Description

합성수지 불순물 제거장치Synthetic Resin Impurity Removal Device
본 발명은 합성수지 불순물 제거장치에 관한 것으로, 보다 상세하게는 사출이나 압출공정 등의 중단없이 수지에 포함된 불순물을 효과적으로 제거하여 제품의 품질 및 생산성을 향상시킬 수 있는 합성수지 불순물 제거장치에 관한 것이다.The present invention relates to a synthetic resin impurity removing apparatus, and more particularly, to a synthetic resin impurity removing apparatus that can effectively remove impurities contained in the resin without interruption of an injection or extrusion process to improve product quality and productivity.
일반적으로 합성수지를 이용한 제품의 압출성형은 원재료인 합성수지를 가열, 용융시켜 소정의 단면 형상을 가지도록 압출시키는 것으로, 도 1과 같은 압출기를 이용하여 압출하게 된다. In general, extrusion of a product using a synthetic resin is to extrude to have a predetermined cross-sectional shape by heating and melting the synthetic resin as a raw material, it is extruded using an extruder as shown in FIG.
도 1에 도시된 종래의 압출기(1)는 용융수지를 스크류(2)를 이용하여 이송시키는 원통형 실린더(3)가 구비되고, 이 실린더(3)의 선단에는 플랜지(4)가 일체로 형성되며, 플랜지(4)의 선단에는 용융수지를 소정의 형태로 압출하기 위한 다수의 압출공(7)이 형성된 압출다이스(8)가 고정 결합된다. The conventional extruder 1 shown in FIG. 1 is provided with a cylindrical cylinder 3 for conveying molten resin using a screw 2, and a flange 4 is integrally formed at the front end of the cylinder 3. At the tip of the flange 4, an extrusion die 8 having a plurality of extrusion holes 7 for extruding the molten resin in a predetermined form is fixedly coupled.
상기 플랜지(4)의 내부에는 합성수지를 용융시켜 압출하는 과정에서 용융수지에 함유된 다양한 종류의 불순물 또는 용융과정에서 탄화된 불순물 등을 제거하여 추후공정에서 불순물 유입에 따른 불량을 미연에 방지하기 위해 타공이 형성된 스크린(5)과 이 스크린(5)이 제 형상을 유지할 수 있도록 하는 스크린베이스(6)를 개재한다.In the inside of the flange 4 to remove various kinds of impurities contained in the molten resin or carbonized impurities in the melting process in the process of melting and extruding the synthetic resin to prevent defects due to the inflow of impurities in a later process It interposes the screen 5 in which the perforation was formed, and the screen base 6 which enables this screen 5 to maintain a shape.
그런데, 압출공정이 연속적으로 이루어질 때 상기 스크린(5)의 타공에 불순물이 계속적으로 걸러짐에 따라 스크린(5)의 타공이 막히게 되어 스크린(5)을 주기적으로 교체 또는 청소해야 하기 때문에 압출기(1)의 작동을 주기적으로 정지시켜야 하므로 작업효율성이 떨어지고 생산성이 저하되는 문제가 있다. 특히, 재활용 합성수지를 사용하는 경우에는 세척과정을 거친다 하더라도 불순물을 완전하게 제거하지 못하기 때문에 용융수지에 함유된 불순물로 인해 스크린(5)의 타공 부위가 차단되는 시간이 짧아지게 되므로, 스크린(5)의 교체 또는 청소주기가 짧아져서 스크린(5) 교체나 청소를 위하여 압출기(1)의 작동을 정지시키는 비 가동시간이 더 길어지게 되어 생산성 저하가 더욱 두드러지며 그로 인해 생산원가가 상승되어 가격경쟁력이 저하되는 문제가 있다. 상기에서는 압출기를 예시하였으나 사출기 등 합성수지를 이용한 성형장치에서 동일한 문제가 발생한다.However, when the extrusion process is continuously performed, as the impurities are continuously filtered through the perforations of the screen 5, the perforations of the screen 5 are blocked and the screen 5 needs to be replaced or cleaned periodically. ) Must be stopped periodically, there is a problem that the work efficiency is lowered and productivity is lowered. In particular, in the case of using recycled synthetic resins, impurities cannot be completely removed even after the washing process, so that the time for blocking the perforations of the screen 5 is shortened due to impurities contained in the molten resin. ) The shorter the downtime of stopping extruder 1 to replace or clean the screen (5) due to the shorter replacement or cleaning cycle, the lower the productivity is more prominent, which leads to higher production cost This has a problem of deterioration. Although the extruder is exemplified above, the same problem occurs in a molding apparatus using a synthetic resin such as an injection machine.
본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 압출이나 사출공정 등의 중단없이 수지에 포함된 불순물을 효과적으로 제거하여 제품의 품질 및 생산성을 향상시켜 가격경쟁력을 높일 수 있는 합성수지 불순물 제거장치를 제공하는 것에 있다.The present invention is to solve the above problems, the object of the present invention is to effectively remove impurities contained in the resin without interruption of the extrusion or injection process, etc. to improve the quality and productivity of the product to increase the price competitiveness A resin impurity removal device is provided.

The outer cylinder 20 is formed in a cylindrical shape extending substantially back and forth, the inlet 21 is formed in the molten resin is injected into the rear peripheral surface and the impurity outlet for discharging the impurities (9) contained in the molten resin at the front end (22) is formed. In addition, a resin discharge port 23 through which the molten resin from which the impurities 9 have been removed is discharged is formed in the middle circumferential surface of the outer cylinder 20.
상기 타공드럼(30)은 용융수지는 통과하고 용융수지에 함유된 불순물(9)이 걸러지는 미세한 타공(31)이 형성된 것으로, 양단이 개방된 원통체 형상으로 이루어져서 외통체(20) 내부에 전후로 배치되도록 고정 설치된다. 이때, 타공드럼(30)의 타공(31)을 통해 수지가 원활히 배출되도록 타공드럼(30)의 둘레면이 외통체(20)의 내주면과 소정간격 이격되도록 설치하는 것이 바람직하다. 이와 같이 설치된 타공드럼(20)의 개방된 후단이 외통체(20)의 주입구(21)와 연통되는 투입구(32)를 이룬다. The perforated drum 30 is formed with a fine perforated 31 through which the molten resin passes and the impurities 9 contained in the molten resin are filtered out. The perforated drum 30 is formed in a cylindrical shape with both ends open and then moved back and forth inside the outer cylinder 20. It is fixed to be placed. At this time, the periphery of the perforated drum 30 is preferably installed to be spaced apart from the inner circumferential surface of the outer cylinder 20 so that the resin is smoothly discharged through the perforated 31 of the perforated drum 30. The open rear end of the perforated drum 20 installed in this way forms an inlet 32 which communicates with the inlet 21 of the outer cylinder 20.
상기 이송스크류(40)는 회전축(41)과, 이 회전축(41)의 둘레면에 돌출 구비된 이송날개(42)로 이루어져서 회전축(41)이 타공드럼(30)의 내부에 전후로 설치된다. 상기 구동수단(50)은 회전축(41)을 회전시키는 것으로 구동모터 및 기어, 체인이나 벨트 등과 같은 구성품으로 이루어지며 회전축(41)이 구동모터와 축결된다. 이때, 상기 구동수단(50)은 외통체(20) 및 타공드럼(30)의 후방에 설치된다. The conveying screw 40 is composed of a rotating shaft 41 and the transfer blade 42 protruding on the circumferential surface of the rotating shaft 41, the rotating shaft 41 is installed in the perforated drum 30 back and forth.

At this time, the driving means 50 is installed at the rear of the outer cylinder 20 and the perforated drum 30.
이와 같이 구성된 이송스크류(40)가 구동수단(50)에 의해 회전됨에 따라 타공드럼(30) 내부로 유입된 용융수지가 타공드럼(30)의 전단으로 이송된다. 한편, 상기 회전축(41)은 기단에서 선단으로 갈수록 직경이 확장되는 형상으로 이루어진다. 이에 따라, 이송되는 용융수지는 이송스크류(40)의 전단으로 이송될수록 타공드럼(30)의 내벽에 압착되므로 타공드럼(30)의 타공(31)을 통과하여 수지배출구(23)를 통해 배출된다. 이때, 용융수지에 함유된 불순물(9)은 타공드럼(30)의 타공(31)을 통과하지 못하므로 이송스크류(40)에 의해 계속 이송되어 외통체(20) 전단의 불순물배출구(22)를 통해 외부로 배출된다.As the transfer screw 40 configured as described above is rotated by the driving means 50, the molten resin introduced into the perforated drum 30 is transferred to the front end of the perforated drum 30. On the other hand, the rotating shaft 41 is formed in a shape in which the diameter extends from the base end to the tip. Accordingly, the transferred molten resin is compressed to the inner wall of the perforated drum 30 as it is transferred to the front end of the transfer screw 40, and then passed through the perforated 31 of the perforated drum 30 and discharged through the resin outlet 23. . At this time, since the impurity 9 contained in the molten resin does not pass through the perforation 31 of the perforated drum 30, the impurity outlet 22 of the front end of the outer cylinder 20 is continuously transferred by the transfer screw 40. Through the outside.
한편, 타공드럼(30)의 투입구(32)보다 후방에 위치된 회전축(41)은 직경이 확장되어 외통체(20)의 내주면과 거의 밀착되도록 형성된다. 또한, 상기와 같이 후방에 위치한 회전축(41)에는 상기 이송날개(42)들 간의 간격보다 간격이 보다 촘촘히 형성된 다수의 차단날개(43)가 구비되어, 타공드럼(30)의 투입구(32)로 과도한 양의 용융수지가 유입되더라도 이송스크류(40)의 후방으로 밀려나는 것이 효과적으로 차단된다. On the other hand, the rotary shaft 41 located behind the inlet 32 of the perforated drum 30 is formed to be in close contact with the inner circumferential surface of the outer cylinder 20 is expanded in diameter. In addition, the rotary shaft 41 located at the rear as described above is provided with a plurality of blocking wings 43 formed more tightly than the interval between the transfer blades 42, the inlet 32 of the perforated drum 30 Even when an excessive amount of molten resin is introduced, it is effectively blocked from being pushed to the rear of the transfer screw 40.
