Description

Technical Field

[0001] This utility model relates to the field of egg carton automation technology, and in particular to a multi-position automatic hot melt adhesive spraying 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] The egg carton structure consists of an upper cover and a lower cover. The upper cover is generally used for labeling and advertising, while the lower cover is used to hold the eggs. The upper and lower covers are separate and connected. During the transportation of the upper and lower covers to various workstations on the conveyor device, the transport surface of the upper cover is surface a, and the transport surface of the lower cover is surface b. The upper cover has a connecting surface c on one side along its length, and the lower cover has a connecting part d on one side along its length. The upper and lower covers are connected by spraying adhesive on the connecting part d, then flipping the connecting part d downwards to approach the connecting surface c, and finally connecting the connecting surface c and the connecting part d by a clamping device.

[0004] In the current pulp egg carton manufacturing process, the connecting part d is still applied with glue manually, and then the connecting part d is connected to the connecting surface c, which results in low production efficiency. Utility Model Content

The second limiting member 26 is located on the conveying path and before the first pressing station 61. The second limiting member 26 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 can press the connecting part of the upper cover and the lower cover together.

[0044] As can be seen, the motor 21 of the conveying assembly 20 drives the driving wheel 22 and the driven wheel 23, and the egg carton is conveyed through the transmission belt 24. The structure is simple and stable. The first limiting member 25 limits the transport of the egg carton, ensuring that the transport surfaces of the upper and lower covers abut against the transmission belt 24, preventing the egg carton from shifting or falling during transport. The second limiting member 26 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, so that the connecting parts of the upper and lower covers are in a suitable position, which facilitates the pressing operation of the first pressing assembly 40, improving the pressing effect and efficiency.
