Abstract

The invention provides a constant-tension unreeling device of a pillow type packaging machine. The constant-tension unreeling device comprises a base plate, a left supporting wheel, a right supportingwheel, a resisting mechanism, a first guide wheel, a second guide wheel, a balance weight mechanism and a drive wheel set, wherein the left supporting wheel is pivoted to the base plate; the right supporting wheel is pivoted to the base plate, and a film placement roller is supported jointly by the right supporting wheel and the left supporting wheel; the resisting mechanism is arranged on the base plate and abuts against the film placement roller; the first guide wheel is pivoted to the base plate, and the first guide wheel is located on the lower right of the right supporting wheel; the second guide wheel is pivoted to the base plate; the balance weight mechanism is movably arranged on the base plate and located between the second guide wheel and the first guide wheel; and the drive wheel set is arranged at the right end of the second guide wheel and is used for driving a composite film to move so that the film placement roller can carry out unreeling. According to the constant-tension unreeling device of the pillow type packaging machine, the tension of the composite film can be adjusted, and after being adjusted, the tension is in a constant value all the time.
