Description

Technical Field

[0001] This utility model relates to the mounting structure of rollers, and more specifically, it relates to the mounting mechanism of a surface paint roller. Background Technology

[0002] The surface paint roller is mainly mounted on the frame via a drive unit and a support unit. The drive unit drives the surface paint roller to rotate, while the support unit supports it to ensure stable rotation. For example, a surface paint roller for flattening composite wood mats, disclosed in CN221472403U, has a honeycomb surface design. Therefore, when the surface paint roller is not used for a long time, it needs to be disassembled to clean the paint inside the honeycomb to prevent it from solidifying. Currently, surface paint rollers use two shafts connected by a key to achieve disassembly and installation. However, since the two shafts are mounted on the drive unit and the support unit respectively, disassembly requires removing the flange bolts, first removing the support unit, and then removing the support unit and its connected shaft together before the roller can be taken out. This disassembly method requires complete disassembly of the support unit, which is complex and time-consuming. Therefore, this invention proposes an installation mechanism for the surface paint roller to achieve rapid disassembly and installation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an installation mechanism for a surface paint roller that addresses the shortcomings of the existing technology, thereby achieving the effect of quick assembly and disassembly of the surface paint roller.

[0006] Preferably, the surface paint roller has multiple circular weight-reducing holes.

[0007] Preferably, the first weight-reducing hole has a threaded section at one end near the first shaft, a positioning plug is screwed into the threaded section, a spring telescopic column is installed on one side of the positioning plug, a connecting block is fixed at the end of the spring telescopic column, a screw is screwed into the connecting block, the flange on the first shaft has a strip-shaped through hole, the screw is inserted into the strip-shaped through hole, and a slotted positioning strip is provided at the end of the screw.

Detailed Implementation

[0014] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention. See Figures 1-8 This utility model discloses an installation mechanism for a surface paint roller, comprising a drive unit 1 and a support unit 5 mounted on a frame. A surface paint roller 3 is disposed between the drive unit 1 and the support unit 5. A sliding mechanism 6 is provided between the frame and the support unit 5 to drive the support unit 5 to move along the axial direction of the surface paint roller 3. The distance between the drive unit 1 and the support unit 5 can be changed by moving the support unit 5 through the sliding mechanism 6. The output end of the drive unit 1 is provided with a shaft body 2, and the support unit 5 is provided with a shaft body 4 rotatably connected to it. The surface paint roller 3 is provided with a shaft hole, and a connecting shaft 7 is fixedly disposed in the shaft hole. Both ends of the shaft body 2 and the shaft body 4 are provided with connecting keys 8. Both ends of the connecting shaft 7 are provided with keyways that match the connecting keys 8. The shaft body 2 and the shaft body 4 are respectively inserted into the two ends of the shaft hole, and the connecting keys 8 are inserted into the keyways. The key connection structure enables the transmission connection between the drive unit 1, the carrier unit 5 and the surface paint roller 3. This transmission connection is detachable. With the change of the distance between the drive unit 1 and the carrier unit 5, the surface paint roller 3 located between the two can be quickly assembled and disassembled.

[0015] In this embodiment, flanges 9 are fixed to the periphery of both shaft 2 and shaft 4, and multiple internal threaded sleeves are fixed to both ends of the surface paint roller 3. The flanges 9 are connected to the internal threaded sleeves by bolts. The connection between the shafts and the surface paint roller 3 via the flanges 9 achieves a better fixing effect on the surface paint roller 3.

[0016] In addition, multiple circular weight-reduction holes 10 are provided in the surface paint roller 3. A second weight-reduction hole is also provided between the first weight-reduction hole 10 and the shaft hole to further reduce the overall weight of the surface paint roller 3, achieving lightweighting. The weight-reduction hole 10 is circular instead of the traditional fan-shaped shape, mainly to match the installation of the pushing mechanism.

[0017] The pushing mechanism of this embodiment includes a positioning plug 11, a spring telescopic column 12, a connecting block 13, a screw 14, and a one-line positioning strip 15. Its function is that during the disassembly of the surface paint roller 3, when the bearing part 5 is driven away from the driving part 1, the surface paint roller 3 can automatically slide and separate from the flange 9 installed on the shaft body 2 under the action of the spring force of the spring telescopic column 12.

[0018] Specifically, the weight-reducing hole 10 has a threaded section at one end near the shaft 2, and a positioning plug 11 is screwed into the threaded section. A spring telescopic column 12 is installed on one side of the positioning plug 11. The spring telescopic column 12 is a telescopic rod with an internal spring, which is existing technology and is not improved by this invention. A connecting block 13 is fixed to the end of the spring telescopic column 12. The diameter of the connecting block 13 is larger than the width of the strip-shaped through hole 16, allowing the flange 9 to limit the connection block 13, thus enabling the spring telescopic column 12 to be compressed under the action of the flange 9 and the positioning plug 11. A screw 14 is screwed into the connecting block 13. The flange 9 on the shaft 2 has a strip-shaped through hole 16, and the screw 14 is inserted into the strip-shaped through hole 16. A slotted positioning strip 15 is provided at the end of the screw 14. The length and width of the strip-shaped through hole 16 are both larger than the slotted positioning strip 15. When the position of the locating strip 15 does not match the position of the strip-shaped through hole 16, the flange 9 forms a blockage against the locating strip 15. When the surface paint roller 3 moves to the end of the shaft 2 under the action of the spring force and there is a slight overlap, such as... Figure 5 As shown, at this time, the spring telescopic column 12 is at its maximum extension length. Under the positioning action of the straight positioning strip 15, there will be no more axial displacement between the surface paint roller 3 and the shaft body 2, thus avoiding the risk of the surface paint roller 3 falling and being damaged. When the straight positioning strip 15 rotates to the position of the strip-shaped through hole 16, the straight positioning strip 15 can pass through the strip-shaped through hole 16. At this time, the surface paint roller 3 can be removed from the shaft body 2, separating the two.

[0019] To prevent the straight positioning strip 15 from freely rotating and entering the strip-shaped through hole 16, mushroom-shaped nails 17 made of rubber are inserted into both ends of the strip-shaped through hole 16 in this embodiment. To facilitate insertion of the mushroom-shaped nails 17 into the strip-shaped through hole 16, their ends are designed to be tapered. The interference fit design of the mushroom-shaped nails 17 ensures they are securely positioned within the strip-shaped through hole 16, reducing the risk of them falling out. The protruding portion of the mushroom-shaped nails 17 also blocks the rotation of the straight positioning strip 15, preventing it from falling into the area of ​​the strip-shaped through hole 16.

[0020] The present invention provides the following two embodiments for the sliding mechanism.

[0021] Implementation Method 1 The sliding mechanism 6 includes a slide rail and a rack. The supporting part 5 is equipped with a gear mechanism, which is slidably mounted on the slide rail. The gear in the gear mechanism meshes with the rack. A reduction gear mechanism is preferred for the gear mechanism, allowing for more precise control of the movement position of the supporting part 5. The gear mechanism is connected to a handle for rotating its internal gear. It should be noted that the sliding mechanism, consisting of a slide rail, rack, and gear mechanism, has mature applications in the mechanical field; therefore, its more specific structure and working principle will not be elaborated upon in this paper.

[0022] Implementation Method 2 The sliding mechanism 6 is a linear module, which is mounted on the frame, and the bearing part 5 is mounted on the slider of the linear module.

[0023] The working principle of this utility model is as follows: Taking the disassembly of the surface paint roller 3 as an example, firstly, remove the bolts on the flange 9. At this time, under the joint support of the two shafts, the surface paint roller 3 will not fall off. Then, activate the sliding mechanism 6 to drive the bearing part 5 to move away from the driving part 1. Previously, since the spring in the spring telescopic column 12 was in a compressed state, when the sliding mechanism 6 is activated, as the sliding mechanism 6 moves, the spring telescopic column 12 will extend, thereby pushing the surface paint roller 3 to move towards the shaft 2 4, so that the surface paint roller 3 separates from the flange 9 of the shaft 2.

[0024] During this process, if the spring telescopic column 12 extends to its maximum length, there will still be an overlap between the surface paint roller 3 and the shaft 2. Furthermore, under the positioning action of the locating strip 15, the distance between the surface paint roller 3 and the flange 9 on the shaft 2 will not change, preventing one end of the surface paint roller 3 from falling off. As the sliding mechanism 6 continues to move, the surface paint roller 3 will then separate from the flange 9 on the shaft 4.

[0025] When the surface paint roller 3 and the shaft 2 4 have a slight overlap, the sliding mechanism 6 can be stopped. Next, the surface paint roller 3 is hoisted, and after hoisting, the mushroom-shaped nail 17 can be removed. The straight positioning strip 15 is then rotated to align with the strip-shaped through hole 16. The sliding mechanism 6 is then restarted to separate the shaft 2 4 from the surface paint roller 3, ensuring a safe distance between them. Finally, the surface paint roller 3 is moved slightly away from the drive unit 1 using the hoisting device to separate it from the shaft 2, after which the surface paint roller 3 can be removed.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
