Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying technology, and in particular to a synchronous belt conveyor. Background Technology
[0002] Synchronous belt conveyors, as a type of material handling equipment, are used to move materials from point A to point B, thereby connecting different processes on the production line and realizing continuous and automated production. However, commonly used conveyors generally adopt a "drum friction traction" structure: using a three-phase asynchronous motor with a fixed speed ratio or equipped with a mechanical reducer as the power source, the output speed is basically fixed or only has step speed regulation, making it difficult to achieve accurate speed control. The power source transmits power to the drive drum via a V-belt or chain, and the synchronous belt is driven by the friction between the outer surface of the drive drum and the inner surface of the synchronous belt. Although it is low in cost and simple in structure, the following shortcomings have been exposed in long-term operation: 1) Low and unstable transmission efficiency: It relies on friction transmission, which is subject to slippage and loss of transmission efficiency; 2) Speed is not adjustable or can only be stepped: The number of poles of a three-phase asynchronous motor is fixed or the mechanical reduction ratio is fixed, and the speed is fixed and the linear speed cannot be adjusted in real time according to the cycle time of the preceding and following processes, thus failing to meet the requirements of precise speed regulation. Utility Model Content
[0003] The purpose of this invention is to provide a synchronous belt conveyor that meets the requirements for precise speed regulation by using a speed-regulating motor, and at the same time, the transmission mechanism uses a bevel gear transmission assembly for transmission, which has high transmission efficiency and stability.
[0004] To achieve the above objectives, the following technical solution is adopted: A synchronous belt conveyor includes a frame, a speed-regulating motor, a transmission mechanism, and at least one synchronous belt mechanism mounted on the frame. The transmission mechanism includes a transmission shaft connected to the synchronous belt mechanism and a bevel gear transmission assembly connected between the speed-regulating motor and the transmission shaft. The speed-regulating motor drives the bevel gear transmission assembly via the transmission shaft to drive the synchronous belt mechanism to achieve the conveying function. The rotating shaft of the speed-regulating motor and the synchronous belt mechanism are both arranged along the X-axis direction, and the transmission shaft is arranged along the Y-axis direction.
[0005] Preferably, the synchronous belt mechanism includes a synchronous belt drive assembly, a synchronous belt tensioning assembly, and a synchronous belt connected between the synchronous belt drive assembly and the synchronous belt tensioning assembly; the drive shaft is connected to the synchronous belt drive assembly.
[0006] Preferably, the synchronous belt drive assembly includes a synchronous drive wheel, a first flat key connecting the synchronous drive wheel and the drive shaft, and a first retaining ring for preventing the synchronous drive wheel from moving axially; the end of the drive shaft is detachably connected to the frame body via a first mounting plate; and the synchronous drive wheel is sleeved on the drive shaft.
[0007] Preferably, the synchronous belt tensioning assembly includes a tensioning wheel axle, a synchronous tensioning wheel sleeved on the tensioning wheel axle, and a second retaining ring for preventing the synchronous tensioning wheel from moving axially; both ends of the tensioning wheel axle are detachably connected to the frame body via a second mounting plate.
[0008] Preferably, the top of the frame body is provided with a wear-resistant strip for each synchronous belt; the top of the wear-resistant strip is provided with a guide groove extending through both ends along its length, and the synchronous belt moves through the guide groove.
[0009] Preferably, a roller assembly is provided below each timing belt to assist the movement of the timing belt; each end of the roller assembly is detachably connected to the frame body via a third mounting plate.
[0010] Preferably, the belt-driven roller assembly includes a belt-driven roller shaft core, a belt-driven roller shaft sleeved on the belt-driven roller shaft core, and a bearing disposed between the belt-driven roller shaft and the belt-driven roller shaft core; the belt-driven roller shaft is arranged along the Y-axis direction and contacts the bottom of the synchronous belt.
[0011] Preferably, there are two synchronous belt mechanisms; each end of the drive shaft is connected to a synchronous belt mechanism.
[0012] Preferably, a protective cover is provided on the outside of the transmission mechanism, and the protective cover is located between the two synchronous belt mechanisms.
[0013] Preferably, the bevel gear transmission assembly includes a driving bevel gear connected to the rotating shaft of the speed regulating motor, a driven bevel gear sleeved on the transmission shaft, a retaining ring for fixing the driven bevel gear, and a second flat key disposed between the driven bevel gear and the transmission shaft; the driving bevel gear and the driven bevel gear are meshed together.
[0014] By adopting the above solution, the beneficial effects of this utility model are: This utility model provides a synchronous belt conveyor that uses a speed-regulating motor to meet the requirements of precise speed regulation, and the transmission mechanism employs a bevel gear transmission assembly for high and stable transmission efficiency. In a preferred embodiment, by setting wear-resistant strips on the synchronous belt and creating guide grooves, the synchronous belt can move in a specified direction, avoiding friction between the synchronous belt and the frame. Furthermore, a belt drag roller assembly assists the synchronous belt in returning to its origin, thereby enabling repetitive operation. Attached Figure Description

[0021] The synchronous belt drive assembly 41 includes a synchronous drive wheel 411, a first flat key 412 connecting the synchronous drive wheel 411 and the drive shaft 31, and a first retaining ring 413 for preventing the synchronous drive wheel 411 from moving axially.

[0022] The tension of the synchronous belt 43 in the front-to-back direction is adjusted by setting up a synchronous belt tensioning assembly 42. The synchronous belt tensioning assembly 42 includes a tensioning wheel shaft 421, a synchronous tensioning wheel 422 sleeved on the tensioning wheel shaft 421, and a second retaining ring 423 to prevent the synchronous tensioning wheel 422 from moving axially.

[0030] The synchronous belt conveyor provided by this utility model uses a speed-regulating motor 2 to drive a bevel gear transmission assembly to convert the rotational electrical energy (rotation shaft) in the X-axis direction into rotational mechanical energy (transmission shaft 31) in the Y-axis direction, thereby driving the synchronous belt drive assembly 41 to drive the synchronous belt 43 to move on the synchronous belt wear strip 5 in a specified direction. Finally, the synchronous belt 43 passes through the synchronous belt tensioning assembly 42 and then returns to the origin via the belt dragging assembly 6, thus realizing repetitive work.
