[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Example 1, please refer to Figures 1-4 , the present invention provides a technical solution: a noise-reducing inner barrel support frame of a dryer, including an upper fixing ring 1, a lower fixing ring 2 and a circular bottom plate 3. A plurality of buffer and shock absorption assemblies 4 are fixedly connected in an annular array between the lower fixing ring 2 and the circular bottom plate 3. A plurality of support steel pipes 5 are fixedly connected in an annular array between the upper fixing ring 1 and the lower fixing ring 2. A plurality of limiting wheels 6 are rotatably connected to the outer surface of the support steel pipe 5. A rubber sleeve 7 is fixedly connected to the outer surface of the limiting wheel 6. The rubber sleeve 7 is used to tightly press against the inner barrel of the dryer. By setting the upper fixing ring 1, the lower fixing ring 2, the circular bottom plate 3 and a plurality of buffer and shock absorption assemblies 4, a support frame structure can be formed. Using the rubber sleeve 7 to tightly press against the inner barrel of the dryer and cooperating with the rotation of the limiting wheel 6 can effectively reduce the noise generated by the inner barrel of the dryer. By rotating the limiting wheel 6, the rotation of the inner barrel of the dryer is not affected, and the overall shock absorption effect is good, effectively improving the service life of the support frame.

[0023] The buffer and shock-absorbing assembly 4 includes a connecting support plate 8, a first universal joint 9, a first baffle 10, a damper 11, a spring 12, a second baffle 13 and a second universal joint 14. The connecting support plate 8 is fixedly connected to the outer surface of the lower fixed ring 2. The fixed end of the first universal joint 9 is mounted on the surface of the connecting support plate 8. The movable end of the first universal joint 9 is fixedly connected to the first baffle 10. The fixed end of the second universal joint 14 is fixedly connected to the surface of the circular bottom plate 3. The movable end of the second universal joint 14 is fixedly connected to the second baffle 13. The damper 11 is fixedly connected between the first baffle 10 and the second baffle 13, and the spring 12 is sleeved on the outer surface of the damper 11. When the inner barrel of the dryer rotates, if the inner barrel is skewed, through the rotation of the first universal joint 9 and the second universal joint 14, the inclination of the buffer and shock-absorbing assembly 4 can be made consistent with the inclination of the inner barrel, so that the rubber sleeve 7 can closely adhere to the inner barrel of the dryer, thereby buffering and protecting the inner barrel of the dryer. And by using the expansion and contraction of the spring 12 in cooperation with the damper 11 to absorb elastic potential energy, a buffering and shock-absorbing effect can be achieved, thus playing a good buffering and shock-absorbing role as a whole and effectively reducing the noise generated by the inner barrel of the dryer.

[0024] The number of the limiting wheels 6 on the outer surface of each support steel pipe 5 is three, and the spacing between the three limiting wheels 6 is equal. By arranging the three limiting wheels 6, it can effectively prevent the inner barrel of the dryer from colliding with the support steel pipe 5 or the dryer housing during rotation, thereby avoiding the occurrence of collision noise.

[0025] The upper fixed ring 1, the lower fixed ring 2, the circular bottom plate 3 and the support steel pipe 5 are all made of stainless steel, which can effectively improve the structural strength of the entire support frame and at the same time avoid rust and corrosion.

[0026] A plurality of ear plates 15 are fixedly connected to the outer surface of the upper fixed ring 1 in an annular array. Through holes are provided on the surfaces of the ear plates 15, and hooks 16 are hung in the through holes. The end of the hook 16 is fixedly connected to a tension spring 17. The end of the tension spring 17 away from the hook 16 is fixedly connected to the outer cylinder of the dryer. By arranging the ear plates 15, the hooks 16 and the tension spring 17, using the tension spring 17 to pull the hook 16 and then using the hook 16 to pull the ear plate 15, the upper fixed ring 1 can be limited, thereby limiting the inner barrel of the dryer and making it not easy to be skewed when the inner barrel of the dryer rotates. At the same time, the tension spring 17 expands and contracts, which can play a buffering role, thereby further reducing the working noise of the dryer.

[0027] Example 2, please refer to Figures 1-4, including Embodiment 1, and based on Embodiment 1, the present utility model provides a technical solution: The lower fixing ring 2 is a tubular structure, and the lower fixing ring 2 communicates with the support steel pipe 5. A hot air blower 18 is fixedly connected to the surface of the circular bottom plate 3. An air delivery hose 19 is arranged at the output end of the hot air blower 18. One end of the air delivery hose 19 away from the hot air blower 18 is fixedly communicated with the lower fixing ring 2. A plurality of hot air holes 20 are formed on the surface of the support steel pipe 5, and the hot air holes 20 are directly opposite to the central axis of the circular bottom plate 3. By arranging the hot air blower 18, the air delivery hose 19 and the hot air holes 20, when the hot air blower 18 works, hot air can be conveyed from the air delivery hose 19 into the lower fixing ring 2 and then sprayed out from the hot air holes 20 on the surface of the support steel pipe 5, so that the inner cylinder of the dryer can be air-dried and heated, effectively improving the drying efficiency of the dryer. At the same time, the inner barrel of the dryer is kept dry, and the breeding of bacteria is also effectively avoided.
