Description

Technical Field

[0001] The utility model belongs to the technical field of metal can processing equipment, and particularly relates to an automatic turning device for metal cans. Background Art

[0002] A metal can, commonly known as a pop-top can, has a lid and body produced separately and then assembled together. There are two materials used in pop-top cans: aluminum and tinplate. Aluminum's high recycling value has led to its widespread use in pop-top cans for environmental reasons. Aluminum can be recycled and reused, reducing material costs. However, existing production lines lack automatic can flipping devices during polishing or painting. Workers often manually handle the cans on sandpaper during recycling and polishing. Furthermore, when painting, workers rotate the cans beneath the paint sprayer, holding them in their hands. This manual rotation not only consumes significant labor but also leads to low efficiency.

[0003] To this end, an automatic turning device for metal cans with the announcement number "CN213647031U" includes a workbench, a fixed plate fixedly connected to the upper end of the workbench, and a rotating column 1, a rotating column 2, a rotating column 3 and a rotating column 4 rotatably connected inside the fixed plate, the circumferential surface of the rotating column 1 is fixedly connected to the sprocket 1, the rear end of the rotating column 1 is fixedly connected to the motor, and the lower end of the motor is fixedly connected to the motor base; the circumferential surface of the rotating column 4 is fixedly connected to the pulley 2, and the pulley 1 and the pulley 2 are connected by a belt; the front end of the rotating column 2 is fixedly connected to a circular plate, the front end of the circular plate is fixedly connected to a sleeve, and the sleeve is rotatably connected to a rotating shaft inside the sleeve, the upper end of the rotating shaft is fixedly connected to a handle, the lower end of the rotating shaft is fixedly connected to a bevel gear, the bevel gear is meshed with a toothed disc, the front end of the toothed disc is fixedly connected to a volute tooth, and the volute tooth is meshed with a slider, thereby realizing automation to replace manpower in turning over the metal cans, and multiple metal cans can be turned over at the same time.

[0004] However, for the above-mentioned automatic flipping device for metal cans, although the rotating shaft is rotated by turning the handle, causing the gear disc engaged with it to rotate, since the gear disc is engaged with volute teeth, the volute teeth rotate accordingly under the rotation of the gear disc, and then the slider moves under the guidance of the slide groove, and the movement of the slider drives the movement of the clamping block, completing the clamping and fixing of the metal can, the following more obvious defects still exist during use: However, the above-mentioned clamping and fixing method requires manual clamping and fixing of multiple metal cans one by one, and after the processing is completed, personnel are required to manually remove the metal cans from the clamp one by one. Although this method can be used for flipping and spraying, the problem of slowing down the spraying process progress due to hand clamping of the metal can will affect the production capacity of the metal can.
