What are the precautions when operating the powder filling packaging line

Equipment safety is the basis for ensuring production continuity. Before operating the packaging line, the equipment must be fully inspected, focusing on the integrity of the power supply line, the lubrication condition of the transmission parts, and the accuracy of the sensors and weighing devices. For example, a food company failed to detect the deviation of the sensor in time, resulting in excessive packaging weight, which in turn triggered a large-scale return event. In addition, the equipment should be equipped with safety devices such as emergency stop buttons and protective covers, and regular effectiveness tests should be conducted. During operation, it is strictly forbidden to put your hands into the area of ​​​​the moving parts, and it is forbidden to adjust parameters or perform maintenance operations while the equipment is running. For example, a pharmaceutical company violated the regulations and caused the operator's fingers to be involved in the sealing machine, resulting in a serious industrial accident.

Accurate control of process parameters is the key to improving packaging quality. Parameters such as packaging speed and filling pressure should be dynamically adjusted according to the characteristics of the material. For example, ultrafine powders are prone to dust and "bag explosion" due to their small particle size and high air content. Therefore, heat sealing technology is required to ensure that the sealing edge is flat and burr-free; for sticky powders, special edge sealing materials are required. A chemical company failed to optimize parameters for material characteristics, resulting in a packaging bag breakage rate of up to 15%, causing huge economic losses. In addition, it is necessary to regularly check the cutting effect of the packaging film to ensure that the seal is tight and there is no powder leakage, and strictly control the amount of material put in to avoid overload operation of the equipment.

Personnel protection is an important part of reducing occupational health risks. Operators must wear personal protective equipment such as dust masks, protective glasses and gloves throughout the process. Due to inadequate protective measures, a flour mill caused many employees to suffer from pneumoconiosis, and the company was forced to suspend production for rectification. At the same time, professional training should be provided to operators to familiarize them with the structure, performance and emergency handling procedures of the equipment. For example, a company introduced a virtual simulation training system to reduce the operating error rate of new employees before taking up their posts by 60%. During the operation, it is very important to stay focused, and it is strictly forbidden to place irrelevant items in the operation area to prevent interference with the normal operation of the equipment.

Environmental management is the core link to ensure production stability. The operation area should be well ventilated, and residual powder inside and outside the equipment should be cleaned regularly to prevent dust accumulation from causing equipment failure. A coating factory neglected equipment cleaning, causing the transmission parts of the packaging machine to get stuck, and the repair cost was as high as 200,000 yuan. In addition, the reliability of the grounding system needs to be checked regularly to prevent static sparks from causing explosions. For the packaging of ultra-fine powders, explosion-proof electrical equipment must be used and gas concentration monitoring devices must be installed. For example, a new energy company has introduced an intelligent environmental monitoring system to control dust concentration below the safety threshold, effectively avoiding the occurrence of safety accidents.
