Intermittent feeding device

Abstract

The invention belongs to the field of production of powder coating, and particularly relates to an intermittent feeding device. The intermittent feeding device comprises an outer pipe, a conical protrusion arranged at the bottom of the outer pipe, and a plurality of stop pieces arranged around the conical protrusion. A motor is fixed to the bottom of the conical protrusion. An output shaft of themotor is connected with the stop pieces to drive the stop pieces to move in the circumferential direction. A plurality of material outlets are formed in the side wall of the conical protrusion. According to the intermittent feeding device, materials are shifted into a material outlet continuously from a pipeline by means of the rotation of the stop pieces, the rotation of the stop pieces is controlled by the motor, and the rotation speed is also controlled, so that intermittent feeding is achieved, and the situation that materials are stacked at an inlet of an extruder and consequentially, theworking efficiency of the extruder is affected is avoided.

Description

technical field [0001] The invention belongs to the field of powder coating generation, and in particular relates to an intermittent feeding device. Background technique [0002] Coating refers to a class of liquid or solid material that is coated on the surface of an object and can form a film under certain conditions for protection, decoration or other special functions. Powder coating is a new type of solvent-free, 100% solid powder coating, which has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of the coating film. The wider the application. [0003] In the production process of powder coatings, it usually includes premixing, fusion, extrusion molding to make flake materials, and then cooling, crushing, grinding, grading and screening into powdery electrostatic spraying materials. In order to save space, the premixing tank is usually set In t...

Problems solved by technology

[0003] In the production process of powder coatings, it usually includes premixing, fusion, extrusion molding to form sheet materials, and then cooling, crushing, grinding, grading and screening into powdery electrostatic spraying materials. In order to save space, the premixing tank is usually set In the upper space, the extrusion molding equipment is placed in the lower space, such as patent number 208627511 U, but because the mixing and extrusion molding are set on different floors, when transporting materials in the pipeline connecting the two, it is easy to cause material breakdown. Accumulation, which affects the production efficiency of the extruder
