The special lifting and adjusting mechanism for the mouth forming device of the bottle making machine

Abstract

The invention relates to a special lifting adjusting mechanism for a bottle-making machine pressed mouth forming device, wherein the special lifting adjusting mechanism comprises a machine frame, and a driving mechanism for driving a lifting shaft, the lifting shaft and a lifting sleeve which are successively assembled on the machine seat; the top end of the lifting shaft and a base of the pressed mouth forming mechanism are connected into a whole, and output of the driving mechanism is in thread or intertooth meshing connection with the lifting shaft. Through a rotary driving way of thread or intertooth meshing of the driving mechanism, the adjusting mechanism adopts a direct-driving linear adjusting control way for height positioning of the lifting shaft, the displacement amount of the lifting shaft can be accurately adjusted, accurate positioning of the height of the pressed mouth forming device is ensured, and the product qualified rate of pressed mouth forming of a bottle body reaches more than or equal to 98%. The stable and reliable production quality and production efficiency of a bottle-making machine are further improved.

Problems solved by technology

At present, it is used for the lifting adjustment of the mouth forming device of the bottle making machine, mostly by adjusting the hand wheel to drive a set of linkage lever mechanism to realize the lifting adjustment of the mouth forming device of the bottle making machine. The mechanism is mainly composed of the adjustment hand wheel, the guide shaft, The rocker arm, connecting plate and other components form a triangular linkage lever type lifting adjustment mechanism. The lifting adjustment mechanism drives the two rocking arms to rotate through the adjustment hand wheel, and the two rocking arms drive the connecting plates on both sides of the guide shaft to push the pressure port. The bottom plate of the forming device realizes the adjustment of the rise and fall of the die forming device. This structure has the following disadvantages in the height adjustment of the die forming device: first, the adjustment accuracy is low

1. The structure consists of many components and the structure is complex, resulting in a large cumulative error in the transmission between the components, which reduces the accuracy and stability of the lifting adjustment.

2. The uneven force of the transmission parts, especially the uneven driving force of the two rocker arms to the two connecting plates, makes the force on the bottom plate of the die forming device unbalanced, which seriously affects the adjustment of the vertical lift of the die forming device, resulting in The tongs of the crimping device are tilted, and the pass rate of the crimping quality of the bottle body is reduced

3. The transmission link of this structure is too long, and the cumulative error of the combined transmission between components is large, resulting in a decrease in the stability of the transmission process

The adjustment of the height of the crimping device depends entirely on the experience accumulated by the commissioning personnel for many years. It needs repeated adjustments to realize the height requirements of the bottle making machine for the crimping device. Therefore, the adjustment process is not only complicated, but also difficult to adjust. ,Time-consuming
