Embodiment Construction
[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0041] This embodiment provides a combined extruder barrel, which consists of multiple figure 1 , figure 2 with image 3 The shown barrel unit 100 is connected sequentially, and the barrel unit 100 includes:
[0042] Outer cylinder 1;
[0043] An inner bushing 2 made of metal material, the inner bushing 2 can be sleeved in the outer cylinder 1 and has an interference fit with the outer cylinder 1;
[0044] The outer cylinder 1 has at least one first end f...

The invention discloses a combined extruder barrel and an assembly method thereof. The barrel is formed by a plurality of barrel units which are connected in sequence, wherein each barrel unit comprises an outer barrel and an inner bushing between which an interference fit is formed. According to the barrel, to replace the worn inner bushing in the single barrel unit during use is convenient. Through the assembly method, all of the barrel units can be kept to the same size, and are of high coaxiality; and after the assembly, neither leakages nor stepped faces can occur between the barrel units, so as to ensure the normal operation of an extruder and the quality of a finished product. In addition, insert block structures of the barrel are easy to change after being worn and can be demountedin different working conditions, so that the extruder barrel can be equipped with auxiliary mechanisms, such as an air exhaust mechanism and a side feeding mechanism, to improve the quality of a processed product and the use flexibility of the barrel.
Description
technical field [0001] The invention relates to the field of extruders, in particular to a combined extruder barrel and an assembly method thereof. Background technique [0002] The barrel of the extruder is generally divided into integral type and combined type, of which: [0003] The barrel structure of the integral barrel is an integral structure, and its screw lining structure is generally also an integral structure or an integral structure with the inner wall of the barrel, but no matter which structure the lining adopts, once the lining is in use Wear and tear occurs during the process, and it is necessary to replace the inner liner or even replace the barrel as a whole. [0004] The combined barrel is formed by matching multiple sections sequentially, which has the advantage of being able to replace the severely worn barrel or lining separately, saving maintenance costs. However, in order to facilitate assembly, the cylinder body and the lining of the combined barre...
