Technical Field

The invention relates to the technical field of belt conveying, in particular to a synchronous toothed belt conveying mechanism.

Background

The synchronous cog belt is called as synchronous belt, also called as timing belt, and is a flexible transmission form similar to the common belt transmission forms such as V belt, flat belt and the like. In the prior art, a synchronous toothed belt generally takes a steel wire rope or a glass fiber rope as a strong layer, polyurethane or chloroprene rubber is coated outside the synchronous toothed belt, and the inner periphery of the belt is made into a toothed shape so as to be meshed with a toothed belt wheel. The deformation of the strong layer is small after bearing, so that the circumferential section of the toothed belt can be kept unchanged, and the belt wheel do not slide relatively, thereby ensuring synchronous transmission and constant transmission ratio. Compared with the common belt transmission, the transmission mode of the synchronous toothed belt has the following advantages: firstly, because the deformation of a strong layer made of a steel wire rope is extremely small after loading, and the peripheral section of the toothed belt is basically unchanged, the belt and the belt wheel do not slide relatively, and the transmission ratio is constant and accurate; secondly, the toothed belt is thin and light, and can be used in occasions with higher speed, the linear speed can reach 40m/s during transmission, the transmission ratio can reach 10, and the transmission efficiency can reach 98%; thirdly, the structure is compact, and the wear resistance is good; fourthly, the bearing stress is small due to the small pretension force. However, since the toothed belt is meshed with the pulley, the manufacturing and mounting accuracy is required to be high, and a strict center distance is required.

In the prior art, after the synchronous cog belt conveying mechanism is used for a period of time, the synchronous cog belt is worn, and needs to be replaced at the moment. However, since the installation accuracy between the cog belt and the pulley is very high, once the motor (driving mechanism) is misaligned or the axes of the driving wheel and the driving wheel are misaligned after replacement, the meshing effect between the cog belt and the pulley is affected, which not only affects the transmission efficiency, but also causes damage to the transmission mechanism.

In order to solve the technical problems, the chinese utility model patent CN210418064U discloses a flat belt conveying structure, which comprises a conveying profile, a flat belt, a driving mechanism and a driven mechanism; the conveying section bars are arranged in a strip shape; the upper part of the conveying section bar is provided with a conveying channel, the flat belt penetrates through the conveying channel, and a conveying surface is formed above the conveying section bar; one end of the flat belt is sleeved on the driving mechanism, and the other end of the flat belt is sleeved on the driven mechanism; the driving mechanism is detachably connected with the front end of the conveying section bar, the driven mechanism is detachably connected with the rear end of the conveying section bar, and the driving mechanism drives the flat belt to operate. This flat belt conveying structure is provided with actuating mechanism and follower respectively at the both ends of carrying the section bar to actuating mechanism and follower can all dismantle with carrying the section bar and be connected, consequently, when the flat belt needs to be changed, only need lift actuating mechanism or follower off from carrying the section bar, can accomplish the loading and unloading to the flat belt.

However, the above structure, although very convenient for loading and unloading the flat belt, cannot be applied to the timing belt conveyor because: when the belt is replaced, the driving mechanism and the driven mechanism are required to be detached from the conveying section bar, so that when the belt is installed on the conveying mechanism again, the shaft axes of the driving wheel and the transmission bearing are difficult to coincide, and the belt is feasible for a flat belt because the requirement on installation accuracy is not high, but is not feasible for a synchronous toothed belt with high requirement on installation accuracy. In addition, when the flat belt is dismounted or replaced, the flat belt needs to pass through the whole transmission mechanism (comprising a driving wheel and a transmission wheel), the driving wheel and the transmission wheel are arranged on the rack, and the size of the rack is large, so that the flat belt cannot be sleeved in the rack, and the driving wheel and/or the transmission wheel can only be dismounted from the rack, sleeved in a new flat belt and then arranged on the rack; this causes problems of a large number of mounting and dismounting operations and a complicated process.

Therefore, a novel synchronous toothed belt conveying mechanism with a simplified structure and higher precision is developed to simply and conveniently replace the belt, and the synchronous toothed belt conveying mechanism has positive practical significance obviously.
