Description

Technical Field

[0001] The utility model relates to the technical field of full-automatic packaging machines, in particular to a full-automatic packaging machine for riveted nuts. Background Art

[0002] Riveted nuts are used in fields such as mechanical processing. After the production of the riveted nuts is completed, they need to be packaged in a quantitative manner to facilitate their transportation. In the prior art, a fully automatic packaging machine is used to automatically package the riveted nuts.

[0003] That is, after the bottom end of the plastic film is sealed by the heat sealing equipment, the feeding equipment feeds a certain amount of rivet nuts into the inside of the plastic film after the bottom end is sealed. However, during this process, the sealed end of the plastic film is prone to cracking, causing the rivet nuts inside it to directly fall into the external environment.

[0004] The main reason for the above problems is that after the bottom end of the plastic film is sealed by heat sealing, its heat-sealed end needs a period of cooling to completely harden, and the above method is to add rivet nuts inside the plastic film when the heat-sealed end has not yet completely hardened. A large number of rivet nuts have a certain weight themselves. Therefore, after a large number of rivet nuts fall into the plastic film, they will directly impact the sealed end of the plastic film, causing the heat-sealed end of the plastic film that has not yet completely hardened to crack, making it impossible to effectively pack the rivet nuts. To address the above problems, we propose a fully automatic packaging machine for rivet nuts. Utility Model Content
