Description

Technical Field

[0001] The utility model belongs to the technical field of brick blank production and transportation, and particularly relates to a synchronous tensioning mechanism for a brick blank transportation line. Background Art

[0002] After the synchronous belt of the brick blank transportation is used for a period of time, it will be worn, and its length will also be stretched and become loose, resulting in the phenomenon of tooth skipping and non-synchronization. The current design is to adjust the passive wheel shaft and increase the center distance of the wheels on the transportation line to carry out tensioning. When each group of transportation lines consists of multiple synchronous belts arranged side by side, some synchronous belts will be tight and some will be loose, and the tightness is inconsistent, resulting in unstable transportation. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to design a synchronous tensioning mechanism for a brick blank transportation line, which is used to solve the problem that the tightness of multiple synchronous belts is inconsistent and the transportation is unstable as mentioned in the background art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A synchronous tensioning mechanism for a brick blank transportation line, including a chassis, a cross beam, a synchronous belt, a motor, a wheel shaft seat, a wheel shaft, a gear ring and a tensioning mechanism. A cross beam is provided at the upper end of the chassis. Wheel shaft seats are provided at both ends of the cross beam. Wheel shafts are respectively arranged in the two wheel shaft seats. One end of one of the wheel shafts is matched with the motor. Gear rings are arranged at intervals on the wheel shafts. Synchronous belts are arranged between the corresponding gear rings on the two wheel shafts. A tensioning mechanism is provided on the synchronous belt.

[0005] The tensioning mechanism includes a support plate, a connecting shaft, a connecting plate, a tensioning wheel and a counterweight. The number of the support plates is two. The two support plates are respectively fixed in the middle of the two cross beams. A connecting shaft is arranged between the two support plates. A connecting plate is arranged on the connecting shaft. A tensioning wheel and a counterweight are arranged on the connecting plate.

[0006] A bearing is provided in the middle of the connecting plate and is sleeved on the connecting shaft through the bearing and is rotatably connected with the connecting shaft. The tensioning wheel is arranged at one end of the connecting plate, and the counterweight is arranged at the other end of the connecting plate. The connecting plate rotates on the connecting shaft so that the tensioning wheel is in contact and cooperation with the synchronous belt.

[0007] The tensioning wheel is provided with a pin shaft and is fixed at one end of the connecting plate through the pin shaft.

[0008] Edges are provided on both sides of the wheel body of the tensioning wheel, and the distance between the two edges is greater than the width of the synchronous belt.

[0009] The number of the connecting plates is multiple, and the number of the connecting plates corresponds to the number of the synchronous belts.

[0010] The beneficial effects of the present utility model are as follows: After adding an independent tension pulley to each synchronous belt, according to the lever principle, using a counterweight can keep each synchronous belt in a tensioned state at any time, and the tension force remains consistent, enabling each group of conveyor belts to operate smoothly.

The tensioning wheel 9 is arranged at one end of the connecting plate 7. The counterweight 10 is arranged at the other end of the connecting plate 7.

[0016] When the present utility model is in use:

[0017] The middle part of the connecting plate 7 is rotatably connected with the connecting shaft 8 through a bearing. According to the lever principle, the position of the bearing is equivalent to the fulcrum of the lever at this time, the connecting plate 7 is equivalent to the rod body of the lever, and the counterweight 10 at one end of the connecting plate 7 is the downward acting force. Under the action of the counterweight 10, the tensioning wheel 9 at the other end of the connecting plate 7 is lifted upward. Since the tensioning wheel 9 is in contact and cooperation with the synchronous belt 3, the synchronous belt 3 is always in a tensioned state. Each synchronous belt 3 that is also in a tensioned state keeps the conveying stable.
