AI Technical Summary
Traditional speed reducers cannot meet the speed ratio requirements of downward-folding equipment, especially when multiple belt drives are involved, they cannot achieve a consistent speed ratio.
A sliding reversing reducer was designed. By setting an input shaft, an output shaft, and a long keyway, the power input shaft can move left and right. The distance between the two can be adjusted to meet the requirements of different sized cardboards, and synchronous transmission can be achieved through bevel gear connection.
This allows for belt replacement without disassembly, saving maintenance time and costs, and meeting the speed ratio requirements of the downward bending equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper box processing technology, specifically a sliding reversing speed reducer. Background Technology
[0002] When preparing paper boxes for a folding production line, one main power source on the folding equipment needs to drive two main belts and two auxiliary belts. The speeds of the main belts and auxiliary belts must be consistent, and the speed ratio of the main belts to the auxiliary belts must be 1:2. This requires the use of a speed reducer. Power is provided by an electric motor. After the speed reducer adjusts the rotation speed, the power reaches the actuator through chain drive or gear drive to realize the folding action.
[0003] However, traditional speed reducers have the following disadvantages:
