Introduce the feeding device of spiral wound pipe machine

The spiral wound pipe machine generally uses pellets as the material, but strips or powders can also be used. The filling equipment of the spiral wound plastic pipe machine usually uses a conical feeding hopper, whose volume is required to provide at least an hour's consumption. There's a cutting device at the rock bottom of the hopper to regulate and bring to a halt the fabric flow. The facet of the hopper is provided with a sight hole and an activity metering device. Some hoppers may also be equipped with pressure-reducing devices or heating devices to prevent the raw materials from absorbing moisture from the air, or some barrels also have their agitators, which can automatically feed or feed materials. Next, let's take a look at the introduction of the feeding device of the spiral wound pipe machine. Here are some answers.

Description of the hopper of the spiral wound pipe machine.

The hopper of the spiral wound pipe machine is generally symmetrical. There's a window on the facet of the hopper to watch the fabric level and feeding state of affairs, and also the bottom of the hopper has a gap and shutting door to prevent and change the feeding quantity. A cover is added above the hopper to prevent dust, moisture, and impurities from falling into it. When choosing the material of the hopper, it is best to use lightweight, corrosion-resistant, and easy-to-process materials. Generally, aluminum and stainless steel plates are used. The degree of the hopper depends on the scale of the extruder and also the feeding methodology. Generally, the extrusion capacity of the extruder is 1 to 1.5 hours.

How is the spiral wound pipe machine loaded?

There are unit 2 varieties of feeding methods: manual feeding and automatic feeding. Automatic feeding mainly includes spring feeding, blast feeding, vacuum feeding, conveyor belt conveying feeding, and other forms. Generally, manual feeding is used for small HDPE spiral tanks, and automatic feeding is used for large spiral wound pipe machines.

There are two types of feeding methods for spiral wound pipe machines.

Gravity feeding

The principle of gravity feeding is that the material enters the barrel by its weight, including manual feeding, spring feeding, and blast feeding. Its characteristics are simple in structure and low in cost. However, it's simple to cause uneven feeding, which affects the standard of the elements. It is only suitable for small-sized spiral wound pipe machines.

Forced feeding

The principle of forced feeding is to install a device that can apply external pressure to the material in the hopper to force the material into the spiral wound pipe machine barrel. Forced feeding can overcome the "bridging" phenomenon and make feeding even. The feeding screw is driven by the spiral wound HDPE pipe machine through the transmission chain so that its speed is compatible with the screw speed. The overload protection device will be activated once the feeding port is blocked, thereby avoiding harm to the feeding device.
