DETAILED DESCRIPTION

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a curved surface polishing machine for scissors, comprising a first grinding block 1 and a second grinding block 2, wherein the first grinding block 1 and the second grinding block 2 are both arranged in an arc-shaped structure, and a grinding channel 3 with a curved surface structure is formed between the first grinding block 1 and the second grinding block 2. A grinding portion 9 with a curved surface structure is protruded on one side surface of the first grinding block 1 facing the second grinding block 2, and the grinding channel 3 is narrowed inwardly toward one side of the grinding portion 9. A fixed plate 4 is installed at one end of the second grinding block 2, and the other end of the fixed plate 4 extends to the outside of the first grinding block 1, and is installed with a driving mechanism for driving the first grinding block 1 to move quickly for grinding.

[0023] In this embodiment, a positioning opening 14 is provided on the fixed plate 4 opposite to the first grinding block 1, and a positioning block 5 is installed on the top surface of the first grinding block 1. The positioning block 5 is arranged through the positioning opening 14, and a limiting portion 6 is protruded on one side surface of the positioning block 5. A gap is formed between the limiting portion 6 and the fixed plate 4. The limiting portion can limit the descending distance of the first grinding block, thereby avoiding excessive downward movement.

[0024] In this embodiment, a plurality of mounting grooves are provided on the end surface of the first grinding block 1 facing the fixed plate 4 , and compression springs 13 are installed in each of the mounting grooves. The other ends of the compression springs 13 are installed on the fixed plate 4 .

[0025] In this embodiment, the driving mechanism includes a motor 8 and an eccentric wheel 12. A circular groove 10 is provided on the outer surface of the first grinding block 1. A pressure-bearing portion 11 is protruded on the inner ring surface of the circular groove 10. The eccentric wheel 12 is arranged inside the circular groove 10. The rotating shaft of the motor 8 passes through the fixed plate 4 and is fixedly connected to the eccentric wheel 12.

[0026] In this embodiment, a groove 7 is provided on the fixing plate 4 opposite to the grinding channel 3; grinding lines are provided on the grinding channel 3 and the grinding portion 9, so that the grinding lines on the grinding portion can align with the blade to achieve a polishing operation.

[0027] In this embodiment, a gap is formed between the fixing plate 4 and the first grinding block 1 for the first grinding block 1 to move up and down, so that the first grinding block can rise smoothly.

[0028] When in use, the head of the curved scissors is inserted into the grinding channel, and the handle of the curved scissors is placed above the groove. As the curved scissors continue to move, the blade on the curved scissors contacts the grinding part.

[0029] After the above is completed, the motor is started. The start of the motor drives the eccentric wheel. The eccentric wheel can push the pressure part upward during the rotation. The movement of the pressure part drives the first grinding block, so that the first grinding block rises steadily along the positioning port. After the eccentric wheel is removed from the pressure part, the rebound of the compression spring can push the first grinding block downward, so that the first grinding block descends steadily. Since the distance between the fixed plate and the first grinding block is close, the first grinding block only moves up and down a small range. The first grinding block that moves up and down quickly can quickly polish the blade, greatly increasing efficiency.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
