This article will comprehensively analyze the technical characteristics, working principles, and application advantages of modern paper bag production machines.
Technical features of paper bag production machines
Modern fully automatic paper bag machines integrate a variety of advanced technologies and embody the characteristics of high automation and intelligence.
Intelligent control systems are the core of modern paper bag production machines. Most high-end equipment uses a PLC programmable servo control system and a touch screen human-machine interface, allowing operators to set the bag length and other parameters within a certain range.
Automation features include: precise color mark tracking system (automatic alarm and shutdown in case of color mark error), dual photoelectric sensor limit automatic correction control system, automatic lubrication and oil supply system, etc. These features not only ensure product quality but also reduce the need for manual intervention.
In terms of adaptability , these machines typically have a wide range of specifications, capable of producing a variety of paper bags, from small food bags to large shopping bags. The equipment can also adapt to different paper materials, such as kraft paper, coated paper, offset paper, laminated paper, aluminum foil paper, waxed paper, etc.
Energy saving and environmental protection are also important features of modern paper bag production machines. They use advanced energy-saving technology to reduce energy consumption and waste generation, in line with the requirements of modern society for environmentally friendly production.
Main types of paper bag production machines
According to product structure and functional requirements, there are many types of paper bag production machines to meet different production needs.
Square bottom paper bag machines are commonly used in the production of shopping paper bags. They are capable of producing paper bags with a square bottom. This type of equipment usually has a wide production range and can handle square bottom paper bags of different sizes and specifications.
The three-dimensional paper bag making machine can produce paper bags with three-dimensional cavities. Through a special three-dimensional edge forming mechanism, the folded paper is squeezed to form a three-dimensional cavity, which is suitable for packaging needs that require more internal space.
The multifunctional fully automatic paper bag machine is the mainstream product in the current market. It integrates multiple functions and can produce various environmentally friendly paper bags such as shopping bags, snack food bags, bread bags, vomit bags, dried fruit bags, etc.
Different models of machines also differ in production speed and product specifications. Users can choose appropriate equipment according to their production needs.
Working principle of paper bag production machine
Although there are many types of paper bag production machines, their basic working principles are similar and include the following key steps:
Unwinding and deflection correction : The paper roll is installed on a pneumatic or hydraulic lifting structure, and the fully automatic constant tension control system and deflection correction system ensure smooth paper transportation.
Gluing and Tubing : After the paper passes through the edge gluing device, it is folded into a tube. This step usually uses an adjustable tube template with a synchronous adjustment structure, which saves template costs and is simple and quick to adjust.
Cutting and creasing : After the paper roll is formed, it is cut into the specified length and the bottom is creasing simultaneously. Modern equipment often uses a non-stop creasing position adjustment structure, making the creasing position adjustment more convenient.
Bottom Forming and Delivery : The final stage involves bottom folding, gluing, and bottom shaping, with the finished bag then delivered via a conveyor. Some high-end machines also feature thumb closures and flat bottom cutting devices, offering a variety of bag-making options.
The entire production process is monitored by a computer central control system to ensure coordinated operation of all links and achieve efficient production.
Technical parameters of paper bag production machines
Understanding the technical parameters of paper bag production machines is crucial for selecting the right equipment and planning production. Here are some basic technical parameters of typical paper bag production machines:
| Parameter Type | Parameter range | illustrate |
