Abstract

The invention belongs to the technical field of extruders, and relates to a multi-section composite screw. The multi-section composite screw comprises a screw head, a controller, a first screw body, first sliding rails, connecting columns, third screw bodies, rotary shafts, a fourth screw body, second motors, first air cylinders, an eighth screw body, a second double-end air cylinder, second sliding blocks, second sliding rails, a second groove, tenth screw bodies, a ninth screw body, second air cylinders, fifth screw bodies, sixth screw bodies, first grooves, seventh screw bodies, first motors, shaft sleeves, a first double-end air cylinder, a second screw body and first sliding blocks. The first sliding rails are mounted on the right side of the first screw body and the left side of the fourth screw body correspondingly and provided with the two first sliding blocks. The connecting columns are mounted on the first sliding blocks and provided with the two rotary shafts. The third screw bodies are mounted on the rotary shafts, and the two third screw bodies are engaged with each other to form a dual screw. The first motors are mounted in the connecting columns, and output shafts of the first motors stretch out of the connecting columns. The multi-section composite screw has the beneficial effect of being provided with auxiliary screws.

Description

technical field [0001] The invention relates to a multi-section composite screw, which belongs to the technical field of extruders. Background technique [0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main engine, and the subsequent equipment plastic extrusion molding machine is called the auxiliary machine. Plastic extruder derives twin-screw, multiscrew, even does not have different types of machines such as screw rod with original single screw rod through 100 years of development. The plastic extruder can be matched with various plastic molding auxiliary machines such as pipe, film, handle material, monofilament, flat wire, packing belt, extruded net, plate, profiled material, granulation, cable coating, etc., to form various plastic extruders. A molding production line is produced to produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used models in the plastic processing indu...
