Description

Aluminum parting strip synchronous belt fixed-length traction conveying device

Technical Field

The utility model belongs to the technical field of hollow glass equipment, and particularly relates to a fixed-length traction conveying device for an aluminum parting strip synchronous belt

Background

With the domestic development of hollow glass technology, aluminum parting bead framing is increasingly widely applied. The aluminum parting strip framing equipment generally comprises an aluminum parting strip fixed-length conveying device, and the fixed-length conveying device determines the dimensional accuracy and the efficiency of the aluminum parting strip fixed-length framing. Most aluminum parting strip fixed-length conveying devices adopt a structural mode that an upper synchronous belt and a lower synchronous belt clamp and pull aluminum strips and convey the aluminum strips to a fixed length. However, the existing synchronous belt conveying device still has certain defects when in use. 1. The upper and lower synchronous belts clamp the aluminum strips, and are completed by applying pressure to one sides of the upper and lower synchronous belts with teeth by an upper pressing plate and a lower pressing plate. The pressing plate and the tooth surface of the synchronous belt have larger friction force, so that a motor with larger power and a speed reducer are required to be used as power output. This friction also makes the timing belt more susceptible to fatigue failure due to the higher tensile loads. The pressing plate rubs the tooth surface of the synchronous belt to enable the belt teeth to be worn, the service life of the synchronous belt can be reduced, and the phenomenon of tooth jump easily occurs when the abrasion is serious.

2. The adopted transmission mode is as follows: the motor power is firstly transmitted to the lower synchronous pulley group and then is transmitted to the upper synchronous pulley group from the lower synchronous pulley group through a pair of meshed gears. The transmission mode can limit the opening and closing clearance of the upper synchronous belt and the lower synchronous belt to the center distance of the two meshing gears and cannot be excessively large. So that the upper timing belt runs later than the lower timing belt. The load born by the lower synchronous belt is larger than that borne by the upper synchronous belt during operation, and the expansion and contraction amount of the upper synchronous belt is smaller than that of the lower synchronous belt in microcosmic. In addition, in order to adapt to the action of pressing and loosening of the upper pressing plate, the upper synchronous belt adopts a tensioning mode of variable elastic tensioning; the lower pressing plate does not need to act, and the lower synchronous belt adopts a tensioning mode of 'fixed tensioning'. The two different tensioning modes can also lead to different expansion and contraction amounts of the upper synchronous belt and the lower synchronous belt during operation. The upper synchronous belt is lagged behind the lower synchronous belt and the upper synchronous belt and the lower synchronous belt are different in expansion and contraction amount during operation, and the two microscopic phenomena can cause the relative sliding of the upper surface and the lower surface of the aluminum strip and the conveying surface of the upper synchronous belt and the lower synchronous belt, so that the abrasion of the conveying surface of the synchronous belt is accelerated, and the fixed-length conveying precision of the aluminum strip is reduced.
