Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a supporting roller assembly of a conveyor belt. Background Art

[0002] The conveyor belt is a continuous conveying mechanical component widely used in material transportation. Its main function is to use the continuous circular motion of the conveyor belt to achieve continuous or intermittent transportation of materials.

[0003] The support roller assembly is used to support and properly pull the conveyor belt. The support roller assembly usually includes a frame, a drive roller 1 and a drive roller 2. The drive roller 1 and the drive roller 2 are movably connected at both ends of the frame respectively. The conveyor belt is sleeved on the drive roller 1 and the drive roller 2. When the drive roller continues to rotate under the action of the driving member, the conveyor belt can move along with it.

[0004] Support roller 1 and support roller 2 are usually cylindrical, and the conveying surface on the upper part of the conveyor belt is flat. The conveyed material easily slides off the upper part of the conveyor belt, resulting in poor conveying stability. Summary of the Invention

[0005] The purpose of the utility model is to provide a support roller assembly for a conveyor belt with high stability and compact structure in order to solve the above problems in the prior art.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A support roller assembly for a conveyor belt comprises a frame, and is characterized in that it also comprises a drive roller 1, a drive roller 2 and a plurality of transition roller assemblies, wherein the drive roller 1 and the drive roller 2 are axially fixed at both ends of the frame respectively and the drive roller 1 and the drive roller 2 are parallel to each other, and the plurality of transition roller assemblies are adjacently and evenly arranged between the drive roller 1 and the drive roller 2 and connected to the frame, and after the conveyor belt is sleeved on the drive roller 1 and the drive roller 2, the transition roller assembly can support the bottom of the conveyor belt and cause the cross section of the conveyor belt at the transition roller assembly to be bent into a V shape.

[0008] The support roller assembly of the conveyor belt creatively arranges a plurality of transition roller assemblies between the first transmission roller and the second transmission roller.

[0009] Since the first transmission roller and the second transmission roller are cylindrical, the conveying portion of the conveyor belt located between the first transmission roller and the second transmission roller is also planar.

[0010] However, several transition roller assemblies act on the lower part of the conveyor belt, so the cross-section of the conveyor belt between the transmission rollers 1 and 2 is V-shaped. The material is located in the V-shaped notch of the conveyor belt, so the conveyed material has a relatively high stability and is unlikely to fall off the conveyor belt.

[0011] In the above-mentioned support roller shaft assembly of the conveyor belt, the transition roller assembly includes a base, support roller one, support roller two and support roller three. The above-mentioned support roller one is arranged parallel to the transmission roller one and the support roller one is axially fixed on the base. The above-mentioned support roller two is arranged obliquely and the lower end of the oblique part is connected to one end of the base. The above-mentioned support roller three is arranged obliquely and the lower end of the oblique part is connected to the other end of the base.

[0012] Support roller 1 is used to support the middle of the conveyor belt, and support roller 2 and support roller 3 are used to support the two edges of the conveyor belt at an angle.

[0013] Obviously, under the action of the support roller 1, the support roller 2 and the support roller 3, the cross section of the conveyor belt at this location is V-shaped.

[0014] In the above-mentioned support roller assembly of the conveyor belt, the base includes a main body, a connection part 1 and a connection part 2. The above-mentioned main body is in sheet shape and is fixedly connected to the frame surface in contact. The above-mentioned connection part 1 and connection part 2 are respectively located at the two ends of the main body. The number of bases in the same transition roller assembly is two, and the two ends of the support roller 1 are respectively connected to one connection part of the corresponding base, the support roller 2 is connected to the connection part 2 of one of the bases, and the support roller 3 is connected to the connection part 2 of the other base.

[0015] Such a structure can stably connect the support roller one, the support roller two and the support roller three to the base.

[0016] In the above-mentioned support roller shaft assembly of the conveyor belt, the support roller 2 and the support roller 3 are symmetrically arranged at both ends of the support roller 1.

[0017] The supported conveyor belt can also be symmetrical on both sides.

[0018] The support roller shaft assembly of the above-mentioned conveyor belt also includes a rod-shaped and obliquely arranged connecting rod 1, the connecting part 2 is sheet-shaped, the above-mentioned support roller 2 is sleeved on the upper part of the connecting rod 1 and the two are axially fixed, and the lower part of the above-mentioned connecting rod is in contact with the two surfaces of the connecting part and the two are connected.

[0019] The supporting roller can be stably connected to the base through the connecting rod.

[0020] In the above-mentioned support roller assembly of the conveyor belt, the connecting part 2 has a penetrating positioning hole 1, and the connecting part 2 also has a plurality of positioning holes 2 evenly distributed adjacent to each other with the positioning hole 1 as the center. The fastener passing through one of the positioning holes is connected to the connecting rod 1, and the fastener passing through any one of the positioning holes 2 is connected to the connecting rod 1.

[0021] When the inner end of the connecting rod 1 is connected to different positioning holes 2, the connecting rod 1 can be properly swung, thereby changing the inclination angle of the supporting roller 2 according to actual conditions.

[0022] The support roller shaft assembly of the above-mentioned conveyor belt also includes a rod-shaped and obliquely arranged connecting rod 2, the connecting part 2 is sheet-shaped, the above-mentioned support roller 3 is sleeved on the upper part of the connecting rod 2 and the two are axially fixed, and the lower part of the above-mentioned connecting rod 2 is in contact with the connecting part 2 surface and the two are connected.

[0023] In the above-mentioned support roller assembly of the conveyor belt, the connecting part 2 has a penetrating positioning hole 1, and the connecting part 2 also has a plurality of positioning holes 2 evenly distributed adjacent to each other with the positioning hole 1 as the center. The fastener passing through one positioning hole is connected to the connecting rod 2, and the fastener passing through any one of the positioning holes 2 is connected to the connecting rod 2.

[0024] The function of connecting rod 2 is the same as that of connecting rod 1. Therefore, the structural relationship between connecting rod 2 and supporting roller 3 will not be described in detail in the specification.

[0025] In the above-mentioned support roller assembly of the conveyor belt, the frame includes frame one and frame two, the inner end of the frame one and the inner end of the frame two are detachably connected, the drive roller one is connected to the outer end of the frame one, and the drive roller two is connected to the outer end of the frame two.

[0026] Since rack 1 and rack 2 are connected in series, the entire rack is relatively long. After disassembly, rack 1 and rack 2 can be separated. The separate racks 1 and 2 take up less space, so disassembly facilitates logistics, transportation or storage.

[0027] In the above-mentioned support roller assembly of the conveyor belt, the inner end of the frame one and the inner end of the frame two are hinged by a pin shaft, the frame one has a protruding positioning part one, and the frame two has a protruding positioning part two. When the frame one and the frame two are aligned in a straight line, the above-mentioned positioning part one is in surface contact with the positioning part two.

[0028] Under the action of the pin shaft, the inner end of frame one and the inner end of frame two can be stably hinged together. Once the positioning part one contacts the positioning part two, frame one and frame two are connected flush, thereby forming a frame with a relatively long length.

[0029] In the above-mentioned support roller assembly for the conveyor belt, the first positioning portion and the second positioning portion are provided with fasteners capable of locking and connecting the two.

[0030] After the fasteners are connected to the first positioning portion and the second positioning portion, the first frame and the second frame can be stably connected together.

[0031] Compared with the existing technology, the support roller shaft assembly of the conveyor belt can form a V-shaped cross-section of the conveyor belt between the drive roller 1 and the drive roller 2 under the action of the transition roller assembly. Therefore, the material is embedded in the V-shaped notch of the conveyor belt during the transmission process, preventing the material from falling and effectively improving the transportation stability.

[0032] At the same time, the support roller assembly includes a centrally arranged base, a support roller 1, a support roller 2 and a support roller 3, so its structure is relatively compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
