A heat sealing method for liquid filling bag filling tube

Abstract

The invention provides a method for low-cost high-safety heat seal of filling bag filling pipes. The method comprises the first step of causing the filling pipes on a filling pipe needing heat seal to be fixedly clamped on a heat seal clamp device, wherein the clamp device comprises a base and a plurality of liquid stopping clamps fixedly installed on the base, the base forms a heat seal side on the sides of the whole liquid stopping clamps, each liquid stopping clamp comprises two opposite clamping parts, and each filling pipe is fixedly clamped between two clamping parts in the same liquid stopping clamp; the second step of feeding the clamp device connected with the filling pipe to a heat seal machine, performing heat seal by the heat seal machine on the filling pipe located on the base, and causing the heat seal side on the base to serve as a heat seal lower die of the heat seal machine to be used; the third step of taking out the filling pipe out of the liquid stopping clamps after the heat seal of the filling pipe is finished. The heat seal working efficiency of the filling pipes can be improved greatly, the heat seal operation human cost is reduced, and heat seal workers are effectively prevented from being scalded by the heat seal machine.

Description

technical field [0001] The invention relates to the technical field of heat sealing processing of liquid filling bag products, in particular to a heat sealing method for filling tubes of liquid filling bags. Background technique [0002] Existing liquid filling bags, such as blood bags, liquid medicine bags, etc., are fixedly connected with filling tubes. After a certain amount of liquid is poured into the filling liquid bags through the filling tubes, it is necessary to seal the filling tubes through a heat sealing process. Install the port to prevent the fluid in the irrigation bag from flowing out of the irrigation bag. [0003] During the heat-sealing process, the heat-sealing operator clamps and seals the port of the filling tube that needs to be heat-sealed with a special liquid-stopping clamp. The operator takes out a liquid-stopping clamp to clamp the filling tube on a liquid filling bag, and then takes it out Another liquid-stopping clamp clamps the filling tube on...

Problems solved by technology

During heat sealing, it is necessary for the heat sealing operator to arrange the filling tube first, then directly fix the filling tube by hand, and then perform heat sealing operation on the filling tube on the heat sealing machine. This heat sealing operation method takes a long time to arrange the filling pipeline, resulting in The heat-sealing work efficiency is low. Moreover, since the filling pipe is directly fixed by hand and then heat-sealing operation is performed on the filling pipe, the hands of the heat-sealing worker are very close to the working surface of the heat-sealing machine. During heat-sealing, the heat-sealing machine working surface is easy to burn the heat-sealing worker Hands, even a skilled heat sealing operator will have burns, so the safety of the heat sealing industry cannot be guaranteed

After heat sealing, the worker removes the liquid stop fixture on the filling tube on site, which may easily lead to messy site stop liquid clamp when removing the clamp, especially for a single bag, which is delivered after heat sealing, and the filling tube is messy, resulting in clamp removal slow down

Usually, in order to meet the GMP clean level requirements when working in the filling workshop, no more than 7 people are allowed to work in the workshop

For the filling workshop with a semi-automatic heat sealing machine, the existing heat sealing process also requires 2 people to fill, 2 people to put the liquid stopper on the filling tube, 2 people to heat the operation, and 1 person to remove the seal on the filling tube after heat sealing. Liquid stop fixture, therefore, the labor cost of heat sealing is high, and the efficiency of heat sealing work is also low
