They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0032] The present invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1 to 12 As shown, an automatic inner cover pressing device mainly consists of a frame 1, a press guide mechanism 2, a positioning mechanism 3, a clamping mechanism 4, and an inner cover feeding mechanism 5. In order to make the automatic inner cover pressing device compact and reduce the space occupation, while ensuring the stability of the above structure during use, the press guide mechanism 2 is installed above the frame 1, the positioning mechanism 3 is installed at the overhead position of the press guide mechanism 2, the clamping mechanism 4 is installed on one side of the press guide mechanism 2 to clamp the box body 7, and the inner cover feeding mechanism 5 is installed on the other side of the press guide mechanism 2 to realize the installation of the inner cover 8 on the box body 7. Specifically, the positioning mechanism 3 has a positioning block 3-7 and a positioning cylinder 3-3 for driving the positioning block 3-7. The clamping mechanism 4 includes a clamping block 4-7 and a clamping cylinder 4-3 for driving the clamping block 4-7. The positioning block 3-7 and the clamping block 4-7 have clamping surfaces 6 that are adapted to the box body 7. The clamping surfaces 6 are arc-shaped or other shapes, mainly to adapt to the shape of the box body 7 so as to clamp the box body 7 and ensure the stability of the box body 7 during the assembly process. The inner cover feeding mechanism 5 includes an inner cover feeding assembly 5-1 and an inner cover feeding assembly 5-2. The inner cover feeding assembly 5-1 includes a feeding drive cylinder 5-1-7, a feeding bottom push plate 5-1-8, and an inner cover feeding barrel 5-1-9. The feeding bottom push plate 5-1-8 is installed at the output end of the feeding drive cylinder 5-1-7, and the inner cover feeding barrel 5-1-9 is installed in the output direction of the feeding drive cylinder 5-1-7. The feeding drive cylinder 5-1-7 drives the feeding bottom push plate 5-1-8, which in turn pushes the inner cover located at the lowest end of the inner cover feeding barrel 5-1-9 to move upwards towards the box body 7. Then, the inner cover 8 and the box body 7 are pressed together by the press guide mechanism 2.

[0034] The inner cover feeding assembly 5-1 of the present invention further includes a feeding fixing bracket 5-1-1, a vertical connecting column 5-1-2, an inner cover pre-positioning plate one 5-1-3, an inner cover pre-positioning plate two 5-1-4, a feeding connecting horizontal bottom plate 5-1-5, and a feeding cylinder connecting plate 5-1-6. The feeding fixing bracket 5-1-1 is installed away from the feeding drive cylinder 5-1-7 and on the other side of the inner cover feeding barrel 5-1-9. The purpose is to facilitate the movement of the inner cover 8 at the bottom of the inner cover feeding barrel 5-1-9 to the feeding fixing bracket 5-1-1. The inner cover pre-positioning plate one 5-1-3 and the inner cover pre-positioning plate two 5-1-4 are connected by a vertical connecting column 5-1-2 and a vertical connecting column 5-1-3. -1-4 are all connected to the loading fixing bracket 5-1-1 via the vertical connecting column 5-1-2. In this device, the distance between the inner cover prepositioning plate 1 5-1-3 and the inner cover prepositioning plate 2 5-1-4 is adjustable to adapt to the shape of the inner cover 8. The inner cover prepositioning plate 1 5-1-3 and the inner cover prepositioning plate 2 5-1-4 are both cut to form a prepositioning position 5-1-10 for placing the inner cover 8. The height of the prepositioning position 5-1-10 can be set lower than the bottom of the inner cover loading hopper 5-1-9 so that the inner cover 8 can be moved to the prepositioning position 5-1-10.

[0035] like Figure 12As shown, to further refine the installation position of the inner cover 8 and thus ensure the sealing of the box or bottle, the inner cover feeding assembly 5-2 of this invention includes a feeding transverse slide rail 5-2-1, a feeding transverse slider 5-2-2, a feeding connecting plate 5-2-3, an upper and lower guide slide rail 5-2-4, an upper and lower guide slider 5-2-5, a first-stage extension cylinder 5-2-6, an extension cylinder connecting plate 5-2-7, a second-stage extension cylinder 5-2-8, a clamping cylinder connecting plate 5-2-9, a second clamping cylinder 5-2-10, a first clamping block 5-2-11, a second clamping block 5-2-12, a transverse cylinder fixing seat 5-2-13, a transverse cylinder connecting plate 5-2-14, and a transverse cylinder 5-2-15. The feeding transverse slider 5-2-2 is slidably mounted on the feeding transverse slide rail 5-2-1, and the feeding connecting plate 5-2-3 is mounted on the feeding transverse slide rail 5-2-1. The slider 5-2-2 is vertically arranged between the upper and lower guide slide rails 5-2-4 and the feeding transverse slide rail 5-2-1. The upper and lower guide slider 5-2-5 is slidably mounted on the upper and lower guide slide rails 5-2-4. The first-stage extension cylinder 5-2-6 is mounted on the feeding connecting plate 5-2-3. The extension cylinder connecting plate 5-2-7 is mounted on the output end of the first-stage extension cylinder 5-2-6. The second-stage extension cylinder 5-2-8 is mounted on the extension cylinder connecting plate 5-2-7. The clamping cylinder connecting plate 5-2-9 is mounted on the output end of the second-stage extension cylinder 5-2-8. The second clamping cylinder 5-2-10 is horizontally mounted on the clamping cylinder connecting plate 5-2-9. The first clamping block 5-2-11 and the second clamping block 5-2-12 are mounted on the second clamping cylinder 5-2-10 to clamp the inner cover 8. The stroke of both the first-stage extension cylinder 5-2-6 and the second-stage extension cylinder 5-2-8 is 10mm. In the original position, after the first-stage extension cylinder 5-2-6 and the second-stage extension cylinder 5-2-8 enter the predetermined positioning position 5-1-10 for placing the inner cover 8 without load, the clamping cylinder 2 5-2-10 and the first-stage extension cylinder 5-2-6 extend, driving the clamping block 1 5-2-11 and the clamping block 2 5-2-12 to move upward to the position where the inner cover 8 can be clamped. After the inner cover 8 is clamped, the second-stage extension cylinder 5-2-8 continues to extend, lifting the clamping cylinder 2 5-2-10, the clamping block 1 5-2-11, the clamping block 2 5-2-12 and the inner cover 8 simultaneously by 10mm, finally bringing the inner cover 8 below the inner cover suction nozzle 2-7 in the press guide mechanism 2.

[0036] like Figure 4As shown, the press guide mechanism 2 of the present invention further includes a guide support column 2-1, an upper fixed plate 2-2, a guide sleeve 2-3, a sliding pressure plate 2-4, and a servo motor 2-5. The upper fixed plate 2-2 is installed on the top of the guide support column 2-1 to facilitate the installation of the servo motor 2-5. The guide sleeve 2-3 is sleeved on the outside of the guide support column 2-1. The sliding pressure plate 2-4 is located below the upper fixed plate 2-2 and can be connected to the guide sleeve 2-3, so that the sliding pressure plate 2-4 can move its position with the sliding of the guide sleeve 2-3. The servo motor 2-5 is installed on the top of the upper fixed plate 2-2 and its output end passes through the upper fixed plate 2-2 and connects to the inner cover suction nozzle 2-7. The inner cover suction nozzle 2-7 is installed at the bottom of the sliding pressure plate 2-4. By driving the sliding pressure plate 2-4 with the servo motor 2-5, the position of the inner cover suction nozzle 2-7 can be changed, thereby realizing the suction, pressing and other operations of the inner cover 8.

[0037] To prevent excessive driving force of the servo motor 2-5 from damaging the inner cover suction nozzle 2-7, thereby ensuring the service life of the inner cover suction nozzle 2-7 and reducing usage costs, the press guide mechanism 2 of the present invention also includes a pressure sensor 2-6. The pressure sensor 2-6 is installed between the output end of the servo motor 2-5 and the inner cover suction nozzle 2-7. The servo motor 2-5 drives the sliding pressure plate 2-4 to move up and down, thereby pushing the inner cover suction nozzle 2-7 to move up and down.

[0038] The aforementioned inner cover suction nozzle 2-7 is cylindrical, but can also be of other shapes, which are not limited here. Its main purpose is to suck up the inner cover 8. An exhaust port 2-7-1 is provided on the side wall of the inner cover suction nozzle 2-7. The exhaust port 2-7-1 is connected to an externally set vacuum generator to generate negative pressure. Then, through the suction nozzle step portion 2-7-2 formed at the bottom of the inner cover suction nozzle 2-7 and the contact air hole 2-7-3 opened at the bottom of the suction nozzle step portion 2-7-2, it is combined with the inner cover 8 to hold the inner cover 8. Then, it is pressed into the box body 7 to complete the assembly of the inner cover 8 and the box body 7, while ensuring the sealing of the connection.

[0039] To ensure the stability of the positioning mechanism 3 during the positioning process, the positioning mechanism 3 of the present invention further includes a positioning base plate 3-1, on which a positioning cylinder support plate 3-2 is mounted. The positioning cylinder 3-3 is mounted on the positioning cylinder support plate 3-2, and the positioning block 3-7 is mounted on the output end of the positioning cylinder 3-3. Similarly, to ensure the stability of the clamping mechanism 4 during the clamping process, the clamping mechanism 4 of the present invention further includes a clamping base plate 4-1, on which a clamping cylinder support plate 4-2 is mounted. The clamping cylinder 4-3 is mounted on the clamping cylinder support plate 4-2, and the clamping block 4-7 is connected to the output end of the clamping cylinder 4-3. Both the positioning mechanism 3 and the clamping mechanism 4 are driven by cylinders, which further ensures the accuracy of the inner cover 8 installation position.

[0040] To further ensure the stability of the clamping cylinder 4-3 and the positioning cylinder 3-3 during the driving process, a positioning pad 3-4 with a certain height is also installed on the positioning base plate 3-1. A positioning side slide rail 3-5 is fixed on the positioning pad 3-4, and a positioning slider 3-6 is slidably installed on the positioning side slide rail 3-5. The positioning block 3-7 is connected to the positioning slider 3-6. A limit support seat 3-8 is installed on the side of the positioning pad 3-4, and a positioning adjustment rod 3-9 is inserted near the top of the limit support seat 3-8. A clamping pad 4-4 with a certain height is installed on the clamping base plate 4-1. A clamping slide rail 4-5 is installed on the clamping pad 4-4, and a clamping slider 4-6 is installed on the clamping slide rail 4-5. The clamping block 4-7 is installed on the clamping slider 4-6.

[0041] The frame 1 of this invention includes a frame body 1-1 with a frame structure. The frame body 1-1 is mainly formed by steel columns, which provides high structural strength and facilitates manufacturing, reducing manufacturing difficulty. To facilitate the installation of other components, a flat mounting base plate 1-2 is installed on the top of the frame body 1-1. A support pad 1-3 is installed at the center of the mounting base plate 1-2. The box 7 is installed on the support pad 1-3. By setting the support pad 1-3, the position of the box 7 can be raised, thereby shortening the distance between the box 7 and the inner cover 8 and improving the installation speed.

[0042] This invention discloses an automatic inner cap pressing device. The device features an ingenious structure and convenient operation. It comprises a press guide mechanism 2, a positioning mechanism 3, a clamping mechanism 4, and an inner cap feeding mechanism 5. The positioning mechanism 3 and clamping mechanism 4 contact and clamp the box body 7. The inner cap feeding component 5-1 in the inner cap feeding mechanism 5 pushes the inner cap 8, located at the bottom of the inner cap feeding bucket 5-1-9, upwards towards the box body 7. The press guide mechanism 2 then presses the inner cap 8 against the box body 8, ensuring a tight seal at the contact point between the inner cap 8 and the box body 7. This reduces the probability of liquid or gas leakage, guarantees the performance of the bottle or box, enhances the user experience, and facilitates the promotion and application of the aforementioned automatic inner cap pressing device in the market.
