Description

Technical Field

[0001] This application relates to the field of plastic processing and recycled resource utilization technology, specifically to a device for recycling and reproducing conductive plastic masterbatch. Background Technology

[0002] With increasingly stringent environmental protection requirements in industrial production and consumer markets, the recycling of waste plastics has become a global focus. Especially in the electronics industry, conductive plastics are widely used in various electronic products due to their unique properties. However, the disposal of these products not only causes environmental pollution but also wastes a significant amount of valuable resources. Traditional plastic recycling technologies mostly focus on the physical recycling of ordinary plastics, while the recycling and processing technologies for functional plastics, especially conductive plastics, are relatively outdated and fail to meet the demands for efficient recycling and reuse.

[0003] Currently, there are two main methods for recycling conductive plastic masterbatches: one is to decompose the plastic into basic chemicals through high-temperature pyrolysis. While this method can decompose the plastic, it generates toxic gases and is energy-intensive and uneconomical. The other method is to extract useful components using chemical solvents. Although this method can better preserve the characteristics of the raw materials, it is costly, has a low solvent recovery rate, and is prone to secondary pollution. In addition, there is the mechanical crushing and remolding method, but this method cannot effectively remove impurities from the plastic, leading to unstable final product quality.

[0004] Regardless of the existing recycling methods, they all suffer from problems such as low efficiency, high cost, or significant environmental impact. Especially when dealing with special plastics such as conductive plastics, existing technologies often cannot balance economic benefits and environmental protection requirements, which seriously limits the development and application of conductive plastic masterbatch recycling technology. In order to solve the above problems, a conductive plastic masterbatch recycling and reprocessing device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a conductive plastic masterbatch recycling and reprocessing device, which improves the recycling rate of conductive plastic masterbatch and the quality of recycled products, reduces recycling costs, reduces environmental pollution, and achieves efficient and environmentally friendly recycling and reuse of conductive plastic masterbatch.

[0006] To achieve the above objectives, this application provides the following technical solution: a conductive plastic masterbatch recycling and reprocessing device, comprising a base plate and a processing cylinder. An annular heating plate is installed on the inner wall of the processing cylinder. A servo motor is fixedly connected to one side of the processing cylinder, and a screw conveyor is fixedly connected to the output shaft end of the servo motor. The screw conveyor is located inside the processing cylinder, and a conveying pipe is connected to the output end of the processing cylinder. A cooling box is fixedly connected to the other side of the processing cylinder, and the cooling box is fitted outside the conveying pipe. A spiral cooling pipe is provided inside the cooling box and fitted outside the conveying pipe. A liquid storage tank is fixedly connected to the upper surface of the base plate, and two liquid pumps are installed on the top of the liquid storage tank. The top ends of the two liquid pumps are respectively connected to the two bottom ends of the spiral cooling pipe. A cutting mechanism is provided outside the cooling box.

[0007] The above solution significantly improves the recycling rate of conductive plastic masterbatch, enabling more waste materials to be transformed back into valuable products and reducing resource waste. The conductive plastic waste to be processed is fed into the processing drum. The ring heating plate and servo motor gradually heat and stably convey the waste, rapidly melting it at high temperatures. The waste is then extruded into strips through the output end of the processing drum and transported to a cooling tank for cooling. A spiral cooling pipe, liquid storage tank, and liquid pump rapidly cool and solidify the strips. Finally, a cutting mechanism cuts them into standard-sized granules, completing the recycling process. Through scientific and reasonable equipment design and process optimization, the cost of recycling and processing is significantly reduced, enhancing the economic benefits for enterprises.

[0008] Furthermore, the cutting mechanism includes a cylinder fixedly connected to the upper surface of the cooling box, and a cutting blade is fixedly connected to the output end of the cylinder, the cutting blade being located above the conveying pipe.

[0009] The above scheme allows for the cutting of cooled long strips of material into standard-sized small particles by setting up a cutting mechanism.

[0010] Furthermore, a collection box is fixedly connected to the upper surface of the base plate, and the collection box is located below the conveying pipe.

[0011] The above solution allows for the collection of finished recycled products by setting up collection boxes, which is convenient for operation.

[0012] Furthermore, a controller is installed on the outer surface of the processing cylinder, and the annular heating plate, servo motor, liquid pump and cylinder are all electrically connected to the controller.

[0013] The above solution allows for convenient control of the electrical components in the device by setting up a controller, simplifying the operation.

[0014] Furthermore, support columns are fixedly connected to the four corners of the bottom surface of the base plate.

[0015] The above solution allows the device to be placed more stably on the contact surface by setting up support columns.

[0016] Furthermore, a hopper is installed at the top of the processing cylinder, and the output end of the hopper is connected to the interior of the processing cylinder.

[0017] The above scheme allows for the feeding of conductive plastic waste into the processing cylinder via a hopper, facilitating the recycling and regeneration of conductive plastic waste.

[0018] Furthermore, an inlet is installed on the outer surface of the liquid storage tank, and the output end of the inlet is connected to the interior of the liquid storage tank.

[0019] The above solution allows for the convenient addition of an appropriate amount of coolant to the storage tank by setting up an inlet.

[0020] Furthermore, a drain port is installed on the ground of the liquid storage tank, and the input end of the drain port is connected to the interior of the liquid storage tank.

[0021] The above solution allows the coolant in the reservoir to be drained to the outside by setting a drain port, making it convenient to replace the coolant in the reservoir.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This conductive plastic masterbatch recycling and reprocessing device significantly improves the recycling rate of conductive plastic waste and reduces resource waste. The device feeds the conductive plastic waste into a processing cylinder and activates a ring-shaped heating plate and servo motor to achieve gradual heating and stable conveying. Under high temperature, the conductive plastic waste melts rapidly and is extruded into strips through the output end of the processing cylinder. These strips are then conveyed through a conveying pipe into a cooling box for cooling. The device utilizes a spiral cooling pipe, a liquid storage tank, and a liquid pump to rapidly cool and solidify the strips. Finally, a cutting mechanism cuts them into standard-sized small particles, completing the recycling and regeneration process. The scientifically designed equipment and optimized process significantly reduce recycling costs and enhance the economic benefits for enterprises. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 4This embodiment of a conductive plastic masterbatch recycling and reprocessing device includes a base plate 1 and a processing cylinder 2. An annular heating plate 3 is installed on the inner wall of the processing cylinder 2. The annular heating plate 3 is made of ceramic fiber material, which has good heat insulation and durability. A servo motor 4 is fixedly connected to one side of the processing cylinder 2. A screw conveyor 5 is fixedly connected to the output shaft end of the servo motor 4. The screw conveyor 5 is located inside the processing cylinder 2 and is made of high-quality stainless steel to ensure that it is not easily deformed during long-term operation. When the servo motor 4 starts, it drives the screw conveyor 5 to rotate. The rotation of the screw conveyor 5 can evenly transport the conductive plastic waste to be processed. The activation of the annular heating plate 3 can evenly heat and melt the conductive plastic waste during the transportation process. The output end of the processing cylinder 2 is connected to a conveying pipe 6. The melted conductive plastic waste is extruded through the output end of the processing cylinder 2 into the conveying pipe 6 for transport. Since the conveying pipe 6 is a straight pipe, the conductive plastic waste is transported in a strip-like form. A cooling box 7 is fixedly connected to the other side of the processing cylinder 2. The cooling box 7 is fitted outside the conveying pipe 6. A spiral cooling pipe 8 is installed inside the cooling box 7 and is fitted outside the conveying pipe 6. A liquid storage tank 9 is fixedly connected to the upper surface of the base plate 1. Two liquid pumps 10 are installed on the top of the liquid storage tank 9. The tops of the two liquid pumps 10 are connected to the two bottom ends of the spiral cooling pipe 8, respectively. When the two liquid pumps 10 are started, the coolant in the liquid storage tank 9 can be circulated through the spiral cooling pipe 8, thus cooling and solidifying the strip-like material in the conveying pipe 6 to form a long strip-shaped material with a certain strength.

[0032] Please see Figure 2 , Figure 3 and Figure 4 The cooling box 7 is equipped with a cutting mechanism 11 on its exterior. The cutting mechanism 11 includes a cylinder 1101 fixedly connected to the upper surface of the cooling box 7. A cutting blade 1102 is fixedly connected to the output end of the cylinder 1101. The cutting blade 1102 is located above the conveying pipe 6. The cutting blade 1102 is made of hard alloy steel, which is sharp and durable and can effectively cut hard plastic products. By setting the cutting mechanism 11, the long strip material after cooling can be cut into small particles of standard size. A collection box 12 is fixedly connected to the upper surface of the bottom plate 1. The collection box 12 is located below the conveying pipe 6. By setting the collection box 12, the formed recycled products can be collected, which is convenient for operation. A controller 13 is installed on the outer surface of the processing cylinder 2. The annular heating plate 3, servo motor 4, liquid pump 10 and cylinder 1101 are all electrically connected to the controller 13. By setting the controller 13, the electrical components in the device can be easily controlled to work, which simplifies the operation.

[0033] Please see Figure 1 , Figure 2 and Figure 3Support columns 14 are fixedly connected to the four corners of the bottom surface of the base plate 1. The support columns 14 make the device more stable on the contact surface. A hopper 15 is installed at the top of the processing cylinder 2. The output end of the hopper 15 is connected to the inside of the processing cylinder 2. The conductive plastic waste that needs to be recycled can be put into the processing cylinder 2 through the hopper 15, which facilitates the recycling and regeneration of conductive plastic waste. An inlet 16 is installed on the outer surface of the liquid storage tank 9. The output end of the inlet 16 is connected to the inside of the liquid storage tank 9. The inlet 16 makes it easy to add an appropriate amount of coolant to the liquid storage tank 9. A drain port 17 is installed on the bottom surface of the liquid storage tank 9. The input end of the drain port 17 is connected to the inside of the liquid storage tank 9. The drain port 17 allows the coolant in the liquid storage tank 9 to be discharged to the outside, which facilitates the replacement of the coolant in the liquid storage tank 9.

[0034] In this embodiment, a conductive plastic masterbatch recycling and reprocessing device significantly improves the recycling rate of conductive plastic masterbatch, enabling more waste materials to be transformed back into valuable products and reducing resource waste. The conductive plastic waste to be processed is fed into the processing cylinder 2. By activating the annular heating plate 3 and servo motor 4, the waste is gradually heated and stably conveyed. It rapidly melts at high temperature and is extruded into strips through the output end of the processing cylinder 2. These strips are then transported to the cooling box 7 via the conveying pipe 6 for cooling. The spiral cooling pipe 8, liquid storage tank 9, and liquid pump 10 rapidly cool and solidify the strips. Finally, the material is cut into standard-sized small particles by the cutting mechanism 11, completing the recycling process. Through scientific and reasonable equipment design and process optimization, the cost of recycling is significantly reduced, enhancing the economic benefits for enterprises.

[0035] The working principle of the above embodiment is as follows: First, the staff puts the sorted conductive plastic waste into the hopper 15. After starting the equipment, the waste is evenly conveyed by the screw conveyor 5. During the conveying process, the waste is heated by the annular heating plate 3. At this stage, the waste gradually softens under the influence of increasing heat, avoiding the problem of local overheating that may be caused by direct high temperature. Then, the softened waste is squeezed into the conveying pipe 6 through the output end of the processing cylinder 2, forming continuous strips that are conveyed in the conveying pipe 6. Then, the strips are conveyed to the cooling box 7 through the conveying pipe 6 to enter the cooling process. At this time, the two started liquid pumps 10 can circulate the coolant in the storage tank 9 through the spiral cooling pipe 8. The spiral cooling pipe 8 is sleeved on the outside of the conveying pipe 6, which can cool the strips inside the conveying pipe 6 and accelerate hardening, ensuring shape stability. After that, the cylinder 1101 is started to make the cutting blade 1102 move up and down to precisely cut these strips to form masterbatch of uniform specifications. Finally, the finished masterbatch automatically falls into the collection box 12, waiting to be packaged and shipped.
