Explosion Proof Automatic Capping Machine For Insect Repellent Bottles

Explosion-protected Automatic Capping Machine

Key Features

• Precision Tube Insertion: An innovative guide fork mechanism forces even severely bent dip tubes straight, ensuring 100% accurate insertion into the bottle neck.

• Absolute Torque Control: Independent servo motors drive the 3-jaw capping heads, guaranteeing a release torque of ≥1.5 Nm to completely eradicate leakage risks.

• Continuous Tracking Motion: 3 tracking placement heads and 1 tightening head cap bottles during uniform movement, eliminating liquid splashing caused by abrupt stops.

• Damage-Free Handling: Capping claws feature flexible polyurethane contact points, flawlessly protecting premium electroplated pumps and bottles from scratches.

• Smart Defect Rejection: Integrated photoelectric sensors and pneumatic fingers detect missing or crooked caps, triggering alarms and pausing infeed for that specific station.

• Flexible Changeover: Accommodates diverse bottles from 130-400mm in height; all changeover parameters are instantly retrievable via the HMI touchscreen and handheld controller.

The Automation Challenge & Our Solution

In the North American daily chemical (hand sanitizers, shampoos, lotions) and pharmaceutical syrup markets, "Dispenser Pumps" with long dip tubes are notoriously the ultimate nightmare for automation. Dip tubes easily bend during bulk transit, causing conventional cappers to miss the bottle neck, subsequently crushing the pump or tipping the bottle. Furthermore, inadequate torque application leads to catastrophic leaks in e-commerce fulfillment networks (like Amazon), resulting in massive chargebacks. This equipment features a revolutionary ground-up redesign to systematically eradicate these exact pain points.

Revolutionary Dip Tube Guidance & Insertion System To conquer the core issue of bent dip tubes, the machine is equipped with an exclusively developed "Tube Insertion Guide Fork" system. When the capping head grips the dispenser pump, the fork mechanism instantly engages, securing the base of the pump. As the capping claw descends, the fork remains relatively stationary, physically forcing the bent tube straight and guiding it accurately into the bottle opening. This ingenious mechanical synergy solves a world-class automation challenge, guaranteeing an exceptional insertion yield.

Servo-Driven Absolute Torque Control for Leak Prevention The sealing integrity of premium personal care products defines a brand's reputation. Bypassing traditional pneumatic friction cappers, this machine utilizes high-end "Inovance Servo Motors" to provide independent power to each 3-jaw capping head. Through fully digitized torque regulation, the system ensures the tightening force on every single pump is absolutely uniform (with a release torque of ≥1.5 Nm). This absolute mastery over torque physically eliminates any possibility of cross-threading or loose caps that lead to fluid leakage.

Continuous Tracking Motion & Flexible Product Protection To achieve a high-efficiency output of ≥50 BPM while preventing liquid spills, the equipment employs a Linear Tracking design. Bottle clamping and capping motions are executed synchronously while the conveyor moves at a uniform speed. Eliminating the traditional "stop-and-go" phase means completely bidding farewell to liquid splashing. Simultaneously, all parts contacting the premium pumps are crafted from flexible polyurethane. Combined with a "one-station, one-bottle, one-pump" pairing logic, it ensures zero scratches, zero scuffs, and zero jamming even at maximum operating speeds.
