Problems solved by technology

At the same time, manufacturers have to spend a higher price to purchase related equipment and build new factories, which not only results in a decline in the utilization rate of equipment, but also increases the production cost of packaging materials and reduces the cost-effectiveness of consumers' purchases.

specific Embodiment example 2

[0043] A welding process for laser welding packaging drums, comprising:

[0044] Product loading and positioning and pressing: After the steel plate raw materials to be welded are folded and docked, they are fixed on the welding workbench with clamping fixtures. Among them, the steel plate to be processed adopts butt welding, that is, the steel plate to be welded does not need to be overlapped when coiled. The butt welding method makes the welding seam smooth, avoids the occurrence of high welding seam, and ensures that there will be no dead corners when the end curling of the packaging barrel after welding is formed, so as to avoid packaging leakage accidents.

[0045] Resetting and opening of the laser: move the laser head of the laser to the starting position, turn on the shielding gas and the laser, the laser head starts to move, and welds the two ends of the rolled steel plate together. Among them, since no welding material is used in the laser welding process, the steel...

Abstract

The invention provides a laser welding packing barrel and a welding technology thereof. The welding technology of the laser welding packing barrel comprises the following steps of feeding a product, positioning and laminating the product, resetting and starting a laser, shutting off the laser and discharging the product. The welding technology has the beneficial effects that no high welded joints are generated by setting laser parameters and replacing traditional overlap welding with butt welding to ensure that no dead angles are left at the end during hemming of the packing barrel to cause liquid leakage; the width of the welded joints is kept to be about 3mm, so that the appearance of the packing barrel is not affected; sheet materials used according to the technology are steel plates subjected to roll coating by special manufactures, so that spray coating is not needed after welding; no benzene hydrocarbon is generated; and environment pollution is avoided. The packing barrel formed by welding according to the welding technology comprises an upper cover body, a barrel body and a lower cover body, wherein the lower cover body is connected to the bottom end of the barrel body in a fastening closed manner; the upper end opening of the barrel body is connected to the upper cover body in a fastening closed manner or is detachably connected to the upper cover body, and the fastening closed connection and the detachable connection respectively correspond to the packaging of solid products and liquid products; meanwhile, a coating printed at the outer side of the packing barrel has an anti-fake label so as to facilitate fair competition and protect the rights and interests of manufactures and consumers.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a laser welding packaging bucket and a welding process thereof. Background technique [0002] In today's market, most products require packaging. Product packaging is like human clothes. Different packaging will bring different visual experiences to consumers. Exquisite external packaging can successfully stimulate consumers' desire to buy. The packaged product is not only beautiful in appearance, but also can avoid damage to the product during transportation as much as possible, especially for flowing liquid substances that require external packaging before long-distance transportation; secondly, necessary packaging can also delay product spoilage and so on. [0003] There are many kinds of packaging materials, among which metal packaging materials have high transportation safety, good wear resistance and high strength. With the increasing awareness of environmental protecti...
