1. There are many reasons for the unstable discharge of the blow molding machine. It may be that the temperature when starting up is low and cannot meet the standard; the temperature of the extrusion cylinder or die is unstable; Adhesive sticking; back pressure too low; filter clogged. To solve this problem, check these components and make appropriate adjustments. Large-scale hollow blow molding machine 2. Uneven product wall thickness distribution Uneven product wall thickness distribution is a common problem. The cause of this failure is generally related to cooling and processing time. When the temperature and heating temperature are uneven, insufficient cooling will cause Affecting the wall thickness distribution of blow molding Zhiping, it is necessary to adjust the tube wall control technology of the hollow blow molding machine to alleviate the frequency of failures. The hollow plastic blow molding machine 3. The material cannot be fed. It may be that the battery is in a load state, which will affect the feeding of the equipment. If it is serious, it will affect the hollow blow molding machine unable to produce products normally. There are so many common failures of hollow blow molding machines, so in the process of daily use, the medicine should pay attention to the following 4 points: 1. In order to reduce the self-weight sagging of the parison, under the permitted conditions, accelerate the extrusion rate of the parison and reduce the waiting time of the mold 2. In the production process, the molding cycle should be shortened as much as possible on the premise of ensuring that the product is fully cooled; 3. The inflation pressure should be satisfied during the operation, and the air blowing rate should be fast; 4. Control the temperature and speed of the extruder, this is to Guarantee the quality of the parison and the quality of the products;
In an age when bottle blowing machine is increasingly important, the researchers believe manufacturers should pay close attention to their results.
