Description

Technical Field

[0001] The present application relates to the technical field of metal can production, and in particular to a device for rolling the body of a metal can. Background Art

[0002] Metal cans are a common container, usually made of metal materials such as iron, aluminum, stainless steel, etc. Metal cans can be used to store and transport various items.

[0003] Rolling is the most basic production process in metal can production. In the actual production process, the cut steel plate is usually rolled using a special rolling machine to make the steel plate into a cylindrical shape. There are many different types of rolling machines on the market.

[0004] The existing rolling machine does not have a deburring program. Before rolling, the edge of the plate needs to be polished and then transported to the rolling machine for rolling, so as to avoid injuries when manually handling the semi-finished product. However, this not only increases the equipment footprint, but also wastes time and effort.

[0005] Therefore, it is necessary to provide a metal can body rolling device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0013] Furthermore, the limiting member includes a retaining ring and two sliding keys; the retaining ring is sleeved on the movable rod and is located below the propeller member; the two sliding keys are arranged on the outside of the retaining ring, and the angle between the two sliding keys is a right angle; the end of the sliding key away from the retaining ring is a matching structure with the annular groove.

[0014] Furthermore, the annular groove is a wave-shaped curved groove, the amplitude of the annular groove is constant, and the spacing between the wave peaks of the annular groove is constant; therefore, when the moving rod rotates, the sliding key is moved in the annular groove through the retaining ring; thereby, the moving rod moves up and down with the grinding head, maximizing the utilization rate of the working surface of the grinding knife, and indirectly ensuring the best grinding effect.

[0015] Furthermore, a rolling assembly is provided between the two frames, and the rolling assembly is provided on one side of the grinding assembly;
