Technical Field

[0001] This utility model relates to the field of tapping and untapping equipment technology, and in particular to an automated tapping and untapping device for a water heater proportional valve. Background Technology

[0002] The proportional valve of a water heater requires a sealing gasket during the production process. During the post-processing of the sealing gasket, a ring of inner diameter edge material will be attached to its inner ring. At this time, the inner diameter edge material needs to be removed in order to gradually become a qualified product.

[0003] When processing inner diameter edge material, in most cases, workers manually remove the inner diameter edge material. Manual processing of inner diameter edge material is not only inefficient, time-consuming and labor-intensive, but also has a high defect rate, making it easy to produce unqualified products.

[0004] To address this, an automated valve switching device for water heaters is proposed. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 5As shown in the figure, a specific embodiment of this utility model provides an automated cutting and pulling device for a proportional valve of a water heater, including an upper base plate 1, an upper template 2 fixedly connected to the bottom end of the upper base plate 1, a bottom plate 3 provided at the bottom of the upper template 2, and a punch fixing plate 4 fixedly connected to the top end of the bottom plate 3; the punch fixing plate 4 is provided with a cutting and pulling component for removing inner diameter edge material. By setting the cutting and pulling component, the inner diameter edge material in the sealing gasket 7 can be removed, thereby replacing manual processing, improving efficiency, and reducing the occurrence of defective products. The cutting and pulling component includes a stripping plate 5 provided at the top of the punch fixing plate 4, a punch rod 6 slidably connected to the stripping plate 5, a sealing gasket 7 placed at the top end of the stripping plate 5, and the punch rod 6 inserted into the inner cavity of the sealing gasket 7 and in contact with the bottom end face of the inner diameter edge material. The upper template 2 is provided with a discharge hole 8.

[0027] like Figures 2 to 4 As shown, specifically, when processing the inner diameter edge material of the sealing gasket 7, the sealing gasket 7 must first be placed on the unloading plate 5. A limiting groove 9 is provided on the base plate 3. A moving block 10 is fixedly connected to the bottom end of the punch fixing plate 4, and the moving block 10 is slidably connected in the limiting groove 9. A motor 11 is fixedly installed on the base plate 3, and a threaded rod 12 is fixedly connected to the output shaft of the motor 11. The threaded rod 12 is threadedly connected to the moving block 10. When the motor 11 is started, it drives the threaded rod 12 to rotate, thereby causing the moving block 10 to move in the limiting groove 9. The moving block 10 moves the top punch fixing plate 4 and the top unloading plate 5. The unloading plate 5 moves out of the bottom of the upper template 2, making it easier for the operator to place the sealing gasket 7 on the top of the unloading plate 5. When the sealing gasket 7 is placed on the top surface of the unloading plate 5, the punch rod 6 can enter the inner cavity of the sealing gasket 7, and the top surface of the punch rod 6 is in contact with the bottom surface of the inner diameter edge material in the sealing gasket 7. After the sealing gasket 7 is placed, the reverse drive motor 11 causes the punch fixing plate 4 to move in the reverse direction to reset.

[0028] like Figures 3 to 4As shown, specifically, a cylinder 13 is fixedly installed on the base plate 3, and the output end of the cylinder 13 is fixedly connected to the upper base plate 1. A receiving groove 14 for transferring inner diameter edge material is provided between the upper base plate 1 and the upper template 2. The bottom end of the upper template 2 is provided with a concave arc opening 15 that matches the protrusion on the sealing gasket 7, and the concave arc opening 15 is connected to the discharge hole 8. The punch rod 6 is fixedly installed on the punch fixing plate 4. A guide rod 16 and a spring 17 are fixedly installed on the punch fixing plate 4, and the spring 17 is fixedly connected to the unloading plate 5. The upper base plate 1 and the upper template 2 are provided with guide holes 18 for the guide rod 16 to pass through. After the sealing gasket 7 is placed in the above process, the cylinder 13 is activated to push the upper base plate 1 to move the upper template 2 downward. The guide rod 16 gradually enters the guide hole 18. The guide rod 16 serves as a position guide to prevent the upper base plate 1 and the upper template 2 from moving downward. During the descent, the position deviates significantly, and the upper template 2 gradually approaches the sealing gasket 7 at the bottom, causing the protrusion on the sealing gasket 7 to fit against the concave arc opening 15. At this time, the upper template 2 and the sealing gasket 7 are in close contact and fit together. As the upper template 2 continues to move downward, it pushes the sealing gasket 7 at the bottom and the stripper plate 5 downward. At this time, the stripper plate 5 and the sealing gasket 7 slide downward on the punch rod 6. The spring 17 is compressed and generates a reaction force. The sealing gasket 7 is held between the upper template 2 and the stripper plate 5 and slides downward on the punch rod 6, which causes the punch rod 6 and the sealing gasket 7 to enter the discharge hole 8. The punch rod 6 applies a force to the inner diameter edge material in the sealing gasket 7, thereby pulling the inner diameter edge material upward and separating it from the sealing gasket 7. The punch rod 6 pulls the inner diameter edge material upward and pushes it into the receiving groove 14.

[0029] like Figures 3 to 5 As shown, specifically, the port of the receiving trough 14 is fixedly connected to a channel 19 for transferring inner diameter edge material, and the bottom end of the channel 19 is fixedly connected to a collection box 20, the bottom end of the collection box 20 is provided with an openable sealing plate, and the tail end of the channel 19 is fixedly installed with a centrifugal fan 21 capable of generating suction. A filter screen 22 is provided on the channel 19. In the above process, after the inner diameter edge material is pushed into the receiving trough 14, the centrifugal fan 21 is started to generate suction, thereby sucking up the inner diameter edge material in the receiving trough 14 and making it pass through the channel 19. 9 moves to filter screen 22, and after the centrifugal fan 21 stops driving, the inner diameter edge material automatically falls into the collection box 20 at the bottom under the suction of the wind. The inner diameter edge material can be taken out by the staff opening the sealing plate at the bottom. After the inner diameter edge material on the sealing gasket 7 is removed, the cylinder 13 is started to drive the upper plate 1 and the upper template 2 to move upward and reset. After the upper template 2 is separated from the sealing gasket 7 at the bottom, the sealing gasket 7 can be taken out. The unloading plate 5 can be moved and reset under the reaction force of the spring 17.
