Full-automatic distributing and conveying appliance of plastic-rubber raw materials

Abstract

The invention relates to a fully-automatic distributing and conveying appliance of plastic-rubber raw materials, which is used for conveying various raw materials to a plurality of molding host machines respectively, and comprises a main transfer pipe, a plurality of feeding three-way changeover valves, a plurality of discharging three-way changeover valves, a plurality of feeding branch pipes, a plurality of discharging branch pipes, and PLC control systems. The plurality of feeding three-way changeover valves and the plurality of discharging three-way changeover valves are orderly arranged in series on the main transfer pipe, each feeding branch pipe is connected and communicated with a third opening of one feeding three-way changeover valve respectively; one end of each discharging branch pipe is connected and communicated with a third opening of one discharging three-way changeover valve respectively, and the other end of each discharging branch pipe is connected and communicated with one molding host machine respectively, the PLC control systems control the actions of the plurality of molding host machines, the plurality of feeding three-way changeover valves and the plurality of discharging three-way changeover valves respectively. Because the appliance adopts the novel three-way changeover valves and the PLC for control, the production efficiency is greatly improved; and the three-way changeover valve in the invention has the advantages of small overall dimension, compact structure, and easy operation.

Description

technical field [0001] The invention relates to a valve, in particular to a fully automatic distributing and conveying device for rubber and plastic raw materials. Background technique [0002] In the rubber and plastic auxiliary machinery industry, the corresponding relationship between various raw materials and multiple hosts is often not fixed, and the phenomenon of multi-directional transportation is very common. In order to solve the problem of multi-directional transportation, in actual production, manual switching is often used, which we commonly call "distribution plate". The principle of the distribution plate is to add multiple branch pipes on a main pipe and place all the branch pipes together. In this case, labor only needs to be concentrated in one place to switch raw materials. Since the distribution plate does not adopt the principle of automatic switching, it can only be switched manually, which is easy to cause misoperation, and residual raw materials are ...

AI Technical Summary

Problems solved by technology

The problems of this kind of switching valve are: 1. The purpose of switching is achieved by moving the tube, so the connecting tube to be moved must be a hose

During the transportation process, the more joints between the hose and the hard pipe, the easier it is to produce material residue; 2. Since the connecting pipe needs to be moved, it cannot be used in the automatic distribution tray; 3. Since the valve body needs to be provided with two holes, the The external dimension of the switching valve is relatively large; 4. Since the valve body is made of thick plates, if stainless steel is used, the cost is high; if carbon steel is used, it is easy to rust and cause defective products

[0004] Other switching valves, such as copper ball valves, V-shaped valves, etc., are too expensive to be widely used in this industry
