Description

Technical Field

[0001] The utility model relates to the technical field of wooden tableware grinding, in particular to a wooden tableware grinding machine. Background Art

[0002] When polishing wooden tableware, the tableware is usually fixed on a polishing table and then polished by a handheld polisher. During the polishing process, different positions of the tableware need to be polished, so the position angle of the polisher needs to be adjusted.

[0003] However, since the grinder is held in the hands of the operator, when the position of the grinder is adjusted, the root of the power cord of the grinder will be twisted and bent, which will cause the outer sheath of the power cord to be damaged or even break from the root over time, causing damage to the grinder and affecting the grinding of wooden tableware. Utility Model Content

[0004] The purpose of the utility model is to provide a wooden tableware grinder to solve the problem that the root of the power cord of the grinder proposed in the above background technology will be twisted and bent, which will cause the outer skin of the power cord to be damaged over a long period of time, or even break from the root, causing damage to the grinder.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a wooden tableware grinder, comprising a grinder body, the rear side of the grinder body being fixedly connected to a power cord, the front end of the grinder body being fixedly connected to a driving mechanism, the output end of the driving mechanism being connected to a grinding plate, the lower surface of the driving mechanism being fixedly connected to a protective cover, the rear side of the grinder body being fixedly connected to a fixing plate close to the power cord, the inner side of the fixing plate being rotatably connected to a screw, the outer surface of the screw being threadedly connected to a limiting plate one, the inner side of the limiting plate one being fixedly connected to a spring, the lower surface of the spring being fixedly connected to a buffer plate, the lower surface of the buffer plate being movably connected to the limiting plate two, and the outer surface of the limiting plate one being slidably connected to a guide rod.

[0006] Preferably, a brush plate is movably connected to the inner side of the protective cover, fixed blocks are fixedly connected to both ends of the brush plate, bolts are threadedly connected to the inner side of the fixed block, and a cleaning brush is fixedly connected to the outer surface of the brush plate.

[0007] Preferably, the fixing plate is in a plate-like shape, and the fixing plate is symmetrically fixedly connected to both sides of the power cord in multiple groups. The screw is in a rod-like shape, and the screw is threadedly connected to the limit plate 1, and the screw is slidingly connected to the limit plate 2. Its function is to rotate the screw, thereby driving the limit plate 1 to slide toward the limit plate 2 on the rear side of the grinder body through the rotation of the screw, thereby facilitating the limiting of the root of the power cord.

[0008] Preferably, the limit plate 1 and the limit plate 2 are both arched plates, the limit plate 1 is slidably connected to the rear side of the grinder body, and the limit plate 2 is fixedly connected to the rear side of the grinder body. Its function is to limit the power cord between the limit plate 1 and the limit plate 2 through the contact between the limit plate 1 and the limit plate 2, thereby preventing the root of the power cord from twisting or bending during the movement of the grinder body, resulting in damage to the outer skin and leakage.

[0009] Preferably, an annular groove is provided on the inner side of the limiting plate 1, and the buffer plate is slidably connected to the inner side of the groove. The spring is spirally shaped, and one end of the spring is fixedly connected to the limiting plate 1, and one end of the spring is fixedly connected to the buffer plate. Its function is that after the limiting plate 1 contacts the limiting plate 2, the power cord will be limited between the buffer plate and the limiting plate 2, and under the elastic action of the spring, the power cord will have a certain amount of movement space.

[0010] Preferably, the brush plate is in the shape of an arc plate, the fixing block is in the shape of a block, and the bolts are in two groups. The brush plate is connected to the protective cover and the fixing block through bolt threads and is fixedly connected to the inner side of the protective cover. Its function is to connect the fixing block and the protective cover through bolt threads, thereby fixing the brush plate to the inner side of the protective cover. At the same time, it is also convenient for disassembly of the brush plate, and convenient for replacement or cleaning of the brush plate.

[0011] Preferably, the cleaning brushes are in groups, and the cleaning brushes are in contact with the edge of the grinding plate. Their function is to clean the wood chips on the edge of the grinding plate by rubbing the edge of the grinding plate during the rotation of the grinding plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By rotating the screw, one end of the limit plate 1 moves downward on the outer surface of the screw, and the other end of the limit plate 1 slides downward synchronously on the outer surface of the guide rod, so that the limit plate 1 contacts the limit plate 2. When the limit plate 1 moves downward until it contacts the power cord, the power cord is limited between the buffer plate and the limit plate 2 under the elastic action of the spring, thereby preventing the root of the power cord from twisting or bending when the grinder body moves, thereby protecting the power cord. At the same time, under the elastic action of the spring, the power cord has a certain amount of space to move, preventing the outer skin of the power cord from being damaged.

[0014] 2. The fixing block and the protective cover are connected by bolt threads, so that the brush plate is fixedly connected to the inner side of the protective cover. When the sanding plate is used to sand wooden tableware, a large amount of wood chips will adhere to the bottom and edge of the sanding plate. The wood chips at the bottom of the sanding plate are easy to clean, but the wood chips at the edge are more difficult to clean. By arranging a brush plate and a cleaning brush connected on the inner side of the protective cover, when there are wood chips on the edge of the sanding plate, the cleaning brush can clean the wood chips on the edge of the sanding plate through the rotation of the sanding plate, thereby facilitating the sanding of wooden tableware by the sanding plate.
