Description

TECHNICAL FIELD

[0001] The present application relates to the field of mask packaging, in particular to a mask packaging method. BACKGROUND

[0002] The mask refers to a device worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets from entering and exiting the wearer's mouth and nose. The mask has a certain filtering effect on the air entering the lungs, and has a very good protective effect when wearing a mask in the respiratory tract infection epidemic and in the dust and other polluted environment.

[0003] The packaging bag of the mask is generally made of medical dialysis paper and plastic film. The medical dialysis paper and plastic film are sealed by four seals, and the mask is placed in the hollow cavity. The dialysis paper and plastic film of this structure are usually equal in length and width, which requires more medical dialysis paper and has high cost. Secondly, the traditional medical dialysis paper is generally made of wood pulp after dehydration to make dialysis base paper, and then a layer of heat-seal adhesive is applied on the dialysis base paper. Since the wood cellulose of the dialysis base paper cannot be heat-sealed with other high molecular materials, the heat-seal adhesive is needed to seal with the high molecular material. There are two types of heat-seal adhesives. One is solid hot melt adhesive, which has a large amount of adhesive, high cost, poor air permeability, thick adhesive layer, easy to stick to the contents, and slow coating speed, low production efficiency, which cannot meet the needs of production. The other is water-based heat-seal adhesive. Since it uses anilox coating, the speed can reach 100 m / min, the adhesive coating dry weight is greatly reduced, the air permeability is good, and the production cost is low. However, this adhesive has poor heat-seal strength stability, low strength, and the packaging is easy to drop the lint during opening, which affects the product quality of the sterilization packaging bag.

[0004] The mask packaging method of the prior art is to put one mask into a packaging bag that has been pre-sealed in three directions and only one sealing opening left, then seal the last sealing opening, and then put them into a packaging box by workers one by one for further packaging, and finally put the boxed masks into a packaging box one by one for stacking. Using this packaging process, the unsealed opening of the packaging bag needs to be opened, and then the mask is put into the packaging bag, which has low packaging efficiency.

[0005] Chinese Patent No. 202010662100.6 discloses a full-automatic packaging bag opening and sealing processing technology, including the following steps: step one, packaging bag unwinding, the packaging bag roll located in the packaging bag output box is pulled by the discharge roller located on one side of the packaging bag roll, and the packaging bag is horizontally output along the discharge channel on the packaging bag output box; step two, pre-opening bag, when the horizontally output packaging bag is conveyed to the gap between the cutting roller group and the pressing roller which are parallelly arranged at the end of the discharge channel, the cutting roller group and the pressing roller rotate in opposite directions at different speeds, so that the end of the opening of the packaging bag is stretched to form a horn mouth, and the outer diameters of the cutting roller group and the pressing roller are consistent; step three, cutting, after the cutting roller group rotates for one revolution, the cutting blade located in the cutting roller group extends from the cutting roller group towards the pressing roller, and cuts the connection part of the packaging bag and the packaging bag roll; step four, opening bag, the opened packaging bag is sleeved on the opening bag assembly opposite to the discharge channel, the symmetrical suction plates on the opening bag assembly are driven by the pushing assembly to slide away from the length direction of the mounting plate, so that the sleeved packaging bag is stretched, and when the suction plates slide away, the air bag located between the suction plates is stretched, so that the packaging bag is adsorbed on the side wall sleeved with the suction plates; step five, unlocking, after the packaging bag completes the stretching work, the unlocking block on the suction plate and the touch block on the locking unit on both sides of the length direction of the mounting plate are in contact, so that the locking unit releases the connection between the mounting plate and the second rotating support; step six, rotating direction changing, the opened packaging bag is driven by the first rotating drive and the second rotating drive respectively, so that the packaging bag is first rotated by 90° along the X axis, and then rotated by 90° along the Z axis, the opening of the packaging bag after the direction changing is arranged upwards and located directly above the conveying line arranged on the adjacent opening bag assembly; step six, pushing into the box, the packaging bag after the direction changing is pushed vertically downward by the pushing assembly, and the mounting plate is separated from the second rotating support, so that the packaging bag is pushed into the fixed box located directly below; step seven, bag opening positioning, after the packaging bag is pushed into the fixed box, the first rack mounted on the mounting plate is engaged with the first gear on the fixed box, the positioning plate is turned over to cooperate with the magnetic attraction stone to fix and limit the bag opening of the packaging bag through the rotation of the first gear; step eight, bagging, after the bag opening of the packaging bag is fixed and limited, the fixed box is transferred to the position directly below the feeding mechanism on the conveying line through the conveying of the conveying line, and after the fixed box is sensed by the photoelectric sensor on the feeding mechanism, the electric discharge valve is controlled to start, and the feeding box feeds the packaging bag in the fixed box; and step nine, sealing, after the feeding is completed, the fixed box is transferred to the position directly below the sealing mechanism on the rear side of the feeding mechanism through the conveying of the conveying line, and the opening of the packaging bag in the fixed box is heat-sealed by the sealing mechanism. SUMMARY

[0006] Therefore, in view of the above problems, the present invention provides a method for packaging masks, which solves the problem of low packaging efficiency in existing mask packaging methods.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a method for packaging face masks, comprising the following preparation steps:

[0008] (1) Selection of packaging materials: The main packaging materials are heat-adhesive medical dialysis paper and polypropylene film;

[0009] (2) Preparation of packaging bags:

[0010] a. The medical dialysis paper is unwound and transported online, the first heat-adhesive polypropylene film is unwound and transported online, the second heat-adhesive polypropylene film is unwound and transported online, and the first heat-adhesive polypropylene film and the second heat-adhesive polypropylene film are respectively transported and laminated to both sides of the medical dialysis paper. The first heat-adhesive polypropylene film, the medical dialysis paper and the second heat-adhesive polypropylene film are transported at the same speed.

[0011] b. First hot-pressing process: Hot-press the first heat-adhesive polypropylene film and the medical dialysis paper at the composite point to fix them together, and hot-press the second heat-adhesive polypropylene film and the medical dialysis paper at the composite point to fix them together, to obtain a continuously transportable unfolded packaging bag.

[0012] (3) Packaging of masks: The continuously transported masks are transferred online to the continuously transported unfolded packaging bag; the first heat-adhesive polypropylene film and the second heat-adhesive polypropylene film on both sides are folded upward and inward to cover the mask, and the free ends of the first heat-adhesive polypropylene film and the second heat-adhesive polypropylene film are attached to form the first opening to be sealed.

[0013] (4) Online hot-press sealing: The first opening to be sealed is hot-pressed and sealed;

[0014] (5) Longitudinal sealing: The direction perpendicular to the transmission direction is defined as longitudinal. The continuously transmitted unfolded packaging bag is longitudinally sealed at equal intervals, and then cut along the perimeter of the seal to form individual items.

[0015] A further improvement is as follows: The preparation method of the first hot-melt self-adhesive polypropylene film is as follows: (i) using 100 parts by weight of amorphous polypropylene, 10-20 parts by weight of SEBS, 5-15 parts by weight of terpene resin, 2-5 parts by weight of phenolic resin, and 0.1-5 parts by weight of crosslinking agent as raw material components; (ii) feeding the raw material components described in step (i) into a melt extruder for melt extrusion and granulation; (iii) casting, cooling and shaping to obtain the first hot-melt self-adhesive polypropylene film.

[0016] A further improvement is that the preparation method of the second heat-adhesive polypropylene film is the same as that of the first heat-adhesive polypropylene film.

[0017] A further improvement is that the temperature of the melt extruder is controlled at 80-200℃.

[0018] A further improvement is that the overlap width between the first heat-adhesive self-adhesive polypropylene film and the medical dialysis paper in step a is 1-3 cm.

[0019] A further improvement is that the hot pressing temperature in step b is controlled at 70-120℃.

[0020] A further improvement is that the terpene resin is a terpene resin modified with organosilicon.

[0021] A further improvement is as follows: The specific process of organosilicon modification is as follows: Toluene is added to the terpene resin, stirred evenly, and then a catalyst and trichlorosilane are added and reacted for 5-6 hours. Then methanol is added to remove the remaining organic solvent.

[0022] A further improvement is that the weight ratio of the terpene resin to toluene, catalyst, trichlorosilane, and methanol is 1:1-1.2:0.01-0.02:0.8-0.9:1.

[0023] A further improvement is to control the reaction temperature at 50-75℃.

[0024] By adopting the aforementioned technical solution, the beneficial effects of the present invention are as follows:

[0025] 1. The first heat-adhesive self-adhesive polypropylene film and the first heat-adhesive self-adhesive polypropylene film of the present invention are both made of amorphous polypropylene, SEBS, terpene resin, phenolic resin and crosslinking agent as raw material components. The film made using the above formula can generate adhesive force at 70-100°C and can achieve adhesive fixation when laminated with medical dialysis paper without the need for additional glue coating. The preparation process is relatively simple.

[0026] 2. The packaging bag of the present invention has a three-part packaging structure, namely, it is composed of medical dialysis paper and a first heat-adhesive polypropylene film and a second heat-adhesive polypropylene film on both sides, forming a packaging bag structure with three openings. After the pre-prepared masks are transferred to the unfolded packaging bag, the first heat-adhesive polypropylene film and the second heat-adhesive polypropylene film on both sides are folded upward and inward to cover the mask, forming a first sealing opening. After the first sealing opening and the two longitudinal sealing openings are sealed, the packaging bag is cut to form individual packaged masks. The packaging bag with this structure is simpler to package. Compared with the traditional four-part packaging (i.e., a square packaging bag with two sealing openings in both the longitudinal and transverse directions), the packaging process is simpler. It is not necessary to use a packaging bag opening device or manually open the packaging bag to put on the mask, and the packaging efficiency is higher.

[0027] 3. The terpene resin of the present invention is modified with phenol resin, which enhances the polarity of the terpene resin and enables it to be fused with polypropylene and SEBS, thereby improving the thermal adhesion of the packaging bag.

[0028] 4. The first heat-adhesive self-adhesive polypropylene film of the present invention does not require the addition of solvents and will not cause pollution to the environment.

[0029] 5. Furthermore, the terpene resin of the present invention is a terpene resin modified with organosilicon. The specific process of organosilicon modification is as follows: toluene is added to the terpene resin, stirred evenly, and then a catalyst and trichlorosilane are added and reacted for 5-6 hours. Then methanol is added to remove the remaining organic solvent. The packaging bag obtained by modification in this way has moisture-proof properties. Attached Figure Description
