Description

Technical Field

[0001] This utility model relates to the technical field of tank processing equipment, specifically to a necking machine anti-jamming device. Background Technology

[0002] In the processing of cans such as metal beverage cans and food cans, the necking machine is a key piece of equipment for reducing the size of the can's neck. The can needs to be conveyed to a transfer star wheel via a conveyor mechanism, and then the transfer star wheel will transport the can to the subsequent processing station.

[0003] However, the feeding process of existing necking machines has significant drawbacks: due to the relatively small size of most tank models and the influence of conveying inertia during transport, the tanks are prone to pushing and shoving each other before entering the transfer star wheel. Simultaneously, the high-speed movement of the tanks generates considerable impact force due to inertia. This pushing and impact can cause tank deformation, leading to tank jamming. Can jamming interrupts the production process, reduces production efficiency, increases equipment maintenance costs, and results in substantial economic losses for the company. Utility Model Content

[0004] The purpose of this invention is to overcome the defect of easy can jamming during the feeding of existing necking machines, and to provide a can jamming prevention device for necking machines. This device can effectively guide and limit the can during the feeding process. At the same time, before the can enters the transfer star wheel, it gradually increases the degree of contact and resistance to smoothly buffer the impact force, reduce the moving speed, and avoid the can being pushed and deformed. It can also adapt to the feeding needs of cans of different specifications and inertia.

[0005] To achieve the above objectives, this utility model provides a necking machine anti-jamming device, including a side plate, a lower guide plate fixed to the lower part of the side plate, and an upper guide plate fixed to the upper part of the side plate. The side plate, the lower guide plate, and the upper guide plate together form an inclined channel for the can to pass through, and the can can move along the inclined channel toward the transfer star wheel.

[0006] A bracket is fixedly connected to the side plate, and a first adjustment device and a second adjustment device are installed on the bracket. A first adjustment frame is hinged to the output end of the first adjustment device. The first adjustment device is used to adjust the distance between the first adjustment frame and the lower guide plate. A second adjustment frame is fixedly installed to the output end of the second adjustment device. The first adjustment device is used to adjust the distance between the second adjustment frame and the lower guide plate. The free end of the second adjustment frame is slidably connected to the second adjustment device. Multiple flexible rollers are rotatably installed on the second adjustment frame. An opening is provided on the upper guide plate, which allows the flexible rollers to move and enter the inclined channel, so that the flexible rollers can contact the tank in the inclined channel before the tank enters the transfer star wheel.

[0007] The first and second adjusting devices can work together to achieve precise control of the flexible roller position. Since the first adjusting frame is hinged to the first adjusting device, and the second adjusting frame is slidably connected to the first adjusting frame, adjusting the position of the first adjusting frame via the first adjusting device, or vice versa, allows adjustment of the position and angle of the first adjusting frame relative to the lower guide plate. This, in turn, adjusts the position of each flexible roller, enabling them to contact the tank and provide a buffering effect, adapting to tanks of different sizes. For example, along the inclined channel from inlet to outlet, the distance between each flexible roller and the lower guide plate can be progressively reduced. This ensures that the tank, as it moves along the channel, contacts each flexible roller sequentially, with the degree of contact gradually increasing as the distance decreases. This progressively increases the resistance to the tank, achieving a smooth reduction in tank speed and preventing deformation or jamming due to excessive resistance at a single moment.

[0008] Furthermore, the free end of the first adjusting frame is provided with a slider, and the second adjusting frame has a U-shaped notch for the free end of the first adjusting frame to enter. The inner wall of the U-shaped notch is provided with a groove, and the slider is slidably connected to the groove. Through the cooperation of the slider and the groove, the first adjusting frame and the second adjusting frame can be kept stable when moving relative to each other, avoiding deviation during the adjustment process.

[0009] Furthermore, the flexible roller is a sponge roller. The sponge material has excellent elasticity and cushioning properties. When the sponge roller contacts the tank, it can utilize its flexibility to smoothly buffer the impact force of the tank, gradually reducing the moving speed and preventing high-speed collisions or pushing of the tank. Simultaneously, the sponge roller can rotate with the movement of the tank, reducing frictional resistance between it and the tank. It provides cushioning resistance solely through the deformation of the sponge itself, ensuring that the tank can still move smoothly during the gradual deceleration process.

[0010] Furthermore, the axes of all flexible rollers are located on the same reference plane. This arrangement allows the limiting force and buffering force of multiple flexible rollers on the tank to be evenly distributed. Even when the reference plane is not parallel to the lower guide plate, the force exerted by the same flexible roller on the tank remains consistent, avoiding tilting or deformation of the tank due to uneven force, and further improving the anti-jamming effect.

[0011] Furthermore, the first adjusting device includes a first bolt, a first nut, and a first lifting frame. The first bolt is fixedly mounted on a bracket, and two first nuts are threaded onto the first bolt. The first lifting frame is fitted onto the first bolt and located between the two first nuts, and the first lifting frame is hinged to the first adjusting frame. By adjusting the position of the two first nuts on the first bolt, the first lifting frame can be moved up and down along the first bolt. The hinged connection between the first lifting frame and the first adjusting frame allows the first adjusting frame to rotate around the hinge point, thereby adjusting the distance between the first adjusting frame and the lower guide plate.

[0012] Furthermore, a hinge seat is fixed on the first adjusting frame, and the first lifting frame is hinged to the hinge seat via a pin. By setting the hinge seat, the relative rotation between the first adjusting frame and the first lifting frame is facilitated, ensuring a smooth adjustment process.

[0013] Furthermore, the second adjusting device includes a second bolt, a second nut, and a second lifting frame. The second bolt is fixedly mounted on the bracket, and two second nuts are threaded onto the second bolt. The second lifting frame is fitted onto the second bolt and located between the two second nuts, and is fixedly connected to the second adjusting frame. By adjusting the position of the two second nuts on the second bolt, the second lifting frame can be moved up and down along the second bolt. The second lifting frame is fixedly connected to the second adjusting frame, and the up and down movement of the second lifting frame can directly drive the up and down movement of the second adjusting frame, thereby adjusting the distance between the second adjusting frame and the lower guide plate.

[0014] As an alternative, both the first and second adjusting devices can be made without bolts and nuts, and instead use linear actuators.

[0015] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. By cooperating with the first and second adjustment devices, the distance between the flexible rollers and the lower guide plate can be gradually reduced along the direction from the inlet to the outlet of the inclined channel. This allows the tank to contact each flexible roller in sequence as it moves along the inclined channel, with the degree of contact gradually increasing. This achieves a gradual reduction in the tank speed, reduces tank pushing and jamming, ensures the tank enters the transfer star wheel smoothly, significantly reduces the risk of production interruption, improves production efficiency, and reduces enterprise operating costs. 2. The elastic properties of the flexible rollers ensure that the tank only undergoes slight deformation upon contact, preventing scratches, dents, or neck deformation on the tank surface, thus ensuring the quality of tank processing and reducing material waste caused by tank scrapping.

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] Please see Figures 1 to 5 This application provides a necking machine anti-jamming device, including a side plate 1, a lower guide plate 2 fixed to the lower part of the side plate 1, and an upper guide plate 3 fixed to the upper part of the side plate 1. Two side plates 1 are provided, and the side plate 1, lower guide plate 2, and upper guide plate 3 together form an inclined channel 4 for the can 23 to pass through. The can 23 can move along the inclined channel 4 towards the transfer star wheel 22. The above are all prior art and can be referenced. Figure 6 .

[0019] The necking machine anti-jamming device provided in this embodiment has the following improvements: A bracket 5 is fixedly connected to the side plate 1, and a first adjusting device 6 and a second adjusting device 7 are installed on the bracket 5. A first adjusting frame 8 is hinged to the output end of the first adjusting device 6. The first adjusting device 6 is used to adjust the distance between the first adjusting frame 8 and the lower guide plate 2. A second adjusting frame 9 is fixedly installed to the output end of the second adjusting device 7. The first adjusting device 6 is used to adjust the distance between the second adjusting frame 9 and the lower guide plate 2. The free end of the second adjusting frame 9 is slidably connected to the second adjusting device 7. Five flexible rollers 10 are rotatably installed on the second adjusting frame 9 through bearings.

[0020] In this embodiment, the flexible roller 10 is a sponge roller. The sponge material has good elasticity and cushioning properties. When the sponge roller comes into contact with the tank 23, it can utilize its flexibility to smoothly buffer the impact force of the tank 23 and gradually reduce the moving speed, avoiding high-speed collisions or pushing of the tank 23. At the same time, the sponge roller can rotate with the movement of the tank 23, reducing the frictional resistance between it and the tank 23. The buffering resistance is provided only by the deformation of the sponge itself, ensuring that the tank 23 can still move smoothly during the gradual deceleration process.

[0021] An opening 11 is provided on the upper guide plate 3, which allows the flexible roller 10 to move into the inclined channel 4, so that the flexible roller 10 can contact the tank 23 in the inclined channel 4 before the tank 23 enters the transfer star wheel 22.

[0022] In this embodiment, both the first adjusting device 6 and the second adjusting device 7 are linear actuators, specifically servo cylinders, servo hydraulic cylinders, or electric cylinders. When an electric cylinder is used, the cylinder body of the electric cylinder is fixed on the bracket 5, and the piston rods of the two electric cylinders are respectively connected to the first adjusting frame 8 and the second adjusting frame 9, so that the first adjusting frame 8 can quickly form a preset tilt angle, thereby accurately controlling the spacing gradient between each flexible roller 10 and the lower guide plate 2, adapting to the conveying needs of tanks 23 with different inertia, making the operation more convenient and efficient, and suitable for automated production lines.

[0023] The first adjusting device 6 and the second adjusting device 7 can cooperate to achieve precise control of the position of the flexible roller 10. Since the first adjusting frame 8 is hinged to the first adjusting device 6 and the second adjusting frame 9 is slidably connected to the first adjusting frame 8, the position of the first adjusting frame 8 can be adjusted by adjusting the first adjusting device 6, or the position of the second adjusting frame 9 can be adjusted by adjusting the second adjusting device 7. This can adjust the position and angle of the first adjusting frame 8 relative to the lower guide plate 2, thereby adjusting the position of each flexible roller 10, so that the flexible roller 10 can contact the tank 23 and play a buffering role, adapting to tanks 23 of different sizes.

[0024] In this embodiment, the distance between each flexible roller 10 and the lower guide plate 2 is set to decrease sequentially along the inlet to outlet direction of the inclined channel 4, so that the tank 23 can contact each flexible roller 10 sequentially during the movement along the channel, and the degree of contact gradually increases as the distance decreases, thereby gradually increasing the resistance to the tank 23, realizing a smooth reduction in the speed of the tank 23, and avoiding deformation or jamming of the tank 23 due to excessive resistance at one time.

[0025] For example, when conveying a tank 23 with a diameter of 80mm, the channel height is set to 84mm. The distances between the five flexible rollers 10 and the lower guide plate 2 are approximately 79mm, 78mm, 77mm, 76mm, and 75mm respectively along the moving direction of the tank 23, forming a spacing gradient. As the tank 23 moves along the inclined channel 4, it contacts the flexible rollers 10 in sequence, and the resistance gradually increases. However, the flexible rollers 10 can all be deformed under force to allow the tank 23 to pass through. The speed of the tank 23 gradually decreases, thus smoothly entering the transfer star wheel 22 without deformation or tank jamming throughout the process.

[0026] In some embodiments, to achieve a sliding connection between the first adjusting bracket 8 and the second adjusting bracket 9, please refer to [reference needed]. Figure 3 The first adjusting frame 8 has a slider 12 at its free end, with two sliders 12 arranged vertically. The second adjusting frame 9 has a U-shaped notch 13 for the free end of the first adjusting frame 8 to enter. The inner wall of the U-shaped notch 13 has a groove 14, and the slider 12 is slidably connected to the groove 14. Through the cooperation of the slider 12 and the groove 14, the first adjusting frame 8 and the second adjusting frame 9 can be kept stable during relative movement, avoiding deviation during the adjustment process.

[0027] In some embodiments, please refer to Figure 1 and Figure 2 The axes of all flexible rollers 10 are located on the same reference plane. This arrangement allows the limiting force and buffering force of multiple flexible rollers 10 on the tank 23 to be evenly distributed. Even when the reference plane is not parallel to the lower guide plate 2, the force exerted by the same flexible roller 10 on the tank 23 remains consistent, avoiding tilting or deformation of the tank 23 due to uneven force, and further improving the anti-jamming effect.

[0028] In some other embodiments, please refer to Figure 5 Alternatively, instead of using automatic linear actuators, the first adjusting device 6 and the second adjusting device 7 can be manually operated. Specifically, the first adjusting device 6 includes a first bolt 15, a first nut 16, and a first lifting frame 17. The first bolt 15 is fixedly mounted on the bracket 5, and two first nuts 16 are threaded onto the first bolt 15. The first lifting frame 17 is fitted onto the first bolt 15 and located between the two first nuts 16. The first lifting frame 17 is hinged to the first adjusting frame 8. By adjusting the position of the two first nuts 16 on the first bolt 15, the first lifting frame 17 can be moved up and down along the first bolt 15. The first lifting frame 17 is hinged to the first adjusting frame 8, and the up and down movement of the first lifting frame 17 can cause the first adjusting frame 8 to rotate around the hinge point, thereby adjusting the distance between the first adjusting frame 8 and the lower guide plate 2.

[0029] A hinge seat 18 is fixed on the first adjusting frame 8, and the first lifting frame 17 is hinged to the hinge seat 18 via a pin. By setting the hinge seat 18, the relative rotation between the first adjusting frame 8 and the first lifting frame 17 is facilitated, ensuring a smooth adjustment process.

[0030] The second adjusting device 7 includes a second bolt 19, a second nut 20, and a second lifting frame 21. The second bolt 19 is fixedly mounted on the bracket 5, and two second nuts 20 are threaded onto the second bolt 19. The second lifting frame 21 is fitted onto the second bolt 19 and located between the two second nuts 20. The second lifting frame 21 is fixedly connected to the second adjusting frame 9. By adjusting the position of the two second nuts 20 on the second bolt 19, the second lifting frame 21 can be moved up and down along the second bolt 19. The second lifting frame 21 is fixedly connected to the second adjusting frame 9, and the up and down movement of the second lifting frame 21 can directly drive the up and down movement of the second adjusting frame 9, thereby adjusting the distance between the second adjusting frame 9 and the lower guide plate 2.

[0031] The first adjusting device 6 and the second adjusting device 7 are both linear actuators, specifically servo cylinders, servo hydraulic cylinders, or electric cylinders. When an electric cylinder is used, the cylinder body of the electric cylinder is fixed on the bracket 5, and the piston rods of the two electric cylinders are connected to the first adjusting frame 8 and the second adjusting frame 9 respectively, so that the first adjusting frame 8 can quickly form a preset tilt angle, thereby accurately controlling the spacing gradient between each flexible roller 10 and the lower guide plate 2, adapting to the conveying needs of tanks 23 with different inertia, making the operation more convenient and efficient, and suitable for automated production lines.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
