Abstract

The utility model relates to a foaming machine which is composed of a batch can device and a gun head device. A temperature sensor and a heater unit are arranged in a batch can of the batch can device, the upper part of the batch can is communicated with a compressed air pipeline, and the lower part of a pressure can is communicated with a conveying pipe. A gun head inlet of the gun head device is communicated with the conveying pipe, the compressed air pipeline and a small air pipe, and the position of the compressed air pipeline entering a gun head is provided with a rotating piece. The gun head can not be clogged when works, and only a gun barrel needs to be replaced when an operation is processed.

Description

Foaming machine

The utility model relates to a kind of foaming machine, is mainly used in the manufacturing polyurethane and hard bubbles.

Polyurethane hard bubbles and has excellent insulation, thermal insulation, waterproof and antiseptic property, is one of material that thermal conductivity factor is minimum in the insulation material, has become the first-selected insulation material of various countries, world today heating power, air-conditioning, oil transportation thermal car, boats and ships, railway carriage and freezer.

Prior art is to be clamp-oned in the rifle head by the motor-driven screw feeding device raw material that will hard bubble, and mixes and extrusion molding through motor-driven screw feeding device again.Its weak point is: the rifle head stops up easily; Operation is complicated.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides that a kind of rifle head can not stop up, the simple foaming machine of Operation and maintenance.

The purpose of this utility model can reach by following measure: the utility model is made up of batch can device and rifle head unit, temperature sensor and warm-air drier are arranged in the batch can of batch can device, the batch can top is communicated with compressed air piping, press a jar bottom to be communicated with feed pipe, the rifle head import of rifle head unit is communicated with feed pipe, compressed air piping and tracheole, and compressed air piping enters rifle head place revolving fragment.

Air gauge is arranged on the batch can.

Be connected with pressure-reducing valve and check valve on the compressed air piping of head tank.

Batch can places on the handcart.

On the feed pipe of rifle head unit, compressed air piping and the tracheole fixed mount is arranged, fixed mount tightens together feed pipe and compressed air piping.

The ball valve that the band joystick is arranged on the compressed air piping.

The rifle head port of export is communicated with gun barrel.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a general arrangement of the present utility model;

Fig. 2 is the figure of the utility model batch can device;

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 represents general structure of the present utility model, form by batch can device 1 and rifle head unit 2,3 two of batch cans that store white material and black material respectively place on the handcart 4, there is air duct 10 that compressed air is sent into respectively in two batch cans, the white material and the black material that extrude in the batch can enter respectively in the rifle head 5, also have air duct that compressed air is sent into the rifle head, through mixing to make the goods that hard bubble.

Fig. 2 and Fig. 3 represent the structure of batch can device, cover 6 on the batch can, air gauge 7 are housed to show the batch can internal gas pressure on the batch can.Temperature sensor 8 and warm-air drier 9 are arranged at the batch can bottom, and winter, temperature sensor can start warm-air drier automatically when cold, material in the jar are heated, to guarantee still to make batch can continue operation under the microthermal climate.On compressed air piping, be in series with pressure-reducing valve 11 and check valve 12, also be communicated with vent valve 13 in two outer ends, supply and demand will the time open the usefulness of vent valve with emptying.Feed pipe 14 is arranged at batch can bottom, by the batch can compressed air respectively the black material and the white material that go out of force feed enter rifle head 5 (seeing Fig. 4 and Fig. 5) respectively, also have an independent compressed air piping 15 to carry compressed air to enter the rifle head.

Fig. 4 and Fig. 5 represent the structure of rifle head unit, have fixed mount 16 that two feed pipes and a compressed air piping are fixed together, and the ball valve 20 and the control handgrip 17 of control tolerance arranged on the compressed air piping.Two feed pipes 14 are equipped with the set screw of regulating black, white materials flow amount respectively on the pipeline that enters before the rifle head 5.Enter rifle head 5 places at compressed air piping air-flow revolving fragment 18 is housed.

Fig. 6 and Fig. 7 represent the structure of revolving fragment, and the boring drill bit of the global shape of revolving fragment 18 such as metal is perhaps like edible fried dough twist.Compressed air stream makes the air-flow that enters the rifle head be the rotation shape by revolving fragment to advance, will deceiving material and white material is fully mixed to evenly, after gun barrel 19 outputs obtain the manufactured goods polyurethane and hard bubble.

The unlikely obstruction discharging of the black and white material mouth of pipe in order to prevent to come out from feed pipe in the rifle head is provided with two tracheoles 21 at the back side of rifle head (seeing Fig. 4 and shown in Figure 5) and enters, and tracheole can blow down the material that will block the discharging mouth of pipe at any time.

The utility model contrast prior art has following advantage:

Can not stop up during the operation of rifle head; Only need change gun barrel during operation gets final product.
