AI Technical Summary
The existing automotive sealant mixing tanks have uneven material mixing, especially in the middle area near the rotating shaft and the bottom area of the mixing tank, which leads to a decrease in sealant performance. In addition, the motor is prone to damage due to excessive power during startup, and the bearings are severely worn.
Bow-shaped stirring blades and electric heating blocks are installed inside the mixing tank. The stirring blades are symmetrically distributed on both sides of the stirring shaft, and the electric heating blocks are symmetrically arranged along the center of the stirring shaft. They are used to heat the sealant liquid and balance the stirring blades, thus extending the bearing life.
This method achieves uniform mixing and constant-temperature stirring of the sealant, improves stirring efficiency, extends the service life of the stirring bearing, and reduces the starting load of the motor.

TECHNICAL FIELD
[0001] The utility model belongs to other mixing machine, mixing equipment, including the technical field of combination of different mixing machine, specifically relates to a heating device arranged in the sealant mixing tank. BACKGROUND
[0002] In the production process of automobile sealant, the solid-phase material and the liquid-phase material need to be fully stirred in the stirring kettle in advance, and then sent to the mixing kettle for mixing, and liquid-phase material is added as needed to control the viscosity, solid-liquid ratio and other parameters of the sealant, and the material mixed by the mixing kettle is discharged through the discharge device. Figure 1 And Figure 2 As shown in the structure diagram of the existing stirring kettle, the mixing uniformity of the material in the middle region B near the rotating shaft and the bottom region C of the stirring kettle is less than that in region A of the stirring blade, which leads to insufficient mixing of the material and easily causes great negative impact on the performance of the sealant. Generally, the mixing uniformity and sealing performance of the mixed liquid just discharged from the stirring kettle are worse than those of the mixed liquid discharged later. In addition, the stirring blades in the existing stirring kettle are symmetrical in structure, large in volume and large in stirring force area. In particular, when the motor starts stirring, the instantaneous power of the motor exceeds 3-5 times of the normal working power, which easily damages the motor. Once the motor is damaged, the mixed material in the stirring kettle needs to be stirred by replacing the kettle, which easily reduces the quality of the sealant.

This single-sided blade structure is prone to wear during implementation due to the uneven weight distribution, and the stirring shaft is more prone to wear than the double-sided blade bearing, which has a short service life. In order to improve the service life of the bearing, the stirring device needs to be further improved. SUMMARY
