Description

Technical Field

[0001] This utility model relates to the field of capping machine equipment technology, and in particular to a calibration mechanism for a filling and capping machine. Background Technology

[0002] Capping machines utilize a vacuum system to grip bottle caps. Above the end of the cap conveyor belt or wheel, there is a vacuum suction cup. When the bottle cap moves to the area below the vacuum suction cup, the vacuum suction cup moves downward and generates negative pressure, sucking up and lifting the bottle cap. Then, through a cylinder pressing downward or other conveying methods, the bottle cap is moved to a position directly above the bottle mouth, ready for capping. However, existing capping machines cannot guarantee the alignment of the bottle cap with the bottle mouth during the capping process due to their correction mechanism.

[0003] For example, Chinese utility model patent CN219507646U discloses a correction mechanism for a filling, capping, and screwing machine, which relates to the field of filling, capping, and screwing machine technology. The correction mechanism includes a main body. Although this correction mechanism can correct the position of the filling bottle, ensuring it is always directly below the screwing machine, which facilitates rapid screwing, the vacuum suction cup pushes the cap to rotate during a pressing process where the cap rotates and descends simultaneously. When the bottle is pressed, it rubs against the periphery of the conveying and positioning mechanism. Over time, this friction can cause wear on the conveying device. Even if the bottle is conveyed directly below the screwing machine, it will shift again during the pressure between the cap and the bottle neck, making it impossible to guarantee that the cap and bottle neck are on the same central axis. Therefore, a correction mechanism for a filling, capping, and screwing machine that can solve the above problems is proposed. Utility Model Content

[0004] To solve the technical problem of aligning the bottle cap with the bottle body during capping, this utility model provides a calibration mechanism for a filling and capping machine.

[0005] This utility model is achieved using the following technical solution: a calibration mechanism for a filling, capping, and sealing machine, comprising a capping machine docking plate, a threaded sleeve fixedly connected to one side of the capping machine docking plate, a plurality of metal springs rotatably connected to the lower side of the threaded sleeve, the plurality of metal springs being arranged in a circumferential array, a clamping block fixedly connected to the lower end of each metal spring, an annular push plate provided below the threaded sleeve, a vacuum suction cup provided on the annular push plate, a slot pushing mechanism provided between the vacuum suction cup and the annular push plate, a plurality of limiting slots provided on the annular push plate, the plurality of limiting slots being arranged in a circumferential array, the metal springs being paired with the limiting slots one by one, and the outer side of each metal spring being slidably connected to the inner side of the limiting slot, a capping mechanism provided on the upper side of the threaded sleeve, and a push plate limiting mechanism provided on the upper side of the annular push plate.

[0006] As a further improvement to the above solution, the slot pushing mechanism includes an annular slot opened on the outside of the vacuum suction cup, and the inner side of the annular pusher is rotatably connected to the inner side of the annular slot.

[0007] As a further improvement to the above solution, the screw cap mechanism includes a threaded rod that is threadedly engaged with the inside of the threaded sleeve. The lower end of the threaded rod is rotatably connected to the upper side of the vacuum suction cup. The threaded rod is provided with a threaded rod drive mechanism that causes the threaded rod to rise or fall.

[0008] As a further improvement to the above solution, the threaded rod drive mechanism includes a slot opened on the threaded rod, a rib slidably connected to the inner side of the slot, and a rib drive mechanism provided on the upper side of the threaded sleeve.

[0009] As a further improvement to the above solution, the joist drive mechanism includes a servo motor mounted on the upper side of the threaded sleeve, and the output end of the servo motor is fixedly connected to the upper end of the joist.

[0010] As a further improvement to the above solution, the push plate limiting mechanism includes multiple sliding grooves opened on the threaded sleeve. The multiple sliding grooves are distributed in a circumferential array. A sliding rod is slidably connected to the inner side of each sliding groove. The lower ends of the multiple sliding rods are simultaneously fixedly connected to the upper side of the annular push plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, the bottle cap is controlled to rotate and descend by a vacuum suction cup. During this process, the annular pusher is pushed down along with it. At this time, the limiting groove on the annular pusher, under the action of the structural features of the metal spring, enables multiple clamping blocks to position the bottle body at the same time, ensuring that the bottle body and the bottle cap controlled by the vacuum suction cup are on the same straight line, thereby improving the correction accuracy of the capping.

[0013] 2. This utility model uses a ring-shaped pusher to push multiple metal springs to open or close simultaneously, thereby positioning the clamping block on the bottle body. It has the advantages of simple structure, robust durability, and easy maintenance. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example:

[0021] Please combine Figures 1-3 This embodiment provides a calibration mechanism for a filling, capping, and corking machine, including a capping machine docking plate 1. A threaded sleeve 3 is fixedly connected to one side of the capping machine docking plate 1. In this embodiment, two metal springs 9 are rotatably connected to the lower side of the threaded sleeve 3. The metal springs 9 have excellent toughness and are arranged in a circumferential array. A clamping block 6 is fixedly connected to the lower end of each metal spring 9. The clamping surface of the clamping block 6 is provided with a structure adapted to the side profile of the bottle. An annular pusher 7 is provided below the threaded sleeve 3. The center of the annular pusher 7 has a hollow structure, and the annular pusher 7 is provided with... A vacuum suction cup 4 is provided. In this embodiment, the vacuum suction cup 4 is used to create an adsorption effect with the bottle cap. In other embodiments, the bottle cap can be rotated by friction. A slot pushing mechanism is provided between the vacuum suction cup 4 and the annular push plate 7. Two limiting slots 14 are provided on the annular push plate 7. The two limiting slots 14 are distributed in a circumferential array. Metal springs 9 are paired with the limiting slots 14 one by one, and the outer side of each metal spring 9 is slidably connected to the inner side of the limiting slot 14. A cap screwing mechanism is provided on the upper side of the threaded sleeve 3, and a push plate limiting mechanism is provided on the upper side of the annular push plate 7.

[0022] It should be noted that the structure of the metal fragment 9 is as follows: Figure 1 As shown, the metal spring 9 has an arc-shaped structure, and the bend of the arc-shaped structure is rounded and straightened. This way, when the rear clamping block 6 has already clamped the bottle and the annular pusher 7 continues to descend, the clamping block 6 will not continue to squeeze inward, thus achieving the effect of protecting the bottle structure.

[0023] Please combine Figure 3 As shown, the slot pushing mechanism includes an annular slot 13 opened on the outside of the vacuum suction cup 4, and the inner side of the annular pusher 7 is rotatably connected to the inner side of the annular slot 13.

[0024] With the above technical solution, when the vacuum suction cup 4 rotates and moves downward, the annular pusher 7 slides up and down in the vertical plane under the limiting action of the slide rod 8, while in the horizontal plane, the vacuum suction cup 4 rotates inside the vacuum suction cup 4, thereby achieving the effect of pushing the annular pusher 7 to descend.

[0025] Please combine Figure 3 As shown, the screw cap mechanism includes a threaded rod 5 that is threadedly connected to the inside of the threaded sleeve 3. The lower end of the threaded rod 5 is rotatably connected to the upper side of the vacuum suction cup 4. The threaded rod 5 is provided with a threaded rod drive mechanism that causes the threaded rod 5 to rise or fall. The threaded rod drive mechanism includes a slot 12 opened on the threaded rod 5. In this embodiment, the slot 12 has a triangular structure. A rib 11 is slidably connected to the inner side of the slot 12. The rib 11 is a triangular rib. The upper side of the threaded sleeve 3 is provided with a rib drive mechanism.

[0026] The above technical solution achieves the effect of driving the threaded rod 5 to rotate through the joist 11. Under the action of the threaded sleeve on the outside of the threaded rod 5, the joist 11 slides relative to the inside of the slot 12.

[0027] Please combine Figure 1 As shown, the joist drive mechanism includes a servo motor 2 mounted on the upper side of the threaded sleeve 3, and the output end of the servo motor 2 is fixedly connected to the upper end of the joist 11.

[0028] Please combine Figure 3 As shown, the push plate limiting mechanism includes two slide grooves 10 opened on the threaded sleeve 3. The slide grooves 10 are cylindrical spatial cavities. The two slide grooves 10 are arranged in a circumferential array. Each slide groove 10 has a slide rod 8 slidably connected to its inner side. The lower ends of the two slide rods 8 are simultaneously fixedly connected to the upper side of the annular push plate 7.

[0029] The implementation principle of the correction mechanism of the filling, capping and screwing machine in this application embodiment is as follows: When the bottle to be capped has moved directly below the vacuum suction cup 4, the bottle mouth has already been successfully placed in the previous capping process, and the cap that has not yet been rotated and locked has been placed on the upper side of the bottle mouth. At this time, the screwing machine detects that the bottle cap is ready and starts the servo motor 2, which drives the jack 11 to rotate. The jack 11 directly pushes the threaded rod 5 to rotate in the slot 12. Under the action of the threaded sleeve 3, the threaded rod 5 achieves a rotating and descending motion. The jack 11 slides upward relative to the slot 12, while the downward-moving threaded rod 5 pushes the annular pusher 7 and the vacuum suction cup 4 to move downward at the same time. Since the annular pusher 7 is limited by the sliding rod 8 on its upper side, the annular pusher 7... As the annular pusher 7 moves downward, the vacuum suction cup 4 rotates relative to it inside the annular pusher 7. When the annular pusher 7 moves downward to the first position, each metal spring 9 pushes the clamping block 6 to abut and position the bottle body. At the same time, the vacuum suction cup 4 reaches the top of the bottle cap and successfully creates a vacuum negative pressure to adsorb the bottle cap. The adsorbed bottle cap rotates with the vacuum suction cup 4 and begins to screw on. The bottle cap rotates and descends while spiraling. During the descent, the annular pusher 7 also descends together. However, due to the excellent toughness of the metal spring 9 and the transition arc stage in the structure of the metal spring 9, even if the annular pusher 7 descends, the clamping block 6 will not clamp the bottle body too forcefully.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
