It will be appreciated that both the inner box 70 and the outer bag 80 may be paper, which is advantageous for cost reduction. Further, in order to improve the aesthetic property after the tea is packaged, the sizes of the inner box 70 and the outer bag 80 are very close, in the embodiment of the invention, the inner box 70 and the outer bag 80 are cuboids, in fig. 3, a is the length of the inner box 70, b is the width of the inner box 70, and h is the height of the inner box 70; in fig. 4, a is the length of the outer bag 80, B is the width of the outer bag 80, and H is the height of the outer bag 80; wherein 1cm < A-a < 2cm,1cm < B-B < 2cm,50cm < H-H < 100cm. Specifically, in the examples of the present invention, A was 55cm, B was 25cm, H was 130cm, a was 53.8cm, b was 23.2cm, and h was 46cm.

Further, please refer to fig. 1 to fig. 6, the box grabbing mechanism 20 includes a moving assembly 21, an opening device 23, and a first connecting member 22, the first connecting member 22 is connected to the isolation plate 13, the moving assembly 21 includes a first moving member 211 and a second moving member 212, one end of the first moving member 211 is slidably connected to the first connecting member 22, and the other end is slidably connected to the second moving member 212; the end of the second moving part 212 remote from the first moving part 211 is connected to the spreading means 23. Further, the opening device 23 is used for grabbing the inner box 70, specifically, the opening device 23 includes two opening arms 231, one end of each of the two opening arms 231 is used for grabbing the inner box 70, and the other end is slidably connected with the second moving member 212 so that the two opening arms 231 can move close to or away from each other.

It will be appreciated that, in order to avoid damage to the inner cartridge 70 after the two opening arms 231 are fully opened, the distance between the two opening arms 231 when the two opening arms 231 are fully opened should be set according to the size of the inner cartridge 70.

Specifically, the two expanding arms 231 and the second moving member 212 are slidably connected to the clamping rail 232 through the guide groove 2122, the guide groove 2122 is disposed on one side of the second moving member 212 close to the expanding device 23, and the clamping rail 232 is disposed on the two expanding arms 231. Further, the cross section of the clip rail 232 is polygonal, and the shape of the guide groove 2122 corresponds to that of the clip rail 232, so that the two opening arms 231 can move relatively or oppositely through the cooperation of the clip rail 232 and the guide groove 2122, and the stable connection between the two opening arms 231 and the second moving member 212 can be ensured.

It can be understood that the process of the inner case 70 being grasped by the opening device 23 is that the two opening arms 231 are close to each other to make the two opening arms 231 not completely open or contact each other, then the two opening arms 231 are extended into the inner case 70, and then the two opening arms 231 are opened to make the two opening arms 231 completely open, the inner case 70 can be grasped by an outward force applied when the two opening arms 231 are opened, and the inner case 70 can be grasped and simultaneously be grasped and the inner case 70 can be opened, so that the side wall of the inner case 70 is prevented from being concave. Further, in order to avoid damage to the inner box 70 due to large force application in the process of opening the two opening arms 231 to grab the inner box 70, the flexible piece 2310 is arranged on the opposite side of the two opening arms 231, the flexible piece 2310 is arranged at one end of the two opening arms 231 extending into the inner box 70, and the flexible piece 2310 can be formed by encapsulating the opening arms 231 and can also be of a structure such as a silicone pad.

It can be understood that the moving direction of the opening device 23 is the moving direction of the first moving part 211 and the second moving part 212.

Further, the first moving member 211 of the present invention moves in a first direction f1 shown in fig. 5, i.e., moves laterally, and the second moving member 212 moves in a second direction f2 shown in fig. 5, i.e., moves longitudinally, where the first direction and the second direction are perpendicular to each other. It is understood that the specific directions of the first direction and the second direction can be adjusted in actual production.

Furthermore, a first sliding part 221 and a second sliding part 222 arranged on two sides of the first sliding part 221 are arranged on the first connecting part 22, a matching structure which is in sliding fit with the first sliding part 221 and the second sliding part is arranged on the first moving part 211, and the first connecting part 22 and the first moving part 211 are in sliding connection through the matching of the first sliding part 221 and the second sliding part 222 with the matching structure on the first moving part 211, so that the first moving part 211 can move stably along the first sliding part 221 and the second moving part 212 in the first direction.

It can be understood that the first sliding member 221 disposed at the middle position plays a role of balance stability, which can make the process of sliding the first moving member 211 along the second sliding member 222 more stable.

Optionally, the first sliding part 221 may be a guide rail, and the second sliding part 222 may be a balance column, or both the first sliding part 221 and the second sliding part 222 are guide rails, and when the structural types of the first sliding part 221 and the second sliding part 222 are changed, the matching structure on the first moving part 211 is correspondingly changed. In addition, the number and specific positions of the first sliding member 221 and the second sliding member 222 can also be adjusted according to actual requirements.

Furthermore, one end of the first moving member 211, which is far away from the first connecting member 22, is provided with a third sliding member 2111 and an expansion link 2112, the second moving member 212 is provided with a matching portion 2121 matched with the third sliding member 2111 and the expansion link 2112, one end of the matching portion 2121 is slidably connected with the third sliding member 2111, and the other end of the matching portion 2121 is connected with the expansion link 2112, and the matching portion 2121 is controlled to move along the third sliding member 2111 through expansion and contraction of the expansion link 2112, so that the second moving member 212 moves towards the second direction.
