In the prior art, a folding and labeling device and method for automatic packaging of electronic products are disclosed, and the patent number is CN111661435A. The device can be classified as a horizontal cartoning machine. In terms of structure, a plurality of clamping structures are arranged along the circumferential direction on the surface of the turntable, and the loading assembly and the box sealing assembly are distributed around the turntable. When the device is boxing, it is necessary to manually seal the opening on one side of the carton in advance, and the opening on the other side of the carton is used to allow the product to enter the carton. Then, the carton is placed flat in the clamping structure. At this time, the opening of the carton is close to the outer periphery of the turntable, and the loading assembly is used to push the product into the opening of the carton, and then the box sealing assembly is used to seal the opening of the carton.

[0004] However, the existing box sealing assembly can only seal one opening of the paper box at the outer periphery of the turntable. Since the other opening of the paper box is close to the rotating axis of the turntable, the opening can only be sealed manually in advance, which requires additional box sealing operators, and the degree of automation of the box loading equipment is low, which reduces the efficiency of the box loading operation. Summary of the invention

The ear folding mechanism, the cover folding mechanism, the tongue folding mechanism and the covering mechanism are arranged between the positioning component and the rotating shaft of the turntable. Such an arrangement makes the box sealing device close to the opening of the paper box toward the rotating shaft of the turntable. Therefore, during the paper box sealing process, the ear folding mechanism folds the two ears of the paper box toward the opening of the paper box, then the cover folding mechanism folds the cover plate of the paper box toward the opening of the paper box, then the tongue folding mechanism folds the tongue of the cover plate toward the opening of the paper box, and finally, the covering mechanism inserts the tongue of the cover plate into the opening of the paper box, so as to achieve the sealing of the opening of the paper box toward the rotating shaft of the turntable, without the need for manual box sealing operations, thereby improving the degree of automation of the box loading equipment, improving the box loading efficiency, and reducing labor costs. In addition, the ear folding mechanism, the cover folding mechanism, the tongue folding mechanism and the covering mechanism make full use of the space between the positioning component and the rotating shaft of the turntable to reduce the floor space of the box sealing device.

[0009] According to a box sealing device of a cartoning machine according to an embodiment of the present application, the ear folding mechanism includes two ear folding components, the rotating shaft of the turntable is accommodated between the two ear folding components, and the two ear folding components can move relatively close to each other so that the two ears are folded toward the opening of the paper box.

[0013] The benefit is that: the present application sets up a movable frame and a first power member, and uses the first power member to drive the movable frame close to the opening of the paper box, and the movable frame moves the folding ear assembly to the ear folding position, so as to facilitate the precise folding of the ear folding assembly, and uses the first power member to drive the movable frame away from the opening of the paper box, so that the folding ear assembly is away from the positioning assembly, thereby avoiding interference between the positioning assembly and the folding ear assembly during the process of the positioning assembly following the rotation of the turntable.

[0014] In addition, the movable rack is located on the side of the rotating axis of the turntable away from the positioning component, and there is more space on the side of the rotating axis of the turntable away from the positioning component. This makes it easier to arrange the movable rack, and a larger movable rack can be designed, which is beneficial to improving the stability of the movable rack.

[0016] The benefit is that: the present application sets a cantilever, a first push block and a second power member, and uses the second power member to drive the cantilever to move, so that the first push block follows the movement of the cantilever, so that the first push block folds the ear of the paper box toward the opening of the paper box, and the second power member does not need to be directly connected to the first push block, so that the second power member can be away from the positioning assembly, reducing the space occupied around the positioning assembly, and facilitating the arrangement of the folding cover mechanism, the folding tongue mechanism and the covering mechanism around the positioning assembly.

[0017] According to an embodiment of the present application, a box sealing device of a box packing machine further includes a bracket, which is located between the two folding ear assemblies, and the folding cover mechanism, the folding tongue mechanism and the covering mechanism are installed on the bracket.

[0020] Advantageously, the present application provides a folding block and a third power member, and utilizes the third power member to drive the folding block to move. The folding block can push the cover plate so that the cover plate is folded toward the opening of the paper box, making it easier for the folding tongue mechanism to accurately fold the tongue piece toward the opening of the paper box.

[0021] According to an embodiment of the present application, a box sealing device of a cartoning machine further includes a box sucking mechanism, which is located at the box sealing station on the side of the positioning component away from the supporting surface.

[0023] In addition, the present application sets up a suction component and a fourth power member, and uses the fourth power member to drive the suction component to move. The suction component sucks the opposite side wall of the paper box side wall connected to the cover plate to prevent the paper box side wall from sinking inward, making it easier for the subsequent tongue piece to be accurately inserted into the opening of the paper box.

[0024] According to a box sealing device of a box packing machine according to an embodiment of the present application, the folding tongue mechanism includes a folding tongue member and a fifth power member that drives the folding tongue member to move, the folding tongue member includes a first abutment plate and a second abutment plate that are connected to each other, the first abutment plate is used to abut against the tongue piece, and the second abutment plate is used to abut against the cover plate.

[0025] What is beneficial is that: the present application sets up a folding tongue member and a fifth power member, and uses the fifth power member to drive the folding tongue member to move. The folding tongue member uses the first abutment plate to abut against the tongue piece, so that the tongue piece is folded toward the opening of the paper box, and the second abutment plate abuts against the cover plate to push the cover plate to a vertical state, which is convenient for the closing mechanism to push the cover plate so that the tongue piece can be accurately inserted into the opening of the paper box.

[0029] The benefit is that: the present application sets a guide, and the positioning assembly rotates with the turntable. Before the paper box sealing operation of the positioning assembly, it will pass through the guide. The guide uses the first guide plate and the second guide plate to limit the position of the cover of the paper box, thereby preventing the cover of the paper box from tilting higher than the standard working position, causing the folding mechanism to be unable to fold the cover, and also preventing the cover of the paper box from drooping below the standard working position, causing interference between the ears of the paper box and the cover when the ear folding mechanism is folding the ears.

[0043] A carton sealing device of a cartoning machine according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0044] Reference Figure 1 , the present application aims to provide an embodiment of a carton sealing device of a cartoning machine.

[0045] In the construction of the carton, refer to Figure 6 The paper box includes a box body 370, ears 380 and a cover plate 390. Both ends of the box body 370 have openings, each opening is provided with a cover plate 390 and two ears 380, the two ears 380 are respectively connected to the two opposite side walls of the opening of the box body 370, the cover plate 390 is connected to one side wall of the box body 370 and is located between the two ears 380, and the edge of the cover plate 390 away from the box body 370 has a tongue 400.

[0046] It should be noted that the openings at both ends of the box body 370 are arranged in the length direction of the box body 370 , on the plane where the openings are located, the two ears 380 are arranged in the width direction of the box body 370 , and the cover plate 390 is arranged in the thickness direction of the box body 370 .

[0047] Generally, cartoning machines include horizontal disc cartoning machines and vertical disc cartoning machines. The horizontal disc cartoning machine can operate on horizontally placed cartons with the length direction of the cartons in the horizontal direction, while the vertical disc cartoning machine can operate on vertically placed cartons with the length direction of the cartons in the vertical direction. In this embodiment, the horizontal disc cartoning machine is taken as an example.

[0048] A box sealing device of a box packing machine according to an embodiment of the present application, referring to Figure 5 The cartoning machine includes a turntable 100 having a support surface and a positioning assembly 110 disposed on the support surface. The positioning assembly 110 is used to limit the position of the paper box.

[0049] Further, refer to Figure 1 and Figure 5 The box sealing device includes an ear folding mechanism 120, a cover folding mechanism 130, a tongue folding mechanism 140 and a covering mechanism 150, which are located on the side of the rotation axis of the positioning component 110 close to the turntable 100. The ear folding mechanism 120 is used to fold the two ears 380 of the paper box toward the opening of the paper box, the cover folding mechanism 130 is used to fold the cover plate 390 of the paper box toward the opening of the paper box, the tongue folding mechanism 140 is used to fold the tongue piece 400 of the cover plate 390 toward the opening of the paper box, and the covering mechanism 150 is used to insert the tongue piece 400 of the cover plate 390 into the opening of the paper box.

[0050] It can be understood that, in this embodiment, the ear folding mechanism 120, the cover folding mechanism 130, the tongue folding mechanism 140 and the capping mechanism 150 are arranged between the positioning assembly 110 and the rotating shaft of the turntable 100. Such an arrangement makes the box sealing device close to the opening of the carton toward the rotating shaft of the turntable 100. Therefore, during the carton capping process, the ear folding mechanism 120 folds the two ears 380 of the carton toward the opening of the carton, and then the cover folding mechanism 130 folds the cover plate 390 of the carton toward the opening of the carton. Mouth, then, the tongue folding mechanism 140 folds the tongue piece 400 of the cover plate 390 toward the opening of the paper box, and finally, the closing mechanism 150 inserts the tongue piece 400 of the cover plate 390 into the opening of the paper box, so as to seal the opening of the paper box toward the rotating axis of the turntable 100, without the need for manual box sealing operations, thereby improving the degree of automation of the box loading equipment, improving the box loading efficiency, and reducing labor costs. In addition, the ear folding mechanism 120, the cover folding mechanism 130, the tongue folding mechanism 140 and the closing mechanism 150 make full use of the space between the positioning assembly 110 and the rotating axis of the turntable 100 to reduce the footprint of the box sealing device.

[0051] In some embodiments of the present application, reference Figure 3 , and also includes a guide 340, the guide 340 has a first guide plate 350 and a second guide plate 360 ​​that are arranged opposite to each other. Before the positioning assembly 110 moves to the box sealing station, the cover plate 390 is accommodated between the first guide plate 350 and the second guide plate 360 ​​to pass through.

[0052] It can be understood that in this embodiment, by setting the guide 340, the positioning assembly 110 rotates with the turntable 100. Before the paper box sealing operation of the positioning assembly 110, it will pass through the guide 340. The guide 340 uses the first guide plate 350 and the second guide plate 360 ​​to limit the position of the cover 390 of the paper box, thereby preventing the cover 390 of the paper box from tilting up higher than the standard working position, causing the folding mechanism 130 to be unable to perform the cover folding operation, and also preventing the cover 390 of the paper box from drooping below the standard working position, causing the ears 380 of the paper box and the cover 390 to interfere with each other when the ear folding mechanism 120 performs the ear folding operation.

[0053] In some embodiments of the present application, reference Figure 1 and Figure 2 The ear folding mechanism 120 includes two ear folding components 160, and the rotating shaft of the turntable 100 is accommodated between the two ear folding components 160. The two ear folding components 160 can move relatively close to each other so that the two ears 380 are folded toward the opening of the paper box.

[0054] It can be understood that due to the narrow space between the positioning component 110 and the rotation axis of the turntable 100, the present application arranges two folding ear components 160, and there is an avoidance space between the two folding ear components 160. The avoidance space can avoid the rotation axis of the turntable 100, thereby solving the problem that the space between the positioning component 110 and the rotation axis of the turntable 100 is narrow, which makes it difficult to arrange the folding ear mechanism 120 structure. Therefore, the space on the turntable 100 can be fully utilized.

[0055] In addition, the two ear folding components 160 fold the two ears 380 of the paper box toward the opening of the paper box respectively. The two ear folding components 160 perform the ear folding work at the same time, which can improve the ear folding efficiency of the paper box.

[0056] In some embodiments of the present application, reference Figure 2 The ear folding mechanism 120 also includes a first moving component, which includes a moving frame 170 and a first power member 180 for driving the moving frame 170 to move. The moving frame 170 is located on the side of the positioning component 110 at the rotating axis of the turntable 100 away from the box sealing station. The two ear folding components 160 are connected to the moving frame 170 to move closer to the opening of the paper box. It should be noted that the first power member 180 can use a cylinder as a power source, which is not specifically limited here.

[0057] It can be understood that, in this embodiment, a movable frame 170 and a first power member 180 are provided, and the first power member 180 is used to drive the movable frame 170 to approach the opening of the paper box. The movable frame 170 can move along the length direction of the paper box, and the length direction of the paper box can be consistent with the Y-axis in the horizontal direction. The movable frame 170 moves the folding ear assembly 160 to the ear folding position, so that the folding ear assembly 160 can fold the ears accurately. In addition, the first power member 180 is used to drive the movable frame 170 away from the opening of the paper box, so that the folding ear assembly 160 is away from the positioning assembly 110, so as to avoid interference between the positioning assembly 110 and the folding ear assembly 160 when the positioning assembly 110 rotates with the turntable 100.

[0058] In addition, the movable rack 170 is located on the side of the rotating axis of the turntable 100 away from the positioning assembly 110 at the box sealing station. The space on the side of the rotating axis of the turntable 100 away from the positioning assembly 110 is larger. This makes it easier to arrange the movable rack 170, and a larger movable rack 170 can be designed, which is beneficial to improving the stability of the movable rack 170.

[0059] In some embodiments of the present application, reference Figure 3 and Figure 4The ear folding assembly 160 includes a cantilever 210, a first push block 220 connected to the end of the cantilever 210, and a second power member 200 that drives the cantilever 210 to move. The cantilever 210 extends along the radial direction of the turntable 100 and toward the positioning assembly 110 near the box sealing station. The first push block 220 is used to push an ear 380 of the paper box. It should be noted that the second power member 200 can use a cylinder as a power source, which is not specifically limited here.

[0060] It can be understood that, in this embodiment, a cantilever 210, a first push block 220 and a second power member 200 are provided, and the second power member 200 is used to drive the cantilever 210 to move, so that the first push block 220 follows the cantilever 210 to move, and the first push block 220 can move along the width direction of the paper box, and the width direction of the paper box can be consistent with the horizontal X-axis, so that the first push block 220 folds the ear 380 of the paper box toward the opening of the paper box, and the second power member 200 does not need to be directly connected to the first push block 220, so that the second power member 200 can be away from the positioning assembly 110, thereby reducing the space occupied around the positioning assembly 110 and facilitating the arrangement of the folding cover mechanism 130, the folding tongue mechanism 140 and the covering mechanism 150 around the positioning assembly 110.

[0061] In some embodiments of the present application, reference Figure 3 and Figure 4 , and also includes a bracket 230, which is located between the two folding ear assemblies 160, and the folding cover mechanism 130, the folding tongue mechanism 140 and the covering mechanism 150 are installed on the bracket 230.

[0063] In some embodiments of the present application, reference Figure 3 and Figure 4 The cover folding mechanism 130 includes a cover folding block 240 and a third power member 250 for driving the cover folding block 240 to move. The cover folding block 240 is used to push the cover plate 390. It should be noted that the third power member 250 can use a cylinder as a power source, which is not specifically limited here.

[0064] It can be understood that, in this embodiment, a folding block 240 and a third power member 250 are provided, and the third power member 250 is used to drive the folding block 240 to move. The folding block 240 can move along the thickness direction of the paper box. The thickness direction of the paper box can be consistent with the vertical Z axis. The folding block 240 can push the cover plate 390 so that the cover plate 390 is folded toward the opening of the paper box, which facilitates the subsequent folding tongue mechanism 140 to accurately fold the tongue piece 400 toward the opening of the paper box.

[0065] In some embodiments of the present application, reference Figure 3 and Figure 4 , and also includes a box suction mechanism 260, which is located on the side of the positioning component 110 away from the supporting surface. The box suction mechanism 260 includes a suction component 270 and a fourth power member 280 that drives the suction component 270 to move. The suction component 270 is used to suck the side wall of the paper box connected to the cover plate 390.

[0066] It can be understood that in this embodiment, the box suction mechanism 260 is provided, and the box suction mechanism 260 is located at the side of the positioning assembly 110 at the box sealing station away from the support surface. In this way, the box suction mechanism 260 has a larger layout space, which is convenient for the installation and fixation of the box suction mechanism 260.

[0067] In addition, the present application sets up a suction component 270 and a fourth power member 280, and uses the fourth power member 280 to drive the suction component 270 to move. The suction component 270 can move along the thickness direction of the paper box. The thickness direction of the paper box can be consistent with the vertical Z axis. The suction component 270 sucks the side wall of the paper box connected to the cover plate 390 to prevent the side wall of the paper box from sinking in, so as to facilitate the subsequent tongue 400 to be accurately inserted into the opening of the paper box.

It should be noted that the fifth power member 300 can use a cylinder as a power source, which is not specifically limited here.

[0069] It can be understood that, in this embodiment, the folding tongue member 290 and the fifth power member 300 are provided, and the fifth power member 300 is used to drive the folding tongue member 290 to move. The folding tongue member 290 can move along the length direction of the paper box, and the length direction of the paper box can be consistent with the Y-axis in the horizontal direction. The folding tongue member 290 utilizes the first abutment plate to abut against the tongue piece 400, so that the tongue piece 400 is folded toward the opening of the paper box, and the second abutment plate abuts against the cover plate 390 to push the cover plate 390 toward a vertical state, so that the subsequent closing mechanism 150 can push the cover plate 390 so that the tongue piece 400 can be accurately inserted into the opening of the paper box.

[0070] In some embodiments of the present application, reference Figure 3 The covering mechanism 150 includes two covering components 310, and the two covering components 310 are distributed on opposite sides of the folding tongue mechanism 140 along the supporting surface. The covering component 310 includes a second push block 320 and a sixth power member 330 that drives the second push block 320 to move. The second push block 320 is used to push the cover plate 390. It should be noted that the sixth power member 330 can use a cylinder as a power source, which is not specifically limited here.

[0071] It can be understood that in this embodiment, two covering components 310 are arranged, and the two covering components 310 are distributed on opposite sides of the folding tongue mechanism 140 along the supporting surface. Such an arrangement makes the covering component 310 close to the middle position in the thickness direction of the paper box, and by providing a second push block 320 and a sixth power member 330, the sixth power member 330 is used to drive the second push block 320, and the second push block 320 can move along the length direction of the paper box. The length direction of the paper box can be consistent with the Y-axis in the horizontal direction. The second push blocks 320 of the two covering components 310 synchronously push the cover plate 390, so that the tongue piece 400 can be smoothly inserted into the interior of the paper box.

[0072] In summary, the working principle of a carton sealing device of a cartoning machine of this embodiment is as follows:

[0073] First, before the paper box sealing operation of the positioning component 110, it will pass through the guide 340. The guide 340 uses the first guide plate 350 and the second guide plate 360 ​​to limit the position of the cover plate 390 of the paper box. After that, the first power member 180 is used to drive the movable frame 170 close to the opening of the paper box. The movable frame 170 can move along the length direction of the paper box. The length direction of the paper box can be consistent with the horizontal Y-axis. The movable frame 170 moves the folding ear component 160 to the ear folding position to facilitate the precise ear folding of the ear folding component 160.

[0074] Then, the second power member 200 is used to drive the cantilever 210 to move, so that the first push block 220 moves with the cantilever 210. The first push block 220 can move along the width direction of the paper box, and the width direction of the paper box can be consistent with the horizontal X-axis, so that the first push block 220 folds the ear 380 of the paper box toward the opening of the paper box.

[0075] Next, the third power member 250 is used to drive the folding block 240 to move. The folding block 240 can move along the thickness direction of the paper box. The thickness direction of the paper box can be consistent with the vertical Z axis. The folding block 240 can push the cover plate 390 so that the cover plate 390 is folded toward the opening of the paper box.

[0076] In addition, the fourth power member 280 is used to drive the suction component 270 to move. The suction component 270 can move along the thickness direction of the paper box. The thickness direction of the paper box can be consistent with the vertical Z axis. The suction component 270 sucks the opposite side wall of the paper box side wall connected to the cover plate 390 to prevent the side wall of the paper box from sinking inward.

[0077] Next, the fifth power member 300 is used to drive the folding tongue member 290 to move. The folding tongue member 290 can move along the length direction of the paper box. The length direction of the paper box can be consistent with the horizontal Y-axis. The folding tongue member 290 uses the first abutment plate to abut against the tongue piece 400, so that the tongue piece 400 is folded toward the opening of the paper box.

[0078] Finally, the sixth power member 330 is used to drive the second push block 320, and the second push block 320 can move along the length direction of the paper box. The length direction of the paper box can be consistent with the horizontal Y-axis. The second push blocks 320 of the two covering assemblies 310 synchronously push the cover plate 390, so that the tongue 400 is smoothly inserted into the interior of the paper box to complete the box sealing operation.
