Description

Technical Field

[0001] The invention relates to the technical field of building hole plugging, in particular to a foam glue spraying device for building hole plugging. Background Art

[0002] After the main body of a building is completed, there are many holes that need to be sealed, such as construction holes, scaffolding holes and formwork holes, heating pipe holes, kitchen and toilet holes, etc. If the sealing is not done seriously and the sense of responsibility is not strong, cracks will be caused at the edges of the holes, and even leakage will occur. The existing sealing method is to insert a glue gun equipped with foam glue into the holes and inject foam glue into the holes to seal them.

[0003] The Chinese invention patent document (publication number: CN116181111B) discloses a foam glue spraying device for plugging holes in buildings, which belongs to the field of building construction technology. The technical problem to be solved is that the existing foam glue cannot completely fill the holes and affects the plugging effect. The adopted scheme is: the foam glue spraying device for plugging holes in buildings includes a foam glue spraying glue gun and a glue outlet pipe. When the foam glue spraying device for plugging holes in buildings provided by the present invention is used, the foam glue spraying glue gun is used to spray the foam glue inside the hole, slowing down the speed at which the glue outlet pipe slides out of the hole, so as to achieve the foam glue perfect filling of the hole. At this time, the foam glue will extrude the extrusion ring, increase the density of the foam glue inside the hole, and improve the plugging effect. At the same time, the arc rotating plate and the positioning ring are controlled to always fit the wall surface, ensuring that the glue outlet pipe of the foam glue spraying glue gun is always in the center of the hole when in use, and at the same time improving the plugging effect of the extrusion ring on the hole. The foam glue spraying device is applied to the field of plugging holes in buildings.

[0004] However, in the above patent, when the foaming spray gun is used, the foaming glue cartridge is fixed on the foaming spray gun and used directly, which reduces the activity and foaming effect of the foaming glue.

[0054] In this embodiment, the clamping mechanism is arranged on the clamping seat 32 and is used to clamp and fix the foam rubber tube. The clamping mechanism includes a rotating rod 34 rotatably connected to the clamping seat 32, and the rotating rod 34 is fixedly connected to the output shaft of the clamping motor 10. One end of the rotating rod 34 is fixedly connected to a first bevel gear 35. A clamping screw 36 is rotatably connected in the clamping seat 32, and a second bevel gear 37 is fixedly connected to the clamping screw 36. The second bevel gear 37 is meshed with the first bevel gear 35. Both ends of the clamping screw 36 are threadedly connected to a screw sleeve 38, and both screw sleeves 38 are screwed. A movable plate 39 is fixedly connected, and the two movable plates 39 are slidably connected to the clamping seat 32. The sliding between the two movable plates 39 and the clamping seat 32 makes the two screw sleeves 38 move horizontally. Push rods 40 are fixedly connected to the opposite sides of the two movable plates 39, and the two push rods 40 are slidably connected to the clamping seat 32. One end of the two push rods 40 is fixedly connected to a clamping plate 41, and the two clamping plates 41 are located in the second notch 33. The two movable plates 39 drive the two clamping plates 41 to approach each other through the two fixedly connected push rods 40 to fix and clamp the foam rubber tube.

[0055] In this embodiment, a connecting head 43 is provided at the bottom of the placement tube 7, a plurality of protruding plates 44 are fixedly installed on the outer ring of the mounting plate 6, a plurality of mounting screws 45 are provided between the plurality of protruding plates 44 and the support plate 5, one end of the injection tube 3 is fixedly connected to a gun plate 46, and an injection head 47 is provided on the gun plate 46, and the support plate 5 and the mounting plate 6 can be fixedly installed by a plurality of mounting screws 45.

[0056] In this embodiment, two top plates 54 are symmetrically fixedly installed at the bottom of the placement tube 7, and electric push rods 55 are fixedly installed at the bottom of the two top plates 54. The two electric push rods 55 are fixedly connected to the fixed plate 9. The two electric push rods 55 are used to drive the fixed plate 9 to move downward and drive the two internal blocks 8 to slide in the placement tube 7. A limit rod 56 is fixedly provided on the fixed plate 9. The limit rod 56 is slidably connected to the heating plate 18 and the clamping seat 32. The limit rod 56 can limit the heating plate 18 and the clamping seat 32. A toggle handle 53 is provided on the foam glue gun body 1.

[0057] The implementation principle of the foam glue spraying device for plugging holes in buildings in the embodiment of the present application is as follows: first, the placement tube 7 fixedly connected to the mounting plate 6 is placed on the support plate 5, and is fixedly installed by a plurality of mounting screws 45. At the same time, the foam glue tube is placed in the placement tube 7 and passes through the first notch 19, the second notch 33 and the third notch 42. The heating switch 21 is turned on to allow the heating wire 20 to start preheating, and the clamping motor 10 is started so that the output shaft of the clamping motor 10 drives the rotating rod 34 to rotate. The rotating rod 34 utilizes the meshing between the first bevel gear 35 and the second bevel gear 37 to drive the clamping screw 36 to rotate. Since the thread directions at both ends of the clamping screw 36 are respectively aligned with the thread directions of the two screw sleeves 38, The two movable plates 39 are slidably connected to the clamping seat 32, so that when the clamping screw 36 rotates, the two screw sleeves 38 can be driven to approach each other, and the two screw sleeves 38 drive the two movable plates 39 to approach each other. The two movable plates 39 drive the two clamping plates 41 to approach each other through the two push rods 40 that are fixedly connected to fix the foaming rubber tube. The drive motor 12 is started so that the output shaft of the drive motor 12 drives the drive rod 14 to rotate. The drive rod 14 uses the meshing between the first bevel gear 24 and the second bevel gear 26 to drive the transmission rod 25 to rotate. The transmission rod 25 drives the cam 27 to rotate and reciprocate to squeeze the horizontal plate 31 to move downward. The horizontal plate 31 is driven by the fixedly connected vertical plate 30 The pressure plate 29 moves downward and compresses the shaking spring 28. When the shaking spring 28 releases its elastic force, it can drive the pressure plate 29 to reset upward. The pressure plate 29 drives the horizontal plate 31 to reset upward through the fixedly connected vertical plate 30 to achieve the effect of reciprocating movement. The horizontal plate 31 drives the clamping seat 32 to move back and forth, and then drives the clamped foaming rubber tube to move back and forth to shake it, so as to achieve the effect of uniform mixing of the foaming agent. Since the activity of the foaming agent is usually related to its temperature, the higher the temperature, the higher the activity of the foaming agent, and the better the foaming effect, the driving rod 14 drives the reciprocating screw rod 15 to rotate, and utilizes the sliding limit between the limit plate 17 and the limit hole 13 to make the pin barrel 16 follow the reciprocating groove of the reciprocating screw rod 15. The pin cylinder 16 moves downward, and the heating plate 18 moves back and forth through the fixed limit plate 17, so that the heating wire 20 in the first notch 19 evenly heats the foaming rubber tube, thereby improving the activity and foaming effect of the foaming agent. When the hole needs to be sealed, the two electric push rods 55 are used to drive the fixed plate 9 to move downward, and drive the two internal blocks 8 to slide in the placement tube 7, and the clamping mechanism on the clamping seat 32 is used to drive the foaming rubber tube to contact and squeeze with the connecting head 43, and then the injection head 47 is located in the hole. By toggling the toggle handle 53, the foaming agent in the foaming rubber tube can enter the delivery pipe 4 through the connecting head 43, and then enter the injection pipe 3 and the injection head 47 in turn to spray and seal the hole.
