Express sorting machine comprising cam and worm for driving

Abstract

The invention provides an express sorting machine comprising a cam and a worm for driving. The express sorting machine comprises a machine frame, trolleys and a trolley driving device. The trolleys and the trolley driving device are mounted on the machine frame. The trolley driving device controls advancing of the trolleys. The trolley driving device comprises the worm, the cam and a worm driving device. The cam is spirally fixed to the worm. Each trolley comprises a base, two side plates, a conveying belt, two roller devices, a conveying belt driving device and a transmission device, wherein the two side plates are fixed to the two sides of the base in parallel; the two ends of the two roller devices are connected with the two ends of the two side plates to form a rectangle; the conveying belt surrounds the outer sides of the two roller devices; the conveying belt driving device is mounted on the base and controls operation of the conveying belt; the transmission device is mounted on the base and connected with the trolley driving device. The express sorting machine is reasonable in structural design, good in conveying and transferring effect, safe, reliable, low in manufacturing cost, stable in goods conveying and accurate in sorting.

Description

technical field [0001] The invention relates to an express sorting machine using cam and worm drive, which is mainly used for transporting and sorting goods. Background technique [0002] The express sorting machine applies program control and electronic scanning technology, which is specially used for the automatic conveying and sorting of postal express goods, and automatically distributes the express goods to the required regional address. The express sorting machine in the prior art is generally driven by a motor chain sprocket, and also has a motor pulley. Off-chain, and affect the accuracy of transmission; motor pulley transmission requires the application of rack and pinion, the mechanical structure is more complicated, and the manufacturing cost is high. Can not meet the ideal application effect. [0003] The express sorting machine is dedicated to the automatic delivery of postal express goods to ensure accurate delivery and sorting of express goods. The trolley ...

AI Technical Summary

Problems solved by technology

The express sorting machine in the prior art is generally driven by a motor chain sprocket, and also has a motor pulley. The chain is off and affects the accuracy of transmission; the motor pulley transmission requires the application of rack and pinion, the mechanical structure is more complicated, and the manufacturing cost is high

In the prior art, the trolley of the sorter is generally flip-shaped, unloading and transporting to the branch transmission system. The defect is: the flip-shaped unloading is easy to shift the goods, and the transfer to the branch transmission system will not be in place, which will affect the accuracy of the transmission. , can not meet the ideal application effect
