Packing belt production equipment configuration

Strapping we are very familiar with, then packaged with the production and how much you really a process of understanding, the following small series tell you about packing tape production process, from the configuration strap production machine to form a band packing I will give you a brief introduction.

Packing belt production equipment configuration: plastic extruder (host / auxiliary machine), cooling water tank, oven, traction embossing unit, Tape winding machine.

The main and auxiliary drive of the strapping production line consists of a speed-regulating motor, a reducer and a bushing. The molding part is composed of a screw barrel, a machine head and a die. The raw material is heated and extruded through the hopper to the screw barrel to exfoliate the embryo. The first stage controlling body temperature --120 ° --170 second section of the third section --220 degrees, 250-280 degrees nose.

The packing belt production line lowers the initial embryo cooling of the main and auxiliary machine. After the material is taken out, the temperature is very high, and it should be immediately cooled into the water, because the isotactic polypropylene is easy to form a twin structure in the case of rapid cooling, and the twin crystal structure is relatively loose. Easy to stretch orientation for high quality products. The cooling water temperature of the packing belt production line is generally controlled at 30-40 degrees, and the distance between the mold belt production line and the water surface is preferably 15-45 mm.

The first traction of the strapping production line consists of a speed regulating motor, a speed reducer, a chain drive, and a traction roller. It transports the preformed embryos to the oven.

The secondary heating of the lowering oven of the packing belt is convenient for stretching; the purpose of stretching is to increase the longitudinal strength of the packing belt and reduce the elongation. The drying of the oven in the packing belt production line eliminates the tensile stress three times; the upper tank eliminates the thermal stress and is shaped.

The belt conveyor production line embossing machine transmission is the speed control motor through belt drive, chain drive, gear transmission to the second traction, to embossing, to the third traction. The second traction re-stretches the secondary heated primary embryo through the tension bar and simultaneously feeds it to the embossing roller; the stretched packaging tape passes through the two patterned pressure rollers, and is pressed onto the pattern, and the effect is Increase friction during use, do not slip, look beautiful from the outside. The surface of the product is embossed by the embossing roller and then conveyed to the upper tank or the upper oven; the strapping production line conveys the forming of the upper tank to the winding machine through the third pulling.
