DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the implementation mode and the accompanying drawings. Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model. Example

[0021] Reference Figure 1 , Figure 2 and Figure 3 An automatic deviation correction device for a belt scale comprises a roller channel steel support base 1, and a hanger 11 is welded and fixed to the top of the roller channel steel support base 1.

[0022] A roller support 2 is arranged inside the roller channel steel support base 1, and support plates 21 are fixed at both ends of the roller support 2. A slot 22 is opened on the support plate 21, and a roller 3 is arranged between the two support plates 21. A rotating shaft 31 is fixed at both ends of the roller 3, and the rotating shaft 31 is inserted into the corresponding slot 22.

[0023] A sleeve 4 is fixed at the center of the roller channel steel support base 1, and the sleeve 4 penetrates the roller channel steel support base 1.

[0024] A sleeve shaft 23 is fixed at the bottom center of the roller support 2, and the sleeve shaft 23 is inserted into the sleeve 4 and rotatably connected with the sleeve 4, and the sleeve 4 supports the roller support 2. There is a gap between the outer wall of the sleeve shaft 23 and the inner wall of the sleeve 4, so that the sleeve shaft 23 and the sleeve 4 are not easy to rust.

[0025] The two support plates 21 are both provided with a limit assembly 5 on the side away from each other, and the limit assembly 5 can prevent the rotating shaft 31 from slipping out from the top of the slot 22. The limit assembly 5 includes a limit plate 51, a fixed shaft 52 and a locking bolt 53. The limit plate 51 is located above the rotating shaft 31, and the fixed shaft 52 is fixed on the support plate 21. One end of the limit plate 51 is rotatably connected to the fixed shaft 52, and the other end of the limit plate 51 is fixed to the support plate 21 by the locking bolt 53.

[0026] An arc groove 511 is formed on one side of the limiting plate 51 close to the rotating shaft 31 . The arc groove 511 matches the top arc of the rotating shaft 31 , thereby limiting the vertical position of the rotating shaft 31 and increasing the stability of the rotating shaft 31 .

[0027] Two stop rollers 6 are arranged on one side of the roller channel steel support base 1, and the return belt 9 passes between the two stop rollers 6 after passing through the roller 3. Two support arms 7 are fixed on the roller channel steel support base 1, and each stop roller 6 corresponds to a support arm 7, and a threaded hole 71 is provided on the support arm 7. A support shaft 72 is arranged below the stop roller 6, and the bottom of the support shaft 72 is threadedly connected to the threaded hole 71, and a connecting hole 61 is provided at the center of the stop roller 6. A support sheet 73 is fixed on the outer wall of the support shaft 72, and the upper half of the support shaft 72 is inserted into the connecting hole 61. The support sheet 73 supports the stop roller 6, and the stop roller 6 can rotate around the support shaft 72.

[0028] During the actual operation, after the belt 9 deviates, it scrapes the stop roller 6, and the stop roller 6 rotates accordingly, driving the roller bracket 2 to move in the deviation adjustment direction, so that the belt 9 completes the deviation correction action. After the deviation correction is completed, the belt 9 moves the roller bracket 2 to the original position.

[0029] Because this deviation correction device makes the roller 3 automatically correct its deviation, it gives the belt 9 an upward support force, which reduces the tension of the bearing, reduces the stress on the belt 9, and reduces the occurrence of cracking of the belt 9 due to excessive tension.

[0030] By adopting the automatic belt deviation correction device of the utility model, the belt scale can realize the function of automatic deviation correction, which has a simple structure and is easy to process, solves the problem of belt conveyor deviation and reduces the workload of on-site personnel for adjustment at any time in the event of deviation.

[0031] The implementation principle of the automatic deviation correction device for belt scales of the utility model is as follows: during the operation of the belt 9, the belt 9 deviates and hits the stop roller 6 on one side, and the stop roller 6 rotates on the intermediate shaft of the stop roller 6 with the contact of the belt 9. At this time, the channel steel bracket of the roller 3 leads the roller 3 to tilt along the sleeve shaft 23, and the belt 9 realizes the automatic deviation correction function. When the belt 9 is corrected, the automatic deviation correction device returns to its original position as the belt 9 runs. Example

[0032] Reference Figure 4 , which is different from Example 1, a support assembly 8 for supporting the roller bracket 2 is provided on the roller channel steel bracket base 1, and the support assembly 8 includes a support block 81, and two support blocks 81 are respectively provided on the left and right sides of the sleeve shaft 23, and a plurality of balls 82 are evenly installed on the upper surface of the support block 81, and the balls 82 are in contact with the bottom of the roller bracket 2. When the belt 9 deviates, the roller bracket 2 swings.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
