[0019] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the utility model includes a dehydrator conveyor belt 1, an electric drum assembly 3, a first idler assembly 4, a second idler assembly 5, a third idler assembly 6, a cycloidal pinwheel direct-connected speed reducer 9, and an air box 10; the electric drum on the electric drum assembly 3 that rotates counterclockwise meets the wet cake 2 in the dehydrator conveyor belt 1, turning the vertical wet cake 2 into a horizontal state. The electric drum rotates counterclockwise and meets the oncoming wet cake 2, which is more conducive to turning the vertical state of the wet cake 2 into a horizontal state. The cycloidal pinwheel direct-connected speed reducer 9 drives the first idler assembly 4 to rotate through a coupling 12; the idler gear 8 of the first idler assembly 4 drives the second idler assembly 5 to rotate through a first bridge gear 7, and the idler gear 8 of the second idler assembly 5 drives the third idler assembly 6 to rotate through a second bridge gear 13; the idlers on the first idler assembly 4, the second idler assembly 5, and the third idler assembly 6 successively roll over the wet cake 2 on the dehydrator conveyor belt 1, and the compressed air with a certain pressure in the air boxes 10 arranged on both sides of the dehydrator conveyor belt 1 blows the rolled wet cake 2 loose; the electric drum assembly 3, the first idler assembly 4, the second idler assembly 5, the third idler assembly 6, the cycloidal pinwheel direct-connected speed reducer 9, and the air box 10 are respectively connected to a frame 14. The dehydrator conveyor belt 1 is the conveyor belt of a cake dehydrator, and after conveying the wet cake 2 for this application, it is connected to an R611 type cake dryer in the next process.

[0020] Preferably, the heights of the first idler assembly 4, the second idler assembly 5, and the third idler assembly 6 from the dehydrator conveyor belt 1 decrease in sequence, and the diameter of the wet cake 2 is greater than the height of the first idler assembly 4 from the dehydrator conveyor belt 1. The three sets of idler assemblies with gradually decreasing heights successively roll over the wet cake 2, and the loosening effect is good; the first idler assembly 4, the second idler assembly 5, and the third idler assembly 6 rotate clockwise in sequence. The three sets of idler assemblies rotate clockwise in sequence, which is conducive to gradually rolling over the wet cake 2 in sequence, and the loosening effect is better.

[0021] Preferably, both ends of the first idler assembly 4, the second idler assembly 5, and the third idler assembly 6 are respectively connected to a bearing seat 11 through idler bearings 15, the bearing seat 11 is connected to the frame 14, and the idler bearings 15 are placed inside the bearing seat 11.

[0025] During use, the cake layer of the wet silk cake 2 after high-speed centrifugal dehydration by the present utility model is dense, and it is conveyed forward on the conveyor belt 1 of the dehydrator in a vertical state. The electric roller in the electric roller assembly 3 rotating counterclockwise meets the wet silk cake 2 and flips the vertical wet silk cake 2 into a horizontal state, which is convenient for later rolling and loosening. The horizontal wet silk cake 2 continues to move forward and meets the first idler assembly 4. The first idler assembly 4 rotating clockwise rolls the horizontal wet silk cake 2.

The second idler assembly 5 and the third idler assembly 6 with gradually decreasing heights continue to roll the horizontal wet silk cake 2, which can effectively improve the dense state of the inner layer of the wet silk cake. The compressed air in the air boxes on both sides of the conveyor belt 1 of the dehydrator blows the rolled wet silk cake 2 loose, so that when the loosened wet silk cake 2 enters the later R611 type silk cake dryer, it can be comprehensively and effectively dried, better meeting the production requirements.
