The invention discloses a material finishing and conveying system. The material finishing and conveying system comprises a rack, a power device, a material finishing and conveying device and sliding groove devices. The sliding groove devices are connected with discharging ports of capacitor material rolling machines corresponding to the sliding groove devices in a butt-joint mode, and the power device, the sliding groove devices and the material finishing and conveying device are all installed on the rack; the material finishing and conveying device comprises a conveying line, a conveying linebaffle adjusting mechanism and a friction plate, the friction plate is arranged in the conveying direction of the conveying line, the conveying line baffle adjusting mechanism comprises a baffle, thebaffle is arranged in the conveying direction of the conveying line, and the baffle and the friction plate are arranged in a spaced mode; and the rack comprises a supporting foot unit, a support unitand a connecting plate used for adjusting the angle and the height between the supporting foot unit and the support unit, and the supporting foot unit is connected with the support unit through the connecting plate. According to the material finishing and conveying system, the two or more than two capacitor material rolling machines can be connected with a hole plugging machine in a seamless butt-joint mode through the material finishing and conveying system, and the automated and unmanned intermediate process is achieved.
