The operation process of the blow molding machine is to preheat and heat up first, set the temperature value on the temperature control instrument according to the process requirements, start the heating system to heat up, and check whether the current indication value of each section of the heater is normal. After reaching the processing temperature, Start feed production. Whether it is driving the tractor, or after the cutting machine is powered on, there will be a certain noise.

The clamping conveying device of the tractor runs slowly, the heating device is heated according to the process requirements, and the heating temperature is adjusted according to the program. After the temperature reaches the technological requirements, the prefabricated tube blank is sent to the heating device with a special clamping mechanism. After the tube blank is heated to the desired temperature, the mandrel is placed from one end. The mandrel is provided with air inlet holes and can move axially. Welded tube bottom. The upper module of the heating device is pressed down, so that the bottom of the tube blank is welded to form the bottom of the bottle. The mandrel sticks out upwards, stretches the entire tube blank axially, and injects compressed air at the same time to radially inflate the tube blank, thereby realizing bidirectional stretching orientation.


Then, a cooling medium is introduced into the blow mold, so that the biaxially stretched product is rapidly transported, cooled and shaped to obtain a plastic hollow product of the desired shape. In this series of production processes, some noises are often inevitably generated, affecting the life and rest of the surrounding people. This requires us to formulate safe operating procedures for extrusion blow molding machines to avoid or reduce noise as much as possible.

At present, light bricks or hollow bricks are used in general workshops as the outer walls. These materials have poor sealing performance. During production, the noise emitted by the machine when it vibrates randomly will hinder people from resting, studying and working normally. If it is in a residential area, it will have a great impact. You can also make a light steel layer on the wall next to the road, add a paper-faced gypsum board with an interlayer filled with sound insulation cotton, and then use ordinary wall paint to treat the surface.

There are three solutions to reduce noise during product blow molding operations

1. First, reduce the noise from the sound source, that is, the windows of the workshop should be tightly sealed. Whether you are a single-layer window or a double-layer window, the sealing is the main thing. It is also a simpler way to consume part of the sound energy by using thick curtains, but of course it is not a very effective way

2. Another is to reduce the noise during the sound transmission process. Double-layer curtains can be installed on the windows of the workshop, and thicker and thicker floor-to-ceiling curtains are used. When starting production, close the windows and draw the double-layer thick curtains, which can effectively reduce noise and absorb part of the noise.

3. Attenuate noise at the human ear. Workers who are operating can wear earplugs to reduce the impact of noise on themselves.

The above content is the method to solve the noise of the blow molding machine, I hope it will be useful to you.
