Description

Technical Field

[0001] This utility model relates to the field of automation control technology, and in particular to an intelligent control device for belt conveyor tension. Background Technology

[0002] A belt conveyor is a continuous conveying device that uses a closed belt loop as a traction component. A drive device drives the belt to circulate along a fixed path to realize the conveying and handling of materials. It is widely used in many industrial fields such as mining, metallurgy, chemical industry, and logistics.

[0003] Traditional belt conveyor tensioning systems provide the necessary tension by installing fixed tensioning pulleys. However, due to the lack of adjustment functions, they cannot adapt to tension changes caused by various factors, resulting in the belt conveyor failing to maintain optimal operating conditions. Although existing technologies employ manual adjustment, this method is both time-consuming and labor-intensive, and it is difficult to achieve precise control. Therefore, improvements are needed. Utility Model Content

[0004] One objective of this invention is to provide an intelligent control device for belt conveyor tension. This invention addresses the problem mentioned in the background that traditional belt conveyor tensioning systems provide the necessary tension by installing fixed tensioning pulleys, but due to the lack of adjustment function, they cannot adapt to tension changes caused by various factors, resulting in the belt conveyor failing to maintain optimal operating conditions. Although existing technologies use manual adjustment, this method is time-consuming, labor-intensive, and difficult to achieve precise control.

[0005] A belt conveyor tension intelligent control device according to an embodiment of the present invention includes:

[0006] The tensioning mechanism includes a housing, inside which a rotating wheel is rotatably mounted. The outer side of the rotating wheel is circular and has toothed grooves. Inside the housing, a first driving mechanism for driving the rotating wheel to rotate is installed. Inside the housing, a second rotating shaft is rotatably mounted. A sleeve is fixedly mounted on the outer side of the second rotating shaft. A buffer assembly is installed between the sleeve and the rotating wheel. A support arm is fixedly mounted on one end of the second rotating shaft, and a tensioning wheel is rotatably mounted on one end of the support arm.

[0007] A lifting mechanism is installed at the position for controlling the tension of the belt conveyor. The lifting mechanism includes a second housing, and the interior of the second housing is provided with a second drive mechanism that can adjust the height of the tensioning mechanism.

[0008] Preferably, the first drive mechanism includes a first motor, a first rotating shaft is fixedly disposed at the output end of the first motor, a helical blade is fixedly disposed on the outer side of the first rotating shaft, and the rotating wheel is engaged with the helical blade through a tooth groove.

[0009] Preferably, the buffer assembly includes a fixed seat, a connecting seat, and a limiting seat. The fixed seats are circular and fixedly disposed inside the rotating wheel. The connecting seat and the limiting seat are circular and fixedly disposed outside the sleeve. A spring is fixedly disposed between the fixed seat, the connecting seat, and the limiting seat.

[0010] Preferably, the springs are provided in two sets.

[0011] Preferably, a sensor assembly is fixedly installed on one side of the support arm, and the sensor assembly consists of a tension sensor, a speed sensor and a displacement sensor.

[0012] Preferably, the second drive mechanism includes a first screw, a threaded sleeve is threaded on the outer side of the first screw, a gear is fixedly disposed on the upper outer side of the threaded sleeve, a second screw is meshed on the outer side of the gear, the second screw is fixedly disposed at the output end of the second motor, a limiting component is provided on the outer side of the first screw, the second screw is fixedly disposed at the bottom of the first housing, and a programmable logic controller is fixedly disposed on the outer side of the second housing.

[0013] Preferably, a positioning seat is fixedly provided at the bottom of the second outer casing.

[0014] Preferably, the limiting component consists of a sliding groove and a limiting rod. The sliding groove is opened on the outside of the first screw, and the limiting rod is fixedly disposed inside the second housing. The limiting rod is movably disposed inside the sliding groove.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively avoids the problem of traditional fixed tensioning wheels being unable to adapt to changes in tension by setting a tensioning mechanism. In use, the device is installed on the belt conveyor using a positioning seat. Through the first drive mechanism, i.e., the spiral blade is fixed to the output end of the first motor, it can realize real-time adjustment of the belt tension. When the belt tension changes due to factors such as belt wear, material load changes, or ambient temperature changes during the operation of the belt conveyor, the first motor starts according to the feedback signal of the sensor component, drives the spiral blade to rotate, and the meshing action of the spiral blade with the tooth groove of the pulley causes the pulley to rotate, thereby driving the tensioning wheel to move outward or inward along the support arm, thereby adjusting the belt tension in real time. Therefore, this belt conveyor can quickly adapt to changes in tension caused by various factors, keep the belt conveyor in the optimal operating state, and improve production efficiency.

[0017] This invention, through its buffer assembly, can absorb and mitigate the impact and vibration caused by changes in tension during the operation of the belt conveyor, thereby reducing damage to the equipment and extending its service life. The spring provides a certain degree of elastic compensation, ensuring that the tensioning wheel does not cause excessive rigid impact on the belt while adjusting the tension, thus reducing noise and improving the smoothness of the belt conveyor's operation.

[0018] This invention, through a lifting mechanism and a second drive mechanism (comprising a first screw, a threaded sleeve, gears, a second screw, and a second motor), achieves rapid and precise adjustment of the tensioning mechanism's height. When belt tension needs adjustment, the second motor starts according to the PLC control signal, driving the second screw to rotate. Through gear meshing, the first screw moves up and down along the threaded sleeve, thereby raising or lowering the entire tensioning mechanism to adapt to different working conditions. Therefore, this structure not only significantly shortens adjustment time and reduces operator workload, but also automates tension adjustment through precise PLC control, improving the automation level and production efficiency of the production line.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-4 A belt conveyor tension intelligent control device, comprising:

[0027] The tensioning mechanism 1 includes a housing, inside which a rotating wheel 102 is rotatably mounted. The outer side of the rotating wheel 102 is circular and has toothed grooves 103. A first drive mechanism for driving the rotating wheel 102 to rotate is installed inside the housing. The first drive mechanism includes a first motor 106, with a first rotating shaft 104 fixedly mounted at the output end of the first motor 106. A helical blade 105 is fixedly mounted on the outer side of the first rotating shaft 104. The rotating wheel 102 meshes with the helical blade 105 through the toothed grooves 103. A second rotating shaft 108 is rotatably mounted inside the housing, with a sleeve 109 fixedly mounted on the outer side of the second rotating shaft 108. The device is mounted on a belt conveyor using a positioning seat. Through the first drive mechanism, i.e., the helical blades fixed at the output end of the first motor, real-time adjustment of the belt conveyor tension can be achieved. When the belt conveyor tension changes due to factors such as belt wear, material load changes, or ambient temperature changes during operation, the first motor starts according to the feedback signal from the sensor assembly, driving the helical blades to rotate. The helical blades mesh with the toothed grooves of the rotating wheel. The meshing action causes the pulley to rotate, which in turn drives the tensioning pulley to move outward or inward along the support arm, thereby adjusting the belt tension in real time. A buffer assembly is installed between the sleeve 109 and the pulley 102. The buffer assembly includes a fixed seat 107, a connecting seat 110, and a limiting seat 112. The fixed seat 107 is circular and fixedly disposed inside the pulley 102. The connecting seat 110 and the limiting seat 112 are circular and fixedly disposed outside the sleeve 109. A buffer is fixedly disposed between the fixed seat 107, the connecting seat 110, and the limiting seat 112. A spring 111 is provided, and a support arm 114 is fixedly installed at one end of the second rotating shaft 108. A tensioning wheel 116 is rotatably installed at one end of the support arm 114. This can absorb and mitigate the impact and vibration caused by the change in tension during the operation of the belt conveyor, reduce damage to the equipment, and extend the service life of the equipment. The spring can provide a certain elastic compensation, so that the tensioning wheel will not cause excessive rigid impact on the belt while adjusting the tension, thereby reducing noise and improving the smooth operation of the belt conveyor.

[0028] Lifting mechanism 2 is installed at the tension control position of the belt conveyor. Lifting mechanism 2 includes a second housing 201. Inside the second housing 201 is a second drive mechanism that can adjust the height of tensioning mechanism 1. The second drive mechanism includes a first screw 203. A threaded sleeve 204 is threaded onto the outer side of the first screw 203. A gear 205 is fixedly mounted on the upper outer side of the threaded sleeve 204. A second screw 208 is meshed onto the outer side of the gear 205. The second screw 208 is fixedly mounted at the output end of the second motor 209. The outer side of the first screw 203 is provided with… The limiting assembly, the second screw 208 is fixedly installed at the bottom of the first housing 101, and a programmable logic controller 210 is fixedly installed on the outside of the second housing 201. Through the cooperation of the second drive mechanism, namely the first screw, the threaded sleeve, the gear, the second screw and the second motor, the height of the tensioning mechanism can be quickly and accurately adjusted. When it is necessary to adjust the tension of the belt conveyor, the second motor is started according to the control signal of the PLC, driving the second screw to rotate. Through the meshing of the gear, the first screw moves up and down along the threaded sleeve, thereby driving the tensioning mechanism to rise or fall as a whole.

[0029] Example 1: Two sets of springs 111 are provided. A sensor assembly 115 is fixedly provided on one side of the support arm 114. The sensor assembly 115 consists of a tension sensor, a speed sensor and a displacement sensor. The tension sensor is used to monitor the tension of the belt in real time. The speed sensor monitors the running speed of the belt conveyor. The displacement sensor measures the displacement of the tensioning device to determine the tension of the belt.

[0030] Example 2: A positioning seat 202 is fixedly provided at the bottom of the second housing 201. The limiting component consists of a sliding groove 206 and a limiting rod 207. The sliding groove 206 is opened on the outside of the first screw 203, and the limiting rod 207 is fixedly provided inside the second housing 201. The limiting rod 207 is located inside the sliding groove 206 and is movably arranged. The limiting component can make the first screw move up and down smoothly, thereby increasing stability.

[0031] Working Principle: Through a precise mechanical structure and intelligent control system, real-time and automatic adjustment of belt tension is achieved. The working principle is as follows: When the sensor assembly 115 detects a change in belt tension, speed, or displacement, it sends a feedback signal to the programmable logic controller 210. The PLC issues instructions according to the preset program, starting the first motor 106 and the second motor 209. The first motor 106 drives the spiral blade 105 to rotate, which meshes with the tooth groove 103 of the pulley 102, driving the pulley to rotate. This, in turn, adjusts the belt tension through the support arm 114 and the tensioning wheel 116. Meanwhile, the buffer assembly includes a fixed base 107, a connecting base 110, and a limiting base. 112 and spring 111 absorb and mitigate the impact and vibration during the adjustment process, protecting the equipment and extending its service life. The second motor 209 drives the first screw 203 to move up and down within the threaded sleeve 204 through the meshing of gear 205 and the second screw 208, thereby achieving precise adjustment of the height of the tensioning mechanism 1. The limiting assembly, including the slide 206 and the limiting rod 207, ensures the smooth lifting and lowering of the first screw 203, increasing the stability of the adjustment process. Through this design, the device can automatically maintain the optimal tension during the operation of the belt conveyor, improving the operating efficiency and reliability of the belt conveyor, while reducing the labor intensity and maintenance costs of the operators.
