Description

Automatic barium sulfate packaging device and process Technical Field The invention relates to the technical field of material packaging machinery, in particular to an automatic barium sulfate packaging device and process. Background The bag feeding device of the packaging machine is one of key components in an automatic packaging production line and is responsible for accurately feeding packaging bags to a packaging station for filling, sealing and other operations. The bag feeding device of the packaging machine is generally composed of a bag feeding bracket, a clamping device and a bag conveying mechanism, wherein the bag feeding bracket provides support and stability for the whole bag feeding device, the clamping device is used for clamping packaging bags, and the bag conveying mechanism is responsible for conveying the packaging bags from a feed position to a packaging station. In practical application, the bag feeding device is applied to various bag feeding type packaging machines, and the packaging machines are generally used in automatic packaging production lines in the industries of food, medicine, chemical industry, daily chemicals and the like, so that the production efficiency is improved, the labor cost is reduced, and the product quality is guaranteed. The Chinese patent document with the authorized bulletin number of CN117902110B discloses a bag opening device for automatic packaging, which comprises a frame and a bag opening positioning mechanism, wherein the bag opening positioning mechanism is movably arranged at one end of the frame and is used for clamping a bag opening of a packaging bag, the bag opening positioning mechanism comprises clamping frames and a bag opening assembly, the bag opening assembly is used for driving the two clamping frames to be close to each other so as to adsorb the bag opening of the packaging bag or driving the two clamping frames to be away from each other so as to open the bag opening of the packaging bag, and after the bag opening of the packaging bag is opened, a material conveying opening of a filling mechanism can be opposite to the bag opening of the packaging bag, so that the purpose of filling materials is realized. After the packing bag is filled with products, the clamping frame can loosen the adsorption clamping of the opening of the packing bag, and the packing bag falls down due to gravity to realize discharging. However, the material inlet of the filling mechanism is generally in a circular tube structure, after being inserted into the bag opening of the packaging bag, the inner face of the packaging bag is difficult to be attached to the circular tube structure, so that an annular gap, namely an annular gap, is formed between the periphery of the circular tube structure and the bag opening, when the barium sulfate is filled, the barium sulfate can lift up and leak from the annular gap, thereby polluting the working environment, and in addition, the barium sulfate can be attached to the inner face of the bag opening, so that the subsequent sealing of the bag opening is affected. Disclosure of Invention The invention provides an automatic barium sulfate packaging device and a process, which aim to solve the problems that in the related art, powdery materials possibly leak to cause environmental pollution and adhere to the inner surface of a bag opening to influence sealing. The invention relates to an automatic barium sulfate packaging device which comprises a workbench, an electric turntable, a clamping mechanism, a filling mechanism and a locking unit, wherein the electric turntable is arranged on the workbench, the clamping mechanism is arranged on the electric turntable and used for clamping packaging bags, the filling mechanism is arranged on the workbench and is positioned beside the electric turntable and provided with two filling pipes which can downwards extend into the openings of the packaging bags, the locking unit is arranged on two sides of the filling pipes and comprises locking pieces and driving pieces, the locking pieces are assembled on the filling pipes in a sliding manner along the radial direction of the filling pipes, the locking pieces are provided with crescent-shaped locking grooves which are matched with the filling pipes, when the two locking pieces are mutually close, the locking grooves can clamp the openings of the packaging bags on the outer walls of the filling pipes, and the driving pieces are arranged on the filling pipes and are used for driving the locking pieces to slide. The packaging bag has the advantages that when the filling pipe starts to extend into the mouth of the packaging bag, the driving device is started to drive the two locking parts to be close to each other and tightly attached. Under the effect of locked groove, the sack of wrapping bag is by the buckling on the outer wall of filling tube steadily, form the parcel structure, thereby eliminate the annular clearance that probably produces be
