Description

Technical Field

[0001] This utility model relates to the field of egg carton automation technology, and in particular to an automatic egg carton assembly device. Background Technology

[0002] Paper pulp egg cartons are containers for storing and transporting eggs made from recycled paper pulp or plant fibers (such as bagasse and bamboo fiber) through a molding process. The production process typically includes pulping, molding, drying, and pressing. They are naturally biodegradable and recyclable, making them a type of green packaging.

[0003] Egg carton structures consist of an upper lid and a lower lid. The upper lid is generally used for labeling and advertising, while the lower lid is used to hold the eggs. Existing egg cartons are generally made with the upper and lower lids as one piece, while some are made with separate upper and lower lids. In the production of separate egg cartons, the connection between the upper and lower lids is applied manually before they are connected. This production method is time-consuming and labor-intensive.

[0054] As can be seen, the clearance groove on the second support member 333 can avoid the third support member 335, so that it will not interfere when receiving the upper or lower cover, ensuring the normal operation of each component of the extraction assembly 33 and improving the stability and reliability of the equipment operation.

[0055] In one embodiment, the conveying assembly 20 includes a motor, a drive wheel, a driven wheel, a transmission belt, a first limiting member 21, and a second limiting member 22. The motor is mounted on the frame 10, and the drive end of the motor is connected to the drive wheel. The drive wheel is located at one end of the conveying path, and the driven wheel is located at the other end of the conveying path. The transmission belt is sleeved on the drive wheel and the driven wheel. The first limiting member 21 extends along a first direction and is mounted on the transmission belt.

The second limiting member 22 is configured to press down the connecting part of the lower cover after it has been sprayed with glue and bring it close to the connecting part of the upper cover so that the pressing assembly 50 can press the connecting part of the upper cover and the lower cover together.

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

[0057] Specifically, the second limiting member 22 includes a mounting plate 230 and a limiting plate 231. The mounting plate 230 is vertically arranged, with its top end set on the frame 10. The limiting plate 231 is set at the bottom end of the mounting plate 230 and is inclined downward to flip the connecting part on the lower cover downward to approach the connecting part on the upper cover.

[0058] As can be seen, the motor-driven drive wheel and driven wheel of the conveying component 20 convey the egg carton through the transmission belt. The structure is simple and stable. The first limiting member 21 limits the transport of the egg carton, ensuring that the transport surface of the upper or lower cover abuts against the transmission belt, preventing the egg carton from shifting or falling during transport. The second limiting member 22 presses down the connecting part of the lower cover after it has been sprayed with glue and brings it close to the connecting part of the upper cover before the pressing station 82, so that the connecting parts of the upper and lower covers are in a suitable position, which facilitates the pressing component 50 to perform the pressing operation, thereby improving the pressing effect and efficiency.
