Problems solved by technology
Roll plate laminating printing machine mainly includes unwinding device, leveling device, laminating device, printing unit and rewinding device. In the past, unwinding device and rewinding device were driven by a motor through a rewinding and unwinding roller with a large diameter. Constant tension force rewinding and unwinding, the power is provided by the motor, so the power requirement for the motor is relatively large, and its structure is relatively complicated, taking up a large space, which has certain limitations for some users with small venues

The invention relates to a shaftless frictional energy-saving coiling and unwinding device, which includes a base, a winding core tube, a motor and a constant pressure cylinder installed on the base, and a main friction power connected by a synchronous belt is installed on the base. The roller and the slave friction power roller, the main friction power roller is directly connected with the motor, the winding core tube is placed above the main friction power roller and the slave friction power roller, and a pressing arm is connected to the output end of the constant pressure cylinder. One end of the pressing arm is hinged with the base, and the other end is provided with a pressing roller located in the winding core tube to provide downward pressure, and a pressing roller and a steering roller closely attached to the secondary friction power roller are also arranged on the base. Compared with the former, the power required by the present invention is greatly reduced by directly using the motor to drive the roll core of the coiled plate. At the same time, the motor controls the constant speed operation of the friction power roller to ensure the synchronous operation of the subsequent equipment. Can achieve the purpose of energy saving.
Description
technical field [0001] The invention relates to a coiling and unwinding device, in particular to a shaftless friction energy-saving coiling and unwinding machine for a wide-width coiled and laminated printing machine. It belongs to the technical field of compound film printing. Background technique [0002] The decorative printing of traditional metal sheets is done one by one through priming, white coating, multi-color overprinting and glazing. Adopting this method not only has complex procedures, but also requires large equipment investment, low efficiency and high cost, and the whitening process causes serious environmental pollution. In recent years, a composite film decoration process has been introduced on the market, which has made great progress in environmental protection and energy saving. Roll plate laminating printing machine mainly includes unwinding device, leveling device, laminating device, printing unit and rewinding device. In the past, unwinding device a...
