Description

Technical Field

[0001] This application relates to the field of conveyor belts, and more particularly to a conveyor belt protection device. Background Technology

[0002] Conveyor belts are an important component in the process of handling goods, greatly improving the efficiency of goods transfer and reducing the labor intensity of workers. During the sorting and transfer of goods, multiple side conveyor belts in different directions transfer goods to the main conveyor belt, which then transports the collected goods to the storage area.

[0003] During operation, there is a possibility of collisions between the side conveyor belts and items on the main conveyor belt, which can cause material accumulation or items to fall off the conveyor belt, reducing the stability of item transport and increasing the risk of item damage. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a conveyor belt protection device.

[0005] This application provides a conveyor belt protection device, which adopts the following technical solution:

[0006] A conveyor belt protection device includes a main conveyor belt, a first drive mechanism for driving the main conveyor belt, a side conveyor belt, a second drive mechanism for driving the side conveyor belt, a detection mechanism disposed on the side conveyor belt, and a controller. The detection mechanism is used to detect items on the main conveyor belt. The detection mechanism is signal-connected to the controller, and the controller is electrically connected to the first drive mechanism. When the detection mechanism detects an item on the main conveyor belt, the controller controls the second drive mechanism to stop running.

[0007] By adopting the above technical solution, when the detection mechanism detects that an item on the main conveyor belt is close to the side conveyor belt, the controller controls the second drive mechanism to stop running, thereby reducing the phenomenon of items on the main conveyor belt colliding with items sliding off the side conveyor belt and falling or piling up, thus improving the safety and stability of item transportation and reducing the risk of item damage.

[0008] Preferably, the first driving mechanism includes a first frame, a first motor, a first driving roller, and a first driven roller mounted on the first frame. One end of the first driving roller is fixedly connected to the drive shaft of the first motor, and the other end is rotatably connected to the first frame. Both ends of the first driven roller are rotatably connected to the first frame. Both the first driving roller and the first driven roller are drivenly connected to the main conveyor belt. The second driving mechanism includes a second frame, a second motor, a second driving roller, and a second driven roller mounted on the second frame. One end of the second driving roller is fixedly connected to the drive shaft of the second motor, and the other end is rotatably connected to the second frame. Both ends of the second driven roller are rotatably connected to the second frame. Both the second driving roller and the second driven roller are drivenly connected to the side conveyor belt. The second motor is electrically connected to the controller.

[0009] By adopting the above technical solution, the first motor drives the first drive roller to rotate, thereby driving the main conveyor belt, and the second motor drives the second drive roller to rotate, thereby driving the side conveyor belt. When the detection mechanism detects that an item on the main conveyor belt is close to the side conveyor belt, the controller controls the second motor to stop running, thereby stopping the side conveyor belt from moving and reducing the phenomenon of item collision.

[0010] Preferably, the detection mechanism includes photoelectric sensors disposed on both sides of the main conveyor belt, and the photoelectric sensors are signal-connected to the controller.

[0011] By adopting the above technical solution, the photoelectric sensor is used to detect whether there are items near the side conveyor belt of the main conveyor belt, and transmits the signal to the controller, so that the controller can control the start and stop of the second motor.

[0012] Preferably, the second frame is provided with a barrier bar on the side of the main conveyor belt for blocking items on the side conveyor belt, and a third motor is provided on the second frame. The drive shaft of the third motor is fixedly connected to the barrier bar, and the third motor is electrically connected to the controller.

[0013] By adopting the above technical solution, when the photoelectric sensor detects an item near the side conveyor belt on the main conveyor belt, the controller controls the second motor to stop running. At the same time, the controller controls the third motor to drive the barrier bar to rotate, so that the barrier bar intercepts the item on the side conveyor belt, thereby preventing the item on the side conveyor belt from continuing to slide due to inertia, further reducing the phenomenon of item collision, and further improving the safety and stability of item transportation.

[0014] Preferably, the second frame is provided with two side baffles at one end near the main conveyor belt, and the two side baffles are respectively provided on opposite sides of the second frame.

[0015] By adopting the above technical solution, the two side baffles limit the items on the side conveyor belt, thereby reducing the phenomenon of items slipping off the side conveyor belt and improving the stability of item transportation.

[0016] Preferably, a guide plate is provided at one end of the second frame near the main conveyor belt, and the guide plate is inclined.

[0017] By adopting the above technical solution, the guide plate guides the items on the side conveyor belt, thereby improving the stability of item transfer and reducing the phenomenon of items getting stuck during transfer.

[0018] Preferably, a guide plate is provided on the side of the main conveyor close to the side conveyor belt, and the end of the guide plate close to the side conveyor belt is inclined in the direction of being close to the side conveyor belt.

[0019] By adopting the above technical solution, the guide plate guides and limits the items that slide off the side conveyor belt, so that the items move to the center of the main conveyor belt, thereby reducing the phenomenon of items falling off the main conveyor belt and improving the safety and stability of item transportation.

[0020] Preferably, the guide plate has an installation groove, and a plurality of rotating rollers are provided in the installation groove, with both ends of the rotating rollers being rotatably connected to the guide plate.

[0021] By adopting the above technical solution, the items on the main conveyor belt come into contact with the rotating roller during the movement process. The rotating roller reduces the wear on the items during the guidance process by the guide plate.

[0022] In summary, this application has the following beneficial technical effects:

[0023] 1. When the photoelectric sensor detects that an item on the main conveyor belt is close to the side conveyor belt, the controller stops the second motor, thereby stopping the side conveyor belt. This reduces the occurrence of collisions, falling, or piling of items, improves the safety and stability of the item conveying process, and reduces the risk of item damage.

[0024] 2. When the photoelectric sensor detects that an item on the main conveyor belt is approaching the side conveyor belt, the controller controls the second motor to stop running and simultaneously controls the third motor to drive the guardrail to rotate, so that the guardrail intercepts the item on the side conveyor belt. This reduces the phenomenon that the item on the side conveyor belt continues to slide due to inertia, further reduces the phenomenon of item collision, falling or piling, further improves the safety and stability of the item conveying process, and further reduces the risk of item damage.

[0025] 3. Guide plates move the items to the center of the main conveyor belt, thereby further improving the safety and stability of the item conveying process. Attached Figure Description
