[0057] like Figure 14 and Figure 15 As shown, multiple mesh holes 1025 are provided on both the lower frame 1023 and the upper frame 1021 of the strip cage to ensure that the strips 103 in the strip cage 102 are fully exposed to the external high-temperature steam during the sterilization process. Spring clips 1024 are provided on both sides of the upper frame 1021 of the strip cage to ensure that the lower frame 1023 of the strip cage can be clamped and positioned by the spring clips 1024 when the second lifting mechanism 93 lifts the lower frame 1023 to the bottom side of the upper frame 1021.

[0058] The bag cage conveyor line 9 in this embodiment is used to carry the lower frame 1023 of the bar bag cage. The two-axis manipulator 7 grabs the bar bag box 101 filled with bar bags and transfers it to the lower frame 1023 of the bar bag cage on the bag cage conveyor line 9. The second lifting mechanism 93 lifts the lower frame 1023 of the bar bag cage upward through the through hole 92 to the lower side of the upper frame 1021 of the bar bag cage, and then fastens the lower frame 1023 of the bar bag cage to the lower side of the upper frame 1021 of the bar bag cage through the fastening mechanism 104, thereby forming a closed structure of the bar bag cage 102, so that the bar bag box 101 filled with bar bags is enclosed in the bar bag cage 102, ensuring that the bar bags will not scatter during the sterilization and cooling and drying process. Among them, there are two second lifting mechanisms 93, one of which is used to transfer the lower frame 1023 of the strip cage from the servo conveyor chain 10 to the cage conveyor line 9; the other second lifting mechanism 93 is used to lift the lower frame 1023 of the strip cage on the cage conveyor line 9 to the servo conveyor chain 10.

[0059] Preferably, if Figure 11As shown, the locking mechanism 104 is disposed above the second lifting mechanism 93. The two locking mechanisms 104 are respectively disposed corresponding to the buckles 1022 at both ends of the strip cage upper frame 1021. The locking mechanism 104 includes a fifth driving member 1041 and a push block 1043. The output end of the fifth driving member 1041 is vertically connected to the push block 1043. The fifth driving member 1041 is disposed on the side of the servo conveyor chain 10. The push block 1043 is pushed toward the inside of the servo conveyor chain 10 and can press the upper side of the buckle 1022, causing the buckle 1022 to unlock the strip cage 102 and open the strip cage 102. Smooth rods 1042 are disposed on both sides of the fifth driving member 1041. One end of the smooth rod 1042 is connected to the push block 1043, and the other end is slidably connected to the side of the servo conveyor chain 10 to stabilize the pushing process of the push block 1043.

[0060] Preferably, if Figure 13 As shown, the second lifting mechanism 93 includes a sixth driving member 931, a top block 932, a fixing frame 933, and a support rod 934. The sixth driving member 931 is vertically arranged and its output end is connected to the top block 932. Two support rods 934 are respectively arranged on both sides of the sixth driving member 931 and their top ends are connected to the top block 932. The fixing frame is a horizontal plate. The fixing frame 933 is arranged parallel to the top block 932, and the support rods 934 and the sixth driving member 931 are connected to the fixing frame 933. The sixth driving member 931 can drive the top block 932 to lift upward. The shape of the top block 932 is adapted to the shape of the through hole 92, so that the top block 932 can pass through the through hole 92 to the top of the strip bag cage holding plate 91.

[0061] The first driving member 52 , the second driving member 852 , the third driving member 262 , the fourth driving member 83 , the fifth driving member 1041 and the sixth driving member 931 are all cylinders.
