Problems solved by technology

[0004] 1. It is troublesome to use. You need to shake the tank for at least one minute each time you use it
[0005] 2. There is 5-6kg / cm2 in the polyurethane foam caulking agent tank 2 (25°C) pressure, the polyurethane foam sealant in the tank is discharged during use, the pressure in the tank will gradually decrease, and finally some unused polyurethane foam sealant will remain in the tank due to insufficient pressure. Long-term accumulation, resulting in a lot of waste

Embodiment 1

[0028] Embodiment 1, the present invention provides a kind of mixing device, see Figure 1-Figure 3 , comprising a main frame 11 and a filling gun 16, said main frame is provided with at least two feed ports 12 and feed ports 121, a feeding device 13 and a feeding device connected to the feed ports 12 and the feed ports 121 respectively Device 131, air compressor 14 and the electrical control system 15 that is connected with feeding device and air compressor; Described filling gun comprises filling gun body 161, and described filling gun body is provided with two material inlets 162 and material feeding The mouth 1621, the nozzle 163 communicated with the feed port 162 and the feed port 1621 and the return port 164 and the return port 1641 that are respectively matched with the feed port 162 and the feed port 1621, the return port 164 and the return port 1641 are connected to the A piston 165 is provided between the feed port 162 and the feed port 1621, the piston is connected...

Embodiment 2

[0034] Embodiment 2, on the basis of Embodiment 1, the applicant has also made the following design, see Figure 5, the feed inlet 162 and the feed inlet 1621 are horizontally equipped with reinforcing columns 19, and a plurality of half-spiral sheets 191 are installed at transverse intervals on the reinforcement columns. The half-spiral sheets described here are half of the spiral sheets, and That is, half of the reinforcing column in the figure is installed with a spiral piece. It can be understood that the spiral piece on one side is removed after the reinforcing column is installed with a spiral piece. On one side of the air inlet, the tail end (ie, the end end) is located on one side of the nozzle. In this structure, after raw material A and raw material B are sent to the feeding port 162 and feeding port 1621 of the filling gun through the feeding device, When the two flow through the reinforced column respectively, they are dispersed by the reinforced column and the hal...

Embodiment 3

[0035] Embodiment 3, on the basis of Embodiment 2, the applicant also made the following design, see Image 6 , the feed port 162 and the feed port 1621 are provided with a groove 20 on one side near the air inlet, and the groove is located on the outside of the reinforcing column; the side of the groove near the piston is inclined Yes, the inclination angle can generally be set to 30-60 degrees, the vertical distance L1 from the end close to the nozzle to the piston is smaller than the vertical distance L2 from the end far away from the nozzle to the piston; an elastic diaphragm 201 is installed in the groove, and the elastic diaphragm If it is inclined, the inclination angle can generally be set to 30-60 degrees, and the vertical distance from the end of the elastic diaphragm close to the reinforcing column to the shower head is greater than the vertical distance from the end of the elastic diaphragm far away from the reinforcing column to the shower head. This structure is ...

Abstract

The invention provides a mixing device. The mixing device comprises a main rack, wherein at least two charging openings, feeding devices, an air compressor and an electrical control system are arranged on the main rack, the feeding devices are separately connected with the charging openings, and the electrical control system is connected with the feeding devices and the air compressor. According to the mixing device provided by the invention, the use is convenient, and raw materials are saved.

Description

technical field [0001] The invention relates to the field of caulk production equipment, in particular to a mixing device. Background technique [0002] Polyurethane foam caulk is a one-component, moisture-curing, multi-purpose polyurethane foam-filled elastic sealing material. Polyurethane foam sealant is a special polyurethane product filled with polyurethane prepolymer, foaming agent, catalyst and other components in a pressure-resistant aerosol can. During construction, the aerosol colloid is sprayed to the site to be constructed through a matching sizing gun or manual nozzle, and the forming, foaming, bonding and sealing processes are completed in a short period of time. Its cured foam elastomer has excellent properties such as bonding, waterproof, thermal expansion and contraction resistance, heat insulation, sound insulation and even flame retardant (limited to flame retardant type), and is widely used in the filling of building door and window side seams, component ...
