Problems solved by technology

The most accurate known volumetric accuracy is of course the volumetric type, but there are other difficulties: one is that the gas must be strictly discharged in the glue path of the volumetric type, otherwise the gas will be compressed and the glue output will be affected; the other is how to miniaturize, It is convenient for cleaning and disassembly; the third is that the switching valve should be sealed and reliable, and easy to process

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Example.

[0014] see figure 1 , figure 2 , image 3 , the valve seat 001 is processed with A glue inlet, A glue cavity, B glue inlet, B glue cavity and the groove for installing the valve plate; the upper valve plate 002 is fixed on the bottom of the valve seat groove with AB glue , so as to eliminate gaps and prevent glue leakage, the four holes on the upper valve plate 002 correspond to the four holes on the valve seat 001 one by one, and the hole diameters are consistent; the switching valve plate 003 has a groove surface and pastes the valve plate 002, and the direction cannot be changed. Wrong; one side of the lower valve plate 004 is attached to the surface of the switching valve plate, and the direction cannot be wrong; two sealing rings 005 are placed in the holes of the slide valve fixing plate 006, and the surface should protrude t...

Abstract

The best way at present for AB glue super-small glue volume high precision dispensing consists of two screw rod valves, however domestic screw rod valve technologies are not mature, and how to replace becomes a problem. The invention provides a volume metering type AB glue sliding vane valve, and is used for switching glue replenishment and glue discharge.

Description

technical field [0001] The present invention relates to an AB glue volume metering dispensing switching valve, in particular to a sliding vane switching valve which is mainly composed of three pieces of plane seal, and the middle piece slides linearly to switch between replenishing glue and dispensing. . Background technique [0002] It is very important to mix AB glue according to the precise volume ratio. The highest precision abroad is composed of two screw valves of preeflow under ViscoTec in Germany. The two screw valves can be set at any speed corresponding to the mixing ratio of AB glue. The design, processing and material of this screw valve are very important, and the technology is monopolized, so it is necessary to find another way. The most accurate known volumetric accuracy is of course the volumetric type, but there are other difficulties: one is that the gas must be strictly discharged in the glue path of the volumetric type, otherwise the gas will be compress...
