It can be understood that the aforementioned solution can rotate and place roller workpieces of different sizes, thereby increasing the applicability of the placement stand.

[0023] In this embodiment, the base 101 is made of stainless steel, and the base 101 provides conditions for the installation of the movable bracket 102, the universal wheel 103 and the adjustable supporting device. There are two movable brackets 102, which are mounted on the upper end of the base 101 and are positioned on the base 101 on both sides by bolts. The two movable brackets 102 provide conditions for the installation of the adjustable supporting device. The two movable brackets 102 are suitable for the placement of rollers of different sizes and lengths, which is convenient and practical. There are four universal wheels 103, which are respectively installed at the four diagonal positions at the bottom of the base 101 to facilitate the movement of the placement rack.

[0024] The guide rail 104 is fixedly connected to the movable bracket 102 and is located at the top of the movable bracket 102. The mounting slider 105 is slidably connected to the guide rail 104 via the movable adjustment assembly and extends into the guide rail 104. The movable adjustment assembly is connected to the mounting slider 105 and drives the mounting slider 105 to move. The arc-shaped support block 106 is fixedly connected to the mounting slider 105 and is located at the top of the mounting slider 105. The supporting roller 107 is rotatably connected to the arc-shaped support block 106 and is located at the upper end of the arc-shaped support block 106. The slide groove 113 is provided at the upper end of the guide rail 104 and matches the mounting slider 105.

The guide rails 104 are rectangular in structure and are provided with the slide groove 113 with an upward opening. The cross section of the slide groove 113 is convex in shape, which matches the shape of the mounting slider 105. The rotation limit of the mounting slider 105 is achieved by matching the shape of the mounting slider 105 with the slide groove 113, so that the mounting slider 105 can only move horizontally in the slide groove 113. The slide groove 113 also provides a mounting condition for the bidirectional screw 108 of the mobile adjustment component. The two ends of the guide rail 104 are provided with two mounting holes 114 communicating with the slide groove 113. The mounting holes 114 are used for the movement adjustment component to extend into the slide groove 113 and connect with the two mounting sliders 105 in the slide groove 113. The two mounting sliders 105 in the guide rail 104 are connected by the movement adjustment component, and the two mounting sliders 105 can be synchronously driven to move closer to or away from each other in the slide groove 113. The arc-shaped supporting blocks 106 are fixed on the two mounting sliders 105, and the two arc-shaped supporting blocks 106 are connected. Symmetrical installation, an arc-shaped groove is provided on the opposite side of the two arc-shaped supporting blocks 106, which provides conditions for the installation of the supporting roller 107. The upper end of the arc-shaped groove of the arc-shaped supporting block 106 is rotatably installed with the supporting roller 107 through the rotating shaft. The two ends of the roller workpiece are dragged by the two supporting rollers 107 on the two movable brackets 102, and can be rotated to facilitate cleaning and maintenance operations on the roller workpiece; therefore, the installation spacing between the two movable brackets 102 is adjusted according to the size and length of the roller workpiece, and then the movable adjustment on the two movable brackets 102 is adjusted. The components respectively adjust the two mounting slide blocks 105 in the slide grooves 113 of the two guide rails 104 to move closer to or away from each other, and the arc-shaped supporting blocks 106 on the two mounting slide blocks 105 adjust the spacing according to the size and diameter of the roller workpiece to support roller workpieces of different sizes, and the supporting roller 107 rotatably mounted on the arc-shaped supporting block 106 is in rotational contact with the roller workpiece, so that the roller workpiece can be rotated. Therefore, the adjustable supporting device can facilitate the rotation and placement of roller workpieces of different sizes, thereby increasing the scope of application of the placement rack.

[0025] Secondly, the bidirectional screw 108 is rotatably connected to the guide rail 104 through the bearing 109, and is threadedly connected to the mounting slider 105; one side of the bearing 109 is fixedly connected to the bidirectional screw 108, and the other side of the bearing 109 is fixedly connected to the guide rail 104, and the bearing 109 rotatably connects the bidirectional screw 108 and the guide rail 104; the rotation output end of the drive motor 110 is fixedly connected to the bidirectional screw 108, and the drive motor 110 is located at one end of the bidirectional screw 108; the mounting slider 105 has a threaded hole 111, and the threaded hole 111 is arranged on the mounting slider 105, passes through the mounting slider 105, and cooperates with the bidirectional screw 108.

The threads at both ends of the bidirectional screw 108 have opposite directions and match the inner threads of the threaded holes 111 of the mounting sliders 105 respectively sleeved on the two ends of the bidirectional screw 108. By rotating the bidirectional screw 108, the two sleeved mounting sliders 105 can be simultaneously driven to move closer to or away from each other under the limit of the slide grooves 113 of the guide rail 104. The bearings 109 are fixedly connected to both ends of the bidirectional screw 108. The inner diameter of the inner ring of the bearing 109 matches the diameter of the bidirectional screw 108, and the outer diameter of the outer ring of the bearing 109 matches the diameter of the mounting hole 114 of the guide rail 104, and matches the side of the mounting hole 114. The guide rail 104 is fixedly connected to the bidirectional screw 108, and the bidirectional screw 108 is rotatably installed on the bearing 109 through the bearing 109. The drive motor 110 is located at the right end of the outer side of the guide rail 104, and the rotation output end of the drive motor 110 faces the bidirectional screw 108 and is fixedly connected to the end of the bidirectional screw 108.

The bottom of the mounting base 112 is rectangular, and its two ends are fixedly mounted on the movable bracket 102 by bolts. The mounting base 112 realizes a detachable connection between the drive motor 110 and the movable bracket 102, which facilitates the maintenance or replacement of the drive motor 110.

[0027] When using the mobile roller placement rack for nano-light guide plate production of the utility model, the installation spacing between the two movable brackets 102 is adjusted according to the size and length of the roller workpiece, and then the two installation sliders 105 in the slide grooves 113 of the two guide rails 104 are adjusted respectively by the movable adjustment components on the two movable brackets 102 to move closer to or away from each other, and the arc-shaped supporting blocks 106 on the two installation sliders 105 adjust their spacing according to the size and diameter of the roller workpiece to support roller workpieces of different sizes, and the supporting roller 107 rotatably mounted on the arc-shaped supporting block 106 is in rotational contact with the roller workpiece, so that the roller workpiece can be rotated. Therefore, the adjustable supporting device can facilitate the rotation and placement of roller workpieces of different sizes, thereby increasing the scope of application of the placement rack.
