The die head of the film blowing machine can heat and melt the plastic particles during operation, and then make them into films. Because the variety of plastic is very rich, and the use of plastic film is also relatively wide, so how do we adjust the accuracy of the die head of the film blowing machine in use?

The unit selects the advanced spiral die head structure. According to the particularity of high pressure, low pressure, mix and recycled polyethylene material, the main technical parameters such as spiral Angle, regression Angle, length of shaping Angle and die opening are designed comprehensively. After many comparative tests, the main technical parameters are selected and shaped, including the core with spiral channel, feed port and die barrel. Inner die, die ring and discharge port. An inner mouth die is arranged in the middle of the die ring of the product, and a discharge mouth is arranged between the inner die and the die ring of the product.

The upper part of the barrel of the die head of the film blowing machine is provided with a feeding port, and the inner spiral core with a spiral channel is provided below the feeding port of the product. The middle spiral core and the outer spiral core are respectively connected with the feeding port, and the reduced connection body of the product is arranged under the spiral core. And a coarse mold adjusting ring, a fine mold adjusting ring and a fine-tuning mold ring are arranged at the merging outlet of the inner layer, middle layer and outer spiral core of the product. Adjusting bolts are arranged around the respective die rings of the product. According to the die head of the film blowing machine, the accurate adjustment device will bring positive use effect to the vast plastic film production industry.
