한편, 이와 같이 이루어지는 플라스틱 골판지의 절곡홈 형성장치에 의해 가공되는 본 발명의 절곡홈이 형성된 골판지는 도 2에 도시된 바와 같이, 통상의 플라스틱 골판지(2)에 있어서, 상기 플라스틱 골판지의 절곡홈 형성장치에 따라 골판지(2)의 절곡부 저면 및 상면으로 서로 마주하는 절곡홈(3)(4)이 형성된 것을 특징으로 한다.On the other hand, the corrugated paper formed with the bending groove of the present invention processed by the bending groove forming apparatus of the plastic corrugated cardboard made in this way, in the conventional plastic corrugated cardboard 2, forming the bending groove of the plastic corrugated cardboard According to the device is characterized in that the bent groove (3) (4) formed to face each other at the bottom and the upper surface of the bent portion of the cardboard (2).

이와 같이 구성된 본 발명의 전체적인 작동관계를 첨부된 도면에 따라서 상세히 설명하면 다음과 같다.When described in detail according to the accompanying drawings the overall operating relationship of the present invention configured as follows.

먼저, 열선(70)에 전원을 인가하여 하부성형틀(50)과 상부성형틀(60)을 성형에 용이한 적정온도로 미리 가열시키고, 그리고 실린더(80)를 작동시켜 상부성형틀(60)을 도 8a에서와 같은 위치로 미리 이동시킨 후, 도 8a에 도시된 바와 같이 골판지(2)를 다이(20)의 상부에 올려놓고 스토퍼(30)와 가이드(40)를 통해 골판지(30)의 위치를 정확하게 정한다.First, the power is applied to the heating wire 70 to heat the lower mold 50 and the upper mold 60 in advance to a suitable temperature for easy molding, and the cylinder 80 is operated to operate the upper mold 60 After moving to a position as shown in Figure 8a in advance, as shown in Figure 8a put the cardboard (2) on top of the die 20 and through the stopper 30 and the guide 40 of the cardboard (30) Accurately position

다이(20)에 골판지(2)를 투입하여 스토퍼(30),가이드(40)에 밀착시킨 상태에서 실린더(80)를 작동시키면 양측 상부성형틀(60)이 수직안내봉(11)을 따라 동시에 하강하면서 도 8b에서와 같이 다이(20)에 올려진 골판지(2)의 절곡부를 누르고, 이에 의해 결과적으로 하부성형틀(50)과 상부성형틀(60)의 성형돌기(51)(61)가 골판지(2)의 상,하부에서 서로 마주한 상태에서 절곡부를 용융시키면서 압착하기 때문에, 골판지(2)의 절곡부 상,하면에는 도 2에서와 같이 열선(70)을 통해 가열된 성형돌기(51)(61)에 의해 절곡홈(3)(4)이 형성된다. When the cylinder 80 is operated by putting the cardboard 2 into the die 20 and being in close contact with the stopper 30 and the guide 40, the upper molds 60 on both sides simultaneously follow the vertical guide rod 11. While lowering, the bent portion of the corrugated cardboard 2 mounted on the die 20 as shown in FIG. 8B is pressed, and as a result, the forming protrusions 51 and 61 of the lower mold 50 and the upper mold 60 are closed. Since the upper and lower sides of the corrugated cardboard 2 are pressed while melting the bent portions, the forming projections 51 heated on the upper and lower surfaces of the corrugated cardboard 2 through the hot wire 70 as shown in FIG. 2. Bending grooves 3 and 4 are formed by 61.                     

골판지(2)의 절곡홈(3)(4)이 형성되면 실린더(80)를 반대로 작동시켜 상부성형틀(60)을 다시 원상태로 이동시키고 이 상태에서 다이(20)에 놓여진 골판지(2)를 빼내면 본 발명의 전체적인 작동이 완료되고, 본 발명은 상기에서와 같은 작동을 반복하면서 골판지(2)의 절곡부에 절곡홈(3)(4)을 형성하게 된다.When the bending grooves 3 and 4 of the corrugated cardboard 2 are formed, the cylinder 80 is operated in reverse to move the upper mold 60 back to the original state, and in this state, the corrugated cardboard 2 placed on the die 20 is removed. When pulled out, the overall operation of the present invention is completed, and the present invention forms the bending grooves 3 and 4 at the bent portion of the cardboard 2 while repeating the above operation.

따라서, 이러한 본 발명에 따르면 플라스틱 골판지(2)의 절곡부에 절곡홈(3)(4)을 형성하기 때문에, 절곡 시 이 절곡홈(3)(4)을 통해 골판지(2)를 한층 더 용이하고도 간편하게 절곡할 수 있는 장점이 있다.Therefore, according to the present invention, since the bent grooves 3 and 4 are formed in the bent portion of the plastic corrugated cardboard 2, the corrugated cardboard 2 is more easily formed through the bent grooves 3 and 4 during bending. And there is an advantage that can be easily bent.

또한 본 발명에 따르면 플라스틱 골판지(2)의 절곡부에 형성된 절곡홈(3)(4)이 절곡되므로, 절곡 후 탄력에 의해 골판지(2)가 다시 펼쳐지는 것을 방지할 수 있는 장점이 있다.In addition, according to the present invention, since the bending grooves 3 and 4 formed in the bent portion of the plastic corrugated cardboard 2 are bent, the corrugated cardboard 2 can be prevented from being unfolded by elasticity after bending.

이상에서 살펴본 바와 같이 본 발명은 플라스틱 골판지의 절곡부에 절곡홈이 형성되기 때문에 골판지를 한층 더 용이하고도 간편하게 절곡할 수 있으며, 또한 플라스틱 골판지의 절곡 후 탄력에 의해 골판지가 다시 펼쳐지는 것을 방지할 수 있는 매우 유용한 발명이다.As described above, the present invention can be folded more easily and simply because the bending grooves are formed in the bent portion of the plastic corrugated cardboard, and also prevent the corrugated cardboard from being unfolded by the elasticity after bending of the plastic corrugated cardboard. Is a very useful invention.
