The barrel 1 is provided to be installed at the feed of the horizontal injection molding machine and store the material. The material enters the interior of the horizontal injection molding machine through the discharge pipe 2.

By setting the water inlet pipe, it is used to inject coolant into the annular tube 5, and the coolant can absorb the heat emitted by the discharge pipe 2 through the inner wall of the annular tube 5.

[0026] Furthermore, by starting the pump 9, the water flow in the annular tube 5 passes through the first tube body 6 and the serpentine tube 7 through the pump 9, and then enters the annular tube 5 again through the second tube body 10, thereby realizing the circulation of the coolant, which can better absorb the heat emitted by the discharge pipe 2 and achieve the purpose of cooling the discharge pipe 2. In this way, it can prevent the discharge pipe 2 from being overheated, causing the material to melt, and causing the discharge pipe 2 to be blocked.

[0027] It is worth noting that: a support plate 3 is provided on one side of the barrel 1, a connecting rod 4 is connected to one side of the support plate 3, and one end of the connecting rod 4 is connected to the surface of the barrel 1; a heat dissipation component for air cooling and heat dissipation of the temperature control component is installed at the bottom of the support plate 3, and the heat dissipation component includes a fan 11 installed on the top of the support plate 3, and the exhaust end of the fan 11 is connected to the air duct 12, and one end of the air duct 12 passes through the support plate 3 and extends to one side of the shell 8 and is connected to the exhaust hood 13. One side of the exhaust hood 13 is connected to the upper side of one side of the shell 8, and the bottom of the shell 8 is provided with an exhaust groove 14.

The detection end of the thermometer 17 can monitor the temperature of the coolant inside the ring pipe 5. Compared with the traditional method of directly connecting the detection probe to the discharge pipe 2, the contact with the coolant can reduce the damage to the probe. When the temperature of the coolant is too high, the thermometer 17 transmits the temperature signal to the controller 16. The controller 16 starts the pump 9 and the fan 11. The temperature of the discharge pipe 2 is reduced by circulating the coolant to prevent the material from melting and clogging, thereby achieving the purpose of monitoring the temperature of the hopper.
