Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of conveyor belt structures, specifically to a corner structure for an inclined conveyor belt. Background Technology
[0002] Conveyor belts, also known as conveyor belts, are widely used in industrial applications. They are typically used for handling materials or objects placed in boxes or pallets, as well as for transporting large quantities of goods or agricultural products in bulk. Depending on the specific needs, the interconnected equipment usually consists of belt conveyors or chain conveyors. The conveying surface is mostly composed of several spaced conveyor rollers. Depending on the conveyed material, some conveyor belt equipment will have a conveying surface covered with rubber or similar material, which circulates synchronously with the conveying surface. In inclined conveyor systems, to prevent materials or objects from slipping, the tilt angle of the conveyor belt is usually limited. Chain conveyors are generally used to ensure stability, especially for heavier items. However, during use, especially at high speeds, chains are prone to jumping at the connection points. This is because the operating forces cause stretching and deformation, leading to loosening, tooth breakage, and jumping out. Therefore, chains usually require testing and maintenance to maintain proper tension during transmission. In addition, due to the change in the direction of force at the corner position, the conveyor rollers of the inclined conveyor belt are also prone to vibration after long-term use, which will further accelerate the jumping and deformation of the chain. Utility Model Content
[0003] To address the problems existing in the prior art, the present invention aims to provide a corner structure for an inclined conveyor belt. This invention is applied to inclined conveyor equipment, ensuring a stable connection of the conveyor surface, smooth transmission, easy chain tightening, and stable force distribution.
[0004] The present invention discloses a slope-type conveyor belt corner structure, comprising a first conveyor surface spliced with a horizontal conveyor belt and a second conveyor surface spliced with a slope conveyor belt. A drive shaft is provided at the connection between the first and second conveyor surfaces. A plurality of first conveyor rollers with gears are arranged on the first conveyor surface, and a plurality of second conveyor rollers with gears are arranged on the second conveyor surface. The drive shaft is linked to the first and second conveyor rollers respectively via different chains. An adjustment mechanism is also provided below the second conveyor surface, and the adjustment mechanism is linked to the second conveyor rollers, thereby causing the second conveyor surface to be tightened downward by force.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0018] like Figure 1 and Figure 2As shown, the present invention discloses a slope-type conveyor belt corner structure, including a first conveyor surface 1 spliced with a horizontal conveyor belt and a second conveyor surface 2 spliced with a slope conveyor belt. A drive shaft 3 is provided at the connection between the first conveyor surface 1 and the second conveyor surface 2. A plurality of first conveyor rollers 11 with gears are arranged on the first conveyor surface 1, and a plurality of second conveyor rollers 21 with gears are arranged on the second conveyor surface 2. The drive shaft 3 is linked to the first conveyor rollers 11 and the second conveyor rollers 21 respectively through different chains. An adjustment mechanism is also provided below the second conveyor surface 2. The adjustment mechanism is linked with the second conveyor rollers 21, thereby causing the second conveyor surface 2 to be tightened downward by force. This invention is applied to a conveying device for climbing and lifting. First, it links two conveying surfaces through the same drive shaft 3 to ensure a stable connection between the conveying surfaces and a relatively synchronous conveying mode, so that the transmission is smooth and the force is even. The two conveying surfaces can extend in their respective plane directions or be spliced with other conveyor belts. The adjustment mechanism mainly tightens the second conveying surface 2, which is not horizontal. It uses the downward pulling force on the second conveying roller 21 to reduce the vibration of the second conveying surface 2, relatively fixes the tilt angle of the conveying surface, and can also be used to tighten the chain, extend its service life, and make the force more stable.
[0019] Specifically, the adjustment mechanism includes a housing 4 fixed below the second conveying surface 2. A fixing frame 5 is mounted on the bottom of the housing 4, and a tensioning wheel 6 is mounted on the fixing frame 5. A first rotating shaft 7 and a second rotating shaft 8 are also mounted inside the housing 4, and the first rotating shaft 7 and the second rotating shaft 8 are respectively located below both ends of the second conveying surface 2. The tensioning wheel 6 is linked to the first rotating shaft 7, the second conveying roller 21, and the second rotating shaft 8 sequentially via a chain. Figure 2As shown, this device has at least three first conveyor rollers 11 or two second conveyor rollers 21 at the corner of the conveyor belt, and the distance between the first rotating shaft 7 and the second rotating shaft 8 needs to be greater than the position of these three second conveyor rollers 21 so that the chain can be spread open and the tensioning wheel 6 can provide downward pulling force. There are at least two connection methods here. One is that the chain linking the drive shaft 3 and the second transmission roller 21 can directly bypass the first rotating shaft 7 and the second rotating shaft 8 for appropriate tightening. The chain leading from the tightening wheel 6 passes through the first rotating shaft 7, the second transmission roller 21, and the second rotating shaft 8 in sequence and returns to the tightening wheel 6. At this time, the chain on the tightening wheel 6 only provides downward pulling force on the second transmission roller 21 and the second transmission surface 2 to prevent the second transmission surface 2 from shaking and stabilize its tilt angle. The other is that the chain starts from the drive shaft 3, passes around the second transmission roller 21 from the top, and is led to the top and inside of the second rotating shaft 8. Then it passes around the tightening wheel 6 and returns to the drive shaft 3 from the inside and top of the first rotating shaft 7. That is, while the chain tightens and drives the second rotating shaft 8 to transmit, a V-shaped chain path is formed below the second transmission surface 2. Similarly, the tightening wheel 6 is pulled downward to maintain the tension of the chain and make the second transmission surface 2 bear the force downward, making it less prone to shaking.
[0020] Furthermore, for ease of maintenance and adjustment, the tensioning wheel 6 is rotatably connected to the mounting base 9, which is threadedly connected to the fixing frame 5 via a screw, allowing the mounting base 9 to be adjusted vertically relative to the fixing frame 5. The tensioning wheel 6, connected to the mounting base 9 via a thread, allows for real-time adjustment of its downward tension, adjusting its vertical position relative to the fixing frame 5 according to the chain length and tension requirements. Additionally, there are four tensioning wheels 6, each corresponding to a gear on the second transmission roller 21. The gears on the first rotating shaft 7 and the second rotating shaft 8 are located near the ends, respectively. This arrangement allows for the simultaneous application of both connection methods. The gear positions on the first rotating shaft 7 and the second rotating shaft 8 are primarily adapted to their linkage with the tensioning wheels 6 and correspond to the forces at both ends of the second transmission roller 21. The middle position only needs to bypass the chain without using gears to limit the chain, avoiding excessive restriction that could cause self-locking.
[0021] In one embodiment, the gear positions on the first conveyor roller 11 and the gear positions on the second conveyor roller 21 are staggered, and at least two chains are arranged side by side at each gear position. Since the first conveyor surface 1 and the second conveyor surface 2 are both synchronously conveyed by the drive shaft 3, they need to be separated to facilitate the arrangement of the chains, and two chain connection positions are reserved at each position to provide higher stability and safety for the transmission.
[0022] In one embodiment, a tensioning rod 12 is provided below the end of the first conveying surface 1 away from the second conveying surface 2. The tensioning rod 12 is linked to the chain connecting the drive shaft 3 and the first conveying roller 11. Both ends of the tensioning rod 12 are rotatably connected to slide blocks 13, which can slide up and down along the side of the first conveying surface 1 and lock their relative positions. For the horizontal first conveying surface 1, although the chain jump is not obvious, it is still necessary to maintain appropriate tension of the chain to prevent aging after long-term use. Therefore, this device uses slide blocks 13 to slide and fix on the side below the first conveying surface 1 to adjust and pull the tensioning rod 12 downward, thereby causing the linkage chain of the drive shaft 3 and the first conveying roller 11 to pass around the tensioning rod 12 and tighten it.
[0023] Furthermore, the first conveying surface 1 and the second conveying surface 2 are rotatably connected around the drive shaft 3 as the central axis. The drive shaft 3, the first conveying roller 11, and the second conveying roller 21 are all mounted on the first conveying surface 1 and / or the second conveying surface 2 via bearing seats at both ends. The second conveying surface 2 is an inclined surface, and its inclination angle relative to the horizontal plane of the first conveying surface 1 can be adjusted by rotation during installation. After locking, the aforementioned adjustment mechanism further prevents it from shaking. The connection between the drive shaft 3, the first conveying roller 11, and the second conveying roller 21 needs to be linked with the chain for rotation, and can be tightened and locked to the corresponding side positions of the two conveying surfaces by means of connection such as bearing seats.
