Embodiment Construction
[0021] The structure and effect of the present invention will be described in detail by citing the following embodiments in conjunction with the accompanying drawings.
[0022] Such as figure 1 As shown, it is a band saw machine 10 using a safety protection mechanism 20 according to a preferred embodiment of the present invention. The band saw machine 10 shown in the figure mainly includes an upper pedestal 11, a lower pedestal 12, and an upper pedestal 11. A driven wheel 13, a driving wheel 14 arranged in the lower pedestal 12, a saw band 15 wound around the driving wheel 14 and the driven wheel 13, and a motor 16 arranged in the lower pedestal 12 and connected to the driving wheel 14. Please refer to figure 2 and image 3 , The safety protection mechanism 20 of the present invention has a relay 30 , a tension adjustment device 40 , and a pressing plate 60 .
[0023] The relay 30 is fixed in the upper base 11 and electrically connected to the motor 16 for controlling the ...

The invention relates to a safety protection mechanism for a band-sawing machine. The band-sawing machine comprises a driving wheel, a driven wheel, a saw band encircled the driving wheel and the driven wheel, and a motor connected with the driving wheel. The safety protection mechanism for the band-sawing machine is characterized in that the safety protection mechanism comprises a relay, a tensioning device and a pressure plate, wherein the relay used for controlling action of the motor is electrically connected with the relay; the tensioning device is provided with a lifting base; the lifting base is connected with the driven wheel and the tension of the saw band is adjusted through the driven wheel; the pressure plate is connected with the lifting base of the tensioning device and positioned above the relay, so that the pressure plate can be away from or press the relay based on the lifting or descending of the lifting base to start or shut down the relay. According to the safety protection mechanism for the band-sawing machine, as the relay can be started or shut down through the lifting or descending of the lifting base through the pressure plate, the action of the motor can be controlled by the relay and the safety of a user is protected.
Description
technical field [0001] The invention relates to a band saw machine, in particular to a safety protection mechanism for a band saw machine. Background technique [0002] Before operating the band saw machine to saw the workpiece, the operator must first adjust the tension of the saw band to an appropriate tightness to maintain the stability during sawing. Once the saw band is to be replaced, the operator must The saw band can be removed smoothly only after the saw band is loosened. [0003] However, for the operator, at present, it is only possible to judge whether the saw band is adjusted to a tight state by visual inspection or feel. Pretty serious injury. Therefore, current band saw machines do not provide good operational safety. Contents of the invention [0004] In view of the above problems, the main purpose of the present invention is to provide a safety protection mechanism for a band saw machine, which can effectively improve the operation safety. [0005] In ...
