Description

Technical Field

[0001] The utility model relates to the technical field of tension control of production equipment, and particularly relates to a belt conveyor tensioning device. Background Art

[0002] The tensioning device of a belt conveyor is usually a device that keeps the belt running under appropriate tension. This device can adjust the tension of the belt to ensure that the belt will not be loose or too tight during the operation of the belt conveyor, thus ensuring the normal operation of the belt conveyor and extending the service life of the belt.

[0003] The current tensioning device usually uses a tensioning roller and a telescopic driving component to complete the belt tensioning. The driving component can be an electric push rod or a linear movement structure driven by a driving motor, and the position of the tensioning roller abutted against the belt is adjusted by using the telescopic function of the electric push rod or the linear movement structure. The problems existing in the above tensioning device are as follows: the tensioning roller abuts against the surface of the belt, and the belt will continuously move forward during work. During the long-term movement process, the electric push rod or the linear movement structure will be compressed inward, making the belt loose again, and thus the conventional tensioning device needs to be adjusted periodically. Summary of the Utility Model

[0004] The utility model provides a belt conveyor tensioning device, which is used for fixing the tensioning device after the tensioning adjustment is completed, so as to prevent the belt from becoming loose during long-term use.

Specific Embodiments

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, so as to have a further understanding of the concept of the present utility model, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought about.

[0020] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a belt conveyor tensioning device, the belt conveyor 1 is connected with a belt 3 through a driving motor 2, a support rod 4 is installed on the belt conveyor 1, including a mounting plate 5, and two adjusting frames 6 are installed on the mounting plate 5; the adjusting frame 6 passes through the mounting plate 5 and is slidably connected with the mounting plate 5 in the horizontal direction, and a tensioning roller 7 is arranged on the mounting plate 5; an electric telescopic rod 9 is installed at the bottom of the adjusting frame 6, a moving plate 10 is installed at the output end of the electric telescopic rod 9, and sliders 11 are respectively sleeved at the left and right ends of the moving plate 10; further included are two first connecting rods 12, one ends of the two first connecting rods 12 are respectively hinged to the two sliders 11, and the other ends of the two first connecting rods 12 are respectively hinged to the left and right ends of the adjusting frame 6; the two sliders 11 are also respectively connected with clamping blocks 13 through a second connecting rod 14, the two clamping blocks 13 respectively pass through the left and right ends of the adjusting frame 6 and are slidably connected with the adjusting frame 6 in the horizontal direction; the support rod 4 passes through the adjusting frame 6, and the inner ends of the two clamping blocks 13 are aligned with the support rod 4.

[0021] The problem existing in the current tensioning device is that the tensioning roller 7 abuts against the surface of the belt 3, and the belt 3 will continuously move forward during operation. During the long-term moving process, the electric push rod or the linear moving structure will be compressed inward, making the belt 3 become loose again, so that the conventional tensioning device needs to be adjusted periodically.

[0022] The improvement of the present utility model lies in: fixing the adjusted tensioning roller 7 and the adjusting frame 6 to prevent the belt 3 from becoming loose during long-term use. Two adjusting frames 6 are installed on the mounting plate 5. The adjusting frame 6 is slidably connected to the mounting plate 5 in the horizontal direction. The tensioning roller 7 on the adjusting frame 6 abuts against the upper surface of the lower belt 3, and the height of the tensioning roller 7 is lower than the height of the roller connecting the belt 3. Tensioning process: Move the two adjusting frames 6 horizontally towards the two ends of the belt conveyor 1 respectively. When the belt 3 is in a just-tensioned state, fix it using the electric telescopic rod 9. The output end of the electric telescopic rod 9 moves upward, driving the moving plate 10 to move upward synchronously. Two sliders 11 slidably connected to the left and right ends of the moving plate 10 in the horizontal direction are respectively connected to the two ends of the adjusting frame 6 by the first connecting rod 12. During the upward movement of the moving plate 10, the two sliders 11 will move towards the middle of the moving plate 10 relative to the moving plate 10 at the same time. The two sliders 11 move the two pressing plates towards the inside of the adjusting frame 6 through the second connecting rod 14, clamping the support rod 4 from both sides respectively, thereby completing the fixation. In the conventional single-drive extrusion fixation, it mostly abuts against the belt conveyor 1 on one side, which requires a high driving source and has a poor fixation effect. The fixation method of the present utility model is different from the conventional fixation method. Taking a single adjusting frame 6 as an example, it is controlled by a single driving source. Through structural conversion, the two pressing blocks are simultaneously squeezed inward from both sides for fixation, which requires a lower driving source and has a better fixation effect.

[0023] Preferably, the adjusting frame 6 is in a square frame shape. The mounting plate 5 includes a left side plate 61, a right side plate 62, a top plate 63 and a bottom plate 64; the left side plate 61 and the right side plate 62 respectively pass through the through grooves at the left and right ends of the mounting plate 5 and are slidably connected to the mounting plate 5. The adjusting frame 6 is in a square frame shape, with a simple and light structure, which is convenient for passing through the mounting plate 5 and for adjustment.

[0024] Furthermore, it further includes a support plate 65. The support plate 65 is located below the top plate 63. One end of the support plate 65 is connected to the left side plate 61, and the other end of the support plate 65 is connected to the right side plate 62; the tensioning roller 7 is located between the top plate 63 and the support plate 65. One end of the tensioning roller 7 is connected to the left side plate 61, and the other end of the tensioning roller 7 is connected to the right side plate 62. The support plate 65 is installed at the middle position of the adjusting frame 6. Both ends of the support plate 65 are respectively connected to the left side plate 61 and the right side plate 62, providing internal support for the square-frame-shaped adjusting frame 6 and increasing the strength.

[0025] As Figure 5As shown, further, one end of the top plate 63 and the support plate 65 are respectively fixedly connected to the right side plate 62, and the other ends of the top plate 63 and the support plate 65 are respectively connected to the left side plate 61 through a disassembly component 8 with the same structure; the disassembly component 8 includes a hinge seat 81, a lock plate 82 is hinged on the hinge seat 81, a lock hole is provided on the lock plate 82, lock seats 83 are provided on the top plate 63 and the support plate 65, and a lock block 84 passes through the lock hole and is inserted into the lock seat 83. The left side plate 61 is provided with the disassembly component 8 to be respectively connected to the top plate 63 and the support plate 65, which facilitates the quick disassembly and quick fixation of the adjusting frame 6 and is convenient for the maintenance and replacement of the tension roller 7.

[0026] Further, two support blocks 15 are installed on the inner side surface of the left side plate 61, and the two support blocks 15 respectively abut against the bottoms of the top plate 63 and the support plate 65. The two support blocks 15 are respectively arranged at the bottoms of the top plate 63 and the support plate 65 to provide support for the disassembled ends of the top plate 63 and the support plate 65, and also facilitate the alignment of the lock plate 82 with the lock seat 83 during the locking process of the lock seat 83 after disassembly.
