One side of the main body 10 is provided with a mounting table 12 for stacking a plurality of the styrofoam (S) up and down, and on the opposite side of the mounting table 12 is cut and cut styrofoam (S) It is a configuration in which the discharge table 13 to be installed.

The mounting table 12 is supported by a bearing B such that several supporting rollers 14 are rotatable at both ends of the frame 11 for smooth supply of the styrofoam S to the inlet side of the conveying means 20. And a plurality of guide members 15 on both sides of the support roller 14 so as not to be displaced left and right in the process of being transported to supply the lower styrofoam S1 of the loaded styrofoam S in a loaded state. Is formed.

In addition, the support roller 14 is provided with a styrofoam supply means 40 for entering the styrofoam (S1) in the loaded state to the inlet of the transfer means 20.

The styrofoam supply means 40 is composed of an actuator 41 which is driven by pneumatic or hydraulic pressure, the actuator 41 is located in the center of the mounting table 12 so that the piston rod 42 is directed in the conveying direction. Is installed.

A push rod 43 is installed at an end of the piston rod 42 in an orthogonal direction so that the inner surface of the push rod 43 contacts one end of the styrofoam S1.

Therefore, when the actuator 41 operates, the pusher 43 pushes the styrofoam S1 to the inlet of the transfer means 20.

The rod 43 is configured such that both ends thereof move in a state spanning a pair of guide plates 44 arranged in parallel at intervals from the main body 10 on one side of the support roller 14.

On the other hand, the styrofoam transfer means 20 is for stably transferring the styrofoam (S1) supplied by the actuator 41 to the cutting means 30, the loading table 12 and the discharge table ( 13, a plurality of feed rollers (21, 22) are provided between.

The feed rollers 21 and 22 are arranged at intervals up and down, and are supported by bearings B on the frame 11 at both ends of the rotating shaft 23.

The lower feed rollers 22 are fixed to the frame 11, and the upper feed rollers 21 are supported by bearings B on the gap adjusting plate 24 having the rotating shafts 23 formed thereon. .

And, the gap adjusting plate 24 is coupled to the screw shaft 25 is installed together with the screw shaft 25 installed perpendicular to the main frame 11 between the feed roller 22 in the lower side is the screw shaft Spacing adjustment handle 27 is coupled to (25).

Accordingly, when the gap adjusting handle 26 is tightened or released, the gap adjusting plate 24 supported by the boss portion 26a of the gap adjusting handle 26 is upwardly shot by the resilient member 26. The distance between the feed rollers 21 and 22 can be selectively adjusted according to the thickness of the styrofoam S1.

The elastic member 26 is composed of a coil spring.

In addition, the feed rollers (21, 22) to the power transmission member (3) to be rotated in the same direction and at the same speed by the drive device (2) having a reducer (1) provided below the main body (10) It is connected and interlocked.

The power transmission member 3 is composed of a chain caught on a sprocket (not shown) coupled to the rotating shaft 23 of the feed rollers 21 and 22 to rotate the feed rollers 21 and 22 at a constant speed.

A sensor 28 is installed between the feed rollers 21 and 22 at the inlet side to detect the presence or absence of the styrofoam S1 supplied from the mounting table 12.

Therefore, the driving device 2 is operated by the detection signal of the sensor 28 to drive the feed rollers 21 and 22 only when the styrofoam S1 is supplied.

Meanwhile, the cutting means 30 heat-cuts the styrofoam S1 in a predetermined cross-sectional shape while being installed at the center between the feed rollers 21 and 22 and transferred to a pair of electrode plates 31 and a heating wire. It consists of a fixing stand 32 and a heating wire 33.

The electrode plate 31 is installed between the feed rollers 21 and 22 with the insulator 32a interposed between the electrode plate holders 32 provided on the main frame 11, and power lines 34 at each end. Are applied respectively.

The upper and lower portions of the electrode plate 31 are provided with a coil-shaped hot wire fixing rod 34 for hanging and fixing the hot wire 33.

Since the heating wire 33 is cut by heating the styrofoam (S1) transferred between the feed rollers (21, 22) in a predetermined cross-sectional shape to adjust the tension applied to the heat wire fixing stand 34 at both ends in order to maintain an appropriate tension. The members 35 are each connected.

Therefore, the heating wire 33 is installed by moving the position on the heating wire fixing stand 34 in accordance with the cross-sectional shape of the styrofoam S1. For example, in FIG. In addition to the rectangular and trapezoidal shapes as shown in the figure can be installed to cross to form a variety of shapes such as right triangle, equilateral triangle, polygonal shape so that the styrofoam (S) can be cut in various forms accordingly.

The driving device 3, the sensor 28, and the actuator 41 are electrically connected to the control unit 60 provided on one side of the main body 10 so as to be mutually operated.

Here, the power applied to the heating wire 33 also maintains a constant temperature at all times by the temperature control operation to the control unit 60.

And, one side of the heating wire 33 is provided with a blowing means 50, the blowing means 50 is connected to the blower fan (not shown) to be operated by the control unit 60 is connected to the hose This is to allow the cross-sectional area cut by the heating wire 33 to be cooled rapidly by blowing to the heating wire side through the 51.

Referring to the operation of the styrofoam cutting device of the present invention configured as described in detail as follows.

First, the operator arranges a plurality of styrofoams (S) on the mounting table 12 well.

Next, when the control unit 60 is operated, the actuator 41 is first driven to move the piston rod 42, so that the styrofoam S1 at the bottom of the push rod 43 is moved toward the feed rollers 21 and 22. Will be transferred.

Here, the moment the front end of the styrofoam (S1) passes between the first feed rollers (21, 22) the sensor 28 is demagnetized to send the signal to the control unit 60 and then the control unit 60 The piston rod 42 is positioned in an initial state as the actuator 41 reverses operation.

At the same time, the drive device 2 is operated by receiving the drive signal from the sensor 28 so that the rotational force decelerated by the speed reducer 1 is transmitted to the feed rollers 21 and 22 by the power transmission member 3. Therefore, the feed rollers 21 and 22 are all rotated at constant speed in the same rotational direction.

Therefore, the styrofoam (S1) is conveyed to the heating wire 33 side while maintaining a constant speed slowly by the feed rollers (21, 22).

The styrofoam (S1) to be transferred is cut into a predetermined cross-sectional shape, as shown in Figure 7 (b) as the front end passes through the hot wire 33 and is discharged to the discharge table 13, Figure 6 Styrofoam of the plate shape is cut as shown.

Next, if the styrofoam (S1) exits in the above process, the styrofoam (S) on the above fall back down by its own weight.

And, the end of the styrofoam (S1) to be cut passes the sensor 28 and at the same time the actuator 41 is initially operated again to transfer the bottom styrofoam (S) between the transfer rollers (21, 22) as described above. By supplying, it is possible to continuously cut automatically by the same operation as described above.

On the other hand, if you want to change the cross-sectional shape of the styrofoam (S) in the cutting process can be cut by adjusting the arrangement of the heating wire (33).

In addition, in order to cut the styrofoam of different thickness, tighten or loosen the gap adjusting handle 27 to adjust the gap between the transfer rollers 21 and 22 to match the thickness of the styrofoam to be cut and then perform the above operation. Just do it.

According to the above description, in the present invention, when cutting a styrofoam made of a plate shape in a lengthwise direction, hot wires which are sequentially cut by a feeder by supplying styrofoam having very poor cutting workability by a conveying means are cut by a worker. By passing through and cutting between, you can get a smooth section of a very good condition, and you can cut selectively regardless of thickness, and freely and easily cut into various cross-sectional shapes such as rectangles, trapezoids, various triangles and polygons. The effect is that you can automatically cut continuously.
