[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] When existing belt conveyors are in use, they need to transport items via belts. In actual operation, the belts fixed by belt fixing devices may need to transport items of different weights. This may cause the belt tension to be insufficient to meet the conveying requirements, resulting in reduced friction between the belt and the rollers. Consequently, the conveyor belt may not be able to keep in sync with the rollers, leading to slippage and deviation. This situation may cause the belt conveyor to malfunction or even completely lose its conveying function.
[0024] In view of this, the present invention provides a belt fixing device for a belt conveyor. This belt fixing device for a belt conveyor, through the cooperation of a hydraulic cylinder, a transmission plate, a connecting rod, a connecting plate, and a connecting block, enables timely adjustment of the belt tension according to actual needs. This solves the problem that in the operation of existing belt conveyors, when conveying items by belt, the belt fixed by the belt fixing device may need to convey items of different masses. This may cause the belt tension to be insufficient to meet the conveying requirements, resulting in reduced friction between the belt and the roller. Consequently, the conveyor belt may not be able to keep synchronous with the roller, leading to slippage and deviation. This situation may cause the belt conveyor to malfunction or even completely lose its conveying function.
[0025] Example 1, by Figure 1-4 As can be seen, the belt fixing device for a belt conveyor in this case includes a fixing plate 1, a roller 2 is provided on one side of the outer wall of the fixing plate 1, a roller shaft 21 is rotatably connected inside the roller 2 through a sealed bearing, a transmission box 11 is provided between the roller 2 and the fixing plate 1, the side wall of the transmission box 11 is fixedly connected to the side of the outer wall of the fixing plate 1 near the roller 2, and a tensioning assembly 3 is provided inside the transmission box 11. The tensioning assembly 3 includes: a hydraulic cylinder 31, fixedly connected to one side of the inner wall of the transmission box 11, and its output end penetrating through the side wall of the transmission box 11; a transmission plate 32, fixedly connected to the output end of the hydraulic cylinder 31; and a connecting plate 32. Two connecting rods 33 are provided, both fixedly connected to the side of the transmission plate 32 away from the hydraulic cylinder 31; two connecting plates 34 are provided, each sleeved on the outer wall of the two connecting rods 33; two connecting blocks 35 are provided, each inserted into the inner wall of the two connecting plates 34, and their side walls are fixedly connected to both ends of the roller shaft 21; a monitoring unit 36 is provided on the top side of the transmission box 11; wherein, the hydraulic cylinder 31 drives the connecting rods 33 to move through the transmission plate 32, and the connecting rods 33, through the cooperation of the connecting plates 34 and the connecting blocks 35, cause the roller shaft 21 to drive the roller 2 to move, thereby achieving the purpose of changing the tension force;
[0026] In the specific implementation process, it is worth noting that the four corners of the fixing plate 1 are provided with through holes, which makes it easy for the staff to install the belt fixing device for the belt conveyor onto the conveyor. The side wall of the transmission box 11 is provided with four through holes to facilitate the movement of the limit rod 321. The roller 21 is a non-powered roller and needs to be used in conjunction with the power roller on the other side of the belt conveyor. The model of the hydraulic cylinder 31 is selected according to actual needs, as long as it meets the working requirements. The transmission plate 32 has a trapezoidal cross section, the connecting rod 33 is L-shaped, the connecting plate 34 is rectangular with two through holes on its surface, and the connecting block 35 is rectangular. The connecting block is fixed to the outer wall of the side away from the roller 21 to facilitate the limiting of the connecting plate 34. Through the cooperation between the hydraulic cylinder 31, the transmission plate 32, the connecting rod 33, the connecting plate 34 and the connecting block 35, the tension of the belt on the belt conveyor can be changed, thereby increasing the applicability of the belt fixing device for the belt conveyor and improving the practicality of the belt conveyor.
[0027] Furthermore, a horizontal plate 111 is fixedly connected to the top of the transmission box 11. The monitoring unit 36 includes: a slide rail 361, fixedly connected to the top of the horizontal plate 111; a base 362, slidably engaged with the outer wall of the slide rail 361; a connecting seat 363, fixedly connected to the top of the base 362; a clamping groove 364, rotatably connected to the outer wall of the connecting seat 363 via a sealed bearing; a second threaded hole 365, located at the top of the clamping groove 364; a second bolt 366, threadedly connected to the inner wall of the second threaded hole 365; a mounting base 367, rotatably connected to the bottom of the second bolt 366 via a sealed bearing; and a sensor 368, mounted at the bottom of the mounting base 367. The monitoring unit 36 can change its position and orientation through the slide rail 361, the base 362, and the connecting seat 363, and through the cooperation of the clamping groove 364, the second bolt 366, and the sensor 368, the monitoring unit 36 can monitor the tension of the belt in a timely manner.
[0028] In the specific implementation process, it is worth noting that the slide rail 361 has a T-shaped cross-section, the base 362 is a cuboid, and the bottom of the base 362 has a T-shaped groove that matches the slide rail 361, allowing the base 362 to move. The slide rail 361 and the base 362 are limited by fixing bolts. The connecting seat 363 is cylindrical, and the clamping groove 364 is C-shaped with a circular groove at the bottom center. The clamping groove 364 cooperates with the connecting seat 363 to allow the clamping groove 364 to rotate. Fixing grooves are provided on both sides of the circular groove. The fixing grooves cooperate with the fixing rod 4 to limit the clamping groove 364. The sensor 368 is selected according to actual needs, as long as it meets the working requirements. For example, it can be a resistance strain gauge sensor. Through the cooperation of the second bolt 366, the second threaded hole 365 and the sensor 368, the belt tension can be monitored in a timely manner, thereby increasing the functionality and convenience of the belt fixing device for belt conveyors.
[0029] Furthermore, a vertical plate 6 is fixedly connected to one side of the horizontal plate 111, and a receiver 61 and a controller 62 are installed side by side on the outer wall of the vertical plate 6 away from the horizontal plate 111.
[0030] In the specific implementation process, it is worth noting that the model of receiver 61 can be selected according to actual needs, as long as it meets the requirements of operation. Receiver 61 is used in conjunction with sensor 368 to monitor belt tension. The model of controller 62 can also be selected according to actual needs, as long as it meets the requirements of operation. Controller 62 is used to control hydraulic cylinder 31, thereby enhancing the operational stability and ease of use of the belt fixing device used for belt conveyors.
[0031] Specifically, when it is necessary to change the belt tension, the operator connects the external power supply to the controller 62 and starts the controller 62. Through the controller 62, the external power supply to the hydraulic cylinder 31 is connected, and the hydraulic cylinder 31 is started. The output end of the hydraulic cylinder 31 drives the transmission plate 32 to move. The transmission plate 32 drives the two connecting rods 33 to move. The two connecting rods 33 drive the two connecting plates 34 to move. The two connecting plates 34 drive the two connecting blocks 35 to move. The connecting blocks 35 drive the roller shaft 21 to move. The roller shaft 21 drives the roller 2 to move. The roller shaft 21 drives the belt mounted on its surface to move. When it is necessary to change the belt tension again, the above operation can be repeated. Through the cooperation of the above components, the tension of the belt on the belt conveyor can be changed, the applicability of the belt fixing device used for the belt conveyor can be improved, and the practicality of the belt conveyor can be improved. When it is necessary to monitor the belt tension, the operator connects the external power supply to the receiver 61 and starts the receiver 61. At the same time, the operator squeezes the second... Bolt 366 is rotated clockwise. The second bolt 366 moves the mounting base 367, which in turn moves the sensor 368 until it contacts the belt surface. The sensor senses the belt deformation and converts it into an electrical signal, which is then transmitted to the receiver 61 to measure the belt tension. The operator observes the belt tension on the display on the receiver 61. When monitoring belt tension is not required, the operator rotates the second bolt 366 counterclockwise to remove the sensor 368 from the belt surface. When monitoring the tension on the other side of the belt is required, the operator rotates the screw at the bottom of the base 362 clockwise, changing the position of the base 362 via the slide rail 361. This increases the functionality and convenience of the belt fixing device for belt conveyors.
[0032] Example 2, by Figure 1-4It is known that the base 362 has a through groove 3622 inside, and the outer walls of the base 362 have grooves 3621 on both sides. The inner walls of the two grooves 3621 are fixedly connected to springs 3623, and the ends of the two springs 3623 are fixedly connected to limit blocks 3624. The outer walls of the two limit blocks 3624 are respectively inserted into the inner walls of the two grooves 3621. The outer walls of the two limit blocks 3624 are fitted with fixing rods 4. The tops of the two fixing rods 4 are respectively inserted into the reserved slots on both sides of the bottom of the clamping groove 364. The bottoms of the two fixing rods 4 are fixedly connected to crossbars 41, and the outer walls of the crossbars 41 are inserted into the inner walls of the through groove 3622.
[0033] In the specific implementation process, it is worth noting that the fixed rod 4 is L-shaped in general, and the end is easy for the staff to move. It has a through hole in the middle and a trapezoidal cross section to facilitate its cooperation with the limiting block 3624. The side of the limiting block 3624 away from the spring 3623 is round, which also facilitates its cooperation with the through hole on the fixed rod 4. The spring 3623 is made of carbon spring steel. The elastic coefficient of the spring 3623 is selected according to actual needs to meet the working requirements. The crossbar 41 slides in the through groove 3622 to limit the fixed rods 4 on both sides, thereby improving the structural stability of the belt fixing device used for belt conveyors.
[0034] Furthermore, the outer wall of the connecting rod 33 is provided with a first threaded hole 331, and a first bolt 341 is inserted into the top of the connecting plate 34. The first bolt 341 passes through the connecting plate 34, and the outer wall of the first bolt 341 is threaded to the inner wall of the first threaded hole 331.
[0035] In the specific implementation process, it is worth noting that five first threaded holes 331 are provided on a connecting rod 33. The first threaded holes 331 cooperate with the first bolts 341 to change the distance between the two connecting plates 34, thereby further improving the functionality of the belt fixing device for belt conveyors.
[0036] Furthermore, a limiting rod 321 is fixedly connected to the outer wall of the transmission plate 32 near the transmission box 11. The outer wall of the limiting rod 321 is inserted into the side wall of the transmission box 11 and is movably connected to the side wall of the transmission box 11.
[0037] In the specific implementation process, it is worth noting that the limiting rod 321 is T-shaped as a whole, and there are four of them. The end of the limiting rod is located inside the transmission box 11. The limiting rod 321 limits the distance of movement of the transmission plate 32, thereby further improving the structural stability of the belt fixing device used for belt conveyors.
[0038] Furthermore, brackets 5 are fixed on the outer walls of the two connecting plates 34 away from the roller 2, and pulleys 51 are installed on the outer walls of the two brackets 5.
[0039] In the specific implementation process, it is worth noting that the bottom of the bracket 5 is equipped with support feet. By rotating the support feet, the bracket 5 can be raised or lowered. When it is necessary to change the belt tension or to move the belt fixing device for the belt conveyor as a whole, the two pulleys 51 can assist in the work, thereby further improving the operational stability and ease of use of the belt fixing device for the belt conveyor.
[0040] Specifically, when rotating the clamping groove 364 as needed, the operator presses down on the limiting blocks 3624 on both sides with one hand, compressing the spring 3623. The other hand rests on the bottom of the fixing rod 4 and pulls it downwards, causing the fixing rod 4 to leave the bottom fixing groove of the clamping groove 364. When the fixing rod 4 moves below the limiting block 3624, the spring 3623 rebounds, simultaneously pushing the limiting block 3624 back into position. At this point, the hand pressing the limiting block 3624 leaves the limiting block 3624, pinches the clamping groove 364, and rotates it 180 degrees, thus achieving the steering function. The hand resting on the bottom of the fixing rod 4 pushes it upwards, returning it to the bottom fixing groove of the clamping groove 364. The side wall of the limiting block 3624 enters the through hole according to the trajectory of the through hole on the fixing rod 4, thus achieving the limiting function. Through the cooperation of the above parts, the efficiency for leather is improved. The structural stability of the belt fixing device for the conveyor is improved by rotating the first bolts 341 on both sides counterclockwise. The first bolts 341 move away from the first threaded holes 331. At this time, the distance between the two connecting plates 34 can be changed, which further improves the functionality of the belt fixing device for the conveyor. When the hydraulic cylinder 31 moves the transmission plate 32, the limit rod 321 moves with the transmission plate 32 and limits the distance the transmission plate 32 moves, which further improves the structural stability of the belt fixing device for the conveyor. The bracket 5 supports the roller 2 and the roller shaft 21. When it is necessary to change the belt tension or move the belt fixing device for the conveyor as a whole, the two pulleys 51 can assist in the work, which further improves the operational stability and ease of use of the belt fixing device for the conveyor.
