The side is located inside the inclined groove. A crossbar is vertically slidably connected inside the box body. A bending groove is provided inside the box body. A second connecting rod is rotatably connected to the outside of the crossbar. A connecting shaft is rotatably connected to the top of the second connecting rod. Push plates are fixedly provided on both sides of the connecting shaft. A second insert is fixedly provided on the rear surface of the connecting shaft. The rear end of the second insert is located inside the bending groove. A third cutter is rotatably connected inside the box body.

A second vertical shaft is fixedly provided at the bottom of the crossbar. The bottom of the second vertical shaft is located inside the groove.

[0012] Preferably, the first worm gear meshes with the first worm, the stop block passes through the first opening, the protrusion passes through the second opening, and the first insert extends into the interior of the oblique groove.

[0013] Preferably, a placement plate is fixedly provided on the rear surface of the box, and the placement plate is located at the bottom of the second cutter.

[0014] Preferably, the top of the box is provided with a feed inlet, the bottom of the box is provided with a discharge outlet, and the third cutter is located at the bottom of the feed inlet.

[0015] Preferably, there are two sector-shaped toothed rods and two push rods, the rack meshes with the two sector-shaped toothed rods, and the sector-shaped toothed rods are rotatably connected to the push rods.

[0016] The paper cutter for paper production proposed in this invention has the following advantages:

[0017] 1. Using the paper-cutting mechanism, the paper to be cut is placed vertically on top of the first placement rack and horizontally on top of the placement plate. The wood for making paper is manually held and placed at the bottom of the saw teeth. The curved paper is placed vertically on top of the second placement rack. The first motor is started to drive the first worm gear to rotate, which in turn drives the first worm wheel to rotate. When the first worm wheel rotates, the stop block slides in the first opening and drives the swing arm to rotate back and forth. When the swing arm rotates back and forth, the protrusion moves in the second opening and drives the vertical plate to slide back and forth horizontally. When the vertical plate slides back and forth horizontally, it drives the first cutter to cut the paper and also drives the saw teeth to cut the wood. At the same time, when the first worm wheel rotates, since the rear end of the first insert is located inside the inclined groove, the rotation of the first worm wheel will drive the vertical rod to rise and fall, which in turn drives the vertical rod and the second cutter to rise and fall. This is beneficial for cutting another set of paper by raising and lowering the second cutter. At the same time, when the second cutter rises and falls, it will drive the first connecting rod to rotate. The rotation of the first connecting rod will cause the pressure plate to slide back and forth horizontally on top of the second placement rack, which is beneficial for straightening the curved paper.

[0018] 2. Through the set processing mechanism, the second motor is started to drive the second worm gear to rotate, which in turn drives the second worm wheel and the inclined column to rotate. Since the bottom of the second vertical shaft is located inside the groove, when the inclined column rotates, the inclined design of the groove can drive the second vertical shaft to rise and fall, which in turn drives the horizontal bar to rise and fall. When the horizontal bar rises and falls, it drives the first vertical shaft to rise and fall. The rise and fall of the first vertical shaft helps to drive the third cutter to reciprocate and rotate, crushing the cut waste paper into long strips and then passing them through the feed inlet. When passing through the feed inlet, the reciprocating rotation of the third cutter can shred the waste paper. Then the waste paper enters the bottom of the box, and clean water is injected into the inside of the box through the feed inlet. Since the second insert is located inside the bending groove, when When the crossbar rises and falls, the second insert moves along the trajectory of the bending groove, which in turn drives the second connecting rod to rotate. When the second connecting rod rotates, it drives the connecting shaft and push plate to agitate the water, which helps to quickly mix the clean water and waste paper. At the same time, since one side of the extension rod is located inside the inclined groove, when the inclined column rotates, it can drive the extension rod to rise and fall. This movement of the extension rod drives the rack to rise and fall, which in turn drives the fan-shaped rack to rotate. The rotation of the fan-shaped rack drives the top rod to rotate and squeeze the elastic plate to deform it. During the process of squeezing the elastic plate and causing deformation, the water is further agitated, which helps to fully mix the waste paper scraps and water to form coarse pulp for secondary use. The coarse pulp is discharged into a designated container through the discharge port. Attached Figure Description

[0028] Example 1

[0029] Key reference Figure 2 , 3 6. A paper cutter for paper production, comprising:

[0030] Box 1, used for making pulp;

[0031] The paper cutting mechanism is located on the rear surface of the housing 1;

[0032] The processing mechanism is located inside housing 1;

[0033] The paper cutting mechanism includes a first motor 2 fixedly mounted on the rear surface of the housing 1, a first worm gear 3 fixedly mounted on the output end of the first motor 2, a first worm wheel 4 rotatably connected to the rear surface of the housing 1, a first placement frame 5 and a second placement frame 6 fixedly mounted on the rear surface of the housing 1, a vertical plate 7 horizontally slidably connected to the rear surface of the housing 1, a saw tooth 8 fixedly mounted on the bottom of the vertical plate 7, a first cutter 9 fixedly mounted on one side of the vertical plate 7, a stop block 11 fixedly mounted on the front surface of the first worm wheel 4, a beveled groove 12 mounted on the rear surface of the first worm wheel 4, a swing rod 13 rotatably connected inside the housing 1, a first opening 14 and a second opening 15 respectively mounted on the top and bottom of the swing rod 13, a protrusion 44 fixedly mounted on the other side of the vertical plate 7, the first worm wheel 4 meshing with the first worm gear 3, the stop block 11 penetrating through the first opening 14, the protrusion 44 penetrating through the second opening 15, and a first insert block 19 extending into the interior of the beveled groove 12.

[0034] Specifically, the paper to be cut or trimmed is placed vertically on top of the first placement rack 5 and horizontally on top of the placement plate 10. The wood for making the paper is manually held and placed at the bottom of the saw teeth 8. The bent paper is placed vertically on top of the second placement rack 6. The first motor 2 is started to drive the first worm gear 3 to rotate, which in turn drives the first worm wheel 4 to rotate. When the first worm wheel 4 rotates, the stop block 11 slides in the first opening 14 and drives the swing arm 13 to rotate back and forth. When the swing arm 13 rotates back and forth, the protrusion 44 moves in the second opening 15 and drives the vertical plate 7 to slide back and forth horizontally. When the vertical plate 7 slides back and forth horizontally, it drives the first cutter 9 to cut the paper and can also drive the saw teeth 8 to move to saw the wood.

[0035] The rear surface of the box 1 is vertically slidably connected to a second cutter 16, the top of the second cutter 16 is fixedly connected to a vertical rod 17, a vertical rod 18 is fixedly installed on one side of the vertical rod 17, a first insert block 19 is fixedly installed at the bottom of the vertical rod 18, the top of the second placement rack 6 is horizontally slidably connected to a pressure plate 20, the outside of the second cutter 16 is rotatably connected to a first connecting rod 21, and one end of the first connecting rod 21 is rotatably connected to the pressure plate 20. The rear surface of the box 1 is fixedly provided with a placement plate 10, which is located at the bottom of the second cutter 16.

[0036] Specifically, when the first worm gear 4 rotates, since the rear end of the first insert block 19 is located inside the inclined groove 12, the rotation of the first worm gear 4 will drive the vertical rod 18 to rise and fall, which in turn will drive the vertical rod 17 and the second cutter 16 to rise and fall. The second cutter 16 will cut another set of paper by rising and falling. At the same time, the second cutter 16 will drive the first connecting rod 21 to rotate. The rotation of the first connecting rod 21 will cause the pressure plate 20 to slide horizontally back and forth on the top of the second placement frame 6 to straighten the bent paper.

[0037] Example 2

[0038] Key reference Figure 1 , 4 5. The processing mechanism includes a support pad 22 fixedly installed inside the housing 1. A second worm gear 23 is rotatably connected to the top of the support pad 22. A second motor 24 is fixedly installed outside the housing 1. The output end of the second motor 24 is located inside the housing 1 and is fixedly connected to a second worm 25. The second worm gear 23 meshes with the second worm 25. An inclined column 26 is fixedly installed on the top of the second worm gear 23. An inclined groove 27 is provided on the outside of the inclined column 26 and a groove 28 is provided on the top. A fan-shaped toothed rod 29 and a top rod 30 are rotatably connected inside the housing 1 and a rack 31 is vertically slidably connected. Two elastic plates 32 are fixedly installed at the bottom of the housing 1. An extension rod 33 is fixedly installed on the top of the rack 31. There are two fan-shaped toothed rods 29 and two top rods 30. The rack 31 meshes with the two fan-shaped toothed rods 29. The fan-shaped toothed rods 29 and the top rod 30 are rotatably connected.

[0039] Specifically, the second motor 24 is started to drive the second worm gear 25 to rotate, which in turn drives the second worm wheel 23 and the inclined column 26 to rotate. Since one side of the extension rod 33 is located inside the inclined groove 27, when the inclined column 26 rotates, it can drive the extension rod 33 to rise and fall. The rise and fall of the extension rod 33 drives the rack 31 to rise and fall, which in turn drives the sector rack 29 to rotate. The rotation of the sector rack 29 drives the top rod 30 to rotate and squeeze the elastic plate 32 to deform it. During the process of squeezing the elastic plate 32 and causing deformation, the water will be further agitated, so that the waste paper scraps and water are fully mixed to form pulp coarse material for secondary use. The pulp coarse material is discharged into the designated container through the discharge port.

[0040] One side of the extension rod 33 is located inside the inclined groove 27. A crossbar 34 is vertically slidably connected inside the box body 1. A bending groove 35 is provided inside the box body 1. A second connecting rod 36 is rotatably connected to the outside of the crossbar 34. A connecting shaft 37 is rotatably connected to the top of the second connecting rod 36. Push plates 38 are fixedly provided on both sides of the connecting shaft 37. A second insert block 39 is fixedly provided on the rear surface of the connecting shaft 37. The rear end of the second insert block 39 is located inside the bending groove 35. A third cutter 40 is rotatably connected inside the box body 1. A first vertical shaft 41 is fixedly provided at the top of the crossbar 34. The top of the first vertical shaft 41 is rotatably connected to the third cutter 40. A second vertical shaft 42 is fixedly provided at the bottom of the crossbar 34. The bottom of the second vertical shaft 42 is located inside the groove 28. A feed inlet 43 is provided at the top of the box body 1. A discharge outlet is provided at the bottom of the box body 1. The third cutter 40 is located at the bottom of the feed inlet 43.

[0041] Specifically, since the bottom of the second vertical shaft 42 is located inside the groove 28, when the inclined column 26 rotates, the inclined design of the groove 28 can drive the second vertical shaft 42 to rise and fall, which in turn drives the horizontal bar 34 to rise and fall. When the horizontal bar 34 rises and falls, it drives the first vertical shaft 41 to rise and fall. The rise and fall of the first vertical shaft 41 drives the third cutter 40 to rotate back and forth, which rolls the cut waste paper into long strips and then passes through the feed inlet 43. When passing through the feed inlet 43, the waste paper can be shredded by the reciprocating rotation of the third cutter 40. Then the waste paper enters the bottom of the box 1. Clean water is injected into the inside of the box 1 through the feed inlet 43. Since the second insert 39 is located inside the bending groove 35, when the horizontal bar 34 rises and falls, the second insert 39 moves along the trajectory of the bending groove 35, which will drive the second connecting rod 36 to rotate. When the second connecting rod 36 rotates, it can drive the connecting shaft 37 and the push plate 38 to stir the water, so that the clean water and waste paper can be quickly mixed.

[0042] Working principle: Place the paper to be cut vertically on top of the first placement rack 5 and horizontally on top of the placement plate 10. Manually hold the wood for making paper and place it at the bottom of the saw teeth 8. Place the curved paper vertically on top of the second placement rack 6. Start the first motor 2 to drive the first worm gear 3 to rotate, which in turn drives the first worm wheel 4 to rotate. When the first worm wheel 4 rotates, the stop block 11 slides in the first opening 14 and drives the swing arm 13 to rotate back and forth. When the swing arm 13 rotates back and forth, the protrusion 44 moves in the second opening 15 and drives the vertical plate 7 to slide back and forth horizontally. When the vertical plate 7 slides back and forth horizontally, it drives the first cutter 9 to cut the paper and also drives the saw teeth 8 to move and cut the wood. As the first worm gear 4 rotates, the rear end of the first insert block 19 is located inside the inclined groove 12. Therefore, when the first worm gear 4 rotates, it will drive the vertical rod 18 to rise and fall, which in turn will drive the vertical rod 17 and the second cutter 16 to rise and fall. The second cutter 16 will cut another set of paper by rising and falling. At the same time, the second cutter 16 will drive the first connecting rod 21 to rotate. The rotation of the first connecting rod 21 will cause the pressure plate 20 to slide horizontally back and forth on the top of the second placement frame 6 to straighten the bent paper. The second motor 24 will start to drive the second worm gear 25 to rotate, which will in turn drive the second worm gear 23 and the inclined column 26 to rotate. Since the bottom of the second vertical shaft 42 is located inside the groove 28, when the inclined column 25 rotates, the second worm gear 26 will rotate. When the 6th column rotates, the inclined design of the groove 28 drives the second vertical shaft 42 to rise and fall, which in turn drives the horizontal bar 34 to rise and fall. When the horizontal bar 34 rises and falls, it drives the first vertical shaft 41 to rise and fall. The rise and fall of the first vertical shaft 41 drives the third cutter 40 to rotate back and forth, rolling the cut waste paper into long strips and then passing them through the feed inlet 43. When passing through the feed inlet 43, the reciprocating rotation of the third cutter 40 can shred the waste paper, and then the waste paper enters the bottom of the box 1. Clean water is injected into the interior of the box 1 through the feed inlet 43. Since the second insert 39 is located inside the bending groove 35, when the horizontal bar 34 rises and falls, the second insert 39 moves along the trajectory of the bending groove 35, and then... The second connecting rod 36 rotates, which drives the connecting shaft 37 and the push plate 38 to agitate the water, allowing the clean water and waste paper to mix quickly. At the same time, since one side of the extension rod 33 is located inside the inclined groove 27, the rotation of the inclined column 26 can drive the extension rod 33 to rise and fall. The rise and fall of the extension rod 33 drives the rack 31 to rise and fall, which in turn drives the fan-shaped rack 29 to rotate. The rotation of the fan-shaped rack 29 drives the top rod 30 to rotate and squeeze the elastic plate 32 to deform it. During the process of squeezing the elastic plate 32 and causing deformation, the water is further agitated, allowing the waste paper scraps and water to fully mix to form pulp coarse material for secondary use. The pulp coarse material is discharged into a designated container through the discharge port.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
