Introduce
Definition of wrap labeling machine
A wrap labeling machine is an automatic labeling machine that applies labels by wrapping the label around a product that needs to be labeled with a circular or cylindrical profile when the product is rotated around its own axis.
The importance of wrap labeling machines in the labeling industry
Labeling wrapped around the product is applied when the product needs to be labeled largely or completely covering the flat or curved surface of the label. With this form of labeling, the wrap labeling process has the following characteristics and importance:
Label coverage: With labels that are elaborately designed and have many details, applying wrap labels will help the label cover most or completely of the product, making the image on the label consistent and fully expressed, especially necessary for For some products that have strict requirements for information recorded on labels such as pharmaceuticals, chemicals, medical equipment, etc.
High efficiency compared to cost: Wrap labeling is a simple labeling process that involves few steps, so automatic labeling with a wrap labeling machine will help reduce investment costs, while labeling productivity and label quality will not change. change.
Various of: Rotary labelers can accommodate a variety of sizes, shapes, product materials and label materials, making them a reasonable choice for cost-constrained lines. needs to accommodate labeling for a variety of products or labels.
Types of wrap labeling machines
The wrap labeling machine uses pressure
Technology explanation: Pressure wrap labeling machine uses a conveyor belt with high friction and the effect of adding pressure using a mechanical mechanism such as compressed air, placed parallel to the label surface and the surface to be pasted. The input of this conveyor belt is glued to a part in the label belt, so when products enter this conveyor belt, they are rolled around its own axis and the label is wound and pressed onto the surface by friction and pressure. force of the upper conveyor belt.
Benefits and limitations of pressure labeling machines:
Reasonable price: This is often the most economical automatic labeling solution with few details and high productivity
Flexibility: The machine can easily adjust the size of the main operating parts, allowing the line to label products as well as labels with different shapes. In addition, the stickers used in the labeling line can be cut into shapes before being rolled into the sticker machine and the machine can still operate effectively.
Low accuracy: Unlike some other types of labeling machines, wrap labeling machines that use pressure can apply labels unevenly or cannot cover the entire surface of the product without the label pressing on itself.
Shape restrictions: The machine can only label products with round, cylindrical or similar profiles, placing products with rectangular or oval profiles on the line can make rolling the label onto the product difficult.
The wrap labeling machine has a glue dispenser
Technology explanation: Similar to other wrap labeling machines, the product is rotated on the main conveyor belt by a part that causes friction, but when it enters the friction part, the product is glued onto the labeling surface and is Apply the label to the surface immediately afterwards.
Benefits and limitations of glue-fed roll labeling machines
Low price: The roll labeling machine with its low price is an effective choice for small and medium-sized businesses, helping to optimize production costs and ensure competitiveness in the market.
Applicable to many sticker materials: Having an external glue dispenser allows the line to be applied to many different types of label materials as well as adhesive surfaces, in addition to reducing the input cost for the label roll.
Low accuracy: Using glue right on the line can cause the label to slip on the surface or cause glue leakage, excess glue, etc.
Shape restrictions: It is not possible to label products with special shapes such as rectangles, ovals, etc. or products that cannot rotate stably when entering the friction part.
Details of the wrap labeling machine
Product guidance department
Description: The product guide can be a linear guide by resizing the conveyor so that only one product can enter the labeling unit at a time, or it can be a Rotating guides like turntables pre-position the product
The importance of the product guide: with a stable and reliable guide, the labeling line will ensure maximum productivity and performance.
Labeling department
General introduction: there are many different types of labeling parts: pressure labeling units using compressed air, labeling units using heat, using electricity, using friction, etc.
Uses: The labeling department receives the label from the labeling department and then applies the label to the product on the line and applies the label by pressure, electromagnetism, heat, etc. securely to the product.
Labeling department
Technology description: Similar to other types of labeling machines, the labeling element of a wrap labeling machine includes a label roll and details that tension the label wire before the label is applied to the product. This part is often combined with a stepper motor or vacuum to keep the label roll working stably.
The importance of accurate labeling: accurate labeling, along with accurate product guidance, brings great benefits to the productivity, performance and product quality of the line. labeling line. For lines that require highly accurate labeling, the guiding, labeling and labeling parts must all be controlled accurately and consistently.
Conveyor
Description: The conveyor belt is the part that brings products that need to be labeled to the labeling area and takes the products out after labeling.
The importance of conveyor belt speed and adjustability: A conveyor belt with a stable speed and adjustable speed and size will diversify the capabilities of the conveyor belt and chain, making a chain can be fine-tuned to suit many different products
Dashboard
General introduction: the control panel includes buttons, indicator lights, display screens, etc. to show the working status of the line
Uses: The control panel needs to be able to control, monitor and fine-tune some parameters of some elements in the line to suit many working modes of each different product type.
Conclude
The wrap labeling machine is an automatic labeling machine used to wrap labels around products.
Automatic wrap labeling machines often include labeling and labeling parts as well as a conveyor belt and control panel to be able to control, monitor and fine-tune a number of parameters of the line to suit each product. Labeled.
Choosing a roll labeling machine that suits the labeling and product requirements will help the line operate efficiently, with high productivity and with few errors.
