Novel efficient energy-saving low smoke zero halogen extruder

Abstract

The invention discloses a novel efficient energy-saving low smoke zero halogen extruder. The novel efficient energy-saving low smoke zero halogen extruder comprises a rack, and a spiral cylinder is arranged on the rack. A plurality of heating partitions are evenly arranged on the cylinder wall of the spiral cylinder and are sleeved with an electromagnetic heating device in a fixed mode. A threaded rod is arranged in the spiral cylinder, and extruding threads are arranged on the surface of the threaded rod. The surface of the threaded rod is sequentially divided into a power input part, a feeding section, a primary compression section, a primary fusion section, a secondary compression and fusion section and a metering section. The power input part is connected with a power mechanism. Distances and depths of the threads at the feeding section are equal. Distances of the threads at the primary compression section are equal, and the depths of the threads at the primary compression section are not equal and gradually become larger. Raw materials are fused at the primary fusion section and extruded into the secondary compression and fusion section. An assisting thread matched with the extruding threads is arranged on the surface of the secondary compression and fusion section, and the secondary compression and fusion section conducts compression and fusion at the same time. The novel efficient energy-saving low smoke zero halogen extruder is reasonable in design, convenient to operate, capable of effectively controlling temperature and environmentally friendly, the production speed is increased, and energy is saved.

Description

technical field [0001] The invention relates to the field of extruders, in particular to a novel high-efficiency, energy-saving, low-smoke and halogen-free extruder. Background technique [0002] The low-smoke and halogen-free extruder is a device that extrudes and melts plastic raw materials to prepare products. It is mainly composed of internal screw barrels, screws and heating components. The existing low-smoke and halogen-free extruders generally have low output and low temperature. Difficult to control and other shortcomings. In the past, the control temperature of the screw barrel was four sections, and the cast aluminum heating coil was used as the heating part, which required a lot of energy consumption to meet the heating requirements, and through the temperature detection during use, it was found that the difference between the detected temperature and the actual temperature was at least 15 degrees. Cause temperature control difficulty to increase, and product qua...

[0002] The low-smoke and halogen-free extruder is a device that extrudes and melts plastic raw materials to prepare products. It is mainly composed of internal screw barrels, screws and heating components. The existing low-smoke and halogen-free extruders generally have low output and low temperature. Disadvantages such as difficult to control

In the past, the control temperature of the screw barrel was four sections, and the cast aluminum heating coil was used as the heating part, which required a lot of energy consumption to meet the heating requirements, and through the temperature detection during use, it was found that the difference between the detected temperature and the actual temperature was at least 15 degrees. As a result, it is more difficult to control the temperature, and there are problems with product quality.

And when extruding, the existing screw cannot achieve the effect of extrusion speed, high quality, and high control, and often only this kind of adjustment is required, and the production capacity is greatly reduced
