Detailed Description

As shown in figures 1-2, the dual-purpose winding device for winding and unwinding of the open mill comprises a left support 1 and a right support 1, a winding mechanism 2 is arranged between the two supports 1, the winding mechanism 2 comprises an upper roller 3 and a lower roller 4, the upper roller 3 and the lower roller 4 are arranged on a rotating frame 5 through bearings on the left and the right, and the rotating frame 5 is rotatably arranged on the supports 1 through a short shaft and the bearings and is limited through a limiting mechanism. The upper roller 3 and the lower roller 4 are coaxially provided with chain wheels 6, the two chain wheels 6 are the same in size, chains 7 are wound on the two chain wheels 6, and the upper roller 3 is driven by a motor 8. When the motor 8 is driven, the upper roller 3 and the lower roller 4 synchronously rotate in the same direction.

As shown in fig. 3, the limiting mechanism comprises a limiting sleeve 9 mounted on the bearing seats of the upper roller 3 and the lower roller 4, and a threaded rod 10 mounted on the bracket 1, wherein the threaded rod 10 is in threaded connection with the bracket 1. When the upper roller 3 or the lower roller 4 is screwed to the lower part, the threaded rod 10 is opposite to the limit sleeve 9. The threaded rod 10 is screwed in, and the threaded rod 10 enters the limiting sleeve 9, so that the rotating frame 5 is limited to rotate.

As shown in fig. 2, the left and right brackets 1 are provided with a lifting moving mechanism, the lifting moving mechanism comprises a threaded rod 12 mounted on the beam 11 through a bearing, the threaded rod 12 is in threaded connection with a nut seat 13, a guide rod 14 is fixed above the other end of the nut seat 13, and the guide rod 14 is in sliding fit with a through hole on the beam 11 and can move up and down along the beam 11. A roller assembly 15 is arranged below the other end of the nut seat 13; when the threaded rod 12 is rotated, the threaded rod 12, the guide rod 14 and the roller assembly 15 move up and down in a straight line, when the roller assembly 15 is lower than the bottom end of the bracket 1, the roller assembly can move in a rolling manner, and when the roller assembly 15 is higher than the bottom end of the bracket 1, the bracket 1 is fixed on the ground.

In order to realize the synchronous action of the lifting moving mechanisms on the left side and the right side, the same belt pulleys 16 are arranged at proper positions at the lower ends of the left threaded rod 12 and the right threaded rod 12, and belts 17 are arranged on the two belt pulleys 16. The threaded rod 12 on one side is rotated and the threaded rod 12 on the other side is rotated synchronously. This provides for easier adjustment.

The working principle and the process are as follows: in the open mill process, the rubber coming out of the lower end of the open mill is manually wound on the lower roller 4, and after a circle of rubber is wound, the motor 8 is restarted, so that the rubber is matched with the lower roller 4 in a winding manner through controlling the rotating speed of the motor 8, and therefore the winding is completed. When the mill needs to be opened again, the threaded rod 10 is screwed out, the rotating frame 5 is rotated, the upper roller 3 and the lower roller 4 are changed in position, the rubber-coiled lower roller 4 reaches the upper part, the empty upper roller 3 reaches the upper part, and then the limiting sleeve 9 is screwed in, so that the limiting sleeve 9 is clamped into the limiting sleeve 9 of the upper roller 3. Then the rubber on the lower roller 4 with the rubber wound is dragged and put between two rollers of the open mill, and the open mill is started. And make motor 8 reversal, carry out the release of rubber, in the release process, empty upper roller 3 rolls up a round earlier through the manual work, and follow-up rolling by oneself is accomplished to the lower cylinder 4 release that the top was rolled up rubber.
