100 Interview Questions and Answers: Blower Feeder Dyed Raw Stock

  1. What is a blower feeder?

    • Answer: A blower feeder is a machine that uses air pressure to transport dyed raw stock (typically fibers or strands) from a hopper or storage bin to a processing unit, like a carding machine or spinning machine.

  2. Describe the process of dyeing raw stock.

    • Answer: Dyeing raw stock involves immersing the fibers in a dye bath under controlled temperature and time to achieve a desired color. The process often includes pre-treatment (cleaning), dyeing, and post-treatment (rinsing and drying).

  3. What are the different types of blower feeders used in the textile industry?

    • Answer: There are various types, categorized by factors like air pressure system, material handling capabilities, and control systems. Examples include positive pressure blowers, negative pressure blowers, and those with different types of conveying lines and material handling mechanisms.

  4. How does a blower feeder prevent fiber breakage?

    • Answer: Careful design and operation minimize fiber damage. This includes using appropriate air pressure, optimizing the conveying line's design to reduce sharp bends and friction, and selecting materials that are gentle on the fibers.

  5. What are the advantages of using a blower feeder?

    • Answer: Advantages include increased efficiency (continuous feeding), reduced labor costs (automation), consistent material flow, and improved hygiene (reduced manual handling).

  6. What are the disadvantages of using a blower feeder?

    • Answer: Disadvantages can include higher initial investment cost, potential for fiber damage if not properly maintained or operated, higher energy consumption, and complexity in maintenance.

  7. How is the air pressure in a blower feeder regulated?

    • Answer: Air pressure is regulated using valves, pressure sensors, and control systems. The system often incorporates feedback mechanisms to maintain a consistent airflow and prevent over-pressurization.

  8. What are the common maintenance tasks for a blower feeder?

    • Answer: Regular maintenance includes checking air pressure, inspecting conveying lines for blockages or wear, cleaning filters, lubricating moving parts, and inspecting the blower motor and other components.

  9. How do you troubleshoot a blower feeder that is not feeding properly?

    • Answer: Troubleshooting involves checking for blockages in the conveying line, verifying air pressure, inspecting the blower for proper function, checking the hopper for sufficient material, and examining the control system for malfunctions.

  10. What safety precautions should be taken when operating a blower feeder?

    • Answer: Safety precautions include using proper personal protective equipment (PPE), ensuring proper lockout/tagout procedures during maintenance, guarding moving parts, and following all manufacturer's instructions.
