Paper bag manufacturers require to reduce the waste of raw materials as much as possible, so the paper bag machine needs to complete stable color label correction in the shortest time when producing paper bags with color labels, and minimize the number of trial paper bags (invalid paper bags), so as to improve paper utilization and reduce production costs.
Paper bag machine equipment three core technologies
1, non-stop switch bag length, improve production efficiency
The cutting process of the paper bag machine is a typical cross-cutting application, as shown in the following figure, for the unmarked base paper, by planning two moving CAM curves, in the production and processing operation, when the paper bag length changes, it starts to plan and switch the running curve of the new specification cutter, avoiding the deceleration or shutdown, thus improving the production efficiency.
2. Develop a variety of tracing methods to improve debugging efficiency
For the production of colored base paper, cutting operations need to be carried out at the color mark, that is, when the color mark reaches right below the cutter, the cutter should also reach the cutting point. In order to achieve this requirement, when the high-speed probe sensor detects the color mark, the control system needs to perform operations and control the cutter shaft to adjust the corresponding phase. In order to meet the operating habits of different users and reduce material waste, paper bag machine solution providers need to develop a variety of tracing algorithms to improve the debugging efficiency of different base papers.
3, iterative upgrade, improve flexibility
With the upgrading of consumption and the improvement of public aesthetics, the machinery and process of paper bag machine equipment also need to be iteratively upgraded, for the need to increase the flexible needs of printing units, automatic version and automatic loading and unloading, paper bag machine solution providers need to provide a wealth of hardware and software products to meet the diversified and flexible needs of users
