Description

Technical Field

[0001] This invention relates to the field of capping machine equipment technology, and more specifically to an assembly of a quick-adjusting torque capping head. Background Technology

[0002] A capping machine, also known as a capping machine, sealing machine, or locking machine, is used to tighten and loosen the caps of plastic and glass bottles after they have been dispensed.

[0003] Capping heads are typically fixed to the capping head assembly via a push rod. The fixed size of the push rod makes it inconvenient to replace them with different sized capping heads. Changing capping heads is cumbersome and slow, impacting capping efficiency. In some existing capping heads with adjustable torque, the adjusting steel ring needs to be pressed down first to expose the internal sealing ring and other components before rotating to adjust the torque. This allows the filling liquid to seep into the capping head, affecting its sealing and aseptic performance, resulting in poor filling efficiency. Furthermore, adjusting the output torque requires tools, which is inconvenient for workers.

[0004] Because existing cap-grabbing devices cannot guarantee consistent cap-grabbing direction, problems such as misaligned caps and skewed caps may occur. This is mainly due to deviations in the conveyor path of the pressing mechanism. The pressing mechanism typically uses a lifting drive mechanism (such as a cam drive mechanism) to drive the cap-screwing gripper to rise and fall. The cap-screwing gripper is equipped with claws for gripping the cap, which are driven by corresponding drive cylinders. After the cap-screwing gripper descends, the drive cylinders on the claws drive the claws to grasp the cap, and then a rotation drive mechanism drives the entire cap-screwing gripper to rotate, thereby tightening the cap onto the container. With existing cap-screwing grippers, caps are prone to skew during gripping, leading to poor fit between the cap and container during operation of the pressing mechanism. In severe cases, this can even result in failure to cap properly or leakage and damage to the product. Furthermore, since the claw drive cylinders need to activate after the cap-screwing gripper has descended to a predetermined position, precise adjustment of the claw drive cylinder's stroke position is required.

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

[0016] (1) The present invention has a telescopic sleeve sealed at the upper end of the outer adjustment sleeve, and a top pressing device is passed through the upper end of the telescopic sleeve and sealed to it. The lower end of the top pressing device is connected to the cap gripping mechanism through a magnetic adjustment mechanism. When the capping operation is performed, it is ensured that only the claw part of the capping head contacts the bottle cap, and other parts are effectively sealed to prevent liquid from entering.

[0017] (2) The cap-grabbing mechanism of the present invention has an inner support sleeve sealed inside the outer adjusting sleeve. A magnetic adjustment mechanism is provided inside the inner support sleeve, and its lower end is adapted to connect with the cap-grabbing mechanism. The cap-grabbing mechanism includes a cap-grabbing bearing component, a rotating pull rod, a limiting steel ball, a cap-grabbing block, and a quick-change assembly. The lower end of the inner support sleeve is sealed to the cap-grabbing bearing component. A rotating pull rod is adapted to install in the middle of the cap-grabbing bearing component. A limiting steel ball is circumferentially movable on the rotating pull rod, and the limiting steel ball can contact the cap-grabbing block. The lower end of the cap-grabbing bearing component is sealed to the quick-change assembly. The cap-grabbing mechanism has a simple structure, can effectively seal with the inner support sleeve during use, and simultaneously achieves quick disassembly and quick assembly functions, effectively improving cap-grabbing efficiency.

[0018] (3) The magnetic adjustment mechanism of the present invention has the outer magnetic sheet and the inner magnetic sheet set relatively vertically, so that the output torque can be adjusted to be constant when rotating the entire set, reducing the vibration when gripping the cap. Rotating the outer adjustment sleeve makes the outer adjustment sleeve adjust along its internal thread line. At this time, the outer magnetic sheet and the outer adjustment sleeve rotate together, adjusting the area covered by the outer magnetic sheet and the inner magnetic sheet to adjust the magnitude of the magnetic force. The magnetic coupling between the outer magnetic sheet and the inner magnetic sheet is adjusted in time in the vertical direction. There is no need to expose the internal structural parts of the capping head, improving the overall sealing performance. The output torque can be adjusted by hand, which is simple and quick.

[0019] (4) The top pressing mechanism of the present invention is adapted to be connected to an external capping machine through a connector. A capping rod is inserted into the center of the connector. The lower end of the capping rod is elastically connected to the lower pressing rod through a bearing. A spring-loaded mechanism is fitted and sealed on the outer periphery of the lower pressing rod. The top pressing mechanism can be easily installed into the capping machine as a whole and is easy to replace as a whole. The spring-loaded mechanism provides double-ear positioning for the lower pressing rod, making the perpendicularity of the lower pressing rod and the capping rod to the claw of the cap gripper head higher during use, and the positioning of the bottle cap is more accurate. After the claw of the cap gripper head contacts the bottle cap, it can promptly straighten the bottle cap that is shaking and reduce the swing during capping, and accurately press the bottle cap into the bottle mouth in one go for sealing without adjusting the claw drive cylinder.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 11 As shown, an assembly of a quick-adjusting torque capping head includes a telescopic sleeve 1, an outer adjusting sleeve 2, an inner support sleeve 3, a magnetic adjustment mechanism 4, a cap gripping mechanism 5, a rotating pull rod 6, a limiting steel ball 7, a cap gripping block 8, a quick-change component 9, an outer magnet outer sleeve 10, an outer magnet inner sleeve 11, an inner magnet sleeve 12, a rotating shaft 13, an outer magnetic plate 14, an inner magnetic plate 15, a bearing mounting ring 16, a capping bearing 17, a bearing mounting component 18, a bearing washer ring 19, a quick-change pressure ring 20, and a spring top block 21. Quick-change spring 22, rubber gasket ring 23, lower sealing ring 24, connector 25, pressure plate rod 26, lower pressure rod 27, motion shaft 28, spring guide sleeve 29, spring key 30, spring guide seat 31, spring pull block 32, spring top ring 33, upper guide sleeve 34, first spring 35, second spring 36, third spring 37, lower guide sleeve 38, flat bearing 39, bearing mounting seat 40, limit ring 41, waterproof gasket 42, sealing ring 43, wrench position 44, ball bearing 45.

[0033] In the description of this invention, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the 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, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] like Figures 1 to 11 As shown, the upper end of the outer adjustment sleeve 2 is sealed with a telescopic sleeve 1, and the upper end of the telescopic sleeve 1 is fitted with a top pressing device and sealed to it. When the cap is being gripped, it is ensured that only the claw part of the cap gripping head contacts the bottle cap, and other parts are effectively sealed to prevent liquid from entering.

[0036] The lower end of the pressing device is connected to the cover gripping mechanism 5 via a magnetic adjustment mechanism 4. Specifically, the magnetic adjustment mechanism 4 includes an outer magnet sleeve 10, an outer magnet inner sleeve 11, an inner magnet sleeve 12, a rotating shaft 13, an inner magnetic sheet 15, and an outer magnetic sheet 14. The upper inner side of the inner support sleeve 3 is sequentially spaced with the outer magnet sleeve 10, the outer magnet inner sleeve 11, the inner magnet sleeve 12, and the rotating shaft 13. The inner support sleeve 3 is fixedly connected to the outer magnet sleeve 10. An even number of outer magnetic sheets 14 are arranged vertically in the gap between the outer magnet sleeve 10 and the outer magnet inner sleeve 11, and an even number of inner magnetic sheets 15 are arranged vertically in the gap between the inner magnet sleeve 12 and the rotating shaft 13. The upper end of the cover gripping bearing is connected to the lower end of the rotating shaft 13. The outer magnetic plate 14 and the inner magnetic plate 15 are both set relatively vertically, so that the output torque that can be adjusted when rotating the outer adjusting sleeve 2 is constant, reducing the vibration when gripping the cap. Rotating the outer adjusting sleeve 2 causes the outer adjusting sleeve 2 to be adjusted along its internal thread. At this time, the outer magnetic plate 14 and the outer adjusting sleeve 2 rotate together, adjusting the area covered by the outer magnetic plate 14 and the inner magnetic plate 15, thereby adjusting the magnitude of the magnetic force. The magnetic coupling between the outer magnetic plate 13 and the inner magnetic plate 15 is adjusted in the vertical direction in a timely manner. There is no need to expose the internal structural parts of the capping head, improving the overall sealing performance. The output torque can be adjusted by hand, which is simple and quick.

[0037] Specifically, the cover gripping mechanism 5 includes a cover gripping bearing, a rotating pull rod 6, a limiting steel ball 7, a cover gripping block 8, and a quick-change assembly 9. The lower end of the inner support sleeve 3 is sealed to the cover gripping bearing. A ball bearing 45 is provided between the upper end of the inner support sleeve 3 and the inner wall of the outer adjustment sleeve 2. When the outer adjustment sleeve 2 is rotated, the ball bearing 45 will move along the internal thread line of the inner wall of the outer adjustment sleeve 2 to indicate the adjustment angle. The outer surface of the outer adjustment sleeve 2 is provided with a magnetic adjustment scale, which is not shown in this figure.

[0038] A rotating pull rod 6 is fitted in the middle of the gripper cover bearing component. A limiting steel ball 7 is circumferentially movable on the rotating pull rod 6, and the limiting steel ball 7 can contact and connect with the gripper cover locking block 8, used to quickly assemble and disassemble the claw part of the gripper cover head in conjunction with the rotating pull rod 6. The lower end of the gripper cover bearing component is sealed to the quick-change assembly 9. Specifically, the quick-change assembly 9 includes a quick-change pressure ring 20, a spring top block 21, and a quick-change spring 22. The lower end of the bearing mounting ring 16 is sealed to the quick-change pressure ring 20. The quick-change spring 22 is located inside the quick-change pressure ring 20. The upper end of the quick-change spring 22 is connected to the gripper cover locking block 8, and the lower end of the quick-change spring 22 is fitted to the spring top block 21. The spring top block 21 is attached to the outer wall of the rotating pull rod 6. Rubber gasket rings 23 are provided at the connection points between the inner support sleeve 3 and the outer adjusting sleeve 2 and the bearing mounting ring 16, respectively. A lower sealing ring 24 is provided at the connection point between the bearing mounting ring 16 and the quick-change pressure ring 20. When it is necessary to disassemble or install the claw of the cover gripper, manually pull the spring top block 21 downward or downward, and the rotating pull rod 6 will simultaneously move downward or downward. The limiting steel ball 7 on the rotating pull rod 6 will expand out from the cover gripper block 8, allowing for quick disassembly and assembly of the claw for gripping the cover installed inside the rotating pull rod 6.

[0039] The top-pressing device includes a connector 25, a capping rod 26, a lowering rod 27, and a spring-loaded mechanism. The upper end of the telescopic sleeve 1 is sealed to the connector 25. The capping rod 26 is inserted into the center of the connector 25. The lower end of the capping rod 26 is elastically connected to the lowering rod 27 through a top-pressing bearing. The outer periphery of the lowering rod 27 is fitted with a spring-loaded mechanism. The spring-loaded mechanism enables the lowering rod 27 to be positioned with double ears, making the perpendicularity of the lowering rod 27 and the capping rod 26 to the claw of the cap-grabbing head higher during use, resulting in more accurate positioning of the bottle cap. After the claw of the cap-grabbing head contacts the bottle cap, it can promptly straighten any wobbling bottle cap and reduce the swing during capping, accurately pressing the bottle cap into the bottle mouth in one go for sealing, without the need to adjust the claw drive cylinder.

[0040] Specifically, the rebound mechanism includes a motion shaft 28, a rebound guide sleeve 29, a rebound key 30, a rebound guide seat 31, a rebound pull block 32, a spring top ring 33, an upper guide sleeve 34, a first spring 35, a second spring 36, a third spring 37, and a lower guide sleeve 38. The lower end of the connector 25 is sealed and fixedly mounted with the motion shaft 28. The outer side of the lower end of the motion shaft 28 is fitted with the rebound guide sleeve 29, and the lower end of the rebound guide sleeve 29 contacts the rebound key 30. The two rebound keys 30 are fitted opposite each other on the lower part of the motion shaft 28. The outer side of the rebound key 30 is fitted with the rebound guide seat 31, and the lower end of the rebound guide seat 31 is fixedly mounted with the rebound pull block 32. The upper end of the rebound guide seat 31 is provided with a spring top ring 33, and the spring top ring 33 is provided with an adjusting screw (not shown in this figure, but a common adjusting screw on the market), which can be used to adjust the pressure.

[0041] A first spring 35 is sandwiched between the spring top ring 33 and the outer periphery of the motion shaft 28. The first spring 35 can effectively buffer the pressure between the spring top ring 33 and the motion shaft 28, and maintain the coaxiality between the rebound guide seat 31, the motion shaft 28 and the spring top ring 33.

[0042] An upper guide sleeve 34 is fixed inside the motion shaft 28. A lower pressure rod 27 passes through the upper guide sleeve 34. A second spring 36 is sleeved on the upper outer circumference of the lower pressure rod 27, and a third spring 37 is sleeved on the lower part of the lower pressure rod 27. The second spring 36 and the third spring 37 do not contact each other. A lower guide sleeve 38 is provided at the upper end of the rotating pull rod 6 and is attached to the lower outer wall of the lower pressure rod 27. The upper guide sleeve 34 and the lower guide sleeve 38 help maintain the coaxiality of the overall device, making the positioning of the cap gripping or capping more accurate. The third spring 37 is used to ensure that the rebound path of the lower pressure rod 27 after extension is consistent with the initial extension state, maintaining the verticality and positioning of the capping action. The wire diameter and inner diameter of the first spring 35, the second spring 36, and the third spring 37 decrease sequentially and are coaxially arranged, which evenly distributes and reduces the force of vibration rebound during the capping process.

[0043] The cover bearing assembly includes a bearing mounting ring 16, a cap bearing 17, a bearing mounting component 18, and a bearing washer ring 19. The lower end of the inner support sleeve 3 is fixedly connected to the bearing mounting ring 16. The cap bearing 17 is provided inside the bearing mounting ring 16. A rotating pull rod 6 is rotatably connected to the middle of the cap bearing 17. The upper and lower ends of the cap bearing 17 are respectively attached to the bearing mounting component 18 and the bearing washer ring 19. The upper end of the bearing mounting component 18 is connected to the lower end of the rotating shaft 13, and the lower end of the bearing washer ring 19 is attached to the inside of the bearing mounting ring 16. The lower end of the bearing mounting ring 16 is sealed to the quick-change assembly 9.

[0044] The top pressure bearing component includes a flat bearing 39 and a bearing mounting seat 40. The upper end of the lower pressure rod 27 is fitted with the bearing mounting seat 40, and the flat bearing 39 is adapted to be installed in the bearing mounting seat 40. The flat bearing 39 is adapted to be connected to the lower end of the pressure cover rod 26. A gap is left between the outer wall of the bearing mounting seat 40 and the inner wall of the connector 25 to facilitate the up and down movement of the pressure cover rod 26.

[0045] The bearing mounting base 40 has a limiting boss in the middle, and the upper end of the second spring 36 is abutted on the limiting boss. The lower end of the second spring 36 is abutted on the inner side of the motion shaft 28.

[0046] The lower pressure rod 27 is provided with a limiting ring 41, the upper guide sleeve 34 abuts against the upper end face of the limiting ring 41, the upper end of the third spring 37 abuts against the lower end face of the limiting ring 41, and the lower end of the third spring 37 abuts against the inner side of the rebound pull block 32.

[0047] A waterproof pad 42 is provided at the connection between the spring pull block 32 and the spring guide seat 31; the upper end of the motion shaft 28 is provided with an installation groove, and a sealing ring 43 is provided in the installation groove. The sealing ring 43 covers the outer wall of the connector 25 to ensure the sealing of the top pressure device during use and facilitate subsequent cleaning.

[0048] The upper guide sleeve 34 is made of PEK, a ketone-based, semi-crystalline, high-performance engineering thermoplastic. Due to its high thermal dimensional stability, low flammability, excellent chemical resistance, and superior mechanical properties over a wide temperature range, it is commonly used in demanding applications across various markets. Because PEK retains its strength even at elevated temperatures, it is typically used in applications with vibration or cyclic loading conditions, and in applications where components must withstand high mechanical loads at high temperatures for extended periods, such as gears, shafts, bushings, bearings, and rotating precision parts in the micro aerospace and automotive industries.

[0049] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any modifications, equivalent changes, improvements, etc., made in accordance with the claims of the present invention shall still fall within the scope of the present invention.
