Novel numerical control mechanical transmission mechanism of slide projector

Abstract

The invention discloses a novel numerical control mechanical transmission mechanism of a slide projector. The novel numerical control mechanical transmission mechanism comprises a slide changing mechanism, a focusing mechanism, a drive mechanism and a drive wheel. The focusing mechanism is arranged on a base of the numerical control mechanical transmission mechanism of the slide projector. The drive wheel is provided with multiple drive blocks which are in transmission contact with a pushing mechanism. The focusing mechanism is arranged on the upper portion of a worm, and a motor and the drive wheel are coaxial. The slider changing mechanism is connected with a friction wheel through a driving shaft. An installation groove is formed in the slide changing mechanism. A piston rod is arranged in the focusing mechanism. The right side of the drive wheel and the right side of a lens tube are provided with dust rings. The numerical control mechanical transmission mechanism of the slide projector is simple in structure, reasonable in design, long in service life, low in cost, and capable of meeting the requirement for conveniently and quickly projecting high-quality files and videos of users.

Description

technical field [0001] The invention belongs to the field of projection equipment, and in particular relates to a novel digitally controlled mechanical transmission mechanism of a slide projector. Background technique [0002] At present, my country's projection equipment is developing rapidly, and there are many kinds of projection equipment, but there are still many problems. The mechanical transmission of large-scale projection equipment is an indispensable work, and most of the mechanical transmission is manually operated by the operator. equipment, but the accuracy of adjustment is limited, the sensitivity is low, the degree of transmission is difficult to control, the degree of stability is low, the ability to grasp the space is relatively low, the controllable range of adjustment is relatively small, the operability is very limited, the degree of automation is low, and the simultaneous operation The slide projector operated by the operator is also quite hard.
