A solenoid valve for smd inductance packaging machine

Abstract

The invention discloses a solenoid valve for an SMD (Surface Mount Device) inductive packing machine. The solenoid valve comprises a connecting pipe, wherein a threaded seat in which a quadrate grooveis formed is arranged on the upper surface of the connecting pipe; a quadrate seat is in sliding connection with the inside of the quadrate groove; a housing is fixedly connected to the upper surfaceof the quadrate seat; a connecting plate is fixedly connected to the inner center of the housing; a fixed iron barrel is fixedly connected into the connecting plate; a threaded hole is formed in theupper surface of the fixed iron barrel, and a threaded rod is in thread connection with the inner part of the threaded hole; a tensioning plate is rotatably connected to the lower surface of the threaded rod through a rotating hole; a tensioning spring is fixedly connected to the lower surface of the tensioning plate; a movable iron core is fixedly connected to the lower surface of the tensioningspring through an avoiding groove, and a sealing block is fixed to the lower surface of the movable iron core through a connecting hole. With the adoption of the solenoid valve for the SMD inductive packing machine, the convenience of use of the solenoid valve is greatly improved; the electricity is saved; and the cost is decreased.

Description

technical field [0001] The invention relates to the technical field of electromagnetic valves, in particular to an electromagnetic valve used in an SMD inductive packaging machine. Background technique [0002] When packaging SMD inductors, a tape machine is generally used for packaging, and in order to ensure the efficiency of the packaging, it is necessary to use a solenoid valve for control to achieve automatic assurance, but the tape machine needs to be debugged before packaging, so that To determine the working state and connection position of the solenoid valve, but the existing battery valves are basically fixedly installed on the connecting pipe, and the angle of the solenoid valve cannot be placed according to actual needs, which is likely to cause interference and cause installation failure. Another is that the solenoid valve needs to be kept powered on before it can be opened or closed, and the state cannot be manually adjusted. If the debugging time is too long, ...

[0002] When packaging SMD inductors, a tape machine is generally used for packaging, and in order to ensure the efficiency of the packaging, it is necessary to use a solenoid valve for control to achieve automatic assurance, but the tape machine needs to be debugged before packaging, so that To determine the working state and connection position of the solenoid valve, but the existing battery valves are basically fixedly installed on the connecting pipe, and the angle of the solenoid valve cannot be placed according to actual needs, which is likely to cause interference and cause installation failure. Another is that the solenoid valve needs to be kept powered on before it can be opened or closed, and the state cannot be manually adjusted. If the debugging time is too long, it will cause waste of power. In addition, the coil direction of the solenoid valve is easy to be confused, causing the current direction to be wrong. But can not be used, not easy to adjust the use
