Engineering Contradiction Analysis
1Area of stationary object
If a traditional layout is used for horizontal high-speed paper cup/paper bowl forming machines, then the machine can perform paper forming, but it occupies a large amount of space and is not organized for efficient space utilization
Solution Approach 1:
The machine is divided into multiple independent modules: a paper feeding mechanism with a turntable, a forming mechanism with a rotation tower, and a crimping mechanism. Each module performs a specific function and can be independently positioned, allowing compact arrangement while maintaining high productivity through specialized functionality.
Solution Approach 2:
The patent introduces a vertical rotation tower structure that operates in three-dimensional space rather than only horizontal expansion. The rotation tower rotates vertically to position forming dies at different heights, enabling multiple forming operations within a compact footprint and improving space utilization efficiency.
2Ease of manufacture
If the main transmission structure is arranged in a traditional manner, then power transmission can be achieved, but it lacks compartmentalization and complicates maintenance
Solution Approach 1:
The transmission structure is segmented into distinct compartments: a drive unit, a rotation tower drive unit, a paper feeding drive unit, and a crimping drive unit. Each compartment contains specific transmission components (gears, belts, shafts) isolated from others, allowing targeted maintenance without disassembling the entire transmission system and reducing overall complexity.
3Reliability
If the paper pressing strip uses an extra power source, then the wrapping process can be stabilized, but it decreases efficiency and complicates control
Solution Approach 1:
The paper pressing strip mechanism is merged with the rotation tower drive system. The pressing strip is driven by the same power source and transmission mechanism that drives the rotation tower, eliminating the need for a separate power source. This integration maintains wrapping stability through coordinated motion while improving efficiency by reducing the number of independent control systems.
4Ease of operation
If the rolling apparatus has a complex structure, then rolling function can be achieved, but it becomes troublesome to assemble and unstable during operation
Solution Approach 1:
The rolling apparatus is segmented into modular components: a rolling wheel assembly, a profiling die assembly, and a support structure. Each module is independently manufactured and assembled, simplifying the overall assembly process. The modular design also improves operational stability by reducing structural complexity and allowing easier alignment and adjustment of individual components.
5Reliability
If the lubrication oil channel is formed in the rolling apparatus, then lubrication can be provided, but it is necessary to prevent the lubrication oil from leaking to the rolling wheel to avoid polluting the paper cup or paper bowl
Solution Approach 1:
The lubrication oil channel is extracted from the rolling wheel area and relocated to the support structure and profiling die assembly. The oil channels are positioned in regions where lubrication is needed for mechanical components but is远离 from the rolling wheel contact zone, preventing oil leakage onto the paper product while maintaining effective lubrication of transmission components.
6Speed
If the rolling wheel is driven by the rolling shaft, then rolling motion can be achieved, but it is very important to ensure the stable operation of the rolling shaft which needs to move axially and rotate concurrently
Solution Approach 1:
The rolling shaft system is segmented into separate functional components: a rotation drive mechanism and an axial movement control mechanism. The rolling shaft is supported by dedicated bearings that separate rotational motion from axial motion, ensuring stable operation. This segmentation allows independent optimization of rotation speed and axial positioning, improving both speed capability and operational reliability.

AI summary
A horizontal high-speed paper cup/paper bowl forming machine is provided. Specifically, the seven-station main rotation tower forming mechanism has a stamping die station, a paper feeding connection station, a first cup bottom preheating station, a second cup bottom preheating station, a bottom crimping station, a rolling station, and a main and auxiliary tower connection station, which are sequentially arranged along a circumferential direction. The seven-station auxiliary rotation tower forming mechanism has the main and auxiliary tower connection station, a cup rim lubrication station, a pre-crimping station, a first final crimping station, a second final crimping station, a cup outlet station, and a reserved vacant station, which are arranged sequentially along a circumferential direction. The stations arranged in sequence along the circumferential direction of the seven-station main rotation tower forming mechanism is in an opposite order to the stations arranged in sequence along the circumferential direction of the seven-station auxiliary rotation tower forming mechanism. The station layout of the forming machine is more reasonable, and the spatial structure is more compact. In addition, a new main transmission mechanism is adopted to match with the forming machine, which is more reasonable and more compact. These provide technical support for subsequent modular assembly. For the turntable paper feeding mechanism, the turntable is driven by the servo motor to realize indexing rotation. The structure is simple, compact, and highly stable to meet the needs of high-speed operation.
