A kind of steering valve used in pneumatic device of glass cutting machine

Abstract

The invention relates to a conversion valve used for a glass cutting machine pneumatic device. The conversion valve comprises a valve body, a suction and exhaust opening is formed in the valve body, a first pipe joint, a second pipe joint and a third pipe joint are further formed in the valve body, and the first pipe joint and the second pipe joint are symmetrically arranged on the side wall of the valve body; a rotating shaft is transversely arranged in the valve body, the two ends of the rotating shaft penetrate the side wall of the valve body, a baffle is connected to the position, located inside the valve body, on the rotating shaft, and when the rotating shaft rotates, the baffle and the first pipe joint are in shielded fit or the baffle and the second pipe joint are in shielded fit; and a pedal plate is connected to the position, located on one side of the valve body, of the rotating shaft, and the position, located on the other side of the valve body, of the rotating shaft is connected to the valve body through a tension spring. The conversion valve has the beneficial effects that the aim that one draught fan controls a glass cutting machine to perform sucking and blowing at the same time is achieved through the conversion valve, the number of pipelines of the whole machine is reduced, the structure is simple, routing is simple, assembling is convenient, and the cost is low.

Description

technical field [0001] The invention relates to a glass machine, in particular to a steering valve used in the pneumatic device of a glass cutting machine. Background technique [0002] When manufacturing glass, cutting glass is a very important process. At present, for glass cutting, manual cutting and mechanical cutting are usually used. The cutting efficiency of manual cutting is low, and due to manual operation, cutting errors are prone to occur, resulting in flakes The glass is damaged and resources are wasted, so most of the glass manufacturers currently use glass cutting machines for cutting, but the existing glass cutting machines use two sets of independent exhaust devices when the glass is fixed and removed. There are many pipelines, complex wiring, troublesome assembly, and troublesome control of the two sets of devices, and the cost is high. In order to solve the above technical problems, the applicant designed a pneumatic device for a glass cutting machine. This...
