hydraulic screen changer for film blowing

Plastic Blown Film Hydraulic Extrusion Screen Changer is a specialized equipment used in plastic blown film production line. The following is a detailed analysis of it:

I. Definition and function

Plastic Blown Film Hydraulic Screen Changer is a kind of equipment to realize screen changing operation through hydraulic drive, mainly used in plastic blown film production process to replace the blocked or worn filter screen, so as to ensure the continuity and stability of the production line.

II.structure and characteristics

Structure:

Hydraulic screen changer usually consists of hydraulic cylinder, filter screen, filter plate, three-way gland and other components.

The hydraulic cylinder provides driving force to push the filter mesh to move inside the filter plate to realize the mesh changing operation.

Features:

High degree of automation: through hydraulic drive, it realizes fast and accurate screen changing operation and reduces manual intervention.

High efficiency of screen changing: it can complete screen changing in a short time to ensure the continuous operation of the production line.

Good filtration effect: adopting high quality filter mesh, effectively filtering impurities in the plastic melt and improving product quality.

III.Working Principle

In the process of plastic blown film production, when the filter mesh is blocked or worn to a certain extent, the hydraulic screen changer starts to work. The hydraulic cylinder pushes the filter mesh to move in the filter plate, replacing the clogged or worn filter mesh with a new one. At the same time, the hydraulic screen changer also has an automatic cleaning function, which can clean the filter mesh and filter plate during the process of screen changing to ensure the filtering effect.

IV.Application Scene

Plastic blown film hydraulic screen changer is widely used in various plastic blown film production lines, such as LDPE (low-density polyethylene), HDPE (high-density polyethylene) and other plastic raw materials blown film production. In these production lines, the hydraulic screen changer can ensure the continuity and stability of the production line, improve product quality and production efficiency.

V.Maintenance

In order to ensure the normal operation and prolong the service life of the plastic blown film hydraulic screen changer, regular maintenance and repair is required. Specifically include:

Regularly check the sealing performance of the hydraulic cylinder and the quality of hydraulic oil to ensure the stability of the hydraulic system.

Regularly clean the filter and filter plate to prevent clogging and wear.

Regularly check the connection of each component and the degree of fastening to ensure the overall stability of the equipment.

In summary, the plastic blown film hydraulic screen changer is one of the important equipments in the plastic blown film production line, which has the features of high automation, high screen changing efficiency and good filtration effect. In order to ensure its normal operation and extend its service life, regular maintenance and repair is required.
