Embodiment 1
[0042] see figure 1 , the flow chart of the finished paper adhesion test method provided in this embodiment. The application provides a method for testing the adhesion of finished paper, comprising the following steps:
[0043] Step 100, performing pretreatment on the stacked N sheets of finished paper to obtain pretreated paper, where N is a positive integer.
[0044] Optionally, the pretreatment includes: keeping the finished paper under the conditions of 20-50N pressure and 55-65°C for 5-7h. For example, the finished paper is kept warm for 6 hours under the condition of 20N pressure and 60°C.
[0045] It should be noted that the surface of the stacked N sheets of finished paper is wrapped with kraft paper, and the outer surface of the kraft paper is wrapped with a stretch film.
[0046] Optionally, the finished paper is A4 paper, and N is any value in the range of 500-1000, for example, 500.
[0047] Step 200, obtaining the total mass m of the pretreated paper 0 , and ...
Embodiment 2
[0072] see figure 2 , a structural schematic diagram of the finished paper adhesion test equipment provided in this embodiment. The present application provides a finished paper sticking test equipment, which is used to implement the paper sticking test method in Example 1. The finished paper adhesion test equipment includes: a pretreatment module 1 , an adhesion test module 2 , and a calculation module 3 , and the adhesion test module 2 includes a vacuum adsorption unit 201 , a detection unit 202 , and a calculation unit 203 .
[0073] The pretreatment module 1 is used for heating the finished paper.
[0074] Adhesion test module 2, used to obtain the total mass m of the pretreated paper 0 , and repeatedly execute steps S1-S3 until the quality of the remaining pretreated paper is zero.
[0075] The vacuum adsorption unit 201 is configured to perform step S1, absorbing the uppermost layer of the pretreated paper by vacuum adsorption, and transferring the adsorbed paper.

Abstract
The invention relates to the technical field of paper testing, in particular to a finished product paper adhering testing method and equipment. The method comprises the following steps of pretreatingstacked N pieces of finished product paper to obtain pretreated paper; obtaining the total mass m0 of the pretreated paper and repeatedly executing steps S1-S3 until the mass of the remaining pretreated paper is zero; S1, sucking the paper at the uppermost layer of the pretreated paper in a vacuum sucking mode and transferring the sucked paper; S2, detecting the mass mi of the remaining pretreatedpaper at the current moment; S3, according to m1 and m(i-1), calculating the weight deltami of the sucked paper in the i time; according to the total quantity N of the finished product paper, the total mass m0 of the pretreated paper, the maximum sucking frequency n and the weight deltami of the paper sucked in the i time, calculating adhering parameters of the finished product paper. By means of the finished product paper adhering testing method and equipment, the adhering parameters of the finished product paper can be accurately calculated, errors are small, and the time is saved.
Description
technical field [0001] The present application relates to the technical field of paper testing, in particular to a method and equipment for testing adhesion of finished paper. Background technique [0002] With the development of society, the application range of paper is becoming more and more extensive. For example, printing paper, industrial paper, packaging paper, etc., usually paper will be produced in large quantities. If a large number of papers are stacked together for a long time, moldy, Moisture and sticking will cause great inconvenience to the subsequent use of paper. Therefore, it is necessary to test the sticking of finished paper. [0003] At present, the existing test method for the adhesion of finished paper is to stack the papers in the warehouse, after a period of time, take out the papers, pick up the whole stack of test papers with both hands, and some parts or the whole are stuck together, and it is impossible to test one by one. If it falls freely, it...
