The pulp molded cup lid production line is composed of a pulping system, a host device, a vacuum system, a high-pressure water system and an air compressor system, and is used to produce disposable pulp molded cup lids. The production line uses sugarcane pulp, bamboo pulp, wood pulp, reed pulp, straw pulp and other pulp boards as raw materials, and it is prepared into a pulp with a certain concentration through the processes of hydrapulping, refining, adding chemical additives, etc. It is evenly attached to a special metal mold to form a wet blank product, and then a disposable pulp molded product is produced through the drying, hot pressing, punching and trimming, and stacking processes. The average production capacity of the host system is 100,000 pieces / day. And it can be customized per the actual situation of customers.
Pulp molding cup lid production line
The cup lid making machine can customize various types of lids, including hybrid lids, sipping lids, spill-proof lids, dome lids, and flat lids.
Paper Cup Lid Raw materials: Utilize renewable plant fiber resources such as bagasse, wheat straw, reed, moso bamboo and other plant fibers.
Production of Eco-Friendly Molded Fiber Packaging with Small Draft Angles: Our process allows for the creation of high-quality, eco-friendly molded fiber packaging with a draft angle of at least 0.5 degrees and radii of at least 0.3 mm. The prepress system is equipped to handle negative angles, ensuring high precision and positioning accuracy. This makes it easy to control and ensures stable operation, meeting the requirements of various types of packaging, including high-end products.

Working Process of Paper Cup Lid Making Machine
Pulping making system
In the pulping process, different proportions of plant fiber pulp cardboards are first placed into the pulper, where water is added and the mixture is broken down. This mixture is then processed into a cotton-like fiber thick slurry using a deflaking machine and a refiner as needed. The slurry is then transferred to the pulp mixing tank by a pulp pump. Based on the performance requirements of the molded pulp product, appropriate amounts of additives and water are added to the pulp mixing tank in a specific order and stirred thoroughly to prepare the required pulp for molding. The prepared material is then transferred to the slurry supply tank, ready to be transported to the molding machine.
Forming system
The forming die absorbs the slurry in the slurry pool to form a wet embryo. The upper die squeezes out the water for the first time and then moves the formed wet embryo to the hot pressing table for the second time. After hot pressing, the upper die absorbs the dried product and transfers it to the stacking table for manual quality inspection and then moves it to the automatic trimming machine. After trimming, the finished product is automatically stacked and counted, ready for final packaging.
Vacuum system
A vacuum system in a pulp molding line is essential for forming and dewatering processes, ensuring the efficient production of molded pulp products like Disposable paper tableware, high-end paper-plastic packaging, egg trays, fruit trays, and other packaging materials. This system involves several components that work together to create, maintain, and control the vacuum necessary for the pulp molding process.
Proper design, operation, and maintenance of the vacuum system are essential for optimal performance. Advances in automation, energy recovery, and sustainability are driving improvements in vacuum system technology, contributing to more efficient and environmentally friendly pulp molding operations.
Air-pressure system
Air compression systems are vital in the pulp molding production line, providing the necessary compressed air for various functions such as powering pneumatic equipment, controlling valves, and assisting in the drying and demolding processes. These systems ensure that the production line operates efficiently, reliably, and safely.
Proper design, operation, and maintenance of the air compression system are essential for ensuring the efficiency, reliability, and safety of the production process. Advances in automation, energy efficiency, and sustainability are driving improvements in air compression technology, contributing to more efficient and environmentally friendly pulp molding operations.
