1、 Engineering process

2、 Description

1. Passive unwinding: the non-woven fabric is released passively under the traction shaft of the main machine to avoid friction between the non-woven fabric and the PVC belt to prevent material pollution.

2. Transverse folding: 304 stainless steel folding mechanism, non-woven fabric through the process to ensure that the product is clean and the folding position is accurate.

3. Traction: the servo motor drives fixed-length traction, the length error is controlled at plus or minus 0.1cm, the non-woven fabric is uniformly stressed, and the material is not over-stretched.

4. Cutting: use the upper flying knife and the lower fixed knife to cut. The non-woven fabric cut is neat and free of lint and thread. Quality control method: check the sharpness of the knife edge before work every day, and timely polish and replace it.

5. Packing: the folded and cut non-woven fabric is moved to the packing position of the lower packaging film through the drive roller, and then sent to the liquid filling position through the lower film carrier

6. Add liquid into the bag: PLC controls the liquid filling system with adjustable liquid volume to add liquid regularly. The liquid filling pump uses high-precision electronic diaphragm pump to effectively prevent impurities in the liquid from entering the product. Cover the upper packaging film immediately after adding liquid. Quality control method: the mechanical part adjusts the height of the liquid filling pipe to prevent the liquid from splashing out of the cotton position. The liquid adding time can be adjusted in the touch screen to change the liquid adding amount.

7. Packaging film loading: the loading position can be adjusted, and the packaging film unwinding horizontal manual deviation correction system can control the product edge exposure caused by the paper core position deviation.

8. Marking and feeding: Panasonic full-color recognition photoelectric sensor controls the bag length in strict accordance with the printing layout.

9. Split and align the film: the stainless steel blade is centered to split the packaging film into two layers, and the two layers of materials are respectively through multiple feeding shafts to complete the front and back facing.

10. Bag making and sealing: two vertical and one horizontal sealing are carried out for the dual-temperature control temperature regulating mold, and the pressure and temperature of the sealing mold are adjustable. Quality control method: the sealing patterns of each upper and lower mold are yin and yang. When heating, the alcohol cotton sheet is tightly sealed by occluding the yin and yang sides. The temperature and pressure can be displayed by temperature controller and pressure gauge, so as to accurately control the sealing temperature and pressure and achieve the quality control of sealing effect.

11. Cutting: the upper flying knife and the lower fixed knife are used for cutting. The cutting of the packaging bag is neat without burrs, and the discharge is neat.

12. Cut the dotted line: the packaging film of each piece of alcohol cotton flake is cut between two pieces with a dotted line knife, which is convenient for batch picking and single piece picking.

13. Counting discharge: count the working times of the cutting knife and cooperate with the running motor to discharge the material at a normal low speed. After the number is reached, walk quickly to separate the front and rear groups of materials for convenient collection.
