[0030] See Figures 1-4The belt pressing device for the belt conveyor in this embodiment can effectively prevent the conveyor belt 3 from becoming slack, jumping, or running off-center during operation, as well as the conveyor belt 3 from warping at turning points, thereby improving the operational stability of the entire conveying system. Furthermore, compared to existing technologies, the belt pressing method of this invention does not occupy space on both sides of the conveyor belt 3, does not narrow the conveying range, and does not affect conveying efficiency. In this embodiment, it mainly includes a first conveyor 1 and a second conveyor 2 arranged opposite to each other. The first conveyor 1 is placed horizontally, and the second conveyor 2 is placed obliquely upwards. The first conveyor 1 and the second conveyor 2 share a single conveyor belt 3. Support frames 6 are vertically fixed on both sides of the first conveyor 1 and the second conveyor 2. Multiple conveyor rollers 7 are rotatably mounted on the inner ring of the conveyor belt 3 on both the first conveyor 1 and the second conveyor 2. The conveyor belt 3 is fitted onto the conveyor rollers 7 of the first conveyor 1 and the second conveyor 2. The first conveyor 1 and the second conveyor 2 are fixed in height and position by the support frames 6, while the bottom end of the second conveyor 2 is flush with the first conveyor 1.

[0031] To achieve belt pressing of conveyor belt 3. See [link / reference] Figures 2-4 In this embodiment, a liftable pressure roller 4 is horizontally arranged at the opposite ends of the first conveyor 1 and the second conveyor 2. The pressure roller 4 is located at the top of the outer ring of the conveyor belt 3 and abuts against the top of the conveyor belt 3. The height of the pressure roller 4 is lower than the height of the conveyor belt 3 of the first conveyor 1. The conveyor belt 3 above the conveyor roller 7 of the first conveyor 1 passes under the pressure roller 4 and connects to the top of the conveyor roller 7 of the second conveyor 2. At this time, the conveyor belt 3 at the position of the pressure roller 4 forms a downward concave shape. Thus, when the first conveyor 1 and the second conveyor 2 are working, the conveyor belt 3 is tightly attached to the conveyor roller 7 under the action of the pressure roller 4, avoiding the phenomenon of the conveyor belt 3 becoming loose, jumping, or running off-center, as well as the phenomenon of the conveyor belt 3 lifting at the turning point, which would affect the operational stability of the entire conveying system.

[0032] A vibration damping roller 8 is horizontally positioned below the pressure roller 4. The vibration damping roller 8 is located within the inner ring of the conveyor belt 3 and abuts against the bottom end of the conveyor belt 3. Auxiliary rollers 9 are horizontally positioned on both sides between the pressure roller 4 and the vibration damping roller 8, and these auxiliary rollers abut against the bottom end of the outer ring of the conveyor belt 3. The conveyor belt 3 below the transmission roller 7 of the first conveyor 1 passes over the auxiliary roller 9 on the side of the first conveyor 1 and then descends below the vibration damping roller, passing over the side of the second conveyor 2. At this time, the conveyor belt 3 winds upwards from the left side of the auxiliary roller 9 on the side of the second conveyor belt 3 and connects to the bottom of the transmission roller 7 of the second conveyor 2 from above the auxiliary roller 9. The lower conveyor belt 3 is located between the two auxiliary rollers 9 and at the bottom end of the vibration damping roller, forming a downwardly concave shape. This further stabilizes the operating state of the conveyor belt 3, reduces potential risks caused by vibration, and improves operational safety.

[0033] To achieve the lifting and lowering of the pressure roller 4, in this embodiment, see... Figure 2 and Figure 4 An adjustment mechanism 5 for driving the pressure roller 4 to rise and fall is fixedly installed at the end of the first conveyor 1. The adjustment mechanism 5 includes vertically fixed slide rails 51 on the support frames 6 at both ends of the first conveyor 1, with the slide rails 51 positioned at the opposite ends of the first conveyor 1 and the second conveyor 2. Sliding blocks 52 are slidably mounted on the slide rails 51, and both ends of the pressure roller 4 are rotatably connected to the corresponding sliding blocks 52. Both ends of the anti-vibration roller 8 and the auxiliary roller 9 are rotatably connected to the corresponding sliding blocks 52. A top plate 53 is fixedly installed at the top of the support frame 6, and a bottom plate 54 is fixedly installed on the support frame 6 below the sliding blocks 52. Multiple mounting holes 55 are vertically opened on the top plate 53, and the bottom plate 54 has an L-shaped structure, with the mounting holes 55 also located at the vertical ends of the bottom plate 54. The top plate 53 and the bottom plate 54 are fixed to the support frame 6 by inserting bolts into the mounting holes 55.

[0034] A lead screw 56 is vertically threaded onto a sliding block 52 at one end of the pressure roller 4. The top of the lead screw 56 passes through a top plate 53, and an adjusting plate 57 is fixedly mounted on the top of the lead screw 56. The bottom of the lead screw 56 passes through a bottom plate 54 and is rotatably connected to the bottom plate 54. When the position of the pressure roller 4 needs to be adjusted, rotating the adjusting plate 57 drives the lead screw 56 to rotate, thereby causing the sliding block 52 threadedly connected to it to rise and fall on the slide rail 51. A guide rod 58 is vertically slidably mounted on the sliding block 52 at the other end of the pressure roller 4. The top of the guide rod 58 is fixedly mounted to the top plate 53, and the bottom of the guide rod 58 is fixedly mounted to the bottom plate 54. A linear bearing 59 is fixedly mounted on the sliding block 52 and sleeved on the guide rod 58. The linear bearing 59 reduces the frictional resistance of the sliding block 52 when it rises and falls on the guide rod 58. When the lead screw 56 drives the sliding block 52 to rise and fall, the sliding block 52 at the other end of the pressure roller 4 rises and falls on the guide rod 58 through the linear bearing 59 under the action of the pressure roller 4, the auxiliary roller 9, and the anti-vibration roller, thereby ensuring the horizontality of the pressure roller 4, the auxiliary roller 9, and the anti-vibration roller.

[0035] The method of using the belt pressing device for the belt conveyor of this utility model is as follows: First, the conveyor belt 3 is fitted onto the conveyor rollers 7 of the first conveyor 1 and the second conveyor 2. The first conveyor 1 and the second conveyor 2 are fixed in height and position by the support frame 6, and the bottom end of the second conveyor 2 is flush with the first conveyor 1. The top plate 53 and the bottom plate 54 are fixed to the support frame 6 by inserting bolts into the mounting holes 55.

[0036] When the first conveyor 1 and the second conveyor 2 are operating, the conveyor belt 3 above the conveyor roller 7 of the first conveyor 1 passes under the pressure roller 4 and connects to the top of the conveyor roller 7 of the second conveyor 2. At this time, the conveyor belt 3 at the pressure roller 4 position forms a downward concave shape. This ensures that when the first conveyor 1 and the second conveyor 2 are operating, the conveyor belt 3 is tightly pressed against the conveyor roller 7 under the action of the pressure roller 4, preventing the conveyor belt 3 from becoming loose, jumping, or running off-center, or from lifting up at the turning point, which would affect the operational stability of the entire conveying system. The conveyor belt 3 below the conveyor roller 7 of the first conveyor 1 passes over the auxiliary roller 9 on the side of the first conveyor 1 and then goes down and around the side of the second conveyor 2 from under the anti-vibration roller. At this time, the conveyor belt 3 goes up from the left side of the auxiliary roller 9 on the side of the second conveyor 1 and connects to the bottom of the conveyor roller 7 of the second conveyor 2 from above the auxiliary roller 9. At this time, the lower conveyor belt 3 is located between the two auxiliary rollers 9 and at the bottom end of the anti-vibration roller, forming a downward concave shape. This further stabilizes the operation of conveyor belt 3, reduces potential risks caused by vibration, and improves operational safety.

[0037] When the position of the pressure roller 4 needs to be adjusted, the adjusting plate 57 is rotated to drive the lead screw 56 to rotate, thereby causing the sliding block 52, which is threadedly connected to it, to rise and fall on the slide rail 51. When the lead screw 56 drives the sliding block 52 to rise and fall, the sliding block 52 at the other end of the pressure roller 4, under the action of the pressure roller 4, the auxiliary roller 9, and the anti-vibration roller, rises and falls on the guide rod 58 through the linear bearing 59, thereby ensuring the horizontality of the pressure roller 4, the auxiliary roller 9, and the anti-vibration roller.
