DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the present utility model in detail with reference to the embodiments:

[0025] As Figures 1-5 shown, the present utility model provides a belt conveyor belt pressing device, including a mounting frame 1.

Belt pressing mechanisms 4 are installed in the middle of both sides of the mounting frame 1. Limiting components 5 are symmetrically installed on both sides of the belt pressing mechanism 4. The limiting component 5 includes a side frame 51. The bottom end of the side frame 51 is connected to both sides of the lower end of the belt pressing mechanism 4. An edge frame 52 is fixedly connected to the front end of the side frame 51. An elastic sheet 53 is movably connected to the inner side of the edge frame 52. A groove 54 is opened at the rear end of the inner side of the edge frame 52. Multiple groups of springs 55 are equidistantly distributed inside the groove 54.

[0026] The bottom end of the side frame 51 is fixedly connected to both sides of the lower end of the connection frame 41, and the inside of the edge frame 52 is movably connected to the lower end face of the conveyor belt 3.

[0027] The driving roller 2 can drive the conveyor belt 3 to convey under the drive of a peripheral motor.

[0028] As Figures 3-4 shown, the belt pressing mechanism 4 includes a connection frame 41. The lower end of the connection frame 41 is movably installed in the middle of both sides of the upper end of the mounting frame 1. A through hole 42 is opened at the upper end of the connection frame 41. A bolt 43 is movably inserted into the through hole 42. An activity plate 44 is movably installed inside the connection frame 41. A plurality of groups of screw holes 45 are equidistantly opened on the surface of the activity plate 44. The top of the activity plate 44 is fixedly connected to a top plate 46. A sleeve one 47 is fixedly connected to the inner side of both groups of top plates 46. An activity rod 48 is movably connected inside both groups of sleeves one 47. A hanging frame 49 is fixedly sleeved in the middle of the activity rod 48. The lower end of the hanging frame 49 is fixedly connected to a mounting frame 410. A double-shaft motor 411 is fixedly connected inside the mounting frame 410. A lead screw 412 is rotatably installed on both sides of the double-shaft motor 411. A sleeve two 413 is movably sleeved on the outside of the lead screw 412. A pulley 418 is fixedly sleeved on the outside of the sleeve two 413. A belt pressing wheel 414 is rotatably sleeved on the outside of the pulley 418. Limit plates one 415 are symmetrically and fixedly installed at the left and right ends of the activity rod 48. A limit plate two 416 is fixedly connected to the top of the lead screw 412. A screw sleeve 417 is fixedly connected to the middle of the left end of the sleeve two 413.

[0029] The bolt 43 is in threaded connection with the screw hole 45, and the outside of the limit plate one 415 is in limit sliding connection with the inside of the sleeve one 47.

[0030] The outside of the lead screw 412 is in threaded connection with the inside of the screw sleeve 417. The right end of the sleeve two 413 is fixedly connected to the inner side of the top of the activity plate 44. The outside of the limit plate two 416 is in limit sliding connection with the inside of the sleeve two 413.

[0031] Installation holes are reserved on both sides of the bottom of the connection frame 41. The connection frame 41 is movably installed in the middle of both sides of the upper end of the mounting frame 1 through the installation holes and a peripheral screw.

[0032] By providing the limit plates one 415 and limit plates two 416, the sleeves one 47 and sleeves two 413 can be limited to prevent the sleeves one 47 and sleeves two 413 from separating from the lead screw 412 or the activity rod 48 during movement. By loosening and pulling out the bolt 43 from the screw hole 45, the activity plate 44 can be moved up and down, and then the belt pressing wheel 414 can be driven to move synchronously, so that the height of the belt pressing wheel 414 can be adjusted. By adjusting the distance between the two belt pressing wheels 414, the device can be made suitable for conveyor belts 3 of different widths.

[0033] AsFigure 5 As shown, the edge frame 52 is in a "C" shape.

[0034] One end of the spring 55 is fixedly connected to the inner side of the groove 54, and the other end is fixedly connected to the rear end of the elastic sheet 53.

[0035] By providing the elastic sheet 53 and the spring 55, an offset buffering effect can be exerted on the conveyor belt 3, avoiding side friction and tearing caused by the position offset of the conveyor belt, thereby improving the service life of the conveyor belt 3.

[0036] Next, the working principle of the belt conveyor belt pressing device will be specifically described.

[0037] As Figures 1-5 shown, when the belt conveyor belt pressing device is in use, when the conveyor belt is driven, the conveyor belt can drive the pressing wheel 414 to rotate together, so that the pressing wheel 414 can rotate on the sleeve wheel 418, and the rotating pressing wheel 414 can be used to guide both sides of the conveyor belt, thereby preventing the conveyor belt 3 from fluttering on the surface of the driving roller 2, thus playing an upper limit position role in the transportation of the conveyor belt 3, thereby adjusting the upper end of the conveyor belt 3. When it is necessary to adjust the distance between the two pressing wheels 414, the double-shaft motor 411 can be started. The double-shaft motor 411 can drive the screw rods 412 on both sides to rotate, so that the two screw rods 412 can push the two sleeve two 413 to move towards or away from each other through the screw sleeves 417 connected by threads. At the same time, the sleeve two 413 can drive the movable plate 44 to move synchronously. When the movable plate 44 moves, it will drive the sleeve one 47 to slide synchronously on the movable rod 48, thereby improving the stability of the movement of the two movable plates 44 and the pressing wheels 414, and then realizing the adjustment of the distance between the two pressing wheels 414; by the inner side of the edge frame 52 being in contact with both sides of the lower end of the conveyor belt 3, and at the same time the elastic sheet 53 being in contact with the end faces of both sides of the lower end of the conveyor belt 3, and using the elastic sheet 53 and the spring 55 can buffer the offset direction when the conveyor belt 3 is offset, avoiding side friction and tearing caused by the position offset of the conveyor belt 3, thereby improving the service life of the conveyor belt 3 and improving the practicability of the device.

[0038] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
