L-shaped sealing mechanism in banknote plastic sealing and packaging machine

Abstract

The invention discloses an L-shaped sealing mechanism in a plastic packaging integrated machine for banknotes. The L-shaped sealing mechanism structurally comprises an L-shaped tool rest with heat seal and a cut-off tool, a tool apron matched with the tool rest and an opening / closing driving mechanism for the tool rest and the tool apron and is characterized in that the tool rest and the tool apron are respectively positioned on an upper guide plate and a lower guide plate, wherein the upper and lower guide plates are limited on a guide pin group for connecting and positioning a base plate and a top plate by means of guide bushes and form degrees of freedom of relatively sliding with guide pins; gear and rack intermediate driving mechanisms which are symmetrically arranged on two sides of the upper guide plate and the lower guide plate are positioned on the base plate by means of a T-shaped frame; a piston rod of an air cylinder on the top plate is fixedly connected with the upper guide plate. During work, the air cylinder drives the upper guide plate to do linear motion by means of the piston rod, and drives the lower guide plate and the upper guide plate to do united or separated motion by means of the gear and rack intermediate driving mechanisms, so the L-shaped tool rest and the tool apron are driven to be opened or closed to realize the sealing and the cutting of packaging films. The L-shaped sealing mechanism has the advantages of uniformity in pressure, smooth cut, firm sealing opening, high plastic packaging efficiency and good sealing effect.

Description

technical field [0001] The invention belongs to the field of packaging equipment, and relates to the improvement of the sealing mechanism in the plastic sealing packaging machine, in particular to the improvement of the sealing mechanism in the device for wrapping and packaging based on the film plastic sealing material, and is especially suitable for the banknote plastic sealing and packaging integrated machine. Background technique [0002] In the process of RMB circulation, packaging thousands of banknotes into bundles is a relatively heavy and meticulous work in the daily business work of banks and other financial institutions. In the prior art, banknote binding machines are used to bundle banknotes in three or five ways, which often causes damage to the banknotes, and cannot completely prevent the drawing, and is easy to be damp and mildewed during storage and transportation; while using a banknote plastic packaging machine, Banknotes can be completely packaged, tightly...
