The blockage valve is arranged on the lower part of the valve body, the blockage valve is connected with the valve body in a bolting mode, the valve core is arranged in the valve body, the valve is provided with a ventilation port, a sealing gasket is arranged between the valve core and the ventilation port, the adjustment bag comprises an adjusting bag seat, a coupling shaft, an adjusting bag lower cover, an adjusting bag upper cover, a top cover, a spring, a membrane lower pressing plate, a membrane, a membrane upper compressing plate, an air inlet pipeline and an air outlet pipeline, the upper part of the valve body is connected with the adjusting bag seat in a bolting mode, the adjusting bag seat is internally provided with the coupling shaft, the coupling shaft is connected with the valvecore, and the upper part of the adjusting bag seat is connected with the adjusting bag lower cover in a bolting mode. The invention provides a vacuum adjusting device, according to the vacuum adjusting device, multiple rank machines share one set of vacuum, individual pressure adjusting is realized according to the different vacuum degree requirements of each rank machine, the investment of the device in the primary period can be reduced, and the operation cost can be reduced.

Description

technical field [0001] The invention relates to the field of glass bottle production, in particular to the field of glass bottle production machinery, and specifically refers to a vacuum regulating device. Background technique [0002] Vacuum-assisted forming is used in the production process of glass containers. The purpose of using vacuum-assisted forming in the forming mold is mainly to remove the air inside the forming mold, so that the glass can quickly and completely contact the inner wall of the forming mold. The vacuum is also used as a means of cooling to facilitate maximum internal heat transfer. Vacuum forming is an effective method to prevent bottle deformation and increase machine speed. [0003] At present, in the known vacuum-assisted forming process of the rank machine, it is necessary to adjust the appropriate vacuum degree according to different products. Usually, a rank machine is independently equipped with a vacuum pump and the vacuum pump is adjusted b...

Problems solved by technology

[0003] At present, in the known vacuum-assisted forming process of the matrix machine, it is necessary to adjust the appropriate vacuum degree according to different products. Usually, a line machine is equipped with a vacuum pump independently and the vacuum pump is adjusted by adjusting the speed of the vacuum pump through the frequency conversion control cabinet. It is necessary to configure a line machine. The investment cost of the vacuum pump and control cabinet is relatively high. In addition, since the vacuum pump has been in the non-economic operating speed range for a long time, the operating energy consumption is relatively high.
