[0026] As mentioned above, in the field of carton packaging, for example, in the process of carton packaging of cigarettes in the tobacco industry, the bottom of the carton is usually sealed manually, then the items (such as cigarettes) are packed, and finally the top of the carton is sealed. With the continuous development of science and technology, mechanical carton sealing devices for carton sealing have emerged. However, there are many shortcomings in the existing mechanical carton sealing devices.

[0027] In view of this, the present disclosure provides a mechanical carton sealing device for sealing the bottom of a carton, which can not only make carton packaging more automated but also has a simple and compact structure.

[0028] For the convenience of description, a carton sealing device 10 for bottom sealing of a carton according to an embodiment of the present disclosure is taken as an example for description.

[0029] Reference Figures 1 to 4 , which respectively show a perspective view, a front view, a left view and a top view of a carton sealing device 10 for bottom sealing of a carton according to an embodiment of the present disclosure. The carton sealing device 10 is particularly suitable for bottom sealing of a parallelepiped carton 20, especially a rectangular carton 20.

[0030] The box sealing device 10 for sealing the bottom of a carton according to the present disclosure may include a conveying mechanism 100. See in particular Figure 4The conveying mechanism defines a conveying channel, and the conveying channel may include a folding area 110 and a sealing area 120 in sequence along the conveying direction. A folding mechanism 200 may be arranged in the folding area 110, and a sealing mechanism 300 may be arranged in the sealing area 120.

[0031] The conveying mechanism 100 may include two parallel tracks 140, and a roller 141 and a conveyor belt 142 that can be driven by a drive motor 143 may be arranged in each track 140. Figure 3 The track 140 may be, for example, formed of a channel profile, so that the conveyor belt 142 in each track 140 can contact the side of the carton 20, so that the two conveyor belts 142 can jointly clamp the carton 20. The conveyor belt 142 may be, for example, configured as a conveyor belt. The conveyor belt 142 is conveyed on the inner side of the track 140 by a driving motor 143 and a roller 142, so that the carton 20 can move with the conveyor belt 142.

[0032] Thus, due to the conveying of the carton 20 by the conveying mechanism 100, the folding of the bottom of the carton 20 by the folding mechanism 200, and the sealing of the bottom of the carton 20 by the sealing mechanism 300, the bottom of the carton 20 can be sealed mechanically and automatically. In addition, due to the partition design along the conveying channel and the simple implementation of the conveying mechanism 100, the sealing device 10 according to the present disclosure has a simple and compact structure.

[0033] According to some embodiments of the present disclosure, see in particular Figure 1 and Figure 6 The conveying mechanism 100 may further include a track spacing adjustment mechanism 150. The track spacing adjustment mechanism 150 may include two clamping mechanisms respectively arranged on the outer side of each track. Each clamping mechanism may include a clamping support 151, a driving cylinder 152 disposed on the clamping support 151, a telescoping device 153 disposed laterally on the driving cylinder 152, a clamping block 154 disposed at the free end of the telescoping device 153, and a silicone pad 155 disposed on the free surface of the clamping block 154, wherein the driving cylinder 152 can drive the telescoping device 153 and thus can drive the clamping block 154 to telescopically move.

[0034] The distance between the two rails 140 can be adjusted according to the size of the carton 20 by the rail spacing adjustment mechanism 150, so that the carton sealing device 10 according to the present disclosure can be adapted to cartons of different sizes. In addition, the conveying mechanism 100 can be driven more stably.

[0035] According to some embodiments of the present disclosure, see in particular Figure 1 , Figure 2 and Figure 4 The hemming mechanism 200 may include a supporting slide 210, a hemming guide 220, an upstream hemming assembly 230 and a lateral hemming clamp 240.

[0036] The supporting slideway 210 may be configured as a slide bar extending along the conveying direction.

[0037] The folding guide 220 may be configured as an arc-shaped member that bends and extends downwardly from the upstream end of the support slide 210 in the conveying direction toward the upstream, so that when the carton 20 is conveyed in the conveying direction, for example, the short side of the carton 20 may be guided to fold.

[0038] The upstream hemming assembly 230 may include a pivot arm 232 that can pivot around a pivot axis 231 and a push rod 233 disposed at a free end of the pivot arm 232. Thus, the upstream hemming assembly 230 can fold, for example, the short side of the carton 20.

[0039] The side hem clamp 240 includes two converging guide rods, see Figure 4 This can guide, for example, two long sides of the carton 20 to fold.

[0040] Thus, the folding mechanism 200 can be realized in a simple and compact structure.

[0041] In this regard, it is advantageous to refer in particular to Figures 1 to 3 , the support slide 210 can be disposed on an adaptable base 250. Similarly, the upstream hemming assembly 230 can also be disposed on an adaptable base 250. The hemming guide 220 can be connected to the support slide 210 or formed in one piece with the support slide 210. Similarly, the lateral hemming clip 240 can be connected to the support slide 210 or formed in one piece with the support slide 210.

[0042] Thus, the structure of the folding mechanism 200 can be further simplified.

[0043] According to some embodiments of the present disclosure, see in particular Figure 1 and Figure 5 The glue sealing mechanism 300 may include a pressure roller 310, a glue sealing roller 320 and a rotation stopper 330. The glue sealing roller 20 may be configured to apply the adhesive tape to the bottom of the carton 20, and the pressure roller 310 may be configured to press the surface of the carton across the gap of the carton to achieve a stable press fit. The rotation stopper 330 may be configured to limit the rotation of the glue sealing roller 320.

[0044] Thus, the sealing mechanism 300 can be realized with a simple structure.

[0045] According to some embodiments of the present disclosure, see in particular Figure 1 and Figure 4 The conveying channel of the conveying mechanism 100 may further include a buffer area 130 located downstream of the sealing area 120 along the conveying direction. A buffer mechanism 400 may be arranged in the buffer area.

[0046] Through the buffer area 130 and the corresponding buffer mechanism 400, cartons with sealed bottoms can be kept in the area to wait for further processing, thereby making the carton sealing device 10 according to the present disclosure more automated.

[0047] According to some embodiments of the present disclosure, see in particular Figure 1 and Figure 4 The buffer mechanism 400 may include a roller conveyor 410 and a carton stopping mechanism 420. The carton stopping mechanism 420 may be located in a downstream end region of the roller conveyor 410.

[0048] Thus, the buffer mechanism 400 can be realized with a simple structure.

[0049] According to some embodiments of the present disclosure, see in particular Figure 1 and Figure 3 , the roller conveyor 410 may be supported by a separate support base 430 .

[0050] Therefore, the structure of the box sealing device 10 according to the present disclosure can be simplified.

[0051] In the operation of the carton sealing device 10 according to the present disclosure, for example, after the carton formed by the robot clamp is in place, the conveyor belt 8 inside the track 140 can clamp the carton 20 and drive the carton 20 to move along the conveying direction, wherein the track 140 can be adjusted by the track spacing adjustment mechanism to achieve the clamping adjustment of the carton 20, so as to be suitable for cartons of different widths. The folding guide 220 can first fold the downstream short side of the carton 20, and then the upstream folding assembly 230 can fold the upstream short side of the carton 20, and then the lateral folding clamp 240 can fold the two long sides of the carton 20. After the folding is completed, the carton 20 is transported to the glue sealing area 120, and the bottom of the carton 20 is glued at the position of the glue sealing roller 320, and is pressed and stabilized at the position of the pressure roller 310. Finally, the carton 20 is transported to the buffer area 130, where the carton 20 is stopped by the carton stop mechanism 420 and buffered.

[0052] It can be seen that the box sealing device 10 according to the present disclosure can realize automatic folding and bottom sealing tape, and has a simple and compact structure.

[0053] The features disclosed in this application document may be important and may be implemented for the implementation of the embodiments in different design solutions not only individually but also in any combination. The present disclosure is not limited to the embodiments shown, but includes or extends to all technical equivalents that may fall within the effective scope of the attached claims.
