[0022] The technical solution of this utility model will be described in detail below with reference to specific embodiments and the accompanying drawings.

[0023] As attached Figure 1 - Appendix Figure 5 As shown in an illustrative embodiment of the sheet metal conveying device of this utility model, the conveying device is installed in a CNC sheet metal cutting machine and is used to transport the sheet metal to a sawing device for sawing. The conveying device includes a conveying assembly 3 and a positioning assembly 2 arranged in parallel. The conveying assembly includes a frame 1, a mounting plate 33, a roller mechanism 35, a conveyor belt 31, a first drive mechanism 32, and a second drive mechanism 36.

[0024] The frame 1 is welded from profiles and is used to support the mounting plate 33, roller mechanism 35, conveyor belt 31, first drive mechanism 32 and second drive mechanism 36.

[0025] As attached Figure 1 As shown, the mounting plate 33 is fixedly mounted on the frame 1 along the length of the frame 1 by bolts. The side of the mounting plate 33 facing the frame 1 body is the inner side plate, and the side of the mounting plate 33 away from the frame 1 body is the outer side plate.

[0026] The telescopic plate 34 is parallel to and opposite to the mounting plate 33 on the outer side of the mounting plate 33. It is slidably connected to the mounting plate 33 through a sliding connection mechanism, so that the telescopic plate 34 can extend and retract along the length direction of the mounting plate. In this embodiment, the plate is fed in from the first end of the length direction of the mounting plate 33 and the telescopic plate 34, and the plate is fed in from the second end of the length direction of the mounting plate and the telescopic plate 34.

[0027] The roller mechanism 35 is disposed between the mounting plate 33 and the telescopic plate 34, and includes a first fixed roller 351, a first movable roller 352, a second fixed roller 353, and a second movable roller 354.

[0028] The first fixed roller shaft 351 is fixedly installed at the first end of the mounting plate 33 along its length; the first movable roller shaft 352 is fixedly installed at the second end of the telescopic plate 34 along its length; and the second fixed roller shaft 353 is fixedly installed at the second end of the mounting plate 33 along its length. One end of the second movable roller shaft 354 is slidably connected to the mounting plate 33, and the other end is fixedly connected to the telescopic plate 34.

[0029] The conveyor belt 31 is a telescopic belt, which is wound between the first fixed roller shaft 351, the first movable roller shaft 352, the second fixed roller shaft 353 and the second movable roller shaft 354, and is used to transport the sheet metal.

[0030] The first drive mechanism 32 consists of a geared motor and a synchronous pulley, which is fixedly mounted on the frame 1 by bolts. The power output end is connected to the conveyor belt 31 to drive the conveyor belt 31 to rotate.

[0031] The second drive mechanism 36 is an electric push rod or cylinder, which is fixedly installed on the frame 1 along the length of the telescopic plate 34. The power output end is connected to the telescopic plate 34 and is used to drive the telescopic plate 34 to extend and retract.

[0032] In the above illustrative embodiment, by setting a sliding telescopic plate 34 and equipping it with an independent second drive mechanism 36 to drive the telescopic plate 34, the overall length of the conveying device can be flexibly adjusted. At the same time, by setting the second moving roller 354, the conveyor belt 31 can complete the belt length compensation and tension adjustment during the telescopic plate 34's extension and retraction. This allows the conveying device to adapt to the conveying needs of plates of different lengths, significantly improving the versatility of the conveying device and reducing the equipment replacement or modification costs caused by changes in plate size.

[0033] In some embodiments of this utility model, the first fixed roller shaft 351 and the first movable roller shaft 352 are in the same horizontal plane, so that the upper surface of the conveyor belt 31 between them naturally forms a horizontal section, ensuring that the section of the conveyor belt 31 carrying the plate is in a horizontal state, and preventing the plate from sliding, shifting or jamming due to the tilt of the working surface during the conveying process.

[0034] In some embodiments of this invention, the second movable roller 354 is positioned horizontally between the first fixed roller 351 and the first movable roller 352, and vertically between the first movable roller 352 and the second fixed roller 353. This arrangement makes the wrap angle distribution of the conveyor belt 31 more reasonable. No matter how the second movable roller 354 moves with the telescopic plate 34, the conveyor belt 31 can always maintain a good tension, avoiding the problem of slippage, loosening, or detachment of the conveyor belt 31 caused by sudden tension changes during the telescopic process.

[0035] In some embodiments of this utility model, to achieve a sliding connection between the telescopic plate 34 and the mounting plate 33, a first guide groove 331 extending along its length is provided on the mounting plate 33. A guide rail 341 with a cross-section matching the first guide groove 331 is installed at a corresponding position on the telescopic plate 34. The guide rail 341 is slidably disposed in the first guide groove 331. The connection method of sliding cooperation between the guide rail 341 and the first guide groove 331 can effectively constrain the movement trajectory of the telescopic plate 34, ensuring that it can only slide smoothly in a preset direction.

[0036] In some embodiments of this utility model, a second guide groove 332 extending along its length is provided on the mounting plate 33. One end of the second moving roller shaft 354 is slidably installed in the second guide groove 332 through a slider or bearing seat, which ensures that the axis of the second moving roller shaft 354 always maintains the correct direction when it moves with the telescopic plate 34, and will not deflect or tilt.

[0037] In some embodiments of this utility model, the roller mechanism 35 further includes a third fixed roller 355 and a fourth fixed roller 356. The third fixed roller 355 and the fourth fixed roller 356 are both fixedly installed on the frame 1 and are arranged sequentially below the first fixed roller 351, and are staggered with the first fixed roller in the vertical direction. The conveyor belt 31 starts from the first fixed roller 351, passes through the second fixed roller, the second moving roller 354, the third fixed roller, the third fixed roller 355 and the fourth fixed roller 356 in sequence, and then returns to the first fixed roller 351 to form a closed loop.

[0038] By adding a third fixed roller 355 and a fourth fixed roller 356 and optimizing the wrapping path of the conveyor belt 31, the contact wrap angle between the conveyor belt 31 and each roller is larger, and the transmission is more reliable. At the same time, this S-shaped wrapping path can make more efficient use of the length of the conveyor belt 31 and provide better tension self-adaptation capability when the conveyor belt 31 extends and retracts with the telescopic plate 34.

[0039] In some embodiments of this utility model, the positioning component includes a lower positioning plate 21, an upper positioning plate 24, and a flipping claw mechanism 22.

[0040] The lower positioning plate 21 is mounted on the frame 1 and is arranged parallel to the conveyor belt 31 wound between the first fixed roller shaft 351 and the first moving roller shaft 352. Two flipping claw mechanisms 22 are arranged opposite each other at both ends of the lower positioning plate 21 along its length. The upper positioning plate 24 is arranged opposite to the lower positioning plate, and its two lengthwise portions are respectively connected to the two flipping claw mechanisms 22. By setting up a positioning assembly consisting of the lower positioning plate 21, the upper positioning plate 24, and the flipping claw mechanisms 22, after the sheet material is conveyed to its position, it can be reliably confined within the positioning space formed by the lower positioning plate 21, the upper positioning plate 24, and the two flipping claw mechanisms 22, achieving automatic and precise positioning of the sheet material and providing an accurate positional reference for subsequent cutting processes.

[0041] In some embodiments of this utility model, the flipping claw mechanism 22 includes a fixing member and a flipping claw member.

[0042] The fixing component is fixedly installed on the frame 1, and the flipping claw component is rotatably connected to the fixing component via a rotating shaft. The flipping claw component has an initial position and an open position. When the flipping claw component is in the initial position, it is connected to the upper positioning plate 24.

[0043] In this embodiment, the flipping claw mechanism 22 adopts a rotatable design. When it is necessary to put in or take out the plate, the flipping claw can be opened. When it is necessary to position, the flipping claw returns to the initial position and works in conjunction with the upper positioning plate 24 to limit the plate from the side and the top. This design greatly enhances the flexibility and ease of use of the positioning component.

[0044] In some embodiments of this utility model, the positioning component further includes a top-pushing mechanism 25 and a side-pushing mechanism 26.

[0045] The jacking mechanism 25 is vertically mounted on the frame 1. When its power output end extends, it pushes the plate on the lower positioning plate 21 to abut against the upper positioning plate 24.

[0046] The side-pushing mechanism 26 is installed at one end of the lower positioning plate 21; when the power output end of the side-pushing mechanism 26 extends, it pushes the plate on the lower positioning plate 21 to abut against the flipping claw mechanism 22 at one end of the lower positioning plate 21.

[0047] By adding a top-pushing mechanism 25 and a side-pushing mechanism 26, precise positioning of the sheet metal in three-dimensional space is achieved, thereby effectively ensuring the processing quality of subsequent cutting processes. Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.

[0048] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
