Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a belt conveyor. Background Technology

[0002] In modern industrial automation and smart logistics scenarios, belt conveyors, as key equipment for continuous material transport, are widely used in fields such as electronic assembly, express sorting, and agricultural product processing. However, with the expansion of production scale and the increasing demand for refined processes, the technical shortcomings of traditional belt conveyors have gradually become apparent. For example, traditional belt conveyor systems often use a shared power source to drive multiple conveyors, which has two major drawbacks: First, when one conveyor malfunctions (such as belt breakage or material jamming), the entire system will stop, affecting production continuity. Second, it cannot achieve differentiated control based on the material type and conveying speed requirements of different workstations. For example, in sorting scenarios, small items need to be conveyed at high speed, while large items need to be conveyed at low speed and steadily; a shared power source cannot meet such flexible requirements. In addition, the control boxes of traditional belt conveyors have limited functionality, mostly equipped with only basic start and stop buttons. When the motor overheats abnormally, it cannot provide timely warnings or automatically stop the machine, posing a safety hazard. At the same time, traditional control boxes are difficult to seamlessly integrate with the PLC control system and sensor network of the production line, failing to meet the requirements of intelligent collaborative control. Therefore, those skilled in the art have provided a belt conveyor to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a belt conveyor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A belt conveyor includes a first belt conveyor, a power transmission structure, and a support structure. A second belt conveyor is arranged parallel to one side of the first belt conveyor. A second fixed plate and a first fixed plate are respectively installed on both sides of the second belt conveyor and the first belt conveyor. The bottoms of the two second fixed plates and the first fixed plate are connected by at least one set of support structures. A first drive shaft and a first driven shaft are rotatably connected to both sides of the interior of the second belt conveyor through bearings. A second drive shaft and a second driven shaft are rotatably connected to both sides of the interior of the first belt conveyor through bearings. A power transmission structure is fixedly connected to the first drive shaft and the second drive shaft respectively.

[0006] As a further embodiment of this utility model: the power transmission structure includes a motor, a first sprocket, a rotating shaft, a second sprocket, and a chain. The power output shaft of the motor is fixedly connected to the rotating shaft, the first sprocket is fixedly connected to the rotating shaft, and the chain is meshed with the first sprocket.

[0007] As a further improvement of this utility model: a second sprocket is engaged with the inner side of the chain away from the first sprocket, and the second sprocket is fixedly connected to the corresponding second drive shaft and the first drive shaft respectively.

[0008] As a further embodiment of this utility model: the support structure includes a connecting plate, a first support frame, a fixed frame, a first foot pad, a second support frame, a first fixed shaft, and a second fixed shaft. The first support frame is fixedly connected to both sides of the bottom of the connecting plate, and the first fixed shaft is fixedly connected to the bottom of each of the first support frames.

[0009] As a further embodiment of this utility model: a second fixed shaft is fixedly connected to each of the opposite sides of the first fixed shaft, and the two second fixed shafts are fixedly connected by a second support frame. Two fixed frames are detachably connected at equal intervals on the side of the two first fixed shafts away from the second fixed shafts, and a first foot pad is fixedly connected to the bottom of each fixed frame.

[0010] As a further embodiment of this utility model: the first belt conveyor has two second connecting shafts rotatably connected in the middle of its interior. The two second connecting shafts, the second driven shaft, and the second driving shaft all pass through one side of the corresponding first fixed plate and extend into its interior, and are rotatably connected thereto. The second belt conveyor has a first connecting shaft rotatably connected in the middle of its interior. The first connecting shaft, the first driven shaft, and the first driving shaft all pass through one side of the corresponding second fixed plate and extend into its interior, and are rotatably connected thereto.

[0011] As a further embodiment of this utility model: the bottom edges of the first fixing plate and the second fixing plate are both fixedly connected by a control box, and the two power transmission structures are independently controlled by the corresponding control boxes. The motor is located inside the control box, the rotating shaft is rotatably connected to the inner wall of the control box, and the chain passes through the corresponding first fixing plate and the second fixing plate and is adapted to the respective control boxes.

[0012] As a further improvement of this utility model: a main power switch is installed on the upper part of one side of the control box, an indicator light is installed on the side of the main power switch, two plug plates are installed on the side of the indicator light, an emergency stop switch is installed on the side of the plug plates away from the indicator light, and second foot pads are fixedly connected to the four corners of the bottom of the control box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. During use, upon startup, the operator turns on the main power switch through the control box and activates the two independent power transmission structures. After the motor is powered on, the power output shaft drives the rotating shaft to rotate, causing the first sprocket to rotate synchronously. The first sprocket transmits power to the second sprocket through the chain, thereby driving the corresponding drive shaft (first drive shaft or second drive shaft) of the belt conveyor. The drive shaft drives the belt to rotate by the static friction between it and the belt. The driven shaft (first driven shaft or second driven shaft) rotates passively under the action of belt friction, playing a supporting and guiding role. At the same time, the shaft surface is knurled and the belt is made of a high friction coefficient material, thereby realizing the belt circulation and completing the material conveying.

[0015] The two power transmission structures are independent of each other and can be adjusted individually by the control box to meet diverse production needs. At the same time, when the two conveyors are connected end to end, the material relay can be realized through synchronous control to improve the overall conveying efficiency.

[0016] 2. The support structure adopts a multi-set symmetrical layout to ensure uniform load distribution; the fixed frame is connected to the first fixed shaft by bolts to enhance lateral stability and prevent the equipment from shaking during operation; the first foot pad is made of rubber and metal composite material, which has both shock absorption and anti-slip functions, further improving the stability of the equipment during operation;

[0017] 3. The control box integrates a main power switch, indicator lights, circuit boards, emergency stop switches, and other components. An internal control circuit board enables precise control of the power transmission structure. The main power switch controls the start and stop of the motors in a corresponding power transmission structure. External sensors such as belt misalignment sensors, material detection sensors, or host computer systems can be connected via circuit boards to achieve automated control, such as automatically starting and stopping the conveyor based on material detection signals. The emergency stop switch is a critical safety component; in the event of belt jamming, motor overload, or other emergencies, pressing the emergency stop switch instantly cuts off the motor power, immediately stopping the belt operation and triggering a red flashing alarm indicator to alert operators to troubleshoot the fault. The indicator lights can also provide real-time feedback on the equipment's operating status through different colors and flashing patterns; for example, a solid green light indicates normal operation, while a flashing yellow light indicates a warning, facilitating rapid problem location and reducing maintenance costs.
