A protective medium density fiberboard thermal mill and its working method

Abstract

The invention discloses a protective medium-density fiberboard thermal grinder, which comprises: a thermal grinder shell, a cover plate, a movable grinding disc, a movable grinding disc grinding disc, a fixed grinding disc, a fixed grinding disc grinding disc, a grinding disc protection mechanism and a casing protective cover, There is a moving grinding disc inside the heat mill housing, and a moving grinding disc grinding plate is arranged on the moving grinding disc; a cover plate is arranged on one side of the heat grinding machine shell, a fixed grinding disc is arranged inside the cover plate, and a fixed grinding disc grinding plate is arranged on the fixed grinding disc; The grinding plate and the fixed grinding plate are provided with a grinding plate protection mechanism; the outer shell of the thermal grinding machine is provided with a shell protective cover; it also includes a sealing mechanism; it also includes a working method of a protective medium density fiberboard thermal grinding machine; Cut off the structure, deal with the large fiber clusters and foreign matter entering the thermal grinder, reduce the damage of the grinding disc, and increase the service life of the grinding disc. On the other hand, the outer layer of the thermal grinder is improved, which can buffer and deflect the external force, ensuring The integrity of the main part of the thermal grinding machine also avoids the exposure and collapse of the grinding disc, which has high safety.

Description

technical field [0001] The invention belongs to the field of fiber processing equipment and technology, in particular to a protective medium density fiberboard heat refiner and its working method. Background technique [0002] As a continuous separation equipment for separating raw materials such as wood chips into fibers, the heat mill is one of the key equipment in the medium and high density fiberboard production line. With the rapid development of my country's medium and high density fiberboard industry in recent years, the heat mill has also gained Rapid development. As an important production equipment for MDF, the working quality of the heat refiner usually determines the quality of the finished board. [0003] Yet present thermal grinder still has many weak points. For example, most of the current thermal grinding machines have the problem of short service life and easy damage of the grinding discs. Due to the high cost of the grinding discs and the fact that they a...

AI Technical Summary

Problems solved by technology

[0005] 1. Most of the current thermal grinding machines have the problem of short service life and easy damage of the grinding discs. Due to the high cost of the grinding discs and the fact that they are easily damaged when encountering hard objects, the service life of the grinding discs is short and the practicability is poor.

[0006] 2. Most of the current thermal grinding machines have the problem of debris slipping when the grinding plate is damaged, causing secondary damage. At the same time, it is easy to miss the debris when replacing the grinding plate, which affects the quality of the finished product and easily damages the new grinding plate.

[0007] 3. Most of the current thermal grinding machines are vulnerable to impact damage. They are easily damaged when encountering a large impact, and the safety is poor.
