[0071] Attachment Figure 1 The paper box 200 described in this application is in a state before being folded. Figure 2 This is the state of the paper box 200 described in this application after folding and forming. Figure 1 and attached Figure 2As shown, the carton 200 includes two front panels 201 and two side panels 202, the two front panels 201 are arranged opposite to each other, the two side panels 202 are arranged opposite to each other, the two sides of the two front panels 201 are respectively connected to the two side panels 202, one end of each front panel 201 is connected to an inner end panel 203 and an outer end panel 204 connected to the inner end panel 203, and both ends of each side panel 202 are provided with side ears 205. When the carton 200 is folded, the two side ears 205 at one end of the carton 200 are bent in a direction toward each other, the inner end panel 203 of the carton 200 approaches the corresponding two side ears 205, and closes one end of the carton 200. The outer end panel 204 of the carton 200 is inserted between the two front panels 201, thereby realizing the folding of the carton 200. When folding the carton 200, one end of the carton 200 is usually folded so that items can be loaded from the other end of the carton 200.

[0072] See also Figure 3 and Figure 4 The automatic carton folding machine 100 provided in this application is now described. The automatic carton folding machine 100 is used to fold carton 200. The automatic carton folding machine 100 includes a frame 10, a loading mechanism 20, a folding mechanism 30, a stacking mechanism 50, and a unloading mechanism 40. The loading mechanism 20, the folding mechanism 30, the stacking mechanism 50, and the unloading mechanism 40 are all mounted on the frame 10. The loading mechanism 20 is used to stack multiple carton 200 and also to transport carton 200. The folding mechanism 30 is used to fold one end of the carton 200 transported by the loading mechanism 20 into a folded shape. That is, the loading mechanism 20 transports the carton 200 to the folding mechanism 30. The folding mechanism 30 is used to fold the side ear 205, the inner end panel 203 and the outer end panel 204 at one end of the paper box 200 conveyed by the feeding mechanism 20, and the unloading mechanism 40 cooperates with the folding mechanism 30 to open the paper box 200 so that the folding mechanism 30 can fold one end of the paper box 200, and the unloading mechanism 40 is also used to transfer the folded paper box 200 from the folding mechanism 30 to the stacking mechanism 50, and the stacking mechanism 50 is used to stack the folded paper boxes 200, that is, the folding mechanism 30 first cooperates with the unloading mechanism 40 to open the paper box 200, and then the folding mechanism 30 folds one end of the opened paper box 200 into shape, and the folded paper box 200 is transferred from the unloading mechanism 40 to the stacking mechanism 50 for stacking. The automatic paper box folding machine 100 can realize automatic folding of the paper box 200. When the paper box 200 has the characteristics of hard material, large area and small thickness, the folding efficiency of the paper box 200 can be greatly improved.

[0073] Compared with the prior art, the automatic carton folding machine 100 provided by the present application utilizes a loading mechanism 20 to stack carton 200 and transfer the carton 200 to a folding mechanism 30. The unloading mechanism 40 cooperates with the folding mechanism 30 to open the carton 200 so that the folding mechanism 30 folds one end of the carton 200 into shape. The unloading mechanism 40 then transfers the folded carton 200 to a stacking mechanism 50 for stacking. When the carton 200 is made of a relatively hard material, has a large area, or is thin, the automatic carton folding machine 100 can realize automated folding of the carton 200, thereby improving the folding efficiency of carton 200 with characteristics such as a relatively hard material, a large area, and a thin thickness. In addition, the automatic carton folding machine 100 has a simple structure and is easy to install and operate.

[0074] In one embodiment, see Figures 3 to 5 The folding mechanism 30 includes a first suction cup assembly 31, a first folding mechanism 32, a second folding mechanism 33 and a third folding mechanism 34. The first suction cup assembly 31 is used to suck and fix a front panel 201 of the carton 200 to position the carton 200. The first folding mechanism 32 is used to fold the two side ears 205 at one end of the carton 200 in a direction toward each other. The second folding mechanism 33 is used to bend the outer end panel 204 corresponding to the carton 200 in the direction of the bent side ears 205. The third folding mechanism 34 is used to bend the inner end panel 203 corresponding to the carton 200 in the direction of the bent side ears 205 to close one end of the carton 200 and make the corresponding outer The end panel 204 is inserted between the two front panels 201, that is, when the folding mechanism 30 performs the folding operation, the first suction cup assembly 31 first sucks one front panel 201 of the carton 200 to position the carton 200, then the first folding mechanism 32 first folds the two side ears 205 at one end of the carton 200, and the second folding mechanism 33 then bends the outer end panel 204 corresponding to the carton 200, and finally the third folding mechanism 34 bends the inner end panel 203 corresponding to the carton 200, and at the same time, the outer end panel 204 of the carton 200 is inserted between the two front panels 201 to close one end of the carton 200, thereby completing the folding of one end of the carton 200.

[0075] In one embodiment, see Figure 5 The first folding mechanism 32 includes two first driving members 321 and two push plates 322. The two first driving members 321 are respectively arranged on both sides of the first suction cup assembly 31. The two push plates 322 correspond to the two first driving members 321 one by one. The first driving member 321 drives the corresponding push plate 322 to push the side ear 205 corresponding to the paper box 200 on the first suction cup assembly 31 to move to bend the side ear 205. When folding the side ear 205, the first driving member 321 drives the push plate 322 to abut against the side ear 205 and drive the side ear 205 to move, thereby realizing the folding of the side ear 205.

[0076] In one embodiment, see Figure 5 The push plate 322 includes a first plate 3221 connected to the first driving member 321 and a second plate 3222 for contacting the side ears 205. The first plate 3221 and the second plate 3222 are connected, and the angle between the first plate 3221 and the second plate 3222 is less than or equal to 90 degrees. When folding the two side ears 205, the first driving member 321 drives the first plate 3221 closer to the side ears 205, thereby causing the second plate 3222 to contact the side ears 205. As the first driving member 321 drives the first plate 3221 to move further, because the angle between the first plate 3221 and the second plate 3222 is less than or equal to 90 degrees, the second plate 3222 causes the side ears 205 to bend, thereby causing the two side ears 205 to fold toward each other. It is understood that the first driving member 321 can be a linear actuator such as a cylinder or a linear module.

[0077] In one embodiment, see Figure 5 The second folding mechanism 33 includes a second suction cup assembly 331 and a rotating drive member 332. The second suction cup assembly 331 is used to suck the outer end panel 204 corresponding to the paper box 200, and the rotating drive member 332 is used to drive the second suction cup assembly 331 to rotate so that the second suction cup assembly 331 bends the outer end panel 204 toward the direction of the bent side ear 205, so that when the paper box 200 is folded, the outer end panel 204 and the inner end panel 203 can form a certain angle so that the outer end panel 204 can be inserted between the two front panels 201.

[0078] In one embodiment, see Figure 5 The second folding mechanism 33 further includes a second driving member 333, which is used to drive the second suction cup assembly 331 toward or away from the outer end panel 204. The second driving member 333 is mounted on the rotating driving member 332, and the second suction cup assembly 331 is connected to the movable end of the second driving member 333. When the second folding mechanism 33 bends the outer end panel 204 of the paper box 200, the second driving member 333 first drives the second suction cup assembly 331 toward the outer end panel 204 to suck the outer end panel 204. The rotating driving member 332 then drives the second driving member 333 to rotate, thereby driving the second suction cup assembly 331 to rotate to bend the outer end panel 204.

[0079] In one embodiment, see Figure 5The rotating driving member 332 includes a rotating cylinder 3321 and a swing arm 3322. The swing arm 3322 is connected to the second driving member 333. The rotating cylinder 3321 is used to drive the swing arm 3322 to rotate. The rotating driving member 332 is started, and the rotating driving member 332 drives the swing arm 3322 to rotate, thereby driving the second suction cup assembly 331 to rotate to bend the outer end panel 204 of the paper box 200.

[0080] It can be understood that the second driving member 333 can be a linear drive such as a cylinder, a linear module, etc.

[0081] In one embodiment, see Figure 5 The third folding mechanism 34 includes a third suction cup assembly 341 and a driving mechanism 342. The third suction cup assembly 341 is used to suck the inner end panel 203 corresponding to the paper box 200. The driving mechanism 342 is used to drive the third suction cup assembly 341 to rotate so that the third suction cup assembly 341 bends the inner end panel 203 toward the bent side ear 205, thereby closing one end of the paper box 200 and inserting the outer end panel 204 between the two front panels 201 to achieve folding of the paper box 200.

[0082] In one embodiment, see Figure 5 The drive mechanism 342 includes a drive motor 3421, a pulley assembly 3422, a bearing support 3423, and a first connecting rod 3424. The pulley assembly 3422 is connected to one end of the drive motor 3421 and the bearing support 3423, respectively. The other end of the bearing support 3423 is connected to the first connecting rod 3424. The third suction cup assembly 341 is placed on the first connecting rod 3424. When the drive motor 3421 is turned on, the drive motor 3421 drives the pulley assembly 3422 to rotate, which in turn drives the bearing support 3423 to rotate, thereby driving the third suction cup assembly 341 to rotate, thereby bending the inner end panel 203 of the carton 200. The provision of the pulley assembly 3422 can adjust the rotation accuracy of the third suction cup assembly 341, thereby improving the accuracy of the bending of the inner end panel 203. Of course, a cylinder or motor can also be directly provided to drive the rotation of the third suction cup assembly 341.

[0083] In one embodiment, see Figure 5The third folding mechanism 34 further includes a manual adjustment assembly 343, which includes a rocker 3431 and two limit seats 3432. The rocker 3431 is connected to the driving mechanism 342, and the two limit seats 3432 are respectively arranged on both sides of the rocker 3431. The two limit seats 3432 are used to limit the movement range of the rocker 3431. When the driving mechanism 342 fails and cannot be used, the rocker 3431 can be shaken to drive the third suction cup assembly 341 to rotate. The rocker 3431 moves within the range defined by the two limit seats 3432, which can limit the movement range of the third suction cup assembly 341, so that the third suction cup assembly 341 can just bend the inner end panel 203 of the paper box 200, thereby preventing the third suction cup assembly 341 from moving too far and excessively squeezing the inner end panel 203 of the paper box 200, resulting in a folding failure of the paper box 200. The manual adjustment component 343 is provided so that when the driving mechanism 342 fails, the third folding mechanism 34 can still operate normally.

[0084] In one embodiment, see Figure 5 The second folding mechanism 33 is installed on the third folding mechanism 34, so that when the third folding mechanism 34 rotates, it can drive the second folding mechanism 33 to rotate. Specifically, after the second suction cup assembly 331 bends the outer end panel 204, the third suction cup assembly 341 sucks the inner end panel 203. When the driving mechanism 342 rotates, the third suction cup assembly 341 rotates to bend the inner end panel 203. At this time, the second suction cup assembly 331 and the third suction cup assembly 341 rotate synchronously, so that when the inner end panel 203 is bent, the outer end panel 204 and the inner end panel 203 always maintain the same inclination angle, so that the outer end panel 204 can be inserted between the two front panels 201.

[0085] In one embodiment, see Figure 6The unloading mechanism 40 includes a fourth suction cup assembly 41 and a moving mechanism 42 . The fourth suction cup assembly 41 is mounted on the moving mechanism 42 , and the moving mechanism 42 is mounted on the frame 10 . The fourth suction cup assembly 41 is used to suck the other front panel 201 of the carton 200, and the moving mechanism 42 is used to drive the fourth suction cup assembly 41 to move, so as to drive the corresponding front panel 201 to move, so that the fourth suction cup assembly 41 cooperates with the folding mechanism 30 to open the carton 200, so that the folding mechanism 30 folds the carton 200. At the same time, the moving mechanism 42 also transports the folded carton 200 and stacks it in the stacking mechanism 50. That is to say, when the folding mechanism 30 folds one end of the carton 200, the fourth suction cup assembly 41 sucks the other front panel 201 of the carton 200, and the moving mechanism 42 drives the front panel 201 to move until the moving mechanism 42 cooperates with the folding mechanism 30 to open the carton 200, and the folding mechanism 30 then folds one end of the carton 200. After the carton 200 is folded, the moving mechanism 42 transports the folded carton 200 to the stacking mechanism 50 and stacks it in the stacking mechanism 50.

[0086] In one embodiment, see Figure 6 The moving mechanism 42 includes a first linear drive mechanism 421 and a second linear drive mechanism 422. The first linear drive mechanism 421 is used to drive the fourth suction cup assembly 41 to and from the folding mechanism 30 and the stacking mechanism 50. The first linear drive mechanism 421 is mounted on the frame 10, and the second linear drive mechanism 422 is used to drive the fourth suction cup assembly 41 to move along the stacking direction of the paper boxes 200. The second linear drive mechanism 422 is slidably mounted on the first linear drive mechanism 421. The provision of two linear drive mechanisms that move in different directions allows for flexible movement of the fourth suction cup assembly 41 on a plane, facilitating unloading of the fourth suction cup assembly 41. At the same time, the structure is simple and easy to install and operate.

[0087] In one embodiment, the first linear drive mechanism 421 and the second linear drive mechanism 422 may be cylinders, or linear drive mechanisms such as linear moving modules.

[0088] In one embodiment, see Figure 7 and Figure 8 The feeding mechanism 20 includes a feeding assembly 21 and a conveying mechanism 22. The feeding assembly 21 is used to stack multiple paper boxes 200. The conveying mechanism 22 is set on the frame 10. The conveying mechanism 22 is used to convey the paper box 200 at the bottom layer of the feeding assembly 21 to the folding mechanism 30 so that the paper box 200 can be folded.

[0089] Further, see Figure 8The conveying mechanism 22 includes a fifth suction cup assembly 221, a sliding mechanism 222 and a driving assembly 223. The sliding mechanism 222 is installed on the frame 10. The fifth suction cup assembly 221 is used to suck the paper box 200 at the bottom of the discharge assembly 21. The driving assembly 223 is used to drive the fifth suction cup assembly 221 to drive the paper box 200 to move along the arc to the folding mechanism 30. The sliding mechanism 222 is used to position the direction of the fifth suction cup assembly 221 when the fifth suction cup assembly 221 moves in an arc. That is to say, when loading, the fifth suction cup assembly 221 sucks the paper box 200 at the bottom of the discharge assembly 21. The driving assembly 223 drives the fifth suction cup assembly 221 to move on the sliding mechanism 222 to the folding mechanism 30. The setting of the sliding mechanism 222 allows the fifth suction cup assembly 221 to move along the sliding mechanism 222 in an arc, thereby driving the carton 200 to move along the arc to the folding mechanism 30 so that the carton 200 can be folded. When the fifth suction cup assembly 221 moves, the fifth suction cup assembly 221 uses suction to extract the bottom carton 200 from the unloading assembly 21, allowing the fifth suction cup assembly 221 to drive the carton 200 to move. The sliding mechanism 222 allows the fifth suction cup assembly 221 to move along the arc, making it more convenient to transport the carton 200.

[0090] In one embodiment, see Figure 8 The sliding mechanism 222 includes two slide rails 2221 arranged opposite to each other, a slide plate 2222 slidingly connected to the two slide rails 2221, and a slider 2223 slidingly placed on the slider 2222. The fifth suction cup assembly 221 is connected to the slider 2223, and the driving assembly 223 is connected to the fifth suction cup assembly 221. The setting direction of the two slide rails 2221 is parallel to the direction from the feeding mechanism 20 to the folding mechanism 30, and the setting direction of the slider 2222 is perpendicular to the direction from the feeding mechanism 20 to the folding mechanism 30. Since the slider 2223 can slide on the slide plate 2222, the slide plate 2222 can slide on the slide rail 2221, and the slide plate 2222 is perpendicular to the setting direction of the two slide rails 2221, when the driving component 223 drives the fifth suction cup component 221 to move, the fifth suction cup component 221 moves in a direction parallel to the slide rail 2221 and parallel to the slide plate 2222 at the same time, that is, moves along an arc, so that the fifth suction cup component 221 can drive the paper box 200 to move along the arc to the folding mechanism 30.

[0091] In one embodiment, see Figure 8The driving assembly 223 includes a driving cylinder 2231 and a second connecting rod 2232. The second connecting rod 2232 is connected to the fifth suction cup assembly 221. The driving cylinder 2231 drives the second connecting rod 2232 to swing, thereby driving the fifth suction cup assembly 221 to swing on the sliding mechanism 222, so that the fifth suction cup assembly 221 can drive the paper box 200 to move along the arc direction. It is understandable that the driving assembly 223 can also be configured as a driving cylinder or a driving motor.

[0092] In one embodiment, see Figure 7 The unloading assembly 21 includes a plurality of first limiting rods 211 and two first supporting plates 212 arranged opposite to each other. The plurality of first limiting rods 211 are arranged on the frame 10. The two first supporting plates 212 are respectively placed at one end of the plurality of first limiting rods 211. The plurality of first limiting rods 211 are used to limit the position of the paper box 200. The two first supporting plates 212 are used to support the opposite sides of the paper box 200 to facilitate the conveying mechanism 22 to extract the bottom paper box 200 and convey it to the folding mechanism 30.

[0093] In one embodiment, see Figure 7 The stacking mechanism 50 includes multiple second limiting rods 51, two second supporting plates 52 and two supporting driving members 53. The multiple second limiting rods 51 are arranged on the frame 10, and the two second supporting plates 52 are respectively placed at one end of the multiple second limiting rods 51. The two supporting driving members 53 are installed on the frame 10. The two supporting driving members 53 correspond one-to-one to the two second supporting plates 52. The multiple second limiting rods 51 are used to limit the position of the paper box 200, and the two second supporting plates 52 are used to support the opposite sides of the paper box 200. The two supporting driving members 53 are used to drive the corresponding second supporting plates 52 to abut or release the bottom paper box 200. After the carton 200 is folded, the unloading mechanism 40 conveys the folded carton 200 to the bottom of the stacking mechanism 50. At this time, the two supporting driving members 53 respectively drive the corresponding second supporting plates 52 to release the carton 200. The unloading mechanism 40 further drives the folded carton 200 to push upward until the carton 200 is located above the two second supporting plates 52. Then, the two supporting driving members 53 respectively drive the corresponding second supporting plates 52 to resist the carton 200 at the bottom layer, thereby stacking the folded carton 200. It can be understood that the supporting driving member 53 can be a linear drive such as a cylinder or a linear module.

[0094] It can be understood that the first suction cup assembly 31, the second suction cup assembly 41, the third suction cup assembly 331, the fourth suction cup assembly 341 and the fifth suction cup assembly 221 include a support member and multiple suction cups. The support member is used to support multiple suction cups. The support member can be a support plate, a support block, a support seat or other components that can be used to support the suction cups.

[0095] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
