burning incense has a long history in our country and even in the world. in all parts of our country, both cities and villages burn incense. such as spring festival, qingming festival, first, fifteen, seven and a half moon, buddha, god, temple, funeral have incense habits, incense industry is a one-time consumer goods of the country and the world market never saturated, burning incense in china has a huge market, but due to the traditional incense production process is complicated, slow, dust and the high cost of operating in the production and consumption of each link restricts the production and development of the product. the manual production operators have look forward to the advent of incense machine. undoubtedly, the utility model "incense making machine" goes to the market with many advantages. at present, the types of incense making machines in the market are auxiliary type, labor-saving type, one-time molding and fully automatic type.
1. automatic incense machine components
the automatic numerical control incense making machine is composed of raw material feeding, mechanical feeding, extrusion molding and plc master control system.
feeding system: powder mixing mechanism and a blade driven by the inverter, can be powder mixing into uniform, moderate humidity block, and the scraper pushed out of incense mold.
send sign system: automatic and manual send signed send signed, manual send signed only one pair of friction wheel, will be sent to the bamboo fragrant powder attached mold, finished product, the efficiency is relatively low; automatic stick conveying mechanism driven by a motor, and a counter, adjustable speed, high production efficiency, and ac converter. linkage minutes processing of 250-300 bamboo incense.
2、control principle of automatic incense making machine
(1) mechanical delivery is divided into two stages: send, sign and ship. send signed is sent to a predetermined position track out of bamboo, when send signed, the infrared sensor is detected bamboo have been completed, the output signal sent to sign, and sent to the plc control system.
(2) the inverter receives the send signal after the operation of the plc control system to complete the signal. within 0.1 seconds, the operation frequency is accelerated from 0hz to a given frequency, and the extrusion action is completed at a given frequency. in this application, the given frequency is 75hz.
(3) when the extrusion, transport sign (complete translational movement in bamboo extrusion action began to track). when the sign is finished, the infrared sensor detects the signal disappears, the inverter starts to decelerate, the deceleration time is 0.2 seconds. at this point, a complete extrusion process is completed.
the fr150z type inverter for incense machine special inverter, compared with the standard fr100 model, part of the program has been used according to the characteristics of incense making machine to do the adaptation, and add some special incense machine functions (such as current, voltage suppression suppression, jitter suppression etc.), the user when in use, no need to do more complex settings, only need to do simple modifications to the actual parameter field use.
