Embodiment Construction

[0021] Such as figure 1 and figure 2 As shown, the method for monitoring the thickness of roll paper provided by the present invention includes the following steps.

[0022] Firstly, a first time point t1 is selected, and the total length L1 of the roll paper and the diameter D1 of the roll paper at the time t1 are measured at the first time point t1.

[0023] In this embodiment, the paper 100 is wound around the paper core tube 10, wherein the diameter of the paper core tube 10 is d, and the transmission speed of the paper 100 is v. In general, the paper 100 They all perform winding operations at a constant speed.

[0024] In the present invention, the selection of the first time point t1 can be set according to different monitoring requirements, and it can be the moment when the roll paper just starts to be rolled, or it can be a certain time point during the paper roll-up process.

[0025] At the first time point t1, the total length L1 of the roll paper=vt1, where v is...

Abstract

The invention relates to a monitoring method and a monitoring system of roll interior thickness of roll paper. The monitoring method comprises the following steps of: selecting a first point t1 in a paper rolling procedure, measuring the total length L1 of the paper rolled till t1 and the diameter D1 of the formed roll paper at t1; selecting a second point t2 after the first point t1, and measuring total length L2 of the paper rolled till t2 and the diameter D2 of the formed roll paper at t2; and measuring the roll interior thickness of the roll paper in t1-t2 time interval by utilizing the obtained total lengths L1 and L2 of the rolled paper as well as the diameters D1 and D2 of the roll paper at the first point t1 and the second point t2 according to the formula that the roll interior thickness=[pi(D1<2>-D2<2>) / 4](L1-L2). The invention also relates to a monitoring system of the roll interior thickness of the roll paper.

Description

technical field [0001] The invention relates to a monitoring method and a monitoring system for the inner thickness of roll paper. Background technique [0002] The production process of paper is well known to those skilled in the art. After the prepared pulp is formed, squeezed, dried, and creped, it is wound up to obtain a base paper roll. The base paper roll is based on the configuration parameters of production and processing equipment and The customer's demand and other requirements go through the rewinding section or not, and then go through the processing process to obtain the final product. No matter what paper product, thickness is one of the most important manifestations of its quality, and maintaining the uniformity of thickness has become a very important control index in the paper production process. In the actual production process, the paper thickness of the base paper under pressure in the paper roll is generally called "in-roll thickness" or "in-wound calip...
