Dual-Line Dumpling Wrapping Device with Interchangeable Shaping Molds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dumpling wrapping devices are limited to single-line production, require multiple operators and increased power consumption, and face disruptions and inefficiencies due to varying dumpling sizes and shapes, leading to high production costs and labor requirements.
Innovation Solution
A dumpling wrapping device with a filling provision member distributing fillings to two production lines, each equipped with a wrapping and shaping member, utilizing rotors and positioning members for efficient dough wrapping and shaping, with a centralized control system and adjustable shaping members for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional dumpling wrapping devices are deployed to increase yield, then production capacity increases, but production cost and power consumption increase
Solution Approach 1:
The patent combines two production lines into a single integrated device, allowing two wrapping operations to be performed simultaneously by one operator. The device includes two filling units, two dough units, and two shaping units that work in parallel, effectively doubling the yield while avoiding the need for multiple separate devices and reducing overall power consumption.
Solution Approach 2:
The integrated device performs multiple functions within a single system - it can produce different sizes and shapes of dumplings simultaneously through interchangeable molds, and can operate with a single operator controlling both production lines. This multi-functionality increases yield without requiring additional specialized devices.
2Adaptability or versatility
If molds are replaced frequently to make dumplings of different sizes and shapes, then product variety increases, but production speed decreases and labor requirements increase
Solution Approach 1:
The device incorporates interchangeable molds in both shaping units, allowing a single device to produce multiple varieties of dumplings (different sizes and shapes) without requiring separate dedicated devices for each type. The operator can quickly swap molds between the two shaping units to accommodate different production requirements.
Solution Approach 2:
Multiple molds are pre-prepared and kept ready for quick interchange. The positioning members are designed to facilitate rapid mold replacement, so that when a change in dumpling variety is needed, the operator can simply swap to a pre-prepared mold without extensive setup time, maintaining production speed.
3Reliability
If one output is blocked to handle larger chunks of fillings, then filling unit reliability improves, but the other output becomes blocked due to filling crowding
Solution Approach 1:
The filling unit is segmented into two independent filling delivery systems, each with its own rotor and tube leading to separate wrapping units. This segmentation allows each output to operate independently, so if one output experiences blockage, the other continues to function normally, maintaining overall production continuity.
Solution Approach 2:
The device can adjust the rotor speed and filling delivery parameters independently for each output line. When larger chunks of fillings are encountered, the parameters for one rotor can be adjusted without affecting the other, allowing flexible adaptation to varying filling conditions while maintaining continuous production from both lines.

AI summary
The dumpling wrapping device contains a filling provision member, two wrapping members, and two shaping members. The filling provision member distributes dumpling fillings to feed two production lines of dumplings, each involving a wrapping member and a shaping member. Two pairs of rotors in the filling provision member drives dumpling fillings towards the wrapping members through two tubes. The wrapping members wrap the dumpling fillings from the tubes with dough. The dough wrapped fillings are pressed by the shaping members into dumplings of desired shape and size. Positioning members are configured under the shaping members so that the shaping members can be conveniently replaced and cleaned.
