Abstract

The invention discloses a double-die-head device of a plastic compound machine. The double-die-head device comprises a tee joint, two die heads, four amplitude modulators and four sets of sealing devices. Each amplitude modulator comprises a screw, a nut, a filler gauge, a fixing frame and a hand wheel. The positions of the filler gauges in the die heads can be adjusted by shaking the hand wheels so as to control the plastic coating compound width. The effect of sealing at the moving positions of the filler gauges in the die heads is achieved in the manner that plastic sheets and inner pressing blocks are arranged in a metal frame and a plastic frame in a sleeved manner, and outer pressing blocks are used for conducting pressing to make the plastic sheets inwards hold the filler gauges tightly. The double-die-head device has the beneficial effects that due to the fact that the technology is adopted, amplitude modulation is easy, convenient and reliable to conduct through the hand wheels, no leakage phenomenon is generated, the uniformity and compactness of the thickness of an extrusion film can be improved, and the phenomenon of forced shutdown caused by leakage does not exist; and the product quality is improved, and the production efficiency and the enterprise economic benefits are greatly improved.

Description

[0001] The invention relates to the field of packaging machinery, in particular to a double-die device of a plastic compound machine. [0002] technical background [0003] At present, the packaging bags used in various industries at home and abroad, among which the amount of laminated plastic woven bags is particularly large, and its production process is plastic raw materials-plastic wire drawing machine drawing flat wire-plastic circular loom weaving cylindrical cloth-plastic compound machine coating Composite-bag-making machine-made bags, in which the plastic compound machine is used for the plastic coating and compounding process, the extruder is generally used to extrude the double-die head to compound the two sides of the folding diameter of the plastic woven barrel bag at the same time. This compounding process and equipment is simple and reliable. It is easy to operate and low in production cost, but it is difficult to adjust the amplitude. When producing plastic-coated...
