Description

Technical Field

[0001] The utility model relates to the technical field of metal can processing, in particular to a metal can body processing, sealing and shaping device. Background Art

[0002] Metal cans are commonly used containers for canned food and beverages. In order to ensure the sealing effect, metal cans need to be shaped to reduce the probability of leakage.

[0003] In the related technology, a search found a solution for a metal can body processing, sealing and shaping device (Announcement No. CN217800164U), which can grind and shape the periphery of the aluminum sheet while stamping. There is no need for workers to manually grind the aluminum sheet after stamping, which makes the processing speed faster and the work efficiency higher.

[0004] However, the above solution performs shaping processing on the outer surface of the metal can, but when there are pits on the surface of the metal can, the surface of the metal can cannot be leveled; the structural strength of the metal can is limited, and processing from the outer surface of the metal can is likely to cause micro-deformation problems at the edge of the metal tube. Utility Model Content

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a metal can body processing, sealing and shaping device, comprising a base, a negative pressure machine installed inside the base, a placement tube provided on the upper surface of the base, a positioner installed on the side of the placement tube, and the positioner extending into the placement tube, a suction cup provided inside the placement tube, and the suction cup is connected to the negative pressure machine. When a metal can is placed in the placement tube, it is fixed by the suction cup, which is not easy to cause deformation of the metal can and has a good fixing effect;

[0007] The bracket is installed on the surface of the base, a first cylinder is installed on the upper surface of the bracket, a motor is installed at the lower end of the first cylinder, two second cylinders are installed at the output end of the motor, the second cylinder is installed with a roller frame, and the roller frame is installed with a shaping roller.

[0008] Furthermore, an air supply box is installed inside the placement tube, the suction cup is connected to the air supply box, and the negative pressure machine draws air from the air supply box. The air supply box has a connecting pipe, and the connecting pipe is connected to the negative pressure machine through a hose. Several suction cups are drawn air by the air supply box, and metal pipes of different sizes can be fixed.

[0009] Furthermore, the positioner includes a third cylinder and a tripod connected to the third cylinder. The tripod passes through the placement tube and is connected to a buffer pad. The buffer pad supports the upper and lower parts of the metal tube to prevent the metal can from tilting.

[0010] Compared with the existing technology, the beneficial effects of the utility model are: the metal can is placed in the placement tube, the position of the buffer pad is adjusted according to the diameter of the metal can, keeping the metal can in the center of the placement tube, the suction cup sucks the bottom surface of the metal can to ensure that the metal can does not shake, the first cylinder controls the two shaping rollers to move to the inner and outer surfaces of the metal can, the second cylinder pushes the shaping rollers to fit the metal can, and the motor controls the shaping rollers to rotate to shape the metal can, ensuring that the surface of the metal can is flat and of high quality.

[0017] The bracket 2 is mounted on the surface of the base 1, and a first cylinder 3 is mounted on the upper surface of the bracket 2. A motor 5 is mounted on the lower end of the first cylinder 3, and two second cylinders 6 are mounted on the output end of the motor 5. The second cylinder 6 is mounted with a roller frame 8, and the roller frame 8 is mounted with a shaping roller 9. The second cylinder 6 adjusts the position of the shaping roller 9. The position of the shaping roller 9 can be changed according to the size of the metal can, and metal cans of different sizes can be shaped.

[0018] In this embodiment, if Figure 1 As shown, an air supply box 17 is installed inside the placement tube 13, and the suction cup 18 is connected to the air supply box 17. Several suction cups 18 are arranged in a ring shape, which is convenient for fixing metal cans of different sizes. The negative pressure machine 10 exhausts the air supply box 17.

[0019] In this embodiment, if Figure 1 The air supply box 17 shown has a connecting pipe 12, which passes through the base 1. The connecting pipe 12 is connected to the negative pressure machine 10 through a hose 11.
