Description

Technical Field

[0001] This utility model relates to the technical field of equipment for beverage can production lines, and in particular to a cage for spraying inlets inside beverage cans. Background Technology

[0002] In the aluminum can production line, the cage device is a key component that guides the aluminum cans through processes such as internal spraying and cleaning. The accuracy of its spacing directly affects the smoothness of the can transfer and the processing quality.

[0003] Traditional beverage can cage adjustment relies on a "pin + perforated plate" positioning method, with the cage spacing limited by fixed holes on the perforated plate. When a new can type needs to be produced, the perforated plate must be re-processed and replaced. However, both manual drilling and machine repositioning have certain accuracy deviations, resulting in long changeover cycles and high costs.

[0004] In addition, the same size cans from different can manufacturers may have a height deviation of ±0.1-0.2 mm due to differences in molds or materials. Traditional equipment requires operators to make fine adjustments to each cage one by one, which not only relies on the experience of skilled workers, but may also pose safety hazards due to working at height, such as climbing equipment to adjust the pins. Utility Model Content

[0005] Therefore, it is necessary to provide a can cage for spraying into an inner can to address the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides a can cage for spraying inside an aluminum can, including a fixed sliding plate assembly, a movable sliding plate assembly, and multiple lifting mechanisms. Each lifting mechanism includes a worm gear lift, a lifting rod, a first fixed mounting plate, a second fixed mounting plate, and a movable mounting plate. The first fixed mounting plate is fixedly connected to the fixed sliding plate assembly, the movable mounting plate is fixedly connected to the movable sliding plate assembly, the lifting rod is fixedly connected to the first and second fixed mounting plates, and the lifting rod is slidably connected to the movable mounting plate. The worm gear lift is fixedly connected to the second fixed mounting plate, and the output end of the worm gear lift is fixedly connected to the movable mounting plate. Adjacent worm gear lifts are connected by a universal coupling.

[0007] Optionally, the fixed sliding plate assembly and the movable sliding plate assembly are symmetrically arranged. The symmetrical structure ensures that the force is evenly distributed during the transport of the cans, reducing the risk of tilting or jamming and improving operational stability.

[0008] Optionally, both the fixed slide plate assembly and the movable slide plate assembly include a flat slide plate, side plates, reinforcing ribs, wear-resistant strips, and pressure plates. Side plates are fixed to both sides of the flat slide plate, and reinforcing ribs are fixed between the flat slide plate and the side plates. Wear-resistant strips are installed on the ends of the side plates away from the reinforcing ribs, and pressure plates are fixed to the side plates, abutting against the wear-resistant strips. The reinforcing ribs improve overall rigidity, the wear-resistant strips reduce frictional wear from the cans, and the pressure plates fix the wear-resistant strips for easy replacement and maintenance, extending the equipment's service life and reducing operating noise.

[0009] Optionally, the lifting mechanism is distributed along the trajectory of the fixed sliding plate assembly. A right-angle steering device is installed on the second fixed mounting plate of the lifting mechanism at one end of the trajectory. A hand crank is installed at the input end of the right-angle steering device, and the output end of the right-angle steering device is connected to the input end of the worm gear jack via a coupling. The hand crank, in conjunction with the right-angle steering device, transfers the operating position to the outside of the equipment, avoiding the risks of working at height. Furthermore, the efficient transmission of force is achieved through gear transmission, allowing a single person to complete the entire process adjustment, thus reducing labor costs.

[0010] Optionally, an adjustment plate is mounted on the second fixed mounting plate. The adjustment plate has a scale groove, and adjustment scales are provided on both sides of the scale groove. The scale groove and adjustment scales help operators intuitively control the adjustment amount. Combined with actual measurement data from aluminum cans, calibration can be completed quickly, reducing the number of trial and error attempts and improving changeover efficiency.

[0011] Optionally, a guide sleeve is fixed to the movable mounting plate, and the lifting rod is slidably connected to the guide sleeve. The guide sleeve restricts the radial displacement of the movable mounting plate, preventing shaking or jamming during adjustment and ensuring the linear accuracy and stability of the cage spacing adjustment.

[0012] Optionally, two lifting rods are provided, with the fixed slide plate assembly and the movable slide plate assembly located between the two lifting rods. The dual lifting rod structure forms symmetrical support, ensuring that the movable slide plate assembly is subjected to uniform force during lifting, preventing tilting or jamming, and ensuring the synchronicity and reliability of the adjustment action.

[0013] Optionally, the lifting rod has an external thread at one end near the first fixed mounting plate, and the lifting rod is connected to the first fixed mounting plate by at least two nuts, with the first fixed mounting plate located between the two nuts. The threaded connection, coupled with the double nut locking, allows for quick adjustment of the initial installation height of the lifting rod, meeting the installation reference requirements of different production lines, while ensuring a secure and stable connection during operation.

[0014] Optionally, the lifting rod has an internally threaded hole axially formed at one end near the second fixed mounting plate, and the second fixed mounting plate is threadedly connected to the internally threaded hole by bolts. This bolted connection facilitates the disassembly and assembly of the second fixed mounting plate. When maintenance of the worm gear jack or replacement of parts is required, it can be quickly disassembled without affecting the overall structure, thus improving equipment maintenance efficiency.

[0015] The beneficial effects of this technical solution are as follows: Through the precision transmission of the worm gear jack and the linkage of the universal coupling, the synchronous movement of all moving slide components can be controlled by a single operating point, resulting in high adjustment accuracy. This avoids the tediousness of traditional fine-tuning of each slide individually and significantly improves adjustment efficiency and spacing consistency. Attached Figure Description

[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.

Figure 1 Only one universal coupling 7 is shown in the image.

[0019] The fixed sliding plate assembly 1 and the movable sliding plate assembly 2 are symmetrically arranged. The symmetrical structure ensures that the force is evenly distributed during the transport of the cans, reducing the risk of tilting or jamming and improving operational stability.

[0020] By operating one of the worm gear jacks 31, and with the linkage of the universal coupling 7, the remaining worm gear jacks 31 can be driven to operate, thereby driving the movable slide plate assemblies 2 to move synchronously, moving closer to or away from the fixed slide plate assembly 1. This avoids the tediousness of traditional individual fine-tuning and improves adjustment efficiency. Furthermore, the worm gear jacks 31 have high adjustment precision, which can significantly improve adjustment efficiency and spacing consistency.

[0021] In some embodiments, please refer to Figure 3 To enhance the structural strength and wear resistance of the fixed sliding plate assembly 1 and the movable sliding plate assembly 2, both assemblies include a flat sliding plate 11, side plates 12, reinforcing ribs 13, wear-resistant strips 14, and pressure plates 15. Side plates 12 are fixed to both sides of the flat sliding plate 11, and reinforcing ribs 13 are fixed between the flat sliding plate 11 and the side plates 12. Wear-resistant strips 14 are installed at the end of the side plates 12 away from the reinforcing ribs 13, and pressure plates 15 are fixed to the side plates 12, abutting against the wear-resistant strips 14. The reinforcing ribs 13 improve overall rigidity, the wear-resistant strips 14 reduce friction wear from the cans, and the pressure plates 15 secure the wear-resistant strips 14 for easy replacement and maintenance, extending the equipment's service life and reducing operating noise.

[0022] In some embodiments, please refer to Figure 1 and Figure 2 To facilitate manual operation of the lifting mechanism 3, the lifting mechanism 3 is arranged along the trajectory of the fixed slide assembly 1.

A hand crank 5 is installed at the input end of the right-angle steering gear 4. The output end of the right-angle steering gear 4 is connected to the input end of the worm gear lift 31 through a coupling 8. The coupling 8 is a rigid connector.

[0023] The hand crank 5, in conjunction with the right-angle steering gear 4, moves the operating position to the outside of the equipment, avoiding the risks of working at heights. Furthermore, the gear transmission enables efficient force transmission, allowing a single person to complete the entire process adjustment and reducing labor costs.

[0024] In some embodiments, please refer to Figure 1 and Figure 2 To provide operators with a visual reference for adjusting the scale, an adjustment plate 6 is installed on the second fixed mounting plate 34. The adjustment plate 6 has a scale groove 61, and adjustment scales are provided on both sides of the scale groove 61.

[0025] The graduated groove 61 and the adjustment scale help operators intuitively control the adjustment amount. Combined with the actual measurement data of the aluminum can, calibration can be completed quickly, reducing the number of trial and error and improving the efficiency of changeover.

[0028] In some embodiments, please refer to Figure 1 and Figure 2 To improve the connection stability of the fixed skateboard assembly 1 and the movable skateboard assembly 2, two lifting rods 32 are set, with the fixed skateboard assembly 1 and the movable skateboard assembly 2 located between the two lifting rods 32.

[0029] The two lifting rods 32 form a symmetrical support structure, which makes the movable slide plate assembly 2 subjected to uniform force during the lifting process, preventing tilting or jamming, and ensuring the synchronicity and reliability of the adjustment action.

[0030] In some embodiments, please refer to Figure 2 To facilitate the installation and positioning of the lifting rod 32, an external thread is provided at one end of the lifting rod 32 near the first fixed mounting plate 33. The lifting rod 32 is connected to the first fixed mounting plate 33 by two nuts 38, and the first fixed mounting plate 33 is located between the two nuts 38.

[0031] The threaded connection, secured with double nuts 38, allows for quick adjustment of the initial installation height of the lifting rod 32, meeting the installation reference requirements of different production lines while ensuring a secure and stable connection during operation.
