Description

Technical Field

[0001] The utility model relates to the technical field of extruder cooling mechanisms, in particular to a confluence core cooling system for extrusion equipment. Background Art

[0002] The confluence core is a connecting device between the extruder and the extrusion die. The plasticized melt of the extruder enters the confluence core and is completely in a molten state. It begins to change from a spiral motion with variable speed and pressure to a uniform linear motion, and builds up melt pressure through the die to make the temperature, viscosity and flow rate more uniform, making the final preparation for product molding.

[0003] In actual production and processing, production begins when the heating coil heats the plastic melt to the required temperature. The confluence core is in an over-temperature working state, and the plastic melt delivered to the mold will also be over-temperature. In severe cases, it is easy to paste, affecting various performance indicators of the product. Therefore, a cooling mechanism will be installed. The cooling mechanism is generally divided into water cooling and air cooling. The temperature of the coolant in the water-cooled cooling mechanism will rise after the cooling operation. If it continues to be used, the cooling effect will decrease. Therefore, the coolant needs to be replaced. Replacing the coolant will increase the time cost of workers, thereby affecting work efficiency. Improvements should be made to this problem.

[0004] For this purpose, a confluence core cooling system for extrusion equipment is proposed. Utility Model Content

The surface of the copper tube 405 is fixedly connected with the connecting pipe 502, and the other end of the connecting pipe 502 penetrates the surface of the box body 501 and extends to the inside of the box body 501. The end of the connecting pipe 502 is fixedly connected to the coil 503. A fan 504 is fixedly provided on the right side surface of the box body 501. The surface of the fan 504 is fixedly connected with an air pipe 505. The other end of the air pipe 505 is fixedly connected to an air collecting hood 506. A water pipe 507 is fixedly inserted at the bottom, and the bottom end of the water pipe 507 is fixedly connected to the surface of the water tank 401; specifically, the coolant flows through the copper tube 405 to the inside of the connecting tube 502 and is introduced into the inside of the coil 503 by the connecting tube 502. When the fan 504 is started, the surface of the coil 503 is cooled through the air pipe 505 and the air collecting hood 506, thereby cooling the coolant inside the coil 503.
