Description

  The present invention relates to a desktop cutter that can collect cutting powder generated by cutting.

2. Description of the Related Art A table-type cutting machine (a circular saw) called a slide marnoco or a tabletop marnoco has been known. This tabletop-type cutting machine includes a table on which a cutting material is placed, a main body support portion disposed on the back side of the table, and a cutting machine main body supported by the main body support portion so as to be swingable up and down. Prepare. The cutting machine body includes a circular rotary blade that rotates using an electric drive motor as a drive source. This rotary blade is provided with a cutting edge in the circumferential direction. A blade case formed so as to cover the rotary blade is disposed on the upper side of the outer periphery of the rotary blade.
This rotary blade cuts the cutting material by rotating while blowing the cutting powder (sawdust) upward from the cutting site. At this time, the blown-up cutting powder may accumulate at the cutting site of the cutting material. If cutting powder accumulates in this way, it will make it difficult to see the smear lines and cut parts drawn on the cutting material. If it does so, a work environment will be impaired or workability will be impaired. For this reason, in this type of cutting machine, various devices have been devised in order to collect or remove cutting powder in the vicinity of the cutting site that is generated in the cutting process.
That is, in the above-described tabletop-type cutting machine, the cutting powder scattered in the blade case is collected in a dust collection container such as a dust collection box using the flow of wind generated by the rotation of the rotary blade. Is known (see, for example, Patent Document 1 and Patent Document 2). In this function of collecting dust, a case-side dust collection port that opens to communicate with the dust collection container is provided on the blade case side, and the wind generated by the rotation of the rotary blade is in this case. It is to be sent to the dust collection container through the side dust collection port.
In addition, the dust collection container of this type of tabletop cutting machine is supported by being connected to the case-side dust collection port on the blade case side in a communicating state, so when the cutting machine body is swung up and down Are easily affected by the vertical swing. For example, when the cutting machine main body is located at the upper limit position, the space from the inside of the dust collecting container to the case side dust collecting port is located so as to be arranged substantially in the horizontal direction.

  By the way, the cutter body is locked by being positioned at the lower limit position when the cutter is carried after the cutting operation. In this case, the space from the inside of the dust collecting container to the case side dust collecting port is inclined downward. For this reason, when carrying this locked cutting machine etc., it is easy to drop cutting powder on a table from the case side dust collecting port by the dead weight of cutting powder. Then, the subsequent work environment may be impaired, and workability may be hindered.

  The present invention has been made in view of such circumstances, and the problem to be solved by the present invention is that a rotary cutter rotates in a tabletop cutting machine that can collect cutting powder generated by cutting processing. Even when the cutting machine main body is positioned at the lower limit position in a state in which the cutting is stopped, the cutting powder is reduced from dropping from the case-side dust collecting port onto the table due to the weight of the cutting powder.

In solving the above-described problems, the cutting machine according to the present invention employs the following means.
That is, the cutting machine according to the first aspect of the present invention is a tabletop-type cutting machine capable of collecting dust from cutting powder generated by a cutting process, and is equipped with a base and a cutting material supported by the base.

According to the cutting machine according to the first aspect of the present invention, the first conveyance path forming member and the second conveyance path forming member are when the position of the cutting machine body that swings up and down is located at any position. Moreover, the connection state of the 1st conveyance path formation member and the 2nd conveyance path formation member can be maintained. Here, when the cutting machine main body is located at the lower limit position, only the second transport path forming member among the transport path constituent members for transporting the cutting powder is inclined downward toward the case-side dust collecting port. It can be a part to do. That is, the first transport path forming member is fixedly supported with respect to the main body support portion, and can be maintained in the same position regardless of the swinging position of the cutting machine main body. As a result, even if the feed air flowing from the case side dust collection port to the dust collection container (for example, a dust collection box) is stopped by stopping the rotation of the rotary blade, the second conveyance of the entire conveyance path is stopped. Only the path forming member can be a conveyance path constituting member that is easily affected by the weight of the cut powder.
