Temperature Control Accuracy Heating Tube For Cup Paper Machine

Paper Cup Machine Heating Tubes

Paper cup machine heating tubes are core heating elements used in paper cup production equipment (such as cup forming machines and cup gluing machines) to heat, shape, and bond paper. Their performance directly impacts cup forming quality (such as bond strength and cup body flatness) and production efficiency. The following provides a detailed introduction to their core functions, classifications, key technical parameters, selection considerations, and maintenance:

 Key Technical Parameters: Core Indicators for Selection and Performance Evaluation
When selecting heating tubes for paper cup machines, focus on the following six parameters to ensure they match your equipment needs:

1.  Rated Power (W): This determines the heating speed and heat output and should be matched to the cup size (e.g., 9-ounce, 12-ounce) and production speed (e.g., 60-120 cups/minute). Higher production speeds require higher power (typically, a single heating tube has a power rating of 500W-2000W, with multiple tubes used in combination). 2. Rated Voltage (V): Must match the paper cup machine's power supply system. Common specifications are 220V (single-phase) or 380V (three-phase). Voltage mismatches can result in reduced heating efficiency or component burnout.

2. Operating Temperature Range: Paper cup production requires a controlled temperature range of 80°C-220°C (the melting temperature of the PE coating is approximately 110°C-160°C). The heating tube must be temperature-adjustable, and a safety margin must be provided for the maximum temperature to prevent overload.

3.  Tube Diameter and Length (mm): Determined based on the space available for the paper cup machine's heating station. For example, the cup body heating tube typically has a diameter of 8mm-12mm and a length of 150mm-300mm. Due to space constraints, the cup mouth shaping tube typically has a diameter of 5mm-8mm.
4.  Surface Material:
For contact heating (e.g., cup body bonding), choose 304/316 stainless steel (resistance to PE residue and easy cleaning).
For non-contact radiation (e.g., cup rim), choose high-purity quartz glass (excellent light transmittance and high thermal radiation efficiency).
5.  Temperature Control Accuracy: High-quality heating elements should maintain a temperature control accuracy of ±1°C to ±3°C to prevent poor bonding or paper damage due to temperature fluctuations.
