Description

Technical Field

[0001] This utility model belongs to the field of door and window installation technology, and in particular relates to a sealing machine for door and window installation. Background Technology

[0002] Doors and windows are categorized as either enclosure components or partition components based on their location, and each has different design requirements, including functions such as heat insulation, sound insulation, waterproofing, and fire resistance. New requirements emphasize energy conservation; in cold regions, heat loss due to gaps in doors and windows accounts for approximately 25% of total heating consumption. Therefore, the airtightness of doors and windows is a crucial aspect of energy-saving design. Doors and windows are essential components of the building envelope system. Various adhesives are used during the installation of doors and windows to achieve functions such as sealing and sound insulation.

[0003] For example, patent application number CN202420640956.7 discloses a sealing machine for door and window installation, including a control ring and a connecting piece. The control ring has a locking groove inside, and a locking gear is fixedly connected inside the locking groove. A locking toothed ring is fixedly connected to the side of the connecting piece facing the control ring. The locking toothed ring is slidably connected inside the locking groove and meshes with the locking gear. The control ring has an inner discharge hole inside, and the connecting piece has an outer discharge hole inside. A discharge pipe is fixedly connected to the side of the connecting piece away from the control ring. This design can control the discharge amount of the sealing machine according to the gap between the door and window, preventing unnecessary sealing of one door or window gap and thus avoiding wasted manpower in subsequent processing.

[0004] Existing technology, through the control ring and discharge port, can control the output of the sealing machine according to the gap between doors and windows, but there are still some shortcomings in its overall use: Firstly, the existing method of applying sealant involves using a sealant gun and a silicone sealant cartridge to seal the gaps. However, after the sealant is applied to the gaps, workers have to smooth the sealant with a trowel or other tools, which is a cumbersome process and greatly reduces the efficiency of applying sealant. Secondly, when sealing doors and windows, a clean and dust-free surface is required. If there is dust or other impurities in the gap between the doors / windows and the wall, these impurities will form an isolation layer, causing the sealant to be unable to adhere tightly to the substrate, thereby reducing the bonding strength and making it easy to crack, fall off, or even cause water seepage in severe cases. Finally, when applying the sealant, it is necessary to manually hold the sealant gun to maintain the distance between the nozzle and the window frame. However, the manual operation cannot completely control the distance between the nozzle and the sealant application point. The size of the distance can easily lead to the application of too much or too little sealant, resulting in unstable sealant application. Furthermore, the nozzle pressing against the window frame can easily cause scratches on the window frame. Utility Model Content

[0005] This invention addresses the problems of existing technologies, such as the need for secondary trimming with a trowel after applying the sealant, which is cumbersome and affects overall efficiency. Furthermore, dust, oil, and other impurities on the substrate surface can form an isolation layer, causing the sealant to crack, peel off, or even leak. Additionally, relying on manual feel makes it difficult to maintain a constant dispensing distance and angle, resulting in uneven sealant application, and the nozzle can easily scratch the window frame. Therefore, this invention provides a sealant machine for door and window installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing machine for door and window installation, comprising a glue applicator tube, a pusher plate slidably installed inside the glue applicator tube, a conical collection chamber fixedly installed at one end of the glue applicator tube, a threaded tube threadedly installed at one end of the collection chamber, a detachable glue outlet tube threadedly installed at one end of the threaded tube, a glue outlet head connected to one end of the glue outlet tube, an air pump fixedly installed on the upper surface of the glue applicator tube, a conduit connected to the air outlet end of the air pump, the conduit connecting to the collection chamber, which, when inflated, can blow air to remove dust from the glue application area and simultaneously remove residual glue from the glue outlet head, and a scraper head slidably installed on one side of the glue outlet tube above the glue outlet head.

[0007] Optionally, a fixing rod is fixedly installed on one side of the dispensing tube above the dispensing head. A first spring is fixedly installed inside the fixing rod. A telescopic rod that slides inside the fixing rod is fixedly installed at the top of the first spring. The end of the telescopic rod away from the first spring is fixed to the scraper head.

[0008] Optionally, the lower surface of the scraper head is a slope.

[0009] Optionally, a threaded rod is rotatably installed inside the glue applicator tube, and a threaded sleeve is threadedly fitted on the outer surface of the threaded rod. One end of the threaded sleeve is fixed to the pusher plate.

[0010] Optionally, slide rods are slidably installed on both sides of the glue dispensing tube, and two mounting plates are fixedly installed on one end of the two slide rods near the glue dispensing tube. A rubber roller is rotatably installed between the two mounting plates.

[0011] Optionally, movable rods are slidably installed on both sides of the glue applicator tube, and the slide rod is slidably fitted inside one end of the movable rod. Both the end of the movable rod and the end of the slide rod are fixedly installed with washers. A second spring sleeved on the outside of the slide rod is fixedly installed between the two washers, and the mounting plate is fixedly installed on the surface of the washers on the slide rod.

[0012] Optionally, fixing blocks are fixedly installed on both sides of the glue applicator, the movable rod slides inside the fixing blocks, and the outer side of the fixing blocks is threaded with a threaded knob that abuts against the movable rod.

[0013] Optionally, a handle is fixedly installed at the bottom of the glue applicator, a battery is fixedly installed at the bottom of the handle, and a switch is provided on the side of the handle near the glue outlet.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This utility model, through the setting of collection bin, threaded pipe, glue outlet pipe, glue outlet head, guide tube and scraper, can blow away dust in the gap between the door / window and the wall before sealing the door / window, so that the sealant can adhere tightly to the substrate and improve the sealing effect. At the same time, it can smooth it after sealing, saving subsequent processing time and improving work efficiency. It can also clean the glue outlet head after sealing to avoid blockage caused by long-term disuse.

[0015] (2) By setting up a fixed block, a moving rod, a sliding rod, a second spring, a mounting plate and a rubber roller, this utility model can accurately control the distance between the glue gun head and the window frame without relying on manual hand force when sealing glue, thus preventing the glue amount from being too large or too small and greatly improving the stability of glue application.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] refer to Figure 1 A sealing machine for door and window installation includes a glue applicator 10, a handle 11 fixedly installed at the bottom of the glue applicator 10, a storage battery 12 installed at the bottom height of the handle 11, and a switch 13 opened on one side of the handle 11. During operation, the storage battery 12 is used to power the equipment. The operator holds the handle 11 and applies glue to the door and window through the glue applicator 10. The switch 13 can control the glue dispensing amount of the glue applicator 10.

[0020] Further reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A collection chamber 18 is fixedly installed on one side of the glue applicator 10. A threaded tube 19 is fixedly installed at one end of the collection chamber 18, and a glue dispensing tube 20 is threaded onto one end of the threaded tube 19. A glue dispensing head 21 is connected to one side of the glue dispensing tube 20. In use, the glue dispensing tube 20 can be removed, the glue applicator opened, and inserted into the glue applicator 10. During glue application, the glue can be discharged from the glue dispensing head 21 for sealing doors and windows. After the glue is used up, the glue bag is compressed inside the collection chamber 18 and the threaded tube 19, ensuring that the glue in the bag can be completely squeezed out of the glue applicator 10. To save on subsequent cleaning hassles, the glue dispensing tube 20 can be removed and a new glue bag replaced when changing the glue bag.

[0021] Further reference Figure 3 and Figure 6 The glue dispensing tube 10 has a threaded rod 15 rotatably mounted inside. A motor 14 that drives the threaded rod 15 is fixedly mounted on the side of the glue dispensing tube 10 near the handle 11. A threaded sleeve 16 is threadedly fitted on the outer surface of the threaded rod 15. A pusher plate 17 is fixedly mounted on the end of the threaded sleeve 16 away from the threaded rod 15. In use, the output end of the motor 14 drives the threaded rod 15 to rotate. Since the threaded sleeve 16 is threadedly fitted with the threaded rod 15, the threaded sleeve 16 moves forward while the threaded rod 15 rotates. Then, the pusher plate 17 squeezes the glue tube, squeezing the glue out of the glue outlet 21. In this operation, the glue dispensing amount can be precisely controlled by the rotation speed of the motor 14 and the engagement of the threaded rod 15, improving the usage effect.

[0022] Further reference Figure 1 and Figure 3An air pump 22 is fixedly installed at the top of the glue application tube 10. A conduit 23 is fixedly installed at the air outlet of the air pump 22, and the conduit 23 is connected to the collection chamber 18. A one-way valve (not shown in the figure) is provided at the connection between the conduit 23 and the collection chamber 18. Before applying the glue, air can be pumped into the collection chamber 18 through the air pump 22 and the conduit 23, and then discharged through the glue application tube 20. This blows out the dust from the sealant application, facilitating a tight bond between the sealant and the substrate and improving the sealing effect. After sealing, air can be continued to be pumped in to discharge any remaining glue inside the glue application tube 20, preventing blockage of the tube 20 if it is not used for a long time.

[0023] Further reference Figure 1 and Figure 4 A fixing rod 24 is fixedly installed on one side of the glue dispensing tube 20 above the glue dispensing head 21. A first spring 25 is fixedly installed inside the fixing rod 24. A telescopic rod 26 that slides inside the fixing rod 24 is fixedly installed at the end of the first spring 25. A scraper head 27 is fixedly installed at the outer end of the telescopic rod 26. The lower surface of the scraper head 27 is inclined. When applying glue, the scraper head 27 can smooth the glue, reduce the time for subsequent processing, and improve tooling efficiency. The use of the first spring 25 can ensure that the scraper head 27 fits the glue joint and improves the use effect.

[0024] Further reference Figure 1 and Figure 5 Fixing blocks 28 are fixedly installed on both sides of the glue applicator 10. A moving rod 29 is slidably installed inside the fixing block 28. A threaded knob 30 for limiting the moving rod 29 is threadedly fitted on the outside of the fixing block 28. A sliding rod 31 is slidably installed at the end of the moving rod 29 away from the threaded knob 30. A washer 33 is fixedly installed at the end of the moving rod 29 and the end of the sliding rod 31. The washer 33 is made of damping material (such as rubber). A second spring 32 is fixedly installed between the two washer 33 and sleeved on the outside of the sliding rod 31. Two mounting plates 34 are fixedly installed on the surface of the washer 33. A rubber washer is fixedly installed between the two mounting plates 34. When in use, the roller 35 allows the moving rod 29 to slide inside the fixed block 28, adjusting the distance between the moving rod 29 and the door / window for easier support and fixation during subsequent caulking. After adjustment, the threaded knob 30 can be tightened to limit the movement of the moving rod 29. Simultaneously, the rubber roller 35 abuts against both sides of the gap. The second spring 32 provides cushioning and shock absorption during caulking support, preventing vibration that could lead to discontinuous caulking and reduced caulking quality. The rubber roller 35 further enhances the shock absorption effect, improves the stability during caulking, and prevents the glue tube 20 from damaging the window frame.

[0025] Finally, it should be noted that the sealing machine for door and window installation of this utility model can be connected and fixed by conventional mechanical connection structures. The control system and connection method required between multiple electrical components and drive components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as the beneficial effect or the specific actions in the above work can be achieved, it can be implemented.
