Description

Technical Field

[0001] The invention relates to the field of belt conveyors, and in particular to an automatically adjustable belt turning device for belt conveyors. Background Art

[0002] For long-distance belt conveyors, the belt turning device is an essential component. The function of the belt turning device is to turn over the working and non-working surfaces of the conveyor belt to prevent the residue on the working surface from rubbing against the rollers during operation and causing loss, ensuring that the non-working surface is always in contact with the rollers, and maintaining the stability of the belt conveyor.

[0003] Today's belt turning devices are usually manual, floating or completely fixed. The angle of the belt turning device is adjusted by a manual wheel, or the appropriate turning angle is calculated and then fixed. On the one hand, these belt turning devices are labor-intensive to adjust, and the second adjustment after fixing once is time-consuming and labor-intensive. On the other hand, the position of the belt turning depends on the accuracy of the calculation. If the belt turning device is not adjusted in place, it will cause excessive tension on the belt and pressure on the support roller bracket, increase wear on the belt, and easily cause deviation.

[0004] The position and tension calculation of the belt turning device is a very complex process. The tension of the belt conveyor changes constantly during operation, and there is no good feedback for different belt speeds, different transport volumes, different operating times and changes in the surrounding environment. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides an automatically adjustable belt-turning device for a belt conveyor to solve at least one of the above-mentioned technical problems.

[0006] The technical solution of the present invention is: an automatically adjustable belt conveyor belt turning device, comprising a belt turning mechanism, characterized in that the belt turning mechanism comprises a driving screw, the driving screw is fixed on the steel structure of the belt conveyor, a connecting support is provided on the driving screw, the driving screw is connected to the movable frame through the connecting support, and the driving screw drives the movable frame to move in the vertical direction through the driving device;

[0008] A roller is fixed on the movable roller bracket, and an adhesive tape is transmitted on the roller.

[0009] When in use, connect the belt turning device to the main steel structure. First, adjust the movable frame to a suitable height through the driving screw. When the tape passes through the belt turning device, the movable roller bracket can be adjusted to the preset position through the toothed disc driver. After the adjustment is completed, the movable frame and the movable roller bracket are locked through the driving screw and the toothed disc driver to maintain the working stability. When the working condition of the tape changes, the tape tension also changes accordingly. At this time, the driving screw and the toothed disc driver can be unlocked, and the tape tension acts on the movable roller bracket. The change in tension will cause the position of the belt surface to change. By adjusting the roller bracket regulator, the tape is always located at the relative center of the roller. The change in tape tension will also drive the toothed disc to rotate, and the change in tension will also cause the height of the tape surface to change, which also drives the movement of the movable frame. After the tape conveyor runs stably, each drive device is locked to maintain a stable working state. This cycle continues.

[0010] Further preferably, there are four toothed disc drivers, and the four toothed disc drivers are respectively located around the toothed disc, so that the toothed disc can be moved in all directions in an all-round manner.

[0011] Further preferably, a damper is fixed on the toothed disc driver, and the damper fits with the edge of the toothed disc.

[0012] The damper serves to cushion the rotation of the gear disc.

[0013] Further preferably, two fixed roller brackets arranged opposite to each other are welded on the toothed disc, thereby playing a limiting role.

[0014] Further preferably, the driving screw is arranged on both sides of the movable frame, and each driving screw is equipped with two connecting supports, and the two connecting supports are arranged up and down on the driving screw, so that the movable bracket can be better fixed on the steel structure, and the two connecting supports can better fix the movable frame.

[0015] Further preferably, the buffer hooks are provided in eight groups, with three in each group, and the buffer hooks are respectively fixed on the four sides of the toothed disc.

[0016] Further preferably, the buffer hook includes a hook, the hook passes through the movable frame, a fastener is provided at one end of the hook, a support wheel is provided at the other end of the hook, the fastener is located at the connection between the hook and the movable frame, a groove for connecting the hook is provided on the toothed disk, a baffle is provided on the groove, and the support wheel is abutted against the inner wall of the baffle.

[0017] The present invention can realize the movement of the frame through the hook.

[0018] Further preferably, a spring is provided at the connection between the fastener and the bottom of the movable frame.

[0019] Thereby, the activity effect of the activity framework can be optimized.

[0020] More preferably, the seven belt turning mechanisms are used together as a group to complete the entire process of turning over the adhesive tape, the seven belt turning mechanisms are arranged at intervals, and the inclination angles of the movable roller brackets of the seven belt turning mechanisms are 22.5°, 45°, 67.5°, 90°, 67.5°, 45°, and 22.5°, respectively. The seven belt turning mechanisms are used together to complete the entire process of turning over the adhesive tape.

[0021] Further preferably, the inclination angles of the movable roller brackets of the seven belt turning mechanisms gradually decrease from the middle to the two ends.

[0022] Beneficial effects:

[0023] 1. The device realizes the automation of the adjustment of the belt turning device. The adjustment can be completed automatically through the set control program. There is no need to assign professional personnel to the site for debugging.

[0024] 2. The natural feedback mechanism is used to solve the complex calculation process. The accuracy of the equipment installation position is improved. The belt is kept in a good state of operation, which is conducive to reducing the wear of the belt and thus increasing the service life of the belt. Since the cost of the belt accounts for a high proportion of the investment cost of the belt conveyor and it is a vulnerable material, extending the service life of the belt can achieve considerable economic benefits.
