[0002] Belt conveyor is the abbreviation of belt conveyor, which has fixed and mobile types, simple structure and high efficiency. It is a continuous conveying machine with flexible conveyor belt as material carrying and traction component. During the transportation process, the belt conveyor will cause the belt to sag and detach from the original conveying roller surface due to the appearance of slope change points, resulting in the phenomenon of floating belt, which will cause the belt surface parts to fall off due to unstable transportation.

[0003] In the prior art, pressure wheels are usually installed on both sides of the belt conveyor to prevent the belt from falling off during operation. However, it is usually necessary to pre-open bolt holes on both sides of the belt conveyor and then use bolts to install and fix the pressure wheels. This method cannot adjust the position of the belt pulley and is difficult to install and disassemble the pressure wheel. In addition, most of the existing pressure wheels are fixed structures, and it is difficult to adjust the clamping force between the belt and the belt. Excessive pressure will cause the belt to deform, resulting in reduced transmission efficiency, while too little pressure will not have a clamping effect on the belt, which has certain limitations.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a belt conveyor belt pressing device, including a belt conveyor bracket 1 and a base 2, a mounting groove 101 is provided on the top of the belt conveyor bracket 1, and both sides of the inner wall of the mounting groove 101 are provided with limiting grooves 102, and both sides of the outer wall of the base 2 are provided with grooves 201, a first turning handle 3 is movably installed on the top of the base 2, and both sides of the base 2 are movably installed with a second turning handle 4, a mounting block 5 is provided at one end of the base 2, and a connecting plate 51 is fixedly installed at both ends of the mounting block 5, a slider 52 is fixedly installed on one side of the outer wall of the connecting plate 51, and a pressing wheel is provided at one end of the mounting block 5 6. A connecting shaft 61 is fixedly connected to one side of the pressure wheel 6, and one end of the connecting shaft 61 is movably connected to the inner wall of the mounting block 5. A connecting rod 31 is fixedly connected to the bottom of the first turning handle 3, and a screw 32 is fixedly connected to the bottom of the connecting rod 31. The bottom of the screw 32 is movably connected to the bottom end of the inner wall of the base 2. A threaded sleeve 33 is threadedly connected to the surface of the screw 32, and both sides of the threaded sleeve 33 are movably connected to a movable rod 34. Two rectangular blocks 35 are provided inside the base 2, and one side of the rectangular block 35 is movably connected to the bottom end of the movable rod 34, and the other side of the rectangular block 35 is fixedly connected to a friction block 36.

[0024] In this embodiment, the base 2 is placed on the inner side of the installation groove 101 and the first turning handle 3 on the top is turned. The first turning handle 3 drives the connecting rod 31 and the screw 32 at the bottom to rotate. The rotation of the screw 32 causes the threaded sleeve 33 to move on its surface. While the threaded sleeve 33 moves downward, the bottom ends of the movable rods 34 on both sides squeeze the rectangular block 35 outward, so that the rectangular block 35 and the friction block 36 are located on the inner side of the limiting groove 102, and the clamping wheel 6 on the side of the base 2 is located on the top of the belt. At this time, the base 2 cannot be removed from the inner side of the installation groove 101, and the installation of the base 2 is completed. Example

[0025] like Figure 1-Figure 5 As shown, a guide rod 21 is fixedly installed on the inner wall of the groove 201, and a spring 22 is provided on the surface of the guide rod 21. The inner wall of the slider 52 is slidably connected to the surface of the guide rod 21, and the slider 52 is located at the bottom of the spring 22. One end of the second turning handle 4 is fixedly connected to a bevel gear 1 41, and a round rod 42 is movably connected to the bottom of the inner wall of the base 2. A bevel gear 2 43 is fixedly installed on the surface of the round rod 42, and a screw 2 44 is fixedly connected to the top of the round rod 42. The surface of the bevel gear 1 41 is movably connected to the inner wall of the base 2, and one side of the bevel gear 1 41 is meshed with one side of the bevel gear 2 43. A support block 45 is movably installed on the inner side of the groove 201, and the top of the support block 45 is fitted with the bottom of the slider 52, and the inner wall of the support block 45 is threadedly connected to the surface of the screw 2 44.

[0026] In this embodiment, when the base 2 is installed and fixed, the pressure wheel 6 is in contact with the belt to play a pressure role. By rotating the second handle 4, the second handle 4 drives the bevel gear 1 41 to rotate, and the bevel gear 1 41 engages with the bevel gear 2 43, so that it drives the round rod 42 and the screw 2 44 to rotate. The rotation of the screw 2 44 causes the support block 45 to move on its surface. The support block 45 rises on the surface of the screw 2 44 and pushes up the slider 52. The slider 52 drives the pressure wheel 6 to rise, which is convenient for adjusting the pressure between the pressure wheel 6 and the belt.

[0027] The working principle of this embodiment is as follows: the base 2 is placed inside the installation groove 101, and the first turning handle is turned to drive the connecting rod 31 and the screw rod 1 32 at the bottom to rotate. The rotation of the screw rod 1 32 causes the threaded sleeve 33 to move on its surface. While the threaded sleeve 33 moves downward, the bottom ends of the movable rods 34 on both sides squeeze the rectangular block 35 outward, so that the rectangular block 35 and the friction block 36 are located inside the limiting groove 102, and the installation of the base 2 is completed. The second turning handle 4 is turned to drive the bevel gear 1 41 to rotate, and the bevel gear 2 43 drives the round rod 42 and the screw rod 2 44 to rotate. The support block 45 rises on the surface of the screw rod 2 44, and at the same time lifts up the slider 52 and the clamping wheel 6, so as to facilitate the adjustment of the clamping force between the clamping wheel 6 and the belt.
