Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to an air flotation roller shielding sheet structure. Background Technology

[0002] In the process of simultaneous double-sided coating, the foil needs to be dried in an oven after coating. During the drying conveyor belt process, rollers need to be arranged at certain intervals to provide support for the foil to avoid foil vibration. Traditional conveyor rollers are contact support rollers, which come into direct contact with the foil. Since the surface paste of the double-sided coated foil is not dry, the paste will stick to the roller surface, damaging the foil coating. Therefore, air-bearing rollers are often used to provide non-contact support. However, the air-bearing rollers in the existing technology have a fixed air outlet angle, which severely limits the application range of the air-bearing rollers. Moreover, due to the fixed air outlet angle, the air pressure on the air-bearing roller is higher in the middle and lower at both sides, which will also cause the two edges of the foil to float at different heights, making the foil prone to vibration. This not only damages the paste on the foil, but in severe cases, it can also cause belt breakage, affecting the quality of the foil coating.

[0003] Therefore, there is a need to provide an air-float roller shielding sheet structure to solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an air flotation roller shielding plate structure, which can dynamically adjust the air flotation support range of the roller surface and increase the edge pressure, thereby improving the applicability and air flotation performance of the air flotation roller.

The second shielding plate is provided with the first shielding plate and the third shielding plate at both ends.

[0012] As a further improvement to the above technical solution, the fastening screw includes a fixing screw, a first limiting screw and a second limiting screw.

The first limiting screw passes through the waist hole and the second or third through hole and is connected to the air flotation roller.

[0016] The beneficial effects of this utility model are:

[0025] Reference Figure 1 , Figure 2An air flotation roller shielding structure includes an air flotation roller 1 and multiple shielding plates 2. The multiple shielding plates 2 are installed on the outside of the air flotation roller 1. Each of the multiple shielding plates 2 includes a first shielding plate 3, a second shielding plate 4, and a third shielding plate 5, which are stacked sequentially from the inside to the outside. The two ends of the second shielding plate 4 are provided with the first shielding plate 3 and the third shielding plate 5. This structure not only enhances the integrity of shielding the air outlet on the air flotation roller 1, but also allows for better control of the spray on the air flotation roller. The outflow has a certain guiding and buffering effect; and the first shielding plate 3 and the third shielding plate 5 both rotate around the center of the air float roller 1. The dynamic shielding method has higher flexibility and adaptability. The shielding angle and range of the shielding plate 2 can be adjusted according to actual needs to guide the gas blown out of the air float roller 1 to the edge of the foil, increase the pressure at the edge of the air float roller 1, reduce the air pressure deviation on the air float roller 1, improve the stability of foil conveying, and increase the air float height at the edge of the foil by blocking and changing the direction of the gas to prevent the foil from scraping the roller.

[0026] Reference Figure 2 In this embodiment of the present invention, the first shielding plate 3, the second shielding plate 4, and the third shielding plate 5 are all configured with a U-shaped groove structure. The air-floating roller 1 is inserted into the U-shaped groove to achieve stable installation and fixation of the shielding plate 2. The first shielding plate 3, the second shielding plate 4, and the third shielding plate 5 each include an arc-shaped baffle 21 and a connecting plate 22. The arc-shaped baffle 21 fits into the air-floating roller 1 to ensure that the first shielding plate 3 can be tightly attached to the surface of the air-floating roller 1. The first shielding plate 3 and the third shielding plate 5 are respectively tightly connected to the second shielding plate 4, thereby effectively blocking the irregular discharge of gas. The connecting plate 22 is provided at both ends of the arc-shaped baffle 21, and the connecting plate 22 can be fixed to the end of the air-floating roller 1 by bolts, nuts, or other fasteners to ensure the stability of the shielding plate 2 and prevent the shielding plate 2 from loosening or falling off when the air-floating roller 1 is working.

[0027] Reference Figure 3In this embodiment of the present invention, the end of the air-bearing roller 1 is provided with a plurality of fastening screws 11. The plurality of fastening screws 11 pass through the connecting plate 22 of the shielding plate 2 and are connected to the air-bearing roller 1 to achieve a stable connection between the shielding plate 2 and the air-bearing roller 1. The connecting plate 22 of the first shielding plate 3 and the third shielding plate 5 is provided with a waist hole 221. The connecting plate 22 of the second shielding plate 4 is provided with a first through hole 222, a second through hole 223 and a third through hole 224. The second through hole 223 and the third through hole 224 are symmetrically arranged with the first through hole 222 as the center, so that the first shielding plate 3 or the third shielding plate 5 connected to both ends of the second shielding plate 4 are also symmetrically installed to ensure that the air pressure blown out from both ends of the air-bearing roller 1 is consistent, thereby ensuring the stability of the foil conveying. The fastening screws 11 include a fixing screw 111, a first limiting screw 112 and a second limiting screw 113. The limiting screw 113, the fixing screw 111, passes through the first through hole 222 and connects to the air-float roller 1 to achieve initial fixation of the second shielding plate 4; the first limiting screw 112 passes through the waist hole 221 and the second through hole 223 or the third through hole 224 and connects to the air-float roller 1 to firmly connect the second shielding plate 4 to the air-float roller 1, and at the same time, to initially limit and fix the first shielding plate 3 and the third shielding plate 5; the second limiting screw 113 passes through the waist hole 211 and connects to the air-float roller 1 to further fix the first shielding plate 3 and the third shielding plate 5, ensuring their stability during operation, and at the same time, allowing the first shielding plate 3 and the third shielding plate 5 to be easily adjusted in angle and position through the design of the waist hole 221, so as to dynamically adjust the air outlet area and gas flow direction of the air-float roller, and improve the suspension effect and edge pressure of the foil.

[0028] Reference Figure 4 In an embodiment of this utility model, the arc length of the third shielding plate 5 is greater than that of the first shielding plate 1, so that a reversing channel 6 is formed between the third shielding plate 5 and the air flotation roller 1. The surface of the air flotation roller 1 is arrayed with several air outlet holes, so that the gas inside the air flotation roller 1 can be discharged uniformly in 360 degrees. The airflow in the direction of the first shielding plate 3 and the third shielding plate 5 is blocked, so that the airflow changes direction from the reversing channel 6 and blows air towards the edge of the foil, thereby increasing the pressure and air flotation height of the foil edge, so as to avoid the foil scraping the roller, reduce the friction and wear between the foil and the roller surface, and extend the service life of the equipment.
