Stable Structure Paper Pile Turner Paper Stack Flipper Easy Maintenance

The paper pile turner (paper stack flipper) is an automated paper pile processing equipment specially designed for the printing and packaging industry, integrating six functions: flipping, dust removal, paper loosening, paper aligning, drying and static elimination. Driven by hydraulic or servo systems, the equipment realizes 180° automatic flipping of paper piles. Combined with a high-pressure air blowing + vibration paper sorting system, it quickly removes paper scraps and spray powder, loosens sticky paper, aligns the edges of paper piles, accelerates ink drying, and prevents paper sticking and smudging.

Suitable for various paper materials such as PS plates, coated paper, cardboard and corrugated paper, it is widely used in prepress paper sorting, double-sided printing paper turning and post-press drying and finishing. It can replace manual paper turning, improve efficiency by more than 80%, reduce labor intensity, and increase the qualification rate of printed products and the service life of printing machines.

• Multi-Paper Compatibility: Applicable to thin paper, thick cardboard, corrugated paper and laminated paper without damaging paper edges.
• Safety Design: Equipped with photoelectric protection, emergency stop and overload protection for safe operation.

3. Energy Saving and Easy Maintenance
•Circulating Air Blowing: Adjustable air volume, saving energy by more than 30%.
• Quick-Disassembly Structure: Filter elements, rubber rollers and air nozzles are easy to disassemble and clean, convenient for maintenance.
• Low Failure Rate: Imported electrical components with long service life and few failures.

4. Cost Reduction and Efficiency Improvement
• Reduce Labor: 1 set of equipment replaces 3–5 workers, saving more than 100,000 yuan in annual labor costs.
• Improve Printing Efficiency: Improved paper cleanliness increases printing machine speed by 3–5%.
• Reduce Loss: Reduce paper sticking and smudging, increasing the yield by 2–3%.
• Extend Equipment Service Life: Reduce impurities entering the printing machine and lower maintenance costs.

How to choose:

1. Match Production Capacity and Paper Material
• Daily Production Capacity: Choose semi-automatic models for small factories (<50 piles/day); fully automatic models for medium-sized factories (50–200 piles/day); high-speed + online models for large factories (>200 piles/day).
• Paper Pile Specifications: Select models according to maximum paper width (1300/1450/1650mm), maximum height (1350/1600mm) and maximum load capacity (1000/1800kg).
• Paper Type: Choose gentle models for thin paper; heavy-duty hydraulic models for thick cardboard/corrugated paper; scratch-resistant models for laminated paper.

2. Core Configuration Priority
• Driving System: Prioritize servo motor + hydraulic system (precise flipping, stable operation, low noise); pure hydraulic system is optional if budget is limited.
• Control System: PLC + touch screen, supporting formula storage, fault alarm and automatic counting.
• Processing System: Four-in-one system of high-pressure air blowing + vibration paper sorting + static elimination + hot air drying for more comprehensive functions.
• Safety and Environmental Protection: Equipped with safety doors, photoelectric protection and filter element filtration, meeting environmental protection requirements.

3. Brand and After-Sales Service
• Prioritize professional brands such as Changrong, Yuanchuang, SMH and WYLONG, which guarantee stability and spare parts supply.
• Inspect local after-sales service, response speed and the price of wearing parts (filter elements, rubber rollers and air nozzles are consumables).

4. Budget and Cost Performance
• Semi-automatic: 20,000–50,000 yuan; Standard fully automatic: 50,000–120,000 yuan; High-speed heavy-duty: 120,000–250,000 yuan.
• Calculated by annual processing piles × labor cost per pile, the investment payback period is usually 8–15 months.

How to use:

1. Pre-Startup Preparation
• Check the power supply, air source and hydraulic oil to ensure normal operation.
• Set parameters: flipping speed, air blowing pressure, vibration intensity, drying temperature (40–60℃).
• Clean the workbench, splints and air nozzles to remove paper scraps.

2. Operation Steps
•  Paper Loading: Place the paper pile steadily on the splint, align with the stop gauge, and ensure no deviation or protrusion.
•  Clamping: Start clamping, ensure the splint is evenly stressed without damaging the paper edges.
•  Operation: Press the start button, and the equipment automatically completes the full process of flipping → air blowing dust removal → vibration paper aligning → drying → splint loosening.
4. Paper Taking: After the process is completed, take out the paper pile and check the quality.

3. Daily Maintenance (Key)
• Daily: Clean the workbench, air nozzles and splints; check the hydraulic oil level and air source pressure.
• Weekly: Clean the air blowing filter elements; check the vibration parts and transmission chains, and add lubricating oil.
• Monthly: Calibrate the splint pressure and flipping angle; check the electrical circuits and sensors.
• Quarterly: Replace hydraulic oil and filter elements; deeply clean the internal air ducts and vibration system.

Q1: Paper pile flipping is skewed and uneven

Cause: Uneven splint pressure, misaligned stop gauge, loose paper pile, insufficient vibration.

Solution: Adjust the splint pressure, calibrate the stop gauge, pre-straighten the paper pile, and increase the vibration intensity.

Q2: Poor dust removal effect, residual paper scraps

Cause: Low air blowing pressure, blocked filter elements, offset air nozzles, insufficient air volume.

Solution: Increase the air blowing pressure, replace the filter elements, calibrate the air nozzles, and clean the air ducts.

Q3: Paper sticking, slow drying

Cause: Low drying temperature, small air volume, too thick paper pile, undried ink.

Solution: Increase the drying temperature (50–60℃), increase the air volume, process in separate piles, and extend the drying time.

Q4: Equipment stuck, weak flipping

Cause: Insufficient/deteriorated hydraulic oil, motor failure, worn transmission parts, overload.

Solution: Replenish/replace hydraulic oil, check the motor, replace worn parts, and reduce the weight of the paper pile.

Q5: Loud noise, abnormal vibration

Cause: Loose frame, lack of oil in transmission parts, damaged bearings, unstable foundation.

Solution: Tighten the frame, add lubricating oil, replace bearings, and reinforce the foundation.

Q6: Fault alarm (overload/overtemperature/low oil level)

Cause: Overweight paper pile, excessive temperature, low hydraulic oil level, sensor malfunction.

Solution: Reduce the weight of the paper pile, lower the temperature, replenish hydraulic oil, and calibrate/replace the sensor.
