Description

Double rollers for preventing rolling of belt conveyor

The present invention relates to a meandering prevention double roller of the belt conveyor, and more particularly to a meandering prevention double roller of the belt conveyor to suppress the meandering of the belt conveyor by using the upper pressing ring roller and the lower ring roller.

Conventionally, as shown in FIG. 1, ring rollers 23 are provided to contact the lower surface of the belt 20, and stopper rings 22 are provided on both side surfaces of the ring roller, respectively. Meandering is suppressed.

However, when the meandering of the belt 20 becomes severe, the side surface of the belt is overlapped while contacting the inner surface of the stopper ring 22, resulting in a phenomenon in which the side is separated in multiple layers by the vertical movement of the belt.

In addition, when the meandering of the belt 20 is further worsened, the side of the belt is placed on the upper portion of the stopper ring 22 to proceed. At this time, the belt is broken while a deep groove is generated under the side of the belt by the tension of the belt. The width of the belt becomes much narrower.

Therefore, the production cost is increased due to the shortening of the life of the belt 20, and as a considerable amount of the package drops, the processing cost is unnecessarily generated. Problems arise.

The object of the present invention is to provide a belt roller double roller for preventing meandering and reducing the production cost according to the maintenance of the equipment. have.

In order to achieve the above object, the present invention is a rubber drum is in contact with the lower surface of the return belt and the side ring is externally fastened by a fixed drum and a plurality of bolts, respectively, on both ends of the shaft drum, both ends of the fixed shaft by the fixing plate, respectively A lower ring roller inserted into the fixing groove of the bracket to be fixed; While the rubber drum is in close contact with the upper surface of the return belt, both ends of the axial drum are respectively coupled to the mounting groove of the side ring, and both ends of the fixed shaft is composed of an upper pressing roller which is inserted into the fixing groove of the bracket, respectively. Provides double rollers to prevent meandering of belt conveyors.

The configuration of the present invention will be described with reference to the drawings.

Figure 2 is an exploded perspective view showing a meandering prevention double roller of the belt conveyor according to the present invention, Figure 3 is a perspective view showing a meandering prevention double roller of the belt conveyor according to the present invention.

First, the upper pressing roller 7 and the lower ring roller 2 have four rubber drums 14 and 11 which are in contact with the lower surface of the return belt 20, respectively, being mounted on the shaft drums 15 and 12. On the inner circumferential surface of 12), high savings (16, 13) are formed so that both ends are extended.

At this time, a pair of side rings (3) in which the fixed drum (4) of the cylindrical tube is fixed to the inner circumferential surface is formed on each side of the outer circumferential surface is formed with an arc-shaped mounting groove (5), the lower ring roller (2) Both ends of the axial drum are respectively fastened by three bolts 6 which are screwed vertically to the outer circumferential surface of the fixed drum.

And the pair of brackets (1) formed in a substantially Z shape is fixed grooves (10, 19) formed in a substantially c-shape is formed in a diagonal direction, the fixing plate 31 is welded horizontally to the outer surface, respectively, The fixed plate 31 is fixed to the belt conveyor equipment by bolts.

Here, the fixing shaft of the lower ring roller (2) in which the axial drum (12) is fastened to the fixing drum (4) of the side ring (3) in the upper fixing groove (19) of the bracket (1). 13) are inserted to be rotatable, respectively, wherein the mounting groove 5 of the side ring is in the 11 o'clock position.

In addition, the upper pressing roller 7 has both ends of the shaft drum 15 coupled to the mounting groove 5 of the side ring 3, respectively, and the fixing shaft 16 has a lower recess of the bracket 3. It is inserted in 10 so that rotation is possible, respectively.

Hereinafter will be described the operation of the present invention.

In the rotating belt conveyor system, the return belt 20 moves between the rubber drum 14 of the upper pressing roller 7 and the rubber drum 12 of the lower ring roller 2. When moving toward the side ring (3) fixed to both sides the side ring serves as a stopper to prevent the belt from being pushed.

At this time, the upper pressing roller 7 which is formed in the same shape as the lower ring roller 2 and installed in the 11 o'clock direction of the lower ring roller strongly presses the upper surface of the return belt, while the fixing shafts 16 at both ends thereof are brackets (1). Because the return belt 20 is pushed in the direction of the side ring (3) because it is coupled to the fixing groove 10 of the) to block the phenomenon that overlaps or escapes from the side ring.

Eventually, the side ring 3 acting as a stopper on both sides of the lower ring roller 2 and the upper and lower rollers are moved in the vertical direction of the belt by the complementary compound action of the return belt 20. It blocks the phenomenon and prevents the belt from meandering.

The present invention can prevent damage and breakage of the belt, reduce material costs and production costs, prevent production loss due to belt breakage, and according to the convection function of various types of meander prevention rollers to prevent belt meandering. It provides the effect of increasing material management and use efficiency by unifying material items.
