Abstract

The utility model discloses a self-drive fine powder packaging machine. The self-drive fine powder packaging machine comprises a rack (1), a conveyer (3), a feeding device (2), a material returning device (5), a clamping device (6), a bag holder (8) and a PLC (10), wherein the feeding device (2), the material returning device (5), the clamping device (6), the bag holder (8) and the PLC (10) are installed on the rack (1), and the clamping device (6) comprises two clamping bars (601). The self-drive fine powder packaging machine has the advantages that a weight sensor is arranged on the bag holder and used for calculating the weight of materials; when fine powder in a bag reaches the set weight, the bag opening is clamped immediately by the clamping device, fine powder will not enter the bag any more, and thus the accuracy of the weight of fine powder in the bag is guaranteed; the clamping device is further used for conveying material bags to a conveyer belt below, the material bags are prevented from directly falling onto the conveyer belt, and thus materials are prevented from vibrating and scattering.
