Description

Technical Field

[0001] This utility model is a glue-applying device, belonging to the technical field of extruded polystyrene board. Background Technology

[0002] In the construction of extruded polystyrene (XPS) board insulation projects, the adhesive application stage directly determines the bonding strength between the board and the base wall (or between boards), and is a core step to ensure the overall stability of the insulation layer. This process requires evenly applying adhesive to form a tightly bonded layer between the board and the contact surface. The adhesive gun, as a commonly used tool, operates according to the logic of "adhesive reservoir - gun power - adhesive discharge": Before construction, the adhesive reservoir containing adhesive is inserted into the fixed slot of the caulking gun. Pressing the handle of the caulking gun provides pressure, pushing the piston inside the reservoir forward, causing the adhesive to be discharged evenly from the outlet at the end of the reservoir, ultimately applying the adhesive to the bonding surface of the XPS board.

[0003] The single-nozzle design of existing adhesive guns presents a contradiction with the actual needs of extruded polystyrene (XPS) board installation. During insulation installation, to ensure bonding strength and sealing, at least two coats of adhesive (such as a combination of edge and internal dotted adhesive, or two parallel strips) are typically applied to the bonding surface of the XPS board. If a single-nozzle gun is used, the installer must first apply the first coat of adhesive, then adjust the gun position, and reposition it to apply the second coat to a different area of ​​the board. This repeated adjustment of the gun angle and position not only increases the number of steps but may also affect the uniformity of adhesive distribution due to inconsistent spacing between the two coats. Furthermore, the interval between coats prolongs the application time for a single board, especially in large-area construction scenarios. The efficiency bottleneck caused by the single nozzle directly slows down the overall project progress, making it difficult to meet the demands of efficient construction. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a glue application device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue-applying device, comprising: Glue gun; The glue storage cylinder is inserted into the glue gun; A straight pipe is installed at the outlet of the glue storage cylinder. Both ends of the straight pipe are open. A telescopic pipe is inserted inside the straight pipe. A bend is installed at the end of the telescopic pipe that is outside the straight pipe. A long screw is installed on the outer surface of a straight pipe. The long screw is arranged along the length of the straight pipe. Two straight threaded pipes are threaded onto the long screw. The two straight threaded pipes are closed on both sides. A short screw is installed on the back side of each of the two straight threaded pipes. The short screw is connected to a telescopic pipe.

[0006] Furthermore, a first lug is installed at the middle of the outer surface of the straight tube, and a first through hole is opened on one side of the first lug. The long screw passes through the first through hole, and a first nut is provided on both sides of the first through hole along the length of the long screw. The first nut is threadedly connected to the long screw.

[0007] Furthermore, a second lug is installed on the outer surface of the telescopic tube near the bend. A second through hole is provided on one side of the second lug, which is concentric with the first through hole. The short screw passes through the second through hole. A second nut is provided on both sides of the second through hole along the length of the short screw. The second nut is threadedly connected to the short screw.

[0008] Furthermore, a sealing sleeve is glued to the end of the telescopic tube away from the bend, and the sealing sleeve is slidably installed inside the straight tube.

[0009] Furthermore, a pipe fitting is installed at the middle of the outer surface of the straight pipe, and the end of the pipe fitting away from the straight pipe is threadedly connected to the outlet of the glue storage cylinder.

[0010] Furthermore, an internally threaded sleeve is installed at the end of the bend away from the telescopic tube, and the internally threaded sleeve is internally connected to the discharge tube.

[0011] Furthermore, one end of the discharge pipe is machined with an external thread, and the end of the discharge pipe with the external thread is threadedly connected to the internal thread sleeve. The end of the discharge pipe away from the external thread is machined with a bevel.

[0012] Furthermore, the end of the straight threaded pipe away from the bend is machined with four flat surfaces arranged in a ring at equal intervals for engaging the wrench, and the telescopic pipe and the bend are integrally formed.

[0013] The beneficial effects of this utility model are: The adhesive from the storage cylinder first enters the straight pipe, then flows to the telescopic pipes at both ends of the straight pipe, and is discharged synchronously through the bend pipe and the discharge pipe, forming two independent discharge ports. During construction, there is no need to repeatedly adjust the position of the caulking gun. Two coats of adhesive can be applied to the bonding surface of the extruded polystyrene board in one operation, eliminating the repetitive steps of "applying one coat of adhesive - adjusting the position - applying the second coat of adhesive" in traditional equipment. The adhesive application time for a single board is shortened, making it especially suitable for large-area construction scenarios and effectively breaking through the efficiency bottleneck.

[0014] The two straight threaded tubes on the long screw can move along the long screw, driving the short screw and the telescopic tube to move synchronously, thereby adjusting the distance between the two discharge tubes. For wide plates, the distance can be increased, and for narrow plates, the distance can be decreased to ensure that the adhesive distribution meets the construction specifications. At the same time, the telescopic tube can slide and adjust its extension length inside the straight tube. Combined with the angle design of the bend tube, it can flexibly adapt to different adhesive application areas such as the edge and middle of the plate. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a glue application device, including a glue gun 1, a glue storage cylinder 2 inserted into the glue gun 1; a pipe connector 31 is installed at the middle position of the outer surface of a straight tube 3, so that the end of the pipe connector 31 away from the straight tube 3 is threadedly connected to the outlet of the glue storage cylinder 2, thus completing the installation of the straight tube 3 at the outlet of the glue storage cylinder 2. The structure and working principle of the glue gun 1 have been fully disclosed in the prior art, so they will not be described in detail here.

[0018] See Figures 1-4Both ends of the straight pipe 3 are open. A telescopic pipe 32 is inserted inside the straight pipe 3. A bend 33 is installed at the end of the telescopic pipe 32 outside the straight pipe 3. The telescopic pipe 32 and the bend 33 are integrally formed. An internally threaded sleeve 34 is installed at the end of the bend 33 away from the telescopic pipe 32. One end of the discharge pipe 4 is machined with an external thread, so that the threaded end of the discharge pipe 4 is threaded into the internally threaded sleeve 34, completing the assembly of the discharge pipe 4 and the bend 33. When the discharge pipe 4 is worn due to contact with the wall, it is easy to replace the worn discharge pipe 4 separately. A bevel is machined at the end of the discharge pipe 4 away from the external thread to facilitate the adhesion of adhesive to the wall or extruded polystyrene board.

[0019] See Figures 1-4 A first lug 52 is installed at the middle of the outer surface of the straight pipe 3. A first through hole is opened on one side of the first lug 52, through which a long screw 5 passes. A first nut 53 is provided on both sides of the first through hole along the length of the long screw 5. The first nut 53 is threadedly connected to the long screw 5. The first nut 53 and the first lug 52 cooperate with each other to install the long screw 5 on the outer surface of the straight pipe 3. The long screw 5 is arranged along the length of the straight pipe 3. Two straight threaded pipes 51 are threadedly connected to the long screw 5, with the two straight threaded pipes 51 facing each other. Both are closed structures. Short screws 55 are installed on the opposite sides of the two straight threaded tubes 51. A second lug 57 is installed on the outer surface of the telescopic tube 32 near the bend 33. One side of the second lug 57 has a second through hole arranged concentrically with the first through hole. The short screw 55 passes through the second through hole. Second nuts 56 are provided on both sides of the second through hole along the length of the short screw 55. The second nuts 56 are threadedly connected to the short screw 55, and the two nuts cooperate to complete the connection between the short screw 55 and the telescopic tube 32. The two straight threaded tubes 51 on the long screw 5 can move along the long screw 5, causing the short screw 55 and the telescopic tube 32 to move synchronously, thereby adjusting the distance between the two discharge tubes 4. The distance can be increased for wide plates and decreased for narrow plates to ensure that the adhesive distribution meets construction specifications. Simultaneously, the telescopic tube 32 can slide within the straight tube 3 to adjust its extension length. Combined with the angle design of the bend 33, it can flexibly adapt to different adhesive application areas such as the edge and center of the plate.

[0020] The end of the telescopic tube 32 away from the bend 33 is glued with a sealing sleeve 35, which slides inside the straight tube 3. The end of the straight threaded tube 51 away from the bend 33 has four flat surfaces 54 arranged in a ring at equal intervals for engaging wrenches. The sealing sleeve 35 is glued to the end of the telescopic tube 32 away from the bend 33. When the sealing sleeve 35 slides inside the straight tube 3, it can fit tightly against the tube wall to prevent the glue from leaking from the gap between the telescopic tube 32 and the straight tube 3. The glue in the glue storage cylinder 2 first enters the straight tube 3, and then flows to the telescopic tubes 32 at both ends of the straight tube 3. It is discharged synchronously through the bend 33 and the discharge pipe 4, forming two independent discharge ports. During construction, there is no need to repeatedly adjust the position of the glue gun 1. Two coats of glue can be applied to the bonding surface of the extruded polystyrene board in one operation, eliminating the repetitive steps of "applying one coat of glue - adjusting the position - applying the second coat of glue" in traditional equipment. The glue application time for a single board is shortened, which is especially suitable for large-area construction scenarios and effectively breaks through the efficiency bottleneck.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
