The spiral wound pipe machine is a new product that replaces the metal spring for the protection of traditional hoses. The spiral wound pipe machine is generally made of nylon or polypropylene. The production equipment of winding pipe includes a plastic extruder, sheath winding machine, vulcanizing tank, etc. This section will introduce the plastic extruder which is one of the components of a spiral wound pipe machine. The main machine of the spiral wound pipe machine is an extruder, which consists of an extrusion system, a transmission system, and a heating and cooling system.
Here is the content list:
Heating and cooling device
Spiral wound pipe machine plastic extruder In plastic extrusion molding equipment, the plastic extruder is usually called the main machine, while the spiral wound pipe machine plastic extruder and its supporting follow-up equipment are called auxiliary machines. . After more than 100 years of development, the spiral wound pipe machine plastic extruder has been derived from the original single screw, multi-screw, or even non-screw and other models. The spiral wound pipe machine plastic extruder (host) can form various plastic extrusion molding production lines to produce various plastic products. Therefore, the spiral wound pipe machine plastic extruder is one of the widely used machines in the plastics processing industry no matter now or is the future.
The spiral wound pipe machine plastic extruder extrusion system includes screw, barrel, hopper, die, and die. The plastic is plasticized into a uniform melt through the spiral wound pipe machine plastic extruder extrusion system. Under the pressure established in the process, the extruder head is continuously extruded by the screw.
The spiral wound pipe machine plastic extruder drive system is used to drive the screw and supply the torque and speed required by the screw during the extrusion process. It is usually composed of a motor, a reducer, and a bearing.
Spiral wound pipe machine and on the premise that the structure is the same, the manufacturing cost of the reducer is roughly proportional to its outer size and weight. Because of the large shape and weight of the reducer, it means that a lot of materials are consumed during manufacturing, and the bearings used are also relatively large, which increases the manufacturing cost.
The spiral wound pipe machine extruder with the same screw diameter, the high-speed and efficient spiral wound pipe machine extruder consumes more energy than the conventional spiral wound pipe machine extruder, the motor power is doubled, and the base of the reducer It is necessary to increase the number accordingly. But a high screw speed means a low reduction ratio. Compared with the spiral wound pipe machine plastic extruder with a large reduction ratio, the gear modulus of the same size reducer, the spiral wound pipe machine plastic extruder with low reduction ratio is increased, and the load-bearing capacity of the reducer is also increased. The spiral wound pipe machine plastic extruder, therefore, increases in volume and weight of the reducer, not linearly proportional to the increase in motor power.
Heating and cooling are necessary conditions for the spiral wound pipe machine plastic extrusion process to be carried out.
⑴Spiral wound pipe machine extruder usually uses electric heating, which is divided into resistance heating and induction heating. The heating piece is installed in the body, neck, and head of the spiral wound pipe machine plastic extruder. The heating device uses the spiral wound pipe machine to heat the plastic in the barrel outside of the plastic extruder to heat, and use the spiral wound pipe machine to extrude the plastic to the temperature required for the process operation.
⑵The cooling device is set up for a spiral wound pipe machine plastic extruder to ensure that the plastic is in the temperature range required by the process. Specifically, the spiral wound pipe machine plastic extruder removes the excess heat generated by the shear friction of the screw rotation, to prevent the plastic from decomposing, scorching, or shaping difficult due to excessive temperature. The barrel cooling of spiral wound pipe machine plastic extruder is divided into water cooling and air cooling. Generally, air cooling is more suitable for small and medium-sized extruders, while large spiral wound pipe machine plastic extruders mostly use water cooling or a combination of the two. Cooling; screw cooling of spiral wound pipe machine plastic extruder mainly adopts central water cooling, the purpose is to increase the solid conveying rate of spiral wound pipe machine plastic extruder, stabilize the amount of glue, and improve the productivity of spiral wound pipe machine plastic extruder.
