Description

Technical Field

[0001] This invention relates to the field of injection molding technology, specifically to a waste material remanufacturing injection molding apparatus and method. Background Technology

[0002] Waste recycling injection molding equipment is a core piece of equipment in the field of plastic recycling and reuse, widely used in plastic product manufacturing enterprises, waste plastic recycling and processing plants, and other locations. With increasingly stringent environmental protection requirements and the growing popularity of the concept of plastic resource recycling, the recycling and remanufacturing of waste plastics has become an important direction for the sustainable development of the plastics industry. As one of the main processes for plastic waste recycling, injection molding's production efficiency and product quality directly affect the economic and environmental benefits of the plastic recycling industry. Therefore, efficient and stable waste recycling injection molding equipment has become an urgent need for the industry's development.

[0003] Currently, most existing waste material remanufacturing injection molding equipment adopts a split structure. After the waste material is crushed and screened, qualified materials need to be manually transferred to the feed hopper of the injection molding machine. The vibration generated during the screening process is directly transmitted to the equipment base. This type of equipment has obvious shortcomings. Manual transfer is not only inefficient and increases labor costs, but it also easily leads to production interruptions and makes continuous production impossible.

A fixed frame 12 is fixedly connected inside the bed body 10, which realizes the fixed installation of the screen plate 13, supports the weight of the screen plate 13, and ensures that the screen plate 13 does not deform during vibration. The screen plate 13 is fixedly connected inside the fixed frame 12, which realizes the screening of crushed plastic materials, separation of qualified particles and unqualified large particles, and guidance of materials to move towards the discharge port. Multiple screen holes are opened on the surface of the screen plate 13.

[0039] The bed body 10 is externally fixedly connected to a fixing plate 17, which realizes the fixed installation of the support plate 18, provides a support base for the storage hopper 19, and ensures that the storage hopper 19 is installed firmly. The top of the fixing plate 17 is fixedly connected to the support plate 18, which realizes the support of the weight of the storage hopper 19 and the crushing pipe 20, raises the installation height of the storage hopper 19, and ensures that the waste can enter the crushing pipe 20 by gravity. The top of the support plate 18 is fixedly connected to the storage hopper 19, which realizes the temporary storage of plastic waste to be processed, guides the waste to enter the crushing pipe 20 evenly, and prevents the waste from spilling. The bottom of the storage hopper 19 extends to the upper interior of the bed body 10. The inside of the storage hopper 19 is fixedly connected to the crushing pipe 20, which realizes the function of accommodating the crushing roller 27, providing a closed space for the waste crushing process, and guiding the crushed material to fall into the bed body 10. The outside of the storage hopper 19 is fixedly connected to an installation plate 21, which realizes the fixed installation of the single-axis motor 22, provides a stable installation base for the motor, and ensures that the motor does not shake during operation.

[0040] A single-axis motor 22 is fixedly connected to the outside of the mounting plate 21, which provides power for the rotation of the crushing roller 27, drives the gear set to rotate synchronously, and ensures the continuous crushing process. The output end of the single-axis motor 22 is fixedly connected to the output shaft 23, which transmits the output power of the single-axis motor 22, drives the first circular gear 24 and one of the crushing rollers 27 to rotate synchronously, and ensures the stable power transmission. The output shaft 23 is fixedly connected to the outside of the first circular gear 24, which meshes with the second circular gear 26, transmits power to the rotating shaft 25, and drives the two crushing rollers 27 to rotate synchronously in opposite directions. The crushing tube 20 is rotatably connected to the rotating shaft 25, which transmits the power of the second circular gear 26, drives the other crushing roller 27 to rotate synchronously, and ensures the relative rotation of the two crushing rollers 27.

[0041] A second spur gear 26 is fixedly connected to the outside of the rotating shaft 25, which realizes the meshing transmission with the first spur gear 24, changes the rotation direction of the power, and drives the rotating shaft 25 to rotate synchronously in the opposite direction. The first spur gear 24 and the second spur gear 26 are meshed. One end of the rotating shaft 25 and the output shaft 23 both extend into the inside of the crushing tube 20. Crushing rollers 27 are fixedly connected to the outside of the rotating shaft 25 and the output shaft 23, which realizes the squeezing, shearing and crushing of the plastic waste entering the crushing tube 20, crushing large pieces of waste into small particles with uniform particle size, and ensuring the quality of subsequent screening and injection molding.

[0042] Two crushing rollers 27 work together to crush the waste material entering the crushing tube 20. The crushed waste material falls into the bed body 10. A transfer bed 28 is fixedly connected to the top of the base 1, which realizes the fixed installation of the conveyor belt 29, provides running space for the conveyor belt 29, and ensures the smooth operation of the conveyor belt 29. The transfer bed 28 is equipped with a conveyor belt 29, which realizes the automatic and continuous conveying of qualified materials after screening, and transfers the qualified materials from the screen discharge port 15 to the feed hopper 3 of the injection molding machine 2, realizing the seamless connection between waste pretreatment and injection molding. The feed end of the conveyor belt 29 corresponds to the position of the screen discharge port 15. A waste collection cart 30 is placed on the top of the base 1, which realizes the collection of unqualified large particles after screening, facilitates the transfer and secondary crushing of unqualified materials, and keeps the production site clean.

[0043] The top opening of the waste collection vehicle 30 corresponds to the position of the waste discharge port 16. The injection molding assembly includes an injection molding machine 2 and a feeding hopper 3. The injection molding machine 2 realizes the effects of heating and melting qualified waste particles, injecting molten plastic into the mold cavity under high pressure, and completing the product pressure holding, cooling and automatic demolding. The feeding hopper 3 realizes the effects of temporarily storing qualified materials conveyed by the conveyor belt 29, guiding the materials to enter the barrel of the injection molding machine 2 evenly, and preventing the materials from spilling. The bottom of the injection molding machine 2 is fixedly connected to the top of the base 1, and the feeding hopper 3 is fixedly connected to the top of the feeding end of the injection molding machine 2. The discharge end of the conveyor belt 29 extends to the top of the feeding hopper 3. The conveyor belt 29 can transport the screened qualified waste to the inside of the feeding hopper 3.

[0044] The device is used as follows: Waste crushing: The plastic waste to be processed is evenly fed into the storage hopper 19. Under the action of gravity, the waste enters the internal cavity of the crushing tube 20. The single-shaft motor 22 drives the first spur gear 24 to rotate through the output shaft 23. The first spur gear 24 meshes with and drives the second spur gear 26 and the rotating shaft 25 to rotate synchronously in opposite directions, thereby driving the two crushing rollers 27 to rotate relative to each other. The waste entering the crushing tube 20 is squeezed, sheared and crushed, breaking large irregular pieces of waste into smaller particles with uniform particle size. The crushed waste is discharged from the bottom of the crushing tube 20 and falls onto the screen plate 13 inside the bed 10. The vibrating motor 11 drives the bed 10 to generate high-frequency vibration. The spring 7 and damper 6 inside the support leg 4 work together to absorb the vibration energy and prevent the vibration from being transmitted to the base 1. The screen plate 13 vibrates synchronously with the bed 10, so that the crushed waste is evenly distributed on the surface of the screen plate 13. Dispersed and moving forward, qualified particles with a diameter smaller than the sieve holes pass through the sieve holes and are discharged from the sieve discharge port 15 at the end of the bed 10. Large waste particles with a diameter larger than the sieve holes move along the surface of the sieve plate 13 and fall into the waste collection cart 30 below from the waste discharge port 16 at the other end of the bed 10. Qualified waste particles discharged from the sieve discharge port 15 fall onto the conveyor belt 29 inside the transfer bed 28. The conveyor belt 29 runs continuously at a uniform speed, smoothly transporting the qualified waste particles to the feed hopper 3 at the top of the injection molding machine 2, completing the automatic continuous transfer of waste. The injection molding machine 2 heats and melts the qualified waste particles in the feed hopper 3, turning the solid waste into a uniform molten plastic melt. Then, the plastic melt is injected into the preset mold cavity under high pressure through the screw. After the pressure holding and cooling and shaping stages, the mold automatically opens and the cooled and shaped injection molded product is taken out, completing the reshaping and molding process of the waste.

[0045] Working Principle: When the device is in use, the plastic waste is first crushed. The collected plastic waste is evenly fed into the storage hopper 19. Under its own gravity, the waste enters the internal cavity of the crushing tube 20 from the bottom of the storage hopper 19. The single-shaft motor 22 starts running, driving the output shaft 23 to rotate synchronously. During the rotation of the output shaft 23, the first spur gear 24 rotates synchronously. The first spur gear 24 drives the second spur gear 26 to rotate synchronously in the opposite direction through meshing transmission. The second spur gear 26 drives the rotating shaft 25 to rotate synchronously in the opposite direction. During the rotation of the output shaft 23 and the rotating shaft 25, they drive their respective external crushing rollers 27 to rotate synchronously relative to each other. The two crushing rollers 27 cooperate with each other to squeeze, shear, and crush the plastic waste that has entered the crushing tube 20, breaking large, irregular pieces of plastic waste into smaller granular materials. Under the action of gravity, the crushed material is discharged from the bottom opening of the crushing tube 20 and falls onto the screen plate 13 inside the lower bed 10.

[0046] The crushed material enters the vibrating screening stage, and the vibrating motor 11 starts running, driving the bed 10 to generate high-frequency reciprocating vibration. The spring 7 and damper 6 inside the support leg 4 work together to absorb the vibration energy generated by the bed 10, preventing the vibration from being transmitted to the base 1 and ensuring the overall stability of the device. The screen plate 13 vibrates synchronously with the bed 10, so that the crushed material falling on the surface of the screen plate 13 is evenly dispersed and moves along the surface of the screen plate 13 towards the screen discharge port 15 under the action of vibration. During the material movement, qualified material particles with a particle size smaller than the screen holes of the screen plate 13 pass through the screen holes and fall into the bottom cavity of the bed 10, and then flow along the inclined surface of the bottom of the bed 10 towards the screen discharge port 15, and finally are discharged from the bed 10 from the screen discharge port 15. Large, non-compliant particles larger than the sieve holes of the sieve plate 13 cannot pass through the sieve holes and continue to move along the surface of the sieve plate 13 toward the waste discharge port 16. Guided by the guide block 14, they are discharged from the bed 10 through the waste discharge port 16 and fall into the waste collection vehicle 30 placed below.

[0047] After screening, the qualified materials are transferred. The qualified material particles discharged from the screening outlet 15 fall directly onto the conveyor belt 29 inside the transfer bed 28. Driven by the drive device, the conveyor belt 29 runs continuously at a constant speed, smoothly conveying the qualified material particles onto it forward. The discharge end of the conveyor belt 29 extends above the top feed hopper 3 of the injection molding machine 2. When the material particles are conveyed to the discharge end of the conveyor belt 29, they fall off the surface of the conveyor belt 29 under the action of gravity and fall into the interior of the feed hopper 3, completing the automatic continuous transfer process of qualified materials.

[0048] Qualified materials enter the injection molding stage. The qualified material particles falling into the feed hopper 3 are drawn into the barrel of the injection molding machine 2 under gravity. The heating system of the injection molding machine 2 heats the barrel, causing the plastic particles inside to gradually melt and transform into a uniform molten plastic. The screw of the injection molding machine 2 rotates, pushing the molten plastic forward and generating sufficient pressure through the screw's extrusion action. When the melt pressure reaches the set value, the injection device of the injection molding machine 2 starts, injecting the molten plastic into the pre-installed mold cavity at high speed and high pressure. After the melt fills the mold cavity, it enters the holding pressure stage, maintaining a certain pressure to compensate for the volume change caused by the cooling shrinkage of the melt. After the holding pressure ends, the molten plastic inside the mold gradually cools and solidifies. When it cools to the set temperature, the mold automatically opens, and the ejector device of the injection molding machine 2 ejects the cooled and solidified injection molded product from the mold cavity, completing one injection molding process.

S3. The qualified waste particles discharged from the screen outlet (15) fall onto the conveyor belt (29) inside the transfer bed (28). The conveyor belt (29) runs at a constant speed, smoothly transporting the qualified waste particles to the feed hopper (3) at the top of the injection molding machine (2), thus completing the automatic continuous transfer of waste. S4. The injection molding machine (2) heats and melts the qualified waste particles in the feed hopper (3) to transform the solid waste into a uniform molten plastic melt. Then, the plastic melt is injected into the preset mold cavity under high pressure through the screw. After the pressure holding and cooling and shaping stages, the mold automatically opens and the cooled and shaped injection product is taken out, completing the waste reshaping process.
