Description

Technical Field

[0001] The present invention relates to the technical field of plastic processing and conveying, and particularly relates to an integrated device for processing and conveying plastic particles and a method for using the same. Background Art

[0002] Plastic is a material made of high molecular polymers, which has the characteristics of being light, durable, and highly plastic. They are widely used in daily life and industrial fields, such as packaging, containers, electronic products, and building materials. There are many types of plastics, including polyethylene, polypropylene, polyvinyl chloride, etc. Each plastic has its unique properties and uses. Although plastics bring convenience to human life, they also cause environmental problems due to their non-degradability. Therefore, the sustainable use and recycling of plastics have attracted more and more attention.

[0003] Plastic recycling refers to using certain recycling processes to recycle waste plastics and reuse them to achieve the purpose of turning waste into treasure. The recycling and reuse of waste plastics have been widely adopted by modern chemical enterprises. Waste plastics need to go through processes such as sorting, drying, crushing, modification, and granulation to make various transparent and opaque plastic particles, and then be classified according to their appearance, and finally become recycled materials that can be reused again. In the process of plastic recycling, crushing equipment is needed to crush waste plastic parts.

[0004] After the existing crushing equipment crushes plastic parts into small plastic particles, it is still necessary to use screening equipment to separate the small plastic particles from powder and dust, and then use conveying equipment to convey the small plastic particles to the next processing equipment. This requires multiple pieces of equipment to achieve crushing, screening, and conveying. Multiple pieces of equipment will occupy a large area, and it is also necessary to transfer materials between multiple equipment, which is rather inconvenient and will also result in higher processing costs. For this reason, we have proposed an integrated device for processing and conveying plastic particles and a method for using the same to solve the above problems. Summary of the Invention

Specific embodiments

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Referring to Figures 1 - 16 , a plastic particle preparation and processing and conveying integrated device, including a bottom plate 1, a fragmentation assembly is provided on the upper side of the bottom plate 1, the fragmentation assembly is used for crushing plastic parts, the fragmentation assembly includes a rough breaking assembly and a fine breaking assembly, the rough breaking assembly includes a feed pipe 2 and a gantry 6. During use, when it is necessary to fragment plastic parts, the plastic parts to be fragmented need to be placed into the feed pipe 2. A plurality of tool holders 3 are provided inside the feed pipe 2, a fragmentation knife 4 is fixedly provided inside the tool holder 3, the fragmentation knife 4 is an inclined structure, a plurality of tool holes are provided on the lower side of the feed pipe 2, two connecting rods 5 are fixedly provided on the upper side of the tool holder 3, a plurality of connecting holes are provided on the upper side of the feed pipe 2, the connecting rod 5 slides inside the connecting hole, the feed pipe 2 slides inside the gantry 6, and the upper end of the connecting rod 5 is fixed to the lower side of the top of the gantry 6. After the plastic parts to be fragmented enter the feed pipe 2, it is necessary to make the fragmentation knife 4 reciprocate to cut the plastic parts, so as to be able to roughly break the plastic parts.

[0045] As Figure 3 , Figure 4 , Figures 7 - 9As shown, an inlet component is provided inside the rough crushing component. The inlet component includes two driving shafts 22 and a number of driving conveyor belts 23. Two baffle plates 32 are fixedly provided inside the inlet pipe 2. Two mounting seats 24 are rotatably provided on the outer periphery of the driving shaft 22, and the mounting seats 24 are fixed on the outer wall of the inlet pipe 2. Two driving wheels 25 are in contact transmission on the inner side of the driving conveyor belt 23, and the driving wheels 25 are fixed on the outer periphery of the driving shaft 22. A number of accommodation holes are provided on the lower side of the inlet pipe 2, and the driving conveyor belt 23 is located inside the accommodation holes. A pressing component is provided above the driving conveyor belt 23, and the crushing knife 4 is located between two adjacent pressing components. The pressing component includes a fixed square pipe 26, the upper end of the fixed square pipe 26 is fixed on the lower side of the top of the inlet pipe 2, a T-shaped frame 27 is slidably provided inside the fixed square pipe 26, a spring 28 is fixedly provided between the upper side of the T-shaped frame 27 and the lower side of the top of the inlet pipe 2, driven conveyor belts 29 are provided on the two sides of the T-shaped frame 27 away from each other, two driven wheels 30 are rotatably provided on the two sides of the T-shaped frame 27 away from each other, and the driven wheels 30 are in contact transmission connection with the inner wall of the driven conveyor belt 29. During the crushing of the plastic part, one driving shaft 22 will rotate, and the rotation of the driving shaft 22 will drive the driving wheels 25 and the driving conveyor belt 23 to rotate. After the plastic part to be crushed is placed into the inlet pipe 2, the plastic part entering the inlet pipe 2 will automatically approach the driving conveyor belt 23 along the baffle plate 32. When the plastic part contacts the driving conveyor belt 23, the driving conveyor belt 23 will drive the plastic part to move, and then the plastic part will contact the driven conveyor belt 29. At this time, the plastic part will be clamped between the driving conveyor belt 23 and the driven conveyor belt 29. Because the spring 28 will provide a downward pressure for the driven conveyor belt 29, and then the plastic part will move down stably. During this period, the crushing knife 4 reciprocates, and the plastic part can be chopped, which can ensure that the crushing knife 4 stably chops the plastic part and can realize automatic feeding and auxiliary crushing.

[0046] As Figure 3 , Figure 4 , Figure 15 , Figure 16As shown, the fine crushing component includes a fine crushing cylinder 11, a tool rest 12, and a fine crushing shaft 14. One side of the fine crushing cylinder 11 is provided with a feed hole. The feed pipe 2 and the tool rest 12 are fixed on the outer periphery of the fine crushing cylinder 11. The feed pipe 2 is communicated with the feed hole. One side of the tool rest 12 is fixedly provided with a fixed cutter 13. The feed pipe 2 is fixed to the fixed cutter 13. Through holes are provided on both sides of the fine crushing cylinder 11 that are far away from each other. The fine crushing shaft 14 rotates inside the through holes. A number of rotary cutters 15 are arranged inside the fine crushing cylinder 11. The fixed cutter 13 is matched with the rotary cutters 15. A number of cutter bars 16 are fixedly arranged between one side of the rotary cutter 15 and the outer periphery of the fine crushing shaft 14. The lower part of the fine crushing cylinder 11 is provided with a discharge hole. An arc-shaped net 17 is fixedly arranged inside the discharge hole. The arc-shaped net 17 includes a number of mesh holes. A discharge hopper 18 is fixedly arranged on the outer periphery of the lower part of the fine crushing cylinder 11. A chassis and a motor 19 are sequentially fixedly arranged on the upper side of the bottom plate 1. The shaft end of the motor 19 and the outer periphery of the fine crushing shaft 14 are connected by belt and pulley transmission. When it is necessary to crush plastic parts, the motor 19 needs to be started. The motor 19 will drive the fine crushing shaft 14 and the rotary cutters 15 to rotate. The plastic parts clamped between the active conveyor belt 23 and the driven conveyor belt 29 will gradually approach the fine crushing cylinder 11 after rough crushing. When the plastic parts contact the fixed cutter 13 and continue to move downward, they can be cut by the rotary cutters 15 and then fall into the fine crushing cylinder 11. The plastic in the fine crushing cylinder 11 will fall on the arc-shaped net 17. At this time, the smaller plastic particles can pass through the arc-shaped net 17, while the larger plastic particles will be blocked by the arc-shaped net 17. And a part of the larger plastic blocks will be located in the mesh holes of the arc-shaped net 17. Then when the rotary cutters 15 rotate, a shearing force can be formed at the edges of the rotary cutters 15 and the mesh holes, and the plastic blocks that cannot pass through the arc-shaped net 17 can be cut again. During the rotation of the rotary cutters 15, the larger plastic blocks can be continuously crushed until all the plastic blocks are crushed into small plastic particles, so as to achieve fine crushing. Moreover, during the crushing process, the dust attached to the plastic blocks can be knocked off. A first vertical frame 20 and a second vertical frame 21 are fixedly arranged on the upper side of the bottom plate 1. The fine crushing cylinder 11 and the feed pipe 2 are fixed on the first vertical frame 20. The fine crushing cylinder 11 is fixed on the second vertical frame 21.

[0047] As Figure 7 , Figure 8 , Figure 13 , Figure 14As shown, the fine crushing component is used to drive the coarse crushing component. Specifically: on both sides of the feed pipe 2 away from each other, there are coarse crushing shafts 7. A connecting frame 8 is rotatably arranged on the outer periphery of the coarse crushing shaft 7, and the connecting frame 8 is fixed on the outer wall of the feed pipe 2. A rotating disk 9 is fixedly arranged on the outer periphery of the coarse crushing shaft 7. A connecting rod 10 is rotatably arranged on one side of the rotating disk 9, and the other end of the connecting rod 10 is rotatably arranged on one side of the gantry 6. The outer periphery of the fine crushing shaft 14 and the outer periphery of the coarse crushing shaft 7 are connected by belt and pulley transmission. When crushing plastics, the fine crushing shaft 14 will rotate. The fine crushing shaft 14 will drive the coarse crushing shaft 7 to rotate through the belt and pulley. When the coarse crushing shaft 7 rotates, it can make the gantry 6 do reciprocating motion through the rotating disk 9 and the connecting rod 10. The gantry 6 will drive the connecting rod 5, the tool holder 3 and the fragmentation knife 4 to move together, so that the fragmentation knife 4 can move reciprocally automatically, and thus automatic coarse crushing can be realized. The fine crushing component is used to drive the feeding component. Specifically: a connecting shaft 31 is rotatably arranged on the outer wall of the feed pipe 2. The outer periphery of the connecting shaft 31 and the outer periphery of the fine crushing shaft 14 are connected by belt and pulley transmission. The outer periphery of the connecting shaft 31 and the outer periphery of a driving shaft 22 are connected by gear transmission. During operation, the rotation speed of the fine crushing shaft 14 is higher than that of the driving shaft 22. When the fine crushing shaft 14 rotates, it will drive the connecting shaft 31 to rotate through the belt and pulley. When the connecting shaft 31 rotates, it will drive a driving shaft 22 to rotate through the gear. When one driving shaft 22 rotates, it can drive another driving shaft 22 to rotate through the driving conveyor belt 23, so that the driving conveyor belt 23 rotates, and thus automatic feeding can be realized.

[0048] As Figure 3 , Figure 5 , Figure 11 , Figure 15As shown in the figure, a screening component is provided below the fine crushing component. The screening component is used to separate the crushed plastic particles from the powder dust. The screening component includes an inclined hopper 33. There is an installation hole on the lower side of the inclined hopper 33. A screen 34 is fixedly arranged inside the installation hole. The inclined hopper 33 is located below the discharge hopper 18. An inclined baffle 35 and a number of guide rods 36 are fixedly arranged on the lower side of the inclined hopper 33. A guide frame 37 is slidably arranged on the outer periphery of the guide rod 36. The lower end of the guide frame 37 is fixed on the upper side of the bottom plate 1. The coarse crushing component is used to drive the screening component to perform automatic shaking screening. Specifically: The gantry 6 is fixed on the outer wall of the inclined hopper 33. Two side baffles 38 are fixedly arranged on the upper side of the inclined hopper 33. A dust collection box is in contact with the upper side of the bottom plate 1. The plastic crushed into small particles will fall into the discharge hopper 18 and then fall onto the screen 34 through the discharge hopper 18. The small particle plastics cannot pass through the screen 34, while the powdery dust can pass through the screen 34. When the gantry 6 moves reciprocally, it will drive the inclined hopper 33, the screen 34, the guide rod 36, and the inclined baffle 35 to move together, so that the screen 34 can perform automatic reciprocating shaking screening. When the screen 34 performs automatic reciprocating shaking screening, the small particle plastics on the screen 34 will gradually move down along the upper surface of the screen 34, which can prevent the small particle plastics from accumulating on the screen 34. At the same time, the powdery dust will pass through the screen 34 and fall into the dust collection box, so as to realize automatic shaking screening separation. During use, it is necessary to regularly clean the dust in the dust collection box.

[0049] As Figure 1 , Figure 5 , Figure 6 , Figure 12 , Figure 16As shown in the figure, a conveying component is provided on one side of the screening component. The conveying component is used to convey the crushed plastic particles. The screening component and the conveying component are located above the bottom plate 1. The conveying component includes a ventilation conveying pipe 39 and an aggregate hopper 40. The ventilation conveying pipe 39 is fixed on the upper side of the bottom plate 1, and the aggregate hopper 40 is fixed on the second vertical frame 21. Square holes are provided on the outer periphery of the ventilation conveying pipe 39, and the aggregate hopper 40 is fixed inside the square holes. The inclined sieve hopper 33 slides on one side of the aggregate hopper 40. The small particle plastics gradually moving down along the upper surface of the sieve mesh 34 will gradually fall into the aggregate hopper 40. The small particle plastics in the aggregate hopper 40 will automatically fall into the ventilation conveying pipe 39. One end of the ventilation conveying pipe 39 is provided with a air supply component. The air supply component includes a cover plate 41 and a connector 45. A air supply housing 42 is rotatably provided on the outer periphery of the fine crushing shaft 14. A number of support frames 43 are fixed on the outer periphery of the air supply housing 42, and the support frames 43 are fixed on one side of the fine crushing cylinder 11. The cover plate 41 is fixed on one side of the air supply housing 42. An air inlet hole is provided on one side of the cover plate 41. The fine crushing component is used to drive the conveying component. Specifically, a centrifugal impeller 44 is fixed at one end of the fine crushing shaft 14. The centrifugal impeller 44 is located inside the air supply housing 42. The centrifugal impeller 44 includes a circular plate, an annular plate and a number of blades. The blades are fixed between the circular plate and the annular plate. A wind guiding cone is fixed on one side of the circular plate. The connector 45 is fixed on one end of the ventilation conveying pipe 39, and the connector 45 is fixed on the air supply housing 42 and the cover plate 41. During operation, the fine crushing shaft 14 will drive the centrifugal impeller 44 to rotate at a high speed. When the centrifugal impeller 44 rotates at a high speed, wind pressure air flow will be generated by centrifugal force. The air flow will enter the ventilation conveying pipe 39 through the connector 45. A strong air flow will be formed in the ventilation conveying pipe 39. The strong air flow in the ventilation conveying pipe 39 will blow away the small particle plastics falling into the ventilation conveying pipe 39, and then be discharged through the other end of the ventilation conveying pipe 39, so as to be able to convey the small particle plastics and realize automatic conveying. A wind pressure baffle 46 is fixed inside the ventilation conveying pipe 39. The wind pressure baffle 46 can prevent the air flow from blowing into the aggregate hopper 40, so as to prevent the occurrence of turbulent flow.
