Description

Technical Field

[0001] This utility model relates to the field of placement rack technology, specifically a placement rack for coating roller processing. Background Technology

[0002] Coating rollers are key components widely used in industrial production, especially in printing, coating, and laminating industries. They typically have a cylindrical roller structure and may be covered with rubber, polyurethane, or other functional coatings. They are relatively soft and require extremely high surface finish. During production breaks, maintenance, or transfer, how to safely and stably store and handle coating rollers to prevent them from rolling, colliding, being squeezed and deformed, or having surface scratches is an important aspect of ensuring their service life and processing quality. Traditionally, coating rollers are placed directly on the ground or on simple supports. This method has obvious drawbacks: First, the rollers are in direct contact with hard surfaces, making them prone to surface damage due to rolling or friction. Second, when multiple layers are stacked, the coating rollers at the bottom bear enormous pressure, which can easily cause permanent deformation, affecting their dynamic balance and accuracy. In addition, when movement is required, it is inconvenient to handle, poses safety hazards, and is inefficient. Existing technologies include some supports or racks for placing roller-type workpieces, but they are typically single-function. For example, some fixed-height supports cannot flexibly adapt to coating rollers of different diameters or quantities, resulting in low space utilization or poor applicability. Others, while featuring simple limiting structures, are often cumbersome to operate, making it inconvenient to pick up or put down the rollers. Furthermore, during movement, the rollers may still disengage due to vibration, indicating insufficient stability. Additionally, most racks lack an effective overall lifting and adjustment mechanism, making alignment difficult when unloading or installing coating rollers from equipment, increasing the labor intensity for workers. Therefore, improvements to existing technologies are needed. Utility Model Content

A drive seat 15 is fixedly installed on the upper end of the slide rod 14. A support spring 17 is provided on the outside of the slide rod 14.

[0017] Please see Figure 1-8 The base 1 has multiple evenly distributed casters 5 installed at its lower end. The guide frame 2 is in contact with the placement frame 4. The screw 7 is connected to the internal threaded tube 6 by a thread. The casters 5 make the base 1 easier to move. The coating roller 11 is slidably placed inside the groove of the support frame 9. The coating roller 11 is in contact with the limiting frame 10. The upper end of the support frame 9 is fixedly installed with a positioning post 12. The positioning post 12 is slidably connected to the limiting frame 10. The positioning post 12 can limit the limiting frame 10. The elongated hole of the drive seat 15 is movably connected to the drive frame 13. The lower end of the slide rod 14 is fixedly installed with a pull ring 16. The pull ring 16 is in contact with the placement frame 4. The pull ring 16 can drive the drive seat 15 to move downward through the slide rod 14. One end of the support spring 17 is fixedly connected to the drive seat 15. The other end of the support spring 17 is fixedly connected to the placement frame 4. The support spring 17 is located inside the groove of the placement frame 4. The support spring 17 can support the drive seat 15 with its elastic force.

[0018] Please see Figure 1-8The stabilizing drive mechanism 8 includes a worm gear 81. The worm gear 81 is fixedly installed on the lower outer side of the screw 7. Two symmetrically distributed drive covers 82 are fixedly installed on the upper end of the base 1. The interior of the two drive covers 82 is connected to a synchronous rotating shaft 83 via bearings. Two symmetrically distributed worms 84 are fixedly installed on the outer side of the synchronous rotating shaft 83. Both ends of the synchronous rotating shaft 83 are fixedly installed with drive handwheels 85. The drive handwheels 85 drive the synchronous rotating shaft 83 to rotate. The worms 84 and worm gear 81 are both located inside the drive cover 82. The worms 84 mesh with the worm gear 81. The interior of the drive handwheel 85 is connected to a handle 86 via bearings. The handle 86 makes it easier to rotate the drive handwheel 85.

[0019] The specific implementation process of this utility model is as follows: Lifting principle: The operator rotates the drive handwheel 85, which drives the synchronous rotating shaft 83 and the two worm gears 84 on it to rotate synchronously. The rotation of the worm gears 84 drives the two worm wheels 81 meshing with them to rotate synchronously. Since the worm wheels 81 are fixedly connected to the screw 7, the two screws 7 also rotate synchronously. The screw 7 and the internal threaded tube 6 fixed at the bottom of the placement frame 4 form a threaded pair. When the screw 7 rotates, the internal threaded tube 6 drives the entire placement frame 4 to move vertically upward or downward along the guide rod 3. The guide rod 3 slides in the guide frame 2 to prevent the placement frame 4 from rotating and ensure that it only makes linear motion. The inherent reverse self-locking characteristics of the worm wheel 81 and worm gear 84 mechanism make it possible for the placement frame 4 to be stably suspended at any height when the drive handwheel 85 stops rotating, without sliding down on its own due to the weight it bears, thus ensuring operational safety. Limiting and locking principle: Under the elastic force of the support spring 17, the drive seat 15 is subjected to an upward thrust. This upward force is transmitted to the drive frame 13 through the elongated hole on the drive seat 15, and is converted into a component force that causes the drive frame 13 to swing inward, i.e., to move closer to each other. This inward force is transmitted to the limiting frame 10 through the drive frame 13, forcing the limiting frame 10 to rotate upward around its hinge point with the support frame 9, thereby firmly pressing the coating roller 11 placed in the groove of the support frame 9, and achieving locking. When it is necessary to pick up or put down the coating roller 11, the operator pulls down the pull ring 16. The pull ring 16 drives the slide bar 14 and the drive seat 15 to move down together, further compressing the support spring 17. After the drive seat 15 moves down, its elongated hole releases the inward pressure on the drive frame 13. At the same time, the drive frame 13 can drive the limit frame 10 to flip down, making room for picking up or putting down the coating roller 11. After the coating roller 11 is placed, the pull ring 16 is released. Under the restoring force of the support spring 17, the drive seat 15 moves up automatically and pushes the limit frame 10 to reset again through the drive frame 13. After the limit frame 10 is reset, the automatic locking of the coating roller 11 can be completed.
