The side folding assembly 2 folds and seals the side portion 111 of the box body 1; folding means sealing after folding, that is, first folding the side portion 111, and then sealing the side portion 111 in the box bottom 12; similarly, the ear folding assembly 3 is used to fold and seal the ear portion 112 of the box body 1. By setting a control module, a driving module, a conveying assembly for conveying the box body 1, and a folding side assembly 2 and an ear folding assembly 3 arranged in sequence along the conveying direction of the conveying assembly, the sealing action of the box body 1 is automatically completed, which improves the packaging efficiency and ensures the packaging quality compared to manual packaging.

[0040] Furthermore, if Figure 4 As shown, in this embodiment, the above-mentioned side folding assembly 2 includes a supporting mechanism 21, a fixing mechanism 22 and a folding mechanism 23, and the supporting mechanism 21, the fixing mechanism 22 and the folding mechanism 23 are all connected to the above-mentioned driving module to be driven by the driving module.

[0041] Further, in the present embodiment, the supporting mechanism 21 comprises a first rotating shaft 211 and a rear block rod 212, wherein the first rotating shaft 211 is fixed on the workpiece 51 of the machine table 5, the first rotating shaft 211 is perpendicular to the conveying direction of the conveying assembly, and the rear block rod 212 is fixed on the first rotating shaft 211; specifically, the number of the rear block rods 212 is 2, which are mirror-distributed on the first rotating shaft 211, and the first rotating shaft 211 is connected to the driving module; specifically, the first rotating shaft 211 is connected to the first rotating cylinder 41, and the first rotating cylinder 41 is connected to an external air source, and the control module controls the first rotating cylinder 41 to control the first rotating shaft 211 to rotate around its own axis, and when the first rotating shaft 211 rotates, it drives the rear block rod 212 to rotate, and the rear block rod 212 is attached to the outer surface of the top cover 11 of the box body 1, and presses down the top cover 11 in the flipped-up state when rotating.

When the second rotating shaft 221 rotates, the front pressure rod 222 is driven to rotate, and the front pressure rod 222 is attached to the inner surface of the top cover 11 of the box body 1, and cooperates with the above-mentioned rear stop rod 212 to fix the top cover 11 of the box body 1 so that it cannot flip over.

[0043] Further, in this embodiment, the folding mechanism 23 includes a side pressure plate 232 and a third rotating shaft 231, wherein the third rotating shaft 231 is vertically arranged and connected to the driving module to drive it to rotate around its own axis; specifically, the third rotating shaft 231 is connected to the slide cylinder 43 through a connecting rod mechanism, and the slide cylinder 43 is connected to an external air source. When the slide cylinder 43 moves forward and backward, the third rotating shaft 231 is driven to rotate through the connecting rod mechanism, and the side pressure plate 232 is fixed on the third rotating shaft 231. When the third rotating shaft 231 rotates, it drives the side pressure plate 232 to squeeze the side edge 111 of the top cover 11, so that it folds inward. After the folding action is completed, the rear stopper 212 of the support mechanism 21 rotates to press the top cover 11 downward, so that the side edge 111 is sealed in the box bottom 12.

[0044] Furthermore, if Figure 2As shown, in the present embodiment, the above-mentioned folding ear assembly 3 includes: a first frame 31, which is C-shaped, with both ends extending downward, and the first frame 31 is rigidly connected to the electric cylinder slider. When the electric cylinder is working, the electric cylinder slider drives the first frame 31 to move up and down. During the movement, its two ends press down the ear 112 of the box body 1 to fold it; the second frame 32 is rigidly connected to the electric cylinder slider. When the electric cylinder slider moves, it drives the first frame 31 and the second frame 32 to move at the same time. The second frame 32 is located on the upper part of the first frame 31 and is connected to the first frame 31 through an elastic component 34, specifically, a spring connection; the limit block 33 is located below the two ends of the first frame 31. When the first frame 31 moves downward, it stops moving when it moves to the position of contacting the limit block 33, but due to the second frame 32 The first frame 31 and the second frame 32 are connected by an elastic component 34, and the second frame 32 will still keep moving at this time; the pressure block 35 is fixed in the middle position of the first frame 31 and extends downward. When the first frame 31 moves downward, the pressure block 35 squeezes the ear 112 of the box body 1 to fold it; the scraper 36, the scraper 36 is rigidly connected to the fourth shaft 37, and the two ends of the fourth shaft 37 are arranged at the two ends of the first frame 31 and are rotatably connected to the two ends of the above-mentioned second frame 32. Specifically, the fourth shaft 37 is connected to the two ends of the second frame 32 through a connecting rod mechanism. When the electric cylinder is working, when the first frame 31 is blocked by the limit block 33 and the second frame 32 moves downward alone, the fourth shaft 37 is driven to rotate, and at the same time the scraper 36 is flipped to fold the ear 112 of the box body 1.

[0045] Furthermore, if Figure 1 As shown, in the present embodiment, the folding ear assembly 3 further includes a guiding component 38, which is connected to the driving module and is arranged directly below the pressing block 35. The driving module drives the guiding component 38 to perform reciprocating linear motion toward the box body 1. The guiding component 38 further includes an arc surface. After the pressing block folds the ear 112 of the box body 1, the guiding component 38 moves toward the box body 1, and the ear 112 is inserted into the box bottom 12 under the guidance of the arc surface.

[0046] Furthermore, if Figure 1As shown, in this embodiment, the above-mentioned conveying assembly includes a belt conveying section, a push rod conveying section and a drag chain conveying section in sequence along the conveying direction. The belt conveying section includes two parallel belts 611, and the belts 611 are driven by a driving module. The box body 1 is placed on the belts 611 and is conveyed forward by the friction between the belts 611 and the belts 611. At the same time, a photoelectric switch is provided on the outer side of the belts 611, and a blocking mechanism is provided between the tracks formed by the two belts 611, and the blocking mechanism can block the box body 1 from moving forward; the push rod conveying section includes a push rod 621 connected to the driving module. When the push rod 621 moves forward, it pushes the box body 1 to move forward. When the push rod 621 moves backward to the limit position, it hits the roller of the blocking mechanism. The rotation of the roller drives the upper baffle to rotate so that it is lower than the surface of the belt 611 track, so that it cannot block the movement of the box body 1. The push rod 621 is arranged between the two belts 611. When the box body 1 is driven by the belts When the belt 611 is conveying, the push rod 621 is lower than the surface of the belt 611 track. When the box body 1 enters the conveying section of the push rod 621, the belt 611 stops rotating, and the push rod 621 first moves upward to make it higher than the surface of the belt 611 track, and then moves forward to push the box body 1. After the box body 1 is conveyed into the drag chain conveying section, the push rod 621 retreats backward, and when it retreats to the extreme position, it hits the roller of the blocking mechanism. At this time, if the photoelectric switch detects that there is a box body 1 on the belt 611, it sends a signal to the control module, and the control module controls the driving module to drive the belt 611 to rotate to convey the next box body 1; the drag chain conveying section includes a drag chain 632 connected to the driving module, a slide 631 and a carrier 633 for carrying the box body 1. The box body 1 enters the carrier 633 after being conveyed by the push rod 621, and then the drag chain 632 drags the carrier 633 on its top to slide on the slide 631 to convey the box body 1.

[0047] The working process of the entire automatic box sealing machine is as follows: the belt 611 transports the box body 1 to the side folding assembly 2, the rear stopper 212 in the support mechanism 21 rotates clockwise and presses against the outer surface of the top cover 11 of the box body 1, then the front pressure rod 222 of the fixing mechanism 22 rotates counterclockwise and presses against the inner surface of the top cover 11 of the box body 1, and then the side pressure plate 232 folds the side edge 111 of the top cover 11 of the box body 1, after the folding is completed, the rear stopper 212 rotates counterclockwise to press down the top cover 11 of the box body 1, at this time the side edge 111 is sealed in the box bottom 12, then the push rod 621 pushes the box body 1 to the carrier 633, the drag chain 632 transports the carrier 633 to the ear folding assembly 3 station, the electric cylinder works to make the slider drag the first frame 31 and the second frame 32 downward, at this time the two ends of the first frame 31 and the pressing block 35 press the box down together The ear 112 of the top cover 11 of the box body 1 is folded, and when the first frame 31 moves to the position of contacting the limit block 33, it stops moving, and the second frame 32 continues to move downward. At this time, the second frame 32 drives the fourth shaft 37 to rotate, so that the scraper 36 rigidly connected to the fourth shaft 37 scrapes the ear 112 of the box body 1, so that it is sealed into the box bottom 12; when the guide component 38 is added, between the synchronous movement of the first frame 31 and the second frame 32 and the independent movement of the second frame 32, there is also an action that the guide component 38 moves toward the box body 1 so that the end of the arc surface is inserted into the box bottom 12. When the scraper 36 scrapes the ear 112 of the box body 1, the position of the ear 112 folded by the pressing block is guided by the arc surface of the guide component 38 and smoothly inserted into the box bottom 12, completing the folding and sealing of the box body 1.

[0053] like Figure 1-Figure 4 As shown, in a specific implementation manner, the box sealing method of the automatic box sealing machine includes the steps of:

[0054] S11, using the photoelectric switch arranged on the outer side of the belt 611 to detect whether the box body 1 is present at the initial position, and at the same time, to detect whether the push rod 631 is in the original position; if so, proceed to the next step;

[0055] S12, the driving module drives the belt 611 to rotate, and the belt 611 conveys the box body 1 forward; the push rod 631 first moves upward to make itself higher than the surface of the belt 611 track, and then pushes the box body 1 forward; at the same time, the first rotating shaft 211 rotates clockwise to make the rear blocking rod 212 close to the outer surface of the top cover 11 of the box body 1;

[0056] S13, the second rotating shaft 221 rotates counterclockwise, driving the front pressing rod 222 to rotate, and the front pressing rod 222 is closely attached to the inner surface of the top cover 11 of the box body 1, and cooperates with the rear blocking rod 212 to clamp and fix the top cover 11;

[0057] S14, the third rotating shaft 231 rotates to drive the side pressure plate 232 to fold the side edge; the first rotating shaft 211 rotates counterclockwise to make the rear stopper 212 press down the top cover 11 to seal the side edge 111;

[0058] S15, the push rod 631 pushes the box body 1 forward again, and transports the box body 1 to the carrier 633, and the movement of the drag chain 632 drives the carrier 633 to transport the box body 1 forward, so that the box body 1 reaches the position of the folding ear component 3;

[0059] S16, the electric cylinder works, so that the slider drives the first frame 31 and the second frame 32 to move downward synchronously. At this time, both ends of the first frame 31 and the pressing block 35 press down the folding ear 112 together;

[0060] S17, the guide component 38 of the folding ear assembly 3 moves toward the box body 1, so that the arc-surface guide ear portion 112 of the guide component 38 is inserted into the box bottom 12;

[0061] S18, the electric cylinder works again. At this time, the first frame 31 stops moving due to the action of the limit block, and the second frame 32 continues to move downward, driving the fourth rotating shaft 37 to rotate, so that the scraper 36 scrapes the ear 112 to seal it into the box bottom 12, completing the folding and sealing of the box body 1.
