[0002] In the paint shop of some automobile factories, there is a conveyor line that passes through the office area for body conveying. The office area generally requires a quiet working environment without noise, and has high requirements for silence during the body conveying process. At this time, in order to reduce noise, the original chain conveyor will be changed to belt conveyor, and a silent motor will be specially selected. Since the conveyor line passing through the office area is long, sometimes reaching more than 300 meters, the longer the belt conveyor line, the greater the load, and the higher the requirements for the belt; in addition, there will be steel platform expansion joints, fire shutter doors and other dividing positions on the conveyor line, so the belt conveyor line must be divided into multiple sections. However, this type of segmentation often results in a large gap at the transition point between two adjacent belt conveyors. The resulting problems are: first, there is no translational driving force at the transition point, and the goods are easily stuck at the transition point and cannot move, which leads to the accumulation of goods; second, when the goods move to the transition point, the supporting force is discontinuous, causing the goods to vibrate and generate noise.

[0021] See also Figure 1-2The utility model provides a technical solution: a belt conveyor transition device, which is used in a belt conveyor system composed of two belt conveyors connected end to end, and the belt conveyor transition device includes a base frame 1; a power frame 2 fixedly connected to the left and right ends of the base frame 1, each of the power frames 2 includes two support plates 21 arranged at intervals; a rotatable driving sprocket 3 is installed at one end of the two support plates 21, and a supporting roller assembly 31 is installed at the other end; a conveying chain 32 is wound around the supporting roller assembly 31 and the driving sprocket 3, and the driving sprocket 3 can drive the conveying chain 32 to circulate between the two support plates 21, and the part of the conveying chain 32 that is around the top of the support plate 21 is higher than the top of the support plate 21. ; The driven shaft 4 is connected between the two driving sprockets 3; the driven shaft 4 is fixedly connected with a driven sprocket 41; a rotatable driving sprocket 42 is installed on the base frame 1; a driving chain 43 is wound around the driven sprocket 41 and the driving sprocket 42, and is used to drive the two driving sprockets 3 to rotate synchronously when the driving sprocket 42 rotates; the transmission shaft assembly 5 is connected through the center of the driving sprocket 42, and its two ends can be coaxially connected to the two tail wheels at the end of a belt conveyor, respectively, for obtaining power from the tail wheel to drive the driving sprocket 42 to rotate; a hole is provided in the middle of the support plate 21 corresponding to the position of the transmission shaft assembly 5, so that the two ends of the transmission shaft assembly 5 can pass through the power frame 2 and be connected to the tail wheel.

[0022] When in use, the rear tail wheel 71 of the rear belt conveyor 7 behind the conveying direction is connected to the transmission shaft assembly 5 of the belt conveyor transition device. The two power frames 2 are located between the two tail wheels. A conveying belt is wound around each tail wheel, and each belt conveyor uses two circulating belts to convey goods. When the goods arrive at the connection point, one end of the belt conveyor transition device has an overlapping section with the rear belt conveyor 7, so that the goods can be received smoothly. Among them, one of the two rear tail wheels 71 is connected to the driving device 72, and the tail wheel connected to the driving device 72 is connected to the transmission shaft assembly 5 to provide power for the belt conveyor transition device. In other words, the rear belt conveyor 7 and the belt conveyor transition device share a driving device 72, which has a compact structure and saves the number and cost of driving equipment. Among them, the driving sprocket 3, the active sprocket 42 and the driven sprocket 41 ensure that the conveying speed with power transition is close to the original belt conveying speed by selecting an appropriate tooth ratio. When the goods reach the tail wheel 61 of the front belt conveyor 6, one end of the belt conveyor transition device overlaps with the front tail wheel 61 of the front belt conveyor 6, and the goods can be transferred smoothly. Under the drag of the conveyor chain 32 circulating in the middle of the power frame 2, the power for the translation of the goods is not interrupted, and supported by the two conveyor chain belts 32, the supporting force of the goods is also uninterrupted; wherein, the support roller assembly 31 can also be arranged below the conveyor chain belt 32 to support the conveyor chain belt 32.

[0023] An exemplary connection scheme of the transmission shaft assembly 5, the base frame 1 is provided with a seat bearing 11 coaxially arranged with the driving sprocket 42; the transmission shaft assembly 5 includes a linkage shaft 51 coaxially inserted between the seat bearing 11 and the center of the driving sprocket 42; one end of the linkage shaft 51 is connected to a universal shaft 52, and the end of the universal shaft 52 is connected to one of the tail wheels; the tail wheel corresponding to the universal shaft 52 is connected to a driving device 72 for driving the belt conveyor; the other end of the linkage shaft 51 is connected to an output shaft 53, and the end of the output shaft 53 is connected to another tail wheel. It can be seen that the universal shaft 52 is connected to the tail wheel with the driving device 72, which can overcome the coaxial precision error, reduce the vibration caused by the driving device 72 and transmit it to the transition device of the belt conveyor, and reduce noise.

[0024] In order to further reduce vibration noise, the lower end of the base frame 1 is connected to a plurality of support leg assemblies 12; each of the support leg assemblies 12 is fixedly connected to the foundation and includes a vibration isolation element 13 for blocking the vibration of the base frame 1 from being transmitted to the foundation. The vibration isolation element 13 can be a rubber block or a spring. It can be seen that the support leg assembly 12 suspends the main body of the belt conveyor transition device in the air so that the height of the conveyor chain 32 corresponds to that of the conveyor belt, reduces the vibration of the goods, and avoids the vibration from being transmitted to the foundation, thereby reducing the vibration in the surrounding area of ​​the foundation.

[0025] In order to further improve the stability of storing and retrieving goods, the conveyor chain 32 is divided into an output section 33, a transition section 34 and a receiving section 35 in sequence along the direction from the support roller assembly 31 to the drive sprocket 3; the receiving section 35 and the output section 33 overlap and correspond to the positions of the tail wheels of the two belt conveyors respectively; the transition section 34 corresponds to the position of the interval between the two belt conveyors. It can be seen that the output section 33 and the receiving section 35 both overlap and correspond to the belt conveyors, that is, the belt conveyor transition device overlaps and transitions with the two belt conveyors, and the overlapping distance covers the diameter of the tail wheel, and the transition is smoother.

[0026] The advantages of the utility model are as follows.

[0027] (1) This device has overlapping sections with the two belt conveyors, so that the goods always have supporting force and driving force for translation, and the goods are transferred smoothly to avoid jamming.

[0030] (4) The device has a compact structure, is simple to manufacture, and has low cost, making it suitable for application and promotion.
