Description

Technical Field

[0001] The utility model belongs to the field of fish packaging, in particular to an adjustable counterweight device for fish packaging. Background Art

[0002] When packaging fish, it must be packaged and vacuum-sealed according to customer specifications, with labeling including the production date, product name, manufacturer and registration code, weight specifications, and batch number. More importantly, ensuring the correct weight of the packaged fish requires adjusting the counterweight during packaging. Generally, the weight deviation should not exceed 3%.

[0003] In comparison, the Chinese patent with announcement number CN220843169U discloses an adjustable counterweight device for fish packaging, including a feeding hopper, one end of the feeding hopper is fixedly connected to a box body, a transmission mechanism is provided inside the box body, one end of the transmission mechanism is provided with a material guide piece, one side of the box body is fixedly connected to a discharge hopper, one side of the box body is provided with an adjustment mechanism, the surface of the adjustment mechanism is provided with a weighing plate, the weighing plate is electrically connected to a display, and the surface of the adjustment mechanism is provided with a coating mechanism.

[0004] However, after the fish meat weighting is completed in the above patent, the machine needs to be stopped and the fish meat needs to be taken out before weighting can be adjusted again, which slows down the speed of adjusting the weight of fish packaging. Moreover, the weight can only be increased but not reduced during weighting, making it difficult to ensure the accuracy of the fish meat weighting adjustment. Therefore, a new device needs to be designed. Utility Model Content
