The proportioning device of can packing machine
The utility model relates to high viscosity coating (lotion or liquid) from the canned a kind of can packing machine to coating packing bucket (hereinafter referred to as paint can) of stirred tank.
High viscosity coating from stirred tank out after, need through can packing machine canned in paint can.Can packing machine forms T-shaped by proportioning device and vertical pipeline and forms.Proportioning device is wherein, install piston cylinder in the outer end of plunger cylinder (hereinafter referred to as cylinder) piston rod, piston cylinder runs in cylinder barrel, and cylinder and cylinder barrel are word order, are separately fixed on base.Cylinder barrel is connected with vertical pipeline by threeway, and vertical pipeline is feed pipe, threeway main pipeline and discharge pipe from top to bottom successively, and the other pipeline of threeway is connected with cylinder barrel.When discharge pipe valve closing, feed pipe valve open, air cylinder driven piston cylinder is dropped back, and under suction function, high viscosity coating is inhaled into cylinder barrel by threeway; When feed pipe valve closing, discharge pipe valve open, air cylinder driven piston cylinder advances, and high viscosity coating is pushed three and passes to discharge pipe, until paint can.Because the viscosity of coating is high, the load that cylinder and cylinder barrel bear is comparatively large, and cylinder and cylinder barrel are again be separately fixed on base, when proportioning device runs, cylinder and cylinder barrel at least one can shake, and then can there is relative displacement in cylinder and cylinder barrel, cause cylinder and cylinder barrel disalignment.Continue to run, piston rod can deform, and causes can packing machine normally to work.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of proportioning device of can packing machine.
The purpose of this utility model is achieved in that it comprises cylinder, cylinder barrel and base, it is characterized in that: at least three concentric welded flanges are arranged on base, and two welded flanges are wherein arranged on cylinder barrel, and remaining welded flange is installed on cylinder; Each flange has three eyelets at least, and three flanges are strained through the screw hole that three flanges are corresponding by the screw rod of each band nut simultaneously.Cylinder and cylinder barrel tension are integrated by such three welded flanges, are fixed on base.
Compared with prior art, good effect of the present utility model is: remain cylinder barrel and cylinder coaxial, extends the service life of can packing machine, and pulling force have also been obtained and improves significantly simultaneously.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
It comprises cylinder 1, cylinder barrel 4 and base 6, three concentric welded flanges 2 and is fixed on base, and two welded flanges are wherein arranged on cylinder barrel, and remaining welded flange is installed on cylinder; Each flange has four eyelets, and three flanges are strained through the screw hole that three flanges are corresponding by the screw rod 5 of each band nut simultaneously.Cylinder and cylinder barrel tension are integrated by such three welded flanges, are fixed on base.3 is erecting frames of can packing machine.
Concentric flange can also be four, and cylinder and cylinder barrel respectively install two flanges.Flange is more, and alignment is better.
