[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) This type of logistics packaging equipment places the cooked food after production on the conveyor belt for transportation by setting a lifting mechanism, etc. When the viewing angle sensor detects that it moves to the bottom of the mobile cover, the conveyor is stopped, and then the first motor is started. The rotation of the first motor drives the rotation of the first threaded rod, thereby driving the second movable plate to move upward, and then the third movable plate and the push rod are driven upward through the weighing mechanism, so that the push rod moves upward along the circular hole, can seal the circular hole, and lift the cooked food. At the same time, when the second movable plate moves upward, it drives the first rack to move upward synchronously, so that the gear is reversed. The clockwise rotation causes the second rack and the moving block to move downward, and at the same time, the second spring is compressed. When the moving block moves downward, the first moving plate is driven to move downward, and the moving cover is driven to move downward through the first reset mechanism. When the moving cover abuts against the top of the conveyor belt, the cooked food is covered. At the same time, the first spring is gradually compressed. At this time, the sliding plate moves downward along the heat preservation box, so that the cold air temporarily stored in the heat preservation box can be squeezed. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the cold air temporarily stored in the heat preservation box is squeezed and blown onto the surface of the cooked food through the blowing pipe, so as to pre-cool it. The cooling efficiency is improved. Then, the exhaust fan is started to absorb the hot air in the mobile hood through the exhaust hood and the exhaust pipe, and is cooled through the condenser. The cooled cold air passes through the blowing pipe and the blowing hood and is blown on the surface of the cooked food, thereby circulating and cooling the air in the mobile hood and blowing on the surface of the cooked food, improving the cooling efficiency and effect, making it cooler more fully, and thus ensuring the quality of subsequent packaging. After the cooling is completed, the exhaust fan is turned off. Then, the second movable plate is moved downward by the lifting mechanism, and the blowing hood and the top rod are driven to move gradually downward by the weighing mechanism. At this time, The first movable plate can move upward and reset under the action of the second spring. At this time, the first spring gradually resets, so that the sliding plate can move upward in the insulation box, thereby generating negative pressure in the insulation box. At the same time, the first one-way valve opens and the second one-way valve closes. At this time, the cold air remaining in the movable cover is sucked into the insulation box through the exhaust pipe for temporary storage, which avoids the waste of cold air and is more energy-saving and environmentally friendly. After the first spring is reset, when the first movable plate continues to move upward, it can drive the movable cover to move upward. At the same time, the cooled cooked food can fall on the conveyor belt. Then, the conveyor is started to continue to transport it.

[0015] (2) This type of logistics packaging equipment is provided with a weighing mechanism and a sorting mechanism. When cooling, the push rod lifts up the cooked food. At this time, the third sleeve rod moves downward along the third sleeve tube. At the same time, the third spring is compressed. The distance sensor detects the change in the distance of the third moving plate to determine the compression amount of the third spring, and then determines the weight of the cooked food, thereby facilitating online detection of the weight of the cooked food, which is more convenient and quick. After the cooling is completed, when the cooked food continues to be transported forward along the conveyor belt, it slides along the guide plate into the U-shaped plate. Then, the second motor is started. The movement of the second motor drives the movement of the U-shaped plate and the guide plate, so that the U-shaped plate is aligned with different placement slots on the movable plate in turn. Then, the cooked food can slide along the guide plate into the U-shaped plate and fall into the packaging box in the corresponding placement slot. The cooked food that does not meet the weight requirement is pushed down from the conveyor belt for collection. When all the packaging boxes in the placement slot are filled with cooked food, the movable plate can be moved to the packaging machine for packaging operation, thereby improving the efficiency and quality of packaging.

After the cooling is completed, the exhaust fan 18 is turned off, and then the second movable plate 24 is moved downward by the lifting mechanism 4, and the blowing hood 15 and the top rod 26 are driven to gradually move downward by the weighing mechanism 8. At this time, the first movable plate 23 can be moved downward at the first The first spring 203 is gradually reset, so that the sliding plate 702 can move upward in the heat preservation box 701, thereby generating negative pressure in the heat preservation box 701. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the cold air remaining in the movable cover 14 is sucked into the heat preservation box 701 through the exhaust pipe 703 for temporary storage, thereby avoiding the waste of cold air and being more energy-saving and environmentally friendly. After the first spring 203 is reset, when the first movable plate 23 continues to move upward, it can drive the movable cover 14 to move upward. At the same time, the cooled cooked food can fall on the conveyor belt 1101. Then, the conveyor 11 is started to continue to convey it. At the same time, during cooling, the push rod 26 pushes up the cooked food. At this time, the third sleeve rod 801 moves downward along the third sleeve tube 802. At the same time, the third spring 803 is compressed. The distance sensor 804 detects the change in the distance of the third moving plate 25 to determine the compression amount of the third spring 803, and then determines the weight of the cooked food, so that the weight of the cooked food can be detected online, which is more convenient and quick. After cooling is completed, when the cooked food continues to be transported forward with the conveyor belt 1101, it slides along the guide plate 902 into the U-shaped plate 901, and then, the second motor 1004 is started. The movement of the second motor 1004 drives the movement of the U-shaped plate 901 and the guide plate 902, so that the U-shaped plate 901 is aligned with different placement slots 1202 on the movable plate 1201 in turn. Then, the cooked food can slide along the guide plate 902 into the U-shaped plate 901 and fall into the packaging box in the corresponding placement slot 1202. The cooked food that does not meet the weight requirement is pushed down from the conveyor belt 1101 for collection. When all the packaging boxes in the placement slots 1202 are filled with cooked food, the movable plate 1201 can be moved to the packaging machine 12 for packaging operations, thereby improving the efficiency and quality of packaging.
