Side-placed type top film laying machine

Disclosed is a side-placed type top film laying machine. The side-placed type top film laying machine consists of two large parts, namely a film placing frame and a top film laying mechanism, wherein the film laying frame and the top film laying machine are both evenly distributed on one side of a conveying line. The film placing frame consists of a film coil laying machine frame, a film coil central spindle, a film storage device, a thin film welding device, and a film coil driving device. The top film laying mechanism consists of a machine frame, a drive device, a film selecting device, and a film clamping device. Automatic switchover of package films with different standards is achieved by using an air cylinder to drive. A decelerator with an encoder is used to conduct film placing driving so as to enable film placing displacement to be precise. The air cylinder is used for driving a film clamp to conduct film clamping so as to enable the film clamping to stable and reliable. A method of driving wheels is
