product description

Our greenhouse rack gear cold roll forming machine is a fully automatic continuous forming equipment specially developed for producing galvanized greenhouse rack gears, widely applied in agricultural greenhouse shading, ventilation and lifting drive systems. This integrated line completes uncoiling, leveling, continuous cold bending forming, servo fixed-length cutting and finished product output in one go, realizing high-efficiency one-step molding of toothed rack profiles for greenhouses.

Different from segmented processing equipment, this cold roll former adopts multi-group precision forming roller stations with hard chromium plating treatment, ensuring uniform tooth shape, stable profile size and high straightness of finished greenhouse racks. It is compatible with hot-dip galvanized steel strip, pre-galvanized coil and other raw materials, perfectly matching the anti-rust demand of outdoor agricultural greenhouse accessories.

Core Working Process

1. Uncoiling & Feeding: Equipped with automatic passive uncoiler to stably deliver galvanized steel strip without deviation
2. Leveling Unit: Multi-roller leveling structure eliminates sheet warping to guarantee flat raw material
3. Cold Roll Forming Section: Arranged with dozens of precision forming roller groups, gradually extrudes the U-shaped base and integrated toothed edge of greenhouse rack step by step; each roller base uses cast iron annealing structure to reduce deformation during long-time operation
4. Servo Tracking Cutting System: High-speed hydraulic flying shear with servo encoder real-time length tracking, cuts finished rack without stopping the machine, zero material waste, cutting tolerance controlled within ±0.5mm
5. Finished Product Receiving Table: Automatic stacking support, neatly collects formed greenhouse rack gears for direct packaging and delivery

Key Technical Advantages

1. Ultra-stable Forming Precision All forming rollers are processed by CNC lathe and surface hard chrome plated, wear-resistant and long service life. The toothed profile of finished rack is consistent, meshing smoothly with greenhouse drive pinions, no jamming during greenhouse window opening & closing.
2. Full Automatic Intelligent Control Adopts PLC touch screen integrated control system, supports one-click parameter setting of rack width, thickness, production length and batch quantity. Real-time display of running speed, output count and fault alarm, one operator can manage the whole production line, greatly cutting labor cost.
3. Heavy-Duty Durable Structure Machine base uses thickened integral welded steel plate, stress relief annealing treatment to avoid frame vibration during high-speed operation. Main drive system equips high-power reducer and frequency conversion motor, stable power output, continuous 24-hour industrial operation available.
4. Wide Raw Material Compatibility Supports galvanized steel strip with thickness 0.8mm–2.0mm, adjustable forming mold to produce multiple specifications of greenhouse rack gears, meets the production demand of multi-size agricultural greenhouses.
5. Low Maintenance & Long Service Life Transmission parts use sealed lubrication design, roller stations equipped with independent oil filling ports; vulnerable spare parts are standardized for easy replacement, overall equipment service life reaches over 10 years under normal maintenance.

Finished Product Application

The rack gear produced by this cold roll forming machine is the core transmission accessory for agricultural greenhouses, mainly used in:

• Greenhouse external sunshade system drive mechanism
• Greenhouse internal thermal insulation film rolling system
• Greenhouse side window & top ventilation window opening system
• Hydroponic greenhouse lifting cultivation frame transmission parts

Galvanized finished racks have excellent anti-corrosion performance, suitable for high humidity, acid and alkali greenhouse environment, effectively extending the service life of greenhouse drive equipment.
