Abstract

The utility model relates to a bi-pitched hybrid main chain transmission structure, which comprises a drive-in or a detaching main chain sprocket, and a paper collecting sleeve tension wheel. It is characterized in that the model is also provided with an enclosed chain ring which is provided with small-pitched chain on the main chain sprocket and the tension wheel, and is provided with large-pitched chains on the other paths; the enclosed chain ring is made up of same two bi-pitched hybrid main chains connected with each other. The utility model adopts the bi-pitched hybrid main instead of the traditional equal pitched chain to reduce about 1/3 weight of every chain and reduce about 40% tensile deformation. The utility model improves the paper advance precision, i.e. the paper die cutting precision because of the reduction of the tensile deformation of the main chain.

Description

The hybrid main chain bar of a kind of bipatch drive mechanism

Technical field

The utility model relates to the die-cutting machine in a kind of printing machinery, relates in particular to the hybrid main chain bar of the bipatch drive mechanism in the die-cutting machine.

Background technique

Traditional main chain bar structure such as is at the pitch chain, and these pitch main chain bar tensile buckling amounts are big, and weight is big than hybrid combination.The paper feed precision that causes because of tensile buckling declines to a great extent, thereby influences the mould-cutting precision of paper.

Therefore, provide a kind of overall weight that can reduce the tensile buckling of main chain bar, alleviate the main chain bar, the main chain bar drive mechanism that improves the mould-cutting precision of paper is one of the applicant's content of endeavouring to study.

The model utility content

The purpose of this utility model is to provide a kind of hybrid main chain bar of bipatch drive mechanism that can alleviate main chain bar gross weight and reduce the tensile buckling link.

The hybrid main chain bar of a kind of bipatch provided by the utility model drive mechanism, comprise and drive in or run quickly and to overlap Idle wheel with collection portion from main chain wheel, it is characterized in that: it also comprises the chain ring of a sealing, wherein, this chain ring is arranged the fine pith chain at main chain wheel and Idle wheel two places, arranges the coarse pitch chain on remaining stroke.

In the hybrid main chain bar of above-mentioned bipatch drive mechanism, the chain ring of sealing uses two hybrid main chain bars of identical bipatch to connect and forms.

Owing to adopted above-mentioned technical solution, promptly the utility model adopts the hybrid main chain bar of bipatch, and than pitch chains such as tradition, every weight saving is about 1/3, and tensile buckling reduces about 40%.The utility model main chain bar has improved the paper feed precision because of having reduced the tensile buckling amount, has promptly improved the mould-cutting precision of paper.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the plan view of the hybrid main chain bar of bipatch in the utility model;

Fig. 3 is the plan view of the hybrid main chain bar of bipatch in the utility model.

Embodiment

The hybrid main chain bar of the utility model bipatch drive mechanism, every die-cutting machine uses two hybrid main chain bars of duplicate bipatch, and utilizing chain hinge pin is the chain ring of a sealing with its connection, constitutes drive mechanism.

Shown in Fig. 1～3, driving in or running quickly and locate to arrange fine pith chain 31 for 2 liang from main chain wheel 1 and collection portion cover Idle wheel, arrange coarse pitch chain 32 on remaining stroke, arrange that the fine pith chain is to utilize polygon effect that main chain wheel and Idle wheel are enclosed bag, improve stability of transmission; Arrange that the coarse pitch chain can reduce tensile buckling amount, weight reduction.

Though the utility model main chain bar drive mechanism is described with reference to current instantiation, but those skilled in the art should be realized that, above example only is to be used for illustrating the utility model, also can make the variation and the modification of various equivalences under the situation that does not break away from the utility model spirit.Therefore, if in connotation scope of the present utility model to the variation of above-mentioned example, modification all will drop in the scope of claims of the present utility model.
