Problems solved by technology

[0004] The heating device outside the head of the existing extruder only uses an external heater for heating, but this kind of heater is difficult to control the heating temperature of the head. For example, the temperature heated by the heater is too high, and it is difficult to reduce the temperature in a short time , affecting the quality of the produced product, resulting in product waste; and the distance between the heater and the cooling device is too far, and the temperature control accuracy is low, which affects the normal operation of the extruder

Embodiment

[0019] see figure 1 , the water-cooled heater in this implementation includes an annular heating jacket 1; a built-in cooling pipe 2 for cooling is built in the heating jacket 1, and the built-in cooling pipe 2 is an annular structure and the heating jacket The shape of the body 1 fits and surrounds the heating jacket 1, which forms an annular copper tube with three cooling tubes (see figure 2 with image 3 ). In this embodiment, the built-in cooling pipe 2 and the heating jacket 1 are formed by one-time casting, which is convenient for people to process and use.

[0020] On the heating jacket 1, an open end that can open the annular heating jacket is made. The opening end is made on the heating jacket 1 with an opening 11, and two installation bosses 12 are arranged at the position of the opening 11. Each mounting boss 12 is made with mounting holes for installing locking bolts 3, two mounting holes are provided, and two locking bolts 3 are installed, and the opening heat...

Abstract

The invention discloses a water-cooled heater which comprises a heating sleeve body and is characterized in that a built-in cooling pipe playing a cooling action is arranged in the heating sleeve body, the heating sleeve body is sleeved outside the head of an extruder, a heating sleeve is in a ring structure, and the built-in cooling pipe is encircled in the heating sleeve body. In the invention, the heating temperature of the heater can be regulated by placing a heating pipe in the heating sleeve body, thereby improving the temperature control precision and accuracy and reducing the product waste; a locking bolt and the annular heating sleeve body are adopted to facilitate installation and disassembly; and the water-cooled heater has the advantages of compact structure and convenient use and is worthy of being popularized and used.

Description

technical field [0001] The invention relates to an extruder heater, in particular to a water-cooled heater applied to the head of an extruder. Background technique [0002] Extruder is the most widely used equipment in polymer processing, and it is usually divided into single-screw extruder, twin-screw extruder and multi-screw extruder according to the number of screws. The screw extruder is composed of four parts: plasticizing system, heating and cooling system, transmission system and electrical control system; among them, the heating and cooling system is used in the extruder barrel, which is mostly heated by electric heaters. Cool with water or air. [0003] At the front of the extruder, the head part is composed of an alloy steel inner sleeve and a carbon steel outer sleeve, and a molding die is installed in the head. The function of the machine head is to transform the rotating plastic melt into a parallel linear motion, evenly and stably introduce it into the mold s...
