[0002] A battery refers to a cup, trough or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate an electric current. It is a device that can convert chemical energy into electrical energy. It has a positive electrode and a negative electrode. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy. Using batteries as an energy source can obtain a current with stable voltage, stable current, long-term stable power supply, and little external influence. In addition, the battery has a simple structure, is easy to carry, and is easy to charge and discharge. It is not affected by external climate and temperature, and has stable and reliable performance. It plays a great role in all aspects of modern social life.

[0003] During the battery production process, the paper roll needs to be loaded into the zinc shell, and the bottom paper needs to be installed at the bottom of the zinc shell to facilitate the subsequent addition of other materials.

[0104] By adopting a method of joint driving of multiple cams, after the cams are installed one by one as needed, all the mechanisms can be driven by one power source to achieve joint work. Compared with the existing electromechanical combined driving method, it not only has a simple structure, but also adopts a joint driving method, which can reduce the error rate, facilitate control, and reduce the manufacturing cost of the equipment.

[0105] A method for driving a linkage conveying device of a paper roll assembly machine comprises the following steps:

[0106] S1, start the first drive motor, drive the reducer to work through the first drive motor, and the driving sprocket on the reducer further drives the rotating shaft to rotate through the chain and the driven sprocket;

[0107] S2. The rotating shaft is provided with a first cam, a second cam, a third cam, a fourth cam and a fifth cam, which are driven by the rotation of the rotating shaft and are used as a driving force to further drive various mechanisms on the upper part.

[0108] The device realizes simultaneous and continuous driving by adopting a power output and different cam states. The purely mechanical driving method can avoid defects such as response delay, signal loss, control failure, etc. in electrical control, thereby achieving better driving consistency, better continuity, more convenient driving, and more convenient maintenance.
