Description

Device for folding package box Technical Field The utility model relates to a device for folding a packaging box. Background The paper package box is used in various industries, and in the forming process, some paper package boxes are formed into semi-finished products with open tops by unfolded paper boards, and then a plane paper cover is adhered to the open positions, so that the package box finished products are formed. In the existing manufacturing process from semi-finished product to finished product, the periphery of the top opening of the semi-finished product is basically manually turned outwards to form a folded edge, then the periphery of the plane paper cover is adhered to the folded edge of the top opening of the semi-finished product in a hot melt adhesion mode, the efficiency of manual folding is low, the forming efficiency of the packaging box is low, the quality of the folded edge cannot be kept consistent, defective products of the packaging box often occur, and the cost of the packaging box is increased. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide a device for folding a packaging box. According to one aspect of the present utility model there is provided an apparatus for creasing a package, comprising: A driving part; a spreading part for spreading the periphery of the opening of the packing box; A folding part for folding the periphery of the opening of the packing box outwards, a spreading part arranged on the folding part, a driving part for driving the folding part to move up and down, and The bottom support is used for placing the packing box and is positioned below the opening part and the flanging part. According to the device disclosed by the utility model, the semi-finished packing box with the top opening is placed on the bottom support, the driving part drives the flanging part to move towards the bottom support, the flanging part drives the opening part to synchronously move towards the bottom support, the opening part firstly opens the periphery of the opening of the packing box outwards, then the flanging part turns the periphery of the opening of the packing box outwards, the flanging part processes the periphery of the opening of the packing box into a flanging shape under the supporting effect of the bottom support, and the periphery of the plane paper cover can be adhered to the flanging of the top opening of the packing box in a hot-melt adhesion manner. Preferably, the flanging part comprises a substrate and a plurality of flanging rods, the upper ends of the flanging rods are arranged on the edge of the substrate, the opening part is positioned below the substrate, a guide rod is arranged at the top of the opening part and inserted into the substrate, a spring is sleeved on the guide rod, one end of the spring is abutted to the bottom of the substrate, the other end of the spring is abutted to the opening part, and the driving part drives the substrate to move up and down. Therefore, the semi-finished packaging box with the top opening is placed on the bottom support, the driving part drives the substrate to move towards the bottom support, the substrate drives the opening part to synchronously move towards the bottom support through the guide rod, the opening part opens the periphery of the opening of the packaging box outwards, the guide rod moves upwards in the substrate along with the continuous movement of the substrate towards the bottom support, the spring on the guide rod is compressed, the relative distance between the opening part and the substrate is reduced, then the edge folding rod on the substrate turns the periphery of the opening of the packaging box outwards, the bottom of the edge folding rod processes the periphery of the opening of the packaging box into an edge folding shape under the supporting effect of the bottom support, after the processing is finished, the driving part drives the substrate to move towards the direction far away from the bottom support, and the opening part resets under the restoring force of the spring so as to be ready for the next processing.
