Filter bag packaging machine fixing device for fixing labels on filter paper

Abstract

The invention provides a filter bag packaging machine fixing device for fixing labels on filter paper. The fixing device comprises a label cutting-off mechanism, an annular mounting frame and a mounting ring located on the inner side of the mounting frame; the inner side of the mounting ring is provided with a rotating shaft in the central axial direction; the rotating shaft is fixedly connected with the inner wall of the mounting ring; the mounting ring and the rotating shaft rotate intermittently in the central axial direction of the rotating shaft jointly; the mounting ring is provided witha plurality of stations at intervals in the circumferential direction; each station is provided with two sliding pins; and the outer side of the mounting ring is further provided with a wire windingassembly, a folding device, a heat sealing assembly I, a slitting cutter assembly and a heat sealing assembly II. The surface lines are subjectedto length determining through intermittent rotation ofthe mounting ring and the wire winding assembly, the production precision of products can be ensured, on the premise of ensuring normal use of consumers, the purposes of saving resources and reducingproduction cost are better achieved, and meanwhile, since cotton threads form small thread loops at joints with the filter paper, the connection strength can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tea bag packaging machines, and in particular relates to a fixing device for fixing labels on filter paper used in filter bag packaging machines. Background technique [0002] The known tea bag packaging machine belongs to the category of "vertical-bag forming-filling and sealing machine", which is composed of a quantitative feeder, a main transmission box, a label cotton thread conveying device, a tea bag heat sealing device, a tea bag conveying device, and an outer bag paper conveying device. device, outer bag registration device, outer bag forming mechanism, manipulator, outer bag sealing mechanism, finished product output trough, preset group counting device, machine base, etc. The quantitative feeder is composed of a conical hopper and a quantitative adjustment device, and the crushed tea is put into the quantitative feeder. The inner bag filter paper is placed on the inner bag paper conveying devic...

AI Technical Summary

Problems solved by technology

When the start button is pressed and the machine starts to work automatically, granular tea leaves or similar materials will fall into the filter which has been folded in half and placed between the two inner bag heat-sealing rollers to be sealed through the discharge nozzle of the quantitative feeder. In the bag, the bag mouth and the labeled cotton thread sent by the hanging claw are heat-sealed together by the heat-sealing roller, and cut into "labeled teabags" by the scissors under the inner bag heat-sealing device. However, The existing outer bag forming mechanism has the following disadvantages when fixing the cotton thread and the label on the filter paper: First, the existing forming mechanism cannot flexibly adjust the length of the cotton thread, and cannot flexibly switch to meet the needs of customers with different brewing methods To meet the needs of different customers; secondly, the production efficiency of the existing forming mechanism is generally not high, and the connection strength and method between the cotton thread, the label and the inner bag become the technical bottleneck of the existing packaging machine to develop at a higher speed, which cannot adapt to large Demand for orders and mass production
