Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, and in particular to a conveying device for cutting ultra-thick sheets. Background Technology

[0002] Ultra-thick plates (usually referring to metal plates with a thickness of 50mm and above) are widely used in heavy industries such as engineering machinery, shipbuilding, and pressure vessels. The precision and efficiency of their cutting and processing directly determine the quality of the final products.

[0003] Currently, ultra-thick plate conveying devices on the market generally suffer from the following technical defects: First, the reliability of centering and positioning is poor. Most devices only form a fixed-width channel through parallel guide rods. When ultra-thick plates are fed, they are prone to shifting due to uneven weight distribution or initial placement deviation, requiring manual correction. Second, the adaptability of specifications is insufficient. When conveying plates of different widths, it is necessary to disassemble and replace the guide components or manually adjust the channel spacing through multiple bolts, which cannot meet the needs of rapid switching of multiple specifications of plates in mass production.

[0004] Therefore, those skilled in the art urgently need to develop a conveying device for cutting ultra-thick plates. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a conveying device for cutting ultra-thick plates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a conveying device for cutting ultra-thick plates, comprising a conveyor belt, wherein U-shaped supports are symmetrically provided on both sides of the conveyor belt, and side plates are fixedly provided on adjacent sides of the two U-shaped supports, and a first conveying channel and a second conveying channel are sequentially provided on adjacent sides of the two side plates along the conveying direction of the conveyor belt. The first conveying channel is composed of two sets of symmetrically arranged fixed rods. The two sets of fixed rods are arranged in parallel between two side plates. One end of each set of fixed rods is fixedly connected to the side plate on the adjacent side. The length of the fixed rods increases gradually along the conveying direction of the conveyor belt, and the side of each set of fixed rods away from the side plate is rotatably equipped with guide wheels. The second conveying channel consists of two sets of symmetrically arranged moving rods, which are arranged in parallel between two side plates. Each set of moving rods has the same length, and each set of moving rods is rotatably equipped with guide wheels on adjacent sides. Each set of moving rods is connected to the adjacent side plate by a telescopic component. Along the conveyor belt conveying direction, the channel width formed by the guide wheels on both sides of the first conveying channel decreases in a gradient manner, while the channel width formed by the guide wheels on both sides of the second conveying channel remains constant; and the channel widths formed by the guide wheels on both sides at the adjacent ends of the first and second conveying channels are matched.

[0007] Preferably, the telescopic assembly includes a spring, one end of which is connected to an adjacent side plate, and the other end of which is connected to a moving rod via a support plate.

[0008] Preferably, the spring has a guide assembly inside, the guide assembly including a guide sleeve and a guide post that are adapted to each other, and the guide sleeve and the guide post are slidably engaged along the axial direction.

[0009] Preferably, the conveyor belt has a base plate on both sides of its bottom, two sets of guide rods are fixedly arranged in parallel between the two base plates, and two sets of lead screws are rotatably mounted in parallel. The threads on the two sets of lead screws are arranged symmetrically in opposite directions. Two adjusting plates are symmetrically arranged between the two base plates. Each adjusting plate is threadedly connected to the two sets of lead screws and slidably connected to the two sets of guide rods. The upper part of the two adjusting plates is fixedly connected to the bottom of the adjacent U-shaped support.

[0010] Preferably, each of the two sets of guide rods is symmetrically fitted with a limiting ring, which is fixedly assembled on the guide rod and located between the two adjusting plates.

[0011] Preferably, a drive motor is provided on the left base plate, and the output end of the drive motor is coaxially and fixedly connected to one of the lead screws. The right ends of both sets of lead screws extend out of the right base plate and are respectively fixedly fitted with pulleys. The two pulleys are connected by belt drive.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The first conveying channel uses a gradient-increasing fixed rod design to create a gradual channel for the guide wheels. After the ultra-thick plate enters, it can be automatically corrected for deviation and achieve initial centering. The guide wheels of the second conveying channel fit tightly with the plate, further enhancing positioning accuracy, effectively reducing positioning errors before cutting, and improving cutting quality.

[0013] 2. The guide assembly provides precise guidance for the spring extension and retraction, preventing radial deviation of the spring; the limit ring restricts the movement range of the adjustment plate to prevent structural collisions; the servo motor drives the lead screw to achieve rapid adjustment of the channel width, eliminating the need for manual operation, reducing labor intensity, and improving production efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figures 1-6 This utility model provides an embodiment: a conveying device for cutting ultra-thick plates, including a conveyor belt 1, U-shaped supports 2 symmetrically arranged on both sides of the conveyor belt 1, and side plates 3 fixedly arranged on the adjacent sides of the two U-shaped supports 2. The side plates 3 are arranged laterally along the conveying direction of the conveyor belt 1, and a first conveying channel and a second conveying channel are arranged sequentially on the adjacent sides of the two side plates 3 along the conveying direction of the conveyor belt 1.

[0020] The first conveying channel, serving as the plate feeding and centering mechanism, consists of two sets of symmetrically arranged fixed rods 4. The two sets of fixed rods 4 are parallel to each other between two side plates 3. Each set of fixed rods 4 includes 3-5 rods distributed at equal intervals. One end of each set of fixed rods 4 is fixedly connected to the adjacent side plate 3. The length of the fixed rods 4 increases gradually along the conveying direction of the conveyor belt 1, and guide wheels 5 are rotatably mounted on the side of each set of fixed rods 4 away from the side plate 3. The width of the channel formed by the guide wheels 5 on both sides of the first conveying channel decreases gradually from the feeding end, and the width at the end is consistent with the width of the second conveying channel, thereby realizing automatic centering and correction of the plate.

[0021] The second conveying channel, as a stable conveying mechanism, consists of two sets of symmetrically arranged moving rods 6. The two sets of moving rods 6 are arranged in parallel between the two side plates 3. Each set of moving rods 6 contains the same number of rods as the first conveying channel, and the length of each rod is uniform. Each set of moving rods 6 is rotatably equipped with guide wheels 5 on adjacent sides. Each set of moving rods 6 is connected to the adjacent side plate 3 by a telescopic component 7.

[0022] Along the conveying direction of conveyor belt 1, the channel width formed by the guide wheels 5 on both sides of the first conveying channel decreases in a gradient manner, while the channel width formed by the guide wheels 5 on both sides of the second conveying channel remains constant; and the channel widths formed by the guide wheels 5 at the adjacent ends of the first and second conveying channels are matched.

[0023] The center of the guide wheel 5 is recessed, and the curvature of the recess matches the edge contour of the ultra-thick plate, which can form a wrap-around limit.

[0024] The telescopic component 7 provides adaptive adjustment capability for the channel width. Specifically, it includes a spring 9, which is a high-strength compression spring. One end of the spring 9 is fixedly connected to the adjacent side plate 3 by welding, and the other end of the spring 9 is connected to the moving rod 6 through a support plate 8. The support plate 8 is made of stamped steel plate and is fixed to the moving rod 6 by bolts to enhance the connection strength.

[0025] To prevent radial displacement during the extension and retraction of spring 9, a guide assembly is installed inside spring 9. The guide assembly includes a guide sleeve and a guide post that are adapted to each other. Both the guide sleeve and the guide post are made of 45 steel. The inner diameter of the guide sleeve and the outer diameter of the guide post are fitted with a clearance to ensure that the guide sleeve and the guide post slide stably along the axial direction, providing precise guidance for the extension and retraction of the spring.

[0026] To accommodate the conveying needs of ultra-thick plates of different specifications, base plates 10 are installed on both sides of the bottom of the conveyor belt 1, which are fixed to the ground with expansion bolts to improve the overall stability of the device. Two sets of guide rods 12 are fixed in parallel between the two base plates 10, and two sets of lead screws 13 are mounted in parallel and rotate in parallel. The lead screws 13 are trapezoidal threaded lead screws, and the threads on the two sets of lead screws 13 are arranged symmetrically and in opposite directions to realize the synchronous and opposite movement of the two adjusting plates.

[0027] Two adjusting plates 11 are symmetrically arranged between the two base plates 10. Each adjusting plate 11 is threaded to two sets of lead screws 13 through a nut and slidably connected to two sets of guide rods 12 through a linear bearing. The upper part of the two adjusting plates 11 is fixedly connected to the bottom of the adjacent U-shaped support 2 by bolts to realize the synchronous movement of the U-shaped support and the adjusting plate.

[0028] To limit the movement range of the adjusting plate 11 and avoid structural collisions, limiting rings 14 are symmetrically fitted on both sets of guide rods 12. They are fixedly assembled on the guide rods 12 by set screws and located between the two adjusting plates 11. The position of the limiting rings can be adjusted according to the specifications of commonly used sheet materials.

[0029] The drive component of the device is located on the left base plate 10, specifically a drive motor 15. The drive motor 15 is a servo motor, and its output end is coaxially and fixedly connected to one of the lead screws 13 via a coupling. The right ends of both sets of lead screws 13 extend out of the right base plate 10 and are respectively fixedly fitted with pulleys via key connections. The two pulleys are of the same specification and are connected by a synchronous belt 16 to achieve synchronous rotation of the two sets of lead screws, ensuring the consistency of the movement of the adjusting plate.

[0030] Working principle of this utility model: 1. Based on the width specifications of the extra-thick plate to be conveyed, start the drive motor 15. The output of the drive motor drives the lead screw 13 connected to it to rotate. This lead screw drives another set of lead screws to rotate synchronously through the transmission action of the pulley and the synchronous belt 16. Since the threads on the two sets of lead screws 13 are arranged symmetrically in opposite directions, the two adjusting plates 11 connected to the lead screw threads move synchronously in opposite directions along the guide rod 12, thereby driving the U-shaped support 2, side plate 3 and conveying channel fixedly connected to the adjusting plates to move as a whole until the width of the tail of the first conveying channel is slightly larger than the width of the plate. After the adjustment is completed, turn off the drive motor, and the limit ring 14 limits the position of the adjusting plate to ensure the stability of the channel width.

[0031] 2. Place the extra-thick plate at the feed end of conveyor belt 1, start the conveyor belt, and the plate moves with the conveyor belt in the cutting direction and enters the first conveying channel. As the channel width formed by the guide wheels 5 on both sides gradually decreases, the edges of the plate will contact the guide wheels during the movement. The guide wheels reduce frictional resistance by rotating, and under the constraint of the gradually changing channel, the offset of the plate is gradually corrected, achieving automatic centering.

[0032] 3. The plate material, after being aligned in the first conveying channel, enters the second conveying channel. At this time, the width direction of the plate material contacts the guide wheels 5 on both sides. The guide wheels 5 slide with the plate material, thereby reducing the transport resistance of the plate material. The plate material is flexibly adjusted by the spring 9 to keep the plate material in the middle position of the conveyor belt 1, providing a reliable guarantee for subsequent cutting operations.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
