Description

Technical Field

[0001] This utility model relates to the technical field of large-angle belt press conveyors, and specifically discloses a large-angle belt press conveyor with a belt press structure. Background Technology

[0002] Large-angle belt conveyors are a type of material conveying equipment specifically designed for large inclination angles (typically ≥30°, covering near-vertical conveying scenarios). They constrain the conveyor belt through a belt-pressing structure, and, combined with components such as corrugated skirts and baffles, achieve stable lifting and transport of bulk and granular materials in steep environments. Their core value lies in overcoming the inclination angle limitations of conventional belt conveyors, significantly reducing site space requirements, and efficiently meeting the vertical material transport needs of mining, building materials, and chemical industries, especially suitable for production scenarios with compact site layouts.

[0003] However, existing steep-angle conveyors have significant drawbacks: First, the drive rollers are mostly fixed, and after long-term operation, the conveyor belt gradually loosens due to natural stretching and mechanical wear, leading to a decrease in friction between the drive rollers and the conveyor belt, directly causing slippage and severely compromising conveying stability. Furthermore, they cannot adapt the conveyor belt tension according to material characteristics. For example, when conveying high-density materials, the required friction necessitates a taut conveyor belt, while when conveying low-density materials, the tension needs to be appropriately reduced to minimize belt wear. The fixed structure cannot meet these differentiated needs. Second, although some equipment allows tension adjustment by adjusting the center distance of the drive rollers, this relies on manual operation, requiring machine shutdown and disassembly, a cumbersome process that severely impacts production continuity.

[0004] Therefore, a large-angle belt press conveyor with a belt press structure is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a large-angle belt-pressing conveyor with a belt-pressing structure. The conveyor belt tension can be adjusted to effectively prevent slippage and improve conveying stability. The belt tension can also be adapted to the material characteristics to meet the diverse needs of different working conditions. Furthermore, the adjustment process is convenient and precise, and can be completed without stopping the machine, avoiding any impact on production continuity.

[0006] This utility model is implemented as follows: a large-angle belt press conveyor with a belt press structure includes a base plate, two connecting plates arranged front and rear on the top of the base plate, two drive rollers rotatably connected between the two connecting plates, and a conveyor belt arranged between the two drive rollers.

[0007] A tension adjustment mechanism is provided on the upper side of the base plate. The tension adjustment mechanism includes a U-shaped frame. A traction roller that abuts against the inner wall of the conveyor belt is rotatably connected inside the U-shaped frame. A worm gear electric actuator is installed at the upper end of the base plate. A tension sensor is fixedly connected between the output end of the worm gear electric actuator and the lower end of the U-shaped frame.

[0008] An operation panel and controller are provided on the top of the base plate;

[0009] Each of the two connecting plates is rotatably connected to a pressure roller on one of its opposite sides, and both pressure rollers abut against the outer wall of the conveyor belt.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-5 A large-angle belt press conveyor with a belt press structure includes a base plate 1, two connecting plates 2 arranged front and rear on the top of the base plate 1, two drive rollers 3 rotatably connected between the two connecting plates 2, and a conveyor belt 5 arranged between the two drive rollers 3.

[0028] A tension adjustment mechanism is provided on the upper side of the base plate 1. The tension adjustment mechanism includes a U-shaped frame 9. A traction roller 10 that abuts against the inner wall of the conveyor belt 5 is rotatably connected inside the U-shaped frame 9. A worm gear electric actuator 12 is installed at the upper end of the base plate 1. A tension sensor 11 is fixedly connected between the output end of the worm gear electric actuator 12 and the lower end of the U-shaped frame 9.

[0029] An operation panel 14 and a controller 13 are provided on the top of the base plate 1;

[0030] Two connecting plates 2 are rotatably connected to pressure rollers 8 on opposite sides, and both pressure rollers 8 abut against the outer wall of the conveyor belt 5.

[0031] In this embodiment: During operation, one of the drive rollers 3 rotates clockwise, and the two drive rollers 3 work together to drive the conveyor belt 5 to transport materials. The two pressure rollers 8 are always in contact with the corners of the outer wall of the conveyor belt 5, providing stable pressure to the conveyor belt 5.

[0032] When it is necessary to adjust the tension of the conveyor belt 5, a command is input through the operation panel 14. After receiving the signal, the controller 13 controls the worm gear electric actuator 12 to start. The output end of the worm gear electric actuator 12 drives the U-shaped frame 9 to move through the tension sensor 11, causing the traction roller 10 connected inside the U-shaped frame 9 to change the contact force with the inner wall of the conveyor belt 5, thereby dynamically adjusting the tension of the conveyor belt 5. When the U-shaped frame 9 and the traction roller 10 move downward, the tension of the conveyor belt 5 increases; when the traction roller 10 moves upward, the tension of the conveyor belt 5 decreases. During this process, the tension sensor 11 feeds back the detected tension data to the controller 13 in real time. Since the tension data is positively correlated with the tension of the conveyor belt 5, the controller 13 can accurately determine the current tension state through this data. When the tension reaches the set threshold, the controller 13 controls the worm gear electric actuator 12 to stop moving, ensuring adjustment accuracy. The adjustable conveyor belt tension effectively prevents slippage and improves conveying stability. The tension can also be adapted to the material characteristics to meet the different needs of various working conditions.

[0033] In addition, the entire adjustment process is automated through the operation panel 14 and the controller 13, and the tension status is monitored in real time by the tension sensor 11. It can be completed without stopping the machine, and the adjustment process is convenient and accurate, avoiding any impact on the continuity of production.

[0034] As a technical optimization of this utility model, the outer wall of the conveyor belt 5 is provided with two corrugated skirts 6, which are located on opposite sides of the two pressure rollers 8, and the outer wall of the conveyor belt 5 is provided with multiple baffles 7 located between the two corrugated skirts 6.

[0035] In this embodiment, the two corrugated skirts 6 on the outer wall of the conveyor belt 5 are located on opposite sides of the two pressure rollers 8, which can prevent the material from sliding off from both sides of the conveyor belt 5. The multiple baffles 7 located between the two corrugated skirts 6 can support the material during large-angle conveying, preventing the material from sliding down due to gravity, and jointly improving the stability of material conveying.

[0036] As a technical optimization of this utility model, a drive motor 4 with its output end fixedly connected to one of the transmission rollers 3 is installed on the outer wall of the connecting plate 2 located on the front side.

[0037] In this embodiment: when the drive motor 4 is working, its output end directly drives one of the transmission rollers 3 that is fixedly connected to it to rotate.

[0038] As a technical optimization of this utility model, two guide cylinders 17 are fixedly connected to the upper end of the base plate 1, and guide rods 18 that are fixedly connected to the U-shaped frame 9 are slidably connected inside the two guide cylinders 17.

[0039] In this embodiment: the two guide cylinders 17 at the upper end of the base plate 1 cooperate with the guide rods 18 that are fixedly connected to the U-shaped frame 9. When the worm gear electric actuator 12 drives the U-shaped frame 9 to move, the guide rods 18 slide in the guide cylinders 17 to provide guidance for the movement of the U-shaped frame 9 and ensure that the pull roller 10 stably adjusts the tension of the conveyor belt 5.

[0040] As a technical optimization of this utility model, a plurality of support rollers 16 that abut against the inner wall of the conveyor belt 5 are rotatably connected between the two connecting plates 2, and a positioning roller 19 that abuts against the corner of the bottom side of the inner wall of the conveyor belt 5 is rotatably connected between the two connecting plates 2.

[0041] In this embodiment: multiple support rollers 16 rotatably connected between the two connecting plates 2 abut against the inner wall of the conveyor belt 5, providing support for the conveyor belt 5 and preventing the conveyor belt 5 from sagging due to the weight of the material; the positioning rollers 19 abut against the corner of the bottom side of the inner wall of the conveyor belt 5 can position the corner of the conveyor belt 5, ensuring the stability of the running trajectory of the conveyor belt 5.

[0042] As a technical optimization of this utility model, the lower ends of the two connecting plates 2 are fixedly connected to a first support plate 15 and a second support plate 20, and the two first support plates 15 and the two second support plates 20 are fixedly connected to the base plate 1.

[0043] In this embodiment: the first support plate 15 and the second support plate 20 at the lower end of the two connecting plates 2 are both fixedly connected to the base plate 1, thereby stably connecting the connecting plates 2 and the base plate 1.

[0044] As a technical optimization of this utility model, a vertical plate is fixedly connected to the upper end of the base plate 1, and the operation panel 14 and the controller 13 are installed on the outer wall of the vertical plate.

[0045] In this embodiment, the vertical plate fixedly connected to the upper end of the base plate 1 facilitates the fixed installation of the operation panel 14 and the controller 13.

[0046] The working principle and usage process of this utility model are as follows: During operation, a command is first input through the operation panel 14. After receiving the signal, the controller 13 controls the drive motor 4 to start. The drive motor 4 drives one of the transmission rollers 3 to rotate clockwise. Under the synergistic action of the two transmission rollers 3, the conveyor belt 5 is driven to run to achieve material conveying. The two pressure rollers 8 are always in contact with the corner of the outer wall of the conveyor belt 5, forming a stable pressure on the conveyor belt 5. The two corrugated skirts 6 on the outer wall of the conveyor belt 5, together with multiple baffles 7 located between the two corrugated skirts 6, can effectively restrain the material and prevent the material from slipping during large-angle conveying.

[0047] When it is necessary to adjust the tension of the conveyor belt 5, a command is input through the operation panel 14. After receiving the signal, the controller 13 controls the worm gear electric actuator 12 to start. The output end of the worm gear electric actuator 12 drives the U-shaped frame 9 to move through the tension sensor 11, causing the traction roller 10 connected inside the U-shaped frame 9 to change the contact force with the inner wall of the conveyor belt 5, thereby dynamically adjusting the tension of the conveyor belt 5. When the U-shaped frame 9 and the traction roller 10 move downward, the tension of the conveyor belt 5 increases; when the traction roller 10 moves upward, the tension of the conveyor belt 5 decreases. During this process, the tension sensor 11 feeds back the detected tension data to the controller 13 in real time. Since the tension data is positively correlated with the tension of the conveyor belt 5, the controller 13 can accurately determine the current tension state through this data. When the tension reaches the set threshold, the controller 13 controls the worm gear electric actuator 12 to stop moving, ensuring adjustment accuracy. The adjustable conveyor belt tension effectively prevents slippage and improves conveying stability. The tension can also be adapted to the material characteristics to meet the different needs of various working conditions.

[0048] In addition, the entire adjustment process is automated through the operation panel 14 and the controller 13, and the tension status is monitored in real time by the tension sensor 11. It can be completed without stopping the machine, and the adjustment process is convenient and accurate, avoiding any impact on the continuity of production.
