NOVELTY - The utility model claims a box type negative-pressure roll-to-roll preparation device, comprising a box body, a pay-off mechanism, a take-up mechanism, a protective gas and a carbon source supply mechanism, a heating mechanism, a vacuum mechanism, a lifting mechanism and a control mechanism, the pay-off mechanism is set on the lifting mechanism, the lifting mechanism is set in the box body and is correspondingly set with the opening to drive the pay-off mechanism to enter and exit the heating box, a protective gas and a carbon source supply mechanism, a lifting mechanism, a take-up mechanism, a heating mechanism, the vacuum mechanism is respectively connected with the control mechanism to execute the action. The lifting mechanism can switch the pay-off mechanism between the heating mechanism and the non-heating mechanism, the temperature of the heating mechanism is maintained while the copper material is quickly changed, and the time and energy are saved. the object of the heating mechanism is not the single copper material but the whole coil of copper material, so that the penetration of the carbon source has enough time to grow graphene the surface of the copper material, which greatly improves the heating efficiency and the take-up speed, so as to improve the production and preparation efficiency.
