[0002] Thermoplastic plastics refer to materials that can be shaped at high temperatures, have good hardness and stability after cooling, and can repeat this process. They are also a raw material for common plastic products nowadays. According to needs, they will be produced into different products, which requires mixing and processing of multiple materials, and it is also one of the main means of plastic product production.
[0003] Currently, for mixing, basically multiple plastics are stirred and then uniformly injected into a hot melt device for hot melting. And the current hot melt device has only one main heat supply point, and the heat source here radiates heat to the surrounding to hot melt the plastics. This method has low efficiency and uneven heating. Therefore, a hot melt mixer for thermoplastic plastics is proposed. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The present utility model will be further described below with reference to the drawings.
[0016] Please refer to Figures 1-4 , a hot melt mixer for thermoplastic plastics of the present utility model includes a processing tank body 1. An inner tank is fixedly connected inside the processing tank body 1. A heating tank 9 is provided between the processing tank body 1 and the inner tank. An electric heating coil 10 is detachably and inlaid in the heating tank 9. The electric heating coil 10 is of a spiral structure and is evenly attached and distributed on the outer wall of the inner tank. A wire groove is penetrated and opened on the side wall of the processing tank body 1 near the bottom end, and a wire is inserted in the wire groove. The heating tank 9 is connected to a power supply through the wire. A sealing ring 11 is detachably connected to the bottom opening of the heating tank 9.
[0017] The technical effect of this solution is as follows: The electric heating coil 10 is installed in the heating tank 9, and the heating tank 9 is electrified through an electric wire to raise the temperature for heating. Since the electric heating coil 10 is in a spiral state, the heat will be evenly distributed along the electric heating coil 10 on the side wall of the inner tank, thereby increasing the interior of the inner tank, and uniformly heating and melting the particles inside the inner tank, so as to improve the efficiency of hot melting and avoid the quality problem of the hot-melt material caused by incomplete melting, which results in fine particles in the hot-melt material. At the same time, because the sealing ring 11 is detachably connected, it is convenient to take out the electric heating coil 10 from the heating tank 9 for maintenance and replacement.
[0018] A cover plate 2 is detachably connected to the top side wall of the processing tank body 1. A motor 3 is detachably connected to the middle of the top side wall of the cover plate 2 away from the processing tank body 1. A stirring column 7 is arranged inside the inner tank. Support arms 8 are evenly and fixedly connected to the outer wall of the stirring column 7. A scraper 12 is fixedly connected to one end of each support arm 8 away from the stirring column 7. The scraper 12 is an inclined conical structure. The side of the scraper 12 away from the support arm 8 is attached to the inner wall of the inner tank. The top end of the stirring column 7 is rotatably connected to the bottom side wall of the cover plate 2. The output end of the motor 3 passes through the cover plate 2 and is detachably connected to the top end of the stirring column 7. One fixing plate 4 is fixedly connected to the outer peripheral walls of both sides of the processing tank body 1 near the bottom end and away from each other. A support column 5 is fixedly connected to the middle of the bottom side wall of each fixing plate 4. A discharge plate 6 is arranged at the bottom of the processing tank body 1. The discharge plate 6 is a conical structure and is fixedly connected to the bottom side wall of the inner tank. The discharge plate 6 is communicated with the inside of the inner tank.
[0019] The technical effect of this solution is as follows: Since the hot-melted material has adhesiveness, residues are inevitably left on the inner wall of the inner tank during the discharge process of processing. To avoid affecting subsequent processing, the residues need to be processed. However, the current processing methods are not convenient enough and will cause waste. Therefore, support arms 8 and scrapers 12 are provided. As the stirring column 7 drives the support arms 8 and the scrapers 12 to rotate, the residues adhering to the inner wall of the inner tank can be scraped and cleaned, improving the overall processing efficiency and avoiding waste of resources.
[0020] Specifically, when the utility model is in use, plastic particles are put into the inner container, and then the electric heating coil 10 is powered on. The inner container is heated by electromagnetism to melt the plastic particles inside the inner container. Since the electric heating coil 10 is spiral, the inner container can be heated evenly, so that the plastic particles can be heated and melted evenly. This can also improve the efficiency of melting the plastic particles and avoid the problem of the quality of the melted material caused by particles during discharging. To prevent residues from adhering to the inner wall of the inner container and avoid waste of resources due to residual materials, a scraper 12 is fixed at one end of the support arm 8, and the scraper 12 is attached to the inner wall of the inner container. The scraper 12 is driven to rotate by the stirring column 7 to scrape off the residues on the inner wall of the inner container, eliminating the residues and avoiding waste of resources caused by this. The support arm 8 and the scraper 12 are connected to the stirring column 7 in a multi-layer spiral shape, which can clean the residues layer by layer, improving the cleaning effect and efficiency. Finally, the melted material is discharged from the discharge plate 6.
[0021] The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the utility model.
[0022] Other parts not detailed in the utility model belong to the prior art and will not be elaborated here.
[0023] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
