Description

Technical Field

[0001] This utility model relates to a clamping device, specifically, to an adjustable capping head clamping device for a filling machine. Background Technology

[0002] A filling machine is an automated or semi-automated mechanical device whose main function is to accurately, efficiently, and hygienically inject a specific amount of material into a packaging container. A capping machine is a type of filling machine that primarily screws caps onto the top of the bottle. During operation, the capping machine typically uses a clamping device to hold and fix the cap, then moves the clamping device and cap to the top of the bottle. The capping machine then moves the cap downwards until it contacts the top of the bottle. At this point, the capping machine rotates the clamping device and cap to tighten them onto the top of the bottle, completing the capping process. However, existing clamping devices... With the block size remaining constant, when clamping caps of different thicknesses is required, such as thicker caps, the clamping device only clamps the top of the cap, making it difficult to clamp the part of the cap far from the clamping device. Because the force on the part of the cap far from the clamping device is smaller, it is easy for it to shift during the cap tightening process, affecting the subsequent tightening effect of the cap. Therefore, it is necessary to stop the capping machine and make the operator spend a long time replacing the clamping device, which leads to a decrease in the overall capping efficiency of the capping machine. In view of this, we propose an adjustable capping head clamping device for filling machines. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable capping head clamping device for filling machines, so as to solve the problem mentioned in the background art that the clamping device is difficult to clamp bottle caps of different thicknesses and requires replacement of the clamping device, which leads to a decrease in capping efficiency.

[0004] To address the aforementioned problems, the present invention aims to provide an adjustable capping head clamping device for a filling machine, comprising a mounting plate with two symmetrically symmetrically arranged mounting slots penetrating the mounting plate. Two adjusting mechanisms are symmetrically arranged on the mounting plate, and a driving mechanism is provided inside the mounting plate. The driving mechanism drives the two adjusting mechanisms to move towards or away from each other, clamping and fixing them during the movement towards each other. Each adjusting mechanism includes an I-shaped moving plate slidably connected inside the mounting slot. A limiting component is provided on the moving plate; when the two adjusting mechanisms clamp the bottle cap, the two limiting components clamp the end of the bottle cap away from the mounting plate.

[0005] As a further improvement to this technical solution, the limiting component includes an inverted U-shaped movable frame that is slidably connected to one side of the movable plate, and a mounting block is fixedly connected to the bottom of the movable frame near the movable plate.

[0006] As a further improvement to this technical solution, a hard anti-slip pad is fixedly connected to the bottom of the movable plate on the side away from the movable frame, and an elastic anti-slip pad is fixedly connected to the side of the mounting block away from the movable frame.

[0007] As a further improvement to this technical solution, a cylinder is fixedly connected to the upper side of the movable frame. The piston rod of the cylinder passes through the movable frame and is fixedly connected to the upper side of the movable plate. During the extension and retraction process, the piston rod of the cylinder drives the movable frame to move upward or downward.

[0008] As a further improvement to this technical solution, the driving mechanism includes a threaded rod rotatably connected inside the mounting plate, with both ends of the threaded rod located inside the mounting groove.

[0009] As a further improvement to this technical solution, the threaded rod is provided with threads in opposite directions near both ends, the threads are located inside the mounting groove, and the two movable plates are respectively threadedly connected to the threaded rod near both ends.

[0010] As a further improvement to this technical solution, a worm gear is coaxially fixedly connected to the threaded rod near the middle position, and a worm is rotatably connected inside the mounting plate, with the worm gear meshing with the worm.

[0011] As a further improvement to this technical solution, a pneumatic motor for driving the worm gear to rotate is fixedly connected to the upper side of the mounting plate. During the rotation of the worm gear, the threaded rod is driven to rotate through the worm wheel, and the threaded rod drives the two moving plates to move closer to or further away from each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The adjustable capping head clamping device of this filling machine, during the clamping process of bottle caps of different thicknesses, the piston rod of the cylinder extends and retracts, driving the moving frame to move up or down to adjust the distance between the moving plate and the mounting block. The pneumatic motor drives the threaded rod to rotate through the worm gear, which in turn drives the two moving plates to move. This allows the hard anti-slip pad and the elastic anti-slip pad to clamp and fix the upper and lower ends of the bottle cap respectively, improving the clamping effect of the clamping device on the bottle cap. Therefore, it is not necessary to change the clamping device to be suitable for bottle caps of different thicknesses, thereby improving the capping efficiency of the capping machine.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example Please see Figure 1 - Figure 7 As shown, the purpose of this embodiment is to provide an adjustable capping head clamping device for a filling machine, including a mounting plate 1. A mounting frame is fixedly connected to the upper side of the mounting plate 1. During the use of this clamping device, it is installed on the capping machine through the mounting frame. The capping machine drives the clamping device to move. Two mounting slots 11 are symmetrically opened on the mounting plate 1, and two adjusting mechanisms 3 are symmetrically arranged on the mounting plate 1. A driving mechanism 2 is provided inside the mounting plate 1. The driving mechanism 2 drives the two adjusting mechanisms 3 to move towards or away from each other. In the initial state, the two adjusting mechanisms 3 are located far apart from each other. The capping machine drives the clamping device to move and transfer it to the outside of the bottle cap, so that the bottle cap is located between the two adjusting mechanisms 3. Then the driving mechanism 2 drives the two adjusting mechanisms 3 to move. The two adjusting mechanisms 3 clamp and fix the bottle cap as they move towards each other. The adjusting mechanism 3 includes an I-shaped movable plate 31 slidably connected inside the mounting groove 11. The movable plate 31 is equipped with limiting components. When the two adjusting mechanisms 3 clamp the bottle cap, the two limiting components clamp the end of the bottle cap away from the mounting plate 1, so that the adjusting mechanism 3 clamps the side wall of the bottle cap near the top and bottom, improving the stability of the bottle cap during the capping process. A support plate is fixedly connected to the lower side of the mounting plate 1. When the adjusting mechanism 3 clamps the bottle cap, the top of the bottle cap abuts against the support plate to prevent the bottle cap from moving upward. The bottle cap is clamped and fixed by the two adjusting mechanisms 3 and the support plate to prevent the bottle body from squeezing the bottle cap during the process of the capping machine rotating and tightening the bottle cap, causing the bottle cap to shift. This ensures that the capping machine rotates the bottle cap and fixes it to the top of the bottle body.

[0017] refer to Figure 3 - Figure 5 The drive mechanism 2 includes a threaded rod 21 rotatably connected inside the mounting plate 1. The two ends of the threaded rod 21 are located inside the mounting groove 11. The threaded rod 21 has threads with opposite helical directions near the two ends. The threads are located inside the mounting groove 11. Two moving plates 31 are respectively threadedly connected to the threaded rod 21 near the two ends. Several bellows tubes are provided on the outside of the threaded rod 21. The two ends of the bellows tubes are respectively fixedly connected to the side wall of the moving plate 31 and the inner wall of the mounting groove 11. The bellows tubes prevent dust from adhering to the threaded rod 21, ensuring that the threaded rod 21 drives the moving plate 31 to move during rotation. A worm gear 22 is coaxially fixedly connected to the threaded rod 21 near the middle position. A worm 23 is rotatably connected inside the mounting plate 1. The worm gear 22 meshes with the worm 23. A pneumatic motor 24 that drives the worm 23 to rotate is fixedly connected to the upper side of the mounting plate 1. During the rotation of the worm 23, the threaded rod 21 is driven to rotate through the worm gear 22. The threaded rod 21 drives the two moving plates 31 to move towards or away from each other.

[0018] refer to Figure 6 and Figure 7The limiting component includes an inverted U-shaped moving frame 33 slidably connected to one side of the moving plate 31. A mounting block 34 is fixedly connected to the bottom of the moving frame 33 near the moving plate 31. A hard anti-slip pad 32 is fixedly connected to the bottom of the moving plate 31 away from the moving frame 33. The hard anti-slip pad 32 is used to clamp the upper end of the bottle cap. Since the upper end of the bottle cap is solid, the hard anti-slip pad 32 applies a large squeezing force to the upper end of the bottle cap, thereby improving its clamping effect. An elastic anti-slip pad 35 is fixedly connected to the side of the mounting block 34 away from the moving frame 33. The elastic anti-slip pad 35 is used to clamp the lower end of the bottle cap. Since the lower end of the bottle cap is hollow, its strength is low and it is easy to deform. The elastic anti-slip pad 35 provides friction while buffering the pressure on the bottle cap, reducing the probability of the lower end of the hollow bottle cap being clamped and deformed. It perfectly balances clamping force and protection, making it easy for the capping machine to tighten the bottle cap to the top of the bottle. A cylinder 36 is fixedly connected to the upper side of the movable frame 33. The piston rod of the cylinder 36 passes through the movable frame 33 and is fixedly connected to the upper side of the movable plate 31. During the extension and retraction process, the piston rod of the cylinder 36 drives the movable frame 33 to move up or down to adjust the distance between the movable plate 31 and the mounting block 34, so that it can be used for bottle caps of different thicknesses, thereby further improving the clamping effect of the clamping device on the bottle cap.

[0019] When using this device: The staff installs the clamping device on the capping machine using the mounting bracket. In the initial state, the two adjustment mechanisms 3 are far apart from each other. During the capping process, the capping machine drives the clamping device to move, so that the cap is located between the two adjustment mechanisms 3. At this time, the top of the cap contacts the support plate. Subsequently, the piston rod of the cylinder 36 drives the moving frame 33 to move during the extension and retraction process, so as to adjust the distance between the moving plate 31 and the mounting block 34, so that the mounting block 34 corresponds to the lower end of the cap. Subsequently, the pneumatic motor 24 drives the worm gear 23 to rotate, which in turn drives the threaded rod 21 to rotate via the worm wheel 22. During the rotation, the threaded rod 21 drives the two moving plates 31 to move towards the bottle cap, so that the hard anti-slip pad 32 and the elastic anti-slip pad 35 clamp the upper and lower ends of the bottle cap respectively. The capping machine moves the clamping device and the bottle cap to the top of the bottle body, and tightens the bottle cap on the top of the bottle body through the capping machine.
