Summary
The beverage setters on the market are mostly suitable for round beverage bottles made of PET material. This article aims at the occurrence of no labels, card marks, high marks, low marks, crooked marks, joint marks, left and right tilts, and neck marks during the square bottle set. In addition to various defects such as poor centering rate, the square beverage bottle labeling machine was upgraded and designed, and the optimization research was carried out from the aspects of improved label centering rate, upgrade of mark knife, upgrade of steam nozzle of mark shrink furnace, and upgrade of cutter cutter plate positioning. . The results show that after the upgrade of the standard set machine, the pass rate of the square bottles in the square bottle reached 99%, the center rate of the finished product reached 95%, and the detection rates of high and low marks, burrs marks, crook marks, and crack marks all reached <1%, which improved production efficiency. , saving costs. This study provides a reference basis for upgrading the labeling machine for square bottle covers.
Research background
The labeling machine is a general packaging machine and is widely used in packaging lines such as water, juice, tea beverages, and milk-containing beverages. It can automatically complete the delivery of labels into bottles and labeling. There are many forms of labeling machines that can match various container shapes and materials, such as round bottles, square bottles, oval bottles, curve bottles, plastic bottles, metal bottles, glass bottles, etc. The applicable label materials are mainly PVC, PET, OPS, etc., with a label thickness of about 0.035mm to 0.08mm, a label height of about 25mm to 210mm, and a label inner diameter of about 127mm to 254mm.
In the extremely fierce homogeneous beverage market, whether outer packaging can attract attention and stand out is one of the key factors in product sales. Currently, the most suitable round beverage bottle is the round beverage bottle. Due to its diversity and novelty of the set label, the square bottle has formed a personalized logo of product, which has enhanced consumers' desire to buy and opened up for beverage manufacturers. A wider channel. However, due to its irregular appearance, square bottles are prone to problems such as no mark, clamp mark, high mark, low mark, crooked mark, joint mark, left and right tilt label, poor neck mark and centering rate. The common detection method is manual detection, operation The employee picks after the high-speed online light inspection or the set of marks is completed. This method has problems such as low efficiency, high missed inspection rate, and high labor costs.
As one of the equipment with high technical content of back-stage packaging, the packaging machine is widely used in the food industry, but there are few relevant documents currently disclosed. Yang Haiming has designed a 360° all-round detection system for beverage bottles to improve the accuracy of the beverage bottle cover. Li Dewei designed and transformed the control system of the labeling machine from multiple dimensions, increasing the speed of the labeling of the bottle. Hang Weiming uses double row differential conveying to move the label bottle forward and rotate simultaneously, achieving uniform heating of each outline of the long label on the bottle, breaking through the limitations of electric heat shrink furnaces that can only be used in the production of short label bottles. This article designs and studies the upgrade plan of square bottle labeling machine to solve the problems of poor labeling and low production efficiency in production, in order to provide beverage manufacturers with reference to optimize labeling technology.
In conclusion
The consumption demand in my country's beverage market continues to develop. In order to improve production efficiency, enterprises will increase their demand for high-speed production lines, and the standard machine industry is also developing rapidly and diversified. This paper studies the upgrade plan of square bottle labeling machine to solve the problems of poor labeling and high labor costs in production. On the marking machine equipment, a crease column device is installed to expand the inner diameter of the label; improve the marking knife, change the one-shaped cutting head to a cross cutting head, and change the subscript guide column from cylindrical to square, so that the label is smooth Put it into the bottle body; install a driver for the fixed nozzle, improve the fixed nozzle into a nozzle that can be rotated and ejected in 360° direction, so that the shrink label is heated evenly and the shrink label is completely reduced; make a cutter plate centering adjustment tool to accurately mark the position to avoid Burrs and personnel injuries occurred. The labeling machine is verified according to the above design, which greatly reduces the defect rate of the square bottle label, high and low standards, crack marks, burr marks, crook marks, crook marks, crook marks, and crook marks, and the detection rate is all less than 1%. Due to the reduction of the defective rate, the speed of the set-up is rapidly improved, and the stable set-up speed is increased from 350 bottles/min to 410 bottles/min. This study upgraded the process of matching square bottle labeling and achieved great results with small changes, providing certain reference value for the improvement of square bottle labeling equipment.
