[0015] The present invention is provided with a rotating heating rod. After the stirring motor is started, the rotating heating rod rotates along with the stirring motor, and the rotating heating rod stirs and heats the waste material dropped into the stirring barrel. When the rotating heating rod stirs and heats the waste material in the stirring barrel, a large amount of heat is generated in the stirring barrel. The heat in the stirring barrel rises upward and is used to heat the crushing parts, so that the crushing parts are heated and heated. After the EPE foam plastic waste contacts the heated crushing parts, it shrinks due to the heat, and the surface of the EPE foam plastic waste becomes wrinkled and rough, thereby increasing the friction between the EPE foam plastic waste and the multiple crushing knives, so that the EPE foam plastic waste is crushed more thoroughly, the crushing of the EPE foam plastic waste is accelerated, and the work efficiency is improved.

[0016] By setting the heat conduction plate, the heat in the mixing barrel is transferred in sequence through the heat conduction guide plate, the heat conduction protective shell and the heat conduction outer shell, and finally transferred to the heat conduction plate. After the conveyor belt feeds for a certain period of time, the conveyor belt stops, and the sliding extrusion plate moves downward to squeeze the EPE foam plastic waste, thereby accelerating the crushing of the EPE foam plastic waste.

[0017] By arranging a scraping plate, when the crushing knife rotates with the crushing piece, the crushing knife will abut against the scraping plate, causing the scraping plate to flip upward. When the crushing knife pushes the scraping plate to flip upward, the scraping plate can scrape out the EPE foam plastic waste adhering to the crushing knife, and when the crushing knife pushes the scraping plate to flip upward, friction will be generated between the crushing knife and the scraping plate, and the friction will generate heat, which will further increase the temperature of the crushing knife, causing the EPE foam plastic waste to shrink due to the heat, and then making the surface of the EPE foam plastic waste wrinkled and rough, thereby increasing the friction between the EPE foam plastic waste and the multiple crushing knives, making the EPE foam plastic waste crushed more thoroughly, accelerating the crushing of the EPE foam plastic waste, and improving work efficiency.

[0018] The scraper blade is then pulled back by the blade to remove the EPE foam plastic waste from the upper end of the scraper blade, thereby preventing the EPE foam plastic waste from adhering to the upper end of the scraper blade. When the crushing knife pushes the scraper blade to turn upward, the EPE foam plastic waste adhering to the upper end of the scraper blade is transferred to the crushing knife, thereby preventing the EPE foam plastic waste from adhering to the crushing knife, thereby affecting the overall crushing efficiency of the EPE foam plastic waste; when the stirring member rotates at a faster speed, the scraper blade is pulled back by the blade to remove the EPE foam plastic waste from the crushing knife, thereby preventing the EPE foam plastic waste from adhering to the crushing knife, thereby affecting the overall crushing efficiency of the EPE foam plastic waste; when the stirring member rotates at a faster speed, the scraper blade is pulled back by the blade to remove the EPE foam plastic waste from the crushing knife, thereby causing the EPE foam plastic waste adhering to the scraper blade or the crushing knife to fall off, thereby maintaining the sharpness of the crushing knife and improving the crushing efficiency of the stirring member.

[0019] The invention has a simple structure and can recycle EPE foam plastic waste to prevent environmental pollution caused by EPE foam plastic waste. By recycling and utilizing EPE foam plastic waste, raw materials are saved, environmentally friendly production is achieved, energy is saved and emissions are reduced. By setting a crushing device, the recycling of waste can be accelerated and the recycling efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

The heat conducting plate 421 is installed at the bottom of the sliding extrusion plate 420, so that the heat conducting plate 421 will squeeze and contact the upper layer of the EPE foam plastic waste, so that the upper layer of the EPE foam plastic waste will shrink due to heat, thereby making the surface of the EPE foam plastic waste wrinkled and rough, thereby increasing the friction between the EPE foam plastic waste and the multiple crushing knives 233, so that the EPE foam plastic waste is crushed more thoroughly, accelerating the crushing of the EPE foam plastic waste, and improving work efficiency.

[0047] 4. When the crushing blade 233 rotates following the crushing piece 23, the crushing blade 233 will abut against the scraping plate 52, causing the scraping plate 52 to flip upward. When the crushing blade 233 pushes the scraping plate 52 to flip upward, the scraping plate 52 can scrape out the EPE foam plastic waste adhering to the crushing blade 233, and when the crushing blade 233 pushes the scraping plate 52 to flip upward, friction will be generated between the crushing blade 233 and the scraping plate 52, and the friction will generate heat, thereby further increasing the temperature of the crushing blade 233, causing the EPE foam plastic waste to shrink due to the heat, and then making the surface of the EPE foam plastic waste wrinkled and rough, thereby increasing the friction between the EPE foam plastic waste and the multiple crushing blades 233, so that the EPE foam plastic waste is crushed more thoroughly, accelerating the crushing of the EPE foam plastic waste, and improving work efficiency.

[0048] 5. When the stirring member 34 rotates slowly, after the scraper plate 52 breaks away from the crushing knife 233, the scraper plate 52 recovers. Under the action of inertia, the middle part of the scraper plate 52 will hit the intercepting rod 53, so that the upper end of the scraper plate 52 can throw out the EPE foam plastic waste on the upper end of the scraper plate 52 under the action of inertia or centrifugal force, preventing the EPE foam plastic waste from adhering to the upper end of the scraper plate 52. Then, when the crushing knife 233 pushes the scraper plate 52 to turn upward, the EPE foam plastic waste adhering to the upper end of the scraper plate 52 is transferred to the crushing knife 233, preventing EPE foam plastic waste from adhering to the crushing knife 233, thereby affecting the overall crushing efficiency of the EPE foam plastic waste; when the stirring member 34 rotates at a faster speed, after the scraping plate 52 breaks away from the crushing knife 233, the scraping plate 52 recovers, and under the action of inertia, the upper end of the scraping plate 52 will knock on the other part of the crushing knife 233, thereby causing the EPE foam plastic waste adhering to the scraping plate 52 or the crushing knife 233 to fall off, thereby maintaining the sharpness of the crushing knife 233 and improving the crushing efficiency of the stirring member 34. The EPE foam plastic waste on the upper end of the scraper plate 52 cannot be thrown out due to inertia or centrifugal force. Since the scraper plate 52 is located in the heat-conducting protective shell 221 and is adjacent to the mixing barrel 32, the mixing barrel 32 can receive more heat, thereby melting the EPE foam plastic waste adhering to the scraper plate 52. The melted EPE foam plastic waste finally flows into the mixing barrel 32 after passing through the scraper plate 52, the heat-conducting protective shell 221 and the heat-conducting guide plate 31, preventing the EPE foam plastic waste from adhering to the scraper plate 52, thereby reducing the crushing efficiency of the crushing unit 23.

[0049] 6. The EPE foam plastic waste is heated, stirred and melted in the mixing barrel 32 to form plastic liquid. After heating and stirring for a period of time, the electric valve 35 is opened, and the plastic liquid flows out from the discharge port. The guide pipe 36 is sufficient to prevent the plastic liquid from splashing. The electric valve 35 is closed after being opened for a certain period of time, and the plastic liquid is cut off and falls into the cooling tank 37. After the plastic liquid is cut off and falls into the cooling tank 37 for cooling, the electric valve 35 continues to open, so that the remaining plastic liquid continues to flow out from the discharge port. This is repeated, and the coolant is cooled in the cooling tank 37 to form plastic strips. After the plastic strips are cooled, they are taken out and placed on the conveyor belt 61. Driven by the conveyor belt 61, they move toward the cutting piece 62. After being cut by the cutting piece 62, the plastic strips continue to be transported by the conveyor belt 61 and finally fall into the collecting piece 63 to complete the recycling, thereby reducing the production cost of foam plastics and improving production efficiency for subsequent foam plastic production.

[0050] The present invention is provided with a rotating heating rod 341. After the stirring motor 340 is started, the rotating heating rod 341 rotates along with the stirring motor 340. The rotating heating rod 341 stirs and heats the waste material dropped into the stirring barrel 32. When the rotating heating rod 341 stirs and heats the waste material in the stirring barrel 32, a large amount of heat will be generated in the stirring barrel 32. The heat in the stirring barrel 32 rises upward to heat the crushing piece 23, so that the crushing piece 23 is heated and heated. After the EPE foam plastic waste contacts the heated crushing piece 23, it shrinks due to the heat, thereby making the surface of the EPE foam plastic waste wrinkled and rough, thereby increasing the friction between the EPE foam plastic waste and the multiple crushing knives 233, so that the EPE foam plastic waste is crushed more thoroughly, the crushing of the EPE foam plastic waste is accelerated, and the work efficiency is improved.

[0051] By providing the heat conducting plate 421, the heat in the mixing barrel 32 is transferred in sequence through the heat conducting material guide plate 31, the heat conducting protective shell 221 and the heat conducting outer shell 410, and finally transferred to the heat conducting plate 421. After the conveyor belt 12 has been feeding for a certain period of time, the conveyor belt 12 stops, and the sliding extrusion plate 420 moves downward to squeeze the EPE foam plastic waste, thereby accelerating the crushing of the EPE foam plastic waste. At the same time, when the sliding extrusion plate 420 moves downward, the heat conducting plate 421 will follow the sliding extrusion plate 420 to move downward. The heat conducting plate 421 is installed at the bottom of the sliding extrusion plate 420, so that the heat conducting plate 421 will squeeze and contact the upper layer of the EPE foam plastic waste, so that the EPE foam plastic waste on the upper layer shrinks due to heat, and the surface of the EPE foam plastic waste becomes wrinkled and rough, thereby increasing the friction between the EPE foam plastic waste and the multiple crushing knives 233, so that the EPE foam plastic waste is crushed more thoroughly, accelerating the crushing of the EPE foam plastic waste, and improving work efficiency.

[0052] By setting the scraping plate 52, when the crushing knife 233 rotates following the crushing piece 23, the crushing knife 233 will abut against the scraping plate 52, causing the scraping plate 52 to flip upward. While the crushing knife 233 pushes the scraping plate 52 to flip upward, the scraping plate 52 can scrape out the EPE foam plastic waste adhering to the crushing knife 233, and when the crushing knife 233 pushes the scraping plate 52 to flip upward, friction will be generated between the crushing knife 233 and the scraping plate 52, and the friction will generate heat, thereby further increasing the temperature of the crushing knife 233, causing the EPE foam plastic waste to shrink due to the heat, and then making the wrinkles on the surface of the EPE foam plastic waste become rough, thereby increasing the friction between the EPE foam plastic waste and the multiple crushing knives 233, so that the EPE foam plastic waste is crushed more thoroughly, the crushing of the EPE foam plastic waste is accelerated, and the work efficiency is improved.

[0053] By setting the scraper plate 52, when the stirring member 34 rotates slowly, after the scraper plate 52 breaks away from the crushing knife 233, the scraper plate 52 recovers, and under the action of inertia, the middle part of the scraper plate 52 will hit the intercepting rod 53, so that the upper end of the scraper plate 52 can throw out the EPE foam plastic waste on the upper end of the scraper plate 52 under the action of inertia or centrifugal force, preventing the upper end of the scraper plate 52 from being adhered to the EPE foam plastic waste, and then when the crushing knife 233 pushes the scraper plate 52 to turn upward, the EPE foam plastic waste adhered to the upper end of the scraper plate 52 is transferred to the crushing blade 233, preventing EPE foam plastic waste from adhering to the crushing blade 233, thereby affecting the overall crushing efficiency of the EPE foam plastic waste; when the stirring member 34 rotates at a faster speed, after the scraping plate 52 breaks away from the crushing blade 233, the scraping plate 52 recovers, and under the action of inertia, the upper end of the scraping plate 52 will knock on the other part of the crushing blade 233, thereby causing the EPE foam plastic waste adhering to the scraping plate 52 or the crushing blade 233 to fall off, thereby maintaining the sharpness of the crushing blade 233 and improving the crushing efficiency of the stirring member 34.

[0054] The invention has a simple structure and can recycle EPE foam plastic waste to prevent environmental pollution caused by EPE foam plastic waste. By recycling and utilizing EPE foam plastic waste, raw materials are saved, environmentally friendly production is achieved, energy is saved and emissions are reduced. By setting a crushing device, the recycling of waste can be accelerated and the recycling efficiency can be improved.
