Maximize Production with Sleeve Labelling Machine The Ultimate
Labeling Solution
As a core achievement of our company's technological innovation in
packaging automation, the SPC-550 next-generation single-head
sleeve labeler has completed R&D and achieved
industrialization. Addressing the pain points of traditional sleeve
labelers—including high-speed operational stability, safety
protection reliability, and multi-product adaptability—this
equipment undergoes comprehensive performance upgrades through
multiple customized designs and precision manufacturing processes.
It delivers efficient, durable, and safe sleeve labeling solutions
for bottled/canned product packaging lines across food, beverage,
daily chemical, and pharmaceutical industries.
I. High-Speed Stable Operation with Significantly Extended Service
Life
Centered on “high-efficiency continuous production,” the SPC-550
achieves balanced speed and stability through triple-tiered
technical safeguards: First, the core transmission system employs
multiple high-precision servo motors across three critical modules:
film feeding, positioning, and heat shrinking. Integrated with
closed-loop feedback control technology, it enables real-time
calibration of operational parameters. This ensures shrink film
maintains dimensional accuracy within ±0.1mm during conveyance,
completely eliminating label misalignment and wrinkling caused by
film deviation. Second, to address mechanical wear at high speeds,
critical components (such as transmission gears, guide shafts, and
clamping mechanisms) are constructed from high-strength aerospace
alloy materials. These undergo surface nitriding hardening
treatment and are integrated with a sealed automatic lubrication
system. This reduces component wear rates by over 60%, extends Mean
Time Between Failures (MTBF) to 8000 hours, and increases service
life by 50% compared to traditional sleeve labeling machines.
Third, the equipment incorporates an innovative dynamic load
balancing structure that automatically adjusts operating tension
based on shrink film thickness (compatible range: 5-50μm). This
prevents film stretching and breakage even at maximum sleeve
labeling speeds of 600 bottles per hour, ensuring stable 24-hour
continuous production line operation.
II. Multi-Tiered Safety Protection, Embracing Human-Machine Harmony
The SPC-550 implements a comprehensive “Prevention - Monitoring -
Interception - Alarm” safety system, ensuring operator and
equipment security: First, infrared safety barriers encircle the
equipment, creating a 360° dead-angle-free safety zone. Should an
operator's limb or foreign object enter the operational area, the
system triggers an emergency shutdown within 0.05 seconds,
simultaneously cutting power and locking critical moving parts to
prevent mechanical injury. Second, to prevent improper human
operation (e.g., starting the equipment before mold fixation is
complete, forcing operation when membrane material is below the
safety threshold, or operating with safety doors open), the
equipment incorporates 12 intelligent sensors and a logic judgment
module. These continuously collect real-time operational data. Upon
detecting abnormal operation, the system immediately halts the
startup sequence and displays the fault cause on the Chinese
touchscreen control panel (e.g., “Mold not locked,” " Insufficient
Film Material") along with step-by-step troubleshooting guidance.
Simultaneously, it triggers audible and visual alarms (alarm sound
level ≥85dB, red flashing warning light) to mitigate safety risks
caused by human error. Furthermore, the equipment's overall safety
design complies with GB 5226.1-2019 “Electrical Safety of Machinery
- Part 1: General Requirements” and EU CE safety certification
standards. Critical safety components (e.g., emergency stop
buttons, safety door locks) have undergone third-party testing to
ensure compliance.
III. Modular Rapid Mold Change for Multi-Product Production
Flexibility
To address the complex and time-consuming mold change processes of
traditional sleeve labeling machines, the SPC-550 employs a
“modular integration + tool-free manual replacement” design,
significantly enhancing production line flexibility: Core
components directly contacting packaging materials—including
die-cutting assemblies, film feed channels, and bottle positioning
fixtures—are consolidated into independent standardized modules.
Each module features precise positioning reference surfaces and
quick-locking mechanisms. Operators can change packaging materials
without specialized tools, completing the mold change in just three
steps: ① Rotate the positioning pin to unlock and remove the old
module; ② Align and insert the new module onto the machine's
reference scale; ③ Secure it by tightening the manual knobs on both
sides. The entire process takes no more than 5 minutes, reducing
changeover time by 83% compared to the 30 minutes required for
traditional equipment. This significantly minimizes production line
downtime during product switching. This design accommodates
multiple shrink film specifications (width 20-150mm, roll diameter
100-300mm) and various bottle shapes (round, square, irregular
bottles with diameters 10-80mm and heights 50-300mm). It
accommodates small-batch, multi-batch production demands without
requiring modifications to the main equipment structure. This makes
it particularly suitable for scenarios involving frequent product
rotation, such as sample sizes for skincare products in the daily
chemical industry or seasonal limited editions in the beverage
industry.
