product description

1. Product Overview

This Greenhouse Lock Channel Cold Roll Forming Machine is a fully automatic continuous forming equipment specially designed for producing greenhouse film lock channels, also known as greenhouse card troughs. It processes galvanized steel strips, color steel coils and other metal raw materials into standard U-shaped lock troughs in one continuous procedure, widely matched with multi-span greenhouses, solar greenhouses, vegetable planting greenhouses and agricultural seedling greenhouses.

Integrated with automatic feeding, multi-pass rolling forming, hydraulic cutting and PLC intelligent control, the whole line realizes unmanned continuous production. The finished lock channel has uniform wall thickness, stable dimensional tolerance, high straightness, and excellent bending resistance, which can firmly fix greenhouse plastic film, sunshade net and insect-proof net, effectively preventing wind blowing and film shedding.

2. Core Structural Advantages

1. Heavy-Duty Forming Frame & Forming Roller Groups The machine base adopts thickened integral blue steel plate welding, with high rigidity and no vibration during long-time high-speed operation. Multiple groups of precision forming rollers are made of high-quality forged steel with hard chromium plating treatment, wear-resistant and long service life, ensuring consistent forming effect for thousands of tons of raw materials. Each roller station is equipped with independent adjustment structure, convenient for fine-tuning product width and radian.
2. PLC Touch Screen Intelligent Control Cabinet Equipped with independent vertical electrical control box with touch screen human-machine interface. Operators can set product length, production quantity, running speed and cutting parameters directly on the screen. It supports automatic counting, fault alarm, one-click start/stop and emergency stop protection, greatly lowering operation threshold and reducing manual errors.
3. Hydraulic Quick Cutting System Independent hydraulic station with high-power hydraulic motor, matched with yellow hydraulic cutting head. The cutting process is fast and burr-free, without deformation of the finished lock channel section. The flying cut design avoids production pause during cutting, realizing non-stop continuous forming and cutting to greatly improve production efficiency.
4. Precision Feeding & Positioning Mechanism Front-end feeding guide device with threaded horizontal positioning slide rail, which can automatically calibrate steel strip deviation to avoid finished product distortion caused by raw material offset. The yellow safety protection cover at the feeding end prevents accidental contact with running steel strips, meeting international CE safety standards.
