Description

Technical Field

[0001] This utility model relates to a translational material conveying mechanism, belonging to the field of profile processing technology. Background Technology

[0002] Profiles refer to metal objects that have been plastically shaped and have a specific cross-sectional shape and size. Currently, profiles are used in a large number of industrial production processes, and the handling and loading / unloading of various profiles and other raw materials is a crucial link in production and processing. The operating methods and degree of automation directly determine work efficiency. With technological advancements, the processing of various profiles has become increasingly automated, but it still mainly relies on handling tools such as railcars, conveyor belts, and forklifts. However, the profiles used in industry are large and heavy. When using conveyor belts to transport profiles, the effort to increase the strength of the conveyor belt can easily lead to the conveyor belt itself having high hardness, thus damaging the profiles. Utility Model Content

The parallel support beams are arranged at intervals in the left-right direction. Each support beam has a driven sprocket rotatably mounted at both ends and a driving sprocket rotatably mounted in its middle. Each driven and driving sprocket includes: a spindle, a sprocket portion sleeved on the spindle, and a pulley portion sleeved on the spindle and located on both sides of the sprocket portion. The outer diameter of the pulley portion is larger than the outer diameter of the sprocket portion. The driven and driving sprockets mounted on the same support beam are connected by the conveyor belt, and the sprocket portions of the driven and driving sprockets mounted on the same support beam are connected by a chain, thereby placing the chain inside the conveyor belt that moves synchronously with it.

[0005] The following are further improvements to the above technical solution:

[0006] 1. In the above scheme, the conveyor belt used to contact the workpiece to be conveyed is a felt conveyor belt.

[0007] 2. In the above scheme, several elongated workpieces to be conveyed extend in the left-right direction and each overlaps and contacts the outer surface of each conveyor belt.

[0008] 3. In the above scheme, a first support side plate is installed on each side of the middle part of the support beam, and the two ends of the spindle of the drive belt sprocket located between the two first support side plates are rotatably mounted on the adjacent first support side plate through a bearing seat.

[0009] 4. In the above scheme, the drive unit includes a motor mounted on the base bracket, a reducer connected to the output shaft of the motor, and a synchronous shaft connected to the reducer for transmission. Each of the drive sprocket spindles is fitted on the outside of the synchronous shaft and is in transmission cooperation with the synchronous shaft.

[0010] 5. In the above scheme, the synchronous shaft is a hexagonal shaft.
