Description

Technical Field

[0001] This utility model relates to the field of foam gun technology, specifically to a foam gun for polyurethane foam materials. Background Technology

[0002] A foam gun is a tool used for sealing and filling gaps in doors and windows with foaming agents. The foam gun sprays foaming material to achieve functions such as installation, filling gaps, repairing leaks, and bonding. Therefore, it is widely used in the decoration industry. The foaming material is filled in a foaming material tank. The foaming material tube is installed on the foam gun so that the foam gun can spray out the foaming material.

[0003] Currently, single-component polyurethane foam sealant materials on the market suffer from problems during winter construction due to low temperatures. After spraying, the material fails to solidify, has a low expansion ratio, poor adhesion, and is prone to falling off, rendering it unusable. Additionally, the foam gun often leaves a large amount of sealant residue inside the barrel, causing blockage and hindering its operation. Therefore, we have proposed a foam gun specifically for polyurethane foam materials to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figures 1-3 As shown, an embodiment of this utility model discloses a foaming gun for polyurethane foam materials, including a foaming gun body 1. A control tube 2 is installed on the left side of the foaming gun body 1. A wrench 3 is provided on the control tube 2. An adapter 4 is installed on the upper surface of the control tube 2. A circular sleeve 6 is installed on the outer surface of the adapter 4 by means of a first fastening bolt 5. The first fastening bolt 5 is symmetrically arranged front and back. A first heating mechanism 7 is provided on the inner wall of the circular sleeve 6. A gun barrel 8 is threadedly installed on the left side of the control tube 2. A rectangular box 10 is installed on the outer surface of the gun barrel 8 by means of a second fastening bolt 9. Four second fastening bolts 9 are arranged front and back. A second heating mechanism 11 is provided in the rectangular box 10 at a position corresponding to the outer surface of the gun barrel 8. A control mechanism 12 is provided in the rectangular box 10 near the upper side. A cleaning mechanism 13 is installed in the rectangular box 10 near the right side. A nozzle 14 is installed on the left side of the gun barrel 8.

[0017] like Figure 2 As shown, in some embodiments, the upper and lower sides of the circular sleeve 6 are both open structures, and the circular sleeve 6 is fitted onto the outer surface of the adapter 4.

[0018] In this embodiment, the circular sleeve 6 can be installed on the outer surface of the adapter 4, and the openings at the top and bottom of the circular sleeve 6 facilitate the installation of the expanding foam bottle on the adapter 4.

[0019] like Figure 2As shown, in some embodiments, the first heating mechanism 7 includes an insulation sleeve 701, a heating wire 702, and an aluminum foil tape 703. The insulation sleeve 701 is installed on the inner wall of the circular sleeve 6. The heating wire 702 is disposed on the inner wall of the insulation sleeve 701, and the aluminum foil tape 703 is disposed on the inner wall of the heating wire 702.

[0020] In this embodiment, the heating wire 702 heats the foam bottle through the aluminum foil tape 703, which heats the foam inside the foam bottle, and the insulation sleeve 701 reduces heat loss.

[0021] like Figure 3 As shown, in some embodiments, the second heating mechanism 11 has the same structure as the first heating mechanism 7, and the second heating mechanism 11 is embedded in the left and right side walls of the rectangular box 10.

[0022] In this embodiment, the second heating mechanism 11 can heat the foam inside the gun barrel 8.

[0023] like Figure 3 As shown, in some embodiments, the control mechanism 12 includes a controller 121, a battery 122, a charging port 123, a temperature sensor 124, and a switch button 125. The controller 121, battery 122, charging port 123, and temperature sensor 124 are installed inside a rectangular box 10. The charging port 123 is embedded in the front side wall of the rectangular box 10. The temperature sensor 124 is embedded in the second heating mechanism 11. The switch button 125 is embedded on the upper surface of the rectangular box 10. The controller 121 is electrically connected to the battery 122, the temperature sensor 124, and the switch button 125.

[0024] In this embodiment, the charging port 123 charges the battery 122, and the switch button 125 is turned on so that the battery 122 supplies power to the first heating mechanism 7 and the second heating mechanism 11 through the controller 121. The temperature of the second heating mechanism 11 is monitored by the temperature sensor 124 and the information is fed back to the controller 121, which controls the heating temperature.

[0025] like Figure 2 and Figure 3 As shown, in some embodiments, the right side wall of the rectangular box 10 and the right side wall of the circular sleeve 6 are both provided with power connectors 15, and the power connectors 15 are electrically connected to each other by wires 16.

[0026] In this embodiment, the wire 16 electrically connects the upper and lower power connectors 15, enabling the controller 121 to supply power to the heating wire 702.

[0027] like Figure 3As shown, in some embodiments, the cleaning mechanism 13 includes a high-pressure blower 131, a hose 132, a quick connector 133, and a one-way valve 134. The high-pressure blower 131 is installed on the inner right side wall of the rectangular box 10. A hose 132 is installed on the air outlet of the high-pressure blower 131. The hose 132 is connected to the one-way valve 134 through the quick connector 133. The one-way valve 134 is fixedly installed in the upper side wall of the gun barrel 8.

[0028] In this embodiment, the high-pressure blower 131 blows air into the one-way valve 134 through the hose 132 and quick connector 133, so that the one-way valve 134 blows air into the gun barrel 8 to blow out the residual foam in the gun barrel 8, and the one-way valve 134 prevents the gas from flowing back.

[0029] In use, the expanding foam bottle is installed on the adapter 4, and the switch button 125 in the control mechanism 12 is turned on, allowing the battery 122 to supply power to the first heating mechanism 7 and the second heating mechanism 11 via the controller 121. The temperature sensor 124 monitors the temperature of the second heating mechanism 11 and feeds the information back to the controller 121, which then controls the heating temperature. The heating wire 702 in the first heating mechanism 7 heats the expanding foam bottle through the aluminum foil tape 703, thus heating the expanding foam inside the bottle. The insulation sleeve 701 reduces heat loss. Similarly, the second heating mechanism 11 heats the expanding foam inside the gun barrel 8. Pressing the wrench 3 causes the expanding foam in the foam bottle to flow into the gun barrel 8 through the control tube 2, and then be sprayed out through the nozzle 14 on the gun barrel 8. This increases the heating function of the foam gun, allowing the material to solidify after spraying, resulting in high expansion ratio, good adhesion, and resistance to peeling, which is beneficial for use in winter. After the expanding foam is filled, the switch button 125 turns on the high-pressure blower 131 in the cleaning mechanism 13. The high-pressure blower 131 blows air through the hose 132 and quick connector 133 to the one-way valve 134, causing the one-way valve 134 to blow air into the gun barrel 8, blowing out the remaining expanding foam in the gun barrel 8, thereby increasing the cleaning function of the gun barrel 8, reducing material residue in the gun barrel 8, and making the gun barrel 8 less prone to clogging.

[0030] In summary, the foaming gun for polyurethane foam materials enhances the heating function of the foaming gun through the first heating mechanism 7 and the second heating mechanism 11. This means that the single-component polyurethane foam sealant is heated so that the material can solidify after being sprayed into the seal, resulting in a high expansion ratio, good adhesion, and resistance to detachment, which is beneficial for use in winter. At the same time, it also enhances the cleaning function of the gun barrel 8, reducing material residue inside the gun barrel 8 and preventing the gun barrel 8 from becoming clogged.
