[0002] Polyester chips are a type of polyester raw material produced through polymerization. They are mainly used in containers, packaging materials, films, sheets, and engineering plastics. Existing polyester chips are usually melted in a closed system, making it impossible to observe the melting process and progress, resulting in poor performance.

[0003] A search revealed that prior art CN219543734U discloses a polyester chip melting device, including a workbench. A box is located on the top left side of the workbench, and a lid is located on the top of the box. A water tank is fixedly connected to the rear side of the lid, and a water outlet pipe is connected to the right side of the water tank. The end of the water outlet pipe is connected to the lid. A servo motor is fixedly connected to the middle of the lid, and the output end of the servo motor passes through the lid and is fixedly connected to a rotating rod. In this invention, a high-pressure nozzle sprays water to wash the raw material, while a vibration motor is activated to vibrate the raw material, increasing the cleaning efficiency and preventing a decrease in the quality of the melted polyester chips. The polyester chips are placed in a receiving tray, and an air pump extracts heat while simultaneously spraying heat onto the polyester chips through an air outlet pipe, thereby melting the polyester chips. The melting process and progress of the polyester chips can be observed.

[0004] The device pours the cleaned polyester chips from the filter box onto a slanted tray, where the polyester chips come into contact with the outside environment again and become contaminated with new dust and dirt, which will reduce the quality of the processed product. Utility Model Content

In addition, the circuits, electronic components, and modules involved in this utility model are all prior art, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve the improvement of software and methods. In the idle areas of this device, all the aforementioned electrical components, referring to power elements, electrical devices, and compatible PLCs and power supplies, are connected via wires. The specific connection methods should refer to the working principle described below, where the electrical connections are completed according to the sequential operation of each component. The detailed connection methods are well-known in the field; the following mainly describes the working principle and process, without further explanation of electrical control. The PLC is installed in the control cabinet, which mainly consists of the cabinet body and electrical components. The cabinet contains the PLC, AC contactor, circuit breaker, thermal relay, intermediate relay, and fuse. A control panel that works with the control cabinet is located on the right side of the melting tank 101. The top of the control panel is a temperature controller used to control the heating ring 116 and the heating rod 117. When the temperature reaches the detection value, the temperature controller stops the heating ring 116 and the heating rod 117; when the temperature is below the set value, the temperature controller keeps the heating ring 116 and the heating rod 117 running. The temperature controller can be the device disclosed in existing technology CN211762764U. The heating ring 116 has a safe distance from the tank wall. The disc at the bottom of the support foot of the melting tank 101 is provided with mounting holes.

[0020] The first filter screen 106 is installed on the side wall of the hopper 104. The sealing cover 107 is installed on the hopper 104 and located outside the first filter screen 106. A dust suction pipe 115 is connected to the sealing cover 107. The working part of the dust suction pipe 115 extends into the hopper 104 without interfering with the stirring member 114, and its suction hole diameter is smaller than the diameter of the polyester chip raw material. The guide pipe seat 108 is installed outside the left outlet of the sealing cover 107, and the electric valve 109 is installed on the guide pipe. The suction fan 110 is installed at the left outlet of the seat 108, the connecting pipe 111 is installed at the air outlet side of the suction fan 110, the collecting pipe 112 is threadedly connected to the connecting pipe 111 and is located at the air outlet side of the connecting pipe 111, the second filter screen 113 is fixed on the air outlet of the collecting pipe 112, the stirring component 114 is arranged in the hopper 104, the heating component is arranged on the melting tank 101, and the mixing component is arranged in the melting tank 101. The inner side of the first filter screen 106 is an arc-shaped structure adapted to the inner surface of the hopper 104. The fixing frame is fixed with bolts. The sealing cover 107 is fixed with bolts. The two discs of the dust removal pipe 115 are fixed with bolts respectively. The rectangular plate of the guide seat 108 is fixed with bolts for sealing the port of the sealing cover 107 and guiding ventilation. The flanges on the electric valve 109, the suction fan 110, and the connecting pipe 111 are all connected to the mating parts by screws and nuts. The air outlet side of the connecting pipe 111 has an external thread end pipe structure, which facilitates the installation of the collection pipe 112. The second filter screen 113 is fixed with bolts for ventilation and to block dust and impurities inside the collection pipe 112 for collection. The stirring component 114 consists of a stirring motor and a stirring frame. When the stirring motor is activated, it can drive the stirring frame to rotate to realize the stirring of raw materials. The heating component and the mixing component cooperate to realize the melting treatment of raw materials. The electric valve 109 and the suction fan 110 can be activated or stopped simultaneously.

[0021] Secondly, multiple heating rings 116 are installed inside the melting tank 101 and arranged vertically at intervals; multiple heating rods 117 are installed at the bottom of the melting tank 101 and arranged in a ring at intervals. The heating rings 116 can be products disclosed in prior art CN220008441U, and the corresponding fixing method also directly adopts prior art. The heating rods 117, like the heating rings 116, are electrically heated, and the fixing plate is fixed by bolts. A temperature sensor 121 is also installed on the melting tank 101 for internal temperature detection.

[0022] Then, the mixing motor 118 is fixed to the top sealing plate of the melting tank 101; the mixing frame 119 is connected to the output shaft of the mixing motor 118 via a coupling. The mixing motor 118 is fixed with bolts, and the mixing frame 119 is mounted on its output shaft via a coupling.

[0023] Finally, a third filter 120 is installed on the outside of the vent on the sealing plate at the top of the melting tank 101. This structure facilitates the discharge of hot gas during heating and prevents dust or impurities from falling into the interior through the third filter 120.

[0024] When using this invention to improve the melt quality of the product, the raw materials are first fed into the hopper 104 during processing. Then, the stirring component 114 is turned on, and the stirring component 114 stirs the raw materials. During the stirring process, dust and fine impurities in the polyester chips are separated from the polyester chips. At the same time, the suction fan 110 is started. The suction fan 110 generates suction, which draws the dust and fine impurities into the sealing cover 107 through the mesh of the first filter screen 106. Meanwhile, some dust or impurities are introduced through the dust removal pipe 115. Inside the sealing cover 107, dust or impurities are moved to the connecting pipe 111 and discharged under the action of the electric valve 109 and the suction fan 110. Finally, they are guided into the collection pipe 112 for centralized collection and treatment. After a certain period of dust removal, the electric valve 109 is closed, the suction fan 110 is stopped, and the material guide valve 102 is opened. The raw material falls directly into the melting tank 101 for melting and processing without contact with the outside world, which can greatly ensure the purity of the raw material after melting and thus effectively improve the quality of the melted product.
