Press roll

The press roll is the main component of the press device. Both ordinary press and positive press use flat roll press. The structure of the flat roll press, the upper roll is a stone roll, and the lower roll is a rubber roll. Both rolls have flat and smooth roll surfaces. The bottom roll of the flat roll press is a rubber-coated cast iron roll.

Combination roller

After the pulp is uniformly treated in the paper making process, because the pulp contains a large amount of water, it needs to be pressed to discharge the water during the forming process of the paper product. The composite roll is a commonly used dehydration part on the paper machine, and a large amount of water is evenly arranged on the surface. Hole, in the process of paper processing and production, it is necessary to use a composite roller to remove the moisture in the pulp.

Imitation stone roller

It is mixed with special grade synthetic rubber material and nano-grade filling material. It has good paper peeling performance and unconventional wear resistance. It can be used with a scraper and can meet the harsh application environment of high line pressure. The imitation stone rubber roller has low quality, high hardness, good paper making and release performance, impact resistance, abrasion resistance, acid and alkali corrosion resistance and high production efficiency. It is an ideal substitute for natural stone roller and has good social and economic benefits. Structure Principle The imitation stone rubber roller is composed of a metal roller core and a rubber coating (including a surface adhesive layer and an adhesive layer). In order to satisfy the imitation stone rubber roller with high hardness, good paper making and release properties, pressure resistance, abrasion resistance, and aging resistance , Heat resistance, acid and alkali corrosion resistance and other performance requirements, the surface glue adopts NR/BR/high styrene resin and the system as the main material, adopts glass hollow beads/zinc oxide/superfine aluminum silicate/white carbon black/methyl Magnesium acrylate system is used as reinforcement system.

Blind press roll

A large number of holes with a certain depth are drilled on the surface of the pressure roller. The depth of the holes is best to use two or three different sizes of depths and the same arrangement. The bottom of the holes is not connected to the atmosphere or vacuum, so it is called a blind hole.

Bow curved roll

The curved roller is a series of rotatable curved roller surfaces installed on the curved shaft to reach the roll that stretches the web, which can eliminate the wrinkles in the web traveling process and prevent the possible staggering during the material cutting process.

Soft calender roll

Its function is to make the paper web density uniform and soft and smooth. It can be lightly pressed on a calender and make the surface of the paper web smoother. Due to the elastic encapsulation, they have excellent heat resistance and scratch resistance. Soft calender rolls are mainly used on soft calenders.

Guide roll

Paper machine guide rolls are divided into two types: felt rolls and screen guide rolls. The application parts include pressing, drying, crimping, rewinding and other parts. Felt ducts, wire guide rolls, paper guide rolls, chrome-plated rolls, etc. are all over the front and back of the paper machine. Guide rolls guide and drive the wire and felt in the wet end and drying section of the paper machine. The guide rollers in both areas use the same bearings. However, different lubrication and sealing are used depending on the application location. In the old paper machine, the wet end section is usually lubricated with grease, and the dry section is lubricated with oil. In modern paper machines, both sections are lubricated with oil circulation. Due to different working conditions, the wet end and dry section need to be lubricated with their own oil circulation.
