Disposable coffee cups are often used to store hot drinks and require more sealing, roundness, structural strength and appearance flatness than regular paper cups. Whether coffee cup production equipment can produce high-quality commercial paper cup stably and reliably depends on its mature and precise automatic molding process. Different from the simple forming method of traditional paper cup machine, the special molding process of coffee cup has been optimized according to hot beverage usage scene, the demand of color printing and batch standardized production, so as to effectively solve common problems of paper cup leakage, deformation, bad curl and pattern misalignment. This paper describes the core characteristics and industrial application value of coffee cup manufacturing machine forming process.
coffee cup machine adopts integrated continuous molding process, full automatic closed-loop operation, which is the core technology characteristic of coffee cup machine. The whole molding process includes six steps: precision paper feeding, mold roll forming, cup body bonding, cup bottom stamping, cup rim rolling, automatic unloading. Each workstation synchronizes through the servo system, guarantees the steady rhythm and smooth connection. Traditional cup-making equipment technology is scattered, synchronicity is poor, mechanical error is easy to occur in the molding process, resulting in poor consistency of the finished product. The coffee cups special molding process realizes ``single-use molding, full process molding '', does not need the second processing, fundamentally improves the regularity and production efficiency of paper cups, adapts to large-scale standardized mass production.
High-precision die rolling process ensures that the cup body is round, symmetrical, free of distortion and offset. Coffee cup belongs to conical paper cups, which requires extremely high curvature. Even minor deviations can lead to cup tilting, unstable placement and lag in filling equipment. The device is equipped with custom-made high-precision curved die with high adhesion and uniform force. Paper rolling process smooth and smooth, no local squeezing, wrinkling, stretching and deformation. Especially suitable for the production of color printing cup paper, the shape of the design is correct, uniform position, no distortion or dislocation, greatly improved the appearance and texture of customized coffee cups, in line with the brand tea and coffee chains's high-end packaging standards.
Suitable for the use of hot drinks scene of a variety of sealing and bonding technology is the key technology of coffee cup molding highlights. The device supports two main processes, thermal press bonding and ultrasonic bonding, and can be switched flexibly according to product quality requirements. Thermal press bonding adopts the method of constant temperature and high temperature fusion, which makes the interface of cup body fast and stable. It is suitable for traditional coffee cups production. Ultrasonic bonding does not require high temperature, but can be achieved by high frequency vibration. The seams are smooth, have no carbon deposits or odour, and have high bonding strength. It is suitable for the production of high grade food coffee cup, and avoids problems of glue cracking and water leakage when filling hot drinks.
The high-pressure compaction molding process at the bottom of the paper cup greatly improves the leak proof and pressure bearing ability of the paper cup. Ordinary paper cup machine accessories are loose, the pressure of the bottom of the cup is uneven, easy to seep water after filling with hot water, the bottom of the cup is easy to fall off. coffee cup machine adopts special cup stamping structure, pressure balance is stable. The bottom of the cup clings to the cup and compacts evenly. After forming, the bottom of the cup is smooth, strong, good pressure resistance, strong sealing. Long-term high temperature water vapor penetration, thoroughly solved the industrial hot drink paper drink paper cups water leakage common problems, greatly improved the safety and stability of finished product use.
Improve the roll forming process and optimize the strength and feel of the cup structure. Cups are the core of paper cup that come into contact with drinks under pressure. The special rolling mechanism of this equipment can achieve uniform internal rolling forming, round cup mouth, uniform thickness, no burrs, no gap. Curling can not only improve drinking comfort, but also enhance cup structure, prevent paper cups from softening, deforming and curling after serving hot drinks, and make the finished coffee cup more durable. It is also suitable for automated sealing and filling equipment.
From the point of view of industry value, this professional molding process is completely different from ordinary simple cup making process. It not only achieves the high precision, high sealing and high consistency of coffee cups, but also greatly reduces the defect rate, minimizes the loss of raw materials and improves production efficiency. Stable molding quality ensures the safety and conformity of coffee cups produced, making the mugs suitable for high-end business scene, helping packaging factories to improve product competitiveness and meet the refined and branded packaging production needs of the beverage industry. It is the core process guarantee to improve the quality and efficiency of modern paper cup production line.
