Description

Technical Field

[0001] This utility model relates to the field of door and window installation technology, and more specifically, to a glue injection device for installing door and window glass. Background Technology

[0002] Doors and windows are building units and decorative symbols of facade effects, ultimately reflecting the characteristics of the building. Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions and sashes. Aluminum alloy doors and windows not only have high hardness and light overall weight, but also have a beautiful metallic luster, so they are widely loved by people.

[0003] When installing existing aluminum alloy doors and windows, they need to be used with glass. The glass and aluminum alloy doors and windows are fixed together with glue. The existing glue application method is generally manual. Manual glue application is inconvenient to control the distance between the glue nozzle and the bottom of the glue groove. In addition, it is labor-intensive and cannot accurately control the glue application speed, which leads to problems such as glue splashing or unevenness.

[0004] A search revealed that Chinese patent CN111515088A discloses a glue-applying device for glass installation in aluminum alloy doors and windows. The device allows adjustment of the glue nozzle position via adjusting bolts. A glue-applying frame drives a sponge to press the glass against the door / window. A detection rod, along with variable resistors and coils, enables adaptive adjustment of the glue-applying speed, reducing glue splashing and ensuring smooth application. Furthermore, the deformation of the sponge under pressure drives related components, connecting segmented resistors in series. The width of the glue-applying groove can be indirectly determined based on the sponge's resistance. Two sets of variable resistors control the liquid pump output, automatically adjusting the glue application amount and enhancing the connection between the glass and the door / window. Additionally, the roller design at the bottom of the work frame replaces manual glue application, reducing worker fatigue. The abrasion-resistant layer on the outer surface of the sponge reduces wear, and rolling bearings between the support rod and the soft magnetic cylinder ensure connection stability, improving the device's lifespan and performance.

[0005] However, in actual use, this structure cannot stir the colloid. If the colloid is left to stand for a long time, its properties may change, and the colloid may precipitate, clump, etc., affecting the uniformity and flowability of the colloid, and thus affecting the quality of the colloid injection. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a glue injection device for installing door and window glass to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A glue injection device for installing door and window glass includes a support frame, a main glue cylinder is fixedly installed inside the support frame, an inlet pipe is provided through the top of the main glue cylinder, a sealing cap is threaded to the top of the inlet pipe, and a stirring mechanism is provided inside the support frame.

[0009] The stirring mechanism includes a small motor fixedly mounted on the top of a support frame. A rotating shaft is fixedly mounted on the output end of the small motor. A support frame is fixedly mounted on the output end of the rotating shaft. A scraper is fixedly mounted on the surface of the support frame.

A U-shaped conveying pipe is provided through one end of the main glue cylinder. An auxiliary glue cylinder is provided through one end of the U-shaped conveying pipe.

[0010] By adopting the above technical solution, the adhesive solution is uniformly stirred in all directions. Moreover, the design of the sealing cap and feed pipe prevents the adhesive solution from leaking and impurities from entering. The overall structure is compact and reasonable. The multi-stage coordination from stirring, storage to transportation effectively improves the efficiency and quality of adhesive injection and reduces the difficulty of construction operations.

[0011] As a further description of the above technical solution: a glue supply mechanism is provided on one side of the auxiliary glue cylinder, the glue supply mechanism includes a discharge hopper fixedly installed at the bottom of the auxiliary glue cylinder, a glue outlet is threadedly connected to the bottom of the discharge hopper, multiple flow control valves are provided on the surface of the U-shaped conveying pipe and the discharge hopper, and a piston is slidably installed inside the auxiliary glue cylinder;

[0012] A limit rod is fixedly installed on the inner wall of the auxiliary rubber cylinder, and the limit rod is slidably connected to the piston. A bidirectional air pump is fixedly installed on one side of the auxiliary rubber cylinder.

[0013] By adopting the above technical solution: a bidirectional air pump linked piston, the extrusion and delivery of the colloid are precisely controlled by air inflation and air extraction. Combined with a flow control valve, the dispensing speed and flow rate can be flexibly adjusted to adapt to different installation scenarios. Moreover, the hopper and dispensing nozzle are threadedly connected, which is convenient for disassembly and replacement, and meets diverse dispensing needs.

[0014] As a further description of the above technical solution: the surface of the support frame is threaded with multiple threaded support legs, and a handle is fixedly provided on the top of each threaded support leg;

The surfaces of the main rubber tube and the auxiliary rubber tube are both provided with observation grooves, and tempered glass is fixedly mounted inside the observation grooves. A hand handle is fixedly mounted on one side of the support frame.

[0016] By adopting the above technical solution, the height of the device can be flexibly adjusted to adapt to different construction surfaces. Moreover, the tempered glass in the observation tank allows operators to clearly see the amount of glue in the glue cylinder in real time and replenish it in time to avoid interrupting the operation.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up a stirring mechanism, the unique bidirectional stirring design, compared with existing technologies, combines vertical and horizontal stirring rods working together. With the help of a scraper to remove the adhesive adhering to the cylinder wall, the adhesive can be stirred quickly, efficiently and evenly, effectively avoiding sedimentation and clumping, ensuring the quality of the adhesive application.

[0019] 2. By setting up a glue supply mechanism, compared with existing technologies, it adopts gravity, stirring pressure and negative pressure to supply glue in a coordinated manner. The U-shaped delivery pipe and bidirectional air pump can quickly and efficiently deliver the glue in the main glue cylinder to the auxiliary glue cylinder, ensuring the continuity of glue supply. In addition, the bidirectional air pump combined with the piston design can achieve precise glue injection by air compression. With the adjustable flow control valve, the glue dispensing speed and flow can be flexibly controlled according to different scenarios, adapting to various door and window glass installation needs. Furthermore, the setting of the observation slot and tempered glass makes it easy to check the glue balance in real time, avoiding the interruption of work due to insufficient glue. The hand handle enhances the stability of operation, makes the device flexible to move, improves glue injection efficiency and construction quality. The overall structure is compact and practical, effectively reducing the difficulty of manual operation and construction costs, and has high engineering application value.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] The embodiments disclosed in this application are as follows: Figures 1-5 The device shown is a glue injection device for installing door and window glass, including a support frame 1, a main glue cylinder 2 is fixedly installed inside the support frame 1, an inlet pipe 3 is provided through the top of the main glue cylinder 2, a sealing cap 4 is threadedly connected to the top of the inlet pipe 3, and a stirring mechanism is provided inside the support frame 1.

[0028] The stirring mechanism includes a small motor 5 fixedly mounted on the top of the support frame 1. A rotating shaft 6 is fixedly mounted on the output end of the small motor 5. A support frame 7 is fixedly mounted on the output end of the rotating shaft 6. A scraper 8 is fixedly mounted on the surface of the support frame 7. Multiple horizontal stirring rods 9 are fixedly mounted on the surface of the rotating shaft 6. Multiple vertical stirring rods 10 are fixedly mounted on the surface of the scraper 8. A U-shaped conveying pipe 11 is provided through one end of the main glue cylinder 2. An auxiliary glue cylinder 12 is provided through one end of the U-shaped conveying pipe 11.

[0029] Open the sealing cap 4 at the top of the feed pipe 3 and pour the adhesive into the main glue cylinder 2 through the feed pipe 3. After adding, tighten the sealing cap 4 to prevent the adhesive from leaking and impurities from entering. Then connect the small motor 5 to the external power supply and turn on the small motor 5 fixed on the top of the support frame 1. The small motor 5 drives the rotating shaft 6 to rotate.

[0030] When the rotating shaft 6 rotates, the multiple horizontal stirring rods 9 fixed on its surface rotate accordingly, vertically stirring the adhesive liquid in the main glue cylinder 2. At the same time, the support frame 7 connected to the rotating shaft 6 also rotates synchronously. The scraper 8 fixed on the surface of the support frame 7 moves against the inner wall of the main glue cylinder 2 during rotation to prevent the adhesive liquid from adhering to the cylinder wall. In addition, the multiple vertical stirring rods 10 on the surface of the scraper 8 horizontally stir the adhesive liquid. Through the synergistic action of the horizontal and vertical stirring rods, the adhesive liquid is fully mixed and uniform.

[0031] While stirring, the flow control valve 15 on the U-shaped delivery pipe 11 is opened, and the uniformly stirred colloid in the main glue cylinder 2 enters the auxiliary glue cylinder 12 through the U-shaped delivery pipe 11 under the action of gravity and the pressure generated by stirring.

[0032] Reference Figures 2-4 As shown, a glue supply mechanism is provided on one side of the auxiliary glue cylinder 12. The glue supply mechanism includes a discharge hopper 13 fixedly installed at the bottom of the auxiliary glue cylinder 12. A glue outlet 14 is threadedly connected to the bottom of the discharge hopper 13. Multiple flow control valves 15 are provided on the surface of the U-shaped conveying pipe 11 and the discharge hopper 13. A piston 16 is slidably installed inside the auxiliary glue cylinder 12.

[0033] A limiting rod 17 is fixedly installed on the inner wall of the auxiliary rubber cylinder 12. The limiting rod 17 is slidably connected to the piston 16. A bidirectional air pump 18 is fixedly installed on one side of the auxiliary rubber cylinder 12.

[0034] At the same time, connect the air pump 18 to an external power source and start the bidirectional air pump 18. The bidirectional air pump 18 draws air into the auxiliary glue cylinder 12, thereby driving the piston 16 to slide inside the auxiliary glue cylinder 12 to form a negative pressure, which in turn drives the evenly stirred glue to enter the auxiliary glue cylinder 12.

[0035] Then, when performing the glue injection operation, close the flow control valve 15 set on the U-shaped conveying pipe 11, open the flow control valve 15 on the discharge hopper 13, and restart the bidirectional air pump 18. The bidirectional air pump 18 inflates the auxiliary glue cylinder 12, driving the piston 16 to move downward in the auxiliary glue cylinder 12, thereby squeezing the glue and extruding it through the discharge hopper 13 from the glue nozzle 14. The operator can hold the hand handle 25 fixed on one side of the support frame 1 to easily control the movement direction and stability of the device for glue injection operations on door and window glass.

[0036] Reference Figure 1 , 5 As shown, the support frame 1 has multiple threaded support legs 19 connected to its surface by threads, and a handle 20 is fixedly provided on the top of each threaded support leg 19;

[0037] The bottom of the threaded support leg 19 is rotatably provided with a chassis 21, and the bottom of the chassis 21 is fixedly provided with a roller 22. The surfaces of the main rubber tube 2 and the auxiliary rubber tube 12 are both provided with observation grooves 23, and tempered glass 24 is fixedly provided inside the observation grooves 23. A hand handle 25 is fixedly provided on one side of the support frame 1.

[0038] Operators can control the extrusion flow and speed of the adhesive by adjusting the flow control valve 15 on the discharge hopper 13 according to the actual adhesive injection needs. After the adhesive injection is completed, the bidirectional air pump 18 and all flow control valves 15 are turned off to stop the delivery and extrusion of the adhesive.

[0039] Operators can observe the remaining amount of adhesive in the glue tubes at any time through the observation slots 23 on the surface of the main glue tube 2 and the auxiliary glue tube 12, and through the tempered glass 24 fixed inside, so as to replenish the adhesive in a timely manner.

[0040] Working principle of this utility model:

[0041] This utility model is a glue injection device for installing door and window glass. When using the device, move the device to the vicinity of the door and window glass installation position, use the rollers 22 at the bottom of the chassis 21 to move the device to the appropriate position, and then adjust the height of the threaded support leg 19 by rotating the handle 20 on the threaded support leg 19, thereby driving the glue outlet 14 at the bottom of the main glue cylinder 2 and the auxiliary glue cylinder 12 to the appropriate position.

[0042] Then open the sealing cap 4 at the top of the feed pipe 3 and pour the glue into the main glue cylinder 2 through the feed pipe 3. After adding, tighten the sealing cap 4 to prevent glue leakage and impurities from entering. Then connect the small motor 5 to the external power supply and turn on the small motor 5 fixed on the top of the support frame 1. The small motor 5 drives the rotating shaft 6 to rotate.

[0043] When the rotating shaft 6 rotates, the multiple horizontal stirring rods 9 fixed on its surface rotate accordingly, vertically stirring the adhesive liquid in the main glue cylinder 2. At the same time, the support frame 7 connected to the rotating shaft 6 also rotates synchronously. The scraper 8 fixed on the surface of the support frame 7 moves against the inner wall of the main glue cylinder 2 during rotation to prevent the adhesive liquid from adhering to the cylinder wall. In addition, the multiple vertical stirring rods 10 on the surface of the scraper 8 horizontally stir the adhesive liquid. Through the synergistic action of the horizontal and vertical stirring rods, the adhesive liquid is fully mixed and uniform.

[0044] While stirring, the flow control valve 15 on the U-shaped conveying pipe 11 is opened. The colloid that is stirred evenly in the main glue cylinder 2 enters the auxiliary glue cylinder 12 through the U-shaped conveying pipe 11 under the action of gravity and the pressure generated by stirring.

[0045] At the same time, connect the air pump 18 to an external power source and start the bidirectional air pump 18. The bidirectional air pump 18 draws air into the auxiliary glue cylinder 12, thereby driving the piston 16 to slide inside the auxiliary glue cylinder 12 to form a negative pressure, which in turn drives the evenly stirred glue to enter the auxiliary glue cylinder 12.

[0046] Then, when performing the glue injection operation, close the flow control valve 15 set on the U-shaped conveying pipe 11, open the flow control valve 15 on the discharge hopper 13, and start the bidirectional air pump 18 again. The bidirectional air pump 18 inflates the auxiliary glue cylinder 12, driving the piston 16 to move downward in the auxiliary glue cylinder 12, thereby squeezing the glue and squeezing the glue through the discharge hopper 13 and out of the glue nozzle 14. The operator can hold the hand handle 25 fixed on one side of the support frame 1 to easily control the movement direction and stability of the device and perform the glue injection operation on the door and window glass.

[0047] Operators can control the extrusion flow and speed of the adhesive by adjusting the flow control valve 15 on the discharge hopper 13 according to the actual adhesive injection needs. After the adhesive injection is completed, the bidirectional air pump 18 and all flow control valves 15 are turned off to stop the delivery and extrusion of the adhesive.

[0048] Operators can observe the remaining amount of adhesive in the glue tubes at any time through the observation slots 23 on the surface of the main glue tube 2 and the auxiliary glue tube 12, and through the tempered glass 24 fixed inside, so as to replenish the adhesive in a timely manner.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
