Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a suction type cutting machine that suctions a soft and flexible object such as cloth into a main body and cuts the suction part using a rotary blade provided inside the main body. .

Scissors are a very common method for cutting cloth, etc., but doing this work for a long time causes a lot of fatigue, and the monotonous work is painful, especially when cutting curved shapes. There are problems such as the need for skill to operate the scissors when using the scissors.

Furthermore, when using a cutter such as a knife, a considerable amount of pressing force is required, which causes severe fatigue, is dangerous, and is difficult to work with, and it is also necessary to place a cutting board under the fabric. , and other cutting means such as laser beams, water jets, air jets, etc., are too uncommon, the equipment itself is expensive, and is for special applications.

The present invention was developed in view of the above circumstances, and it solves the conventional problems through simple and rational operation, and cuts fabric etc. by simply moving the main body along the cutting line of the object to be cut. It is an object of the present invention to provide a suction type cutting machine that can safely and quickly perform cutting operations with little physical fatigue during long hours of operation.

Embodiments of the present invention will be described in detail with reference to the drawings.
2 to 4 show a first embodiment of the present invention, in which 1 is a hollow pipe connected to a vacuum cleaner (suction device) 3 in a general household through a flexible pipe 2, as shown in FIG. The main body 1 has an elongated opening 4 formed in its tip wall. A shaft 5 perpendicular to the longitudinal axis of the opening 4 is horizontally mounted on the inner lower part of the main body 1, and the shaft 5 is aligned with the longitudinal central axis of the opening 4.
In addition, a rotary blade 6 whose outer peripheral blade portion is close to the opening 4 is provided. The rotary blade 6 may be a circular rotary blade (not shown) or may be polygonal as shown in FIG. By using the polygonal rotary blade as described above, the corners can improve the fit with the object 7 to be cut such as cloth, thereby improving the cutting efficiency.

Further, as shown in FIG. 3, a frame 8 is attached to the outside of the main body 1, a motor 9 is installed obliquely thereon, and a shaft 10 of the motor 9 and a shaft 5 which is horizontally mounted on the main body 1 are connected to a flexible shaft 11. The rotation of the motor 9 can be transmitted to the shaft 5. 12 shown in FIGS. 2 and 4 indicates the object 7 to be cut.
The main body, specifically, the rotary blade 6, is located along the cutting line (not shown).
Reference numeral 13 denotes a body lifting piece for forming an air suction gap between the tip of the body and the upper surface of the object 7 to be cut. Although not particularly shown, an ON/OFF switch for the motor 9 is provided on one side of the main body 1 so that the switch can be operated with a fingertip.

Reference numeral 14 shown in FIG. 2 is an adjustment port provided at an arbitrary location on the main body 1, and this adjustment port 14 is provided with an opening/closing plate 15 that slides along the outer surface of the main body.
By opening and closing the adjustment port 14 by operating the opening/closing plate 15, the suction force of outside air from the opening 4, that is, the suction force of the object 7 to be cut is adjusted. For more information,
The suction force from the opening 4 is adapted to the object to be cut 7 depending on the quality, thickness, material, etc. of the object to be cut, so that smooth cutting action can be achieved.

FIG. 5 shows an embodiment in which two rotary blades 6 are attached to the shaft 5, and a cutting line corresponding to the interval between the two rotary blades 6 is provided on the object 7. be. In this case, it goes without saying that the width of the opening 4 is made wider accordingly.

Figures 6 to 8 show the second type with different rotary blade drive mechanisms.
An example is shown below. 16 in FIG. 6 is the main body 1
A shaft 16 is installed vertically inside the shaft 16 so as to coincide with the central axis of the shaft 16. A plurality of sets of propellers 17 are mounted vertically at different angles of 90 degrees to the shaft 16. A plurality of outside air introduction ports 18 are provided at the tip of the main body 1, and the shaft 16 is rotationally driven via a propeller 17 by the wind force sucked through the outside air introduction ports 18. A gear 19 is attached to the lower end of the shaft 16, and is meshed with a crown gear 20 provided on the shaft 5, so that the shaft 5 is rotated.

Further, the embodiment shown in FIG. 7 does not use the rotary blade 6 and shaft 5 shown in the embodiments of FIGS. This conical rotary blade 6a is removably attached.
The object to be cut is continuously cut by the following steps. Since the other mechanisms are the same as those in the embodiment shown in FIG. 6, detailed explanation will be omitted.

In the embodiment shown in FIG. 8, a propeller 21 is provided on a shaft 5 horizontally suspended on the main body 1, and the shaft 5 is moved through the propeller 21 by air sucked from outside air inlets 18a provided on both sides of the tip of the main body 1. It is designed to be rotationally driven.

Next, the cutting action of the present invention will be explained with reference to the representative embodiments shown in FIGS. 2 to 4. As shown in FIG.
When the main body 1 is connected to the cutting line marked on the object 7 to be cut and the indicator 12 provided on the main body 1 is matched to the cutting line, and the motor 9 is driven in this state, the suction device 3 The object to be cut that has been sucked into the body 1 through the opening 4 comes into contact with the rotary blade 6 for initial cutting, and then the body 1 is moved along the cutting line. The object to be cut 7 is smoothly cut by simply moving it, and the debris generated by this cutting passes through the main body 1 and the flexible pipe 2 and is collected by the suction device 3.

It goes without saying that the rotary blade can be rotated by the propeller mechanism shown in Figs. However, since the suction device (not shown) directly connected to the main body can also be used, it is not limited to the illustrated embodiment.

As described above, according to the present invention, by lightly applying the tip of the main body to the object to be cut and moving the main body smoothly along the cutting line, the object to be cut, which is suctioned into the main body through the opening, rotates. The blade cuts smoothly, causing less fatigue compared to conventional cutting methods, and allows for long working hours.It also has the advantage of being able to cut particularly intricate cutting lines quickly without requiring any skill. be.

Furthermore, since the rotating blade is built into the main body, there is no danger at all, and chips and other debris are not dissipated outside but are removed by suction, resulting in a clean working environment and a sanitary environment. There is also.

In particular, it is possible to cut freely even if the object to be cut is placed on the floor or suspended like a curtain, making it easier for clothing designers to dress cloth on models. It has a wide range of uses, such as being suitable for cutting off clothes safely and freely in various situations, or for cutting off the clothing of injured persons in hospitals etc. to quickly expose and treat the affected area. It also has excellent features such as being able to be mass-produced at low cost.
