The two pressure rollers 17 and the two support rollers 111 are arranged at the upper and lower positions of the iron accessory base plate 3, and the four vertical rollers 116 are arranged at the front and rear positions of the iron accessory base plate 3. The grinding mechanism 2 includes an adjusting frame 21, a second screw rod 22, an adjusting handle 23, a transmission mechanism 24, two mounting plates 25, two grinding motors 26 and two grinding discs 27. The second screw rod 22 and the adjusting handle 23 are both rotatably connected to the adjusting frame 21. The two mounting plates 25 are both threadedly sleeved on the outer wall of the second screw rod 22. The two grinding motors 26 are respectively fixedly connected to the two mounting plates 25, and the output ends of the two grinding motors 26 are fixedly sleeved with grinding discs 27. The two grinding discs 27 are arranged at the upper and lower positions of the iron accessory base plate 3.

[0024] In this embodiment, the screw rod 22 is made of a bidirectional screw rod, and the two mounting plates 25 are symmetrically arranged about the middle part of the screw rod 22. The transmission mechanism 24 includes a belt and two pulleys. The two pulleys are fixedly sleeved on the outer walls of the screw rod 22 and the adjusting handle 23 respectively. The belt is sleeved on the outer walls of the two pulleys, and the two pulleys are driven to rotate by the belt, so that when the adjusting handle 23 rotates, the screw rod 22 can be driven to rotate.

[0025] In this embodiment, the lower end of the adjustment frame 21 is rotatably connected to a pulley 29, which can facilitate the movement of the adjustment frame 21 and reduce the friction of movement. A guide rod 210 is fixedly connected to the front end surface of the adjustment frame 21 near the lower position, and a handle 28 is fixedly connected between the top plate and the bottom plate near the rear end of the adjustment frame 21. The front end of the guide rod 210 is set through the mounting seat 11, and the guide rod 210 is used to limit the forward and backward movement of the adjustment frame 21.

[0026] In this embodiment, the four mounting brackets 12 are respectively fixedly connected to the four corners of the upper end surface of the mounting base 11. Four sliding shafts 13, two guiding shafts 14, two first lead screws 15, four sliders 16 and four springs 18 are respectively arranged in the four mounting brackets 12. The two sliding shafts 13 and the two guiding shafts 14 at the rear end are fixedly connected in the mounting brackets 12, and the two sliding shafts 13 and the two first lead screws 15 at the front end are rotatably connected in the mounting brackets 12. The outer walls of the four sliding shafts 13 are all sleeved with sliders 16 in a sliding manner. The pressure roller 17 is rotatably connected between the front and rear sliders 16. The outer walls of the two first lead screws 15 are all sleeved with mounting blocks 19 in a threaded manner. A driving motor 112 is fixedly connected to one of the mounting blocks 19. The outer walls of the two guiding shafts 14 are all sleeved with guiding blocks 110 in a sliding manner. The front and rear ends of one of the supporting rollers 111 are respectively rotatably connected between the mounting block 19 and the guiding block 110, and the front and rear ends of the other supporting roller 111 are respectively fixedly and rotatably connected to the output end of the driving motor 112 and the guiding block 110. By driving the driving motor 112 to drive one of the supporting rollers 111 to rotate, power is provided for the transportation of the iron accessory substrate 3.

[0027] In this embodiment, fixing plates 113 are fixedly connected to the outer walls of the four mounting brackets 12. Screws 114 are threadedly sleeved on the four fixing plates 113. Slide rods 115 are sleeved on the four fixing plates 113 in a sliding manner. One end of the screw 114 is rotatably sleeved with a U-shaped plate. Rotating the screw 114 can drive the U-shaped plate to move. One end of the slide rod 115 is fixedly connected to the outer wall of the U-shaped plate. The slide rod 115 limits the U-shaped plate to prevent it from rotating along with the screw 114. The four vertical rollers 116 are respectively rotatably connected to the four U-shaped plates. By using the vertical rollers 116 to limit the front and rear of the iron accessory substrate 3, when the grinding disc 27 moves back and forth, the iron accessory substrate 3 can be kept stable and prevented from shifting.

[0028] In this embodiment, the four springs 18 are respectively movably sleeved on the outer ends of the four sliding shafts 13. The lower ends of the four springs 18 are respectively fixedly connected to the upper end surfaces of the four sliders 16. Elastic pressure is applied to the sliders 16 through the springs 18, so as to drive the pressure roller 17 to apply elastic pressure to the iron accessory substrate 3 through the sliders 16.

[0029] In this embodiment, the upper ends of the two sliding shafts 13 at the front end respectively penetrate through the top plate of the mounting bracket 12 and are connected with rotating caps. The upper ends of the two first lead screws 15 and the two guiding shafts 14 are respectively fixedly connected to the lower ends of the four sliding shafts 13. By rotating the rotating caps to drive the sliding shafts 13 at the front end to rotate, the first lead screws 15 are further driven to rotate.

[0030] It should be noted that the present invention is a grinding device for electric iron accessories. When in use, the sliding shaft 13 at the front end is rotated to drive the screw 15 to rotate, and then the threaded mounting block 19 is driven to move up and down, so as to adjust the height of the support roller 111 according to the thickness of the iron accessory base plate 3, so as to avoid the pressure of the pressure roller 17 being too large or too small, which affects the transportation of the iron accessory base plate 3. At the same time, the screw 114 is rotated to drive the front and rear mounting vertical rollers 116 to move relative to each other, and the front and rear end rolling clamps of the iron accessory base plate 3 are clamped by the vertical rollers 116. The adjusting handle 23 is then rotated to drive the screw 22 to rotate through the transmission mechanism 24, thereby driving the two mounting plates 25 to move relative to each other, thereby driving the two grinding discs 27 to fit on the front and back surfaces of the iron accessory substrate 3, and starting the grinding motor 26 to drive the grinding discs 27 for grinding. At the same time, the adjusting frame 21 is pushed and pulled by the handle 28, and the grinding disc 27 can be moved back and forth relative to the iron accessory substrate 3 for grinding under the action of the pulley 29 and the guide rod 210, thereby improving the comprehensiveness of the grinding.
