Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically an automatic feeding device for the production of nanocellulose. Background Technology

[0002] With the continuous development of nanotechnology, nanocellulose, as a novel bio-based material, has been widely used in many fields due to its excellent mechanical properties, biodegradability, good dispersibility, and renewability, especially in paper manufacturing, coatings, composite materials, and drug delivery systems. The production of nanocellulose typically involves extracting cellulose slurry using wet or chemical methods, followed by further processing to obtain the final nanocellulose product.

[0003] When nanocellulose slurry is extracted by wet or solution methods, the cellulose fibers may absorb water and swell, resulting in a high viscosity of the slurry. Nanocellulose slurry is prone to clumping during the conveying and feeding process, especially when the conveying is insufficient. The cross-linking and accumulation of cellulose fibers may lead to clumping, which in turn affects the subsequent processing of nanocellulose. Utility Model Content

Detailed Implementation

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Please see Figure 1-Figure 4 This utility model provides a technical solution: an automatic feeding device for nanocellulose production, comprising two guide rails 1, a U-shaped connecting rod 10, a base plate 12, and a feeding hopper 11. The U-shaped connecting rod 10 is installed on the top of the feeding hopper 11. Vertical rods 3 are installed at both ends of the guide rails 1, and a horizontal rod 4 is fixedly installed between the two vertical rods 3. Multiple magnetic plates 5 are provided on the side wall of one of the horizontal rods 4, with adjacent magnetic plates 5 having opposite magnetic poles. Guide seats 2 are slidably installed at the bottom of both guide rails 1, and a connecting plate 6 is fixedly installed at the bottom of both guide seats 2. A mounting base 7 is fixedly installed at the bottom. A multi-stage telescopic rod 8 is installed inside the mounting base 7. The output end of the multi-stage telescopic rod 8 is fixedly connected to the top of the U-shaped connecting rod 10. A connecting rod 13 is fixedly installed inside the U-shaped connecting rod 10. A connecting ring 14 is fixedly installed on the outer wall of the connecting rod 13. A connecting rope 15 is fixedly installed at the bottom of the connecting ring 14. A moving block 16 is fixedly installed at the bottom of the connecting rope 15. The moving block 16 is located inside the discharge bucket 11. A limit component is provided between the two crossbars 4. The discharge bucket 11 is connected to the base plate 12 through a snap-fit ​​component.

[0019] The working principle of the above technical solution is as follows: Through the action of the multi-stage telescopic rod 8, the structure at the bottom of the U-shaped connecting rod 10 is moved to the bottom. Then, nanocellulose is loaded into the discharge bin 11. With the help of the snap-fit ​​assembly and the base plate 12, the nanocellulose is loaded into the inner cavity of the discharge bin 11. Then, the multi-stage telescopic rod 8 is used to lift the structure at the bottom of the U-shaped connecting rod 10 to a suitable height. Then, through the controller, the guide seat 2 moves on the guide rail 1, driving the discharge bin 11 to move. During the movement of the discharge bin 11 between the two crossbars 4, since the moving block 16 is made of ferromagnetic material, and since the magnetic poles of the two adjacent magnetic plates 5 are opposite, when the moving block 16 encounters the magnetically attracted magnetic plate 5, it approaches... The magnetic plate 5, at this time, the connecting rope 15 exerts a pulling force on the moving block 16, crushing the clumps of nanocellulose on the side wall, and then moves between the two magnetic plates 5. The moving block 16 has no magnetic attraction, so the moving block 16 swings under its own weight and the pulling force of the connecting rope 15, crushing the clumps of nanocellulose in the feeding bucket 11. When it encounters the magnetic plate 5 with magnetic repulsion, it is pushed to the other side of the feeding bucket 11, crushing the clumps of nanocellulose on the inner wall of the other side, and then moves between the two magnetic plates 5. The moving block 16 swings under its own weight and the pulling force of the connecting rope 15. When it moves to the limiting component, it cooperates with the snap-fit ​​component to put the nanocellulose in the feeding bucket 11 into other equipment for processing.

[0020] In another implementation scheme, such as Figures 1-3 As shown, the snap-fit ​​assembly includes a triangular plate 9 installed on the side wall of the base plate 12. A snap-fit ​​block 20 is fixedly installed on the top of the triangular plate 9. A snap-fit ​​groove 21 is opened on the outer wall of the feeding barrel 11. The snap-fit ​​block 20 is snapped into the snap-fit ​​groove 21. Two snap-fit ​​grooves 19 are opened inside the feeding barrel 11. An inverted triangular plate 17 is fixedly installed on one side of the top of the base plate 12. Snap-fit ​​blocks 18 are fixedly installed at both ends of the top of the inverted triangular plate 17. Snap-fit ​​blocks 18 are snapped into the corresponding snap-fit ​​grooves 19.

[0021] By setting up the snap-fit ​​component, the base plate 12 is removed from the bottom of the feeding hopper 11, and the crushed nanocellulose in the feeding hopper 11 is fed into other equipment for processing, realizing automatic feeding to equipment with a higher height.

[0022] In another implementation scheme, such as Figure 1 and Figure 4 As shown, the limiting component includes a horizontal plate 22 installed between two horizontal bars 4. A rectangular groove 25 is provided on the top of the horizontal plate 22. Two arc-shaped baffles 23 are fixedly installed on both sides inside the rectangular groove 25. A through groove 24 is provided at the bottom of the horizontal plate 22. The through groove 24 is connected to the rectangular groove 25. The diameter of the through groove 24 is larger than the diameter of the bottom plate 12.

[0023] By setting the limiting component, there is a certain obstruction to the snap-fit ​​component, causing the bottom plate 12 to be moved away from the bottom of the feeding barrel 11, so that the crushed nanocellulose in the feeding barrel 11 can be put into other equipment for processing.

[0024] Working principle: The multi-stage telescopic rod 8 moves the bottom structure of the U-shaped connecting rod 10 to the bottom, then nanocellulose is loaded into the discharge bin 11. With the help of the snap-fit ​​assembly and the base plate 12, the nanocellulose is loaded into the inner cavity of the discharge bin 11. Then, the multi-stage telescopic rod 8 lifts the bottom structure of the U-shaped connecting rod 10 to a suitable height. The controller then moves the guide seat 2 on the guide rail 1, causing the discharge bin 11 to move. During the movement of the discharge bin 11 between the two crossbars 4, because the moving block 16 is made of ferromagnetic material, and because the two adjacent... Since the magnetic poles of the magnetic plates 5 are opposite, when the moving block 16 encounters the magnetically attracted magnetic plate 5, it approaches the magnetic plate 5. At this time, the connecting rope 15 exerts a pulling force on the moving block 16, crushing the agglomerated nanocellulose on the side wall. Then, it moves between the two magnetic plates 5. When the moving block 16 is no longer magnetically attracted, it swings under its own weight and the pulling force of the connecting rope 15, crushing the agglomerated nanocellulose in the discharge bucket 11. When it encounters the magnetically repelled magnetic plate 5, it is pushed to the other side of the discharge bucket 11, crushing the agglomerated nanocellulose on the inner wall of the other side, and then moves between the two magnetic plates 5 again. Between these points, the moving block 16 swings under its own weight and the tension of the connecting rope 15. When the discharge bucket 11 moves onto the horizontal plate 22 and the bottom plate 12 moves within the rectangular groove 25, it encounters two arc-shaped baffles 23. The arc-shaped baffles 23 obstruct the movement of the bottom plate 12, causing the second locking block 20 on the triangular plate 9 to move out of the second locking slot 21. At the same time, the multi-stage telescopic rod 8 on the left guide rail 1 of the inverted triangular plate 17 moves out of the first locking slot 19 on the left side of the discharge bucket 11, thus moving the bottom plate 12 away from the bottom of the discharge bucket 11 until the first locking block 18 on the right side of the inverted triangular plate 17 is engaged with the right side of the discharge bucket 11. The material is fed into the slot 19 inside the feeding barrel 11 until the bottom plate 12 is removed from the bottom of the feeding barrel 11. When the feeding barrel 11 moves to the top of the through groove 24, the crushed nanocellulose in the feeding barrel 11 is fed into other equipment for processing. After feeding is completed, when the feeding barrel 11 is reset, since the right side block 18 is engaged with the slot 19, the entire feeding barrel 11 and the bottom plate 12 can be reset. Under the action of the multi-stage telescopic rod 8, the structure on the feeding barrel 11 is moved down. The bottom plate 12 is reset using external equipment, and then the material is fed into the guide rail 1. The above steps are repeated for feeding.
