Abstract
The utility model discloses a mixing device of a foaming machine for polyurethane for leatheroid. The utility model comprises a stirring mixing cylinder, a solvent barrel, and two or more than two raw material barrels, wherein the raw material barrel is connected with the bottom of the mixing cylinder by a material feeding pipe, the upper part of the mixing cylinder is provided with a mixture material discharging opening, the bottom is provided with a tail material discharging opening and a variable frequency speed control transfer gear pump is arranged between each raw material barrel and the mixing cylinder on which a stirring mechanism is also arranged. The transfer gear pump is connected with a variable frequency speed control electric machine. The stirring mechanism comprises a stirring speed control electric machine arranged at the top of the stirring mixing cylinder in which a stirring paddle is arranged. The stirring speed control electric machine is coaxially connected with the stirring paddle. The utility model uses the adjustable variable frequency electric machine to drive the variable frequency speed control transfer gear pump, which leads an original plunger type piston pump to be replaced.

Description
Technical field
The utility model relates to a kind of mixing arrangement of polyurethane foaming machine, especially a kind of mixing arrangement of used for artificial leather polyurethane foaming machine.
Background technology
In existing polyurethane foaming machine technology, the mixing arrangement of used for artificial leather polyurethane foaming machine generally adopts the mechanism of piston metering feeding, pressure-air rapid mixing.Raw material pail is connected with mixed cylinder by feed pipe, and feed pipe is provided with the plunger type piston type dosing pump, and raw material is made back and forth movement by the piston in the piston pump and is pumped in the mixed cylinder.The pump chamber of the piston pump of this mechanism can also be as the measurement unit of raw material conveying except the effect of material stock, feeding is arranged.Mixed cylinder is provided with the gases at high pressure spray gun, by gases at high pressure the raw material in the sealing mixed cylinder is sprayed, and makes the raw material in the cylinder not stop to stir under the effect of gases at high pressure, reaches the purpose that nature mixes.But the plunger type piston type dosing pump because the friction between piston and pump chamber makes piston wear, raw material can occur and reflux in use for some time when pumping raw material.And the material viscosity of used for artificial leather polyurethane is bigger, and is strong to the adhesiveness of pump chamber wall, can increase the suffered frictional force of piston in the piston pump use, the wearing and tearing of accelerating piston, so the raw material backflow phenomenon appears in plunger type piston pump easily, the poor accuracy of metering, and service life is short.In addition, because backflow phenomenon appears in used for artificial leather polyurethane raw material, occurring raw material easily when carrying out the gases at high pressure mixing stirs undesirable, mix inhomogeneous, cause the material homogeneity that blends poor, directly influence the quality of product in the production, and the bigger component of viscosity makes the cleaning of mixed cylinder more difficult easily mixing bonding.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, and the mixing arrangement of the used for artificial leather polyurethane foaming machine of a kind of stability of flow, accurate measurement, good mixing effect, long service life is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mixing arrangement of used for artificial leather polyurethane foaming machine, comprise and mix cylinder, solvent barrel, two or more Raw material pails, Raw material pail by feed pipe with mix cylinder bottom portion and be connected, mix cylinder top and be provided with the mixture discharge gate, the bottom is provided with tailing row mouth, its architectural feature is each Raw material pail and mixes and all be provided with frequency control gear delivery pump between the cylinder, mixes and also be provided with rabbling mechanism on the cylinder.
Described gear delivery pump is connected with frequency control motor.Described rabbling mechanism comprises and is arranged on the stirring buncher that mixes the cylinder top, mixes cylinder interior and is provided with paddle, stirs buncher and is connected with paddle is coaxial.Paddle can be propeller type, flat straight oar formula, hinged joint oar formula, anchor formula or frame, is divided into two-nine layers, and the levels paddle is staggered to be fixed on the shaft.
The beneficial effects of the utility model are: improve by the mixing arrangement to traditional used for artificial leather polyurethane foaming machine, the utility model replaces original plunger type piston pump with the frequency control gear delivery pump that adjustable variable-frequency motor drives, because variable-frequency motor can be adjusted the rotating speed of frequency control delivery pump according to the raw material of different viscosities, and raw material is lower than plunger type piston pump to the friction of frequency control delivery pump, the high viscosity component is also little than plunger type piston pump to the wearing and tearing of the pump housing, so the flow of frequency control delivery pump is more stable, flow-control is more accurate, the longer service life of pump.In addition, utilize the mixing of stirring buncher drive paddle to replace original gases at high pressure upset to mix, two kinds of bigger raw material components of viscosity differences can fully be mixed under the effect of paddle, mixed effect is better, the material that blends is more even, and the component that viscosity is bigger is difficult in that to mix cylinder bottom bonding.
