Seaming mechanism of can manufacturing machinery

Abstract

The invention discloses a seaming mechanism of can manufacturing machinery. The seaming mechanism of the can manufacturing machinery comprises a guide piece, a plurality of rolling groups, a plurality of seaming shaft groups and a plurality of seaming mold groups, wherein the guide piece is arranged on a main shaft, provided with an annular guiding part and around the periphery of the main shaft; The rolling groups are located at the periphery of the main shaft in same space and are respectively provided with rolling shafts and rolling heads arranged axial end of the rolling shaft; the plurality of seaming shaft groups are adjacent to the corresponding rolling shafts, wherein each seaming shaft group is provided with a first seaming shaft, a second seaming shaft, a first guided part and a second guided part, and respectively bridged between the axial end of each seaming shaft and the guiding part; and the plurality of seaming mold groups are respectively adjacent to the corresponding rolling heads, each seaming mold group is provided with a column-shaped first seaming mold head and a column-shaped third seaming mold head, a first seaming arm part, a column-shaped second seaming mold head, wherein the first column-shaped first seaming mold head and the column-shaped third seaming mold head are in parallel to the first seaming shafts around the column shaft and are adjacently corresponding to the rolling heads, the first seaming arm part is bridged and fixedly connected among the other axial ends of the first seaming mold head, the third seaming mold head and the first sealing shaft, the column-shaped second seaming mold head is in parallel to the second seaming shaft around the column shaft and is adjacently corresponding to the rolling heads, and the second seaming arm part is bridged and fixedly connected between the other axial ends of the second seaming mold head and the second seaming shaft.

Description

technical field [0001] The invention relates to can-making machinery, in particular to a rolling-sealing mechanism of the can-making machine. Background technique [0002] In the field of metal can making technology, usually the tubular can body and the bottom cover are first rolled and sealed into a cylindrical semi-finished product, and after filling the semi-finished product with appropriate content, the top cover is rolled and sealed on the cylindrical shape. The opening end of the semi-finished product is completed, and the seaming mechanism used to combine the lid body with the can body is generally constructed by winding the can body around the can body tube axis through the seam sealing die. On the peripheral side, the joint parts between the cover body and the can body are crimped sequentially to achieve the effect of sealing. [0003] Since the number of rolls between the tank body and the lid directly affects the compressive strength of the tank, there is a conve...

Problems solved by technology

[0004] The technical content disclosed in this new patent can achieve the good combination effect of making the tank body have seven layers of seaming. A single seaming die head and a single roller, but there are repeated components and resulting in excessive volume defects, especially when there is a processing requirement for high-speed seaming, these structures will not be able to perfectly achieve seven The processing procedure of layer seaming
