Description

Technical Field

[0001] This utility model relates to the field of expanding foam filling technology, specifically to an expanding foam filling device. Background Technology

[0002] The gaps in the exterior windows need to be filled with expanding foam; expanding foam has excellent sealing properties and can effectively fill the gaps between the window frame and the wall, preventing air, dust and insects from entering.

[0003] Existing foam filling devices are typically foam guns, which generally include a gun body, nozzle, trigger, valve, and connector. When the trigger is pressed, the foam is sprayed through the nozzle into the air, where it comes into full contact with the air and rapidly expands into foam. After spraying, the foam gradually cures, forming a strong insulating and sealing material, achieving the effects of filling gaps, heat insulation, and sound insulation.

[0004] However, the nozzle of existing foam guns is usually a straight tube that is molded in one piece. When filling gaps in window frames, the nozzle often needs to be inserted into the gap at an angle. The insertion depth is not easy to control, which may lead to overfilling or underfilling. In addition, the insertion depth of the nozzle is manually controlled, and the depth varies greatly during the filling process, which also leads to uneven filling and makes it easy for the foam to be not dense enough. Utility Model Content

[0005] The purpose of this invention is to provide a foam filling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foaming glue filling device, comprising: a foaming glue gun body, a foaming tank connecting seat provided on one side of the upper end of the foaming glue gun body, a spray pipe provided at the front end of the foaming glue gun body, a hose provided on one side of the spray pipe, one end of the hose being connected to the spray pipe through a pipe connector one, and the other end of the hose being connected to a conduit through a pipe connector two.

[0007] A nozzle is fixedly installed at the end of the conduit away from the hose. Length graduations are provided on the outer wall of the conduit, and a limit component is provided on the conduit.

[0008] Preferably, bearings are fixedly sleeved on the outer walls of both pipe connector one and pipe connector two, and round shafts are symmetrically fixedly installed on the upper and lower outer walls of the bearings.

[0009] Preferably, the upper and lower ends of the hose are provided with rotating plates, and the left and right ends of the rotating plates are respectively rotatably connected to the round shafts at the outer ends of the two bearings.

[0010] Preferably, the limiting component includes a sliding sleeve and a limiting plate. The limiting plate is annular and is fixedly installed at one end of the sliding sleeve. The inner diameter of the sliding sleeve and the inner diameter of the limiting plate are the same.

[0011] Preferably, the inner diameters of the sliding sleeve and the limiting plate are both larger than the outer diameter of the conduit, and the sliding sleeve and the limiting plate are slidably sleeved on the outer wall of the conduit.

[0012] Preferably, a threaded sleeve is fixedly installed on the outer wall of one end of the sliding sleeve, and the inner port of the threaded sleeve is connected to the inner end of the sliding sleeve.

[0013] Preferably, the threaded sleeve is internally threaded with a hand-tightening bolt, the front end of which can abut against the outer wall of the conduit.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When filling gaps in actual exterior windows, this invention can bend the hose to a certain extent according to the filling location requirements, so that there is an angle between the guide tube and the nozzle. This allows the guide tube to be inserted into the gap relatively vertically, which facilitates the control of the nozzle insertion depth, improves the filling uniformity, and makes the foam filling more compact, effectively avoiding any unfilled areas.

[0016] By observing the length scale line, the distance between the limiting plate and the nozzle can be precisely adjusted. This distance is the filling depth of the nozzle. During filling, the limiting plate is continuously blocked outside the gap. Therefore, when moving along the gap trajectory, the insertion depth of the nozzle can remain consistent, which helps to improve the filling uniformity of the foam. Attached Figure Description

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a foam glue filling device, comprising: a foam glue gun body 1, a foam can connecting seat 2 on one side of the upper end of the foam glue gun body 1, a spray pipe 3 at the front end of the foam glue gun body 1, in use, the foam glue can is installed on the foam can connecting seat 2, a hose 4 is provided on one side of the spray pipe 3, one end of the hose 4 is connected to the spray pipe 3 through a pipe connector 5, and the other end of the hose 4 is connected to a conduit 10 through a pipe connector 6, the hose 4 is installed on the spray pipe 3, and the conduit 10 is installed on the other end of the hose 4, and a nozzle 12 is fixedly installed at the end of the conduit 10 away from the hose 4. In use, the trigger of the foam glue gun body 1 is pulled, and the foam glue is sprayed out from the nozzle 12.

[0024] The outer wall of the conduit 10 is provided with a length scale line 11. When filling the actual gap of the external window, one end of the conduit 10 is inserted into the gap. By observing the length scale line 11, the insertion depth can be determined, which facilitates precise adjustment of the insertion depth and improves the filling quality.

[0025] Bearings 7 are fixedly sleeved on the outer walls of pipe connector 5 and pipe connector 6. The inner wall of the bearing 7 is fixedly connected to the outer wall of pipe connector 5 and pipe connector 6. Round shafts 8 are symmetrically fixedly installed on the upper and lower outer walls of the bearing 7. Rotating plates 9 are provided at both the upper and lower ends of the hose 4. The left and right ends of the rotating plates 9 are rotatably connected to the round shafts 8 at the outer ends of the two bearings 7 respectively. The two rotating plates 9 can rotate on the outside of the hose 4 through the bearings 7. The two rotating plates 9 can also rotate through the round shafts 8. When filling the gaps of the actual external window, the hose 4 can be bent to a certain extent according to the filling position requirements, so that there is an angle between the guide tube 10 and the nozzle 3, so that the guide tube 10 can be inserted into the gap relatively vertically, which facilitates the control of the insertion depth of the nozzle 12 and helps to improve the filling uniformity. When moving the filling, the rotating plate 9 provides support for the hose 4, moving the hose 4 and the guide tube 10 together.

[0026] The conduit 10 is provided with a limiting component, which includes a sliding sleeve 13 and a limiting plate 14. The limiting plate 14 is annular and is fixedly installed at one end of the sliding sleeve 13. The inner diameter of the sliding sleeve 13 and the inner diameter of the limiting plate 14 are the same and larger than the outer diameter of the conduit 10. The sliding sleeve 13 and the limiting plate 14 are slidably sleeved on the outer wall of the conduit 10. The position of the limiting plate 14 can be changed by sliding the sliding sleeve 13. A threaded sleeve 15 is fixedly installed on the outer wall of one end of the sliding sleeve 13. The inner port of the threaded sleeve 15 is connected to the inner end of the sliding sleeve 13. A hand-tightening bolt 16 is connected to the threaded sleeve 15. The front end of the hand-tightening bolt 16 can abut against the outer wall of the conduit 10. After the limiting plate 14 is moved to the corresponding position by observing the length scale line 11, the limiting plate 14 can be fixed by tightening the hand-tightening bolt 16.

[0027] The value on the length scale line 11 at the bottom of the limiting plate 14 is the filling depth of the nozzle 12. During filling, the limiting plate 14 is continuously blocked outside the gap. Therefore, when moving along the gap trajectory, the insertion depth of the nozzle 12 can remain consistent, which is beneficial to improving the filling uniformity of the foam.

[0028] It is important to note that the diameter of the limiting plate 14 should be greater than the width of the gap to ensure that the limiting plate 14 is limited to the outside of the gap.
