Description

Technical Field

[0001] This utility model relates to the technical field of conveyor belt conveying devices, and in particular to a mid-drive conveyor with an encoder. Background Technology

[0002] In school experiments and practical training courses, as well as in some industrial settings, conveyor belts are required to transport workpieces. Existing conveyor belt systems occupy a large space and have low integration, significantly limiting their application in experimental and training schemes and industrial site layouts. Most existing conveyors are single-side drive conveyors, which may lead to uneven tension on the conveyor belt. Over long-term operation, this can accelerate wear on the belt edges. Furthermore, single-side drive conveyors may experience uneven tension distribution (high tension at the drive end and low tension at the far end) during long-distance transport, causing the conveyor belt to sag or deviate, requiring additional tensioning devices.

[0042] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0043] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
