Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the invention can be more easily understood by those skilled in the art, thereby making the scope of the invention more clearly defined.

Example 1

Referring to the attached drawings 1-2, a protection device for a feeding mechanism of a wood working machine is provided, wherein a sensor 6 is arranged at one end of a feeding platform 2 of the wood working machine 1; the sensor 6 is fixed on the feeding platform 2 through a sensor bracket 7; the sensor 6 is a laser sensor; a reflector 8 is arranged at the position opposite to the sensor 6 at the other end of the feeding platform 2; the feeding platform 2 is also provided with a plurality of log supports 5; the log support 5 is provided with a through hole 501; the light of the sensor 6 can pass through the through hole 501; the sensor 6 is electrically connected with a controller of the woodworking machine 1; when the sensor 6 cannot receive the light reflected by the reflector 8 for a certain length of time, the controller controls the woodworking machine 1 to stop running, otherwise, the sensor 6 can influence the running of the woodworking machine 1.

The number of the sensors 6 is at least 2; the setting of a plurality of sensors 6 leads the protection rate to be greatly improved.

The distance between the log supports 5 is less than half of the length of the logs 4.
