Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a device for rolling threads on the sealing opening of aluminum can blanks for aluminum can processing. Background Technology

[0002] Aluminum cans are a common type of metal beverage container, mainly used for packaging beverages and food. Aluminum cans are lightweight, corrosion-resistant, and easily recyclable, thus enjoying widespread use in the market. During the aluminum can manufacturing process, thread rolling of the sealing opening of the aluminum can blank is an important step. Thread rolling creates high-precision threads with a high surface finish at the sealing opening, providing a standard interface for the aluminum can and facilitating connection and fit with other components (such as the can lid), ensuring a tight seal.

[0003] However, in actual operation, since aluminum is usually soft and aluminum cans are hollow, workers usually need to place an inner support inside each aluminum can before feeding it into the rolling equipment to ensure that the aluminum can blank is not damaged during processing. This leads to a reduction in the processing efficiency of aluminum cans. Therefore, a rolling thread device for sealing the aluminum can blank is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a thread rolling device for sealing the aluminum can blank in aluminum can processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thread rolling device for sealing the aluminum can blank in aluminum can processing, comprising:

[0006] Workbench;

[0007] An internal support assembly includes an internal support column, a sliding column, a fixed frame, a turntable, and a connecting column. Multiple internal support columns, sliding columns, and connecting columns are provided. The connecting column connects to the sliding column and the internal support column. The fixed frame is fixedly installed on the worktable and has multiple sliding grooves. Each sliding column is slidably placed in each of the sliding grooves. The turntable is rotatably installed a predetermined distance above the fixed frame and has multiple arc-shaped grooves. Each sliding column is slidably placed in each of the arc-shaped grooves.

[0008] A rolling assembly is mounted on the worktable.

[0009] As a preferred embodiment, the rolling assembly includes a rotating belt and rolling studs. The rotating belt is provided in pairs and is horizontally fixedly connected to each other. The rolling studs are provided in multiple pairs. One of the rolling studs in each pair is rotatably mounted on the inner wall of one of the rotating belts, and the other rolling stud in each pair is rotatably mounted on the inner wall of another rotating belt. The multiple pairs of rolling studs are spaced apart, and the pair of rotating belts are symmetrically distributed with the axial direction of the inner support column as the center.

[0010] As a preferred embodiment, the rolling assembly further includes a driving wheel, a driven wheel, a transmission belt, and a rolling motor. Multiple driving wheels, driven wheels, transmission belts, and rolling motors are provided. The driving wheel is connected to one of the rolling studs, the driven wheel is connected to another rolling stud, the transmission belt is connected to the driving wheel and the driven wheel, and the output shaft of the rolling motor is connected to the driving wheel.

[0011] As a preferred embodiment, the worktable has a fixed cylinder, the inner support assembly further includes a rotating motor, the fixed frame is fixedly installed on the upper end of the fixed cylinder, the lower end of the turntable is rotatably inserted into the fixed cylinder, the rotating motor is installed inside the fixed cylinder, and the output shaft of the rotating motor is connected to the lower end of the turntable.

[0012] As a preferred embodiment, the worktable further includes a roller groove, and the rolling assembly further includes balls and support columns. Multiple balls and support columns are provided. Multiple support columns are fixedly installed at intervals on the lower end face of the rotating ring below. The balls are rotatably placed at the lower end of the support columns and fit against the roller groove.

[0013] As a preferred embodiment, the upper end face of the sliding column has a limiting plate, the lower end face of the limiting plate is attached to the upper end face of the turntable, and the cross-sectional diameter of the limiting plate is greater than the width of the arc groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes an internal support assembly, comprising an internal support column, a sliding column, a fixed frame, a turntable, and a connecting column. The connecting column connects to the sliding column and the internal support column. The fixed frame has a sliding groove, in which the sliding column is placed. The turntable is rotatably mounted on the fixed frame and has an arc-shaped groove, in which the sliding column is slidably placed. Workers insert multiple aluminum cans to be threaded onto multiple internal support columns one by one. Then, they push the support column, causing the threaded screws to rotate. Next, the rotating motor drives the turntable to rotate axially around the fixed cylinder, and the sliding column slides along the sliding groove, causing the internal support column to move closer to the threaded screws. This, in turn, positions the aluminum cans between each pair of threaded screws, enabling the threading of multiple aluminum can sealing ports and improving production efficiency.

[0016] This invention incorporates multiple ball bearings and support columns. The support columns are fixedly installed at intervals on the lower end face of the rotating ring. The ball bearings are rotatably positioned at the lower end of the support columns, fitting into the groove. When a worker pushes the support columns, the inner support column is positioned between a pair of rotating rings. At this time, the ball bearings roll in the groove on the worktable. By incorporating ball bearings, the friction between the inner support column and the worktable is reduced, thus improving the service life of the equipment. Attached Figure Description

[0032] Working principle and usage process of this utility model:

[0033] First, the worker pushes the support column 38, which in turn drives a pair of rotating rings 31 to rotate along the groove 12, so that the inner support column 21 is placed between the pair of rotating rings 31.

[0034] Subsequently, the workers insert multiple aluminum cans to be threaded one by one onto multiple inner support columns 21; then push the support column 38, and the rotating ring 31 drives the threaded screws 32 to rotate as well; then, the rotating motor 26 drives the turntable 24 to rotate axially around the fixed cylinder 11. The rotating turntable 24 drives multiple sliding columns 22 in the arc groove 241 to slide along the sliding groove 231, so that the inner support column 21 connected to the sliding column 22 by the connecting column 25 moves towards the threaded screws 32, thereby driving the aluminum can sealing port on the inner support column 21 to be placed between each pair of threaded screws 32. In this way, the threaded operation of multiple aluminum can sealing ports can be performed, improving production efficiency.

[0035] After the aluminum can is fixed, multiple starting rolling motors 36 drive the drive wheel 33 to rotate. Through the transmission belt 35, the driven wheel 34 also rotates, so that each pair of rolling studs 32 rotates synchronously around its own axis, thereby rolling the threads of the aluminum can sealing opening, demonstrating the automation level of the equipment.
