Technical Field

[0001] The utility model relates to the technical field of ear material conveying, in particular to an adjustable aluminum nozzle. Background Art

[0002] In existing industrial production, the spraying of glass fiber bait is widely used, but the existing nozzle design has certain limitations when processing glass fiber bait of different specifications. Generally, the design of the nozzle needs to be adjusted according to the specific air flow pressure to ensure that the glass fiber bait can be stably transported.

[0003] In addition, the existing nozzles often generate a lot of noise when the high-pressure airflow flows out, and the spraying of the glass fiber bait may also be accompanied by corresponding noise. These noises not only affect the comfort of the production environment, but may also have a negative impact on the health of the workers.

[0004] In addition, when the traditional nozzle design sucks in the glass fiber bait, due to design limitations, the diameter of the nozzle suction port is relatively large, resulting in insufficient air pressure difference to effectively improve the suction efficiency of the airflow and the glass fiber bait.

[0030] Embodiment 1:

[0031] like Figures 1 to 6 As shown, an adjustable aluminum nozzle includes a nozzle 101, a suction nozzle 102 is threadedly connected to the nozzle 101, a first protective ring 111 and a left protective ring 110 are threadedly connected to the nozzle 101, a second protective ring 112 is threadedly connected to the first protective ring 111, a third protective ring 113 is threadedly connected to the second protective ring 112, an outer wall diameter of the third protective ring 113 is equal to an inner wall diameter of the second protective ring 112, and an outer wall diameter of the second protective ring 112 is equal to an inner wall diameter of the first protective ring 111.

[0032] The nozzle 101 is provided with a conical inner cavity, the suction nozzle 102 is provided with an arc-shaped opening, and an air cavity is provided between the nozzle 101 and the suction nozzle 102 .

[0033] Specifically, when conveying the glass fiber ear material, one end of the ear material is inserted into the nozzle 101, and then by introducing external airflow, the airflow enters the nozzle 101 through the air cavity between the nozzle 101 and the suction nozzle 102, and is blocked by the first protective ring 111, the second protective ring 112 and the third protective ring 113, so that the airflow flows in the opposite direction, so that the airflow flows along the inner cavity of the nozzle 101 in the direction away from the suction nozzle 102, thereby driving the inserted glass fiber ear material to move, thereby realizing the conveyance of the ear material.

[0034] like Figure 3As shown in the figure, the inner wall of the nozzle 101 is conical, and the diameter of the end close to the suction nozzle 102 is smaller than the diameter of the end away from the suction nozzle 102, and an annular cavity is formed where the suction nozzle 102 contacts the nozzle 101, and the end of the nozzle 101 with a small opening has no direct contact with the suction nozzle 102, so that after the airflow enters the suction nozzle 102, it passes through the annular cavity, flows to the surroundings of the nozzle 101, and flows to the suction nozzle 102 along the conical structure of the nozzle 101, and then passes through the conical structure formed by the first guard ring 111, the second guard ring 112 and the third guard ring 113 on the suction nozzle 102. The end of the conical structure close to the nozzle 101 has a large diameter, and the end away from the nozzle 101 has a small diameter, so that the airflow passes through the obstruction of the first guard ring 111, the second guard ring 112 and the third guard ring 113. The airflow is blocked and its direction is bent, thereby changing its direction. That is, after the airflow enters the air cavity between the nozzle 101 and the suction nozzle 102, the airflow flows along the conical outer wall of the nozzle 101 in the direction of the suction nozzle 102, and enters the inner cavity of the suction nozzle 102 through the gap between the opening at the right end of the suction nozzle 102 and the right end of the nozzle 101, and then the airflow contacts the first protective ring 111, the second protective ring 112 and the third protective ring 113. The three protective rings continuously block the airflow, thereby changing its flow direction and making it flow toward the glass fiber ear material. Furthermore, in the inner cavity of the nozzle 101 and the suction nozzle 102, the airflow direction is bent again through the interaction of the surrounding airflows, so that the airflow drives the glass fiber ear material to move along the direction of the nozzle 101 and away from the suction nozzle 102, thereby realizing the transportation of the ear material.

[0035] like Figures 1 to 3 As shown, a connecting pipe 109 is fixedly mounted on the suction nozzle 102 , a first end of an input pipe 104 is fixedly mounted on the connecting pipe 109 , and a pressure regulating valve 105 is fixedly mounted on the second end of the input pipe 104 .

[0036] Specifically, the air source is sucked in through the inlet on the left side of the pressure regulating valve 105, and the pressure is adjusted so that the high-pressure air source is output from the outlet on the right side of the pressure regulating valve 105, and is input into the air cavity between the nozzle 101 and the suction nozzle 102 through the input pipe 104 and the connecting pipe 109. The glass fiber ear material is driven to move by the high-pressure airflow, and the pressure regulating valve 105 can be adjusted according to the specifications of the glass fiber ear material to form air sources with different pressures, thereby adapting to the stable transportation of various ear materials.

[0037] like Figure 3 and Figure 4 As shown, the first protective ring 111 , the second protective ring 112 , the third protective ring 113 and the left protective ring 110 are made of ceramic materials, and the inner wall diameter of the third protective ring 113 is much smaller than the inner wall diameter of the nozzle 101 near the suction nozzle 102 .

[0038] The aluminum nozzle is protected and supported by providing a first protective ring 111, a second protective ring 112, a third protective ring 113 and a left protective ring 110 to prevent the glass fiber ear material from contacting the inner wall of the aluminum nozzle when being output at a high speed, thereby preventing friction between the nozzle and the nozzle, thereby causing wear, and ultimately extending the service life of the aluminum nozzle.

[0039] By using ceramic materials to make the left protective ring 110, the first protective ring 111, the second protective ring 112 and the third protective ring 113, the wear resistance of the protective rings is improved to avoid damage caused by long-term contact with the glass fiber ear material.

[0040] The inner wall diameters of the first protective ring 111, the second protective ring 112 and the third protective ring 113 are gradually reduced to form a conical baffle ring, and the feed port of the suction nozzle 102 is reduced. Therefore, when the pressure regulating valve 105 delivers an air source with the same air pressure, the air source passes through the gap between the nozzle 101 and the suction nozzle 102, and after being blocked by the third protective ring 113 and changed direction, the flow of the air flow will form an air pressure difference, thereby driving the air flow outside the third protective ring 113 to enter the third protective ring 113, and drive the ear material to move together with the air source of the pressure regulating valve 105. When the diameter of the feed port of the third protective ring 113 becomes smaller, the suction force formed in the suction nozzle 102 is greater, thereby accelerating the delivery of the glass fiber ear material.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, the nozzle 101 is fixedly connected with an output tube 103 , the output tube 103 is slidably connected with a perforated plate 107 , and the perforated plate 107 is fixedly connected with a suction cotton 106 .

[0042] The perforated plate 107 is frictionally connected with a restraining hoop 108 , and the suction cotton 106 and the perforated plate 107 are fixed on the output pipe 103 through the restraining hoop 108 .

[0043] Specifically, the suction cotton 106 and the perforated plate 107 are clamped by a clamping hoop 108 to be fixed on the outlet of the output pipe 103. The suction cotton 106 is provided with a plurality of through holes. The perforated plate 107 is a sound-absorbing material. The outlet of the output pipe 103 is silenced by the cooperation of the suction cotton 106 and the perforated plate 107 to avoid noise pollution.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
