Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a belt backstop comprises a beam 1, an electric roller 2, a carrier roller 3, a support 4, a cylinder 5, a fixing frame 6, a belt backstop 7, a pressing plate 8, a support 9, a pulley 10, a rubber cushion block 11, a fixing block 12, a contact sensor 13 and a conveying belt 14, wherein the beam 1 is connected with the electric roller 2 in an inserting and rotating mode through a rotating shaft, 2 electric rollers 2 are arranged in an inclined mode, the conveying belt 14 is sleeved on the outer wall of the electric roller 2, the fixing frame 6 is fixed at the lower end of the beam 1 and is arranged in an Contraband type structure, the cylinder 5 is fixed on the fixing frame 6 through a motor fixing frame, the fixing position of the cylinder 5 is not prone to shift due to the structural arrangement of the fixing frame 6, good preparation conditions are provided for segmented extrusion work of the conveying belt 14, the pressing plate 8 is fixed on a telescopic shaft of the cylinder 5, the rubber cushion block 11 is arranged in the position parallel to the pressing plate 8, and the rubber cushion block 11 is connected to the fixing block 12 in a gluing mode, the fixing block 12 is fixed at the bottom end of the cross beam 1, the pressure plate 8 is influenced by the acting force of the air cylinder 5, the conveying belt 14 is fixed between the pressure plate and the rubber cushion block 11 in a segmented extrusion manner, the protection effect on the conveying belt 14 is further increased, the non-return effect is better, the supports 9 are fixed on two sides of the pressure plate 8, the supports 9 are connected with the pulleys 10 in an inserting and rotating manner through the rotating shafts, the pulleys 10 are in contact with the fixing frame 6, the sliding limiting effect is added on the moving track of the pressure plate 8 by the pulleys 10, the moving process of the pressure plate 8 is smooth and stable, the supports 4 are uniformly fixed at the top end of the cross beam 1, the supports 4 are connected with the carrier rollers 3 in an inserting and rotating manner through the rotating shafts, the carrier rollers 3 are in contact with the top end of the inner wall of the conveying belt 14, one end of the belt non-return device 7 is fixed on the cross beam 1 through bolts, and the other end of the belt non-return device 7 is inserted into a chord tangent angle between one electric roller 2 and the inner wall of the conveying belt 14, belt backstop 7 one end sets up to "ten" style of calligraphy structure, and the segmentation parallel department of belt backstop 7 is equipped with contact sensor 13, contact sensor 13's model sets up to MR-T6N-40-LED, contact sensor 13 fixes on crossbeam 1, and contact sensor 13 passes through wire and cylinder 5 electric connection, contact sensor 13 is along with belt backstop 7's tensile operation and intelligent trigger cylinder 5 carries out work, let the contrary effect of checking of transport belt 14 go on automatically, the consumption of manpower has been avoided.
