Description

Technical Field

[0001] This utility model relates to the field of cold-rolled strip steel processing, and in particular to an automatic leveling device for stamping cold-rolled strip steel. Background Technology

[0002] Cold-rolled steel strip has excellent properties. Through cold rolling, thinner and more precise cold-rolled steel strips and plates can be obtained. It has high flatness, high surface smoothness, and the surface of cold-rolled plates is clean and smooth, easy to coat and plate. It has a wide variety of types and applications. In the production process of cold-rolled steel strip, leveling is required.

[0003] However, existing leveling devices are prone to generating debris during the leveling process, and the high speed of the debris makes it difficult to collect, reducing the quality of the working environment. In addition, existing cold-rolled strip steel is usually coiled and placed, which is inconvenient to install when it is put into leveling. Furthermore, when polishing the surface, multiple motors are required to drive the polishing to ensure thorough grinding, resulting in high operating costs. Therefore, we propose an automatic leveling device for stamping cold-rolled strip steel. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic leveling device for stamping cold-rolled strip steel. This device achieves efficient automatic leveling of the cold-rolled strip steel while effectively collecting the debris generated during the leveling process, solving the problems of difficult debris collection and negative impact on the working environment quality of existing devices. Another purpose of this utility model is to provide an automatic leveling device for stamping cold-rolled strip steel. This device not only facilitates the loading and installation of coiled cold-rolled strip steel, reducing the operational difficulty during loading, but also, through optimized polishing drive structure, achieves comprehensive polishing of the cold-rolled strip steel surface without the need for multiple motors, reducing the number of motors used and lowering the operating cost of the device.

[0005] Technical solution: An automatic leveling device for stamping cold-rolled strip steel, including an installation mechanism, wherein the installation mechanism includes a base plate, and an installation platform is fixedly connected to the right side of the upper surface of the base plate;

[0006] A dispensing mechanism is provided on the left side of the upper surface of the installation mechanism;

[0007] A leveling mechanism is provided at the center of the upper surface of the installation mechanism;

[0008] A polishing collection mechanism is provided on the right side of the upper surface of the installation mechanism;

[0009] The dispensing mechanism includes a fixed plate, the bottom of which is fixedly connected to the upper left rear of the base plate. A rotating rod is rotatably connected to the right side of the front surface of the fixed plate via a rotating shaft. A spiral groove is provided on the front of the outer side wall of the rotating rod. A movable plate is slidably connected to the outer side wall of the rotating rod. A connector is fixedly connected to the rear surface of the movable plate. A connecting column is fixedly connected to the lower surface of the connector and located inside the spiral groove.

[0010] Both the fixed plate and the movable plate have delivery ports on opposite sides. The inner side of each delivery port is rotatably connected to a receiving plate via a rotating shaft. A motor is fixedly connected to the rear surface of the fixed plate. The front end of the output shaft of the motor is fixedly connected to the rear end of the central shaft of the receiving plate located behind the upper surface of the base plate.

[0011] Furthermore, the lower surface of the base plate is fixedly connected with multiple casters.

[0012] Furthermore, a guide rod is fixedly connected to the left side of the front surface of the fixed plate, and the front end of the guide rod extends through to the front of the movable plate and is slidably connected to the movable plate.

[0013] Furthermore, a disc is fixedly connected to the front end of the rotating rod, and a spring is fixedly connected to the disc and the movable plate opposite to and outside the rotating rod.

[0014] Furthermore, a transmission wheel is fixedly connected to the outer wall of the output shaft of the motor, and a transmission belt is provided on the outer wall of the transmission wheel.

[0015] Furthermore, the leveling mechanism includes two mounting plates 1, and mounting plates 2 are provided on the left side of each of the two mounting plates 1. Two leveling rollers 1 are rotatably connected between the two mounting plates 1 via a rotating shaft. A transmission wheel 2 is fixedly connected to the front end of the central shaft of each leveling roller 1. The transmission wheel 2, located below the front surface of the mounting plate 1, is located inside the transmission belt 1 and is connected to the transmission belt 1. Two leveling rollers 2 are rotatably connected between the two mounting plates 2 via a rotating shaft. Gears 1 are fixedly connected to the rear ends of the central shafts of the two leveling rollers 2 and the rear ends of the central shafts of the two leveling rollers 1. The two gears 1, which are vertically opposite each other, are meshed together. A transmission wheel 3 is fixedly connected to the front end of the central shaft of the leveling roller 2 located above the inner side of the two mounting plates 2. The transmission wheel 3 and the outer side wall of the transmission wheel 2 located above the front surface of the mounting plate 1 are connected to the transmission belt 2. The bottom of the mounting plate 1 and the bottom of the mounting plate 2 are both fixedly connected to the upper surface of the mounting platform.

[0016] Furthermore, the polishing collection mechanism includes a box body, the bottom of which is fixedly connected to the upper surface of the mounting platform. Both the front and rear surfaces of the box body have material inlets. A second motor is connected to the upper surface of the box body. A second gear is fixedly connected to the bottom end of the output shaft of the second motor. Two third gears are meshed with the outer side walls of the second gear, and a fourth gear is meshed with the outer side walls of the third gears. The bottoms of the third gear and the fourth gear are rotatably connected to the upper surface of the box body via rotating shafts. The bottom ends of the central shafts of the second gear and the fourth gear both penetrate into the interior of the box body and are fixedly connected to polishing wheels.

[0017] Furthermore, a collection box is slidably installed inside the box, a cover plate is fixedly connected to the front surface of the collection box, and a handle is fixedly connected to the front surface of the cover plate.

[0018] Beneficial effects: The feeding mechanism uses the mechanical cooperation of "rotating rod-spiral groove-connecting column" and the return function of spring to realize the convenient opening and closing of the movable plate: the operator only needs to hold the disc and rotate the rotating rod to open the gap between the movable plate and the fixed plate, and easily put in the cold-rolled strip steel coil; after releasing the disc, the spring can push the movable plate to automatically return to its original position, and cooperate with the abutment plate to complete the coil clamping.

[0019] Compared to the existing devices that require multiple people to coordinate and adjust during deployment, this design greatly simplifies the deployment process, allowing a single person to complete the operation, thus reducing the labor intensity and time cost of strip steel deployment.

[0020] The device establishes a "feed-leveling" power linkage system through motor one: while driving the strip to unwind, motor one transmits power to the leveling mechanism via transmission wheel one and transmission belt one; within the leveling mechanism, transmission belt one drives the lower leveling roller one to rotate, and then through the meshing transmission of gear one, the upper and lower leveling rollers one rotate in opposite directions (preliminary leveling), while the upper leveling roller one drives the leveling roller two to rotate via transmission belt two and transmission wheel three (secondary fine leveling). This "single motor driving multiple roller linkage" design avoids the problem of poor synchronization of multiple motors, ensuring that the cold-rolled strip remains horizontal throughout the transmission process, and through the dual treatment of "preliminary leveling + fine leveling," effectively guarantees the straightness of the strip, meeting the high precision requirements of the stamping process.

[0021] To address the pain point of existing devices that suffer from "multi-motor driven polishing and high cost," the polishing collection mechanism adopts a "gear transmission + single motor drive" design: Motor 2 only needs to drive Gear 2 to rotate, which in turn, through the meshing of Gear 2 and Gear 3, and Gear 3 and Gear 4, synchronously drives the three polishing wheels to rotate (corresponding to the upper surface and two sides of the strip steel, respectively). Compared to the traditional "one polishing wheel with one motor" solution, this design reduces the use of multiple motors, thereby lowering not only the purchase cost of the device but also the energy consumption and subsequent maintenance costs of the motors, balancing comprehensive polishing with economic efficiency.

[0022] The polishing collection mechanism achieves closed-loop debris collection through a "box + collection box + cover" structure: debris generated during polishing falls into the collection box inside the box due to gravity, and the cover effectively prevents debris from escaping from the front surface of the box; when debris accumulates to a certain amount, the operator can easily pull out the collection box for cleaning using the handle, making operation convenient. This design solves the problems of "scratching debris and difficulty in collection" in existing devices, preventing debris from contaminating the surface of cold-rolled strip steel or affecting the health of operators, significantly improving the quality of the working environment on the production site, and reducing the workload of environmental cleaning.

Detailed Implementation

[0030] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example

[0032] like Figure 1 and Figure 2 As shown, an automatic leveling device for stamping cold-rolled strip steel is provided, including a mounting mechanism 1. The mounting mechanism 1 includes a base plate 101, and a mounting platform 102 is fixedly connected to the right side of the upper surface of the base plate 101.

[0033] Multiple casters 103 are fixedly connected to the lower surface of the base plate 101;

[0034] The base plate 101 serves as the basic load-bearing component of the device. Its horizontal structure ensures the stable installation of components such as the mounting platform 102 and the delivery mechanism 2. The mounting platform 102 is fixed to the base plate 101, providing a height-adapted mounting platform for the leveling mechanism 3 and the polishing and collecting mechanism 4, meeting the horizontal height requirements of the cold-rolled strip during the transmission process. Multiple casters 103 are evenly distributed at the four corners of the lower surface of the base plate 101. Each caster 103 is equipped with a brake pad, which facilitates the operator to push the device to adjust its position according to the needs of the production site, and can also be fixed by the brake pad when the device is working, avoiding the impact of device displacement on the leveling accuracy of the cold-rolled strip.

[0035] like Figure 3 As shown, a dispensing mechanism 2 is provided on the left side of the upper surface of the installation mechanism 1;

[0036] The dispensing mechanism 2 includes a fixed plate 201. The bottom of the fixed plate 201 is fixedly connected to the upper surface of the base plate 101 at the left rear. A rotating rod 202 is rotatably connected to the right side of the front surface of the fixed plate 201 via a rotating shaft. A spiral groove 203 is provided on the front of the outer side wall of the rotating rod 202. A movable plate 204 is slidably connected to the outer side wall of the rotating rod 202. A connector 205 is fixedly connected to the rear surface of the movable plate 204. A connecting column 206 is fixedly connected to the lower surface of the connector 205 and located inside the spiral groove 203.

[0037] Both the fixed plate 201 and the movable plate 204 have a feeding port 207 on opposite sides. The inner side of the feeding port 207 is rotatably connected to the abutment plate 208 via a rotating shaft. The rear surface of the fixed plate 201 is fixedly connected to a motor 209. The front end of the output shaft of the motor 209 is fixedly connected to the rear end of the central shaft of the abutment plate 208 located behind the upper surface of the base plate 101.

[0038] A guide rod 210 is fixedly connected to the left side of the front surface of the fixed plate 201. The front end of the guide rod 210 extends through to the front of the movable plate 204 and is slidably connected to the movable plate 204.

[0039] A disc 211 is fixedly connected to the front end of the rotating rod 202. A spring 212 is fixedly connected to the disc 211 and the movable plate 204 at the opposite position and on the outside of the rotating rod 202.

[0040] A transmission wheel 213 is fixedly connected to the outer wall of the output shaft of motor 209, and a transmission belt 214 is provided on the outer wall of the transmission wheel 213.

[0041] The guide rod 210 adopts a smooth cylindrical rod body, and its sliding cooperation with the movable plate 204 can limit the movement direction of the movable plate 204, ensuring that the movable plate 204 can only move smoothly in the front and back direction.

[0042] When it is necessary to feed the cold-rolled strip steel coil, the rotating rod 202 is driven to rotate by the hand-held disc 211. With the cooperation of the spiral groove 203, the connector 205 and the connecting column 206, the movable plate 204 can move away from the designated functional plate 201, opening up the distance between the two, so that the cold-rolled strip steel coil can be fed between them. After releasing the disc 211, the movable plate 204 moves back to the fixed plate 201 under the push of the spring 212, and the two abutment plates 208 complete the clamping of the cold-rolled strip steel coil. At this time, the motor 209 is started to unwind the cold-rolled strip steel coil.

[0043] At the same time, the output shaft of motor 209 drives the transmission wheel 213 to rotate, and the transmission wheel 213 provides power to the leveling mechanism 3 through the transmission belt 214, realizing the power linkage between placement and leveling.

[0044] like Figure 4As shown, a leveling mechanism 3 is provided at the center of the upper surface of the mounting mechanism 1;

[0045] The leveling mechanism 3 includes two mounting plates 301, and a mounting plate 302 is provided on the left side of each mounting plate 301. Two leveling rollers 303 are rotatably connected between the two mounting plates 301 via a rotating shaft. A transmission wheel 304 is fixedly connected to the front end of the central shaft of each leveling roller 303. The transmission wheel 304, located below the front surface of the mounting plate 301, is situated inside the transmission belt 214 and is connected to the transmission belt 214. Two leveling rollers 305 are rotatably connected between the two mounting plates 302 via a rotating shaft. The two leveling rollers 305 are shown in the figure. Gear 306 is fixedly connected to the rear end of the central shaft of 305 and the rear end of the central shaft of the two leveling rollers 303. The two gears 306 mesh with each other. The front end of the central shaft of the leveling roller 305 located above the inner side of the two mounting plates 302 is fixedly connected to the transmission wheel 307. The transmission wheel 307 and the outer side wall of the transmission wheel 304 located above the front surface of the mounting plate 301 are connected to the transmission belt 308. The bottom of the mounting plate 301 and the bottom of the mounting plate 302 are fixedly connected to the upper surface of the mounting platform 102.

[0046] Two leveling rollers 303 are arranged parallel to each other, with their outer walls made of high-hardness, wear-resistant material and a surface smoothness that meets the leveling requirements of cold-rolled strip steel. When the transmission belt 214 drives the lower transmission wheel 304 to rotate, the lower leveling roller 303 rotates synchronously. The gear 306 at the rear end of the lower leveling roller 303 drives the gear 306 at the rear end of the upper leveling roller 303 to rotate in the opposite direction, thus achieving the opposing rotation of the two leveling rollers 303 and performing preliminary leveling of the incoming cold-rolled strip steel; the transmission wheel 304 at the front end of the upper leveling roller 303... 304 drives the transmission wheel 307 to rotate via the transmission belt 2 308. The transmission wheel 307 drives the upper leveling roller 2 305 to rotate. The gear 1 306 at the rear end of the upper leveling roller 2 305 drives the gear 1 306 at the rear end of the lower leveling roller 2 305 to rotate in the opposite direction, realizing the opposite rotation of the two leveling rollers 2 305. The spacing of the leveling rollers 2 305 is slightly smaller than the spacing of the leveling rollers 1 303. The cold-rolled strip is then finely leveled a second time to ensure that the flatness of the cold-rolled strip meets the stamping requirements and to ensure the horizontality of the strip transmission during the leveling process.

[0047] like Figure 5 and Figure 6 As shown, a polishing collection mechanism 4 is provided on the right side of the upper surface of the mounting mechanism 1;

[0048] The polishing collection mechanism 4 includes a housing 401. The bottom of the housing 401 is fixedly connected to the upper surface of the mounting platform 102. The front and rear surfaces of the housing 401 are provided with material inlets 402. The upper surface of the housing 401 is connected to a second motor 403. The bottom end of the output shaft of the second motor 403 is fixedly connected to a second gear 404. The outer side wall of the second gear 404 is meshed with two third gears 405. The outer side wall of the third gear 405 is meshed with a fourth gear 406. The bottom of the third gear 405 and the bottom of the fourth gear 406 are rotatably connected to the upper surface of the housing 401 through a rotating shaft. The bottom end of the central shaft of the second gear 404 and the bottom end of the central shaft of the fourth gear 406 both penetrate into the interior of the housing 401 and are fixedly connected to a polishing wheel 407.

[0049] A collection box 408 is slidably installed inside the box 401. A cover plate 409 is fixedly connected to the front surface of the collection box 408. A handle 410 is fixedly connected to the front surface of the cover plate 409.

[0050] The size of the feed inlet 402 is adapted to the width of the cold-rolled strip steel, ensuring that the leveled cold-rolled strip steel can smoothly enter the box 401. After starting the second motor 403, the output shaft of the second motor 403 drives the second gear 404 to rotate. The second gear 404 simultaneously drives the two meshing third gears 405 to rotate. The two third gears 405 respectively drive the corresponding fourth gears 406 to rotate, thereby realizing that one second motor 403 synchronously drives the three polishing wheels 407 to rotate, achieving comprehensive polishing of the strip steel surface without the need for multiple motors, greatly reducing the cost of use. The debris generated during the polishing process falls into the collection box 408 under the action of gravity. When the debris in the collection box 408 accumulates to a certain amount, the operator can pull the handle 410 to pull the collection box 408 out of the box 401, pour out the debris, and then push the collection box 408 back to its original position. The cover plate 409 can prevent debris from escaping from the front surface of the box 401, ensuring a clean working environment and solving the problem of difficult debris collection in existing devices.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
