Introduction
In modern industrial production, carton packaging machines are widely used in the packaging process of various commodities. One of the core components of the carton packaging machine is the bottom-sealing device. The bottom sealing device undertakes the important task of sealing the bottom of the carton to ensure the integrity and stability of the package. Then, this article will briefly introduce the relevant content of the bottom sealing device in the carton packaging machine.
1. What is the bottom sealing device?
The bottom sealing device is a key component in the carton packaging machine which is used to seal the bottom of the carton. The sealing and stability of the carton can be ensured by sticking tape, hot melt adhesive, and other packaging materials on the bottom of the carton. The main purpose of the back cover device is to prevent the carton from cracking, loosening, or damaging during transportation and storage.
2. Features of the bottom sealing device
- Fast and efficient:
Due to the mechanized operation, the efficiency of the back sealing device is very high, and it can handle the back sealing of a large number of cartons to meet the needs of mass production. It quickly and accurately applies packaging material to the bottom of the carton, increasing packaging speed and efficiency.
- Stable and reliable:
The bottom sealing device needs to provide a strong and reliable sealing effect to ensure the integrity and stability of the bottom of the carton; it can resist external pressure and vibration and ensure the safety of the product during transportation and storage, especially in the transportation of heavy objects and The storage process can well protect the contents of the carton.
- Versatile:
Different carton sizes and packaging needs may require different types of back closures. Therefore, back-sealing devices should be adaptable to handle cartons of different shapes, sizes, and materials.
- High uniformity:
As it is a piece of automated equipment, the accuracy of all back sealing devices is particularly high, the positions of the tapes of all packaged cartons are very uniform and precise, and the appearance of the packaged cartons is very uniform.
3. Types of the bottom sealing device
Depending on the carton packaging machine and the number of layers of cartons, there are different classifications of back cover devices. In general, there are two main different types of back cover devices:
- Veneer bottom sealing device:
The single-panel bottom sealing unit is suitable for cartons that require separate handling of the top and bottom covers. The device forms a tooth-shaped seam in the back cover area through complex movements and manipulations so that the bottom cardboard is perfectly sealed together.
- Root card bottom sealing device:
The root card back cover device fixes the carton through the mechanical arm and the port and tightly connects the bottom of the carton together through the precise merchant flap back cover design.
4. The working principle of the bottom sealing device
The working principle of the bottom sealing device mainly depends on its type and design. Taking the tape back cover device as an example, it usually consists of a tape supply system, a tape cutting mechanism, and a tape pressing mechanism. The tape supply system supplies the tape and delivers it to the cutting mechanism. The cutting mechanism cuts the tape to an appropriate length according to the size and requirements of the carton. The tape lamination mechanism applies the cut tape to the bottom of the carton to form a secure closure.
5. Working steps of the bottom sealing device
Different types of bottom sealing devices work differently.
- The working principle of the veneer back-sealing device is generally divided into the following steps:
1). Putting in the carton: Put the carton to be back-covered on the working table of the back-sealing device.
2). Manual adjustment: According to the size and shape of the box, manually adjust the position of the clamp of the back cover device.
3). Adhesive glue: Apply glue or hot melt glue to the bottom of the carton.
4). Mechanical sealing: Activate the mechanical structure of the bottom sealing device, and seal the bottom of the carton according to the predetermined method to form a firm bottom cover.
- The working principle of the root card back sealing device is also similar; the main steps include:
1). Putting in the carton: Put the carton to be back-covered on the working table of the back-sealing device.
2). Automatic adjustment: According to the size and shape of the box, the back cover device will automatically adjust the position of the clamp.
3). Adhesive glue: Apply glue or hot melt glue to the bottom of the carton.
4). Mechanical binding: The root card bottom sealing device will automatically fix the bottom of the carton through the mechanical arm and the port.
5). Merchant flap: Through the design of the merchant flap, the bottom of the carton is accurately sealed.
Conclusion
The bottom sealing device in a carton packer is a critical component to ensure the integrity and stability of the package. It has the characteristics of being fast, efficient, stable and reliable, flexible and accurate, and different types of devices can be selected according to different carton sizes and packaging requirements. The working principle and working method of the bottom sealing device vary according to the type and design, but all aim to ensure the sealing quality and stability of the bottom of the carton. Through the excellent bottom sealing device, the carton packaging machine can realize the automatic, high output, and high-quality sealing process, so as to improve the packaging efficiency, reduce the loss rate, and ensure the safety of the product during transportation and storage.
