Adjusting mechanism for thin film packaging machine and longitudinal sealing force arm

Abstract

The invention discloses an adjusting mechanism for a thin film packaging machine and a longitudinal sealing force arm. The adjusting mechanism is arranged between a packaging machine body and the longitudinal sealing force arm. The adjusting mechanism comprises a fixing base, an adjusting block, a screw rod and nuts matched with the screw rod. The fixing base and the adjusting block are fixed to the packaging machine body and the longitudinal sealing force arm respectively. The fixing base and the adjusting block are each correspondingly provided with an outward-vertical U-shaped through groove. The screw rod is vertically arranged inside the U-shaped through grooves in the fixing base and the adjusting block. The upper end of the fixing base, the lower end of the adjusting block and the portion, between the fixing base and the adjusting block, of the screw rod are each provided with a nut. The adjusting mechanism has the beneficial effects that stress applied to the adjusting mechanism when longitudinal sealing force arm is inclined can be effectively released, and deformation of the screw rod is avoided; and the longitudinal sealing force arm can be conveniently adjusted to ascend and descend by rotating the nuts. The adjusting mechanism is simple in structure and convenient to use and has the good practicability.

Description

technical field [0001] The invention relates to the technical field of thin film packaging machines, in particular to a longitudinal sealing force arm of the thin film packaging machine. Background technique [0002] The longitudinal sealing force arm of the film packaging machine is mainly used to adjust the distance between the upper and lower stop rods of the film pressing lever to adapt to the film packaging of different thicknesses and specifications. The adjustment mechanism of the existing longitudinal sealing force arm of the film packaging machine is a T type. The threaded rod, the T-shaped threaded rod passes through the through hole on the fixed block fixed on the packaging machine body, and is engaged in the internal thread adjustment hole on the lever arm, and the T-shaped threaded rod is rotated to adjust the force arm relative to the fixed The position of the block; in the process of adjusting the height of the longitudinal seal, when first loosening the elast...

Problems solved by technology

[0002] The vertical sealing arm of the film packaging machine is mainly used to adjust the distance between the upper and lower levers of the film pressing lever to adapt to film packaging of different thicknesses and specifications. The existing adjustment mechanism of the vertical sealing arm of the film packaging machine is a T-shaped Threaded rod, T-shaped threaded rod passes through the through hole on the fixed block fixed on the body of the packaging machine, and bites into the internal threaded adjustment hole on the force arm, by rotating the T-shaped threaded rod to adjust the force arm relative to the fixed The position of the block; in the process of adjusting the height of the longitudinal seal, when the elastic bolt fixed on one side of the longitudinal seal arm is first loosened, the other side of the longitudinal seal arm will be tilted, because the T-shaped threaded rod for adjusting the longitudinal seal is fixed on the In the fixed block and the internal thread adjustment hole, therefore, the stress generated after the tilting of the longitudinal sealing force arm is concentrated on the joint between the T-shaped threaded rod and the force arm, which will easily lead to deformation of the T-shaped threaded rod and make it unusable. The force arm is bulky and difficult to replace. It requires the cooperation of multiple people to complete it, which affects production efficiency.
