Leftover material collecting device for knitted fabric production and using method thereof

The invention discloses a leftover material collecting device for knitted fabric production and a using method thereof. The leftover material collecting device comprises a collecting box and a vibrating mechanism; a hydraulic cylinder is installed at the top of the collecting box; the output end of the hydraulic cylinder extends into the collecting box and is fixedly connected with a pressing plate; the top of the pressing plate is fixedly connected with a baffle; one side of the baffle is fixedly connected with a transmission rod; teeth are fixedly connected to one side of the transmission rod; a feeding hopper is arranged on one side of the collecting box; and a vibration mechanism used for enabling the feeding hopper to vibrate is arranged on one side of the collecting box and located below the feeding hopper. Through the arrangement of the baffle, the hydraulic cylinder, the collecting box and other structures, leftover materials can still be put into the feeding hopper in a compression process, and the l
