Problems solved by technology
[0003] Whether the existing polyurethane pouring machine is a high-pressure machine or a low-pressure machine, the high pressure in the mixing chamber will increase the temperature of the head of the polyurethane pouring machine, and relying on the rapid rotation of the stirring head to mix the two materials will also increase the temperature of the head of the polyurethane pouring machine. Excessive temperature of the machine head will cause damage to itself and affect the life of the machine head

Embodiment
[0032] Example: such as Figure 1-7 As shown, it includes the driver 1, the combined liquid distribution valve body 2, the sleeve 3, the cooling device 20, the cooling fin 21 and the heat dissipation sleeve 11; The combined valve body 2 for power and liquid distribution is used for the input of two kinds of raw materials. The sleeve 3 is located under the driving member 1, and the sleeve 3 is located inside the combined liquid distribution valve body 2 to protect the transmission shaft 4 inside it. The cooling device 20 is located on the left and right sides of the combined liquid mixing valve body 2, and converts the rotational motion of the stirring shaft 5 into a back and forth motion. The heat sink 21 is connected to the outside of the heat sink 20, and the heat sink 21 moves back and forth to promote the circulation of heat in the air, thereby accelerating the heat dissipation of the pouring machine head. The heat dissipation cover 11 is located between the heat dissipa...

The invention discloses a polyurethane pouring machine head with heat dissipation function, which belongs to the technical field of polyurethane pouring, and comprises a driving part, a combined liquid mixing valve body, a sleeve, a heat dissipation device, a cooling fin and a cooling sleeve; Above the liquid combination valve body, the sleeve is located under the driving part, the sleeve is located inside the liquid distribution combination valve body, the heat dissipation device is located on the left and right sides of the liquid distribution combination valve body, and the heat sink is connected to the heat dissipation device On the outside, the heat dissipation sleeve is located between the heat dissipation fins. The invention is scientific and reasonable, safe and convenient to use, and the heat dissipation sleeve transfers the heat of the pouring machine head to the air, which is beneficial to the heat dissipation of the pouring machine head; the heat dissipation sleeve is equipped with hook-shaped blocks and buckles, which is convenient for installation and increases heat dissipation efficiency; Using the rotating power of the stirring shaft, combined with gears and other components, it drives the swing piece to move back and forth, accelerating the heat dissipation in the air and increasing the heat dissipation efficiency; the stirring shaft is also equipped with a sealing ring to effectively prevent material from leaking out.
Description
technical field [0001] The invention relates to the technical field of polyurethane pouring, in particular to a polyurethane pouring machine head with heat dissipation function. Background technique [0002] The polyurethane pouring machine is mainly used in the continuous production of polyurethane products or polyester elastomer products. The pouring volume can be adjusted according to the demand. It has a temperature control system, an automatic feeding device, etc. The production process is: under the action of specific temperature and pressure, the two raw materials are sent from their respective tanks to the mixing chamber of the pouring head according to a certain ratio, and then through the high-speed rotation of the mixing head spindle, and using the mixing head on the mixing head The thrust generated by the spiral structure quickly stirs the two raw materials in the mixing chamber of the injection nozzle device, causing them to undergo a chemical reaction, and fina...
