Description

Technical Field

[0001] The utility model relates to the field of wood processing equipment, in particular to a double-end tenoning machine for wood. Background Technique

[0002] For the existing double-end tenoning machine for wood, the following methods are generally used to load the wood to be processed: One is manual loading, which is the most traditional method. That is to say, the wood to be processed is placed on the processing station by manual, and then after being pressed and fixed by a pneumatic pressing block, the wood to be processed is processed. This loading method has certain safety hazards. If not careful, one will be injured by the pneumatic pressing block. The other is belt loading. The wood to be processed is placed on the belt by manual, and then the belt transports the wood to be processed to the processing station. Although this loading method eliminates the safety hazards, the position accuracy of loading is insufficient and it cannot be accurately transported to the processing station, which will affect the subsequent processing.

[0003] In addition, for the existing double-end tenoning machine for wood, the tool assembly is arranged on one side of the wood processing position. When the other end of the wood needs to be processed after one end of the wood is processed, the wood needs to be flipped, so the processing efficiency is not high. Content of the Utility Model
