There are many key points to pay attention to when installing the film blowing machine. First, The center line of the extruder head must be accurately aligned with the center of the traction roller, and there must be no deviation in the vertical and horizontal planes. When operating the automatic fresh-keeping bag making machine, ensure that the traction speed and the winding speed are properly balanced, and make necessary adjustments in time as the winding diameter increases. After the main machine is started, its operating status must be closely monitored, and the electrical instruments and controllers must be adjusted at any time to ensure smooth operation.
The main machine gearbox and traction reduction box need to be refueled and the gear oil replaced regularly to ensure smooth operation of all rotating parts. For new machines, The gear oil must be replaced within ten days of use. During the refueling process, be careful to avoid overheating or jamming of parts. At the same time, tighten all connection points to prevent the bolts from loosening. Always keep an appropriate amount of compressed air in the bubble tube, because the bubble tube is prone to leaking during the pulling process, so be sure to add air at any time to maintain its normal function.
The application range of the film blowing machine varies depending on the material used. For example, the film produced by the PP film blowing machine is suitable for supermarket shopping bags, bacterial bags and other scenarios. This film is characterized by high hardness, and the requirements for stretch and brightness are not very high. High-pressure PE film blowing is suitable for the production of various fresh-keeping bags, and the recycled film can be used to make garbage bags, etc. In short, the film blowing machine plays a vital role in various industries with its versatility.
The film bubble automatic temperature control device of the Blown Film Machine is equipped with a film blowing head, which is provided with an air intake pipe and an exhaust pipe. The exhaust fan drive circuit and the air intake fan drive circuit are respectively connected to the corresponding fans. A temperature sensor is arranged inside the exhaust pipe to accurately measure the temperature of the air.
In addition, a central control processor is provided, which includes a temperature reference value setting circuit and a temperature value comparator. The temperature sensor is connected to the temperature value comparator, and the temperature value comparator continuously compares the actual temperature value with the temperature reference value to achieve accurate adjustment of the temperature.
