Problems solved by technology

The thread of the screw directly affects the ejection effect of the molten plastic. The thread height (1 / 2 of the difference between the major diameter and the small diameter of the thread) is too high, which requires a large rotational torque, and the thread height is too low. The injection speed of the plastic is slow or even reversed, causing the blockage of the barrel

Embodiment Construction

[0021] See figure 1 and figure 2 , An energy-saving plastic extruder of this embodiment includes a barrel 1, a drive motor 3 and a reducer 2, and a screw 4 is arranged inside the barrel, and the screw 4 can rotate in the barrel. The outer periphery of the barrel 1 is provided with a heater for heating and melting the plastic entering the barrel 1, the heater includes a plurality of first heaters 21 and a plurality of second heaters 22, the first heater 21 and the The second heaters 22 are arranged at intervals, and the temperature of the second heaters 22 is lower than the temperature of the first heaters 21 . That is, one or more second heaters 22 are provided between every two first heaters 21, which can not only ensure the heating and melting of plastic materials, but also minimize unnecessary heat energy consumption, which is more energy-saving and environment-friendly. The screw 4 includes a main thread 11 and a secondary thread 12 arranged in the thread pitch of the m...

Abstract

The invention discloses an energy-saving plastic extruder which comprises a material barrel. A threaded rod is arranged in the material barrel and can rotate in the material barrel, heaters are arranged on the periphery of the material barrel, the heaters comprise a plurality of first heaters and a plurality of second heaters, the first heaters and the second heaters are arranged at intervals, and the temperature of the second heaters is lower than that of the first heaters; the threaded rod comprises main threads, auxiliary threads arranged in spaces of the main threads, and the height of the main threads is larger than that of the auxiliary threads. The energy-saving plastic extruder is good in fused plastic stirring and pushing effect, capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention relates to the field of plastic thermal processing equipment, in particular to an energy-saving plastic extruder. Background technique [0002] The plastic extruder heats the plastic to make it into a viscous flow state. Under the condition of pressurization, it passes through a die with a certain shape to become a continuous body with a cross-section similar to the shape of the die, and then cools it to make it have a certain geometry. Plastics of shape and size change from a viscous fluid state to a highly elastic state, and finally cool and shape into a glass state to obtain the desired product. Through development for many years, plastic extruder derives twin-screw, multiscrew by original single screw rod, even does not have different types of machines such as screw rod. Plastic extruder (main machine) can be used with various plastic molding auxiliary machines such as pipe, film, handle material, monofilament, flat wire, packing bel...
