Problems solved by technology

At present, when inspecting the quality of the forming fabric, the tension control of the forming fabric is not carried out. Since the forming fabric that has not been shaped has a certain degree of shrinkage, some subtle quality problems cannot be found, and the inspection effect is not good, so it cannot be provided. high quality forming fabric

Embodiment 1

[0012] see figure 1 , a method for inspecting a papermaking forming wire is provided in the present embodiment, comprising the following steps:

[0013] a. Place the forming net 2 to be inspected on the position of the coiled net steel pipe 1, and send the forming net 2 from top to bottom;

[0014] b. The lower coil steel pipe 3 coils the delivered forming net 2 while the upper coil steel tube 1 delivers the forming net 2;

[0015] c. Check the forming net 2 that is sent down with the coiled net steel pipe 1, and use the torque to control the coiled net motor 4 at the same time.

[0016] Among them, the speed at which the upper coil steel pipe 1 feeds the forming net 2 is lower than the speed at which the lower coil steel tube 3 coils the forming net 2, so that the forming net 2 can always maintain a certain tension during the inspection process, and it is easier to find small quality problems. Put the lower rolled mesh steel pipe 3 on the rolling mesh equipment 5, and the ...

Abstract

A method for checking paper-making forming fabrics includes following steps: a, placing a forming fabric to be checked on an upper fabric rolling steel pipe and feeding the forming fabric from top to bottom; b, rolling the forming fabric fed by the upper fabric rolling steel pipe by a lower fabric rolling steel pipe; and c, checking the forming fabric fed downwards along the upper fabric rolling steel pipe while using moment to control a fabric rolling motor. During checking of the forming fabric, tension of the forming fabric is reasonably controlled, so that subtle quality problems of the forming fabric can be found more easily to provide high-quality forming fabrics. In addition, tension control is realized through a moment control motor, different from a speed control motor, the moment control motor can constantly maintain uniform moment on the forming fabric and cannot pull the forming fabric, speed is low when resistance applied to the motor is large, speed is high when resistance applied to the motor is small, and the moment is fixed, so that the service life of the rolling motor is effectively guaranteed.

Description

technical field [0001] The invention relates to an inspection method, in particular to a method for inspecting a paper-making forming wire. Background technique [0002] The high speed of paper machines, the complexity of slurry composition, and the continuous improvement of people's requirements for paper quality have made paper workers put forward higher and higher requirements for paper machine fabrics. The forming wire in the paper machine fabric plays the role of dehydrating the pulp and forming the paper sheet. In addition to having excellent fiber support, high dewatering performance and ensuring a good filter surface for paper sheets, the forming wire also needs to have high running stability. Optimizing the selection of a forming fabric with a mature manufacturing process can achieve the goals of reducing non-production time, improving paper quality, and reducing production costs. Therefore, in order to avoid some problems in the process of producing paper-making ...
