Speed changing device capable of adjusting feeding length

Abstract

The invention discloses a speed changing device capable of adjusting feeding length. The speed changing device comprises a cam transmission shaft, a power shaft and a sliding shaft, wherein a speed changing chain wheel is mounted on the cam transmission shaft; a multistage speed changing chain wheel is mounted on the power shaft; an adjusting chain wheel is mounted on the sliding shaft; the sliding shaft is mounted on a control panel and is connected to one end of a compression spring; the other end of the compression spring is fixed on the control panel; one end of an adjusting screw rod is fixed on the control panel; an L-shaped rocking handle is mounted at the other end of the adjusting screw rod. Through the speed changing device capable of adjusting the feeding length, the control panel moves forth and back so as to drive the adjusting chain wheel mounted on the speed changing control panel to translate forth and back; the translation of the adjusting chain wheel enables the chain to be engaged with chain wheels with different diameters on the multistage speed changing chain wheel, so that the transmission ratio of the device is changed, thus the speed changing function of the device is achieved.

Description

technical field [0001] The invention relates to a speed change device, in particular to a speed change device which can adjust the feeding length. Background technique [0002] Steel bars and steel strips are steel products with large output, wide application and many varieties, especially in construction and mechanical processing industries. During the production and processing of steel bars and steel strips, products with different lengths or diameters need to be produced and processed. The speed change device that can adjust the feeding length is particularly important in this type of mechanical equipment. In the current market, electrical control is mainly used to realize such functions, but this will cause the equipment to start frequently and have a large impact, resulting in a decline in product quality and serious damage to the equipment itself. Some mechanical speed change devices also exist on the market, but their structures are too complicated, the cost is too h...

Problems solved by technology

In the current market, electrical control is mainly used to realize such functions, but this will cause the equipment to start frequently and have a large impact, resulting in a decline in product quality and serious damage to the equipment itself.

There are also some mechanical transmission devices on the market, but their structures are too complicated, the cost is too high, and the failure rate is high, so they are not suitable for high-load equipment that produces and processes steel bars and steel strips.
