The Main Difference Between The Key Bar And The Slat Type Air Shaft

What is the difference between a key bar type air expansion shaft and a slat type air expansion shaft?

The application range of the key bar type air expansion shaft includes: the key bar type air expansion shaft expands from a single key bar, the fulcrum spreads to each key bar, balances the force, and the air expansion shaft can be applied to articles with heavy mechanical load bearing capacity. For example: cloth, paper, film, printed matter, leather, composite materials, etc., suitable for coating, printing, rewinding, papermaking, plastics and other related machinery retractable reels, can effectively improve work efficiency.

The slat-type air-up shaft expands from the entire plate, and the fulcrum is evenly distributed, and the force is uniform. It can be used for high-precision mechanical or light-weight articles, such as: drying machine, flexo printing machine. , trademark printing machines, etc.

Other machinery: leather machine, setting machine, embossing machine, slitting machine, die cutting machine, paper tube machine, bag making machine, laminating machine, foaming machine, paper machine, cloth inspection machine, battery equipment, etc. Use of related machinery.

The key bar type air expansion shaft and the slat type air expansion shaft on the winding unwinding equipment must be relatively stable in the belt drive machine, so as to reduce the vibration and ensure the printing quality. The main technical requirement for belt drive is: correctly install the belt on the shaft without skewing and swinging. The assembled V-belt should be perpendicular to the axis of rotation of the pulley. The tension of the belt should be sufficient to ensure the contact between the belt and the pulley. There is enough friction on the surface to achieve high transmission efficiency.

The winding and unwinding equipment uses a V-belt to transfer the power of the motor into the machine. When repairing the key-type air-expanding shaft and the slat-type air-up shaft, the following inspection and adjustment should be performed on the belt-driven machine. The relative position between the pulleys is closely related to the working condition of the transmission on the inflatable shaft. Excessive offset will make the tension of the belt uneven and accelerate the wear of the belt. Therefore, for the pulleys moving to each other, during the maintenance process, it should be checked. Its relative position and adjustment is appropriate.

It can be seen that the key bar type air expansion shaft and the slat type air expansion shaft play a very large role in the winding and unwinding equipment.
