Description

Technical Field

[0001] The application of the utility model relates to the technical field of trimming machines, specifically a waste board crushing and recycling mechanism for a particle board trimming machine. Background Technique

[0002] A trimming machine belongs to a type of cutting machine. During the working process of the trimming machine, in addition to the main target products produced, there are also the discarded board edges sawed off. These board edges need to be processed, recycled or sold. However, before processing, they need to be crushed into small pieces from the long and large board edges.

[0003] The conventionally cut half-edges mainly include two types. One is the board edge cut from a single board blank with a limited length, which can be uniformly reprocessed by the method of recycling after processing. The other is the board edge cut during the processing on the overall production line. Since the board has not been cut into individual pieces, this type of cut board edge is continuous. For the crushing and recycling mechanism of the second type of board edge, most of the methods adopted in the current prior art are to directly crush the board edge with a cutting knife or a crushing mechanism. For example, the patented technology with the application number 201821029185.9 discloses a board edge crushing device for a sawing machine, which uses a crushing mechanism rotating around a horizontally arranged shaft to crush the board. However, the generated debris will fly everywhere during the crushing process, affecting the cleanliness of the board surface. At the same time, it is easy to interfere with the end face of the conveying mechanism, and it is easy to leave debris on the end face of the conveying mechanism, which is inconvenient to clean.
