Product Description

Durable Compound Doctor Blade Holder for Industrial Printing machine

Product Description

Pneumatic Doctor Blade is a key device in paper machinery for cleaning the surfaces of drying cylinders, press rollers and other equipment. It precisely controls the scraper pressure (linear pressure range 0.3-1.5 MPa) through a Pneumatic system to efficiently remove residual paper scraps, rubber compound and impurities, ensuring the quality of paper surface and the stability of equipment operation. Its main body is made of 304 stainless steel or tungsten carbide coated blades (with a thickness of 1-6mm), suitable for roller diameters of Φ800-6000 mm, and the working temperature can reach 180°C. The products include standard type, Air-Cushioned type (flexible contact to prevent roller surface damage) and Oscillating type (Oscillating for uniform cleaning). They support PLC intelligent control (pressure ±2% error) and modular quick-change design. With an IP65 protection level, they are suitable for high-speed paper machines (≤2000 m/min). It saves energy by 15%-20%, complies with the ISO 15361 standard, and is widely used in the production lines of cultural paper, toilet paper and packaging paper. It is compatible with mainstream equipment.

The upflow pressure screen is a highly efficient and energy-saving pulp screening equipment, widely used in the fields of waste paper pulping, pulp screening before paper machines and recycled pulp treatment. Its core advantage lies in achieving efficient impurity removal and fiber grading through a unique upflow structure and pressure difference screening principle, significantly enhancing the quality of the slurry and production efficiency.

Paper making machinery mesh cages (also known as circular mesh cages or forming mesh cages) are the core components of circular mesh paper machines, mainly used for pulp forming and dewatering. Their design directly affects the quality and output of paper. The cage is composed of a main shaft, a net frame, spokes and spacers. The spokes are evenly spaced and fitted onto the main shaft, and the net frame is installed on the spokes. According to the structure, it can be classified into common type, plate type, evacuated type, vacuum type, etc. According to the material, it can be divided into stainless steel, all-copper, etc. Among them, stainless steel mesh cages have become mainstream due to their advantages such as corrosion resistance, light weight and short maintenance cycle. Its structural stability, water filtration efficiency and corrosion resistance directly affect the quality of paper and production efficiency, and it is suitable for the production of various types of paper such as cultural paper, packaging paper and special paper.
 

The pulp pump of paper making machinery is a core equipment in the paper making industry used for transporting pulp, white water, additives and other media, directly affecting production efficiency and paper quality. Its design needs to take into account wear resistance, corrosion resistance, high efficiency and low energy consumption to adapt to the complex working conditions of high temperature, high humidity and high solid content in the paper making process.

The high-concentration descaling device is an indispensable core purification equipment in the modern paper making industry, specially designed for the impurity removal treatment of high-concentration pulp. Its core function is to effectively separate heavy impurities such as metal particles, sand and gravel, glass fragments, plastic fragments, and incompletely crushed fiber bundles from the pulp through physical centrifugal separation technology, thereby significantly improving the purity of the pulp. As a "pre-purification barrier" in the paper making process, the high-concentration descaling device is suitable for various scenarios such as waste paper recycling, wood pulp and chemical pulp treatment, and specialty paper production. It performs particularly well in the treatment of pulp with high impurity content, such as waste paper deinking pulp and OCC (old corrugated box) pulp. This equipment adopts a tangential slurry feeding method, causing the slurry to form a high-speed vortex within the cone. Heavy impurities are thrown towards the wall of the device due to centrifugal force and eventually settle in the sediment tank, while the good slurry is discharged from the central low-pressure area. This design effectively improves the purification efficiency of the pulp and reduces the loss of fibers.
