Abstract

The utility model discloses a color paste adding device for a high-pressure foaming machine, which is provided with a controller, a mixer, a gun head and two or more than two raw material tanks, wherein the gun head is connected with the mixer in an output mode, and the raw material tanks are connected with the mixer in an input mode. The color paste adding device is provided with more than one color paste tank in different colors, the color paste tanks in different colors are communicated to mixed gas through a pneumatic pump, a pipeline switching valve and a metering pump and switched directly by automatic control, and then corresponding color paste is directly delivered into the mixing gun head through a pipeline, so that products in various colors can be produced and the problem of producing a plurality of varieties and colors simultaneously is solved. Since the color paste and raw materials are injected after being subjected to high-pressure mixing in the mixing gun head, environment protection is favored, the density and color of the products are more even, and quality requirement for high-end products can be met.

Description

The mill base adding set of high pressure foaming machine

Technical field

The utility model relates to a kind of former materials device, relates in particular to a kind of polyurethane high pressure foaming machine carries out additive color to the draw drum color when making the vehicle steering production of producing different colours device that is applied to.

Background technology

When tradition adopts the polyurethane high pressure foaming machine to make the vehicle steering of different colours, general all is the mill base that stirring mixes up directly to be added in the polyurethane high pressure foaming machine head tank to mix with raw material then be transported in the rifle head by pipeline, and weak point is that such addition manner need unclamp the bolt of head tank and open the raw material cover; In addition when changing another color behind the steering wheel of having produced a kind of color, need to clean whole head tank and pipeline, complex procedures and have a strong impact on production efficiency and delivery date.

Summary of the invention

In view of the defective that above-mentioned prior art exists, the purpose of this utility model is the mill base adding set that proposes a kind of high pressure foaming machine, to satisfy the needs of the automobile draw drum of producing multiple color, pursues low energy consumption production efficient, environmental protection.

Technical solution of the present utility model is: a kind of mill base adding set of high pressure foaming machine, described high pressure foaming machine has rifle head that controller, blender, blender output links to each other and the two or more head tanks that link to each other with its input, wherein, described mill base adding set has the mill base jar of an above different colours, and each mill base jar directly is communicated among the gaseous mixture by air driven pump, pipeline transfer valve and measuring pump.

Preferably, described measuring pump is the gear type measuring pump of VFC, and its control input end links to each other with controller; In addition, described each mill base jar input is connected with compressed air cylinder, and described air driven pump is located on the pipeline that both link to each other, and the control input end of air driven pump links to each other with controller.

The mill base adding set of this high pressure foaming machine that the utility model provides, directly switch by automatic control, its corresponding mill base will directly be delivered in the hybrid gun head by pipeline, so just can produce the product of multiple color simultaneously, has solved the difficult problem that many kinds, many colors are produced simultaneously.In view of mill base, raw material mix the back injection at the mixing head inner high voltage, not only help environmental protection, and the density of product and color are more even, can satisfy the quality requirement of high-end product.

Description of drawings

Fig. 1 is the syndeton schematic diagram of the utility model high pressure foaming machine mill base adding set.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.

As shown in Figure 1, the structure of high pressure foaming machine comprises controller, blender 2, rifle head 3 that links to each other with blender output and the two or more head tanks that link to each other with its input, be head tank 41 that contains PPG and the head tank 42 that contains isocyanates in the present embodiment, and its mill base adding set is totally independent of the above-mentioned raw materials jar, mill base jar with an above different colours, each mill base jar 11 is by air driven pump 5, pipeline transfer valve 12 and measuring pump 13 directly are communicated among the blender 2, and the color after the different tonings took place in blender with only mixing of raw material.

Particularly, one side of mill base agitator tank 11 can connect compressed air cylinder 6 by air driven pump of shared connection 5, opposite side then converges by pipeline transfer valve 12 and outputs among the blender 2, and the control input end of air driven pump 5 link to each other with controller (not shown), press in the output of the switch size regulation and control different colours by regulating air driven pump, and by the 12 regulation and control different colours outputs of pipeline transfer valve.

Especially, this mill base adding set leads at it that design has the full-bodied gear wheel metering pump of low discharge in pipeline of blender, can export different flows as required by Frequency Converter Control, adopt full-bodied air driven pump when adding mill base, control according to the signal that has liquid level sensor on the mill base jar and add the mill base demand in the mill base jar., towards the external touch-screen input control signal of controller mill base is delivered directly in the foaming machine blender by pipeline in the mill base jar by controller, in blender, fully mixes the back with various raw materials and produce by the injection of rifle head.

The application of utility model can directly be transported to mill base in the filling gun head by pipeline, has improved production efficiency and quality of item.When producing the automobile draw drum of multiple color, as long as the device of component mill base unit directly will be housed, directly switch by automatic control, its corresponding mill base will directly be delivered in the hybrid gun head by pipeline, so just can produce the product of multiple color simultaneously, solve the difficult problem that many kinds, many colors are produced simultaneously.Because mill base, raw material mix the back injection at the mixing head inner high voltage, not only help environmental protection, and the density of product and color are more even, can satisfy the quality requirement of high-end product.
