Horizontal sealing top knife and sealing knife guard board friction limiting device used for packing machine

Abstract

The invention discloses a horizontal sealing top knife and sealing knife guard board friction limiting device used for a packing machine. The horizontal sealing top knife and sealing knife guard board friction limiting device used for the packing machine comprises an upper girder, the upper girder is connected with a sealing knife guard board through horizontal knife hoisting bolts, sealing knife guard board lifting nickel-plated compressed springs are arranged between the upper girder and the sealing knife guard board, friction copper boards are installed on the inner side of the sealing knife guard board, cutting-resisting sensing supports are fixed to the two sides of the middle section of the upper girder, a horizontal knife is arranged at the bottom of the sealing knife guard board, and installation blocks are arranged at the upper portion of the sealing knife guard board. The horizontal sealing top knife and sealing knife guard board friction limiting device used for the packing machine can achieve continuous sealing and cutting of products, and the firmness of seals is improved; in addition, the friction copper boards are easy and convenient to install, the horizontal sealing top knife and sealing knife guard board friction limiting device is convenient to clean and maintain, accessories are convenient to replace, and the stability and overall working efficiency of a horizontal sealing device are greatly improved.

Description

technical field [0001] The invention belongs to the field of packaging machines, and in particular relates to a friction limiting device for a horizontal sealing upper knife sealing knife guard plate used for the packaging machine. Background technique [0002] At present, most of the horizontal sealing systems of packaging machines in the same industry in the market use heat pipes to heat the horizontal sealing knife body. The horizontal sealing knife body is connected to the upper beam of the sealing knife by lifting bolts. The installation block of the knife guard is connected to the guide post, and the nickel-plated compression spring is used to let the guide post slide in the copper sleeve to realize the elastic lifting of the knife guard. If the gap of the copper sleeve is too small, the guards on both sides are easy to get stuck. If the gap is too large, the guards on both sides are easy to shake from side to side during sealing and cutting, which will affect the seal...

AI Technical Summary

Problems solved by technology

If the gap between the copper sleeves is too small, the guards on both sides are likely to be stuck. If the gap is too large, the guards on both sides are easy to shake from side to side during sealing and cutting, which will affect the sealing and cutting effect.

The failure rate of this structure is high, and manual troubleshooting is required during the sealing and cutting process, which affects the continuity and stability of the overall product shrinkage
