Material strip granulation production process and material strip traction equipment used in material strip granulation production process

Abstract

The invention discloses a material strip granulation production process. The material strip granulation production process comprises the following steps: step 1, processing plastic raw materials by a material strip extruder and extruding plastic material strips; step 2, conveying the plastic material strips to a cooling water tank of material strip traction equipment to be cooled, and conveying the cooled plastic material strips by matching of a first section of conveying crawler belt and rotary rollers; step 3, conveying the plastic material strips to a second section of conveying crawler belt in an inclined state in the material strip traction equipment and carrying out air drying treatment on the plastic material strips by an air drying device; step 4, conveying the plastic material strips which are dried by air into a plate slot in the material strip traction equipment, and reshaping and conveying the plastic material strips by the matching of the second section of conveying crawler belt and the rotary rollers; and step 5, carrying out granulation treatment on the plastic material strips by a granulator. A complete stainless steel net crawler belt is composed of the first section of conveying crawler belt, the second section of conveying crawler belt and a third section of conveying crawler belt; the widths of holes in the stainless steel net crawler belt is less than 2mm; the stainless steel net crawler belt, the material strip extruder and the granulator are synchronously operated at an uniform operating speed.

Description

Technical field: [0001] The invention relates to the technical field of strip production equipment, in particular to a strip cutting production process and strip traction equipment used in the process. The strip traction equipment has a simple structure, uniform and neat traction strips, and an excellent traction effect. ideal. Background technique: [0002] Due to the shortage of plastic materials at present, the prior art is to crush various recycled plastic wastes, then heat and melt them into colloids, extrude them into strips, and then cut them into pellets by a granulator after cooling and drying before using them. [0003] At present, there are many tractors used in the production of plastic strips, and the shapes and sizes are also very different. Most of them use crawler tractors and belt tractors. Among them, the designed structure of crawler tractors is relatively complicated, and the cost and occupation The space is also relatively large, and it is uneconomical ...

Problems solved by technology

[0003] At present, there are many tractors used in the production of plastic strips, and the shapes and sizes are also very different. Most of them use crawler tractors and belt tractors. Among them, the designed structure of crawler tractors is relatively complicated, and the cost and occupation The space is also relatively large, and it is not economical to use; while the belt traction machine is relatively light and handy, and the cost is low, but its performance is poor, which directly affects the normal production of plastic strips.

In addition, in the process of pulling plastic strips, these two kinds of tractors cannot realize the uniform transportation of multiple plastic strips. When the section length and width of the plastic strips are not equal, the traction force of the plastic strips placed in different orientations will be different during the traction process, resulting in slippage, and finally one or more plastic strips cannot be pulled out
