[0039] The utility model will be explained in detail below in combination with specific embodiments. The following embodiments will help the person skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that, for the person skilled in the art, on the premise of not departing from the utility model concept, a number of changes and improvements can be made. These all belong to the protection scope of the utility model.

[0040] To solve the problems such as material leakage or belt scratch damage caused by belt deviation, the utility model provides a belt deviation adjusting mechanism, as shown in Figure 1 、 Figure 2 The deviation adjusting support plate 13, the support 14 and one or more deviation running idlers 12 are included, and the deviation adjusting support plate 13 is arranged on the support 14.

[0041] Specifically, the upper end of the deflection adjusting support plate 13 is sequentially provided with a plurality of clamping grooves 131 in the width direction, and the deflection adjusting support plate 13 is parallel to the axial direction of the support 14, that is, the deflection adjusting support plate 13 is arranged in a vertical or nearly vertical direction to the main shaft of the deflection roller 12.

[0042] As shown in Figure 2 The upper part of the deflection roller 12 is provided with a return belt 112, and the deflection roller 12 is used to support and guide the movement of the return belt 112. The two ends of the main shaft of the deflection roller 12 are arranged in the clamping grooves 131, and the angle between the deflection roller 12 and the return belt 112 can be adjusted by adjusting the two ends of the main shaft of the deflection roller 12 in different clamping grooves 131, thereby achieving the effect of correcting the deviation.

[0043] Specifically, when the belt does not deviate, the deflection roller 12 main shaft two ends select the clamping groove 131, and the deflection roller 12 needs to be adjusted to a vertical angle with the belt, as shown in Figure 5 The angle between the deflection roller 12 and the right edge of the return belt 112 is 90°, at this time, the deflection roller 12 only plays a supporting and guiding role, and does not play a correcting role.

[0044] Further, when the belt deviates to the left, the deflection roller 12 main shaft two ends select the clamping groove 131, and the deflection roller 12 needs to be adjusted to an angle that is not perpendicular to the belt, as shown in Figure 6 The angle between the deflection roller 12 and the right edge of the return belt 112 needs to be adjusted to a position greater than 90°, at this time, the belt is gradually adjusted to the right under the driving of the axial friction of the deflection roller 12, thereby achieving the effect of correcting the deviation.

[0045] Further, when the belt deviates to the right, the deflection roller 12 main shaft two ends select the clamping groove 131, and the deflection roller 12 needs to be adjusted to an angle that is not perpendicular to the belt, as shown in Figure 7 The angle between the deflection roller 12 and the right edge of the return belt 112 needs to be adjusted to a position less than 90°, at this time, the belt is gradually adjusted to the right under the driving of the axial friction of the deflection roller 12, thereby achieving the effect of correcting the deviation.

[0046] It should be noted that by adjusting the clamping groove 131 where the main shaft of the deflection roller 12 is placed, the movement direction of the return belt 112 can be adjusted, and at the same time, the movement direction of the outgoing belt 111 is also adjusted, which is conducive to the adjustment of the overall movement direction of the belt.

[0047] Specifically, the clamping groove 131 can be designed in various structures, for example, it can be a semicircular groove or a rectangular groove. When the belt is running, the main shaft of the deflection roller 12 does not rotate, and the roller outside the main shaft rotates around the main shaft under the driving of the belt to achieve the supporting and guiding effect, therefore, the shape of the end of the main shaft should match the shape of the clamping groove 131 to increase the stability effect.

[0048] Specifically, the alignment support plate 13 can be fixed in various ways. In one possible embodiment, the alignment support plate 13 is directly welded to the bracket 14, providing good stability. In another possible embodiment, the alignment support plate 13 is detachably mounted to the bracket 14 by bolts, allowing for installation and removal of the alignment support plate 13 at any time by unscrewing the bolts. In yet another possible embodiment, the alignment support plate 13 is fixed to the bracket 14 by lugs 18, with one end of the lugs 18 welded to the bracket 14 and the bottom of the alignment support plate 13 detachably mounted on the other end of the lugs 18. Therefore, there are multiple ways to fix the alignment support plate 13, which can be reasonably selected according to the actual situation. For large belts, the torque on each component during operation is relatively large, and the alignment support plate 13 may be frequently deformed and damaged. In this case, a detachable assembly method can be selected. If the materials and thicknesses of the alignment support plate 13 and the bracket greatly meet the strength requirements of actual operation, the possibility of deformation or damage to the alignment support plate 13 is relatively low. Therefore, the alignment support plate 13 can be configured with a fixed assembly form such as welding to meet the actual needs.

[0049] In practical applications, a misalignment idler 12 and two misalignment adjustment plates 13 set at both ends of the misalignment idler 12 together form a misalignment adjustment assembly. For long-distance belt conveyors, it is very difficult to achieve misalignment correction with a single misalignment adjustment assembly. Therefore, multiple misalignment adjustment assemblies are included. These multiple misalignment adjustment assemblies are arranged at equal intervals along the length of the conveyor belt 11. By using multiple misalignment adjustment assemblies together to correct the misalignment, local or overall misalignment correction can be achieved, meeting the actual needs of production.

[0050] When the deviation adjustment component alone is insufficient to correct the deviation, anti-deviation guide wheels 15 can be installed on both sides of the outgoing belt 111, such as... Figure 3 As shown, a set of anti-deviation guide wheels 15 is set on each side of the belt to form a group. By setting multiple groups, the effect of auxiliary deviation correction can also be achieved.

[0051] This utility model also provides a conveyor belt, which employs a belt misalignment adjustment mechanism. For example... Figure 1 As shown, the conveyor belt 11 includes a going belt 111 and a returning belt 112. The going belt 111 is located above the returning belt 112 and together they form a circular motion structure. The bottom of the going belt 111 is supported and guided by idlers. The bottom of the going belt 111 has a first idler 16 located in the middle and second idlers 17 arranged on both sides of the first idler 16. The going belt 111 arranged on the first idler 16 and the second idler 17 forms a structure with a high bottom edge in the middle, which can prevent material leakage during transportation.

[0052] The driving roller at the head provides rotating power, the redirection roller at the tail supports redirection, and finally realizes the closed-loop transmission movement of the transmission belt 11.

[0053] It should be noted that the belt deviation adjusting mechanism in the utility model can be arranged below the return belt 112, and can also be arranged below the outgoing belt 111, and the corresponding deviation correction effect can be realized.

[0054] The working principle of the utility model is as follows:

[0055] When the belt does not deviate, the two ends of the main shaft of the deviation roller 12 are perpendicular to the belt by selecting appropriate clamping grooves 131, as shown in the figure, at this time, the deviation roller 12 only plays a supporting and guiding role, and does not play a deviation correction role. Figure 5

[0056] When the belt deviates to the left, the angle between the deviation roller 12 and the right edge of the return belt 112 needs to be adjusted to a position greater than 90 degrees by selecting the clamping grooves 131 at both ends of the main shaft of the deviation roller 12, as shown in the figure, at this time, the belt is gradually adjusted to the right under the drive of the axial friction of the deviation roller 12, and plays a deviation correction and supporting and guiding role. Figure 6

[0057] When the belt deviates to the right, the angle between the deviation roller 12 and the right edge of the return belt 112 needs to be adjusted to a position less than 90 degrees by selecting the clamping grooves 131 at both ends of the main shaft of the deviation roller 12, as shown in the figure, at this time, the belt is gradually adjusted to the right under the drive of the axial friction of the deviation roller 12, and plays a deviation correction and supporting and guiding role.
