The above description is the structure of each main component of the creation embodiment and its configuration description.

The working status of the creation, the state of the replacement brush, and the maintenance status are respectively described below.

Working state: refer to Figures 2 and 5, and pull the first and second brush holders 21, 22 Close to each other, and the first column portion 712 of the first driving member 71 and the second column portion 722 of the second driving member 72 are simultaneously located in the working area 12, at this time, by the pulling force of the tension spring 80 The first and second column portions 712 and 722 are brought close to each other, and the first and second brush holders 21 and 22 are brought close to each other, and finally the first and second brush holders 43 and 44 are brought close to each other and used to clamp the saw blade 90. The saw blade is used to perform the sawing operation on the saw blade. At this time, the first and second driving members 71 and 72 respectively disposed on the first and second brush holders 21 and 22 have first and second driving portions. Neither 711 and 721 are within the sensing range of the first and second sensing elements 61 and 62, respectively, and therefore are still in an active state in this state.

Replacing the state of the brush: Referring to Figures 5 and 6, in the working state, when the first and second brushes 43, 44 are worn, the first and second brush holders are pulled by the tension of the tension spring 80. 21, 22 are close to each other such that the first and second brushes 43, 44 remain in the state of holding the saw blade 90, and when the first and second brushes 43, 44 reach the set wear level simultaneously or individually The first and second driving members 71 and 72 are respectively disposed on the first and second brush holders 21 and 22, and the first and second driving portions 711 and 721 are respectively located at the first and second sensing positions. Within the sensing range of the elements 61, 62 (Fig. 6 shows the state in which the first and second driving portions 711, 721 are simultaneously located within the sensing range of the first and second sensing elements 61, 62), therefore, The first and second sensing elements 61, 62 respectively output a signal separately or simultaneously for the band saw machine to immediately perform various warning or shutdown control actions, so that the detection design can be used to replace the individual or simultaneous First and second brushes 43, 44.

Maintenance status: Refer to Figures 6, 7, and 8 when the replacement brush status occurs. In addition to stopping the band saw machine, the repairer must pull the first and second brush holders 21, 22 relatively apart, so that the tension spring 80 accumulates an elastic restoring force, and continuously pulls the first and second brushes. The seats 21, 22, and the first and second column portions 712, 722 of the first and second driving members 71, 72 are moved from the working area 12 of the body 10 to the maintenance area 13, at this time, by the pulling The elastic restoring force of the extension spring 80 causes the first and second brush holders 21, 22 to be relatively close until the first side surface 713 of the first driving member 71 abuts against the first abutting surface 14 of the body 10, and The second side surface 723 of the second driving member 72 abuts against the second abutting surface 15 of the body 10, and the first and second brush holders 21 and 22 and the body 10 are kept in abutting state. The first and second brushes 43, 44 can be replaced at the same time or individually.

According to this, when the replacement of the brush is carried out, the design of the creation can be replaced by only one pull-out action, and the cleaning device of the present invention is mainly used for the replacement work. Through the design of the main body 10, the first and second brush holders 21 and 22, the first and second driving members 71 and 72, and the tension spring 80, not only the components are small, but also the structural design is simple, so By achieving a relatively simple structural design, the purpose of removing and cutting the saw blade and replacing the brush can be achieved, and the assembly and maintenance of the cleaning device can be simplified.

In view of the above, the above embodiments and illustrations are only preferred embodiments of the present invention, and the scope of the novel implementation cannot be limited thereto, that is, the equal changes and modifications made by the present invention in accordance with the scope of the present patent application are all Should be covered by this new patent Within the scope.
