[0020] As Figure 1 、 Figure 2 and Figure 3 As shown in

[0021] a multi-head planar sander for scissors of the present utility model includes a platform 1. A plurality of positioning grooves 15 are provided on the platform 1. Templates 2 are placed in the positioning grooves 15. Mold cavities 3 matching the unilateral scissors are provided on the templates 2. A plurality of driving rollers 12 are arranged in an offset manner up and down at one end of the platform 1. A plurality of annular sandpapers 9 are installed outside the driving rollers 12. Driving mechanisms for driving the annular yarn to move horizontally and vertically up and down are installed on both sides of the platform 1.

[0022] In this embodiment, a rectangular opening is provided on the bottom surface of the mold cavity 3. A positioning opening communicating with the outside is provided on the bottom surface of the positioning groove 15 corresponding to the rectangular opening. A push plate 13 is provided at the bottom of the platform 1. Top plates 4 are installed on the push plate 13 corresponding to the positioning openings. The other ends of the top plates 4 pass through the positioning openings and are inserted into the rectangular openings and are flush with the bottom surface of the mold cavity 3. An electric push rod 14 for driving the push plate 13 to move is installed on the bottom surface of the push plate 13. A bracket is installed between the electric push rod 14 and the platform 1.

[0023] In this embodiment, grooves are provided on both sides of the driving roller 12 where the annular sandpaper 9 is located. Positioning blocks 10 are arranged in the grooves. One end of each positioning block 10 extends to the outside and is in contact with the outer side surface of the annular sandpaper 9. A plurality of compression springs are installed at the other end of each positioning block 10, and the other ends of the compression springs are installed on the inner wall surface of the groove. After the driving roller is removed from the fixed frame, the positioning block can be squeezed to retract into the groove. After the blocking of the positioning block is lost, the annular sandpaper can be directly removed from the driving roller, which facilitates disassembly.

[0024] In this embodiment, a plurality of support columns 5 are installed on the bottom surface of the side fixing plate 8.

[0025] In this embodiment, the grinding mesh number of the annular sandpaper 9 facing the platform 1 is the lowest, and the grinding mesh number gradually increases as it is farther away from the platform 1.

[0026] Among them, this device only grinds the two parallel side surfaces of the scissors, and does not grind and sharpen the inclined shear surfaces on the scissors.

[0027] During use, different templates are placed according to the styles of the scissors, so that different scissors can be placed in the corresponding mold cavities. The scissors can be positioned through the mold cavities to ensure the stability of the placement.

[0028] After the placement is completed, the motor is started. The start of the motor drives the driving roller and the annular sandpaper. Then the electric slide is started. The electric slide can drive the annular sandpaper to move towards the platform. During the movement, the air cylinder can be started to retract the piston rod of the air cylinder. The retraction of the piston rod drives the fixed frame, the driving roller and the annular sandpaper, so that the annular sandpaper contacts the surface of the scissors, and the pressure acting on the scissors can be changed by the degree of descent, increasing the adaptability.

[0029] Among them, the grinding mesh number of the annular sandpaper facing the platform is the lowest, and the grinding mesh number gradually increases as it is farther away from the platform. The surface can be quickly coarsely ground by the annular yarn with a small mesh number, and the uneven convex points on the surface can be quickly removed. And the surface can be finely ground by the annular sandpaper with a large mesh number, improving the grinding quality and efficiency.

[0030] After the grinding is completed, the annular sandpaper can be moved in the reverse direction. After the annular sandpaper is moved away from the platform, the electric push rod can be started. The electric push rod can drive the movement of the push plate and the top plate. The scissors can be directly pushed outwards by the top plate, which facilitates the disassembly of the scissors.

[0031] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
