Description

Technical Field

[0001] This utility model belongs to the technical field of glue application mechanism, and relates to an automatic glue application mechanism for the end of a bent pipe. Background Technology

[0002] Pipe bending is performed using a complete set of bending equipment, which includes two processes: cold bending and hot bending. Most machines and pipes utilize pipe bending. When connecting pipes to joints (such as sleeves and flanges), adhesive needs to be applied to the ends of the pipes to fill the gaps and prevent liquid or gas leakage; therefore, an adhesive application mechanism is used.

[0003] A glue-applying device with anti-drip function is disclosed in Chinese Patent CN221311285U. It is equipped with an extraction device, which includes a glue suction tube, a fixing plate, a glue storage tank, a connecting tube, a negative pressure generator, and a glue guide tube. One end of the glue suction tube is fixedly connected to the surface of the glue outlet, and the other end passes through the side wall of the glue applicator and is fixedly connected to the glue storage tank. The lower end of the glue storage tank is fixedly connected to the fixing plate, which is fixedly connected to the side wall of the glue applicator. The upper end of the glue storage tank is fixedly connected to the connecting tube, and the other end of the connecting tube is fixedly connected to the negative pressure generator. The lower end of the glue storage tank is fixedly connected to the glue guide tank, and the other end of the glue guide tube passes through the processing plate and is connected to the interior of the glue storage tank.

[0004] This adhesive application equipment dispenses adhesive through a dispensing head. However, when applying adhesive to the surface of a cylindrical object, the adhesive that drips onto the surface tends to slide down the cylindrical surface and fall off, resulting in waste.

[0005] To solve the above problems, this utility model proposes an automatic glue application mechanism for the end of a bent pipe. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an automatic glue application mechanism for the end of a bent pipe.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes an L-shaped base, which is composed of a vertical section and a horizontal section. A storage box is fixedly connected to the top of one side of the vertical section of the base. An arc-shaped connecting plate is raised and lowered directly below the storage box. A spreading rod is fixedly connected to both ends of the bottom surface of the connecting plate. Several telescopic tubes are fixedly connected at intervals to the bottom of the storage box. The bottom end of each telescopic tube is fixedly connected through the connecting plate.

[0008] A pneumatic chuck is rotatably mounted on the bottom of one side of the vertical section of the base. A bent tube is movably mounted on the pneumatic chuck, and the applicator stick moves against the outer surface of the bent tube.

[0009] Furthermore, the vertical section of the base is fixedly connected to the top of one end of the horizontal section of the base, and the storage box is located directly above the horizontal section of the base.

[0010] Furthermore, a motor is fixedly connected to the side of the base away from the storage box, and the output shaft of the motor rotates through the base, with a pneumatic chuck coaxially fixedly connected to the end of the output shaft of the motor.

[0011] Furthermore, two cylinders are symmetrically fixedly connected to the bottom of the storage box. Both cylinders are vertically arranged, and the bottom of the telescopic ends of the two cylinders are fixedly connected to the top surface of the connecting plate. Several telescopic tubes are located between the two cylinders.

[0012] Furthermore, the telescopic tube includes a hollow tube and a piston rod. The top end of the hollow tube is fixedly connected to the bottom of the storage box, and the top end of the hollow tube is flush with the bottom surface of the inner cavity of the storage box. The top end of the piston rod is vertically slidably disposed inside the hollow tube, and the bottom end of the piston rod is fixedly connected through a connecting plate. A through hole is opened on the piston rod, and a glue valve is fixedly installed inside the through hole.

[0013] Furthermore, a feed inlet is provided on the top of one side of the storage box, and a sealing cap is provided on the feed inlet.

[0014] Furthermore, the connecting plate gradually slopes downward from the middle to both ends, and the bottom end of the piston rod is located above the two applicator sticks.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The automatic glue application mechanism at the end of the bent pipe is equipped with an application rod. The connecting plate is driven downward by a cylinder, which can bring the application rod against the outer surface of the bent pipe. This allows the piston rod to discharge glue between the two application rods. The application rods will block the glue, preventing it from dripping downward and reducing waste.

[0017] 2. The automatic glue application mechanism at the end of the bent tube is equipped with a piston rod. The top of the piston rod is slidably disposed inside the hollow tube. When the piston rod moves downward, it can draw glue into the hollow tube, making it easy to discharge the glue for application. After the glue application is completed, the piston rod moves upward to push the glue in the hollow tube back into the storage box for continued 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. 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.

[0025] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: An automatic glue-applying mechanism for the end of a bent pipe includes an L-shaped base 1, which is composed of a vertical section and a horizontal section. The vertical section of the base 1 is fixedly connected to the top of one end of the horizontal section of the base 1. The horizontal section of the base 1 provides support.

[0026] A storage box 3 is fixedly connected to the top of one side of the vertical section of the base 1, and the storage box 3 is located directly above the horizontal section of the base 1.

[0027] A feed inlet is provided on the top of one side of the storage tank 3, and a sealing cap is provided on the feed inlet. The feed inlet facilitates the introduction of adhesive into the storage tank 3.

[0028] An arc-shaped connecting plate 8 is installed at the bottom of the storage box 3.

[0029] Two cylinders 7 are symmetrically fixedly connected to the bottom of the storage box 3, and both cylinders 7 are vertically arranged. The bottom of the telescopic ends of the two cylinders 7 are fixedly connected to the top surface of the connecting plate 8. The connecting plate 8 is driven to move vertically up and down by the cooperation of the two cylinders 7.

[0030] A spreading rod 9 is fixedly connected to both ends of the bottom surface of the connecting plate 8. Several telescopic tubes are fixedly connected at intervals to the bottom of the storage box 3, and these telescopic tubes are located between two cylinders 7. The bottom end of each telescopic tube is fixedly inserted through the connecting plate 8, causing the connecting plate 8 to move the bottom end of the telescopic rod.

[0031] The telescopic tube includes a hollow tube 6 and a piston rod 10. The top end of the hollow tube 6 is fixedly connected to the bottom of the storage box 3, and the top end of the hollow tube 6 is flush with the bottom surface of the inner cavity of the storage box 3. This allows the adhesive in the storage box 3 to enter the interior of the hollow tube 6.

[0032] The top end of the piston rod 10 is vertically slidably disposed inside the hollow tube 6, and the bottom end of the piston rod 10 is fixedly inserted through the connecting plate 8. The connecting plate 8 drives the piston rod 10 to move, and the top end of the piston rod 10 slides inside the hollow tube 6.

[0033] The connecting plate 8 slopes gradually downwards from the middle to both ends. The bottom end of the piston rod 10 is located above the two applicator sticks 9. This allows the piston rod 10 to discharge adhesive between the two applicator sticks 9, and the two applicator sticks 9 to block the adhesive.

[0034] A through hole 11 is provided on the piston rod 10, and a dispensing valve 12 is fixedly installed inside the through hole 11. The dispensing valve 12 is a device used for applying, potting, or dispensing adhesive or other liquids, and is an existing product. The dispensing valve 12 controls the flow of adhesive for automatic application.

[0035] A pneumatic chuck 4 is rotatably mounted on the bottom of one side of the vertical section of the base 1. The pneumatic chuck 4 is a device that converts the pressure in the air source into clamping force, and is an existing product.

[0036] A motor 2 is fixedly connected to the side of the base 1 away from the storage box 3. The output shaft of the motor 2 rotates through the base 1, and a pneumatic chuck 4 is coaxially fixedly connected to the end of the output shaft of the motor 2. The motor 2 drives the pneumatic chuck 4 to rotate.

[0037] A bent tube 5 is movably mounted on the pneumatic chuck 4, and an applicator 9 is movably abutted against the outer surface of the bent tube 5. The pneumatic chuck 4 drives the bent tube 5 to rotate, and the bent tube 5 rotates at the bottom of the applicator 9, so that the applicator 9 can evenly apply the adhesive.

[0038] Working principle:

[0039] When in use, fix one end of the bend 5 to the pneumatic chuck 4 so that the end of the bend 5 is directly below the connecting plate 8.

[0040] Start cylinder 7, which pushes connecting plate 8 downward, causing applicator 9 to move downward. Connecting plate 8 drives the bottom end of piston rod 10 downward, causing the top end of piston rod 10 to slide on hollow tube 6, allowing adhesive from storage tank 3 to enter hollow tube 6. Continue until applicator 9 comes into contact with the outer surface of curved tube 5.

[0041] Start the dispensing valve 12 and motor 2.

[0042] The dispensing valve 12 will pass the adhesive from the hollow tube 6 into the through hole 11, and then onto the surface of the curved tube 5. The adhesive will be located between the two applicator sticks 9.

[0043] The output shaft of motor 2 drives pneumatic chuck 4 and bend tube 5 to rotate, causing bend tube 5 to rotate at the bottom of applicator 9. When rotating, applicator 9 will apply glue, thereby automatically applying glue to the end of bend tube 5.

[0044] After the adhesive is applied, cylinder 7 drives connecting plate 8 to move upward, causing applicator 9 to leave the curved tube 5. This causes the top of piston rod 10 to move into hollow tube 6, pushing the adhesive inside hollow tube 6 back into storage tank 3.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
