Description

A clam-opening device for automatic and continuous feeding in assembly line

technical field

The invention relates to the technical field of electromechanical equipment, and relates to an automatic and continuous feeding and opening device for assembly line operation.

Background technique

At present, my country's pearl industry is developing rapidly, but an important part of its production chain is still purely manual operation, which not only consumes a lot of manpower, increases production costs, but also has low efficiency of opening mussels, and there are hidden dangers in production and occupational disease risks.

The existing mechanized mussel opening devices mainly include the following types: (Among them, only the "Two-way Cutting and Opening Mussel Machine" has obtained the national invention patent authorization)

1. Electric clam opener patent application publication number: CN 102550450 A

The device shocks the scallops with high-voltage electricity, causing the heart of the shellfish to die from the electric shock, causing the adductor muscle to lose its function and open.

This device has a single function, and because the working environment is humid, there is a certain risk of high-voltage electric shock, and the operating efficiency is not high.

2. A cutter for opening clams and extracting pearls Patent application publication number: CN 104472408 A

The device is a tool assembly, which needs to be used with a special device and has certain limitations. If the cutter is used alone, the labor intensity cannot be effectively reduced.

3. Two-way cutting and opening mussel patent authorization announcement number: CN102217667B

The device uses a jig to hold the mussel and uses a knife to cut in both directions.

When this device cuts mussels, it is necessary to manually put a single mussel into the station, and there is only one station. On the one hand, the discontinuous operation leads to low operation efficiency; on the other hand, it can only partially replace manual work, and the mechanical automation level lower.

4. Rotary table open river clam machine Patent application publication number: CN103210993 A

The device uses a stepping motor to drive the clamp on the turntable to the cutting station, and another stepping motor drives the cutter to cut.

This device needs to manually put a single mussel into the processing station, which cannot realize the automatic loading and unloading of mussels, and the operation efficiency is not high, and the level of mechanical automation is low. Therefore, how to improve the efficiency of opening mussels, solve the problem of automatic loading and unloading in the process of opening mussels, and fully realize the automation of opening mussels is an important issue that the mussel breeding industry needs to solve urgently.
