Description

Technical Field

[0001] The utility model relates to the field of related equipment for aluminum bottle production, in particular to a grinding device for the inner wall of an aluminum bottle. Background Art

[0002] Aluminum bottles are bottles made of aluminum metal materials. In order to improve the production quality of aluminum bottles, it is necessary to grind the inner and outer walls of the aluminum bottles after they are processed and formed. In the prior art, electric equipment equipped with grinding blocks is mainly used to grind the inner walls of aluminum bottles, as shown in the Chinese utility model "A dust-absorbing inner wall grinding device for aluminum bottle processing" with patent number CN202320114316.8 (authorization announcement number CN218927296U). The grinding device includes a control seat, a connecting seat and a grinding block. A connecting rod is provided on one side of the control seat, and the connecting seat is arranged at one end of the connecting rod away from the control seat. Electric telescopic rods and grinding blocks are arranged on both sides of the connecting seat. One end of the electric telescopic rod is connected to the grinding block, so that the two grinding blocks can be against the inner walls of the main body of the aluminum bottle with different inner diameters, so that the grinding device can perform a relatively complete grinding of the aluminum bottle.

[0003] Although the grinding block of the above-mentioned grinding equipment can adapt to aluminum bottles with different inner diameters, the lengths of existing aluminum bottles are not the same. Figure 1 The aluminum bottle shown will have other problems. The aluminum bottle includes a cylindrical bottle body 1′, one end of the bottle body 1′ is provided with an opening 11′, and the other end of the bottle body 1′ is the bottle bottom. The bottle body 1′ is relatively long, and the grinding block of the grinding equipment is required to be able to extend into the bottom of the inner wall of the bottle body 1′ to grind the inner wall of the bottle body 1′; if the grinding block of the above-mentioned grinding equipment is used to grind the inner wall of the bottle body 1′, the grinding block of the grinding equipment is set at the free end of the connecting rod, and a longer connecting rod is required to extend into the bottom of the bottle body 1′ through the opening 11′ for grinding. However, during the grinding process of the grinding equipment, since the grinding head will continue to rotate for grinding, it may cause the longer connecting rod to shake slightly, thereby causing the rotation of the grinding head to be unstable, thereby affecting the grinding effect of the inner wall of the bottle body 1′. In addition, the specifications of existing aluminum bottles are also different. Although the above-mentioned grinding equipment drives the grinding blocks to fit the inner walls of aluminum bottles with different inner diameters through the telescopic rod, the degree of automation of the grinding equipment is low. It is necessary to manually adjust the position of the grinding equipment according to the inner diameter of the aluminum bottle so that both grinding blocks can be extended into the aluminum bottle so that the grinding blocks can fully fit the inner wall of the aluminum bottle. Therefore, the above-mentioned grinding equipment makes the workers' labor intensity high and the production efficiency low. Therefore, it is necessary to make further improvements to the grinding equipment for the inner wall of aluminum bottles. Summary of the invention
