The Valve Port Bottom Paste Machine is specially designed for the automatic lamination process of the valve bottom of multi-layer paper-plastic composite bags, which completely solves the problem of low efficiency in traditional paper bag production, which relies on manual plate changing. As China's first intelligent bottom pasting equipment, its core function is to complete the bottom indentation, gluing, forming and precise insertion of the valve port of the paper bag through a fully automatic process, achieving high-speed and stable production of 130-150 strips per minute, with a length error of only ±1mm and a width error of ±1mm for the finished product, meeting the strict requirements of the food, chemical and other industries for high-precision valve port packaging bags.
The equipment model is BM2022-1F, and the Valve Port Bottom Paste Machine adopts a modular design, which supports flexible adjustment of parameters such as paper bag size (length 360-900mm, width 320-580mm), valve port length (100-250mm), etc., and adapts to the production needs of multiple scenarios. By integrating patented technologies such as high-speed vacuum suction cup picking, intelligent abnormal rejection, and small S-shaped compaction mechanism, Desheng Intelligent has redefined the automation standards of the paper bag manufacturing industry and promoted the industry's transformation to high efficiency and low energy consumption.

| High-speed rotary vacuum suction pick-up → step arrangement (with abnormality rejection function) → center-to-center straight embossing, 45° oblique embossing (with piercing mechanism) → straight ear incision at bag opening → sucking open horns to unfold and smooth → valve Inserting at the mouth → embossing at the bottom, closing the bottom and applying glue → closing the bottom and forming → turning the bottom and compacting (with abnormal rejection) → small S compacting mechanism → counting and stacking output | |||
Food packaging field
Production of flour and sugar valve mouth self-supporting bags, PE film inner layer moisture-proof and leak-proof, FDA food grade certification, load-bearing up to 30kg.
Chemical raw material packaging
Customized corrosion-resistant PE composite bags, valve mouth sealing meets IP68 standards, suitable for powder and granular materials such as carbon powder and fertilizer, reducing filling dust.
Building materials and mineral packaging
4 layers of kraft paper + reinforced PE film structure, production of 50kg cement and quartz sand valve bags, 45° oblique embossing tear strength ≥ 1000N.
Environmentally friendly and recyclable packaging
Using bio-based glue and recycled paper, it provides "zero plastic" solutions for environmentally friendly brands and supports carbon footprint label printing.
Full-process intelligent control and high-precision production
AI visual positioning system: The valve insertion link uses a CCD camera for real-time positioning with an accuracy of ±0.2mm to ensure that the valve and the bag body fit seamlessly and the air leakage rate is reduced to less than 0.05%.
Dynamic deviation correction technology: The position of the paper bag is detected by a laser sensor during the step arrangement stage. If the deviation exceeds 0.3mm, the rejection mechanism is automatically triggered, and the scrap rate is less than 0.2%.
Ultra-high speed and continuous production
130-150 pieces/minute production capacity: 220% higher efficiency than traditional equipment, daily output reaches 200,000 pieces, and unit energy consumption is reduced by 40% (only 380V industrial voltage is required).
Uninterrupted coil supply: Equipped with an automatic tension control system, the roll change time is ≤2 minutes, and it supports 72 hours of continuous operation without stopping.
Multifunctional composite process integration
Multiple types of indentation and punching: synchronously complete center straight line embossing, 45° oblique embossing (enhanced tear resistance) and bag mouth straight ear incision, adapting to different bag structure requirements.
Dual-channel gluing technology: supports switching between hot melt glue (160℃±5℃) and environmentally friendly cold glue (water-based acrylic acid), glue quantity control accuracy ±0.08g, bonding strength ≥18N/cm².
Heavy-duty structure and long life design
30-ton integrated steel structure fuselage: using Q355B high-strength steel and robot welding technology, the seismic performance is improved by 50%, and the design life exceeds 12 years.
Core component import configuration: German Beckhoff PLC controller, Japanese SMC pneumatic components, mean time between failures (MTBF) ≥6000 hours.
Intelligent interaction and remote operation and maintenance
12-inch industrial-grade touch screen: preset 25 bag parameter templates, support one-key switching of production mode, real-time monitoring of energy consumption, output and fault codes.
IoT cloud management: Built-in 4G module, engineers can remotely diagnose device status and push firmware upgrades, reducing downtime by 85%.
Expanded advantages:
Environmental compatibility: compatible with degradable PLA film and FSC-certified recycled paper, in line with EU EN13432 and US ASTM D6400 environmental standards.
Quick mold change system: mold change time ≤ 10 minutes, supporting small batch multi-category flexible production (such as switching 5 bag types every day).
Daily cleaning and lubrication
Clean the residual glue in the glue tank after daily shutdown (special high-temperature resistant silicone scraper), and apply full synthetic grease (temperature resistant -30℃~180℃) to the guide rails and chains.
The vacuum suction cup cleans the air holes with isopropyl alcohol every week to prevent paper scraps from clogging and causing a decrease in suction.
Regular maintenance of key components
Check the wear of the servo motor carbon brush every month (threshold ≤2.5mm), calibrate the tension of the synchronous belt to 55-65N; add ISO VG68 high-speed lubricant to the bearings every quarter.
The photoelectric sensor is calibrated with a standard calibration plate every six months to ensure that the detection accuracy error is less than 0.1mm.
Consumables replacement and upgrade
The glue nozzle is replaced after every 600,000 pieces are produced (the original tungsten carbide nozzle is wear-resistant), and the life of the heating plate thermocouple is 2.5 years. Expiration may cause temperature control deviation of ±10℃.
The software system is upgraded every six months to obtain optimization algorithm and security protocol updates.
Fault emergency handling
Unsound gluing: Check the glue temperature (hot melt glue is recommended to be 160℃±3℃) or the parallelism of the pressure roller (tolerance ≤0.05mm).
Valve port offset: Restart the visual positioning system and recalibrate the reference point, and clean the fingerprint or dust on the camera mirror.
Long-term out-of-use protection
Discharge the residual pressure of the air path after disconnecting the power supply, spray WD-40 rust inhibitor on key metal parts, and cover them with anti-static dust covers; place a humidity indicator card in the control cabinet (threshold RH＜40%).
