[0002] This invention relates to the field of cold-rolled strip steel production and processing. The production environment for cold-rolled strip steel is usually quite complex, and the strip steel needs to operate stably during conveying and shearing. Some existing conveying and clamping methods are poorly adaptable to this environment, cumbersome to operate, bulky, heavy, and difficult to maintain. This strip steel clamping and conveying device was designed to improve production operations.

[0003] Existing traditional strip clamping and conveying devices employ relatively heavy metal structures, resulting in a large overall weight. This not only requires large lifting equipment and a significant amount of manpower during installation, increasing installation costs and difficulty, but also lacks flexibility in equipment layout. Replacing a damaged clamping roller may require dismantling surrounding protective devices, transmission components, and other parts, with the entire repair process potentially taking several days, severely impacting normal production operations.

[0012] In some embodiments, the outer surfaces of the upper pinch roller and / or the lower pinch roller are provided with a wear-resistant layer.

[0013] In some embodiments, the third driving component is a pneumatic cylinder or a hydraulic cylinder; And / or, the output end of the second drive unit is connected to the lower pinch roller via a coupling.

Detailed Implementation

[0022] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4According to a first aspect of this application, a strip steel conveying device 100 is provided, including a support base 110, two spaced and parallel tracks 120, a traveling assembly 130, a clamping and conveying assembly 140, and a controller. The support base 110 includes a base 111 and two support frames 112 disposed above the base 111. The tracks 120 are angled to the strip steel conveying direction and are disposed below the base 111, with the base 111 slidably connected to the tracks 120. The traveling assembly 130 includes a first driving member 131, a gear 132, and a rack 133. The rack 133 is disposed between the two tracks 120 and is parallel to the tracks 120. The first driving member 131 is mounted on the base 111. The output end of 31 is connected to gear 132, and gear 132 meshes with rack 133; the clamping and conveying assembly 140 includes an upper clamping roller 141, a lower clamping roller 142, a second drive member 143, and two third drive members 144. The end of the upper clamping roller 141 is connected to the corresponding support frame 112 through a first bearing seat, and the output end of the third drive member 144 is connected to the corresponding first bearing seat to make the upper clamping roller 141 move up and down; the lower clamping roller 142 is connected to the support frame 112 through a second bearing seat, and the output end of the second drive member 143 is connected to the lower clamping roller 142 to make the lower clamping roller 142 rotate; the controller is connected to the first drive member 131, the second drive member 143, and the third drive member 144.

[0024] The first and second bearing housings can be made of high precision to ensure that the upper pinch roller 141 and the lower pinch roller 142 can rotate flexibly and with high concentricity. The first and second bearing housings are selected with good load-bearing capacity and sealing performance to prevent dust, impurities, etc. from entering the bearings and affecting their service life.

[0025] The walking assembly 130 uses a first driving element 131 to drive the meshing motion of gear 132 and rack 133, enabling the support base 110 to move on the track 120. The meshing transmission of gear 132 and rack 133 is stable, accurate, and less prone to failure. The meshing precision of gear 132 and rack 133 is high, ensuring a precise transmission ratio, typically reaching 0.1mm. Combined with high-precision gear 132 and rack 133 and high-quality assembly, this method of the first driving element 131 driving gear 132 and rack 133 results in a stable structure and high accuracy. When the first driving element 131 is activated by the controller, gear 132 on the support base 110 moves normally on the track 120 under the action of rack 133, allowing for accurate adjustment of the operating position and better maintenance and inspection of the device's condition.

[0026] The controller can be a PLC control system, which controls the entire operation process. The support frame is equipped with a slide groove, and the first bearing seat is slidably connected to the slide groove. The third drive component 144 drives the upper clamping roller 141 to move in the vertical direction and cooperates with the lower clamping roller 142 to clamp the strip. The second drive component 143 drives the lower clamping roller 142 to rotate, thereby driving the strip to move. The movement of the strip drives the upper clamping roller 141 to rotate, which can adapt to the conveying of strips of various specifications.

[0027] Therefore, this application, by setting up a walking component 130 and a clamping and conveying component 140, and driving the gear 132 and rack 133 to mesh via the first driving member 131, enables the support base 110 to move on the track 120. This allows the entire conveying device to be easily moved out of confined spaces for inspection and maintenance, facilitating repairs. Furthermore, compared to belt and chain drives, the gear 132 and rack 133 can effectively save energy, reducing maintenance and operating costs in the long term. The second driving member 143 and the third driving member 144 can clamp and convey the strip steel, ensuring its transport.

[0028] In some embodiments, the track 120 is perpendicular to the strip conveying direction. When maintenance is required, the entire conveying device can be moved out of the narrow space along the direction perpendicular to the strip conveying direction under the action of the first driving member 131, making maintenance convenient.

[0029] In some embodiments, the base 111 is equipped with four wheels, which roll in engagement with the track 120. The wheels can be constructed using specially treated steel, providing excellent wear resistance and corrosion resistance. The wheel diameter can be determined based on the device's travel speed and the vehicle's weight requirements; this application does not impose any special limitations. Two of the four wheels are located on one side, and the other two on the other side. Each wheel rolls in engagement with its corresponding track 120, ensuring the entire conveying device can move along the track 120, guaranteeing the accuracy of movement and preventing deviation.

[0030] In some embodiments, the axis of gear 132 is angled to the axis of the wheel. The axis of the wheel is horizontal, and the axis of gear 132 is vertical. Since gear 132 is horizontal, it does not need to support the entire support base 110, so its size can be smaller. In addition, since the axis of the horizontally positioned gear 132 is vertical, the output end of the first drive member 131 is also vertical, which facilitates installation.

[0031] In some embodiments, along the extension direction of the track 120, the first drive member 131 and the second drive member 143 are respectively located on opposite sides of the base 111. To avoid interference between the first drive member 131 and the second drive member 143 in the installation area, the first drive member 131 mainly acts on the rotation of the gear 132, and the second drive member 143 mainly acts on the rotation of the lower clamping roller 142. The first drive member 131 and the second drive member 143 are respectively located on opposite sides of the base 111, for example, the first drive member 131 is closer to the right side and the second drive member 143 is closer to the left side. This ensures the normal operation of the first drive member 131 and the second drive member 143, while also ensuring that the first drive member 131 and the second drive member 143 have their own installation space on the base 111, thus avoiding interference.

[0032] In some embodiments, the lengths of both the track 120 and the rack 133 are greater than twice the length of the base 111. In some embodiments, during normal strip conveying, the track 120 and the rack 133 are located at the center of the track 120. Due to the limited working space in the strip conveying area, if maintenance is required, the base 111 can be moved to the left or right by driving the first driving component 131. The base 111 can be moved away from the center of the track 120 by 1 / 3 to 1 / 2 of its length. If the cause of the overall fault can be detected by moving part of the base 111, then only part of it needs to be moved. If the cause of the overall fault can only be detected by moving the entire base 111, then the distance of moving the base 111 away from the center of the track 120 is one base 111 or more of its length.

[0033] In some embodiments, the upper pinch roller 141 is a hollow roller, and the lower pinch roller 142 is a solid roller. The upper pinch roller 141 moves up and down under the action of the third driving member 144. The hollow roller can reduce weight, thereby reducing the force of the third driving member 144 and ensuring the stability of strip pinching. The lower pinch roller 142 is a solid roller. During the frictional driving process between the lower pinch roller 142 and the strip, the solid roller can provide better support for the strip and ensure the stability of strip pinching.

[0034] In some embodiments, the outer surfaces of the upper pinch roller 141 and / or the lower pinch roller 142 are provided with a wear-resistant layer. The upper pinch roller 141 and the lower pinch roller 142 may be made of 45# steel, and the wear-resistant layer may be polyurethane rubber. Providing a wear-resistant layer on the outer surfaces of the upper pinch roller 141 and the lower pinch roller 142 can reduce the wear of the rollers on the surface of the strip steel.

[0035] In some embodiments, the diameter and length of the upper pinch roller 141 and the lower pinch roller 142 can be designed according to the strip width and conveying force requirements, enabling the conveying of strips with a width of 700~1300mm. This strip clamping and conveying device is designed with high flexibility and adjustability to better address the stable operation of strips on the production line, and can adapt to the clamping and conveying needs of strips of various specifications.

[0036] In some embodiments, the third drive member 144 is a pneumatic cylinder or a hydraulic cylinder. To achieve the clamping function during the strip conveying process, the upper clamping roller 141 is driven to move up and down by the pneumatic third drive member 144. The piston rod of the pneumatic cylinder is connected to the first bearing seat of the upper clamping roller 141. The pressure provided by the pneumatic cylinder allows the upper clamping roller 141 to press tightly against the lower clamping roller 142, thereby clamping the strip. In other embodiments, the third drive member 144 can be a hydraulic cylinder, as long as it can ensure that the upper clamping roller 141 and the lower clamping roller 142 cooperate to clamp the strip.

[0037] In other embodiments, the output end of the second drive member 143 is connected to the lower pinch roller 142 via a coupling 145. The second drive member 143 can be a variable frequency speed-regulating motor, with its power selected based on the conveying capacity of the device and the maximum weight of the strip. The second drive member 143 is lowered to a suitable range and then transmits power to the lower pinch roller 142 via the quincunx coupling 145, causing the pinch roller to rotate and thus conveying the strip. Starting the second drive member 143 causes the quincunx coupling 145 and the lower pinch roller 142 to rotate simultaneously, driving the cold-rolled strip to move forward normally on the support frame 112. Under the action of the third drive member 144, the upper pinch roller 141 presses the strip downwards, ensuring stable operation of the strip during clamping and conveying.

[0038] Thus, the third drive component 144 drives the upper clamping roller 141 to move vertically and cooperate with the lower clamping roller 142 to clamp the strip. The roller surface is made of polyurethane rubber material to reduce wear on the strip surface. The second drive component 143 drives the lower clamping roller 142 to rotate so that the strip can move forward normally. At the same time, when the cold rolling production line needs maintenance, the device can be moved off the production line by the first drive component 131 driving the gear 132 on the track 120 for disassembly and maintenance. This device improves the stability and efficiency of the operation.

[0039] This application includes a clamping and conveying assembly 140 and a traveling assembly 130. Traditional clamping structures mainly focus on clamping, resulting in low flexibility and practicality. The clamping and conveying assembly 140 of this application can ensure the normal conveying of the strip steel while maintaining clamping.

[0040] In a second aspect of this application, a strip steel conveying system is provided, comprising: one or more sets of the aforementioned strip steel clamping and conveying devices. The strip steel clamping and conveying devices can be arranged in one, two, or more sets depending on the production line conditions. The specific structure of the strip steel clamping and conveying device is as described in the above embodiments.

[0041] Therefore, the strip steel conveying device 100 of this application adopts a compact structural design, with a reasonable and close layout between various components, effectively reducing the overall footprint of the equipment. Compared with traditional large and bulky conveying equipment, this device has a significant advantage in space utilization. It can be flexibly installed and arranged in limited production spaces. This application has high flexibility and adjustability, and can adapt to the conveying needs of strip steel of various specifications. Regardless of the width, thickness, or material of the strip steel, it can be smoothly clamped and conveyed by simply adjusting the equipment parameters and component configuration. Through its compact and reasonable structural design, the new strip steel clamping and conveying device can achieve a greater clamping and conveying capacity in the same production area, improving space utilization and reducing the construction cost of the production workshop and the equipment footprint.

[0042] The strip conveying device 100 of this application is operated by a controller, which ensures that the cold-rolled strip is clamped between the upper clamping roller 141 and the lower clamping roller 142 by the third drive component 144. The second drive component 143 drives the lower clamping roller 142 to operate normally. The roller surface is made of polyurethane rubber material to reduce wear on the strip surface and protect the strip from scratches. This clamping and conveying method is not only fast, but also can achieve the clamping and positioning of the strip in a very short time, reducing the preparation time on the production line and improving production efficiency. Moreover, the clamping force is evenly distributed, avoiding deformation or damage to the strip due to excessive local force, and effectively ensuring the surface quality and internal structural integrity of the strip.
