Description

Technical Field

[0001] This application relates to the technical field of conveyors, and in particular to a direct-drive belt conveyor. Background Technology

[0002] Belt conveyors, also known as rubber belt conveyors, are commonly referred to as conveying equipment. They are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food for the assembly, testing, debugging, packaging, and transportation of goods. Conveying equipment includes belt conveyors, also called belt conveyors or rubber belt conveyors, which are indispensable and economical logistics conveying equipment for forming rhythmic assembly lines. Belt conveyors can be classified according to their conveying capacity into heavy-duty belt conveyors, such as mining belt conveyors, and light-duty belt conveyors, such as those used in the electronics, plastics, food, light industry, chemical, and pharmaceutical industries. Belt conveyors have the advantages of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automated operation. They use the continuous or intermittent movement of the conveyor belt to transport items weighing less than 100KG or powdery or granular materials. They operate at high speed, smoothly, with low noise, and can convey items uphill and downhill.

[0003] A search revealed Chinese Patent Publication No. CN216425689U, which discloses a permanent magnet direct-drive belt conveyor. The conveyor includes a first silencing plate and a second silencing plate fixedly installed on the inner wall of the first silencing plate. A silencing box is movably disposed to the left of the first silencing plate, and a permanent magnet coupling direct-drive system is fixedly installed on the inner wall of the silencing box. This conveyor utilizes the first and second silencing plates to eliminate noise generated by the conveyor belt during operation. The silencing box and second silencing pipe eliminate noise generated by the permanent magnet coupling direct-drive system during operation. The second and third troughs further enhance the noise reduction effect, and the first silencing pipe further eliminates noise generated by the conveyor belt during operation.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following defects: conveyor belts are prone to deformation and loosening after prolonged use, thereby affecting the transmission effect. The existing technology lacks an adjustment mechanism, making it inconvenient to adjust the tension of the conveyor belt. In order to solve the problem of the lack of an adjustment mechanism in the existing technology, this application uses a movable roller to adjust the conveyor belt, so that the conveyor belt is kept in a taut state, thereby avoiding the conveyor belt loosening from affecting the transmission and achieving the effect of improving the service life of the conveyor belt.

[0028] This application discloses a direct-drive belt conveyor. For example... Figure 1 , 2As shown in Figures 3 and 4, a direct-drive belt conveyor includes an installation trough 1. A motor is fixedly mounted on the outer surface of the installation trough 1. A conveyor belt 2 is arranged inside the installation trough 1. A base plate 12 is arranged below the conveyor belt 2. A motor is mounted on the lower surface of the base plate 12. A drive roller 4 and a driven roller 5 are rotatably connected inside the installation trough 1. A hopper is installed on the side of the installation trough 1 near the driven roller 5. One end of the drive roller 4 is fixedly connected to the output end of the corresponding motor. Both the drive roller 4 and the driven roller 5 are driven by the conveyor belt 2. A positioning frame 6 is arranged below the conveyor belt 2. The positioning frame 6 is fixedly connected to the installation trough 1. A movable clamp 7 is slidably connected inside the positioning frame 6. A movable roller 3 is arranged inside the conveyor belt 2. Both ends of 3 are rotatably connected to the interior of the movable clamp 7. The outer surface of the positioning frame 6 is provided with a positioning groove 8. Two positioning blocks 9 are slidably connected inside the positioning groove 8. The positioning blocks 9 are symmetrically installed. A positioning rod 10 is rotatably connected inside the positioning groove 8. The outer surface of the positioning rod 10 is provided with a bidirectional thread. The positioning rod 10 is threadedly connected to the interior of the positioning block 9. A handle is fixedly installed at one end of the positioning rod 10. Each positioning block 9 is rotatably connected to two support bars 11. The other end of each support bar 11 is rotatably connected to the movable clamp 7. When the positioning rod 10 is rotated, the positioning rod 10 drives the two positioning blocks 9 to slide. The positioning blocks 9 drive the movable clamp 7 and the movable roller 3 to move downward through the support bars 11, thereby making the conveyor belt taut.

[0029] Please see Figure 1 , 2 5. A support column 13 is provided on both sides of the driven roller 5. The support columns 13 are symmetrically installed. The bottom end of each support column 13 is fixedly connected to the upper surface of the base plate 12. A first roller 14 is provided inside each support column 13. Each roller 14 is rotatably connected to the outer surface of the mounting groove 1.

[0030] Please see Figure 1 , 2 5. Two support plates 15 are fixedly connected to the upper surface of the base plate 12. The support plates 15 are symmetrically installed. Each support plate 15 has a second roller 16 inside. Each second roller 16 is rotatably connected to the outer surface of the mounting groove 1.

[0031] Please see Figure 1 , 5 A slide bar 17 is slidably connected to the upper surface of the base plate 12. A support rod 18 is rotatably connected to both ends of the slide bar 17. The other end of each support rod 18 is rotatably connected to the outer surface of the mounting groove 1. When the slide bar 17 slides, the slide bar 17 drives the first roller 14 to move upward inside the support column 13 through the support rod 18 and the mounting groove 1.

[0032] Please see Figure 5 , 6A drive bar 19 is slidably connected to the lower surface of the base plate 12. The drive bar 19 is fixedly connected to the slide bar 12. A drive rod 20 is threadedly connected to the inside of the drive bar 19. One end of the drive rod 20 is fixedly connected to the output end of the corresponding motor.

[0033] Please see Figure 5 , 6 Two limiting strips 21 are fixedly connected to the lower surface of the base plate 12. Each limiting strip 21 is rotatably connected to one end of the drive rod 20. Two limiting grooves 22 are opened on the lower surface of the base plate 12. The slide bar 17 and the drive rod 19 are fixed together through the limiting grooves 22. The limiting grooves 22 limit the sliding of the slide bar 17 and the drive rod 19.

[0034] Please see Figure 2 , 3 Both sides of the movable roller 3 are provided with support rollers 23 arranged at equal distances. Both ends of each support roller 23 are rotatably connected to the inside of the mounting groove 1. Each support roller 23 is located inside the conveyor belt 2. The outer surface of the support roller 23 is in contact with the inside of the conveyor belt 2. The support roller 23 plays an auxiliary supporting role for the conveyor belt 12.

[0035] The implementation principle of a direct-drive belt conveyor according to an embodiment of this application is as follows: the motor drives the drive rod 20 to rotate, the drive rod 20 drives the drive bar 19 and the slide bar 17 to slide, the slide bar 17 drives the first roller 14 to move upward inside the support column 13 through the support rod 18 and the mounting groove 1, and at the same time the mounting groove 1 drives the second roller 16 to slide inside the support plate 15, thereby realizing the adjustment of the conveying height. When the conveyor belt 2 becomes loose, the positioning rod 10 is rotated, the positioning rod 10 drives the slider 9 to slide, and the slider 9 drives the movable clamp 7 and the movable roller 3 to move downward through the support bar 11, so that the conveyor belt 2 remains taut.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
