[0002] Temperature control is a key point in the production of BMC / SMC materials. Different seasons and weather conditions will lead to different initial mixing temperatures, and the overall temperature rise caused by mixing heat will also vary. However, conventional BMC / SMC mixer temperature control relies on manual judgment. The cooling water is turned on according to different air temperatures and measured temperatures to ensure that the temperature does not exceed the limit. This method is difficult to ensure temperature control accuracy. In addition, existing BMC / SMC mixers are difficult to achieve rapid automatic temperature control, resulting in not only a low degree of automation but also low temperature control efficiency.

[0003] In order to address the deficiencies in the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses an automatic temperature control system for a BMC kneading machine [CN202222231663.7], which includes a base, a jacket, a mixing tank for kneading BMC materials, and a single-chip microcomputer for controlling the mixing tank.

[0026] Among them, the temperature regulating component 4 includes a loading chamber 41 arranged on the circumferential inner wall of the stirring tank body 1, and a number of circumferential flow pipes 42 are arranged equidistantly from top to bottom in the loading chamber 41. The circumferential flow pipes 42 are connected by a vertically arranged first guide pipe 43.

[0027] The circumferential flow pipe 42 is used to guide the cooling liquid or the heating liquid. The first guide pipe 43 is used to guide the cooling liquid and the heating liquid into each circumferential flow pipe 42 from top to bottom to achieve circumferential temperature control.

[0028] Obviously, the first flow guide pipe 43 is staggered between the gaps of two adjacent circumferential flow pipes 42 , and the first flow guide pipe 43 at the upper end is connected to the flow inlet 44 arranged at the upper end of the mixing tank body 1 .

[0029] This arrangement allows the circumferential flow channel 42 to be gradually filled with cooling liquid or heating liquid from top to bottom.

[0030] Furthermore, an inlet solenoid valve 45 is provided at the inlet 44 and is opened and closed by the control module 3 .

[0031] The inlet solenoid valve is a two-way valve, which is connected to the heating liquid tank and the cooling liquid tank respectively, and is opened and closed by the control module 3 according to the set warning temperature value.

[0032] Furthermore, a bottom flow pipe 6 arranged in an annular shape is embedded in the bottom of the mixing tank body 1 , and the bottom flow pipes 6 are connected by a second flow guide pipe 61 arranged in a horizontal direction.

[0033] Specifically, the second flow guide pipe 61 is staggered in the gap between two adjacent bottom flow pipes 6 , and the second flow guide pipe 61 located on the outer circle is connected to the discharge port 62 arranged at the lower end of the mixing tank body 1 .

[0034] The bottom overflow pipe 6 is used in conjunction with the circumferential overflow pipe 42 to achieve circumferential temperature control of the stirring tank body 1, thereby improving temperature control efficiency.

[0035] More specifically, a discharge solenoid valve 63 is provided at the discharge port 62 and is opened and closed by the control module 3 .

[0036] The discharge solenoid valve 63 is a two-way diverter valve, which is connected to the cooling liquid tank and the heating liquid tank through discharge pipes respectively, and is used to discharge the cooling liquid or heating liquid in the bottom overflow pipe 6 and the circumferential overflow pipe 42.
