[0002] Metal can manufacturing refers to the process of producing various sealed containers using metal materials (mainly tinplate, aluminum, or chrome-plated iron) through processes such as stamping, stretching, welding, painting, and printing. These containers are typically used for packaging food, beverages, chemical products, aerosols, etc.

[0003] Currently, a necking machine is required for the necking process of metal cans. Before processing, the metal can needs to be fitted onto the outer wall of a rotating fixture for fixation. However, the existing necking machine's metal can fitting fixing accessories cannot be adjusted according to different lengths of metal can fittings, which easily leads to the metal can fitting having a longer pre-processing length. This can easily cause deformation of the metal can neck during processing, and improvements are needed. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-3This utility model provides a technical solution: a metal can body necking forming adjustment device, including a frame 3, a limit plate 2 rotatably connected to the top side of the frame 3, a first motor 1 mounted on the top side of the frame 3, the shaft of the first motor 1 being drivenly connected to the shaft on the other side of the limit plate 2. In this structure, the first motor 1 drives the limit plate 2 to rotate automatically via a belt and pulley. The first motor 1 can be automatically controlled by a PLC to improve the level of intelligence and processing accuracy. A reciprocating ball screw mechanism 5 is provided on the top side of the frame 3, and a mounting bracket 6 is fixedly connected to the top of the reciprocating ball screw mechanism 5. This reciprocating ball screw mechanism 5 is composed of a fixed seat, a screw, a screw slide, and a motor. The mounting bracket 6 is fixedly connected to the top of the screw slide. Structure 5 can drive the mounting frame 6 and the accessories on the mounting frame 6 to move horizontally, facilitating the adjustment of the working position of the necking wheel 14. The necking wheel 14 is located inside the mounting frame 6, and is composed of a wheel body and a frame body. A second motor 15 is fixedly connected to one side of the frame body of the necking wheel 14. The second motor 15 can drive the wheel body of the second motor 15 to rotate automatically. This structure allows the second motor 15 to drive the necking wheel 14 to rotate automatically, making the necking wheel 14 contact the metal can 8 to be processed, achieving uniform processing of the outer wall of the metal can 8. This part is existing technology and will not be described in detail here. A fourth electric cylinder 16 is fixedly connected to one end of the mounting frame 6. The fourth electric cylinder 16 can also be controlled by a PLC to realize the driving mechanism in this device. With the coordinated operation of the equipment, one end of the fourth electric cylinder 16 is fixedly connected to the necking wheel 14 frame. This fourth electric cylinder 16 can push the necking wheel 14 to move back and forth. The movement of the necking wheel 14 allows it to move closer to or further away from the metal can 8 to be processed, thus adjusting the pressure on the metal can 8 and facilitating necking processing of the necking wheel 14. The greater the pressure, the smaller the neck opening; the lower the pressure, the larger the neck opening. A sleeve 7 is fixedly connected to one side of the limiting plate 2. The outer wall of the sleeve 7 has openings that are evenly spaced in a circular pattern. The positions of these openings correspond to the positions of the third electric cylinder 13 and the second support block 12. This third electric cylinder 13 can push the second support block 12 to fit against the inner wall of the metal can 8 to be processed. Multiple sets of the third electric cylinder 13 and the second support block 12 are provided. The third electric cylinder 13 and the second support block 12 are staggered with the second electric cylinder 10 and the first support block 9. This structure ensures that the third electric cylinder 13 and the second support block 12 will not interfere with each other when working with the second electric cylinder 10 and the first support block 9, thus guaranteeing the normal operation of the device. The second electric cylinder 10 can push the first support block 9 to fit against the inner wall of the metal can 8 to be processed. The second electric cylinder 10 is installed on the outer wall of the sleeve 7. One end of the second electric cylinder 10 is connected to the first support block 9. The first electric cylinder 4 is fixedly connected inside the sleeve 7. A sliding rod 11 is inserted into one side of the sleeve 7. One side of the sliding rod 11 is connected to the first electric cylinder 4. The third electric cylinder 13 is fixedly connected to the outer wall of the sliding rod 11. The first electric cylinder 4 can push the sliding rod 11 to automatically extend and retract.To facilitate adjustment based on the length of the metal can 8 to be processed, one end of the third electric cylinder 13 is connected to the second support block 12. The metal can 8 to be processed is fitted onto the outer wall of the sleeve 7. Both the first support block 9 and the second support block 12 are supported on the inner wall of the metal can 8. The sliding rod 11 and the sleeve 7 form a sliding connection. The sliding rod 11 of this device can automatically extend and retract inside the sleeve 7. Therefore, the length between the sleeve 7 and the sliding rod 11 can be adjusted according to the length of the metal can 8 to be processed. This ensures that the metal can 8 is in the most securely fixed state while maintaining the reserved processing position, thereby facilitating the processing of the metal can 8 and improving its processing accuracy.

[0019] Working principle: When using this metal can necking forming adjustment device, firstly, the metal can 8 to be processed is fitted onto the outer wall of the sleeve 7. The second electric cylinder 10 on the outer wall of the sleeve 7 supports the first support block 9 to fit against the inner wall of the metal can 8 to be processed, so that the metal can 8 to be processed is stably connected to the sleeve 7. Then, according to the length of the metal can 8 to be processed, the position of the second support block 12 on the outer wall of the slide rod 11 is adjusted. During adjustment, the first electric cylinder 4 pushes the slide rod 11 to extend from the inside of the sleeve 7 to a suitable position. Then, the third electric cylinder 13 pushes the second support block 12 to support the inner wall of the metal can 8 to be processed. Then, the position of the necking wheel 14 is adjusted by the reciprocating ball screw mechanism 5 and the fourth electric cylinder 16, so that the necking wheel 14 contacts the metal can 8 to be processed for processing.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
