Description

Technical Field

[0001] This utility model relates to the field of bulb flat steel processing technology, specifically to a high-efficiency device for cleaning oxide scale from the surface of bulb flat steel. Background Technology

[0002] Bulb flat steel is a type of steel with a specific shape and purpose. Surface oxide scale is an byproduct generated during the production process of bulb flat steel. Oxide scale makes the surface of bulb flat steel rough and affects its appearance quality. Therefore, special equipment is needed to remove the oxide scale from the surface of bulb flat steel.

[0003] For example, patent CN216731191U discloses a device for removing oxide scale from the surface of flat steel. This device includes conveying rollers. The flat steel is passed between two conveying rollers, and the conveying rollers are driven to move the flat steel to the right. As the flat steel moves to the right, a grinding mechanism grinds it, removing the oxide scale from its surface. This grinding mechanism ensures complete removal of the oxide scale, improving the removal effect and effectively avoiding the problem of incomplete oxide scale removal reducing the quality of flat steel production. However, when removing oxide scale from the surface of bulb flat steel, the cylindrical grinding rollers cannot effectively grind the protruding parts of the bulb flat steel due to the protrusion on one side, resulting in incomplete oxide scale removal.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing oxide scale removal devices for bulb flat steel surfaces. Utility Model Content

[0005] The purpose of this invention is to provide an efficient device for cleaning oxide scale on the surface of bulb flat steel, in order to solve the problem mentioned in the background art that when removing oxide scale from the surface of bulb flat steel, one side of the bulb flat steel will have a protrusion, and the cylindrical grinding roller is difficult to grind the protruding part of the bulb flat steel, resulting in incomplete removal of oxide scale from the surface of the bulb flat steel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency oxide scale removal device for bulb flat steel, comprising a cleaning box, conveying rollers rotatably connected to both sides inside the cleaning box, a drive module for driving the conveying rollers installed on one side of the cleaning box; a first drive motor installed on the other side of the cleaning box via a first bracket; two grinding rollers are arranged inside the cleaning box, and rotating shafts are fixedly connected inside the grinding rollers; one side of the rotating shaft is fixedly connected to the output end of the first drive motor; first synchronous pulleys are installed on the side of the two rotating shafts away from the first drive motor, and the two first synchronous pulleys are driven by a synchronous belt; a grinding mechanism for grinding the convex surface of the bulb flat steel is provided inside the cleaning box.

[0007] Furthermore, the grinding mechanism includes a sliding block slidably connected to the inside of one side of the cleaning box. A sliding frame is installed on one side of the sliding block, and a non-circular grinding head is threadedly connected to the other side of the sliding block via a threaded rod. A second bracket is installed on one side of the cleaning box, and a rotating column is rotatably connected inside the second bracket. A sector gear is fixedly connected to one end of the rotating column. Pulleys are installed on both the rotating column and the rotating shaft, and a belt is provided between the two pulleys. Racks that mesh with the sector gear are provided on the upper and lower sides inside the sliding frame.

[0008] Furthermore, the cleaning box is equipped with a cleaning mechanism for cleaning the oxide scale on the surface of the bulb flat steel.

[0009] Furthermore, the cleaning mechanism includes two reciprocating screws rotatably connected to the inside of the cleaning box. A second drive motor is mounted on one side of the cleaning box via a third bracket. The end of one reciprocating screw is fixedly connected to the output end of the second drive motor. A connecting plate is threadedly connected to the outer wall of one reciprocating screw. A first cleaning brush is disposed below the connecting plate. Scrapers are threadedly connected to both ends of the outer wall of the other reciprocating screw. A second cleaning brush is fixedly connected to the top of the two scrapers. Two guide rods are fixedly connected inside the cleaning box. The top of the connecting plate and the inside of the scrapers are slidably connected to the two guide rods, respectively.

[0010] Furthermore, a second synchronous pulley is fixedly connected to the outer wall of each of the two reciprocating screws, and a synchronous belt is provided between the two second synchronous pulleys.

[0011] Furthermore, a sliding column is slidably connected inside the connecting plate, and a spring is sleeved on the outer wall of the sliding column. The top end of the spring is fixedly connected to the connecting plate, and the bottom end of the spring is fixedly connected to the first cleaning brush.

[0012] Furthermore, cleaning grooves are provided on both sides of the bottom wall of the cleaning box, and a collection box is provided below the cleaning grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This high-efficiency oxide scale removal device for bulb flat steel uses a first drive motor to rotate a rotating shaft and grinding roller on one side. A first synchronous pulley and synchronous belt cause the other grinding roller to rotate synchronously, allowing both grinding rollers to simultaneously grind the bulb flat steel surface. This significantly improves the efficiency of oxide scale removal, enabling large-area surface cleaning in a short time. The rotating shaft, via pulleys and belts, drives a rotating column and sector gear, which in turn causes a sliding frame and sliding block to drive a shaped grinding head in reciprocating motion. This allows the shaped grinding head to flexibly reciprocate and grind according to the shape of the bulb flat steel's convex surface, adapting to the complex shape of the convex surface and effectively cleaning the oxide scale, thus improving the device's versatility and adaptability.

[0014] Furthermore, the second drive motor drives the reciprocating screw to rotate, causing the connecting plate, scraper, and cleaning brush to reciprocate, sweeping the oxide scale into the cleaning trough and into the collection box. This timely and comprehensive cleaning of the oxide scale generated during the cleaning process prevents it from accumulating in the cleaning box, ensuring a clean cleaning environment and also improving the cleaning quality of subsequent bulb flat steel.

[0015] Furthermore, the upper and lower surfaces of the bulb flat steel are cleaned by the cleaning brushes on both sides, ensuring that the oxide scale on the surface of the bulb flat steel can be completely removed. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-7 This utility model provides the following technical solution: a high-efficiency device for cleaning oxide scale on the surface of bulb flat steel, comprising a cleaning box 1, conveying rollers 2 rotatably connected to both sides inside the cleaning box 1, a drive module for driving the conveying rollers 2 installed on one side of the cleaning box 1; a first drive motor 4 installed on the other side of the cleaning box 1 via a first bracket; two grinding rollers 3 are arranged inside the cleaning box 1, and rotating shafts 5 are fixedly connected inside the grinding rollers 3; one side of the rotating shaft 5 is fixedly connected to the output end of the first drive motor 4; first synchronous pulleys 6 are installed on the side of the two rotating shafts 5 away from the first drive motor 4, and the two first synchronous pulleys 6 are driven by a synchronous belt; cleaning The interior of the box 1 is equipped with a grinding mechanism for grinding the convex surface of the ball flat steel. The grinding mechanism includes a sliding block 7, which is slidably connected to the interior of one side of the cleaning box 1. A sliding frame 8 is installed on one side of the sliding block 7, and a special-shaped grinding head 9 is threadedly connected to the other side of the sliding block 7 through a threaded rod. A second bracket is installed on one side of the cleaning box 1. A rotating column 11 is rotatably connected inside the second bracket. A sector gear 10 is fixedly connected to one end of the rotating column 11. Pulleys 12 are installed on both the rotating column 11 and the rotating shaft 5. A belt is provided between the two pulleys 12. Racks that mesh with the sector gear 10 are provided on the upper and lower sides inside the sliding frame 8.

[0026] In operation, the drive module is activated, providing power to the conveyor rollers 2, causing them to rotate. The flat steel ball is placed between the two conveyor rollers 2 and transported within the cleaning device, preparing it for subsequent scale removal. Then, the first drive motor 4 is activated, and its output rotates. Since one rotating shaft 5 is fixedly connected to the output of the first drive motor 4, it rotates along with the output, driving the fixed grinding roller 3 to rotate. Simultaneously, the first synchronous pulleys 6 on the two rotating shafts 5 drive the other rotating shaft 5 via a synchronous belt, causing it to rotate synchronously. When the flat steel ball passes the grinding roller 3 under the influence of the conveyor rollers 2, the rotating grinding roller 3 contacts the flat surface of the flat steel ball, and friction is used to clean the ball. The oxide scale on the steel surface is ground and cleaned. When the rotating shaft 5 rotates, since both the rotating column 11 and the rotating shaft 5 are equipped with pulleys 12, the rotating shaft 5 will drive one of the pulleys 12 to rotate. Through the transmission of the two pulleys 12 and the belt, the rotating column 11 will rotate. The rotation of the rotating column 11 will cause the sector gear 10 fixed to it to rotate as well. Since the upper and lower sides of the sliding frame 8 are provided with racks that mesh with the sector gear 10, when the sector gear 10 rotates, it will interact with the racks, thereby driving the sliding frame 8 to perform reciprocating linear motion. Since the sliding frame 8 is mounted on the sliding block 7, the sliding block 7 will slide back and forth inside the cleaning box 1 along with the sliding frame 8. During the sliding process, the sliding block 7 will drive the irregular grinding head 9 that is in contact with it to perform reciprocating motion. When the convex surface of the ball flat steel passes through the irregular grinding head 9, the reciprocating irregular grinding head 9 will efficiently grind and clean the oxide scale on the convex surface of the ball flat steel.

[0027] Example 2: Based on Example 1, a cleaning mechanism is also disclosed, the specific structure of which is as follows: The cleaning mechanism includes two reciprocating screws 15, which are rotatably connected to the inside of the cleaning box 1. A second drive motor 13 is mounted on one side of the cleaning box 1 via a third bracket. The end of one reciprocating screw 15 is fixedly connected to the output end of the second drive motor 13. A connecting plate 18 is threadedly connected to the outer wall of one reciprocating screw 15, and a first cleaning brush 16 is disposed below the connecting plate 18. Scrapers 20 are threadedly connected to both ends of the outer wall of the other reciprocating screw 15, and a second cleaning brush 17 is fixedly connected to the top of the two scrapers 20. The inside of the cleaning box 1 is fixedly connected to... Two guide rods 19 are connected, and the top of the connecting plate 18 and the inside of the scraper 20 are slidably connected to the two guide rods 19 respectively; the outer walls of the two reciprocating screws 15 are fixedly connected to the second synchronous pulleys 14, and a synchronous belt is provided between the two second synchronous pulleys 14; a sliding column 21 is slidably connected inside the connecting plate 18, and a spring 22 is sleeved on the outer wall of the sliding column 21. The top end of the spring 22 is fixedly connected to the connecting plate 18, and the bottom end of the spring 22 is fixedly connected to the first cleaning brush 16; cleaning grooves are opened on both sides of the bottom wall of the cleaning box 1, and a collection box 23 is provided below the cleaning grooves.

[0028] By starting the second drive motor 13, its output drives the reciprocating screw 15 connected to it to rotate. Since the second synchronous pulleys 14 on the two reciprocating screws 15 are driven by a synchronous belt, the other reciprocating screw 15 will rotate synchronously. When the reciprocating screw 15 on the connecting plate 18 rotates, it will drive the connecting plate 18, which is threadedly connected to the reciprocating screw 15, to move back and forth under the guidance of the guide rod 19. The reciprocating motion of the connecting plate 18 drives the first cleaning brush 16 below to move together, thereby cleaning the oxide scale in the cleaning box 1. During the cleaning process, the spring 22 allows the first cleaning brush 16 to float up and down within a certain range, ensuring that the first cleaning brush 16 always makes full contact with the bottom surface of the cleaning box 1, thus improving the cleaning effect. When it contacts the convex surface of the bulb flat steel, the first cleaning brush 16 is squeezed, causing the sliding column 21 to move upward, thereby squeezing the spring 22. This allows the first cleaning brush 16 to adapt to different convex surfaces of the bulb flat steel. When the reciprocating screw 15 on the second cleaning brush 17 rotates, the scraper 20, guided by the guide rod 19, moves reciprocally along the reciprocating screw 15. The reciprocating motion of the scraper 20 drives the second cleaning brush 17 at the top to move together, further cleaning the oxide scale in the cleaning box 1. The scraper 20 can push the oxide scale into the cleaning groove set inside the cleaning box, facilitating subsequent cleaning. Since the cleaning groove is connected to the collection box 23, the oxide scale will fall into the collection box 23 along the cleaning groove, achieving centralized collection of oxide scale for convenient subsequent processing.
