[0026] In this embodiment, Figure 3 The orientation shown is described. The conveyor belt 30 is sequentially wound counterclockwise around the telescopic frame 21, the fixed frame 11, the tensioning roller 12 and the driving roller 13 to form an outer "U" shape. The upper surface of the outer "U"-shaped conveyor belt 30 is the conveying surface, and then sequentially wound clockwise around the driving roller 13, the moving roller 22 and the telescopic frame 21 to form an inner "U" shape. When the telescopic frame 21 moves horizontally in a direction away from the fixed frame 11, the moving roller 22 moves horizontally synchronously with the telescopic frame 21. The length of the portion of the conveyor belt 30 forming the inner "U" shape is shortened, and the length of the portion forming the outer "U" shape is increased, the length of the conveying surface is increased, and the conveying path of the material is increased; when the telescopic frame 21 moves horizontally in a direction toward the fixed frame 11, the moving roller 22 moves horizontally synchronously with the telescopic frame 21. The length of the portion of the conveyor belt 30 forming the inner "U" shape is increased, and the length of the portion forming the outer "U" shape is shortened, the length of the conveying surface is shortened, and the conveying path of the material is shortened. By moving the telescopic frame 21, the length of the material conveying path is changed without replacing the conveying device or adding and splicing other conveying devices. The operation is convenient and the material conveying efficiency is improved.

[0027] Specifically, the outer surface of the drive roller 13 is roughened to generate high friction with the conveyor belt 30, thereby driving the conveyor belt 30. The conveying device also includes a stabilizing roller 15 disposed below the telescopic frame 21. The stabilizing roller 15 contacts the telescopic frame 21 to reduce the cantilever of the telescopic frame 21 relative to the connecting frame 26, thereby enhancing the stability of the telescopic frame 21.

[0028] The conveyor belt 30 may be a belt, or a conveying member such as a scraper.

[0029] Please see Figures 1 to 6 In some embodiments, the telescopic assembly 20 further includes a reinforcing component 23 disposed on one side of the telescopic frame 21 , and the reinforcing component 23 contacts the fixing frame 11 .

[0030] Through the above arrangement, the reinforcement component 23 reduces the cantilever of the telescopic frame 21 relative to the connecting frame 26 , thereby enhancing the stability of the movement of the telescopic frame 21 .

[0031] Please see Figures 1 to 6 In some embodiments, the reinforcing component 23 is configured as a roller structure, and an angle is formed between the axial direction of the reinforcing component 23 and the conveying direction of the conveyor belt 30 .

[0032] Through the above arrangement, the reinforcement component 23 is arranged on one side of the telescopic frame 21 and can rotate relative to the telescopic frame 21 to reduce the friction between the conveyor belt 30 and one side of the telescopic frame 21, making the conveyor belt 30 move more smoothly.

[0033] Specifically, the axial direction of the reinforcement component 23 is perpendicular to the conveying direction of the conveyor belt 30. A U-shaped first groove is formed on one side of the telescopic frame 21, and the reinforcement component 23 is arranged at the opening of the first groove, that is, the first groove provides an installation space for the reinforcement component 23.

[0034] Please see Figures 1 to 6 In some embodiments, the telescopic assembly 20 further includes a guide component 24 disposed on the other side of the telescopic frame 21 , and the guide component 24 is located below the conveyor belt 30 .

[0035] In this embodiment, the guide component 24 is used to limit the moving direction of the conveyor belt 30 .

[0036] Please see Figures 1 to 6 In some embodiments, the guide component 24 includes a guide roller 241 and a guide plate 242 . The axial direction of the guide roller 241 has an angle with the conveying direction of the conveyor belt 30 , and the guide plate 242 is inclined downward along the conveying direction of the conveyor belt 30 .

[0037] In this embodiment, a guide roller 241 is rotatably connected to the other side of the telescopic frame 21 to reduce friction between the conveyor belt 30 and the other side of the telescopic frame 21, thereby ensuring smoother movement of the conveyor belt 30. A guide plate 242 is arranged obliquely downward along the conveying direction of the conveyor belt 30. The conveyor belt 30 is wound around the guide roller 241 and does not engage the guide plate 242. The guide plate 242 is used to guide the material being conveyed by the conveyor belt 30 and to limit the location where the material falls.

[0038] Specifically, the axial direction of the guide roller 241 is perpendicular to the conveying direction of the conveyor belt 30. A second U-shaped groove is formed on the other side of the telescopic frame 21, and the guide roller 241 is positioned at the opening of the second groove, providing mounting space for the guide roller 241. Furthermore, the guide rollers 241, coupled with the reinforcement components 23, are positioned on opposite sides of the telescopic frame 21, balancing the telescopic frame 21.

[0039] Please see Figures 1 to 6In some embodiments, the telescopic assembly 20 further includes a connecting frame 26 , which is connected to the bottom of the telescopic frame 21 to raise the telescopic frame 21 .

[0040] In this embodiment, the space below the telescopic frame 21 is used to set the moving roller 22, the driving roller 13, and the inner "U"-shaped part and the outer "U"-shaped lower half of the conveyor belt 30. The connecting frame 26 is also used to install the moving roller 22, and to ensure that the height difference between the upper surface of the telescopic frame 21 and the upper surface of the fixed frame 11 is within a predetermined range, thereby avoiding the conveyor belt 30 located on the upper surface of the telescopic frame 21 and the upper surface of the fixed frame 11 from tilting significantly due to the height difference, thereby avoiding affecting the conveying function of the conveyor belt 30.

[0041] Specifically, the connecting frame 26 is formed by splicing three plates to form a "U"-shaped structure with the opening facing upward. The movable roller 22 is fixed inside the connecting frame 26, and the two ends of the movable roller 22 are rotatably connected to two plates arranged opposite to the connecting frame 26.

[0042] Please see Figures 1 to 6 In some embodiments, the conveying device further includes a receiving component 40 disposed below the telescopic frame 21 , and the telescopic assembly 20 further includes an isolation component 27 , which is used to isolate the conveyor belt 30 from the receiving component 40 .

[0043] In this embodiment, the receiving component 40 is used to receive dust impurities that fall from the conveyor belt 30, preventing the dust impurities from falling into the second drive component 60 and the guide component 70 described below, thereby preventing the dust impurities from entering between the screw rod 62 and the nut block 63 of the second drive component 60 and between the guide rail 71 and the slider 72 of the guide component 70.

[0044] Materials falling onto the floor of the work area pollute the environment, and the receiving component 40 can collect the fallen materials, preventing material waste. To prevent friction between the conveyor belt 30 and the receiving component 40 during movement, the isolation component 27 is provided. This also prevents the conveyor belt 30 from adhering to the materials on the receiving component 40, thereby preventing the conveyor belt 30 from carrying materials onto the floor of the work area.

[0045] Please see Figures 1 to 6 In some embodiments, the receiving component 40 is configured as a trough-shaped structure, with its opening facing the conveyor belt 30 .

[0046] Through the above arrangement, the opening of the receiving component 40 is large enough to receive all the materials dropped from the conveyor belt 30 .

[0047] Please see Figures 1 to 6In some embodiments, the isolation component 27 includes a plurality of isolation rollers 271 , and the plurality of isolation rollers 271 are sequentially spaced apart along the conveying direction of the conveyor belt 30 .

[0048] In this embodiment, the isolation roller 271 is rotatably arranged relative to the conveyor belt 30, so that when the conveyor belt 30 contacts the isolation roller 271, it can drive the isolation roller 271 to rotate, reducing the friction between the two and preventing the conveyor belt 30 from being damaged due to long-term friction.

[0049] Specifically, the isolation roller 271 is disposed within the connecting frame 26, and its ends are rotatably connected to two plates disposed oppositely on the connecting frame 26. The axial direction of the isolation roller 271 is perpendicular to the conveying direction of the conveyor belt 30, and two isolation rollers 271 are spaced apart along the conveying direction of the conveyor belt 30.

[0050] Please see Figures 1 to 6 In some embodiments, the fixing assembly 10 includes a plurality of tensioning rollers 12, which are arranged in sequence and spaced apart in a first direction. There is an angle between the first direction and the conveying direction of the conveyor belt 30. In the vertical direction, the top surface of the tensioning roller 12 located at the top is higher than the moving roller 22, and the bottom surface of the tensioning roller 12 located at the bottom is lower than the moving roller 22.

[0051] In this embodiment, the setting of the tensioning roller 12 can make the inner "U"-shaped part of the conveyor belt 30 located inside the outer "U"-shaped part, thereby enabling the operation of extending the conveying surface of the conveyor belt 30 to be smoothly implemented. In addition, the tensioning roller 12 can tighten the conveyor belt 30, making the conveying more stable and smooth.

[0052] Specifically, the first direction is perpendicular to the conveying direction of the conveyor belt 30 .

[0053] Please see Figures 1 to 6 In some embodiments, the fixed frame 11 is formed as a frame-shaped structure and has a mounting surface. The conveying surface of the conveyor belt 30 is arranged above the mounting surface. The telescopic frame 21 is at least partially located inside the fixed frame 11 and below the mounting surface. The telescopic frame 21 can be driven to extend or retract the fixed frame 11.

[0054] In this embodiment, the upper surface of the fixed frame 11 serves as the mounting surface, and the conveying surface of the conveyor belt 30 is located above the mounting surface and the upper surface of the telescopic frame 21. The drive roller 13, stabilizing roller 15, movable roller 22, reinforcement member 23, connecting frame 26, and isolation member 27 are all located within the frame-shaped fixed frame 11. This isolates all six components from the outside world, protecting them and extending their service life. Furthermore, these components can be concealed, enhancing the overall aesthetics of the conveyor device.

[0055] Please see Figures 1 to 6 In some embodiments, the fixing assembly 10 further includes an extension frame 14, the extension direction of the extension frame 14 is the same as the conveying direction of the conveyor belt 30, the extension frame 14 is arranged on one side of the fixing frame 11, and protrudes horizontally from the fixing frame 11, and the telescopic frame 21 slides with the extension frame 14.

[0056] In this embodiment, the extension frame 14 is fixedly connected to the fixed frame 11 and extends toward the conveying direction of the conveyor belt 30 to support the portion of the telescopic frame 21 located outside the fixed frame 11 to improve the telescopic stability of the telescopic frame 21 .

[0057] Specifically, a pulley is provided on the extension frame 14 , and the telescopic frame 21 is slidably engaged with the extension frame 14 via the pulley.

[0058] Please see Figures 1 to 6 In some embodiments, the conveying device further includes a platform 80 and a bracket 90 fixed below the platform 80 , and the fixing frame 11 and the receiving component 40 are both fixed on the platform 80 .

[0059] The conveying device also includes a first drive assembly 50, which includes a first motor 51 fixed to a bracket 90, a direction changer 52 connected to the output end of the first motor 51, and two transmission wheels 53. One transmission wheel 53 is connected to the output end of the direction changer 52. The drive roller 13 is rotatably connected to the side wall of the fixed frame 11, and one end of the drive roller 13 extends outside the fixed frame 11. The other transmission wheel 53 is connected to the same end of the drive roller 13. The drive roller 13 is connected to the direction changer 52 via the transmission wheel 53 and a transmission belt wrapped around the transmission wheel 53. When the first motor 51 is started, it drives the drive roller 13 to rotate, thereby driving the conveyor belt 30 to move. The direction changer 52 is used to change the output direction of the first motor 51, thereby changing the installation position of the first motor 51, making the structure of the entire conveying device more compact.

[0060] The conveying device also includes a second drive assembly 60, which includes a second motor 61, a screw 62 connected to the output end of the second motor 61, and a nut block 63 threadedly mounted on the screw 62. The end of the screw 62 facing away from the second motor 61 is rotatably connected to the inner wall of the fixed frame 11, thereby stabilizing the rotation of the screw 62 and enabling the nut block 63 to move stably along the screw 62. A plate at the bottom of the connecting frame 26 is fixedly connected to the nut block 63, so that it can move horizontally under the drive of the nut block 63. The second motor 61 is located outside the fixed frame 11 and fixed to the bracket 90.

[0061] The conveying device also includes a guide assembly 70, which includes a guide rail 71 fixed to the platform 80 and a slider 72 slidably connected to the guide rail 71. The guide rail 71 is parallel to the screw rod 62. The slider 72 is fixedly connected to the plate at the bottom of the connecting frame 26. When the connecting frame 26 moves horizontally driven by the nut block 63, the slider 72 moves along the guide rail 71 to improve the stability of the movement of the telescopic frame 21. The slider 72 is a roller slider that can reduce the friction between the slider 72 and the guide rail 71, making the slider 72 move more smoothly.

[0063] Starting the second motor 61 to rotate forward causes: the second motor 61 drives the screw rod 62 to rotate forward, the nut block 63 moves along the screw rod 62 in the direction away from the second motor 61, and drives the connecting frame 26 to move in the same direction. At the same time, the slider 72 slides in the same direction along the guide rail 71, the telescopic frame 21 extends horizontally out of the fixed frame 11, driving the movable roller 22 to move horizontally, the length of the inner "U"-shaped part of the conveyor belt 30 is shortened, and the length of the outer "U"-shaped part is increased, thereby extending the conveying surface.

[0064] When the conveying surface of the conveying device of this application needs to be shortened:

[0065] Starting the second motor 61 to reverse, the second motor 61 drives the screw rod 62 to reverse, the nut block 63 moves along the screw rod 62 toward the second motor 61, and drives the connecting frame 26 to move in the same direction. At the same time, the slider 72 slides in the same direction along the guide rail 71, the telescopic frame 21 retracts horizontally to the fixed frame 11, driving the movable roller 22 to move horizontally, the length of the inner "U"-shaped part of the conveyor belt 30 increases, and the length of the outer "U"-shaped part shortens, thereby shortening the conveying surface.

[0066] A second aspect of the present invention provides a conveying system, comprising a material transporting device and the above-mentioned conveying device, wherein the material transporting device is arranged upstream and / or downstream of the conveying device.
