Description

Technical Field

[0001] The utility model relates to the technical field of can turning tools, in particular to a turning device for can production. Background Art

[0002] In the canned food production process, since the openings of the prepared cans are generally facing downward, the openings facing downward will affect the normal filling operation. At this time, it is usually necessary to flip the cans with the openings facing downward. The flipping of the cans is an important link, which is directly related to the efficiency of the production line and the product quality.

[0003] Traditional flipping methods often rely on manual operation or simple mechanical devices. Manual flipping relies on manual operation by workers, which is not only labor-intensive, but also difficult to ensure flipping speed and accuracy, which can easily cause damage or contamination of cans and affect product quality. Although simple mechanical flipping can reduce the labor burden to a certain extent, such devices are often complex in structure, difficult to maintain, and have a low degree of automation, and cannot meet the needs of modern high-speed production lines.

[0004] At present, in order to achieve the effect of portable and efficient flipping, a corresponding flipping device is usually used. The flipping devices on the market all use a clamp to clamp the can, and then use the motor to drive the can to complete the flipping operation. However, the size of the clamp on this type of flipping device is constant, and it can only clamp cans of a specified size, and cannot clamp cans of various outer diameters, which affects the clamping effect and brings inconvenience to users. In view of this, we propose a flipping device for can production. Utility Model Content

[0016] 1. The utility model can utilize the cylinder to drive the clamping protrusion to clamp the can by setting the turning assembly. In addition, the servo motor can drive the U-shaped frame and the can to turn over and complete the turning operation. Since the cross-section of the clamping groove is in the shape of an isosceles trapezoid, the cans with different outer diameters can be clamped within the maximum width and minimum width of the clamping groove. The rubber pad can prevent the clamping protrusion from directly contacting the can and causing it to be broken, thereby achieving the effect of facilitating turning and being able to clamp cans with a variety of different outer diameters.
