Description

Technical Field

[0001] The utility model relates to the field of cover glass channel equipment, in particular to a platinum channel stirring rod connection structure. Background Art

[0002] During normal use of the substrate glass or cover glass channel equipment, the platinum channel stirring rod is installed on the channel stirring mechanism. The channel stirring mechanism drives the platinum stirring rod to rotate in the glass liquid in the platinum channel stirring tank according to the speed and direction required by the process, thereby homogenizing the glass liquid in the stirring tank, further improving the quality of the glass liquid, and meeting the process requirements.

[0003] Existing stirring equipment often uses bearings to limit the power shaft, such as a material reactor with publication number CN206545026U. Existing technology provides minimal restrictions on the operation of platinum stirring rods, lacking a suitable limiting device. As the stirring rod rotates, its long length and wide swing amplitude can easily cause the stirring rod blades to scrape against the inner wall of the stirring tank, damaging the stirring tank wall and blades. The scraped platinum can then enter the glass liquid in the stirring tank, degrading its quality. Improper limiting methods can severely affect the stirring effect of the platinum stirring rod, thereby affecting the quality of the glass liquid in the stirring tank and seriously impacting normal channel production.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1 As shown, a platinum channel stirring rod connection structure includes a drive shaft 1 and a stirring shaft 5 connected to each other. A sleeve structure 3 is provided at the connection between the drive shaft 1 and the stirring shaft 5. The bottom of the sleeve structure 3 is installed on the stirring tank body 4 through a flange 6. The upper part of the sleeve structure 3 is fixed by a fastening ring 2. The drive shaft 1 and the stirring shaft 5 are respectively connected inside the sleeve structure 3 through bearings.

[0024] Example 2

[0025] like Figure 2 – Figure 4 As shown, a platinum channel stirring rod connection structure, the sleeve structure 3 includes two semicircular sleeves, an upper bearing mounting groove 11 and a lower bearing mounting groove 12 are respectively provided in the semicircular sleeves, an upper bearing 9 is installed between the upper bearing mounting groove 11 and the drive shaft 1, and a lower bearing 10 is installed between the lower bearing mounting groove 12 and the stirring shaft 5; the inner side of the upper bearing 9 is connected to the drive shaft 1 by a transition fit, and the outer side of the upper bearing 9 is embedded in the upper bearing mounting groove 11; the inner side of the lower bearing 10 is connected to the stirring shaft 5 by a transition fit, and the outer side of the lower bearing 10 is embedded in the lower bearing mounting groove 12; at the connection position of the shaft and the bearing, the shaft diameter gradually decreases, and at the theoretical position of the bearing, the shaft diameter gradually exceeds the inner diameter of the bearing, so as to facilitate the transition fit between the shaft and the bearing and limit the bearing; the fastening ring 2 includes two semicircular fastening rings, the semicircular fastening ring Locking ears 15 are provided at both ends, and a step is provided at the inner diameter of the semicircular fastening ring. The step locks the upper part of the semicircular sleeve and is fastened by bolts. A gap is provided between the upper part of the step and the drive shaft 1 to prevent the fastening ring 2 from rubbing against the drive shaft 1; the flange 6 includes two semicircular flanges, an annular clamping block 13 is provided on the inner side of the semicircular flange, and an annular groove 14 is provided on the outside of the two semicircular sleeves. The annular clamping block 13 is installed in the annular groove 14, and the semicircular flange is installed on the mixing tank body 4 by bolts; the mixing tank body 4 is provided with a flange mounting groove, and the two semicircular flanges are installed in the flange mounting groove by bolts; two fixing blocks 7 are provided at intervals at the bottom of the drive shaft 1, and a plug-in block 8 is provided on the upper part of the mixing shaft 5. The plug-in block 8 is inserted between the two fixing blocks 7 and fixed by bolts and nuts. The rest is the same as Example 1.

[0026] When the stirring rod is working, the motor drives the stirring shaft 5 to rotate through the drive shaft 1, and then the stirring rod rotates as a whole. The drive shaft 1 and the stirring shaft 5 are fastened at the connection by two semicircular sleeves arranged on the outside. The bottom of the two semicircular sleeves is fixed on the stirring tank body 4 through two semicircular flanges. The top of the two semicircular sleeves is fastened by two semicircular fastening rings. The inside is connected by bearings to ensure the power transmission and rotation of the drive shaft 1 and the stirring shaft 5. It can also ensure that the stirring rod rotates concentrically up and down. At the same time, the stirring efficiency is not affected and is not disturbed by external forces. Due to the fixing effect of the semicircular sleeves and bearings, the stirring rod has a very small swing amplitude when working, which reduces the probability of the stirring rod and the stirring tank being scratched, ensuring the smooth operation of the stirring rod, thereby ensuring the quality of the glass liquid and the stability of the production process.
