The present invention relates to a cone belt conveyor return roller, and more particularly, by using a resin material with a resin material cone roller drum (Fig. 11) manufactured by injection molding the drive roller used in the conveyor belt. Although the rotational force of the roller is reduced, the wear and damage of the conveyor belt is reduced compared to the steel roller, and the manufacturing process is also fully assembled. In particular, the central connector is designed to meet various specifications, and inside the hollow pipe of the cone-shaped belt conveyor return roller. By inserting the bearing (60) around the bearing housing and roller drum fixing bush (50) to be inserted into and combining the dustproof cover (70), dust does not penetrate into the bearing and the inside, and also as a fully assembled manufacturing process As a result, the relationship between the bearing and the bearing is at right angles (90 °) without heat deformation It relates to extend the operating efficiency of the conveyor belt is continuously moving into and life sikimyeo by using a resin material hollow cylindrical drum, and the safety and fire protection, cone belt conveyor return rollers reduces the weight of the roller with improved maintenance efficiency of the equipment.

1 shows a schematic cross-sectional view of a metal drive roller driven by a conveyor belt according to the prior art.

The above-mentioned steel rollers (hereinafter referred to as 'metal rollers') are metal drums with welded seams due to the use of materials produced by bending steel plates in a rounded form on the outer circumferential surface of the steel shaft to form a pipe. drum (20) is formed and bent inward on both sides, connected to the outer drum (20) and the seam (21) by welding, and inserted into the ball-type ball bearing (23) to drive in the circumferential direction I can do it.

10 is a conveyor belt 10 currently generally used throughout the industry is a carrier roller (carrier roller) is installed at the bottom of the transported goods and the return roller is installed and driven in the precious part after transferring the litigation to the destination There are a plurality of return rollers.

The drive roller for the conveyor belt as described above is installed in the precious part after conveying the litigation object to the destination in the state in which the belt conveyor 10 at the top of the carrier roller is bent in a V-shape in using a general pipe having a welded seam. Since the belt conveyor on the top of the return roller is driven in an extended state, the conveyor belt is repeatedly bent and unfolded, and the center of the belt conveyor 10 at the top of the return roller is subject to wear rate due to the weight of the suit. This is said to be the largest.

Due to the continuous operation of the conveyor belt, the hollow drum outside the roller and the hard plates 22 on both sides of the joints 22 are welded and corroded, so that the ball-type ball bearings 23 rotating the drums are removed. In the field where dust is scattered, it is impossible to rotate due to the damage of the bearing 23 due to moisture and dust infiltration, and thus the rubber friction heat of the belt conveyor continuously operated at the top is inserted and inserted into the bearing 23. ) Cannot be fed.

Therefore, since the conveyor belt 10 is made of rubber, the contact part which causes the electronics to fail to detect the rotation improper state due to the damage of the bearing 23 is accompanied by heat generation, which eventually leads to a fire by the flammable material. there is a problem.

Due to the above-mentioned conventional problems, there is a problem in that the frequent replacement of the driving rollers is performed by stopping the conveyor belt 10 that is continuously operated, and productivity is reduced due to the frequent stopping of the continuous operation equipment due to the shortened life. There is a problem.

Therefore, the belt conveyor roller should be installed not only to rotate the roller well, but also to prevent the bearing and the rubber belt of the roller top from being damaged.

In order to solve the problems as described above, an object of the present invention is to adopt a manufacturing method of various parts to the injection process using a resin material to reduce the defect rate according to the uniformity of the accessories and to produce a roller according to the assembly process accordingly In addition, it reduces the frequency of abrasion and fire occurrence of the conveyor belt due to the reduction of rotational force, and the weight due to the specific gravity (weight) difference with the steel is lighter, thereby saving energy due to replacement work and facility operation.

In addition, by inserting an angled outer auxiliary protrusion 71 to the dust cover 70 to remove various contaminants such as primary rainwater, and to form an angled lower dustproof protrusion 72 narrow and obliquely and insert a recess 73 at the top. It is to provide a cone-shaped belt conveyor return roller that does not easily break the bearing by reducing friction resistance and blocking foreign matter by using elasticity.

In addition, another object of the present invention is to protect the conveyor belt by forming a drum of the resin material of the cone-shaped injection process, and the connector of the center is to prepare for a variety of specifications by replacing the specification of the connector and the outer peripheral surface of the drum up and down By providing a trajectory that does not oscillate with the roller, it provides a belt conveyor roller in which impact load is not generated and the bearing is not easily broken.

In order to achieve the above object, the cone-shaped belt conveyor return roller according to the present invention includes a support shaft 40 and both ends 33.36 of the support shaft are inserted into a cone-shaped hollow formed in the axial direction, thereby supporting a central connection support ( Is coupled to 30)

In addition, a pair of bearings are inserted into the inner ring of the bearing housing 51 of each bearing housing and the roller drum fixing bush 50, and a pair of dustproof cover 70 is coupled to the dustproof cover housing 52, and the upper support is supported. Insert the bearing fixing snap-ring into the shaft and bearing correction groove fixing groove 41, and insert the bearing fixing snap-ring into the support shaft in the axially assembled cone-shaped hollow (30.33.36), and fix the assembled bearing housing and roller drum. Bush (50.60.70.) Insert characterized in that the assembly.

Hereinafter, the configuration of the present invention in more detail according to the accompanying drawings.

Cone belt conveyor return roller according to the present invention forms a hollow roll drum (30.33.36) of a non-ferrous metal to a predetermined thickness in order to smoothly drive the conveyor belt as shown in Figs.

As shown in FIG. 3, the resin cone-shaped central roller drum 30 and the cone-shaped left and right roller drums 33.36 were assembled to complete the cone-shaped hollow drum.

In particular, the central roller drum 30 was formed to prepare for various specifications by replacing only the connector.

As shown in FIG. 4, a metal shaft 40 is provided to fix the driving roll drum, and a fixing groove 41 that is detachable / removable is formed at both ends of the shaft to fix the bearing 60. In addition, the bearing 40 is formed on both shafts in the circumferential direction in order to be fixed to the structure fixing member 25 of the conveyor belt to form a detachable groove.

As shown in FIG. 5, a bearing flow bush, a dust cover 70, and a bearing 60 are inserted in the center of the drive roll 30 to smoothly rotate the drive roll. .

As shown in FIG. 7, the outer auxiliary protrusion 71 having an angle of the dust cover and the lower dustproof protrusion 72 having an angle of the dust cover and the lower dustproof protrusion groove 73 having an angle of the dust cover are as shown in FIG. 7. Was formed.

As shown in FIG. 8, the cone-shaped hollow pipe is inserted into the support shaft 40, and then the respective bearing housings and roller drum fixing bushes 50 into which the dustproof cover 70 and the bearing are inserted are inserted into the support shaft. It was constructed by inserting into a hollow hollow pipe.

[Action of invention]
