Introduce
A wrap packaging machine is defined as a device used to tightly wrap one or more stacked packages, through the use of layers of film or plastic, to form a protective layer against environmental impact. field during transportation.
Wrap packaging machines play an important role in the production process, providing speed and efficiency. Tight packaging helps protect products from the elements, especially important in industries such as food and pharmaceuticals. The machine’s flexibility and automation help optimize production efficiency, minimize waste and at the same time ensure packaging quality.
The article focuses on the purpose of understanding and evaluating the importance of wrap packaging machines, and explores the diverse applications of this technology in the product packaging process.
Types of wrapping machines
Handheld wrap packaging machine
Definition and purpose: Handheld wrap packaging machine is a manual packaging machine, including 1 roll of wrapping material and 1 head to hold the wrapping material.
Uses and advantages:
- Uses: used to reduce effort and easily wrap packages and products manually.
- Advantages: compact, lightweight, low price, easy to use.
Some applications: The machine is used to assist in wrapping and wrapping small, light packages that can be hand-held for wrapping.
Semi-automatic wrapping machine
Definition and purpose: A semi-automatic wrapping machine is a wrapping machine that when placing the item to be packaged on the machine, can activate the machine to start the wrapping cycle.
Uses and advantages:
- Uses: used to wrap large parcels, products or packages that cannot be held by hand.
- Advantages: the machine can wrap large packages, wrap packages semi-automatically, and has a low price.
Some applications: Semi-automatic wrapping machines are used to package large parcels or parcels that cannot be held by hand in a semi-automatic manner for storage or transportation, etc.
Automatic wrapping machine
Definition and purpose: Automatic wrapping machine is an automatic machine used to wrap and wrap materials around packages and products for storage or transportation.
Uses and advantages:
- Uses: The automatic wrapping machine can automatically wrap packages and products on the conveyor belt in a certain and cyclical cycle.
- Advantages: can package a variety of sizes and weights, productivity and packaging efficiency are higher than manual or semi-automatic packaging, saving packaging materials.
Some applications: Automatic wrapping machines are used to package packages and products in large production lines. require packages to be wrapped with high efficiency and productivity, speed while reducing the cost of wrapping materials.
Details in the wrapping machine
Film reception unit
Definition and purpose: The film receiving part is the part that holds the wrapping film roll and pulls a small part out to ready to wrap on the material.
Types of film contact parts: Film feeding units are classified according to the film roll used, including pre-stretch film, high-strength stretch film, polypropylene film, etc.
Advantages and disadvantages of each film contact:
Most of the materials used to make films have good stretch properties and good resistance to the external environment. In addition, there are some very durable films used to transport products with many edges such as LDPE plastic, however they will cost more than more commonly used materials such as polypropylene.
Turning tables
Definition and purpose: The turntable is the part to place the product or package on, then the table will rotate manually, automatically or semi-automatically to roll the package.
Types of turntables: Manual turntables use hands or mechanical mechanisms to rotate, semi-automatic turntables and automatic turntables are controlled by electricity and controllers.
Uses and advantages: The turntable helps the operator rotate the package around the film feeding unit gently and effectively. Usually turntables are designed to be able to withstand large loads depending on the volume of the package, and with the price of turntables increasing, the level of reliability and accuracy of the table also increases.
Dashboard
Definition and purpose: The control panel is a device attached to a semi-automatic packaging machine or automatic packaging line, used to control and control, as well as fine-tune parameters during the machine’s operation.
Some control panel settings: number of revolutions, package steps, rotation speed, rotation time,…
TThe importance of designing a user-friendly dashboard: When the control panel is easy to understand and user-friendly, the machine or line operator will reduce the time needed to fine-tune, control or control the machine operation, thereby increasing the productivity and efficiency of the line. pass.
Conveyor
Definition and purpose: Conveyor belt is a cluster of equipment used to bring products to the place where they need to be packaged and out of the packaging machine as well as off the line.
Different types of conveyors: roller conveyors, conveyor belts, chain belts, etc.
Advantages and applications of various types of conveyor belts:
Roller conveyor: Used for large loads, low friction, large contact surface. Roller conveyors have the outstanding feature of being able to change the horizontal size of each segment in the chain or redirect the chain to suit production purposes.
Conveyor: is a conveyor belt whose surface material is rubber, plastic,… with great friction. Conveyor belts are used to transport products on the chain in a linear manner using friction. The conveyor belt does not have the ability to change direction.
Loading chain: is a conveyor belt that uses chains, often with fixtures to hold products in a certain direction on the chain.
Conclude
In the packaging field, there are three main types of wrapping packaging machines, including manual wrapping machines, semi-automatic wrapping machines and automatic wrapping machines. Each of these machines plays an important role in optimizing the packaging process and protecting products before being shipped.
Wrap packaging machines usually include two main components: the turntable and the film feeding unit. The turntable has the function of rotating the package to create tightness and safety. The film feeding unit is where the film is supplied and wrapped tightly around the product. To achieve the best packaging performance and material savings, both of these components need to be adjusted to suit the size and characteristics of the product.
The package wrapping process and wrapping machines play an undeniable role in the final stages of the production line. This not only ensures that the product is stored safely and tightly, but also helps minimize risks and losses during transportation. In this way, wrap packaging machines not only enhance production efficiency but also contribute to final product quality and customer satisfaction.
