When different sizes or shapes of ice cream containers 296 need to be adapted, the knob 49 is rotated to drive the bidirectional threaded rod 42 to rotate, and the bidirectional threaded rod 42 drives the sliding block 43 to move. Since the sliding block 43 is connected to the two brackets 45 through the connecting rod 44, the sliding block 43 moves to simultaneously push the brackets 45 to move towards or away from each other, thereby changing the distance between the two T-shaped plates 46, so that they can be adjusted according to different models and sizes of the ice cream container 296 to achieve reliable guiding effect.

Since the driving bevel gear 393 is engaged with the driven bevel gear 394, the driven bevel gear 394 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the half gear 33 to rotate. Since the rack 36 is engaged with the half gear 33, the rack 36 drives the closing plate 35 to move downward, so as to close the entrance of the ice-cream container 296, and the cold air in the box 1 will not leak from the entrance. When it is needed to open the entrance, the third motor 391 continues to rotate to drive the half gear 33 to rotate, so that the half gear 33 is disengaged from the rack 36. The spring 38 drives the closing plate 35 to move upward, so as to open the entrance of the ice-cream container 296. Finally, when the ice-cream container 296 enters the box 1, it is guided by the T-shaped plates 46 on both sides, and is pushed by the rollers 47 to move to the middle of the conveying belt 294, so that the ice-cream container 296 can always be in the middle position of the conveying belt 294 to be optimally cooled and sterilized.
