DETAILED DESCRIPTION

[0023] The present invention provides a long edge folding and bonding device for a face paperboard. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 The present invention provides a long-side folding and gluing device for face paperboard, comprising a frame 1, a plurality of transport rotating rollers 2 arranged on the frame 1 in a transversely extending manner, a transport rotating driving member for driving the plurality of transport rotating rollers 2 to rotate synchronously, two upper guide assemblies 3 arranged above the transport rotating rollers 2 and extending along the length direction of the frame 1, guide rods 4 arranged on the lower surfaces of the corresponding upper guide assemblies 3, and a gluing mechanism 11 arranged on the outer sides of the corresponding guide rods 4; the plurality of transport rotating rollers 2 are used to support and convey the bottom paperboard covered with the face paperboard to the downstream direction; the two upper guide assemblies 3 are both used to contact with the upper surface of the face paperboard, and the two gluing mechanisms 11 are respectively used to gluing the side walls of the corresponding long sides of the bottom paperboard after forming; the vertical distances from the two guide rods 4 to the transport rotating rollers 2 gradually decrease from the upstream to the downstream direction, the spacing between the two guide rods 4 is smaller than the width of the short side of the face paperboard, and the two guide rods 4 are respectively used to fold the long sides of the corresponding sides of the face paperboard toward the bottom paperboard, and make the folded edges formed by the face paperboard bonded with the glue on the side walls of the long sides of the bottom paperboard.

[0025] The previous station of the long edge folding and gluing station of the face paperboard is the short edge folding and gluing station of the face paperboard, that is, the short edge folding and gluing station of the face paperboard is used to glue the short edge of the face paperboard to the short edge of the bottom paperboard. In addition, glass is placed in the inner cavity of the formed bottom paperboard.

[0026] In actual application, the rotation of the transport rotating roller 2 provides kinetic energy for the carton to be glued on the long side of the face paperboard to be transported downstream. In the process of gradually transporting the carton downstream, the guide rods 4 located on both sides of the carton, due to the shape of the guide rods 4, make the parts on both sides of the long side of the face paperboard gradually fold downward under the external force of the corresponding guide rods 4. Since the purchased face paperboard will form pre-folding marks on both sides of the long side in advance, under the external force of the guide rods 4, the pre-folding marks can be easily folded downward and form a folding edge. Before the folding of the folding edge is completed, since the gluing mechanism 11 has already glued the side wall of the long side of the bottom paperboard, the long side of the face paperboard can be folded and glued at the same time under the continuous rotation of the transport rotating roller 2. In addition, the two upper guide components 3 are used to provide an installation position for the guide rods 4 on the one hand, and can contact the upper surface of the face paperboard on the other hand, and provide a certain amount of kinetic energy for the face paperboard to be transported downstream.

[0027] In the above device, the transport rotating roller 2 is provided to transport the carton downstream; the gluing mechanism 11 is provided to gluing the long side of the bottom paperboard; the guide rod 4 is provided so that the folding marks reserved on the long side of the surface paperboard can be gradually folded downward during the process of gradually transporting the surface paperboard downstream, and the glue on the long side of the bottom paperboard is used to achieve the bonding of the long side of the surface paperboard and the long side of the bottom paperboard; the upper guide assembly 3 is provided to provide an installation position for the guide rod 4 and provide kinetic energy for the carton to be transported downstream; the above device has a simple structure and a clever design.

[0028] See also Figure 3In some embodiments, the guide rod 4 includes a first connecting rod body 41, a bent rod body 42 and a second connecting rod body 43. The first connecting rod body 41 extends laterally and is fixedly connected to the two inner side walls of the upper guide assembly 3; the upper end of the bent rod body 42 is fixedly connected to the first connecting rod body 41, and the bent rod body 42 gradually tilts downward from the upstream to the downstream direction; the upper end of the second connecting rod body 43 is connected to the top inner wall of the upper guide assembly 3, and the lower end of the second connecting rod body 43 is connected to the bent rod body 42. In order to adapt to the shape of the upper guide frame 31, the first connecting rod body 41 is provided. Since the upper end of the bending rod body 42 is connected to the first connecting rod body 41, the lower end of the bending rod body 42 is a free end, and the bending rod body 42 also needs to provide downward pressure for the surface cardboard, so the lower end of the bending rod body 42 needs to be fixed, so the second connecting rod body 43 is provided to prevent the lower end of the bending rod body 42 from warping up during the process of pressing down on the opposite cardboard, thereby ensuring the downward pressure effect on the pre-folding mark of the opposite cardboard.

[0029] See also Figure 2 In some embodiments, the two upper guide assemblies 3 each include an upper guide frame 31 extending along the length direction of the frame 1 and having an opening at the bottom, a plurality of upper guide rollers 32 extending transversely and arranged on the upper guide frame 31, and an upper guide rotation driving member 33 for driving the plurality of upper guide rollers 32 to rotate synchronously; the upper end of the curved rod body 42 passes through the gap formed between two adjacent upper guide rollers 32 and is connected to the first connecting rod body 41; the upper end of the second connecting rod body 43 passes through the gap formed between two adjacent upper guide rollers 32 and is connected to the inside of the top of the upper guide frame 31. In this embodiment, the upper guide frame 31 is composed of side frames arranged symmetrically on the left and right, and a plurality of plates connecting the upper surfaces of the two side frames, which can meet the shape requirements of being hollow and having an opening at the bottom, and can also reduce the weight of the upper guide frame 31. In practical applications, the two ends of the first connecting rod body 41 are connected to the inner side walls of the two side frames, and the upper end of the second connecting rod body 43 is connected to the lower surface of any plate body. Specifically, the upper guide rotation drive member 33 can be composed of a guide rotation motor disposed on the upper surface of the plate body, a driving sprocket disposed on the output end of the guide rotation motor, a driven sprocket disposed on one end of a plurality of upper guide rollers 32 (the upper guide rotation drive member 33 in the figure indicates a driven sprocket), and a guide rotation chain wound between the driving sprocket and the driven sprocket.

The opposing drive motor drives the upper lead screw 352 to rotate, and since the upper lead screw 352 is provided with two opposite threads, the two upper nut seats 351 can move closer to or away from each other. The above arrangement enables the two upper guide frames 31 to move closer to or away from each other, so that the long edge folding and bonding device of the face paperboard can be adapted to the packaging of glass of different widths.

During the continuous conveying of the carton in the downstream direction, the corresponding side guide rollers 52 are driven to rotate synchronously, thereby reducing the friction of the carton during conveying. In addition, the lower lifting drive member can drive the plurality of side guide rollers 52 to rise or fall synchronously, so that the long edge folding and bonding device of the face paperboard can be adapted to the packaging of cartons / glass of different thicknesses.

In addition, the guide rails 55 and the sliders are provided, so that the two lower guide beams 51 can be close to or away from each other, so that they can cooperate with the two upper guide assemblies 3 located above to meet the bonding requirements of cartons of different widths.

[0037] In this schematic diagram, the upper lifting motor 341 and the lower lifting motor 541 are both hand wheels.
