Problems solved by technology

[0002] With the spread of culture and the development of society, the printing technology is becoming more and more mature, so the use of the printing machine is convenient. In order to prevent accidental injury during the operation of the printing machine, the printing machine is equipped with protective equipment, which can not only protect The parts in the printing unit are not exposed, and can achieve the purpose of safety protection, so the existing printing unit of the printing machine is equipped with protective equipment, but the protective equipment of the printing unit of the printing machine in the prior art, because the protective equipment is a sliding design , and due to the large amount of dust in the printing factory, when the equipment stops running, the protective cover moves to both ends of the slide rail, and the slide rail is exposed to the outside world, resulting in continuous accumulation of dust and impurities in the slide rail, resulting in the pulley at the bottom of the protective cover When moving with the slide rail, it will continue to bond with the impurities and dust in the slide rail, causing the pulley to be affected by the impurities and dust, thereby increasing the friction between the pulley and the slide rail, resulting in intermittent movement of the protective cover. snapping phenomenon

Abstract

The invention provides printing unit protection equipment of a printing machine. The printing unit protection equipment structurally comprises an observation window, a machine body and a base, wherein the observation window is embedded into the inner side of the machine body; and the lower end surface of the machine body is welded to the upper end surface of the base. According to the printing unit protection equipment, in a process that a protection cover drives a pulley to rotate, the pulley is composed of a connection ring and a rotary disc, and outer rings of the connection ring and the rotary disc are mutually extruded with the inner side of a movable mechanism, so that rotary devices in the movable mechanism are extruded with the connection ring and the rotary disc respectively; the rotary devices are arranged at the bottom end of a slide rail at equal distance, friction blocks in the rotary devices are made of rubber materials and the surfaces of the friction blocks are designed into a concave-convex pattern shape; and when extruded, the friction blocks are recessed, so that impurities on the surfaces of the outer rings of a connection disc and the rotary disc are scraped off, and furthermore, the circumstance that the pulley is influenced by the impurities and dust so that the friction force between the pulley and the slide rail is increased, and intermittent clamping in a movement process of the protection cover is avoided.

Description

Technical field [0001] The present invention relates to the field of printing techniques, in particular a printing machine printing unit protection device. Background technique [0002] With the development of culture and the development of society, the printing technology is increasing, so the printing machine is convenient, and the printing machine is to prevent accidental injury during operation, so it can protect the printing machine, not only protecting the printing machine The components within the printing unit are not exposed, and the purpose of safety protection can be achieved, and therefore the existing printing machine printing units have a protective equipment, but the printer printing unit protective equipment in the prior art, due to the protective equipment for sliding design Due to the large amount of dust in the printing plant, the protective cover moves to both ends of the slide, the slide is exposed to the outside, causing the slide to accumulate dust and impu...
