 drives the rotating drum 14 to rotate to the bottom of another raw material bin 9. The fifth stepper motor drives the mounting shaft 17 to rotate, which in turn drives the partition plate 15 to rotate, connecting another receiving cavity to the first inlet, allowing the first outlet of the other raw material bin 9 to be discharged. When the feed inlet 13 is opened, the raw materials in another raw material box 9 enter another receiving cavity. After the raw materials in each raw material box 9 have entered their respective receiving cavities, the fifth stepper motor is started to drive the mounting shaft 17 to rotate continuously. The mounting shaft 17 drives the partition plate 15 to rotate, so that the raw materials in each receiving cavity flow out from the second discharge port, flow into the second feed inlet 18 through the guide pipe 12, and fall into the batching box 2. At the same time, the first stepper motor 5 drives the turntable 4 to rotate. The turntable 4 drives the drive pin 32 to perform circumferential motion. The drive pin 32 drives the drive rod 20 to move up and down reciprocally. The drive rod 20 drives the connecting sleeve 22 to move up and down reciprocally through the connecting rod 21. The connecting sleeve 22 drives the inner spiral sleeve 24 to move up and down reciprocally along the outer spiral rod 23. Due to the spiral cooperation between the two, the inner spiral sleeve 24 rotates alternately in both directions. The inner spiral sleeve 24 drives the mesh plate 19 and the stirring rod on it to move up and down reciprocally and rotate alternately in both directions, which can fully stir and mix the raw materials in the batching box 2, making the raw materials more fully and evenly mixed, and the batching effect better.
