Detailed implementation manner

[0022] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0023] Referring to Figures 1 - 4 , an embodiment provided by the present invention includes a second mounting plate 1 corresponding to one end of the first mounting plate 6. The lower end of the first mounting plate 6 is fixedly connected to a second support column 9. One side of the second support column 9 is fixedly connected to a support frame 8. The support frame 8 connects the second support column 9 and the motor 7 to each other and supports the motor 7 to ensure the stable output of the motor 7. The other end of the support frame 8 is fixedly connected to a motor 7. The output end of the motor 7 penetrates through the first mounting plate 6 and is fixedly connected to a second rotating shaft 10. The other end of the second rotating shaft 10 is movably connected to a roller cylinder 5. The other end of the roller cylinder 5 is movably connected to a first rotating shaft 4. The motor 7 drives the second rotating shaft 10 to rotate, and the second rotating shaft 10 further drives the roller cylinder 5 to rotate, and also makes the first rotating shaft 4 rotate, realizing the power supply of the entire roller assembly. The lower end of the first mounting plate 1 is fixedly connected to a first support column 2. The first rotating shaft 4 is rotatably connected to the first mounting plate 6. The first support column 2 and the second support column 9 support the entire roller assembly.

[0024] Grooves 11 are provided inside both the first rotating shaft 4 and the second rotating shaft 10. The grooves 11 correspond to the mounting blocks 13 at both ends of the roller cylinder 5. In order to quickly and conveniently make the positions of the roller cylinder 5 and the first rotating shaft 4 correspond, two fixed grooves 12 are opened outward on both sides of the groove 11. The fixed grooves 12 facilitate the quick positioning and clamping of the fixed blocks 14, so that the roller assembly will not fall off during subsequent use.

[0025] Both ends of the roller tube 5 are fixedly connected with mounting blocks 13. Two limiting grooves 17 are opened outward inside the mounting blocks 13. Fixed blocks 14 are movably connected to both sides of the mounting blocks 13. One end of the limiting groove 17 is fixedly connected with a spring 15, and the other end of the spring 15 is fixedly connected with a limiting plate 16. The limiting plate 16 is fixedly connected with the fixed block 14. The limiting groove 17 enables the spring 15 not to shift in position during retraction and extension, thereby ensuring that the position of the fixed block 14 does not shift, so that the fixed block 14 will not be misaligned when it is correspondingly clamped with the fixed groove 12, realizing convenience and quickness during clamping. The limiting plate 16 prevents the reaction force generated by the spring 15 from being too large and causing the spring 15 to pop out of the mounting block 13, making the position of the fixed block 14 relatively stable.

[0026] The other ends of the first support column 2 and the second support column 9 are fixedly connected with self-locking wheels 3. The installation of the self-locking wheels 3 can make the whole roller assembly move more labor-saving, and there will be no shaking and offset when installing the roller tube 5 and the rotating shaft. The fixed block 14 corresponds to the fixed groove 12, and the groove 11 corresponds to the mounting block 13. The corresponding connection between the fixed block 14 and the fixed groove 12 can prevent the roller tube 5 and the first rotating shaft 4 from falling off due to long-term use in the future. The corresponding connection between the groove 11 and the mounting block 13 can enable the position during the installation of the roller tube 5 and the first rotating shaft 4 to be quickly clamped, thereby realizing convenience and quickness in connection.

[0027] Working principle: First, hold the fixed blocks 14 at both ends of the mounting block 13. Since a groove 11 is opened inside the first rotating shaft 4 and a fixed groove 12 is opened outward in the groove 11, the mounting block 13 is made to correspond to the groove 11, and the roller tube 5 can be pushed into the groove 11. Since a limiting groove 17 is opened inside the mounting block 13, a spring 15 is installed inside the limiting groove 17, and the spring 15 is connected to the fixed block 14. When holding the fixed block 14, the fixed block 14 will retract into the limiting groove 17, so that the roller tube 5 can be placed into the groove 11. When the fixed block 14 corresponds to the fixed groove 12, the reaction force generated by the spring 15 will cause the fixed block 14 to pop out and just be clamped with the fixed groove 11. Then, use the same method to clamp the fixed block 14 at the other end of the roller tube 5 with the fixed groove 12 inside the second rotating shaft 10. Finally, start the motor 7 to drive the first rotating shaft 4 to rotate, and the first rotating shaft 4 further drives the roller tube 5 to rotate.

[0028] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
