Description

Technical Field

[0001] This application relates to the field of packaging machinery technology, and in particular to a linear capping machine suitable for bottle caps of different sizes. Background Technology

[0002] Inline capping machines are automated equipment in the packaging machinery field. Through a unique linear conveyor structure, bottles and caps enter the capping station sequentially and orderly. During production, it automatically grasps the caps and precisely tightens them onto the bottles according to a preset torque. This significantly improves packaging efficiency, replaces manual capping, enables continuous, high-speed operation, and reduces labor costs. Simultaneously, with stable capping torque control, it ensures consistent tightening of each cap, improving packaging quality, ensuring good product sealing, and reducing product leakage and spoilage caused by improper capping. Widely used in packaging production lines in the food, pharmaceutical, and daily chemical industries, it is a key piece of equipment for achieving automated packaging processes.

[0003] In the operation of the inline capping machine, the bottle is fed into the equipment in a straight line by a conveyor and precisely positioned by a positioning mechanism. Simultaneously, bottle caps are arranged and conveyed to the capping station via a cap feeding system. Then, the capping head, driven by a transmission mechanism, descends to grab the bottle cap and tightens it onto the bottle through rotation. During this process, a torque control system monitors and adjusts the capping force in real time to ensure a tight cap without damaging the cap or bottle. The tightened bottle is then conveyed out, completing the entire capping process.

[0004] However, some existing inline capping machines cannot adapt to different cap sizes. When faced with changes in parameters such as cap diameter, height, and thread specifications, they are difficult to adjust quickly and effectively, leading to jamming, accumulation, or misalignment of non-standard caps during transport. This low adaptability to cap size variations not only limits the equipment's versatility in packaging diverse products, forcing companies to equip multiple dedicated machines for different product specifications, increasing equipment procurement and maintenance costs, but also seriously affects production efficiency. Frequent changes in product specifications require significant time for equipment debugging and modification, making it difficult to meet the flexible production needs of the modern packaging industry for small batches and multiple varieties. Therefore, this paper proposes an inline capping machine suitable for caps of different sizes to solve the above problems. Utility Model Content

[0008] Preferably, the connecting mechanism includes a plurality of support columns, the top ends of the plurality of support columns are fixedly connected to the bottom end of the movable block, support rings are fixedly connected to the outer sides of the bottom ends of the plurality of support columns, movable rings are slidably connected to the outer sides of the plurality of support columns, a plurality of fixing blocks are fixedly connected to the inner walls of the bottom ends of the plurality of support columns, a plurality of limiting balls are fixedly connected to the inner walls of the bottom ends of the plurality of support columns, a retractable column is fixedly connected to the top end of the plurality of fixing blocks, a spring is sleeved on the outer side of each of the plurality of retractable columns, a guide block is fixedly connected to the inner walls of the plurality of support columns, and a connecting column is fixedly connected to the bottom end of each of the plurality of guide blocks.

[0009] By adopting the above technical solution, the connecting mechanism is connected to the moving block through the support column to achieve overall installation. The support ring, moving ring and limiting ball cooperate to limit the range of sliding of the moving ring along the support column. The fixed block, shrink column and spring form an elastic structure to give the mechanism buffering ability. At the same time, the guide block and connecting column assist in guiding, ensuring that the connecting mechanism can flexibly change different sized gripping tools when cooperating with capping operations.

[0010] Preferably, the fixing component includes a nut one, the bottom end of the nut one is fixedly connected to the top end of the fixing plate two, the inner wall of the nut one is threadedly connected to a pressure plate, the inner thread of the fixing plate one is threadedly connected to a nut, and the bottom end of the nut is threadedly connected to the nut two.

[0011] By adopting the above technical solution, in the fixing component, nut one is fixed on fixing plate two and is threaded with the lower pressure plate. The lower pressure plate can be rotated to press or loosen the lower component. Nut is threaded to fixing plate one and, together with nut two, can tighten and adjust the relevant components from another angle. The two work together to adjust the position of the adjustment mechanism to adapt to bottle caps of different sizes.

[0012] Preferably, two transmission arc rods are fixedly connected to the left side of the load-bearing plate, and the front side of the baffle is fixedly connected to the rear side of the two support plates;

[0013] By adopting the above technical solution, the transmission arc rod on the left side of the load-bearing plate provides a guiding path for the bottle cap transmission, helping the bottle caps to leave the cap sorting bin in an orderly manner and enter the next process. The baffle and the support plate are connected to each other to form a stable frame structure, which enhances the overall rigidity and stability of the adjustment mechanism and ensures that the positions of each component in the cap sorting bin and during the adjustment process are fixed.

[0014] Preferably, the top end of the lower pressure plate is externally threaded to the inner wall of the second fixed plate, the external thread of the nut is externally threaded to the inner wall of the load-bearing plate, and the top end of the second nut is fixedly connected to the bottom end of the load-bearing plate.

[0015] By adopting the above technical solution, the lower pressure plate and the second fixed plate are connected by threads, and their upper and lower positions can be adjusted by rotation, thereby pressing or loosening the lower components; the nut passes through the load-bearing plate and is connected to it by threads, and together with the second nut at the bottom, the load-bearing plate and related components can be fastened from the upper and lower ends, ensuring the stability of the adjustment mechanism and the reliability of the component connection, and realizing the effective fixing and flexible adjustment of structures such as the cover and silo.

[0016] Preferably, each of the connecting posts has a slot at its outer top, and the adjacent sides of the limiting spheres are fixedly connected to the outer top of the connecting posts.

[0017] By adopting the above technical solution, the slot opened at the top of the connecting column can provide positioning and installation interfaces for other components, making it easy to achieve interlocking connection between components; the limiting ball is fixed at the top of the connecting column, which can not only limit the sliding stroke of components such as the moving ring and prevent them from deviating from the normal operating trajectory, but also help enhance the overall stability of the connecting mechanism through cooperation with the slot and other structures.

[0018] Preferably, the top ends of the plurality of contraction columns are fixedly connected to the inner wall of the bottom end of the support column, and the bottom ends of the plurality of springs are respectively fixedly connected to the top ends of the plurality of fixing blocks;

[0019] By adopting the above technical solution, the top of the shrink column is fixed to the inner wall of the bottom of the support column, forming an elastic reset structure with the fixing block and the spring. The bottom of the spring is connected to the fixing block. When the connecting mechanism is under force, the spring can be compressed and deformed. Guided by the shrink column, it can provide appropriate contact pressure and prevent damage to the bottle cap or equipment parts due to rigid collision.

[0020] Preferably, the bottom end of the movable ring is fixedly connected to the top end of the support ring, and the opposite sides of the plurality of fixed blocks are fixedly connected to the inner wall of the movable ring.

[0021] By adopting the above technical solution, the moving ring and the support ring are fixedly connected to form a linkage structure. The fixed block is connected to the inner wall of the moving ring and can slide along the support column with the moving ring. This structural design allows the fixed block to move synchronously during the up-and-down movement of the moving ring, and together with the retraction column, spring and other components, adjusts the reset performance of the connecting mechanism.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this utility model, the threaded structure of the nut and the lower pressure plate drives the lower pressure plate to move up and down. The lower pressure plate adjusts its height to adapt to bottle caps of different heights. The support plate drives the baffle to adjust its position in the horizontal direction. The cooperation of the nut and the nut adjusts the position of the baffle to adapt to bottle caps of different diameters, thereby realizing the adaptation to bottle caps of different diameters and heights and improving the processing capacity of the inline capping machine for diverse bottle caps.

[0024] 2. In this utility model, by sliding the moving ring, the movement of the moving ring drives the connecting column to compress the spring, and the slot is released from the constraint of the limiting ball, so that the old gripper can be quickly pulled out; after the new gripper is inserted, the spring rebounds and drives the fixing block to reset, and the limiting ball is re-engaged into the slot to complete the fixation, thereby realizing the convenient replacement of different specifications of capping grippers, significantly improving the flexibility and maintenance efficiency of the inline capping machine in dealing with multiple sizes of bottle caps.

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0031] Example: A linear capping machine suitable for bottle caps of different sizes, refer to Figure 2 and Figure 3 The system includes a connecting plate 1, with multiple supports 2 fixedly connected to its bottom end. These supports evenly distribute the weight of the connecting plate 1 onto the operating platform 5, preventing excessive localized stress. Multiple supports 3 are fixedly connected to the top end of the connecting plate 1, providing a stable mounting base for the capping bin 4. These supports are precisely welded to the connecting plate 1, ensuring the capping bin 4 remains stable during operation. The top ends of the supports 3 are fixedly connected to the capping bin 4, and the bottom ends of the supports 2 are fixedly connected to the operating platform 5. This provides a stable support platform for the entire capping machine. Simultaneously, the operating platform 5 also provides space for equipment inspection and maintenance, facilitating routine maintenance and troubleshooting by staff, thus improving the equipment's practicality and maintainability.

[0032] Specifically, the connecting plate 1 serves as the core load-bearing component. Its bottom bracket 2 provides stable support for the inline capping machine, fixing the equipment onto the operating table 5. The top bracket 3 extends upwards, firmly supporting the cap sorting bin 4. This ensures sufficient space for the cap sorting bin 4 to sort bottle caps, while also ensuring the stability of the equipment operating above the operating table 5, thus achieving reliable construction and functional layering of the overall equipment structure.

[0033] An adjustment mechanism 6 is fixedly connected to the front external side of the cap sorting compartment 4. Through the threaded engagement of the nut and pressure plate in the fixing component 66, and the nut 663 and nut, the position and angle of the baffle 65 can be adjusted. This allows for flexible adjustment of the channel size and shape at the inlet of the cap sorting compartment 4 according to the shape, diameter, and height of different sized bottle caps. A sliding compartment 7 is fixedly connected to the bottom end of the connecting plate 1, providing a stable sliding track for the moving block 8. The high-precision machining of the sliding track ensures the smoothness and straightness of the moving block 8 during sliding. Guide grooves and limiting devices on the inner wall of the sliding compartment 7 limit the sliding range of the moving block 8, preventing it from shifting or derailing during sliding. The moving block 8 is slidably connected to the inner wall of the sliding compartment 7. Under the action of an external driving device such as a cylinder or motor, the moving block 8 slides linearly along the sliding track of the sliding compartment 7. Multiple connecting mechanisms 9 are fixedly connected to the bottom end of the moving block 8, allowing for quick and convenient replacement of the capping gripper.

[0034] Specifically, the adjusting mechanism 6 is fixed to the front of the cap sorting chamber 4, and can adjust the sorting path and position of the bottle caps in the chamber 4 to accommodate bottle caps of different sizes. The sliding chamber 7 and the moving block 8 form a sliding structure. The moving block 8 slides along the inner wall of the sliding chamber 7, driving the bottom connecting mechanism 9 to adjust its position. The two work together, with the adjusting mechanism 6 optimizing the bottle cap sorting process and ensuring the capping machine's ability to handle bottle caps of various sizes.

[0035] The adjustment mechanism 6 includes a load-bearing plate 61, which serves as the basic load-bearing component of the adjustment mechanism 6. It bears the weight from components such as the upper fixed plate, support plate 63, baffle 65, and fixing assembly 66. The rear side of the load-bearing plate 61 is fixedly connected to the front side of the cover compartment 4, ensuring the reliability and stability of the connection between the adjustment mechanism 6 and the cover compartment 4. Two fixed plates 62 are fixedly connected to the top of the load-bearing plate 61, serving as mounting carriers for the support plate 63 and fixing assembly 66, providing vertical support and fixing points for subsequent components. The support plate 63 is fixedly connected to the rear side of the fixed plate 62. When the fixing assembly 66 is adjusted, the support plate 63 can drive the baffle 65 to adjust its horizontal position. A second fixed plate 64 is fixedly connected to the top of the support plate 63. When the fixing assembly 66 is adjusted, the second fixed plate 64 moves with the rise and fall of the lower pressure plate 662. The baffle 65 is fixedly connected to the top of the load-bearing plate 61. When the adjustment mechanism 6 is adjusted, the position and angle of the baffle 65 change. The top of the fixed plate 64 is fixedly connected to the fixed component 66, which is raised and lowered by the threaded engagement of the nut 661 with the lower pressure plate 662.

[0036] Specifically, the load-bearing plate 61 serves as the basic support for the adjustment mechanism 6. It forms a stable frame through the fixed plate 62, the support plate 63, and the fixed plate 64, providing an installation carrier for the baffle 65 and the fixing component 66. The fixing component 66 adjusts its own structure to drive the fixed plate 64 to work in conjunction with the support plate 63, thereby adjusting the position and angle of the baffle 65. This effectively adjusts the bottle cap sorting path at the entrance of the cap sorting compartment 4 to meet the sorting needs of bottle caps of different sizes.

[0037] Reference Figure 2 and Figure 4 The connecting mechanism 9 includes multiple support columns 91, which transmit the movement of the movable block 8 to the components below, and provide installation and movement guidance for the movable ring 93, fixed block 97, etc. The top ends of the multiple support columns 91 are fixedly connected to the bottom ends of the movable block 8. The sliding of the movable block 8 within the slide chamber 7 causes the support columns 91 to move synchronously, transmitting the horizontal movement imparted by the slide chamber 7 to the connecting mechanism 9. Support rings 92 are fixedly connected to the outer bottom ends of the multiple support columns 91 respectively. When the movable ring 93 slides up and down, the support rings 92 act as a stop and positioner, ensuring that the movable ring 93 does not detach from the support column 91. Movable rings 93 are slidably connected to the outer sides of the multiple support columns 91 respectively, allowing the movable rings 93 to slide up and down along the support columns 91 under external force. Multiple fixed blocks 97 are fixedly connected to the inner walls of the bottom ends of the multiple support columns 91. When the movable ring 93 slides, the fixed blocks 97 move accordingly, driving the spring 95 and the retraction column 94 to work.

[0038] Specifically, the top of the support column 91 is connected to the movable block 8 and slides in the slide chamber 7 along with the movable block 8, providing a moving base for the connecting mechanism 9; the support ring 92 is fixed to the bottom of the support column 91 and cooperates with the slidingly connected movable ring 93, so that the movable ring 93 can slide up and down along the support column 91; while the fixed block 97 is fixed to the inner wall of the bottom end of the support column 91, which can limit the downward stroke of the movable ring 93 and ensure that it can adapt to the gripping and tightening operation of bottle caps of different sizes.

[0039] Multiple support columns 91 are fixedly connected to multiple limiting balls 96 on their bottom inner walls. When the connecting column 98 moves downward under the action of external force, the limiting balls 96 cooperate with the slots opened at the top of the connecting column 98 to fix the position of the connecting column 98. Multiple fixing blocks 97 are fixedly connected to the top of their tops with retractable columns 94. When the moving ring 93 drives the fixing blocks 97 to move up and down, the retractable columns 94 slide along the guide groove in the support column 91 to provide extension and retraction guidance for the spring 95, ensuring that the spring 95 maintains linear motion during compression and rebound. The spring 95 is sleeved on the outside of the multiple retractable columns 94. Multiple support columns 91 are fixedly connected to guide blocks 99 on their inner walls. Through the unique shape of the guide blocks 99, the connecting column 98 can be quickly fixed to the limiting balls 96 during replacement. Multiple guide blocks 99 are fixedly connected to the bottom of their bottoms with the connecting column 98. The operator can quickly disassemble and install a new cap gripper by separating the slot from the limiting balls 96.

[0040] Specifically, the spring 95 is sleeved on the outside of the shrink column 94 and cooperates with the fixing block 97 and the limiting ball 96. When the spring 95 is compressed, it causes the shrink column 94 to shrink. The limiting ball 96 restricts the movement range of the connecting column 98. The guide block 99 is connected to the connecting column 98 to provide guidance for the movement of the connecting column 98, ensuring its accurate replacement and realizing adaptive gripping and stable capping of bottle caps of different sizes.

[0041] Reference Figure 1 and Figure 2 The fixing component 66 includes a nut 661, which serves as a mounting base for the lower pressure plate 662, providing a stable threaded connection foundation for the lower pressure plate 662. The bottom end of the nut 661 is fixedly connected to the top end of the fixing plate 64, forming a connection between the nut 661 and the fixing plate 64, making the nut 661 an extension of the fixing plate 64. The lower pressure plate 662 is threadedly connected to the inner wall of the nut 661. Utilizing the principle of threaded transmission, rotating the lower pressure plate 662 changes its vertical position within the nut 661. A nut 663 is threadedly connected to the inside of the fixing plate 62. Rotating the nut 663 changes its relative position within the fixing plate 62. The rotation of nut 663 will cause nut 664 to move horizontally outside the load-bearing plate 61. Nut 664 is connected to the bottom thread of nut 663. By tightening nut 664, nut 663 is fixed in the required position to prevent nut 663 from loosening due to vibration or other factors during equipment operation.

[0042] Specifically, the threaded engagement between nut 661 and the lower pressure plate 662 allows the rotating lower pressure plate 662 to move itself up and down, thus adapting to the height of different bottle caps; the threaded adjustment between nut 663 and nut 664 can change the relative position of the fixing plate 62 and the load-bearing plate 61, realizing flexible adjustment of the inlet channel size of the cap chamber 4 to adapt to different bottle cap specifications.

[0043] Two transmission arc rods 10 are fixedly connected to the left side of the load-bearing plate 61, which can effectively regulate the transmission path of bottle caps, reduce jamming and accumulation of bottle caps during transmission, and improve the efficiency and stability of bottle cap conveying. The front side of the baffle 65 is fixedly connected to the rear side of the two support plates 63. When the support plates 63 move under the action of the fixing component 66, the baffle 65 will move synchronously, thereby changing the size of the channel. The top of the pressure plate 662 is externally threaded to the inner wall of the second fixing plate 64. The operator can finely adjust the position of the pressure plate 662 by rotating it according to the actual height of the bottle cap, so that the channel height matches the height of the bottle cap. The external thread of the nut 663 is connected to the inner wall of the load-bearing plate 61, and the top of the nut 664 is fixedly connected to the bottom of the load-bearing plate 61, fixing the nut 663 to the load-bearing plate 61, preventing the nut 663 from loosening due to vibration during equipment operation, and ensuring the stability of the position of the first fixing plate 62.

[0044] Specifically, the transmission arc rod 10 and the baffle 65 form a bottle cap conveying channel. By adjusting the fixing component 66, the width and height of the channel can be changed, thereby accurately adapting to the conveying and sorting of bottle caps of different sizes, ensuring that bottle caps can enter the cap sorting bin 4 in an orderly manner, and improving the processing efficiency and adaptability of the inline capping machine for diverse bottle caps.

[0045] Each of the outer tops of multiple connecting posts 98 has a slot, which cooperates with the limiting ball 96 to restrict the movement range of the connecting post 98. The adjacent sides of the multiple limiting balls 96 are fixedly connected to the outer tops of the connecting post 98. These limit components, working in conjunction with the slots, provide precise limiting during the movement of the connecting post 98. The tops of multiple retractable posts 94 are fixedly connected to the inner wall of the bottom end of the support post 91. When the moving ring 93 drives the fixed block 97 to move up and down, the retractable posts 94 slide along the guide groove within the support post 91, providing guiding support for the extension and retraction of the spring 95. The bottoms of the multiple springs 95 are respectively fixedly connected to the tops of the multiple fixed blocks 97. The elasticity of the springs 95 can drive the fixed blocks 97 to return to their original position. The bottom of the moving ring 93 is fixedly connected to the top of the support ring 92. When the moving ring 93 is subjected to force, the spring 95 compresses and drives the fixed block 97. Multiple fixed blocks 97 are fixedly connected to the inner wall of the moving ring 93 on opposite sides. The fixed blocks 97 transmit the movement of the moving ring 93 to the spring 95, so that the spring 95 can be compressed or rebounded according to the actual situation.

[0046] Specifically, when the moving ring 93 slides along the support column 91, the contraction column 94 provides guidance, and the limiting ball 96 cooperates with the slot to limit the maximum stroke of the connecting column 98; the moving ring 93 is fixedly connected to the support ring 92, which has the effect of limiting and fixing, so that the connecting column 98 can be easily replaced to adapt to different sizes of bottle caps, and provides stable pressure during the gripping and capping process, ensuring the reliability and flexibility of the capping operation.

[0047] The implementation principle of this application embodiment is as follows: When adjustment is required according to the bottle cap size, the nut 661 is fixed to the fixing plate 64. By rotating the lower pressure plate 662, the lower pressure plate 662 is driven to move up and down along the inner wall of the fixing plate 64 under the threaded transmission to adapt to bottle caps of different heights. The nut 663 is threadedly connected to the load-bearing plate 61. When the nut 664 is rotated, the nut 663 is driven to move parallel to the inner wall of the load-bearing plate 61, thereby driving the fixing plate 62 connected to it to move. When the fixing plate 62 moves, it drives the support plate 63 to move through the fixed connection with the support plate 63. The front side of the baffle 65 is fixed to the rear side of the two support plates 63, so that the support plate 63 drives the baffle 65 to move. By changing the position of the baffle 65, the purpose of adapting to bottle caps of different sizes can be achieved. Therefore, during the cap sorting process, the position of the baffle 65 can be flexibly adjusted according to the specifications of different cap sizes, effectively controlling the movement trajectory and arrangement of the caps, improving the efficiency and accuracy of cap sorting, and enabling the inline capping machine to better adapt to various cap sizes, thus enhancing the versatility and practicality of the equipment.

[0048] When the gripper needs to be replaced, external force is applied to slide the moving ring 93 upward, releasing the engagement of the limiting ball 96 with the slot of the connecting post 98, allowing the gripper to be easily removed. This completes the operation of replacing the gripper driven by the connecting post 98. When fixing is required, the operation is reversed. The limiting ball 96 fixes the gripper in the slot at the top of the connecting post 98. Thus, when changing grippers to fit different sizes of bottle caps, operators do not need to use complicated tools. They can complete the gripper replacement through simple manual operation, greatly shortening the equipment adjustment time, improving work efficiency, reducing the risk of component damage due to frequent disassembly, and enhancing the flexibility and reliability of the equipment.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
