Embodiment

[0020] There are respectively fixed first passing roller 1 and second passing roller 3 on both sides of the force measuring passing roller, so that the natural plain film passing through these three passing rollers forms a fixed angle β on the force measuring passing roller, and the size of the included angle β is 105°, the force sensor accurately measures the film tension, and converts the tension into an electrical signal and feeds it back to the coil diameter tension controller. After the tension controller calculates according to the pre-set tension value, it controls the coiling by controlling the frequency converter The output rotational speed of motor 6, thereby automatically controls tension constant in the coiling process. The inverter model is Danfoss FC302, and the coiling motor is a 5.5Kw variable frequency motor.

Abstract

The invention discloses a constant-tension coiling device for a natural-element membrane forming machine, which relates to the technical field of a rubber machine. The constant-tension coiling device comprises a first passing roll (1), a second passing roll (2), a dynamometry passing roll, a coiling roll (5), a dynamometry sensor (2), a coiling-diameter tension controller, a variable-frequency speed regulator and a coiling motor (6), wherein the dynamometry sensor (2) is used for detecting the tension of a natural-element membrane and feeding the tension back to the coiling-diameter tension controller, the coiling-diameter tension controller controls the frequency converter after the calculation is carried out according to the given tension, and the rotation speed of the coiling motor (6) is adjusted through the variable-frequency speed regulator to realize the constant-tension coiling. By adopting the constant-tension coiling device, the automatic control of the constant-tension coiling can be realized in the entire process.

Description

technical field [0001] The invention relates to the technical field of rubber machinery, in particular to a constant tension coiling device for a natural plain film forming machine. Background technique [0002] Natural plain film has the advantages of transparency, non-toxicity, no electrostatic adsorption, high temperature resistance and easy printing and dyeing. It is the packaging material for food, textiles, high-grade cigarettes and precision instruments and other daily and industrial products. [0003] The winding device zl201120175872.3 of the film forming machine includes a working table and two winding rollers erected on the working table and placed side by side. The two winding rollers are the main winding roller and the transitional winding roller. The rewinding roller is driven by a motor, and the top of the main rewinding roller is provided with a barrel clamping bracket. The take-up roller is a placement roller arranged side by side horizontally. It mainly s...
