Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transportation, in particular to a friction upper centering roller structure. Background Art

[0002] Rollers are important components of belt conveyors. They come in many types and large quantities. They can support the weight of the conveyor belt and materials. They account for 35% of the total cost of a belt conveyor and generate more than 70% of the resistance. Therefore, the quality of the rollers is particularly important. The inclination angle of existing self-aligning rollers is difficult to adjust after they are produced. Most of them are fixed, which makes it inconvenient to change the surface shape of the conveyor belt according to the transported objects, cannot adapt well to the transported objects, and are not practical.

[0003] When the rollers adjust their angles, the conveyor belt will bend and the edges will easily warp. When transporting hard and small objects such as ore and coal, they will easily fall under the conveyor belt, causing damage to the rollers, reducing their service life and making them less practical.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] Reference Figure 1-5 A friction upper centering roller structure includes a support plate 1, a slide groove 2 is provided on the left and right sides of the upper surface of the support plate 1, a slider 3 is slidably connected to the outer surface of the slide groove 2, a hinge seat 4 is provided at the top of the slider 3, a cylinder 5 is hinged on the outer surface of the hinge seat 4, a connecting plate 1 6 is fixedly connected to the edge of the upper surface of the cylinder 5, a connecting plate 1 6 is movably connected to the inner wall of the connecting plate 1 6, and a roller 23 is provided on the right side of the connecting plate 2 7;

[0024] Limiting plates 8 are fixedly installed at the edges of both front and rear sides of the upper surface of the support plate 1 . A limiting groove 9 is provided on the upper surface of the limiting plate 8 , and a limiting frame 10 is inserted into the limiting groove 9 .

[0025] Most of the existing equipment is fixed and difficult to adjust the angle. When transporting goods, the angle of the roller cannot be adjusted according to the volume and shape of the goods, which affects the efficiency of the belt conveyor in transporting goods and reduces its practicality.

[0026] When the operator uses the equipment to work, he first lifts the limit frames 10 on the front and rear sides of the hinge seat 4, and then moves the hinge seat 4 backward through the slide 2 and the slider 3 to the appropriate position, and then inserts the limit frames 10 on the front and rear sides of the hinge seat 4 into the limit grooves 9 on the limit plate 8 and the groove on the surface of the support plate 1, and then lifts the roller 23 upward through the operation of the cylinder 5, so that the roller 23 forms an angle with the horizontal plane, and the goods can be transported according to the volume and shape of the goods, thereby improving the work efficiency of transportation and increasing practicality.

[0027] Example 2

[0028] Improvement based on Example 1: a friction upper centering roller structure, a bracket 11 is provided in the middle position of the upper surface of the connecting plate 2 7, a fixed plate 12 is provided on the inner wall on the right side of the bracket 11, a base 13 is provided at the edge of the lower surface of the fixed plate 12, a spring 14 is provided on the lower surface of the base 13, a connecting block 15 is provided at the bottom end of the spring 14, a connecting rod 16 is provided in the middle position on the right side of the connecting block 15, a positioning wheel 17 is provided in the middle position of the outer surface of the connecting rod 16, support columns 18 are fixedly connected to the four corners of the lower surface of the support plate 1, a bottom plate 19 is fixedly connected to the middle position of the upper surface of the support plate 1, a load-bearing frame 20 is fixedly connected to the left and right sides of the upper surface of the bottom plate 19, a curved connecting plate 21 is fixedly connected to the right side of the support column 18, and a square plate 22 is fixedly connected to the bottom end of the support column 18.

[0029] When the operator adjusts the angle of the roller 23, it is very likely to cause the edge of the conveyor belt of the belt conveyor to warp up, which may cause the transported goods to fall during transportation. After the warp up, it takes manpower to flatten the warped part, which increases the workload of the operator and is not conducive to the operation of the belt conveyor.

[0030] When the operator uses the equipment to work, after adjusting the roller 23 to a suitable angle, the bracket 11 and the connecting plate 6 are fixedly connected. When the connecting plate 6 is tilted, the bracket 11 will also tilt, so that the positioning wheel 17 is always on the surface of the conveyor belt, and the conveyor belt can be positioned all the time, avoiding the edge of the conveyor belt from tilting when adjusting the angle, and avoiding the goods falling on the surface of the roller and causing damage to the roller, thereby extending the service life of the roller and improving the efficiency of transporting goods.

[0031] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
