[0028] Please refer to Figures 1 to 5 , the present utility model discloses a smelting mechanism 10, which includes a screw component 100 and a heating component 200. The heating component 200 is disposed on the side surface of the screw component 100, so that the heating component 200 can heat the screw component 100 to realize smelting of the material transported inside the screw component 100. Among them, the screw component 100 includes a screw structure 110 for mixing and conveying materials. Correspondingly, the heating component 200 includes a plurality of heating structures 210. The plurality of heating structures 210 are sequentially arranged on the outer surface of the screw structure 110 along the length extension direction of the screw structure 110. Thus, when the screw structure 110 mixes and conveys materials, the plurality of heating structures 210 output heat from the outside of the screw structure 110 to the inside of the screw structure 110 to heat the mixed and conveyed materials to a preset smelting temperature. In this way, the plurality of heating structures 210 cooperate with each other to stably heat the whole screw structure 110, so that the materials can maintain the consistency of the smelting temperature during the mixing and conveying process. Compared with the traditional integrated basic machine of a screw and a smelting mechanism, the smelting mechanism 10 of the present utility model arranges a plurality of heating structures 210 in a segmented manner outside the screw structure 110, without setting an embedded air-cooling structure or a water-cooling structure in the screw. Therefore, the maintenance and repair difficulty of the screw can be greatly reduced, and the maintenance cost of the screw can be saved. At the same time, the plurality of heating structures 210 can work independently. By monitoring each heating structure 210 separately, flexible adjustment can be made according to the actual smelting conditions, so as to effectively improve the production flexibility and adaptability of the smelting mechanism 10, and further enhance the stability of the production process.

[0029] Furthermore, each heating structure 210 includes a shell 211 and a heating unit 212. The heating unit 212 is sleeved on the corresponding installation position on the side surface of the screw structure 110. The shell 211 is sleeved on the outside of the heating unit 212 relative to the screw structure 110, so that the heating unit 212 can heat the corresponding position of the screw structure 110, and the shell 211 can isolate the heating unit 212 from the external environment, thereby limiting the heat exchange between the heating unit 212 and the external environment, thereby improving the heating efficiency of the heating unit 212 on the screw. In this embodiment, the heating unit 212 is configured as a heating plate, which is wrapped around the corresponding installation position on the side surface of the screw structure 110, so that the heating plate can evenly heat the corresponding position of the screw structure 110.

[0030] Furthermore, each heating structure 210 also includes a heat dissipation unit 213, which is arranged on the side wall of the shell 211, and the output end of the heat dissipation unit 213 is connected to the inside of the shell 211. When the smelting mechanism 10 completes smelting, it is necessary to dissipate heat and cool the screw structure 110 and the heating unit 212, and the output end of the heat dissipation unit 213 outputs an airflow to cool the corresponding heating unit 212 and the screw structure 110. In this embodiment, the heat dissipation unit 213 is configured as a heat dissipation fan, and the output end of the heat dissipation fan is connected to the inside of the shell 211, so that the normal temperature airflow output by the heat dissipation fan can be blown to the heating unit 212 through the shell 211, and then the corresponding positions of the heating unit 212 and the screw structure 110 wrapped therein are cooled by air.

[0031] Furthermore, the heat dissipation unit 213 is arranged at the bottom of the shell 211, and correspondingly, a plurality of ventilation holes a are arranged at the top of the shell 211; the output end of the heat dissipation unit 213 is connected to the inside of the shell 211 from the bottom of the shell 211; the plurality of ventilation holes a penetrate the side wall at the top of the shell 211, so that each ventilation hole a connects the inside of the shell 211 with the external environment. When the heat dissipation unit 213 performs air cooling and heat dissipation on the corresponding positions of the heating unit 212 and the screw structure 110, the cooling airflow is blown into the shell 211 from the bottom of the shell 211, and after being fully contacted and heat-exchanged with the heating unit 212 and the screw structure 110 inside, it is blown out to the outside of the shell 211 through the plurality of ventilation holes a, thereby greatly improving the heat dissipation efficiency of the heating structure 210 and the screw structure 110.

[0032] Further, the screw assembly 100 includes a frame 110 and a drive assembly 120. The screw structure 110 includes a conveying pipe 111 and a screw 112. The drive assembly 120 and the conveying pipe 111 are installed on the frame 110, and the screw 112 is installed inside the conveying pipe 111. The output end of the drive assembly 120 is drivingly connected to one end of the screw 112. Thus, the drive assembly 120 can drive the screw 112 to rotate and convey materials in cooperation with the conveying pipe 111. Specifically, a number of heating structures 210 are sequentially arranged on the outer surface of the side wall of the conveying pipe 111 along the length extension direction of the conveying pipe 111, so that each heating structure 210 can heat up the conveying pipe 111 and the materials conveyed therein, thereby realizing the melting and processing of the materials.

[0033] Further, the drive assembly 120 includes a motor 121, a coupling 122, and a speed reducer 123. The motor 121 and the speed reducer 123 are installed on the top of the frame 110. The output end of the motor 121 is drivingly connected to the input end of the speed reducer 123 through the coupling 122, and the output end of the speed reducer 123 is drivingly connected to the screw 112. Thus, the motor 121 and the speed reducer 123 can stably drive the screw 112 to rotate steadily at a preset speed. The speed reducer 123 can effectively increase the torque of the screw 112, thereby increasing the conveying capacity of the screw 112 for the materials.

[0034] Further, the screw assembly 100 further includes a feed hopper 130. The feed hopper 130 is arranged at one end of the conveying pipe 111, and the feed hopper 130 communicates with the inside of the conveying pipe 111, so that the materials to be melted can be fed into the conveying pipe 111 through the feed hopper 130 for conveying and melting and processing.

[0035] In summary, the heating assembly of the melting mechanism disclosed by the present utility model includes a plurality of heating structures, and the plurality of heating structures are sequentially arranged on the outer surface of the screw structure along the length extension direction of the screw structure. Thus, when the screw structure mixes and conveys materials, the plurality of heating structures output heat from the outside of the screw structure to the inside of the screw structure to heat the materials in the mixed conveyance to a preset melting temperature. In this way, the plurality of heating structures cooperate with each other to stably heat the whole screw structure, so that the materials can maintain the consistency of the melting temperature during the mixing and conveying processes. Compared with the traditional basic machine with an integrated screw and melting mechanism, the melting mechanism of the present utility model arranges the plurality of heating structures in a segmented manner on the outside of the screw structure, without setting an embedded air-cooling structure or water-cooling structure in the screw. In this way, the maintenance and repair difficulty of the screw can be greatly reduced, the maintenance cost of the screw can be saved, and at the same time, the plurality of heating structures can work independently. By monitoring each heating structure separately, flexible adjustment can be made according to the actual melting condition, so as to effectively improve the production flexibility and adaptability of the melting mechanism, and further enhance the stability of the production process.

[0036] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0037] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
