Technical Field

[0001] The utility model belongs to the field of shredding equipment, and particularly relates to a feeding and crushing device for a crusher for compressed waste paper shells. Background Art

[0002] Waste paper shells generally refer to various cardboard papers, cartons, trimmed papers, wrapping papers, etc. that are discarded after use in production and life, and a large amount of waste paper shells are generated every day.

[0003] With the increasing application of the spraying greening ecological restoration technology, the demand for spraying substrates is increasing. In order to save energy and realize the resource utilization of waste, recycling waste paper shells and adding them to the spraying substrate after crushing can maximize the resource value of waste paper shells and is of great significance to environmental protection. After being recycled, waste paper shells are generally compressed into square blocks for easy storage and transportation.

[0004] Before crushing, the compressed waste paper shells need to be scattered or disassembled. At present, the scattering or disassembling work is mainly completed manually. Since some larger or longer waste paper shells will form clusters during compression, it takes a long time to complete the scattering or disassembling, resulting in low efficiency. In addition, when manually scattering or disassembling, a large amount of physical strength is consumed and floating dust is generated, resulting in a poor working environment. At the same time, due to the high hardness of the compressed waste paper shells, the equipment is often stuck. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the present utility model will be specifically described through exemplary embodiments. However, it should be understood that without further description, the elements, structures, and features in one embodiment can also be beneficially combined into other embodiments.

[0025] A feeding and crushing device for a compressed waste paper shell crusher, see Figures 1 to 4 , including a bracket 1 and a storage bin 2 connected to the top end of the bracket 1 for storing compressed waste paper shells;

[0026] The side of the storage bin 2 has a feed inlet 21, and a switch door can be set on the feed inlet 21. After feeding, the switch door can be closed to prevent dust from leaking. On the storage bin 2, a feeding port 22 is arranged on the lower side of the opposite side of the feed inlet 21. The bottom of the storage bin 2 has a blanking port 23. Observation ports 25 are respectively arranged on the storage bin 2 on both sides of the feeding port 22. Reinforcing ribs 24 are arranged horizontally and vertically on the outer side surface of the storage bin 2;

[0027] Below the storage bin 2, a conveyor line 3 is arranged on the bracket 1. A number of pushing blocks 31 are arranged on the conveying surface of the conveyor line 3. The conveyor line 3 corresponds to the blanking port 23 and the feeding port 22. The conveyor line 3 includes rotating shafts 32 arranged at both ends of the bracket 1. The rotating shafts 32 can rotate and are driven by a first transmission chain 33 and a first motor 34. Conveyor sprockets are arranged on the rotating shafts 32. The rotating shafts 32 are connected by a chain plate 35 connected to the conveyor sprockets. The pushing blocks 31 are arranged on the chain plate 35. Due to the pushing blocks 31 arranged on the conveyor line 3, during the conveying process, the compressed waste paper shells fall on the conveyor line 3 under the action of gravity. Under the pushing of the pushing blocks 31, the bottom of the compressed waste paper shells can be quickly stratified and disassembled, improving the efficiency. The decomposed shredded paper shells are conveyed forward and transferred out;

[0028] In front of the conveyor line 3, a frame 4 is arranged. A rotatable feeding roller 5 is arranged on the frame 4. The feeding roller 5 is located at the position of the feeding port 22 above the conveyor line 3. The rotation direction of the feeding roller 5 is opposite to that of the conveyor line 3. The feeding roller 5 has a number of arranged feeding teeth 51. In front of the conveyor line 3, a frame 4 is arranged. The feeding roller 5 is rotatably connected to the frame 4, and the feeding roller 5 is driven by a second transmission chain 52 and a second motor 53. The feeding teeth 51 on the feeding roller 5 are in the shape of strip-shaped saw teeth, which are parallel to the axis of the feeding roller 5, surround the circumference of the feeding roller 5, and are arranged along the length direction of the feeding roller 5. Since the rotation direction of the feeding roller 5 is opposite to the conveying direction of the conveyor line 3, the feeding roller 5 rotates in the opposite direction, and the feeding teeth 51 can tightly bite the waste paper shells and feed them forward;

[0029] In order to prevent the pushing blocks 31 from adhering to shredded paper scraps after stratifying and disassembling the compressed waste paper shells, in front of the conveyor line 3, a conveyor stripping plate 36 is connected to the frame 4. The conveyor stripping plate 36 is provided with conveyor stripping teeth 37 corresponding to the pushing blocks 31. When the pushing blocks 31 rotate to the front end of the conveyor line 3, the pushing blocks 31 are embedded into the tooth roots of the conveyor stripping teeth 37 to remove the shredded paper scraps adhered to the pushing blocks 31;

[0030] In front of the conveyor line 3, a fixed knife blade plate 7 is connected to the frame 4. There are multiple fixed knives 71 on the fixed knife blade plate 7. The fixed knives 71 are vertically arranged groove-shaped structures. In front of the fixed knives 71, a knife roller 8 is rotatably connected to the frame 4. There are multiple crushing knives 81 arranged on the knife roller 8. The multiple crushing knives 81 are arranged in a spiral shape on the knife roller 8. When the knife roller 8 rotates, the crushing knives 81 cooperate with the fixed knives 71 to crush the paper shells.

[0031] In order to enable the waste paper shells hooked on the feeding teeth 51 to fall off smoothly, above the fixed knife blade plate 7, a feeding and discharging plate 6 is arranged between the feeding roller 5 and the knife roller 8. The front end of the feeding and discharging plate 6 corresponds to the fixed knife blade plate 7. There are multiple feeding and discharging teeth 61 arranged on the feeding and discharging plate 6. When the feeding roller 5 rotates, the teeth 61 of the feeding and discharging teeth 61 are inserted into the roots of the feeding teeth 51, and there is a gap of 3 - 5 mm between the two. The feeding and discharging teeth 61 can enable the waste paper shells hooked on the feeding teeth 51 after feeding to fall off smoothly, which is convenient, fast and efficient.

[0032] In order to enable the waste paper shells hooked on the crushing knives 81 to fall off smoothly, a crushing and discharging plate 9 is arranged in front of the knife roller 8. There are multiple crushing and discharging teeth 91 arranged on the crushing and discharging plate 9. When the knife roller 8 rotates, the crushing knives 81 are sequentially inserted into the crushing and discharging teeth 91, which can enable the waste paper shells hooked on the crushing knives 81 after crushing to fall off smoothly, which is convenient, fast and efficient.

[0033] In order to discharge the fallen waste paper shells, a guide plate is obliquely arranged below the front end of the conveyor line 3. The guide plate is located below the feeding and discharging plate 6 and the fixed knife blade plate 7.

[0034] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
