Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a roller installation structure. Background Art

[0002] The rollers in existing coating equipment typically use ordinary ball bearings for support and rotation. Due to the high friction of ball bearings, when the wrap angle is small, the contact area between the roller and the substrate is small, and the total friction generated between the contact surfaces is reduced, affecting the transmission torque and causing the roller to slip. Currently, air bearings are used in place of ball bearings on the market. Air bearings reduce the rotational resistance of the roller itself and can ensure that they can rotate synchronously with the movement of the substrate when contacting the substrate at a small wrap angle without slipping. Due to the low friction of air bearings, the substrate will generate lateral force during transmission, driving the air bearing roller to move left and right, affecting the transmission effect and the coating quality of the substrate surface.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0033] Reference Figures 1 to 4 A roller installation structure includes a roller 7, a first shaft end fixing component 1 installed at one end of the roller 7, and a second shaft end fixing component 2 installed at the other end of the roller 7;

[0034] The first shaft end fixing assembly 1 is mounted on the first fixing member 71; the second shaft end fixing assembly 2 is mounted on the second fixing member 72; the relative positions between the first fixing member 71 and the second fixing member 72 are fixed;

[0035] The first shaft end fixing assembly 1 includes a first air-floating sleeve 11 sleeved on one end of the roller 7 and a first roller shaft fixing member 12; the first air-floating sleeve 11 is fixed to the first fixing member 71 and is rotatably connected to one end of the roller 7, and the first roller shaft fixing member 12 is fixedly connected to one end of the roller 7, and the first roller shaft fixing member 12 is arranged in contact with the first air-floating sleeve 11;

[0036] Among them, the second shaft end fixing assembly 2 includes a second air-floating sleeve 21 and a second roller shaft fixing piece 22 which are sleeved on the other end of the roller 7; the second air-floating sleeve 21 is fixed on the second fixing piece 72 and is rotatably connected to the other end of the roller 7, the second roller shaft fixing piece 22 is fixedly connected to the other end of the roller 7, and the second roller shaft fixing piece 22 is arranged in contact with the second air-floating sleeve 21.

[0037] In this embodiment, the relative positions of the first fixing member 71 and the second fixing member 72 are fixed, so the relative positions of the first air-floating sleeve 11 and the second air-floating sleeve 21 fixed thereon are also fixed. The first roller shaft fixing member 12 and the second roller shaft fixing member 22 are respectively used for fixing at both ends of the roller 7. The first roller shaft fixing member 12 always remains in contact with the first air-floating sleeve 11, and the second roller shaft fixing member 22 always remains in contact with the second air-floating sleeve 21. The first air-floating sleeve 11 and the second air-floating sleeve 21 are limited to prevent the roller 7 from moving left and right laterally.

[0038] It can be understood that when the roller 7 is used, it rotates and moves by relying on the friction force of the contact surface with the substrate. When the roller 7 rotates, it drives the first roller shaft fixing part 12 to rotate relative to the first air-floating sleeve 11 and the second roller shaft fixing part 22 to rotate relative to the second air-floating sleeve 21.

[0039] Furthermore, the first shaft end fixing assembly 1 further includes a vertical shaft adjustment block 13 provided below the first air-floating sleeve 11;

[0040] The second shaft end fixing assembly 2 further includes a horizontal shaft adjustment block 23 provided on one side of the second air-floating sleeve 21;

[0041] The vertical axis adjustment block 13 is used to adjust the horizontal position of the roller end located in the first shaft end fixing assembly 1 relative to the roller end located in the second shaft end fixing assembly 2 to ensure the coaxiality of the two ends of the roller 7;

[0042] The horizontal axis adjustment block 23 is used to adjust the coaxiality of the second air-floating sleeve 21 relative to the first air-floating sleeve 11 to ensure that the roller 7, the first air-floating sleeve 11, the second air-floating sleeve 21, the first roller shaft fixing member 12 and the second roller shaft fixing member 22 are in the same straight line, thereby avoiding the first air-floating sleeve 11, the second air-floating sleeve 21 and the two ends of the roller 7 from getting stuck.

[0043] Specifically, the first air-floating sleeve 11 faces away from the end connected to the first roller shaft fixing member 12, and a first through-slot 111 is provided below the first roller shaft fixing member 12; the vertical axis adjustment block 13 is fixed on the first fixing member 71, a portion of the vertical axis adjustment block 13 extends into the first through-slot 111, one side of the vertical axis adjustment block 13 abuts against the outer wall below the first air-floating sleeve 11, and the vertical axis adjustment block 13 includes at least two horizontal adjustment screws 131, each of which passes through the vertical axis adjustment block 13 and has one end abutted against the outer wall below the first air-floating sleeve 11; the first air-floating sleeve 11 can be adjusted by turning the horizontal adjustment screw 131;

[0044] The second air-floating sleeve 21 is facing away from the end connected to the second roller shaft fixing piece 22, and a second through-slot 211 is provided on the left or right side of the second roller shaft fixing piece 22; the horizontal axis adjustment block 23 is fixed on the second fixing piece 72, and a portion of the horizontal axis adjustment block 23 extends into the second through-slot 211, and one side of the horizontal axis adjustment block 23 is against the side wall of the second air-floating sleeve 21, and the horizontal axis adjustment block 23 includes at least two spacing adjustment screws 231, and the spacing adjustment screw 231 passes through the horizontal axis adjustment block 23 and one end is against the lower outer wall of the second air-floating sleeve 21; by turning the spacing adjustment screw 231, the second air-floating sleeve 21 can be adjusted.

[0045] The first air-floating sleeve 11 and the second air-floating sleeve 21 are provided with a plurality of air pipe joints 4. Taking the first air-floating sleeve 11 as an example, air enters the first air-floating sleeve 11 through the air pipe joint 4, forming an air film on the end surface of the first air-floating sleeve 11 and the roller 7. Under the support of the air film, the roller 7 is in a suspended state.

[0046] In the prior art, only one air pipe joint is designed in the first air floating sleeve 11 and the second air floating sleeve 21, resulting in a small air intake volume and low air film stiffness, which reduces the stability and reliability of the bearing. In this embodiment, multiple air pipe joints 4 are provided to increase the air intake volume and ensure the stability of the air film.

[0047] Specifically, the plurality of air pipe joints 4 are distributed on the first air floating sleeve 11 and the second air floating sleeve 21 at intervals along the axial direction of the roller 7 to enhance the uniformity of the formed air film.

[0048] Furthermore, the first roller shaft fixing member 12 includes a first fixing ring 121 that is in contact with the first air-floating sleeve 11. The first fixing ring 121 is connected to a first fixing edge 122 on a side facing away from the first air-floating sleeve 11. The first fixing edge 122 has two first free ends 123 for locking the ends of the roller 7. The two first free ends 123 can be locked by screws and nuts. A first air outlet groove 124 is provided between the first free end 123 and the first fixing ring 121. The first air outlet groove 124 is connected to the first air-floating sleeve 11.

[0049] The second roller shaft fixing member 22 includes a second fixing ring 221 that is in contact with the second air-floating sleeve 21. The second fixing ring 221 is connected to a second fixing edge 222 on the side facing away from the second air-floating sleeve 21. The second fixing edge 222 has two second free ends 223 for locking the ends of the roller 7. The two second free ends 223 can be locked by screws and nuts. A second air outlet groove 224 is provided between the second free end 223 and the second fixing ring 221. The second air outlet groove 224 is communicated with the second air-floating sleeve 21.

[0050] When locking the two first free ends 123, the two first free ends 123 need to have a certain degree of elasticity to ensure that the roller end is locked when locking. The setting of the first air outlet groove 124 also reduces the constraint of the first fixing ring 121 on the first free end 123, so that the two first free ends 123 can tightly embrace the roller 7; similarly, the function of the second free end 223 is the same as that of the first free end 123.

[0051] Furthermore, one end of the first air-floating sleeve 11 connected to the first roller shaft fixing member 12 is further provided with a first observation slot 113, and the end of the roller 7 is inserted into the first observation slot 113. The first observation slot 113 is used to observe the rotation of one end of the roller 7.

[0052] One end of the second air-floating sleeve 21 connected to the second roller shaft fixing piece 22 is further provided with a second observation slot 213, and the other end of the roller 7 extends into the second observation slot 213. The second observation slot 213 is used to observe the rotation of the other end of the roller 7.

[0053] Specifically, the length of the end of the roller 7 extending into the first observation slot 113 is 0.1-3 mm; the length of the end of the roller 7 extending into the second observation slot 213 is 0.1-3 mm.

[0054] Specifically, the length of the end of the roller 7 extending into the first observation slot 113 is 2 mm; the length of the end of the roller 7 extending into the second observation slot 213 is 2 mm.

[0055] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
