Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a novel belt conveyor drum adhesive detection device. Background Technique

[0002] During the operation of the belt conveyor, the situation of belt deviation often occurs. At this time, the materials on the traveling belt will fall onto the return belt and then be transported to the tail drum. In winter in the north, the weather is relatively cold and the materials are relatively moist, so the materials will be compacted, frozen and accumulate thicker and thicker at the tail drum; the drum sticking material will cause the conveyor belt to bulge, posing a hidden danger of scratching the conveyor belt; to solve this problem, generally enterprises only adopt the method of installing a cleaner on the return belt to scrape off the return belt material and avoid the drum sticking material; however, in actual use, the cleaner cannot completely clean the return belt material, and sometimes the cleaner will malfunction, so sometimes it will still cause the tail drum to stick material. Therefore, a drum adhesive detection device is needed to give an alarm in time when the sticking material occurs to avoid greater equipment damage; in this regard, this application proposes a novel belt conveyor drum adhesive detection device. Content of the Utility Model

[0003] The purpose of the utility model is to provide a novel belt conveyor drum adhesive detection device to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A novel belt conveyor drum adhesive detection device, including a frame, a drum installed in the frame, and a belt drivingly connected to the outside of the drum. A drum guard is fixedly connected to one side of the frame. The drum is located inside the drum guard. A limit bracket is fixedly installed by embedding on the right side of the drum guard. A roller type travel switch is fixedly installed inside the limit bracket. When the belt bulges due to the drum adhering to the material, the bulging belt squeezes the roller part of the roller type travel switch, so that the roller type travel switch is squeezed and triggered to transmit a shutdown alarm signal.

[0005] Preferably, an embedding hole is opened on the right side of the drum guard, and the front inner wall and the rear inner wall of the embedding hole are respectively fixedly connected to the front side and the rear side of the limit bracket.

[0006] Preferably, the roller type travel switch is located to the right of the middle of the right side of the drum.

[0007] Preferably, a signal line is fixedly connected and electrically connected to the right side of the roller type travel switch.

[0008] Preferably, the drum is provided with a driving motor installed on the frame, and the driving motor is electrically connected to an external PLC control device for driving control.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. This is a new type of belt conveyor roller sticking material detection device. Through the coordination of the roller travel switch, signal line, roller guard, roller and belt, it can automatically transmit the shutdown alarm signal to trigger the shutdown alarm when there is a lot of material accumulation on the roller at the tail end of the conveyor. After seeing the alarm, the company's on-duty personnel will immediately arrange to clean up the accumulated material and eliminate the hidden dangers of failure. The alarm is used to remind personnel, so that they can be informed and cleaned in time, which greatly reduces the risk of the roller material scratching the belt, ensures the working efficiency and avoids the loss of the company's property.

[0011] The utility model can automatically transmit a shutdown alarm signal to trigger a shutdown alarm when there is a lot of material accumulated on the drum.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 As shown, a novel belt conveyor roller sticking detection device proposed in this embodiment includes a frame, a roller 1 installed in the frame and a belt 2 drivingly connected to the outside of the roller 1, a roller guard 3 is fixedly connected to one side of the frame, the roller 1 is located in the roller guard 3, a limit bracket 4 is embedded and fixed on the right side of the roller guard 3, a roller type travel switch 5 is fixedly installed in the limit bracket 4, and the roller part of the roller type travel switch 5 is in active contact with the right side of the belt 2; when the roller 1 is attached with material and the belt 2 is bulged, the bulged belt 2 is used to squeeze the roller part of the roller type travel switch 5, so that the roller type travel switch 5 is squeezed and triggered, and the roller type travel switch 5 is used to transmit a shutdown alarm signal when it is triggered; wherein the model of the roller type travel switch 5 is JDHK-1L.

[0016] Specifically, an embedding hole is formed in the right side of the drum guard 3. The front inner wall and the rear inner wall of the embedding hole are respectively fixedly connected to the front side and the rear side of the limit bracket 4, achieving the effect of allowing the limit bracket 4 to pass through and providing fixed support for it.

[0017] Furthermore, the roller type travel switch 5 is located to the right of the middle of the right side of the drum 1.

[0018] Furthermore, a signal line 6 is fixedly connected and electrically connected to the right side of the roller type travel switch 5.

[0019] Furthermore, the drum 1 is cooperatively provided with a driving motor installed on the frame. The driving motor is electrically connected to an external PLC control device for driving control. Among them, the signal line 6 is electrically connected to the PLC control device. When the roller type travel switch 5 is touched, a shutdown alarm signal is transmitted to the PLC controller device through the signal line 6 to perform shutdown and alarm reminder work.

[0020] The usage method of this embodiment is as follows: When the drum 1 adheres to materials, as the accumulated material between the drum 1 at the tail of the conveyor and the belt 2 becomes thicker and thicker, during the conveying operation, it will squeeze the right side of the belt 2 to bulge or cause it to form a bulge. The bulging or right-side bulging belt 2 squeezes the roller part of the roller type travel switch 5, causing the roller type travel switch 5 to be squeezed and touched. The roller type travel switch 5 is used to transmit a shutdown alarm signal to the PLC controller device through the signal line 6 when it is touched, thereby triggering shutdown and alarm reminder work. The company's on-duty personnel immediately arrange to clean the accumulated material and eliminate potential trouble hazards after seeing the alarm, greatly reducing the risk of the drum accumulated material scratching the belt 2, ensuring the operation efficiency and avoiding the loss of the company's property at the same time.

[0021] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
