Description

Technical Field

[0001] The present invention relates to the technical field of leveling equipment, and in particular to a cold-rolled strip leveling device. Background Art

[0002] In the production process of cold-rolled strips, due to factors such as rolling processes and collisions during transportation, the surface of cold-rolled strips is prone to uneven phenomena such as waves and bends. This not only affects the appearance quality of the products but also has an adverse impact on subsequent processing and use. Therefore, the leveling process of cold-rolled strips is crucial.

[0003] Most of the existing cold-rolled strip leveling devices have a single function and can only perform simple leveling operations. They lack functions such as cleaning, detecting, and automatically adjusting the leveling pressure of cold-rolled strips. During the leveling process, the dust and impurities remaining on the surface of cold-rolled strips will affect the leveling effect, and it is impossible to timely detect the unqualified leveling situation, nor can the leveling pressure be automatically adjusted according to the detection results, resulting in low leveling efficiency and quality, and it is difficult to meet the requirements of modern industrial production for high-quality and high-efficiency cold-rolled strips.

Two fixing plates 303 are fixedly installed on the rear inner wall of the L-shaped plate 102. A limiting seat 304 is fixedly installed on the top of the fixing plate 303. An adjusting plate 305 is slidably sleeved on the two limiting seats 304. A plurality of fixing springs 306 are fixedly installed on the bottom of the adjusting plate 305. The bottom ends of the corresponding fixing springs 306 are fixedly installed on the same U-shaped plate 308. An upper leveling roller 3013 is rotatably installed inside the U-shaped plate 308;

[0036] In this embodiment, sliding holes 309 are formed on the front and rear inner walls of the U-shaped plate 308. A sliding seat 3010 is slidably installed in the sliding hole 309. The same rotating shaft 3012 is rotatably installed between two corresponding sliding seats 3010, and the upper leveling roller 3013 is fixedly installed on the rotating shaft 3012.

[0037] In this embodiment, the detection mechanism includes a second U-shaped frame 501. A reciprocating lead screw 503 is rotatably installed on the inner walls of the front and rear sides of the second U-shaped frame 501.

[0039] In this embodiment, a driving motor 205 is fixedly installed on the front side of the first U-shaped frame 201, and the output shaft of the driving motor 205 is fixedly connected to the corresponding rotating shaft 202. The rear end of the rotating shaft 202 extends to the rear side of the first U-shaped frame 201 and is fixedly installed with a transmission gear 206, and the two transmission gears 206 are meshed with each other. The driving motor 205 drives the two rotating shafts 202 to rotate synchronously and reversely through the transmission gear 206, so that the cleaning sponge 204 on the rotating roller 203 can fully and efficiently clean the surface of the cold-rolled strip steel, improving the cleaning efficiency and effect and ensuring the smooth progress of the subsequent leveling process.

[0040] In this embodiment, dust suction covers 207 for removing dust from the cleaning sponge 204 are installed on the top of the first U-shaped frame 201 and the top of the workbench 101. A vacuum cleaner 208 connected to the dust suction cover 207 is installed on the top of the workbench 101, and the two rotating rollers 203 are located between the two dust suction covers 207. The combined use of the dust suction cover 207 and the vacuum cleaner 208 can timely suck away the dust and impurities adsorbed on the cleaning sponge 204, prevent the dust from adhering to the surface of the cold-rolled strip steel again, maintain the cleanliness of the cleaning sponge 204, and further continuously ensure the cleaning quality of the cold-rolled strip steel.

[0041] In this embodiment, belt pulleys 504 are installed at the rear ends of the rotating shaft 202 above the displacement and the reciprocating lead screw 503, and the same belt 505 is sleeved on the two belt pulleys 504. By using the transmission method of the belt pulleys 504 and the belt 505, the power transmission between the rotating shaft 202 and the reciprocating lead screw 503 is realized, enabling the cleaning mechanism 2 and the detection mechanism to work together, reducing the setting of additional power sources, and lowering the equipment cost and energy consumption.

T-shaped rods 307 are slidably installed in the guide holes, and the bottom ends of the T-shaped rods 307 are fixedly installed on the corresponding U-shaped plates 308. The cooperation between the guide holes and the T-shaped rods 307 provides a stable guiding effect for the movement of the adjusting plate 305, ensuring that the adjusting plate 305 will not shift during the movement, making the adjustment of the pressure on the upper straightening roller 3013 more accurate and stable, and improving the leveling effect of the cold-rolled strip steel.

[0043] In this embodiment, a control box 402 is fixedly installed on the top of the L-shaped plate 102, and a threaded rod 401 is fixedly installed on the top of the fixing plate 303.

Two driving bevel gears 405 are fixedly installed on the driving shaft 404, and the driving bevel gears 405 are engaged with the corresponding driven bevel gears 403. A rotary motor 406 is fixedly installed on one side of the control box 402, and the rotary motor 406 is fixedly connected with the driving shaft 404. By driving the driving shaft 404 and the driving bevel gears 405 to rotate through the rotary motor 406, the driven bevel gear 403 and the threaded rod 401 are driven to rotate, thereby realizing the up and down movement of the adjusting plate 305, accurately adjusting the pressure of the upper straightening roller 3013 on the cold-rolled strip steel, and enabling flexible adjustment according to different strip steel specifications and leveling requirements, improving the applicability and leveling quality of the equipment.

[0044] In this embodiment, the detection component 6 includes a connecting sleeve 601, a second pressure sensor 602, a connecting spring 603, and a detection head 604. A positioning mechanism is provided between the connecting sleeve 601 and the detection seat 502. The second pressure sensor 602 is fixedly installed on the inner wall of the top of the connecting sleeve 601. A connecting spring 603 is fixedly installed at the bottom of the second pressure sensor 602. The detection head 604 is slidably installed in the connecting sleeve 601, and the bottom end of the connecting spring 603 is fixedly installed on the detection head 604. This structural design of the detection component 6 enables the detection head 604 to always be in good contact with the surface of the cold-rolled strip under the elastic force of the connecting spring 603. When the flatness of the strip changes, the change in the position of the detection head 604 will cause a change in the pressure of the connecting spring 603 on the second pressure sensor 602, thereby accurately detecting the flatness of the strip and improving the sensitivity and accuracy of the detection.

[0045] In this embodiment, the positioning mechanism includes a T-shaped installation hole 701 and a T-shaped installation seat 702.

The T-shaped installation seat 702 is fixedly installed on the top of the connecting sleeve 601, and the T-shaped installation seat 702 is adapted to the corresponding T-shaped installation hole 701. The adaptation design of the T-shaped installation hole 701 and the T-shaped installation seat 702 enables the detection component 6 to be conveniently and accurately installed on the detection seat 502, while ensuring the stability of the installation, facilitating the replacement and maintenance of the detection component 6, and improving the operability and maintenance efficiency of the equipment.

[0046] In this embodiment, a plurality of fixing grooves 801 are formed at the bottom of the detection seat 502. A disassembly and assembly plate 802 is fixedly installed on one side of the connecting sleeve 601. A bolt hole 803 is formed at the top of the disassembly and assembly plate 802. A fixing bolt 804 adapted to the fixing groove 801 is installed in the bolt hole 803 in a threaded manner. Through the cooperation of the fixing bolt 804 and the fixing groove 801, the connection stability between the detection component 6 and the detection seat 502 is further enhanced, ensuring that the detection component 6 will not loosen during the working process, guaranteeing the accuracy and reliability of the detection results, and also facilitating the disassembly and replacement of the detection component 6 when needed.

[0047] In this embodiment, a programmable controller 105 is fixedly installed on the top of the workbench 101, and the drive motor 205, the rotating motor 406, the first pressure sensor 3011, the second pressure sensor 602, and the laser distance sensor 107 are all electrically connected to the programmable controller 105. The programmable controller 105 can centrally control and coordinate each component, and automatically control the operation of the drive motor 205 and the rotating motor 406 according to the data fed back by the pressure sensor and the laser distance sensor 107, realizing the automatic operation and precise adjustment of the equipment, improving the production efficiency and product quality, and reducing the errors and labor intensity of manual operation.

[0048] Working principle of the present invention: Pass the cold-rolled strip steel through between two rotating rollers 203, the upper straightening roller 3013 and the lower straightening roller 302. The fixing spring 306 can apply pressure to the U-shaped plate 308 and the upper straightening roller 3013, and the upper straightening roller 3013 can apply pressure to the cold-rolled strip steel. When the cold-rolled strip steel is conveyed, through the cooperation of the upper straightening roller 3013 and the lower straightening roller 302, the purpose of leveling the cold-rolled strip steel can be achieved. By starting the driving motor 205 and the vacuum cleaner 208, the driving motor 205 can drive the rotating shaft 202 and the rotating roller 203 to rotate. With the cooperation of the transmission gear 206, the two rotating rollers 203 can rotate synchronously and in opposite directions. The rotating roller 203 can clean the cold-rolled strip steel through the cleaning sponge 204, and the vacuum cleaner 208 can absorb the dust adhering to the cleaning sponge 204 through the dust suction cover 207, so as to achieve the purpose of cleaning the cold-rolled strip steel;

[0049] With the cooperation of the belt pulley 504 and the belt 505, the rotation of the rotating shaft 202 can drive the reciprocating screw rod 503 to rotate, and the reciprocating screw rod 503 can drive the detection seat 502 to move back and forth. The detection seat 502 drives the detection head 604 to move through the connecting sleeve 601. Under the elastic force of the connecting spring 603, the connecting spring 603 can push the detection head 604 to contact the cold-rolled strip steel. When the leveling of the cold-rolled strip steel is unqualified, at this time, the position of the detection head 604 in the vertical direction is displaced, and the pressure of the connecting spring 603 on the pressure sensor two 602 changes. By setting the laser ranging sensor 107, the accuracy of the detection of the cold-rolled strip steel can be improved. When the leveling is unqualified, the programmable controller 105 can start the rotating motor 406, and the rotating motor 406 can drive the driving shaft 404 and the driving bevel gear 405 to rotate. The driving bevel gear 405 can drive the threaded rod 401 to rotate through the driven bevel gear 403. The rotation of the threaded rod 401 can drive the adjusting plate 305 to move downward, and the adjusting plate 305 can squeeze the fixing spring 306. The fixing spring 306 can increase the pressure on the upper straightening roller 3013. The pressure sensor one 3011 can detect the pressure applied to the upper straightening roller 3013, so as to achieve precise adjustment of the applied force. By automatically adjusting the force applied to the upper straightening roller 3013, the purpose of accurately leveling the cold-rolled strip steel can be achieved.
