Talking about the Transformation of Old Packaging Lines

In 1993, the company purchased a packaging line of 20,000 bottles per hour from the first light industrial machinery factory in Guangdong Province. By 1999, the equipment performance index was severely reduced, the production capacity could only reach 12,000 bottles per hour, and the overall packaging pass rate At only about 85%, the labor intensity of workers has increased significantly, which restricts the development of the company's output and quality. For this reason, we have carried out technological transformation of the line and achieved quite satisfactory results. Under the same conditions, the performance of the equipment exceeded. New line installed at the end of 1998. The technical reform project is introduced as follows for reference by peers.

1 Modification of RMZ-B30/356 Bottle Washer

1.1 Change the Temperature Control Valve of the Base I Zone from Electric Valve to Pneumatic Diaphragm Valve

Due to the large temperature fluctuations when using the electric valve, the control precision of the bottle washing process is affected. When the temperature is too high, the broken bottle rate will increase; when the temperature is low, the recycling bottle is not easy to clean, and before the transformation, the bottle washing machine is a “bottleneck” that restricts the output of the entire packaging line.

After changing to pneumatic film, the temperature control accuracy is within ±1°C. Under the condition of this equipment, the company's technical department promptly increased the temperature of the alkali I zone from 70 to 80°C to 80 to 88°C, greatly increasing the heat of the detergent. effect. At the same time, in order to solve the problem of increasing temperature difference, a warm water spray was added to the chain of the bottle washing machine. This transformation has enabled the recycling rate of recycled bottles to exceed 98%.

1.2 bottle washing machine speed change from mechanical speed to frequency converter speed

After changing the original wide-angle V-belt mechanical speed control to the inverter speed control, the equipment start-up noise was significantly reduced, and the balance was significantly improved. At the same time, the failure rate is reduced, which increases the effective running time of the equipment and increases the output of the class.

1.3 Add pipeline pump in the last spray

After the pipeline pump is added, the pressure of the spray pipe is increased from 0.05 MPa to 0.2-0.3 MPa to ensure that the paper fiber stuck in the bottle is flushed.

1.4 The spray device added to the warm water outside the clean area of ​​the bottle washer improves the bottle washing quality of the recycled bottle. The main results are as follows: (1) The water recycling rate is improved and the production cost is reduced; (2) The negative effect of the dust on the surface of the recycled bottles on the detergent is reduced; (3) The pre-soaking and preheating of the recycled bottles are performed. , Reduced the broken bottle rate and increased the rate of removal of the mark.

Through the above transformation, the bottle washing machine's production capacity reached 1.8 to 21,000 bottles/hour, and the bottle washing rate (recovery bottle) reached more than 99%.

2 Modification of VVF60/12 Bottle Capping Machine

2.1 Change the fixing method of wine jar

The original wine tank fixing device is worn badly, and it is difficult to purchase accessories, so that the wine loading level line floats relatively large, which affects the stability of the wine filling. Taking into account the characteristics of the bottles that are loaded are 640 mL bottles, the four cylinders are used to lift the ring cylinder lifting device. Replace the column and secure the flask to the flange. Although this method lags behind, it has greatly improved the uniformity of the horizontal line and the stability of the CO2 content, and at the same time reduced the wine damage.

2.2 Adding a secondary vacuum pumping device

After adding the second vacuum device, the original bottleneck air content was reduced from 6 to 7 mL to 1 to 2 mL.

3 Renovation of PIIS/2S-150 Sterilizer

Increasing the walking distance from 9cm to 12cm shortens the walking time from 22 seconds 44 to 20 seconds 44. This increases the production capacity of the sterilizer by 2 tons per hour to 13 tons and keeps the beer sterilization PU at 18 Between ~25, reduces the aging of the wine.
Modification of 4 Pairs of J23—15—4—16 Labeler

4.1 from a single section to take plastic to take two-stage glue, after taking the double section to take the glue to overcome the neck mark, body mark on the paper of the requirements of inconsistencies, reduce the incidence of defects, improve the operating efficiency of the machine .

4.2 The aluminum alloy target was changed to the plastic target, and the rubber roller was changed to the stainless steel roller, effectively avoiding the occurrence of misalignment between the drum and the holder table due to the stuck rubber roller of the scraper (steel material). .

4.3 The bottle transmission chain with the main drive wheel from the middle position to the front-end position, an increase of a common frequency converter to control the chain and the host speed, to solve the chain drive is unstable and easy to be broken fault.

Through the above transformation, the qualified rate of the labeling is more than 99.5%, and the balanced production is ensured, so that the problem that the semi-finished product stays in the sterilizer for a long time due to the failure of the labeling machine and the taste deteriorates is prevented. In the high season of 2000, the overall qualified rate of the transformed packaging line was over 99.2%, and the wine damage, bottle loss, mark loss, power consumption, water consumption, product quality, and output were all comparable to those of the new line. The production efficiency of the packaging line has increased by 60%, the quality of packaging has increased by nearly 20%, and the highest record of 4,500 tons of double-class production per month has been recorded, ensuring the successful completion of the company's annual production tasks.
