Description

Anti-jamming chain width adjusting assembly Technical Field The utility model relates to the technical field of reflow soldering equipment, in particular to an anti-jamming chain width adjusting assembly. Background The reflow oven is equipment which enables solder paste to be heated and melted so that surface-mounted components and parts and PCB bonding pads are reliably combined together through solder paste alloy, objects in the reflow oven are subjected to material conveying operation through two chains, and are synchronously fixed through a material seat and the two chains, so that the material seat is driven to move along with the movement of the chains to realize material conveying, however, the volumes of the material seats are different under different demands, and therefore, the width of the two chains needs to be adjusted according to the volumes of the material seats. When the main chain of the chain is adjusted in place and the driven chain wheel is not in place in the width adjusting process of the chain, the chain wheel and the chain are in a horizontal inclined state at the moment, the chain can possibly fall off from the corresponding chain wheel in a horizontal dislocation mode, the blocking phenomenon is generated, and the width adjusting device needs staff to predict the transverse adjusting distance of the two chains by means of a measuring tool when the two chains are adjusted in width, and then the width adjusting operation of the chain is realized through a driving unit, so that the operation is complex.
