Description

Technical Field

[0001] This utility model relates to the field of waste plastic recycling technology, specifically to a waste plastic recycling and reuse device. Background Technology

[0002] Plastics, a common material in daily life, play a vital role in food packaging, agriculture, the electrical appliance industry, and the chemical industry. Plastics are materials made primarily of resin, with plasticizers, fillers, lubricants, colorants, and other additives as auxiliary components, which can flow and be molded during processing. Plastics are synthetic polymer compounds that can be freely modified into various shapes and forms.

[0003] Currently, there are various types of plastic-containing materials commonly found in daily life. Traditional methods of plastic disposal mainly involve landfilling or incineration, which not only wastes valuable resources but also causes serious environmental pollution. Therefore, a waste plastic recycling and reuse device is proposed. Utility Model Content

[0004] The present invention aims to solve the above-mentioned problems by providing a device for recycling and reusing waste plastics.

[0005] This utility model is achieved through the following technical solution: a waste plastic recycling and reuse device, characterized in that it includes a crusher, a screw conveyor at the discharge port of the crusher, a melting machine at the discharge port of the screw conveyor, a pressure pump at the outlet of the melting machine, a molding die at the outlet of the pressure pump, a cooling box at the discharge port of the molding die, an automatic cutting device at the discharge port of the cooling box, the automatic cutting device including a cutting blade installed at the discharge port and an electric push rod for controlling the movement of the cutting blade, and a feeding platform below the cutting blade.

[0006] Furthermore, the melting machine is equipped with a temperature sensor one, and the cooling box is equipped with a temperature sensor two.

[0007] Furthermore, the discharge pipe of the melting machine is also equipped with a valve and a flow sensor.

[0008] The beneficial effects of this utility model are: this utility model uses a crusher to crush waste plastics of different sizes into granules, and then uses a melting machine to heat them, thereby reshaping the plastics, so that people can recycle and reuse them.

[0009] This invention is simple to operate and facilitates the recycling and processing of various plastic wastes. After processing, the wastes are easy to reuse, effectively saving resources and avoiding environmental pollution. Attached Figure Description

[0011] In the attached diagram, 1 is a crusher, 2 is a screw conveyor, 3 is a melting machine, 4 is a temperature sensor 1, 5 is a valve, 6 is a flow sensor, 7 is a pressure pump, 8 is a forming mold, 9 is a cooling box, 10 is a temperature sensor 2, 11 is an electric push rod, 12 is a cutting blade, and 13 is a feeding platform. Detailed Implementation

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further explained below in conjunction with the embodiments.

[0013] like Figure 1 As shown, a waste plastic recycling and reuse device is characterized by comprising a crusher 1, which crushes waste plastics of varying sizes into granules. A screw conveyor 2 is installed at the outlet of the crusher 1, which transports the granular plastic to a melting machine 3. The melting machine 3 heats and melts the plastic into a fluid. A pressure pump 7 is installed at the outlet of the melting machine 3, and the outlet of the pressure pump 7 is connected to a molding die 8. The pressure pump 7 transports the fluid plastic to the molding die 8 for molding. A cooling box 9 is installed at the outlet of the molding die 8, which cools and solidifies the molded finished plastic. An automatic cutting device is installed at the outlet of the cooling box 9, which cuts the solidified finished plastic, such as plastic tubes, to a uniform length. The automatic cutting device includes a cutting blade 12 installed at the outlet and an electric push rod 11 controlling the movement of the cutting blade 12. A feeding platform 3 is located below the cutting blade 12.

[0014] To facilitate temperature monitoring within the melting machine 3, a temperature sensor 4 is installed inside the melting machine 3. Similarly, to facilitate temperature monitoring within the cooling chamber 9, a temperature sensor 10 is installed inside the cooling chamber 9. A valve 5 and a flow sensor 6 are also installed on the discharge pipe of the melting machine 3. The temperature signals from temperature sensors 4 and 10 are transmitted to the controller. The controller determines whether the temperature deviates from the set value; if it does, it adjusts the work done by the melting machine 3 and the cooling chamber 9.

[0015] In use, waste plastic is put into the hopper of crusher 1 for crushing. The crushed plastic particles are conveyed to the melting machine 3 by screw conveyor 2 for melting. The melted plastic is conveyed to the molding die 8 by pressure pump 7 for extrusion molding. The molded die is conveyed to the cooling box 9 for cooling. The cooled die is cut into plastic materials of uniform length by cutting blade 12 at the outlet of cooling box 9 and falls onto the unloading platform 3.

[0016] Apart from the technical features described in the specification, all other technical features are known to those skilled in the art.
