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

Abstract

The invention discloses a plastic extruder with stirring and pushing functions. The plastic extruder comprises a material barrel, wherein a charging port is formed in a charging end of the material barrel; a screw is arranged inside the material barrel, can rotate inside the material barrel and is provided with a threaded structure; and the threaded structure comprises a first threaded area and a second threaded area connected with the first threaded area, the first threaded area is close to the charging port of the material barrel, and the height of a thread of the first threaded area is higher than that of a thread of the second threaded area. The plastic extruder is good in stirring and pushing effects on molten plastics, and the requirement for the rotational torque of the screw is reduced.

Description

technical field [0001] The invention relates to the field of plastic thermal processing equipment, in particular to a plastic extruder with the function of stirring and pushing. 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, monofilam...
