본 고안은 폐수지 재생용 용융수지 어큐물레이터(Accumlator)에 관한 것이다.The present invention relates to a melt accumulator for waste resin recycling.

통상적으로 폐수지를 재생할 경우 수지를 녹여 용융된 수지를 사출 및 압출 등을 행할 때 냉각등의 일정한 작동상 시간이 소요되므로 이 경우 수지를 연속적으로 녹일 수 없게 되어 작업이 원활하게 이루어지지 못한다. 따라서 대형 제품을 생산하고자 할 때 수지를 간헌적으로 용융시켜야 함으로 큰 능률이 오르지 못하는 단점이 있다.In general, when the waste resin is recycled, it takes time for constant operation such as cooling when dissolving the resin to inject and extrude the molten resin, and in this case, the resin cannot be continuously melted, and thus the work cannot be smoothly performed. Therefore, when producing a large product, the resin has to be melted constitutionally, so there is a disadvantage that the large efficiency does not rise.

본 고안은 수지의 용융과, 사출 압축작업이 연속적으로 이루어지도록 하여 대형 수지제품의 생산성을 향상시킨 어큐물레이터에 관한 것으로 이하 첨부도면과 함께 상술한다.The present invention relates to an accumulator which improves the productivity of a large-scale resin product by melting the resin and injection-compressing continuously, and will be described in detail with the accompanying drawings.

제1도는 본 고안의 어큐물레이터에 대한 개략 사시도로서, 자체적으로 거의 Y형태로 이루어지며, 좌우측으로 내각선으로 각각 비스듬하게 피스톤이 내장된 형태로 되어 있다. 그리고 그 하부엔 제2도와 같은 사출챔버(1)가 관통 연결된다.1 is a schematic perspective view of the accumulator of the present invention, which is almost Y-shaped in itself, and has a form in which pistons are inclined at an angle to the left and right sides. And the lower part of the injection chamber 1 as shown in Figure 2 is connected through.

제2도는 제1도의 호퍼에 사출챔버(1)가 일체로 연결된 상태를 나타내는 단면도이다.2 is a cross-sectional view showing a state in which the injection chamber 1 is integrally connected to the hopper of FIG.

호퍼(2) 내부엔 피스톤(21, 22)이 내장되고 피스톤(21, 22)은 고정된 피스톤 로드(21A, 22A)를 따라 승하강한다. 승하강 동작은 상단에서 호퍼(2) 내부로 가해지는 유압 즉, 피스톤 로드(21A, 22A)의 중심구멍을 따라 유입된 유압으로 피스톤(21, 22)이 피스톤 로드(21A, 22A)를 따라 승하강 왕복운동을 한다.The pistons 21 and 22 are built in the hopper 2 and the pistons 21 and 22 are raised and lowered along the fixed piston rods 21A and 22A. The lifting and lowering operation is the hydraulic pressure applied to the inside of the hopper 2 at the upper end, that is, the hydraulic pressure introduced along the center hole of the piston rods 21A and 22A. The pistons 21 and 22 move up and down the piston rods 21A and 22A. Do a downward reciprocating motion.

사출챔버(1) 내부엔 스파이어럴 나사(31) 외형을 갖는 피스톤(32)이 내장되어 있다.Inside the injection chamber 1, a piston 32 having an external shape of a spiral screw 31 is incorporated.

한편 Y형태의 호퍼(2) 표면엔 소정의 위치에 히터(4)가 설치되어 용융수지가 굳어지는 것을 방지한다. 또한 도시하지 않았지만 피스톤(21, 22)의 외면엔 냉각수가 유압, 유출되는 순환경로를 형성시켜 피스톤(21, 22)과 호퍼(2)의 내면이 수지와 함께 붙는 것을 방지하도록 한다.On the other hand, the heater 4 is provided in the predetermined position on the surface of the hopper 2 of a Y shape, and it prevents a molten resin from hardening. In addition, although not shown, the outer surfaces of the pistons 21 and 22 form a circulation path through which the coolant flows hydraulically and outflow to prevent the inner surfaces of the pistons 21 and 22 and the hopper 2 from sticking together with the resin.

이상과 같은 본 고안의 구성에 의한 동작관계를 설명한다.The operation relationship by the configuration of the present invention as described above will be described.

먼저 용융된 수지를 제1도에 나타낸 바와 같은 Y자 형태의 중앙 개구로 연속 공급한다. 공급된 용융수지는 1차로 좌측의 피스톤(21)의 유압에 의한 미는 동작으로 용융된 수지를 우측으로 밀어준다. 이때 우측의 피스톤(22)은 상승된 위치에 있다. 좌측 피스톤(21)의 미는 동작이 완료된 후 후퇴하는 시점에 우측의 피스톤(22)이 하강하여 우측으로 밀려 내려온 용융수지를 사출챔버(1) 속으로 밀어 넣는다.Firstly, the molten resin is continuously fed to the Y-shaped central opening as shown in FIG. The supplied molten resin primarily pushes the molten resin to the right by pushing the hydraulic pressure of the piston 21 on the left side. At this time, the piston 22 on the right side is in an elevated position. At the time of retraction after the pushing operation of the left piston 21 is completed, the right piston 22 descends and pushes the molten resin pushed down to the right into the injection chamber 1.

이와 같은 동작이 반복되는 동안 사출챔버(1) 내의 피스톤(32)은 회전한다. 그러면 외면에 형성시킨 스파이어럴 나사(31)에 의해 용융수지가 사출챔버(1)의 전방으로 밀려 전방으로 몰려 모이게 된다. 일정량의 수지가 모이면 피스톤(32)의 회전동작이 왕복운동으로 바뀌어져 사출챔버(1) 일측에 모여 있는 용융된 수지를 챔버(1) 밖으로 배출시켜 성형장치 내로 연속 공급된다.The piston 32 in the injection chamber 1 rotates while this operation is repeated. Then, the molten resin is pushed toward the front of the injection chamber 1 by the spiral screw 31 formed on the outer surface, and gathered forward. When a certain amount of resin is collected, the rotational motion of the piston 32 is changed to reciprocating motion, and the molten resin collected on one side of the injection chamber 1 is discharged out of the chamber 1 and continuously supplied into the molding apparatus.

한편 피스톤(21, 22)의 운동에 사용되는 유체는 오일 기름등의 액체 또는 기체를 사용한다.On the other hand, the fluid used for the movement of the pistons 21 and 22 uses a liquid or gas such as oil or oil.

이상과 같은 본 고안의 구성에 의하면 용융된 수지를 연속적으로 성형장치에 공급할 수 있어 대형 수지 성형물을 제작할 때 작업성이 향상되고 또한 Y형태 호퍼 중앙의 용융 수지통은 상방향으로 개구되어 있어 용융 수지에서 발생되는 폐수지의 개스가 대기로 방출되므로 수지 성형물내에 발생하기 쉬운 기포등의 발생도 상당히 줄일 수 있는 효과가 있다.According to the configuration of the present invention as described above, the molten resin can be continuously supplied to the molding apparatus, and the workability is improved when producing a large resin molded article, and the molten resin barrel in the center of the Y-shaped hopper is opened upwards, so that the molten resin Since the gas of the waste resin generated in the gas is discharged into the atmosphere, it is possible to considerably reduce the occurrence of bubbles and the like that are easily generated in the resin molding.
