Translational friction drive

Abstract

The invention provides a translation type friction driving device which comprises a first friction driving mechanism and a second friction driving mechanism that are symmetrically arranged on a driving frame, a driving force driving transmission driving plate between the first friction driving mechanism and the second friction driving mechanism, an elastic component allowing the first friction driving mechanism and the second friction driving mechanism to be close to each other elastically, and a moving component allowing the first friction driving mechanism and the second friction driving mechanism to make back-and-forth movement on the driving frame, so as to allow a driving force to be adjusted when the driving plate swings. The translation type friction driving device can eliminate the swing effect generated when the driving plate moves at a high speed, and vibration is reduced. Compared with a large chain wheel driving mode, a linear motor driving mode and other modes, with the adoption of friction driving, the translation type friction driving device has the advantages of high efficiency, directness in driving, high transfer power and the like, no structural power loss exists, the quantity of required driving units is less on the occasion of the equivalent driving force, and a huge amount of energy can be saved.

Description

technical field [0001] The present invention relates to power transmission technology, in particular to a translational friction drive device used to transmit a drive plate, which is used to drive, for example, a sorting machine trolley, and is especially suitable for power transmission of an article sorting machine. Background technique [0002] Item sorting machines, such as cross-belt sorting machines, are used to sort various small commodities, such as food, cosmetics, clothing, etc., driven by the main drive belt conveyor and a trolley carrying a small belt conveyor (referred to as "Trolley") are connected together, when the "cart" moves to the specified sorting position, it will drive and rotate the belt to complete the task of sorting and sending out the goods. The drive plate is used to drive the sorting machine trolley, and the drive plate is driven by the drive device for translational transmission. The existing drive methods, such as linear motor drive, have small...

AI Technical Summary

Problems solved by technology

The drive plate is used to drive the sorting machine trolley, and the drive plate is driven by the drive device for translational transmission. The existing drive methods, such as linear motor drive, have small transmission power and structural power loss. The number of drive units is large. The drive efficiency is low, and energy is wasted in the daily operation process

And the driving plate will swing during the high-speed transmission process, so the direction of the driving force is easy to deviate from the driving track of the driving plate, resulting in transmission deviation, or wear and tear on the device due to uneven friction

[0003] Generally speaking, different driving boards connected in series are continuously driven and transmitted by the driving device, and there are often gaps between different driving boards, so using the existing driving device, when different driving boards pass through the driving device, Will cause jitter and noise to the drive
