Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a constant temperature device for producing sound-absorbing coating. Background Art

[0002] A stirring device is an important device that disperses and mixes materials by stirring. Especially in the production process of coatings, a stirring device is a necessary device. There are many types of existing stirring devices. According to the different characteristics of different materials, there are various stirring devices with different structures and performances. For liquid or molten materials such as coatings and paints, in the process of stirring, in order to prevent the materials from being affected by external cold air and solidifying, a constant temperature device is usually added to the stirring device. The existing stirring devices with constant temperature control function have a relatively simple structure and low heat conduction efficiency, resulting in uneven temperature and poor production effect. Therefore, those skilled in the art provide a constant temperature device for making sound-absorbing coatings to solve the problems raised in the above background technology. Utility Model Content

[0004] Preferably, a raw material inlet is provided on the upper side of the left cavity wall of the mixing cavity, and a mixed material outlet is provided on the lower side of the left cavity wall of the mixing cavity.

[0005] Preferably, a fixing seat is fixedly installed at the middle of the upper end of the mixing kettle, and a servo motor is fixedly installed at the side end of the fixing seat.

[0006] Preferably, a driving gear is fixedly mounted on the output shaft at the lower end of the servo motor.

[0008] Preferably: a double-layer toothed collar is provided at the upper side end of the mixing kettle, and the driving teeth and the supporting teeth are respectively engaged with the tooth patterns of the double-layer toothed collar, so that the driving teeth are driven to rotate by the servo motor, and the driving teeth force the double-layer toothed collar to engage with the supporting teeth, thereby driving the mixing rod to rotate, so as to ensure that the convex spiral blade can stably stir the coating raw materials in the mixing chamber.

[0009] Technical effects and advantages of this utility model:

[0010] When the utility model is used, the reflux liquid of the warm water tank is heated by an external circulating heating water pump and is re-directed into the spiral conduit to ensure temperature stability during the mixing process and achieve a good constant temperature effect for the paint. In this process, since the spiral conduit is arranged according to the outer contour of the convex spiral blade, the mixing direction of the paint raw materials in the mixing chamber during the mixing process is disordered, so that the mixed material sample is more uniform and the mixed material sample is subjected to more thorough heat exchange by the spiral conduit, thereby ensuring that the temperature fluctuation amplitude in the mixing chamber during the raw material mixing process is reduced and the internal constant temperature effect is increased.

[0020] When the present invention is used, the coating raw materials are put into the mixing chamber 10 through the raw material inlet 2, and the servo motor 14 is turned on to drive the driving teeth 15 to rotate.
