Description

Technical Field

[0001] The invention relates to the technical field of air-floating oven nozzles, and in particular to an air-wing nozzle for suspending and conveying low-tension materials. Background Art

[0002] The nozzle is a key component of the air flotation oven, which is usually connected to the plug at the outlet end of the air collecting chamber and used in conjunction with it. The traditional nozzle is mainly an impact type nozzle, which supports the substrate through the impact airflow blown out by the nozzle, and realizes the drying and supporting functions at the same time. However, this type of nozzle requires the substrate to have a high tension. For some materials that can only be conveyed at low tension, this type of nozzle usually cannot meet the requirements. Summary of the invention

[0003] In view of the deficiencies in the prior art, an object of the present invention is to provide an airfoil nozzle for suspended conveying of low-tension materials, which has the effect of achieving suspended conveying of low-tension materials.

[0004] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0005] A pneumatic wing nozzle for suspended conveying of low-tension materials, comprising a shell, the top of the shell is open, the bottom surface of the shell is provided with a connection port for inserting a plug of an air collecting chamber, and the inner bottom surface of the shell is provided with a sealing member for improving the air tightness of the shell; an wing plate is connected to the top opening of the shell, the wing plate comprises two vertical sections one and an inclined section located between the two vertical sections one, the two vertical sections one are respectively attached to and connected to two vertical inner side walls opposite to the shell, the inclined section is located at the opening at the top of the shell and completely covers the top opening of the shell, a bending section is provided at the top end of the vertical side wall of the shell near the lower end of the inclined section, the height of the bending section is higher than the lowest point of the inclined section, the bending section is bent in a direction close to the inclined section and a gap is left between the end of the bending section and the inclined section, and a portion of the inclined section whose height is lower than the top of the bending section is provided with a number of evenly distributed air outlets.

[0006] By adopting the above technical scheme, when in use, the substrate is placed above the wing plate and a gap is ensured between the substrate and the inclined section, the plug of the air collecting chamber is inserted into the connecting port, and the seal can seal the contact between the plug of the air collecting chamber and the edge of the connecting port, thereby improving the air tightness of the shell. The plug of the air collecting chamber blows out gas, and after the gas enters the shell, it can be discharged from the shell from the air outlet and evenly sprayed from the gap between the bending section and the inclined section. Due to the wall attachment effect of the airflow, the airflow will advance along the outer wall of the inclined section. As the space between the substrate and the inclined section gradually narrows, negative pressure is formed, which generates suction on the substrate. However, due to the existence of airflow, the substrate will not contact the wing plate, and the substrate is in a suspended state, which avoids scratches on the substrate, and due to the traction of the airflow, the suspended operation of the low-tension substrate can be achieved.

[0007] In a preferred example, the present invention can be further configured as follows: the sealing member includes a sealing groove plate and a sealing ring arranged in the sealing groove plate, and the sealing groove plate and the sealing ring are both distributed around the connecting port.

[0008] By adopting the above technical solution, when in use, the plug of the gas collecting chamber is inserted into the shell from the connecting port, and the sealing ring surrounds the plug of the gas collecting chamber and fits with the plug of the gas collecting chamber, thereby filling the gap between the plug of the gas collecting chamber and the edge of the connecting port, thereby improving the sealing effect.

[0009] In a preferred example, the present invention can be further configured as follows: a wind uniformity plate is connected between the two vertical segments one, the wind uniformity plate includes two vertical segments two and a horizontal segment located between the two vertical segments two, the two vertical segments two are respectively fitted with the two vertical segments one, and a number of evenly distributed wind uniformity holes are opened on the horizontal segment.

[0010] By adopting the above technical solution, the gas in the shell first passes through the air uniformity plate from the air uniformity hole, and then can be discharged from the shell from the air outlet hole. The air uniformity plate can improve the stability and uniformity of the gas flow, thereby making the airflow more stable when blowing out of the shell.

[0011] In a preferred example, the present invention can be further configured as follows: the vertical side wall, vertical section 1 and vertical section 2 of the shell are connected by rivets.

[0012] By adopting the above technical solution, the riveted connection method is firm and reliable, and can avoid the adverse effects of deformation on the shell, the airfoil plate and the wind uniforming plate caused by the traditional welding connection method.

[0013] In a preferred example, the present invention can be further configured as follows: a fin plate is connected to the outer wall of the vertical side wall of the shell near the higher end of the inclined section, and the fin plate includes a vertically arranged connecting section and an inclined drainage section, the connecting section is fitted with the outer wall of the vertical side wall of the shell near the higher end of the inclined section, the higher end of the drainage section is connected to the top of the connecting section and the drainage section extends in a direction away from the inclined section, and a plurality of air inlet holes are also provided on the drainage section.

[0014] By adopting the above technical solution, after the airflow leaves the airfoil, it can continue to flow forward smoothly along the fin plate, so that the substrate can continue to be transported. Moreover, since the air inlet holes are provided, the air under the fin plate can pass through the air inlet holes into between the fin plate and the substrate, so that the forward-flowing airflow is stabilized, ensuring that the airflow can smoothly transport the substrate.

[0015] In a preferred example, the present invention can be further configured as follows: the vertical side wall, vertical section 1 and connecting section of the shell are connected by rivets.

[0016] By adopting the above technical solution, the riveted connection method is firm and reliable, and can avoid the adverse effects of deformation of the shell and the fin plate caused by the traditional welding connection method.

[0017] In a preferred example, the present invention can be further configured as follows: a bracket is connected to the bottom surface of the drainage section, and one end of the bracket away from the drainage section is connected to the vertical side wall connecting the shell and the connecting section.

[0018] By adopting the above technical solution, the bracket can support the fin plate, thereby improving the stability of the fin plate.

[0019] In summary, the present invention includes the following beneficial technical effects:

[0020] After the gas is blown out of the air collecting chamber, the gas first passes through the wind uniforming plate, and then is discharged from the shell from the air outlet. Next, the gas is blown out from the gap between the bending section and the airfoil plate, and flows along the outer wall of the airfoil plate to the fin plate. During the movement of the airflow, negative pressure will be formed and suction will be generated on the substrate. However, due to the existence of the airflow, the substrate will not contact the airfoil plate. Therefore, the airflow can generate traction on the substrate, thereby realizing the suspended transportation of the low-tension substrate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] Example:

[0029] Reference Figure 1-5 , an air wing nozzle for suspended conveying of low-tension materials disclosed in the present invention, comprises a shell 1, the top of the shell 1 is open, a connection port for inserting a plug of an air collecting chamber 2 is provided at the center of the bottom surface of the shell 1, and a sealing member 3 for improving the air tightness of the shell 1 is provided on the inner bottom surface of the shell 1.

[0030] The seal 3 includes a sealing groove plate 31 and a sealing ring 32. The sealing groove plate 31 is welded to the inner wall of the shell 1 and is distributed around the connection port. The sealing ring 32 is bonded inside the sealing groove plate 31 and is distributed around the connection port following the sealing groove plate 31.

[0031] The top opening of the shell 1 is connected with an airfoil plate 4, which includes two vertical sections 41 and an inclined section 42 located between the two vertical sections 41. The two vertical sections 41 and the inclined section 42 are integrally formed. The two vertical sections 41 are respectively attached to and connected with the two opposite vertical inner walls of the shell 1. The inclined section 42 is located at the opening of the top of the shell 1 and completely covers the top opening of the shell 1. A bending section 5 is provided at the top of the vertical side wall of the shell 1 near the lower end of the inclined section 42. The height of the bending section 5 is higher than the lowest point of the inclined section 42. The bending section 5 is bent in the direction close to the inclined section 42 and a gap is left between the end of the bending section 5 and the inclined section 42. A portion of the inclined section 42 whose height is lower than the top of the bending section 5 is provided with a number of evenly distributed air outlets 6.

[0032] A wind leveling plate 7 is connected between the two vertical sections 1 41. The wind leveling plate 7 includes two vertical sections 2 71 and a horizontal section 72 located between the two vertical sections 2 71. The two vertical sections 2 71 and the horizontal section 72 are integrally formed. The two vertical sections 2 71 are respectively fitted with the two vertical sections 1 41. In order to ensure the stability of the connection between the wind leveling plate 7, the airfoil plate 4 and the shell 1, the vertical side wall of the shell 1 fitted with the vertical section 1 41, the vertical section 1 41 and the vertical section 2 71 are connected by a plurality of rivets. A plurality of evenly distributed wind leveling holes 8 are provided on the horizontal section 72.

[0033] The outer wall of the vertical side wall of the shell 1 near the higher end of the inclined section 42 is connected with a fin plate 9, and the fin plate 9 includes a vertically arranged connecting section 91 and an inclinedly arranged drainage section 92. The connecting section 91 is fitted with the outer wall of the vertical side wall of the shell 1 near the higher end of the inclined section 42. In order to ensure the stability of the connection between the fin plate 9 and the shell 1, the connecting section 91, the vertical section 141 and the vertical side wall of the shell 1 near the higher end of the inclined section 42 are connected by a plurality of rivets. The higher end of the drainage section 92 is integrally formed with the top end of the connecting section 91 and the drainage section 92 extends in a direction away from the inclined section 42. The drainage section 92 is also provided with a plurality of air inlet holes 13.

[0034] A bracket 10 is welded to the bottom surface of the drainage section 92, and a welding nut 11 is welded to the bottom of the inner wall of the vertical side wall connecting the shell 1 and the connecting section 91. The end of the bracket 10 away from the drainage section 92 is connected to the shell 1 through the cooperation of the welding nut 11 and the screw, and a waist-shaped hole (not shown in the figure) is opened at the end of the bracket 10 away from the drainage section 92. The length direction of the waist-shaped hole is the vertical direction, and the screw passes through the waist-shaped hole and is connected to the welding nut 11. The bracket 10 can support the fin plate 9, thereby improving the stability of the fin plate 9; the setting of the waist-shaped hole enables the staff to adjust the height of the end of the bracket 10 away from the drainage section 92, so as to adjust the parallelism of the installation of the fin plate 9, so as to facilitate the fin plate 9 to play a drainage role.

[0035] The working principle of the present invention is:

[0036] When in use, the low-tension substrate 12 is placed above the airfoil plate 4, and a gap is left between the substrate 12 and the airfoil plate 4; the plug of the gas collecting chamber 2 is inserted into the connecting port, and the sealing ring 32 is tightly fitted with the outer wall of the plug of the gas collecting chamber 2, thereby preventing the gas ejected from the gas collecting chamber 2 from being discharged from the connecting port to the outside of the shell 1, thereby improving the air tightness of the shell 1;

[0037] After the gas ejected from the air collecting chamber 2 enters the shell 1, it passes through the uniform air hole 8 into the space between the uniform air plate 7 and the wing plate 4, and then passes through the air outlet 6 to be discharged from the shell 1, and is ejected evenly from the gap between the bending section 5 and the inclined section 42. Due to the wall attachment effect of the airflow, the airflow will move along the outer wall of the inclined section 42. As the space between the substrate 12 and the inclined section 42 gradually narrows, negative pressure is formed, which generates suction on the substrate 12. However, due to the existence of the airflow, the substrate 12 will not contact the wing plate 4, and the substrate 12 is in a suspended state, which prevents the substrate 12 from being scratched. In addition, due to the traction of the airflow, the suspended transportation of the low-tension substrate 12 can be achieved.

[0038] In addition, since the fin plate 9 is provided with an air inlet 13 , the air below the fin plate 9 can pass through the air inlet 13 into between the fin plate 9 and the substrate 12 , stabilizing the forward airflow, so that the airflow can smoothly transport the substrate 12 .

[0039] In summary, the air wing nozzle for suspended conveying of low-tension materials proposed in this embodiment has the advantage of being able to achieve suspended conveying of low-tension materials.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
