Greenhouse Ventilation Rack and Pinion Rolling Forming Machine is design to make the greenhouse ventilation rack and pinion in batch fully automatically. 

Greenhouse Ventilation Rack and Pinion:

It is one of the automation systems for ventilation via motors with rack and pinion for the greenhouse system. Rack & pinions are available in many various configurations. Pinions are manufactured as an enclosed ‘clam shell’ housing to keep debris out and the mechanisms running free. Pinions are offered as a traditional one piece design or as a two piece unit (the EZ-fit) ideally suited to repairs and retro-fits.Reliable, low-maintenance Power Vent System includes durable rack and pinion setup for automated greenhouse ventilation across all zones.

Here are some drawing profiles and sample pictures for your reference:

Greenhouse Ventilation Rack and Pinion Rolling Forming Machine design:

This machine is composed by the following elements: Decoiler, punching system, main rolling forming machine, shearing system and receiving table. In order to save the cost, this machine is designed using hydraulic punching system, if you want to enhance the machine working speed, you can choose to use hydraulic press to punching the zigbag.

The machine working speed is around 5 to 7 meter per minute.

Where to use:

The pinion involves mainly one gear,one galvanized sheet house,and two copper alloy bearing.lts gear is made from the technology of powder metallurgy,and is quenched.The gear has hard surface,and is strong.The gear is located in a galvanized sheet house,and is supported by two copper alloy bearings.This pinion can be easily turned,and has long life time. lts maintenance is very easy.While running.the pinion makes almost no noise.
