[0053] Specifically, two avoidance grooves are formed on the avoidance groove so as to avoid the two support rods when the two support rods support the upper cover or the lower cover.

[0054] It can be seen that the avoidance groove on the second support member 333 can avoid the third support member 335, so that interference does not occur when receiving the upper cover or the lower cover, ensuring the normal operation among the components of the extraction assembly 33 and improving the stability and reliability of the equipment operation.

[0055] As an implementation manner, the conveying assembly 20 includes a motor, a driving wheel, a driven wheel, a transmission belt, a first limiting member 21 and a second limiting member 22. The motor is arranged on the frame 10. The driving end of the motor is connected to the driving wheel. The driving wheel is arranged at one end of the conveying channel. The driven wheel is arranged at the other end of the conveying channel. The transmission belt is sleeved on the driving wheel and the driven wheel. The first limiting member 21 extends along the first direction and is arranged on the transmission belt.

The second limiting member 22 is arranged on the conveying path and is located before the pressing station 82. The second limiting member 22 is configured to press down the connecting part of the lower cover after spraying glue and approach the connecting part of the upper cover so as to facilitate the pressing assembly 50 to press the connecting parts of the upper cover and the lower cover.

[0056] Specifically, the first limiting member 21 includes a first pressing strip 220 and a second pressing strip 221. The first pressing strip 220 and the second pressing strip 221 are respectively arranged at intervals above the transmission belt. The first pressing strip 220 is configured to press the upper cover against the upper surface of the transmission belt. The second pressing strip 221 is configured to press the lower cover against the upper surface of the transmission belt.

[0058] It can be seen that the motor of the conveying assembly 20 drives the driving wheel and the driven wheel, and the egg tray is conveyed through the transmission belt. The structure is simple and stable. The first limiting member 21 limits the transportation of the egg tray to ensure that the transportation surface of the upper cover or the lower cover abuts against the transmission belt, preventing the egg tray from shifting or falling during the conveying process; the second limiting member 22 presses down and approaches the connecting portion of the upper cover of the lower cover sprayed with glue before the pressing station 82, so that the connecting portions of the upper cover and the lower cover are in a suitable position, facilitating the pressing operation of the pressing assembly 50 and improving the pressing effect and efficiency.

[0066] It can be seen that the detection member 61 of the screening assembly 60 can accurately judge the connection situation between the upper cover and the lower cover and distinguish between qualified products and defective products. The sixth driving member 62 cooperates with the automatic door 64 to transport the qualified egg cartons to the collection assembly 70, realizing the automatic classification and transportation of qualified products and defective products, and improving the production efficiency and the level of product quality control.

[0067] As an implementation manner, the collection assembly 70 includes a seventh driving member 71 and a push plate 72. The seventh driving member 71 is arranged on one side of the collection station 84, and the seventh driving member 71 is configured to push the egg cartons at the collection station 84 to the manual extraction place through the push plate 72.

The eighth driving member 73 is arranged between the collection station 84 and the screening station 83. The driving end of the eighth driving member 73 is connected to the first receiving plate 74 and the second receiving plate 75. The eighth driving member 73 is configured to drive the first receiving plate 74 and the second receiving plate 75 to approach or move away from each other simultaneously along the second direction. The first receiving plate 74 and the second receiving plate 75 are configured to carry the qualified egg cartons conveyed from the screening station 83 to the first receiving plate 74 and the second receiving plate 75 by the screening assembly 60, and place the stacked qualified egg cartons on the collection station 84.

[0071] Specifically, the eighth driving member 73 includes a first guide rail, a second guide rail, a first air cylinder, and a second air cylinder. The first guide rail extends along the second direction and is disposed above the egg tray pushing end of the pushing channel.
