Description

Technical Field

[0001] This utility model belongs to the field of transmission, specifically relating to a high-speed conveying device. Background Technology

[0002] During lead-acid battery plate production, electrode groups are conveyed to the next processing station via a conveyor system. To accommodate the varying electrode thicknesses in different types of lead-acid batteries, the spacing between the two clamps of the electrode group fixtures in the conveyor system needs to be adjusted accordingly. The current adjustment method involves manually loosening the fasteners (such as bolts and nuts) fixed to the conveyor chain and clamps, determining the position, and then tightening the fasteners on the clamps. Taking a conveyor system 4-5 meters long as an example, with 70 sets of clamps mounted on the conveyor chain, manually adjusting the spacing between the clamps takes half a day, which is time-consuming and labor-intensive. This severely impacts operational efficiency during product changeovers in assembly line production. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide a single-shaft dual-transmission mechanism that allows for convenient and quick adjustment of the distance between the two clamping plates without disassembling the clamping plates, thereby improving the efficiency of shape change.

The large and small internal splines together form the stepped internal spline.

[0032] The drive shaft is mounted on the frame via two bearing housings 404. The inner ring of one bearing housing is fixed to the outer casing of the outer shaft 413, and the inner ring of the other bearing housing is fixed to the outer coarse cylinder of the inner shaft 418.

On the one hand, it prevents axial movement of the inner sleeve shaft that may occur after the two shafts are disengaged by a manual clutch; on the other hand, it reduces the friction between the end of the outer sleeve shaft and other connecting components.

[0037] The inner shaft 418 is a stepped shaft, including a thin cylindrical portion at one end, a middle cylindrical portion in the middle, and a thick cylindrical portion at the other end.

The outer wall of the large gear 409 is an external spline one. The inner shaft 418 on the inner surface of the large gear 409 is fitted with an outer shaft 413 via a bearing 412. The outer wall of the outer shaft 413 near the end of the large gear 409 has an external spline two. External spline one and external spline two form a stepped external spline. The diameter of external spline one is larger than the diameter of external spline two. The other end of the inner shaft 418 has a drive gear 416. The inner shaft 418 is connected to the motor 406 via the drive gear 416 and the drive chain 403. The drive gear 416 is limited by the shoulder between the coarse cylindrical part and the middle cylindrical part. The drive gear 416 and the drive sprocket assembly are located between the two bearing seats 404. The drive gear 416, the drive sprocket assembly, and the bearing seats 404 are positioned by the spacer 405.

[0038] During the conveying process, the outer shaft 413 and the inner shaft 418 are in a connected state, and the stepped inner spline of the spline sleeve is fully connected with the stepped outer spline.

[0039] When product changeover is required, open the cover 4, push the handwheel 407 of the manual clutch assembly, and the spline sleeve moves axially along the drive shaft to the point where it is disengaged from the outer spline at one end of the inner shaft. The outer shaft is disengaged from the inner shaft, and the small inner spline of the spline sleeve is connected to the outer spline at one end of the outer shaft. Turn the handwheel 407, and the spline sleeve rotates. The outer shaft 143 rotates clockwise or counterclockwise with the spline sleeve, driving the adjusting sprocket 402 to rotate. The distance between the moving fork plate and the fixed fork plate on the first transmission chain increases or decreases. The inner shaft 418 remains fixed and does not rotate. After the spacing adjustment of the plate clamp is completed, release the handwheel 407. Under the thrust of the spring 411, the handwheel automatically resets, and the outer shaft 413 and the inner shaft 418 are connected. The stepped inner spline and the stepped outer spline of the spline sleeve are fully connected, and the pole group conveying operation can be carried out.
