A tobacco feeding machine is provided. Shredded tobacco falls from a tobacco feeding port to a charging tray, a long shaft rotates to enable a vibration device to drive the charging tray to vibrate, the shredded tobacco falls onto a tobacco feeding tray after vibrated on the charging tray, and the shredded tobacco on the tobacco feeding tray is absorbed away through a tobacco discharging port. A cylindrical support is arranged on a frame, the long shaft penetrates the cylindrical support, the charging tray is located above the long shaft and connected with the long shaft through the vibrationdevice, and the vibration device is further connected with the cylindrical support. The tobacco feeding tray is sleeved on the cylindrical support, a friction wheel motor drives the tobacco feeding tray to rotate by means of friction wheel transmission, and a belt wheel motor drives the long shaft to rotate and drives the vibration device to vibrate by means of belt transmission. The vibration device includes an eccentric shaft, an eccentric block and four composite springs. The eccentric shaft is located on the long shaft, and the eccentric distance between the eccentric shaft and the long shaft is e. The composition springs are vertically fixed in the place between a support round plate on the lower portion of the charging tray and the cylindrical support, a small hole is formed in the tobacco feeding tray, a sundry outlet is formed in the bottom of the frame, and sundries can fall off through the small hole in the tobacco feeding tray to be discharged through the sundry outlet.
