Automatic box sealing height adjusting device of automatic box sealing machine

Abstract

The invention discloses an automatic box sealing height adjusting device of an automatic box sealing machine. The automatic box sealing height adjusting device comprises a box sealing upper machine frame lifting device for enabling a box sealing upper machine frame to move up and down, and an automatic box sealing height detecting device; the box sealing upper machine frame lifting device comprises a transmission shaft rotationally connected with the upper end of a portal frame; a chain wheel is fixedly connected with the transmission shaft; a smooth rod is fixedly connected with stand columnson the two sides of the portal frame; the lower end of the portal frame is fixedly connected with a speed reduction motor; a speed reduction motor chain wheel is connected with the chain wheel through a chain; an upper support plate and a lower support plate are fixedly connected with the box sealing upper machine frame; ends of the upper support plate and the lower support plate are fixedly connected with a supporting plate; a sliding sleeve and a chain clamp are fixedly connected with the supporting plate; the sliding sleeve is slidably connected with the smooth rod; the chain clamp and thechain are tightly connected; the automatic box sealing height detecting device comprises detecting brackets which are in butt-joint with the front end of a box sealing lower machine frame; rollers are connected between the detecting brackets; the rollers are in drive connection with a motor through a driving chain; and the rollers are in drive connection with a transmission chain. The box sealingupper machine frame of the automatic box sealing height adjusting device can be effectively and accurately positioned, the box sealing time is greatly shortened, and the box sealing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of carton packaging for industrial factory products, and in particular relates to a device for automatically adjusting the sealing height of a fully automatic case sealing machine. Background technique [0002] As a kind of packaging equipment for industrial factory products, the automatic sealing machine is an indispensable equipment for improving efficiency, saving manpower, realizing industrial automation, and assembly line operations. However, the lifting of the upper frame of the existing automatic sealing machine adopts Driven by the cylinder, due to the structural limitations of the cylinder, the upper frame has been pressing the carton for sealing. At this time, the position of the cylinder piston is in the middle of the cylinder barrel, and the air pressure in the upper chamber of the cylinder is greater than that in the lower chamber. Otherwise, the cartons cannot be pressed tightly to effectively seal the c...

[0002] As a kind of packaging equipment for industrial factory products, the automatic sealing machine is an indispensable equipment for improving efficiency, saving manpower, realizing industrial automation, and assembly line operations. However, the lifting of the upper frame of the existing automatic sealing machine adopts Driven by the cylinder, due to the structural limitations of the cylinder, the upper frame has been pressing the carton for sealing. At this time, the position of the cylinder piston is in the middle of the cylinder barrel, and the air pressure in the upper chamber of the cylinder is greater than that in the lower chamber. Otherwise, the cartons cannot be compressed and sealed effectively. After the cartons are sealed, no matter whether there are still or not the same cartons, they will immediately rise to the top of the cylinder.

Because the air pressure in the upper and lower chambers of the piston in the cylinder is different, the piston cannot be effectively positioned when it moves up or down, and the gas is compressible and expandable, so it cannot be effectively positioned. Therefore, this fully automatic seal No matter whether the cartons of the same specification or not, the carton machine cannot seal the cartons continuously. It must repeat: "Rise to the top, descend to seal the cartons when there are cartons, and rise to the top after sealing. Only after the first one is sealed can it be sealed." The action of "next", so there is a requirement for the time interval of sealing the carton. When the first carton is being sealed, the second carton cannot enter, and the cartons cannot be sealed continuously at the same time, resulting in slow sealing speed and repeated invalid sealing actions. It is difficult to realize automation on the automatic assembly line
