Embodiment

[0031] Such as figure 1 The foam plastic environmental protection recycling granulation unit shown is composed of a feeding conveyor A, a foam plastic special pulverizer B, a feeding fan and a conveying pipeline C, a main machine D, a water tank E, a granulator F, a storage tank and a weighing machine. Heavy equipment G composition.

[0032] Conveyor for feeding

[0033] The entire conveying mechanism is composed of a traction wheel, a driven wheel, a conveyor belt, a corner rubber block and a motor with a reducer. And the main frame and conveyor belt of the conveyor are designed to be widened and heightened, especially for the transportation of foam plastics. According to the actual use requirements, a metal detector is also configured.

[0034] grinder

[0035] As shown in Fig. 2 and Fig. 3, the feed body is composed of an upper body 1 and an intermediate body 2 connected under the upper body. The upper body and the intermediate body are connected by bolts 8. The functio...

Abstract

The invention relates to a compression extruding host machine for a formed plastic environment-friendly recovering and granulating machine set, which is characterized in that the compression extruding host machine consists of a primary compression extruding part and a secondary compression extruding part, wherein the primary compression extruding part is a semi-fluid state formed by melting formed plastic materials and exhausting air; and the secondary compression extruding part performs secondary exhausting extrusion. The depth of a spiral groove of a main extruding spiral rod in the primary compression extruding part is 1 / 3 of the diameter, the thread pitch is 0.75 to 1 time of the diameter, and the 1 / 4 to 1 / 3 circle of the front end part is provided with head symmetrical extruding screws. The inside of a main material barrel discharge plate is provided with an inclined surface with conicity, the front side of the main material barrel discharge plate is provided with a plurality of small holes which are distributed according to an inverted equilateral triangle, and the outer side face of the small holes of the main material barrel discharge plate is provided with protection steps. The compression extruding host machine adopts a closed circular material supply system, improves the environment-friendly regeneration utilization rate, ensures that the light formed plastic materials are compressed and extruded at a high speed, improves the extruding and granulating efficiency and the operability, and ensures that the manufactured granules are uniform in size, full and glossy.

Description

technical field [0001] The invention relates to a plastic processing machine, in particular to a compression extruding host of a foam plastic recycling granulation machine. Background technique [0002] Expandable polystyrene foam (EPS) is widely used in various production fields such as industry and agriculture, as well as in civil and daily life. But the recycling of foamed plastics in the prior art is in a relatively open environment, the production efficiency is low, the production cost is high, and the environmental pollution is very serious in the production process, and the working environment of the operators is bad. Contents of the invention [0003] The present invention mainly solves the deficiencies in the prior art, so as to develop a compression extruder main engine of a foam plastic environmental protection recycling granulation unit that adopts a closed cycle feeding system, saves energy loss and reduces secondary pollution of recycling. [0004] The above...
