Description

Technical Field

[0002] In the process of making cigarette boxes, especially cigarette boxes, it is often encountered that the cigarette box paper is bounced off at the adhesive part of the cigarette box paper due to excessive indentation force, or deformed and cannot form a regular cigarette box due to too small indentation force. It is also possible that the adhesive part is partially cracked to form creases after the cigarettes are loaded. The problem of poor indentation of cigarette boxes causes unnecessary waste of manpower and working hours. Therefore, the consistency of indentation of cigarette boxes is very important, and the indentation stiffness of cigarette box paper directly determines the forming performance and packaging effect of cigarette boxes, so the stiffness of cigarette box paper is very important technically. The existing stiffness detection equipment is mainly designed according to the "Determination of bending stiffness of paper and paperboard, general principles of two-point method, three-point method and four-point method". The existing crease stiffness detection device has the problems of high test environment requirements, inconvenient control of paper bending angle, and long time-consuming sample measurement.

[0004] The above Chinese patent rotates the turntable, and during the advancement of the threaded rod, the push rod is pushed to rotate, and the rotating shaft rotates together, and the second clamping plate interlaced on the rotating shaft rotates accordingly, and the cardboard placed on the first clamping plate and the second clamping plate is bent at a certain angle, and the magnitude of the torque is read on the torque meter, and finally the stiffness value of the cardboard is calculated. Although the above technical solution is convenient for controlling the rotation angle and saving test time during implementation, the bending length cannot be adjusted, and only the stiffness value under a single bending length can be measured, which affects the stability and accuracy of the test.
