Description

Technical Field

[0001] The utility model relates to the technical field of carton packaging equipment, in particular to a carton paperboard 180-degree packing machine. Background Art

[0002] After the cartons are processed by the forming equipment, they are stacked in sequence at the end of the forming equipment. The stacked cartons are transported to the subsequent box consolidation and alignment equipment via a conveyor device. The box consolidation and alignment equipment aligns the stacked cartons, and then the aligned cartons are packaged by a baler. The packaged bundles of cartons are stacked in sequence after transportation for palletizing. However, after some cartons are formed, the front and back sides of the flat-laid state are asymmetrical structures, that is, the flat-laid carton cardboard has one side thicker than the other side due to its structural requirements. In this way, the stacked cartons will also have one side higher than the other. When the bundled cartons are palletized after packaging, due to the different heights of the two sides of the stacked cartons, as the height of the screw stacking of the bundled cartons increases, the stacked bundles of cartons will gradually deviate to one side, resulting in the cartons tipping over. This brings great inconvenience to the palletizing work. Utility Model Content

[0003] The purpose of the utility model is to avoid the shortcomings of the existing technology and provide a 180-degree carton board turning machine, thereby effectively solving the shortcomings of the existing technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a 180-degree carton and cardboard flipping machine, comprising a flip plate seat arranged on a carton conveying mechanism, a plurality of clamping arms are symmetrically arranged on both sides of the flip plate seat, and the clamping arms can open and close synchronously. The clamping arms are arranged above the conveyor belt on the carton conveying mechanism and each clamping arm is located in the gap between each conveyor belt.

[0005] Furthermore, two driving cylinders are provided on the flip plate seat at positions corresponding to each set of symmetrical clamping arms, the piston rods of the two driving cylinders are oriented in opposite directions, and the symmetrical clamping arms on both sides are fixedly connected to the piston rods of the two driving cylinders respectively.

[0006] Furthermore, two driving cylinders for driving the clamping arms on both sides to move synchronously are arranged in a stacked manner.

[0007] Furthermore, rotating seats are provided on the side plates on both sides of the carton conveying mechanism, and the rotating seat on one side is driven to rotate by a motor. Mounting plates are provided at both ends of the flip plate seat, and the mounting plates are fixedly connected to the rotating shafts of the rotating seats on both sides.

[0008] Furthermore, the two symmetrical clamping arms are respectively provided with a plurality of protective pads on one side opposite to each other.

[0009] Furthermore, the protective pad includes a base plate fixedly connected to the clamping arm, a pad is provided on a side of the base plate away from the clamping arm, and the base plate is fixedly connected to the clamping arm via a dismantling pin.

[0010] Furthermore, the disassembly pin includes a pin rod fixedly connected to the base plate, a pin hole adapted to the pin rod is provided on the clamping arm, and one end of the pin rod inserted into the pin hole is provided with a convex head extending toward the outside of the clamping arm, and a retaining ring is sleeved on the convex head, the outer diameter of the retaining ring is the same as the diameter of the pin rod and the inner diameter thereof is larger than the diameter of the convex head, and an adjustable pin cap is provided at the end of the convex head, and the pin cap tightens the retaining ring on the convex head.

[0011] Furthermore, one end of the pin cap connected to the convex head is provided with a threaded rod, the end of the convex head is provided with a threaded hole adapted to the threaded rod, and the pin cap is threadedly connected to the convex head.

[0012] Furthermore, the pad is made of rubber.

[0013] The above technical solution of the present invention has the following beneficial effects: the bag turning machine of the present invention is arranged between the box gathering and aligning equipment and the baling machine, and realizes the turning operation of the stacked cartons by controlling the reciprocating rotation of its turning plate seat and the opening and closing of the clamping arm. After the turning, the front and back directions of the cardboards of the stacked cartons are reversed. In this way, when the stacking operation is carried out after packaging, the thicker side of the upper carton stack will be pressed on the thinner side of the lower carton stack. In this way, when the stacked cartons are stacked, the height difference between the two sides of the stacked cartons can be compensated, thereby ensuring the stable placement of the stacked cartons and preventing the cartons from tipping over to one side, which brings great convenience to production.
