500mm-1500mm Machine Stretch Hood Film Hydraulic Stretch Hooder Equipment

This full-automatic gantry stretch hood machine is professionally developed and customized for supporting dry mortar, tile adhesive, putty powder and building powder automatic production lines. Matched with robot palletizer and roller conveying line, it adopts cold stretch film wrapping technology without high-temperature heating treatment. The equipment automatically completes film unwinding, constant tension stretching, top-down hood covering, bottom heat sealing and film cutting, realizing 5-sided integrated sealed packaging for palletized mortar stacked goods. It supports full-line automatic docking with bagging machine, palletizer and stereoscopic warehouse, replaces traditional manual winding film and heat shrink packaging, realizes unmanned packaging operation for finished mortar products, and improves packaging efficiency and cargo storage and transportation protection performance.

• Powder Workshop Safety Design: Pure cold stretch working mode, no heating furnace, no high temperature ignition risk. Effectively avoid dust explosion hidden dangers in closed mortar production workshops, fully meet factory fire protection and safety production standards.
• Full-surface Sealed Protection: Realize one-piece wrapping for the top and four sides of pallet goods. Features excellent waterproof, dustproof, moisture-proof and anti-corrosion performance, preventing mortar bag caking, powder leakage, rain erosion and sea salt corrosion during long-distance transportation and outdoor stockpiling.
• Highly Intelligent Automatic Operation: Equipped with PLC touch screen control system and photoelectric height sensor. Automatically detect stack height, adjust stretching stroke intelligently, finish film feeding, covering, sealing and cutting automatically. No frequent manual parameter adjustment, easy linkage with the whole mortar production line.
• Low Packaging Consumption & Cost Saving: High elastic PE cold stretch film fits tightly with material pallets by retraction force. Film consumption is 30% lower than traditional winding film. Equipped with large-capacity film roll holder, reduce film replacement frequency and labor workload.
• Heavy-duty & Durable Structure: Thickened gantry steel frame, dual servo drive and heavy-load roller conveyor. Adapt to 24-hour continuous heavy-load operation of building material factories, anti-deformation, long service life, low failure rate.
• Complete Safety Protection System: Equipped with safety isolation fence, infrared grating protector, global emergency stop button and fault alarm system. The machine stops automatically once people or foreign objects enter the working area to ensure on-site operation safety.

• Keep the workshop ventilated and dry, clean floating mortar powder on guide rails, sensors and rollers regularly per shift to avoid sensor failure and mechanical jamming.
• Cut off the total power supply before replacing film roll or conducting equipment maintenance, and hang warning signs to avoid accidental startup.
• Operate film threading strictly according to standard drawings to prevent film deviation, edge tearing and incomplete bottom sealing.
• Prohibit personnel from entering the internal working area of safety fence during machine running.
• Check chain tightness, circuit aging and grating sensitivity before daily startup; stop operation immediately once abnormal noise or mechanical failure occurs.
• Lubricate transmission chains and rotating rollers regularly; replace worn sealing blades regularly to guarantee sealing effect.
• Store PE stretch film in cool and dry warehouse, avoid long-term sunlight exposure, which will reduce film stretch toughness.
• Do not modify internal electrical programs and servo parameters without professional technical guidance.

• Dry Mortar Processing Factory: Automatic hood packaging for palletized masonry mortar, self-leveling mortar, waterproof mortar, tile adhesive and interior wall putty powder.
• Building Material Powder Industry: Sealed packaging for 20-50kg valve-port bag products such as gypsum powder, grouting material and cement compound powder.
• Export Building Material Enterprises: Cargo packaging for sea freight, cross-border long-distance truck transportation, adapt to humid and high-salt overseas transportation environment.
• Automatic Intelligent Warehouse: Docking with AGV trolley, automatic palletizer and stereoscopic warehouse to realize full-process unmanned logistics packaging.
• Outdoor Temporary Stockyard: Prevent bagged mortar goods from getting damp, polluted and damaged in outdoor open-air storage environment.

Q1: What is the difference between stretch hood machine and heat shrink wrapping machine?

A: The stretch hood machine adopts normal-temperature cold wrapping without heating, zero dust combustion risk, lower power consumption, more suitable for mortar powder workshops. Heat shrink machine needs high-temperature heating, which has explosion risk facing floating mortar dust, not recommended for powder production lines.

Q2: Can this machine connect with my existing mortar palletizing line?

A: Yes. We support customized size, conveying height and reserved signal interface, compatible with most mainstream automatic palletizers and roller conveying lines on the market.

Q3: Why choose stretch hood packaging instead of manual winding film?

A: Manual winding cannot cover the top of goods, leading to easy damp mortar bags. This machine realizes 5-sided full sealing, saves 30% film cost, and improves packaging efficiency greatly without manual operation.

Q4: How many workers are required for daily operation?

A: Only one worker is needed for regular film replacement and daily equipment inspection. The whole wrapping process runs automatically without full-time monitoring.

Q5: Can the machine adapt to mortar stacks with different heights?

A: Yes. Equipped with high-precision photoelectric sensor, it automatically identifies stack height and adjusts working stroke intelligently without manual setting.

Q6: How to solve film tearing during wrapping?

A: Check offset film roll, clean sharp burrs on sealing cutter, and reduce servo stretching tension on the touch screen properly. We provide special high-toughness stretch film for mortar industry.

Q7: What about the after-sales warranty service?

A: The whole machine enjoys 1-year warranty for man-made excluding parts; core servo motor, PLC and electric parts enjoy 2-year warranty. We provide remote debugging and overseas on-site installation and training service.
