Description

Technical Field

[0001] The utility model relates to the field of carton production equipment, in particular to a carton nailing deviation rectifying and positioning device. Background Technique

[0002] Cartons are usually used as packages for goods or outer protective layers for items, and are divided into corrugated cartons, single-layer cardboard boxes, etc. according to different materials. The production process of cartons successively includes: die-cutting, printing, folding and stapling of cardboard. Usually, a folding mechanism is used to fold the cardboard. After folding, the cardboard forms a double-layer structure. The lower layer is a plate-like structure without seams, and the upper layer is composed of two symmetric plate-like structures, and there is a seam between the two plate-like structures. After folding, a carton stapler is used to staple the seam between the two plate-like structures. The principle of the carton stapler is the same as that of an ordinary stapler.

[0003] However, during the stapling process, the nails are likely to penetrate through the seam of the cardboard and staple the entire cardboard, causing damage to the cardboard, reducing the production reliability and the yield rate; moreover, before the double-layer cardboard is fed into the carton stapler after folding, it often deflects and cannot be accurately positioned, resulting in deviation of the stapling position, reducing the stapling effect and the stapling quality of the cardboard. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a carton nailing deviation rectifying and positioning device that improves production reliability, yield rate, positioning accuracy and stapling quality.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 6, the present utility model provides a technical solution: a nail box deviation correction and positioning device, including a nail - driving gasket 1 and a frame 2. A first gantry 3 is connected to the upper side of the frame 2. The nail - driving gasket 1 includes an arc - shaped portion 101 and a straight - bar portion 102 connected to the rear end of the arc - shaped portion 101. The front end of the arc - shaped portion 101 is fixed to the first gantry 3. Conveyor mechanisms 4 are symmetrically arranged on both sides of the straight - bar portion 102, and a first cylinder 5 is arranged above it. The output end of the first cylinder 5 is connected to a mounting frame 6. The bottom of the mounting frame 6 is rotatably connected to a material - pushing and positioning plate 7. A second cylinder 8 is arranged below the straight - bar portion 102. The top output end of the second cylinder 8 is connected to a material - blocking and positioning plate 9. The material - blocking and positioning plate 9 is arranged at the rear side of the material - pushing and positioning plate 7;

[0027] The cardboard is conveyed under the nail - driving gasket 1, and after being conveyed to a folding mechanism for folding to form a double - layer cardboard 27, the nail - driving gasket is placed between the upper - layer cardboard and the lower - layer cardboard of the double - layer cardboard 27, and the nail - driving gasket is placed under the joint of the upper - layer cardboard. Then the double - layer cardboard 27 is conveyed between the two conveyor mechanisms 4, and the conveyor mechanisms 4 continue to convey the double - layer cardboard 27. At this time, the rear side of the double - layer cardboard 27 pushes the material - pushing and positioning plate 7, causing the material - pushing and positioning plate 7 to rotate upwards relative to the mounting frame 6. During the conveying process of the double - layer cardboard 27, its upper side supports the material - pushing and positioning plate 7. When the double - layer cardboard 27 is conveyed a certain distance, the double - layer cardboard 27 is blocked by the material - blocking and positioning plate 9. At the same time, the material - pushing and positioning plate 7 loses the support of the double - layer cardboard 27. At this time, under the action of gravity, the material - pushing and positioning plate 7 rotates in the opposite direction relative to the mounting frame 6 to form a reset. Then the first cylinder 5 drives the mounting frame 6 to move backward, driving the material - pushing and positioning plate 7 to push the double - layer cardboard 27 towards the material - blocking and positioning plate 9, thereby forming a positioning, pressing and straightening the skewed double - layer cardboard 27, improving the positioning accuracy and the nailing quality. After positioning, the second cylinder 8 drives the material - blocking and positioning plate 9 to descend, enabling the double - layer cardboard 27 to continue to be conveyed and conveyed to a nail - box machine for nailing.

The rear side of the rotating block 21 is fixedly connected to the pushing and positioning plate 7, and the front side of the pushing and positioning plate 7 is movably abutted against the U-shaped block 602;

[0039] The purpose is that when the double-layer cardboard 27 pushes the pushing and positioning plate 7, the rotating block 21 rotates relative to the U-shaped block 602, causing the pushing and positioning plate 7 to turn upwards. When the pushing and positioning plate 7 loses the support of the double-layer cardboard 27, under the action of gravity, the rotating block 21 rotates in the opposite direction relative to the U-shaped block 602, causing the pushing and positioning plate 7 to reset. And when the pushing and positioning plate 7 pushes the double-layer cardboard 27, the rear side of the U-shaped block 602 abuts against the front side of the pushing and positioning plate 7, improving the stability of the pushing structure.

At this time, the first rotary feeding belt 22 abuts against the upper side of the double-layer cardboard 27, and the second rotary feeding belt 25 abuts against the lower side of the double-layer cardboard 27 to prevent the double-layer cardboard 27 from warping. After the double-layer cardboard 27 is positioned, the third air cylinder 24 drives the lifting frame 23 to descend, driving the first rotary feeding belt 22 to descend, and then the first rotary feeding belt 22 and the second rotary feeding belt 25 clamp the double-layer cardboard 27 to prevent the double-layer cardboard 27 from shifting. Then the second air cylinder 8 drives the material blocking and positioning plate 9 to descend, and by driving the first rotary feeding belt 22 and the second rotary feeding belt 25 to rotate, the double-layer cardboard 27 is conveyed to the box nailing station with a precise stroke.

[0042] In order to conveniently improve the smoothness of the conveyance of the double-layer cardboard 27, in this embodiment, preferably, two first rotary feeding belts 22 are symmetrically arranged with the vertical plane where the straight strip portion 102 is located as the center, and two second rotary feeding belts 25 are symmetrically arranged with the vertical plane where the straight strip portion 102 is located as the center.

[0043] In order to facilitate improving the accuracy of the conveying stroke of the double-layer cardboard 27 and enhancing the smoothness of conveying, in this embodiment, preferably, the conveying mechanism 4 includes a third rotary feeding belt 401, a first roller group 402, and a second roller group 403.

When the third rotary feeding belt 401 rotates, it drives the double-layer cardboard 27 to move and be conveyed. By the first roller group 402 abutting against the lower side of the double-layer cardboard 27, the smoothness of the moving conveyance of the double-layer cardboard 27 is improved. By the second roller group 403 abutting against the edge of the double-layer cardboard 27, a limit is formed to prevent the double-layer cardboard 27 from shifting, and the accuracy of the conveying stroke of the double-layer cardboard 27 is improved.

At this time, the rear side of the double-layer cardboard 27 pushes the material pushing and positioning plate 7, causing the material pushing and positioning plate 7 to rotate upwards relative to the mounting frame 6. During the conveying process of the double-layer cardboard 27, its upper side supports the material pushing and positioning plate 7. When the double-layer cardboard 27 is conveyed a certain distance, the double-layer cardboard 27 is blocked by the material blocking and positioning plate 9. At the same time, the material pushing and positioning plate 7 loses the support of the double-layer cardboard 27. At this time, under the action of gravity, the material pushing and positioning plate 7 rotates reversely relative to the mounting frame 6 to form a reset. Then, the first cylinder 5 drives the mounting frame 6 to move backward, driving the material pushing and positioning plate 7 to push the double-layer cardboard 27 towards the material blocking and positioning plate 9, thereby forming a positioning, pressing and straightening the skewed double-layer cardboard 27, improving the positioning accuracy and the nailing quality. After positioning, the second cylinder 8 drives the material blocking and positioning plate 9 to descend, enabling the double-layer cardboard 27 to continue to be conveyed and conveyed to the nailing machine for nailing.
