Description

Technical Field

[0001] This utility model relates to the technical field of strip steel production equipment, specifically a combination device of dust removal brush roller and pressure roller for a hot rolling finishing unit uncoiler. Background Technology

[0002] The uncoiling equipment at the head of the finishing unit includes: a feeding trolley responsible for smoothly transferring the steel coil onto the uncoiling drum; an uncoiler responsible for supporting and tightening the steel coil and rotating it to release the material; an end support responsible for lifting the outermost end of the uncoiler drum; a straightening machine responsible for straightening the head of the steel strip to prevent bending and jamming; pressure rollers on the pressure arm responsible for pressing the outer edge of the steel coil to prevent it from uncoiling; and a support arm or guide plate that holds the head of the steel strip during uncoiling and guides it into the subsequent pinch rollers, where it completes subsequent straightening, leveling, slitting, and other processes.

[0003] With the increasing use of high-strength steel plates in hot-rolled finishing mills, the pressure requirements for the pressure arm to tighten the strip head and prevent loosening are constantly increasing (21MPa), exceeding the current maximum pressure (14MPa). With the increasing production of high-strength steel grades of 1200-1500MPa, wide plates of 2130mm, and thick plates of 5-6mm, some loose coils are inevitable. After the loose coils enter the uncoiler, the uncoiler needs to reverse and tighten the coils while the pressure arm presses them down. However, the rotating strip head generates a strong rebound impact when it leaves the pressure roller of the pressure arm, causing long-term damage to the strip head. The cement base of the impact pressing arm poses a safety hazard. Furthermore, while the reverse bending roller on the straightening machine can break up the iron oxide scale and collect dust on the surface of the bent strip, it cannot perform deep rust removal. As a result, residual rust, scale, and dust are pressed into the surface of the steel strip by subsequent pinch rollers and straightening machines. This is especially problematic for high-strength steel and for users with high surface quality requirements, who frequently complain about the surface quality and the high dust levels during the coil sizing process, which does not meet environmental protection requirements. Therefore, there is an urgent need for a dust removal brush roller and pressure roller combination device for the uncoiler of the hot rolling finishing unit to solve the above problems.

A dust removal box is fixedly connected to the top of the movable trolley.

[0010] The beneficial effects of this utility model are:

[0011] The hot-rolled finishing mill uses a combination of dust removal brush rollers and pressure rollers to uncoil the coiler. High-pressure pressure rollers are placed at the uncoiler of the hot-rolled finishing mill to tighten the high-strength steel coils on the uncoiler after they are loosened, while also overcoming the impact damage when the steel strip head leaves the pressure roller.

[0012] The hot-rolled finishing mill uses a combination of dust removal brush rollers and pressure rollers to uncoiler. Dust removal brush rollers are installed at the uncoiler to remove rust from the steel plate surface from the head, preventing rust and dust from being pressed into the steel strip surface during subsequent finishing processes and affecting the surface quality of the final steel plate product.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the dust removal brush roller module also includes a cylinder fixedly connected to the front of the fixed track, and the output end of the cylinder is fixedly connected to the moving trolley.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by driving the moving trolley along a fixed track with a cylinder, the brush roller can be quickly positioned and adjusted, thereby improving the automation level and working efficiency of the equipment.

A second pulley is fixedly connected to the outside of the brush roller. The end of the transmission belt away from the first pulley is fixedly connected to the second pulley.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the brush roller can be driven to rotate by a geared motor, which can achieve a high-efficiency dust removal effect. The belt drive method has a simple structure, runs smoothly, and can effectively reduce the noise and vibration of the equipment.

[0018] Furthermore, an arc-shaped baffle is fixedly connected to the side of the pressing arm near the pressing component, and an anti-collision polyurethane block is fixedly connected to the front of the overall base.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the arc-shaped baffle can significantly reduce the impact damage when the belt head is released from the pressure roller due to the short distance. The anti-collision polyurethane block can withstand the impact of the belt head and also reduce the noise of slapping, thus extending the service life of the equipment.

[0020] Furthermore, an air intake is fixedly connected to the front of the dust collection box, and a dust collection telescopic hose interface is fixedly connected to the back of the dust collection box. The end of the dust collection box near the brush roller is arranged in an arc shape below the brush roller.

[0021] The beneficial effects of adopting the above-mentioned further solution are that the air inlet can effectively collect the dust generated by the brush roller, keep the working environment clean, and the dust removal telescopic hose interface facilitates connection to an external dust removal system, further improving the dust removal effect.

[0022] Furthermore, there are two geared motors, and the pressing arm has a hollow structure located above the dust collector.

[0031] 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.

[0032] In the embodiments, by Figure 1-6 This invention provides a dust removal brush roller and pressure roller combination device for an uncoiler in a hot rolling finishing mill. The device includes an integral base 1, with an anti-impact baffle assembly module on top. The anti-impact baffle assembly module includes a pressure arm support 2 fixedly connected to the top of the integral base 1, a pressure arm 3 rotatably connected inside the pressure arm support 2, a pressure component 4 rotatably connected outside the pressure arm 3, and a pressure roller 5 rotatably connected inside the pressure component 4. A hydraulic cylinder base 6 is fixedly connected to the top of the integral base 1, and a hydraulic cylinder 7 rotatably connected to the front of the hydraulic cylinder base 6. The end of the hydraulic cylinder 7 away from the hydraulic cylinder base 6 is rotatably connected to the pressure arm 3. When the outer diameter of the steel coil changes due to continuous winding, the hydraulic cylinder 7 pushes the pressure arm 3 to rotate, thereby ensuring that the pressure roller 5 remains in contact with the steel coil.

[0033] In this embodiment, in actual use, an arc-shaped baffle 18 is fixedly connected to the side of the pressure arm 3 near the pressure component 4, and an anti-collision polyurethane block 19 is fixedly connected to the front of the overall base 1. A 20mm gap is left between the arc-shaped baffle 18 and the outer diameter edge of the steel coil. At the maximum coil diameter, after the strip head is released from the pressure roller 5, the impact acceleration is greatly reduced due to the short distance. In order to meet the needs of finishing a large amount of high-strength steel, the maximum working pressure of the hydraulic cylinder 7 is increased from 14MPa to 21MPa to meet the production needs of high-strength steel.

[0034] Specifically, refer to Figure 2 The top of the overall base 1 is equipped with a dust removal brush roller module. The dust removal brush roller module includes a fixed slide base 8 fixedly connected to the top of the overall base 1. A fixed track 9 is fixedly connected to the top of the fixed slide base 8. A moving trolley 10 is slidably connected inside the fixed track 9. A brush roller 11 is rotatably connected to the front of the moving trolley 10. The dust removal brush roller module also includes a cylinder 13 fixedly connected to the front of the fixed track 9. The output end of the cylinder 13 is fixedly connected to the moving trolley 10. The moving trolley 10 is driven to move along the fixed track 9 by the cylinder 13, which can realize the rapid positioning and adjustment of the brush roller 11, and improve the automation level and working efficiency of the equipment.

[0035] Specifically, refer to Figure 1 A mounting frame is fixedly connected to the top of the mobile trolley 10. The mounting frame is U-shaped. The cylinder 13 passes through the mounting frame and is fixedly connected to the mobile trolley 10. A reduction motor 14 is fixedly installed on the top of the mounting frame. A first pulley 15 is fixedly connected to the output shaft of the reduction motor 14. A transmission belt 16 is externally connected to the first pulley 15. A second pulley 17 is fixedly connected to the outside of the brush roller 11. The end of the transmission belt 16 away from the first pulley 15 is fixedly connected to the second pulley 17.

[0036] In this embodiment, in actual use, there are two geared motors 14. The pressure arm 3 has a hollow structure at a position above the dust collection box 12. The brush roller 11 is driven to rotate by the geared motor 14, which can achieve a high-efficiency dust removal effect. The belt drive method has a simple structure and runs smoothly, which can effectively reduce the noise and vibration of the equipment. The two geared motors 14 drive the same brush roller 11. The rotating brush roller 11 is close to the steel coil to start rust removal, achieving a high-efficiency rust removal effect. The hollow structure on the pressure arm 3 can reduce the weight of the equipment and facilitate the setting of the dust collection box 12.

[0037] It should be noted that the brush roller 11 is made of stainless steel wire or tungsten carbide coated steel wire. The selection of the diameter of the brush roller 11 should take into account the minimum roll diameter to avoid interference from the support protrusions at both ends of the winding machine drum. The selection of the length of the brush roller 11 should take into account the lateral movement interference of the uncoiler centering.

[0038] In this embodiment, in actual use, a dust collection box 12 is fixedly connected to the top of the mobile trolley 10. An air intake 20 is fixedly connected to the front of the dust collection box 12, and a dust collection telescopic hose interface 21 is fixedly connected to the back of the dust collection box 12. The end of the dust collection box 12 near the brush roller 11 is arc-shaped and positioned below the brush roller 11. The air intake 20 effectively collects the dust generated by the brush roller 11, maintaining a clean working environment. The dust collection telescopic hose interface 21 is used to connect to an external dust removal system, such as... The baghouse dust collector features a uniquely designed dust collection box 12. The air velocity at the suction inlet 20 reaches 24 m / s and is positioned below the brush roller 11. The dust collection box 12 is arc-shaped, enclosing the lower part of the brush roller 11 to prevent air leakage. The dust collection box 12 moves with the mobile trolley 10. The brush roller 11 rotates in the opposite direction to the steel coil. The downward kinetic energy of the brushed-off rust, scale, and dust, combined with the suction force of the suction inlet, prevents dust from overflowing and polluting the environment. The baghouse dust collector ensures compliant emissions while also guaranteeing no dust pollution on site.

[0039] Specifically, refer to Figure 4 The design structure of the overall base 1, which arranges the brush roller 11 and the pressure roller 5 on the overall base 1, can not only reduce the civil construction period, but also withstand the increased load of the pressure roller 5, meet the need for the pressure roller 5 to apply greater pressure. The anti-collision polyurethane block 19 can withstand the impact of the head and reduce the noise of the slapping, thus extending the service life of the equipment.
