Description

Technical Field

[0001] This utility model relates to the technical field of multi-layer mesh belt dryers, specifically a multi-layer mesh belt dryer for drying light stabilizers. Background Technology

[0002] Light stabilizers are substances that inhibit or weaken the degradation effect of light on polymers, improving their light resistance. Under light, polymers are prone to photo-oxidation, leading to performance degradation. Light stabilizers can prevent or delay these reactions through various mechanisms, such as absorbing ultraviolet light and quenching excited-state molecules, thus extending the service life of polymer products. Drying light stabilizers removes moisture to prevent hydrolysis and other reactions that could affect their light stability. Currently, multi-layer mesh belt dryers are commonly used for drying light stabilizers. A multi-layer mesh belt dryer is a highly efficient drying device composed of multiple layers of stainless steel mesh belts with a certain spacing between each layer. The material is evenly spread on the mesh belts, and the movement of the mesh belts facilitates material transport within the dryer.

[0003] However, when using existing multi-layer mesh belt dryers, operators usually put the light stabilizer directly into the dryer from the feed inlet. However, when putting it in, the light stabilizer will be in the same position on the mesh belt, that is, the light stabilizer will accumulate when it is put into the dryer and cannot be spread to both sides of the mesh belt. This will result in the light stabilizer being wrapped up drying slowly or even not drying at all during the drying process. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-5 This utility model discloses a multi-layer mesh belt dryer for drying light stabilizers, including a dryer body 1, which is a multi-layer mesh belt dryer used for drying light stabilizers.

[0028] The top of the dryer body 1 is provided with a spreading component, which includes a lifting groove 11 and a lifting frame 12. The bottom of the lifting frame 12 is rotatably provided with a rotating shaft 13, and the rotating shaft 13 is provided with bidirectional spiral blades 14. The lifting frame 12 and the lifting groove 11 are slidably connected. A first motor 15 is provided on one side of the bottom of the lifting frame 12. The drive shaft of the first motor 15 is connected to the rotating shaft 13. A second motor 21 is provided above the lifting frame 12. A threaded rod 2 is provided on the drive shaft at the bottom of the second motor 21. A threaded opening 22 is provided on the inner side of the top of the lifting frame 12. The threaded rod 2 and the threaded opening 22 are threadedly connected.

[0029] That is, the second motor 21 drives the threaded rod 2 to rotate, thereby causing the lifting frame 12 and the bidirectional spiral blade 14 to descend, so that the bidirectional spiral blade 14 is on the inner stainless steel mesh belt. The first motor 15 drives the rotating shaft 13 and the bidirectional spiral blade 14 to rotate, and the bidirectional spiral blade 14 pushes to spread the light stabilizer on the stainless steel mesh belt.

[0030] A blocking component is provided on one side of the unfolding component. The blocking component includes a rectangular groove 23 and a blocking plate 31. A rectangular column 3 is provided on the top of the blocking plate 31. The rectangular column 3 is slidably connected to the rectangular groove 23. A rotating groove 24 is provided above the rectangular groove 23. A rotating rod 33 is rotatably provided inside the rotating groove 24. The rotating rod 33 is locked inside the rotating groove 24 and rotates. A guide block 34 is provided at the bottom of the rotating rod 33. A spiral guide rail 32 is provided inside the rectangular column 3. The guide block 34 is slidably connected to the spiral guide rail 32.

[0031] The third motor 43 drives the rotating disk 4 to rotate, and through the internal gear transmission, the ring tooth 35 rotates continuously in both directions, which drives the guide block 34 to rotate, thereby transmitting the transmission to the spiral guide rail 32. At this time, the rectangular column 3 and the baffle plate 31 are continuously raised and lowered. When the baffle plate 31 is at the bottom, it blocks the light stabilizer inside, thereby ensuring the spreading effect of the spreading component. Subsequently, the baffle plate 31 rises, thereby ensuring the delivery of the light stabilizer.

[0032] A limiting plate 44 is provided on one side of the baffle plate 31, and an electric telescopic rod 45 is provided on one side above the dryer body 1. The electric telescopic rod 45 is connected to the limiting plate 44. The position of the limiting plate 44 can be adjusted by the electric telescopic rod 45 to limit the height of the light stabilizer, thereby keeping the light stabilizer horizontal and ensuring the drying effect.

[0033] The working principle of this utility model is as follows: When the light stabilizer is added to the dryer, the second motor 21 drives the threaded rod 2 to rotate, thereby lowering the lifting frame 12 and the bidirectional spiral blades 14, so that the bidirectional spiral blades 14 are on the inner stainless steel mesh belt. The first motor 15 drives the rotating shaft 13 and the bidirectional spiral blades 14 to rotate, and the bidirectional spiral blades 14 push to spread the light stabilizer on the stainless steel mesh belt. The third motor 43 drives the rotating disk 4 to rotate, and through the internal gear transmission, the ring tooth 35 rotates continuously in both directions, thereby driving the guide block 34 to rotate, and thus transmitting to the spiral guide rail 32. At this time, the rectangular column 3 and the baffle plate 31 continuously rise and fall. When the baffle plate 31 is at the bottom, it blocks the light stabilizer inside, thereby ensuring the spreading effect of the spreading component. Subsequently, the baffle plate 31 rises, thereby ensuring the delivery of the light stabilizer. The position of the limiting plate 44 is adjusted by the electric telescopic rod 45 to limit the height of the light stabilizer, thereby keeping the light stabilizer horizontal and ensuring the drying effect.
