Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same symbols may be attached to the same constituent elements, and overlapping descriptions will be omitted. In addition, in order to facilitate understanding of the drawings, each component is schematically shown on the main body. In addition, the thickness, length, number, and the like of each component shown in the drawings are different from actual ones in consideration of the convenience of drawing.

[0025] Such as figure 1 As shown, the resin recovery apparatus of this embodiment has a structure in which the pulverization unit 1, the separation unit 2, the measurement addition unit 3, and the stirring unit 4 are arranged vertically downward in this order. When the waste resin 5 of the sprue part or molded defective products is input from the upper side of the resin recovery device (the input port of the crushing part 1), the recovered resin parts 6 will be d...

Abstract

The invention provides a small resin recovery device which is small in area and is short in delivery path. The resin recovery device can carry out the procedures of waste resin smashing, powdery resin separation and removal, powdery resin measurement, antioxidant addition, and mixture stirring. In the resin recovery device, a smashing part, a separating part, a measuring and adding part, a stirring part are arranged below a plumb in order. The separating part is provided with an air inlet which enables the air generating the eddy flow to flow to the inside of the separating part from the upper part of the separating part, an air outlet which discharges the air in the separation part from the lower part of the separation part, and mesh openings which divide the inside area of the separation part into a peripheral area and an area which is closer to the inside than the peripheral area.

Description

technical field [0001] The present invention relates to a resin recycling device for reusing waste resin such as a runner part and molded defective products. Background technique [0002] As a method of forming recycled resin parts, the following method is known: after the waste resin of the sprue part or the molded defective product is pulverized, the fine powdery resin is separated and removed from the pulverized resin (pulverized resin), and then the resin is removed. The weight of the pulverized resin after the powdered resin is measured, and an antioxidant in an amount corresponding to the measured weight is added to the pulverized resin, and then the pulverized resin is softened by frictional heat of stirring, and the antioxidant is attached to the pulverized resin. Crush the resin. The above process is processed in multiple devices. For example, refer to Japanese Patent JP2007-117837A. Figure 5 It is a figure which shows the conventional resin recovery apparatus di...
