Problems solved by technology

Packages enter the main line under various stresses and speeds, and it is inevitable that packages will roll over (especially cuboid packages), which will cause information such as barcodes to be blocked and affect automatic sorting. It is necessary to increase the manual sorting process before barcode scanning. increase labor cost
The current conveyor belt cannot avoid the tumbling of the conveyed parcels in the confluence section, effectively reducing labor costs

Abstract

The invention belongs to the technical field of conveying belts, and particularly relates to a differential friction coefficient conveying belt and a preparation method and application thereof. The invention provides a differential friction coefficient conveying belt. The differential friction coefficient conveying belt comprises a base belt and a differential friction coefficient surface layer arranged on the surface of the base belt. The differential friction coefficient surface layer comprises a smooth surface layer, a deceleration surface layer and a standing surface layer which are located on the same plane and sequentially arranged in a contact mode in the width direction. The friction coefficient of the smooth surface layer is 0.2-0.4, and the friction pair is a steel plate; the friction coefficient of the deceleration surface layer is 0.55-0.75, and the friction pair is a steel plate; the friction coefficient of the standing surface layer is larger than or equal to 0.9, and the friction pair is a steel plate. The test result of the embodiment shows that the conveying belt with the different friction coefficients can effectively avoid sudden stop and rolling of the conveyed packages in the conveying and confluence working sections, and the packages can be arranged in a specified area.

Description

technical field [0001] The invention belongs to the technical field of conveyor belts, in particular to a conveyor belt with a differential friction coefficient, a preparation method and application thereof. Background technique [0002] With the improvement of the automation level of the logistics and express industry and the advancement of information technology, the requirements for express sorting automation are getting higher and higher. In order to better realize automatic sorting and improve the utilization of site space, express parcels involve multiple Confluence section. When the express parcels are imported into the main line from different branch lines, the speed of the parcels will not decrease, and various angles are involved (30°, 45°, etc.). At the same time, the main line conveyor belt is also running at a synchronous speed. Packages enter the main line under various stresses and speeds, and it is inevitable that packages will roll over (especially cuboid p...
