Product Specification: Capping Machine (SGJ-80)

SGJ-80 Capping Machine

This specification details the SGJ-80 semi-automatic electric and pneumatic capping machine. Engineered for cosmetics, daily chemical, pharmaceutical, and food industries, it excels at sealing complex and irregular caps including spray, pump, and trigger caps. Built with 304 stainless steel and dual motors, it delivers speeds up to 45 caps/min, leveraging constant pneumatic downward pressure and digital torque control to ensure high-efficiency, non-damaging capping.

1. Product Overview

  • Product Category: Semi-Automatic Electric & Pneumatic Capping Machine
  • Application Scenarios: Widely used in cosmetics, daily chemicals, pharmaceuticals, and food industries. Ideal for production line sealing of complex caps (such as spray nozzles, pump heads, duckbill caps, trigger sprayers, etc.).
  • Core Function: Combines electric rotational drive with pneumatic downward pressure control to achieve high-speed, high-precision capping across various cap materials and shapes.
  • ** Operation Requirement: This is a pneumatic model and MUST be connected to an air compressor (air pump) to operate.**

2. Key Advantages

  1. Industrial-Grade Materials: Main electric control box and brackets are constructed from 304 stainless steel, while the baseboard and chassis feature anodized aluminum alloy treatment for durability and corrosion resistance.
  2. Imported Dual-Motor Drive: Equipped with high-power imported brand motors, delivering ample power reserves, smoother capping, and an extended service life.
  3. High Efficiency: Significantly faster than traditional models, the SGJ-80 achieves capping speeds of up to 45 times/minute.
  4. Digital Precision Control: Utilizes a digital relay control system to independently adjust capping time, locking time, torque level, and rotation speed, effectively preventing cap damage.
  5. Master of Irregular Caps: Pneumatic downward motion combined with adjustable torque effortlessly handles challenging sealing tasks like duckbill caps, pointed nozzle caps, and non-standard plastic caps.

4. Sales Recommendations & FAQ

Sales Recommendations

  • Core Selling Points: Focus on "High Compatibility" and "High Efficiency". Emphasize stability when handling irregular caps like pump heads/spray nozzles, which pure electric capping machines struggle to achieve.
  • Customer Reminder: Always verify whether the customer has an air compressor on site prior to closing the sale. Recommend a silent, oil-free small air pump with ~0.5 MPa operating pressure.
  • After-Sales Advantage: 1-year full warranty with lifetime technical guidance. All wearable parts are standard components (e.g., AirTAC pneumatic cylinders), keeping maintenance costs minimal.

Frequently Asked Questions (FAQ)

  • Q: Why is this machine better than a pure electric model?
    • A: Pneumatic downward force provides constant, uniform pressure, preventing thread stripping or loose seals caused by inconsistent manual pressure. Additionally, pneumatic operation better protects the motor, extending machine lifespan.
  • Q: Is it complicated to adjust for different bottle heights?
    • A: Very simple. Just loosen the side fixing screw and turn the top handwheel to adjust the capping head height—no tools required.
  • Q: Can cap tightness be adjusted?
    • A: Yes. You can precisely control tightness by adjusting torque settings on the digital panel and regulating air inlet pressure.

6. Operating Workflow

  1. Air & Power Connection: Connect to power supply, insert air compressor pipe into the quick-connect inlet, and adjust pressure to standard operating range.
  2. Height Adjustment: Place a target bottle and adjust capping head height until it sits approx. 5–10 mm above the cap.
  3. Parameter Setting: Set capping time and interval time on the digital display according to cap material (or switch to foot-pedal mode).
  4. Bottle Placement: Operator places bottle (with pre-positioned cap) into the positioning slot and triggers foot switch or sensor.
  5. Automatic Capping: Pneumatic cylinder drives the capping head downward rapidly to rotate. It automatically stops and resets once target torque or duration is reached.
  6. Product Removal: Remove the sealed bottle and proceed to the next cycle.
