Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, and particularly relates to a conveyor belt protection pressing strip. Background Art

[0002] A conveyor belt is a rubber, fiber, and metal composite product or a plastic and fabric composite product used to carry and transport materials in a belt conveyor.

[0003] The common structure of a conveyor belt includes rotating shafts arranged on both sides of the conveyor belt. The rotation of the rotating shafts drives the conveyor belt wound around the upper side thereof to move, thereby realizing the transportation of items. In the above process, the movement trajectory of the conveyor belt needs to be determined to ensure the stability of transportation. The common method for limiting the conveying direction of the conveyor belt is to use a limiting strip arranged on the rotating shaft to limit the conveyor belt, thereby adjusting the tension of the conveyor belt. However, since the hard contact method is used, it is easy to damage the outer wall of the conveyor belt. In view of this, we propose a conveyor belt protection pressing strip.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] The present utility model will be further described below with reference to the embodiments.

[0030] Embodiment: A conveyor belt protection strip, comprising a side plate 300 which is symmetrically arranged on both sides of the rotating shaft 100, and the height of the side plate 300 in the vertical direction is greater than the diameter of the rotating shaft 100; and a pressing plate 400 movably connected to the side plate 300, with an avoiding groove 401 formed in the middle of the pressing plate 400, and the conveyor belt 200 wound around the middle of the two rotating shafts 100 passes through the avoiding groove 401; and adjusting rods 440 arranged on the two pressing plates 400, and the adjusting rods 440 can adjust the distance between the two pressing plates 400. By providing the side plate 300, it can effectively limit the conveying trajectory of the conveyor belt 200 along the axial direction of the rotating shaft 100, and a flexible layer is provided on the outer wall of the side plate 300, which can reduce the problem of edge damage of the conveyor belt 200 caused by relative displacement while limiting the conveyor belt 200.

[0031] Further, in the present application, the outer wall of the side plate 300 is slidably engaged with the outer wall of the rotating shaft 100, and a clamping groove 301 is provided at the middle position of the side plate 300. The clamping groove 301 is slidably engaged with the driving shaft fixedly installed on the side wall of the rotating shaft 100. A clamping groove 301 is provided in the middle of the side plate 300, and lubricating oil is coated on the inner wall of the clamping groove 301. When the driving shaft slides relative to the clamping groove 301, it can reduce the wear of the clamping groove 301 on the driving shaft and ensure the normal and efficient rotation of the rotating shaft 100.

[0032] It further includes a mounting block 310 fixedly installed on the side plate 300, and a limiting groove 311 is provided in the middle of the mounting block 310; a limiting block 420 is fixedly installed on the outer wall of the pressing plate 400, and the limiting block 420 is slidably connected inside the limiting groove 311. The adjusting rod 440 is a threaded rod, and a threaded groove 402 is provided on the pressing plate 400. The adjusting rod 440 is meshed with the threaded groove 402; when the adjusting rod 440 rotates clockwise, the two pressing plates 400 approach each other. Specifically, in the present application, due to the relationship that the limiting block 420 is slidably connected inside the limiting groove 311, the adjustment trajectories of the two pressing plates 400 can be effectively limited. Specifically, when the two pressing plates 400 approach each other, they will squeeze the conveyor belt 200, thereby making the conveyor belt 200 have different degrees of expansion, so as to adapt to different conveying requirements. It should be noted that in the present application, multiple adjusting rods 440 are provided, and they can be adjusted synchronously. As an implementation manner, one of the adjusting rods 440 can be set as a threaded rod, and the rest can be set as guide rods to play a guiding role.

[0033] A bladder 330 is provided between the middle parts of the two limiting blocks 420, and the bladder 330 is in communication with a communication hole 312 provided in the limiting groove 311; and an elastic bladder 430 is provided on the side wall of the avoidance groove 401, and the communication hole 312 is in communication with the elastic bladder 430 through a connecting pipe 320. Specifically, through the bladder 330 provided between the middle parts of the two limiting blocks 420, when the relative position between the two limiting blocks 420 changes, the correspondingly provided bladder 330 will be compressed, and then the gas in the bladder 330 will enter the inside of the elastic bladder 430 through the connecting pipe 320. And when the pressing plate 400 adjusts its position, it will correspondingly squeeze the conveyor belt 200. During this process, the expanded elastic bladder 430 will expand, so that the conveyor belt 200 is in elastic contact with the elastic bladder 430, thereby reducing the damage to the conveying surface of the conveyor belt 200 and improving its service life.

[0034] An arc-shaped plate 410 is further provided on the outer wall of the pressing plate 400, and a rubber layer is provided on the outer wall of the arc-shaped plate 410. The distance of the avoidance groove 401 in the vertical direction is greater than the thickness of the conveyor belt 200. Specifically, when the pressing plates 400 approach each other and are affected by the arc surface of the rotating shaft 100, the conveyor belt 200 located between the pressing plate 400 and the rotating shaft 100 is in a bent state, and the provided arc-shaped plate 410 can well fit on the outer wall of the conveyor belt 200 to ensure the stable transmission of the conveyor belt 200.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
