With the development of high-speed, high-efficiency, mechanization, and automation of the bottle blowing machine, its feeding method has gradually changed from manual to automatic. Several common forms are introduced below.

①Spring automatic feeding bottle blowing machine, spring automatic feeding bottle blowing machine usually consists of a motor, a spring chuck, a feed port, a spring and a plastic hard tube. When working, the motor drives the spring to rotate at a high speed to generate axial force and centrifugal force. Under these forces, the material rises along the plastic rigid tube. When it reaches the feed port, it is thrown to the discharge port and enters the hopper due to the centrifugal force. Its conveying capacity depends on the spring speed, spring outer diameter, pitch, and the gap between the spring outer diameter and the inner wall of the plastic hard tube. The diameter of the spring steel wire cannot be less than 6mm, otherwise it is easy to break. The bottle blowing machine is mainly used to convey powdery materials, commonly known as powder feeder, and is generally used to feed a single piece of equipment in the workshop.



②The blow molding machine with blast feeding mainly uses wind to blow the material into the conveying pipeline, and then into the hopper through the cyclone separator. The conveying capacity of this feeding system is related to the length of the pipeline. The bottle blowing machine is mainly used to convey granular materials, and is usually used in the centralized feeding system of large factories.

③Vacuum feeding bottle blowing machine. When the vacuum feeding bottle blowing machine is working, the vacuum pump creates a vacuum in the small hopper, and the material first enters the small hopper through the feeding pipe. When the material in the small hopper is stored to a certain amount, the vacuum pump stop working. Feeding is stopped due to the disappearance of the vacuum in the small hopper. At this time, the sealing cone is opened and the material falls into the large hopper. When the material is finished, the sealing cone is lifted up due to the action of the heavy hammer, and the small hopper is closed again. Touch the micro switch to make the vacuum pump start to work again, so reciprocating cycle. The bottle blowing machine is mainly used to convey granular materials, and is usually used to feed a single piece of equipment in the workshop. The filling function can ensure even feeding. The feeding screw is driven by the screw through the transmission chain. The screw rotation can strengthen the material conveying in the screw feeding section, and it is equipped with an overload protection blow molding machine. When the feeding port is blocked, the pressure exceeds the force of the spring, and the spiral will rise, or there are longitudinal grooves on the feeding spiral. When the pressure exceeds, the material will flow back through these longitudinal grooves to prevent the feeding hopper from being damaged. The bottle blowing machine is mainly used to convey powdery materials, and is usually used to feed a single piece of equipment in the workshop.

In addition to spiral forced feeding, there is also an electromagnetic vibrating hopper for feeding. The electromagnetic vibrating bottle blowing machine is installed on the hopper, and the phenomenon of "pipe hole" and "bridging" is eliminated through intermittent vibration.

The above is the relevant content of the bottle blowing machine, I hope it will be helpful to everyone.
