Equipment Overview:
This system comprises a heat shrink machine and a sealing/cutting
machine. It features "L"-type manual sealing/cutting, followed by
automatic transfer into the shrinking chamber to complete the process.
Core Components & Features:
Sealing System:
Uses an anti-stick, high-temperature resistant alloy "L"-shaped sealing
blade. The Teflon-coated blade ensures neat, crack-free, non-charring,
smoke-free seals and prevents film sticking.
Adjustability:
Manual handwheel for easy conveyor height adjustment; sliding film
holder accommodates various shrink film sizes; perforation device
operates smoothly.
Control & Safety:
Time relay for precise sealing/cutting control.
SF-20LG/B unit: Cylinder-driven sealing/cutting reduces workload and increases efficiency.
Sealing blade with automatic anti-miscut and overheat protection.
Emergency stop function.
Quality Components: Imported electrical parts for stable performance; imported high-temperature insulation curtains minimize heat loss.
Heating System (SF-4525):
Stainless steel heating tubes with auto-cooling extend machine life
over 3 times. High-power circulation motor ensures even heat
distribution.
Conveyance: Solid 45# steel roller shafts with silicone sleeves handle heavy loads without damaging film.
Flexible Operation:
Adjustable conveyor speed and chamber temperature based on product
size/volume. Compatible with fully/semi-automatic sealing machines for
easier operation.
Performance & Applications:
Versatility: Suitable for PVC, POF, PP, OPS, and PET films.
Efficiency: One-person operation, fast packaging speed, ideal for high-volume production.
Applications: Widely used in biscuits, printed materials, pharmaceuticals, flooring, ceramics, boxes, and other packaging fields.
Output Quality: Produces well-sealed, dust-proof, moisture-resistant packages with stable performance.
