[0028] As Figures 2 to 4 shown in the embodiment, a conveying assembly 8 for conveying food to be packaged is also arranged in the sterile box 7, the conveying assembly 8 comprises a hollow box 81 detachably arranged in the sterile box 7, two guide plates 82 respectively arranged at left and right ends of the inner side of the sterile box 7 and the bottom of which is connected with the top end surface of the hollow box 81, the left and right opposite surfaces of the two guide plates 82 are connected with the inner side of the connecting port 83 arranged on the top end surface of the hollow box 81, and the connecting port 83 is used for conveying food to be packaged;

[0029] A conveying plate 84 is slidably arranged in the hollow box 81, the conveying plate 84 can slide along the inner side of the hollow box 81 to push the food in the conveying hole 85, and a discharge port 86 for discharging food is arranged at the left end of the bottom of the hollow box 81 and is staggered with the connecting port 83, and a second motor 810 is fixedly arranged in the hollow box 81;

[0030] An auxiliary mechanism 87 for assisting in discharging food is arranged above the discharge port 86;

[0031] A conveying hole 85 corresponding to the connecting port 83 is arranged at the top left end of the conveying plate 84, the distance from the inner right end of the conveying hole 85 to the left end surface of the conveying plate 84 is greater than the inner width of the conveying hole 85, and a strip-shaped tooth hole 88 is arranged on the side surface of the conveying plate 84;

[0032] A second half gear 89 engaged with the strip-shaped tooth hole 88 is arranged in the strip-shaped tooth hole 88, the second half gear 89 is engaged with the inner upper and lower end surfaces of the strip-shaped tooth hole 89, so that the second half gear 89 drives the conveying plate 84 to reciprocate in the hollow box 81 by cooperating with the inner upper and lower end surfaces of the strip-shaped tooth hole 89, and the inner ring of the second half gear 89 is connected with the output shaft of the second motor 810;

[0033] The guide plate 82 extends inwardly and downwardly from top to bottom, and the inner bottom of the guide plate 82 is aligned with the inner side of the connecting port 83, so as to guide the food to be conveyed into the connecting port 83 through the guide plate 82;

[0034] The inner width of the discharge port 86 is greater than the inner width of the conveying hole 85, so as to stably discharge the food in the conveying hole 85 into the discharge port 86;

[0035] In the embodiment, a groove is arranged at the right end of the rear end surface of the conveying plate 84, the groove is through the inner side of the strip-shaped tooth hole 88, and the inner side of the groove completely covers the second motor 810, so as to reduce the weight of the conveying plate 84 and facilitate the arrangement of the second motor 810 in the groove;

[0036] Specifically, in use, the opening and closing of the first motor 31, the second motor 810 and the micro electric push rod 871 are programmed and controlled by the PLC electric control box 4. The food to be packaged is stored in the sterile box 7. The first motor 31 drives the first half gear 32 to rotate. When the teeth of the first half gear 32 contact the transmission gear 33, the transmission gear 33 is driven to rotate by a corresponding angle. The transmission gear 33 drives the right end transmission roller 34 to rotate synchronously. The transmission roller 34 drives the transmission belt 2 to rotate by a corresponding amplitude. When the first half gear 32 rotates to the plane opposite to the transmission gear 33, the transmission belt 2 stops rotating. When the first half gear 32 continuously rotates, the transmission belt 2 is driven to rotate intermittently. Then the food packaging box is placed between the two positioning partitions 5. The packaging box moves intermittently under the action of the transmission belt 2 until the packaging box moves to the bottom of the sterile box 7.

[0037] At the same time, the food in the sterile box 7 passes through the connecting port 83 into the conveying hole 85. The second motor 810 is started to drive the second half gear 89 to rotate. The second half gear 89 cooperates with the inner side of the strip-shaped tooth hole 88 to drive the conveying plate 84 to move left and right in the hollow box 81. When the conveying plate 84 moves to the left, it drives the conveying hole 85 and the food in the conveying hole 85 to convey to the left. When the conveying plate 84 moves to the left, the right end of the conveying plate 84 blocks the connecting port 83. At this time, the food in the connecting port 83 cannot fall into the hollow box 81. When the conveying hole 85 moves to the left end of the inner side of the hollow box 81, the conveying hole 85 is aligned with the discharge port 86. The food in the conveying hole 85 falls down, passes through the discharge port 86 and the bottom of the inner side of the sterile box 7, and enters the packaging box, to complete the automatic packaging of the food. The filling process of the food does not need manual operation, reduces the risk of bacterial infection caused by manual operation, and realizes the packaging of sterile food.

[0038] As shown in Figure 5 In the present embodiment, the auxiliary mechanism 87 includes a micro electric push rod 871 fixedly connected to the left end of the top of the hollow box 81 and located below the guide plate 82, and a push plate 872 arranged in the hollow box 81 and located vertically above the discharge port 86. The piston rod of the micro electric push rod 871 passes through the top end surface of the hollow box 81 and is connected to the push plate 872. The shape and size of the push plate 872 correspond to the shape and size of the inner side of the conveying hole 85. The micro electric push rod 871 is electrically connected to the PLC electric control box 4.

[0039] In the present embodiment, a receiving groove 873 is formed in the left end of the inner top end surface of the hollow box 81. When the piston rod of the micro electric push rod 871 is in a retracted state, the push plate 872 is completely retracted into the receiving groove 873. The push plate 872 is conveniently received through the receiving groove 873, and the conveying plate 84 is conveniently moved below the push plate 872.

[0040] Specifically, the micro electric push rod 871 is started to drive the push plate 872 to move downward, and the push plate 872 pushes the food in the conveying hole 85 downward to assist in discharging the food and prevent the food from adhering to the conveying hole 85, thereby improving the discharging efficiency of the food.

[0041] The above merely describes preferred examples of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
