Description

Technical Field

[0001] The utility model belongs to the technical field of filling, in particular to a quantitative filling machine for povidone-iodine solution for aquatic products. Background Art

[0002] Aquaculture is one of the largest sectors in my country's animal husbandry. With the increasing scale and intensification of aquaculture, and the increasing stocking density of farmed animals, the incidence of diseases in aquatic animals has increased, and the conditions have become increasingly complex, some even difficult to control, seriously hindering the healthy development of the aquaculture industry. Using safe and effective disinfectants to kill pathogens in the water and on the surface of farmed animals, thereby preventing the spread of pathogens, is an effective measure to improve the water environment and control aquatic animal diseases.

[0003] Povidone-iodine is a complex of polyvinylpyrrolidone and iodine. It is a non-ionic iodine tincture with iodine as its primary bactericidal ingredient and is currently the most widely used and safest antibacterial disinfectant. Povidone-iodine aqueous solution is a powerful broad-spectrum bactericidal disinfectant with a strong disinfecting effect on viruses, bacteria, fungi, and mold spores. It can also kill parasite eggs in livestock and poultry, and inhibit the breeding of insects such as mosquitoes and flies. It is primarily used for disinfecting livestock and poultry farms, sheds, and the surfaces of aquatic animals. After the povidone-iodine solution is produced, the liquid solution needs to be filled into containers for subsequent use. Therefore, the filling machine is a key piece of equipment in the povidone-iodine solution production process.

[0004] The filling equipment currently used still adopts an extensive production management model when controlling the net content of liquid products. It mainly adopts gravity filling, and controls the filling volume by controlling the time. The filling volume accuracy of this filling method is affected by many factors, and the filling error is large. In addition, in the process of filling liquid medicine into the container, when the filling liquid volume reaches the requirement, the liquid medicine at the liquid outlet of the filling head still drips to the container mouth, and the container is in a state of moving to the next workstation. At this time, the liquid medicine dripping from the filling head is very likely to drip around the inlet of the filling container, affecting the aesthetics of the filling container, and easily causing pollution to the filling container and the production workshop. Therefore, it is urgent to design a quantitative filling machine for povidone iodine solution for aquatic products to solve the above problems. Utility Model Content

[0035] Working principle:

[0036] In the actual working process, the rotary drive cylinder 6-1 is started, driving the valve core in the three-way valve body 6-3 to rotate, thereby connecting the quantitative liquid taking cylinder 8-1 and the liquid source in the quantitative liquid taking device 8, and the piston rod of the liquid taking cylinder 8-3 is retracted, and a quantitative amount of povidone-iodine solution is extracted by the quantitative liquid taking cylinder 8-1, and then the rotary drive cylinder 6-1 is started again, thereby connecting the quantitative liquid taking cylinder 8-1 and the three-way liquid outlet pipe 4-2, and the liquid outlet of the liquid outlet pipe 4-1 is in a closed state;

[0037] After multiple groups of filling bottles are transported to the bottom of each filling head structure 4, the rear drive cylinder 3-3-1 and the front drive cylinder 3-5-1 are started, driving the rear positioning assembly 3-7 and the front positioning assembly 3-6 to move toward each other, thereby clamping the bottlenecks of the filling bottles to achieve the positioning operation of the filling bottles. At this time, the liquid receiving trough 3-8 moves with the front positioning assembly 3-6 to a position that avoids the bottle mouths of the filling bottles, facilitating the filling operation;

[0038] After the rear positioning assembly 3-7 and the front positioning assembly 3-6 clamp the filling bottle, the lifting drive device 9 drives each filling head structure 4 to move downward until the liquid outlet of the liquid outlet pipe 4-1 penetrates into the filling bottle, and then the liquid outlet control valve 4-3 is activated to pull out the plug installed thereon, and at the same time, the liquid extraction cylinder 8-3 is activated to push the liquid in the quantitative liquid extraction cylinder 8-1 into the three-way liquid outlet pipe 4-2 and inject it into the filling bottle through the liquid outlet pipe 4-1 to realize the filling operation; a single filling is completed. After the filling operation, the lifting drive device 9 drives each filling head structure 4 to move upward, and then starts the rear drive cylinder 3-3-1 and the front drive cylinder 3-5-1 again, driving the rear positioning component 3-7 and the front positioning component 3-6 to move away from each other, thereby releasing the clamping operation on the filling bottle. At this time, the liquid receiving trough 3-8 moves with the front positioning component 3-6 to the bottom of each filling head structure 4, and then receives the residual liquid dripping from the liquid outlet pipe 4-1 to prevent the residual liquid from dripping onto the filling bottle and causing contamination.
