[0033] like Figure 1 and Figure 2 As shown, some embodiments of the present application provide a carton sealing device, including a frame assembly 1, a conveying mechanism 2, a folding mechanism 3 and a gluing mechanism 4, wherein the conveying mechanism 2, the folding mechanism 3 and the gluing mechanism 4 are all installed on the frame assembly 1, and the folding mechanism 3 is located below the conveying mechanism 2, and the gluing mechanism 4 is located above the conveying mechanism 2.

[0034] The conveying mechanism 2 is used to move the material box along the conveying direction and is equipped with a flap folding station and a box sealing station. When the material box moves to the flap folding station, the lifting assembly of the flap folding mechanism 3 drives the flap folding robot to extend from under the conveying mechanism 2 to fold the swing flap of the material box. After the swing flap is folded, the material box is further conveyed by the conveying mechanism 2 until it is conveyed to the box sealing station. When the material box moves to the box sealing station, the roller assembly of the gluing mechanism 4 rolls the tape onto the material box to complete the box sealing operation. The above operation does not require human intervention throughout, which not only improves automation but also helps improve the efficiency of box sealing to meet the production efficiency of the production line.

[0035] Exemplarily, the material box is used to package products and can be set as a cardboard box.

[0036] In some embodiments, the conveying mechanism 2 includes a first pushing assembly 21, a first roller conveyor line 22, and a second roller conveyor line 23. The first roller conveyor line 22 and the second roller conveyor line 23 are connected horizontally and vertically, that is, the conveying directions of the first roller conveyor line 22 and the second roller conveyor line 23 are arranged horizontally and vertically. The cover folding station is located at the conveying end of the first roller conveyor line 22, that is, the material box is transported to the cover folding station via the first roller conveyor line 22; the box sealing station is located at the front end of the second roller conveyor line 23, and the material box is moved from the cover folding station to the box sealing station via the first pushing assembly 21.

[0037] Exemplarily, the first pushing assembly 21 includes a fifth driving member 211, a belt line connected to the fifth driving member 211, a first linear guide 212, a first push plate 213 connected to both the belt line and the first linear guide 212, position switches located at both ends of the first linear guide 212, and an insert mounted on the first push plate 213 that cooperates with the position switch. The fifth driving member 211 drives the belt line to move, thereby driving the first push plate 213 to move along the guide direction of the first linear guide 212, thereby pushing the material box from the cover folding station to the box sealing station. When the insert inserts into the position switch located at the beginning of the first linear guide 212, it indicates that the first push plate 213 is in the initial position; when the insert inserts into the position switch located at the end of the first linear guide 212, it indicates that the first push plate 213 is in the final position.

[0038] Exemplarily, the fifth driving member 211 provides driving force for the movement of the belt line, including but not limited to being set as a servo motor, etc.

[0039] like Figure 3 As shown, in some embodiments, the frame assembly 1 is further mounted with a second pushing assembly 5 and a third pushing assembly 6, both of which are located below the conveying mechanism 2. Furthermore, the frame assembly 1 is provided with a first limiting surface 11 corresponding to the second pushing assembly 5 and a second limiting surface 12 corresponding to the third pushing assembly 6. After the first roller conveyor line 22 conveys the material box to the cover folding station, the second pushing assembly 5 and the third pushing assembly 6 extend from below the conveying mechanism 2 and push the material box until it abuts against the first limiting surface 11 and the second limiting surface 12, thereby positioning the material box at the cover folding station and preparing for the subsequent folding of the swing cover of the material box.

[0040] Exemplarily, more than one set of the second pushing assembly 5 and the third pushing assembly 6 can be provided, and the actual number provided is set according to actual needs. The second pushing assembly 5 includes a sixth driving member 51, a seventh driving member 52 connected to the sixth driving member 51, and a second push plate 53 connected to the seventh driving member 52. The sixth driving member 51 drives the second push plate 53 to extend or retract into the conveying mechanism 2, and the seventh driving member 52 drives the second push plate 53 to push the material box against the first limit surface 11. The third pushing assembly 6 includes an eighth driving member 61, a ninth driving member 62 connected to the eighth driving member 61, and a third push plate 63 connected to the ninth driving member 62. The eighth driving member 61 drives the third push plate 63 to extend or retract into the conveying mechanism 2, and the ninth driving member 62 drives the third push plate 63 to push the material box against the second limit surface 12.

[0041] Exemplarily, the sixth driving member 51 , the seventh driving member 52 , the eighth driving member 61 and the ninth driving member 62 provide driving force for the movement of the second push plate 53 and the third push plate 63 , including but not limited to being set as linear cylinders, etc.

[0042] It should be noted that the first limiting surface 11 is arranged along the conveying direction of the second roller conveyor line 23, and a plurality of rolling elements are arranged on the surface of the first limiting surface 11 in contact with the material box, and a plurality of rolling elements are also arranged on the second push plate 53 arranged opposite to the first limiting surface 11, which is beneficial to reducing the friction generated during the movement of the material box, thereby helping to reduce the thrust required by the first push plate 213 to push the material box to move, and helping to reduce costs.

[0043] In some embodiments, the cover folding robot includes a first cover folding robot 31 and a second cover folding robot 32 located circumferentially of the cover folding station. There are two first cover folding robots 31 and they are arranged opposite to each other. There are also two second cover folding robots 32 and they are arranged opposite to each other.

[0044] After the material box is positioned at the flap folding station, flap folding robots are installed on all four sides of the material box to fold the four flaps. The first flap folding robot 31 folds the first two flaps of the material box, which are located opposite each other. The second flap folding robot 32 folds the second two flaps of the material box, which are located opposite each other. This completes the folding of all four flaps.

[0045] For example, the first flap folding robot 31 is used to fold the two flaps on the short side of the material box, and the second flap folding robot 32 is used to fold the two flaps on the long side of the material box. During the folding process, the first flap folding robot 31 folds the two flaps on the short side first, and then the second flap folding robot 32 folds the two flaps on the long side.

[0046] Specifically, the first cover folding robot 31 includes a first driving member 311 and a first pressing head 312 connected to the first driving member 311. When the first driving member 311 drives the first pressing head 312 to flip, the first pressing head 312 folds the swing cover of the material box. The second cover folding robot 32 includes a second driving member 321 and a second pressing head 322 connected to the second driving member 321. When the second driving member 321 drives the second pressing head 322 to flip, the second pressing head 322 folds the swing cover of the material box.

[0047] Exemplarily, the first driving member 311 provides driving force for the flipping of the first pressing head 312 , including but not limited to being set as a flip cylinder, etc. The second driving member 321 provides driving force for the flipping of the second pressing head 322 , including but not limited to being set as a flip cylinder, etc.

[0048] In some embodiments, the lifting assembly includes a fourth movable assembly 33 and a fifth movable assembly 34. The first flap folding robot 31 is connected to the movable end of the fourth movable assembly 33, so that the fourth movable assembly 33 drives the first flap folding robot 31 to extend or retract to the conveying mechanism 2. The second flap folding robot 32 is connected to the movable end of the fifth movable assembly 34, so that the fifth movable assembly 34 drives the second flap folding robot 32 to extend or retract to the conveying mechanism 2.

[0049] Specifically, the fourth moving assembly 33 includes a first bracket 331 connected to the frame assembly 1, a tenth driving member 332 connected to the first bracket 331, and a first adapter 333 connected to the tenth driving member 332. The first flap folding robot 31 is connected to the first adapter 333. The tenth driving member 332 is used to drive the first flap folding robot 31 to extend or retract to the conveying mechanism 2. The fifth moving assembly 34 includes a second bracket 341 connected to the frame assembly 1, an eleventh driving member 342 connected to the second bracket 341, a second adapter 343 connected to the eleventh driving member 342, and a twelfth driving member 344 connected to the second adapter 343. The second flap folding robot 32 is connected to the driving end of the twelfth driving member 344. Both the eleventh driving member 342 and the twelfth driving member 344 are used to drive the second flap folding robot 32 to extend or retract to the conveying mechanism 2.

[0050] Exemplarily, the tenth driving member 332 , the eleventh driving member 342 and the twelfth driving member 344 provide driving force for the cover folding robot to extend or retract the conveying mechanism 2 , including but not limited to being set as linear cylinders, etc.

[0051] It should be noted that the screw holes for connecting the first bracket 331 and the second bracket 341 to the frame assembly 1 are configured as strip holes to adjust the position of the cover folding robot, thereby increasing the versatility of the carton sealing device of the present application.

[0052] like Figure 4 As shown, in some embodiments, the frame assembly 1 is further equipped with a flattening mechanism 7, located above the conveyor mechanism 2, to press against the folded flap of the material box, preparing for subsequent tape sealing. The flattening mechanism 7 includes a first moving assembly 71 and a pressure plate 72. After the flap of the material box is folded, the first moving assembly 71 drives the pressure plate 72 toward the material box, pressing it against the flap to maintain its folded state. Subsequently, the first pushing assembly 21 pushes the material box away from the flap folding station and toward the sealing station.

[0053] It should be noted that two flattening mechanisms 7 are provided, one on each side of the gluing mechanism 4, so that they can flatten the two opposing flaps of the second material box. The flattening mechanism 7 also includes a second movable assembly 73 connected to the first movable assembly 71, and a third movable assembly 74 connected to the second movable assembly 73. A pressure plate 72 is connected to the third movable assembly 74. The second movable assembly 73 drives the pressure plate 72 toward or away from the gluing mechanism 4, allowing the spacing between the two pressure plates 72 to decrease or increase to accommodate material boxes of varying sizes, thereby enhancing the versatility of the box sealing device. The third movable assembly 74 drives the pressure plate 72 along the conveying direction of the conveyor mechanism 2, i.e., along the conveying direction of the second roller conveyor line 23. After the flap folding robot folds the flap of the material box, the third movable assembly 74 drives the pressure plate 72 toward the first roller conveyor line 22, i.e., toward the flap folding station, so that the pressure plate 72 is directly above the material box. The first movable assembly 71 then drives the pressure plate 72 to press against the flap. When the material box moves to the box sealing station, the third moving assembly 74 drives the pressing plate 72 to move toward the box sealing station, so that the pressing plate 72 remains pressed on the swing cover of the material box.

[0054] Specifically, the first moving assembly 71 includes a thirteenth driving member and a plurality of guide rods located circumferentially therefrom. The thirteenth driving member drives the second moving assembly 73 toward or away from the material bin along the guide directions of the guide rods. The second moving assembly 73 includes a fourteenth driving member and a second linear guide. The fourteenth driving member drives the third moving assembly 74 toward or away from the gluing mechanism 4 along the guide directions of the second linear guide. The third moving assembly 74 includes a fifteenth driving member and a third linear guide. The fifteenth driving member drives the pressure plate 72 to move back and forth along the guide directions of the third linear guide in the conveying direction of the second roller conveyor line 23.

[0055] Exemplarily, the thirteenth driving member provides driving force for the movement of the second moving assembly 73, the fourteenth driving member provides driving force for the movement of the third moving assembly 74, and the fifteenth driving member provides driving force for the movement of the pressure plate 72. The thirteenth driving member, the fourteenth driving member and the fifteenth driving member include but are not limited to being set as linear cylinders, etc.

[0056] like Figure 5 As shown, in some embodiments, the roller assembly includes a third drive member 41, a first roller 42, a fourth drive member 43, and a second roller 44. The first roller 42 is connected to the drive end of the third drive member 41, and the second roller 44 is connected to the drive end of the fourth drive member 43. The third drive member 41 drives the first roller 42 to extend or retract. When the first roller 42 extends, the adhesive tape is rolled onto the material box. The fourth drive member 43 drives the second roller 44 to extend or retract. When the second roller 44 extends, the adhesive tape is rolled onto the material box. The first roller 42 and the second roller 44 are arranged sequentially along the conveying direction of the conveying mechanism 2. That is, the first roller 42 is used to roll the adhesive tape onto the front end of the material box, and the second roller 44 is used to roll the adhesive tape onto the rear end of the material box.

[0057] Exemplarily, the third driving member 41 provides driving force for the movement of the first roller 42, and the fourth driving member 43 provides driving force for the movement of the second roller 44. The third driving member 41 and the fourth driving member 43 include but are not limited to being set as linear cylinders, etc.

[0058] In some embodiments, the gluing mechanism 4 further includes a roller assembly 45 and a cutter 48 assembly. The roller assembly 45 is used to wind the tape, and the protruding end of the tape is close to the first roller 42; the cutter 48 assembly is used to cut the tape and is located between the first roller 42 and the second roller 44.

[0059] When the first pusher assembly 21 pushes the front end of the material box to the initial end of the sealing station, the third drive member 41 drives the first roller 42 to extend, rolling the extended end of the tape onto the material box. Subsequently, the third drive member 41 drives the first roller 42 back to its original position. The first pusher assembly 21 then continues to push the material box through the sealing station. The moving material box now drives the tape wrapped around the roller assembly 45 to follow the movement of the material box. The returned first roller 42 and second roller 44 can then adhere the tape to the material box.

[0060] When the first pushing assembly 21 pushes the rear end of the material box to the end of the sealing station, the cutter 48 assembly cuts the tape, and the fourth driving member 43 drives the second roller 44 to extend, rolling the end of the cut tape onto the material box to complete the sealing of the material box.

[0061] It should be noted that in order to further improve the versatility of the carton sealing device of the present application, an elastic structure 46 is provided between the third driving member 41 and the first roller 42, and between the fourth driving member 43 and the second roller 44, so that the carton sealing device of the present application can adapt to material boxes of different height specifications, which is conducive to improving the versatility of the carton sealing device of the present application.

[0062] Exemplarily, the elastic structure 46 may include a first mounting plate, a second mounting plate, a guide pin, an elastic member, and an anti-slip member. The first mounting plate and the second mounting plate are spaced apart, and two or more guide pins are disposed between the first mounting plate and the second mounting plate. One end of the guide pin is fixedly mounted on the first mounting plate, and the other end of the guide pin is slidably mounted on the second mounting plate. The movable end of the guide pin is connected to the anti-slip member to prevent the guide pin from falling off the second mounting plate. Each guide pin is sleeved with an elastic member, which is located between the first mounting plate and the second mounting plate.

[0063] Exemplarily, the cutter 48 assembly includes a sixteenth drive member 47 and a cutter 48. The cutter 48 is mounted on the driving end of the sixteenth drive member 47 so that the sixteenth drive member 47 can drive the extension and retraction of the cutter 48. The sixteenth drive member 47 includes, but is not limited to, a linear cylinder.

[0064] It should be noted that when the push plate of the first push assembly 21 pushes the rear end of the material box to the end of the sealing station, the push plate moves to its final position. Then, the fifth drive member 211 drives the push plate back to its initial position, preparing for the next push of the material box from the flap folding station to the sealing station. During this process, the second roller conveyor line 23 transports the sealed material box to the next station.

[0065] To sum up, the utility model provides a box sealing device, which installs a conveying mechanism on the frame assembly, so that the material box can be moved from the folding station to the box sealing station, and the folding station is provided with a folding robot, which folds the swing cover of the material box by the folding robot, and the box sealing station is provided with a gluing station, which rolls the tape onto the material box after the swing cover is folded by the roller assembly to complete the sealing operation of the material box. No human participation is required throughout the process, which improves automation while also helping to improve the efficiency of box sealing and meet the production efficiency of the production line.

[0066] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
