Chain-drive mechanism of heating machine

Abstract

The invention discloses a chain-drive mechanism for warming machine, which comprises a main driving chain wheel, a tightening pulley and a chain composes of a plurality of pitch chains, wherein the chain is arranged one main driving chain wheel and tightening pulley and driven by the main driving chain wheel, two warming heads are equipped at the side end of the pitch chain. The invention fully utilizes spaces among pitch chains to equipped a certain number of warming heads, so as to compact the structure, effectively increase the number of warming heads on the chain, thereby improving production efficiency and saving warming energy. The composite structures between the warming heads and pitch chains and the design that the pitch length of pitch chains is twice than the distance between centers of two warming heads provided in the pitch chains can stabilize transmission during warming and reduce chain vibration, and the chain can perform straight-line transmission without swinging phenomenon. The invention has simple structure and strong practicability.

Description

technical field [0001] The invention relates to a heating machine for heating preforms, in particular to a chain transmission mechanism of the heating machine. Background technique [0002] Generally, during the bottle blowing production process, the preforms are sent to the preform unscrambling machine and then transferred to the heating machine for heating, while the traditional heating machine chain transmission mechanism for heating the preforms is composed of sprockets and a plurality of The chain is composed of a combination of link chains. The chain is installed on the sprocket and the chain is driven by the sprocket. A heating head is installed on the connecting shaft between the link chains. However, this design is suitable for bottles with small pitch and small capacity. As far as the embryo is concerned, the space in the link chain is relatively wasteful, and the manufacturing cost increases, which brings troubles to the production of enterprises. Contents of th...
