Description

Technical Field

[0001] The utility model relates to the technical field of glue injection, in particular to a glue injection device for producing easy-open lids. Background Art

[0002] An easy-open lid is formed through processes such as blanking and stamping. Its definition is a lid with a pre-etched scoring line of a certain depth and riveted with a pull ring that can be safely torn along the scoring line when opened, and is mostly used for the lids of aluminum cans for packaging in the food processing industry. A traditional aluminum can is formed by pressing an easy-open lid and a side wall panel. To ensure the sealing performance between the easy-open lid and the side wall panel, before the formed easy-open lid is pressed with the can body, a glue injection device is required to apply a layer of sealant in the circumferential groove of the lid body.

[0003] When the glue is placed in the glue bucket in a stationary state for a long time, the glue is likely to solidify. Manual stirring will cause certain losses and result in a great waste of manpower and material resources. At the end of the work, the nozzle needs to be removed to clean the glue inside. Usually, the disassembly of the nozzle is rather troublesome. For this reason, a glue injection device for producing easy-open lids is proposed to solve the above problems. Summary of the Utility Model
