Description

Technical Field

[0001] This utility model relates to the technical field of liquid filling, and in particular to a centrifuge tube filling heat sealing device. Background Technology

[0002] Centrifuge tubes are among the most frequently used consumables in disciplines such as biology and chemistry, and are widely used in numerous industries. For example, in education and scientific experiments, centrifuge tubes are used for sample preservation, chemical reactions, biological extraction and separation, bacterial strain preservation, cell and microbial culture, and genetic material amplification. In hospitals, centrifuge tubes are also used for the preservation and analysis of biological and chemical samples.

[0003] After extensive searching, Chinese Patent Publication No. CN207698049U was found, disclosing an automatic centrifuge tube filling machine, including a cabinet; a vibratory feeder, the discharge end of which is connected to a bottle discharge track; a centrifuge tube tray with a centrifuge tube placement slot; a bottle inlet assembly that feeds centrifuge tubes from the bottle discharge track into the centrifuge tube placement slot of the centrifuge tube tray; a filling assembly that fills the centrifuge tubes in the placement slot; a cap flipping assembly that flips the caps of the centrifuge tubes; a capping assembly that presses the caps of the centrifuge tubes onto the centrifuge tubes; a bottle discharge conveyor belt that transports the capped centrifuge tubes outward; and a peristaltic pump that pumps liquid to the filling assembly; the bottle inlet assembly, filling assembly, capping assembly, and bottle discharge conveyor belt are arranged sequentially along the circumference in the rotation direction of the centrifuge tube tray.

[0004] In summary, while existing centrifuge tube filling machines can automatically fill centrifuge tubes, the stability of the centrifuge tubes on the rotating disc during filling is relatively poor, and they are not easy to adapt to the use of different models of centrifuge tubes.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a centrifuge tube filling and heat sealing device, which would have greater industrial application value. Utility Model Content

A hot press head is installed at the bottom of the hot press movable rod. The heat sealing film unwound by the unwinding roller passes under the hot press head and is then rewound by the rewinding roller.

[0015] As a further improvement of this utility model, the heat-sealing film unwound by the unwinding roller is guided by several guide rollers and then wound up by the rewinding roller.

[0016] As a further improvement of this utility model, a limiting seat is installed on the hot press stand, the hot press head is located below the limiting seat, and the hot press movable rod can move freely in the vertical direction within the limiting seat.
