Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyors for automatically maintaining the position of the conveyor belt, specifically a safety conveyor belt alignment device. Background Technology
[0002] Belt conveyors are a common conveying method. A belt is wound around conveyor rollers, and the rotation of the rollers drives the belt to move, thus transporting the material on the belt to various workstations. During the conveying process, the belt wound around the conveyor rollers can sometimes deviate from its designated path, causing the belt's central axis to deviate from the conveying direction. Currently, belt deviation is usually adjusted manually, and this adjustment must be performed while the machine is running. This is time-consuming, labor-intensive, and poses safety hazards. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology and provide a convenient, safe and reliable conveying equipment, this utility model discloses a safety conveyor belt alignment device.
[0004] This utility model achieves its invention objective through the following technical solution:
[0005] A safety-type conveyor belt alignment device includes idlers, a frame, and a belt. There are at least two sets of idlers, each set consisting of three idlers. The three idlers in each set are arranged sequentially end-to-end and rotatably mounted on the frame. The outer ends of the idlers at both ends are inclined upwards, forming an upward-opening trough shape in each set. The idlers in each set are arranged parallel to each other. The belt is wound in a loop around each set of idlers, and its shape matches that of each set of idlers.
[0006] Its features include: support rods, support frames, bases, drive shafts, supports, rotating shafts, couplings, turntables, transmission mechanisms, support seats, and base plates.
[0007] The frame consists of three frame plates, which are joined together with their sides to form an upward-opening groove.
[0008] The idler rollers are set in the slots formed by the frame plates. In each set of idler rollers: the outer end faces of the idler rollers on both sides are rotatably set on a frame plate on both sides through support rods. A support frame is embedded between each of the two adjacent idler rollers. The inner end faces of the idler rollers on both sides are rotatably set on a frame plate in the middle through one side of the support frame. The two end faces of the idler roller in the middle are rotatably set on the frame plate in the middle through the other side of the support frame.
[0009] The frame is mounted on a base, with a baffle at each end of the base. A drive shaft is rotatably mounted on each side of the base. A support is located in the middle of the base, with a rotating shaft rotatably mounted on each side of the support. The inner end of each drive shaft passes through the baffle on the same side and is connected to the outer end of the rotating shaft on the same side via a coupling. A turntable is rotatably mounted on the top of the support. The central axis of the turntable is perpendicular to the central axes of the two rotating shafts. The inner ends of a rotating shaft are connected to the bottom of the turntable on both sides via a transmission mechanism. The transmission mechanism converts the rotation of the rotating shaft into the rotation of the turntable. Two support seats are also provided on the base, each of which is located on one side of a drive shaft.
[0010] The middle of the bottom surface of the frame plate is fixed to the turntable, and the two sides are movably mounted on a support base via a base plate.
[0011] The safety conveyor belt alignment device is characterized in that it further includes two handwheels and two protective nets, each handwheel being fixed to the outer end face of a drive shaft, and the bottom of each protective net being fixed to the top of a baffle.
[0012] The safety conveyor belt alignment device is characterized in that: a rolling element is rotatably provided on the top of the support base, and the bottom plate is movably provided on the support base through the rolling element.
[0013] The aforementioned safety conveyor belt alignment device is characterized in that: the transmission mechanism is selected from a bevel gear set or a worm gear-worm combination.
[0014] In use, this invention utilizes a rotating idler roller to drive a belt conveyor to transport materials. When belt misalignment occurs, the drive shaft is rotated, which, through a coupling, drives a rotating disc. The transmission mechanism converts the horizontal rotation of the rotating disc into vertical rotation of a turntable, which in turn causes the frame plate to shift, thereby correcting the misaligned belt. Adding a handwheel to the drive shaft facilitates its rotation, and a protective net to the base further enhances safety.
[0015] This utility model uses a drive mechanism and a turntable to shift the frame outside the operating area of the roller (1) to achieve the effect of straightening the belt. The belt does not need to be stopped during the straightening process. It has the following advantages: simple structure, easy to use, good straightening effect, self-locking, safe and reliable, and improved production efficiency. Attached Figure Description

[0021] There are at least two sets of idler rollers 1, each set including three idler rollers 1. The three idler rollers 1 in each set are arranged end to end and are rotatably mounted on the frame 2. The outer ends of the idler rollers 1 at both ends are inclined upward, so that the three idler rollers 1 in each set form an upward-opening groove. The idler rollers 1 in each set are arranged parallel to each other in sequence. The belt 3 is wound in a ring around each set of idler rollers 1 in sequence and matches the shape of each set of idler rollers 1.
[0022] The frame 2 includes three frame plates 21, which are joined together with their sides to form an upward-opening groove.
[0023] The idler roller 1 is set in the groove formed by the frame plate 21. In each set of idler rollers 1: the outer end face of the idler rollers 1 located on both sides is rotatably set on a frame plate 21 located on both sides through the support rod 41. A support frame 42 is embedded between two adjacent idler rollers 1. The inner end face of the idler rollers 1 on both sides is rotatably set on a frame plate 21 located in the middle through one side of the support frame 42. The two end faces of the idler roller 1 located in the middle are rotatably set on the frame plate 21 located in the middle through the other side of the support frame 42.
[0024] The frame 2 is mounted on the base 5. A baffle 51 is provided at each end of the base 5. A drive shaft 61 is rotatably mounted on each side of the base 5. A support 62 is provided in the middle of the base 5. A rotating shaft 63 is rotatably mounted on each side of the support 62. The inner end of each drive shaft 61 passes through the baffle 51 on the same side and is connected to the outer end of the rotating shaft 63 on the same side through a coupling 64. A turntable 65 is rotatably mounted on the top of the support 62. The central axis of the turntable 65 is perpendicular to the central axes of the two rotating shafts 63. The inner ends of the rotating shafts 63 are connected to the bottom sides of the turntable 65 through a transmission mechanism 66. The transmission mechanism 66 converts the rotation of the rotating shafts 63 into the rotation of the turntable 65. Two support seats 67 are also provided on the base 5. Each support seat 67 is located on one side of a drive shaft 61.
[0025] The bottom of the frame plate 21 located in the middle is fixed to the turntable 65, and the two sides are movably mounted on a support base 67 via a base plate 68.
[0026] This embodiment also includes two handwheels 69 and two protective nets 7. Each handwheel 69 is fixed to the outer end face of a drive shaft 61, and the bottom of each protective net 7 is fixed to the top of a baffle 51.
[0027] In this embodiment: the top of the support base 67 is rotatably provided with a rolling element, and the base plate 68 is movably provided on the support base 67 through the rolling element.
[0028] In this embodiment: the transmission mechanism 66 can be a bevel gear set, and the schematic diagram of the structure of the rotating shaft 63 connected to the turntable 65 through the transmission mechanism 66 of the bevel gear set is shown below. Figure 2 As shown; the transmission mechanism 66 can also be a worm gear combination, and the schematic diagram of the structure in which the rotating shaft 63 is connected to the turntable 65 through the worm gear combination transmission mechanism 66 is shown. Figure 3 As shown.
[0029] In this embodiment, the idler roller 1 rotates, driving the belt 3 to move and convey materials. When the belt 3 deviates from its designated path, the drive shaft 61 is rotated. The drive shaft 61 drives the rotating shaft 63 to rotate via the coupling 64. The transmission mechanism 66 converts the rotation of the horizontal rotating shaft 63 into the rotation of the vertical turntable 65. The turntable 65 causes the frame plate 21 to shift, thereby correcting the deviated belt 3. Adding a handwheel 69 to the drive shaft 61 makes it easier to rotate, and adding a protective net 7 to the base 5 further improves safety.
