According to relevant records, Buddhist incense was originally donated by various countries in the Western Regions. In early times, it was mainly used to eliminate stagnation and treat diseases. The record of offering incense to the Buddha dates back to the period of Emperor Wu of Han. Since then, the continuity of Buddhist incense has demonstrated the spirit of respecting ancestors and gods in Chinese society, and has become an essential part of traditional Chinese culture. Burning incense when praying and offering respects to Buddha has become an important custom, regardless of Taoism, Buddhism, or daily life. It is reported that in Mount Tai alone, the accumulated consumption from burning incense by worshippers reaches up to 80 million RMB per year, and the temple incense money during the Spring Festival in Taiwan and Hong Kong amounts to several hundred million RMB. With the further opening up of religious beliefs, the demand for various incense products is also increasing.
Due to the complexity of the traditional incense-making process, slow production speed, high dust content, and high cost, it has severely restricted the production and development of this product. The advent of CNC fully automatic incense making machines undoubtedly will thoroughly change the current situation of the incense industry with its numerous advantages.

The fully automatic CNC incense making machine consists of several parts, including material feeding, mechanical stick feeding, extrusion molding, and the PLC control system. Among them, the KE300A F-type incense making machine-specific frequency converter drives the motor to act on the cam connecting mechanism, which realizes the functions of material feeding and extrusion molding. The extrusion molding is achieved by the cam driving the connecting rod to move back and forth. The following figure shows the meaning:

Mechanical stick feeding is divided into stick feeding and stick moving. Stick feeding sends the bamboo stick to the extrusion track. When the stick feeding is completed, the infrared sensor detects that the bamboo stick is ready and outputs the stick feeding signal, which is sent to the PLC control system.
The frequency converter receives the stick feeding signal calculated by the PLC control system, and accelerates the running frequency from 0Hz to the given frequency within 0.1 second and completes the extrusion action at the given frequency. In this application, the given frequency is 75Hz.
When extrusion begins, the stick moving action (i.e., the bamboo sticks move laterally on the extrusion track) starts. After the stick moving is completed, the infrared sensor detects that the signal disappears, and the frequency converter begins to decelerate for 0.2 seconds. The complete extrusion molding process is then finished.
The control system is responsible for signal acquisition, computation, setting, and overall control of each link of the device.
If the incense making machine frequently reports overcurrent or overvoltage faults, while ensuring the output per unit time, the acceleration and deceleration time can be appropriately increased.
If the incense making machine frequently reports overcurrent or overvoltage faults, and the output per unit time does not meet the requirements after increasing the acceleration and deceleration time, try reducing the overcurrent loss gain coefficient and increasing the overcurrent loss protection current coefficient.
If neither of the above-mentioned methods works, try increasing the braking resistance.
The on-site pictures of the application are shown below:
The fully automatic incense making machine driven by the MICNO KE300A has the following advantages:
Automatic stick feeding and automatic cutting, no need to stop the machine for feeding, one-person operation, and one-time molding.
High efficiency: Now adopts mechanical stick feeding, which is efficient, simple, and durable. It can wear 190-210 bamboo sticks per minute, has less stuck bamboo, and can make 91,200-108,000 bamboo sticks per day by calculating 8 hours of incense making per day.
High-quality finished products: The incense stick is smooth, and the top and bottom parts are flat.
Energy-saving: Power-saving (the motor only runs when the bamboo stick is worn), and little waste (the less waste, the more it can avoid the waste of electricity, time, and manpower caused by repeated use of the waste).
Comfortable, environmentally friendly, and hygienic working environment, greatly reducing the labor intensity of workers. The machine operation is simple, easy to use, and ordinary workers can quickly master it.
Equipment performance: The equipment has a unique shape, a lightweight body, flexible transportation and use, no need for installation, and can be used after purchase. The technology is mature, and most accessories use imported materials, which are not easy to damage and are durable.
In the application site, the incense-making equipment equipped with the KE300A-2R2G-T4-F was adjusted to reduce the slowing down time to 0.1 second, which could run safely and stably, and the production capacity per unit time exceeded expectations. The incense-making equipment equipped with the KE300A-2R2G-T4-F was adjusted to reduce the deceleration time to 0.2 second, which could run safely and stably, and the production capacity per unit time met expectations. After a long period of testing and operation, the incense produced was smooth, and the top and bottom parts were flat. There were no stuck sticks or other faulty phenomena. The KE300A dedicated incense making machine frequency converter is deeply loved and recognized by customers for its excellent performance and test results.
