Abstract

The utility model relates to a polyurethane foaming device, and in particular to a mixing device for manually foaming the polyurethane, which comprises a frame-shaped bracket, a mixing barrel with a barrel cover being fixed on a bottom beam, an agitating vane that is arranged inside the mixing barrel and a motor that is connected with the agitating vane through a transmission shaft, wherein, the motor is fixed on a beam inside the bracket, and is characterized in that the outer wall of the bracket is provided with a limit device; the barrel cover of the mixing barrel is provided with a small cover that is convenient to be opened, and the barrel cover is connected with the barrel wall in a disassembling way; the barrel bottom consists of two parts that are hinged with the barrel wall through two hinges, and each hinge is connected with a pneumatic or hydraulic mechanism that is arranged on the outer side of the barrel wall; the device can uniformly mix the material, and is convenient to discharge the material, and can effectively reduce the waste of the materials, and is free from particular requirements on the mould.

Description

A kind of polyurethane foaming agitating device

One, technical field

The utility model relates to a kind of polyurethane foaming agitating device, the agitating device of the manual foaming of especially a kind of polyurethane usefulness.

Two, background technology

The polyurethane foam process, be that A material and B material are mixed, the process that chemical reaction generates foaming product takes place, foam device generally is divided into the foaming machine and the manual foam device of automation, in high pressure foaming machine and low pressure foaming machine, being blended in of two kinds of raw materials finished in the mixing head; In the manual foam device, the mixing of two kinds of raw materials is normally finished in agitating device, agitating device commonly used mainly is end driven type agitator and two kinds of formula agitators of the no end, the former be with mixing of materials evenly after, pour into the foaming mould from the suitable for reading of agitator, mixed material easily sticks on barrel wall, causes waste; The latter is placed directly in the agitator at the no end in the foaming mould, after mixing of materials in the bucket is even, by the support that is connected the bucket top agitator is risen, mixed material in the bucket just directly leaks in mould, though it can reduce the waste of raw material, but, formula agitator of the no end need with the bottom surface close fit of mould, could form a container, making required precision to mould is higher, will certainly increase the processing charges of mould, leaks from poor fit otherwise just have raw material, it is uneven to cause raw material to mix, and influences foaming effect.

Three, summary of the invention

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, provides a kind of and stir, reduce the material waste, do not increase the polyurethane foaming agitating device of die cost.

For achieving the above object, the technical solution adopted in the utility model is, a kind of polyurethane foaming agitating device, comprise that frame support that back timber can be connected with crane and bung are fixed in agitator on its bottom girder, place stirring arm in the bucket and the motor that is connected with stirring arm by power transmission shaft, motor is fixedly mounted on the interior crossbeam of support, its special character is, on the outer wall of support stopping means is housed; The bung of agitator is provided with the tegillum that can conveniently open, and bung is dismountable being connected with the bucket wall; Bucket forms by dock with the hinged two parts of bucket wall respectively at the end, each hinge each with a cover be installed in barrel wall outside upward pneumatic or hydraulic mechanism be connected.

The good effect that compared with the prior art the utility model has is, at the bottom of itself carrying barrel, do not need to cooperate with mould, can not increase the manufacturing cost of mould; Unique bucket end design is opened the back mixed material and is directly poured into the foaming mould from the bottom, can effectively reduce the waste that material causes because of adhesion, and modern design is rational in infrastructure, convenient and practical.

Four, description of drawings

Fig. 1 is the schematic diagram of agitator of the present utility model under closed condition at the bottom of the bucket.

Fig. 2 is the schematic diagram of agitator of the present utility model under open mode at the bottom of the bucket.

Five, the specific embodiment

For better understanding the utility model, it is done explanation in further detail below in conjunction with drawings and Examples.

As shown in Figure 1 and Figure 2, polyurethane foaming agitating device foam device described in the utility model is made of frame support 31, motor 32, power transmission shaft 33, paddle 34, agitator 35, bung 36, the bucket end 37 and pneumatic or hydraulic mechanism 38, the back timber of support 31 can be connected with crane, be used for promoting agitator, the bottom girder of support 31 is fixedlyed connected with the bung 36 of agitator 35, bung is to adopt bolt for convenience detach or hasp to be connected with the bucket wall, bung is provided with the tegillum that can conveniently open, so that to ladle addition; Motor 32 is on the crossbeam 30 that is fixedly mounted in the support 31, and stopping means 39 is housed on the outer wall of support 31, is used to prevent that support 31 from planar rotating; Be built-in with stirring arm 34 at agitator 35, stirring arm 34 is in transmission connection by power transmission shaft 33 and motor 32; Bucket is divided into two lobes in the end 37, and every lobe links together with hinge with the bucket wall respectively, and each is installed in each hinge a barrel wall outside with a cover and goes up pneumatic or hydraulic mechanism is connected, so that realize opening and closing of barrel end.

During use, can be at the inboard attached lining polybag of bucket wall, to avoid a barrel wall adhered materials, cut the waste and be convenient to clear up agitator; Lay one deck elaxtic seal at the bottom of the bucket, after closing with an assurance bucket end, agitator can not produce Lou material, makes mixing of materials even, improves foaming quality.

Claims

1, a kind of polyurethane foaming agitating device, comprise that frame support (31) that back timber can be connected with crane and bung are fixed in agitator (35) on its bottom girder, place stirring arm (34) in the bucket and the motor (32) that is connected with stirring arm by power transmission shaft (33), motor (32) is fixedly mounted on the crossbeam (30) of support (31), it is characterized in that: stopping means (39) is housed on the outer wall of support (31); Be provided with the tegillum that can conveniently open on the bung of agitator, bung is dismountable being connected with the bucket wall; Bucket forms by dock with the hinged two parts of bucket wall respectively at the end, each hinge each with a cover be installed in barrel wall outside upward pneumatic or hydraulic mechanism be connected.
