DETAILED DESCRIPTION
[0013] The utility model provides a small corn flaking roller gap adjustment device, such as Figure 1 As shown, the first fixed support 8, the second fixed support 20 and the third fixed support 21 are sequentially installed on the support plate 18, the hydraulic cylinder 1 is installed on the first fixed support 8, the L-shaped rotating seat 12 is installed on the second fixed support 20 through the support shaft 9, the first fixed support 8 and the rotating seat 12 are connected by a pulling assembly, one end of the pull rod 4 of the pulling assembly is installed on the first fixed seat 8 through a limit cover 2 and an adjusting nut 3, the other end of the pull rod 4 is connected to the rotating seat 12 through a connecting rod shaft 11, a disc spring 6 is installed between the limit cover 2 and the first fixed support 8, and the pull rod 4 is connected to the rotating seat 12. The adjusting nut 3 is installed on the other side of the limit cover 2; the first seat bearing 13 is installed on one side of the rotating seat 12, and the roller 5 is installed on the first seat bearing 13. The other side of the rotating seat 12 is connected to the supporting outer wall 17 through the top shaft 10, and the supporting outer wall 17 is connected to the piston cylinder 22. The push plate 15 is installed on the inner wall of the piston cylinder 22 through the central shaft 16. The piston rod of the hydraulic cylinder 1 is connected to the push plate 15, and an elastic body 7 is arranged between the push plate 15 and the supporting outer wall 17. The second seat bearing 19 is installed on the third fixed support 21, and the fixed roller 14 is installed on the second seat bearing 19. Since the corn flakes are very thin, when the device is assembled, the part that needs to be rotated is installed through clearance fit, so that the position of the roller 5 can be moved.
[0014] During operation, by pressurizing the hydraulic cylinder 1, the piston 23 of the hydraulic cylinder 1 extends out, and the piston 23 first contacts the push plate 15. The push plate 15 is lifted under the thrust of the piston 23, so that the piston 23 pushes the elastic body 7 to compress and pushes the roller 5 in the direction of the fixed roller 14. At this time, the tie rod 4 is tightened, and the butterfly spring 6 is compressed by force. When it is compressed to a certain extent, the limit cover 2 contacts the first fixed support 8, and the butterfly spring 6 stops deforming. Due to the action of the limit cover 2, the movement of the tie rod 4 is limited, and then the position of the roller 5 is limited. At this time, the elongation of the tie rod 4 can be adjusted by rotating the adjustment nut 3 to control the moving position of the roller 5, so as to adjust the gap between the roller 5 and the fixed roller 14. When the hydraulic cylinder 1 is depressurized, the butterfly spring 6 releases the pressure, pulls the roller 5 back, and realizes the roller separation. The whole process of adjusting the gap between the roller 5 and the fixed roller 14 is completed. During operation, the pressure of the hydraulic cylinder 1 is equal to the elastic force of the elastic body 7, and the elastic body 7 still has a deformation margin. When a foreign object stretches the roller 5, the elastic body 7 can be compressed and buffered to allow the foreign object to pass.
