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.
