Fried Instant Noodle Food Packaging Machine Works
1. Introduction Instant noodles, bread above the world’s second largest after the processed foods, instant noodles in China is the world’s first production and sales power. According to statistics, close to existing domestic noodle production line around 3000, the annual production capacity of 19 billion package, sales of 22.2 billion yuan in output and sales to remain significantly higher than the growth of more than 30%, far higher than the national food 20.6% of the average industrial growth rate. Data indicate that the adjustment as people diet and eating habits, and China’s sustained economic development, food packaging machinery industry to bring a good opportunity to promote a rapid development of food processing industry requires a large number of high-quality food packaging machinery, food machinery ultimate effect is to raise productivity and product diversification.
2. Fried instant noodle production process
Fried instant noodle production process: Material mixing, curing mix composite pressed continuously pressed slitting corrugated, forming the beginning of the cold Cooking Paste folding cutting off the taste sub-row cooling finished frying dehydration test finished sub-bag packing.
In this paper, the last one instant noodle production line processes: Sub-bag automatic pillow packing machine works.
3. Food Packaging Machine Works 1) Food Packaging Machine Overview: High technology applications of the results, use mechanical and electrical integration, simple operation, the control programmed by perfection. Automatic pillow packing machine is widely used, adaptable, can be used for biscuits, instant noodles, candy, ice cream and other small food packaging, can also be used in medicine, spare parts, textile, light industry and chemicals, and commodity packaging. The total width of the packaging materials up to 450mm, package size in length (95-350) mm, width (10-140) mm, high (5-70) mm range of free choice. Packaging capacity of 30-200 bags / min, using power: 4KW. Machine size: 5050 × 960 × 1800mm.
2) electrical system components: Power with three-phase five-wire system (or three-phase four-wire system) 380V/50Hz power supply, power consumption of about 5KW.
Host electrical system consists of three components, programmable controllers (PLC) and the speed sensorless vector control frequency inverter as the core part and the heating control section.
3) Automatic pillow works A) heating system System connected to control cabinet power supply, you can choose to heat. 48-volt heater safe voltage, set the desired heating temperature, generally takes about 20 minutes to reach the set temperature.
B) run and the speed setting
Programmable controller according to mode of operation, selectable manual and automatic operation, this time on the PLC device “POWER” and “RUN” indicator lights. Film and packaging material (noodle dough) After adjustment, the operating mode switch SA2 placed in “automatic” position, the track switch SA3 placed in “automatic” position, press the start button SB2, vertical closed solenoid YA1 pull, run power ring alarms about 2 seconds, the machine for continuous operation.
Host with KV2000 sensorless vector frequency inverter speed control. Inverter keyboard installed in the operating control cabinet, speed of implementation set by the panel potentiometer R1 speed. Inverter keyboard is displayed on the motor. Speed Rpm = (120 × F057 output frequency / F052 motor pole number) × gear ratio. Factory, the relevant parameters have been configured, users generally do not modify the parameters.
C) automatic packing machine pillow pack differentials and bag length adjustment machine (abbreviated)
D) tracking system Tracking control system is the core of packaging machine, the PLC program control (see some of the major PLC tracking program), the system can be packed to its shape and size of the accurate positioning, with positive and negative two-way track to further improve the tracking accuracy. Packaging materials in the production process to detect the error occurred, while compensation for accurate and correct, avoiding waste of packaging materials. The machine running, the film marked the detection sensor constantly film mark (color), while micro-mechanical part of the trace detection of mechanical position switches, the two signal sent to the PLC, by the process operation, by the PLC’s output Y6 ( is to recover), Y12 (anti-tracking) control and tracking to track positive and negative motor. If detected after the tracking number can not be scheduled to meet technical requirements, can automatically shut down for inspection, to avoid waste generation;
E) food packaging machine on Frequency Control requirements
Food packaging machine applications used in transmission although relatively simple, but the dynamic performance of the high transmission requirements, system requirements follow the fast dynamic performance and precision high-speed stability. Therefore, the inverter must be considered dynamic technical indicators, use high-frequency converter to meet the requirements.
F) KV2000 speed sensorless vector inverter features:
1) Application of speed sensorless vector control technology, with automatic tuning function automatically correct frequency in order to achieve stability of the load change in the effect of motor speed;
2) with high stability and fast dynamic response speed precision can meet the high performance occasions and transmission control requirements. Reduce the time due to transmission failures and economic losses. Also eliminates the need for speed sensor, with low maintenance costs.
3) has a feature rich, stable performance, small size, low noise operation and so on.
G) external line converter in the KV2000, mainly composed of six parts:
1) DC braking resistor terminals P +, DB external braking resistor R0; to stop when the system to achieve instant secure parking;
2) Control circuit input terminal in, FWD / REV is positive / reverse signal, which FWD received the Y0 output signal from the PLC, set the frequency converter is transferred by operation; X1, X2, X3, X4, X5, X6 to select a custom multi-input terminal, which receives X1 Y1 output from the PLC program control point signal by frequency converter to realize to move the operation;
3) the frequency given by the installation in control cabinet on the potentiometer R1 to set up, easy on-site operator according to the need for speed of production;
4) in the control loop output, TA and TC for the inverter output terminal failure, when the inverter fails, PLC input signal COM, X10 closed, process control system alarm and automatic parking;
4. Conclusion Pillow food packaging machine speed sensorless vector frequency converter, has the following advantages:
1) simplify the transmission system, improve the stability of the machine running
