Description

A dynamic positioning system and positioning method

technical field

The invention relates to the technical field of paper towel embossing machines, in particular to a dynamic positioning system and a positioning method.

Background technique

At present, the main types of paper towels and toilet paper are: roll paper, boxed paper towels, flexible packaging removable paper towels, paper handkerchiefs, small trays of paper, toilet paper, kitchen paper, etc. The number of layers of paper towels is two or two More than one layer; in order to enhance the smoothness of the paper surface, the paper product is usually calendered, and the paper fibers are reoriented and rebonded on the surface of the paper web. In order to achieve a better appearance and decorative effect, the surface of many paper towels will also be pressed There are embossing patterns, and there are various embossing patterns. These patterns are all realized by paper towel embossing machines. The existing paper towel embossing machines generally include upper and lower embossing rollers. Carry out rolling to make the paper towel surface produce lines, but because the surface temperature of the roller is basically at room temperature, in order to make the embossed paper towels have clear and perfect lines, it is often easy to crush the fibers during the embossing process, making the paper The strength and toughness deteriorate, and it is easy to be torn. Consumers have no sense of security during use, and the surface of embossed paper towels generally has a concave-convex pattern, which is rough and loses the softness and softness that the product should have. smoothness.

At present, point-to-point embossing, due to the speed difference of the pressure roller, there will be misalignment between the two layers of paper during the embossing process. After the operator finds the misalignment, it needs to stop and adjust, which will affect the work efficiency and cause waste of raw materials.

The third step, at this time, the second dynamic sensor synchronously tracks the cross line of the second roller body, and compares the position data with the first dynamic sensor in real time, and dynamically adjusts the rotation position of the roller body according to the position difference, so as to achieve the same as the first roller body. The positional relationship of the roller body can realize the dynamic adjustment of the embossed paper with inaccurate positioning during the embossing process.

Compared with the prior art, the beneficial effects of the present invention are as follows:

1. The present invention adopts point-to-point embossing. During the embossing process, the first dynamic sensor tracks the cross line of the first roller body for real-time data transmission, while the second dynamic sensor tracks the cross line of the second roll body and communicates with the first dynamic sensor. The sensor compares the position data in real time, and dynamically adjusts the rotation position of the roller body according to the position difference to achieve the positional relationship with the first roller body, and can dynamically adjust the embossed paper with inaccurate positioning during the embossing process.
