The structure, performance and common problems of paper machines such as toilet paper machines are as follows:
1. structure
The wire section of the paper machine is mainly composed of various guide rollers, dewatering elements, nets, racks and various other necessary structures. The guide roller includes breast roller, vacuum roller, net driving roller, correction roller, tension roller and net guide roller. Dehydration components are mainly forming plate, suction tank, water leg suction tank, vacuum suction tank and so on. In addition, a scraper cleans the surface of the guide roller with the help of a water spray pipe, which is collected by a white water tray and sent away. The trimming device uses high-pressure water to cut the wet paper sheet to a suitable width. The tension of the net is adjusted by the tensioner, and the deviation range of the net is controlled by the corrector.
2. performance
The main task of the network department is to dewater and form paper sheets. The uniform dispersion of the slurry before surfing the web is very important to obtain a uniform page with uniform banner weight, thickness, uniformity, etc. Before the paper is sent to the net through the net front box, the primary task of the net front box is to disperse the fibers evenly and spray the paper evenly onto the net. After the formation of wet paper sheet should have a certain strength, in order to smoothly lead to the press section of the paper machine. The dehydration of the net is characterized by large and concentrated dehydration, accounting for more than 90% of the dehydration of the paper machine.
3. FAQ
The net runs: the position of the guide roller has been adjusted to the end during the operation of the copper net, but the copper net still moves to one side. This may be due to the wrong position of the roller, the uneven position of a net roller during the return operation of the copper net, the uneven pressure of the roller, the wrong position of the case roller, etc.
Paste net: paste net is also a common problem in production. In production, cleaning methods can be determined for copper net and polyester net, as well as the nature of paste net dirt. Cleaning can be used pressure water flushing, steam cleaning, acid and alkali washing and organic solvent washing.
The above information is for reference only. If you need to know more about the structure, performance and common problems of the network department of paper machines such as toilet paper machines, it is recommended to consult professionals in relevant fields or consult relevant books and materials.
