Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics and transportation, and in particular to a multi-wedge pulley for conveyor rollers. Background Technology
[0002] Roller conveyors are a common type of logistics conveying equipment that transports goods through the rotating motion of rollers. They are widely used in warehousing, manufacturing, express delivery, food and other industries, and are particularly suitable for transporting heavy or regularly shaped items (such as boxes, pallets, etc.).
[0003] Roller conveyors are mainly composed of rollers, supports, drive units, and control systems. In the logistics roller industry, the components supporting the rollers are usually specially designed wedge belt pulleys that drive the long shaft rollers to rotate. The inner diameter of the pulleys, with their rings or reinforcing ribs, fits tightly with the long shaft rollers, and the rotation of the long shaft is achieved through the action of multiple wedge belts, thus realizing the transportation of packages.
[0004] Existing technology, such as the patent announcement number CN214888722U, discloses an integrated multi-wedge pulley assembly, including a wedge pulley. The inner wall of the wedge pulley is uniformly and integrally formed with inner diameter reinforcing ribs, and the outer surface of the wedge pulley is uniformly and integrally formed with wedge grooves. The front surface of the wedge pulley is integrally formed with a honeycomb buffer layer. The honeycomb buffer layer includes fifteen first rectangular support ribs, fifteen second rectangular support ribs, fifteen first arc-shaped support ribs, fifteen third rectangular support ribs, fifteen second arc-shaped support ribs, a conical ring, and a beveled collar. These fifteen sets of superimposed ring arrays form a shock-absorbing layer, which can greatly buffer impact forces from different directions.
[0005] The honeycomb buffer layer of the existing multi-wedge pulley design consists of a ring of triangular perforations and the outer wall of the wedge pulley. Because the triangular structure has strong stability, the supporting ribs of the honeycomb buffer layer are not easily deformed when the multi-wedge pulley is subjected to impact force, and the supporting ribs are easily damaged, thereby reducing the buffering effect. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-wedge pulley for conveying rollers to solve the problems existing in the background art.
[0007] This utility model provides the following technical solution: a multi-wedge pulley for conveying rollers, comprising an integrally formed multi-wedge pulley body, one end of the multi-wedge pulley body being provided with a transmission end connected to the wedge belt, and the other end of the multi-wedge pulley body being provided with a connection end for assembly with the roller, characterized in that: the connection end is provided with a plurality of trapezoidal holes, the plurality of trapezoidal holes being evenly arranged along the circumferential direction of the connection end, and two adjacent trapezoidal holes being spaced apart to form a support partition, the plurality of trapezoidal holes cooperating with the support partition to support the roller.
[0008] Preferably, a limiting ring is provided in the middle of the multi-wedge pulley body, and one end of the transmission end and the connecting end both extend to both sides of the limiting ring. A step is formed at the junction of the transmission end and the limiting ring to block the limiting wedge belt, and a groove is formed at the junction of the connecting end and the limiting ring to limit the assembly distance between the connecting end and the roller.
[0009] Preferably, the transmission end, the connecting end, and the limiting ring are all hollow structures with the same inner diameter, forming a continuous channel. The channel is provided with several limiting strips for connection and assembly with the roller.
[0010] Preferably, the outer surface of the connecting end is provided with a plurality of axial grooves along the axial direction of the multi-wedge pulley, the plurality of axial grooves being equidistantly distributed on the outer surface of the connecting end, and the outer surface of the connecting end is provided with at least one circumferential groove along the circumferential direction of the multi-wedge pulley.

[0012] Preferably, the outer surface of the transmission end is provided with a wedge groove adapted to the wedge belt.
[0013] Preferably, all four corners of the trapezoidal hole are rounded.
[0014] Preferably, the limiting strip has a rectangular structure.
[0015] Preferably, the multi-wedge pulley body is made of one of nylon, polyoxymethylene, or polyetheretherketone.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. The trapezoidal holes provided in this utility model not only effectively reduce the weight of the connecting end, but also, in conjunction with the support plate, give the connecting end a hollow structure. The hollow structure formed by several trapezoidal holes can effectively buffer the impact force of heavy objects on the roller. Moreover, the trapezoidal holes are quadrilateral structures, which, compared to triangular structures, have flexible properties. When the roller is subjected to the pressure of heavy objects, the roller synchronously applies this pressure to the connecting end. At this time, the elastic deformation of the trapezoidal holes achieves buffering, thereby effectively reducing the impact force on the multi-ribbed pulley, preventing damage to the multi-ribbed pulley, and thus improving the service life of the multi-ribbed pulley.
[0018] 2. This utility model adds an axial groove and a circumferential groove to the outer surface of the connecting end. When the connecting end is subjected to pressure and elastic deformation buffering, the wall thickness of the axial groove and circumferential groove of the connecting end is relatively thin, so that the connecting end is easy to undergo elastic deformation for buffering. In addition, the axial groove and circumferential groove form gaps on the surface of the connecting end, which effectively prevents the connecting end from being easily squeezed and damaged.

Detailed Implementation
[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0025] This utility model provides a multi-wedge pulley for conveyor rollers, such as... Figure 1-4 As shown, the multi-ribbed pulley body 100 is integrally formed. Specifically, one end of the multi-ribbed pulley body 100 is provided with a transmission end 101 that is connected to the wedge belt, the other end of the multi-ribbed pulley body 100 is provided with a connection end 102 that is assembled with a roller, and a limit ring 103 is provided in the middle of the multi-ribbed pulley body 100.
[0026] Furthermore, one end of the transmission end 101 and the connecting end 102 both extend to both sides of the limiting ring 103. The transmission end 101, the connecting end 102, and the limiting ring 103 are all hollow structures with the same inner diameter, forming a continuous channel. Inside the channel, there are several limiting strips 104 for connection and assembly with the roller. The limiting strips 104 are rectangular structures, and the overall outline of the rectangular structure is horizontal and consistent, making it easy to manufacture and process.
[0027] The limiting strip 104 not only strengthens the forming strength of the transmission end 101, the connecting end 102, and the limiting ring 103, but also adapts to the limiting structure inside the roller and is used to assemble the multi-wedge pulley body 100 onto the roller.
[0028] When assembling with the roller, one end of the connecting end 102 is inserted into the inside of the roller, and the limiting strip 104 is inserted to match the limiting structure inside the roller. Under the action of the limiting strip, the roller and the multi-wedge pulley body rotate synchronously.
[0029] Furthermore, a plurality of trapezoidal holes 1021 are provided on the connecting end 102. One end of the trapezoidal hole 1021 extends to the lower part of the limiting ring 103. The plurality of trapezoidal holes 1021 are evenly arranged along the circumferential direction of the connecting end 102, and two adjacent trapezoidal holes 1021 are spaced apart to form a support partition 1022. The plurality of trapezoidal holes 1021 cooperate with the support partition 1022 to support the roller.
[0030] Specifically, the side of the trapezoidal hole 1021 near the outer edge of the connecting end 102 is larger than the side of the trapezoidal hole 1021 near the inner edge of the connecting end 102, and the two sides are tilted symmetrically, thus forming a trapezoidal quadrilateral structure.
[0031] Furthermore, the four corners of the trapezoidal hole 1021 are all provided with rounded corners 10211. The rounded corners 10211 can improve the elastic force of the trapezoidal hole 1021 during elastic deformation, and at the same time facilitate the forming and processing of the multi-wedge pulley body 100.
[0032] The trapezoidal hole 1021 not only effectively reduces the weight of the connecting end, but also, in conjunction with the support plate 1022, gives the connecting end 102 a hollow structure. The hollow structure formed by several trapezoidal holes 1021 can effectively buffer the impact force of heavy objects on the roller. Moreover, the trapezoidal hole 1021 is a quadrilateral structure, which, compared to a triangular structure, has the property of flexibility. When the roller is subjected to the pressure of heavy objects, the roller synchronously applies this pressure to the connecting end 102. At this time, the elastic deformation of the trapezoidal hole 1021 achieves buffering, thereby effectively reducing the impact force on the multi-ribbed pulley, preventing damage to the multi-ribbed pulley, and thus improving the service life of the multi-ribbed pulley.
[0033] In this embodiment, a groove 106 is formed at the junction of the connecting end 102 and the limiting ring 103 to limit the assembly distance between the connecting end 102 and the roller. When the multi-ribbed pulley body 100 is assembled on the roller, the connecting end 102 is inserted into the inside of the roller until the roller abuts against the surface of the groove 106, so that the positions of a row of multi-ribbed pulley bodies 100 are consistent and correspond, which facilitates the subsequent assembly of the wedge belt.
[0034] In this embodiment, the outer surface of the transmission end 101 is provided with a wedge groove 1011 that is adapted to the wedge belt. A step 105 is formed at the junction of the transmission end 101 and the limiting ring 103 to block and limit the wedge belt. When assembling the wedge belt, the wedge belt is sleeved on the wedge groove 1011 on the transmission end, and the side of the wedge belt contacts the step 105, so that the step 105 limits the position of the wedge belt, so that the wedge belt corresponds to the main body 100 of the multi-wedge pulley in a row, which facilitates the assembly operation of the wedge belt.
[0035] In this embodiment, the outer surface of the connecting end 102 is provided with four axial grooves 1023 along the axial direction of the multi-wedge pulley. The four axial grooves 1023 are equidistantly distributed on the outer surface of the connecting end 102. Specifically, the cross-section of the axial grooves 1023 is a V-shaped structure. When the connecting end 102 is subjected to compressive elastic deformation buffering, the wall thickness at the position of the axial grooves 1023 of the connecting end 102 is relatively thin, thereby making it easy for the connecting end 102 to undergo elastic deformation for buffering. At the same time, the axial grooves 1023 form gaps on the outer surface of the connecting end 102, making the connecting end 102 less prone to extrusion damage.
[0036] In this embodiment, the outer surface of the connecting end 102 is provided with a circumferential groove 1024 along the circumferential direction of the multi-wedge pulley. Specifically, the cross-section of the circumferential groove 1024 is also a V-shaped structure. When the connecting end 102 is subjected to compressive elastic deformation buffering, the wall thickness at the axial groove 1023 position of the connecting end 102 is relatively thin, thereby making the connecting end 102 easy to undergo elastic deformation. At the same time, the circumferential groove 1024 forms a gap on the outer surface of the connecting end 102, further preventing the connecting end 102 from being easily crushed and damaged.
[0037] In this embodiment, the multi-ribbed pulley body 100 is made of nylon. Nylon has high strength, wear resistance, impact resistance, and good self-lubricating properties, making it suitable for high-load and high-speed applications. Other wear-resistant, high-temperature-resistant, and high-strength plastics can also be used, such as polyoxymethylene (POM) or polyetheretherketone (PEEK). POM has excellent mechanical strength, rigidity, and fatigue resistance, while PEEK has extremely high heat resistance, chemical stability, and mechanical strength. Reinforced plastics can also be used; for example, adding reinforcing materials such as glass fiber to plastics can significantly improve their strength, rigidity, and heat resistance.
