Description

Stable parallel moving mechanism for large-area flat plate

Technical Field

The utility model belongs to the technical field of color printing, packing auxiliary assembly, concretely relates to be used for dull and stereotyped stable parallel translation mechanism of large tracts of land.

Background

In many industrial production fields, equipment for precisely jacking finished products or semi-finished products needs to be used, sometimes, because of large size and weight of the materials, under the condition of equipment structure limitation or power consumption reduction, a steel structure (such as a steel structure frame) with a large scale needs to be adopted for jacking and descending the materials. However, the frame of a general steel structure is easy to deform, so that the corresponding transmission mechanism for precisely transmitting in a single direction of force application direction can bear force in multiple directions, and the transmission mechanism is easy to damage. For example, with the improvement of the living standard of people in China, people have higher and higher requirements on the packaging quality of products, and the color printing technology is basically adopted in the packaging industry at present. In the processes of printing and die cutting the packing box, the multi-layer whole-page packing box after die cutting is generally subjected to waste cleaning and separation by manpower, and waste materials such as leftover materials and the like are removed and decomposed into useful parts of a single finished box so as to conveniently manufacture the finished box. The manual method has high labor intensity and low working efficiency. Moreover, the current packaging process is more and more complex, and the process requirement on the die-cut paper product is more and more high, so that not only peripheral waste materials of the die-cut paper product are difficult to remove, but also waste materials in special shapes are generated in the middle of the semi-finished paper product, and the possibility of damaging and scrapping the die-cut paper product is easily caused by adopting manual waste removal, and the product quality is influenced.

The prior art has mechanical equipment capable of removing wastes, heavy work which needs to be finished manually before can be finished by one to two machines and one to two persons, and the yield, the efficiency and the quality can be greatly improved. For example, japanese patent pin type cardboard separator (JPA 1994238776) separates material cardboard after die cutting by using a group pin capable of being lifted and lowered; the Utility model of Renshenben Enfu also applied for serial patents related to waste cleaning (JPA 1991019795, JPA1991045336, JPA1995148698, JPA 174487). However, these prior art lifting group pins still have some drawbacks, and in order to achieve higher efficiency, a plurality of single molds are generally collected on one lifting platform for lifting, which results in a larger lifting platform. If a single actuator is adopted, because the lifting platform is a steel structure frame and is easy to deform, if a plurality of actuators work simultaneously, the problem of synchronous coordination exists, the process is complex, and the cost is high.
