[0030] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0031] Referring to Figure 1 And Figure 2 The figure shows one example of the conveying belt deviation detection and correction device provided by the utility model.

[0032] As shown in the figure, the conveying belt deviation detection and correction device of the present example cooperates with the roller assembly 300 and the conveying belt 400 arranged on the roller assembly 300, mainly including a correction device 100 and a detection device 200.

[0033] The deviation rectifying device 100 forms elastic dynamic contact with the conveying belt 400, can timely push the deviated conveying belt 400 back to the center line position, realizes timely deviation rectification, and the detection device 200 can reflect the deviation working condition of the conveying belt 400 and timely remind the staff.

[0034] In combination Figures 2 to 5 Specifically, the deviation rectifying device 100 is arranged on the carrier roller assembly 300 through the mounting frame 110 arranged on both sides of the carrier roller assembly 300, and the deviation rectifying device 100 comprises the vertical roller 120 symmetrically arranged on both sides of the conveying belt 400, so that the vertical roller 120 can correspond to the conveying belt 400 and cooperate with the mounting frame 110 to realize timely deviation rectification of the conveying belt 400.

[0035] Further, the working surface of the vertical roller 120 is provided with the guide limiting groove 130 matched with the side edge 410 of the conveying belt 400, and the extension center line of the guide limiting groove 130 is consistent with the extension center line of the side edge 410 of the conveying belt 400, so that when the conveying belt 400 deviates, the side edge 410 of the conveying belt 400 can be synchronously moved laterally and moved into the guide limiting groove 130 to abut and cooperate with the groove bottom of the guide limiting groove 130, thereby limiting the conveying belt 400, so that the guide limiting groove 130 limits the deviation amount of the conveying belt 400.

[0036] Meanwhile, the deviation gap is arranged between the guide limiting groove 130 and the side edge 410 of the conveying belt 400, allowing the conveying belt 400 to deviate in a small range within the deviation gap, ensuring stable and smooth movement of the conveying belt 400.

[0037] Preferably, the groove wall of the guide limiting groove 130 is provided with a buffer layer, or the vertical roller 120 is entirely composed of a rubber roller, so as to reduce the abutting friction between the conveying belt 400 and the guide limiting groove 130 and improve the service life of the conveying belt 400.

[0038] In order to reduce the friction loss of the conveying belt 400, the vertical roller 120 is configured to be elastically connected with the mounting frame 110 in sliding mode, so that the vertical roller 120 can be synchronously rotated when the conveying belt 400 moves, thereby reducing the friction loss of the conveying belt 400 in the guide limiting groove 130 and rectifying the conveying belt 400.

[0039] In combination Figure 3 and Figure 4Specifically, the vertical roller 120 is elastically connected with the mounting frame 110 through the elastic connecting piece 140, the elastic connecting piece 140 is arranged at both ends of the vertical roller 120, and includes a spring telescopic rod 141 and a fixed supporting rod 142, the fixed supporting rod 142 is arranged in the vertical roller 120 and extends out of the vertical roller 120 at both ends and is connected with the spring telescopic rod 141, so that the vertical roller 120 can rotate around the fixed supporting rod 142, meanwhile, a spring is sleeved on the spring telescopic rod 141, and one end of the spring is connected with the mounting frame 110 and the other end is connected with the fixed supporting rod 142, so that the spring telescopic rod 141 and the fixed supporting rod 142 cooperate to stably and elastically connect the vertical roller 120 with the mounting frame 110.

[0040] In this way, when the conveying belt 400 deviates and abuts against the guide limiting groove 130, the vertical roller 120 will be driven to rotate around the fixed supporting rod 142 along with the continuous transportation of the conveying belt 400, thereby reducing the friction loss of the guide limiting groove 130 to the conveying belt 300.

[0041] In combination Figure 2 Meanwhile, when the conveying belt 400 deviates and abuts against the guide limiting groove 130, a lateral pressure will be generated on the vertical roller 120, the vertical roller 120 will be driven to move towards the mounting frame 110, the spring telescopic rod 141 will be compressed synchronously, the spring telescopic rod 141 will be elongated to the initial state under the elastic restoring force of itself, a force opposite to the lateral pressure will be generated on the vertical roller 120, and the vertical roller 120 will be synchronously driven to move away from the mounting frame 110, thereby driving the conveying belt 400 to return to the initial center line position and timely correct the deviation.

[0042] In combination Figure 3 And Figure 4 In order to improve the connection stability of the vertical roller 120 and the mounting frame 110, the elastic connecting piece 140 is further slidably connected with the mounting frame 110 through the guide connecting piece 150, so that the elastic connecting piece 140 and the guide connecting piece 150 cooperate to ensure the stable movement of the vertical roller 120.

[0043] Specifically, the end of the guide connecting piece 150 matched with the vertical roller 120 is provided with a concave clamping groove 151 matched with the vertical roller 120, the end matched with the mounting frame 110 is provided with a guide rod 152, and the mounting frame 110 is provided with a guide groove hole 111 matched with the guide rod 152 in a gap, so that the guide rod 152 is inserted into the guide groove hole 111 and can move axially along the guide groove hole 111, the vertical roller 120 is accommodated in the concave clamping groove 151, and the vertical roller 120 can rotate in the concave clamping groove 151.

[0044] Meanwhile, the two end faces of the concave clamping groove 151 extend towards the spring telescopic rod 141 and are arranged on the spring telescopic rod 141, so that the elastic connecting piece 140 and the guide connecting piece 150 are stably connected, so that when the conveying belt 400 deviates and drives the vertical roller 120 to move towards the mounting rack 110, or when the spring telescopic rod 141 pushes the vertical roller 120 away from the mounting rack 110, the guide connecting piece 150 will be driven to move axially along the guide slot hole 111 to approach or move away from the mounting rack 110, so as to guide and limit the movement direction of the vertical roller 120, prevent the vertical roller 120 from deviating during movement and correction, and ensure the correction reliability of the conveying belt 400. The conveying belt 400 is stably driven to return to the initial center line position.

[0045] The correction device 100 thus formed, the vertical roller 120 is connected with the mounting rack 110 through the elastic connecting piece 140 and the guide connecting piece 150, not only can ensure the synchronous movement of the vertical roller 120 and the conveying belt, reduce the friction loss of the conveying belt 400, but also can form elastic dynamic contact between the vertical roller 120 and the conveying belt 400, and correct the conveying belt 400 in time under the action of elastic restoring force, so as to improve the reliability of the correction device 100.

[0046] In combination Figures 1 to 5 In the present example, the conveying belt 400 includes a transportation conveying belt 420 and a return conveying belt 430 arranged on the upper region and the lower region of the roller assembly 300 respectively, in order to ensure the correction of the whole conveying belt 400 and reduce the overall friction loss of the conveying belt 400, the correction device 100 includes a first group of vertical rollers 121 and a second group of vertical rollers 122 which are matched with the transportation conveying belt 420 and the return conveying belt 430 respectively, so that the first group of vertical rollers 121 and the second group of vertical rollers 122 can be matched with the mounting rack 110 respectively and correct the transportation conveying belt 420 and the return conveying belt 430 synchronously.

[0047] As an example, the transportation conveying belt 420 is in U-shaped distribution, the first group of vertical rollers 121 is arranged on the upper region of the roller assembly 300 through the mounting rack 110, and the vertical rollers 120 arranged on both sides of the transportation conveying belt 420 in the first group of vertical rollers 121 also correspond to U-shaped distribution, the extension center line of the guide limiting slot 130 in the first group of vertical rollers 121 is consistent with the extension center line of the side edge of the transportation conveying belt 420, so as to ensure the effective cooperation between the first group of vertical rollers 121 and the transportation conveying belt 420 and improve the correction effect of the transportation conveying belt 420.

[0048] Correspondingly, the return conveying belt 430 is horizontally distributed, the second group of stand rollers 122 are arranged in the lower area of the carrier roller assembly 300 through the mounting frame 110, and the stand rollers 120 arranged on both sides of the return conveying belt 430 in the second group of stand rollers 122 are also horizontally distributed. The extension center line of the guide limiting groove 130 in the second group of stand rollers 122 is consistent with the extension center line of the side edge of the return conveying belt 430, which ensures the effective cooperation between the second group of stand rollers 122 and the return conveying belt 430 and improves the deviation correction effect on the return conveying belt 430.

[0049] Thus, timely deviation correction of the conveying belt 400 as a whole is ensured, and the friction loss of the conveying belt 400 can be effectively reduced.

[0050] In order to ensure the deviation correction reliability, the device further comprises a detection device 200 arranged on the mounting frame 110 and configured to detect the lateral pressure value borne by the stand roller 120 in real time to issue an alarm information and timely remind the staff.

[0051] In combination with Figure 6 Specifically, the detection device 200 can be composed of an existing pressure sensor and includes a pressure sensing unit 210 and a signal processing unit 220, so that the detection device 200 is arranged on the mounting frame 110 and connected to the stand roller 120. The pressure sensing unit 210 detects the lateral pressure value generated by the conveying belt 400 on the stand roller 120 in real time, so as to obtain the deviation working condition of the conveying belt 400. The greater the lateral pressure value is, the greater the deviation of the conveying belt 400 is.

[0052] Further, the pressure sensing unit 210 transmits the lateral pressure value to the signal processing unit 220 in real time. The signal processing unit 220 is pre-set with a pressure threshold value, so that the signal processing unit 220 compares and judges the lateral pressure value with the pressure threshold value. If the lateral pressure value is greater than the pressure threshold value, it means that the deviation of the conveying belt 400 is too large, and the stand roller 120 cannot effectively push the conveying belt 400 back to the center line position under the elastic restoring force of the elastic connecting piece 140. At this time, the signal processing unit 220 generates an alarm instruction.

[0053] Here, the pressure threshold value in the signal processing unit 220 is adapted to the maximum deviation of the conveying belt 400 and the elastic restoring force of the elastic connecting piece 140, so that when the lateral pressure value borne by the stand roller 120 is the pressure threshold value, the stand roller 120 cannot effectively push the conveying belt 400 back to the center line position.

[0054] In combination therewith, the device further comprises an alarm device configured to receive the alarm instruction to issue corresponding alarm information.

[0055] Here, the alarm device can be composed of a sound and light alarm arranged on the mounting frame 110 to issue sound and light alarm information, which can timely and effectively remind the staff to manually intervene the conveying belt 400, and ensure the deviation correction effect of the conveying belt 400.

[0056] The detection device 200 thus formed can detect the lateral pressure value of the edgeroll 120 in real time, timely reflect the deviation working condition of the conveying belt 400, and improve the reliability of the device.

[0057] In the present example, the detection device 200 cooperates with each edgeroll in the first group of edgerolls 121 and the second group of edgerolls 122 respectively to synchronously detect the lateral pressure value of each edgeroll, thereby effectively obtaining the deviation working condition of the two sides of the transport conveying belt 420 and the return conveying belt 430, timely reflecting the deviation amount of the whole conveying belt 400, and ensuring the working stability of the conveying belt 400.

[0058] The conveying belt deviation detection and correction device provided by the present application is in elastic dynamic contact with the conveying belt 400, so that the conveying belt 400 abuts against the guide limiting groove 130 on the edgeroll 120 when deviating, generates a lateral pressure on the edgeroll 120, moves the edgeroll 120 facing the mounting frame 110, compresses the elastic connecting member 140, thereby generating a reverse thrust on the edgeroll 120 under the action of elastic restoring force, pushes the conveying belt back to the initial center line position, and thus realizes timely deviation correction of the conveying belt.

[0059] Meanwhile, the detection device 200 detects the lateral pressure value of the conveying belt 400 on the edgeroll 120 in real time to obtain the deviation working condition of the conveying belt, issues an alarm information, timely reminds the staff, and ensures the reliability of the device.

[0060] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application.
