Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a belt conveyor line. Background Technology

[0002] A ton bag is a medium-sized bulk container, a type of unitized container. Equipped with a crane or forklift, it enables unitized transportation. In a factory, conveyor lines transport the assembled ton bags. Existing technology includes a patent (CN 212374288 U) that discloses a belt conveyor device, comprising: a support frame; an adjusting device mounted on the support frame; and a belt conveyor unit mounted on the adjusting device. This invention uses a servo motor for transmission, resulting in high transmission efficiency, precise conveying control, and a compact structure. However, this device lacks a belt tension detection element, and belt slack requires visual inspection by workers, followed by tension adjustment using the corresponding tension control element. This needs improvement. Therefore, we propose a belt conveyor line. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a belt conveyor line. This device can automatically detect the belt tension of the pulley through detection elements and transmission elements. If the belt is loose, the device can automatically adjust the belt tension without the need for personnel intervention. It is easy to use and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a belt conveyor line, including a support frame, with pulleys installed at both ends of the support frame, the pulleys being connected by belt drive, and also including a tensioning mechanism;

[0005] The tensioning mechanism includes an extension seat, a guide seat, a linkage seat, a clearance groove, an adjustment component, and a detection component. The extension seats are respectively located at the front and rear ends of the left side of the support frame. Guide seats are provided on both the upper and lower walls of the extension seats. A linkage seat is slidably connected between two vertically connected guide seats. The front and rear ends of the left pulley are rotatably connected to the adjacent linkage seat through bearing one. A clearance groove is provided in the middle of the extension seat. The front and rear ends of the left pulley pass through the adjacent clearance groove. An adjustment component is provided between the front extension seat and the front linkage seat. A detection component is provided between the left pulley and the support frame. The front and rear ends of the right pulley are rotatably connected to the inner wall of the support frame through bearing two. This device can automatically detect the belt tension of the pulley through the detection element and the transmission element. If the belt is loose, the device can automatically adjust the belt tension without the need for operator intervention, making it convenient to use.

[0006] Furthermore, it also includes a microcontroller, which is located outside the support frame. The input terminal of the microcontroller is electrically connected to an external power supply, which facilitates the control of electrical components inside the device.

[0007] Furthermore, the adjustment assembly includes a threaded cylinder, a stud, a bellows, and a low-speed motor. The threaded cylinder is located on the left side of the front connecting seat. The left wall of the front extension seat is rotatably connected to the stud via a bearing. The right end of the stud is threadedly connected to the threaded cylinder. The left side of the front extension seat is equipped with a low-speed motor. The input end of the low-speed motor is electrically connected to the output end of the microcontroller. The output shaft of the low-speed motor is fixedly connected to the left end of the stud. A bellows is provided between the left side of the threaded cylinder and the front extension seat. The bellows is movably sleeved on the outer end of the stud to electrically adjust the belt tension in the belt conveyor line.

[0008] Furthermore, the detection component includes an annular groove, an annular seat, a pressure sensor, an arc-shaped pressure plate, and a telescopic rod. The annular grooves are longitudinally and evenly distributed on the outer side of the left-side pulley. The annular grooves are rotatably connected to the annular seat through sealed bearings. A pressure sensor is provided at the left end of the outer side of each annular seat. The detection end of each pressure sensor is provided with an arc-shaped pressure plate. The pressure sensor is bidirectionally electrically connected to the microcontroller. A telescopic rod is provided vertically and symmetrically distributed between the annular seat and the adjacent arc-shaped pressure plate. The horizontal rightward tension pressure applied by the belt to the arc-shaped pressure plate in the belt conveyor line is measured and uploaded.

[0009] Furthermore, the detection component also includes ball bearings, which are uniformly rotated and connected to the semicircular grooves opened on the outer arc surface of the arc-shaped pressure plate, thereby reducing the contact friction between the inner arc-shaped pressure plate and the belt in the belt conveyor line.

[0010] Furthermore, the detection assembly also includes a fixed rod and a second telescopic rod. The fixed rod is disposed between the front and rear walls of the support frame, and the annular seat and the fixed rod are fixedly connected by the second telescopic rod to limit the rotation of the annular seat in the belt conveyor line.

[0011] Furthermore, the front and rear walls of the support frame are rotatably connected by bearings with evenly distributed support rollers to provide auxiliary support for the belt operation of the belt conveyor line.

[0012] Furthermore, a servo motor is provided at the rear right end of the support frame. The input end of the servo motor is electrically connected to the output end of the microcontroller, and the output shaft of the servo motor is fixedly connected to the middle of the rear end of the right-side pulley, providing power for the belt operation of the belt conveyor line.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This belt conveyor line has the following advantages:

[0014] When using a belt conveyor, the device uses a pressure detection element to measure the horizontal rightward tension pressure applied to the measuring point at the initial stage of the belt and uploads it as a comparison value. When the tension pressure value uploaded by the pressure detection element is less than the comparison value during subsequent use, the belt becomes loose. The belt tension can then be automatically adjusted by the adjustment component without the need for operator intervention, making it convenient to use. Attached Figure Description

The extension seats 51 are respectively located at the front and rear ends of the left side of the support frame 1. The upper and lower walls of the extension seats 51 are provided with guide seats 52. A linkage seat 53 is slidably connected between two vertically connected guide seats 52. The front and rear ends of the left pulley 3 are rotatably connected to the adjacent linkage seat 53 through a bearing. A clearance groove 54 is opened in the middle of the extension seats 51. The front and rear ends of the left pulley 3 pass through the adjacent clearance groove 54. An adjustment component 55 is provided between the front extension seat 51 and the front linkage seat 53. A detection component 56 is provided between the left pulley 3 and the support frame 1. The front of the right pulley 3... Both ends are rotatably connected to the inner wall of the support frame 1 via bearing 2. The adjustment component 55 includes a threaded cylinder 551, a stud 552, a bellows 553, and a low-speed motor 554. The threaded cylinder 551 is located on the left side of the connecting seat 53 on the front side. The left wall of the extension seat 51 on the front side is rotatably connected to the stud 552 via bearing 3. The right end of the stud 552 is threadedly connected to the threaded cylinder 551. The left side of the extension seat 51 on the front side is provided with the low-speed motor 554. The input end of the low-speed motor 554 is electrically connected to the output end of the microcontroller 2. The output shaft of the low-speed motor 554 is fixedly connected to the left end of the stud 552. A bellows 553 is provided between the left side of the threaded cylinder 551 and the extension seat 51 on the front side. The bellows 553 is movably sleeved on the outer end of the stud 552. Detection component 5 The detection assembly 56 includes an annular groove 561, an annular seat 562, a pressure sensor 563, an arc-shaped pressure plate 564, and a telescopic rod 566. The annular grooves 561 are evenly spaced longitudinally on the outer side of the left-side pulley 3. The annular seat 562 is rotatably connected to the inside of each annular groove 561 through a sealed bearing. The pressure sensor 563 is provided at the left end of the outer side of each annular seat 562. The detection end of each pressure sensor 563 is provided with an arc-shaped pressure plate 564. The pressure sensor 563 is bidirectionally electrically connected to the microcontroller 2. Vertically symmetrically distributed telescopic rods 566 are provided between the annular seat 562 and the adjacent arc-shaped pressure plate 564. The detection assembly 56 also includes ball bearings 565, which are evenly rotatably connected to the semicircular grooves opened on the outer arc surface of the arc-shaped pressure plate 564. The detection component 56 also includes a fixed rod 567 and a telescopic rod 568. The fixed rod 567 is located between the front and rear walls of the support frame 1. The annular seat 562 and the fixed rod 567 are both fixedly connected by the telescopic rod 568. In the initial stage of use of the belt conveyor line, the microcontroller 2 starts the pressure sensor 563, and the pressure sensor 563 runs. The pressure sensor 563 is a sensor made using the piezoresistive effect of single-crystal silicon material and integrated circuit technology. Initially, the belt 4 is in a taut state. The horizontal rightward tension applied by the belt 4 to the arc-shaped pressure plate 564 is applied to the single-crystal silicon material of the pressure sensor 563 (the outer arc surface of the arc-shaped pressure plate 564 protrudes to the outer arc surface of the left pulley 3). The resistivity of the single-crystal silicon material changes after being compressed.The measuring circuit outputs an electrical signal proportional to the force change, thus measuring the initial tension pressure exerted by the belt 4 on the arc-shaped pressure plate 564. The result is transmitted to the microcontroller 2 as an electrical signal. Multiple pressure sensors 563 are used; the microcontroller 2 aggregates the data from these sensors and takes the average value. This value is then recorded as the initial tension value. The telescopic rod 566 horizontally guides the tension pressure from the belt 4 on the arc-shaped pressure plate 564, preventing the belt 4 from applying pressure to the detection end of the pressure sensor 563 through the arc-shaped pressure plate 564 during subsequent movement. In addition to applying forces in other directions besides the horizontal direction, the contact area between the arc-shaped pressure plate 564 and the belt 4 is reduced by the ball bearings 565, thereby avoiding excessive contact friction between the belt 4 and the arc-shaped pressure plate 564 during later operation. During the use of the belt conveyor line, when the tension pressure applied by the belt 4 to the arc-shaped pressure plate 564 by the pressure sensor 563 is less than the initial tension value, the belt 4 becomes slack. Subsequently, the microcontroller 2 starts the low-speed motor 554. The low-speed motor 554 combines a common asynchronous motor with a gearbox and other reduction devices, reducing the speed and increasing speed through the gear reduction ratio. The output shaft of the high-torque, low-speed motor 554 drives the stud 552 to rotate. During the rotation of the stud 552, the threaded connection causes the threaded cylinder 551 to move to the left. The threaded cylinder 551 drives the connecting seat 53 to slide to the left along the corresponding guide seat 52. The guide seat 52 drives the left pulley 3 to move synchronously. By increasing the center distance between the two pulleys 3, the belt 4 is tensioned, thereby realizing the self-adjusting operation of the belt 4 tension. During this process, components such as the annular seat 562 move to the left synchronously with the left pulley 3, and the telescopic end of the telescopic rod 568 adapts to the movement of the annular seat 562. The telescopic mechanism, via telescopic rod 568, prevents the annular seat 562 from rotating with the left-side pulley 3. A bellows 553 encloses and lubricates the exposed end of the stud 552, providing a seal. The bellows 553 is a corrugated structure made of multiple layers of stacked metal sheets; its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance. This device, through detection and transmission elements, can automatically detect the tension of the belt 4 on the pulley 3. If the belt 4 becomes loose, the device can automatically adjust the belt tension without operator intervention, making it convenient to use.

[0023] The working principle of the belt conveyor provided by this utility model is as follows: In the initial stage of use, the microcontroller 2 starts the pressure sensor 563, and the pressure sensor 563 operates. The pressure sensor 563 is a sensor made using the piezoresistive effect of single-crystal silicon material and integrated circuit technology. Initially, the belt 4 is in a tensioned state. The horizontal rightward tension applied by the belt 4 to the arc-shaped pressure plate 564 is applied to the single-crystal silicon material of the pressure sensor 563 (the outer arc surface of the arc-shaped pressure plate 564 protrudes to the outer arc surface of the left pulley 3). After being compressed, the resistivity of the single-crystal silicon material changes. Through the measuring circuit, an electrical signal output proportional to the force change can be obtained, thereby measuring the tension pressure applied by the belt 4 to the arc-shaped pressure plate 564 at the initial stage of the device, and... The result is transmitted to the microcontroller 2 as an electrical signal. There are multiple sets of pressure sensors 563. The microcontroller 2 summarizes the data uploaded by multiple sets of pressure sensors 563 and takes the average value. Then, the microcontroller 2 records this value as the initial tension value. The tension pressure of the belt 4 on the arc-shaped pressure plate 564 is horizontally guided by the telescopic rod 566, thereby preventing the belt 4 from applying forces other than the horizontal direction to the detection end of the pressure sensor 563 through the arc-shaped pressure plate 564 during subsequent movement. The ball bearings 565 reduce the contact area between the arc-shaped pressure plate 564 and the belt 4, thereby avoiding large contact friction between the belt 4 and the arc-shaped pressure plate 564 during later operation. Then, the microcontroller 2 starts the servo motor 7 so that its output shaft drives the pulley 3 on the right side to rotate. The pulley 3 on the right side drives the belt 4 to rotate through the contact friction between the pulley and the belt 4. During the rotation of the belt 4, the contact friction between its upper surface and the bottom of the item conveys the item. The upper outer end of the support roller 6 contacts the top of the belt 4, providing auxiliary support for the conveying of items on the belt 4. During the use of the belt conveyor line, when the tension pressure applied by the belt 4 to the arc-shaped pressure plate 564 by the pressure sensor 563 is less than the initial tension value, the belt 4 becomes slack. Subsequently, the microcontroller 2 starts the low-speed motor 554. The low-speed motor 554 combines a common asynchronous motor with a gearbox and other reduction devices. Through the gear reduction ratio, the speed is reduced and the torque is increased. The output of the low-speed motor 554... The output shaft drives the stud 552 to rotate. During the rotation of the stud 552, the threaded connection causes the threaded cylinder 551 to move to the left. The threaded cylinder 551 drives the connecting seat 53 to slide to the left along the corresponding guide seat 52. The guide seat 52 drives the left pulley 3 to move synchronously. By increasing the center distance between the two pulleys 3, the belt 4 is tensioned, thereby realizing the self-adjustment of the belt 4 tension. During this process, components such as the annular seat 562 move to the left synchronously with the left pulley 3. The telescopic end of the telescopic rod 568 extends and retracts adaptively with the movement of the annular seat 562. The telescopic rod 568 prevents the annular seat 562 from rotating with the left pulley 3. The exposed end of the stud 552 is wrapped, lubricated and sealed by the bellows 553.The 553 bellows is a corrugated structure made of multiple layers of laminated metal sheets. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance.

The microcontroller 2 controls the operation of the low-speed motor 554, the pressure sensor 563, and the servo motor 7 using methods commonly used in the prior art.
