Description

[0002] In the key link of glass manufacturing, the stirring rod in the platinum channel realizes rotation by relying on chain transmission, so as to ensure that the glass liquid is uniformly mixed and stably flows. However, during the long-term operation of the equipment, the pin shaft and the sleeve frequently rotate relative to each other, which produces intense friction, causing the chain to inevitably appear relaxation and shaking due to factors such as wear and stretching. This chain relaxation and shaking problem is extremely harmful, which can cause the stirring rod speed to be unstable, and further seriously affect the mixing quality of the glass liquid, and even may cause equipment failure, greatly reduce the production efficiency and affect the product quality.

[0020] The tensioning mechanism includes a vertical rod 9 vertically fixedly installed at the end of the first rod body 2, the vertical rod 9 is provided to connect and support the first rod body 2 and the subsequent components, the upper end of the vertical rod 9 is vertically fixedly installed with a second rod body 10, the length direction of the second rod body 10 is parallel to the first direction, and this layout provides a suitable position and angle for the installation and work of the tensioning wheel set 11, the tensioning wheel set 11 is rotatably installed at the end of the second rod body 10 away from the screw rod 6, and the tensioning wheel set 11 can rotate flexibly on the second rod body 10 to efficiently cooperate with the stirring rod chain set;

The spring 4 provides an additional elastic force for the tensioning mechanism. When the chain is loose or subjected to external force impact, the spring 4 can automatically adjust the tensioning force through its expansion and contraction, thereby maintaining the stable tensioning state of the chain.

[0022] The tensioning wheel set 11 fully considers the actual working requirements of the stirring rod chain set. It includes a first tensioning wheel 111 movably installed on the upper end of the second rod body 10. The first tensioning wheel 111 is located on a second horizontal plane parallel to the first horizontal plane. The first chain in the stirring rod chain set is connected with the first tensioning wheel 111. The first tensioning wheel 111 adjusts the tensioning degree of the first chain by closely fitting and rotating with the first chain. Meanwhile, the tensioning wheel set 11 also includes a second tensioning wheel 112 movably installed on the upper end of the second rod body 10.

[0024] During daily production operation, when the stirring rod chain set is found to be loose, the operator can adjust it by rotating the screw rod 6 in the adjusting mechanism. When the screw rod 6 is rotated, it drives the first rod body 2 to move on the first horizontal plane due to the threaded transmission between the screw rod 6 and the turnover plate 7, and the connection relationship between the turnover plate 7 and the first rod body 2. The movement of the first rod body 2 changes the position of the tensioning mechanism installed on its end, thereby driving the tensioning wheel set 11 to apply tensioning force to the stirring rod chain set. During the adjustment process, the spring 4 automatically expands and contracts according to the actual tensioning state of the chain to assist in adjusting the tensioning force, thereby ensuring that the chain always maintains an appropriate tensioning degree. The operator can determine whether the adjustment is complete by observing the rotation of the stirring rod and the running state of the chain. When the stirring rod rotates at a stable speed and the chain does not have obvious looseness and shaking, it means that the adjustment is complete.
