DETAILED DESCRIPTION OF THE INVENTION

[0020] In order to deepen the understanding and recognition of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described and introduced in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments, and no formal restrictions are imposed on this embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1 - 3, the present invention provides a technical solution: a continuous surface polishing device for steel, including a support block 1 and an adjustment plate 12. There is a connection cavity in the middle of the lower end of the support block 1, and a polishing wheel 4 is rotatably connected in the middle of the connection cavity. A guide plate 2 is fixedly connected to the right side of the support block 1, and a plurality of guide wheels 3 are rotatably connected to the side end of the guide plate 2 to reduce friction. There is a fixed plate 5 at the upper end of the support block 1. Both sides of the lower end of the fixed plate 5 are hinged with upper swing arms 8. The lower ends of the two upper swing arms 8 are rotatably connected to a lower swing arm 7. The lower ends of the two lower swing arms 7 are hinged to the support block 1. A limiting column 6 is fixedly connected to the middle of the lower end of the fixed plate 5. A sliding sleeve 9 is slidably connected in the middle of the limiting column 6. A first return spring is fixedly connected between the sliding sleeve 9 and the fixed plate 5. The first return spring is sleeved on the limiting column 6. There is an installation cavity 15 at the lower end of the support block 1. The installation cavity 15 is located on the right side of the polishing wheel 4. A rotation control mechanism 14 is rotatably connected in the installation cavity 15. The rotation control mechanism 14 is composed of a rotation plate 141, an auxiliary groove 142, a connecting plate 143, and a control hook 144. A protruding part 17 is fixedly connected to the inner side wall of the installation cavity 15. A bite adjustment mechanism 11 is slidably connected in the middle of the protruding part 17. The bite adjustment mechanism 11 is composed of a rotating disk 111, a bite hook 112, and an adjustment tooth 113. There is a counter 21 in the middle of the support block 1. The counter is a commonly used part in the prior art. The non-disclosure of its specific structure in this solution does not affect the integrity of this solution. A button 23 is fixedly connected to the side wall of the installation cavity 15. A motor is arranged at the side end of the support block. The motor drives the polishing wheel to work. The button 23 is electrically connected to the motor, thereby controlling the start and stop of the polishing wheel.

[0022] Auxiliary arms 10 are hinged to both sides of the sliding sleeve 9. The two upper swing arms 8 are arranged in a V shape. The auxiliary arms 10 are rotatably connected to the middle of the upper swing arms 8. The upper swing arms 8 and the lower swing arms 7 are arranged in a V-shaped structure. The guide plate 2 guides the steel. When the steel hits the guide plate 2 and lifts the support block 1, the upper swing arms 8 and the lower swing arms 7 rotate accordingly, thereby changing the height of the support block 1. At the same time, the polishing wheel 4 is tightly pressed against the surface of the steel to polish the steel. The mutual cooperation of the upper swing arms 8, the lower swing arms 7, and the sliding sleeve 9 enables the support block 1 to always move vertically, avoiding affecting the polishing of the steel.

[0023] The tail end of the rotating plate 141 is a columnar structure. The tail end of the rotating plate 141 is rotatably connected to the installation cavity 15. The auxiliary groove 142 is located at the top end of the rotating plate 141. The connecting plate 143 is fixedly connected to the middle of the upper end of the rotating plate 141. The control hook 144 is fixedly connected to the upper end of the connecting plate 143. The installation cavity 15 is an inverted T-shaped structure. The lower end of the installation cavity 15 is fixedly connected with a first spring piece 16. The first spring piece 16 is a V-shaped structure. The top end of the first spring piece 16 abuts against the auxiliary groove 142. When the rotating plate 141 is impacted by the steel material into the installation cavity 15, the rotating plate 141 squeezes and deforms the first spring piece 16. When the steel material leaves, the first spring piece 16 can bounce the rotating plate 141 away.

[0024] The rotating disk 111 is rotatably connected to the installation cavity 15. The engaging hook 112 is fixedly connected to the left side of the rotating disk 111. The adjusting tooth 113 is fixedly connected to the right side of the rotating disk 111. The top end of the engaging hook 112 faces upward, and the top end of the control hook 144 faces downward. The engaging hook 112 and the control hook 144 are engaged with each other. The adjusting plate 12 is an L-shaped structure. A plurality of connecting teeth 13 are fixedly connected to the left side of the adjusting plate 12. The distance between adjacent two connecting teeth 13 is the same. The connecting teeth 13 are meshed and connected with the adjusting teeth 113. A second return spring is fixedly connected between the upper end of the adjusting plate 12 and the button 23. When the rotating plate 141 enters the installation cavity 15, the control hook 144 squeezes the engaging hook 112, driving the rotating disk 111 to rotate. The rotating disk 111 drives the adjusting plate 12 to move through the adjusting teeth 113. At this time, the adjusting plate 12 moves downward, and the second return spring pulls the button 23 downward, thereby starting the motor and the polishing wheel rotates to work. When the steel material leaves, under the action of the first spring piece 16, the rotating plate 141 moves out of the installation cavity 15, the control hook 144 pulls the engaging hook 112, and the adjusting plate 12 moves upward, squeezing the button 23 through the second return spring, thereby closing the motor.

[0025] The upper end of the adjusting plate 12 is located at the upper end of the protruding part. The friction plate 19 is inlaid on the inner wall of the installation cavity 15. The limiting plate 18 is fixedly connected to the right inner wall of the adjusting plate 12. The limiting plate 18 is a T-shaped structure. The limiting plate 18 is slidably connected to the protruding part. When the adjusting plate 12 moves upward, it needs to pass through the friction plate 19, slowing down the moving speed of the adjusting plate 12, so as to ensure that the polishing wheel 4 does not stop working immediately and polish the tail end of the steel material well.

[0026] A second spring piece 22 is fixedly connected to the inner wall of the installation cavity 15. The second spring piece 22 is of an arc-shaped structure. The lower end of the second spring piece 22 is fixedly connected to a pressing plate 20. The pressing plate 20 is of a T-shaped structure. The lower end of the pressing plate 20 is of an arc-shaped structure. The lower end of the pressing plate 20 abuts against the control hook 144. When the rotating plate 141 enters the installation cavity 15, the upper end of the control hook 144 presses the pressing plate 20, thereby deforming the second spring piece 22 and pressing the counting button on the counter 21 to determine the number of steel polished, avoiding errors caused by manual counting.

[0027] Although the embodiments of the present invention have been shown and described, it should be emphasized that the above description is only an introduction and description of the usage mode of the embodiments of the present invention, and does not impose any formal limitation on the present invention. For those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
