Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor rollers, in particular to a high-efficiency belt conveyor roller which is not prone to deviation. Background Art

[0002] The belt conveyor roller is an important component of the belt conveyor. Its main function is to support the weight of the conveyor belt and materials, reduce the sag of the conveyor belt, and enable it to run stably. When the drive motor of the belt conveyor is started, the power is transmitted to the roller through the transmission mechanism, causing the roller to start rotating; the friction between the roller and the conveyor belt drives the conveyor belt to move, thereby realizing the transportation of materials.

[0003] In the prior art, the traditional belt conveyor roller is a simple cylindrical roller that plays the sole function of driving the conveyor belt to rotate. If the material on the belt is unevenly distributed during transportation, the excessive load on one side may cause the belt to deviate to one side. At the same time, the worn or damaged roller and belt may lose their original balance and cause the belt to deviate, thereby causing the material transportation to deviate, so that the offset belt side will rub against the frame for a long time and cause wear. How to invent an efficient belt conveyor roller that is not prone to deviation to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a high-efficiency belt conveyor roller that is not prone to deviation, aiming to improve the problem of deviation of the traditional belt conveyor roller belt, which causes the side of the belt to rub against the frame for a long time and cause wear.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a roller for an efficient belt conveyor which is not prone to deviation, comprising a roller body and a mounting frame arranged on the roller body, wherein the outer wall of the roller body is provided with a plurality of equidistant anti-skid grooves, the outer walls of both ends of the roller body are provided with mounting grooves, and the inner wall of one side of the mounting groove is provided with an annular groove;

[0007] The inner wall of the mounting bracket is rotatably connected to the outer wall of the mounting groove, a spring is provided at one end of the mounting bracket close to the annular groove, a limiting ring is provided at the other end of the spring, an outer wall of one end of the limiting ring is rotatably connected to the inner wall of the annular groove, a baffle is fixedly connected to an outer wall of one side of the mounting bracket, one end of the mounting bracket is fixedly connected to a limiting rod, a fixing block is installed on the outer wall of the limiting rod, and one end of the fixing block is fixedly connected to a fixing bracket.

[0008] Preferably, two ends of the spring are fixedly connected to the mounting frame and one side of the limiting ring respectively, and the inner wall of the limiting ring is rotatably connected to the outer wall of the mounting groove.

[0009] Preferably, an oblique groove is provided on the upper outer wall of the baffle, and a plurality of upper balls are rollingly connected to the inner wall of the lower end of the baffle.

[0010] Preferably, a limiting groove slidably connected to the outer wall of the limiting rod is provided on the fixing block, and the fixing frame is fixed to the frame of the conveyor belt by bolts.

[0011] By adopting the above technical solution, the friction coefficient of the belt during transmission is increased by the anti-skid groove to prevent slipping. At the same time, the mounting frame arranged on the side of the belt cooperates with the spring to limit it, thereby preventing the belt from deviating during transmission.

[0012] Preferably, a lubrication cavity is provided inside the mounting frame, a partition is fixedly connected to the inner wall of the lubrication cavity, and one side of the partition is an inclined surface.

[0013] Preferably, a plurality of piston rods slidably connected to the inner wall of the lubrication cavity are fixedly connected to an outer wall of one side of the fixed block.

[0014] Preferably, one end of the piston rod is fixedly connected to a sealing plate, an outer wall of the sealing plate is fixedly connected to a sealing ring, and a sealing plug is installed on the inner wall of the upper end of the lubrication cavity.

[0015] Preferably, the mounting frame is fixedly connected to the inner wall of the lubrication cavity close to a plurality of rolling-connected side balls.

[0016] By adopting the above technical solution, when the belt deviates, one side of it contacts the surface of the side ball. When the belt continues to deviate, the mounting frame is squeezed and moved outward. At this time, the sealing plate moves toward the inside of the lubrication cavity, and the lubricating liquid inside is squeezed through the gap above the partition and falls onto the side ball on one side, thereby cooperating with the transmission belt to improve the transmission effect and avoid greater wear on the belt when it deviates.

[0017] The beneficial effects of the utility model are:

[0018] The upper ball roller is arranged to contact the belt during belt transmission, so as to prevent the upper side of the belt from directly contacting the upper baffle and causing wear. At the same time, the side ball rollers are arranged to press against part of the side of the belt when the belt deviates, so as to reduce the size of the contact surface and thus reduce the friction generated by subsequent transmission, so as to prevent the entire side of the belt from directly pressing against the outer wall of the mounting frame to slide and cause greater wear. At the same time, the sealing plate is arranged to push the lubricating oil on one side of the lubrication chamber when the belt deviates at a large angle, so that the lubricating oil enters the other side of the partition to lubricate the side ball rollers below, and the lubricating oil is applied to the side of the belt through contact during the transmission of the belt, so as to reduce the friction between the side ball rollers and the side of the belt, so as to avoid wear caused by large friction during the belt transmission process, and the spring cooperates with the mounting frame to give a reverse force after the belt deviates, continuously pushes one side of the belt to make it return to the correct position, corrects and restores the belt, so as to avoid wear between the side and the mounting frame caused by the deviation of the belt during operation.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example, see Figure 1-Figure 8 A high-efficiency belt conveyor roller that is not prone to deviation comprises a roller body 1 and a mounting frame 5 arranged on the roller body 1, a plurality of equally spaced anti-skid grooves 2 are provided on the outer wall of the roller body 1, mounting grooves 3 are provided on the outer walls at both ends of the roller body 1, and an annular groove 4 is provided on the inner wall of one side of the mounting groove 3;

[0031] The inner wall of the mounting frame 5 is rotatably connected to the outer wall of the mounting groove 3. A spring 6 is provided at one end of the mounting frame 5 close to the annular groove 4. A limiting ring 7 is provided at the other end of the spring 6. The outer wall of one end of the limiting ring 7 is rotatably connected to the inner wall of the annular groove 4. A baffle 9 is fixedly connected to the outer wall of one side of the mounting frame 5. A limiting rod 8 is fixedly connected to one end of the mounting frame 5. A fixing block 19 is installed on the outer wall of the limiting rod 8. A fixing frame 18 is fixedly connected to one end of the fixing block 19.

[0032] Furthermore; the two ends of the spring 6 are fixedly connected to the mounting frame 5 and one side of the limiting ring 7 respectively, the inner wall of the limiting ring 7 is rotatably connected to the outer wall of the mounting groove 3, and it is characterized in that an inclined groove is provided on the upper outer wall of the baffle 9, and a plurality of upper balls 10 are rollingly connected to the inner wall of the lower end of the baffle 9, a limiting groove 20 is provided on the fixing block 19 and is slidably connected to the outer wall of the limiting rod 8, and the fixing frame 18 is fixed to the frame of the conveyor belt by bolts.

[0033] It should be noted that: in the process of the belt being transmitted through the roller body 1, the friction coefficient is increased by the anti-skid groove 2 opened on the surface of the roller body 1, and the probability of the belt running off track is reduced. The upper ball 10 arranged at the lower end of the baffle 9 limits the belt and reduces the wear of the belt. When the belt runs off track, one side of its outer wall presses against the mounting frame 5 to stretch the spring 6 to move toward one end of the roller body 1. At the same time, the spring 6 gives the belt a reaction force, so that the mounting frame 5 presses against the belt and slowly corrects it during the subsequent transmission process.

[0034] Furthermore, a lubrication cavity 11 is opened inside the mounting frame 5, and a partition 12 is fixedly connected to the inner wall of the lubrication cavity 11, one side of the partition 12 is an inclined surface, and a plurality of piston rods 13 slidably connected to the inner wall of the lubrication cavity 11 are fixedly connected to the outer wall of one side of the fixed block 19, and a sealing plate 14 is fixedly connected to one end of the piston rod 13, and a sealing ring 15 is fixedly connected to the outer wall of the sealing plate 14, and a sealing plug 17 is installed on the inner wall of the upper end of the lubrication cavity 11, and a plurality of side balls 16 are fixedly connected to the inner wall of the lubrication cavity 11 of the mounting frame 5.

[0035] It should be noted that: when one side of the belt deviates, it contacts the side ball 16 at one end of the mounting frame 5, and during the transmission process, the side ball 16 is matched to make it roll, thereby reducing the contact area and thus reducing the wear on the side of the belt. At the same time, when the belt deviates at a large angle, it moves outward against the mounting frame 5. At this time, the sealing plate 14 moves toward the inside of the lubrication cavity 11, and squeezes the lubricating fluid inside through the gap above the partition 12 and falls onto the side ball 16 on one side. While the side ball 16 rolls, the lubricating fluid is evenly applied to the side of the belt to avoid greater wear on the belt when it deviates.

[0036] The working principle of this high-efficiency belt conveyor roller that is not prone to deviation:

[0037] Take out the sealing plug 17 and add lubricating oil to the lubrication chamber 11 between the partition 12 and the sealing plate 14, and fill it when the subsequent lubrication is insufficient. After filling, insert the sealing plug 17. In the process of the belt passing through the roller body 1 for transmission, the anti-skid groove 2 opened on the surface of the roller body 1 is used to increase the friction coefficient and reduce the probability of the belt running off. The upper ball 10 arranged at the lower end of the baffle 9 limits the upper end of the belt while preventing the belt from directly contacting the upper baffle 9 to cause wear. When the belt runs off, the outer wall of one side contacts the side ball 16 at one end of the mounting frame 5, and drives the side ball 16 to roll during the belt transmission process to prevent the side wall of the belt from directly squeezing the outer wall of the mounting frame 5 to generate a large friction force, thereby preventing the belt from sliding with the outer wall of the mounting frame 5 during the transmission process and causing wear. At the same time, when the belt runs off at a large angle, one side of the belt squeezes the side ball 16 to push the mounting frame 5 to move outward. At the same time, the partition 12 in the lubrication chamber 11 and the mounting frame 5 slide synchronously. At this time, the partition 12 moves toward one side of the sealing plate 14. During the movement, the space between the sealing plate 14 and the partition 12 gradually decreases, so that the lubricating oil level between the partition 12 and the sealing plate 14 gradually rises. When the lubricating oil level is higher than the partition 12, the lubricating oil falls into the lubricating cavity 11 on the other side of the partition 12 through the gap between the partition 12 and the lubricating cavity 11. At this time, the lubricating oil enters the gap between the side ball 16 and the lubricating cavity 11 to lubricate the side ball 16. At the same time, when the belt is driving, its side squeezes the side ball 16 to roll, so that the lubricating oil is evenly applied to the side ball The outer wall of the ball 16 is pressed against the outer wall of the ball 16, and the lubricating oil is evenly applied to the side of the belt while the side ball 16 rolls, thereby reducing the friction between the side of the belt and the side ball 16, thereby reducing the wear of the belt. At the same time, in the process of belt deviation transmission, the spring 6 drives the mounting frame 5 to give the belt a reaction force, so that the side ball 16 on one side of the mounting frame 5 presses against the belt to make it slowly return to the center in the subsequent transmission process, effectively avoiding the deviation of the belt during transmission, and preventing the direct contact between the side of the belt and the frame during the deviation to cause wear.

[0038] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
