Valve Port Paper Bag Bottom Paste Machine is China's first intelligent paper bag production equipment developed by Enping Desheng Intelligent Technology Co., Ltd. It is specially designed for the valve port bottom laminating process of multi-layer paper-plastic composite bags (such as 2-4 layers of paper + 1 layer of PE film), which completely revolutionizes the industry pain points of relying on manual plate changing and low efficiency in traditional paper bag production. The equipment model BM2022-1F integrates high-precision positioning, intelligent detection and fully automatic production. Through vacuum suction cup picking, center alignment indentation, valve port insertion, bottom gluing and molding and other full-process automated operations, it can achieve high-speed and stable production of 130-150 paper bags per minute. The length error of the finished product is only ±1mm, and the width error is ±1mm, which meets the high standard requirements of valve port packaging bags in the food, chemical, building materials and other industries.
As a breakthrough product in industry technology, its core value lies in replacing traditional manual intervention with intelligent control systems (such as abnormal rejection and automatic deviation correction), which greatly reduces production costs and scrap rates. The equipment adopts a modular design, supports flexible adjustment of parameters such as paper bag length (360-900mm), width (320-580mm), and valve length (100-250mm), and adapts to production needs in multiple scenarios. Desheng Intelligence relies on its independently developed 45° oblique embossing technology, small S-shaped compaction mechanism and other patented processes to promote the intelligent and efficient upgrading of the paper bag manufacturing industry.

| 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 industry
Production of flour and sugar valve mouth self-supporting bags, bottom embossing to enhance load-bearing capacity (up to 25kg), PE film inner layer moisture-proof and leak-proof, FDA food contact certification.
Chemical raw material packaging
Customized corrosion-resistant PE film composite bags, valve mouth sealing up to IP67 standard, suitable for filling of powdery and granular materials such as carbon powder and fertilizer, reducing dust pollution.
Building materials and mineral packaging
4 layers of kraft paper + reinforced PE film structure, production of 50kg grade cement and quartz sand valve bags, 45° oblique embossing to enhance tear strength (≥800N).
Full-process intelligent production system
High-precision stepping arrangement and abnormal rejection: The position of the paper bag is monitored in real time by photoelectric sensors, and the rejection mechanism is automatically triggered when the deviation exceeds 0.5mm, reducing the scrap rate to less than 0.3%.
AI visual correction technology: The valve insertion link adopts CCD camera positioning with an accuracy of ±0.2mm to ensure seamless fit between the valve and the bag body.
High-efficiency production and energy-saving design
130-150 pieces/minute ultra-high-speed production capacity: 200% more efficient than traditional equipment, 180,000-200,000 paper bags can be produced daily, and unit energy consumption is reduced by 35% (only 380V standard industrial voltage is required).
Continuous coil supply system: supports uninterrupted feeding, coil change time ≤ 3 minutes, with automatic tension control to avoid material stretching and deformation.
Multifunctional composite process integration
Multiple types of indentation and punching: synchronous completion of center linear embossing, 45° oblique embossing and bag mouth straight ear incision, adapted to different bag structure requirements; punching mechanism can customize the aperture (1-5mm).
Dual-mode gluing technology: hot melt glue and cold glue dual channel switching, intelligent glue amount adjustment (error ±0.1g), ensure the bottom bonding strength ≥15N/cm².
High-strength structure and durability
30-ton heavy-duty fuselage frame: welded with Q345B high-strength steel, anti-seismic and anti-deformation, suitable for 24-hour continuous operation, and designed life of more than 10 years.

Expanded advantages:
Environmental compatibility: Adapt to degradable PLA film and recycled paper materials, in line with EU EN13432 packaging environmental protection standards.
Quick mold change design: mold replacement time ≤ 15 minutes, supporting small batch and multi-category flexible production.
Environmentally friendly recyclable packaging
Adopt FSC-certified recycled paper and bio-based glue to provide "zero plastic" valve bag solutions for environmentally friendly brands, supporting carbon footprint traceability.
Cross-border logistics customization
Adjust the bag size according to customer needs (such as 900mm long bags to adapt to European pallet standards), laser print batch codes and logistics labels to improve supply chain efficiency.
Daily cleaning and lubrication
Clean the residual glue in the glue tank after daily shutdown (special silicone shovel), and apply lithium-based grease to the guide rails and chains (temperature resistant -20℃~150℃).
Clean the vacuum suction cup with alcohol cotton pads every week to prevent paper scraps from clogging the pores.
Regular maintenance of key components
Check the wear of the servo motor carbon brush every month (threshold ≤3mm), adjust the tension of the synchronous belt to 50-60N; add high-speed lubricating oil to the bearing every quarter.
The photoelectric sensor is calibrated every six months to ensure detection accuracy.
Replacement and upgrade of consumables
The glue nozzle is replaced after every 500,000 pieces are produced (the original ceramic nozzle is corrosion-resistant), and the life of the heating plate thermocouple is 2 years. Expiration is prone to temperature control deviation.
The software system is upgraded once a year to obtain the latest production optimization algorithm and security patches.
Emergency handling of faults
Unsound gluing: Check the glue temperature (hot melt glue is recommended to be 160℃±5℃) or the flatness of the pressure roller, and calibrate it to within a tolerance of 0.1mm.
Valve port offset: Restart the visual positioning system and recalibrate the reference point, and clean the camera mirror stains.
Long-term out-of-use protection
Discharge the residual air pressure in the air pipe after disconnecting the power supply, spray anti-rust oil on key metal parts, and cover the dust cover; the control panel has a built-in desiccant to prevent moisture.
