Technical Field

[0001] This utility model relates to the field of cardboard box folding technology, specifically a folding device for cardboard box packaging. Background Technology

[0002] From the factory to the consumer, goods go through multiple stages such as transportation, warehousing, sorting, and handling. Through structural design and material characteristics, cardboard boxes provide all-round protection for goods, which is their most basic and crucial function.

[0003] Chinese patent discloses a high-efficiency cardboard box folding device for cardboard box processing, publication number CN222495615U. It includes a support rod, with a folding platform fixedly connected to the top of the support rod. A rotating folding mechanism is provided on the top of the folding platform, and a pressing mechanism is provided at the back end of the folding platform. The rotating folding mechanism includes a rotating component and a folding component. The rotating component is located in the middle of the top of the folding platform and on the front of the top of the folding platform. The rotating component includes a first motor, which is fixedly connected to the top of the folding platform. A first worm gear is fixedly connected to the back end of the first motor, and a first worm wheel meshes with the left side of the first worm gear. When the cardboard box needs to be rotated, the pressing plate presses the cardboard box, activating the first motor. The first motor drives the first worm wheel to rotate via the first worm gear, which in turn drives the rotating plate to rotate via a linkage rod, thus rotating the cardboard box.

[0004] However, it still has the following drawbacks: the device folds the carton by starting a second motor to drive a rotating plate, but folding the four sides of the carton sequentially is inefficient. Therefore, we propose a folding device for carton packaging to solve this problem. Utility Model Content

This folding device for cardboard packaging comprises a placement plate, a limiting plate, a mounting cylinder, a folding plate, a bracket, a slide rail, a mounting base, a first positioning bolt, a hydraulic rod, a pressure plate, an adjusting plate, a limiting slide plate, and a second positioning bolt. The cross-shaped cardboard box is placed on the placement plate, and the hydraulic rod is extended to allow the pressure plate to move downwards against the cardboard and the placement plate. The folding plate then pushes the cardboard to fold, thus securing the edges of the cardboard. By rotating the first positioning bolt, the position of the folding plate is adjusted to align its edge with the cardboard's crease. Rotating the second positioning bolt aligns the edge of the adjusting plate with the cardboard's crease, allowing for the folding of cardboard boxes of different sizes.

By setting spring 214, it is convenient to support limiting plate 212 and to facilitate the upward reset of plate 211.

[0030] The inner wall of the folding plate 215 is fixedly connected to the outer surface of the slide rail 217, and the mounting base 218 is slidably sleeved on the outer surface of the slide rail 217.

[0031] The thread on the outer surface of the top of the first positioning bolt 219 penetrates the bottom surface of the mounting base 218 and makes contact with the bottom surface of the slide rail 217;

[0032] The mounting bracket 3 is equipped with a power unit 22;

[0033] The power unit 22 includes a limiting rod 223 and a sleeve 224. The top surface of the limiting rod 223 is fixedly connected to the inner wall of the mounting bracket 3. The sleeve 224 is slidably sleeved on the outer surface of the limiting rod 223. The power unit 22 also includes a hydraulic rod 221, a pressure plate 222, a push plate 225, an adjusting plate 226, a limiting slide plate 227, and a second positioning bolt 228.

[0034] A limiting groove is provided on the outer surface of the pressure plate 222. The outer surface of the limiting slide plate 227 extends into the interior of the pressure plate 222 and slides in connection with the inner wall of the pressure plate 222. The outer surface of the limiting slide plate 227 is fixedly connected to the outer surface of the adjusting plate 226. The outer surface of the hydraulic rod 221 is fixedly penetrates the inner wall of the mounting frame 3 and extends to the top of the mounting frame 3. The bottom surface of the output rod of the hydraulic rod 221 is fixedly connected to the top surface of the pressure plate 222.

[0035] The threaded outer surface of the bottom end of the second positioning bolt 228 penetrates the top surface of the pressure plate 222 and presses against the top surface of the limiting slide plate 227. By setting up the placement plate 211, limiting plate 212, mounting cylinder 213, folding plate 215, bracket 216, slide rail 217, mounting base 218, first positioning bolt 219, hydraulic rod 221, pressure plate 222, adjusting plate 226, limiting slide plate 227 and second positioning bolt 228, the cross-shaped cardboard box is placed on the placement plate 211. The hydraulic rod 221 is extended, so that when the pressure plate 222 moves downward against the cardboard and the placement plate 211, the folding plate 215 pushes the cardboard to flip and fold, thus fixing the edge of the cardboard. By rotating the first positioning bolt 219, the position of the folding plate 215 is adjusted, and the edge of the folding plate 215 is aligned with the cardboard crease. By rotating the second positioning bolt 228, the edge of the adjusting plate 226 is aligned with the cardboard crease, and cardboard of different sizes can be folded.

By setting the limiting rod 223, the sleeve 224 and the push plate 225, when the adjusting plate 226 moves, it drives the sleeve 224 to move horizontally in sync. When the hydraulic rod 221 shortens, the push plate 225 pushes the carton down.

[0037] When folding the same type of cardboard, place the cross-shaped cardboard on the top surface of the placement plate 211, control the extension of the hydraulic rod 221, and the output rod of the hydraulic rod 221 drives the pressure plate 222, the limiting slide plate 227 and the adjusting plate 226 to move downward, so that the limiting slide plate 227 and the pressure plate 222 press down on the cardboard. At the same time, the placement plate 211 moves downward, so that the folding plate 215 pushes the cardboard around the perimeter to fold. At this time, the carton is fitted on the outside of the four adjusting plates 226 and the folding plate 215 is fitted on the outside of the carton, so that the four sides of the carton can be connected and fixed. Then, control the shortening of the hydraulic rod 221, so that the push plate 225 pushes the carton fitted on the outside of the adjusting plate 226 down.

[0038] When folding different types of cardboard, rotate the first positioning bolt 219 to align the edge of the folding plate 215 with the cardboard crease, and rotate the second positioning bolt 228 to align the edge of the adjusting plate 226 with the cardboard crease. This allows you to fold cardboard of different sizes.
