Description

노브러시 자동 세차기의 분사노즐 회동장치Spray Nozzle Rotator of Nozzle Auto Washing Machine
본 발명은 노브러시 자동 세차기의 분사노즐 회동장치에 관한 것으로, 더욱 상세하게는 분사노즐이 일시 멈춤 없이 연속 회동 가능케 함으로써 차량 표면의 얼룩 발생을 방지하고, 분사노즐의 고속 회동이 가능케 하여 세차 속도를 향상시키며, 분사노즐에 세척수를 공급하는 연결호스의 유동을 억제하여 연결호스의 꼬임이나 손상을 방지할 수 있게 한 노브러시 자동 세차기의 분사노즐 회동장치에 관한 것이다.The present invention relates to a spray nozzle rotating device of a nozzle automatic car wash, and more particularly, to prevent the occurrence of stain on the surface of the vehicle by allowing the spray nozzle to rotate continuously without pausing, and to enable the high-speed rotation of the spray nozzle to wash the car. The present invention relates to a spray nozzle rotating device of a nouveau automatic car wash which improves and suppresses the flow of the connecting hose supplying the washing water to the spray nozzle, thereby preventing the connecting hose from being twisted or damaged.
자동 세차기는 도 1과 같이 차량의 외관을 자동으로 세차하는 장치로서, 일반적으로 세차기 본체(1)가 지면에 설치된 레일을 따라 왕복하면서 세차가 이루어지는 문주형과, 차량이 이송장치에 의해 세차기 본체 내부를 일방향으로 통과하는 동안 세차가 이루어지는 터널형이 있다.The automatic car wash is a device for automatically washing the exterior of a vehicle as shown in FIG. 1, and in general, a door mold in which the car wash body 1 is reciprocated along a rail installed on the ground, and the vehicle is moved by the conveying device to the inside of the car wash body. There is a tunnel type where washing is performed while passing in one direction.
이러한 자동 세차기는 본체에 세척수를 분사하는 세척수 분사노즐이 구비되어, 세척수를 분사하여 차량 표면의 흙이나 모래 등 각종 오염물을 1차 제거한 후, 브러싱수단을 이용해 차량 표면을 문질러 오염물을 2차 제거하고, 헹굼수 분사노즐을 이용해 헹굼수를 분사하여 오염물을 최종 제거한 후, 드라잉수단을 이용해 차량 표면의 물기를 제거함으로써 자동 세차가 완료된다.The automatic car wash is equipped with a washing water spray nozzle for spraying the washing water to the main body, and sprays the washing water to remove various soils such as dirt or sand on the surface of the vehicle, and then rubs the surface of the vehicle with a brushing means to remove the second soil. After the final removal of contaminants by spraying the rinsing water using the rinse water injection nozzle, automatic washing is completed by removing water from the surface of the vehicle using a drying means.
그런데 위와 같은 종래의 자동 세차기는 세척수를 이용해 1차로 오염물을 제거하는 과정에서는 단순히 물을 고르게 뿌려주는 정도이기 때문에 차량 표면의 오염물이 완전하게 제거되지 않는데, 그러한 상태에서 브러싱수단에 의해 2차로 오염물을 제거하는 과정을 수행하게 되면, 차량 표면에 잔류한 오염물이 브러싱수단에 의해 차량 표면과 마찰하면서 차량 표면에 미세한 흠집이 발생하는 단점이 있다. However, the above-described conventional automatic car wash does not completely remove the contaminants on the surface of the vehicle since it is simply sprayed with water evenly in the process of removing the contaminants first by using the washing water. When the removal process is performed, fine scratches are generated on the surface of the vehicle while the dirt remaining on the surface of the vehicle rubs against the surface of the vehicle by the brushing means.
그리하여 근래에는 브러싱수단 없이 분사노즐을 이용해 세척수를 고압으로 분사함으로써, 세척수의 분사압력을 이용해 차량 표면의 오염물을 완전히 제거하는 노브러시 자동 세차기가 개발된 바 있다. Thus, in recent years, a nouveau automatic car wash has been developed by spraying the washing water at a high pressure using a spray nozzle without brushing means, and completely removing contaminants on the vehicle surface using the spraying pressure of the washing water.
따라서 노브러시 자동 세차기는 세차 성능의 향상을 위해서 세척수를 고압으로 분사하는 분사노즐의 기능이나 성능이 중요하다.Therefore, the function and performance of the nozzle nozzle for spraying the washing water at high pressure is important for improving the car wash performance.
그리하여 종래에는 주로 분사노즐의 분사 압력을 높이는 방향으로 기술개발이 이루어졌으며, 보다 신속한 세차를 위하여 다수의 분사노즐을 설치하게 되었다. Thus, in the related art, technical development has been mainly performed in the direction of increasing the injection pressure of the injection nozzle, and a plurality of injection nozzles have been installed for more rapid washing.
그런데, 종래의 노브러시 자동 세차기는 분사노즐이 소정 간격으로 다수 개가 고정 설치됨으로써 세척수에 의해 차량 표면에서 분리된 오염물이 세척수와 함께 쉽게 흘러내리지 못하고 차량 표면에 잔류하는 단점이 있다.However, the conventional nozzle automatic car wash has a disadvantage in that a plurality of spray nozzles are fixedly installed at predetermined intervals and contaminants separated from the vehicle surface by the washing water do not easily flow together with the washing water and remain on the vehicle surface.
즉, 소정 간격으로 고정 설치된 분사노즐에서 고압으로 세척수가 분사되는 동안에 차량이 세차기 본체를 통과하게 되면, 세척수의 분사 형태가 차량에 대하여 가로 방향으로 일직선 형태가 된다.That is, when the vehicle passes through the car wash body while the washing water is injected at a high pressure from the spray nozzles fixedly installed at predetermined intervals, the spraying form of the washing water is straight in the transverse direction with respect to the vehicle.
따라서 세척수에 의해 차량 표면에서 분리된 이물질은 차량 아래로 흘러내리지 못하고, 가로 방향으로 일직선 형태가 되는 분사 형태를 따라 가로 방향으로 계속 밀려나면서 결국 차량의 후측 표면에 잔류함으로써, 세차가 깨끗하게 이루어지지 못하는 단점이 있다.Therefore, foreign matter separated from the surface of the vehicle by the wash water does not flow down the vehicle, and continues to be pushed in the horizontal direction along a spray form that is straight in the horizontal direction, and eventually remains on the rear surface of the vehicle, thereby preventing the washing from being performed cleanly. There are disadvantages.
또한, 분사노즐에서 분사되는 세척수의 분사 형태는 분사노즐을 기준으로 원뿔 형태로 분사된다.In addition, the spray form of the washing water sprayed from the spray nozzle is sprayed in the form of a cone based on the spray nozzle.
즉, 원뿔 형태의 꼭짓점이 분사노즐이 되고, 원뿔 형태의 밑면이 차량 표면에 세척수가 닿는 실제 분사면적이 되는데, 이때 원뿔의 밑면에 해당하는 분사면적의 중앙은 세척수의 분사압력이 강하여 차량 표면의 오염물이 쉽게 제거되는 반면, 분사면적의 가장자리로 갈수록 분사압력이 약해짐으로써, 오염물이 쉽게 제거되지 않아 오염물의 제거 정도의 차이로 인해 얼룩이 발생하는 단점이 있다. In other words, the cone-shaped vertex becomes the spray nozzle, and the cone-shaped bottom surface becomes the actual sprayed area where the wash water touches the surface of the vehicle. At this time, the center of the sprayed area corresponding to the bottom of the cone has a strong spraying pressure of the wash water. While the contaminants are easily removed, the injection pressure is weakened toward the edge of the injection area, so that the contaminants are not easily removed and stains occur due to differences in the degree of removal of the contaminants.
상기와 같은 세척수의 분사 압력 편차에 따른 얼룩 발생을 방지하기 위해, 종래의 노브러시 자동 세차기는 다수의 분사노즐을 소정 간격으로 설치할 때, 각 분사노즐에서 분사되는 세척수의 분사면적이 부분적으로 중첩되게 함으로써, 분사 압력의 편차에 따른 얼룩 발생을 최소화할 수 있도록 설계가 이루어지고 있다. In order to prevent staining caused by the variation in the spray pressure of the washing water as described above, when a plurality of spray nozzles are installed at predetermined intervals, the spray area of the washing water sprayed from each spray nozzle is partially overlapped. By doing so, the design is made so as to minimize the occurrence of spots due to the variation in the injection pressure.
그럼에도 불구하고, 세척수의 분사 압력 편차에 의한 얼룩 발생을 방지하는 것이 쉽지 않아, 근래에는 분사노즐에서 세척수가 분사되는 동안에 분사노즐을 상하로 회동시키는 노브러시 자동 세차기의 분사노즐 회동장치가 개발된 바 있다.Nevertheless, it is not easy to prevent the occurrence of stains due to the variation in the spray pressure of the washing water. Recently, a spray nozzle rotating device of a nozzle auto washing machine that rotates the spray nozzle up and down while the washing water is sprayed from the spray nozzle has been developed. have.
즉, 회동수단을 이용해 분사노즐을 상하로 회동시킴으로써, 차량 표면에 분사되는 세척수의 분사 형태가 지그재그 형태가 되게 하여 차량 표면에서 분리된 오염물이 차량 표면에서 아래로 보다 쉽게 흘러내리도록 함과 동시에, 세척수의 분사압력 편차에 따른 얼룩 발생을 방지할 수 있게 한 것이다. That is, by rotating the spray nozzle up and down using the rotation means, the spray form of the washing water sprayed on the vehicle surface becomes a zigzag form, and at the same time the contaminants separated from the vehicle surface more easily flow down from the vehicle surface, It is to prevent the occurrence of stains due to the variation in the injection pressure of the washing water.
그런데, 종래의 분사노즐 회동장치는 실린더를 이용해 다수의 분사노즐을 회동시킴으로써, 회동 속도가 느리기 때문에 저속으로 회동하는 분사노즐에서 분사되는 세척수를 차량 표면에 고르게 분사하기 위해서는 차량의 저속 이동이 불가피하고, 그로 인해 세차 속도가 느려지는 단점이 있다. However, in the conventional injection nozzle rotating device, a plurality of injection nozzles are rotated by using a cylinder, and thus, the rotational speed is low, so that the low speed movement of the vehicle is inevitable in order to evenly spray the washing water sprayed from the injection nozzle rotating at a low speed to the surface of the vehicle. This has the disadvantage of slowing down the car wash speed.
자동 세차기의 세차 속도가 빠를수록 정해진 시간 내에 더 많은 차량을 세차할 수 있기 때문에 세차 속도는 자동 세차기를 운용하는 사업주 입장에서 생산성 및 수익성과 직결되는 문제로서, 세차 속도가 느려지는 것은 매우 중대한 단점으로 작용하게 된다.Because the faster the car wash speed, the more car washes can be done within a given time, so the speed of car wash is directly related to productivity and profitability for the owners of automatic car washes. It will work.
또한, 종래의 분사노즐 회동장치는 실린더를 이용해 회동시킴으로써, 실린더의 피스톤로드가 투입, 배출이 반복되는 과정에서 압력 제어에 필요한 시간 지연으로 인해 상사점과 하사점에서 피스톤로드가 짧은 시간 동안 일시적 멈춤 현상이 발생하게 된다. In addition, in the conventional injection nozzle rotating device, the piston rod is temporarily stopped at the top dead center and the bottom dead center for a short time due to the time delay required for pressure control in the process of repeatedly inserting and discharging the piston rod of the cylinder. The phenomenon occurs.
따라서 상기와 같이 실린더의 일시적 멈춤 현상이 발생하게 되면, 도 2와 같이 차량이 진행하는 동안에 일시적으로 분사노즐이 제자리에 정지하면서, 세척수의 분사 형태가 가로 방향으로 일직선 형태(A)가 됨으로써, 일부 오염물이 차량 표면에서 가로 방향으로 밀리면서 잔류하는 단점이 있다.Therefore, when the temporary stoppage of the cylinder occurs as described above, while the injection nozzle is temporarily stopped while the vehicle proceeds as shown in FIG. 2, the injection form of the washing water becomes a straight form A in the horizontal direction. The disadvantage is that dirt remains on the vehicle's surface in the transverse direction.
또한, 분사노즐의 일시적 멈춤 현상이 발생함에 따라 세척수의 분사압력 편차에 따른 얼룩이 발생하는 단점이 있다.In addition, there is a disadvantage in that a stain according to the variation in the injection pressure of the washing water occurs as a temporary stop phenomenon of the injection nozzle.
또한, 종래의 분사노즐 회동장치는 분사노즐을 회동시키는 과정에서 분사노즐과 연결된 연결호스가 반복적으로 유동하면서 노후화가 가속되어 균열에 따른 누수가 발생하거나, 꼬임이 발생하면서 고압을 견디지 못하고 연결호스가 터지는 단점도 있다.In addition, in the conventional injection nozzle rotating device, the connection hose connected to the injection nozzle is repeatedly flowed in the process of rotating the injection nozzle to accelerate the aging, causing leakage due to cracking or twisting. There are also disadvantages to popping.

도 3 내지 도 6을 참조하여 설명한다. This will be described with reference to FIGS. 3 to 6.
본 발명의 노브러시 자동 세차기의 분사노즐 회동장치는 회전관(20), 세척수공급라인(30), 분사노즐(40), 회동수단(50)을 포함한다.The spray nozzle rotating device of the nozzle automatic car wash of the present invention includes a rotary tube 20, the washing water supply line 30, the spray nozzle 40, the rotating means (50).
상기 회전관(20)은 자동 세차기의 본체프레임(10)에서 세로 방향을 따라 소정 간격으로 다수가 각각 회전 가능케 설치된다. The rotary tube 20 is rotatably installed in a plurality at predetermined intervals along the longitudinal direction in the main frame 10 of the automatic car wash.
각 회전관(20)은 상기 본체프레임(10)을 관통하게 설치되되, 본체프레임(10)의 양면에는 상기 회전관(20)의 양단부를 각각 회전 가능케 지지하는 베어링유닛(201)을 설치함으로써, 회전관(20)은 축중심을 기준으로 하여 원활한 회전이 가능케 된다.Each rotary tube 20 is installed to penetrate the main body frame 10, by installing bearing units 201 rotatably supporting both ends of the rotary tube 20 on both sides of the main body frame 10, The rotary tube 20 allows smooth rotation based on the axis center.
이때, 상기 회전관(20)의 양단부에는 상기 세척수공급라인(30) 또는 분사노즐(40)의 결합을 위하여 나사부를 형성하는 것이 바람직하다. At this time, it is preferable to form a screw for coupling the washing water supply line 30 or the spray nozzle 40 at both ends of the rotary tube (20).
상기 세척수공급라인(30)은 상기 각 회전관(20)의 일단부에 연결되어 회전관(20)에 세척수를 공급하기 위해 공급관(301), 로터리조인트(302), 연결호스(303)를 포함한다.The washing water supply line 30 is connected to one end of each of the rotary tube 20 includes a supply pipe 301, a rotary joint 302, a connection hose 303 to supply the washing water to the rotary tube 20 do.
상기 공급관(301)은 세척수공급펌프(도시하지 않음)에서 소정 압력으로 세척수가 공급되며, 소정 간격으로 다수의 호스연결부(301a)가 형성됨으로써, 공급관(301)으로 공급되는 세척수는 각 호스연결부(301a)로 배출된다. The supply pipe 301 is supplied with washing water at a predetermined pressure from a washing water supply pump (not shown), and a plurality of hose connection parts 301a are formed at predetermined intervals, so that the washing water supplied to the supply pipe 301 is connected to each hose connection part ( 301a).
상기 로터리조인트(302)는 지지체(302a)와 회전체(302c)를 포함한다. The rotary joint 302 includes a support 302a and a rotating body 302c.
상기 지지체(302a)는 관체로 되되, 일단부에 수나사부(302b)가 형성되고, 타단부는 상기 회전체(302c) 내부에 삽입 설치된다.The support 302a is a tubular body, the male screw portion 302b is formed at one end, and the other end is inserted into the rotating body 302c.
상기 회전체(302c)도 관체로 형성되되, 내부에는 상기 지지체(302a)에 지지되어 공회전이 가능케 하는 베어링수단이 구비되고, 일단부에는 암나사부(302d)가 형성되어, 상기 회전관(20) 일측의 나사부에 나사 결합된다.The rotating body (302c) is also formed of a tubular body, there is provided a bearing means that is supported by the support (302a) to enable idle rotation, one end is formed with a female screw portion (302d), the rotary tube 20 Screwed on one side of the screw.
이때, 상기 회전체(302c) 내부에는 유체의 유동 과정에서 누수를 방지하기 위한 오링(302e)을 구비하는 것이 바람직하다. At this time, it is preferable to include an O-ring 302e in the rotating body 302c to prevent leakage during the flow of the fluid.
상기 연결호스(303)는 양단부에 나사결합부가 형성되어, 일단부는 공급관(301)의 호스연결부(301a)에 나사 결합되고, 타단부는 상기 로터리조인트(302)의 지지체(302a) 일단부에 형성된 수나사부(302b)에 나사 결합된다.The connection hose 303 has a screw coupling portion is formed at both ends, one end is screwed to the hose connecting portion 301a of the supply pipe 301, the other end is formed at one end of the support 302a of the rotary joint 302 It is screwed to the male screw part 302b.
따라서 공급관(301)으로 공급된 세척수는 호스연결부(301a)에 결합된 연결호스(303)와 로터리조인트(302)를 지나 회전관(20)으로 공급된다.Therefore, the washing water supplied to the supply pipe 301 is supplied to the rotary tube 20 through the connection hose 303 and the rotary joint 302 coupled to the hose connecting portion 301a.
이때, 상기 본체프레임(10)에 회전 가능케 설치된 회전관(20)이 축중심을 기준으로 회전하더라도, 회전관(20)과 나사 결합된 로터리조인트(302)의 회전체(302c)는 회전하는 반면, 연결호스(303)의 일단부에 나사 결합된 지지체(302a)의 회전은 억제된다. At this time, even if the rotating tube 20 rotatably installed on the main body frame 10 rotates based on the axis center, while the rotating body 302c of the rotary joint 302 screwed with the rotating tube 20 rotates, The rotation of the support 302a screwed to one end of the connection hose 303 is suppressed.
따라서 세척수의 공급 과정에서 회전관(20)이 회전하더라도, 연결호스(303)의 유동은 억제되기 때문에 꼬임이나 균열 등에 의한 손상을 방지할 수 있게 된다.Therefore, even if the rotary tube 20 is rotated in the process of supplying the washing water, since the flow of the connection hose 303 is suppressed, damage caused by twisting or cracking can be prevented.
상기 분사노즐(40)은 상기 회전관(20)의 타단부에 소정 각도로 설치되어 회전관(20)을 통해 공급되는 세척수를 소정 압력으로 분사한다. The injection nozzle 40 is installed at the other end of the rotary tube 20 at a predetermined angle to spray the washing water supplied through the rotary tube 20 at a predetermined pressure.
상기 분사노즐(40)의 설치 각도는 회전관(20)과 직각을 이루는 것이 바람직하며, 직각의 설치 각도를 위해서 상기 회전관(20)과 분사노즐(40) 사이에는 엘보(401)를 연결하는 것이 바람직하다. It is preferable that the installation angle of the injection nozzle 40 forms a right angle with the rotary tube 20, and connects the elbow 401 between the rotary tube 20 and the injection nozzle 40 for the installation angle of the right angle. It is preferable.
상기 회동수단(50)은 상기 분사노즐(40)을 상기 회전관(20)의 중심축을 기준으로 소정 각도로 왕복 회동시키기 위하여 감속모터(501), 캠(502), 링크로드(503), 승강체(504)를 포함한다. The rotation means 50 is a reduction motor 501, cam 502, link rod 503, elevating in order to reciprocate the injection nozzle 40 at a predetermined angle with respect to the central axis of the rotary tube 20 Sieve 504.
상기 감속모터(501)는 상기 본체프레임(10) 상측에 설치된다.The reduction motor 501 is installed above the main body frame 10.
상기 캠(502)은 상기 감속모터(501)의 구동축에 설치됨으로써, 감속모터(501)의 감속비에 따른 회전 속도로 회전한다.The cam 502 is installed on the drive shaft of the reduction motor 501 to rotate at a rotational speed corresponding to the reduction ratio of the reduction motor 501.
이때, 캠(502)의 회전속도는 30 내지 50rpm으로 회전하는 것이 바람직하다.At this time, the rotation speed of the cam 502 is preferably rotated at 30 to 50rpm.
캠(502)의 회전속도가 30rpm보다 늦으면, 캠(502)에 의해 회동하는 분사노즐(40)의 회동속도가 느려지고, 그로 인해 이동 중인 차량 표면에 세척수를 분사할 때, 세척수의 분사에 따른 세척 시간이 지연됨으로써 세차 시간이 오래 걸리게 된다.When the rotational speed of the cam 502 is later than 30 rpm, the rotational speed of the injection nozzle 40 rotated by the cam 502 becomes slow, and thus, when the washing water is sprayed on the surface of the moving vehicle, the washing according to the spraying of the washing water is performed. The delay results in a longer wash time.
반면, 캠(502)의 회전속도가 50rpm보다 빠르면, 캠(502)에 의해 회동하는 분사노즐(40)의 회동속도가 너무 빨라서 이동 중인 차량 표면에 세척수를 분사할 때, 차량 표면의 오염물이 세척수에 의해 제거가 이루어질 충분한 시간이 제공되지 못하게 되어 세차가 깨끗하게 이루어지지 못하게 된다. On the other hand, when the rotational speed of the cam 502 is faster than 50 rpm, when the spraying speed of the spray nozzle 40 rotated by the cam 502 is too fast to spray the washing water onto the moving vehicle surface, contaminants on the surface of the vehicle are washed out. This does not provide enough time for removal to result in a clean wash.
상기 링크로드(503)는 일단부가 상기 캠(502)의 일면에 편심되게 힌지 결합되어 캠(502)의 회전운동을 직선운동으로 전환한다. One end of the link rod 503 is hinged to one surface of the cam 502 to be eccentric to convert the rotational movement of the cam 502 to linear movement.
상기 승강체(504)는 상단부가 상기 링크로드(503)의 타단부에 회전 가능케 힌지 결합되고, 일측면에 상기 분사노즐(40)의 일단부가 연결 설치되어, 링크로드(503)에 의해 승강하면서 분사노즐(40)을 소정 각도로 왕복 회동시킨다. The lifting body 504 is rotatably coupled to the other end of the upper end of the link rod 503, one end of the injection nozzle 40 is connected to one side, and is elevated by the link rod 503 The injection nozzle 40 is reciprocated at a predetermined angle.
즉, 상기 분사노즐(40)은 상기 본체프레임(10)에서 회전 가능케 세로 방향을 따라 소정 간격으로 설치된 회전관(20)의 일단부에 결합되어 있으므로 다수의 분사노즐(40)이 연결되게 설치된 승강체(504)는 좌우 요동이 억제된다.That is, since the injection nozzle 40 is coupled to one end of the rotary tube 20 installed at predetermined intervals along the longitudinal direction so as to be rotatable in the main body frame 10, the plurality of injection nozzles 40 are installed and connected to each other. The sieve 504 is suppressed from left and right fluctuations.
반면, 승강체(504)의 상단부는 상기 링크로드(503)에 연결되어 있으므로 상기 캠(502)이 회전함에 따라 캠(502)에 힌지 결합된 링크로드(503)의 일단부는 캠(502)과 함께 회전할 때, 링크로드(503)의 타단부에 연결된 승강체(504)는 상하로 승강하게 된다. On the other hand, since the upper end of the lifting body 504 is connected to the link rod 503, one end of the link rod 503 hinged to the cam 502 is rotated with the cam 502 as the cam 502 rotates. When rotating together, the lifting body 504 connected to the other end of the link rod 503 is moved up and down.
따라서 상하로 승강하는 승강체(504)에 연결된 분사노즐(40)은 회전관(20)의 중심축을 기준으로 상하로 왕복 회동하게 된다. Therefore, the injection nozzle 40 connected to the elevating body 504 that moves up and down is reciprocated up and down based on the central axis of the rotary tube 20.
상기 승강체(504)는 상기 링크로드(503)에 의한 승강 시 상기 분사노즐(40)의 왕복 회동이 용이하게 이루어지도록 연결부재(505)를 더 구비할 수 있다. The elevating body 504 may further include a connecting member 505 so that the reciprocating rotation of the injection nozzle 40 is easily performed when the elevating body 504 is elevated by the link rod 503.
상기 연결부재(505)는 직각판 형태로 형성되되, 일측판(505a)은 상기 승강체(504)에 공회전 가능케 힌지핀(505b)으로 힌지 결합되고, 타측판(505c)에는 요입홈(505d)이 형성되어, 상기 요입홈(505d) 내부에 상기 분사노즐(40)의 외측 단부가 삽입된다. The connecting member 505 is formed in a right angle plate shape, one side plate 505a is hinged to the lifting body 504 by a hinge pin 505b so as to be idle, and the other side plate 505c has a recessed groove 505d. Is formed, the outer end of the injection nozzle 40 is inserted into the recess 505d.
따라서 상기 승강체(504)가 상하로 승강할 때, 상기 연결부재(505)의 요입홈(505d)에 삽입된 분사노즐(40)의 일단부가 연결부재(505)에 의해 승강함으로써, 분사노즐(40)의 타단부에 결합된 회전관(20)의 중심축을 기준으로 분사노즐(40)이 상하로 왕복 회동하게 된다.Therefore, when the lifting body 504 is moved up and down, one end of the injection nozzle 40 inserted into the recessed groove 505d of the connecting member 505 is lifted by the connecting member 505, so that the injection nozzle ( The injection nozzle 40 reciprocates up and down on the basis of the central axis of the rotary tube 20 coupled to the other end of 40.
이때, 상기 연결부재(505)는 분사노즐(40)의 회전 각도에 대응하여 상기 힌지핀(505b)의 중심축을 기준으로 회전함으로써, 상기 요입홈(505d) 내부에 삽입된 분사노즐(40)과 요입홈(505d) 간의 마찰에 따른 소음이나 진동 발생이 억제된다.
