Kenwei Troubleshooting Guide: Solve Common Multihead Weigher Issues and Optimize Weighing Performance

Kenwei has recently received feedback from customers encountering various issues while operating their combination weighers. To address these concerns, our after-sales team has compiled a list of frequently asked questions along with clear, professional solutions. We hope the following insights will help improve your weighing system performance and resolve common issues efficiently.

Q: When should I calibrate the touch screen?
A: Calibration is necessary after replacing the touch panel, display circuit board, or downloading a new program to the display.

Q: Can I install Arabic and Spanish on the device monitor?
A: Yes. Kenwei touch screen monitors can store up to four languages simultaneously. For example, you can configure 8 English interfaces, 10 Spanish, 12 German, and 14 French interfaces on one display.

Q: What are the advantages of dual motor-driven hoppers?
A: Single-motor systems may experience sealing issues with large-sized materials due to poor self-locking. Kenwei's dual motor drive allows independent control of each hopper door, enhancing sealing performance, flexibility, and stability. It supports multiple configurations—like "one-to-two" and "selection mode"—without needing to disassemble any connecting rods.

Q: Why does the touch screen briefly pause when pressing buttons during operation?
A: This delay prevents empty bags from forming in the packaging machine. If the system pauses immediately after sending a "ready" signal without responding to the packaging machine’s discharge request, an empty bag may result. The 3-second delay allows the signal to complete, eliminating this issue.

Q: What makes the Kenwei hopper system superior?
A: Kenwei's hopper system supports four functional modes with two-motor drive technology. It ensures full closure after each cycle, prevents material leakage, and allows quick mode switching via interface settings without disassembly. It simplifies operations, especially when switching between materials and packaging formats.

Q: How does the cutting function help prevent inlet blockage?
A: For materials like small buns, jelly, or nuts, simultaneous discharge can clog narrow inlets. Kenwei’s "orderly cutting" function staggers material discharge by adjusting "hopper count" and "door open time," enabling smooth material flow and eliminating blockages.

Q: How to ensure effective weighing and packaging of frozen foods?
A: Frozen foods (e.g., dumplings, shrimp, meatballs) often pose challenges such as clumping, moisture, and damage from extended exposure. Kenwei offers tailored solutions:

• Feeding Optimization: Use high-sensitivity sensors to maintain consistent material flow and prevent overload.

• Vibration Control: For ring-shaped items like shrimp rings, a rotary main vibrator ensures even distribution.

• Anti-Sticking Function: Kenwei’s unique “non-combination frequency” detection forces low-usage hoppers to discharge in subsequent cycles, avoiding material spoilage from prolonged storage.
