Description

Technical Field

[0001] The invention relates to the technical field of a coating substrate conveying device, and in particular to a conveying device for a double-sided coated substrate. Background Art

[0002] Coating refers to a method of applying a paste polymer, a molten polymer or a polymer melt onto paper, cloth, or a plastic film (substrate) to obtain a composite material (film).

[0003] In traditional coating equipment, one device can only coat one side of the substrate. When the other side of the substrate needs to be coated, the equipment needs to be replaced. If one device is used to coat both sides of the substrate, the substrate coated on both sides cannot contact the conveying roller that transports the substrate, making it impossible to transport the substrate stably. This will not only increase production costs, but also reduce production efficiency. Summary of the invention

[0004] In view of the shortcomings of the prior art, an object of the present invention is to provide a conveying device for a double-sided coated substrate, which has the effect of achieving smooth transportation of the double-sided coated substrate without contacting the double-sided coated substrate.

[0005] The above technical effects of the present invention are achieved through the following technical solutions:

[0006] The invention comprises an air supply device arranged on the ground, wherein the output end of the air supply device is connected to an air supply duct, and the end of the air supply duct away from the air supply device is connected to an air wing nozzle; the air wing nozzle comprises a shell, the bottom of the shell is open, the top surface of the shell is provided with a connection port, the end of the air supply duct away from the air supply device is inserted into the shell through the connection port, and the inner top surface of the shell is provided with a sealing member for improving the air tightness of the shell; the bottom opening of the shell is connected with an airfoil plate, the airfoil 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 with two vertical inner side walls opposite to the shell, the inclined section is located at the opening of the bottom of the shell and completely covers the bottom opening of the shell, the lower end of the vertical side wall of the shell near the end with a higher height of the inclined section is provided with a bending section, the height of the bending section is lower than the highest 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 with a height higher than the lower end of the bending section is provided with a plurality of evenly distributed air outlets.

[0007] By adopting the above technical scheme, when in use, the double-sided coated substrate is placed horizontally under the air wing nozzle, and a gap is left between the substrate and the air wing nozzle, and then the air supply device is started. The wind blown out by the air supply device enters the shell of the air wing nozzle through the air supply duct. After entering the shell, the gas will be discharged from the shell from the air outlet and evenly sprayed out 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. Moreover, due to the traction of the airflow, the double-sided coated substrate can be smoothly transported without contacting the substrate.

[0008] 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 distributed around the connecting port and are tightly attached to the outer wall of the air supply duct at the connecting port.

[0009] By adopting the above technical solution, the sealing ring can fill the gap between the air supply duct and the edge of the connecting port, thereby preventing the gas in the shell from being discharged from the shell through the connecting port, and ensuring that the air wing nozzle can work normally.

[0010] 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.

[0011] 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.

[0012] In a preferred example, the present invention can be further configured as follows: a fin is connected to the outer wall of the vertical side wall of the shell near the lower end of the inclined section, and the fin 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 lower end of the inclined section, the lower end of the drainage section is connected to the lower end 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.

[0013] 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; and because the air inlet hole is provided, the air above the fin plate can enter between the fin plate and the double-sided coated substrate through the air inlet hole, so that the forward-flowing airflow is stabilized, ensuring that the airflow can smoothly transport the double-sided coated substrate.

[0014] In a preferred example, the present invention can be further configured as follows: a bracket 1 is connected to the drainage section, and an end of the bracket 1 away from the drainage section is connected to the vertical side wall connecting the shell and the connecting section.

[0015] By adopting the above technical solution, the bracket 1 can improve the stability of the fin plate and reduce the possibility of the fin plate shaking, thereby reducing the adverse effect of the fin plate shaking on the airflow transport substrate.

[0016] In a preferred example, the present invention can be further configured as follows: the air supply device is a variable frequency air supply fan.

[0017] By adopting the above technical solution, it is convenient for the staff to adjust the air output of the air supply device to cope with different working conditions.

[0018] In a preferred example, the present invention can be further configured as follows: a bracket 2 is connected to the air supply duct, one end of the bracket 2 is connected to the air supply duct, and the other end is against the ground.

[0019] By adopting the above technical solution, the second bracket plays a role in supporting the air supply duct, which can improve the stability of the air supply duct.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] 1. When in use, the air blown by the air supply device enters the shell of the air wing nozzle through the air supply duct, and the gas in the shell is discharged from the shell through the air outlet and sprayed out from the gap between the bending section and the inclined section. Due to the wall attachment effect of the airflow, the airflow will move 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 airfoil, and the substrate is in a suspended state, which avoids scratches on the substrate. In addition, due to the traction of the airflow, the double-sided coated substrate can be transported smoothly;

[0022] 2. After the airflow leaves the airfoil, it can continue to flow forward smoothly along the fin, thereby continuing to smoothly transport the double-sided coated substrate. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The bottom opening of the shell 4 is connected with an airfoil plate 6, which includes two vertical sections 61 and an inclined section 62 located between the two vertical sections 61. The two vertical sections 61 and the inclined section 62 are integrally formed. The two vertical sections 61 are respectively attached to and connected to the two opposite vertical inner walls of the shell 4. The inclined section 62 is located at the bottom opening of the shell 4 and completely covers the bottom opening of the shell 4. A bending section 7 is provided at the lower end of the vertical side wall of the shell 4 near the higher end of the inclined section 62. The height of the bending section 7 is lower than the highest point of the inclined section 62. The bending section 7 is bent in the direction close to the inclined section 62 and a gap is left between the end of the bending section 7 and the inclined section 62. A portion of the inclined section 62 that is higher than the lower end of the bending section 7 is provided with a number of evenly distributed air outlets 8.

[0037] A wind leveling plate 9 is connected between the two vertical sections 1 61. The wind leveling plate 9 includes two vertical sections 2 91 and a horizontal section 92 located between the two vertical sections 2 91. The two vertical sections 2 91 and the horizontal section 92 are integrally formed. The two vertical sections 2 91 are respectively fitted with the two vertical sections 1 61. In order to ensure the stability of the connection between the wind leveling plate 9 and the airfoil plate 6 and the shell 4, the vertical side wall of the shell 4 and the vertical section 1 61, the vertical section 1 61 and the vertical section 2 91 are connected by a plurality of rivets. A plurality of evenly distributed wind leveling holes 10 are provided on the horizontal section 92.

[0038] The outer wall of the vertical side wall of the shell 4 near the lower end of the inclined section 62 is connected with a fin plate 11, and the fin plate 11 includes a vertically arranged connecting section 111 and an inclinedly arranged drainage section 112. The connecting section 111 is fitted with the outer wall of the vertical side wall of the shell 4 near the lower end of the inclined section 62. In order to ensure the stability of the connection between the fin plate 11 and the shell 4, the connecting section 111, the vertical section 161 and the vertical side wall of the shell 4 near the lower end of the inclined section 62 are connected by a plurality of rivets.

[0041] Working principle of the present invention:

[0042] When in use, the double-sided coated substrate is placed horizontally below the air wing nozzle 3, leaving a gap between the substrate and the air wing nozzle 3, and then the air supply device 1 is started, and the air blown by the air supply device 1 enters the shell 4 of the air wing nozzle 3 through the air supply duct 2. After entering the shell 4, the gas first passes through the air uniforming plate 9, and then is discharged from the shell 4 steadily and evenly from the air outlet 8, and is evenly sprayed out from the gap between the bending section 7 and the inclined section 62;

[0043] Due to the wall attachment effect of the airflow, the airflow will move along the outer wall of the inclined section 62. As the space between the substrate and the inclined section 62 gradually narrows, negative pressure is formed, which generates suction on the substrate. However, due to the existence of the airflow, the substrate will not contact the airfoil 6, and the substrate is in a suspended state, thereby avoiding scratches on the substrate. In addition, due to the traction of the airflow, the double-sided coated substrate 14 can be transported.

[0044] In addition, since the air inlet 15 is provided on the fin 11, the air above the fin 11 can enter between the fin 11 and the double-sided coated substrate 14 through the air inlet 15, stabilizing the forward airflow and ensuring that the airflow can smoothly transport the double-sided coated substrate 14.

[0045] In summary, the conveying device for a double-sided coated substrate provided in this embodiment can realize smooth transportation of the double-sided coated substrate 14 without contacting the substrate.

[0046] 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.
