Cement Valve Port Paper Bag Bottom Paste Machine is China's first intelligent production equipment designed specifically for the bottom sealing process of cement valve port paper bags, independently developed by Enping Desheng Intelligent Technology Co., Ltd. The core function of Cement Valve Port Paper Bag Bottom Paste Machine is to efficiently bond multi-layer paper-plastic composite materials (such as 2-4 layers of paper + 1 layer of PE film) through precise mechanical structure and intelligent control system, and complete key processes such as valve port insertion, bottom lamination, glue coating, etc., and finally output valve port paper bags that meet industrial-grade strength and sealing standards.
Unlike traditional equipment, Cement Valve Port Paper Bag Bottom Paste Machine adopts a modular design and can adapt to the production needs of paper bags of different sizes (bag length 360-900mm, bag width 320-580mm) and structures (multi-layer composite). It is especially optimized for the pressure resistance, moisture resistance and high-speed filling requirements of valve bags in the cement industry. Its technological breakthrough lies in the use of intelligent sensing and real-time correction systems to ensure the bag bottom bonding accuracy (error ±1mm) and valve port positioning stability, while supporting continuous coil feeding, greatly reducing the frequency of shutdowns for material changes, and becoming a landmark equipment for the cement packaging industry's transformation from semi-automation to full intelligence.

| 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 | |||
1. Mass production of valve bags in the cement industry
Designed specifically for cement filling, the valve bags produced can withstand a filling impact of more than 50kg, and the bottom bonding strength is ≥8N/cm, meeting the needs of high-speed assembly line operations.
2. Chemical powder packaging
Suitable for moisture-proof packaging of corrosive powders such as fertilizers and titanium dioxide. The PE film composite layer and the valve port sealing structure prevent the material from absorbing moisture and agglomerating.
3. Food-grade paper and plastic packaging
After replacing the food-grade glue and stainless steel contact parts, food valve bags such as flour and starch can be produced, and FDA food safety certification can be passed.
4. Special bags in the building materials industry
Support the production of thickened paper bags (such as gypsum board transport bags), and improve the puncture resistance by enhancing the bottom embossing depth (up to 2mm).
5. Export trade standard packaging
The equipment complies with the ISO 9001 quality management system, and the paper bags produced can pass the ISTA 3A transportation test to meet the stringent conditions of cross-border logistics.
1. High-efficiency production and precise control
High-speed continuous production: high-speed vacuum suction cup material picking technology, combined with a step-by-step arrangement system, achieves a stable output of 130-150 paper bags per minute, which is more than 50% more efficient than traditional equipment.
Precise size control: through servo motor drive and laser calibration system, the error control of bag length (±1mm), bag width (±1mm) and bottom width (±3mm) reaches the industry-leading level, ensuring seamless connection with the filling line.
Dynamic deviation correction function: in the 45° oblique embossing and straight embossing processes, the built-in infrared detection device monitors the material deviation in real time and automatically adjusts the pressing angle to avoid the increase in scrap rate due to material deformation.
2. Intelligent process integration
Multi-process integrated design: integrates more than 10 processes such as valve port insertion, bottom gluing, bottom folding and compaction, and realizes one-key parameter switching through the central control system (PLC+HMI interface) to reduce manual intervention.
Automatic rejection of abnormalities: Dual detection modules are configured in the step arrangement and bottom pressing links to automatically identify defects such as positioning errors and insufficient glue, and reject defective products in real time and alarm prompts.
Intelligent temperature control gluing: A constant temperature hot melt glue system is used to dynamically adjust the glue viscosity according to the ambient temperature and production speed to ensure uniform and stable bonding strength.
3. High stability structural design
Heavy frame structure: The weight of the whole machine is 30 tons, and the main body adopts a composite structure of thickened steel plate and aviation aluminum, with excellent vibration resistance and suitable for 24-hour continuous operation.
Modular maintenance design: Core components (such as vacuum suction cups and embossing rollers) use quick-release interfaces, and the replacement time is shortened to within 15 minutes, supporting online maintenance without affecting production.
Low energy consumption operation: Optimize the energy consumption of hydraulic and pneumatic systems, save 30% of electricity compared with similar equipment, and be equipped with waste heat recovery devices to reduce comprehensive operating costs.
4. Compatibility and scalability
Multi-material adaptation: It can process composite rolls of 2-4 layers of kraft paper and PE film, support various material combinations such as paper-plastic and full paper, and adapt to the needs of food, chemical and other industries by changing molds.
Flexible production mode: The Internet of Things (IoT) interface is reserved, and it can be connected to the MES system to realize cloud management of production data, leaving space for future intelligent factory upgrades.
5. Safety and environmental protection features
Enclosed protective cover: Key moving parts are equipped with transparent dust covers, which have both operational safety and noise isolation functions (≤75dB).
Environmentally friendly glue compatibility: It supports water-based environmentally friendly glue and bio-based hot melt glue, complies with EU REACH regulations, and helps companies pass green certification.
1. Daily maintenance
Cleaning procedures: Use a dust-free cloth to clean the residual glue in the glue tank after daily shutdown, and use a vacuum cleaner to remove dust from the transmission chain every week.
Lubrication cycle: Fill the gear set with food-grade lithium grease every 500 hours, and replenish the linear guide with high-speed lubricating oil every month.
2. Maintenance of key components
Vacuum suction cup: Check the wear of the silicone suction nozzle every quarter. If the thickness is less than 2mm, it must be replaced immediately to avoid material deviation.
Embossed roller: Disassemble the polished surface every 2000 hours to prevent the accumulation of glue on the pattern from affecting the clarity of the pressing.
3. Intelligent system maintenance
Sensor calibration: Use a standard calibration block to calibrate the sensitivity of the photoelectric sensor every month to ensure detection accuracy.
