[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-5 The melting device for producing engineering plastics shown includes a melting chamber 5 and a drive motor 3 installed on the left side of the melting chamber 5;

[0027] A heating jacket 10 is provided on the circular outer wall of the melting chamber 5 to provide heat;

[0028] A drive rod 4, which is inserted into the melting chamber 5, is fixedly connected to the outer wall of the right end of the drive motor 3.

[0029] The drive rod 4 has a spiral blade 9 on its circular outer wall to guide the material movement. The upper circular outer wall of the melting chamber 5 has a feeding port 6. Raw materials are added to the inside of the melting chamber 5. The lower outer wall of the melting chamber 5 is located near the right side with a discharge pipe 13. The heating jacket 10 provides continuous heat to the melting chamber 5, so that the plastic particles reach a molten state inside the melting chamber 5. The drive motor 3 drives the spiral blade 9 to continuously stir and push through the rotation of the drive rod 4. Through the feeding port 6, the operator can add raw materials in real time to ensure the flow of raw materials and the uniform distribution of heat in the melting chamber 5. After the material melts, it is pushed by the spiral blade 9 and discharged smoothly through the discharge pipe 13 to enter the subsequent processing stage.

[0030] The inside of the feeding port 6 is equipped with comb teeth a15, and comb teeth b18 are provided on both the left and right sides of the comb teeth a15. The upper outer wall of the two comb teeth b18 is fixedly connected with the dispersing strip 16. When the raw material enters the melting chamber 5 through the feeding port 6, the comb teeth a15 will first perform preliminary combing and guidance on the raw material to ensure that the raw material can smoothly enter the melting area. The comb teeth b18 rotate under the drive of the drive rod 4. Through its unique shape, it can enhance the guidance of the material. The design of the dispersing strip 16 allows it to move synchronously with the comb teeth b18 when they rotate. By tapping, it loosens and clears the plastic particles adhering to the inner wall of the feeding port 6.

[0031] like Figure 3 As shown, movable chambers 19 are fixedly connected to the outer walls of both ends of the feeding port 6. A transmission rod 17 is provided between the two movable chambers 19 to limit the position of comb teeth a15 and b18. A fixed wheel a21 is fixedly connected to the circular outer wall of the transmission rod 17. A fixed wheel b23 is fixedly connected to the circular outer wall of the drive rod 4. A transmission belt 22 is provided between the fixed wheel a21 and the fixed wheel b23 to transmit the power of the drive rod 4 to the transmission rod 17. A positioning shaft b20 is fixedly connected to the inner wall of the right end of the movable chamber 19 to limit the position of the transmission rod 17.

[0032] The drive motor 3 rotates via the drive rod 4, which in turn drives the fixed wheel b23 to rotate. The rotational power is transmitted to the fixed wheel a21 via the transmission belt 22, and then rotates via the transmission rod 17, thereby driving the comb teeth a15 and b18 to rotate synchronously.

[0033] like Figure 3 As shown, the two comb teeth b18 are inclined, and the two dispersion strips 16 are made of hard plastic.

[0034] When comb teeth a15 and b18 rotate, the inclined comb teeth b18 guide and comb the raw material passing through the feed port 6, and the beating action of the dispersing strip 16 helps to loosen and disperse the material accumulated on the inner wall of the feed port 6, ensuring that the material flows into the melting chamber 5 continuously.

[0035] like Figure 2 As shown, a heat insulation sleeve 7 is fixedly connected to the circular outer wall of the heating jacket 10 to prevent the temperature from spreading outward. A fixed end 12 is fixedly connected to the outer wall of the right end of the heat insulation sleeve 7. A positioning shaft a11 is fixedly connected to the inner wall of the right end of the fixed end 12 to limit the position of the drive rod 4. A flange interface 14 is provided on the outer wall of the lower end of the discharge pipe 13.

[0036] Heating jacket 10 provides the necessary heat, heat insulation jacket 7 effectively isolates the interference of external temperature, and keeps the temperature in melting chamber 5 stable. Fixed end 12 and positioning shaft a11 ensure the stable position of drive rod 4 and prevent the drive rod 4 from shifting due to vibration or lateral force. Through flange interface 14, discharge pipe 13 can be easily connected to molding equipment to ensure smooth discharge of molten material and maintain production continuity.

[0037] like Figure 1 As shown, a base 1 is provided on the lower side of the drive motor 3. A support seat a2 is fixedly connected between the upper outer wall of the base 1 and the drive motor 3 to limit the position of the drive motor 3. A support seat b8 is fixedly connected between the base 1 and the heat insulation sleeve 7 to limit the position of the heat insulation sleeve 7.

[0038] The base 1 and its connected support a2 and support b8 provide stable support for the drive motor 3 and the heat insulation sleeve 7, so that the components will not be displaced due to vibration or other external impacts during the operation of the entire system.

[0039] The implementation principle of this embodiment is as follows: The heating jacket 10 provides continuous heat to the melting chamber 5, so that the plastic particles reach a molten state inside the melting chamber 5. The drive motor 3 drives the spiral blade 9 to continuously stir and push through the rotation of the drive rod 4. Through the feeding port 6, the operator can add raw materials in real time to ensure the flow of raw materials and the uniform distribution of heat in the melting chamber 5. After the material melts, it is pushed by the spiral blade 9 and discharged smoothly through the discharge pipe 13 to enter the subsequent processing stage. When the raw material enters the melting chamber 5 through the feeding port 6, the comb teeth a15 will first perform preliminary combing and guidance of the raw material to ensure that the raw material can smoothly enter the melting area. The comb teeth b18 rotate under the drive rod 4. Through its unique shape, it can enhance the guidance of the material. The design of the dispersing strip 16 allows it to move synchronously with the comb teeth b18 when they rotate. Through the tapping method, it loosens and clears the plastic particles adhering to the inner wall of the feeding port 6.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
