Problems solved by technology

Due to the inconvenience of movement, the use is very limited and the scope of use is very small. Basically, it is a special equipment in some kind of production and processing process.
Most of the feeding methods use a motor combined with a gear box to directly drive the charging pump to run and feed. The selection of this feeding method makes the weight and volume of the foaming machine increase a lot, and the efficiency is low, and the power consumption is large. It produces a lot of useless work, requires a lot of other auxiliary equipment, the structure is relatively complicated, and maintenance is inconvenient

Embodiment 1

[0018] like figure 1 As shown, the schematic diagram of the working principle of the portable and heated polyurethane foaming machine includes a walking device, a feed heating device (including a feed heating device 300 and a feed heating device 400, which are used to heat raw material B and raw material A respectively), two-way Cylinder and upper pressurized cylinder group 100 and lower pressurized cylinder group 200, described upper pressurized cylinder group 100 and lower pressurized cylinder group 200 are respectively connected with two power output ends of two-way cylinder, and described feed heating device is connected with The feed ports of the upper pressurized cylinder group 100 and the lower pressurized cylinder group 200 are connected.

[0019] Polyurethane raw materials are generally divided into two components: raw material A component (black material) isocyanate - polyphenyl polymethylene polyisocyanate. Raw material B component (white material) is combined with...

Embodiment 2

[0022] like figure 2 Shown is a schematic structural view of the feed heating device (taking the feed heating device 300 as an example), including a double-wire square spiral heating tube 301, a feeding tube 302, an insulation layer 303, a power interface 304, a feed port 305, a discharge Mouth 306; feed pipe 302 selects PPR pipe for use, and surrounds and arranges up and down in the feed heating device. The double-wire square spiral heating tube 301 is arranged circularly around the feeding pipe 302. The double-wire square spiral heating tube 301 is made of a copper tube shell. The inside of the double-wire square spiral heating tube 301 is provided with a resistance wire, and the external power supply interface 304 is connected to the power supply to provide electric energy. heating.

[0023] In order to make the heating uniform and lasting, the feed heating device is filled with saturated brine, because the brine has a low freezing point and is not easy to freeze. In add...

Embodiment 3

[0026] like image 3 Shown is a schematic structural view of the pressurized cylinder, including a piston rod 107 , a feed chamber 111 , a feed check valve 103 , a feed inlet 102 , a pressurized check valve 104 , a discharge chamber 110 , and a feed outlet 109 . The working principle of this booster cylinder is: two-way cylinder 14 (see Figure 4 ) power is output to the piston rod 107 through the extension shaft 10, thereby driving the piston rod 107 to reciprocate up and down. Driven by the two-way cylinder 14, when the piston rod 107 moves upward, the feed chamber 111 forms a vacuum and generates negative pressure. When the negative pressure reaches a certain level, the feed check valve 103 is opened by the negative pressure, and the raw material is discharged Port 102 sucks into feed chamber 111 . Since the spring force of the pressurized one-way valve 104 is relatively large, the raw material will not flow into the discharge chamber 110 through the pressurized one-way v...

Abstract

The invention discloses a portable heating-type polyurethane foaming machine which comprises a traveling device, a charging heating device, a bidirectional cylinder, an upper pressurized cylinder unit, and a lower pressurized cylinder unit; the upper pressurized cylinder unit and the lower pressurized cylinder unit are connected to two power output ends of the bidirectional cylinder respectively;the charging heating device is connected to feed inlets of the upper pressurized cylinder unit and the lower pressurized cylinder unit; and both the upper pressurized cylinder unit and the lower pressurized cylinder unit comprises two pressurized cylinders. Based on the disadvantages such as huge body, inconvenience of moving, small application scope, no auxiliary heating equipment, low efficiency, high energy consumption, long adjusting time and the like of existing foaming machines, the foaming machine of the invention is designed in view of portability, convenience of moving, large application scope, auxiliary heating, high efficiency, energy saving, time saving, and uniform charging.

Description

technical field [0001] The invention relates to a portable heating type polyurethane foaming machine, which belongs to the technical field of foaming. Background technique [0002] Foaming machine, also known as foam generator, is a device that can make a certain concentration of chemical raw materials into foam and condense into solid. The foaming machine mixes two different chemical raw materials evenly according to their respective proportions, and sprays them out under high pressure. After the mixed raw materials encounter air, a violent chemical reaction occurs to produce a large amount of foam, so that its volume increases rapidly. After a period of time, it is exposed to Mixed raw materials in the air condense into a solid with a lot of foam. [0003] Foaming machine can be used in light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, gas vehicles, national defense, aerospace, aviation, etc. Typical application...
