Abstract
Description
Technical Field
[0001] This utility model belongs to the field of nipple patch production and processing technology, specifically relating to a nipple patch silicone gel application device. Background Technology
[0002] Nipple covers are adhesive pads placed on the nipples to cover the areolas. They provide an invisible bra-like effect, making them comfortable, safe, and aesthetically pleasing. Visually, they also serve a decorative purpose, offering a fashionable, trendy, convenient, and contemporary look. Nipple covers are typically designed for women. During production, silicone gel is applied to the inside of the nipple cover. After high-temperature treatment, the silicone gel forms a highly adhesive film on the inside of the nipple cover, ensuring a tight fit to the user's body.
[0003] However, in the current technology for nipple patch production, the silicone gel application step is mostly done by workers using a hand brush to apply the silicone gel liquid inside the nipple patch. This process is inefficient, and manual application is often uneven and may result in missed areas, affecting the quality of the nipple patch. Utility Model Content

The threaded cylinder is threadedly connected to the bottom end of a screw. The upper end of the screw is fixedly connected to the bottom end of a hemispherical support. An arc-shaped plate is correspondingly provided above the hemispherical support.
[0007] The bottom front and rear sides of the arc-shaped plate are fixedly connected to the inner sides of the two scrapers, respectively. The middle part of the bottom of the arc-shaped plate is fixedly connected to the outer surface of the arc-shaped tube. A foot switch is fixedly installed at the bottom of the frame.
[0008] Furthermore, the four corners of the bottom surface of the lifting plate are fixedly connected to the upper ends of four telescopic rods and four springs, respectively, and the bottom ends of the four telescopic rods and four springs are fixedly connected to the upper end of the frame.
[0009] Furthermore, the four springs are respectively sleeved on the outside of the four telescopic rods, and the upper surface of the lifting plate is fixedly connected to the bottom ends of the two pressing plates on the left and right sides respectively.
[0010] Furthermore, the middle portions of the front and rear sides of the arc-shaped plate are respectively fixedly connected to the front and rear sides of the bottom end of the support frame, and the middle portion of the upper end of the support frame is fixedly connected to the fixed pipe.
[0011] Furthermore, the fixed tube is also fixedly connected to the arc-shaped plate and the bottom end of the fixed tube is connected to the arc-shaped tube. The upper end of the outer surface of the fixed tube is provided with a threaded groove that is threadedly connected to the bottom end of the connecting tube.
[0012] Furthermore, the second connecting pipe is rotatably connected to the front end of the support plate via a bearing, and the rear end of the support plate is fixedly connected to the front end of the fixing frame.
[0013] Furthermore, the upper side of the second connecting pipe is fixedly connected to the second gear, the second gear meshes with the first gear, the first gear is fixedly mounted on the motor output shaft, and the bottom end of the motor is fixedly connected to the upper end of the support plate.
[0014] Furthermore, the motor input terminal is electrically connected to the foot switch output terminal, the upper end of the second connecting pipe is rotatably connected to the front end of the first connecting pipe through a sealed bearing, and the rear end of the first connecting pipe is fixedly connected to the left side of the liquid storage tank.
[0015] Furthermore, the bottom surface of the liquid storage tank is fixedly connected to the upper surface of the fixing frame, a piston plate is sleeved inside the liquid storage tank, the right side of the piston plate is fixedly connected to the upper end of the connecting frame, and the connecting frame is sleeved in the slot opened in the middle of the right side of the liquid storage tank.

[0017] The technical effects achieved by this utility model are as follows:
[0018] In this invention, when applying silicone gel to the inside of a nipple cover, the nipple cover can be placed on a hemispherical support. A spring force pushes the lifting plate and hemispherical support upwards, causing the inner side of the nipple cover to adhere to the scraper. At this time, the user can use their foot to press a foot switch to control the retraction of the electric push rod and the operation of the motor. This causes the piston plate to move to the left, squeezing the silicone gel from the reservoir into the inner side of the nipple cover via connecting pipe one, connecting pipe two, and an arc-shaped pipe. When the motor operates, gears one and two drive connecting pipe two, the fixing pipe, and the arc-shaped plate to rotate. The circular motion of the arc-shaped plate, arc-shaped pipe, and scraper evenly coats the inner side of the nipple cover with silicone gel, effectively improving the overall production efficiency of the nipple cover and ensuring the quality of the nipple cover by preventing any missed areas.
[0019] This invention connects the hemispherical support to the lifting plate by setting a screw and a threaded cylinder, and connects the fixing pipe and the connecting pipe by two threads. When using this device to process nipple covers, the hemispherical support and the arc plate can be disassembled and replaced according to the required size of the nipple cover. This allows the size of the hemispherical support, the arc plate and the scraper to match the size of the nipple cover, so that the scraper and the hemispherical support fit tightly to the inner and outer sides of the nipple cover, ensuring the silicone gel application effect and making the silicone gel fully cover the inner side of the nipple cover, effectively improving the applicability of this device.

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0028] like Figure 1-5As shown, a silicone gel applicator for applying nipple covers includes a frame 1. The upper end of the frame 1 is fixedly connected to the bottom end of both a closed frame 2 and a fixed frame 3. A lifting plate 14 is fitted inside the closed frame 2. The middle part of the upper surface of the lifting plate 14 is fixedly connected to the bottom end of a threaded cylinder 16. The threaded cylinder 16 is threadedly connected to the bottom end of a screw 15. The upper end of the screw 15 is fixedly connected to the bottom end of a hemispherical support 5. An arc-shaped plate 17 is correspondingly provided above the hemispherical support 5.
[0029] The bottom end of the arc plate 17 is fixedly connected to the inner sides of the two scrapers 18 on both the front and rear sides, and the bottom end of the arc plate 17 is fixedly connected to the outer surface of the arc tube 26. A foot switch 29 is fixedly installed at the bottom end of the frame 1.
[0030] The four corners of the bottom surface of the lifting plate 14 are fixedly connected to the upper ends of the four telescopic rods 13 and the four springs 12, respectively, and the bottom ends of the four telescopic rods 13 and the four springs 12 are fixedly connected to the upper end of the frame 1.
[0031] Four springs 12 are respectively sleeved on the outside of four telescopic rods 13. The upper surface of the lifting plate 14 is fixedly connected to the bottom of two pressing plates 4 on the left and right sides respectively. When using this device, the user can sit in front of the frame 1 and use both arms to push the pressing plate 4 down so that the lifting plate 14 can be lowered to squeeze the telescopic rods 13 and springs 12. When the hemispherical support 5 is lowered to a suitable height, the user places the nipple cover to be processed on the hemispherical support 5 with the inside of the nipple cover facing up. Then the user slowly removes his arms from the pressing plate 4 and uses the elastic force of the spring 12 to push the lifting plate 14, hemispherical support 5 and nipple cover up so that the inside of the nipple cover moves up to fit with the scraper 18, which makes it easy for the user to quickly install and remove the nipple cover.
[0032] The middle parts of the front and rear sides of the arc plate 17 are fixedly connected to the front and rear sides of the bottom end of the support frame 19, respectively, and the middle part of the upper end of the support frame 19 is fixedly connected to the fixed tube 20.
[0033] The fixing tube 20 is also fixedly connected to the arc plate 17, and the bottom end of the fixing tube 20 is connected to the arc tube 26. The upper end of the outer surface of the fixing tube 20 is provided with a threaded groove and is threadedly connected to the bottom end of the connecting tube 21. The hemispherical support 5 is connected to the lifting plate 14 by setting the screw 15 and the threaded cylinder 16, and the fixing tube 20 is threadedly connected to the connecting tube 21. When using this device to process nipple covers, the hemispherical support 5 and the arc plate 17 can be disassembled and replaced according to the required size of the nipple cover, so that the size of the hemispherical support 5, the arc plate 17 and the scraper 18 are adapted to the size of the nipple cover, so that the scraper 18 and the hemispherical support 5 are tightly attached to the inner and outer sides of the nipple cover, ensuring the silicone gel coating effect and making the silicone gel fully cover the inner side of the nipple cover, effectively improving the applicability of this device.
[0034] The connecting pipe 21 is rotatably connected to the front end of the support plate 23 via a bearing, and the rear end of the support plate 23 is fixedly connected to the front end of the fixing frame 3.
[0035] The upper side of the connecting tube 21 is fixedly connected to the gear 25. The gear 25 meshes with the gear 1 24. The gear 1 24 is fixedly mounted on the output shaft of the motor 22. The bottom end of the motor 22 is fixedly connected to the upper end of the support plate 23. When applying silicone gel, the user can use the foot pedal switch 29 to control the motor 22 to work. The gear 1 24 and the gear 25 drive the connecting tube 21, the fixed tube 20 and the arc plate 17 to rotate. At this time, the rotation direction of the arc plate 17 is the same as the tightening direction of the fixed tube 20 and the screw 15, thereby preventing the fixed tube 20 and the screw 15 from disengaging from the connecting tube 21 and the threaded cylinder 16 respectively when the arc plate 17 rotates.
[0036] The input terminal of motor 22 is electrically connected to the output terminal of foot switch 29. The upper end of connecting pipe 21 is rotatably connected to the front end of connecting pipe 7 through a sealed bearing. The rear end of connecting pipe 7 is fixedly connected to the left side of liquid storage tank 8.
[0037] The bottom surface of the liquid storage tank 8 is fixedly connected to the upper surface of the fixing frame 3. A piston plate 28 is installed inside the liquid storage tank 8. The right side of the piston plate 28 is fixedly connected to the upper end of the connecting frame 11. The connecting frame 11 is installed in the slot 27 opened in the middle of the right side of the liquid storage tank 8.
[0038] The bottom end of the connecting frame 11 is fixedly connected to the right end of the electric push rod 6. The fixed end of the electric push rod 6 is also fixedly connected to the left and right sides of the fixing frame 3. The right side of the upper surface of the liquid storage tank 8 is fixedly connected to the bottom end of the filling pipe 9. A valve 10 is provided at the upper end of the filling pipe 9. When silicone gel liquid needs to be added to the liquid storage tank 8, the electric push rod 6 can be extended to move the piston plate 28 to the rightmost end of the liquid storage tank 8. Then, the valve 10 is opened to fill the liquid storage tank 8 with silicone gel liquid through the filling pipe 9, and then the valve 10 is closed.
[0039] The working principle of this utility model is as follows: When using this device to process silicone gel coating on nipple covers, the user can first replace the hemispherical support 5 and the arc plate 17 with the specifications that are suitable for the nipple cover according to the size of the nipple cover to be processed. Then the user can sit in front of the frame 1 and use both arms to push the pressing plate 4 down so that the lifting plate 14 can be lowered to squeeze the telescopic rod 13 and the spring 12. When the hemispherical support 5 is lowered to a suitable height, the user places the nipple cover to be processed on the hemispherical support 5 with the inner side of the nipple cover facing up. Then the user slowly removes his arms from the pressing plate 4 and uses the elastic force of the spring 12 to push the lifting plate 14, the hemispherical support 5 and the nipple cover up so that the inner side of the nipple cover moves up to fit with the scraper 18.
[0040] At this time, the user can use the foot pedal switch 29 to control the retraction of the electric push rod 6 and the operation of the motor 22. When the electric push rod 6 retracts, the piston plate 28 moves to the left, squeezing out the silicone gel in the reservoir 8 and flowing into the inside of the nipple cover through the connecting tube 1 7, connecting tube 2 21, and arc-shaped tube 26. When the motor 22 is working, the gear 1 24 and gear 2 25 drive the connecting tube 2 21, the fixing tube 20, and the arc-shaped plate 17 to rotate. The circular motion of the arc-shaped plate 17, the arc-shaped tube 26, and the scraper 18 evenly spreads the silicone gel on the inside of the nipple cover. Then, the user can remove the foot from the foot pedal switch 29 to turn off the electric push rod 6 and the motor 22, and press the lifting plate 14 again to lower it and remove the nipple cover from the hemispherical support 5.
[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
