Description

Technical Field

[0001] The utility model relates to the field of self-aligning devices, in particular to a self-aligning device for the outer packaging film of products on a production line. Background Art

[0002] Product packaging is also the visual experience of consumers for products. It is the direct and main transmitter of product individuality and the direct manifestation of the enterprise image positioning. Good packaging design is one of the important means for enterprises to create profits. The visual and functional effects of product packaging directly affect the sales of products and the guarantee of product quality. The visual effect of packaging is more affected by the quality of packaging in addition to the influence of the appearance design factors of the packaging itself. The functional effect is affected by external environmental factors, which is the main cause caused by the quality of packaging. Due to the iterative upgrade of technology, in the last process of product production, modern enterprises, in order to protect products from being affected by the external environment, prevent problems such as damage and pollution of products during storage, sales, safety guarantee, handling, and transportation that affect product quality.

[0003] In the process of product packaging, most modern enterprises use automated production lines, and product packaging is automated. However, the quality of packaging depends on the precise cooperation of each component in the packaging process. During market research, it was found that the precise positioning and self-alignment of the packaging film for bagged products are the key factors for packaging quality. The actual situation on site is that in order to facilitate the replacement of the packaging film, the packaging film positioning brackets on site are all fixed structures that cannot be automatically adjusted. If the diameter or width of the packaging film exceeds the preset size range, it is necessary to replace or re-manufacture the positioning brackets. Moreover, the fixed-structure positioning brackets cannot be automatically adjusted. Once they are tilted, the quality of the product's outer packaging is unqualified. In addition, some equipment manufacturers do not consider the utilization rate of the packaging film. Some packaging films still have the remaining film that can be used to package dozens of products, but due to the inability to be automatically adjusted, they are forced to be discarded and replaced with new films, which not only causes waste, increases the production cost of enterprises, but also increases the workload.

[0004] Therefore, in view of the problem that the fixed - structure positioning bracket of the above - mentioned packaging film cannot be automatically adjusted, once it is tilted, the quality of the outer packaging of the product is unqualified, and the new film needs to be discarded and replaced, which not only causes waste, increases the production cost of the enterprise, but also increases the workload. A product outer packaging film automatic centering device can be designed and developed. It can automatically move up and down as the diameter of the film gradually becomes smaller during use, ensuring the maximum utilization rate of the film, reducing the unusable margin, automatically adjusting and selecting the appropriate packaging film size according to the width of the film required by the product, enabling the packaging film to move left and right to ensure that the packaging film always completely covers the product to be packaged, automatically adjusting to adapt to the width of the film to adapt to different film widths, and at the same time automatically adjusting the film to always be within the limited range of the package, thus ensuring the packaging quality of the product. Summary of the Invention

[0005] In order to overcome the problem that the fixed - structure positioning bracket of the packaging film cannot be automatically adjusted, once it is tilted, the quality of the outer packaging of the product is unqualified, and the new film needs to be discarded and replaced, which not only causes waste, increases the production cost of the enterprise, but also increases the workload.
