Description

Technical Field

[0001] The utility model relates to the technical field of bottle blowing machines, and more particularly to an exhaust device for bottle blowing machines. Background Art

[0002] A bottle blowing machine is a machine that blows plastic pellets or preforms into bottles through a certain process. It is mainly used to produce hollow containers, such as plastic bottles, and is widely used in the beverage, pharmaceutical, cosmetic, food, and chemical industries.

[0003] A search revealed an exhaust device for a blow molding machine with the existing publication number CN209649441U, which includes an air source, an exhaust nozzle, an exhaust valve, and a control unit. The exhaust nozzle is connected to the air source via a pipeline, and the control unit controls the exhaust valve via an intermediate relay, enabling or stopping exhaust from the nozzle. The intermediate relay is a solid-state relay. This exhaust device reduces the blow molding machine's failure rate by replacing the electromagnetic relay that controls the exhaust check valve with a solid-state relay.

[0004] The blow molding machine oven is designed as an open design, and the exhaust device is installed in the middle of the oven. Due to the problem of heat rising in the production process, heat is easily accumulated on the top, and the air conditioner directly delivers cold air downward to the oven. The temperature fluctuates greatly during production, resulting in unstable empty bottle process and excessive defects. Therefore, we proposed an exhaust device for blow molding machines to solve the above problems. Utility Model Content

The exhaust joint is connected to an external pipeline. When the bottle blowing machine is working, the exhaust fan is started by an external control device. The heat generated during the operation of the bottle blowing machine is discharged directionally along the external pipeline under the action of the negative pressure at the opening position of the exhaust hood, thereby reducing heat accumulation and balancing the heat energy above the drying oven. After the transformation, the empty bottle process is significantly stabilized, the defective rate has been reduced to within the standard range, and the production quality is improved.
