Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor with unilateral lifting capability, specifically a unilateral lifting belt conveyor and conveying system. Background Technology

[0002] Belt conveyors are a common type of material conveying equipment, typically consisting of a frame, rollers, and a conveyor belt. The rollers drive the conveyor belt to rotate, thereby conveying the material on the conveyor belt.

[0003] In practical applications, to meet the requirements of long-distance conveying, multiple conveyors are often used in relay mode. For example, when conveying bagged materials, a feeding conveyor feeds the bagged material to a receiving conveyor, which then transports the bagged material to the receiving station. This method is suitable when the material handling speed at the receiving station matches the conveying speed of the feeding conveyor. However, in actual production, the conveying speed of the feeding conveyor is often much greater than the material handling speed at the receiving station. To avoid material accumulation at the receiving station, the speed of the feeding conveyor must be reduced, resulting in low utilization efficiency of the feeding conveyor and hindering the improvement of overall work efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a single-sided lifting belt conveyor and conveying system, enabling one feeding conveyor to supply materials to two receiving conveyors, thus significantly improving production efficiency.

[0005] This utility model is achieved through the following technical solution: a single-sided lifting belt conveyor is provided, including a frame and a conveyor belt rotatably mounted on the frame, and a base frame. The frame is hinged to the base frame via a horizontal shaft, and a drive mechanism is installed on the base frame to drive the frame to swing up and down around the axis of the horizontal shaft.

[0006] In this solution, a single-sided lifting belt conveyor is positioned between the feeding conveyor and the receiving conveyor. The feed end of the conveyor belt is matched with the discharge end of the feeding conveyor. When the drive mechanism rotates the frame until the discharge end of the conveyor belt is in the upper position, it is matched with the feed end of the upper receiving conveyor. The bagged material conveyed by the feeding conveyor is then transported to the upper receiving conveyor via the single-sided lifting belt conveyor. When the drive mechanism rotates the frame until the discharge end of the conveyor belt is in the lower position, it is matched with the feed end of the lower receiving conveyor. The bagged material conveyed by the feeding conveyor is then transported to the lower receiving conveyor via the single-sided lifting belt conveyor. This achieves the diversion of the material conveyed by the feeding conveyor and simultaneously feeds two receiving conveyors, meeting the material needs of at least two workstations.

[0007] As an optimization, the drive mechanism includes a drive motor, a reducer connected to the output shaft of the drive motor, and a support frame hinged at one end to the frame. A crank arm is hinged to the other end of the support frame, and the end of the crank arm away from the support frame is sleeved and fixed to the output shaft of the reducer. This optimized drive mechanism uses a drive motor as the power source. Through the force transmission of the reducer, the crank arm rotates. When the crank arm rotates, the force transmission of the support frame causes the frame to swing up and down, achieving single-sided lifting of the belt conveyor and meeting the material conveying needs of at least two receiving conveyors with different heights.

[0008] As an optimization, the reducer has output shafts on opposite sides, and the two output shafts are coaxial. Crank arms are fixed to both output shafts. The support frame includes two parallel support rods connected as one unit by a crossbar, and a lower support shaft fixed to the lower ends of the two support rods. The lower support shaft is parallel to the output shaft of the reducer, and both crank arms are sleeved on the lower support shaft. This optimized design, by setting two crank arms and two support rods, improves the stability of the frame during vertical swinging and also enhances the stability of supporting the single-sided lifting belt conveyor.

[0009] As an optimization, the support frame further includes an upper support shaft fixed to the upper ends of the two support rods, with both ends of the upper support shaft rotatably connected to the frame via bearings with mounting seats. This optimized solution, by setting the upper support shaft, increases the distance between the points of action on the frame, further improving the stability of the single-sided lifting belt conveyor.

[0010] As an optimization, the base frame includes a rear side frame and a stabilizing frame located in front of and fixed to the rear side frame. The rear end of the frame is hinged to the rear side frame, and the frame extends forward above the stabilizing frame. This optimized solution sets the hinge point on the rear side frame and sets the stabilizing frame in front of the rear side frame and below the frame, ensuring the stability of the single-sided lifting structure.

[0011] As an optimization, the base frame also includes an inclined reinforcing beam, the upper end of which is fixedly connected to the rear frame, and the lower end of which is fixedly connected to the stabilizing frame. This optimization scheme improves the connection strength between the rear frame and the stabilizing frame by adding a reinforcing beam, thereby improving the structural strength of the entire base frame and further enhancing the stability of the single-sided lifting structure.

[0012] This solution also provides a conveying system including the aforementioned single-sided lifting belt conveyor. The conveying system further includes a first conveyor located on the feeding side of the single-sided lifting belt conveyor, and a second and third conveyor located on the discharging side of the single-sided lifting belt conveyor. The second conveyor is positioned above the third conveyor. The feeding end of the single-sided lifting belt conveyor is adapted to the discharging end of the first conveyor. When the discharging end of the single-sided lifting belt conveyor is at a high position, it is adapted to the feeding end of the second conveyor; when the discharging end of the single-sided lifting belt conveyor is at a low position, it is adapted to the feeding end of the third conveyor. In this conveying system, the up-and-down swing of the single-sided lifting belt conveyor allows the material conveyed by the first conveyor to be alternately conveyed to the second and third conveyors after passing through the single-sided lifting belt conveyor, simultaneously satisfying the material requirements of the second and third conveyors.

[0013] The beneficial effects of this utility model are as follows: by setting the belt conveyor to a single-sided lifting structure, and by utilizing the up-and-down swing of the frame, the discharge end of the conveyor belt can correspond to receiving conveyors of different receiving heights, thereby realizing alternating feeding to receiving conveyors of different receiving heights, improving the utilization efficiency of the feeding conveyor, and thus improving the overall operating efficiency.

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0022] Example 1

[0023] like Figures 1-4 The single-sided lifting belt conveyor shown includes a frame 2 and a conveyor belt 1 rotatably mounted on the frame 2. A roller adapted to the conveyor belt is rotatably mounted on the frame, and an electric motor 9 is installed on the frame to drive the conveyor belt. The electric motor drives the roller to rotate, thereby driving the conveyor belt to rotate.

[0024] The single-sided lifting belt conveyor of this embodiment also includes a base frame located below the frame 2. The rear end of the frame is hinged to the base frame via a horizontal shaft 3. The horizontal shaft is coaxial with the rear end roller. A drive mechanism is installed on the base frame to drive the frame to swing up and down around the axis of the horizontal shaft 3. When the drive mechanism drives the frame to swing up and down, the rear end height of the conveyor belt 1 remains unchanged, while the front end of the conveyor belt moves up and down to meet the requirements of receiving conveyors with different feeding heights.

[0025] Specifically, the drive mechanism includes a drive motor 4, a reducer 11 that is drively connected to the output shaft of the drive motor, and a support frame 8 that is hinged at one end to the frame. A crank arm 10 is hinged to the other end of the support frame, and the end of the crank arm 10 away from the support frame is sleeved and fixed to the output shaft of the reducer. The drive mechanism is located below the frame, and the bottom surface of the frame is hinged to the support rod.

[0026] To improve stability, the reducer in this embodiment adopts a dual-output-shaft structure. Output shafts are provided on opposite sides of the reducer, and the two output shafts are coaxial. The crank arms 10 are fixed to both output shafts. Dual-output-shaft reducers are existing technology and can be implemented using bevel gear transmission; their internal structure will not be described in detail here.

[0027] The support frame 8 includes two parallel support rods 82 that are fixed together by a crossbar 84, and a lower support shaft 83 fixed to the lower end of the two support rods. The two ends of the crossbar are welded to the two support rods respectively, and the lower support shaft is also welded to the support rods. The lower support shaft 83 is parallel to the output shaft of the reducer. Both of the crank arms 10 are sleeved on the lower support shaft, and the crank arms and the support shaft can rotate relative to each other.

[0028] The support frame also includes an upper support shaft 81 fixed to the upper ends of the two support rods. The support rods are welded to the upper support shaft, and both ends of the upper support shaft are rotatably connected to the frame 2 via seated bearings 12. The seated bearings are fixed to the bottom surface of the frame, and the two seated bearings are located on both sides of the support frame. The upper support shaft passes through the inner hole of the seated bearing.

[0029] The base frame includes a rear side frame 5 and a stabilizing frame 7 located in front of and fixedly connected to the rear side frame 5. The rear end of the frame is hinged to the rear side frame, and the frame extends forward above the stabilizing frame. The base frame also includes an inclined reinforcing beam 6, the upper end of which is fixedly connected to the rear side frame 5, and the lower end of which is fixedly connected to the stabilizing frame 7. In this embodiment, the reinforcing beam is welded to both the rear side frame and the stabilizing frame, and the stabilizing frame is welded to the rear side frame. Four rectangularly arranged support legs are fixedly mounted at the bottom of the base frame. Flange plates are fixedly connected to the lower ends of the support legs, and bolt holes are provided on the flange plates for inserting anchor bolts to facilitate the fixing of the base frame.

[0030] In this embodiment, the single-sided lifting belt conveyor is located between the feeding conveyor and the receiving conveyor. The receiving conveyor consists of two units arranged vertically. The feed end of the single-sided lifting belt conveyor is matched with the discharge end of the feeding conveyor. When the drive mechanism rotates the frame of the single-sided lifting belt conveyor to the upper position (where the discharge end is aligned with the upper receiving conveyor), the bagged material fed by the feeding conveyor is transported to the upper receiving conveyor via the single-sided lifting belt conveyor. When the drive mechanism rotates the frame to the lower position (where the discharge end is aligned with the lower receiving conveyor), the bagged material fed by the feeding conveyor is transported to the lower receiving conveyor via the single-sided lifting belt conveyor. This achieves the diversion of materials fed by the feeding conveyor and simultaneously feeds two receiving conveyors, meeting the material needs of at least two workstations.

[0031] Example 2

[0032] This embodiment provides a conveying system, which includes the single-sided lifting belt conveyor described in Embodiment 1, a first conveyor 13 located on the feeding side of the single-sided lifting belt conveyor, and a second conveyor 14 and a third conveyor 15 located on the discharging side of the single-sided lifting belt conveyor. The first, second, and third conveyors are all belt conveyors. The second conveyor 14 is located above the third conveyor 15, and the length of the second conveyor 14 is greater than the length of the third conveyor 15. The discharging ends of the second conveyor 14 and the third conveyor 15 correspond to different work positions. The feeding end of the single-sided lifting belt conveyor is adapted to the discharging end of the first conveyor. When the discharging end of the single-sided lifting belt conveyor is at a high position, it is adapted to the feeding end of the second conveyor. When the discharging end of the single-sided lifting belt conveyor is at a low position, it is adapted to the feeding end of the third conveyor.

[0033] In use, the frame of the single-sided lifting belt conveyor swings up and down, so that the material on the first conveyor is alternately transported to the second and third conveyors. This not only meets the material requirements of the corresponding workstations at the discharge end of the second and third conveyors, but also greatly improves the working efficiency of the first conveyor.
