Description

Technical Field

[0001] This utility model relates to the field of glue applicator technology, specifically a glue applicator for aluminum alloy doors and windows. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes, or simply aluminum doors and windows.

[0003] When installing aluminum alloy doors and windows, it is necessary to apply sealant along the edges of the aluminum alloy doors and windows and the joints with the windows. Current technology usually uses a glue gun to apply the sealant. The glue gun requires the worker to squeeze with both hands to squeeze the sealant out of the tube and then apply it to the edges of the aluminum alloy door frame, which is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum alloy door and window sealant applicator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy door and window caulking machine, comprising a tank, an inner cylinder inside the tank, a caulking chamber inside the inner cylinder, a pressurizing chamber between the outer wall of the inner cylinder and the inner wall of the tank, a discharge cap threadedly installed at the center of the top of the tank, a guide pipe communicating with the caulking chamber inserted at the center of the discharge cap, and an extrusion plate slidably installed inside the inner cylinder;

[0006] A miniature booster pump is provided on one side of the top of the tank, and the output end of the miniature booster pump is connected to the pressurization chamber through a booster pipe.

[0007] A glue outlet tube that communicates with the guide tube is inserted into the center of the top of the discharge cap, and a glue outlet head is provided at the free end of the glue outlet tube;

[0008] An air inlet is provided at the bottom of one side of the inner cylinder, and the glue storage chamber and the pressurization chamber are connected through the air inlet.

[0009] A handle is provided on one side of the outer wall of the tank.

[0010] The tank has a feed pipe inserted into one side of its top, which communicates with the glue storage chamber, and a feed valve is fixedly installed on the feed pipe.

[0011] A pressure relief valve is embedded in the center of the bottom of the tank.

[0012] The dispensing tube has an L-shaped structure.

[0013] The extrusion plate has a disc-shaped structure, and an elastic rubber ring is fitted around the edge of the extrusion plate. The outer side of the elastic rubber ring is in contact with the inner wall of the inner cylinder.

[0014] The dispensing head has a frustum-shaped structure, and a dispensing hole that communicates with the dispensing tube is opened through the axis of the dispensing head.

[0015] A baffle is fixedly installed inside the inner cylinder on one side above the air inlet. The baffle is located below the extrusion plate, and a through hole is formed at the center of the surface of the baffle.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention stores adhesive in a storage chamber and uses an extrusion plate to shield the adhesive within the storage chamber, preventing it from entering the pressurization chamber through the air inlet. When applying adhesive to the edges of aluminum alloy doors and windows, the dispensing head is aligned with the edge, and a micro booster pump is activated. This increases the atmospheric pressure within the pressurization chamber, and the air inlet further increases the atmospheric pressure below the extrusion plate, pushing it upwards along the inner cylinder. The extrusion plate then compresses the adhesive in the storage chamber, causing it to flow into the guide pipe, then out through the dispensing pipe, and finally through the dispensing head to the edge of the aluminum alloy door or window, thus completing the adhesive application process. This method is simple to operate and easy to use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-5 This utility model provides a technical solution: an aluminum alloy door and window glue applicator, comprising a tank 10, an inner cylinder 50 inside the tank 10, the inner cylinder 50 being cylindrical in shape and concentrically arranged with the tank 10, forming a glue storage cavity inside the inner cylinder 50, a feed pipe 17 communicating with the glue storage cavity being inserted into one side of the top of the tank 10, a feed valve 16 being fixedly installed on the feed pipe 17, and a pressure relief valve 12 being embedded in the center of the bottom of the tank 10, for when glue needs to be applied... When filling the glue into the storage chamber, first open the pressure relief valve 12, then open the feed valve 16, and then fill the glue into the storage chamber through the feed valve 16 and the feed pipe 17. When filling the glue into the storage chamber, the glue will exert pressure on the extrusion plate 30, causing the extrusion plate 30 to slide downward. The air below the extrusion plate 30 will be discharged from the pressure relief valve 12 to ensure atmospheric pressure balance. After the glue filling is completed, close both the pressure relief valve 12 and the feed valve 16.

[0026] A pressurized chamber is formed between the outer wall of the inner cylinder 50 and the inner wall of the tank body 10. A discharge cap 13 is threadedly installed at the center of the top of the tank body 10. A guide pipe 20 communicating with the glue storage chamber is inserted into the center of the discharge cap 13. An extrusion plate 30 is slidably installed inside the inner cylinder 50. A micro booster pump 14 is provided on one side of the top of the tank body 10. The output end of the micro booster pump 14 is connected to the pressurized chamber through a booster pipe 15. A glue outlet pipe 40 communicating with the guide pipe 20 is inserted into the center of the top of the discharge cap 13. A glue outlet head 41 is provided at the free end of the glue outlet pipe 40. An air inlet 51 is opened at the bottom of one side of the inner cylinder 50. The glue storage chamber and the pressurized chamber are connected through the air inlet 51.

[0027] When applying sealant to the edges of aluminum alloy doors and windows, the dispensing head 41 is aligned with the edge of the aluminum alloy door and window, and then the micro booster pump 14 is turned on. The micro booster pump 14 increases the atmospheric pressure in the pressurization chamber. Through the air inlet 51, the atmospheric pressure below the extrusion plate 30 continuously increases, thereby pushing the extrusion plate 30 to move upward along the inner cylinder 50. The extrusion plate 30 squeezes the sealant in the sealant storage chamber. After being squeezed, the sealant flows into the guide pipe 20, and then flows out through the dispensing pipe 40 and is discharged to the edge of the aluminum alloy door and window through the dispensing head 41, thus achieving the sealant application. This method is simple to operate and easy to use.

[0028] The tank 10 has a handle 11 on one side of its outer wall. In actual use, workers can lift the glue applicator by the handle 11 to make it easier to apply glue along the edge of the aluminum alloy doors and windows.

[0029] The dispensing tube 40 has an L-shaped structure, so that when the worker lifts the tank 10 vertically, the dispensing head 41 at the end of the dispensing tube 40 can be perpendicular to the vertically installed aluminum alloy door and window, which facilitates the application of adhesive to the edges of the vertically installed aluminum alloy door and window.

[0030] The extrusion plate 30 has a disc-shaped structure, with an elastic rubber ring fitted around its edge. The outer side of the elastic rubber ring contacts the inner wall of the inner cylinder 50. The upper part of the extrusion plate 30 is used to store glue, and the lower part of the extrusion plate 30 is connected to the pressure chamber through the air inlet 51. The working principle of the extrusion plate 30 is similar to that of the rubber stopper of a syringe. When glue needs to be applied, the micro booster pump 14 is turned on to increase the atmospheric pressure in the pressure chamber. Through the action of the air inlet 51, the atmospheric pressure below the extrusion plate 30 continuously increases, thereby pushing the extrusion plate 30 to move upward along the inner cylinder 50. The extrusion plate 30 squeezes the glue in the glue storage chamber. After being squeezed, the glue flows into the guide pipe 20, then flows out through the glue outlet pipe 40, and is discharged to the edge of the aluminum alloy door and window through the glue outlet head 41, thus realizing the glue application. This method is simple to operate and easy to use.

[0031] The dispensing head 41 has a frustum-shaped structure. A dispensing hole that communicates with the dispensing pipe 40 is opened through the axis of the dispensing head 41. When the glue in the glue storage chamber flows into the dispensing pipe 40 through the guide pipe 20, the glue then flows into the dispensing head 41 and flows through the dispensing hole to the edge of the aluminum alloy door and window.

[0032] To prevent the extrusion plate 30 from sliding to the bottom of the inner cylinder 50 and to prevent the glue above the extrusion plate 30 from flowing into the pressurization chamber through the air inlet 51, a baffle 52 is fixedly installed inside the inner cylinder 50 on the side above the air inlet 51. The baffle 52 is located below the extrusion plate 30 and blocks the extrusion plate 30. When glue is injected into the glue storage chamber through the feed valve 16 and the air inlet pipe 17, the glue exerts pressure on the extrusion plate 30, causing the extrusion plate 30 to move downward. When the extrusion plate 30 moves to the position of the baffle 52, the baffle 52 blocks the extrusion plate 30, preventing the extrusion plate 30 from descending further.

[0033] In order to ensure that the extrusion plate 30 and the pressurization chamber can be connected through the air inlet 51, a through hole is provided in the center of the surface of the baffle 52. When the micro booster pump 14 is turned on, the atmospheric pressure in the pressurization chamber is increased by the micro booster pump 14. Through the action of the air inlet 51 and the through hole, the atmospheric pressure below the extrusion plate 30 is continuously increased, thereby pushing the extrusion plate 30 to move upward along the inner cylinder 50, and the extrusion plate 30 squeezes the glue in the glue storage chamber.

[0034] Working principle: First, open the pressure relief valve 12, then open the feed valve 16. The glue is then poured into the glue storage chamber through the feed valve 16 and feed pipe 17. As the glue is poured into the storage chamber, it exerts pressure on the extrusion plate 30, causing it to slide downwards. Air trapped beneath the extrusion plate 30 is released through the pressure relief valve 12, ensuring atmospheric pressure balance. After glue filling is complete, close both the pressure relief valve 12 and the feed valve 16. When applying glue to the edges of aluminum alloy doors and windows, align the glue nozzle 41 with the aluminum alloy door. At the edge of the window, the micro booster pump 14 is turned on to increase the atmospheric pressure in the pressurization chamber. Through the air inlet 51, the atmospheric pressure below the extrusion plate 30 is continuously increased, thereby pushing the extrusion plate 30 to move upward along the inner cylinder 50. The extrusion plate 30 squeezes the glue in the glue storage chamber. After being squeezed, the glue flows into the guide pipe 20, and then flows out through the glue outlet pipe 40 and is discharged to the edge of the aluminum alloy door and window through the glue outlet head 41, thus realizing the glue application. This method is simple to operate and easy to use.

[0035] Based on 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.
