After the processing and preparation, it is discharged through the discharge port 105. The following is also provided on the main body 100 of the mixing device for preparation:

[0024] A heat storage and insulation mechanism, and this heat storage and insulation mechanism includes a heat storage protection component arranged on the outer surface of the mixing tank 101 for preparation, and a heat insulation component is arranged on the inner surface of the heat storage protection component. When the main body 100 of the mixing device for preparation is used for processing, mixing and treatment in cold seasons, the heat storage and insulation mechanism can heat the outer surface of the mixing tank 101 for a long time, heat the interior faster, quickly heat for processing and mixing, and improve the heat preservation, mixing and preparation effect of the main body 100 of the mixing device for preparation when preparing and mixing polycarbonate-based polyurethane thermoplastic elastomer materials.

[0025] In order to facilitate heat storage protection of the outer surface of the mixing tank 101 for preparation through the heat storage protection component, slow heat dissipation is easy, and internal heating treatment is fast. In this embodiment, preferably, the heat storage protection component includes an outer protection cylinder 1011 arranged on the outer surface of the mixing tank 101 for preparation. Mounting bolts 1015 are rotated at the edge positions of both ends of the outer protection cylinder 1011. The outer protection cylinder 1011 is fixedly installed on the outer surface of the mixing tank 101 for preparation through the mounting bolts 1015, which is convenient for installation and use. The outer surface of the outer protection cylinder 1011 and the outer surface of the mixing tank 101 for preparation are fixedly installed through the mounting bolts 1015. A heat preservation and heat storage groove 1013 is formed at the connection between the inner surface of the outer protection cylinder 1011 and the outer surface of the mixing tank 101 for preparation. After the fixed installation, it is convenient to store heat and perform heat preservation treatment inside the heat preservation and heat storage groove 1013 during heating in cold seasons, with slow heat dissipation, enabling rapid heating of the interior of the mixing tank 101 for preparation.

[0026] In order to facilitate heat preservation inside the heat storage tank 1013 through the heat preservation component during heat storage, prevent rapid heat dissipation, and enable the main body 100 of the preparation mixing device to use accelerated heating treatment. In this embodiment, preferably, the heat preservation component includes heat preservation cotton 1012 disposed on the inner surface of the outer protection cylinder 1011.

After the outer protection cylinder 1011 is fixed, it protects the internal heat preservation during heat storage and enables rapid heating preparation treatment.

[0027] A stability control mechanism, and this stability control mechanism includes a stability control component disposed at the bottom end of the rotating shaft 106 inside the preparation mixing tank 101. A rotation control component is provided at the top end of the stability control component, and an auxiliary stirring component is provided on the side of the stability control component. When the main body 100 of the preparation mixing device is processing and preparing the mixture, the stability control mechanism can stably control the rotation and stirring during the rotation of the rotating shaft 106 and the stirrer 107, and at the same time facilitate uniform stirring, improving the stability of the rotating shaft 106 and the uniformity of stirring when the main body 100 of the preparation mixing device is processing and preparing the polycarbonate-based polyurethane thermoplastic elastomer material.

[0028] In order to facilitate the stable rotation and preparation mixing process of the rotating shaft 106 and the stirrer 107 through the stability control component, in this embodiment, preferably, the stability control component includes a fixing ring 1061 fixedly installed at the bottom end of the rotating shaft 106 through bolts. A support control frame 1062 is fixedly welded on the surface of the fixing ring 1061 inside the preparation mixing tank 101. The support control frame 1062 is fixed to the bottom end of the rotating shaft 106 through the fixing ring 1061, facilitating the stable rotation of the support control frame 1062 driven by the rotation of the rotating shaft 106, so as to stably control the rotation and stirring of the rotating shaft 106 and the stirrer 107 through the support control frame 1062.

[0029] In order to facilitate the stable control of the top end during the rotation of the support control frame 1062 through the rotation control component, in this embodiment, preferably, the rotation control component includes a rotation groove 1064 opened at the top end of the preparation mixing tank 101. Two rotation blocks 1065 are provided inside the rotation groove 1064, and the rotation blocks 1065 are rotatably connected to the inside of the rotation groove 1064. The top end of the support control frame 1062 is fixedly welded to the bottom end of the rotation block 1065. When the support control frame 1062 rotates, it drives the rotation block 1065 to rotate inside the rotation groove 1064, thereby stably rotating the top end of the support control frame 1062 and the inner top end of the preparation mixing tank 101.

[0030] In order to facilitate uniform stirring of the inner surface of the preparation mixing tank 101 by following the rotation of the support control frame 1062 through the auxiliary stirring assembly, in this embodiment, preferably, the auxiliary stirring assembly includes stirring rods 1063 welded at equal intervals on one side of the support control frame 1062, and the stirring rods 1063 on both sides are symmetrically arranged. When the support control frame 1062 rotates and is controlled, the stirring rods 1063 can be driven to rotate at the edge of the inner surface of the preparation mixing tank 101 for uniform mixing and preparation.

[0031] The working principle and usage process of the present utility model: For this polycarbonate-based polyurethane thermoplastic elastomer material preparation and mixing device, during use, the preparation and mixing device main body 100 is stably placed at the processing and production position by the support legs 104 contacting the ground. After the preparation and mixing device main body 100 is stably placed, the heating element 108 heats up, and the raw materials are injected into the interior of the preparation mixing tank 101 through the inlet 102. The motor 103 operates to drive the rotating shaft 106 and the stirrer 107 to rotate, facilitating the stirrer 107 to rotate for mixing and processing the raw materials inside. After the preparation and processing, the materials are discharged through the discharge port 105, thereby facilitating the preparation and processing of the polycarbonate-based polyurethane thermoplastic elastomer raw materials by the preparation and mixing device main body 100.

[0032] Then, before the preparation and mixing device main body 100 prepares and mixes, the heat insulation cotton 1012 is closed inside the outer protection cylinder 1011, and the heat insulation cotton 1012 is fixed inside the outer protection cylinder 1011 by screwing the fixing installation edge ring 1014. Then, the outer protection cylinder 1011 is fixed on the outer surface of the preparation mixing tank 101 through the installation bolts 1015. After installation, when the preparation and mixing device main body 100 is subjected to heating treatment during the cold season, the heat dissipated from the outer surface of the preparation mixing tank 101 directly enters the interior of the heat preservation and heat storage tank 1013 for heat storage treatment. When storing heat in the heat preservation and heat storage tank 1013, it is insulated by the heat insulation cotton 1012 and is not easily dissipated to the outside, enabling the outer surface of the preparation mixing tank 101 to be heated for a long time and heating the interior faster, quickly heating for preparation and mixing treatment, and improving the heat preservation and mixing preparation effect of the preparation and mixing device main body 100 during the processing and preparation of the polycarbonate-based polyurethane thermoplastic elastomer material.

[0033] Finally, when the main body 100 of the mixing device is in the process of processing and mixing, and the motor 103 drives the rotating shaft 106 and the stirrer 107 to rotate, at this time, the bottom end of the rotating shaft 106 drives the support control frame 1062 and the stirring rod 1063 to rotate through the fixing ring 1061. When the support control frame 1062 rotates, the top end drives the rotating block 1065 to rotate inside the rotating groove 1064, which is convenient for stably rotating the support control frame 1062 to stably control the rotating shaft 106, so that the rotating shaft 106 and the stirrer 107 can perform more stable mixing and stirring treatment. When being stirred for a long time and being affected by the resistance of the material, it is not easy to cause instability. At the same time, the stirring rod 1063 rotates with the support control frame 1062 to uniformly stir and mix the inner surface edge of the mixing tank 101, making the stirring more stable and uniform, and improving the stability of the rotating shaft 106 and the uniformity of stirring when the main body 100 of the mixing device is used for processing and mixing polycarbonate-based polyurethane thermoplastic elastomer materials.
