Description

Belt conveyor roller

Technical Field

The utility model relates to a belt conveyor field especially relates to a belt conveyor cylinder.

Background

The belt conveyor is widely applied to various industries such as household appliances, electronics, electric appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food and the like, and the assembly, detection, debugging, packaging, transportation and the like of objects. As a main component on a belt conveyor, the conveyor rollers are arranged mainly at the head, tail or turning section of the belt conveyor, which takes over the drive action of the belt. However, most conveyor rollers are sealed straight rollers, so that the falling bulk materials are easily adhered to the rollers when the bulk materials are transported, the belt is off tracking, once the rollers are worn, the maintenance force is increased, and even the conveying accessories need to be replaced. The straight-tube type conveying roller has a thermal expansion effect after a belt works for a long time, so that the belt is loosened, and the straight-tube type conveying roller is an important reason for deviation of the belt.

Therefore, in order to analyze various reasons of deviation and loosening and falling of the conveyor belt, a non-closed belt conveyor roller with a tensioning function needs to be designed.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application adopts the non-closed design through providing a belt conveyor roller to the cavity is inside to support, can not become drum-shaped and belt contact through the curved plate branch, thereby give the belt in order to provide tensile force, with the conveyer roller sizing that provides among the solution above-mentioned background art, off tracking, phenomenons such as drop.

The embodiment of the application provides a belt conveyor roller, which comprises a cavity body, two terminal internal weld of cavity have the support pipe, two terminal inside nestings of support pipe have the axle sleeve, it is fixed with the pivot through both ends axle sleeve to support the pipe, the axis that cavity both ends outside surface used the cavity encircles a week and has a plurality of longitudinal tie piece, the axis that cavity mid portion both sides surface used the cavity encircles a week and has a plurality of cross connection piece, longitudinal tie piece and cross connection piece are respectively through stationary blade and curved plate fixed connection.

Preferably, the cavity is formed by butt welding a group of hollow cones with the inclination of 30-60 degrees, and the middle of the cavity is convex.

Preferably, bearings are fixed at two tail ends of the rotating shaft, and the supporting seat is connected with the outside of the bearings.

Preferably, each curved plate is symmetrically and fixedly connected with a pair of the longitudinal connecting pieces at two sides, and is symmetrically and fixedly connected with a pair of the transverse connecting pieces at the middle part.

Preferably, the curved plate is uniformly distributed at intervals of 2 cm-4 cm around the axis of the cavity to form a drum-shaped body, and the outer surface of the curved plate is smooth.

The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:

1. this application forms the drum-shaped body through setting up the cavity and connecting the curved plate, and the curved plate has certain flexibility, still can provide the tensile force to the belt after the heat rises to avoid the belt to produce the condition that relaxes and drop after long-time work, improve the stability of carrying work.

2. This application passes through longitudinal connection piece and transverse connection piece connection cavity and curved plate, sets up through the connection of vertical and horizontal two directions, eliminates the effect fatigue strength of single direction stress, improves the support intensity to curved plate to improve the stability of carrying work, improve life.

3. This application is distributed through the curved plate and is set up, forms certain space on the cylinder surface, can make the bulk cargo of transportation drop from the clearance smoothly, avoids the bulk cargo to bond, makes the belt off tracking, improves the stability of carrying work.

Detailed Description

As shown in fig. 1-5, a belt conveyor cylinder, including cavity 1, cavity 1 is formed by two big disc butt welding of a set of inclination for 30 ~ 60 hollow cone, and the centre is protruding form, and hollow cone is the shaping steel construction, and two terminal inside welds of cavity 1 have support pipe 2, and two terminal inside nestings of support pipe 2 have axle sleeve 3, and support pipe 2 is fixed with pivot 4 through both ends axle sleeve 3, and two ends of pivot 4 are fixed with bearing 6, through bearing 6 outer joint support seat to drive support pipe 2 and cavity 1 and rotate under the rotation of pivot 4. The both ends outside surface of cavity 1 encircles a week with the axis of cavity 1 and has a plurality of longitudinal tie 7, and the even welding of a week has a plurality of transverse tie 8 in cavity 1 middle part both sides surface encircles a week with the axis of cavity 1, and longitudinal tie 7 and transverse tie 8 are respectively through stationary blade 9 and curved plate 10 fixed connection, and every curved plate 10 bilateral symmetry fixed connection is a pair of longitudinal tie 7, and at a pair of transverse tie 8 of middle part symmetry fixed connection, through the connection setting of vertical and horizontal two directions, eliminate the effect fatigue strength of single direction stress, improve the support intensity to curved plate 10 to improve the stability of carrying work, improve life.

The curved plate 10 is uniformly distributed at intervals of 2 cm-4 cm around the axis of the cavity 1 to form a drum-shaped body, a certain gap is formed on the surface of the roller, so that transported bulk materials can smoothly fall from the gap, the adhesion of the bulk materials is avoided, a belt is off tracking, and the stability of conveying work is improved. The curved plate 10 has smooth outer surface and certain flexibility, and can provide tension for the belt after thermal expansion, thereby avoiding the situation that the belt loosens and falls off after long-time work and improving the stability of conveying work. As shown in fig. 6, in the transmission state after the two groups of belt conveyor rollers are connected with the belt 11, the belt can be in a tensioning state through the drum-shaped rollers, the transmission work is stable, and the whole service life is prolonged.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements and the like can be made in the technical solutions of the foregoing embodiments or in some technical features of the foregoing embodiments.
