Solution Overview
Problem
Conventional bottle blowing machines have complex and bulky mechanisms for mould opening and closing, bottom mould elevating, and positioning, leading to operational inconvenience and high costs.
Innovation Solution
A simplified bottle blowing machine design where the mould opening and closing, elevating, and bottom mould positioning mechanisms are driven by a single rotation shaft, utilizing a protrusion, sliding block, and swing members to achieve linkage, reducing the overall complexity and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional separate mechanisms are used for mould opening and closing, bottom mould elevating, and positioning, then each function can be performed reliably, but the device complexity and volume increase significantly
Solution Approach 1:
The patent combines three separate mechanisms (mould opening and closing, bottom mould elevating, and bottom mould positioning) into a single integrated mechanism driven by one rotation shaft. The rotation shaft simultaneously drives the moving mould plate for opening/closing, the elevating rod for elevating the bottom mould, and the locking mechanism for positioning, thereby reducing device complexity while maintaining functional reliability through coordinated motion of all components.
Solution Approach 2:
The rotation shaft serves multiple functions simultaneously: it drives the mould opening and closing motion, elevates the bottom mould through the elevating rod, and controls the locking mechanism for positioning. This multi-functional design eliminates the need for separate drive systems for each function, reducing overall mechanism complexity while ensuring reliable operation of all subsystems.
2Reliability
If conventional separate mechanisms are used for mould opening and closing, bottom mould elevating, and positioning, then each function can be performed reliably, but the overall device volume becomes bulky
Solution Approach 1:
By merging three separate mechanisms into one integrated system driven by a single rotation shaft, the patent significantly reduces the overall device volume. The coordinated motion of the moving mould plate, elevating rod, and locking mechanism all originate from the same drive source, eliminating redundant components and reducing the spatial footprint of the machine.
Solution Approach 2:
The patent employs a nested arrangement where the elevating rod moves through the rotation shaft, and the locking mechanism is integrated within the same drive system. This nesting of components within each other's spatial envelopes reduces the overall volume required for housing all mechanisms compared to separate, distributed arrangements.
3Reliability
If conventional separate mechanisms are used for mould opening and closing, bottom mould elevating, and positioning, then each function can be performed reliably, but the operation becomes inconvenient
Solution Approach 1:
The integration of all three functions into a single rotation shaft driven system means that one primary driving action simultaneously accomplishes mould opening/closing, bottom mould elevating, and positioning operations. This coordinated action simplifies the operation sequence and improves ease of operation while maintaining reliable execution of each function through the mechanical linkage of the integrated mechanism.

AI summary
A bottle blowing machine is provided in the invention. The bottle blowing machine comprises: a machine frame; a mould opening and closing assembly, which comprises a fixed mould plate, a bottom mould, and a moving mould plate rotatably connected with the fixed mould plate by a rotation shaft; an elevating assembly, which comprises a protrusion disposed on the rotation shaft, an elevating rod fixedly connected with the bottom mould and a sliding block fixed on the elevating rod, a guiding groove is opened on the protrusion and the sliding block is slidably inserted into the guiding groove, in the course of rotation of the rotation shaft, the contact position of the guiding groove with the sliding block rises or descends, and the sliding block moves in the up-down direction under the guiding of the guiding groove; a bottom mould locking assembly comprising a plurality of swing members for driving the sliding of the plurality of locking parts; a rotation member for controlling the swinging of the plurality of swing members relative to the machine frame; and a power source for driving the rotation of the rotation shaft. When the mould opening and closing assembly is in the mould closing state, the plurality of locking parts contact against the bottom mould such that the bottom mould is separated from the machine frame.
