The invention discloses a bag opening device for a packaging machine. The bag opening device comprises a bag opening mechanism and a bag containing platform used for containing packaging bags in a stacked manner. The bag opening mechanism comprises a supporting frame. Bag opening assemblies, bag pressing assemblies and a bag blowing assembly are arranged on the supporting frame. The bag opening assemblies are used for being inserted into the packaging bags with bag openings opened and supporting the packaging bags open. A pair of bag opening assemblies is arranged and symmetrically arranged on the supporting frame. A linear drive assembly is arranged in the supporting frame to drive the bag opening assemblies to move linearly. Each bag opening assembly comprises a control rod, and a pair of bag opening components capable of being mutually expanded is arranged on each control rod. Limiting rods are further arranged on the two sides of the supporting frame. A rotary control rod used for being in contact with the corresponding limiting rod to drive the corresponding control rod to rotate is arranged at the bottom of each control rod. The bag opening device for the packaging machine is high in bag opening success rate and production efficiency.
Description
technical field [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to a bag opening device for a packaging machine. Background technique [0002] In the packaging machine, it is necessary to open each bag through the bag opening mechanism, then push the items to be packed into the bag through the feeding mechanism, and then seal the bag to complete the packaging. Existing lending institutions mainly rely on vacuum suction cups to absorb one side of the packaging bag, and then open the packaging bag during the movement of the vacuum suction cups. A vacuum suction cup bag opening mechanism with patent number 201410405685.8 uses this principle, and the bag opening mechanism of this structure is easy to be unable to open the packaging bag efficiently when the vacuum suction cup is adsorbed, so the success rate of bag opening is not high, and Only relying on the vacuum suction cup to open the bag, the opening angle cannot be gua...
