碩士 / 國立宜蘭大學 / 生物機電工程學系碩士班 / 104 / There are many commercialized shrimp peeling machines available for years. This thesis aimed to develop a prototype one-channel modularized roller assembly to improve the efficiency for replacing worn-out rollers in an existing shrimp peeling machine from a local manufacturer.
The current machine is composed of a three-roller set to do the peeling, in which all rollers are wrapped by plastic coating and turn against each other in operation. The continuous frictions among the rollers, shrimp bodies, and cleaning brushes, produce high worn out rate. Consequently, the rollers must be replaced after a certain period of operation. In the current design of the peeling machine, it is necessary to disassemble many parts before replacing the rollers, making it inefficient and inconvenient for the shrimp processing industry. The need to improve the assembling and disassembling efficiencies motivated this thesis.
In this thesis, the roller set was specifically designed to move along a prescribed rail, such that it can be easily placed and removed. The works for daily maintenance and roller replacing can thus be executed by the user.
In addition, a rolling pneumatic cylinder was used to replace the current four-bar linkage to drive the largest roller for turning movements. The current design reduces the size of the whole machine.
The results show that it only takes an average of 11 minutes for the new design to disassemble or assemble the roller set, much more efficient than the current ones. In shrimp peeling performance, the highest successful rate is 90% for shrimps preprocessed with head-removed and backshell-cut.
