The inclined bottom feeding tank 2 is a rectangular tank with an open top, used for storing and discharging the gas absorbent. A square hole 21 for discharging the gas absorbent is arranged in the middle of the bottom end of the vertical plate on the longer side of the inclined bottom feeding tank 2, the height of the square hole 21 is greater than twice the diameter of the gas absorbent, the width of the square hole 21 is greater than 1.5 times the diameter of the gas absorbent, and the tablet is ensured not to be blocked.

[0023] The sorting device 3 comprises a lifting guide groove 31 connected to the square hole 21, a tensioning wheel 7 is arranged at the bottom of the connection between the lifting guide groove 31 and the inclined bottom feeding tank 2, a supporting wheel 8 is arranged at the bottom of the connection between the lifting guide groove 31 and the conveying device 5, a cam 9 is arranged on the elongated shaft of the supporting wheel 8 and is connected to the recycling device 4 and serves as a driving roller, the conveying device 5 comprises a main guide groove 51 connected to the lifting guide groove 31 and a discharge groove 52, a driving wheel 10 is arranged at the bottom of the connection between the main guide groove 51 and the discharge groove 52, a main conveying belt 6 is sleeved on the outer wall close to the tensioning wheel 7, the supporting wheel 8 and the driving wheel 10, and the main conveying belt 6 is located inside the main guide groove 51 and the lifting guide groove 31 and runs above the guide groove bottom plate, the guide groove bottom plate supports the main conveying belt 6 to ensure that the main conveying belt 6 can stably and efficiently convey the articles in the groove. The driving wheel 10 and the supporting wheel 8 are in the same horizontal position, the angle between the line connecting the tensioning wheel 7 and the supporting wheel 8 and the horizontal plane is 10-45 degrees, and the tensioning wheel 7 can be adjusted in the horizontal position to ensure that the main conveying belt 6 sleeved on the three wheels maintains appropriate tension. Since the recycling device 4 is a mirror image of the structure after being turned over 180° with the conveying device 3, the end close to the inclined bottom feeding tank 2 of the recycling device 4 is higher than the lifting guide groove 31, ensuring that the recycled gas absorbent enters the main conveying belt 6 under the action of gravity. The driving wheel 10 is controlled by a motor and provides power for the entire system, and the motor is controlled by a controller to adjust the start-stop and rotation speed of the driving wheel 10. The lifting guide groove 31 provides guidance for the gas absorbent discharged from the square hole 21, and the height difference between the tensioning wheel 7 and the supporting wheel 8 is set so that the main conveying belt 6 located in the lifting guide groove 31 climbs in a slope shape, and the gas absorbent placed flat on the main conveying belt 6 can be smoothly lifted, while the gas absorbent not placed flat will roll down and be reordered to enter the next round of feeding state.

[0024] The first gap 33 is arranged on the side plate close to the lifting guide groove 31 of the recycling device 4 and away from the inclined bottom chute 2, and the second gap 34 is arranged close to the inclined bottom chute.

The recycling tension wheel 12 is arranged at the bottom of the recycling device 4 close to the inclined bottom chute 2 and is located above the left of the tension wheel 7. The recycling conveying belt 13 is sleeved on the outer wall of the recycling tension wheel 12 and the recycling transmission wheel 11, so as to reversely transport the gas absorbent and reenter the sorting device 3.

[0026] The transmission device 5 further comprises the photoelectric counting device 53 arranged on the main guide groove 51. The photoelectric counting device 53 is composed of a counter and a photoelectric opposite switch. When the gas absorbent passes through, the photoelectric opposite switch is blocked, a signal is sent to the controller, and the counter counts increases by 1. After the gas absorbent is counted by the photoelectric counting device 53, it is filled to the specified position of the heat insulation pipe through the discharge chute 52. When the counting quantity reaches the set quantity, the photoelectric counting device 53 controls the motor to stop rotating, the filling is stopped, and the next filling instruction is waited.

[0027] Working principle: the gas absorbent stored in the inclined bottom hopper 2 flows out from the square hole 21, is transported into the sorting device 3 through the main conveying belt 6 and the lifting guide groove 31, and is filled into the specified position of the adiabatic tube through the light-electricity counting device 53 after being counted; the gas absorbent which is not laid flat is pushed out from the first gap 33 of the sorting device 3 by the sorting baffle 32, slides into the gap of the corresponding position of the recycling device 4 through the transition chute 14 under the action of gravity, and is reversely transported into the recycling device 4, re-enters the sorting device 3 through another gap of the recycling device 4, another transition chute and the second gap 34 of the sorting device 3 to be transported again. When the counting quantity reaches the set quantity, the light-electricity counting device 53 controls the motor to stop rotating, the filling of the feeding is stopped, and the next feeding instruction is waited.
