It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The automatic packaging box forming equipment is simple to operate, easy to adjust and has high production efficiency. It can save a lot of labor and labor costs, and can meet people's demand for packaging products as their living standards improve.

[0031] The automatic packaging box forming equipment in the related art cannot produce packaging boxes of different depths and sizes. The cartons need to be manually picked up during forming, which has poor practicality.

[0032] Based on this, in order to improve the problem in the related art that packaging boxes of different depths and sizes cannot be manufactured, the embodiments of the present application provide the following solution.

[0033] See also Figures 1 to 4 A packaging box automatic forming device includes a bracket 1, a pressing mechanism 3 and a mold mechanism 2. The mold mechanism 2 is used to make the size and shape of the carton, and the pressing mechanism 3 is used to extrude the cardboard into shape.

[0034] See also Figures 1 to 4, the mold mechanism 2 includes a main body 21, a sliding block 22, a first enclosing plate 23, a second enclosing plate 24, a sliding assembly 25, a support plate 26, and a buffer assembly 27. The buffer assembly 27 includes a return spring 271 and a connecting screw 272. The pressing mechanism 3 includes a fixed rod 31, a pressing plate 32, a hydraulic rod 33, a moving block 34, and a driving assembly 35. The driving assembly 35 includes a second motor 351, a second screw 352, and a slide rail 353.

[0035] The fixed rod 31 is welded to the bracket 1. The slide rail 353 is bolted to the fixed rod 31. The second motor 351 is threadedly connected to one end of the slide rail 353 away from the fixed rod 31. A third chute 341 and a threaded hole are formed in the moving block 34. The moving block 34 is slidably connected to the slide rail 353 through the third chute 341. One end of the second screw 352 is in transmission connection with the output shaft of the second motor 351. The other end of the second screw 352 is threadedly connected to the moving block 34 through the threaded hole. The hydraulic rod 33 is arranged on the moving block 34. The pressing plate 32 is bolted to the output end of the hydraulic rod 33. A rubber sleeve 36 is fixedly connected to the pressing plate 32;

[0036] The main body 21 is bolted to the bracket 1. A first chute 211 is formed in the main body 21. The sliding block 22 is slidably connected to the first chute 211 through the sliding assembly 25. A limiting groove 221 is formed in the sliding block 22. One end of the return spring 271 is fixedly connected to the sliding block 22. The support plate 26 is connected to the other end of the return spring 271. The connecting screw 272 is fixedly connected to the support plate 26 and is located in the return spring 271. The return spring 271 is located in the limiting groove 221. The first enclosing plate 23 is slidably connected to the sliding block 22. The second enclosing plate 24 is bolted to the support plate 26. An electric push rod 28 is bolted to the sliding block 22. The output end of the electric push rod 28 is in transmission connection with the first enclosing plate 23. A ejector rod 4 is further arranged on the main body 21, and the ejector rod 4 is located in the first chute 211;

[0037] With such a configuration, when the packaging box is pressed and formed, the packaging box cardboard is placed on the support plate 26. At this time, the second motor 351 is started, and the second motor 351 drives the second screw 352 to rotate, so that the moving block 34 moves, and then drives the hydraulic rod 33 and the pressing plate 32 to move above the support plate 26. When the pressing plate 32 moves above the support plate 26, the hydraulic rod 33 is started, so that the hydraulic rod 33 drives the pressing plate 32 to move downward, and the pressing plate 32 presses the packaging box cardboard into the limiting groove 221. At this time, the packaging box cardboard is folded 90 degrees under the action of the first enclosure 23 and the second enclosure 24, so that the packaging box cardboard forms a finished packaging box. After the packaging box is formed, the hydraulic rod 33 drives the pressing plate 32 to move upward, so that the pressing plate 32 is away from the limiting groove 221. At this time, the return spring 271 pushes the support plate 26 out, so that the formed packaging box moves out of the limiting groove 221.

[0038] The effect of such a configuration is that when a packaging box needs to be made from a longer or shorter packaging box cardboard, the electric push rod 28 drives the first enclosure 23 to move, thereby adjusting the distance between the two first enclosures 23 so that it can adapt to packaging box cardboards of different lengths. During the extrusion molding process of the packaging box cardboard, the rubber sleeve 36 can prevent the packaging box cardboard from being squeezed and damaged.

[0039] See also Figures 1 to 3 The sliding assembly 25 includes a first motor 251, a connecting shaft 252, a first screw rod 253 and a slider 254. The main body 21 is provided with a second slide groove 212. The first motor 251 is connected to the main body 21 by threads. The slider 254 is slidably connected in the second slide groove 212. A threaded hole is provided on the slider 254. One end of the first screw rod 253 is coaxially connected to the output end of the first motor 251. The other end of the first screw rod 253 is threadedly connected to the slider 254 through a threaded hole. The connecting shaft 252 is set on the sliding block 22. The sliding block 22 is rotatably connected to the slider 254 through the connecting shaft 252.

[0040] With such arrangement, when the cardboard is extruded and formed, the first motor 251 drives the first screw 253 to rotate, so that the sliding block 22 slides forward along the first slide groove 211. Afterwards, when the slider 254 drives the sliding block 22 to move above the ejection rod 4, the ejection rod 4 pushes the sliding block 22, so that the sliding block 22 rotates around the connecting shaft 252, thereby causing the formed packaging box on the support plate 26 to fall off, so that the carton is dumped;

[0041] The effect of such arrangement is that when the carton is extruded and formed, the carton can be automatically transported and dumped without manual operation, thus saving the labor of workers and reducing labor costs.

[0042] From the above, we can see that the working principle of this application is as follows:

[0043] When pressing and forming the packaging box, place the cardboard of the packaging box on the support plate 26. At this time, start the second motor 351. The second motor 351 drives the second screw rod 352 to rotate, causing the moving block 34 to move, and then driving the hydraulic rod 33 and the pressing plate 32 to move above the support plate 26. When the pressing plate 32 moves above the support plate 26, start the hydraulic rod 33, causing the hydraulic rod 33 to drive the pressing plate 32 to move downward. The pressing plate 32 presses the cardboard of the packaging box into the limiting groove 221. At this time, the cardboard of the packaging box folds 90 degrees under the action of the first surrounding plate 23 and the second surrounding plate 24, and then the cardboard of the packaging box forms a finished packaging box. After the packaging box is formed, the hydraulic rod 33 drives the pressing plate 32 to move upward, causing the pressing plate 32 to move away from the limiting groove 221. At this time, the reset spring 271 pushes the support plate 26 out, and then the formed packaging box moves out of the limiting groove 221;

[0044] When the cardboard is extruded and formed, the first motor 251 drives the first screw rod 253 to rotate, causing the sliding block 22 to slide forward along the first sliding groove 211. After that, when the slider 254 drives the sliding block 22 to move above the ejector rod 4, the ejector rod 4 pushes the sliding block 22, causing the sliding block 22 to rotate around the connecting shaft 252, and then the formed packaging box on the support plate 26 drops, causing the cardboard box to complete the dumping.

[0045] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
