What Faults Often Occur in The Production Process Of ABA Film Blowing Machine?

ABA film blowing machine is the core equipment in the process of plastic film manufacturing. Its stability and production efficiency will directly affect the quality and output of the film. It is an automated equipment widely used in food, medicine, cosmetics and other industries. ABA film blowing machine plays a vital role in many industries such as packaging, agriculture and construction. However, in the manufacturing process, ABA film blowing machine will inevitably encounter various faults. How to timely and effectively eliminate these faults is one of the keys to improving production efficiency and ensuring product quality. This article will conduct an in-depth analysis of the problems often encountered by ABA film blowing machine in the manufacturing process, and explore how to diagnose and solve these problems.

What are the common faults of the extrusion system of ABA film blowing machine, and how to diagnose and solve them?

The core component of ABA film blowing machine is the extrusion system, whose main responsibility is to heat, melt and extrude the plastic raw materials. Due to its harsh working environment, the extruder is required to have high reliability and safety. However, in the real production process, the extrusion system often encounters various faults.

Frequent problems include: screw blockage, abnormal barrel temperature, and motor overload. Screw blockage generally occurs in the extruder, while abnormal barrel temperature occurs in the cooler and extruder. Screw blockage is often caused by foreign matter mixed into the raw materials or their quality is not up to standard. At this time, it is necessary to check the quality of the raw materials and ensure the cleanliness of the screw. Abnormal barrel temperature can cause material agglomeration and sticking. At this time, it is necessary to detect the barrel temperature and remove the blockage. Abnormal barrel temperature may be caused by damage to the heating component or failure of the temperature control system. In this case, it is necessary to measure the temperature of the barrel and replace the damaged heating component or repair the temperature control system. Motor overload may be caused by excessive load on the motor or failure of the motor itself. In this case, it is necessary to check the current of the motor and adjust or replace the motor accordingly.

In order to diagnose these faults, we can consider the following methods: First, check the quality of the raw materials to ensure that there are no foreign objects in the raw materials and the quality is stable; next, use a thermometer to measure the temperature in the barrel to ensure that it is maintained within the normal temperature range; finally, we use an ammeter to detect the current of the motor to ensure that it is not overloaded.

When the fault is diagnosed, we should implement appropriate response strategies: for the problem of screw blockage, it is necessary to clean the screw and check the quality of the raw materials; when the temperature of the barrel is abnormal, it is necessary to replace the heating component or repair the temperature control system; in the face of the motor overload problem, it is necessary to adjust the motor load or replace the motor.

What faults are prone to occur in the die head part in the production of ABA film blowing machine, and what impact does it have on the quality of the film?

The die head is not only the outlet of the extrusion system, but also a key link in the film generation process. In film production, when product defects are caused by unreasonable die head design or improper use, the entire production line is often shut down or suffers great losses, or even the entire production line is scrapped. Problems with the die head will directly affect the quality of the film.

Common die problems include: die blockage, inappropriate flow channel design, and uneven die temperature. Among them, die blockage is the most likely place for failure. If the die is blocked, it may cause breakpoints or uneven thickness of the film. At this time, it is necessary to check the cleanliness of the die and clean it. The fragility of the die flow channel is the main cause of die blockage, so it is necessary to detect the integrity and sealing of the flow channel. If the flow channel is not designed properly, it may cause uneven thickness or spots of the film. At this time, it is necessary to verify the flow channel design and optimize the flow channel structure. Uneven die temperature will cause film shrinkage and warping. At this time, the die temperature distribution must be detected. If the temperature distribution of the die is uneven, it may cause the transparency of the film to decrease or wrinkles to appear. Therefore, it is necessary to measure the temperature distribution of the die and adjust its temperature accordingly.

In order to diagnose these faults, we can consider the following ways: first, ensure the cleanliness of the die to prevent the die from clogging; next, we use the flow channel verification tool to check the suitability of the flow channel design; finally, we use the thermometer to measure the temperature distribution of the die to ensure the uniformity of the temperature distribution.

When the fault is diagnosed, we should implement appropriate response strategies: for the blockage of the die, it is necessary to clean the die; for the unreasonable flow channel design, it is necessary to optimize the flow channel structure; for the uneven temperature of the die, it is necessary to adjust the temperature of the die.
