In the copolymerization reaction, emulsification and post-treatment, fluid substances need to be quantitatively proportioned. In order to improve the accuracy of proportioning and the convenience of feeding, an automatic quantitative feeding equipment suitable for oil-proof agent production needs to be developed. SUMMARY

[0003] The utility model provides a kind of quantitative feeding device for oil-proof agent processing;Solve the problem that multiple fluids need to be quantitatively proportioned in the production process of oil-proof agent in the prior art.

[0005] The inlet of the utility model is communicated with the barrel, and the ball valve controller is used to control the state of the three-way ball valve. The quantitative feeding principle of the utility model is as follows: the ball valve controller first switches the three-way ball valve to the state of connecting the inlet and the quantitative port, then the injection cylinder drives the piston to move backward, the negative pressure generated in the measuring cylinder will generate suction, thereby sucking the fluid in the barrel, then the three-way ball valve is switched to the state of connecting the discharge port and the quantitative port, then the injection cylinder drives the piston to move forward, the positive pressure generated in the measuring cylinder will generate thrust, thereby discharging the fluid in the measuring cylinder from the discharge port. Therefore, the volume of fluid discharged each time is related to the reciprocating stroke of the injection cylinder, and the stroke of the injection cylinder is determined by the distance between the sliding limit block and the fixed limit block. Therefore, the feeding amount of fluid material can be adjusted by adjusting the position of the fixed limit block.

[0006] Although theoretically the piston, piston rod, connecting rod and cylinder rod of the injection cylinder are coaxial, but due to the influence of installation accuracy, there is a certain range of eccentricity in practice, therefore, in order to prevent the eccentricity during the extension and contraction of the injection cylinder from causing the deformation and misplacement of the fittings, the utility model specially sets a ball head connection between the limiting plate and the connecting rod, so that the whole transmission assembly can deflect within a certain range.

Through the above technical scheme, when the adjusting screw of the utility model is loosened, the movable block loses the extrusion of the adjusting screw, so that the movable block and the protrusion no longer tightly fit with the two clamping grooves, at this time, the slide limiting block can freely slide relative to the slide rail, after the position is adjusted, the adjusting screw is tightened again, at this time, the movable block and the protrusion again tightly fit with the two clamping grooves, and the static friction force can completely fix the slide limiting block and the slide rail. Such an adjusting mode is simple and fast, the adjusting screw actually abuts against the movable block, the contact area of the movable block and the clamping groove is larger, the slide rail is not easy to be abraded, and the precision of the slide rail can be maintained.

[0008] As preferred, the top surface of the slide rail is provided with a groove, and the scale line is arranged in the groove, so that the scale line can be avoided from being abraded.
