Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a belt conveyor slippage detection device. Background Art

[0002] Belt conveyors are currently widely used across various industries. With the continuous development of automation and information technology, the requirements for hardware equipment are becoming increasingly stringent. In actual production, different types of transported materials place varying and stringent demands on the structure and performance of conveyor belts. In actual production, belts are prone to aging or expansion and contraction due to long-term outdoor use, which can cause slippage between the belt and the drive motor. This slippage often causes material blockage, and excessive material blockage can pull up the belt, causing significant inconvenience and equipment damage. Furthermore, belt slippage can be difficult to detect, impacting production. Utility Model Content

[0003] In order to solve the problem in the prior art that belt conveyor slippage is not easy to be detected, the utility model provides a belt conveyor slippage detection device to achieve the purpose of facilitating the detection of belt slippage.

[0004] The technical solution adopted by the utility model of a belt conveyor slip detection device is:

[0005] A belt conveyor slippage detection device includes a roller group and a roller frame for mounting the roller group, a stopper parallel to the roller group is provided on the outward edge of the roller group, and a proximity switch cooperating with the stopper is provided on the side of the roller frame corresponding to the stopper, and the proximity switch is connected to an alarm light through a relay; wherein the length of the stopper is less than the distance between the side of the roller group on which the stopper is mounted and the inner wall of the roller frame on which the proximity switch is mounted.

[0006] A further improvement of the technical solution of the present utility model is that: the roller group includes a bottom roller rotatably set on a roller frame and parallel to the ground, and the roller frame is located on both sides of the bottom roller and is rotatably provided with inclined side rollers; wherein, the stop block is set on the edge of one of the side rollers facing outward, and the stop block is parallel to the axis of the connected side roller.

[0007] A further improvement of the above technical solution of the present invention is that: the stopper is cylindrical with a diameter of 8 mm and a height of 8 mm.

[0008] A further improvement of the above technical solution of the present invention is that the side of the edge roller on which the stopper is installed is 10 mm away from the inner wall of the roller frame on which the proximity switch is installed.

[0009] A further improvement of the above technical solution of the present invention is that the distance between the side of the stop block away from the corresponding edge roller and the proximity switch is at least 8 mm.

[0010] A further improvement of the technical solution of the present utility model is that: a track is provided at the bottom of the roller frame, a connecting block is slidably provided on the track, and a mounting rod for mounting the proximity switch is vertically provided on the top of the connecting block; wherein, the proximity switch is arranged on the top of the mounting rod, and the relay and the alarm light are fixedly connected to the side wall of the mounting rod.

[0011] A further improvement of the above technical solution of the present invention is that: a slide groove matching the track is provided at the position of the connecting block corresponding to the track, a threaded hole connected to the slide groove is provided at the position of the front side of the connecting block corresponding to the slide groove, and a screw is threadedly connected to the threaded hole.

[0012] A further improvement of the above technical solution of the present invention is that the direction of the sliding groove is perpendicular to the direction of the threaded hole.

[0013] Due to the adoption of the above technical solution, the technical advancements achieved by the present invention include:

[0014] In the utility model, when the block blocks the proximity switch, the proximity switch is closed, and the warning light is powered on and flashes.

[0015] When the belt conveyor is running and there is no slippage between the belt and the roller group, the belt will drive the roller group to rotate at a uniform speed, and the rotating roller group will drive the block to rotate at a uniform speed. The block that rotates at a uniform speed will block the proximity switch in sequence at regular intervals, so that the alarm light will be powered on and flash regularly. When there is slippage between the belt and the roller group, the roller group will not rotate, and the block will not rotate at this time. There are two situations for the block. One is that the block is stationary and does not block the proximity switch. At this time, the alarm light does not flash for a long time. The other situation is that the block is stationary and blocks the proximity switch. At this time, the alarm light is powered on and lit for a long time. When workers observe that the alarm light does not flash or is powered on and lit for a long time, they know that the belt is slipping and the belt needs to be repaired.

[0016] In the utility model, by arranging the track, the connecting block and the screw rod, the position of the connecting block on the track can be conveniently adjusted, thereby driving the proximity switch to move and conveniently adjusting the distance between the proximity switch and the stopper.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concept of the present invention.

[0025] First reference Figure 1 and Figure 2 ,according to Figure 1 and Figure 2 It can be seen that the utility model includes a roller frame 2 arranged on the ground, and a roller group 1 rotatably arranged on the roller frame 2, a belt is provided on the roller group 1, and a detection mechanism is provided on the roller group 1 for detecting whether slippage occurs between the belt and the roller group 1.

[0026] The above roller group 1 can continue to refer to the specific setting Figure 1 and Figure 2 ,according to Figure 1 and Figure 2 It can be seen that the roller group 1 includes a bottom roller 11 located above the middle of the roller frame 2, parallel to the ground and rotatably connected to the roller frame 2. At the same time, side rollers 12 rotatably connected to the roller frame 2 are arranged at an angle on both sides of the bottom roller 11. Specifically, each side roller 12 is connected to the roller frame 2 through a support frame 21, and the distance between the end of the side roller 12 and the inner wall of the corresponding support frame 21 is 10 mm.

[0027] The detection mechanism in the present invention includes a stopper 3 fixedly arranged (such as by welding or other fixing methods) on the outer edge of a side roller 12. The stopper 3 is parallel to the axis of the corresponding side roller 12. The stopper 3 is cylindrical, and the diameter of the stopper 3 is 8 mm and the height is 8 mm. Figure 1 and Figure 2 The detection mechanism also includes a proximity switch 4 located outside the edge roller 12 where the block 3 is provided. The distance between the proximity switch 4 and one end of the outer side of the block 3 is at least 8 mm, and the above-mentioned proximity switch 4 is also connected to an alarm light 5 through a relay 6.

[0028] The proximity switch 4 in the utility model can be further referred to when specifically setting it. Figure 1 ,according to Figure 1 It can be seen that the bottom of the roller frame 2 is fixedly connected (such as by welding, bolt connection, etc.) with a horizontal track 7, a connecting block 8 is slidably connected to the track 7, and the top of the connecting block 8 is fixedly connected with a vertical mounting rod 9, and the proximity switch 4 is located at the top of the mounting rod 9; continue to refer to Figure 1 , the relay 6 and the warning light 5 are respectively mounted on the side walls of the mounting rod 9.

[0029] The connection block 8 in the utility model can be referred to in the specific setting Figure 3 ,according to Figure 3 It can be seen that a slide groove 81 that cooperates with the track 7 is provided at the bottom of the connecting block 8, so that the connecting block 8 can move along the track 7, and a threaded hole 82 that is perpendicular to the slide groove 81 and connected to the slide groove 81 is provided on the front side of the connecting block 8. The above-mentioned connecting block 8 is threadedly connected to a screw rod 83 through the threaded hole 82. When the connecting block 8 moves to a suitable position on the track 7, the screw rod 83 can be rotated so that one end of the screw rod 83 located at the connecting block 8 is in contact with the track 7, thereby fixing the connecting block 8 on the track 7 to prevent the proximity switch 4 from moving when the utility model is in use.

[0030] In the present invention, all components that require electricity are connected to an external power supply, thereby being powered by the external power supply. The specific connection method can be carried out by those skilled in the art according to actual conditions, and will not be described in detail here.

[0031] The working principle of the automatic bag breaking device of this embodiment is: when the utility model is used, the belt will drive the roller group 1 to rotate at a constant speed, and the rotating roller group 1 will drive the block 3 to rotate at a constant speed. The block 3 rotating at a constant speed will block the approach switch 4 in sequence at regular intervals, so that the alarm light 5 will be powered on and flash regularly. When the alarm light 5 is powered on and flashes regularly, it means that there is no slippage between the roller group 1 and the belt.

[0032] When the belt slips between the roller group 1, the roller group 1 does not rotate. At this time, there are two situations for the block 3. One is that the block 3 is stationary and does not block the proximity switch 4. At this time, the alarm light 5 does not flash for a long time; the other situation is that the block 3 is stationary and blocks the proximity switch 4. At this time, the alarm light 5 is powered on and lit for a long time. When the worker observes that the alarm light 5 does not flash or is powered on and lit for a long time, he knows that the belt is slipping and the belt needs to be repaired.

[0033] In the above embodiment, the utility model provides a belt conveyor slippage detection device, which can drive the block to rotate through the set roller group, and the rotating block can block the proximity switch. When the block rotates at a constant speed, the proximity switch closes periodically and the alarm light flashes periodically, which indicates that the belt conveyor has not slipped; when the block does not rotate, the proximity switch does not close or is closed for a long time, and the alarm light does not flash or is powered on and lit for a long time, which indicates that the belt conveyor has slipped and needs to be processed.

[0034] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
