Automatic can sealing machine multi-wheel seaming device

Abstract

The invention relates to an automatic can sealing machine multi-wheel seaming device, which comprises a spindle fixed on a spindle box, and a flywheel fixed on the spindle through a bearing. The lower end of the spindle is provided with a pressure head; shaft parts are arranged at the periphery of the flywheel; a seaming wheel arm, a swing arm, a seaming wheel and a guide rail wheel are positioned on the shaft parts; the seaming wheel is arranged at the free end of the seaming wheel arm and opposite to the side edge of the pressure head; a balance arm and a feeding wheel are arranged; the middle of the balance arm and the free end of the swing arm are positioned through pins, and two free ends are respectively provided with shafts to position the guide rail wheel and the feeding wheel; the side wall opposite to the guide rail wheel and the feeding wheel is provided with a guide rail and a feeding cam; and the shaft parts are provided with tension springs, so that the guide rail wheel and the feeding wheel are respectively pressed against the guide rail and the feeding cam inwards. The invention has the advantages that: the automatic can sealing machine multi-wheel seaming device is low in running noise, not easy to wear, convenient to assemble, disassemble and maintain, and the like.

Description

technical field [0001] The invention relates to can making equipment, in particular to a multi-round sealing device of an automatic can sealing machine for sealing the cover and the bottom of the tank body. Background technique [0002] In the can-making process, after the cylindrical can body is flanged, the bottom and cover of the can body need to be sealed to complete the production. The basic principle is that the sealing wheel rolls the front cover or bottom cover along the contour edge of the can body to achieve the purpose of fitting and sealing. At present, the movement track of the sealing wheel of the can sealing machine is repeated and fixed by the upper and lower rails, and the outer diameters of the two groups of eight sealing wheels are sequentially increased, which has a wide variety and complex structure. The manufacturing and assembly precision is extremely high. Once worn, it is difficult to repair and must be replaced. This complex structure is not conduc...

AI Technical Summary

Problems solved by technology

[0006] 1) The structure of the seaming head is complicated, which is quite troublesome in the process of assembly, disassembly and maintenance;

[0007] 2) The manufacturing and assembly precision requirements of guide rails and guide wheels are quite high. Once they are worn out, they must be replaced, resulting in an increase in the cost of maintenance and replacement;

[0008] 3) The installation needs to be manually polished and debugged, and the flatness of the mating surface cannot be guaranteed

[0009] 4) The outer diameter of the sealing wheel is too small and different, and there are many varieties, which is not conducive to production management;

[0010] 5) The sealing wheel is not adjustable, easy to wear and needs to be replaced frequently
